Appnmon nea May 3,1893. serai No. 472,579.1 (No man.)

T0 all whom it may concern:

Be it known that we, THOMAS CORSOADEN and FRANKLIN HOLLAND, citizens of the United States, residing at NeWBritain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Antifriction-Hinges, of which the following is a specification.

Our invention relates to improvements in anti-friction hinges, and the chief object of4 our improvement is to provide a cheap and eflicient Way of securing the anti-friction devices to the leaves of the hinge. K

In the accompanying drawings: Figure 1 is` a front elevation of a hinge constructed in accordance with our improvement. Fig. 2 a vertical section of one of the knuckles of said hinge on the line a; of Fig. l, together with an elevation of a portion of the hinge pintle and anti-friction devices secured to said knuckle. Fig. 3 is a like view of the same in a hinge having a plain knuckle. Fig 4 is a detached vertical section of the attaching sleeve for the anti-friction devices, and Fig.

5 is a like sectional view of the sleeve in itsY final form.

A A designate the leaves of the hinge which may be of any'ordinary construction. As

shown in the drawings, it is a wroughtiron hinge with its knuckles 5 and 6l corrugated or beaded, but our invention is applicable'to ordinary hinges having plain knuckles.

7 designates anti-friction devices whichl consist essentially of two washers, either withor without an inclosed washer, rollers, balls, or other anti-,friction devices. l cient space is left between part of the knuckles 5 and 6 to insertrthese anti-friction devices particular hinge shown.

A suffi! which is inserted within this chamber 8 and enlarged at its end so-as to secure it to the 5o `end'of the knuckle as shown in Figs. 2 and 3, even though the pintle 9 be removed.

.- InFigs. l andv 2 the chamber 8 is formed Within the hollow of one of the beads or corrugations, but this is only incidental to the An overhanging chamber can be readily formed in the knuckle of any ordinaryV hinge, as for example, the chamber 8S in the plain knuckle 55 as shown inF-ig. 3, the anti-friction devices being se- 6o cured therein in the same manner.

In order to assemble the parts, we first form the projecting end of this sleeve 10 with cylindrical sides on its exterior, while the excess of metal is upon the inside as shown in 6 5 the detached sleeve, Fig. l. This sleeve is\4 long enough to pass through both of the antifriction washers and is preferably provided with a head 1l which is let into the outer side of the outer washer, but it is evident that if '7o desired this sleeve might be made integral with the outer washer. After the sleeve has been formed as shown in Fig. 4, the anti-friction devices are placed together on said sleeve .and its projecting endis placed within the vchamber 8 or 88. A pin or punch is'then driven 'through the sleeve so as to `forcev` the` excess of metal Ewhich is upon theinside of Y the sleeve outwardly and form -the enlarged end as shown in Figs. 2, 3 and 15, thereby changing 8o the' metal at the projecting endof the sleeve from the form shown in Fig. ttothat shown in Fig. v5- in Whichthe exces'sof metal is thrown from the inside ofgthesleeve to the outside asshown, and theanti-friction devicesJthereby secured in g-"plac`e so that they willnot be accidentally. detached from the hinge leaves.

Other means may be devised for assembling the parts, but the foregoing are thebest go means known to us for'assembling a holding sleeve having an enlarged end within a chamber having overhangingside walls.

By our improvements, we are enabled to cheaply and conveniently secure the anti-friction devices to the ends of` such knucklesas may be desired and in such a manner that and having its end enlarged fol` holflng the to theywill not be liable to accidental detachparts in pleceubstantially as descmbed and ment. for the purpose specified.
