LATCH.
SPECIFICATION forming part of Letters Patent No. 451,638, dated May 5, 1891.
Application filed January 31, 1891. Serial No. 379,768- (No model.)
To all whom it may concern.-
Be it known that I, FREDRICK J. LAU, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Latches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1t appertains to make and use the same, reference being had to the accompanying drawlngs, and to letters of reference marked Ehereon, which form a part of this specificaion.
This invention relates more especially to refrigerator-latches, and has for its object to secure certainty and ease of action and simplicity and economy in the cost of construction.
The invention consists in the improved latch and in the arrangement and combination of the several parts thereof, as herein shown and described, and finally pointed out in the claims.
Referring to the accompanying drawings, in which similar letters of reference indicate corresponding parts in each of the several figures where they occur, Figure 1 represents in front elevation a broken-off portion of a refrigerator-door and door-jamb and my improved latch, &c., attached thereto. Fig. 2 represents a back plan view of the latch; and Fig. 3, a similar view, the back plate being re moved and exposing the working parts of the latch in the case. Fig. 4 is a longitudinal transverse section taken through line :0 of Fig. 1, and Fig. 5 is a vertical transverse section through line y of Fig. 2. Figs. 6 and 7 represent plan and end views, respectively, of the catch-plate; and Figs. 8 and 9 represent side and rear elevations, respectively, of the catch-bolt and its operating-arm, &c.
In said drawings, A and B, Figs. 1 and 4, indicate, respectively, a broken-off portion of a refrigerator-door and the door-jamb.
0 indicates the latch-case, which has a front projection C.
d indicates a stationary knob, and e a bolt, which passes through the knob, case, and door, and is secured by a nut e inside of the door, thereby aiding to hold the parts together and to said door. The knob, however, may be through the back plate 0 of the case to engage with the catch-plate h when in a locked position, as indicated in Fig. 4. Said hookcatch is slightly tapering toward the end to facilitate its free entrance into the opening in the catch-plate h and to secure automatic action, as will be understood. Said catchbolt at its opposite end is provided with an operating-arm f, which projects through the outside of the case to within convenient reach from the knob, so that it may be grasped in connection therewith and the latch-bolt be 0perated by a slight pressure thereon to release the catch, as will be understood, the catch being thrown into locking engagement automatically by means of the incline on the hookcatch and a spring i, one end of which is seated against ahub j, projecting from the case-plate and the other against a cross-bar 7a in the skeleton portion or shank of the catch-bolt. The said operating-arm moves through a slot Z in the case-plate, as indicated in Figs 3 and 4.
The case is provided with hubs an and 4%, upon which the back plate rests. The knobshank or bolt 0 also passes through said hub m, and a screw 0 engages in a threaded socket in the hub n to hold said back plate in position, as indicated in Figs. 2 and 8.
The slotted catch-plate 72/, Figs. 1, 4., 6, and 7, is adapted to be secured upon the outside and inner edge of the 'door-jamb, suitable screw-holes 5 being provided therefor.
It will be noticed that the portion 0 of the case projects beyond the front edge of the door and overlaps the jamb, as indicated in Figs. 1 and 4., and that the latch-bolt is entirely concealed from view when the door is closed.
Having thus described myinvention, what I claim, and desire to secure by Letters Patent of the United States, is
l. The improved latch for refrigerators herein described and shown, consisting of the case 0 0, provided with the slot Z, hubs j, m, and n, a stationary non-rotating knob, a latchbolt provided with the hook-catch g, project- ICO ing through the back plate, the operatingconnected to said latch-bolt and projecting arin f, rigidly secured to said latch-bolt and outside of said case near said knob, said parts projecting through the front of the case, and being arranged to operate as described, and 15 a crossbar 70, and a spring seated against for the purposes set forth.
5 said hubj and cross-bar 7:, said parts being In testimony that I claim the foregoing I arranged and operating as described, and for have hereunto set my hand this 21st day of the purpose set forth. January, 1891.
