DAVID 1). GOOD, 0]? PHILADELPHIA, PENNSYLVANIA.

PORTABLE DOOR AND WINDOW' LOCK.

Application filed February 10, 1914. Serial-N0. 817.909.

To all whom it may concern Be it known that I,D.ivn D. G001), a citizen of the United States, residing at 6203 Jefferson street, in the city of Philadelphia and State of Pennsylvania, have invented certain Improvements in Portable Door and Window Locks, of which the fol lowing is a specification.

This invention relates to improvements in devices for the fastening of doors and windows by the means of a portable lock to be carried by the traveler and others, by which a door having an ordinary lock may be fastened from the inside, preventing its being opened by a pass or skeleton key. The said portable lock being attached or detached without marring the woodwork. It is also adapted to the locking of windows.

My invention is fully described and shown by the accompanying drawing and specification.

Throughout the accompanying drawing, illustrating my invention, similar numbers refer to similar parts.

Figure 1 is a perspective view of the portable door and window lock showing the plate and wedge attached by chain.

Fig. 2 is a perspective view of the lock from the reverse side, in its relative position to the door jamb when engaged by the keeper of the permanent or fixed lock of the door.

Fig. 3 is a vertical sectional view of the lower rail of an upper Window sash and the upper rail of the lower sash with the portable lock in place.

Fig. 1 shows a thin steel plate so cut and stamped that the rectilinear member 9 remains in its original plane. The triangular parts 2 and 3 stand perpendicular to this plane an edge of each forming a right angle with the longer member or part 1 of the plate. A rectilinear opening 10 is out therein, a rectilinear member 21 is bent outward on one of its longer sides at an acute angle to the part 1.

The removal of the portion 10 and bending outward of the member 21 leaves a rectilinear opening of length a trifle shorter than the greatest width of the wedge 12 and wider than the thickness of the said wedge. Rectilinear portions are cut from the plate to form the openings 5 and 6 through which the smaller end of the wedge 12 may be inserted. All of the said openings being at different distances from the end of the plate.

The corners 7 and 8 of the plate 1 are bent outward at right angles to the plane of the plate.

The wedge 12 is of thicker material than the plate and has one concave and one convex edge 11 and 20. The plate and wedge are attached to each other by the chain 19 at 13 and 13.

In Fig. 2 the tangs 2 and 3 are shown inserted in and engaged by the keeper which is fixed to the door jamb and the wedge 12 in the slot 10, the wedge being held at an acute angle with the plate 1, by the member 12.

In Fig. 3, 15 is a section of lower rail of upper sash of a window. 16 is the upper rail of the lower sash. The plate 1 is laced between the two rails, the corner ugs 7 and 8 engaged under the rail 15, the wedge 12 placed above the rail 16 and through the opening 6 in plate 1.

The use and advantage of the above describeddevice is as follows. The average mortise door lock being easily opened by skeleton or pass keys, I have provided in my invention a small compact device consisting of a plate having two tangs or lugs which are insertible in the latch keeper on the door jamb. The door then being closed holds the plate in its proper position and prevents the said tangs from being disengaged.

The curved wedge is then inserted clownward in the long slot until its edge bears against both door and jamb holding the door securely closed.

The angular member adjacent to the slot holds the wedge in a semiupright position preventing its falling or being shaken from the plate.

The convex and concave edges of the wedge serve to adapt it to various thicknesses of doors and designs of molding on the door jamb.

For my invention to perform its function of a window lock the lower sash is raised sufficiently to allow the end of the plate having two corner lugs being slipped between the sash rails, the lugs outward and engaged under the upper sash. If the lower sash is then closed and the wedge inserted in one of the slots, it will prevent either sash being moved.

Having thus described my invention what I claim as novel and desire to secure by Letters Patent of the United States is:

The combination in a portable lock of a Specification of Letters Patent. Patented Oct, 14, 1919.

)late trian ular tan 's ada )ted for insertion in the door frame, a slot, a guide adjacent the slot forming an acute angle With the plate adapted to maintain an element, When it is inserted in the slot, in a stable position, and a flat Wedge, one of its edges concave and the other convex adapted to be inserted in the slot and when so inserted bears against the closed door and frame se- 10 curing the former in its closed position.

In testimony whereof I have hereunto signed my name at Philadelphia, in the county of Philadelphia and State of Pennsylvania, this 26 day of Dec., 1913 in the presence of the two subscribing Witnesses.
