SPECIFICATION forming part of Letters Patent No. 507,29B,clated October 24, 1898.

Applioation filed May 12, 1893- Serial No. 474,009 (lilo model.)

.To all whom it may concern:

Be it known that I, JAMES TIMMS, residing at Columbus, in the county of Franklin and make and use the same.

. My invention relates to an improvement in car couplings and more particularly to draft attachments for the coupling-the invention being especially adaptable for use on alocomotive engine tank.

The object of the invention is to construct a draft attachment for a car couplingin such by the motion of the manner thatthe knuckle of the coupling will be relieved of th'egrinding movement caused car to which the coupling is attached.

-A further object isto attach a coupling in such manner that it can have a vertical and a lateral movement when in use:

With these objects in view the invention consists in certain novel-features of construction and combinations and arrangements of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings: Figure 1 is a plan view illustrating my improvements; Fig. 2 isa sectional View. Figs. 3 and 4 are detail views. Fig. 5 is a view of a modification. 4

A represents the end sill, and B a portion of the platform of a car or locomotive-engine tank. The end sill A is made with parallel, elongated openings 6, b,*with which elongated slots 0, c, in a face plate 0 are adapted to align,

saidface plate being secured to the front face of the sill by means of bolts passing through the sill. At three sides of each slot 0, flanges d, dproject from theface plate C, and between the ends of the flanges d, flanges e, e, project from said face plate for a purpose which will hereinafter appear. Passing through the slots 0 and openings b are plates D, the front ends of which are secured to the coupler head E. The plates D are of a thickness less than the depths of the slots c and openings 1) and areof a width less than the length of said slots and openings, so that said plates D can have a lateral and a vertical movement insaid slots oropening's. The rear .ends of the plates D are connected bya plate D, secured thereto by means of bolts f, passing through flanges projecting from said plate D and theplates'D, thus producing-a yoke. In order to maintain the plates D and the coupler head E carried thereby, in a normally horizontal position, a bar E is made to project downwardly from the platform B, in rear of the sill A, and at its lower end is preferably provided with a plate g, against which the upper plate D is adapted to bear. A semic'enter against the coupler head and at its ends against the'face plate 0, being limited the flanges e,-said semi-elliptical spring being adapted to act as a butter.

"imit-y to the rear ends thereof, is a spring G, of a length sufficient to project at its ends beyondfthe edges of said plates D, and provided with lugs h adapted to bear against the edges er relation thereto.- The rear-face of the plate flanges i adapted tobear on the end plate l) and produce arocking bearing for the spring plate G on said end plate D". ,7

A plate'H is located between theplates D and adapted to bear against the rear face of e sill A, said plate H being retained in proper 'jectthere'froin parallel'with the edges of the plates D. Located between the spring plate G and the plate H, are coiled springs I and within the coiled springs I, smaller coiled springs I are located and adapted tobear at their respective ends against said plates and maintained in properposition by means of bosses k, k projecting therefrom.

From the construction and 'arrangementof parts above set forth it will be seen that the spring F will act as a buffer as above explained, and that the springsl, 1?, will serve to cushion the pullingaction on the coupling. It will also be seen that the coupling head will be permitted to have a vertical and a lateral movement when inuse, thus preventing the grinding movement upon the inner face of the knuckle of the coupling and also Located between the plates. D, D, in prox elliptical spring E is adapted to'bear at its in its movement on said plate by means of of said plates and thus be maintained in prop- .G' is provided with a series of curved ribs or position by means of lugs j adapted to pro 1 ioo allowing the coupling to be held intact, which would not be the case were the coupling to be bolted directly to the sill. It will also-be seen that the pulling action of the coupling will be brought to bear on the rear face of the sill. V

Instead of making the plates D, D and D' in separate parts, they may be all made in .one piece as shown inFig. 5.

My improvements are very simple in construction, cheap toma'nufactu-re and efiectual in every respect, in the performance of their functions.

Slight changes might be made in the details of construction of myinvention without departing from the spirit thereof or limiting its scope and hence I do not wish to limit myself to the precise construction and arrangement of parts herein set forth, but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a sill havingopenings therein, of a drawhead having rearwardly extending plates extending loosely through the openings, said plates of less width and thickness than the openings and capable of sliding or being vibrated therein, means for connecting the plates together at or near the rear ends, and springs inter posed between the sill and connecting means between the plates, substantially as set forth.

2. The combination with a sill having open-.

ings therein, of a drawhead having rea'rwardly extending plates which pass freely through the openings in the sill and are 0onnected together at or near tlfeir rear ends, said plates of less width and thickness than the openings, and springs located forward and rearward of the sill and bearing respectively against the drawhead and connection be tween the plates, substantially as set forth.

3. The combination with a sill and acoupling, of a yoke connected to said coupling and passing through openings in the sill, springs located between the end of said yoke and the rear face'of the sill, and a spring located between the front face of the sill and the coupling, substantially as set forth.

a. The combination with a sill anda coupling, of a-yoke secured to said coupling and passing through openings in the sill, said openings in the sill being longer than the width of the plates of said yoke and wider than the thickness of said plates, substantially as set forth.

5. The combination with a sill and a coupling, said sill having openings therein, of a plate secured to the front face of said sill andv -having slots in alignment with the openings in the sill, plates secured to said coupling and passing through said openings and slots slots, an end plate connecting said first mentioned plates, springs located between the end plate and sill, and a spring adapted to bear on the coupling and the plate on the front face of the sill, substantially as set forth.

6. The combination with a sill and a coupling, of a yoke secured to said coupling and passing through said sill and adapted tohave a lateral-mogement, a plate located in said yoke and adapted to have a rocking movement on-the end of the yoke, and .a connection between said plate and the sill, substantially as set forth.
