(N 'MOd L) I CHARLES E. DUCK, OF BALTIMORE, MARYLAND.

DOOR-FASTENER.

SPECIFICATION forming part of Letters Patent No. 635,530, dated October 24, 1899.

Serial No. 726,651. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES E. DUCK, a citizen of the United States of America, and a resident of the city of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Door-Fasteners, of which the following is a specification.

This invention relates to door-fasteners which may be used in case of, emergency where there is no bolt or lock to the door or the lock is out of order.

The object of this invent-ion is to provide a simple and convenient device of this character which may be portable and can be readily applied to serve as a temporary lock for a door as occasion or emergency may demand.

The invention consists of a door-fastener as hereinafter set forth and claimed.

Referring to the accompanying drawings, in which similar numerals of reference refer to like parts, Figure 1 is a view in perspective of a portion of a doorand door-jamb, showing the fastener in locked position. Figs. 2 and 3 are detailed portions of the fastener. Fig. 4 is a plan View showing the portions of the door and door-jamb in horizontal section and the fastener in locked position. Fig. 5 is a modification of the invention shown as permanently secured to a door-jamb. A

In carrying out this invention a door fa'stener is provided consisting of two partsa bar which can be secured to the edge of a door-jambby forcing one end thereof into the door-jamb, the bar extending between the edge of the door and the jamb when the door is closed and projecting into the room. The other part of the fastener consists of a locking device in the shape of a short arm or bar having one end adapted to be movable endwise on the bar projecting into the room and also so connected to said projecting bar as to permit the locking device to be tilted thereon and bind on said bar, whereby the locking device acts as a wedging-lever between the door-jamb and the bar projecting into the room to lock the parts in place and hold the door in locked position.

In constructing the fastener a bar 1, of metal, is employed having at one end a wedgeshaped projection 2, at right angles to the shank or main portion of the bar 1, and having a sharp edge 3, which is forced into the wood of the edge of the door-jamb. In conjunction with the bar 1 is employed a locking device 4, which consists of a short arm 5, preferably curve-shaped and having an enlarged end or head 6, provided with a passage-way 7 larger than the thickness of the bar 1, so that the head 6 can not only be moved freely over the bar 1, extending through the passage-way 7, but also so that the locking device 4 may be tilted or rocked on the bar 1.

It will be noticed that the ends of the passage-way 7 are provided with edges, the edge 7 of the inner end and the edge 7 of the outer end, diagonally opposed to each other, being brought to bear against the sides of the bar 1 when the locking device 4 is tilted thereon.

The fastener is used as follows: A door 9 being open and the bar 1 being held against the door-jamb, the sharp edge 3 of the wedgeshaped end 2 of the bar 1 is driven or forced into the door-jamb S by the closing of the door and pressing of the edge 3 into the jamb 9, a portion of the bar 1 extending between the door and door-jamb and the remaining portion projecting some little distance out from the inner side of the door-jamb, the View in Fig. 1 being on the inside of the door and door-jamb. The door being closed, the bar 1 will be wedged between the door and the doorjamb, and the wedge-shaped end 2 will be forced into the door-jamb. The locking device 4 is then slid over the portion of the bar 1 projecting from the door-jamb, the bar 1 extending through the opening 7 in the head 6 and the latter being tilted on the bar 1. As the locking-piece is pushed inward on the bar 1 the outer end of the curved portion 5 will be broughtto bear against the side of the door and the edges '7 7" of the passage-way 7 against the sides of the bar 1, and by applying force the edges 7 and '7 of the passageway 7 will be caused to bind against the bar 1 and the locking device 4 will be firmly wedged into place to lock the door and prevent it from being opened from the outside. The fastener may be released by applying force to the locking-piece 4 and knocking it backward on the bar 1, thereby disengaging it from its wedged position. The bar 1 may be then disengaged from the door-jamb and the fastener, composed of two pieces, carried away for future use.

It is obvious that the curved portion 5 of the locking-piece 4 may be straight instead of curved and extend at an angle to the head 6, the wedging action of the locking-piece still being permissible. The curved form serves to aid in wedging the locking-piece into locked position. The invention contemplates any construction in lieu of the head 6 and opening 7 whereby the locking device 4 may have a sliding and tilting and binding connection with the bar 1.

In Fig. 4 I have shown a modification of the fastener which only diifers from the construction already set forth in having a portion of the bar 1 curved or bent instead of straight. In this form a bar 10 is employed having a bent portion 11 so bent as to have one end brought around into contact with the doorframe. The object of this is to enable the fastener to be used, if desired, as a permanent bolt or fastener. The bar 10 is preferably a flat piece of metal which may be bent to the shape 11 in applying it to the doorframe, and the locking-piece is always at hand on the bent portion 11, so that the entire fastener may be left permanently in place to be used as a door bolt or fastener.

What I claim is 1. A door-fastener, consisting of a bar with an angular projecting portion at one end adapted to be forced into the edge of the doorjamb, in combination with a locking device having a head at one end, adapted to engage with and slidable upon said bar, and having a rocking movement thereon and diagonallyopposed edges adapted to bind on said bar, with a lever-arm portion adapted to wedge against a door, and lock said bar in position, as set forth.

2. Adoor-fastener,consisting of a bar adapted to project between the edge of a door and a door-jamb, and having an angular projection at one end, adapted to be forced into the edge of a door-jamb, in combination with a lock ing device consisting of a short curved arm, having a sliding and tilting and binding connection with said bar, whereby the locking device maybe wedged against a door and lock the bar in position, as set forth.

3. A door-fastener, consisting of a bar having a curved or bent portion, the straight portion being adapted to project between the edge of a door and door-jamb, and having an angular projection at one end, adapted to be forced into the edge of a door-jamb, in combination with a locking device consisting of a short curved arm, having a sliding and tilting and binding connection with said bar, whereby the locking device may be wedged against a door and lock the bar in position, as set forth.

Signed by me at Baltimore city, State of Maryland, this 24th day of July, 1899.
