BOLT.

Application filed February 27, 1925. Serial No. 11,923.'

This invention relates to improvements in latchbolts, the construction disclosed being designed primarily for use in automobile doors.

It is an object of the invention to provide a novel latch bolt having all of the essential features of such bolts formed from a single piece of sheet material. It is a further object of the invention to so dispose the parts of the latchbolt that it can be conveniently stamped from sheet metal with an economy of both time and material.

Further objects will appear from the following description considered in connection with the drawings in which:

Fig. 1 is a plan View of a completed bolt embodying one form of our invention.

Fig. 2 is an edge view thereof.

Fig. 3 is a sectional view taken substantially on the line 3-3 of Fig. 1.

Fig. 4 is a sectional view taken substantially on the line 44 of Fig. 1.

Fig. 5 is a plan view of a modified form of our invention.

Fig. 6 is an edge View thereof.

Fig. 7 is a sectional view taken substantially on the line 7-7 of Fig. 5.

Fig. 8 is a sectional View taken substan tially on the line 88 of Fig. 5.

Referring particularly to Figs. 1 to 4, there is shown our improved latchbolt indicated as a whole at 10, and provided with a guiding head or body part 11, the extended end of the body part 11 terminating in the locking cam 12. The head 11 is formed without seams and comprises the vertical sides 13, the top plate 14 and the base or shank portion 15. The shank portion 10 of the latch is preferably formed of a single thickness of the sheet metal and terminates at its rear end in the upwardly extending flange 16. The flange 16 forms an operating element to be engaged by the pivoted handle 17, for example as shown in Fig. 1. The handle 17 may be considered the usual inside operating handle for the door latch. One of the side members 13 forming the head of the latchbolt has projecting therefrom at right angles to the bod of the latch a second operating or contro ling arm 18. The arm 18 is preferably formed as a continuation of the side members 13 and is bent upwardly with respect to the shank or base plate 10 along with the side member 13 and after being out along the bent edge of the said side member and shank the arm 18 is stamped out into the position shown. The arm 18 is adapted to be engaged by the operating cam 20 which may be moved by the usual outside door handle on the automobile door.

It will be seen that the latch construction as herein set forth may be formed from a single sheet of metal cut and stamped or drawn into the shape described at a great saving of time and material. The hollow reinforced head construction 11 is sufliciently durable to withstand the wear to which it is subjected and the arrangement of the operating flange and arm provides the desired operating elements on the latchbolt.

The form of invention shown in Figs. 5 to 8 is substantially the same as in the first four figures except that in the formation of the head the top or abutting plate 14' is drawn downwardly onto the vertical side members 13 of the head of the latchbolt, the plate 14 constituting originally an extended portion of the shank 10 of the latchbolt. This method of forming the head 11 leaves the seam 22 between the top plate 14: and the side members 13 as indicated at 22 in Fig. 6 and is in this respect different from the seamless head as seen in Fig. 2. The other element of this latchbolt such as the operating flange 16 and the operating arm 18 are substantially identical and are constructed in the same manner as the corresponding parts shown in Figs. 1 to 4.

Referring particularly to the method of producing the latch element disclosed in Figs. 5 to 8 it will be seen that the first step in the process is the cutting of the metal plank into the proper shape so that the side members 13 may be bent upwardly to form the reinforcing edges against which the extended end 14 of the head is pressed. The portion of one of the side members 13 in the rear of the head portion 11 is cut from the shank portion 10 so that it may be bent to project outwardly as seen in Figs. 5 and 8 and the latch is then complete and ready to be installed. While we have shown and described certain specific constructions these are to be considered as illustrative merely, the scope of our invention being set forth in the appended claims.

We claim as our invention 1. A latch bolt formed from a single piece WINDOW REGULATOR COR- of sheet metal and comprising a shank mem guiding head including a hollow body part her, a guiding head including a locking cam and a locking cam, one of the sides of said on one end of said shaft member, a controlbody part being extended outwardly to form ling flange adjacentthe other end of said an operating arm.
