Application med December To @ZZ 'itu/tom 'it -m f5.1/ @minerai Ie it known that I, SVEN JULiUs STRiD, a citizen of the United States of America, residing at Chicago, in the county vof Cool; and State of Illinois, have invented a new and useful'Improvement in an JAdapter for Brake-Gear lilouiitings, or which the following is a full7 clear, and exact description, such as will enable others skilled in the art 0 to make and use the saine.V

My present invention relates to means for readily mounting` the gearing' of a railway carV brake, and has special reference to what I terin an cadapter", theuse of which permits the manufacturer to produce the gears, housing', etc., as a unit, so that one structure nia-y be VVused -for a number of types ofv car construction, andlwith my adapter this unit may be 'readily secured to the particu-V larV car to be* equipped.`v

The use of this structure ellects a considerable saving` in the manufacture of these gear structures, because of the'iiaet that it has heretofore been the generalpractice to prac` tically re-design the housingo the gear mechanism tor each type of installation re quired, whichvof course adds considerably to thecostot production. With the present structure, with they lgears, housing, etc., furnished as a unit, it is only necessary to sub# stitute the particular adapter `for the particular installation Also the use of the hereinafter described structure 'makes it, pos sible to quickly detachand remove the unit containing the gears, housing, etc., from 'the car without the necessity ot lhaving' tocut rivets, or remove bolts and nuts for the' reason that the adapter, while it is positively interloclied'with the housing', may be readily disassembled b y the simple removal ot a pin. I prefer to carry out my invention and: to accomplish the divers objects thereof in substantially the manner hereinafter fully described andas more particularlypointed out in the claims, 'reference beintghere made 'to the accompanying Idrawings" that iform a part ot this specification.

In the drawings' z- Figure l is a top plan of a brake 'gear being` removed from thecar.

view of the structure illustrated in Figure l e v l with the end portions' thereot in longitudinal The drawings are in a sense merely sche`- matic for the purpose ot illustrating; a typical or pret-erred embodiment of my invention, and in these dran*ingsv I have .em-

ployed similar reference characters to desigli'iateitlie same parts' wherever they "appear tlii'onghoi'it the several views.

uffi' .Yf'iib' i' n.; imen ion, as ui e undeistooc, is

capable ot-r use, with but slight change, to

divers types ot -car construction, and for convenience I have herein shown a carin which thetransverse endsill is of the channel type, which may be enamele, I-beam, 'of the like. i

with the web 5 yerticallydisposed and with the lower lianpge 6 'iroyecting horizontally in an outward direction from 'the cai'. rlhe brake operating` Vmast 7 is positioned outside the vvertical' plane ot the en'd ot the car and beyon'd".tlie flange 6 "of the sill, 'and secured to the inner face of the web 5 of the sill is a triangular zgusset or bracket consisting of a vertical 'plate 8 extending transverse to the sill with its vertical flange 9 secured to the i sill `web and'with its lower horizontal' flange l0 extending' longitudinally oiitthe car with its under surliace 'in the saine plane with and forming; a continuation of the lower surface ofthe flange G ot vthe sill. Y

The gearing' in this particular instance is illustrated in a conventional"manner and is preferably of thevtype fully illustrated and described inV United States Letters Patent No.`1,508,564, which was issued to' Fred Mathews' 'on "September 18th, 1921i, for a gearing, and consists briefly of driving and driven 'gear ymembers Aeach having concentric 'an'dheccentiic edge portions, the latter portions' being preferable obliquely disposed withrespectto 'the raxis of rotation otl the respective member.4 j The brake'pma-st 7 is operatively .connected to thel driving gear member and the driven gear member is mounted upon a spindle 11 the ends of which are supported in the housing.

lThe gear housing has bottom castings consisting of a horizontal plate 12, in which the lower end of the mast is preferably supported, and an arm 13 extends inwardly and is deflected downwardly from the plate to provide a support and journal for the spindle 11 and the driven gear member thereon, while the edges of said plate are provided with upstanding walls lil that overlap and ar walls 15 of the horizontal plate 16' of the top casting of the housing. The plate 16 has a neck 17 projecting inwardly longitudinally of the car and in alinement below the flange 10 of the gusset or bracket on the sill, and there is a transverse embossment 18 near the end of the neck to receive the upper end of the driven gear spindle 11. Beyond the embossment and transverse to the bore thereof is a hollow knuckle or eye 19, the purpose of which will hereinafter appear, and at the opposite or outer edge of the top casting are one or more pockets 20, (two of said pockets being illustrated) that open upon the sides of enlargements or blocks 'formed integral with and arise from the upper face of the plate (Fig. 2'). The structure heretofore described, consisting of the two-piece housing, and the driving and driven gear members are preferably standardized and assembled as a unit and kept in stock for divers types and constructions of cars with which the unit is to be equipped, but because of the fact that the underframe and bodies of the cars vary in design it is necessary to provide different means for attaching and mounting the gear unit to each type of' car and underframe or modified constructions thereof. To this end I have designed what may be termed an adapter which will now be described and which may be of divers shapes and dimensions so as to provide a ready means for installing the standardized gear unit upon different makes of cars or underframes.`

This ,adapterl7 preferably comprises a plate 2l of substantially rectangular shape that fits the-upper surface of plate 1G of the top casting and its edge adjacent to the pockets 2O is provided with lugs or shoes 22 that fit into said pockets and interlock therewith. A reduced neck 23 extends from the opposite edge of the adapter plate 21 and near its extremity which extends beyond the knuckle 19 is provided with an aperture 24: to receive or rivet 25 that also passes through the horizontal flange 10, of the gusset whereby the adapter is securely attached to the underframe. The sides ofthe neck 28 are provided with depending flanges 26 that eX- tend outside the adjacent portions of the neck 17 of the top casting, which flanges are secured to the vertical depending apertured in alinement with the bore of the knuckle 19 so that a removable pin 27 may be inserted through the knuckle and said apertures to connect the top casting to the adapter. For the purpose of reinforcing the structure against the longitudinal pull incident to the operation of the brake l have provided a bracing shoe in the form of a vertical plate or abutment 28 that engagesI the web 5 of the sill and is provided with reinforcing ribs 29 that slopes downwardly from the abutment towards the outer edge of the adapter 21. As will be observed in lt'gures 2 and a of the drawings the lower edges of the ribs 29 coliform substantially to Jthe adjacent surface ot' the lower flange 6 of the sill so that a ready fit is obtained,

n assembling the structure the adapter is usually mounted upon the sill or other adjacent portion of the car by inserting the plate 21 and the neck 2S under the sill and gusset until the abutment wall engages the web 5 of the sill to which it is secured by bolts 3G and the bolts are passed through the neck and secure the inner end of the adapter to the gusset. The gear unit may now be removably mounted by interlocking lugs 22 with the pockets 2O and then inserting the transverse pin 27 through the knuckle 19 and the apertures` in the depending walls 2G of the adapter neck. Should it be desired toV remove the gear unit in case of accident or replacement it is only necessary to knock out the pin 27, which permits the interlocking parts at the opposite end of the structure tobe disengaged.

lt will lbe understood from the foregoing that the adapter will have to be necessarily modified according to the type or construction at the end of the car being equipped, the essential feature of the adapter being that it is provided with means for readily and removably interlocking the same with the gear unit as well as with dependable means for connecting it to the car and bracing the structure against the pull instant to applying the brakes.

lVhat l claim is 1. The combination with a railway car underframe, of a gear unit for actuating the brake, an adapter structure secured to the underframe, and means on the unit and adapter to interlock the one with the other andpermit the unit to be readily removed from the car.

2.
