Application filed September 6, 1924 seen no. 736,210, g
Y T all whom it may concern:
Be it known that we, GEORGE WV. 'D IT MORE and CLIFTON WI SHERMAN, citizens of the United States, residing at Albany, in
the county of Albany and; State of New York, and Hamilton, county'of Went-worth, and Province of Ontario, Canada, respectively, have invented a new and useful Im provement in Draft Yokes, of which the; fol owing is a specification.
This invention relates to a railway cars ofthe type having longitudipocket which receives the rear set of elements ofthe buffing mechanism.
. The object of this-invention is to a draft yoke of this character in whichthe Qfrolnt parts of the longitudinal bars are se curely connected and form 'a strongand durable pocket in which'the enlarged butt of the draw bar shank may be i'nounted so [as to be capable of being easily and readily, mounted and dismounted in adirection transversely of the draft yoke; also toconstruct the longitudinal bars relatively t-o'the front stop so that the bufling strains extent endwise to these bars and thereby. relieve from shearing strains the pins which connect thedraw bar shank with the draft bufiing elements.
ofthe draw bar are transmitted to a large yoke; and also to provide ribs on the longitudinal bars from the front ends thereof to the central stop for the purpose of strengthening the yoke and enabling the same to more effectively transmit buffing strains from the front parts of the longitudinal bars to the central stop and the rear In the accompanying drawings Figure 1 is a side elevation of a draft yoke embodying our improvements;
Figure 2 is a top plan view .thereof. Figure 3 is'a longitudinal section taken on line 33, Figure 1;
Figure f is a bottom plan View of the draft yoke. I l
Figure 5 is a side elevation viewed from the side opposite to Figure 1. V
Figure 6 is a vertical section taken on line 66, Figure 5. c 1
Similar characters ofreference indicate like parts throughout the several views.
, m'echanism; draft yoke forprovide The numerals'lll and represent the upper and lower [longitudinal bars of the draft [yoke which are associated with other parts to form a front-pocket for thereception of theshankkof the draw bar, anintermediate pocket' which receives the front section or set of elements of the. 'buffing mechanisnn;
and a rear pocket which receives therear section or, set of elements of thebufiing The front parts or wall of the front pocket,- and". an'upof the longitudinal bars form the top and I bottom'of' the front H r pocket, At the front ends of these bars 'jis a, pair of vertical lugs" 12,13 which project" toward each other and'form th'ejfront'side right front stop, '14 connects the bars at a. r distance; rearwardly. from the lugs and forms the rear wall or side of this pocket;
,In this front pocket is removablymounted the shank of the coupler draw bar which has a reduced'neck 15 arranged between the lugs 12, 18 and a vertically enlarged butt 16 at the rear end of. this, neck which is arranged in'the front pocket andbears with .7
its-rear side against the front stop 14 and p provided with forwardly facingshoulders 17, 18 which engagewith the rear or inner sides of-the upper and lower lugs 12,
The butt of the draw bar shank is se-f cured in this pocket by one or moreheaded pins 19, preferably two, passing vertically through corresponding openings in the butt and thefrontpartso'f the, upper and lowerbars ,and bearing with their heads" against the top of the .upper bar and held against displacement by cotters or keys 20" passing through the pins below the-bundersideiof the lower longitudinal bar. g On one lateral side of the draft yoke the front pocket is entirely open so asto permit the free introduction of the coupler but-t into this pocket as well as the removal of the same therefrom. n The opposite lateral side of the front pocket ispart-ly obstructed or closed by; two" thick inner longitudinal ribs 40 arranged on the inner sides of the:
