This invention relates ,to improvements in hand brakes.

One object of the invention is to provide ar simple and efficient hand brake for railway 5 cars, which is particularly adaptedfon use on flat and logging cars,andwherein.the

brake staff may be swung yfrom verticalto horizontal position at theside' ofthe car so as to clear the projecting'portions of lumber, logs, or the. like with which the carisloaded.

A more specific object of the invention is to provide a device of the characterindicated including a chain windingdrfum carrying a driven means, anda.brakestaffy carryinga driving means adapted toengage the driven means, `whereinthe drnm is mountedfor rotation about a fixed aXis,th e stai is` mounted for swinging movement from'a vertical to a horizontal position, andl the driving means is adapted tooperatively engage the driven means in eitherof said positionswithequal efliciency.

Other objects and advantages oft-he invention will more clearly appear, rorntheder scription and claimshereinafter following.

In the drawing forming `a part of this specification, Figure 1 isfanfend. elevational view of a portion of a flat car, showingrmy improvements in connection therewith., Figvy ure 2 is a vertical, sectional view corresponding .substantially tothe line=22 of Figure 1, the rotary parts. being shownL asVv moved through an arcof 90"= from, the-position shownjinFigure 1. Figure 3, is a vertical, sectionall view corresponding, substantially to the line 3 3 0f Figure 2. And Figure is a horizontal, sectional vview correspondingsubstantially to the line 4 4 of Vliligure 3.

VIn said drawing, 10 indicates the, usual floor of the Hat car, l1 the end sill to which is attached theY brakemanls platform 12, and 131 one of the stake receivingsockets which are ixedto the sides of the car. v

The improved brake mechanism, vas shown, comprises, broadly, a brake staff A; a hand wheel B; a combined drvinggear andbearingY member C; a brake drum, D; afloeking collar E; a pivoted support F; and a pair offbrackets G andH. g

The 'drum D isin the form oa two part hollow, cylindrical sleeve, the. sleeve being divided engiudinaiiy, tiresectiens 13 'ofthe sleeve `being exact counter parts. The sleeve' D;is mounted for rotation about an ,axisldilse posed in a plane parallel to the end of the.

carjandis arranged atan angle of 4:50 tothe; vertical. Thelower end of the drum D is re duced, as indicated at; 14, to "provide a bearing portion journaled, in thelowerl end of the bracket 15 projecting downwardly from the bottom of the car and Xed to the end sillfll` byrivetsorany other suitable fas# tenin'g, devices. v'The bearing portion 14 gis also divided longitudinallyeach part ofthe same being formedI integral; with fthe'. correspending section 13 of thedrum, The upper end portion of the ,sleeveVK forming thedrum D; lsjournaled in val bearing meinber- 16 formed on the outer endof an arm IZ'lat- 1 erally projecting' from they brackety-f-G 'securedto lthe end sill 11 by rivets or any other suitablev means; At, its;t 1pperend,;the drum D yis provided witha beveledringfgear 18, .the gear, 18. being. cmnjposedy of.V two Sections each of which is` `formed integral with the corr esp onding` section 13 of the drum.I The f vupper end, ofthe drum D is also provided ing formed.in,eachlsection,13;I Theisocketl` 1 9 is preferably Aet vSpherical shape with the center thereofA in alillelflflellt` with the-taxis,v of the drum.

square' portion 22 of thestaff A, to 'which it is rigidly secured `as by a" pin Qilextencling transversely through the Castille andi the of the casting@ has a Cylindrical 'ex'terir and is jounaled 'in a horizontallyarend icc Square Partien" 0f the Stait; Thefapperrid rbracket F, which is pivot-ally mounted on the bracket Gr, the latter being provided with a boss 26 adapted to receive the trunnion 27 extending laterally from the former and held in position by a cotter pin 28. Immediately below the cylindrical portion of the casting Vwardly. The conical portion of the casting C is formed with'a series of peripheral teeth 31 thereby presenting a bevel gear adapted to Vcoact with the teeth ot thebeveled ring gear 18.

The stai A is also provided with a-ratchet wheel 32 of well-known construction mountedfon the square portion of the former for rotationV therewithv and is adapted to bear on the upper surface of the plate 25. Av

' lockingfdog 33, adapted to coact with the ratchet wheel 32, is pivotally mounted on the plate by the bolt 34.

ToV hold the stan? in vertical position the` following means is provided. Y The bracket Y G is formed with an upper, laterally eXtendf ing, arm 35 terminating in a hook shaped portion 36 providing a socket having an upstanding curvedflange 37 adapted to engage within an annular flange 38 downwardlyeX- tending from the collar E slidably mounted for vertical movementon the staff A. It will be evident that when the flange of the collar Y is engaged over the flange 37 of the arm 35, the stall will be positively held in its vertical position. To Vdisengage the staff from the socket of the bracketv 35, the, collar E is moved upwardly on the staff Athereby disf engaging the same from theflange 37 whereupon the staff may be swung downwardly to the horizontal position shown in dotted lines `in Figures 1 and 3.

lTo retain thestai 'A in the horizontal poel s ition, the bracket H is provided, the same being `in the form of a U-shaped hook memberrigidly secured to the end sill'11` by rivets. The short arm oi" the Uportion of the bracket H is provided with a spring clip L10 adaptedV to work in a slot in the arm ofv the brackety and spring into position over the stall when the same rests within the hook Yso portion of the bracket. To permit the brake staff A to be swung into position, the brakemans platform 12 is pivotally mounted so as to swing upwardly, thezsame being supported bya pair of brackets 41 iiXed to the end sill 11 by rivets and straps 42 secured to the lower side of the platform and pivotally connected with the brackets 41.

In assembling the device, the spherical end n 19 ofthe. combined bearing and gear C is first engaged within the socket portion of one of the sections 13 of the brake 'drum D. The opposite section 13 is then secured in-position by the rivets 120 and the eye-bolt 21 thereby retaining the spherical end permanently wit-hin the socket. The pivoted bracket F is next assembled with the combined gear and bearing member C by inserting the cylindricalbearing portion of the latter within Vthe opening providedin the plate. The stan;1 A, after having the ratchet and collar E yplaced thereon, is then assembled with the member C. i Y y' The operation ofthe device is as follows. Vhen the brake staii is in the full line position shown in the drawing, that is, when the same is disposed in'vertical position, rotation of the hand wheelwill efliect rotation of theY chain winding drum in either direction through the inter-engaging gears C and 187 in a wellknown manner. WV hen itis desired to operate the brakes from the side of lthe car, the iange of the collarE is disengaged f from the flange 37 of the bracket 35 andV the statt A swung to the .position shown in dot-ted lines in Figures 1 and3, thebrake'- mans platform 12 being first swung upwardly out of lthel way. vlt willpbe evident d that in swinging the stati' A from the vertical tothe horizontal position, the gear teeth. 31Y will first be disengaged tromthe upper side of the ring gear 18 and reengaged atthe lower side thereof when the stafi'reac-hes the horizontal position.'y In the swinging movement ot the stati, the pivoted bracket F together with the locking dog and ratchetwheel will be Acarried therewith, as clearly shown in Figure 1. It will be evident that rotation of the locking dog around the axis'of the stafi' is efiectively prevented by n jects above the level of the floor so all posi sibility of interference with projecting material is absolutely eliminated. Furthermore, the hand wheel in fthe Vlowered position of the staff is ata convenient and accessible vpoint forthe brakeman, whether he be `running along the ground or on the usual step. I have herein shown and described .what
