12 Claims.

This invention relates to improvements in railway tie treating or creosoting apparatus.

In the relaying of railway track rails it is customary to adze the upper surfaces of the ties to receive the tie plates upon which the rails are then laid. In this operation the rail at one side is removed, the ties adzed and plates laid, and the rail replaced, following which the rail at the other side is removed and replaced in the same manner. The freshly adzed ties must be treated with creosote, or other preservative, before the plates are laid and heretofore this has been a time consuming task as well as one which is wasteful of creosote and likely to cause damage to the workers clothes or injury to his skin. This is for the reason that the creosote has been applied by a swab or broom from a pail so that the material is unevenly distributed over the ties and comes in contact with the workers clothes and skin.

In accordance with my invention I provide an apparatus by which a predetermined quantity of creosote or similar material may be applied evenly over the newly adzed surfaces of the ties, without waste and without possibility of coming into injurious contact with the operator. Another object is to provide an apparatus for this purpose which is simple, compact and readily operated and wherein both the quantity of creosote and the area over which it is spread may be readily adjusted to meet various conditions. Still another object is to provide in such an apparatus a heating means to heat the creosote and facilitate its flow, particularly during cold weather, and a pump located so that it will properly handle the material and take it from the tank at the point whereat fullest advantage is received from the heat applied to the material.

These and other more detailed and specific objects will be disclosed in the course of the following specification, reference being had to the accompanying drawings, in which- Fig. 1 is an end View of my improved apparatus illustrating the same in use and. in position for creosoting a freshly adzed tie.

Fig. 2 is an enlarged plan view, partially broken away of the apparatus as seen in Fig. 1.

Fig. 3 is an enlarged side elevation of the swinging spray nozzle alone.

Fig. 4 is an enlarged vertical cross sectional view taken along the lined-4 in Fig. 2.

Referring now more particularly and by reference characters to the drawing, l indicates a cylindrical tank which constitutes the main body of the apparatus and serves to contain and carry 2 the creosote or other treating and preserwng material, with which the tank is filled through an opening covered by the cap II.

Adjacent its end the tank It) is provided with pairs of transversely spaced, depending brackets 12 between which are journaled small flanged wheels l3 adapted to travel one of the rails M of the track. Longitudinally extending hand rails or bars l5 are provided along the upper side of the tank It! and by grasping these, at either end, a workman may push the tank along the rail M as required.

Arranged lengthwise in the lower part of the tank is a heating duct or pipe I6 which opens at one end I! through one end I8 of the tank. The other end l9 of the duct I6 is closed and terminates short of the opposite end 20 of the tank. To provide a draft through the duct this closed end 19 thereof is provided with an upright stack or pipe 2| which communicates with the interior of the duct and opens upwardly through the top of the tank. A heater or burner 22 is positioned within the open end of the duct It and is here shown as a generator type of burner to which fuel is supplied from a tank 23 through a fuel line 24. The tank 23 is mounted near one end of the tank I0 upon a {plate 25 secured to the hand rails l5. The burner 22 is supported upon a base bracket 26 secured between the adjacent Wheel brackets l2, and circular shield or cover 21 is removably secured by screws 28 over the base bracket to protect the exposed end of the burner.

A pump, designated generally at 29, is positioned centrally and vertically in the tank l0 and comprises a cylinder 30 havin an inlet 3| in its lower end with which cooperates a check valve ball 32. A cage 33 limits upward movement of the ball 33 upwardly from the inlet 3|, said cage being secured to the end 30 of the cylinder by screws 35. Above this inlet valve structure the cylinder 30 has a discharge opening 36 in one side and communicating therewith is :a pipe 31 which leads upwardly from the cylinder and emerges at its upper end above the tank [0. The pump further includes a piston 38 to which is attached a plunger or rod 39 extending upwardly from and through the top of the tank.

The upper end of the pump cylinder 33 has a cap 30 to which is secured an upright tubular guide 4| loosely receiving the plunger 39 and at its upper end this guide t! is provided with a gland member 42 through which the plunger passes. A large opening 63 in the top of the tank w clears the ump a p 1 and a o r 3 44 is removably mounted on this opening. The pump being secured to this cover 44, as designated by the welded connection 45 between the guide M and cover, may be removed as a unit when the fasteners 40 (Fig. 2) for the cover are removed.

A tubular screen 41 encloses the pump 29 and hangs from the cover plate 44 down to the bottom of the tank. The screen and pump both depend clear through the duct I6 which is apertured on upper and lower sides for this purpose and provided with a sleeve 48 welded in place, to pass the screen and keep the creosote from entering the duct.

A frame or boom structure 49 extends laterally from one side of the tank I and comprises two similar trussed side members 50 and I provided adjacent the tank with clips having upper and lower apertured ears 52 and 53 overlying the outwardly turned and complementarily apertured flanges of a section of a structural beam 54 welded, or otherwise suitably secured to the tank side. Pins 55, having eyes 59 at their upper ends, are passed through the apertured ears and flanges to releasably anchor the side members 50 and 5| to the tank while permitting horizontal swinging movements of the members relative to the tank.

The outer ends of the side members 50 and SI are bifurcated at 51 to engage a horizontal mounting plate 58 secured to and extending from a spray hood 59. These bifurcated ends 51 are pivoted to the plate 58 by removable bolts 60 and, as will be clearly evident in Fig. 2, the parallel motion of the side members 50 and 5| will .permit the hood 59 to be swung in a horizontal plane substantially paralleling the tank and without twisting or turning the hood from its position with respect to the tank. The plate 58 has a series of openings EI (Fig. 2) to receive the bolts 60 and to permit the hood to be adjusted, toward and away from the tank, or to adjust the distance from the rail I4, traveled by the tank, to the hood.

The hood is generally rectangular in shape having a large open bottom. 62 and upwardly converging sides and ends terminating in a smaller top opening 63. Extending upwardly from opposite sides of the upper opening or mouth 63 are uprights or standards 04 and 65 which are joined at upper ends by a handle 60, these standards being spaced apart in the direction of travel of the apparatus. A brace rod 6'! is pivoted at 68- at its outer end to a cross bar 69 between upper end portions of the standards 64 and 65 and extends inwardly or toward the tank, the inner end being pivoted at to an upper end of a post or upright angle II welded atop the tank I0 near its center. Thus the standards are held against vertical tilting movements while the horizontal swinging movement of. the hood is in no way interfered with.

The pump 29 is operated by means of a hand lever I2 which is pivoted at E3 between the standards 64 and 55 and swings up and down outwardly thereof. A crank finger I4 forms a part of the hand lever I2 and pivoted thereto by a bolt'I5 is the outer end of a link rod I6 which extends toward and over the tank I0. A bell crank TI is fulcrumed at 18 upon one side of the post II and has an upwardly extending arm 79 to the upper end of which is pivoted at 80 one end of a short link M. The other end of this link BI is then pivotally attached at 82 to the link rod I9 and the two pivots 80 and 82 are disposed with their axes at right angles to permit complete freedom of movement of the link rod 16 both as a result of operation of the hand lever I2, and during the swinging movements or adjustments of the hood. 59. The remaining arm 83 of the bell crank 11 extends over the exposed end of the pump plunger 39 and a link 84 is pivotally connected at 85 and 86 to these parts. The crank finger I4 has a series of openings 87 to receive the bolt 15 to adjust the pump stroke in a readily apparent manner.

The range of upward and downward swinging movements of the hand lever "I2 is limited by means of a yoke 88 (Fig. l) which is connected by a bifurcated link 89 to the lower end of the crank finger I4. The yoke 88 loosely encircles a cross pin 90 supported by brackets 9I between the standards 64 and 65 and limits the swinging movements of the crank finger M.

A swinging spray nozzle 92 is provided and comprises a nozzle section 93 (Figs. 1 and 3) which pivots on a coupling section 94 with a passageway 95 connecting the interiors of these parts in a conventional manner. The nozzle is supported immediately over the upper opening 03 of the spray hood 59 by connection of the, coupling section 94 to a nipple 96 secured to and through a cross bar 91 extending between the standards 64 and 65. The nozzle section 93 is thus supported for swinging movements in a vertical plane, parallel with that through which hand lever I2 swings, and said nozzle section is provided with an ear 98 to which the lower end of a turnbuckle connecting or operating link 99 is pivotally connected at I00. The other end of the link 99 is pivoted at IOI to the hand lever 12. At both ends the link 99 is adjustable by series of openings IOI and I02 in the ea'r98 and a, bar I03 inthe lever I2 and such adjustments, plus the length adjustment of the link 99 provided by its turnbuckle formation permits a wide range of adjustment of the arc through which the nozzle is swung by operation of the hand lever as will be readily apparent.

Liquid from the tank I0 is supplied to the spray nozzle 92 by a flexible hose I04 which at one end is connected through a hand valve I05 to a check valve I06 connected to the upper end of the pump discharge pipe 31. The check valve I96 permits flow of the liquid into the hose but prevents. back flow into the pump. At its other end the hose is connected through a drain cock I01: and an elbow I08 to the nipple 96 supporting the. nozzle.

Operation In operation the apparatus is moved along one rail I4 of the track so that the hood 59 travels in succession across the ties I09 and at a distance from the rail I4 corresponding to the position at which the other rail (not here shown) is located. Thus the hood. may be, positioned over the freshly adzedsurfaces IIO of the ties I09 and the hood, is of such shape and size as to nicely cover and enclose these surfaces IIO. One man ordinarily pushes the tank I0 along the rail at .a steady pace, and. another man grasps. the handle 65 to position the hood, the parallel motion of the frame 49. permitting the hood to be brought to rest for a moment over each tie and permitting minor adjustment of the hood exactly on each tie without swinging the hood out of parallel therewith. The hand lever 12 is urgeddownwardlyas the hood settles on the tie and thismotion, rocking the bellcrank "I1, urges the pump piston 38 downwardly to deliver a charge of creosote from the pump through the pipe 31 and hose I04 to the spray nozzle 92. The nozzle sprays the creosote, or other liquid heavily down through the hood 59 and the swinging movement of the nozzle, by downward movement of the hand lever, delivers the spray evenly across the full area of the adzed surface H of the tie. The hand lever I2 is then raised, in the normal action of lifting the hood 59 for travel to the next tie and this operation, by swinging bell crank 11, pulls the pump piston 38 upwardly and draws another charge of the liquid into the pump cylinder 3!]. As the hood then reaches the next tie, this charge of liquid is delivered thereto by the down movement of the hand lever as just described. It will be evident, therefore, that the ties may be treated rapidly and effectively, and that the material is evenly distributed without waste or possibility of contact with the workmen.

The treating material is, furthermore, delivered in an exactly metered charge each time, and the volume of each charge may be readily varied to suit conditions by changing the connection 15 to the crank finger 14 which has the eifect of varying the length of stroke of the pump piston 38. Likewise the length of the arc traveled by the spray nozzle may be varied as heretofore described, to control the area over which the material is applied.

The heating of the material by the burner 22 facilitates its proper flow and in this connection it will be noted that the pump inlet 3| is located immediately adjacent the heat circulating duct l6 so that the pump takes the material from a location where the material has thoroughly heated. In cold weather the hose i0 1 may be drained by opening the drain cock I01 and by loosening the check valve I06 to permit air to enter the hose at that point. Then to prevent the hose from being accidentally pumped full again the valve I85 may be closed until the ap-- paratus is used again.

The pump 29 being submerged in the liquid in the tank not only receives the liquid at its warmest but is always primed and is itself warmed so that it operates freely in the coldest weather.

It is understood that suitable modifications may be made in the structure as disclosed, provided such modifications come within the spirit and scope of the appended claims.
