DRAFT-RIGGING FOR PILOT-COUPLINGS.
Application filed December 6, 1912.
To all whom it may concern Be it known that I, EDMUND P. KINNE, a citizen of the United States, and resident of Alliance, in the county of Stark and State of: Ohio, have inventedcertain new and useful Improvements in Draftltigging for Pilot-Couplings, of which the following is a specification.
My invention relates to railway cars and has particular reference to a novel draft rigging for application to pilot beams of I engmes.
Tt is the common practice to attach couplers the pilot beams of locomotives without inter-posing a draft gear, the connection being rigid with relation to longitudinal. pull and buff but being pivoted in order to permit limited sidewise movement. Such arrangement, however, throws excessive strains on the coupler particularly in bull'- ing and therefore the principal object of my inventibn is to provide a draft rigging for use in this connection.
Tl; desirable and not unusual to provide an ntegral buffer beam with a recess in w :h the coupler is secured. T hereiore anr object of my invention is to provide c aft rigmng which may be associated with such an integral beam without weakening the beam. in my construction the draft riggi'ing may be assembled and then inserted as a unit within the recess in the beam, being held in place by a removable lrev.
above indi ftlifitl it is desirable that the cou 'iler should be permitted limited sidewise inovcinei'it and it is also desirable that the coupler should be automatically centered. l. have provided such means in my desig s.
Cifhe invention will be more readily under stood by reference to the accompanying drawings, wherein,
l igure 1 is a plan section showing an integral butler beam and king-post casting within which my novel draft rigging is secured; Fig. 2 is an end elevation of the construct in shown in Fig. 1; Fig. 3 is a lont l section through the center of the non shown iii-Fig. 1; Fig. 4 is a on the line ll of Fig. 3; Fig. 5 is .ection on the line of Fig. 3; Figs. 5:1 and are perspective views of yoke, follower blocks, key and shim respectively later to be described,
Specification of Letters Patent.
jects. Formed near the mouth of the rec Patented Get. 2%, Serial No. 735.226.
Referring more particularly to the drawings, it will be seen that I provide an integral butler beam 10, combining therewith a king-post casting 11, having a king-bolt opening 12 therein. llithin th; combined buffer and king-post iastings, ll pmvirfle a recess 13 within which the draft aging" is seated. This recess has no open...v except that through the outer face oi? the scare 10, through which the shank of the coupler toro- 13 are vertical grooves 14, one on each of the opening within which a Ushauf fastening key 15 is seated. It will be by reference to l? l and 2 that grooves 14: provide seats or bearings for the two legs of the U-shaped fastening member,
the bearing being throughout practically the entire length. of the key whereby conr plots longitudinal shear would necessarily be etl'ected before the draft rigging could free itself. The buffer casting provided at the top and bottom at a point contiguous to the recess 13 with lips or enlargei'ncnts 16, 17. The cross bar of the fastening key to rests behind the upper enlargement is, thus removing it from possibility of injury and providing greater resistance to displace ment under longitudinal pull.
The coupler 18 herein shown, is provided with a short shank 1.9, apm'tured to accommodate a pivot pin 20, having a large head 21. This pivot pin also cooperates with slots 22, formed in the longitu-flinal members of a primary yoke 23, which yoke is best shown in l ig. (S. A trai'lsvers -wall 24 is provided in the yoke against which the forward draft springs 25 abut. Draft Springs 26 abut the rear vertical wall. of the yoke. As best shown in Figs. 1, 3 and 7, ll provide novel front and rear follower blocks 27, 28, respectively. The forward block is provided with a front extension 29, of a width narrower than that of the block, thus providing shoulders 30, which shoulders coiiperate with the legs of the fastening key 15, as is clearly shown in Fig. l. The extension 29 is squared and abuts the squared end of. the shank 19. Thus it will be seen that while the coupler is permitted a limited sidewise rotation around the pivot pin 20, the squared end causes the recession Obviously also the dratt yoke will he pulled. forward thus 65, tively. to said yoke,
forms in effect a secondaryor huffing yoke;
Insuch position the inner face 31 of the rear follower 28 is held against the partition 24 in the yoke by the force of the spring 26; also the end wall of the yoke 23 is held against the walls formed as apart of the king-post casting 11. Thus under buff the force transmitted by the coupler shank 19 extends to the front follower '27, whereby the spring 25 is compressed,.then to the rear follower 28, through the cooperating legs on the-two followers and the consequent compression of the spring 26. This requires that the pivot pin shall travel rearward in the slot 22. On pull, the parts being in the position shown, the strain is transmitted to the yoke 23, and the followers being held against forward movement by means of the key 15, the springs 25, 2.6, are compressed byreasonofthe partition and the rear vertical wallof the yoke.
The coupler shank, as shown, is of a slightly less height than the space between the longitudinal members of the yoke 22, in order that the height of the coupler may be adjusted as required. This I accomplish by means of thou-shaped shim 33, as best shown in Figs; 3 and 9, this shim being provided with. upwardly projecting dowels 3%,- which may be seated in the recesses 35, 3G, in the upper and lower walls respectively of the yoke. Such a shim may be inserted from the mouth of the yoke, is held in place by means other than the pivot pin and may be readily shifted as required.
It will be noted that the draft rigging, complete as shown, may be assembled apart from the car or locomotive, then placed in the recess 13, and the key 15 inserted. Furthermore, a coupler may be readily removed. and replaced by another without disturbing other parts ofthe mechanism. The arrangement is extremely simple and rigid and provides a cushion for use on pilot beams of "locomotives in which practically all the ad vantages of the usual forms of tandem gear are secured as applied to railway cars.
It willbe obvious that modifications may be made in the construction shown and such modifications as are within the scope of my claims I consider within the spirit of my invention. f
