The objectof the invention is to provide an arrangement of friction draft gear for railway cars wherein is employed a; rear abutment or stop casting secured to' the sills for preventing the forward movements of the friction shell. i

rlhe invention furthermore consists in the improvements of the parts and devices and in the novel combinations of the parts and devices herein shown, described or claimed. :in the drawing forming'a part of this specification, Figure 1 is a vertical, longitudinal central section of a draft rigging showing one embodiment of my improvements 1n connection therewith. Fig. 2 is a horizontal sectional `view of the structure illustrated in Fig. 1 and taken on the line 2--2 thereof. Fig. 3 is a vertical, transverse sectional view taken substantially on the line 3--3 of Fig. 1. And Figs. 4 and 5 are views corresponding respectively with Figs. 1 and 43 but illustrating `another em-v bodiment of the invention, Fig. 5 being taken onthe line 5-5 of Fig. 1.

1n said drawing, and referring to the structure illustrated in Figs. 1 to 3, 10-10- denote channel center or draft sills ofv usual form, 11 a draw bar, 12 a cast yoke having ahooded forward end to which the draw bar is connected by a coupler key 13 slidably mounted in suitable slots in the draft sills. Mounted within the yoke 12 is a friction draft gear of well known type desig-' rated generally byv the reference A. Extending between and connected to the sills at the rear of the gear A is a heavy abutment or stop casting designated generally by the reference B.

L7llhe castingl B, as shown, comprises a front vertical stop face 14, parallel side walls 15-15 riveted to the sills 10, upper wall 16, reinforcing horizontal danges 1Y0- 170, and a forwardly extended, pref- .ated in the usual manner.

, cage.

erably integral arm or plate 17, the latter extending over the friction gear for the pur ose hereinafter described.

T e gear A, as shown, comprises a combined friction shell and spring casing 18 with the shell at the rear, springs 19, and friction elements 20, the latter bearing against the rear end of the yoke 12, the yoke in turn normally abutting, the vertical face 14- of the casting Bf ln bud', it is apparent that the yoke and inner element of the friction mechanism are prevented from movement by the casting B and hence as the friction shell moves rearwardly the friction gear will be actuln draft, it is necessary to prevent longitudinal movement of the shell 18 and for this purpose, the arm 17 is provided at its front end with a pair of laterally s aced, depending lugs or shoulders 21-21w ich coperate with correspending shoulders 22-22 formed in the upper face of the friction shell and spring ln order to reinforce the shoulders 21, the arm 17 is provided on its under face with ribs 23, 23, see Fig. 3. The gear and yoke are supported by means of a saddle plate 24 which is detachably bolted to the lower flan es of the draft sills by asucient number o bolts to withstand a heavy pulling strain, three of such bolts being shown in the drawing. Said saddle plate 24 is provided on its upper face with a pair of upstanding lugs or shoulders 25-25, which also engage corresponding shoulders 26-26 formed on the lower face of the friction shell and spring casing 18. rlhe shoulders 25 are arranged opposlte the shoulders 21 so that the casting 18 is engaged at four points during the draft actions of the gear. llt will also be noticed from Fig. 3, that the four lugs 21 and 25-form guides for the upper and lower arms of the yoke.

ln assembling the draft rigging, the friction gear is first laced within the yoke and then the yoke an gear are raised-vertically,

with the shoulders 22 of the casting 18 er1- gagin behind the shoulders 21. Thereupon is provided with asingle, centrally located transverse shoulder 121 on its underface which coperates with a single upwardly ing depending shoulder 126 which 1s arran ed 'to coperate with la transversely exten ing shoulder 125 formed on the krear edge of the saddle plate 124. v In this construction, a horizontal yoke 112 is employed 'instead of a vertical yoke and in order to support and guide said yoke, the saddle plate 124: is provided with upstandin flanges 40 near each end thereof on whic the arms of the yoke reciprocate back and forth. The transverse shoulder 121 of the casting B is suitably reinforced by longitudinally extendin ribs or anges 123. The' manner of'assemb ing the gear illustrated in Figs. 4 and 5 will be obvious from the preceding description.

1. In a draft rigging, the combination with draft sills, of a ear including a fric-4 tion shell between said sills, an abutment Kcasting at-the rear 4of the gear and secured to the sills, said casting having an arm extended forwardly to overlap said shell, said arm and shell having coperating engaging shoulders arranged to prevent forward movement of the shell relatively to said casting under draft.

.2. In a draft rigging, the combination with draft sills, of aJgear includin a friction shell between sald sills, an a utment casting at the rear' of the gear and secured to the sills, said casting having an arm extended forwardly to overlap said shell, said arm and shell having coperating engaging shoulders arranged to prevent forward movement of the shell relatively to said casting under draft, and' a saddle plate extending between the sillsbeneath the gear, said saddle plate and friction shell having coperating'engaging shoulders to prevent forward movement of the shell under draft.

3. In a draft rigging, the combination with draft sills, of a gear including a friction shell mounted between said sills, an abutment casting at the rear of the gear and secured to said sills, said castin having a forward extension over the iction shell, said extension being provided with a depending shoulder, said shell havin a shoulder on its upper side engaging the rst named shoulder on the rear side of the latter to thereb prevent forward movement of the shell re atively to said casting under draft, and means for supporting the shell.

4. In a draft rigging, the combination with draft sills, of a gear including a friction shell mounted between said sills, an abutment casting at the rear of the ear and secured to said sills, said casting aving a forward extension over the friction shell, said extension being provided with a depending shoulder, said shell having a shoulder on its upper side engaging the first named shoulder on the rear side of the latter to thereby prevent forward movement of the shell relatively to said casting under draft, and means for supporting the shell. said means includin a saddle plate extending beneath the she said saddle plate and shell having coperating engaging shoulders also adapted to prevent forward movement of the shell under draft.

5. As an article of manufacture, an abutment casting adapted to be mounted between and secured to draft sills of a car, said casting having a vertical abutment face at its front end and a forwardly extending integral arm adapted to overlap a shell-like memberof a draft gear, said arm having a shoulder near its front end adapted to c0- operate with a shoulder of said member to prevent forward movement of the latter under draft.

In witness that I claim the foregoing I have hereunto subscribed my name this 29th day of August, 1916.
