PORTLAND, MAINE.
IMPROVEMENT IN DOOR-CHECKS.
Specification forming part of Letters Patent No.
179.308, dated June 27, 1876; application filed March 10, 1876.
To all whom it may concern:
Be it known that I, THOMAS HILL, of Port- .and, in the county of Cumberland and State of Maine, have invented a new and Improved Door-Fastener; and I do hereby declare that the following is a full, clear, and exact description of the same.
The invention is ,an improvement in the class of adjustable fastenings for doors which will allow a door to be opened slightly, as may be required for ventilating the apartment, or for communication between a party within and a party without the apartment. It is more particularly an improvement in the class of fastenings formed of a slotted plate attached to thejamb, and connected with a sliding bolt attached to the door.
The improvement consists in pivoting the slotted plate in a recess of the jamb, the same being otherwise constructed and arranged as hereinafter more fully described and definitely claimed.
In the drawing, Figure 1 is a perspective view, showing my invention applied to a door. Fig. 2 shows the position assumed by the slotted plate when not in use.
The metal plate A is pivoted in the recess 1), formed in the rabbet oithe jamb or doori'rame B. The plate hangs vertical in said recess when not in use, and is thus out of the way, and constitutes no obstruction to the opening and shut-ting of the door or the passage through the doorway, while instantly accessible and available for use in securing the door. The plate is provided with a lengthwise slot, at, and a series of notches, c, is formed in the edge of the slot to receive the head (1 of a sliding bolt, 0, which is attached to the door D.
The plate may be turned on its pivot, and thus raised to a horizontal position, as shown in Fig. l. The bolt O is slid forward till the head 01 enters the enlarged portion of the slot 0. at the inner or pivot end of the plate, when the door may be opened as far as the length 'of said plate permits; but, whether opened more or less, it is secured against forcible entry of any one from the outside, since the notched head of the bolt cannot be withdrawn from the slot except the door is first closed.
When the door is closed, the head of the bolt passes back into theenlarged portion of the slot, and, the bolt being slid back, the plate drops into the recess 1) in the janib.
The function of the notches in the edge of the slot is to enable the door to be set and held open more or less, according as the head of the bolt is engaged with one or the other of them. It is essential the plate shall be so secured in the recess b of the jamb that it may not be readily removed by any one desiring to effect an entrance. To this end rivet the head of the plate A to a small plate, a, and give the said head such form that when the plate Ais in either a horizontal or vertical position it will cover and protect the screws by which the plate is secured to the jamb. The head of the plate is, however, cut out on its sides in such manner that the screws are exposed when the plate A is adjusted at an angle of about forty-five degrees to the jamb.
The device, as a whole, constitutes a cheap, but eflicient, means for securing a door partly open, and without the necessity of keeping it entirely closed.
What I claim is- The plate A, pivoted in a recess, 1), ol' the door-jamb B, as and for the purpose specified, and provided with the notched slot to, to adapt it for connection with the sliding headed doorbolt G, as shown and described.
