DRAFT-RIGGING FOR CAR-S.

SPECIFICATION formingpart of Letters Patent No. 739,770, dated September 22, 1903.

Application filed June 15,1903.

T0 aZZ whmn it may concern:

Be it known that we, I ORVILLE WRIGHT and JOHN H. FARLOW, citizens of the United States, residing at Baltimore city, in the State of Maryland, have invented new and usefulv Improvements in Draft-Rigging for Cars, of which the following is a specification.

The objectof our invention is the production of an improved draftand butting gear or rigging for cars which shall be adapted to' embrace as a part thereof, according to the repairs may be made when necessary veryeasily and. quickly and without taking the car tothe shops, which shall be very strong and capable of withstanding the shocks of severe service, which shall distribute the strains throughout the length of the drafttimbers or supports or sills, which shall ad: mit of the removal and replacement of a coupler and draw-bar without the removal of the spring mechanism, and which shall possess other and desirable novel features of construction constituting the same a superior. instrumentality for performing the requisite functions.

With this end andpurpose in view our invention consists in certain novelties of con struction, arrangements, and combinations of elements and parts hereinafter set forth and specified in the claims.

The accompanying drawings illustrate a complete example of the physical embodiment of our invention constructed according to the best mode we have so far devised for the practical application of the principle.

Figure l is alongitudinal sectional view in elevation of Fig. 2. Fig. 2 is ahalf top plan View and a horizontal sectional View of the draft-beams and the parts of the rigging combined therewith as seen when removed from the floor-frame. Fig. 3 is a face view of a draft-beam or support.v Fig. at is a cross-section of Fig. 3'throu'gh one of the lugs and at one side of the other lug. Fig. 5 is a longitudinal section of Fig. 3. Fig. 6 is a face view of a yoke. Fig. 7 is an end view of Fig. 6. Fig. 8 isa longitudinal section of Fig. 6.

Fig. 9 is a cross-section of Fig. 1, one half taken on a line through a follower-block and the otherhalf through the lugs on a draft- ;beam and on a yoke.

Referring to the several figures, the numeral 1 designates the central stringers of the car-floor. frame; 2, the end sill; 3, the bufferblock; 4, the draft sills or beams, which are of metal in this-example; 5, bolts which secure the draft-beams to the sills and huEer-block; 6, the top lugs on the draftbeams; 7, the bottom lugs; 8, holes through the lugs for bolts; 9, the front elongated slots ,in the beams; 10, the center slots; 11, the

rear elongated slots; 12, strengthening-ribs around the slots, which also provide large bearing areas for the pins; 13, the carry-iron; 14, the angle-iron friction-plate; 15, the drawbar yokes; 16, the slots at the front ends of the yokes; 17, the central elongated slots; 18, the end elongated slots; 19, the narrowed portions of the yokes; 20, the lugs onthe faces of the yokes; 21, bolts which unite the draft-beams and pass through the lugs on the same; 22, the draw-bar with acoupler-head of any approved type; 23, a slot in the draw-bar; 24', a holein the end of the draw-bar; 25, the front follower-block; 26, an elongated slot in the block; 27, lugs on the block, the front one being seated in the end of the draw-bar andthe other one supporting the end of a spring; 28, the rear follower-block 29, a slot in thevrear follower-block; 30, a lug on the face of the block to support the end of a spring; 31, a follower-pin; 32, the enlarged central portion of the pin located between the lugs on the draft-beams and on the yokes 33, two perforated follower-plates on the follower-pin; 34, the front spring; 35, the rear spring; 36, the three equalizing-pins, and 37 represents cotters in the ends of the pin.

On reference to the drawings itwillbe seen that-when the parts are assembled the front equalizing-pin closely fits the slot in the draw-bar and the ends are located within the centers of the elongated slots in the draftbeams, that the rear pin is located at the rear ends of the slots in the draft-beams and in the yokes, that the central pin is immovable and that the front follower-block and the yokes move relative to this pin, that the follower-pin moves longitudinally, and that the plates and move between the lugs on the draftbeams a distance equal to the narrowed portion thereof.

The modus operandi is as follows: In drawing, the draw-bar imparts motion to the yokes and the front and rear equalizing-pins, the lugs upon the yokes engaging the front follower-plate advances it,compressing the front spring, the rear follower-block simultaneously compresses the rear spring, and. when the springs have been compressed, for instance, two inches the lug on the rear fo llower-block, the rear lug on the front follower-block, and the ends of the follower-pin come in contact. Simultaneously the front and rear pins reach the ends of the slots in the draft-beams and all additional strains above those taken by the springs are imparted ted to the draft-beams at three points in each,

and as thus distributed no injury will result to any part of the rigging.

The method of assembling the several parts and elements of the gear and the method of replacing an element or part will be readily understood by any person skilled in the art from an inspection of the drawings, and therefore the same need not be specifically set forth.

While we have illustrated and described only one complete example of the physical embodiment of our invention,we do not thereby intend to limit the scope thereof tosuch embodiment, inasmuch as the principle may be applied under different forms and by other modes. Metallic center sills with slots may be usedin place of the sills and draft-beams shown, the draft-beams made separate or integral, the shape of the follower-blocks be altered, a single spring used in place of two springs, and other modifications, substitutions, omissions, additions, and changes be introduced at the will and choice of the manufacturer without constituting substantial departures.
