JOHN F. O'CONNOR, OF CHICAGO, ILLINOIS, ASSIGNOR TO WILLIAM H. MINER, OF CHAZY, A NEW YORK.

' Chicago, in the county of Cook and State of DRAFT-RIGGING.

Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed November 27, 1916. Serial No 133,564.

To all whom it may concern:

Be it known that I, JOHN F. OQoNNoR, a citizen of the United States, residing at draft riggings.

The object of the invention is to provide a draft rigging for railway cars, and more particularly a draft rigging of the spring type, having relatively cheap stop members formed from steel plates.

In the drawing forming a part of this specification, Figure 1 is a longitudinal section of a portion of a draft rigging illustrating my improvements. Fig. 2 is a horizontal sectional view of the structure illustrated in Fig. 1 and taken on the line 22 thereof. Fig. 3 is a transverse, vertical section, taken on the line 33 of-Fig. 1. And Fig. 4 is a detail view illustrating one of the blanks from which my improved stop member is formed.

In said drawing, 1010 denote draft sills of a car underframe to which are secured my improved stop plates A, A. Each of the latter is formed from a blank of the shape illustrated in Fig. 4. As there shown, the

blank is of generally rectangular form having recesses 1111 on each edge thereof, thus leaving four corner shoulders 1212. The blank is centrally perforated as indicated at. 13, for the purpose hereinafter described, and is also slotted at its front edge as indicated at-14. The blank, cut to the shape indicated in Fig. 4, is then bent substantially along the lines 15-15, thereby rendering the stop plate of substantially. U- shape in cross section, as clearly indicated in Fig. 3. When so bent, the shoulders 12 12'will extend toward each other, thus forming upper and lower front and rear stop shoulders 16-16. The-stopplates are se cured to the sills by suitable means such as the rivets shown. The stop plate above described is designed more particularly for a spring ear of the twin type that is one empldyihg front and rear followers 1'f17 and vertical twin arranged springs 1818, the latter each consisting of inner and outer nested coils.

To operatively connect the gear with the draw bar 19, a horizontal yoke 20 is provided, the arms of the latter being slotted to receive the coupler key 21, the latter also extending through elongated slots 22 in the sills and extending partly into the recesses 14 of the stop plates.

To limit the movement of the gear and prevent setting of the springs, I employ a stationary key 23 which extends transversely between the springs 18 and throughslots 24 in the side arms of the yoke, the

slots 13 in the stop members and correspondw ing slots 25 in the sills. The key-23 is; stationary and so spaced fromthe front and rear follows that the latter will engage with said key at the end of the permissible movement of the draw bar in either buff or draft. A saddle plate 26 is used toproperly support the gear.

From the preceding description, it will be seen that the stop members can-be made very I cheaply from steel plates and form eflicient stop members for the followers to engage.

Furthermore, said stop'members,,when. applied to the sills, act 'asrreinforcing memf bers for the'latter and increase the bearing area for the fixed key 23 which serves as a limiting stop, thus distributing the shocks i over a'greater area of the sills.

I claim: 1. In a draft rigging, the combination with draft sills, a draw bar, a yoke, and cushioning means, of stop members secured to said sills, each stop member comprising a plate bent to U-shape in vertical cross section with the arms extending horizontally, said arms having inwardly projecting shoulders.

2. As an article of manufacture, a stop member for draft riggings, said member consisting of a plate bent to U-shape in ,ver tical cross section, the arms of the U having inwardly extending shoulders at the corners thereof.

In witness that I claim the foregoing I have hereunto subscribed my name this 22d day of Nov., 1916.

JOHN F. OCONNOR.
