LEVER FOR .AUTOMOBZIL' I .i

levers for motor driven vehicles and the object of my improvementsin this construction as compared with the usual drop forging is to eliminate weight and to produce an article of manufacture which will be lighter in weight, which will require no subsequent finishing or trimming, which will take the enamel better, and which will cost less to manufacture.

Levers of this class were first made of 2c brass or malleable iron castings, 'but as the cost of casting, heat-treating, trimming, and finishing was excessive, a cheaper and better method was sought. The result was dropforged levers, but even these were relatively heavy, necessitated trimming and finishing before the surfaces were in a satisfactory condition for eilameling, and were still relatively' expensive to produce. To improve upon thelever still further, the invention embodied herein has for its object the elimination of the objectional features of the types of levers mentioned above; also to provide a lever that is lighter in weight, and which requires no subsequent finishing or trimming, takes the enamel better'and costs-less to produce.

A lever embodying my invention is illustrated in the accompanying drawings in which;

Fig. 1 is a gartly broken side elevation of a lever embo ing the present invention.

Fig. 2 is a front elevation of the same.

Fig. 3 is a section taken on the line A-A of Fig. 1.

4 is' an enlarged section taken on the line B- of Fig. 1.

Referring to the numbered parts of the i drawing in which like numerals refer to similar parts throughout the several views, the lever jl is formed out of a sheet metal blank which has previously been sheared out to the required shape by methods. well known in the art. The body of the lever 1 with the exception of the ends 2 and 3 is formed into .a U shaped section as is shown in Fig. 3. The end 2 consists of two extensions 16 and 17, forming a clevis or 3' aw, the extensions being bent back on themselves to furnish sufiicient bearing surface for the cross pin 4 and also for the purpose'of gaining additional strength. The end 3 is pressed into a nearly cylindrical shape as shown in enlarged section in Fig. 4 to form a handle and a guiding means for the spring 5 and pawl actuating button} 6. A. cylindrical sleeve 7, shown in Fig. 1 and in section in Fig. 4 is pressed over the end 3 to form a suitable hand grip and to reinforce the handle. The drop forged metal part 8, is fastenedto .the body of the lever 1 by means of two rivets as shown in Figs. 1 and 2 and serves as a means of pivotally connecting the lever to the anchorage 13, by means of the shaft 9, and is so formed as to provide sufiicient bearing surface on the said shaft. The spring 15 on the shaft 9 serves to prevent lateral motion ofthe lever and thus prevent its rattling against the anchorage 13. The pressed metal strap 10, fastened to the body of the lever 1 as shown in Figs. 1 and 2 serves as a guide for the ratchet 11. The pawl .12, commonly and pivotally connected to the body of the lever 1, along with the parts 8 and 10 by a rivet as shown, engages with the ratchet 11, and is actuated by the button 6, which is slidably retained in the handle 3. Pressure applied to the button 6 is transmitted thru the rod 1 1 to the pawl 12. The rod is bent to such a shape as to normally contact against the body of the lever 1, so as toreceive support therefrom, thus preventing rattling and also further bending of the rod on the application of downward pressure to the pawl actuating button a What I claim is r 1. A pressed metal lever substantially U shaped 1n cross section for the greater part of its length, and having an inte al fulcrum member disposed within sai section other .than at the ends. thereof; a pawl pivotally mounted on said lever; means for operating said pawl; and means for preventing said pawl operating means from rattling against said lever. I

2. A pressed metal lever substantially U shaped in cross section for part of its len h, having one end formed into a cylindrical are shape to receive a sleeve, a fulcrum member secured to said lever, a pawl, and means within said lever for operating said pawl.

3. A pressed metal lever in combination with an integral fulcrum. member; one end of the lever formed into a clevis or jaw, the other end of the lever formed into a nearly cylindrical shape; a cylindrical sleeve incasing one end of the lever; a pawl fulcrumed on the lever and means inside the lever for actuating the pawl.

4. A lever formed of sheet metal bent in U-shaped cross section for part of its length, a cooperating metal fulcrum member, one edge of which is introduced between the walls of the U-shaped member in appropriate position and secured between said walls, said fulcrum member adapted to engage a suitable fulcrum point.

5. A lever formed of sheet metal bent in the form of a U-shaped section for part of its length to give strength and rigidity thereto, a fulcrum member, one edge of which is introduced between the walls of the U-shaped member and secured therebetween, and bein suitably mounted to oscillate on a suita le pivotal point 'or pin, a

6. A lever formed of sheet metal bent in U-shaped cross section, a cooperating metal fulcrum member, one edgevof which is introduced and secured between the walls of said U-shaped form, an arcuate ratchet suitably mounted and a pawl mounted on the lever to cooperate therewith, one end of the lever being formed as a cylindrical sleeve to receive a spring and-push button, a rod connected with the pawl by means of which the same is engaged or disengaged from the ratchet, the other end of the lever being formed as a clevis or jaw and means for preventing said rod from rattling against said lever.
