WILLIAM H. MINER, F CHAZY, NEW YORK.
DRAFT-RIGGING FOR RAILWAY-CARS.
Application led April 18, 1914.
j T0 all whom t may concern Be it known that l, WILLIAM H. MINER, a
.citizen of the United States, residing at Chazy, in the county of Clinton and State of New York, hjave invented a certain new and useful Improvement in Draft-Rigging for Railway-Cars, of which the following is a full, clear, concise, and eXact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to improvements in draft rigging for railway cars.
The object of my invention is, to provide a draft rigging of efiicient operation.
In the drawings forming a part of this specification, Figure 1 is a side elevation, partly in vertical longitudinal section, of a draft rigging embodying my invention; Fig. 2 is a plan view, partly in horizontal section, on line 2 2 of Fig. l; Fig. 3 is a cross section taken on 'line 3-3 of Fig. 1; Fig. 4 is a perspective View of the rear follower; Fig.y 5 is a detail perspective view showing a modification of one of the stop shoulders.
Referring to the drawings, the numerals 5h55 indicate draft members, or parts of the car-frame to which the draft rigging is applied; 6 a draw-bar, only the rear end thereof being shown in the drawings, the said draw-bar having a transverse slot 7 for the passage of a coupler-key 8, the said coupler-key extending through slots 9-9 in the draft links 10-10 and being received at its ends in the slots 11--11 in adjacent portions of the draft mem-bers 5. The slots 11-11 are longitudinally extendedto permit forward and rearward movement of the key therein, the slots 9 in the draft links being rearwardly extended to permit the rearward travel of the key therein on rearward movement of the draw-bar. Near their rear ends, the draft links 10 are provided with the transverse slots 12--12 adapted to receive the transverse rear key 13, the ends of the key 13 passing through slots 14-14 in adjacent portions of the draft members, the said slots 14 beinglongitudinally eX- tended to permit longitudinal movement of the key 13 therein. Upper and lower stop members 15 and 16, respectively, are secured between the draft members, the upper stop member consisting preferably of a channelshaped member having the main web 17 and lateral up-turned flanges 18-18, by means of which the said stop member is secured to Speciicati'on of Letters Patent.

the draft members, preferably by the rivets 19-19. Similarly the lower stop member 16 is a channel-shaped member having a main web 20 and lateral dependent flanges .2l-21, by means of which the said stop member 16 is secured to the dr'aft members, preferably by the bolts QQ-QZ. Each of the stop members is provided intermediate its ends with a vertical opening Q3, the material forming the ends of each opening being inturned, forming the upper front stop shoulder 24, the lower front stop shoulder 25, the rear upper stop shoulder 26, and the rear lower stop shoulder 27. A draft gear is mounted between the draft members, the draft gear comprisinga shell 260, consisting preferably of a spring-cage Q70 and a. preferably integral friction shell Q8. The friction shell is preferably a hollow cylinder 1n form, and contains the friction elements 29', consisting preferably of a plurality of shoes 30-30 and a wedging member 31 therefor. The wedging member is connected to a movable spring seat 32 mounted within the spring-cage 270 by means 0f a connecting bolt 33, the nut of which is received in a forwardly opening recess 3l in the wedge, and the head of which is received in the rearwardly opening recess 35 in the movable spring seat. The movable spring seat is provided with a forwardly projecting collar 37 adapted to engage against the friction members, preferably the friction shoes 30-30 upon the compression of the spring 38 which is mounted within the said collar and between the movable spring seat and the friction shoes 30. The spring cage is preferably open at its upper face 39, its lower face 40, and the rear end Ll1, the cage consisting preferably of the front plate 42 and the spaced-apart lateral plates 425-43. Vithin the spring cage is mounted spring elements, preferably an upper set 44 and a lower set 45, each set preferably comprising an outer spring 46 and an inner spring 17 nested therein. The springs thus mounted in vertical twin arrangements are seated at their forward ends against the movable` spring seat, and at their rear ends against the rear follower 48, the rear follower consisting preferably of a plate +19 forwardly provided with upper and lower lugs 50 and 51, respectively, the inner spring 47 of the lower set of springs being seated about the lower lug, and the innerl spring -17 of the upper set of springs being seated about the upper lug. The rear follower is provided with rearwardly preferably integral, arms 432-52, and a preferably integral sleeve 53 between them. The sleeve and arms are provided with registering transverse slots 54 through which passes the rear key 13. The spring cage of the shell is preferably7 of a general box-like shape, and is received within the vertical openings in the stop members, the forward plate 42 thereof abutting against the front stop shoulders 24 and 25, and the rear end thereof abutting against the rear stop shoulders 2G and 27. y
The friction shell is of lesser vertical height than the spring cage, and is received between the upper and lower stop members forwardly of the vertical openings therethrough. Thus the shell of the draft gear is secured against longitudinal movement between the draft members. vThe shell is provided along the lateral faces of the spring cage with outwardly extending longitudinal shoulders -60, and the lower stop member is provided along the edges of the vertical opening thereof with shoulders (S1- 61, preferably angularly formed, as indicated at the numerals (i2-G2 in Fig. 3 of the drawings. The lower stop member is removably secured to the draft members bythe bolts 22-22, and the said lower stop member through the shoulders G1 thereof in their engagement With the shoulders 60-60 with which the springcage 27 is pr Wided, aid in supporting the shell in its position between thedraft members. In preferable construction, the upper and lower portions of the friction shell are in close proximityA width to be mounted between the said plates,
and may be forwardly drawn into the spring cage in its forward movement.
On rearward movement of thedraw-bar, the same engages the friction elements in the shell, the coupler-key 8 traveling rearwardly in the slots 9 in the draft links 10; the compression resisting parts within the shell are brought into compression resisting action, the same being rearwardly stopped by the rear follower, which is held against rearward movement by the rear stop shoulders 2C and 27 extending transversely between the draft members.
extended spaced-apart,
On forward movement of the draw-bar, the coupler key 8, through engagement against the forward ends of the slots 9 in the draft ,links 10, draws the rear key 13 forwardly, the key forwardly actuating the rear follower and sliding forwardly in the slots 64: in the spring cage, thus compressing the spring elements between the rear follower and the movable follower, the movable follower being stopped against forward movement by its engagement against internal shoulders 66-66 at the forward end of the spring cage, the spring cage in forward movement of the draw-bar being stopped against the front stop shoulders. In rearward movement of the draw-bar, the spring cage is stopped against the rear stop shoulders. The draft gear may be dismounted from between the draft members by removing the bolts 22 iand dropping the lower stop member, and may be mounted between the draft members by reversing the operation.
' In Fig. 5 of the drawing, a different form of stop shoulders for the upper and lower stop members is shown. In said figure` the numeral 70 indicates the end of one'of the channel shaped stop members 71, the end of the slot in said stop member being provided with a stop shoulder 72 which comprises a U-shaped clip having longitudinally extending, spaced flanges 7e-74 between which the transversely extending portion 75 of the stop member is received. The U-shaped clip is secured to the stop member by any suitable v means such as the rivets Z6-76 I claim l. In a' draft rigging for railway cars, in combination, draft members, upper and lower stop members having vertical openings therein and secured between the draft members, a shell having a spring cage, and
friction shell mounted between the draft members, compression resisting elements within the shell, a draw-bar, and means operatively connecting the draw-bar tov the compression resisting elements, the spring cage of the shell being received4 in the vertical openings in the stop members, and secured against longitudinal movement there- 1n.
