Toi'all who/nt it may concern:

Be it known that I, MORRIS E. KANALY, of

i Arlington, in the county of Middlesex and cation.

State of Massachusetts, haveinvented certain new and useful` Improvements in Door- Hangers, of which the following is a specifi- This invention relates to hangers for sliding doors, in which the hangers project above the upper edge ofthe door, and engagea f grooved or channeled track affbced to the vOnline 2-2'of Fig. 1.

side 1of the struc ture having the opening guarded byrthe door.

The invention hasfor its object to provide a door hangery of `simple and durable construction, adapted to permit the movement of the door with the minimum frictional resistance, the hanger being provided with an anti-friction ball in rolling engagement with boththe hanger and the, track, the construction being such that the engagement of a pairof hangers with the track will prevent the door to which the hangers are attached, from being displaced to derail the hangers.

Of the accompanying drawings, forming a part of this specification, Figure 1y represents a side elevation of'a hanger embodying my invention, with fragmentary portions of the track and door. Fig. 2 represents a section Fig. 3 represents a section on line 3 3 of Fig. 2. Fig. 4 represents a section Online 4 4 of Fig. 2, the track shown in Fig. 2 being omitted.

'The same letters of refercnce'indicatc the same parts |mall the figures.

y improved hanger includes a shank portion .12, the lower portion of which is adapted to be secured by bolts 13, lor other suitable fastenings, to a door 14., the upper end of the shank projecting laterally above the door, as p at 15 and formed with a downwardly projecting portion whichV is separated from the shank by a recess 17 and is provided with a cavity or socket 18 open at its under side whereby it is adapted to form an anti-friction ball seat. The portion of the hanger which connects .the shanklwith the socketed portion above the recess 17'is indicatedat 16. A ball 19 is seated i'n'lthe cavity or socket 18 and projects bolowthe mouth thereof to .bear on as rack 20y The socketed .portion is, for convenience, hereinafter referredto as'the head. lt is provided with means for engaging the ball so that it cannot leave the cavity 18, although free to rotate loosely therein,

the preferred means being an inwardlyprof-- j ectin g bead 21.on.the inner wall of the cavity, said bead forming' a mouth, which is slight y narrower than the diameter of the ball, and is located below the center of the ball, as shown in Fig. 2. with slots 22 extending through the bead 2 1,

= and making the contracted mouth of the cavity sufficiently resilient to enable the ball .to be forced into the cavity, the mouth spring ing Outward to permit the inward movement of the ball, and then contracting after' the center of the ball has passed .the bead 21. v

The socket is preferably slight] elongated in the direction of movement o the door, as shown in Fig. 3, so that the head has alimited freedom of movement independent of the ball. i 1

The track which c'operates with -the hanger, is composed of the central portion 20 on which the ball 19 runs, the back portion 23, which is bolted or otherwise secured to the side of the car or, other structure, having the door. opening which is guarded by the door 14, and an outer portion or flange' 24 which projects upwardly from the central portion 20 into the recess 17, said flangev forming a stop adapted to prevent outward lateral Vdisplacement of the hanger by arresting the outward movement ofthe head 15, and also serving to guide the parts during the travel of thc'- hanger andto prevent possibility of the ball engaging the flange 24 or riding up on said flange. T e arts are so proportloned that the head and all cannot be lifted above the 'flange 24,`4 while the hanger is attached to the door, the upper clear the flange 24. f

it is obvious that two of the above-.described hangers will be usedfor each door7 the track being extended to cooperate with both hangers, and providing `for 'the' travel required forthe opening and closing of the door.

I claim:

1. In a door hanger, the combination with a shank adapted for attachment to a door and having a socketedhead offset from its upper from t e shank by a ,recess adated to receive a flange of a track, of .a )all loosely engaged with the socket of thehead, and projecting below the latter, the socket having 'means' for retaining the ball.

a', door hanger the combination with rtion, the said head'being separated 60 'i The head is preferably provided a shank edaptecl for attachment' to st door and having a socketed head offset from its upper portion, the said head being separated from the shank by a recess adapted to receive a flange of a track, of a ball loosely engaged with the socket of the head, "and projecting below the latten'the socket having a contracted mouth the width of which is slightly less than the diameter of the ball, seid mouth being slotted to make it exi pansible. j

3. In a door hanger the combination of a track having a central hanger-supporting portion, -and an upwardly projecting fla-nge, and a door supportin hanger comprising a 15 shank, a socketd Iec offset from the shank, and a ball seatecl'in the socket of the head and projecting below the latter, the head st nd shank being separated by a recess which receives the track llange. 20

In testimony whereof' Ihave ahxed my signature, in presence of two witnesses.
