for lifting or moving the rails of a track-on which the lifting device is itself mounted.-

Another purpose is the provision of improved control means for controlling the lifting movement.

Another purpose is the provision of ready means fortilting the track as it is lifted, or for track.

Other purposes will appear from time to time in the course of the specification and claims.

The invention is illustrated more or less diathe two rails of the same grammatically in the accompanying drawings wherein: a

Fig. 1 is an end elevation of the device taken along the axis of the track;

Fig. 2 is a side elevation of the structure shown in Fig. l; H

,Fig. 3 is a plan view of the frame structure partially assembled;

Fig. 4 is a section on the line 4-4 of Fig. 1;

Fig. 5 is a-section on the line 5-5 of Fig. 2;

Fig. 6 is a section on the line 6-6 of Fig. and

Fig. 7 is Fig. 6.

Like parts are indicated by like symbols throughout the specification and drawings.

Referringto the drawings, I generally indi cates the road bed. Ties to which the rails are secured are indicated at 2, for example in Figs. 2 and6. Sindicates a tie, as in Fig. 6, to which the rails are not secured. The-rails are indicated as at 4 and may be secured to the ties by any suitable means, for example by the spikes 5.

A generally indicates a base frame which includes longitudinally extending channel members 6, which may be connected adjacent their central portions bya pair of transversely extending channels I and are connected at their ends by tubes 8, the ends of which may be connected to the ends of the members 6 for example, by plates 9. v I 7,

Wheels Ill are journaled at each end of the pipes 8, and any suitable ball bearings-and in: sulating connections may be employed, as indicated diagrammatically at H.

Upwardly extending from the frame A is an upright frame structure generally indicated as B. Extending upwardly from the cross channels I at each end thereof, but somewhat within the an enlarged section of a portion of extending square tubes l5.

12, which are connected at their upper ends to transversely extending square bars l3, which extend in parallel across the top of the device, as shown at the top of Fig. 6.. Thestructure so formed is braced by angular members -14, throughthe intermediary of short longitudinally Additional angular cross-members I5a are welded to the bars l3. The structural members l4 extend downwardly and outwardly and are secured adjacent the ends of the member 6 as by plates l6. The transverse members I and I3 are connected by crossed braces l1, the lower ends of whichmay be secured as to additional plates l8. Secured to the members 5 are sleeves 20, 2|, vertically out of alignment, as shown in Fig. 6, and carrying telescoping handle members 22, 23, the parts being proportioned so that the handlebars can be telescoped without interfering with each other. The sleeves 28,v 2|. may be secured to each other .or otherwise suitably braced.

The structure above described provides in effect a thoroughly braced .and .powerfulframe, which has wheels at each side wherebyit rides along the rails of a track. It carries thrust means and a power plant, below described, whereby the frame and with it the rails of the track on. which it rides maybe lifted upwardly from the road bed.

Any suitable power plant may be employed, but illustrated generally is any suitable motor 25, the details of which form no part of the present invention. The motor may be mounted on straps or plates 26 spanning the transversely extending channels 1. The motor is provided with a drive shaft 21 and a. double sprocket 28, each sprocket driving one or more chains 29, 30. The chains 29, 30 pass about sprockets 3|, of which there are pairs at each side of the frame, which drive pumps generally indicated as 32, the details of which of themselves form no part of the present invention. The drive above referred to may be covered by a housing I0 0.

The pump structures are mounted on any suitable platforms 33, which may be secured to or upon the cross members I. It will be understood that the above engine platform or the members 26 and the platform 33 and the pump structures may be adjusted transversely in relation to the frame A, whereby the parts may be properly assembled and adjusted. A fuel tank 34 for the longitudinal member Bare pairs of square tubes as motor 25 may be supported upon the transversely extending members I3, and a fluid tank 35 for the pump system may similarly be supported. The system of ducts for the pumps will not be described in detail, as the details of the pumps form no part of the present invention.

Since the function of the present device is to raise the rails from the road bed, means are provided for locking the frame to the rails or the rails to the frame, whereby when the frame A is raised by the mechanisms below described, the rails will also be lifted.

Mounted upon the members l3 are bearings 35, herein shown as open ended tubes mounted in plates 31. Extending between each pair of bearings 36, as shown in Fig. 6, is a shaft 38, carrying a head 39, which may if desired be loose on the shaft 38. Extending downwardly from the head 39 is a plunger 49, extendinginto the cylinder M, the cylinder passing through a split guide 42 mounted on the cross members I. It will be understood that the structures above described are in duplicate, there being a plunger and cylinder and guide for eachside of the frame.

At the bottom of the cylinder 4! is any suitable socket or lower end portion 431 44 is a road bed engaging shoe, slotted at each end, as at 45, to

receive pins 46, which pass through said slots 45 inan upwardly extending web portion 4'. of the shoe 44. It will be observed in Fig. 5 that the.

,web portion increases in height toward the centralportion of the shoe 44 in order to provide adequate reinforcement therefor. The pins 46 pass through lugs 43, which extend downwardly from and are herein shown as unitary with the bottom portions .43 ofthe cylinders 4|. Preferably the bottom portions of the members 48 are permitted to engage the upper surface of the shoe 44, whereby a direct thrust will be provided instead of. a shearing thrust on the pins 45.

It will be understoodthat by any suitable control means, .actuated for example by the hand levers 5&3, 51, the pumps 32 may be actuated or controlled in such fashion, that either or both of the cylinders 4! may be downwardly thrust. If both are simultaneously downwardly thrust, the frame will be raised bodily without tilting. If only one is downwardly thrust, one side of the frame will be raised. It will be understood that theoperator, by controlling thehandles 50, 5|, has the cylinders 4| in complete control so that he can raise both a certain distance and then raise one, or can raise one without raising the other, or he can lower one or both, or he can lock them in raised -or lowered position. Since the details of pump and pump control do not of themselves form part of the present invention, they will not be further described. Any suitable control rods, however, 52, are provided, extending for example to control valves or valve structures 53.

In order to raise th'erails with the frame when the frame A is lifted by the above described structure, rail engaging hooks iii] are provided, which are formed to extend beneath the top flange of the rails, as shown in Fig. 1. Each hook (it, as hown in Fig. 2, includes two separate but unitary hooks. Each hook or pair of hooks 613 is pivoted on a shaft Bl extending in parallel with and slightly inside of the rail top. Each such shaft is connected by one or more-rods 62 to the shaft 38, the members 62 thus acting as tension members for the lifting of the rails. The ends of the shafts 6| are guided at each side by guiding blocks 63, 64, which may be welded to the longitudinal and transverse frame members 6 and I. The rotation of the hooks and the movement to and from locking or rail lifting position may be controlled by any suitable hand lever 65, having a ball or weight 66, which normally holds it in the position of adjustment. The lever 65 is connected to a shaft 61 which extends through bearings in the members I and which controls oppositely extending lever arms 68 and 69, which in turn, through control rods 10, H, actuate the hook systems 60. Each hook has an outwardly extending arm 12, to which the outer end of the members 10 and H is pivoted as at 13.

It will be understood that any insulating means may be employed wherever necessary in the structure to prevent interference with any railroad signal system.

The operator preferably stands on a movable platform generally indicated as 14, which is roughly pivoted on a rod 15, by downwardly extending projections 16. The rod 15 extends to enlarged portions 16a of the plates l6, which are secured on the longitudinally extending frame members 6. These plates are provided with generally vertical slots 18, through which the ends of the shaft 15 extend. Springs 19, positioned in retainers 190. on the channel members 6, normally hold the shaft 15 in raised position. The ends of the shaft 15 carry brake shoes 8%. It will be understood, therefore, that when the operator stands upon the platform 14, his weight is sufficient to depress the shaft 15 and thus to depress the brake blocks or shoes 80 into gripping and operative engagement with a pair of the wheels l0, whereby longitudinal movement of the structure along the track is automatically prevented without the necessity of any attention being paid thereto.

The platform 14 also provides ready control means for the motor 25. In theposition in which the platform 14 is shown in Fig. 2, for example, the motor may be idling in low speed. When the operator stands on the platform 14, as above pointed out, his weight actuates the brakes. If the operator then throws his weight outwardly of the axis of the shaft 15, he causes the inner right-hand edge of the platform 14, referring to the position of the parts in Fig. 2, to rise, and this vertical movement of the inner end of the platform 14 may be employed in any suitable fashion to control the motor, for example by raising it to full speed. Any suitable means may be employed, for example a flexible connection, for example a spring 8|, which extends to any suitable governor or control handle 82 of the engine. Referring for example to Fig. 1, 82 indicates any suitable control handle, which may be used for example for controlling the throttle of an engine and thus varying the speed of the engine. The platform 14 is shown in Fig. 4 as having secured to tne inner end of it a spring 8|. This spring 81, as shown in Fig. 1, extends to the engine control handle 82. The user, when standing on the platform 14, can tilt the platform by shifting his weight about the axis provided by the shaft 15. Without removing his weight from the platform, and thus without releasing the brakes 80, the operator, by tilting forward-1y or backwardly on the platform, can cause the inner end of the platform to draw downwardly on the spring 8!, or can cause the inner end of the platform to tilt upwardly and release the tension of the spring '81. The spring 81 is indicated merely as an example of a usable connection, but any other suitable means for applying force may be employed, and what is essential is that the operator, by merely teetering the platform, may employ the platform as a means for controlling the engine speed. Since the details of the operation of the engine control do not of themselves form part of the present invention, they are not herein illustrated. The extent of the tilting movement of the inner end of the platform 14 is limited by the outwardly extending flanges of one of the channels I, as will be seen in Fig. 2.

It will be realized that, whereas a practical and operative device is described and illustrated, nevertheless many changes may be made in the size, shape, number and disposition of .parts. without departing from the spirit of the invention. It. is therefore wished that the description and drawings be taken as in a broad sense illustrative or diagrammatic, rather than as a limitation to the precise showing.

.The use and operation of the invention are as follows:

It frequently happens in track operations that it is advantageous or necessary to raise the rails from the road bed, for example in order to permit the removal of worn or rotted ties. It may also be important to lift some of the tieswhile failing to lift others. Also, a measure of lateral shifting may be necessary, or the track may be raised in order to increase the height of the road bed. Or this lifting of the road bed may take place on both sides or on one side, as where a curve is being lifted or built up.

As an example of the employment of the device, consider Fig. 6, in which the shoe 44 is shown as engaging the road bed, and the frame is in the elevated position. The rails 4 have been raised with the frame, it being understood that the hooks or clamps Ell are in the locking position in which they are shown in Fig. 1. Some of the ties 2 have been lifted, since they are still attached to the rails, whereas the tie 3 which was not so attached is now clear of the rail and can he slid out endwise. It will be understood, of course, that, if desired, for example if more than one are being removed, the shoe 44 may be superposed upon one of the removed or to be removed ties, which has the advantage of providing a good foundation for the lifting movement.

In the operation of the device, the operator stands on the platform 14, which has for one effect to actuate the brakes 8B and hold the structure as a whole against endwise movement. He can then speed up the motor by merely tilting the platform 14' rearwardly in such fashion as to raise its forward end. It is assumed, of course, that the control lever 65 has been moved into actuating position so that the hooks 89 are looked under the top flanges of the rails 4. Then the operator, by manipulating the levers 50 and controls the lifting effect of the pump driven by the motor 25. The details of this control do not form part of the present invention, but it will be understood that the user can simultaneously raise or lower both of the cylinders 4|, or he can raise and lower them differentially. Where the raising is differential, the shoe 44 being in engagement with the road bed or tie, stays in substantially horizontal position, and the frame as a whole is tilted. This bodily tilting of the frame exercises an unequal lifting movement on the two rails 4.

It will be observed that the cylinder 41 and the plunger 40 provide in effect a compression member for raising the frame and particularly th all) shafts 38. The hooks 60 and the rod 62 and their associated parts in turn provide a tension system for the lifting of the rails with the frame. Thus, all of the lifting is performed by a structure which includes only the plunger 40, the cylinder 4!, the rod 38, the tension member E2, the rod 6|, and the hook 60, together, of course, with the connections between the shoe 44 and the cylinder 4|. The slotted connection 45 between the shoe 44 and the pin 46 prevents any locking of the system when the above described tilting movement takes place.

It will be understood that for easy handling the telescoping handles 22 and 23 are provided. Four men may readily lift the entire device from the rails once the hooks 536 are moved into the full line position in which they are shown in Fig. 5. Or th device may be pushed along the rail once the shoe 44 is raised to the inoperative position in which it is shown in Fig. 5.
