CHARLES M. BURGESS, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE RUSSELL d: ERVIN MANUFACTURING COMPANY, OF SAME PLACE.
To all whom it may SHEET-METAL LOCK-CASE.
SPECIFICATION forming part of Letters Patent No. 412,365, dated October 8, 1889.
Application filed July 18, 1889. Serial No. 317,876. (No model.)
Be it known that I, CHARLEs M. BUEGEss, 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 Sheetnletal Lock- Cases, of which the following is a specification. My invention relates to improvements in sheet-metal lock and latch cases, and the main objects of my improvement are to lessen the cost of production and to produce a case that is specially adapted for a Janus-faced lock.
In the accompanyin a side elevation of my lock-case.
g drawings, Figure is Fig. 2 is a sectional viewr of the same on line fc o; of Fig.
l. Fig. 3 is a rear ele is a corner elevation bottom edges. Fig. 5
vation thereof. Fig. 4C showing the front and is a plan view, on areduced scale, of the blank for one of the plates; and Fig. 6 is a like view of the blank for the companion plate.
The plate A, which I may term the lockplate,7 I form from a rectangular blank having notches or recesses 7 '7 at two corners and a central notch 8 at its rear edge.
It is also provided with the ordinary holes, the., for the various parts ot the lock and latch, which may be chau ged according to the particular lock to be produced.
The companion plate B, which with notches at each corner, two of them 9 9 being of the saine Width as the notches 7 7 in the plate A, and wider. The rear edge projection plate A.
up on two sides subst lines indicated in Figs the other notches .l0 10 being is also provided With a 11 for entering the notch S in The blanks for these plates are bent antially on the broken .5 and 6 to form flanges,
the blank being preferably swaged or struck up to give the broad sides of the case an ornamental effect and to stiien the same, as
shown. The flanges 1 2 12 on the plate Aare at the front and rear edges of the case, While the flanges 13 13 on the plate B are at the top and bottom edges. T
he notches 7 7 and 9 9 are about half the Width of each of said anges, while the notches 10 width as said flanges.
10 are about the same The two parts of the case are then put together, with the Ilan ges of one part entering the spaces between the 5o lian ges of the other parts, so as to form a complete box or case. The ends of the rear one of the flanges 12 of plate A enter and lill the notches 10 10 of the plateB,Wliile thenotches 7 7 and 9 9 and ends of the flanges 13 13 of' 55 plate B and the front flange 12 of the plate A fit into each other and forni rabbeted front corners, all as shown in Fig. 4. While I prefer to rabbet or notch the llanges at the front and rear edges in the particular manner shown 6o it is evident that all of the corners may be rabbeted in the manner shown for the front edge of the case or for the rear edge. By my improvements the ease is neatly and cheaply formed of only two pieces of sheet metal, thereby avoiding riveting and several other operations usually required in the production of sheetfmetal loch-cases. At the same time my lock-case is substantially alike on both sides, and is therefore specially 7o adapted'for a Janus-faced lock.
I claim as my invention- 1. The l1ei'ein.described sheet-metal lockcase, consisting of two plates, each provided with flanges on two opposite side edges and fitted together, with the said flanges of each plate covering the edge of the case at the unflanged edges of the companion plate, substantially as described, and for the purpose specilied. So
2. The herein-described sheet-metal lockcase, consistingof two plates, each provided with flanges on two opposite side edges and litted together, with the said flanges of each plate covering the edge of the case at the un- S 5 flanged edges of the companion plate, the corners of the case being notched at the ends of said flanges, with the endsofwtheinterlocking lianges received in said notches and"for1ning rabbet-s, substantially as described, and or 9o the purpose specified. l
