Application filed December 23, 1903. Serial No. 186,399.

car-trucks, and particularly to brake-rigging therefor.

The object of the invention is the provision of means for reducing` to a minimum the amount of movement necessary 'for applying the brake-shoes to the wheels.

With this and further objects in view the invention consists, in combination with a truck-trame and wheels supporting the same, of brake-shoes for said wheels and means for normally retaining said shoes in contact with 'the said wheels.

It further comprisesa car-truck, wheels supporting the same, brake-shoes for said wheels, and a cushion retaining said shoes normally in contact with said wheel.

It further consists in certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings. Figure 1 represents a view in side elevation of a cartruck and brake-rigging embodying the'features of the present invention. Fig. 2 represents a top plan view of the same, Fig. 3 represents a transverse vertical section taken on the plane of line 3 3 of Fig. 1. Fig. 4 represents an enlarged detail vertical section taken on the plane of line 4 4 of Fig. 2 looking in the direction of the arrow. Fig, 5 represents an enlarged detail view of the turnbuckle illustrated in longitudinal central section. Fig. 6 represents a transverse vertical section taken on the plane of line 6 6 of Fig. 5

and looking in the `direction of the arrow. Fig. 7 represents an enlarged detail central section taken through one of the journalboxes. Fig. 8 represents a transverse vcrtical section taken on the plane of line 8 8 of Fig. 7 and looking in the direction of the arrow. Fig. 9 represents an enlarged detail top plane view of one of the wearing-plates removed.

Itisswell known to thosefamiliar with the present art that when it is desired to apply brake-shoes to the wheels of a car the windingdrum of the brakedraft mechanism must be rotated sufficiently for compensating for all looseness of parts, and in addition foi taking up the distance which the wheels may move independently of their journalboxes after the application of the brakes due to such ap lication, and I contemplate reducing suc lost-motion to a minimum by the present improved structure, which, as seen in the accompanying drawings, comprises a turnbuckle, means for automat- '-ically rotating said buckle, and brakes actuated by said buckle in combination with a truck frame, wheels carried thereby, and means for preventing movement of said wheels independently of each other and inde endently of their journal-boxes.

eferring to the drawings, which illustrate one s ecilic embodiment of the above-mentione elements, 1 1 indicate side frames, each formed of a single piece of material bent into yoke shape, producing a pedestal 2 at each end. End frames 3 connect the ends of the side frames 1. Said side frames-are also connected intermediate their length by transversely-arranged transoms 4 4, between which transoms is sup c'ted a bolster 5 of any preferred type, Saul' bolster resting u on elliptic or other suitable springs 6, carrie by depending yoke-bars 7, connected to the transoms 4. The opposite ends of. each side frame l partially inclose a journal-box. 8, carried by one end of an axle 9, said axles 9 being provided with the usual supportingwheels 10 10. Each journal-box 8, as best seen in-Figs. 7, 8, and 9, incloses the journal 1 1 of axle 9, a bearing-block l2 being carried by said box and resting upon the journal 11, said block being formed concaved on its under surface for-conforming to the convexity of the journal 11. A rib 13 extends transversely across the central portion of the block 12 and at its ends terminating in segmental form, as at 14 14, extending beyond the longitudinal edges of said block for adapting said rib to t between the corner-.webs 15 15, carried by the walls of lbox 8. The distance between the upper ends of the Webs 15 is slightly less than the distance between the inner edges of the segmental portions 14, whereby when the block 12 is ositionedas indicated in Fig. 8 a space wil be left between the same and the upper wall or roof of the box 8. This p ositioning ofthe block has IOO IIO

the eiect of causing said block to assume its normal position after removal therefrom through jarring or constant movement of the arts.. It will be seen that if the journal 11 shouldbe caused 'to assume a slanting position relative to the box 8 the block 12 will be free to turn upon the seg nental portions 14, so as to maintain its perfect bearing on said journal without. altering the position of the box 8, and this is veryessential in the operation of the improved elements hereinafter set forth, as will later more fully appear.

Each box 8 carries on its outer side a pair I of vertical ilanges 16, between which flanges spective the link -22 and are arranged wearing-plates 17 17, engaging the respective pedestal 2 of the given side frame 1. The side of each box 8 opposite that carrying the ilanges 16 is provided with a laterally-projecting lug 18, Jforming the seat of a cushioning-spring 19', supporting the reend of the given side frame 1. An equalizer-bar 19 connects each pair oi boxes 8 at one side of the car-truck, each equalizerbar 19 consisting of parallel plates spaced apart with'their ends resting upon the uV per surface of the connected boxes 8, said p ates being bent downwardly just inside the boxes '8 to a plane below such boxes and extending horizontally'for a greater portion of the distance between the boxes. Thev downwardlyextending portions of said plates inclose the lugs 18 and are secured thereto by suitable boltsA 20, 'said lates being positioned outside the vertical .p ane of the given frame 1 for permitting vertical movement of the same between'the ends Vof the lates. Each bar 19 carries near each end thereof a bracket 21', secured between the plates of said'bar and inclined inwardly from the bar. Depending -from the upper free 'end of each bracket 21 is a link 22, pivotally connected to said bracket by means of a bolt 23, extending through the.

bracket and through said link, said bolt being surrounded b a coiled spring 24, disposed between'the ink 22 andthe nut 25 oi said be ad'usted against thespring 24 to any esired egree for producing suflicient frictional contact between the bolt 29, whereby sucient friction may be maintained between the link andthe ear 28 for retaining the link and ear in any given the bar 21 for retaining the said link in a givenv adjustedposition. A.l brake-beam 26 connects the link 22, carried 'erases adjusted position. Each bar 26 and 27 isv thereby supported and left free to swing laterally, and each of said bars carries at each end a brake-shoe 32, adapted to engage the respective wheel 10. Carried preferably centrally of the bar 27 is a link 33, extending horizontally from said bar and pivotally engaging a dead lever 34, connectedby a sui',- able yoke-35 to one of the transoms 4. The lower end of the lever 34 is pivotally engaged by one end of a turnbuckle, referred to generally by the numeral 36 and more speciiically hereinafter mentioned. The opposite end of the tur'nbuckle 36 pivotally engages the lower end of a live lever 37, pivotally connected to a link 38, carried by bar 26. 'The upper end of the lever 27 is engaged by any suitable draft-rod 39 or other operating means. A spring 40 is connected by a rod or other suitable means 41 with one of the transoms 4 and at the other end connected to the draft-rod 39 for eecting a lrelease of the operating elements (which may be of the common and well-known type) engaging the free end cit' lever 39.

As best seen in Figs. 5 and 6, the turnbuckle 36 consists of the threaded bars 42 and 43, having their outer ends connected to the lower ends of the levers 34 and 37, respectively. V./-i sleeve 44 is threaded onto the inner end of bar 42, threaded onto the end of bar 43. The sleeve F44 carries at its inner end a housing 46, completed by a disk 47, carried by sleeve 45, suitable bolts 48 48 being passedthrough'said housing 46 and disk 47 for securing the same together. A rod 49 extends into the bar 42 and is iixed therein against rotation, but lefty free to move longitudinally independently ci the bar 42 and projects Jfrom said bar into the housing 46. Rotation 'of bar 42 feeds the same into sleeve 44,- and such longitudinal and a similar sleeve 45 is IOO movement of said bar is independent of saidl j rod 49. A spring 5G is -fixed at one end of i said bar 49and is coiled about the same, and

at its outer end is connected with a pin 51, fixed transversely Vwithin the housing 46, whereby the housing 46 is subjected to a constant rotary pressure designed to unscrew the sleeves 44 and 45, which action'of the springs- 50 insures the spreading apart of the lower ends of levers 37 and 34, whereby the shoes Ill@ .32'will' necessarily be retained constantly in contact with the lwheels 10. An aperture 52 is preferably formed at any suitable point for admitting a lubricant into the housing 46V for insuring eectual action of the spring 50.

The turnbuckle may thus be automatically elongated and will be locked in any given position against compression byA the threaded connection between the sleeves 44 and 45 and the bars 42 and 43, whereby the brake-bars and shoes may be spread apart and locked in said spread cond' ably t eaded onto one bi: the bars 42 or 43 tion. A nut 53 is prefer-M outside of the sleeve thereof and is designed for jamming the sleeve for preventing rota` tion thereof when the spring 50. .becomes broken or otherwise inoperative.

In operation the shoes 32 are retained in contact with the wheels 10, but not with sufficient pressure for materially retarding 'the movement of such wheels, and the position of said shoes obviates the necessity for any ro great movement of the brake- beams 26 and 27 for the application of the brake-shoes, the wheels being prevented from givingiunder the pressure of the applied shoes by reason 'of the bearings employed, as illustrated, and dei 5 scribed with reference particularly to Figs. 7,

8, and 9. After the shoes have been ap lied y and itis desired to release the brake mec anism the release of the operating means connected with the rod 39 will permit the spring zo to'act; but vsaid spring only'afl'ects those elements connected with said rod V39, em-

ployed for actuating the same, (not illustrated,) the said spring,'of course, being incapable of materially affecting the levers 34 2 5 and 37 beyond throwing the latter back against the transom 4, Vwhich acts as a stop.

Although I' have disclosed in the drawings and described in detail the structure and o eration of my resent improved turnbuclife,

3o I wish it deci edly understood that I con;

Sider my invention more comprehensive than the mere employment of the novel form'of turnbuckle, which is only one embodiment 'of device capable of accomplishing the function 35 which the present improved structure is designed to attain. The novelty and breadth' of my invention will be appreciated when it is understood that any means which servesA to retain the brake-shoes spread apart after Vio such shoes have been thus spread and pre- V. venting the shoes from other or leaving the wheels is comprehended within the scope and spirit of my conce tion.

The prime object of the invention is t e re- 4 5 tention of the brake-shoes against the wheels b r tne'provision of means for takin up the lwear on said shoes and retaining te shoes against the wheels after the same have been applied by the' operation of the brake-apply- So ing means.

.For a more comprehensive understanding of the 'invention the operation of the structure disclosed'vs'hould befully understood and the functions of the springs 24 and 30 appre- 5-5 ciatedt The springs 24 and V3() produce such frictional engagement between the parts as .to sustain the shoes and beams in their given positions for ap lication thereof at least for a suilicient peri'o for permitting even a very 6o weak spring 50 to actuate the parts of the tiirnbuckle for spreading the same suHiciently for taking up any wear upon the break-slioes,f,thus `assuring the constant application ofi'the shoes .to the wheels, as each time said s'lioesiaze-applied for stopping the wheels. Vbetween theaXle-journals 11 and the eqiial- 8o approaching each rotation of the wheels the friction occasioned by the 'springs 24 andf() will be sufficient to give the turnzliuckle an opportunity for actuation; furthef, itis of importance that the brake-beams should be suspended from the 7o equalizer-bars for the reason that by thus sustaining said beams vertical movement of the brake-shoes with reference to the wheels is obviated. In the ordinary construction, where the shoes are su ported from the truck- 7 5 frame, the springs undhr the frame allow vertical movement of the shoes, which prevents a constant close iit between the shoes and The elimination' of all lost motion izer-bars 19 and the supporting of the brakeshoes directly by the equalizer-bars prevents movement of the shoes with lrespect to the wheels, so that when said shoes have been-a plied to the wheels by operation of the bra e mechanism any automaticallyf adjusting means, such as the turnbuckle, might be provided for taking up the slackl due to Wearing away of the shoes.

The action of the parts is as follows: The 96 shoes are first forced apart against the wheels by longitudinal forward movement of the rod 39, and when the brake is released the spring 40 forces the live lever-against the transom, the friction of springs 24 and 30 preventing 95` movement of the shoes 32 toward each other, (or brake- beams 26 and 27 toward each other,) the movement of the live lever permitting the turnbuckle to-le'ngthen itself for automatically taking up the slack between the shoes and the wheels resulting from wear. While I have disclosed in the drawings and specifically described an improved form lof truck involving equalizer-springs arranged between divide e ualizer-bars and have also disclosed improve j ournal-bearings, I make no claim to the same in this application, but hereby expressly reserve my right to these inventions and propose to embody the same in the form of divisional applications. x The feature of the equalizer-springs aria'n ed between divided equalizer-bars is cov- 'erecIfby claims in my divisional application, Serial No. 223,992, filed Se tember 10, 1904.
