To allwhom may: concern:

Be it known that I, GEORGE J OSEPH BURY, of the city of Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Machines for Removing and Replacing Track-Ties, of which the following is the specification.

My invention relates to a machine for removing-and replacing track ties, and the object of the invention 1s to provide a machine of the above class which can be quickly and effectively operated when in use, the device being carried, on what is commonly called, a flat car.

It consists essentially in a suitably supported platform, pivoted gripping jaws located beneath the platform and movable toward and away from the same, means for controlling the movement of the jaws, a swingable arm located tothe side of the platform, a reciprocating rod carried by the arm, means for reciprocating the rod and means for raising or lowering the arm, the parts being arranged and constructed as hereinafter more particularly described.

Figure 1 is an end elevation of the device showing it in the inoperative and then in the operative position, the latter position being dotted. Fig. 2 is a plan view of the parts appearing beneath the platform, the arm being down. Fig. 3 is a plan view of the platform and parts located thereon. Fig. 4 is an enlarged detail cross sectional view through the arm and cylinder carried thereby, the section being taken in the plane denoted by the line X X, Fig. 2. Fig. 5 is an enlarged detailed side elevation of part of the apparatus employed for raising or lowering the arm. Fig. 6 is an enlarged detailed plan View of the arm located at the side of the platform and the head of the cylinder carried thereby.

, In the drawings like characters of reference indicate corresponding parts in each figure. j

1 represents a platform such as the ordinary platform of a box car, which platform is supported above the rails 2 and 3 by suitable car trucks, (not shown) of the ordinary form. The rails 2 and 3 are supported on the ties or sleepers 4.

5 is a cross shaft mounted in suitable bearings formed in the platform beams 6. The shaft carries arms 7 and 8 which are connected through sets of links 9 and 10 with end blocks 11 which space and connect opposing horizontally directed bars 12. A lever 13 .passes upwardly from the shaft 5 and is connected by a pin to a reciprocatin piston rod-14 passing into a cylinder 15 and supplied with a piston 16. The cylinder is fitted with inlet and outlet ports 17 and 18 of any suitable design so that air or steam can be led into and away from the cylinder to reciprocate the piston backwardly and forwardly within the cylinder as desired. The bars '12 carry pairs of gripping jaws 19 and 20 held in place by straps 21 and pins 22 and connected at their upper ends by links 23 and 2 4 to common rocker arms 25 and 26, said. arms being swung on pins 27 carried by standards 28 extending upwardly from the bars. The approaching ends of the rocker arms are connected to the upper end of the piston rod 29 which operates in the cylinder 30, which cylinder is supplied with inlet and outlet ports to allow of the admission of steam or air as the case may be.

' 31 is an arm formed from channel iron members 32 and 33 swingably secured at their inner ends bymeans of pins 34 to the extending ends 35 of the bars 12. Stops 36 are located in the channel iron pieces toward the outer ends thereof and are bolted through such pieces to plates 37, which plates are united by a cross rod 38 which prevents the ends of the channel iron pieces from spreading.

39 and 40 are similar bars slidable within the channel iron pieces and having their inner ends turned backwardly on themselves at 41 so as to engage with the stop pieces and prevent the bars from being withdrawn endwise from the arm 31. A cylinder 42 is permanently secured to the bars 39 and 40 and is supplied with a piston rod 42 and piston 43. The piston rod carries a head 44 of angle'iron cross section, which head is adapted to receive and support the end of the tie as will be better understood hereinafter. Inlet and outlet ports 45 and 46 are suppliedat the ends of the latter cylinder to allow steam or air to be led to or away from the cylinder so that the piston can be reciprocated as desired backwardly or forwardly.

47 is a post carried by the platform and suitably reinforced by braces 48 and 49. The post carries pulleys 50 and 51 located at right angles toeach other, and a cable 52 passes from the cross rod 38 over the pulley 50 around the pulley 51 to a pulley 53 can i-ied by the extending end of the piston rod 5i where it returns to the base of the postand is anchored at 55. The piston rod 54 is supplied with a piston 56 which operates in a cylinder 57 in turn supplied with inlet and outlet ports which allow steam or air to pass into or out of said cylinder as desired to reciprocate the piston red.

It is to be understood of course that the flat-Bear is drawn along the track by the usual railroad engine and that the steam or air used in the cylinders is supplied from the engine. I have not considered it necessary to give a detailed description of this particular part nor of the particular manner in which the pipe lines are connected to the respective cylinders as such connections are very common and could be fitted very readily by any ordinary mechanic.

When the device is used the car is moved along the track to the point where the tie that is to be removed is located.v Steam or air is then admitted to the cylinder 15 to draw the piston rod so as to swing the arms 9 and 10 downwardly. This lowers the gripping jaws so that they grip the rails of the track immediately {at the sides of the tie that is to be removed, and the steam or air is then led into the outer .end of the cylinder and the piston rod is forced in the 0pposite direction so that the bars carrying the gripping jaws are raised to release the rails from the tie. The piston rod 54 is next forced out to its outer position thereby allowing the arm 31 to swing downwardly to the horizontal position. The new tie to be placed beneath the track is inserted between the head 44 and the end of the old tie and air or steam is then forced into the outer end of the cylinder 42 causing the piston rod to pass toward the track. The new tie forces the old tie from beneath the track and takes its place. The piston is then drawn back into the cylinder by admitting steam to the opposite end thereof and the gripping jaws are released from the rail by allowing steam or air to pass into the cylinder 30 to draw the adjoining ends of the rocker arms 25 and 26 downwardly. The machine is then ready to advance to the next position where it is necessary to remove a tie and the operation is continued.

It might be found necessary owing to obstructions to raise the arm when the machine is removed from one place to another, and this is done simply by withdrawing the piston rod 54 which tightens up the cable 52 and raise the arm to the position shown in full lines in Fig. 1 of the drawings.
