` (loflllodaL) A TTORNE m2 UNITED ARTHUR S. HOOK, OF OTTAWA, ILLINOIS.
SPECIFICATION `forming part of Letters Patent No. 680,996, dated August 20, 1901.
Application tiled January 26, 1901. Serial No. 44,822. (No model.)
To @ZZ whom t may concern:
Be it known that I, ARTHUR S. HOOK, a citilzen of the UnitedStates, residing in Ottawa,`
in the county of Lasalle and State of Illinois, have inventedanew and usefullmprovement in Door-Hangers, of` which the following is a specification.
This invention relates to the construction of the hangers used upon sliding doors, and has beendevised more especially1 for use upon the doors of barns and such buildings.
The invention is designed to afford a cheaper andbetter construction than has been used heretofore; and it consists in the novel features hereinafter specified, and pointed out in the claims.
Figurelis a partial elevation of a door provided with my improved hanger. Fig. 2 is a transverse vertical section. Fig. 3 is an enlarged section of a portionof the hanger.
In said drawings, 4L represents the side of the barn or other building, and 5 represents the door.
6 is a projecting bracket attached to the barn and having an arm 7, upon which the hanger-track 8 is supported. The track consists of a fiat bar of metal arranged edgewise and supported upon a series of the brackets described. The hanger-frame is shown at 9,
and consists of an integral piece of flat metal with its upper end bent over to inclose and;
form bearings upon both sides for the supporting-roller 10 and with its lower end bent `up to inclose and form bearings upon .both
sides for a guide-roller 11.
the guider-roller revolves upon a bolt 13.
This latter bolt passes through verticallyelongated openings 14 14 in the hanger, so that it can be adjusted at diderent positions .to accommodate tracks of different height `or dimensions. The guide-roller may, however, be whollyomitted if the bent end of the hanger is extended above the lower edge of the track in a manner which is familiar to manufacturers of-.these hangers.
The supporting-roller is` provided with a ball-bearing consisting of a single series of l The supporting-v p roller is secured in place by the bolt 12, and` balls 15, for which a race 16 is provided in the body of the roller by grooving the central portion of the opening through the roller, as seen at Fig. 3. The balls are confined in this `groove by two cones 17, one at either side of the balls, and both preferably made removable from the roller. The cones are held in position in the roller by the contact of their outer ends with the body and bent-over end of the hanger. As heretofore made by me, these cones haveI been loosely inserted in the roller, and the bo'lt 12 passes through and supports them and through them supports the balls and the roller. The bolt 12 has no threaded engagement with the cones, and, in fact, they are not fitted tight thereon. This construction of a ball-bearing is very economical in manufacture and renders the rotation of the supporting-roller very easy and `comparatively frictionless.
The door is attached to the hanger by means of a strap 18, passing over a pivot bolt or pintle 19, lying in the lower loop of the hanger, the hanger being cut away, as shown at 20, togive room to the strap. I thus utilize the lower end of the hanger as a portion of the hinge by which the door is secured to the hanger, the strap forming one member of the hinge and the hanger the other and the pintleor bolt passing through both.
I claiml. The combination in a door-hanger of frame 9, roller l0, a single series of balls movingin a race formed centrally in the roller, independent, disconnected cones at opposite sides of the balls, and an axial bolt upon which the cones are slidingly fitted and confined by the frame, substantially as specified.
2. The door-hanger the frame whereof is `bent upward at the lower end, and such bent lower end is made to support both a guiding device engaging the track, and a pivot of the hinge by which the door is supported from the hanger, substantially as specified.
