Specification of Letters Patent.
LATCH.
Patented Jan. 4,1916.
Application filed. June 18, 1915.' Serial No. 34,928.
To all whom it'mayconcern: [Be itknown-that I, JOHN H. LAWRENCE, a citizen of-theUnited States, residing at Sterling, in tliecounty of Whiteside and State of Illinois, liaveinvented certain new and useful Improvements in Latches, of which the following is a specification;
- My invention pertains to latches, of that class which are employed in securing barndoors, gates, and similar swinging objects in closed'position.
The device is designed to be formed almost entirely of sheet-metal, resulting in a simple and'durable construction and arrangement of the parts, and a-minimum cost of production. My invention also contains novel means whereby the same may be readily adjusted to closures of varying thicknesses, when the parts thereof are' being secured in position; also means for locking the movable parts of thevlatchjfrom movement, when the door or gate is closed. ,In' thedrawings': Figure 1 is a plan view .of the :inner face of the latch, in position with the latch extended. Fig. 2 is a 'similar view, with the latch withdrawn." Fig. 315
a vertical longitudinal section vertically of the latch and" companion handle'therefor. Fig.4 is anend view of the latch. Fig. 5
isa'a plan-yiewof ablank from which'the plate "61is formed. 'Fig. dis a plan view'of the'handle-plate 7, as the same appears be-. fore the handle is attached thereto.
-'-=1 represents a; casing, providedwith flanges 2,having openings 3 whereby such casing canbe securedin place by screws or otherfastening devices. The casing 1 is centrallyprovided with a circular opening 4, a ortion of the casing surrounding'such opening beingpressed outwardly to form a rim 5. I
'6 is a plateof a modified Maltese cross pattern, which is positioned -'on' the inner face of the casing 1,with its ends projecting into engagement with the rim 5.-" On thejoutside oftlie-casing is-a handle-plate 7, having a central depressed portion" 8, projecting inwardly into-the opening 4-of the casing, and in contact with the-plate 6, to which it'is attached by means of ears 9 on the plate 6 projecting'- outwardly thr'ough' perfora- 'tions 1Q in the-plate7, andvbent downwardly thereon'z I provided with ;-opp'ositely inwardly at approximately which are bent inwardly into engagement with the ends of aliandle 13 to secure said handle to such plate. By turning the handle the plate 6 is'given a partial rotation, for the purpose hereinafter set forth. By reason of the plates 6 and 7 embracing the casing at the edge ofthe opening 4: very snugly there is no looseness of the handle, such as would permit a lateral rocking thereof.
Slidable within the casing is a latch, comprising a bolt member 14 at one end thereof, and a housing 15 at the opposite end, such parts being united by plates 16, which are bent outwardly to form a pair of loops 17, adapted tobe engaged by projections 18 on the plate 6. The plates'lti are also bent inwardlyto form a pair of recesses 19, which accommodate the projections 18 when the plate 6 isturned', as shown in Fig. 2, or when thrown in the opposite direction. The bolt 14, housing 15, and plates 16 are preferably formed from one sheet of .metal, stamped in the'proper shape, and then bent to form the several parts. The plate 6 is also preferably formed from one piece of metal, as shownin F ig. 5, two of the ends of the plate 'beingprojected into fianges20 with which the'parts 18 are integral, the flanges 20 being first'bent upwardly at a right angle to the plate 6, and then the projections 18 bent a right angle to the parts 20.
Within the housing 15 is a coiled spring 21, one end of which bears against the end 22 ofthe housing and the other end against a projection 23 at the end of the casing. By this means the bolt 14 is held normally in extended or locking position, and returned thereto after having been withdrawn. It will be evident that by turning the handle 13 in either direction one or other ofthe projections 18'will engage the adjacent loop 11 to'move the bolt inwardly,-as shown in Fig. 2.; The'ends of the" loops are preferablyrounded, as shown, whereby the parts 18 have a partial rocking action thereon, reducing the friction ofsuch parts. The outer end of the housing 15 is on theoutside of the casing 1",'-and is projected upwardly into a tongue 24'provided with an opening 25, which is normally in register with a similar opening 26 inone end of the handle 13'.
or similar fastening device, such locking preventing a side movement of the handle to turn the plate 6 or an outwai'd movement of the housing 15, resulting in a double locking of such parts. The belt H passes through an opening in one end of the casing, a part of the casing being partially cut away to form such opening, and bent inwardly to provide a support or guide 28 for the bolt, so as to prevent displacement thereof on its inner movement.
The casing 1 can be formed of one sheet of metal, pressed into proper shape. The handle plate and appurtenant parts can also be formed from one piece of metal, as indicated in Fig. 6, and the plate 35 can be simil" rly produced, The handles 13 and 36 are also con s tjructe of "thin metal, bent into proper form, There are therefore no parts about the device tvhic h call for cast'ngs, or the labor that attends the making an finishin of suclrheavicr parts.
