2 Claims.

This invention relates to a hinge device and, more particularly, to a hinge device to be used with commercially known overhead garage doors, such doors consisting of a plurality of panels 5 hinged together, to enable the same to slide along the vertical and horizontal portions of the guide tracks for the door.

The primary object of the invention is the provision of a hinge device of simple but substantial construction, which may be manufactured at relatively low cost and the component parts shipped in assembled relation.

Another object of the invention resides in the novel manner of forming the plates, with turned up ears and bearings whereby the plates may be economically hinged together and the proper bearings provided for the roller shaft.

A feature of the invention resides in the novel manner of stamping the plates so that a plurality of strips are provided which are subsequently rolled back upon themselves to provide the necessary bearings for the shaft and the necessary ears for the hinge pintles.

Another feature of the invention resides in striking the shaft bearings directly from one of the plates and arranging said bearings in spaced relation with the plates so that the roller carried by the shaft may have proper action in the guide track of the door.

With these and other objects in view, the invention will be better understood from the following detailed description, taken in conjunction with the accompanying drawing, wherein:

Figure l is a front elevation of the hinge device.

Figure 2 is a side elevation of the hingedevice.

Figure 3 is a perspective view of the lower plate.

Figure 4 is a perspective view of the upper plate.

In the drawing, the numerals I and 2 designate a pair of metal plates the former hereinafter identified as the upper plate, and the latter as the lower plate, although I wish it to be understood that this relation of the plates may be reversed. 45 As shown in Figure 4, the plate i is stamped to provide a slot 3 defining a pair of side strips ,4 and 5 which are rolled back upon themselves to form the cylindrical ears 6 and 'l.

The plate 2 is stamped and out along the lines 89 to provide the end strips and II, and the intermediate strip l2. The intermediate strip is rolled back upon itself to form a cylindrical ear 13 which is adapted to be arranged in the slot 3 of plate I and aligned with ears 6 and l to receive the pintle l of the hinge thereby forming a hinge connection between the upper plate and the lower plate.

The end strips in and H are bent at an angle to the plate 2 toprovide the yokes l for the purpose of spacing the bearings l6 thereof from the body of the plate 2. The bearings I6 are formed by rolling back the extreme end portions of the strips Ill and I I. These bearings or tubular members I6 have relatively smooth interior surfaces so as to allow the free rotation of the shaft l! journalled therein. This shaft has both ends protruding beyond the bearings, and on one protruding end is mounted a roller l8 adapted to travel in the guide track of the overhead door. The roller E8 is fixed to the shaft and to provide the rotatable action of the roller l8, the shaft ll turns in the bearings l6. To provide an assembled relation between the shaft and the plate 2 in the shipment of the article, the remaining protruding end of the shaft is upset, as indicated at l9.

As the roller 18 is fixed to the shaft to provide an abutment for one end of the shaft against the bearing l6 and the upset end is is capable of abutting the remaining bearing l6, attention is called to the fact that the shaft ll is held in assembled relation with plate 2 but is capable of a certain degree of longitudinal movement within the bearing for allowing proper adjustment of the roller It in the guide track of the overhead door.

The hinge device is usually connected to a pair of adjacent panels of the garage door with the pintle M arranged at the contacting edge surfaces of the adjacent panels, with the result that the panels may swing relative to each other.

Due to the novel manner of mounting the roller H3 in close proximity to the pintle Id and allowing the same to have a sliding relation with the hinge plates, the roller may be effectively associated with the usual guide track of a garage door.

Due to the formation of the plates, it will be appreciated that they may be readily stamped into their formation at very little expense, and the bearings and ears subsequently forced into formation, thereby materially reducing the cost of manufacture. Y

The final manufacturing operation relates to mounting the roller IS on the shaft, slipping the shaft through the bearings l6 and upsetting the end thereof. Thus it will be appreciated that I have designed a very inexpensive type of combination hinge and roller for use on overhead garage door constructions.

What I claim is: 1. In a hinge having a pair of plates provided with knuckles and a pintle passing therethrough:

a support on one of said plates comprising a.

2. In a hinge having a pair of plates provided with associated pintle receiving knuckles: a support on one of said plates comprising a plurality of aligned bearing sleeves extending laterally from and confined Within the marginal edges of said plate, said sleeves consisting of similar integral rolled strips in spaced parallel relation, the

axes of said sleeves being offset from the plate and from the axis of said pintle receiving knuckles; and a roller carrying shaft supported in 10 said sleeves.
