- Be it known that l, GEORGE D. HUNTER, a citizen o the United States, residing at Anlonrn Park, in the connty of Cook and State ci illinois, nave invented certain new and use inl improvements in Crinipers for Certrige- Shells; ancll do hereby declare the following to be a full, clear, and e'xact description of the invention, snob as will enable others skilled in the art to which it eppertains to make an'd use the saine,

My invention relates generally to devices for crimping 'the outer or front ends of the and particularly to improvements in-tliis class of devices which rensier them more durable than usual and effective in operation or capable of smoothly am?, perfectly closing the ends of salti cartridgesliells einer the powder, sliot, andairads bavebeen placed in their respectivenpositions therein; anelli, consists in. the pecnliarmes of construction and arrangement. or combination of parts and features hereinafter fully disclosed in the description, drawings, and clainis. v n g .v

'The object of my invent1on-1s toprovicle a crimper for-cartriflge-sliells which will be more durable or last longer i n ployeil, which Will avon'l ine great amount or friction usually pertaining to crinpers mantle factnre wholly of brass or other niet-al, which will lessen the nsnal tendency to tear or ronghen ille enfle ci' the paper alare-ils of ca trifigee while they ere being'l intnrned or criinpefl, wliioll will be capable ci employment in stationery` portable inaclnnes'ior loadingenii crimp ng; cert-ridgeeliells, in separate crimping-maehines, in senarate machines 'for ont-ting and crimping cnrtridge-sliells which may have been filled b band, or 1n a ma chine., for instanoeg, of the character of that disclosed in the Letters Patent granted to ine May 29, 1888, No. 383,529, endA which will "loe simple in. construction., easy to operate, and cliean to manufacture '.lbisob] ect 1s accom# plished by the improved construction and arrangement or combination of the parts and features of this invention, which is embodied in the slightly tliiiierent forms or constructions shown in tbc accompanying drawings cont'nan those usually ein' Serial liloI 366,988.` (No model.)

stitnting part ci this specification, in which tlie saine reference-numerals indicate the same or equivalent parte, and in which@ Figure l represents. sectional and front views of one of my improved. crimpers for cartridgesliellsg Fig. il, similar views of a modified forni or construction. of the sarna, and Fig. 3 similar Views oi? another slightlymodiiied forni or construction thereof.,

In the drawings, the numeral l indicates my improved crimper, which, as shown in Fig. l of the drawings, is composed of the -rnain holder 2, the auxiliary holder 3, the glass crimpingdislr. 4f, the cement 5, and the shaftliea G. These main and auxiliary bolder are mede of metal, and. the former is constructed in the shape of a collar, which is inyterioyfly screw-threaded and enlarged along its rear port-ion '7, contracted. along its front portion S, and formed with an inturned flange 9 around its frontcnil` or rirn, While the latter has the shape of a flat-bottomed cup, which is held in place within the former by ille exteriorly-screw-tlirea letl and enlarged shaft-beati (i, which is removably lttetl in the 'former and when in place holds the front enil or riin of the latter firmly against the intnrnfeci flange il ci' tile former. ln. the chamloer of the Cupehaped auxiliary holder il is iiifetl the glass crimping-llink -i-, Wlricli is shaped to substantially correspond to the iii-- terior thereof is llrlnly seated. or einbefl- 'dell in. the layer ci plaster-of-paris, whitolead, or other snitabe cement 5. On erin the rear soi-face of this glass crimping-disk are formed the small ribs or grooves lO, which are pressed into tlie cement for preventing said disk from turning and for holding the same lrinly in. place in all direciions. The anxiliary bolder 3 is prevented from forward dis placement by the intnrneil flange 9 around the front end of the main. bolder 2, which will 'keep it from outward or forward movement; also, said auxiliary lioltlcr, with its previouslyseate l glass disl;u is placed within said main iholder by being; passed forwardly through the opening in the enlarged rear portion thereof before the sheft-lica l G is introduced. The fro-nt or operative surface et the glass crimping-disk i is formed with the miseri center il, t'hc rin l, 'the intermediate linnnlar groove 1S, and the bosses or slightiyeraised projections le near the bottom of said groove.`

A car shell while being closed or crimped is "required to be firmly supported at its rear end and prevented from turning. A. device for accomplishing this result may be the same as the chuelecups or shell-rests used in connection with the ordinary cartridge-crimpers, or it maybe the same as the adjustable chuck wheel disclosed in my abovonamed patent, which is capable of receiving and iirmlyliolding the rear ends of cartridges of various sizes.

In the niodied form of construction of my improved erimper shown in Fig. 2 of the drawings the glass crimping-disk Il has the same construction and is secured in the cement the same as the one above described. The main and auxiliary' holders 2 and 3, however, are dierently constructed from those above described, as said main holder is formed integrally with the shaft-head G, as it is interior-ly serewthreaded along'its front portion,and as it has no in'turned flange around its front end or rim, but may have, if desired, while said auxiliary holder is exterior-ly screw-threaded for holding it in place or in engagement with the Vinteriorly-sorew-tl1readed i'rontportion of said main holder.

ln the additional modified. form or construe- ''ion of my improved crimper shown in Fig. 3 of the drawings the main and auxiliary holders and 3 are connected by screw-tlireads in the same manner as the corresponding parts in Fig. However, hey and the glass crimping are differently constructed from the corresponding and equivalent parts shown in Figs. l and :l in the following particulars: The main holder and the shaft-head are made hollow, and wi th the auxiliary holder and the glass crimpingdisk are formed with the central registering openings 15, which are designed. to receive the adjustable or movable CcnterILG, which is in common use for pressing upon the upper wads of charges-in cartridgeshells for holding them down While the crimping of said shells is taking place; also, the auxiliary holder 3 of this embodiment of my invention is formed at its front end or rim of facilitating 'the making of its internal` I do not herein broadly claim a crimper for cartridgeshells provided with a glass crimping-disk, as this and certain other improve# ments in such devices form the subject-matter or' another application for Letters Patent,

led by me simultaneously herewith, Serial No. 866,989; but it will be obvious from the foregoing that my present improvements will avoid all the friction al disadvantages that are incident to the use of brass and other wholly metallic crinipersnn which the bosses or slight lyraised projections wear out in very short time and roughen the paper from which the shells are made; that the glass disk will make smoother crimps in shells than when wholly metallic crimpers are employed; that the seating or embedding oi' said glass disk in cement holds it firmly in place, insures it against easy breakage, ailords it a true or level scat within the flat-bottomed auxiliary holder, and permits the outside ot' the main holder to be turned 'true after said disk arid its holder have been placed in operative position within said main holder, whereas when the entire crimper is made of metal it is generally cast and then swaged to the desired size, which cannot be done with certainty or accuracy owing to the roughness and shrinkage ofthe metal, and thatacrimper provided with this glass crimping-disk will turn over or crimp dry paper shells of oartridges without any twisting strain thereon whatever, will operate with less friction than metallic crimpers, and consequently will require less power for its operation.

.Having thus fully described the construction and arrangement or combination of the parts and features of my invention, its ad-v vantages, and operation, what l claim as new 1s l. A crimper for cartridgeshells, provided willi a main holder, an auxiliary holder, and a glass crimping-disk arranged and secured within the latter, substantially as described.
