DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 768,669, dated. August 30, 1904.

Application filed December 15, 1902. Serial No. 135,395. (No model.)

T 0 all whom it may concern:

Be it known that I. WILLIAM LOUDEN, a citizen of the United States, residing at Fairfield, in the county of Jefferson and State of Iowa, have invented a new and useful Improvement in Door-Hangers, of which the following is a specification.

The object of my invention is to provide an inexpensive, neat, and effective construction for door-hangers which will thoroughly protect the wheel and prevent obstructions upon the track from wedging under it; also, to provide an inexpensive and effective flexible c011- nection between the upper and lower sections of a hanger-frame, all as hereinafter set forth and as definitely embodied in the claims.

Referring to the drawings forming a part of this specification, Figure 1 is a rear elevation of a door-hanger embodying my invention. Fig. 2 is a vertical section on the line 2 2 of Fig. 1. Fig. 8 is a diagram showing how the strap forming the upper section of the hanger-frame is cut from a strip of metal. Fig. 4 is a perspective of the connecting-loop.

In the drawings, A represents a track-rail, and B a bracket by means of which it may be attached to a wall.

C is the casing or frame in which the trackwheel IV is mounted, and it preferably has its lower end turned up under the track, so as to form a hook H to provide for a flexible con nection with a lower section, to which the door is to be attached, and a guide-lug to prevent the hanger from getting off the track, all in the usual manner.

D represents a connecting-loop between the casingC and a strap S, which is adapted to be secured to a door by means of bolts I, also in the usual manner. The loopDis made essentially triangular in vertical section and is provided with an upper central member E and two lower side members G, with an opening between them. The member E is made essentially semicircular in cross-section, the rounded side being below and the flat side above. The rounded side is adapted to rest and turn to some extent in the hook H, formed by the bending of the lower part of the casingC, and the strap Sis hung upon the bars G. The flat side of the memberE is preferably made somewhat concave in cross-section, so as to correspond approximately (when hung in the hook H)with a circle drawn from a center in line with the point of contact of the wheel W upon the upper edge of the rail A. The members G are made with the upper sides horizontally flattened and preferably have downwardly extending flanges J formed on the lower sides of their outer edges.

Some of the objects and advantages of the above-described construction of the loop D are as follows: The member E is made to occupy a comparatively large amount of space laterally and a comparatively small amount of space vertically. In this way the largest practical amount of space is secured between the point of the hook H and its back, (where the member E is fitted.) and this affords the largest practical amount of room for lateral variations of the lower end of the casing C in relation to the track A, also the smallest amount of space vertically is required between the lower portion of the hook H and the lower edge of the track A. Hence while the space for the vertical movement of the door is increased the amount of vertical space usually required for the loop D below the track is decreased, and a closer fit between the door and the track is secured. The upper side of the member E being slightly conoaved, as described, it will always remain in a practically definite relation to the lower edge of the track-rail A without regard to its lateral variations. In addition to this the opening between the members Gr makes the loop lighter than if it were made solid in the usual way. and it places the support of the strap S entirely at the corner, where it should be, instead of entirely or mostly in the center of the horizontally-disposed upper end of the strap,where the weight of the door might be liable to bend it, also the small amount of metal required to form the flanges J adds more strength to the members G than many times the metal filled in between them and at the same time affords a better support for the corners of the strap S.

The upper portion of the casing O is made substantially the same width as the diameter of the wheel W, so as to efl ectually shield it, and on the inner side of the casing projecting Eli points P are left on the corners of the strip of metal which forms it. These points P, in conconjunction with the edges of the body of the casing on the opposite side of the wheel, form guides to keep the casing straight on the track and tend to push birds nests and other obstructions which may be on the track ahead of them and to prevent said obstructions from getting wedged fast under the wheel. Practically no more metal is required to form the casing with the points P than to leave them off, as has been heretofore done, because the edges of the strip of metal which forms the lower end of the casing having the hook H are cut away to make it narrower than the body, as shown by H in Fig. 4c, and in cutting the casing-blank out of a strip or band of metal the cut-away parts on one end are sufiicient to form the points P on the other. Therefore little or no additional expense is incurred, and the advantages of these points in door-hanger casings of this class is clearly apparent.

The axle for the wheel WV passes through the hole L in the body of the casing U and also through the hole L in the recessed portion between the prongs P.

In casings made to completelv'shield the wheel WV, as in this invention, it is generally difficult to oil the bearings of the wheel. To overcome this defect, 1 have placed an oil-hole K in the metal strip which forms the casing, so as to be immediately over the hole through which the wheel-bearing is passed and so as i to come in close proximity to the bearing of the wheel. By this means the bearings may be easily oiled without having to reach in from one edge of the casing. These holes are preferably placed on the side of the casing away from the bracket A, but can be placed on either or both sides, if desired.

hat 1 claim is- 1. in a door-hanger, the combination with an upper section cmnprising vin its construction a casing formed with a loop at its upper end and a hook at its lower end, a track-wheel journaled in said loop, of a lower section comprising a strap constructed to embrace and support a door, and a connecting-loop essentially triangular in cross-section and having three separatehorizontally-disposed members joining the corners thereof, one of said members being adapted to connect with the hook of the upper section, and the other two members being adapted to connect with the lower section.

2. In a door-hanger, the combination with an upper section comprising in its construction a casing formed with a loop at its upper end and a hook atits lower end, atrack-wheel 1 journaled in said loop, of a lower section comprising a strap constructed to embrace and support a door, and a connecting-loop essentially triangular in cross-section and having three separate horizontally-disposed members joining the corners thereof, one of said members being substantially semicircular in crosssection and adapted to hang in the hook of the upper section, and the other two members being adapted to connect with the lower section.

In a door-hanger, the combination with an upper section comprising in its construction a casing formed with a loop at its lower end, a track-wheel journaled in said loop, of a lower section comprising a strap'constructed to embrace and support a door, and aconnecting-loop essentially triangular in crosssection and having three separate horizontally-disposed members joining the corners thereof, one of said members being adapted to connect with the hook of the upper section, and the other two members having their upper faces flattened, and provided on their outer edges with downwardly projecting flanges, and being adapted to connect with the lower section.

4. In a door-hanger, a casing comprising a sheet-metal strap cut and bent so that oneof its ends will incase and substantially cover a track-wheel, and its other end will form a hook for a door-supporting device, said firstmentioned end being recessed to leave on the opposite edges of the strap projecting prongs P P extending down substantially to a line drawn horizontally through the lower edge of the wheel, and a hole for the wheel-axle situated at a distance from the bottom of said recess, the hooked end of the strap being narrowed so that it may be cut out of material between the prongs P P of an adjoining strap,

whereby material will be saved and a narrower loop and door-supporting device therefor will be required for the narrowed hook end of the casing.

5. In door-hangers, a casing containing a wheel adapted to run upon a track, said casing being adapted to shield and cover up said wheel, and having holes in its sides to admit the bearings therefor, and an extra hole in one or both sides of the casing adjacent to the holes for said bearings, substantially as described.
