SPRING-HINGE.
Application filed April 15, 1913, Serial No. 781,141. Renewed July 15, 1914:
To all whom it may concern Be it known that I, EMIL BoMMEn, a citi- Zen of the United States of America, residing in New York, in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Spring-Hinges, of which the following is a specification.
This invention relates to certain improvements in single-acting springhinges of that class in which one leaf is bent up integrally with the barrel from a single blank of sheetmetal, the leaf thus bent up consisting of two layers which are formed of extensions of the barrel and which are rigidly connected with each other.
The invention will be more fully described hereinafter and finally pointed out in the claims.
In the accompanying drawing, Figure 1 represents a rear-elevation of my improved single-acting spring-hinge, Fig. 2 is a horizontal section of the same on line 2, 2, Fig. 1, and Figs. 3 and at are respectively a detail section showing the upper portion of the barrel and its leaf, and a side-elevation of the same, drawn on an enlarged scale, Fig. 5 represents a partly bent-up blank, showing the upper and lower extensions and screw-holes for connecting the layers of the web, and Fig. 6 is a horizontal section on line 6, 6, Fig. 5.
Similar letters of reference indicate corresponding parts throughout the several figures of the drawing.
Referring to the drawing, Z) represents the barrel, (Z the flanged leaf of the springhinge, which is made of a single thickness of sheet-metal and provided with perforated ears (Z bent up at right angles to the leaf, and (Z a reinforcing flange extending between the ears vertically along the inner edge of the flanged leaf d. The pintle 79 passes through the perforations of the ears (Z the center of the barrel Z), the adjustable springholder 0, its bushing e, and the fixed springholder 0 and its washer 6 From the barrel 79 extend two overlapping layers 6 b which are, like the leaf (Z, provided with screw-holes, the thickness of the two layers of the barrelleaf together corresponding approximately to the thickness of the flanged leaf (Z. The two layers 6 and b of the barrel-leaf a extend above and below the upper and lower edges of the barrel, up to a level with the upper and lower edges of the Specification of Letters Patent.

erial No. 851,227.
ears (Z of the flanged leaf (Z. The upward and downward extensions of the layer 5 of the barrel-leaf a are wider than the upward and downward extensions of the layer 25 and are slightly nicked or slitted, as at 1, adjacent to the upper and lower edges of the barrel, the greater width of the upward and downward extensions of the inner layer 5 serving to provide sufficient stock for the flaps r and for bending the same around the adjacent recesses o in the edges of the extensions of the layer 6 and for clenching the edges r 9 of the two layers 6 and 5 into rigid connection with each other flush into the plane of the connected layers 6 and The layer 6 is recessed at the edge r of its upward and downward extensions to receive the bent edge r of the layer 6 which is reduced in thickness at the bend. The screw-holes Z2 for attaching the spring-hinge to the door consist of smaller holes in the layer 6 which holes correspond in location with the larger holes in the layer 5, the holes of the layer 6 being made smaller than the diameter of the screw for which they are intended, the surplus stock, shown by dotted lines in Figs. 1 and 5, around the smaller holes 6 of the layers 5 being then thrown up in forward direction into the larger perforations 6 of the layer 5 and upset into the same so as to form screw-holes of the required size and shape for the shanks and heads of the screws. By thus upsetting or swaging the surplus stock at the screwholes 6 of the layer in an opposed direction to the clenched connection of the inner edges 1, r of the upper and lower extensions of the two layers 5 and 6 a reliable rigid connection of the two layers of the barrel-leaf a of the spring-hinge is obtained, by making use of integral parts of the layers for connecting them together and overcoming thereby the use of separate rivets and the objectionable appearance given by them to the leaf.
1 claim:
1. In a spring-hinge, a barrel provided with a leaf bent up in two layers integrally with the barrel, said layers having extensions, one extension having its edge adjacent to the barrel bent and clenched around the other extension at its edge adjacent the barrel.
2. In a spring-hinge, a barrel provided with a leaf consisting of two layers bent up holes of said first layer in a direction oppo- Copies of this patent may be obtained for five cents each, by addressing the site to the bent and clenched edges of the extensions of the first layer over the second layer, for rigidly connecting the layers to- 1;, gether.
In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing Witnesses.
