To al?, whom it concern:

Be it known that I, HENRY F. POPE, of

Cleveland, inthe county of Cuyahogaand' State fof Ohio, have invented a new and useful Improvement in Radial-Draft Gears, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawings, forming part of this specification, in `which-l Figure 1 is a plan view partly in section; Fig. 2 is a vertical longitudinal section of the parts shown in Fig. l; Fig. 3 is a cross y section on the line III-III of Fig. 2; Fig.

` construction of the frame of the 4 is a sectional plan view showing the device as used with Master Car Buildersl coupler; and Fig. v5 is a sectional elevation of the same. f'

One purpose of my invention is to pro# vide a 'radial draft gear adapted to receive and hold car couplers having shanks of varions-sizes. Q As radial draft gears arenow constructed, they are provided -with couplers of special'design having a broad shank adapted to fit within the frame of the draft gear and to back and brace the lateral stopflange of' the coupler head lin such manner as to prevent their breaking, a'nd one of the purposes of my invention is to'provide a draft rig* ging of such character that it will receive not only the couplers of this construction, but ordinary couplers of the: Master Car Builders type having smaller Shanks.

Another purpose of my invention is to preferably construct the gear in such manner that the center line of the coupler shank will be held thereby in line with the center line of the draft rigging, and also preferablyinline with the center line of the pivotal support of the draft rigging and with the central plane of the sills, so that lthe draft gear will swing horizontally in the plane of the center line of the sills.

In the drawings, 2 represents the head of a coupler which is of special construction, having a broad shank 3, and lateral stops 4, 4, which project horizontally from the sides of the coupler so as 'to match with corresponding stops of an opposing coupler and to hold the couplers from buckling underlouling stresses. rlhe shank of this coupler is mounted within a frame, shown 1n section in Fig. 3, having top and bottom members 5, 6, and side members 7, 7, which are preferably anged and iitted together,l i as shown,

and are held by suitable securing cial coupler shown in Fig.

4'and bottom recesses 9, 9,

vbolts 8. The portion ofthis frame which incloses the coupler shank is shown in section in Figs. 1 and 3, and the portion there- 'of whichinclosesthe draft rigging back of the couplershank is shown in partial section in Fig. 1. -The portion of the frame which incloses the coupler shank is made interiorly of the cross sectional dimensions of the said shank and has on the top and bottom members 5, 6, internal recesses 9, 9, of the width of the corresponding portion of the shank of an Aordinary Master Car Builders coupler, so that if the coupler shownvin the drawings is removed from the frame, it can be replaced by such Master Car Builders coupler, which in that case will tit be-A tween the top and bottom members, and Will be held within the limiting walls offthe recesses 9, 9, as shown in Fig. 5.

10 is a filling block or buihng block, which' is seated within the frame at the rear end ofthe coupler shank and is backed by internal projecting flanges 11. This block is of-suitable strength to receive the bufiing stresses and to'transmit them through the flanges 11 to the frame. When the coupler shown in Figs. 1 and 2 is placed in the frame, the rear end of the coupler shank abuts against the face of the block 10, and is preferably of about the same cross sectional dimensions, so as to have contact with the entire surface' of the block. The

coupler shank is then rigidly secured to the fside members of the frame by lateral bolts or keys 12, which extend through the sides .of the frame and through horizontal holes When the spe- 1 is removed from the'lframe and replaced with an ordiin the shank .of the coupler.

pler'fits within theA frame and within the. top and abuts at its rear end against the illing'block 10, and

nary lMaster Car Builders coupler, as shown `in y-Figs.' 4 and 5, the shank 3 of this coubeing of less cross sectional dimensions than the surface of said block it does not bear upon the entire surface thereof. To receive such Master Car Builders-coupler, the top and bottom members of the frame are provided with vertical holes spaced to match the vertical rivet holes in the usual liner block of a Master Car Builders coupler, and when the coupler shank is putin position within the frame, it is held by vertical bolts 13 which pass through these holes in the frame and in th coupler shank.-

' on the yoke of a The bolts of both forms of the coupler are relieved of buing strains, for the reason that the coupler abuts against the bufiing block 10, and transmits its stresses thereto, and there are also preferably lips 14, formed' on the forward ends of the top and bottom members of the frame which engage'the forward surfaces of theliner blocks of the Mas-` ter Car Builders coupler, in order to relieve the bolts from stress during pulling, and thus to serve the functions of the usuallips coupler. As shown in Fig.

preferably provided" 15, which rests upon the coupler carryiron 16, and is secured to the frame of the draft gear by means of the forward bolts 8, which tie the bottom mem- 2, the frame is also with a wearing shoe 4desirable bers to the sidemembers.i Thiswearing-shoe has lugs 15 at its forward endv which fit within holes on the under side of the coupler shank, so as to hold the shoe to the shank during the lateral movements Vofthe coupler.- The purpose of the shoe is to relieve the shank from wear during lsuch lateral movement. Car Builders coupler is inserted 4in the l frame, it will also rest upon and will hold scribed.

the draft gear, -and an ordinary end of ing pulling,

the wearing-shoe in the same manner, except that the lugs 15 fit at the sides of theV coupler shank,` as shown in Fig. 4, instead of tting within vertical holes in the shank, as in the case of the special coupler above de- It will thus be seen that in case of' injury to the special coupler which is designed for it may be removed readily l Master Car Builders type substituted therefor withoutv special preparation. In such case, the shank of the Master Car Builders coupler Willt against the filling -block 10,) and -will transmit the stresses of buliing to the frame of the draft gear, and thence to the draft ri ging, thus relieving from strain the bolts w ich fasten the coupler shank to the frame.

The preferable arrangement of the draft rigging is shown in Figs. 1 and 2. The draft rigging is set within the frame and provided with suitable followers 17 `and 17 and the. yoke 18 of the draft rigging Ipasses in front of the front follower 17 and `extends back to the' vertical pivot pin 19, on`.which the draftgear is pivoted, so as to swing horizontally. The frame isl'slotted, as at 20, or otherwise so constructed that during buffing it will move over the pivot .19, and in so doing will fcrcethe front follower 17 against the spring rigging and will com ress the same, the rear follower' du'ring bu g-being held by and' abutting against the forward thebracket 21 on the car frame, which the pivot pin passes. @Durthe front follower 17 remains stationary, being held by the forward end of the yoke through When an ordinary Master I yin `modified uses, or tol modified' constructions 18, and the rear follower ,17 is drawn forward by its engagement with stops 22 on the side members ofthe draft gear frame. The frame is guided from the truck by means of alguiding connection, a

form of which, shown in the drawing, consists of an arm 23, which is slidingly cnnected at its forward end at 24 with the bottom memberv of the draft gear frame and extends rearwardly to a vertical pivot pin 25- on the truck bolster `26. This arm 23 is held yieldingly by a rod 27 which passes through a slot inthe arm 23, and carries springs 28, interposed between the arm 23 and brackets 29, which project from the truck bolster and carry the arm 23.-

Forthe purpose of supporting the vertical pivot pin on which the draft swings radially,gI preferably provide the rear carryiron 30, of the draft gear, with a bracket 31 .which projects under the vertical pivot pin y 19, so that in case the pin should break, .the

bracket 31 will hold it from dropping, although other pin supporting means may be'V rovided.

y constructing the'car with the proper dimensions between the truck bolster 26 and the end sill of the car, the draft gear frame may be adapted to receive any kind of draft rigging which is now in use, and when the ordinary Master Car Builders coupler is inserted in the frame itl will not project beyond the end Sill more and standard distance.

As shown in the drawings, the center sills 32 ofthe 'car frame areso placed that the longitudinal center line of the coupler shank is coincident with the longitudinal center line of the draft rigging and it is also coincident with the center line of the pivotal support 19 and with he central plane of the center sills, so that the draft gear will swing horizontally in the" plane of the center line of the center sills. As the support forming the resistance has its center substantially in the center line of the center sills, the bufting 'stresses will be imparted to the draft gear equally in its upper and lower portions, thereby parts ofthe draft gear upwardly or downwardly. This also results from the center lineof`the couplerbeing in the horizontal center `line of the pivotal bearing.

In theV drawings, I show myy device in what I deem to be its preferable form, but

` it will be understood bythose skilled in the art, that it is capable of many modifications,

form vand construction to adapt it to than the ordinary l avoiding any tendency to deect of the coupler draft gear or spring rigging which I have specifically shown -and dearranged to receive the shank of a coupler, said socket being recessed to receive the narrower shank of another coupler. v
