(Cl. 18S-212) The invention relates to a railway'truck and more particularly to a brake rigging and brake beam support therefor.

An object of the invention is the provision, in a railway truck, of a relatively movable side frame and journal box with a brake beam support carried by the journal' box.

Another object .of the invention is the provision, ina railway truck, of a side frame and journal box movable vertically relative to one another with a brake beam support for a clasp brake arrangement connected by the journal box so that the brake beams will be maintained in fixed relation with an associated wheel irrespective of the service movements of the side frame.

A further object of the invention is the provision, in a railway truck, of a relatively movable side frame and journal box with a unit casting forming a brake beam support which is pin connected to the journal box and arranged to guide brake beams to and away from a wheel in substantial alignment with the axisl of a Yjournal associated with the journal box.

An added object of the invention is the provision, in a railway truck, of a side frame and journal box having a brake beam support removably secured to the journal box in subjacent relation thereto and enclosed guideways in the brake beam support for the accommodation of slidably associated brake beams.

These and other objects of the invention will become apparent from the succeeding description considered together with the accompanying drawingswhich disclose an exemplified form of the invention and wherein:

Figure 1 is a partial front elevational view and a partial vertical sectional view of a portion of a railway truck embodying a form of the present invention.

Figure 2 is a partial plan and partial horizontal sectional view taken along the lines 2--2 of Figure 1, looking in the direction of the arrows.

Figure 3 is an enlarged transverse sectional view taken along the lines 3-3 of Figure 1, looking in the direction of the arrows.

Figure 4 is an enlarged transverse sectional view taken along the lines 4-4 of Figure 1, looking in the direction of the arrows.

Figure 5 is an enlarged transverse sectional view taken along the lines 5 5 of Figure l, looking in the direction of the arrows.

Referring now in detail to the drawings Wherein like reference characters designate like parts, the numeral I is employed to indicate in a general manner a railway truck only a portion of which is illustrated. As will be clearly understood, the disclosure of Figure l is only a portion of a truck with which the present invention` may be employed, and for a construction which may constitute the undisclosed portion of the truck reference is made to patents of the type granted to Donald S. Barrows on October 11, 1938, numbered 2,132,382. The railway truck includes a side frame 2, only an extremity of one being illustrated, which has adjacent an;end thereof a laterally and downwardly opening pocket 3 for the accommodation of a'journal box 4. Inl the disclosed constructionthe side frame is arranged and constructed so as to be capable of moving vertically relative "to the journal box, and in order to obtain a flexible journal box and side frame' connection the journal box is provided with longitudinally extend'- ing brackets or shelves 5 adjacentthe lower vextremity thereof to form rests for spring means of any nature and characterized inthe instant structure bythe coilsprings 6) The springs, as will be understood, have their upper extremities associated with suitable spring seats (not shown) on the side frame and are, therefore, arranged' to transmit loads from the side frame to the` journal box. Y

Housed within the journal box is an extremity 1 of an axle 8 which extends betweenv aligned journal boxes of the railway truck. Suitable bearing means (not shown)' is interposed between the axle extremity and a roof 9 ofthe journal box so as to conduct forces or loads from the journal box to the axle and facilitate a free rotative movement of the axle relative to the journal box. Fixed on the axle, inwardly of the truck from the side frame,'is a wheel I0 in close proximity to the journal box.

Each journfn box is provided with a pendant, bearing or hanger II desirably formed or cast integrally therewith to depend below aY bottomA wall I2 of the journal box( The hangers, which may, if desired, be formed as separate elements and secured to the brackets in any approved manner, are spaced longitudinally of the truck on` either side of the transverse center line of the journal box, and each comprises transversely spacedv anges I3 merging into inturned'webs I4. Depending from the inner or'free extremities of the webs are vertical legs I 5 which are joined by a lower'or bottom wall I6 extending beyond the horizontal limits of the legs for a predetermined distance, such as at I1, to form outwardly or oppositely facing reliefs or recesses I8, the" purpose of which will Vbe hereinafter explained'. 1

Since brake shoes 2|), secured to the brake beams.l-

and forming parts of the braking mechanism, are

in longitudinal alignment with and arrangedtecontact the Wheels in order. Vto control. the, progress of the truck or retard. thespeed thereof and the brake shoes are moved in a path-'chef extended plane of which is in alignment with an axis 2| of the axle or substantially therewith and forms an oblique angle with a horizontal plane passing through the axis 2|, any vertical movementi` between the side frame and'- jourlnalbox will? create abnormal* forces in the-braking: mechanism. and! particularly the portions thereof which' form A connectionsl tol the side fi-ame.

In order to prevent oreliminate the creation of the' above referred? to; abnormal' forces the present' invention contemplates suspending the braking; mechanism from the jouinal boxv` so that irrespective of' anyA possiblef relative ver-tical; service movements of.'A the journal box and sidefran'ler theibrakeshoes will; at-` alltimes, be mountedrin'. a iixedor constant relationship with theiwh'eels".v Thepresentiembodimentlof the invention includes an? arrangement; adapted tol-accommodate longitudinally spaced! brake beams associated with each wheeland of an order or, classrcommnnlycalled clasp brakes; .but it willbe definitely understood that, ifiV desired; one, of the brake: beams; and; its: immediately related'.v sup-` porting 'structure may be.. eliminated' toi thereby. render.l the; arrangement; suitable for.l the: positioning. ofV a.r single brake: beam adjacenteachv Wheel;` Aszan exemplicationot apreferred arrangement; there; is provided a" unitcast or integral brakebeam'supportorirame. 22' positioned'- in'the'mainin subjacent relation: to thejournal box and comprising an intermediate portion',.sill. or :foundation member, 2 3 formed transversely spaced,A vertically disposedV sida' walls.: 24;' joined adjacent their lower extremities, by'a;horizontal: Connecting .the other or'upper extremities of 1thefside wallsgis'a. top' wall 26 to present asill offv box; section throughout an appreciable extenti thereof', as. mostclearlyillustrated in Figuresf2v and 3-ofthe1 drawings. The'top'wallhas longitudinally spaced openings 21: which-y in their. immediate; vicinity., change the cross sect-ion of the'fsilltoa U-shape; opening upwardly ortoward the journal boxY to permit the introduction of the; hangers to: the interior of thesupport. f Y

In* order to form a connect-ion between the: support: and'- journal boxthe sill or.- foundation' member side walls a-re provided with: alignedv aperturesy 28. and 28? which'V a-relongitudinally spaced andr coaxially disposed with respect toapertures 29 formed in the transversely spaced anges- |-3-ofthe-hangers; Extendingthrough or occupying relatedvaperturesis arplurality of pins, keys, rods or shafts-29a of adiameter to fit nea-trly.A the accommodating aperturesso f asto' iirmlyor iixedly secure the support-tothehangers-and' eliminateany play'or lost'V motion therebetween; Because off the closeV proximity oftha siljl. tev the Wheel itfvis preferred to-AerrlployT aheadless Ykey or bolt so that no part will project beyond the limits of the support toward the movable wheel. This, therefore, necessitates the provision of restricting shoulders 30 in the apertures 23 so thatthe pins may be arrested upon any tendency thereof to shift from a predetermined position outwardly of the sill toward the wheel. The side Wall of the intermediate portion carrying the apertures 28e has formed thereon cup or cap-shaped clips 3| apertured as at 32 Vto permit the insertion of the pins in a support-hangers interlocking position. The formation of the clips on the support side wall presents lgrooves or slots 33 directed longitudinally. of the.. side frame for the accommodationpipin. arresting plates 34 bent U-shaped tov-be therebyfinterlocked with the clips. In this manner the plates are positioned in the path of the-pins and are arranged to arrest an unwarranted or accidental displacement thereof in a direction outwardly of the truck.

As a' precautionary measure there has beenincorporated into the present structure mean-s which may, at some future time, be brought intok usetoprevent'the brake beam and support thereforv from. falling upon the rails to.` cause derailment ofthe-:trucll: Toward the` accomplishment of the above, longitudinally spaced auxiliary standards or inner posts: 35` are formed in each support intermediate section' upstanding from thebottorn Wall thereof; The freeextremitiesl of the posts. as: well as the outermost.: side WallA 'of each' supportV are-provided; with lips or fingers: 36 directedtowarolfA one. anotherV and extending' into thefreliefs or rests I8'. Thengers are normally` spaced from the; adjacent' portions` of the. asso-- ciatedi pendants andl in overlying relation with respect tothe bottom` wall` portionsA |51' 'so/that, uponan unwarranted orv accidental downward movement: ofY the support. from.. the illustrated position`A the` support will be simpended by: the portions |11 to prevent the, brakefbernnY andi theV support from reaching a position or fallingv befneath the wheels.

The bottom, top-and sidewalls 'merge adjacent the-extremitiesoffthe brake beam. support to'forrrr oppositely disposed or directed; inclined or; up- Wardly dii/erging; arms 31 to Vcontinuetoy thehorizzontal or longitudinalV limits of the support: as' shelves` or rests- 35i-ot appreciable area tothereby form lower or bearing plates or rails for extremities-39 of the brake'- beams |9. Upstanding-.fiom andsubstantially-normal to `each shelf or rail' are spacedY end stakes or langes'llilwhich are joined at their upper extremities by'a top'or upper plate 4| disposed parallel to' the related.v rest. The; shelf, upper plate and' end stakes denne a' guideway, stirrup-or confined area therebetween' to accommodate a brakebeam extremity and guide the beam throughout the entire range of service" movements thereof. A- substantially continuous Iibf 43 outstands'from the end stakes and. topplate of each brake-beamsupport extremity to reinforce thefrela-tedstakes and plates against lfo rces to which they willzbe subjected during service. The shelves or bra-ke beambea-ring-rails are provided with depending or gusset-shaped ribs 44 whichf'form continuations ofthe ribs- 43- to extend along the bottom wall portions-of the-adjacent' arms and form, in effect, knee braces to-rigidify the support.: The rests-or shelves-and upper plate are disposed at an oblique angleto'the horizontal, and accordingly'sincethe bra-ke sbeam extremities are-arranged to` slidablyr engage the former. when the-brakei'shoes are freeof the wheelsfa-ndither' of these. members,v depending upon the direction` of the rotation of the wheels during a brake application, the brake beams are guided in paths designated by the diagrammatic lines A-A'substantially in alignment with the axis of the interposed axle. It will, therefore, be noted that irrespective of vertical service ymovements of the journal box and side frame the brake beams will, at all times, insofar as theii` paths of travel are concerned remain fixed with respect to the wheel.

From the foregoing it will be observed that various changes and alterations may be made to the illustrated and described structure of this invention 4Without departing from within the spirit and scope of the appended claims.
