MANUFACTURE OF HINGES SPECIFICATION forming part of Letters Patent No. 376.702, dated January 1-1, 1888.

Application filed March 24, 1887.

following specification and claim and illustrated in the accompanying drawings, in-

which- Figure 1 is a plan view of a blank. Fig. 2 1s a perspective view of a hinge-section partly formed. Fig. 3 is an end view of two hingesections partly formed. Fig. at is an end view of a hinge. Fig. 5 is a plan view of a hinge. Similar letters indicate corresponding parts.

In making the hinge'a blank is formed of suitable material-such, for example, as sheet metal. This blank may be of a length sufficient to make, several hinges and a width about equal to twice the required width of a hinge-leaf. The blank is readily formed by forming, punching, or stamping a suitable strip of material, so as to provide said strip with leaves A, with tongues B, and with apertures O, as seen in Fig. 1, said tongues and apertures being arranged alternately in a sin- 0 gle line occupying the longitudinal center of.

the blank. The strip so formed iscut into suitable lengths, as indicated by the trans verse dotted lines in Fig. 1. By forming the tongues B and the apertures 0 respectively 'equa1 to oneanother the several lengths or pieces cut from the said strip of material can be readily madeto correspond to one another. The pieces cut from said strip are then bent longitudinally through the central line of al- 0 ternating tongues and apertures,- whereby said pieces or sections are brought to the position or form indicated in Fig. 2. The tongues B are thereby caused to form the knuckle of a hinge-section. The tongues B of one hinge- 4 5 section are then placed into the apertures O of another hinge-section, and apin, D, Fig. 3, is placed into engagement with said tongues B.

The leaves A A of the respective hingesections are then brought toward one another Serial No. 232,288. (No model.)

or into contact with one another, as indicated in Fig. 4. A hinge is thus formed consisting of leavesswinging about a pin or pintle, D. A suitable die or press of any well-known construction can be used to bring or press the leaves A A to the position shown in Fig. 4..

The leaves A should be secured to one another by suitable means, such as attaching or fastening devices E. Said fastening devices E may consist of screws or rivets; or other means may be employed to secure the leaves A to one another. Thus, for example, the

leaves A may be welded or soldered together or secured to one another by any suitable means. By making the leaves A symmetrical or equal to one another and securing said leaves to one another said leaves will strengthen or re-enforce one another,thus securing a strong and durable hinge. I r

The hinge can be secured in position by ordinary means, such as screws or fastening devices passed through apertures F in the leaves A. p r

I am aware that hinges have heretofore been made by cutting from two separate strips of metal a number'of blanks or sections of like form, the sections cut from one strip being provided with apertures, and thosecut from the other strip having tongues, then bending each section transversely througlrits tongue or aperture, as the case may be, to

form a knuckle, and connecting the two parts by a hinge-pin without securing the leaves of each part together. This, however, I do not claim, and my invention differs therefrom in cutting both parts of the hinge from one strip of metal having a series of alternating tongues and apertures, then bending these sections longitudinally through the center of said alternating tongues and apertures, and securing the leaves of each'part together.

WhatI claim as new, and desire to secure by Letters Patent, is- I The herein-described method of making a hinge, which consists in providing a blank with leaves A, having a central'longitudinal series of alternating tongues, B, and apertures C, bending a section of said blank longitudinally in a line passing through said tongues and apertures,then engaging the tongues of In testimony whereof I have hereunto set one. section in the apertures of a correspondmy hand and seal in the presence of two subing section, placing a pin or pivot into en-' scribing Witnesses.
