This invention relates to improvements in car construction,

One object of the invention is to provide a combined locking and center pin arrangement for railway cars of rugged design, in-

cluding a connecting element comprising a plural-ity of sections and a spacing member, certain of the sections having shouldered engagement with the car holsters to prevent separation thereof, the sections when collapsed by removing the spacing member being of such dimensions in cross section that they will pass freely through the center pin receiving openings, the shouldered engage- 1'5 ment between the sections and the cooperating bolster being provided by a tapered seat on the bolster and cooperating expanded tapered head portions on said sections.

Another object of the invention is to provide means for connecting the body and truck holsters of railway cars including a sectional center'l'pin comprising outer sections and a spreading member, said outer sections being interlocked with the cooperating bolster by a tapered head of greater size than the main sha-nk portion of the pin and cooperating with a vtapered Vseat on the bolster, portions of'said 'head Vbeing Aformed on each of the outer 'sections and the sections being held apart by the spreading "member to lool; the head to the-bolster, 'Said outer ysections being collapsible "when the spreading 'member' is withdrawn from betweenvthe same to reduce the cross sectional a'rea'oi" said tapered head to permit insertion of the parts through the pin receiving openings of the holsters.

further 'object of the invention is toV provide acenter pin constructionffor connecting the body and truck holsters ora railway car provided 'with aligned center pin receiving openings, wherein the pinis headed at oppositeende to interlock the'eanie' with both bol,- stere'end is collapsible to reduce the sizeof each of the heads "to permit insertion of the parte through the piny receiving openings, by ent-"eringthe'same either through the body or truck bolster opening, one of saidheadjinembers 'being tapered and cooperating with a tapered seat 'on the jeorree'ponding bolster. do' A niore 'specific cbjectof `the invention is to provide a combined locking andcenter pin l arrangement for body and truck holsters of railway cars, including a pin proper composed o'f a pair of counterpart outer sections and a spreading member interposed therebei tween, each of the outer sections having enlargements at the opposite ends thereofforming portions of head members by which the sections are anchored to both holsters, one of said heads being tapered, increasing in size toward the extremity of the pin, and the cooperating bolster being formed with a ltapered seat for said head, whereby, when the spreading member is withdrawn from between said sections, the latterare collapsible to effect reduction in size of the pin, the tapered head member being of such cross sectional area that the sections pass through the pin receiving opening 'of the holster when the parts are collapsed.

Other and further objects of the invention will more clearly appear from the description and claims hereinafter following.

Inwthe drawing forming a part of this specification, Figure 1 is a top plan view of 75 the body and truck holsters of a railwayr car, illustrating my improvements in connection therewith. Figure 2 is a vertical sectional view, corresponding substantially to the line 2-2 of Figure 1. Figure 3 is a so horizontal transverse sectional view, partly broken away, corresponding substantially to the line 3 3 of Figure 2. And Figure 4 isA a detailedelevational view of a spreading or Vfiller member employed in connection with y85 my improved combined locking and center pin construction.

In said drawing, 10 indicates generally a portion of the body bolster of a railway car and 11 the cooperating truck bolster. The 90 body bolster is provided with the usual top and bottom webs and a cylindrical sleeve sectionf12 connecting the same. At the bottom, the bolster 10 isprovided with a downward projection 13 having a substantially spherical 95 bearing surface cooperating with a spherical bearing seat 14 formed on a ybearing block 15 seated in a pocket 16 on the'truck bolster.

The truckbolster 11 is also provided with 100 the usual top and bottom webs connected by a central sleeve-like section 17. The body and truck holsters are provided with center pin receiving openings and an aligned opening in the Ybearing plate 15, the opening in the bearing` plate being surrounded by an upstanding' annular flange 18 which engages within a. seat 19 formed on the bottom of the body bolster.

In carrying out my invention, I provide the truck bolster with a center pin receiving opening 20 which is of smaller diameter than the lnain portion of the sleeve-like section 17, whereby a pocket 21 is provided to accommodate the head member at the lower end of the center pin. An annular shoulder 22 is thus provided in the pocket surrounding the center pin receiving opening 20. The bearing plate 15 is provided with a center pin receiving opening 23 of the same diameter as cned, as clearly shown in Figure 2, and said lower end portion of the sleeve is provided V^V`-with a center pin opening 24 of substantially the same diameter as the openings 2O and 23. Immediately above the opening 24, the inner faces of the walls of the sleeve 12 are flared upwardly to provide a tapered seat 25 which fifcooperates with thecenter .pin membeiyas hereinafter more clearly pointed out. Above the tapered seat 25, the opening in the bolster may be made of. larger diameter than the AAupper portion of the seat, or said opening may be made of thesame diameter as the upper portion of the seat.

My improved combinedv center and locking pin proper comprises a pair of counterpart` outer sections A-A and a'central section B w'which forms a filler or spreading member.

Each of the sections A has a central shank portion 26 and a laterally outwardly projecting flange 27 at the bottom end thereof. At the upper end, each section is enlarged` as indicated at 28. The enlargement 28 of each section fits the corresponding side of the Y.

tapered seat 25 of the bolster 10, as clearly illustrated in Figures 1 and 2.

VOn theA inner sides, the sections A present flat vertical faces. which, when brought into abutment b v displacing one section laterally inwardly, reduce the crosssectionalarea of the head formedby thek flange portions 27 at the bottom ends of the sections A and the cross sectional area of the retaining means formed by the enlargements 28 atY the upper end of said sections, so that the displaced sec-.

tion Amay be withdrawn, the .head portion at the bottomend of said section and the retaining `means at the` top end thereof being ofsuch a size as to pass freely through the pin receiving openings 20, 23 and24. The remaining section may then be displaced laterallyto register the flange and enlargement thereof with the pin receiving openings, and is then withdrawn in a similar manner. As will be clear upon reference to Figures 1 and 3, the opposite side portions of the head formed by the flanges 27, as well as the opposite side portions of the retaining means formed by the enlargement28, arefcut away so as to'provide proper clearance to permit the flanges and enlargements of the sections A to pass through the' pin receiving openings of the holsters.-

The filler or spreading member B is in the form of a'relatively thick plate having upwardly diverging side edge portions 29 adjacent the upperY end thereof, which are adapted to seat on the opposite side walls of the tapered seat 25 to limit downward move ment of said member B. The member B is of such a thickness that it will hold thev sections A separated to such an extent that the flanges v27 will overhang the annular shoulder 22 and that the tapered enlargements 28 will be seated on the walls of the tapered seat In order to facilitate the removal of the member B, the same is preferably provided with an upstanding lug-like member 30 at the upper end thereof, provided with an opening 31 adapted to cooperate with the hook portion of a tool by which the member B may be lifted upwardly.

The outer sections A are also preferably provided with similar lugs 32-32 vhaving openings 33-38 within which a tool may be engaged to lift the same out of the opening in the. bolster 10.

In assembling my improved combined locking and center pin with the body and truck bolsters of a railway car, one of the. sections A is first .inserted through the center pin openings of the bolsters and displaced laterally to overlap the flange 27 with the shoulder of the truck bolster and seat the head section 28 on the tapered seat portion 25. The other section A is then inserted, the inner side thereof being at this time in contact with the inner side ofthe section A first applied, so as to reducethe cross sectional area of the head member and the taperedv retaining means, as hereinbefore pointed out, so that the flange and enlargement of the last named section will pass through the pin receiving openings of the holsters; VAs will be-evident,the sections A-may be applied by inserti-ng the same in succession through `the top of the body bolster and passing the flanges at-the lower ends thereof through said pin receiving openings until the same are dislil 0 posed below the annular shoulder 22 of the y truck bolster, or by inserting the sections successively upwardly through theV opening of the truck bolsterl and passingV the enlargements l28 through the pin recelvingopenings until said enlargements register with the seat 25. the'prts have-been thus far lthrough the opening in the body bolster.V

The-sections will thus be held apart with the flanges 27 in overlapping relation with the annular shoulder 22 and Ythe enlargements 28 seated on the opposite side wall portions :of the seat 25, thereby anchoring the pin to both bolsters and preventing separation of the latter.

When it is desired to separate the bolsters, the pin is readily removed by withdrawing themember B from between the sections A and then collapsing the sections by displacingr one of the same laterally inwardly and bringing them into contact, whereupon the displaced section may be irst withdrawn, the

i other section being then displaced laterally inwardly to register the enlargement and Harige thereof with the pin receiving openings, whereupon said last named section may be withdrawn. As will be evident, the sections may be withdrawn either through the bers on both bolsters. It is also pointed out that the member B may be inserted through the opening in the truck bolster, instead of through the opening in the body bolster. as shown, it being merely necessary to form the member of the same width from top to bottom, eliminating the inclined edge portions 29 and providing any well known retaining means for limiting the downward movement of said member.

While I have herein shown and described what I now consider the preferred manner 0I carrying out my invention, the same is merely illustrative and I contemplate all changes and modifications which come within the scope of the claims appended hereto.

I claim: l. In car construction, the combination with body and truck bolsters having aligned y center pin receiving openings; of a pin hav- "in a reverse direction, said pin comprising a plurality ot' -sections including a spreading member which when removed permits collapse 'o the pin to eiiect reduction in size oi' said tapered head to allow passage thereof through the pin receiving openings.
