Description
' UNITED STATES PATENT CFFIG THE RUSSELL & ERWIN MANUFACTURING COMPANY, OF SAME PLACE.
SH EETeM ETAL LOCK-GAS E.
srnorrrcmrron Application filed July 18, 1889.
To all whom it may concern.-
Be it known that I, HENRY E. RUssELL, Jr., a citizen 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 Sheet-Metal Lock- Cases, of which the following is aspecification.
My invention relates to improvements in sheet-metal lock-cases; and the objects of my improvement are to cheapen the construction and improve the efficiency of the article with particular reference to fastening the lockplates together.
In the accompanying drawings, Figure 1 is a side view of my lock-case. Fig. 2 is a sectional view of the same on line-o9 a: of Fig. 1, and Fig. 3 is a like view of a modification of the same.
My improvement is applicable to sheetmetal lock-cases and latch-cases in general, and relates to the construction of those portions of the lock-plate and cap-plate which receive the fastening-screw.
Examples of sheet-metal lock-cases to which my improvement is applicable may be seen in the patents to C. M. Burgess, Nos. 396,915 and 396,916, January 29,1889, and Nos. 399,239
7 and 399,240, March 12, 1889.
In those portions of the lock-plate A and cap-plate B which are designed to receive the fasteningscrew 4, by which said plates are held together, 1 form a screw-seat 5 by swaging or striking up the metal from the body of the plates in the form of a hollow boss, the depression being on the outside of the plates and the projection on the inner side. I prefer to make the projection about equal to onehalf the thickness of the case, and form a reversely-swaged central portion 6, as shown in Figs. 1 and 2, to bring the screw-seats a little distance apart, while the principal bosses contact with each other and hold the lock-plates forming part of Letters Patent No. 412,419, dated October a, 1889.
SerialNo. 317,881. (No model.)
' a given distance. In Fig. 3 the hollowbosses are made to project inwardly alittle less than half the thickness of the case, and the reversely-swaged central portion is omitted.
In both forms one part is perforated with ahole large enough to receive the body of the screw, and the other part has a smaller threaded hole to receive the threaded portion of the screw.
By my improvement I arrange for the fastening-screw at practically no expense, as the screw-seats may be formed simultaneously with striking up the other parts of the case. I also in the preferred construction dispense with the separately-formed stud or post to keep the lock-plates the proper distance apart.
I bring the screw-seats so near each other that a short screw may be used, and the screw can be much more conveniently inserted than it can in a lock-case having widely separated seats. The end of the screw may extend through the screw-seat and not project beyond the lock-plates, thereby making it especially adapted for sheet metal having no great thickness.
I claim as my invention- 1. The herein-described sheet-metal lockcase, having screw-seats swaged or struck up in its plates in the form of perforated hollow bosses projecting inwardly, substantially as described, and for the purpose specified.
2. The herein-described sheet-metal lockcase, having screw-seats swaged or struck up in its plates in the form of perforated hollow bosses projecting inwardly about half the thickness of the case, and having also the reversely-swaged central portion, substantially as described, and for the purpose specified.
