new and useful Tie-Handling Apparatus, of

which the following is a specificatlon.

f This invention relates to apparatus especially designed for use in removing old ties and replacing them with new ones, without disturbing the rails resting on the ties.

Another object is to employ mechanism of this type mounted on a hand car or the like which can be brought to position above the ties to be removed, said car carrying mechanism which will operate to pull a tie laterally from beneath the rails and, if desired, at the same time direct a new tie into the space under the rails thus produced.

A further object is to employ means for clearing out the space below the rails so that there will be no obstructions interfering with the admission of a new tieto said space.

With the foregoing and other objects'in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can-be made within the scope of what is claimed, without departing-from the spirit of the invention.

ferred form'of the invention has been shown.

In said drawings :Figure l is a bottom plan view of the mechanism constituting the present invention, the cranes being shown extended in opposite directions from the body. Fig. 2 is a side elevation, one of the cranes being extended laterally and shown in section while the other crane is extended upwardly and has its upper portion removed. Fig." 3 is a section on line A-B Fig. 1, one of the cranes being shown extended laterally and .the other being 'view of a portion of a tie having the shoe attached thereto and showing the means provided for connecting the shoe to the tie and for connecting the tie to the handling mechanlsm. Fig. 7 'is a perspective view showing portions of two ties detachably connected. Fig-8 is a section on line CD Fig. 7.

Referring to the figures by characters of reference 1 designates a hand car structure adapted to travel along a track to be repaired and secured to the sides of this structure between the supporting wheels 2 are depending side frames 3 connected at their front and rear ends by cross bars 4. Mounted on these cross bars are bearing members 5 in which are journaled the ends of a shaft I 6 which is provided, at its center, with opposed clutch members 7 and 8 and a sprocket 9, the sprocket receivin motion through a chaln 10 from a sprociet 11 driven by a motor 12 on the platform of the car struc- I ture. Obviously any other means may be used to drive the shaft 6.

Looselymounted on shaft 6 between clutch member 8 and one end portion of the shaft is a spool or windlass 13 having-a clutch member 14 shiftable into and out of engage-f 'vided with a 'clhtch member 17 shiftable into and out of engagement with the clutch member 7. Any means desired may be provided for shifting these clutch members 14 and 17. For example, independently operated levers 18 may be pivotally mounted under the car.

structure, said .evers being connected to the respective clutch members 14 and '17 as shown particularly in Fig. 1. Thus by shifting either lever in one direction, the spool connected thereto will be coupled to the shaft v 6'whereas whensaid lever is. shifted in the Pivotally mounted upon one of the side frames 3 is acrane jib 19 mounted to swing upwardly and downwardly and preferably opposite direction the spool will be un-- coupled from the shaft.

tapering toward its outer or free end. This jib has a brace 20 pivotally connected to its outer end portion and said brace is adapted,

when the jib is extended laterally from the car structure, to engage a retaining stud or 'clined position as shown particularly in Fig.

3. WVhen the jib is in its raised position, as shown at the left of Fig. 3, it will be held in such position by a hook 22 or the like engaging the projection 21. Adjustably connected to the outer end portion of the jib is a stem. 23 to one end of which. is pivotally attached a base plate 24. \Vhen the jib is extended laterally beyond the car structure, this base plate is adapted to engage the surface of the ground sothat the stem 23 cooperating with the brace 20 will prevent the car structure from tilting while in use. Another crane jib 25 is mounted upon the other side frame 3 and is similarly provided with a brace 20, a hook 22, a stem 23 and a base plate 24-. These two jibs are not disposed directly opposite each other but, as shown in Fig. 1, one of them is arranged in advance of the other.

Pivotally connected to each of the frames 3 is a latch bar 26. These bars are arranged directly opposite the jibs and are extended toward the respective jibs. Each bar is adapted to rest upon one of the rails upon which the car is mounted and has a stop lug 27 for engaging the inner side of the rail. Thus when the jib at the right side of the car is extended laterally, the latch bar 26 cohnectedto the opposite side of the car will rest upon the right hand rail and prevent the car from pulling toward the right. At the same time the latch bar which is pivotally connected to the right side of the car will engage the left rail and prevent the car from thrusting toward the left. This will be obvious by referring to Fig. 3. -The latch bars can be adjustably supported by rods 28 pivotally connected to them and extending through brackets 29 on which the bearings 5 are mounted. By pulling upwardly on the rods and securing them in any suitable manner, the latch bars will be supported out of engagement-with the rails. In the drawings, the rails have been indicated at R.

a J ournaled within the outer' end portion of each of the jibs is a double sheave -or pulley 30 engaging a cable 31 one end of which is fastened to a pulley block 32. This cable 1s extended around the pulley 33 and the pulley 30 and is secured at its other end to one of thespools l3 and 16. In other words, the cable 31 carried by one of the jibs is attached to spool 13, while the cable carried bythe other jib is attached to spool 16.

Connected to each block 32 in desired manner, as by means of chains .34 are tongs 35 adapted to embrace and bite into opposed faces of a tie T as shown particularly in Figs. 3 and 6. v 4

Should it be desired to remove an. old'tie from under the rails and, at the same time, to replace it with a new tie, the car'- is brought to position above the point where the change is to be made and the latch bars 26 are lowered into engagement with the rails. One of the jibs is then lowered to the position shown in Fig. 3 and the tongs 35 carried by said jib are placed in engagement with one end of the old tie T. A new tie indicated at'T is placed with one end against one end ofthe old tie T and is fastened thereto by means of a coupling staple such as shown at S. After the spikes connecting the advancing end of the new tie between the upstanding flanges 36 of a clearing shoe 37 the front edge of which is preferably sharpened and. shaped to form a lip, as shown at 38. Slots 39 are formed in the flanges 36; The points of the tongs are in serted through the slots and into engagement with the new tie as shown in Fig. 6 so that when said tie is drawn longitudinally, the shoe 37 will be held thereto and will clear the path of the newtie so that it will move to position without encountering any obstruction. By employing the structure described it becomes unnecessary to provide any special means for attaching the shoe to the tie. Instead the tongs employed for coupling the tieto the pulling mechanism also serve'as a means for attachingthe shoe to the tie. Obviously when the mechanism is not in. use, both of the jibs can be held in upstanding position and the latch bars 26 will also be raised so that the car can thus be transported readily from place to place.

It is to be understood that where the tongs are tobe used in connection with the shoe 37 for the purpose of placing a new tie in position, it is advisable to connect the chains 34 of the tongs to one end of a rod 40 which is of sufiicien't' length to reach under the two rails of the track before the operation. of drawing the new tie into position is com.- menced.

What is claimed is 1. Tie handling apparatus including a car structure, a jib connected to one side of said structure and adapted toswing upwardly and downwardly relative thereto, means adjustably connected-to and carried by the jib for engaging the ground. and supporting'the laterally extended or active position, a block and tackle carried by the jib, tie engaging .tongs connected to the block and tackle, and

power driven means upon the car structure :Eor actuating the block and tackle to pull a tie engaged by the tongs out of position under the car.

2. Tie handling apparatus including a car structure, a jib connected to one side thereof and adapted to swing upwardly and downwardly, tongs connected to the jib, power actuated means carried by the jib for pulling the tongs, and a tie receiving shoe having tong receiving openings therein at the sides thereof, said tongs constituting means for gripping a tie and for holding the shoe upon the gripped tie.

In testimony that I claim the foregoing as 15 my own, I have hereto aifixed my signature in the presence of two Witnesses.
