FRANK W. MIX, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE COR- BIN CABINET LOCK COMPANY, OF SAME PLACE.
MORTlSE-LOCK.
SPECIFICATION forming part of Letters Patent No. 320,155, dated June 16, 1885.
Application filed March 12, 1895.
To all whom it may concern:
Be it known that I, FRANK W. MIX, 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 Mortise-Locks, of which the following is a specification.
My invention relates to improvements in that class of mortise-locks which have overhanging side walls or edges and are secured in place by being let into a routed cavity having overhanging side walls. In this class of locks thus secured the upper end of the lock is held in place mainly by the selvage. \Vhen 1 the wood in the drawer-rail or front shrinks so much that its upper edge is below the selvage,t-here is nothing but the cap to then hold the look within the mortise. Ordinarily the cap is secured by lugs at points so far from the selvage of the lock that when the drawer is locked and is then pulled in a direction to open it the cap will bend back and permit the drawer to be opened without first throwing the lock-bolt into its case. Even if the wood shrinks so as to let its upper edge not quite down to the underside of the selvage, apull upon the drawer will cause the selvage to cut its way out of the mortise and the same result will follow.
The object of my invention is to so connect the upper end of the cap with the lock-case that when the selvage does not properly hold the lock within the mortise it will be so held by the edge of the cap.
In the accompanying drawings, Figure 1 is aplan View of my lock. Fig. 2isarearelevation of the same. Fig. 3 is avertical section of the same, together with the drawer-front. and Fig. 4 is a horizontal section of the same on line 00 w of Fig. 3.
(No model.)
The general form of the lock-case is the same as in prior locks of this class.
A is the lock-plate, B the cap, and C the selvage. In this selvage I form two slots in the same plane as is the cap B when in place, 5 and on the upper edge of the cap I form two upwardly-projecting lugs, a a, Fig. 1, which are passed through the slots in the selvage and secured by heading down their ends. When the lock is seated in place within the dovetailed mortise or routed cavity in the drawerrail D, as shown in Figs. 3and 4, the edge of the cap will bear against the side walls of the routed cavity and assist in holding the lock in place. The edges of the cap in prior locks of this class also bear in like manner on the side walls of the routed cavity, but by forming the cap with lugs which take into the selvage, the upper end of the cap is firmly secured, so that it will not be pulled back when the drawer is pulled outward after the selvage fails to properly hold the lock in place by reason of shrinkage of the wood, and in such an event the drawer cannot be opened without first throwing the lock-bolt, because the cap thus secured to the selvage furnishes a firm and reliable hold of the lock-case upon the side walls of the routed cavity.
I claim as my invention- The hereindescribed lock-case, consisting of the lock-plate, the slotted selvage, and the cap, the latter having lugs upon its upper edge which take into the slots in the selvage, substantially as described, and for the purpose specified.
