DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 695,057, dated March 11, 1902 Application filed March 3, 1900. Serial No- '7,2l2. (No model.)

To wZZ whom it may concern.-

Be it known that I, MORRIS E. KANALY, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Door-Hangers, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to door-hangers, is designed especially for use on sliding doors, and particularly on freight-car doors, is an improvement upon the invention shown and described in the Letters Patent No. 435,499, granted to me as the assignee of Elmer N. Hutchins, September 2, 1890; and it consists in certain novel features of construction, ar

rangement', and combination of part-S, which.

will be readily understood by reference to the description of the accompanying drawings and to the claim hereto appended and in which my invention is clearly pointed out.

Figure 1 of the drawings isapartial elevation of a sliding car-door, illustrating my invention, with the door open. Fig. 2 is an elevation of a smaller portion of said door with a single hanger attached and a portion of the track with the door in closed position and drawn to an enlarged scale. Fig. 3 is a plan of the same. Fig. 4 is a vertical section on line was on Fig. 2 with the truck removed. Fig. 5 is an inside elevation of one of the hanger-brackets. Fig. 6 is a section of same on line y Q] on Fig. 5. Fig. 7 is a partial inside elevation of one of said brackets and illustrating a slight modification thereof, and Fig. 8 is a section on line .2 .2 on Fig. 7.

In the drawings, 1 represents a portion of the side wall of a car or building, 2 represents a portion of a doorway cut through the same, and 3 is a sliding door designed to cover said doorway.

A grooved steel track-rail 4: is secured to the wall 1 by means of the brackets 5, held by suitable screws or bolts just above the upper edge of the door 3, as shown in Figs. 1, 2, 3, and 4.

The door 3 has secured to its outer face two pairs of brackets 6 6, each pair of which are connected together by the rider bar 7, as shown. Each bracket 6 is provided with a vertical and a horizontal arm, to be secured by screws or bolts 8 S to the vertical face of said door, and with a shoulder 9 to rest upon the upper edge of the door, as shown in Fig. 4. Said bracket is also provided with an up wardly-projecting arm which is offset, so as to overhang the center of the upper edge of the door, in the upper end of which arm is formed a rectangular mortise or opening 10 to receive one end of the rider-bar 7, which is firmly secured therein by an accurate fit in said mortise, and the pin 11, which passes transversely through said bracket and said bar, as shown in Fig. 2.

Two trucks 12,each composed of two flanged disks mounted in fixed positions on a short steel axle 13, with their inner faces at a sufficient distance apart to permit said riderbar 7 to rest upon said axles, while the an nular surfaces 14 of said trucks rest upon the upper edges of the ribs of the track-rail 4, along which said trucks roll as the door is opened or closed.

The inner edges of the upper arms of the brackets 6 are made of such a thickness that the flanges of the trucks 12 will span or inclose said portions of the brackets and. the annular surfaces 14: will abut against said bracket, and thus check the rotation of said trucks at each extreme of the movement of said door.

Each bracket 6 is provided with a downwardly-projecting tapered lug 15, which may have a semicircular lower end and be as wide as the upper arm of said bracket, as shown at 15 in Figs. 4 and 5, or it may be of much less width than said arm and rectangular in form as viewed from the front or rear, as shown in Fig. 7 at 16. lVhen saidlug is made of the form shown in Figs. 7and 8,. the bracket 6 has formed therein opposite said lug the rectangular opening 17 of a somewhatgreater area than the front side of said lug, so that said lug may be cast without the trouble ofmaking and setting a core.

In the practical operation of the hanger shown and described in the before-cited Let ters Patent it has been found that, owing to the peculiar shape of the rider-bar when made integral with the arms by which it is attached to the door and having the downwardly-projecting portions which serve as stops to limit the travel of said rider-bar, by coming in contact with the axle of the truck a very injurious wearing action takes place between said rider-bar and axle, which in a comparatively short time renders said parts unserviceable and necessitates the replacing of said parts with new ones. The object of my invention is to obviate this objection or reduce it to a minimum, which is accomplished by making the rider-bar separate from the hanger-arms, with straight parallel edges throughout and rectangular in crosssection and mounted in sockets in the upper ends of two separate brackets or hanger-arms secured to the vertical face of the door, each provided with a shoulder to rest upon the up per edge of the door and having the inner portions of their upper ends constructed and arranged to enter between the flanges of the trucks and abut against the peripheries of each of said trucks, one upon each side of said rider-bar, where the leverage is very much greater than at periphery of the axle, and as a consequence the movement of said riderbar is arrested with much less shock or injury to the parts.

By making the rider-bar separate from the brackets or hanger-arms which support it and with straight parallel edges throughout itsentire length and removably mounted in sockets in said brackets and securing it therein by means of transverse fastenings arranged centrally between the upper and lower edges of said rider-bar said bar when badly worn.

upon its under edge may be readily turned upside down to bring a new surface into contact with the surface of the axle, and when both edges are so badly worn as to render the bar unserviceable it can be easily removed and a new one put in its place.

Another objection to the construction of the rider-bar and hanger-arms in one piece, as shown and described in said prior patent, is the uncertainty of the device being secured to the door, so that the rider-bar will be accurately parallel to the upper edge of the door, because of therebeing no stop or shoulder on said hanger-arms to determine their positions upon the door. This is a very important matter, as unless both rider-bars are perfectly parallel to the top edge of the door and equidistant therefrom the operation of the door will be unsatisfactory and excessive wear or cutting of the rider-bars and truck-axles will take place.

By making the brackets or hanger-arms 6 separate from the rider-bar and providing each bracket with-the shoulder 9 at a given distancefrom the socket in which the riderbar 7 is set said brackets or hanger-arms may be readily and easily secured to the door, so that both rider-bars will be parallel to the upper edge of the door and'equidistant therefrom.

The downwardly-projecting lug 15 or 16 enters the groove in the upper side of the track-rail 4, as shown in Fig. 4, so as to prevent the possibility of the trucks leaving the track.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

In a door-hanger, the combination with a sliding door, of a track-rail comprising two upwardly-projecting parallel ribs, formed integral with each other; a single pair of supporting-trucks mounted upon a common axis and constructed and arranged to rest, and roll, one upon each of said ribs, and be guided thereby; a rider-bar constructed and arranged to rest upon, and be moved endwise over, said truck-axle; and supports for said rider-bar, one at each end, secured to said door in fixed positions, with the inner faces of the upper portions of said supports placed at such a distance apart, and so constructed as to alternately contact with the peripheries of said trucks, on opposite sides of their common axis, to limit the travel of said rider-bar, and consequently of the door, in either direction.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 26th day of February, A. D. 1900.

MORRIS E. KANALY.
