DRAFT-RIGGING FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Jan. 28, 1919.

To all whom it may concern Be it known that I, JOHN F. OCONNOR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have 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 cheap and efiicicnt draft rigging for railway cars.

In the drawings forming a part of this specification, Figure 1 is a vertical longitudinal section, partly in side elevation, of a draft rigging embodying my invention.

Fig. 2 is a cross section taken on line 22 of Fig. 1. Fig. 3 is a cross section taken on line 33 of Fig. 1, and Fig. 4 is a horizontal section taken on line 41 of Fig. 1.

' Referringto the drawings, draft members are indicated at the numerals 55, said draft members preferably comprising'cham nels having the upper and lower out-turned flanges 6-6 and the intermediate web 7. The channels are perforated as at 8-8 to receive the longitudinally spaced apart front and rear transverse keys 9 and 10, respectively.; -,A yoke 11 is mounted upon the keys, between the draft members, the said yoke comprising a pair of spaced apart arms 12-12, the said arms being made of commercial channel bars having their flanges 13-13 inturned. The said yoke is connected at its forward end to the draw-bar 14, which is provided with the lateral perforation 15 to receive the coupler key 16, the

ends of the key 16 being extended to the perforations 1717 in the arms of the yoke.

he said perforations '17 in the yoke are located substantially midway between the up er and lower flanges of the channel bar,

an the said bars are also provided with upper and lower transverse perforations 1818 for the passage of the upper and lower keys 19 and 20, respectively, the said keys being extended through the yoke and engaging at their back edges respectively against the upper draw-bar shoulder 21 and the lower draw-bar shoulder 22. The ends of all three keys for connecting the coupler to the yoke are provided with suitable means, as for instance the cotters 23 to prevent the aocidental displacement of the key. Intermediate its ends the yoke is provided with the transverse perforations 2 1-2-l to receive the key 9, and near its rear ends with the transverse perforations 25-25 to receive the rear key 10, the said perforations 25 and the slots 8 in the draft members, in whichthe rear key is received, are all forwardly extended, as clearly shown in Fig. l of the drawing. The slots 8 in the draft members and the slots 24 in the yoke are all rearwardly extended, as clearly shown in Fig. i of the drawings. A central spring 26 is mounted between the keys 9 and 10 and between the limbs 12 of the yoke. On each side of the yoke and between it and the adja'cent draft member is mounted between the keys 9 and 10 an outer spring 27. A tie plate 28 secured to the lower flanges 6- of the draft members 5, by suitable means, as for instance the bolts 29, supports the yoke, the center spring 26 being supported between the limbs of the yoke by means of the arm 30 upwardly extended from the tie plate'28 and the outer springs 27 are each supported by an upwardly extended arm .31, which is preferably integral with the tie plate 28. Above each outer s ring 27 is mounted an upper spring gui e 33, having a vertical portion 34 by means of which it is secured, as for instance by the rivets 35, to the adjacent draft member 5. The perforations 8 in the draft members are provided at their lower edges with the outturned flanges 37-37, which form a broad wearing face for the keys 9 and 10. On rearward movement of the draw-bar, the rear face 40 thereof engages against the key 9 and through this engagement and the engagement of the yoke upon said key, the said key is forced rearwardly, compressing the springs between it and the rear key 10, which is held against rearward movement in the rear ends of the rear slots 8, the yoke in its rearward movement sliding upon said rear key 10.- In forward movement the key 9 is stationary and the rear key 10 is drawn forwardly by the yoke, the said yoke sliding upon the key 9. In such forward movement the springs are compressed by the rear key 10 against the key 9.

In preferable construction, the various key perforations in the yoke are readily out from the commercial channel bars and the key slots in the draft members are cut in the web 7 of the draft members, the cut portion of the web being left integral along its bottom edge and then bent outwardly to form the flanges 37, and also in preferable construction, the spring supporting arms 30 and 31 in the tie Plate 28 are blanks cut at one end in the two sides and at the sides within the tie plate and then bent upwardly to form the arms, as shown in Fig. 3 of the drawings.

I. claim 1. In a draft rigging for railway cars, in combination, draft members, a pair of channel bars forming a yoke mounted between the draft members, a pair of longitudinally spaced keys mounted in the draft members and extending between the same, a spring between the bars of the yoke and further springs, one at either side of the yoke, all of said springs being seated between the said keys, and means for connecting said channel bars'to a draw-bar.

2. In a draft rigging for railway cars, in combination, draft sills, a draw bar, a pair of parallelly arranged members forming a yoke mounted between the draft sills, said members being extended alongside the side faces of the draw bar and secured thereto, a pair of longitudinally spaced keys mounted naeaeea in the draft sills and extendingtherebetween, said keys. passing through slots in said-members, a spring mounted between said yoke members, and additional springs, one at either side of the yoke, all of sand springs being seated between the keys and confined between the sills.

3. In a draft rigging for railway cars, the combination with draft sills, of a yoke mounted between said sills, said yoke comprising two members having horizontal flanges extending lengthwise thereof, springs mounted between said sills and between said members, and front and rear stop elements for said springs.

4:. A yoke for railway draft riggings comprising two separate, independent channel shaped members having the Webs thereof extending vertically and longitudinally, the flanges of said channel shaped members being turned inwardly whereby to form a pocket within which is adapted to be received a cushioning member.

In witness that I claim the foregoing I have hereunto subscribed my name this 7th day of August, 1916.
