Specification of Lottery-Patent. Application filed July 15, 1968. Serial No. $48,128.

Patented Aug. 8, 1909 To all whom it may concern:

B e it'known that I, Cannes M. Evans, acitizen ofthe United States of: America, and resident of Springfield, in the county ofjHampden and State of= Massachusetts,

adapted in the making up of the car body to receiveconnection with members thereofof the bols ter, the floor sills, the platform: cross beamand the draw bar.

The improvements also especially pertain to constructions and combinationsbi parts for theconnection of the head frame with the-bolster.

Theinvention is illustrated in theaccompanyiugdra wings in which Figure 1 is aplan view showingthehead frame in full lines and indicating by broken linesvthe bolster, the floor sills, the draw bar and the horizontal transverse member for constituting the forward end support for the platform. Fig. 2 is avertical longitudinal section ou line 2-2, Fig. '1. Figs. 3, 4, 5 and l6 are cross sectional views on a :larger scale as taken respectively on thedines 33, 4-4, 5*-5, and-66, Figs. 1 and2.

In the'drawi-ngs, A represents the integrally cast structure for the end portion of the bottomof iii-railway car body and which structure is'herein forbrevit termed the head frame 'The frame while susceptible of v'ariedwdesi 11 may practicably-comprise members which will be described in detail find-in their relations one to another as fol lows a '10,' 10, indicates sep rated parallel horimute! and longitudina 1y ran ing bars outsicleof which, in separation-t erefrom and inparallclism therewith, are similar longitudinally/ranging bars 12, these-all beingeof T-sha'pc' in cross section forwerdly united by "ppm-and lower transverse cross tie bars 13 and 14, intermediately traversed and also united by the floor sill attachment girder a and rearwardly united, at u' compniratively short distance forward of the rear-ends of the bars 10, 10,.by'the cross bar 144; and the oblique, horizontallydis posed webs or brace bars 15, 15, are made 'inte rally with-and unite the reartends of the. are 10, 10, to the rear ends of the shorter bars 12, 12, and the opposite outer ends of fthe floor sill girder, the intersection 'of said oblique brace bars 15 with the bars 10, 10 being near the junctions with the latter w ltegrallyformed horizontally cross bar 14!.

The floor sill girder is approximately of gal-1 extent, transversely equal to the full %width of the head frame, and being extended 1 at-either side .beyond the bars 10 and-12-- and stands, as shown in Fig. 2, abovethe plane of the upper surfaces o,f'ths-bars10 and 12 and has cheek flangesorlwbs'18,18, invertical and longitudinally extending'par allel planes for the connections therewith, bybolting or riveting, of the carbodysillsrepresented by the dotted lines 511:. v. 1

' The, bolster B comprises at its for'ward end a cross beam or bar I) l1aving' 'tlirougli the webbed portion of its channel iron formation two= T-sl'mped apertures e through which the rear extremities of theT- shaped bars 10, 10, of the head frame may he slid or fitted'to receive at their portions protruding rearwardly beyond the cross member d of the bolster, detachable engagement corresponding to the width of the car b dy;

means for unit-in .the head fname and 'bo1- of their disster and yet readr y permitting may become connection as occasion therefo desirable. The means of the connection or engagement'justreferred to-is repress ted in igs. 1,2, 3 and 4 and consists of bio ks or plates 7 f which lie along and a ainst the outer faces of the median mem ers of the T shaped head frame bars 10, 10, which are provided with square apertures 20, within which apertures in the bars 10, square dowels,-integrally formed with and tending transverselyfrom the faces of the blocks f; have closelyfitting engagements. Theforward ends of the blocks are m abutment a' ainst the rear face of the web of the bolster cam b for an increase in thestabilit of the construction, and-the blocks-or p ates: are confined against gmcl alongtide structures.

'wardly, and receive, rearwardl side of the line 0 bolts 36.

the bars 10, 10, by the bolts 23. The connection or engagement blocks 7 f, confined on the sides of the head frame bars 10, 10, engaged by their forward ends with the web of the bolster beam, engaged by their upper edges with the flanges 0 the bars 10 and having the s 'uare dowel and socket enga ements with t e bars 10 constitute means 'or reliably, stably and rigidly connecting the head frame and bolster with the capability, as hereinabove indicated, of conveniently connecting and, disconnecting the The head frame com rises structural features yet to be descri ed for the dis osition therein and engagement therewitli'of the draw bar buffer plates or connections.

The parallel se )arated bars 10, 10, suitably forward of the bolster connections are downwardly widened or extended as shown at 1-0, 10 Fi s. 2, 5, and 6, and they are made with inward y opening okets or channels 25, 25, as produced b t e" upper and lower flanges 26, and 27. hes pockets or channels have forward end wall abutments 28; and, as well a so positely sidewise opening inwardly, these 0 annels endwise open rearlocated therein, at a somewhat extreme istance to the rear of the abutments 28 (which are preferably inte ral with the parts 10', 26 and .27) remove le abntments 30, 30, which are constructed in the form of cored-out bloelcsprovided with dowels, or outwardly projecting studs 33, which engage, with close tits, in sockets or mortises 34 in the portions 10*, 10, which constitute the ver tical walls of the longitudinal channels.

"ll-ieabutincnt members an, 30, are secured in the channels or 'iockets 25, 25, at either the draw bar by" the The drawbar- C centrally horizontally and longitudinally "disposed under the head frame and having its rear attenuated extremity between the inwardly openin mouths of the channels 25, 25, 1s extende throu h the apertured separated and for= ward und'rearwardly located butler plates 2', z', e side ears or extensions 37, .57 of which laterally extend for sliding fits in the o'ppositelf located pockets 25, 25, the forha or plate having the forward-surrearward ly contacts b its extensions against the forward ends of t eremova-ble abutments 30, 30-. The' draw bar spring I: is in compression as usual between the buffer plates 2' i, and the nut m forms the means of engagement, as common, between the rear end pr shank of the draw liar and the'rearward one of the buffer plates. When it is desired to disconnect or take outthe draw bar butter yond the main platcs, --the draw bar being disconnected therefrom, the bolts 36 are removed, the abutment blocks 30, 30 are ,i'orced slightly transversely inwardly to disengage their dowels 33 from within the socket 34, and then the abutment blocks are slid longitudinally rearwardly along, and out from the rear open ends of the pockets, thereby leaving no impediment to the rearward sliding, for removal of either or both of the buffer plates.

The draw-bar mechanism here shown and above described constitutes the subject matter of my divisional application for patent, Serial N 0. 476,977.

I claim:

1. A head -frame consisting of a single casting integrally comprising an inwardly located pair of separated parallel, longitudinally ran ing bars, and a pair of parallel longitudinally ranging bars outside of and separated from said first named pair of bars, a transverse tie member connecting all of said bars at their forward portionsfan inter- !!lttdiately located floor sill attachment girder extending, transversely across, uniting and projecting oppositely outwardly beyond all of s id longitudinal bars, members transs vers uniting the inner pair of the longitudinal bars at their rear portions, and members diagonally uniting the rear portion of both pairs of the longitudinal bars with each other and withthe outer end portions of the irder.-

2. Tie combination with a head framd eoniprisin separate longitudinal bars, a, pair of w iich are rearwardl extended beyond the main portion of tie frame, of a. bolster comprising a cross beam havin "separated azpertures therethrou h, througiand.

rearwar ly beyond which he rear extremi ties of: said frame bars extend, and blocks securedouths sides of the frame bar extremities and havili engagements with the, cross beam of the b0 ster. V 3. The combination with a head frame comprisin separate longitudinal bars, a pair of w ich are rearwardly extended bertion of t e frame, and rectangular apertures constructed with therein, of a bolster comprismg a cross beam through and rearwarrll beyond which t roar extremities of sai frame bars extend, and blocks secured on the sides of the frame bar extremities having rectangular ,rojec- (ions at their sides, engaging in sai a ertures, and having engagements at their orward ends with the cross beam of the bolster.
