BRAKE-GEAR MOUNTING.

Application led April 11,

lVIy invention relates to mountings for the gear mechanism, employed in operating the hand brakes of railway cars, whereby the gear mechanism is suitably supported from the end sill members of the car or its underframe; the invention at the same time involving a construction which will enable the gear mechanism to be readily removed and replaced, should occasion require without the necessity of removing the entire mounting or housing from the end sill member-of the car.

The objects and advantages of my invention will be readily comprehended from the detailed descriptionr of the accompanying drawings wherein- Figure 1 is an clevation'of my improved mounting with the gear mechanism therein and showing portions of the brake-staif and end sill of the car.

Figure 2 is a plan view with portions of the floor support and reenforcing bar of the car frame broken away; lwhile the brake-staff is shown in section.

Figure 3 is a side sectional elevation.

Figure 4 is an elevation of the inner end or sid-e of the mounting with portions shown in vertical section. f

Figure 5 is a perspective view of the top clement or member of the housing.`

Figure 6 is a perspective view of a bracket member employed on the inner side of the end sill. Y

My invention comprises a mounting more especially intended to be secured to the end sill of a car, the sill being in the nature of a channel beam 10, see Figure 3, wherein the top Vand bottom flanges of the beam are di`sposed outwardly, relative to the 'car end, while the vertical web portion on the inner side is provided with an angle bar 11, which is frequently employed for supporting a portion of the car floor while at the same time acting as a stiener for the end sill. The

' angle bar is usually riveted to the web of` 1927. Serial No. 182,742.

above the plane of the flat portion 15 and connected bythe upwardly sloping wall 16; the plate being preferably reenforced by the sloping ribs 17 extending transversely of the Hat portion 15 and the intermediate portion 16 and terminating adjacent to the inner longitudinaledge of the flat portion 14. The top plate is further reenforced by roviding the depending side portions or anges 18 which preferably extend about the four sides of the plate; with'the flanges 18 at opposite sides increasing in depth toward the forward outer end of the plate to provide the de'- pending lobe portions 19.

The bottom member 13 consists of a substantially rectangular flat portion V20 corresponding iulength and width with the flat portion 15 of the top plate 12. The opposite ends of the portion 20 terminate in upwardly disposed end Walls or lobes 21 adapted to have partial lapping relation with Vthe lobes or ears 19 of the top plate. In the particular exemplification, the

end walls

21, 21 are shown lapping the inside of the lobes or extensions 19 of the top plate, to which they are suitably secured, preferably by means of rivets 22 seeFigures 3 and 4.-

The bottom plate 13 intermediate of its ends is provided with an inwardly extending arm 23 which is shown offset downwardly, in

order to position Vthe driven mechanism in the desired horizontal plane, and made tapering toward its ends. The free end` of the arm 23 isV therefore disposed in a plane beneath that of therflat portion 2() ofthe bottom member and provided with a flat upper surface as shown at 24 vin Figure In order to provide sufficient strength the arm 23 is also shown provided with the longitudinally disposed reenforcing ribs 25, thus Vproviding the bottom plate wit-h proper strength to support the gear mechanism.

The top and bottom members at their forward outer ends are `both apertured to receive the brake-staff- 26 to which a `drive pinion of any suitable construction, as shown` for exam-ple at 27, issecured intermediate of `the surface 15 of the top plate and they surface 20, ofthe bottom plate. The aperture in the bottom plate is somewhat smaller in Vdiameter than the diameter of the main por# tionv of the brake-staff to merely receive the reduced lower end'of the brake-staff. The

bottom plate about the brake-staff receiving vaperture lis preferably provided with Van encircling boss as at 2S on which thei main portion of the brake-staff rests.

The inner end of the arm 23 of the bottom plate supports the Adriven gear 29 and the spool or drum 30, the latter being intended toreceive the usual chain connected with the brake mechanism. The bottom plate with its arm 23 is of length somewhat greater than the length of the top plate and therefore extendsinward of the end silllO of the car with the result that-the journal of the driven elements of the Vgear mechanism is Y located in a verticaljplane rearward of the face of the end sill.

verticalplane of the end sillas shown in FigureV 3; while the top plate l2 is intended tobe securedat its inner end 11i tothe lower iiange of the end sill,by means of rivets as shown at 3l, or otherwise, andis notV intended to extend beyond the inner vertical through, as shown in Figure 4. The bolt 32 is shown preferably providedvwith a ferrule or spacing'collar 35vresting'at` its upper end in the ,countersunk portion vabout the bolt# receiving,aperture in plate 33, while its ylower l endrests in a Asimilar countersunk portion Vthe oilchannels'. 38. Y A In order to properly:` support the inner end 1 of the gear mechanism and to reenforce' the about the bolt-receiving Yopening in the end ofarm23 of the bottom plate.

' .It is apparentthatV with the plate 38 1 place. and the nut 36 secured tothe bolt 32,

the driven elements will bemaintained in place Vduring shipment of the mounting and the Vgear mechanism, namely while .the mounting -isstill unattached to a car. y In the exemplification as more clearly shown iirFigure 4i, the driven gear 29 on its lower side-is shown provided with an elongated hub 37 having a reduced end lwhich lits into thespool 30; said lreduced end and' the opening in the spool ,being of no1'1ci1'-l cular formation in order. to induce rotation` of thespool Awith the driven gear 29. The

openingthroughwthe lhub 87 of the driven gear andthe opening through the spool 30 are shown; longitudinally grooved to provide mountingfagainst the inward pulls 01 st-rains l' encountered during brake operation, I provide a bracketelement 39.j This-bracket elem'ent'is preferably of the rectangular box-V like vformation shown, ywith its bottom 4:0 of

vslightly greater width than the top Wall 4l; i While the Vend wallsl 42 are therefore alsoV slightly wider atthe'lower ends, thus providing the olf-,set shownat 43 Vin order'tliat the upper end ofA the bracket element 39 may fit against the vertical leg or portion ofthe angle bar 11 while Vthe lowtn' end thereof may extend beneath the angle bar and abut against the vertical face of the end sill 10,

nas shownin'Figure IThe-bracketelement 39e-fertile purpose ofV giving it sufficient strength, is shown preferably provided with the transverse webse/l disposed between the top face ilvand the bottom face 40. The side of tliebi'acket element 39 which is to be disposed againstthc vanglebar l1 and end Vsill lOis provided with a side wall l5 having the shoulder Li3 likeitlieend walls 4t2; and this side wall i5 is provided with suitable apertures -to receive' the; attachingmeans or rivets 46 whereby the brackeneleinent 39de riveted to the vertical portion of'the angle bar ll and thevertical web of the en d'sill 110, see Figures and il;v while the topwallv 1li of the bracket element isA shown provided with an aperturepat i7 whiclienables the bracket member to be riveted or otherwise secured to the horizontal'pertion of tlieangle bar l1 as by means of the rivet 48, see Figures 3 and Ll. l

In applying the mounting to'ihecar,Y the plate 33, which h oldst-lie ournal pin or bolt 32 of thc'driven mechanism in place', is riveted to the'botto'm face 40 `thegbracket element 39; the bot-tom face Li() of thebracket V element being yprovided with rivet or bolt-- receiving openings as shown at 49 adapted toireceive ,the rivets 50, shown in Figure-l. The bottom wall l() of the .bracket element is also shown provided with the non-circular or rectangular opening 5l to receive the head 3 4- of the journal pin or 32V and prevent rotation of the 'pini tpis vevidentfrom Lthis construction .thateven ifithe nut 36 ofthe bolt should accidentallybecome removed the journal pin or bolt 32 .will lbe held in place by the plate Y lith my improved construction it is apparent that the lgear mechanismamay be readily vremoved :without dismantling the mounting-- beyond `disconnecting plate from V the bracketelement 39 whiclrmerely involves the removal of the yrivets 50. At

the Ysame time the rigid bracket element 39, 1n conjunction with the bearing plate 33,

Vwill iirmlyhold the mounting against the inward pulls ,and 'strains encountered during brake-applying operation.- y

The construction as disclosed in the drawings .isbelieved to be the .best embodiment yofthe invention, but modiiicationsmay'be made in certain dieta-ilsWithout,Y however, departing from thespirit-of theinvention.
