UNITED STATES JOHN JACOB WOLF, or noonron, NEW JERSEY. I

SHIFTING APPARATUS.

Application filed November-15, 1921.

To all whom it may concern.

Be it known that 1, JOHN J. WoLr, a citi-' zen of the United States, and a resident of Boonton, in the county of Morris and State of New Jersey, have invented new and useful Improvements in Shifting Apparatus, of which the following is a full, clear; and exact description.

This invention relates to improvements in shifting apparatus primarily designed for shifting railway cars.

The general object of the invention is the provision of eflicient and durable apparatus for the shifting of loads which may be provided in conjunction with roads of all kinds without interfering with traffic.

A further object is the provision of apparatus which may be used for removing a car or other load from a line of traffic, making the work of shifting the cars, so as to place the car or load at the unloading platform, unnecessary.

This object is accomplished by providing means that maybe projected under the car or load and associated with means for lifting the latter from its support and then moved in a horizontal plane carrying the car or load therewith into position at the unloading platform.

These and other objects of the invention will be more clearly understood from the following detailed description and accompanying drawings, in which Figure 1 is atop plan view of the apparatus;

Figure 2 is a side elevation of the apparatus;

Figure 3 is a section along the line 3-3 of Figure 2.

Referring to the abovementioned drawings, the shifting apparatus is shown in conjunction with a roller track 10 and a loading and unloading platform 11. The apparatus consists of a plurality of runways 12 in which the beams 13 are mounted. These runways 12 are provided with rollers 14 on which the beams 13 travel. These beams are preferably made from anumber of I-beams fixed together by means of plates. Located on the lower flange of each beam is a rack 15 with which the. pinions 16 mounted on the shaft 17 mesh. A pulley 18 is fixed to the shaft 17 and driven by the electric motor 19 which is connected thereto through a pulley 20 carried on the motor shaft and a belt 21. A source of elec- Serial No. 515,232.

trical energy is connected to the motor by means of the line 22, and the supply of cur rent to the motor. is controlled by a switch 23. The apparatus so far described is located underneath the loading or unloading platform. Openings 24 are provided in the front wall of the platform and the beams 13 may be projected throu h these openings.

Located beneath the rai way track are a plurality of jacks 25; a 'ack bein provided for each beam. A plurality of rollers'50 are carried by each jack 25 to allow the beams.

13 to be drawn across the top of the jack.

Mounted on each jack shaft is a gear26,.

and a chain belt 27 is provided to connect the said gears so that they willall be driven at the same speed. Ashaft 28 which carries a gear 29 and a bevel gear 30 is mounted between a pair of jacks in such a position that the gear 29 engages the chain belt- 27.

The shaft 28 is driven by means of a motor 31 through a shaft 32 and a bevel gear 33 carried thereby and meshing with the -'bevel gear 30. The motor 31 is connected to the line 22 by means of a switch 49 located beneath the platform 11. A wheel 34 carried by a shaft 35 is located between the runs of the chain belt 27 and in alinement with the gear 29 so as to cause a positive engagement between the chain belt and said gear.

Associated with each beam 13 is a supporting post 36. These posts are carried by foundations 37 mounted between the railway track and the platform. Each post is loosely connected to the beam with which it is associated by means of a hook 38 so that 7 as the beam is moved u or down the'post will also be moved. Rol ers 39 are mounted on the posts 36 and interposed between the posts and beams. Guides 40are carried by the beams to retain them in engagement with the rollers 39. Blocks 41 supported on the foundations 37 have openings 42 therethrough, in which the posts. 36 slide. Slots 43 are provided in each post and springoontrolled bolts 44 slidably'mounted in the blocks 41 engage in the slots to retain the posts in the different positions to which they are moved. Solenoids 45 are provided in conjunction with each bolt and are energized by means of a. switch 46 which serves to connect them to the line 22. These sole- A car comprising a'car box 47 and atruck 48 is fshovv n positioned over'ithe beams 13 and 'jaeks'25.

The operation of this device is as follows:

When it is desired Ito move aicar from a line of cars at a particular loading platform, the car is moved to position in front of the loading platform. The motor 19 is then operated by means of svvitc'h23'to project the beams ,13. outward over the jacks 25 and ,underneath theIearbEiX 47, The switch 46 is then closed, energizing the solenoids '45 to v'vithdraw' thelbelts lt from the slots l3 in the;posts.36. "Then theisvvitch49is closed to set thefmotorf31 in operation. The motor 31fsoper'ates-the jacksj25'through aseries of gears and Qchainbelt, raising the beams 15 .in'to en agement with ithe car truck 4:8, lifting Yitc' earlof the track 10. Switch d6 .is then ppened, releasing the spring-controlled boltsht l which @enga'gejin the slots 43 serving toflock the posts 36 in their raised positions, atthe same time. the switch .49 is opened or reversed thus:stopping the operation of the acks orirevers ing .the direction of operation so .thatthe jacks are returned to their %nor- :mal position,"sho,Wn.in Figure 2, .SWitchQES is then operated tofdraW .the beams 13 in- Ward, .carryingosthe fear 130x47 into position beside the platform. 'flhelineof cars may then be :moved in either direction to posiitionlanothercar.
