DOOR-HANGER.

SlPECIFIGATION forming part of Letters Patent No. 529,919, dated November 27, 1894.

Application filed January 16, 1894- Serial No. 497,065- (No model.)

To all whom it may concern:

Be it known that I, ALBA T. KINGSLEY, of Millport, in the county of Ohemung and State of New York, have invented new and useful Improvements in Door-Hangers; and I do hereby declare the following to be a full,.

clear, and exact description of said invention,

7 reference being had to the accompanying drawings, and to the letters of reference [0 marked thereon, which form a part of this specification.

My invention relates to door hangers and has particular reference to that type of hangers in which the trunnions of the wheel roll on extended bearings, the principle involved being shown in United States Patents No. 43,205, dated June 21, 1864, and No. 253,471, dated February 7, 1882.

The object of my invention is to produce a door hanger of this type which shall be simple, durable, cheap and possessing all necessary strength and rigidity.

My invention consists in the construction and combination of parts as hereinafter described and claimed.

In the drawings, Figure 1 is a rear perspective View of the hanger, omitting the wheel. Fig. 2 is an enlarged detail perspective of a portion of the hanger showingone of the bent lips at one end of the traveling rail. Fig. 3 is a vertical section of the hanger and its wheel or roller. Fig. 4 is a side elevation of my improved wheel, shown larger than in Fig. 3. Fig. 5 is a section on line 5-5 of Fig. 4. Fig. 6 is a section on line 6-6 of Fig. 4, looking upward.

Similar reference letters indicate corresponding parts in the several views.

A represents the hanger composed of the attaching plate 0. having traveling rails, all formed integrally of metal, the said plate having an opening (1 preferably rectangular in form. Above the opening is a horizontal slot a and above said slot the metal is continuous and arched over, and provided with another slot (1 near its bent over edge. The upper sides of the slots a and'a form companion traveling rails which ride on the trunnions b of the roller B. (See Fig. 3.)

The hanger as so far described may be of cast or wrought iron, or sheet metal, such as mild steel. I prefer sheet metal because of the comparative cheapness 0f the article so made and its greater strength; but I do not regard the choice of metals as constituting invention.

A door hanger traveling rail or rider bar made of sheet metal, if it is to be durable, requires some provision to prevent the undue wear of, or cutting into, the trunnions of the roller, and to prevent the said trunnions from wearing a notch at the ends of the said rails. A sheet metal rider bar having its bearing portions for the roller trunnions composed of straight edges of the metal, has been made, but is objectionable, in that, after some use, the said edges by always traveling in contact with the same portion of the trunnions will wear a groove in the latter. Furthermore, since it is of frequent occurrence that the trunnions reach the ends of the rider bar before the roller and the door have ceased traveling, there is an excessive frictional rotation of the trunnions at the end of the rider bar which, when straight edge bearings are employed, results in wearing notches at the ends of the rider bar which will finally prevent the proper return travel of the roller trunnions along such edges. I overcome these objections by making the edges of the metal angular at the ends of the bearing surfaces and then bending such angular portions to a horizontal plane, so that the sides instead of the 'edges of the sheet metal will ride on the trunnions.

One of the traveling rails a is formed by the upper edge of the slot u while the companion traveling rail a is formed by the upper edge of the slot a the plate being arched over as above described, bringing the two slots parallel with each other, the ends of the slots forming stops a for the roller trunnions. At each end of each traveling rail, the metal is cut out, so as to leave an angular projection, as indicated by the dotted lines in Fig. 2, and 5 each such projection is then bentto one side and then given a return bend underneath, as shown in full lines, so as to form a flat bearing a." for the trunnion on theside of the metal. To prevent the further bending up of the I00 bearings a by the weight of the door borne on the trunnions, the ends of the slots a a, are slightly notched, as at a and the edge of the horizontal bearing a is sprung into such notch, as shown in Fig. 2, thereby locking the two partstogether.

To strengthen the side portions of the attaching plate, when made of sheet metal the metal is bent to form ribs a and these ribs extend up past the slot a so as to strengthen the portion of the hanger which extends above the top of the door, and thus prevent lateral bending at all points. It is to be understood that the side of the attaching plate which is visible in Fig. 1,is the side which is next the door, and that the ribs project on the face of the hanger. These ribs prevent liability of bending of the metal at the points of location of the holes for the attaching screws or bolts.

The wheel or roller B is preferably composed of two disks 1), b, of metal, such as mild steel, each of which is struck up to form a central boss 19*, perforated as shown, for the axle 19 having the trunnions b, b, the disks being also bent outward at their periphery, as at b, to form the tread which maybe somewhat V-shaped, as shown, or have any other suitable shape. Each disk is provided with a circular series of lips 6 each lip formed by making a radial slit in the metal, with two short slits at its ends and at a right angle thereto, and then bending the metal between the three slits at an angle from the disk. The axle b is formed at each end with two shoulders 1), b the distance from one shoulder to the other being slightly greater than the thickness of the metal of the disks.

The wheel is a rivetless one, and its parts are assembled and secured as follows: One disk is fitted against one shoulder 19 and the other disk against the other shoulder b, with the lips of each disk passing through the openings formed by the bending out of the lips of the other disk, the two lips of a pair thus passing each other. The ends of the lips are then clinched down in opposite directions, as clearly shown in Fig. 6, and the two shoulders b of the axle are pressed down so as to expand over and upon the disks around their central openings, as shown in Fig. 5. Thus the parts of' the wheel are securely held and made rigid, without the use of rivets; that is, such fastening devices commonly known as rivets. It is to be understood, however, that the axle b forms a device the equivalent ot a rivet for securely holding the central portions of the disks at a fixed distance apart, owing to the said disks being held against the shoulders I) by the heading over of the shoulders I)". disks to the axle so that there can be no rotation of the former on the latter.

Having now described my invention, what I claim is-- 1. A door hanger traveling rail composed of sheet metal having portions at the ends of the bearing surfaces bent outward and under to form broad horizontal bearings on the side. of the sheet metal and means for preventing the horizontal portions from being bent out of normal position, substantially as described. 2. A door hanger traveling rail composed of sheet metal and having stops provided with notches at the ends of its bearing surfaces, portions of the ends of the latter being bent outward and then horizontally and fitted to said notches, substantially as described.

In testimony whereof I afiix my signature in presence of two subscribing witnesses.
