SHELL-MARKING MACHINE.

Specification of Letters Patent.

Patented Jan. 15i1918.

Application filed October 29, 1915. Serial No. 58,733.

To all whom it may concern -,Be it known that I, Joirn Moornny Brown, of the city of Hamilton, 111 the countypf Wentworth, Province of Ontario,

Dominlon of Canada, have invented certain new. and umful Improvements in bhell- Marking lvlachines, of which the following is the specification.

My invention relates to improvements 1n shell marking machines, and the ob]ect of the invention is to devise a machinejor marking the base of shells with the required data, in which the pressure is imparted gradually to each individual type, thereby eliminating all crushing strain tending to deform the type, and in which the depth of the impression may be regulated; and it consists essentially of a marking chuck secured to the base of the shell and carrying individual type slugs, a saddle holder in which the body of the shell rest-s, a pressure member bearing against the nose of the shell, and a revolving pressure chuck designed to successively bear against each invidual type piece carried in the marking chuck, as hereinafter more particularly explained by the following specification. v

Figure 1 is a side elevation of my machine shown the marking chuck, pressure memher an revolving pressure member in section;

Fig. 2 is e cross-sectional view on line ti 1, Fig. 1..

1 indicates the bed of the machine. 2 1ndicates the base of the saddle member which is slidably secured in position by screws 2 on the slideway 1 forming part of the base of the machine. 3 indicates the saddle which extends upwardly from the base 2 and 1s provided with a scmi-octagonalrecess Bfiextending longitudinally of the machme. 3' indicates a, series of grub screws whichiare threaded into each an face 3 3?, and 3";of' the recess 3" and on which the body of the shell 4 is'designed to rest when in ositi'on. 5 indicates a cap member also provi ed with s: semi-octagonal recess 5* opposing the re cess3" and also provided with grub screws fi' bcilrin against the upper peripheral portfltm of the shell when the cap untho plates 10 and 11 are connecte ing a link 6* pivoted to the projecting portion of the saddle piece 3 at its lower end and extending upwardly through the notch 5 formed in the outwardly extending flange 5 of the cap 5. 6 indicates a lever pivoted at its inner end to the upper end of the link 6 and provided with a depending eccentric portion (Sibearing against the flange portion 5" of the cap 5.

Although I have shown this form of clamping means it will, of course, be understood that various other means might be employed for accomplishing the same purpose.

The type'slugs 9- are set in the annular space 7 in annular series with the notch 9 facing outwardly.

members

25, 24 and inner end of the shaft 20, being, secured in position by any suitable u'ieans.

28 indicate rollers journalecl, upon. the pin 27 at diametrically opposite points of the revolving pressure niei'uber Q3 and in such a position as to bear against the outer end of the type slugs exteruling 'lrorn the 25 marking chuck 7i 2 indicates av ball-blur ing member located bet ween the rota ry pressure nien'iber and the lard 2:2.

Having described the prineipul parts in volved in my invention I will. briefly describe the operation ot'ithe same.

The marking chuck is first sccurwil to the base of the shell by means of. tiib seescrcw 7". The shell. is then placed in the saddle 3 upon the inwardly projecting grub screw-vs 3 and with the nose of the shell eidiesuline into the recess 19 of the blocl; l The grub screws 3' are adjusted so as to insure the proper horizontal alinemcntoi the shell when in position The cup 5 is then closed 40 down upon the top of the shell and clamped in position by means of the le securing the shell in a stat onary The slnrft 2O then mutat d so rollers 28 are carried N cely, in. or #fioutw-rrdly projecting nds the ilrgu; The lEEllRFl-Wli, l 16 is H turn ll .1 s l pressuiu n a line parallel with tin longitudinal axis oi the shell. tl er lri ca1'r ing the shell, saddle member and ndard 18 longitudina ly toward the rotary ssure member their y pressure between the rollers and the outer end of th them forward against the base of the shell to form the in'ipressiou.

It will be seen that the type 9 are arranged in annular series and that. llH.-=F( ii1l.(., the -rollers 28 travel successively over the type. and, therefore, form the impre ion not by one single pressure but by a series of coin-- paratively light pressures repeated as the rollers QSJTJEIkEl their revolutions over the type. i

I: will be readily understood that if an impression is made by one operation or by ype -l so as to gradually force great pressure made instantaneously that there would be a lcmleucy to crush the type and thereby (lestrcy its usefulness. By my machine the pressure. is exerted gradually and successively on each of the type members and, tl'nzre'lore, the impression is gradually made and any danger of crushing the type eliminated,

What I claim as my invention is:

l. in a shell marking machine, the combination with the shell holder, and a mark in ehuclc adapted In be secured to the base of the shell and to carry a series of suitable type slugs, ol. means for gradually exerting pres-mire sir c rely on each type piece to :l'orni an iin i sion on the base oi" the shell.
