The present invention relates to an improved method of and apparatus for ballasting railway ties.

After prolonged subjection to the pounding and compressing effect which results from passage of locomotives and cars over Vrailroad tracks, the ballast underlying the supporting ties is displaced laterally and then upwardly between the ties until the supporting foundation is substantially destroyed. Heretofore, it has been common practice to restore the ballast to a position underlying the ties by impacting tools operated from above the upper surface of the ties at an angle inclined to the plane thereof so as to generally direct the movement of ballast toward the area beneath the ties.

However, the conventional spacing of ties is not suflicient to permit the tool to assume an angle of much in excess of 45 from the vertical with the result that a large part of its power is wasted in driving the ballast d'ownwardly into the sub-grade rather than horizontally into position to support the ties. Furthermore, the irnpacting` action is, of itself, objectionable because of its tendency to crush and pack the ballast thereby interfering with drainage and frequently occasioning washing away of the ballast with attendant undermining of the road bed. In addition, hard spots are formed which injure the ties because of lack of uniform distribution of bearing surface.

It is accordingly an important object of this invention to--provid'e a new and improved method of and machine for ballasting railroad ties in which the force utilized to restore the ballasting material to supporting position beneath the ties acts in a substantially horizontal plane underlying the plane defined by the bottom surface of the ties.

Itis another object of the invention to provide a novel method of and machine for ballasting railroad ties in which a non-percussive as distinguished from an impacting force is utilized to restore the ballast to a position underlying the ties.

A further object of the invention is the provision of a novel method of and machine for ballasting railroad ties in which ballast is impelled' in two directions from a position between adjacent side walls of the ties, and below the plane defined by their under surfaces, to a position underlying the ties; the ballast immediately above that which was displaced being caused' to move downwardly under the influence of gravity into a position to be acted upon by the impelling means.

Yet another object of the invention is to provide a ballasting machine comprising a plurality of impelling vanes arcuately movable in a horizontal plane and vertically adjustable from a position above the plane of the ties to a position below the plane defined by the bottom surface of the ties. A,

It is another object of the invention to provide a ballasting machine comprising a plurality of iinpelling vanes and improved means effective to move the vanes toward and away from a position underlying the plane defined by the bottom surface of the ties and parallel with the longitudinal axis of the ties.

A more specific object of the invention is the provision of a ballasting machine such that they vertically movable element which constitutes the support for the impelling vanes may also be employed as a mounting for the prime mover thereby eliminating the necessity of employing dead-weight counterweights to force the vanesupporting element to its lower or operative position. l

Other objects and advantages will become apparent from the following description taken in connection with the accompanying drawings, in which:

Fig. 8 is a detailed sectional View of an impelling vane and its associated operating shaft.

In the embodiment of the invention selected for purposes of disclosure, the mechanism of the ballasting machine is carried on a car I0 comprising end and side frame members II, I2, I3 and I4 upon which is mounted a suitable enclosing cab I5. A pair of trucks I6 and I'I support the car for movement along rails I8 carried on cross ties I9, an auxuliary set of wheels being employed to move the car from the rails when occasion demands.

A structural cross head 2| (Fig. 4) of I-beam cross section as indicated in Fig. l, is slidably supported in similar inwardly facing vertically disposed channel beams 22, the channel beams in turn being mounted on the side frames I3 and III of the car. Vertical movement of the cross `A Pllo head 2l is effected by mear'is of a pair of air cylinders 23 mounted on the respective side frames of the machine and operatively connected .Y

pivotally connected at 21 to the ends of the crossv head.

A plurality of spaced, vertically disposed shafts 28 (Fig. 8) are journaled in the cross head 2| for movement about their respective longitudinal axes. In this instance the cross head has integrally formed therewith a plurality of bearings 29 to receive the shafts 28, the shafts being restrained against downward movement in the bearings by integrally formed heads 36 which engage the upper end surfaces of annular collars 3l interposed between the upper ends of bearings 28 and heads 38. In the embodiment of the invention selected for purposes of disclosure, ve such bearings and shafts have been illustrated but it will be understood that a lesser or greater number might be employed.

Driving connections effective to produce simultaneous arcuate or rotary movement of the shafts 28 are provided. Referring to Figs. l, 3, 4, 5 and 6, .a lever 32 having oppositely extending arms 32a and 32b is rigidly attached to the central one of the shafts 28 with the upper surface of an integrally formed collar 33 in bearing engagement with the lower end of the shaft-bearing so as to prevent upward displacement of the shaft relative to the bearing.

The remaining shafts 28 are provided with lever arms 34, 35, 36 and 31 having collars 34a to 31EL respectively, the adjacent levers preferably, although not necessarily, extending in oppositedirections from the vertical plane common to the axes of the several shafts as illustrated in Fig. 6. The levers 34 and 31 are connected to the similarly extending arm 32a of the lever 32 by means of a link 38 whereas the levers 35 and 36 are connected to the arm 32b by means'of 'a link 39. v

An alternative means of interconnecting the several shafts 28 so as toveffect rotary movement is illustrated in Fig. 4, In this instance the upper ends of the respective shafts are provided with beveled gears 48 which mesh with corresponding gears 4| carried by an overlying drive shaft 42 rotatably supported on the upper end of the cross head.

The weight of the prime mover from which power is derived to actuate the drive shafts 28 augments the force acting to' move the cross head 2l to its lower or operative position. To this end an internal combustion engine designated 43 is mounted upon a bracket 44 formed integrally with, or rigidly connected to, the cross head 2l. In the embodiment of the invention illustrated in Fig. 1 the engine 43 is drivingly connected to a compressor 45, supported on a bracket 46 rigid withthe cross head 2| by means of a chain 41, the weight of the compressor thereby contributing to the force tending to move the cross head downwardly. The compressor 45 is effective to Vcharge a compressed air reservoir 48 through a flexible conduit 49, the reservoir being carried on the frame of the car. A piston' and cylinder device 58, the cylinder of which is pivotally supported on a lug l rigid with the cross head, is drivingly connected to the several shafts 28 through the medium of piston 52 and crank arm A53, the lever arm in this embodiment of the inventon being h'nrtatably connected to the upascisse per end of that one of the shafts 28 which Kis adjacent the side frame I4 is viewed in Fig. 2.

In the alternative construction shown in Fig, 4, the engine 43 is drivingly connected to the shafts 28 by means of a chain 54 operating on suitable sprocket wheels rigidly connected to the engine `drive shaft and shaft 42 respectively. A jaw clutch 55 adapted to be operated by a hand lever 56 effects engagement and disengagement of the engine with the shaft.

Operation of the shafts 28 is automatically initiated in the construction shown in Figs. l, 2, 3, 5 and 6 by means operable as an incident to the lowering of the ballasting mechanism tooperative position. Referring to Fig. 5 a valve 51, which is interposed betweenV a conduit 58 and a flexible hose 59 communicating with the air reservoir 48 and the piston and cylinder device 52 respectively, is effective to automatically control a flow of compressed air from the reservoir to the cylinder. Y

A valve operating arm 68, the outer end 'of which is provided with an anti-friction roller 6|, is spring pressed into engagement with a cam surface 62 rigid with and arranged vertically upon the cross head 2|.

When the cross head-is moved to its upper or inoperative position, the valve 51 is closed through the action of' arm 60 in contacting a depressed portion 63 of the cam 62 whereas when the cross head is moved to its lower or ballasting position as illustrated in Fig. 5, the roller 6i of the arm 60 will contact a raised portion 64 of the cam'thereby rotating the valve to its open position to permit a flow of compressed air to cylinder 50 thereby automatically effecting reciprocating movement of the piston 52 which, through its connection with the crank arm 53 operates to arcuately oscillate all of the several shafts 28. Y

The invention contemplates apparatus effective to move ballast from a position between the ties and below the plane defined by their under surfaces to a position underlying the ties. To this end the oscillatory arcuate movement of the k shafts 28 is utilized to force ballast in two directions from a series of 'pointsrin the crib between adjacent ties and below the plane defined by their under surfaces, toward the area underlying the ties. Referring to Fig. 8, the shafts 28 will be seen to depend below the respective collars of the lever arms 32 and 34 to 31 inclusive, their respective depending ends having ballast impelling elements 65 non-rotatably and detachably secured thereto.

In the present embodiment of the invention, the lower ends of the shafts 28 are milled at 66 to provide a non-circular cross section which is adapted to be received in a recess of corresponding contour in the upper end of the element 65. A pin 61 projecting through the telescoping portions of element 65 and the lower end of the shaft 28 further serves to provide a nonrotatable connection between the two and removal of the pin permits of ready disengagement of the parts.

. Formed integrally with the lower end of element ated on by the elements associated with th'ose particular shafts to move under the ties at points directly beneath the rails.

Referring to Figs. 1 and 3, the ballasting elements 65 are shown in outline in their lower or operating positions while Fig. 7 diagrammatically indicates the approximate extent of arcuate movement of the ballasting elements. It will be obvious, particularly from an analysis of Figs. 1 and 7 that ba-llast'in contact with the faces of the respective surfaces 68 will be impelled toward the area underlying the ties through the arcuate movement imparted tor those surfaces through the shafts 28. When the elements 65 are rotated by means of the driving connections shown in Fig. 4, the ballast will similarly be impelled normally to the longitudinal dimension of the ties to force the ballast into position beneath the ties.

To insure uniform distribution of ballast throughout the entire length of the area underlying the ties, the cross head 2| and consequently each of the shafts A28 and their respective elements 4555 are reciprocated horizontally when the cross head is in its lower or operating position, the extent of reciprocatory movement in each direction (as indicated in Fig. 3) being equivalent to onehalf of the distance between adjacentY elements 65. Furthermore, it is contemplated that this reciprocatory traversing of the space between the elements 65 will be initiated and terminated automatically asl the cross head is moved to and Vfrom operative or ballasting position.

Referring particularly to Figs. 2, 3 and 4, it will be seen that thevertical channel members 22, which guide the cross head 2 I` for vertical sliding movement, are of relatively deep construction thus permitting bodily shifting of the cross head in the plane of Fig.,3 without effecting its disengagement from therespective channels. Referring to Figs. 3 and 4, a speed reduction unit 69 comprising a worm 10 drivingly connected to engine 43, meshes with a worm wheel 'l I. A crank arm l2, rigid with the worm wheel 1| is pivotally connected to a link 13, the opposite end of which is pivoted to a crank arm '14. Referring to Fig. 1, the crank arm 'I4 is pivoted to a bracket 'l5 which, in turn, is rigidly attached to the frame of the car. The pivotal connection between link 'I3 and crank arm `Hl forms the axis of an antifriction roller 16 which lies in the vertical plane of a laterally extending shoulder 11 formed integrally with the bracket 15, and a horizontal portion 'I8 of the bracket 44.

When the prime mover 43 is in operation, and the cross head 2| in its upper or inoperative position, the crank arm 12 is rotated at a relatively slow rate of speed and this rotary movement is communicated through the downwardly inclined link 13 to crank arm 14 which idly oscillates between positions on either side of the vertical. As the cross head moves downwardly, link 'I3 approaches a horizontal` position and in doing so, shifts bodily to the right to such an extent that oscillation of arm I4 becomes limited to an arc extending in a clockwise direction from the vertical.

Thus, when surface 18 contacts roller 16, the arm 14 will inevitably extend upwardly and to the right of its pivot and as the cross head completes its downward movement the roller 16 will be constrained between surface 18 and shoulder 11 of bracket 15 in which positionit virtually acts as a xed pivot for link 13, thereby causing the cross head itself to move under the influence of crank arm 12.

It will be obvious that as the cross head is elevated to inoperative position, roller 16 will be released and arm 14 will again idly oscillate in response to rotation of crank 12, the cross head meanwhile coming to rest.

The ballasting mechanism is adapted to be propelled along the rails I8 from crib to crib by means of an air engine 19 (Fig. 1) rigidly attached to the frame work of the car and drivingly connected to the truck I6 by means of chain and sprocket wheels 80.

Compressed air is piped from the reservoir 48 to the engine 59 through conduit 8l and control valve 82.

The car may be elevated from the rails to permit the placing of an auxiliary pair of short rails in underlying position with respect to the trucks 20, the car thereafter being lowered until the trucks 28 are in bearing enga-gement with the auxiliary rails thereby permitting removal of the machine from the tracks for any desired purpose.

The elevating means in this instance comprises four air cylinders and pistons 83 connected with the source of air pressure in the reservoir 48 by conduits 84 and control valve 85. The cylinder and piston devices 83 are, as indicated in Fig. l, normally urged to their upward or retracted position by means of coil springs 86 surrounding the respective pistons within the cylinders, and acting between the lower end of the cylinder and the piston proper to force the piston rod to its upper position.

Compressed air is conveyed to the cross head elevating cylinders 23 from the valve 82 through conduits 81, the air pressure being utilized solely to elevate the cross head, its weight being depended upon to effect a downward movement to ballasting position. Any desirable form of blocking means may be employed to support the cross head in its upper position when the machine is not in service.

It will be observed that all functions of the machine are adapted to be controlled by valves 82 and 85 which are located in close proximity in one end of the cab thereby insuring ease of operation and'flexibility of control.

Prior to commencing operation of the machine, the parts will occupy the positions shown in Fig. 1 with the cross head and its associated tamping elements in elevated position above the crib. The prime mover is set in motion to charge the reservoir 48 with compressed air from compressor 45. Thereafter the cross head is lowered under the iniiuence of gravity until the ballasting elements have reached the position shown in outline in Figs. 1 and 3. At the time the surfaces 68 of the ballasting elements Contact the upper surface of the ballast in the crib, the camming surface '64 on the cross head operates to rotate the arm 60 of valve 51 to initiate operation of the piston and cylinder device 5U, thereby oscillating shafts 28 and consequently elements 65 and surfaces 68 as the combined weight of the cross head, prime mover and compressor act to drive the ballasting elements to their extreme lower position.

Simultaneously with initiation of movement of elements 65, the roller 'I6 is acted upon by surface 'I8 to cause the cross head toassume a norizontal movement in the plane of Fig. 3, this movement reaching its maximum proportions when the cross head is in its lower position. The horizontal movement of the cross head is suincient in this position to insure reballasting of the ties throughout their entire lengths.

CII

It will be seen that the reballasting operation is accomplished without resortingl to an impacting action and kthat the force imparted by the Vanes to the ballast is effectivev to drive the latter in a horizontal plane to a positionl underlying the-ties. Furthermore it will be seen that the loperation of the device is such that only a single raising land lowering action is necessary in the cross head at each crib to be reballasted so that the weight of the prime mover may be utilized to drive the cross head to its ballasting position without involving the possibility of movement of the cross head impairing the prime mover.

. Furthermore, the non-percussive character of the operation of the device prevents deterioration of the prime mover and eliminates the possibility of hard spots being formed in the ballast. The action of the cross head in traversing the ballasting elements longitudinally of the ties effects an even distribution ofrballast throughout the length of their bearing surfaces. Y
