BLIND HINGE AND LOCK.

Specification of Letters Patent.

Patented Nov. 14, 1905.

T0 (0% whom, it may concern: Be it known that I, REUBEN W. PERRY, a citizen of the United States, residing at Lynn, county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Blind Hinges and Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

It is frequently desirable to be able to fasten a shutter or blind so that it cannot be moved from its position or rattled or shaken by the wind. A device for this purpose should be very strong, so that it will be able to withstand considerable rough usage, it should be certain in its operation and easy to operate, because it is sometimes necessary that the shutters or blinds be hurriedly closed, as in case of fire or a suddenly-approaching storm,and it should be cheap, so that it will not add materially to the expense of the shutter hinges or hangers. My invention does away entirely with the fasteners or catches heretofore in use, thus saving their cost and the labor of putting them up.

My invention also does away completely with the trouble and annoyance sometimes experienced from sparrows or other birds roosting on the fasteners or catches.

The invention is adapted for use on the blinds of dwelling-houses and on fire-shutters, which must sometimes be closed hurriedly; but it is obvious that it may also be used in connection with hinges of all kindsas, for instance, those used on doors and gates.

My invention may also be embodied in a modified form which enables me to apply it to the shutter or blind hangers already in use.

The invention will be fully understood from the following description, in which reference is made to the accompanying drawings, and the novel features thereof are pointed out and clearly defined in the claims at the end of this specification.

In the drawings, Figure 1 is a view in perspective of a portion of a casing and a shutter hung with a lock-hinge embodying my invention. Figs. 2 and 3 are details of the parts.

Fig. 4 shows a modified form suitable for ap plioation to an old hinge or hanger.

Referring to the drawings, the casing is indicated by A and the shutter by B. A lower hinge member 0 is driven into the casing in the proper place and is provided with the usual pintle 1, upon which the upper or movable hinge member D swings. The lower hinge member is provided with one or more braces 2, which help to carry the weight and keep the hinge member C from sagging or getting out of true. The parts of the hinge member C which have thus far been described may be of any convenient shape and form nopart of my invention. On the under side and front of the fixed member 0 and below the pintle 1 I provide a series of notches 8 of considerable depth and slightly wedge-shaped in form.

The second or movable member D is attached to the shutter in the usual way, as by the screws 3, and is provided at the side with a tubular portion 4 for engagement with the pintle l of the lower or fixed hinge member 0 and at the bottom with a second tubular portion 5 at right angles with the tubular portion 4 and offset, as shown in Fig. 2. The top of this tubular portion 5 is on a level with the tops of the notches 8 in the fixed hinge member C. This hinge member D may be made from some suitable sheet metal bent into the desired shape, as shown in the drawings, or, if preferred, may be cast. The shutter is cut away slightly to receive this lower tubular portion 5, as shown in Fig. 1. In this tubular portion 5 I place the bent locking-lever E, which is provided with a handle 6 and a point or finger 7, Which engages with one of the notches 8 in the fixed hinge member C. The looking-lever E turns about the portion within the tubular portion of the hinge member D as a pivot, and thus moves the point 7 into or out of engagement with the notch 8 in the fixed hinge member (J. The handle 6 is made of sufficient weight so that the locking-lever is normally in the position shown in Fig. 1, with its point in engagement with one of the notches in the fixed. hinge member C. The notches, as previously stated, are made slightly wedge-shaped, so that the jarring of shutter tends to cause the point of the locking-lever to work farther up into the notch and hold the shutter more firmly, thus preventing all rattling.

When it is desired to move the blind from one position to another, the locking-lever E is lifted by its handle to the position shown in dotted lines in Fig. 1, thus disengaging the finger 7 from whichever notch 8 it is resting in. The blind is then swung to the desired I the shutter.

When it is desired to use my inventionin connection with the ordinary form of hanger, as shown in Fig. 4, I provide a washer 10, having a hole suitable for the reception of the pintle 16 of the hanger and having depending projections 11, forming notches 12, similar to those described in connection with Fig. 1. One of these notches 12 passes down over the arm 15 of the hanger, and this prevents the rotation of the washer under the pressure of the blind. The point 7 of the locking-lever engages the notches in the same Way as heretofore described.

What I claim is- 1. A lock-hinge comprising a fixed hinge member provided with notches upon its under side, a movable hinge member, a rock-shaft pivoted to the said movable hinge member and provided with a finger extending below the said fixed hinged member and engaging one of the said notches therein.
