Patented Apr. s, 1930 PATENT OFFICE JOSEPH FISHER, F QBEAJSON' FALLS, CONNECTICUT HINGE Application led January l2, 1928. Serial No. 246,363.l
This'invention relates to an improvement in hinges of the type Commonly known as cabinet hinges.
The object of this invention is to produce a superior and durable hinge constructed with particular reference to providing, at allow,
cost for manufacture, simple reliable and attractive means for retaining the pin therein.
lfVith this object in view, my invention conlo sists in a hinge characterized by having the end knuckle of one of its leaves formed with an integral combined finishing and pin-retaining finger folded 'over at a right angle to close the end of the pin-channel in the said lo knuckle.
My invention further consists in a hinge i characterized as above and having certain details of construction and combinations of parts as will be hereinafter described and particularly recited in the claim.
lin the accompanying draw-ings:
Fig. l is a face view of a strap-type hinge embodying my invention;
Fig. 2 is an edge view thereof;
Fig. 3 is a top or plan view thereof;
Fig. l is a longitudinal section on the line iF-4l of Fig. 1;
Fig. 5 is a detached view in elevation of the left-hand leaf of the hinge shown in the preceding gures;
Fig. 6 is an edge view thereof;
Fig. 7 is a top or plan view thereof;
Fig. 8 is a view in elevation of a butt-type hinge embodying my invention;
Fig. 9 is an en'd view thereof; and
Fig. 1Q is a top or plan view thereof.
',lhe hinge shown in Figs. 1 to 'Z inclusive of the drawings is of the form commonly known als strap type, since it is designed to be 1nstalled atwise upon the outer face of a cabinet and cabinet-door. The hinge proper may be of any approved form and as herein shown consists of two complementary leaves 15 and 16. each provided with countersunk screwholes 17. The leaf 15 is out and folded in the usual manner to form three offsetting knuckles 18, 19 and 20, between which are positioned the knuckles 21 and 22 of the comple- `mentary leaf 16. Passing axially through the knuckles is the usual pin 23 2o-extensive in length with the length of the leaves 15 and 16 aforesaid.
At a point opposite the plane of the respective leaves the knuckles 18 and 2O of the leaf 15 are respectively formed with integral rounded. combined finishing and pin-retaining fingers 2l and 25 which, after the insertion of the pin 23 in the knuckles, are folded over toward the said leaf so as to respectively close the upper end of the knuckle 18 and the lower end of the knuckle 20.
Preferably and as indicated in Figs. 5, (i and 7, the lingers 2l and 25 are produced by milling away the knuckles of which they form a part, whereby they are of plano-conven form in cross-section. When folded over at a right angle, as shown in Figs. 1 to l inelusive, the convex side of the said hngers merge naturally into and complement the curvature of the knuckles, so that an extremely attractive hinge is produced having knuckles with symmetrically-rounded terminals.
'lhe form of hinge shown in Figs. 8 to 10 inclusive is of the type known as a butt-f since it is designed for use between the edges of a swinging member and the opening therefor in the manner of ordinary doors. The hinge referred to corresponds in all respects to that shown in Figs. 1 to Z inclusive with the exception that itslingers 24 and 25 are diderently positioned on the knuckle. ln the strap-type hinge Vpreviously described the tingers 2l and 25 are positioned so as to fold inward toward the plane of the leaves, whereas, in the butt-type hinge now beingdescribed, the corresponding fingers are so positioned that when folded they will extend inward at a right angle to the plane of the leaves, this being made necessary by the fact that dierent portions of a butt are exposed after installation. The same numerals have been applied to the corresponding parts of both types of hinges illustrated.
While l have shown and described the iingers 24; and 25 as having plano-convex form in cross-section, l wish to have it understoodv that I do not limit myself thereto, as it is obvious that the ngers may be uniform in crosssection, or of various other forms.
I claim: A A hinge comprising a pair of complementary sheet-metal leaves respectively folded at their adjacent edes to form spaced-apart tu- 5 bular hinge knuc les, substantially cylindrical in exterior form; a pintle extending through the said tubular knuckles for pivotally-coupling the two said leaves together; and a combined finishing and pintle-retainm ing finger forming an integral extension/from the outer end of one of the said knuckles and having substantially-parallel sides, and folded over the outer end 0f the said knuckle at a right angle and of a length suiiicient to snugly overlie and close the pintle-receiving opening in the said knuckle, and merging symmetrically into the cylindrical exterior form thereof when so foldedthereov/er at a right angle. j In testimony whereof, I have signed this specification.
