Specification of Letters Patent.

Patented May it,

Application filed October 25, 1915. Serial No. 57,896.

fl '0 all IF/L077} it may concern:

Be it known that I, Hn'ozo Kawivrn, subject of the Emperor of Japan, and resident of Seattle, in the county of King and State of Washington, have invented certain new binations of parts which will be hereinafter described and particularly pointed out by the claims which terminate this specification.

The object of my invention is to improve and simplify apparatus of this class.

In the accompanying drawings I have shown my device in the form of construction which is now preferred by me.

Figure 1 is a side elevation of my device, parts being broken away to better show the operating parts.

Fig. 2 is a top view.

Figs. 3 and 4 are side elevations, partly in section, showing the principal operating parts, the position of the parts being different in the respective figures.

Fig. 5 is an end view of my device, partly broken away, looking toward the delivery end.

Fig. 6 is an enlarged section of the labeldelivering mechanism. I

Fig. 7 is a sectional view of the same mechanism, taken on the line 77 of Fig. 6.

Fig. 8 is another section through the label delivering mechanism taken on line 88 of Fig. 6.

Fig. 9 is an enlarged section through the pivot of the cell segments.

The cans are delivered in stacks consisting of a series of cans placed end to end, these stacks having their axes horizontal. This delivery is by an endless chain 1, having rollers 10, between which the cans 11 rest.

From chain 1 the 'cans roll upon an inclined table 2 which has side guard members 20 supported in a yielding manner, as by pivoting at 21 and pressed inwardly by springs 22.

The cans are held during the application of the label, within a cell within which theyare rotated to wrap the label about them. As ShL n, this cell is composed of a fixed segment 33, a segment 34 carriedby arm 3 which is oivoted at 31, and a segsuliiciently greater diameter than the cans to permit the free passage of the label about the can. i

A spring 35 normally holds the outer swinging section 30 in closed position. A shoulder at 36, limits the closing movement. A link i pivoted to arm 3 at it), has a cam roller upon its other end which travels in cam slot 50 of cam disk It also travels in cam slot 41 contained in a part of the frame.

As the arm 3 swings down, the weight of can 12 then in the cell, is suliicient to over come spring 35 and open the parts to the position shown in full lines in Fig. l. Bars relation when the cell is closed, as is shown 16 and has laterally projecting swinging endv 19 positioned to engage link 38 to break or buckle the joint at 39, permitting closure of the cell sections 30 and 34-.

Three sets of rubber covered rollers, 6, (30 and 61, are mounted to project slightly within the circle of the can receiving cell, and constitute the can supporting and turning means. The rollers 6 are secured to the main driving shaft 31, upon which the arms 3 are pivoted. Rollers 6, 60 and 61 are idlers. Shaft 31 and rollers 6, turn clockwise, as the machine is shown in Figs. 1, 3 and 4.

Pivoted at 71 upon a post 23 extending from table 2, is an arm 7. One end has a. weight 70 secured thereon, the upper surface of the'lever being notched, as at 72 to facilitate adjustment of the Weight along the lever. Its other end is pivoted to a link 73 which is pivoted at 40 to arm 3 to which also link 4 is pivoted. Another arm or bar 74 is pivoted to the axis 62 of rollers 61, and carries a pin 76 which enters groove 77 of link or bar 7. Bars 74 cairy a trans;

, abar extending across the machine and acts as stop for the cans and with bar 75, to support a l1ne of cans. The spacing of bars 75 and 78 is such that as they are swung up they are separated to drop the cans between them :and into the opened cell.

ipaste or adhesive tank 89 has one side 85 perforated with holes 86 near its bottom .ed'ge',w and an extension 87 ofv its bottom beyond {this perforated side wall.

A, wheel 52 lies above the paste tank and the bunch .eral cans at ion'ce.

of labels are placed with the side of the bunch against the outer face of the perforatedi wall' l and their upper ends bentover wheel p The nppefr end of the, labelsv rest upon fixed jba s54, between which are mounted 1 feed bldeks =55 to reciprocate "along the bars.

- 80 represents the side walls of the recess or, spafc jewithin which the labels are placed.

Ai complete Qinaehinewould preferably have the essential parts duplicated to label sev- A weight 81 having pinslentering inclined guidinggroovesf S2 is placed on top of each pile. This is odnn ected'bya fiexibleqweb 88,

with another, wight,83 which engages the outer surface of the loiver...en d of the pile of labels, lugs dfipins projecting from; plate 83 outer grooves 84. These weights hold the ,labels, at one end in position for feeding, and

"at the otherend' close againstthe perforated plate .jgst.

To the feed block 55 is connected a lever v58, 59, which 1S mounted on a transverse bar 56. To JheloWei vZ'end of this lever'is pivoted a lever .9 which is fulcrum/ed at 91 and has a slotted-end QO embracinga pin carried by the cam roller42.

Transverse bar 56 is mounted in slots 63 in the frame. I As lever 9 is oscillated it swings lever; 58," 5.9,, which first raises {blocks to slightly i'jaise the labels from thegbars 541 the leizer 58 has a finger 57 'avhich/then crin-ltatrtp 'with'block 55, preventing further 'a'ngularjnovemnt, further movement ofjleyer 58,59 causing a forward sliding move fnent of block block is of a character which facilitates en.-

The, upper surface of this can. It then enters the can -re,-'

' The shaft 53 of drum 52 is mounted to slide in slots 51 in frame members. movements are caused by links 44 which con- Its nect it with levers 9. This shaft carries a ratchet wheel 45 which is successively engaged by fixed pawls 46 and 47 to give it a small, forwardly rotative impulse for each reciprocative movement. This movement of the ="drum relieves the pressure upon the lowermost label'and' assists in feeding it forward.

The upper surfaces of the feed blocks 55 are composed of rubber, or are otherwise niade so as to get good frictional grip on the labels.

Having thus described my. invention, what ,I claim as new, and desire to secure by Letters Patent of the United States of America, is:

1. In a can labeling machine, in combination, a can receiving cell closely embracing fthe periphery of the can, rollers projecting within said cell to form carrying supports for the can, means for turning the can through said rollers and means fol-passing a label within said cell to be wrapped about the can?" 2. A glabeling device for cans having a fixed paste reservoir with a perforated wall at one side, means'for supporting a bunch of labels with their inner face at one end hearing against said perforated wall, and means for withdrawing the label which contacts said perforated wall and applying it to a can.

3. A labeling device for cans having anadhesive receptacle provided with a perforated side wall, means for supporting a bunch of labels with one end in vertical position with a side face of the bunch against said perforated side, means for holdin the upper end of the bunch in curved position with the label which contacts with the perforated wall at the concave side of the curve and means for engaging said inner label to withdraw it from the pile and to apply it to a. can. I
