WILLIAM FRANKLIN DAVIS, OF BOSTON, AND CHARLES ELBRIDGE BROAD, OF MILTON, MASSACHUSETTS.
Letters Patent No. 89,295, lated Apr/il, 27, 1869.
IMIPROVED DOOR-FASTENER.
The Schedule referred to 1n these Letters Patent and making part of the same.
To all whom it may concern Beit known that we,W1LLIAM FRANKLIN DAV-rs, of Boston, in the county of Suffolk, and CHARLES EL- BRIDGn BROAD, of Milton, in the county of Norfolk, State of Massachusetts, have invented an Improved Portable Door-Fastener; and we do herebydeelare that the following is a full and exact description thereof, reference being had to the accompanying drawings,
.making part of 'this specificationkdoor-fastener, for the use of travellers and others. It
is adapted to doors having any kind of latch or lock.
The instrument consists of four parts-the main piece, or body A, two shoulder-pieces, B C, and athumbnut, or screw, D.
The main piece, or body A, consists of a thin, flat metallic strip, of about the shape and size represented, having a solid catch, or hook, a, at one end, and one or more teeth, b, turned at about right angles to the body,
at the other end.`
This main piece is to be inserted between the swinging edge of the door and the door-janib, the catch a being designed to be used when there is a catch-mortise in the jamb, by inserting it into the said mortise in place of the lock-catch, and the tooth, or teeth b being used when no mortise is in the jamb to hold by, the said teeth being driven into theV jamb, by the act of closing the door.
After the fastener is inserted in place, either with the catch a or the teeth b, in the jamb, and the other end, ineither case, projecting directly into the room, when the door is then closed, it holds the fastener from being withdrawn or forced out.
When the main piece A of the fastener has been thus -inserted between the door and door-jamb, the shoulderpieces B C are to be brought close up, the one to the door-jamb and the other to the door, and then tightly clamped to the main piece by turning theV thumb-nut D; and, when thus applied, the instrument securely holds the door, so that it cannot be opened from the outside, except by such violence as will cause something to .give way.
The shoulder-pieces B C are reversible in position, so as to present their shoulders fg to either end of the main piece, as required.
In order to adapt the instrument to its proper and most efficient use, the pieces A B C have certain peculiarities of construction and capabilities of adjustconnect the shoulder-pieces B O thereto and to each other, and allow them to be adjusted nearer to or further from the catch ay or teeth b, to suit different thicknesses of doors. v'
The shoulder-piece B, which forms one piece with the screw e, as shown, or tovwhch the screw may be attached, has an oblong projection, d,- figs. 4 and 5, at the base of the screw, formed to t lengthwise in the slot c of the main piece A, for the purpose of keeping the shoulders from turning out of position, and to hold the screw from turning round when tightening up the thumb-nut D.v j The shoulder-piece C has alongitudinal slot, h, through which the screw e extends, so that the piece may be adjusted even with, -or different from the shoulder-piece B, to t when the door projects further than, or not so far as the jamb.
The body of this piece is made thicker at or toward its shoulder than at the other end, so that it will not slip from the position in which it is adjusted.
Across the contiguous surfaces of all the pieces, there are slight cross-grooves, or notches, as shown ati i, to prevent the shoulder-pieces from slipping on the main piece.
The thumb-screw and its nut may be of ordinary construction..
The screw might be separate from the shoulderpiece B, and pass through it, having a head to hold it from slipping through the same.
The projection d should not be so thick as to reach through the slot in the main piece A, so as not to in-
