CHARLES M. BURGESS AND HENRY G. VOIGHT, OF NEW BRITAIN, OONNECTL CUT, ASSIGNORS TO THE RUSSELL & ERWIN MANUFACTURING COMPANY,

OF SAME PLACE.

' STOP FOR LATCHES.

SPECIFIGATIQN forming part of Letters Patent No. 450,353, dated April 14, 1891.

Application filed January 30, 1891. Serial No. 379,653. (No model.)

To all whom it may concern/.-

Be it known that we, CHARLES M. BURGESS and HENRY Gr. VOIGHT, both citizens of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Stops for Latches, of which the following is a specification.

Our invention relates to improvements in stops for latches; and the objects of our improvement are simplicity of construction, convenience, and efticiency in operation.

In the accompanying drawings, Figure 1 is a front elevation of a sufficient portion of a latch to show the connection of our stop therewith, the front plate being removed and aportion of the face-plate being in section. Fig. 2 is a like view of a portion of the same with the hub locked in place by the stop; and Fig. 3 is a vertical section on line :1; x of Fig. 2, looking toward the face-plate.

A designates the latch-case; B, the faceplate; O, the latch; D, the latch-lever, and E the hub, having a stop-notch 4 on one side, all substantially as in ordinary latches of this class.

F designates a rotary stop-bolt having bearings in the face-plate and in any suitable support, as at 5, within'the latch-case, so that said bolt may be partially rotated, while it is at the same time permanently held against lateral movement. The inner end of the bolt is provided with a crank-arm 6, having a locking projection 7 at its outer end. The rotary stop F is provided with a squared neck, as at 8, which fits within shoulders or cheeks 9 9, Fig. 3, on the inner side of the face-plate. The stop-bolt is provided with a spring 10, which has a constant tendency to keep the squared neck within the shoulders 9 9, as shown. The outer end of the rotary stop-bolt F is to be provided with any suitable means for rotating it-as, for instance, it may be fitted for the application of a'driver by means of a slot or its equivalent. When the'crankarm is in a horizontal position, so as to throw its locking projection 7 to the front, as shown in Fig. 1, the projecting portion of the hub E, havingthe notch 4, will pass under said looking projection 7, and thereby leave the latchhub free to be operated in the usual manner. By pressing upon the outer end of the bolt against the force of the spring 10 to slip the stop-bolt endwise sufficiently to force the squared neck out from between the shoulders or checks 9 at the inside of the face-plate the stop-bolt F may be turned one-quarter of a revolution, so as to bring its crank-arm into a verticalposition with its locking projection 7 within the notch 4 of the hub. Upon releasing the endwise pressure on the bolt the spring 10 will force the squared neck in between the shoulders 9 9 and lock the stop-- bolt in that position, thereby firmly locking the hub.

We are aware of the latches shown in the applications of HenryE. Russell, Jr., Serial No. 370,851, filed November 10, 1890, and Thomas Lyons, Serial No. 379,681, filed January 30, 1891, and the same are hereby disclaimed.

We claim as our invention- 1. In a latch, the combination. of the hub having the notch 4, a rotary stop-bolt having a crank-arm 6 at its inner end, with a locking projection 7 on the outer end of said crankarm for engaging the notch in said hub, substantially as described, and for the purpose specified.

2. In a latch, the combination of the hub having a notch, the rotating stop-bolt with a locking projection for engaging said notch and the squared neck, shoulders or checks 9 9 for receiving said neck, and the spring 10 for holding said squared neck within said shoulders, substantially as described, and for the purpose specified.
