METHOD OF MAKING FORGEID FULCRUMS.

Speccaton of Letters'Patent.

Patented Nov. 5, 1918.

Application led April 5, 1918. Serial No. 226,910.

To all whom t may concern:

Be it known that I, ARMAND I-I. PEYGKE, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Methods pf Making Forged Fulcrnms, of which the following 1s a specication.

This invention relates to a method of forming a steel fulcrum.

The object of this invention is to simplify and improve the method of making ahforged steel fulcrum and at the same time minimize the cost thereof.

This and other objects are accomplished by employing the method consisting first in providing a blank having a web and flanges, then forming a brake lever opening in the web, then forming the fianges at one end of the blankinto a shape to` cooperate with a brake 'beam compression member, and then forming a seat in the other end of the blank for the reception of a tension member.

rllhe invention is illustrated on the accompanying sheet of drawings in which Figure 1 is a plan view and Fig. 2 an end view of a blank.

Fig. 3 is a plan view, showing a blank as provided with a perforation through the web thereof and a portion of the web removed at the end thereof.

Fig. 4 is a plan view of the blank after the anges at one end have been pressed into a lateral position and the intermediate portion of the blank pressed to form side walls for the central opening.

Fig. 5 is a sectional view taken in the plane of line 5-5 of Fig. 4.

Fig. 6 is a plan view of the fulcrum,

after one end thereof has been provided with a tension rod seat.

Fig. 7 is an end view of the fulcrum.

Fig. 8 is a plan view of the completed fulcrum after the central body portion thereof has been twisted 40o with respect to the ends of the fulcrum.

Fig. 9 is a sectional view, taken on the plane of line 9-9 of Fig. 8.

Fig. 10 is a fragmentary side elevation of a modified form of fulcrum for the reception of a brake beam compression member, and

Fig l1 is a transverse sectional view of a modified form of fulcrum.

The various novel features will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.

Referring to the figures of the drawings, it will be noted that I have provided a blank 15 in the form of an irl-bar having a central web 16 andassociated flanges 17 and 18.`

In forming this brake beam fulcrum the lirst step taken is to punch out some of the `metal in the `central portion of the web 1G to form an opening 19 for the reception of a brake lever. At the same time one end of the web 16 is punched away to leave two arms 20 and 21, which in the neXt operation are pressed laterally into a position at right angles with respect to the body of the blank for securing the latter to the compression member of a 'brake beam. During the same operation the flanges 17 and 18 are pressed inwardly toward each other forming a depression intermediate the ends of the bar and at the same time providing side walls for the opening 19 in which are forged eX- tended bearing projections 22 and 23, which are recessed a predetermined amount, as shown at 24. During the next operation one end of the blank is treated by suitable dies to provide a lseat 25 for the reception of a brake beam tension rod, as shown in Figs. 6 and 7, after which the central body portion of the fnlcrum is twisted at an angle of 40O with respect to the ends of the fulcrum, as shown in Figs. 8 and 9. rIhe fulcrum is completed by drilling or punching openings 26 in the arms 20 and 21, whereby the latter may be secured to the brake beam sion member. I-Ioles also are drilled or punched at 27, as shown inFigs. 8 and 9 for the reception of a brake lever pin therein.

If desired, one end of the fulcrum may be provided in the form of a band 28, as shown in Fig. 10, for embracing the compression member 29 instead of securing the arms 20 and 21 to the compression member by rivets.

Also instead of pressing the intermediate portions of the flanges 17 and 18 bodily toward each other, as shown in Figs. 4 and 6, the edges 30 of the flanges may be turned inwardly toward each other for forming lateral supporting portions for the brake lever.

It will be appreciated that during these operations the metal is heated to the proper temperature to facilitate the operations.

It is my intention to cover all modificacompres- CII tions of the invention falling Within the spirit and scope of the appended claims.

I claim: Y 1. The method of forming a forged fnlcrnin, consisting first in providing a blank having a web and flange, then perforating the Web for the reception of a brake lever `and' removing another part ofthe Web to form an arm of a portion of the flange to` C0- operate With the brake beam compression member, and then providing one end of the blank With a seat for a tension member.

V2. The method of forming a forged'ful- Crum, consisting first in providing a blank 'having a -Web .and flange, then perforating the web for the reception of abrake lever .and removing another part of the Web to lfoi-m an arm of a portion of the flange to coperate with the brake beam compression member, then providingfone end of the blank *with a seat Vfor a tension member, and then givingthe intermediate portion of the fulcrum and the ends thereof a relative twist.

V3. The method of forming a foiged fulcrum consisting first in providing an H .shaped bar 'having a web and flanges, then kpunching out portions of said web to form kan opening for abrake lever and for forming arms to coperate with a lbrake beam compression member, then forming a seat in one end of the blank for the reception of a tension member, and then twisting the central part 0f the fnlcrum -at an angle With respect to the ends of the fulcrum.

v45. `The method of making a forged fulcrnm consisting first in providing an H shaped blank having a Web and flanges, then removing portions of the web to foi'm an opening for the reception of a brake lever and vfor forming arms of the flanges at one f "end of the blank for cooperation with a compression member, then pressing the flanges of the blank intermediate theends thereof for forming walls for the lever opening, then forming a tension rod seat in one end of the blank, and then twisting the middle portion of the `blank at an angle with icspect to the ends thereof.

7. The method of making a forged fnlcrnm consisting first in providing an H- shaped blank :having a Web and flanges, then removing portions of the Web to form an opening for the reception of a brake lever and for forming arms of the flanges at one end of the blank for coperation with a Compression member, then pressing the flanges of the blank intermediate the ends -thereof for forming Walls for the lever opening, then forming a tension rod seat in oneend of the blank, then twisting the middle portion of the blank .at an angle with respect to the ends thereof, and then providing the Walls of the lever opening with holes for a brake lever pin and providing the arms with holes for securing said arms to the compression member.

Signed at Chicago, Illinois, this 28th day of March, 1918.
