SPECIFICATION forming part of Letters Patent No. 321,775, dated July 7, 188

Application filed September 5, 1884. (No model To all whom it may concern.-

Be it known that I, FRANK R. W001)- WARD, a citizen of the United States and arcsident of Hill, in the county of Merrimae and State of New Hampshire, have invented certain new and useful Improvements in Door-Securers; and I do hereby declare that the following is a full. clear,.and exact de scription of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of one form of my improved door-securer. Fig. 2 is a perspective view showing the same applied to a'door in position for operation. Fig. 3 is a longitudinal sectional view. Fig. 4 is a transverse sectional view taken on the line or a: in Fig. 3. Fig. 5'is a side view showing the slide of the device reversed and the device in position for. being carried in the pocket. Fig. 6 is a perspective view illustrating a modification in the construction of my improved door-securer. Fig. 7 is a transverse sectional view of the latter.

The same letters refer to the same parts in all the figures.

This invent-ion relates to door-sccurers; and it has for its object to provide a device which shall be simple in construction, durable, convenient in operation, and easily carried in'the pocket, so as to be available for the use of travelers and others.

WVith these ends in view the invention consists in the improved construction and arrangement of parts, which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A designates a flat sleeve having a bulging portion which forms a casing, B, at one end. The said casing has a transverse opening, 0, in

which is fitted a slide, D, which may be retained in any position to which it may be adjusted by the pressure against it of a small spring, E, suitably located above it in the casing B. The under side of the slide is provided with a recess, F, whereby it is adapted to engage the notches G G, formed in the sides of a slide, H, fitted to move longitudinally in the sleeve A, and provided at one end with a laterally-projecting spur, I.

It will be observed that the notches G in one side of the slide H alternate with those formed in the other side, so that it is necessary to move the said slide only a very small space for the purpose of causing the latchslide D to engage one of the said notches, thus enabling the device in practice to be very nicely adjusted.

The operation of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed.

To adjust the device, it is only necessary to move the sleeve A back upon the slide H, insert the spur of the latter into the jamb, and

close the door, thus preventing the withdrawal of slide H. The sleeve is then moved up closely against the door, where it is held or retained by the action of the latch D, engaging one of the notches in the slide, thus fastening the door securely.

To remove the device the operation is simply reversed. The slide H may then be reversed in the sleeve, as shown in Fig. 5 of the drawings, and drawn back until the spur I rests against the enlarged portion B of the sleeve, in which position the slide may be secured by the latch D engaging a suitablylocated notch in the side of the slide. The device may thus be carried without danger of mutilatin g the pocket.

In Figs. 6 and 7 I have shown a modification in the construction of the device in which the latch D is adapted to engage notches in one side of the slide H only, it being forced into contact with the said notches by a spring, L, bearing against one of its ends, while the other end forms a projecting handle, M, by means of which it may be conveniently manipulated. The operation of this device is identical with that already described.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States In a door-securer, the combination of a sleeve having an enlarged portion forming a casing at one end, a latch arranged to slide In testimony that I claim the foregoing as transversely in the said casing, a spring army own I have hereunto allixed my signature ranged to bear against and retain the said in pvesence of two witnesses.
