SLIDING-DOOR HANGER.

Specification of Letters Patent.

Patented Feb. 18, 1913.

Application filed June 7, 1912. Serial No. 702,193.

To u?! wlmi/t it muy ouf-omi.'

Be it known that I, lViLLiAM F. JACoBs, a citizen of the United States, and a rtsidrnt of tlttarfa. in the eountv of Lasalle and State, of Illinois1 have invented certain new and useful improvements in Sliding-Door Hangers; and I do hereby declare that the following` is a full, clear, and exact description thereof. reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in sliding door hangers, and more particularly to improvements in that class of such hangers comprising a frame adapted to support a connecting member which is attached to the door and provided with wheels adapted i to have rolling contact with a supporting track.

The invention consists in the matters hereinafter described and more. particularly pointed out in the appended claims.

In the drawing--Figure 1 is a view in side elevation of the improved door hanger; Fig. 2 is a plan view of the same; Fig. 3 is a view in eross-setitioi'i taken on line l-l of Figi; FigiV is a view in cross-section taken on line 4 4 of Fig. l showing the method of attaching the door to the hanger. Fig. 5 is a detail section taken on line 5 5 of Fig. 2.

Referring to the said drawing, the frame of the door hanger comprises two similarly shaped side plates A, A, which are rigidly connected at their extremities by means of transversely extending axles, cach consisting of a central cylindric bolt or pin F, which passes at its ends through both side plates.y and a sleeve or bushing M, which fits closely upon the pin between said side plates. The ends of said bushing abut against the inner faces of the side plates, and the ends of the pin are provided with integral heads f, f, which bear against the outer faces of the said side plate-. One of said heads is formed by upsetting or riveting the end of the pin. The ends of the bushing form shoulders against which the plates rest or bear and the heads of the pins act to clamp or hold the plates rigidly against the ends of the bushing. On said axles, between the side plates A. A are mounted wheels or rollers E, E. hereinafter more specifically described. The side plates are also connected by means of a central,

transverse bearing member B rigidly attached at its ends to said plates. As shown and prcfrrahly made, -aid bearing member il has the form of a tube, the ends of which extend through oppositely arranged holes provided in the side plates at the longitutlinai and transverse centers of the same. The ends of said tubular bearing member are secured rigidly to the plates by bein expanded, upset or riveted against the sai plates.

The door P is supported from the bearing member B, by means of a U-shaped yoke O, provided with two deprnding arms 0, 0, and with a central connecting part or loop 0 of inverted U-form, adapted to receive or fit overthe said bearing member. In orderthat the said member Ii may be iuadc no longer than necessary to receive the upper part of the yoke O, the central portion of each side plate A is offset inwardly in such manner that thet'rame is considerably narrowerat its central part than at its ends. In order to stitlen and strengthen the side plates A, the same, which are preferably made of sheet metal, are termed to provide annular ribs a.. c aud longitudinal ribs a', a. The yoke O supported by and depending from said bearing` member B, has its upper portion 0 laterally widened by means of outwardly extending {ianges O2, O2, and its inner downwardly facing surface, which rests on the bearing member. is made of convex shape or outwardly flaring from its central line7 so that when the yoke is hanging in its normal or vert-i cal position, it will be 1n contact with the bearing member at its center only. The purpose of the convex bearing surface is to allow the yoke to have rocking contact with the bearing member B, thereby permitting lateral oscillation or swingimi1 movement in the lower end of the yoke. The lower ends of the arms 0, o of the yoke O are provided with eyes or apertures through which is inserted a removable bolt N held in position by means of a head at one end and a cotter pin N at its opposite end. The bolt N is engaged by a strap P ot U-form, the ends of which are rigidly secured to the opposite sides of the door R, as clearly shown in Fig. 4.

The wheels or rollers E. and the bearings therefor. are constructed as follows: The wheel comprises an inner tubular member I-I with outwardly turned flanges i adapted to tit into a circular and inwardly offset portion of the two similar annular, tread members K. Said tread members K are provided at their meeting edges with outwardly extending flanges lc, f, forming an annular projection K on the center ot the pcriphery of the wheel. It isto be understood that a hanger provided with wheels so made will be employed in connection with a track, suoli as has heretofore been commonly used, having two track members separated by a longitudinal opening or slot into which the tianges K, K of the wheels project. Within the wheel and adjacent to the bearing surface of the tread members is located an annular ring L adapted to reinforce and hold in line with each other the two tread members K. The interior diameter of the tubular member H of the wheel is considerably greater than the exterior of the sleeve or bushing M, so as to form an annular space between said tubular member and bushing. Within such annular space is located a plurality of cylindric, antifriction rollers I of a length substantially equal to the width of the wheel and arranged parallel with the axis of said wheel.

An important feature of my invention consists in the transverse bearing member, which is permanently and rigidly secured to the side plates and forms part of the frame, in connection with a door supporting member or yoke having separated arms and a central loop, which has loosely fitting engagement with the said bearing member, so that it may swing or oscillate thereon in a longitudinal and lateral direction. Said yoke, thus made, is adapted to be engaged with the said bearing member by slipping its arm through the spaces between the side plates, at opposite sides ot the said bearing member. The transverse bearing member, so arranged to form part of the frame, atfords, with the pins or axles on which the wheels are mounted, three transverse members extending between and rigidly connecting the side plates, thereby giving to the frame seat strength and stiness.

Another important feature of the invention is the rocking bearing between the said yoke and the bearing member, affording lateral flexibility between the hanger frame and the supporting yoke. thereby allowing the door to adjust itself laterally to any irregularity in its movement and thus preventing binding of the door and possible breakage of the hanger.

The making of the axles or the bearing pins with a separate bushing, as described` not only ailords a cheap and simple way of rigidly connecting the side plates at their ends` but has the advantage also that such bushing may be made of hard steel, when the pin is made Yof soft steel or iron, thereby affording al durable bearing surface for the anti-friction rollers.

The mechanical structure of the parts may be variously modified without departure from the spirit ot my invention, and I do not, therefore, wish to be limited to the specific construction described, except as pointed out in the appended claims.

l claim as my invention:

1. A sliding door hanger comprising two side plates, two wheels mounted between said side plates, bearing axles for the wheels rigidly attached at their ends to said side plates, a transverse bearing member located between the wheels and permanently and rigidly attached at its ends to said side plates, and means for supporting the door embracing a member which is connected with the door and is provided with a loop adapted for detachable engagement with the said transverse bearing member.
