Be it known that I, WILLIAM B., ARNOLD,

of North Abington, county 'of Plymouth, and State of Massachusetts, have invented an Improvement in Hinges',of which the follo'wing`i description, in connection with the' accompanying drawings, is a specification ,Y like lettersy on the'drawings representing like parts.

My invention is a new hinge, and has for its object the provision of a hinge having the general shape and ,advantages of a plug or doWel like hinge, while being exceedingly" cheap, strong, and light.

A number of dierent kinds of hinges have been proposed made'on the general principle` of pivoting together vtwo do'welsor 4sets .ofv dowels, the dowels to be inserted in the wood of the material to be hingedtogether and secured therein; but the high cost of Vmanufacture of these hinges as heretofore made has been practically prohibitive, and besides this', being turned from solid metal they have been very heavy and cumbersome. I have invented a hinge of this general character which is eX# ceedingly' light and maybe made with ex,- treme accuracy at a very slight cost, so as to be Within the reach of all, desiring such a hinge, my invention in its preferred'embodiment also possessing various other advantages which will be more fully pointed out in the course of the following detailed description, reference being had to the accompanying drawings illustrative of preferred emlmdi-V ments of my invention, andthe latter willibe more-particularly defined in the appended claims. l

In thedrawings, Figure l is a perspective View of one form of Amy hinge; Fig. 2 is a top plan View of a hinge' of the samegeneral character slightly modified. Fig. 3 is a perspective View of a further modification. Fig'. 4 is a broken detail in vperspective to be referred to.

Referring to the drawings, it will be seenv 'that each of the hinges illustrated is made up of opposite pairs of leaves stamped. or bent in semieylindrical shape, so as together to constitute a hollow plug or dowel like member of the hinge, the two members being pivotally joined together at their pintle or turn- .ing-point.

. senti No, vonnis. un mail.)

each of which is stamped or bent to the shape of a semicylinder, each leaf being provided at i-ts'inner end with an ear a', having a shouladr a2, preferably formed on an arc of a circle concentricwith the pintle a3, and against the inner, sides of these ears a are similar ears orL o'f similar leaves a5, excepting that said ears argo-not stand out beyond their leaves, as is the case at theshoulders a2 of the inclosing ears a'. v

v In Fig. 2 the various parts are constructed the same as already described, excepting thatv -instead of having the ears arranged just as stated I have offset the inner ears ai?, so as to provide shoulders a7, and have correspondingly osetv or' separated the outer ears as,

the shoulders a9 thereof being considerably Ydeepenthan the shoulders a? .of the' form shown in- Fig; 1, the shoulders of o? acting as abutments to bear against the adjacent wood and act as self-centering devices for insuring that the pintles will be in accurate alinernent when a numberof the hinges are to be used together adjacent each other.

In my hingel the opposite leaves oi" each pluglike member constitute a single tube ex- ;tending to the pintle-ea'rs, these leaves being cut and stamped to form complementary parts of saidjtube and the two tubes Whengpivoted together at their ears forming a complete hinge; but I do not intend to restrict my invention to having both of the leaves of one tube precisely alike either in size or shape,

excepting thatwhen joined or formed together they shall make up onetube.

In Fig. 3 the'ears am a are brought closel f together and pivoted on one pintle a, this construction being preferable for the greatest strength and compactness, although sacriiicing to some extent certain. advantagespossessed by the other forms of my invention already explained.v

In View of the above description it will be readily understood that these hinges can be manufactured at very slight cost, the leaves being quickly and cheaplyv struck up ont of sheet metal (steel, brass', or other metal) on material'acoording to the use for which they are required and vquickly assembled and 4riveted or otherwise hinged together.

In case the hinges are made truly cylindrical they can be secured in place simply by IOO `section they can be similarly secured by making the hole ywith any usual mortising-machine, the plug-like ends being then inserted any other suitable means. In some situations, however, it is desirable that the leaves of these hinges shouldbe incapable of turning independently on their pivots,as shown in Fig. 4, and accordingly Iprovideinterlockin g portions in any suitable manner to prevent the leaves from getting out of relative position, one form of such-interlocking or holding device being shown in Figs. 2 and', where it will-be seen that I have bent atongue inwardly atthe edge of each leaf, said tongue being bent inwardly just sufficiently toV lap over and against the opposite edge, as is clearly shown in Fig. 3, the result being that neither leaf can possibly shift on the other leaf.

I do not claim, broadly, a plug or dowel like hinge, inasmuch as I am aware that it is old; Vbut myV main endeavor has beentode- ,Y vise aV hinge of this vvery desirableV general character which shall ybe practical and commercially feasible, and the hinge herein disclosed meets all the essential requirements so far as known to me, inasm uch as these hinges can be made with exceeding rapidity and at very low cost, while being at the same time unusually strong, very light, and at the same time they possess all the accuracy and neatnessV afforded by the expensive turned hinge.

`I do not limit my invention to the particu- .lar forms herein shown, inasmuch as very many other shapes, certain of which have been alluded to, and various modifications and changes may be resorted to within the n sitely-bent leaves against Vrelative. shifting movement, substantially as described.

2. A hinge, having hollow, plug or dow'el like members pivotallycounectedat their-inner ends, each of said members being composed "of twoV leaves oppositely bent to form complementary parts of a single tube extending'to'adjacent the pintle and terminating in opposite ears, the several ears of the two opposite tubular parts beingV pivoted together,

substantially as described.

3. A hinge, having hollow, plug or dowel like members pivotally connectedat their inner ends, each of said members being-composed of two leaves oppositely bent to form complementary parts of a'single tube extending to adjacent the pintle and terminating in opposite ears, the several ears of the two opposite tubularfparts being pivoted together, .and certain of said ears being offset to provide projecting shoulders, substantially as described.

4. A hinge, having hollow, plug or dowel like members pivotally connected at their in- Vner ends, each member being in the form of a single tube extending to'adjacent the pintle and terminating in opposite ears, said several ears of the two opposite single tubular parts beingV overlapped and transversely pivoted together, and all of said ears being offset and circular in shape to provide shoulders for self-centering the hinge when in operative position, substantially as described'.

, 5. A plug-hinge whose members are cylindrical in. shape, said members containing leaves pivoted together at their inner ends and extending in opposite directions, one or more of said leaves being stamped or bentin semicylindrical form, substantially as dcscribed.

6. The herein-described hinge, having a member formed with opposite leaves extending from the hinge-pintle and stamped or bent in semicylindrical form, together constituting a tubular plug-like end, substantially as described.

In testimony whereof I have signed my name to this specification in the presence oi' two subscribing witnesses.

VILLIAM B. ARNOLD.
