MORRIS E, KANALY, OF ARLINGTON, MASSACHUSETTS; FRANCIS M. KANALY EXECU- TOR OF SAID MORRIS E. KANALY, D ECESEB.

DOOR-HANGER.

13e it k'nown that l, Mouais E. KANALY, ol' Arlington, 1n the county ot' Middlesex and State ot' Massachusetts, have invented certain new Yand uselul Improvements in Door-Hangers, ot which the following is al specilication.

This invention relates to a door hanger and a track therefor which comprises a substantially horizontal tread portion, an inner [lange projecting upwardly from the tread portion, and adapted for attachment to the f .side ot a ear or lmilding. and an outer vertieal tlange projecting downwardly from the tread portion, and serving as a guide for the upper edge ot' the door, said upper edge.

projet-.ting above the lower` edge ol the depending flange, so'lhatit is eontined between said llunge and the corresponding part ol`I the side ol' the ear or building opposite lhe llai'ige.

'l`lie invention has l'or its olijeet'to provide a hanger adapted to have all antii`rietional bearing not only on the'lread portion ol the trat-h. bul also on the inner side o'l the depeudiugflange ot' the traek` so that. the triclional resistance t-o the movement ot' the door ma bereduced tothe minimum.

(ll' theI accompanying drawings, Yforming a part of thisl specification.-fFigure 1 represents a side elevation showing a portion of a ear or building, and portions ot` a sliding door and ol a track therefor, togetheil withl a side elevation of a hanger engaged with the door and track, and embodying my invention. Fig. 2 represents a section on line 2-2 of Fig. 1. Fig. 3 represents a section on line 3--3 of Fig. 1. Fig. t represents an elevation of the inner side of the hanger detached from the door. Fig. 5 represents an edge view of the hanger. Fig. 6 represents a section on line 6-6 of Fig. 5.

The same numerals ofreference the same parts in all the figures.

In the drawings 12 represents a portion of oney side of a freight car or other struc.- ture. containing a doorway, and 13 represents a portion of a door adapted to cover indicate said doorway, the door being movable hori zontally to open and close the opening. A fixed horizontal track is attached to the structure above the doorway, and extends Specification of Letters Patent.

4 along the side of the structure beyond one l end of the doorway, so that it is adapted lto support the door when the latter is open, as

i usual. The track comprises a horizontal j tread portion 14, an innervertical flange 15 projecting upwardly from the inner edge otl l the tread portion, and an outer vertical l flange 16 projecting downwardlyor dependl ing from the outer edge of the tread portion. l I'l'.he inner flange 15 is bolted or otherwise sel cured to the side l2 ot the structure, and the `outer tlauge 16 projects below the upper 'edge of the door, and serves to guide the l latter in its movements, the upper edge of 1b' and the eorresj'ionding portion ot: the

side 12.

The door is provided with suitable hanger trames, of which only one is here shown, the two being alike, so that a description of one will sulliee. The hanger trame is composed of a body portion 1T having means, such as bolts 1S. i`or attachment to the door, and an arm l5) l'ormed on the body portion 1T, and projecting inwardly therefrom over the tread portion 14 of the track. Said arm provided with a cavity or socket 20 in wh ich is loosely located an anti-friction ball 21, the upper side ot whieh beurs ou the upper wall olthe cavity 2l), while its lower side projects downwardly from the arm t9 and bears upon the upper side of thctread por tion let.

The body 17 is provided with a lower arm also projecting inwardly therefrom and which is located below the arm 19, and is provided with a cavity or socket 23, in which is loosely mounted an anti-friction ball 24. A recess is formed between the socketed portion of the ylower arm 22 and the corresponding portion of the body 1T, said recess being formed to receive the lower edge portion of the depending flange 1G ol the track. The ball 24 projects laterally iro'n the socket 23 into said recess, so that when the hanger frame is applied to the door and track, the ball 24 bears simultaneousl against one side of the cavity 23 in. the ower arm 22, and aga-inst the inner side of the depending flange 16.4 Provision is thus made for thc movement of the door with the minimum frictional resistance due to its guidance by the flange 16.

The hanger frame is preferably cast in a single piece from malleable metal, a hole- 26 the door projecting between the outer llange being formed in the body 1T opposite the lower arm y22, for the insertion of the ball 24 into its cavity. To prevent the detachwhen the cavity 23 is not obstructed by the able metal as the hanger frame, and adapted to be bent inwardly after the insertion of the ball, to obstruct the orifice 26, and prelvent the outward 'movement ofthe ball through it, :is indicated in Fig. 3.

To prepare the door for the application of the lizu'iger frame, a mortise is cut in the upper portion of the door for the reception of the lower arm 22.

l. In combination, a track having a hori- Zontal tread portion, and a depending fiange at the outer edge thereof, a hanger frame adapted for attachment to a door and provided with a socketed upper arm projecting over the said tread portion, and a socketed lower arm projecting behind the depending ing on the upper side of the tread, While the y other ball bears on the inner side of the depending flange of the track.

2. A hanger comprising a frame adapted.4

for attachment to a door, and provided with inwardly projecting upper and lower arms, the upper arm having means for engaging the tread portion of a door track, While the lower arm has a cavity which is separated from the corresponding portion of the hanger frame by a iange-receiving recess, and a ball located in said cavity, and projecting therefrom into the recess, the portion oi' the hanger iframe opposite the cavity having an orifice for the insertion of the ball,

and means for contracting the orifice to prevent the removal of the ball.

In testin'iony whereof I have aifixed myl CQF. BROWN, Pii'rnn W. Inzmc'rri.
