2 Claims. (Cl. 254-144) This invention comprises novel and useful improve ments in a device for placing couplers, yokes and draft gears in place in draft pockets of railroad freight and passengerV cars and more particularly comprises a portable elevating means for lifting heavy equipment such as couplers, yokes, and draft gears into the draft pockets of railroad cars.

The principal object of this invention is yto provide a lifting deviceto facilitate the lifting and proper positioning of varous equipment of railway cars for insertingthe same into a desired location. v.

A further object of the invention is to provide a lifting apparatus which will facilitate the raising or lowering of heavy equipment of railway cars whereby the labor of applying or removing the same from their proper locations upon a railway car maybe considerably lessened and the time required may be greatly reduced.

A still further object of the invention is to provide an elevating device in accordance with the preceding objects which shall be particularly adapted for application to a railway car, and will employ the latter as a part of the framework of the lifting device.

Yet another object of the invention is to provide an apparatus in conformity with the above mentioned objects which may be readily connected to any available source of power for operating the same.

A still further important object of the invention is to provide an apparatus in conformity with the preceding objects in which there shall be employed a self-adjusting or self-centering supporting carriage for carrying the articles to be lifted. v Y

And a inal important object of the invention to be specifically enumerated herein reisdes in the provision of a lifting apparatus in conformity with the above mentioned objects which shall include an improved means for securely holding the same in vertically adjusted position.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, referenceV being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a front elevational view showing the manner in which the invention is utilized in connection with a railway car;

Figure 2 is a perspective view showing the supporting leg assemblies of the lift device together with the carriage and lifting mechanism of the same, the railway car and the article to be lifted by the device being omitted from this view;

In general, draft gears, couplers and their associated parts for freight and passenger cars are now placed in their draft pockets or removed therefromby hand, or with the use of jacks and blocks. In some instances, cranes and lift trucks are used for this work, but all of these methods involve a considerable amount of labor and time in order to handle the extremely heavy elements and manipulate the saine in the close quarters available, with a resultant very considerable cost. It is the vfundamental purpose of this invention to provide a relativelyY simple and inexpensive construction whereby such parts may be lifted and assembled; and rnay be disconnectedand Vlowered with relative ease, and at a considerable saving in time and labor. n

In carrying out the principles of this invention there is provided a supporting frame upon which a lifting mechanism is mounted. In order to simplify this construction, as will be apparent from Figure 1,'the railway car which is being serviced is utilized as a portion of the supporting frame of the lifting device. Thus, the railway car 10 of any desired type, shown blocked up from the railway tracks by jacks 12, constitutes a support for the upper end of a pair of legs or leg assemblies 1rd and 1.6.Y

The leg assemblies may be of any desired type, being preferably provided at the upper ends with curved extremities 18 which are adapted to engage any convenient portion of the railway car for properly positioning the upper ends of the leg assemblies which may rest upon the ground or oor. The leg assembly 14 comprises merely an anchoror abutment for the lifting device, while the other leg assembly 16 carries a winch assembly.

For this purpose, it will be seen that the leg assembly is provided with a transverse bar 19, rigidly secured thereto, and to which the ends of a pair of cables 20 are attached. The other leg assembly i6 has a power shaft 22 journaled thereon and this power shaft has fixed thereto a pair of winch drums 24 to which the other ends of the cables 20 are secured. As will now be seen, by rotating the shaft 22, the cables may be reeled in or letout as desired.

Power may be applied to the shaft 22 in any desired manner. Thus, the shaft may be provided with a pulley 26, as shown in Figure 1, and which may be driven as by belt 28 from any suitable source of power. Referring again to Figs. 1 and 2, it will be seen that a carriage 30 is mounted on the cables 2i) for movement therealong and for lifting thereby as the cables are wound upon the winch drums. Preferably this carriage comprises a pair of side rails 32 from which depend pairs'of Z-shaped A Patented Mar. 1 5, 196.()l

along the length of the cables will center itself at the mid portion of the same. Consequently, an article to be lifted by the carriage, as for example a coupler and draft assembly indicated in dotted lines in Fig. 1 by the numeral 40 may be raised or lowered, and may be inserted into or removed from the draft pocket 42 of the railway car.

In order to maintain the carriage and the article carried thereby at any desired elevation, there is provided a brake mechanism cooperating with the winch assembly. Re erring to Figs. 3-5, it will be seen that the shaft 22 has fixed thereto, a conventional brake drum 44 and a brake.

band or brake shoe 46 surrounds this drum,ebeing carried as by a bracket 48 secured to-the leg assembly 16. The ends of the brake shoe are yieldingly ,urged upon or into brake releasing position as by a spring 50 and a bolt-52 secured to one 'end of thebrake shoe and beingtslidably modiicationsandV changes will readily occur tothose received withinv an aperture' in a bracket 54 attached to 1 theother end of the brake shoe `provides means for contractingthe brake shoe upon the brake drum and thusV on the lever arm has pivoted thereto a link 62 which in l turn is pivoted as at 64 to a bell crank member 66 having its mid-portion pivoted Yas at V68 to a link 76 which in turn is pivoted as at 72 to a supporting bracket'74 carried by the leg assembly 16. The other end of the bell crank is engaged with the extremity of the bolt 52 whereby movement of the lever will actuate the assembly and thus actuate the brake to lock the winch drums in selected position. t

As shown in Fig. 9, either of theA leg assemblies such as that indicated at 14 may be provided at its lower end with a detachable and adjustable extension. The latter may consist of a U-shaped frame 80 having a pair of upstanding leg members 82 and at their lower ends having a cross-connecting member 84. Bymeans of bolts 86, the legs 82 may be attached'to the sides of the leg assembly 14 and thus provide an extension for the same.

It will be observed that by this invention the lifting device will be quickly applied to or removed from arrailway car; and will enable the application of 'power Vfrom any suitable source to raise or lower the articles being handled by the device. The labor and operations of servicing such heavy equipment of railway cars as couplers,

draft gear and their associated parts is thus greatly t simplied.

The foregoing is considered as illusrative only of the principles of the invention. Further, since numerous skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
