` UNITED STATES' PATENT ma.

FRANK W. TIESING, OF NEW HAVEN, CONN., ASSIGNOR TO THE SCHOLL- HORN 87 TIESING MANUFACTURING COMPANY, OF SAME PLACE.

HINGE.

SPECIFICATION forming part of Letters Patent No. 239,201, dated March 22, 1881.

Application filed January 31, 1881. (Model.)

To all whom it may concern:

Be it known that I FRANK W. TinsING, of New Haven, in the county ot' New Haven and State of Connecticut, have invented a new Improvenient in Concealed Hinges; and I do same, and which said drawings constitute part y of this specification, and represent, in

Figure l, a front View as in the open condition; Fig. 2,an end or top view with the parts in their closed condition Fig. 3, a vertical section on line XX; Fig. 4, a perspective view of' the shoe.

This invention relates to an improvement in that class of hinges which are used for hanging coach or carriage doors, and commonly called concealed hinges, from the fact that when the door is closed the hinge is entirely hidden. These hinges consist of a plateat` tached to the door-post, a second plate attached to the door, with a curved arm extendingtherefrom through a slot inthe plate, and hung to a pivot on `the back ofthe plate, and nearly in line with its front edge, so that when the door is opened it turns on the said Apivot entirely away from the door-post, the pivot being con-r cealed within the post.

Itis desirable at times to remove the carriage-door.4 Formerly this could only be done by removing the screws from the plate on the door-post and taking the hinge bodily from its place. This is not only difficult, but generally very inconvenient.

The object of this invention is the construction of the hinge so that the pivot and its sea tthat is, the operative partsA of the hinge-may be entirely removed without detaching the plate from the door-post. To this end the invention consists in the construction as hereinafter described, and particularly recited in the claims.

A is the plate'of the door-post, and B the plate for thedoor, both of the usual form. The

plate B is provided with an arm, C, curved in arm, E, extends, in the usual manner, for the support ot' the arm C, and to which the said arm is usually pivoted; but instead of pivoting the arm C to the arm E, It the arm C to a shoe, H G. (Shown det-ached in perspective, Fig. 4.) This shoe has a horizontal flange, G, at the bottom, and a similar flange, H, above, the space between corresponding to and so as to receive the arm C of the plate B. This shoe is also titted with a lug or stud, L, on its under side. Into the shoe the arm C is hung by a pivot, a, which extends through the arm, as seen in Fig. 3. Atthe outer or front edge ot' the plate A a vertical slot is made, opening above and below the slot D sufticient to permit the arm C, with the shoe F thereon, and

its stud L, vto be passed in, as seen in broken lilies, Fig. 3. The arm E is provided with a recess to receive the stud or lug L, and so that when the shoe has been fully inserted, or so as to come ush with the plate A, the lug or stud L will drop into its corresponding cavity inthe arm E, which, together' with the tit of the shoe in its slot in the plate A, is sufficient to hold the shoe in its place; and when so in place theplate B and the door thereto attached is turned in the usual manner, the arm C working through the slot D.

The vertical slot for the insertion ofthe arm with its shoe would leave an opening through the plate. To ill this opening I hang therein a closer, P, hinged so as to turn up, as seen in broken lines, Fig. 3, to open the'slot, or turned down to fill it,.as seen in Figs. l and 3; and that it may be held in eitherits closed or open position, I provide aat spring, R, on the back oi' the plate A to bear upon the closer P above its pivot, and also cut a notch., S, in the plate A at the side ofthe closer, as a convenient means for opening the closer.

When it is desired to remove the door or separate the two parts itis only necessary to raise the closer P and lift the arm C, with its shoe, from its engagement with the arm E.

I do not broadly claim a coach-hinge having the part attached to the door detachabl from the part attached to the post.

I claimi l. The herein-described concealed hinge, consisting of the plate A, constructed with the a2 2239,2'oi

Vertical slot opening from said horizontal slot, combined with the plate B. with an arm, G, extending therefrom, and pvoted in the shoe H, said shoe H fitted for insertion through the 15 'vertical slot in the plate A and engagement with the arm E, and with the closer P for the vertical slot,vsubstantially as described.
