LA'roninG DEVICE.

Application filed, May 11,

My invention relates; to latches and especially'to latches for use on windows and: similar structures; isradapted particularly for use where it is desiredto: latch the structures in fixed rela-tion'toeaclr other so as to prevent movement of same from tl e oppositeside, as in the instance of windows, While at the same time preventing any one from disengaging the latch or tampering with it.

In the drawings Fig. 1 shows my latch ap plied to the lower sash and the easement of a window;

Fig. 2 is a cross section through the latch in Fig. 1;

Fig. 3 is a perspective view or" one torm of my latch;

Fig. 4 is a cross section of my latch ap= plied to the upper and lower sash;

Fig. 5 is a front view' of Fig. 4:.

In the drawings in which like characters refer to like parts A is a window sash, B is the casement. In one form of my invention I fixedly attach to the sash'A by screws I) the latch plate D, and to the casement I fixedly attach the plate C by screws C. The plates C and D are provided along their longitudinal edge with a plurality of separate integral portions, F on the plate C, and E on plate I), turned or bent so as to form passages F in the plate C and passages E in the plate D. These portions E and F are preferably spaced and arranged so that when the passages E F are brought into register the portions E and F alternate.

I provide a readily removable pin or locking member G which when the passages E, F are in register is passed through the passages thereby securely latching them in register and locking the adjacent members of a structure together against movement independently of each other.

In Figs. 4 and 5, I show one form of my improved latch adapted to latch adjacent window sashes together in a number of different positions so that the window may be entirely closed or partially opened. In this form the plate 0 is attached to-the top of the sash A. In the sash I, I arrange slots or holes J. The plate D is provided with an extension or projectionsK arranged to be inserted in the slots or holes J. The'extension orprojections K are preferably arranged on the plate so as toextend from the 1923: sen-a1 No. 8383246.

edge opposite the edge having the enlarged portion E so-that when the extension or projections K are inserted into the: slot or: holes .1 the passage E the enlarged portion E' may be brought into= register with, the passage F in the enlarged pent-ion F on, the plate C so. as tov permit, the pin or meme ber G to be inserted in the passages to latch the plates together. In this way, dependent uponthe position of the slot or holes-J into which the extension or projections K are placed, the window may be securely latched either closed or partially opened, and the sashes so latched together to permit, if desired, movement of same as a single unit. In Fig. 5, I show in the sash a, series of openings or holes N into which the end of pin G may be inserted to latch the windows in any desired position. The number of difler'ent positions being dependent upon the number of holes N. 7

Claims 1. In combination with a plurality of separate structures comprising a plurality of window sashes and a frame therefor, said structures slidable relative to one another, a plate directly attached to one of said structures, a second plate attached to another of said structures, said plates being mounted in different planes and provided with passages adapted to be brought into register, and loosely fitted in and means passing through said passages for connecting said plates together whereby the respective structures to which said plates are attached will be held against substantial movement independently of each other. i I

2. In combination with separate structures one of which is movable independently of the other, a latch having a plurality of separate members provided withpassages adapt ed to be brought into register, one of said members being fixedly secured to one of said structures, the other member being de tachably connected to the other structure at any one of a'plurality of positions, and means passing through said passages to hold the separate structures to which the members are operatively attached in fixed position in relation to each other.

3. In combination with. a plurality ofseparately movable structures and a frame therefor, a latch having a plurality of separate members provided with. passages adapted to be brought into register, one of said members being fixedly secured to one of said structures, the other member being detachably connected to the otherstructure at any one of a plurality of positions, and means passing through said passages to con nect and hold the separate structures to Which the members are opcratively attached in fixed position in relation to each other, said means adapted to lock the connected structures to said frame in any one of a plurality of positions. Y

4. In combination With a plurality of separately movable structures and a frame there for, means, including a plurality of separate plates having interfitting parts adapted to be detachably connected together, for latching said structures together so as to be movarately movable structures and a frame therefor, a plurality of separate plates directly attached to said separate structures, and

means for detachably connecting said plates together and thereby connecting said structures, such connecting means adapted to latch such connected structures to .said frame in any one of a plurality of positions.

In testimony whereof, I have signed my name to this specification.

HARRY o. INNES.
