FREDERICK A. POTTER, OF NElV YORK, N. Y.

DOOR-SECURER.

SPECIFICATION forming part of Letters Patent No. 552,394, dated December 31 1895.

Application filed July 12, 1895. Serial No. 555,740. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK A. POTTER, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Door-Securers, of which the following is a specification.

My invention relates to an improvement in (loor-sccurers, the object of the same being to provide a device of this kind which shall be cheap to manufacture, simple but durablein construction, and of such small size or compass that it can be conveniently carried in the pocket, and which at the same time may be fitted to any and all doors of ordinary construction.

\Vith these ends in view my invention consists of a door-securer made of two plates shaped and bent as shown, one sliding upon the other, and having openings therein arranged in a certain and new way, whereby by the insertion of a wedge-shaped key or fastener into two registering openings the sliding plate may be removed longitudinally upon the other until it fits tightly and snugly against the door and be immovably held in such adjustment.

My invention further consists in certain novel features of construction and combination of parts, as will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of my improved door-securer. Fig. 2 is a face view thereof, the key being shown in section. Fig. 3 is a sectional view thereof, taken on the line 3 3 of Fig. 2. Fig. 4 is a sectional View taken on the line 4 4t of Fig. 2. Fig. 5is aseetional view taken on the line 5 5 of Fig. 6. Fig. 6 is arear View thereof, showing the attachment; of the key when the device is not in use.

Referring to the drawings, A B represent two plates, the forward end of the plate A being bent at right angles to its length, as shown at a, for insertion between the edge of the door jamb and frame, as is usual in this class or kind of door-securers.

On the rear end of the plate A is secured the metal plate I), the edges of which latter overlap the sides or edges of the metal plate A, as shown in Fig. 4, the said plate I) having the lugs or projections 0 formed on or secured thereto. Between the metal plate A and the plate 1) slides the plate 13, the forward end of the latter being bent at right angles to its length, as shown at d, for providing the necessary shoulder or bearing surface to fit against the face of the door, a strip or plate of metal 0 being secured to said plate I) and having its ends bent over to encircle the plate A for assisting in preventing said plates A B from becoming detached and for assisting the plate I) as a guide for the longitudinal movement of the sliding plate B-upon the plate A. The rear end of the plate B is also bent at right angles to its length, as shown at f, the said bent portion being provided with an elongated slot or opening g, the purpose of which will be hereinafter described.

One of the main features of this invention lies in the formation and arrangement of the several series of openings in the two plates A B, several horizontal rows of which are formed in the plate 13, as shown at h, these openings being elongated and those in the same horizontal row separated by a portion of the metal 2', which is narrow as compared with the length of the opening itself. These openings are so arranged that those in one horizontal row will be slightly in advance of those in the next adjacent row, preferably ascending in a line toward the forward end of the plate B and descending toward the rear of the plate B.

In the plate I) are formed the openings k, of the same, or approximately the same, dimensions as the openings h, and separated by the same width of metal as are the several horizontal rows of openings h. The openings 7c are formed opposite to corresponding elongated openings Z- formed in the plate A, said openings Z being preferably arranged in advance of each other, so that they will ascend or descend in a direction opposite to those formed in the plate B. By this construction and arrangement of the openings it will be seen that when the plate B is moved upon the plate A until the openings k 6 come opposite the openings h, they will so register that there will be no passage-ways extending through the several plates of the same size, or, in other words, there will be no duplicates, the hole or passage-way in one row be-.

ing larger or smaller than that in the next adjacent row. In practice, the bent end of the plate A is inserted between the edge of the door and door-frame, and the plate B moved horizontally upon said plate A until the bearing end'cl fits tightly against the face of the door. The wedge-shaped key D is then passed through one of the passage-ways formed by the registering openings 7L 7.: l, and forced therethrough until the said plate B fits very tightly against said door, said key holding the plates A B in this adjustment, it being understood, of course, that the bent end of the plate A is inserted in the hole formed in the door-frame for the reception of the locking bolt or catch,

From the above description it will be understood that when the device is secured to a door the wedge-shaped key, by reason of its shape, will tend to force the plate 13 tightly against the door when passed in and through the openings in the several plates. The further the key is forced the more tightly is the plate 13 pressed against the door, and hence there will be absolutely no movement allowed to the door after being locked or fastened by the securer.

\Vhile I have described and prefer to use several rows of elongated openings in the several plates, I would have it understood that I do not limit my claim thereto, as one opening may be formed in each plate sufliciently long and the wedge-shaped key made sufliciently wide to accomplish almost the same effect.

hen not in use and to prevent the wedgeshaped key from becoming lost or misplaced, it is passed through the slotor opening g formed in the rear end of the plate B, one end of the key being also bent or turned at right angles to prevent it from passing entirely through said opening. In passing the wedge or key through said opening 9 the forward end thereof is passed between the plate A and the lugs or projections 0 formed on the plate 1), thus securely binding or locking said wedge or key to the sccurer and preventing its accidental displacement.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A door 'securer, consisting of two flat plates sliding one upon the other and having their ends bent as shown, each of said plates being provided with several horizontal rows of elongated openings out of vertical alignment with each other adapted when said plates are moved to register with each other, in combination with a wedge shaped key adapted to pass through the openings in said plates and. move one of the latter horizontally, substan tially as shown and described.

2. A door securer consisting of the plates A, B, Z), said former plate being provided with several horizontal rows of elongated openings, those in one row being slightly in advance of those in adjacent row, the said plates 13, I) be ing also provided with oppositely arranged elongated openings, also arranged slightly in advance of each other, but ascending in a direction different to those in said plate A, and a wedge shaped key adapted to pass through said openings, and slide the plate 13 upon the plate A, substantially as described.

3. A door securer consisting of the plates A, B, b, constructed and arranged substantially as described, the said plate 13 having its rear end bent and provided with an opening g, the said plate I) being provided with the lugs or projections c, and a wedge shaped key adapted when the device is not in use, to pass through said opening g and under the lugs c substantially as described.

Signed at New York, in the county of New York and State of New York, this 10th day of June, A. D. 1895.
