2,996,016 Patented Aug. 15, 1961 In the embodiment of my invention illustrated in the accompanying drawing the tamping unit illustrated is essentially that disclosed in the Corwill Jackson application filed September 27, 1955, Serial No. 536,886, Patent No. 2,795,198, issued June 11, 1935, but it is desired to point out that tamping units such as are illustrated in the Jackson Patent 2,482,111 might be used. However, tamping units of this general type are an element or factor of my invention of substantial importance.

Referring to the drawing, 1 represents the ballast of a road bed, 2 the ties and 3 the rails. The carriage designated generally by the numeral 4 is provided with front and rear flanged wheels 5 and 6, the rear wheels 6 being mounted on a driven axle 7. The driving or power means for the axle is generally indicated at 8 but it is not described as it forms no part of the present invention. The operators platform 9 is supported on the frame 4 in elevated position relative to certain other parts of the machine and is provided with an operators seat 10.

As the machine is moved from tie to tie in use a brake shoe 11 is provided for one of the wheels 6, the brake being operated by the hand lever 12 positioned at the side of the platform 9 to be manipulated by the operator seated in the seat 10. The mounting of the brake shoe and the operating lever connections may be conventional and are therefore not described in detail. 13 represents an engine and 14 a hydraulic pump operatively associated with the engine. 15 and 16 represent hydraulic tanks. As the details of these parts form no part of the present invention they are not further illustrated or described herein.

The carriage is provided with uprights or standards 17 on which the crosshead or frame cross member 18 is mounted. This cross member 18 constitutes, in addition to a support for certain structural elements, an instrument panel for various control units. The machine comprises means for raising the rails and the ties and for tamping the ballast while the rails and ties are in raised position, this tie and rail raising means being characterized by the fact that one rail and one end of the tie may be raised higher than the other, or, otherwise stated, the rails adjusted to proper grade relative to each other. Sometimes one rail is positioned at a higher grade level than the other such as on curves, for example. Gauging means for this positioning is also provided.

In addition to the standards or uprights the cross member 18 is supported and braced by the inclined frame members 19 which are extended above the cross member to brace and support the upwardly projecting brackets 20. Laterally spaced hydraulic jacks are provided, each comprising the plunger members 22 connected to the hangers 21 by means of the coupling pins 23 and the cylinder members 24 having pin and slot connections 25 and 26 to the elongated jack foot piece 27, which is common to both jacks and is adapted to supportedly engage the ballast between adjacent ties as illustrated in FIG. 4.

The pairs of rail engaging hooks 28 are pivotally mounted at 281 on hanger links which in the embodiment illustrated comprise the lower sections 29, upper sections 30, and the adjustable turn buckle sections 31. In the embodiment illustrated these hanger links are supportedly engaged with the coupling pins 23. The lower ends 32 of the hanger links are guidingly engaged with the guides 33 which locate the hook pivots 281 above the rails so that the rail engaging hooks may be swung into rail engaging position as shown in FIGS. 1 and 4, or retracted therefrom as shown in FIGS. 2 and 3. The rail engaging hooks are simultaneously operated but the jack rams are independently operated or controlled. The adjusting means for the rail engaging hooks comprise the angled levers 34 which are pivoted at 35 on the frame supported v.bracltets 36. The outer arms of these levers are con- 3 nected to the hooks by means of the links 37 and their inner arms are connected by the links 38 and 39 to the arms 49 on the rockshaft 41 which also has an arm 42 connected to the plunger 43 of the hydraulic cylinder 44.

The operating connections for these cylinders 24 and 41 'will be described later.

The tie engaging hooks 45 are pivotally mounted at 46'on the cross bar 47 on which a pair of oppositely facing'hydraulic units 48 are mounted, the plunger rods :49 of which are connected by the links 50to the upwardly projecting ears of the hooks 45 by the-pivots 51. The

cross bar 47 is provided with insulating rail engaging bumpers 52 adapted to engage the topof the'rails when the cross bar is in its lowered position. The crossbar 'is seated upon the rails by-means of hydraul-icunits, the

cylinders 53 of which are pivoted at 54cm the underside of the cross head 18. The plungers 55 of these hydraulic units are connected by the links 56 to the cross head 47 through the couplings 57. Pins 58 are provided-for securingthe links 56 to the ears or brackets 59 only while the machine is being transported.

An important feature of the applicanfis invention is the adjustable gauging means which may be-set so that the operator can know when the rails have been lifted to a predetermined point or grade level.

This gauging means includes the sight gauge or level designated generally by the numeral 60 and positioned in front of the seat of the operator, see FIG. 1. This sightgauge is operatively associated with the track engaging members 61.

The gauge rods 62 are guidingly supported by brackets V The rail contacting gauges '61' areprovided with sight gauges 83 which are connected by the cross bar 84. These sight gauges are adapted to be used in a well known manner.

The rods 62 are provided with calipered or scaled 'gauging indicia members 85 having gauging indicia 86 thereon, see FIG. 3. These members 85 are swingably connected to the upper ends of the rods 62 by the couplings 88. The members 85 are provided with racks with which the adjusting members designated generally by the numeral 87 carried by the gauge bar coact.

"This arrangement enables theproper positioningof the si'g'ht gauge or "level relative to the track engagingfmembers so that it will come to a horizontal readable position *when the tracks have been raised to the proper 'height and in pi'edetermined relation to each other.

The rail engaging members 61 are provided withinsulating rail contacts 89 and it is desired to point out that all rail engaging parts including the wheels arede sirably insulated so that the use of the-machine on a partciular section of track will not interfere with the'elec- 'trical signal system that may be associated with the track.

With this arrangement of parts the gaugingmeans properly set the machine is successively positioned in proper relation to the tie to be raised and tamped.

'It will be understood that while each tie is individually tamped-the raising of the rail above one tie to' p'rede- 'termined position will ordinarily raise adjacent ties, that 'is, if the spikes hold but the operator can determine at each setting of the machine whether the rails are in proper predetermined position and with thisarrangement of parts the rail engaging hooks are actuated to engage the rails, the tie engaging hooks actuated to engage the tie, and the jack actuated to raise the ties to the proper position indicated by the gauge unit and when that position has been reached the tamping unit is actuated to tamp the ballast of the tie with which the hooks are engaged.

The machine is. power driven and manipulated to engage 'the tie to be tamped and the brake set to hold'the carriage in that'position. As stated, the particular tampingunits illustrated'are those of the aforesaid Jackson "patent. These tamping units are mounted 'on the downwardlyprojecting-arms'on the'ends of the'cro'ss head 4 65, which are mounted for vertical sliding movement on the frame uprights or posts 17, the cross'head being provided with the pairs of guide rollers 66 engaging the uprights. This cross head is raised and lowered by the hydraulic rams designated generally by the numeral 67, one member of whichis connected :tothelaterally projecting arms on the brackets 20. oirthe cross head. In

the embodiment illustrated it is:the plungers:that are=.con nected to the cross headat 68.

The tamping unitscomprisepairs of blades 69 mounted on the supports 70, having vibrating motorsfil mounted thereon, the hangers'72'of'these s'upports'being swingably connected at 73 to. the laterally projecting arms 74 carriedby the links 75 which connect the corresponding ends of the elliptical springs 76 which in turn are, mounted on the ends of the arms64 of the cross. head. The straps 77 and 78 limit the-swinging movement of the tampers. Withthe rails and tiezelevated to the propenposition, the tamping units are lowered to tampfthe' ballast under and around the tie.

It will be understoodthat after atie has' beenproperly positioned andtamped, thetamper is'retracted, the tie and rail-engaging hooksreleased, the brakereleased, and

the carriage positioned so that the hooks .28 may be again engaged with the rails in the-.new position and the hooks 45---with -a succeeding; tie to-be-tampe'd: and the operationisrepeated.

When the machine isto be moved otherthantrom tie to tie, the tamper cross head is raised andsecured to the hanger=80 by meansoii-thecouplingipin 81. Bumpers 82 are provided'on the cross head 18. to limit theupward movement of the tamper cross head.

:In the embodiment illustrated the. rail and tie engaging hooksare automatically-actuatedwith the actuation of the jack, that is, when the jack is actuated to thrustingly engage thez-footapiece-thereof withlthe ballast, the

nail-and tie engaging hooks are automatically actuated to rail and tie. engaging position.

occasiontmayrequire.

In this' embodiment the cylinder members. of the hydraulic-jacks: 24-are connected -tosthe-lfootpiece and the plungers are "pivotally connected at 23 to the frame brackets-21, as has been described. The reason forthat arrangement of the jack parts is that in tamping, ballast may "be' 'thrown with considerable -force and. also .the; air filled with-grit or duct andifathe plungersawcre exposed they might become roughened or coatediwith: grit so 'as' to cause undue wear on the. jacks. .By connecting the cylinders ofthe jacksto the :foot piece that-condition is avoided.

The plungers 22 are provided with-suitable-heads. 221

at their--lowet longitudinally disposed endstsand have a passage 222 opening :belovw-the heads 221 and a passage 223 opening above the- --heads=:as is shown-inesection 'in FIG. 7. The coupling head of the plungeris connected to these passages and the -conduits-2241and 225 connect the plungers through the r valves 226- tothe pumpsl227. The valves 226 are manually operated. The pumps:227

a're powered through: a suitable-transmission '10 the engine 13 and are connected lotheaeservoir 15- bymeans or" "the conduits 92 and-93.

A valve? 94 is; provided for-the: hydraulic.connections for- 'thef'rail hookaand tie thookractuating; rams-48,- these conn'ectionsibeing shown at '95 "and 96-which connections are also connected to: the: raili ihookzwactuatingoram 4 4.

"Flie s't'em'=97-'of the'valve 94ris-provided with a roller 98 which is engaged bythe"upperiendof the-'jack cylinder when the jack cylinder is in retracted position as shown in FIG. 7. When the jack cylinder is forced downwardly the roller 98 slips ofi the cylinder and the valve opens. This opening of the valve as the jack is actuated powers the rams 44 and 48 and the rail engaging hooks and tie engaging hooks are actuated to engaged position and when the jack members are actuated to retracted position the rail hooks and the tie engaging hooks are automatically disengaged. The foot actuated valve 99 controls the rams for raising and lowering the cross bars 47. A foot pedal being shown at 100.

After the rail and tie have been raised to proper position the tamper unit is operated and this, as has been described, is raised and lowered by the hydraulic units or rams 67, the cylinders of which are, as stated, suspended from the brackets 20. The cylinders are provided with hydraulic connections 103 and 104 which in turn are connected to the valve 105 to the hydraulic source. This valve 105 is manually manipulated to lower and raise the tamper unit. The tamper cross head is desirably raised and lowered three or four times for each tie.

It should be noted that the tamper unit illustrated is not designed to completely tamp the ballast but is designed to tamp the ballast to properly support the ties and rails for final or complete tamping. New ties may be inserted if desired and properly supported for tamping.

The carriage of the embodiment illustrated is hydraulically driven and means include the hydraulic motor 106 which is controlled by the valve 107.

In order to reduce the return pressure on the jacks pressure release valves 108 are provided in the return conduits 109. In the embodiment illustrated the hydraulic pump 14 is provided in addition to the pump 227 and is hydraulically connected to the reservoir 15 and to the actuating rams described.

The gauge members 61 are automatically actuated to and from rail engaging position by the actuating of the rail engaging hooks to and from engaging position, the track gauge members being connected by the chains 112 to the hook actuating levers 34, see FIG. 6. This further adds to the automatic operation of the device.

It should be pointed out that the main functional purpose of the release valves 108 in the hydraulic jack operating mechanism is that of varying upthrust as compared to the down thrust power of the jacks. The down thrust on the foot piece or jack member desirably greatly exceeds the upthrust for the reason that if the jack foot should happen to engage a rail or some other part it would break or distort some portion of the machine. Therefore, the uplift pressure or power is desirably reduced.

With this relation of parts after the machine ha been properly positioned relative to a tie, the gauge having been set, the first step is to operate the foot valve control 100. This automatically opens the valve supplying the jack elements and through the connection described the rail clamping and tie hooks are automatically engaged. The operator then manipulates the valves 226 until the rails and ties have been brought to the proper level which is indicated by the sight bubble 80 of the level. The tamper unit is then manipulated as described until the tie has been tamped to hold the rails at the predetermined grade. The jack is then retracted which automatically releases the rail and tie engaging hooks and the machine is moved to the next tie and the operation repeated.

The machine is of large capacity and may be very easily operated. Means are commonly provided for facilitating the removal of the machine from the track and replacement thereon but such means is not illustrated as it forms no part of this invention.

The invention has been illustrated and described in a highly practical embodiment thereof. I have not attempted to illustrate or describe certain modifications which might be desirable for certain uses as it is believed that '6 this disclosure will enable those skilled in the art to embody or adapt the invention as may be desired.
