This expedient is adopted 'A5 mustated a' @am 12 gradually tapers out because in tennis racket heads the length Varies Wardly and downwardly and may be made of somewhat, and it is desirable to make the positioning form small enough to serve for any size tennis racket, thus making it necessary only to by the shape of the racket to be punched or dfferet lerfgth n larkmg menbrs for Saud marked, being round Yfor a squash racket and ma por lons m Var.10us size me e s' b.

The shorter markcorrect relation to each other. Said positioning ing members 16 alternate with said longer memform 1-8 is purposely made shorter in height than bers 14 and their heads are directly in front of the racket 21 to be marked, so the operator can 11o ered at the sides thereof with a hardened steel band 13. The shape of the cam is determined 70 'adapted to be directly actuated by said cam, a

readily see to line up the racket with

saidguide marks

20 and 22 opposite each other.

Said positioning form 18 is supported by a table 25 in which a recess 26 is cut to receive said form 18 and prevent any sidewise movement. Screws 27 hold said form 18 to said table 25 as shown in Figure 3 of the drawings. The cam 12 extends through an opening in said table 25, and the racket 21 to be marked rests on the top thereof. y l y To actuate said cam upwardly any suitable and well known means may be employed. The mechanism I have shown consists of a flange 28 which is held by screws 29 to the under side of said cam 12, into which flange the upper end of an upright member or vertical lever 30 screws, the lower end screwing into a lug 31. A forked, horizontal lever 32 is fastened to said lug 31V by a pin 33 which extends through said lug 31 and forked end of said lever 32, said pin being held in place by a cotter pin 34. A standard 35 is forked at one end about said lever 32 by means of a pin 36 which serves as a pivot and which is held in place by a cotter pin 37. At the end of said actuating lever 32 a foot treadle 38 is formed, downward pressure on which Vraises said lever 32 and the other movable parts to which said cam 12 is connected, forcing said cam upwardly and said marking members outwardly.

Fastened to said standard 35 is a stop member 40 which is recessed to receive a rubber bumper 4l on said lever 32,'which parts 40 and 41 limit the downward movement of said cam 12, and determine the normal position thereof.

Said standard 35 is fastened to the floor 42, and a coil spring 43 which is fastened around said pin 33 at oneend is held tosaid floor 42 by an eye bolt 44 imbedded in said floor. Said spring 43 insures the immediate return of the cam to normal position when pressure upon said foo-t A treadle 38 is released.

'What claim is:

8. A marking machine comprising a cam, means to move said cam, marking members adapted to be actuated by said cam, a collar on each of said marking members, other marking members in alternating positions to said rstmentioned marking members, said collar on each of said first-mentioned marking members con-j tacting with two of said other marking members, means in contact with said other marking members adapted to return them to normal position after being actuated, a positioning form for the article to be marked surrounding said cam having holes extending therethrough into which al1- means to.

cam, collars on said marking members, other marking members contacting with said collars, springs around said other marking members adapted to be compressed when said cam actuates said marking members, a positioning form adjacent said cam having provision therein to permit said marking members to extend into and beyond it, and means to support said form.

10. A marking machine comprising a vertical cam which tapers outwardly and downwardly, means to move said cam upwardly, a positioning form, a table supporting said form, relatively long and short marking members distributed in alternating positions, the heads of said long members contacting with said cam, collars on said long members, the heads of said shorter members being in contact with said collars, and coil springs around said shorter members abutting against said form, said form having holes therein into which said marking members extend and may project beyond.

11.
