JOHN TINKEY, OF NEW HAVEN, CONNECTICUT.

IMPROVED DOOR-GUARD.

Specification forming part of Letters Patent No. 58,916, dated OCtOlJLl 1G, 1866.

To all whom it may concer-n:

Be it known that I, JOHN TINKEY, of New Haven, in the county of New Haven and State ot'Conneeticut, have invented a new and useful Improvementin DoorGnards5 and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description ot' the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a top view; Fig. 2, a side view; Fig. 3, a longitudinal central section Fig. 4, the keeper as fixed tothe door; and in Fig. 5, a sectional view to illustrate its operation.

My invention is designed more particularly to be placed upon the base, back ot' the door, to prevent the door from striking the wall; and my invention consists in the construction ot the guard so that while it prevents the door from striking the wall it will, if required,

. retain the door in an open position.

To enable others skilled in the art to construct and use 1n y improvement, I will proceed to describe the same as illustrated in the aecoinpanying drawings.

A is a head, fixed by a shank, B, of any desired form, to the base. Upon the side of the head A, I insert a bolt, G, having an inclined flange, d d', upon both sides, thinner than the bolt itself. (See Figs. 1 and 2.)

A spiral spring, as denoted in blue, Fig. 3, holds the said bolt C out, as in the position seen in Figs. 1 and 3, againsta face-plate, D. (See Figs. 2 and 3.)

E is the keeper, fixed upon the edge of the door F. (See Fig. 4.) As the door is thrown open the keeper E strikes the inclined iiange d at f, forcing the bolt back, as denoted in red, Fig. 3. As soon as the keeper has passed onto the bolt, the bolt is thrown forward into a mortise, I, in the keeper, (see Fig. 5,) the incline d entering the narrow portion yi of the inortise. The shoulders a a strike the holt C and prevent its going farther back. The incline d' bears against the keeper with sutiieient force to ordinarily retain the door in open position, but so that the door may be easily pulled away from the guard, the keeper forcing the holt into the head to permit it to pass.

Although designed more particularly for a door-guard, yet my invention may he used to advantage for retaining doors in a closed post tion which do not require positive securityas doors ct' presses, closets, &e. To do this, place thc bolt in the jamb ot' the door, the keeper on the edge of the door, so as to operate to stop the door when it shall have been closed suiliciently close, as described for holding the door in an open position, the door to be opened by means of the usual knob or equivalent therefor placed upon similar doors.

I do not broadly claim a door-guard constructed so as to stop and hold the door, so that the door may be released from the l1old ing by simply pulling the door from the stop.

Having, therefore, thus fullyY described inv invention, what I claim as new and useful, and desire to secure by Letters Patent, is-

The combination of the holt G, constructed 4with flanges d and d', so as to forni shoulders on the said bolt, and keeper ILeonstructed and arranged to operate substantially in the manner and for the purpose set forth.

JOHN TIXKEY.
