6 Claims. (CI. 16-97) This invention relates to improvements in door hangers for use with doors of the sliding type.

An object of this invention is to provide an improved and simplified form of door hanger for sliding doors.

Another object of this invention is to provide a door hanger construction especially adapted to ease in assembly, of the type for use with an overhead track in the form of a bar wherein a pair of vertically spaced rollers engage the bar on the upper and lower faces, with the lower rollers adapted for adjusting the play or clearance in a vertical direction between the bar and the cooperating rollers.

Another object of this invention is to provide in a double roller hanger of this type a construction wherein the bearing pin for each roller, one of which is an eccentric pin, is supported at both ends by a construction which facilitates assembly of the structure and especially simplicity in mounting the eccentric pin.

Another object of this invention is to provide a dloor hanger which will not bind on the hanger rai Other and more detailed objects of the invention will be apparent from the following description of the embodiment thereof illustrated in the attached drawings.

This invention resides substantially in the combination, construction, arrangement and relative location of parts, all as will be described in detail below.

In the accompanying drawings,

Figure l is a front elevational view of the hanger of this invention;

Figure 2 is a cross-sectional view taken on the lines 2-2 of Figure 1; and

Figure 3 is a side elevational view of the eccentric bearing pin for the lower roller.

The structure as illustrated in the drawings is shown by way of example as comprising a plate Ii) of suitable material and thickness, as for example a plate of iron about of an inch thick in one practical form. The upper end of the plate which has converging sides and a truncated end is reversely bent upon itself to form the depending flange H spaced from the main body of the plate It. J ournaled in the back portion of the depending flange is a wheel or roller l2 which is rotatably mounted upon a bolt 13- which passes through the rear plate and is threadedly engaged at its end in the depending flange H. Similarly the lower rectangular edge of the plate is reversely bent upon itself to form an upwardly projecting flange l4 likewise further reference 2 spaced from the back plate. At iii are indicated certain cutout configurations by means of which the hanger is attached to a cooperating fixture, which in turn is secured to the door. No is made to this feature as it forms no part of this invention.

The upper edge of the flange M is defined by a cutout portion comprising two straight converging sides l9 merging with a curved portion 20. An eccentric bearing pin I6 is provided with threads I! at one end and extends between the rear plate and the flange M, as is clear from Figure 2. The central portion of the shaft or pin I6 is provided with an eccentric portion 2| of circular cross-section and of a length so as to lie between the back plate and the inner face of the flange M, as clearly shown in Figure 2. Rotatably mounted on the eccentric portion 2! is a bearing sleeve 22.

In manufacturing this hanger the plate I0 is blanked out in a press so as to have a defining peripheral shape comprising integral triangular and truncated triangular portions, as is clear from the drawings. In the same blanking out operation the openings l5 are cut, as are the two circular holes in the rear wall through which the pins l3 and I6 pass. The flanges H and M are then formed. The hole to be threaded to receive the front end of the pin l3 and the curved seat 20 with the inclined sides IQ for the flange M are then cut by means of punches, which can pass through the two holes in the rear wall previously mentioned, which act as guides or a template for proper alignment of the hole and seat in the flanges H and M respectively. The hole in the flange I l is then tapped and then the piece to form the inclined sides 19 is cut out if it was not cut out before the curved seat 20 was formed. This insures proper alignment of the parts.

A very ractical feature of this invention is concerned with the above stated seat 20 for the front end of the eccentric pin which permits as sembly in a simple hanger bracket of the type disclosed, which would otherwise be impossible if the assembly pin were seated at both ends in closed circular seats. In assembling the eccentric pin IS with the bearing sleeve 22 mounted thereon, the eccentric pin is in a position which is from the position in which the pin is shown in Figure 1, in which case the side of shorter radius can be passed over the notch formed by the inclined side 20 while the threaded end I1 is being inserted in the hole in the rear wall Ill. The front end of the pin can then be dropped down into the curved seat 20 and the eccentric pin locked in adjusted rot means of the nut l8. 7

An advantage of this construction is that after the hangers, of which there are usually two or more for each door, are mounted on the hanger bar so that the hanger wheels l2 ride on its upper edge, the roller sleeve 22 can be adjusted to the proper clearance with the underside of the rail by loosening the nut'l8 and rotating the pin H3 in either direction. The eccentric portion 2i as ational 7 position by away from the underside of the hanger bar, thus providing the sleeve and the bar. locked in position by means of the nut l8.

This overall adjustment is of considerable practical importance in view of the, fact that if the .10, ove the sleeve towards and" proper clearance between this;

When properly adJ'iIsted'it-is roller sleeve I8 is at a fixed distance from the.

hanger wheel 52 an vide just the right clearance with the hanger bar. This is a ractical impossibility in view of the fact that the hanger and hanger barparts vary enough in manufacturing tolerances to result in either too loose or too tight a fit between the hanger and the bar. Thus the structure herein disclosed provides a very inexpensive and efiective for wear of the partsas they occur.

From the above description-it will be apparent to those skilled in the art that the subject mateffort must be made to pro ter of thisinvention is capable of some variation" from the form presented herewith for illustrative purposes. I do not, therefore, desire to be strictly of illustration but rather by the claims granted me. i

What is claimed is:'

1. In a door hanger a supporting platehaving one edge reversely bent to form a parallel flange, said plate having an aperture therethrough and said flange having a curved seat in alignment with said aperture and open at the edge of said 4 flange and an eccentric pin supported in said aperture and on said curved seat.

' 2. In the combination of claim 1, said eccentric pin having a sleeve rotatably mounted thereon and lying between said plate and. flange.

3. A door hanger of the type described comprising a supporting plate having a pair of opposite ends reversely bent to form'parallel flanges, a roller lying behind one of said flanges and a pivot pin therefor passin through said plate and "adjacent flange, an eccentric pin passin at one end through said plate and resting at its other end on an open sided seat formed at the edge of said flange whereby said eccentric pin is pro- ]15 ,vi'ded, with a bearing at each end.

4. A door hanger comprising a supporting plate having an'opposite pair of edges reversely bent to form .a pair of opposed, flanges forming channel ends for said plate, a hanger roller journaled on a pivot pin in one of said channels, a, roller sleeve and-a removable eccentric pivot pin for supporte ing said sleeve andbeing supportedat one end in'said plate and at the other end in said other flange." V

5. In the combination of claim 4 the support,

in the flangefor the flange edge;

'6. In the combination of claim 3,- a sleeve rotatablymounted on said pin and lying between said plate and flange. T I
