LOCK-STRIKE.

SPEGIEICATION forming part of Letters Patent No. 244,169, dated July 12, 1881.

Application tiled April 23, 1881.

To all whom it may concern: Y

Be it known that I, JOHN H. BARNES, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Lock-Strikes and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure l, a front View; Fig. 2, side View; Fig. 3, perspective view as applied to the doorjamb.

This invention relates to an improvementin strikes77 or keepers for that class of locks commonly called rimlocks-that is to say, locks which are screwed upon the outer surface of the door and the keeper in a corresponding position on the jamb. To properly secure this class of keepers to thejamb, a dan ge is made on the side next the door to extend inward onto the jamb,so that the screw may be inserted through this ilange into the jamb. This method of securing is very much better and stronger than the other common method ot' inserting screws through the keeper directly into the jamb, because in the lirst case the strain comes at right angles to the screws, and in the latter the strain is in the longitudinal line of the screws, hence tends to force the screws outward and loosen the strike.

In the usual construction of the tirst class of keepers, to which this invention particularly relates, it is very difficult and practicably impossible to cast this class of strikes without a core, because the ilange extends the whole length ofthe face of the strike and must have an opening through it to receive the bolt.

The object of this invention is to construct the strike with extensions onto the jamb without coring, and the invention consists in constructing the strike-case with a ilange at the top and bottom on the striking edge, extending therefrom at right angles to the face of (Model.)

thejamb to which it is to be applied, as more fully hereinafter described.

A represents the strike-case, ot' the usual form, according to the style of lock to which it is adapted. On the edge of the strike side of the case, at the top and bottom, a liange, B, extends at right angles to the plane of the strike, with a space, C, between the llanges sufficient for the entrance of the bolt or bolts. These flanges are pierced for the insertion ot' screws into the jamb, as shown in Fig. 3, l) representing the face of the jamb.

By making the anges at each end, and so that a space is left between them throughout their extent, the strike is as readily molded as when there is no extension onto the face of the `jamb, because, as the flanges B are readily drawn from the sand, they add but little or nothing to the cost of the strike, except the additional weight of metal.

In the case of lock and latch strikes which are of considerable length an intermediate flange `may extend from the strike of the same character as the flanges B.

I am aware that strikes or keepers for rimlocks have been constructed with a ilange extending therefrom onto the face ot' the jamb; but in such strikes the iiange extended the entire length of the keeper, with an opening through it into the keeper for the bolts to enter. Such construction I do not claim as my invention, which is an improvement on such construction.

The herein-described strike for locks and latches, consisting of the case A, with the ilanges B B extending at right angles to the plane ot' the strike, and leaving the space bctween them to enable it to be cast without a core, substantially as described.

JOHN H. BARNES.
