To all whom it may concern:

Be it known that I, JOHN F. VHITE, a citi- Zen of the United States, residing at Mount Morris, in the county of Livingston and State of New York, have invented a new and useful Improvement in Can-Stamping Machines, oi which the following is a specification.

This invention relates to machines for marking or stamping cans and other receptacles or articles. While the machine hereinafter described is designed more es` pecially .for printing characters on the ends rot' filled cans whereby the contents of diii'er-l ent cans are indicated, the invention not necessarily restricted to machines for such purpose.

The object of the invention is'to provide a machine ot' simple and desirable construction capable of rapidly marking cans orother articles as they are moved past the stamping mechanism by a traveling conveyer.

In the accompanying drawings, consisting of two sheets: Figure l is a fragmentary transverse sectional elevation ot.' a stamping machine embodying the invention'. Fig. 2 is a perspective view thereof, on a reduced scale. Fig. 3 isa detail section of one of the stamps. Fig. 4 is a perspective view of a detached stamp for use in the machine in place of the stamps shown in the other gures. Fig. 5 is a front elevation, partly in section, ot' the machine, on a reduced scale. F ig. 6 is a plan View partly in section, on a reduced scale, showing diiferent means for driving the stamp carrier.

Like letters of reference refer in the several figures.

The machine comprises, briefly stated, a traveling conveyer tor the cans, or other articles, a series of stamps or marking devices, an inking pad on device, and means whereby the stamps' are successively moved opposite to and pressed against the inking pad to receive ink and are then carried to a position opposite to the path of movement of the cans or articles and pressed in successuccessive cans or articles to to like parts make the impressions, and retracted to repeat the same functions. The stamps are moved in unison with the articles by means engaged and actuated by the articles, or by suitable mechanism connecting the article conveyer and stamps.

A represents the eonveyer or carrier for the cans or other articles to be marked. This conveyor may be constructed and operated in any suitable manner. ln the machine illustrated the cans or articles are supported by a stationary table or guide way a on a suitable frame o', and the conveyor consists'of an endless chain or belt provided with dogs which project up through a slot in the table to engage and move the cans or articles along the same. vThe conveyer can be driven either intermittently or continuously by a wheel f'around which it passes, or by other means.

B represents a movable carrier or supporting head for a series of stamps C. The carrier preferably consists of a spider o having radiating arms b, each carrying one of the stamps, t-he carrier being so located above the article conveyer that inthe rotation of the carrier the stamps are brought in succession to printing position over the successive articles in the conveyer. The carrier is movably mounted, preferably rotatably, in any suitable manner, for instance, it issecu-red to the upper end of a sleeve or hollow shaft 'b2 which surrounds and rotates on a' stationary vertical spindle b3, which is fixed to and rises from the frame a of the niachine or other suitable support.

The stamps C, in the construction shown in Figs. 1,2 and 5, consist of typewheels which are provided around their periphcries with type c and are journaled in any i suitable mannerat c on vertical stems or rods c2 so that the wheels can be turned to place any desired type thereon at the bottom of the wheel, where it can print upon the top of the article i by depressing the wheel when in printing position. The Wheels are releasably held from turning when adjusted by suitable means, for example, by

spring fingers cl secured to the stems or rods c2 and adapted to yieldiiigly engage stop projections d on one face of the Wheels, see Figs. 1 and 3. The stems or rods of the stamps preferably pass through guide holes e in the arms of the carrier in which they are adapted to slide lengthwise or vertically and are connected at their upper ends at c to operating levers E which are pivoted at their inner ends at e2 to lugs or parts on the rotary carrier B and rest and slide at their outer ends on a stationary circular track F. The track can be supported, as shown, by a skeleton frame f ,fixed to the upper end of the spindle b3 on which the carrier rotates, or in any other desired manner. This track E is provided at a point over the can or article conveyer A with a notch or depression Gr having an abrupt vertical face g and an inclined or4 camv face g', the location of the notch being such that each operating lever is brought opposite to the notch by the rotation of the carrier B and will drop into the same over the abrupt face at the time when the stamp connected to the lever is in printing position over an article inthe conveyer, thus permitting the stamp to. descend and make the impression on the article. The operating arm E will then engage and ride up the inclined face of the notch onto Vthe horizontal upper face of the track. The track F is provided .with a second notch or depression H, similar to G, located in avsuit able lpoint to allow the descent of the stamps against an inking pad or device, to be'de' scribed, as they are brought successively over the same by the rotation of the carrier. The stamps are preferably forcibly lowered or pressed down to insure proper impressions by suitable means,.such as springs I connecting the operating levers Fand armsb ofthe rotary carrier B. t

In the construction shown in Figs. 1, 2 and 5 the carrier is rotated to move the stamps in unison lwith the ,articles 4to be printed by the engagement of the articles themselves with the arms of a star wheel K secured to the lowennd of the hollow carrier shaft b2 with its arms projectingover-` the conveyer A in the path of the articles carried thereby..l ,As the. cans or articles move along they engage the arms of--the wheel and .turn the same and the carrier so that' a stamp isbrought around into printing posit-ion directly-over eachcan or article when it reaches the'printing position. By

v thus 'actuating theV carrier through the instrumentality of thearticles, it is moved 'one' step 'by each article 'to elfect theprinting of the saine, but remains'at rest in the event that an article 'is not presented by the con' -veyerto the stamping mechanism.

articles but by means other than the article itself connecting thel conveyer and the actuating device for the stamp carrier. The connecting mechanism shown intliis figure, by Way of example, consists of a shaft L connected by bevel gearsl to the shaft 'Z' carrying the ccnveyer drive Wheel a? and provided with a bevel gear P'Which meshes with a bevel gear Z3 which is secured to the hollow shaft oTl ofthe carrier and replaces the stai' Wheel K shown in the other construction.

M represents the. inking device which preferably consists of a horizontal ink-saturated pad on a disk supported beloW the path of tlie stamps in position to be engaged by the stamps w-lien theyl are lowered by the dropping of their opera/ting -levers E into the notch 'or' depression H of the circular track F. The disk is rotated horizontally to present different parts of the pad to thestamps and pret'ent a local Wearing or drying of the ad, the disk in the construction illustrated ing secured to a' hollow vertical shaft m which is supported and turns on a stationary spindle m xed to theframe a of the ma chine. The disk is rotated by intermeshing gears m2 ma secured to the shaft m and to the hub of the actuating star. Wheel for the rotary carrier. The inking device could be' form adapted to the particular form ofthe articles to be printed or for making special impressions. In Fig. 4, for instance, a ring shaped stamp C is shown which is provided with a stem for mounting it in 'the carsie rier in the saine manner as the other stamps.

' The wheel stamps can be replaced by stamps ofthis or other form.

The operation of the machine is as follows: The 'cans or other articles are placed on the table a and moved by the conveyer A past the stamp carrier. The latter is rotated bythe engagement of the articles with theV arms of the star Wheel K or bygearin connected-with the conveyer, as explains As l the cari-ier rotates, each stamp is brought over 'the inking pad and pressed down against the same and inked aidris then again raised and moved tothe printing position.

inv this position, the actuatinglever E therefor drops into the notch Grv of thetrack .F and the stamp is pressed yagainst the toppf ie stamp .is again. im'inediatciy 'lifted oft of the artic e by reason ofits actuating' lever ri'd'- ing upon the inclined face g of the notch G,

4so that a clean sharp impression .is left even l though the conveyer and article are notarrested in the printing position. l The stamp, means controlled by the movement -4moving the stamp against the article to make Vof the conveyor for mcving tht stamp to stamps are thus successively inked andV pressed against the successive articles on the conveyer to mark each article.
