CAN-STAMPING moms.

Specification of Letters Patent.

Patented March 2, 1909.

To all it may concern:

Be. it known that 1, CHARLES 0. BROWN, a citizen of the UnitedStates, residing at Le Boy, in the county of Genesee and State of New York, have invented new and useful Improvements in Can-Stamping Machines, of which the following is a specification.

This invention is an improved machine for stam ing dates, identifying marks, labels or the ike on cans containing vegetables, fruits or other articles and it consists in the construction, combination and arran ement of devices hereinafter'describ ed and c aimed.

In the accompanying drawlngs, Figure 1 is a side elevation of a can stamping machine embodying this invention. Fig. 2 is a vertical centra sectional view of the same. Fig. 3 is a top plan view of the same. Fig. 4 is an elevation of the same at right an Ice to Fig. 1. Fig. 5 is a detail sectional view on the plane indicated by the line a-a. of Fig. 1.

A block 1 constituting a base is provided, which may be secured to one side of a table, stand, counter, or other object a by means of the screws or other suitable devices 2. The said base block is provided with a vertical central opening 3 inwhich is laced the lower end of a vertical shaft 4. T e same is firmly clamped to the said base block as by means of a set screw 5. A bracket 6 has its inner end provided with an opening through which the shaft 4 extends and is secured to the said shaft by means of a set screw 7. a At the outer end of the said bracket is a bearing having a vertically disposed shaft 8 which is provided at its upper end sad 9 which carries an inking pad 10. On the said shaft, at a suitable distance from its lower end, is secured a disk 11 by means of a set screw 12 which operates in a threaded opening inits hub portion and the said disk is provided on its under side with ratchet teeth 13 so that the said disk constitutes in eflect a ratchet gear.

A vertically dis osed revoluble tubular sleeve 14 is mounte on the shaft 4 and bears on the inner portion of the bracket 6. At

the lower end of the said sleeve is a spider 15 having a pluralit of radially extending arms 16 with whic the successive cans engage as they are fed through the machine so as to rotate the spider and sleeve. A head 18 has a central opening through which, the

with a circular ortion of the sleeve 14 extends and upper epending hub portion provided with has a a set screw 17 which clamps said head to said sleeve to rotate therewith. On the upper side of said head and disposed concentrically with reference to the shaft 4 is a cylindrical cam element 21 which has a lurality of cam shoulders 22 each of which as an inclined upper edge 23 and a vertical edge 24. The said cam element is secured on said head by means of screws 25 which engage threaded openings in lugs 26 which proj ect from the upper side of said head, thereby said cam element is caused to revolve with the said head. The latter is formed with a plurality of radial arms 18* each of which as a vertically threaded opening near its outer end. Radially disposed extension arms 19 are provided which are longitudinally recessed in their upper sides to receive the arms 18, bear under said arms and are provided with longitudinal slots 20. Set screws 27 operate in said head and in the threaded openings near the outer ends of the arms 18 and serve to adjustably secure said extension arms to the arms of the head and enable such extension arms to be adjusted radially so that their outer ends may be projected to any desired extent from the center of the said head. Plunger rods 28 operate in vertical openings in the outer ends of the extension arms 19. Each of the said plunger rods has an enlarged head 29 at its upper end. S rings 30 are placed on said plunger rods an bear between the outer ends of the extension arms 19 and the heads of said.

plunger rods and serve to normally support the latter in an elevated position. A suitable stamping device 31 is detachably sccured to the lower end of each lunger rod 29.

A collar 32 is rigidly secured to the shaft 4 near its upper end by a set screw 33 and is provided with o )positely extending pairs of ears or lugs 34 etween which are plvotally mounted hammer arms 35. On each hammer arm is secured a radially adjustable hammer head 36 by means of a set screw 37. Itwill be observed, by reference to the drawings, that one of the hammer heads is disposed directly over the inking pad 10 and that the other hammer head is dlsposed diametrically opposite such inking pad.

When the sleeve 14 is revolved by means of the spider 15 which is itself revolved by the successive cans, the head which carries the stamp operating Iplun er rod and the cam element revolves wit sai sleeve so that each stamping device in succession passes over the sa1d mkmg pad. The hammer arms, being pi'votally connected to the collar 32 which is rigidly secured to the non-revoluble shaft 4, donot rotate with the cam element, but the latter passes under such hammer arms and as each of its cam shoulders passes in succession under one of the hammer arms, its inclined edge raises such hammer arm and as its verticaledge passes from under such hammer arm, the latter drops, causing its hammer head to strike on the upper end of one of the stamp operating rods so as to depress such operating rod or plunger 28 a ainst the' tension of its spring 30. ence t e stamp operating plunger which happens to be disposed above the inking gird will be brought into contact with such 1n 'ng pad to cause its stamping device to be inked thereby. The

to the said bracket by a screw 41.

shaft is provided at its inner end within an can to be stamped is placed on the support a and as the arm 26 carrying a stamp operating plunger rod passes over such can, it comes under one of the hammer heads as the latter descends so that such hammer head forces such plunger rod downwardly and causes such stamping device to make its imprint or mark upon the can, as will be understood. It will be understood that as one of the inking devices is automatically inked and another is automatically driven down upon a can at each artial rotation of the head, the machine 1s very rapid in its action and serves to stamp cans as fast as the latter can be placed thereunder and the said head partly turned, thereby enabling a single attendant to stamp a large number of cans in a comparatively short time;

It is necessary to rotate the inking pad by step by step movement in order to present a new surface thereof to the stampin devices to keep the latter properly inked an I therefore provide devlces which coact with the ratchet gear 13 to thus rotate thehead and hence the inking pad, which devices I will now describe.

The bracket 6 is provided with a bearing 38 having a rock shaft 39, the said bearing havin a removable outer portion 40 secured Said rock upwardly extending tappet arm 42 which is wlthin the radius of the arms 16 of the spider 15, so that as said spider rotates, each of its said arms in succession en ages said tappetarm and partially turns sai rock shaft in one direction. A spring 43 is attached to the said bracket arm and operates to move said rock shaft in the reverse direction; At the outer end of said rock shaft is an upturned rock arm 44 to the upper end of which is pivoted a pawl 45 whic is held in normal enspider 15 and the sp n 43, t e said'pawl serves by coaction with t e said ratchet gear to partlally rotate the head, which carries the inking pad at each partial rotation of the: sp1 er.

Having thus described the invention, what I claim as new and desire, to secure by Letters Patent is: .7
