To all whom it may concern:

1 Be it known that I, FREDERICK W. WILD,

7 Jr.', of the city of Baltimore and the State. of

Maryland, have invented certain Improvements in Labeling-Machines, of which the 7 following is a specification.

This invention relates 1 rincipally to a peculiar construction of a abeling machine whereby certain parts of the same can be so "affixing of labels towns of different diameters, as will hereinafter fully appear.

In the description of the said machine which follows, reference is made to the accompanying drawings forming a part hereof,

Figure 1 is a partly sectional side view of Fig. 2 is an enlarged exterior side ,view of the entrance end of the machine, except that the front bar forming a part of the frame thereof is removed. Fig. 3 isatop view of the same, except that certain parts shown in Fig. 2 are removed, and the 'ar removed in Fig. 2 restored. Fig. 4 is a section I of Fig. 3 taken on the dotted line x.x. Fig. 5 is an enlarged exterior side viewgof the central portion of the machine except that the front bar forming a part of the frame is removed as in Fig. 2. Fig.6 is a top viewof the said parts of the machine with the'bar removed in Figs. 2 and 5 restored. Fi 7 isan enlarged exterior side view of the ,de ivery end of the machine with the bar before referred to removed. Fig. 8 is a to view of the same with the said bar restore Fig. 9 is a View similar to Fig. 6, except that a modified construction f pasting devices is i "illustrated; Fig. 10 is a end view of Fig. 9 A ,---looking in the direction indicated by the arrow. I

Referring now to Figs. 1 to 8 incluslve, of

the drawings, the frameof the machine con- Y sists of the longitudirfal and transverse bars respectively denoted by 1 and 2. The frame is supported by a stand which to facilitate I the removal of the machine from place to placeis provided with two truck wheels on a transverse axle 1). One of these Wheels is shown, and that is in Fig. 1 where it is repre- 0 sented by d. 3 and 4. are respectively, the entrance and the delivery runway for the cans,one of which cans isshown in Fig. 1 andmarked X. 5, 5 are endless conveyer belts whereby the cans are carried long1tud1- n5 nally of the machine in the labeling operaadjusted one with another as to admit of thetion, and the said belts are mounted on the pull s 7 and 9, the latter being considerably sma er in diameter than the former, for a purpose hereinafter described. The shaft of the arger pulle s 7 which are situated at the entrance end 0 the machine, is supported in the standards 10, the lower ends of which rest and are adjustable in height in the sockets 12. This construction allows cans of different diameters to ass under and of their being carried forward by the belts; and when the said standards are adjusted in height they are fastened by means of the set screws e. 14 is the receptacle for cement which is li uefied by heat, and 15 15 are wheels Whidli are rotated in the cement receptacle by means of any suitable devices to apply cement to the bodies of cans as they are carried forward and over the said wheels by the conveyer belts 5. The cement receptacle is held in place by bolts f which depend from the forward transverse bar 2 of the frame, and pass through slots in extensions 16 of the said rece tacle, as bestshown in Figs. 2 and 3, whereby the receptacle is made adjustable in position. 17 is a fixed plate so.

orted by the longitudinal bars 1 of t e rame, having rails g which extend over the cement receptacle 14 and upon which the flanges of the heads of the cans roll.

By reference to Figs. 3 and 4, it will be seen that the rails g are laced exteriorly of the cement wheels, an that between the said wheels are situated two supplemental rails .h which are fastened to the rear end of the cement receptacle, and elevated slightly above the rails g, as shown in- Fi 4. By this construction the cans imme iatel before reachin the cement Wheels are llfted from the rai s g by the supplemental rails .h, and after passing from them, roll on to the.

plate 17. The sup lemental rails h are set so as to be practical y on a level with the top of the cement wheels, consequently the same amount of cement is invariabl applied to the can bodies, which effect wou d not be the case should the cans at the time of the application thereto of the cement,-b'e supported by the flanges of the heads, for the reason that the flanges of cans vary in thickness or projection beyond the bodies. 19 is the spriu -held table upon which a stack of labels are placed, and by which the upper label is always held slightly below the surface of a label guide hereinafter described. 20 is the label guide before referred to, consisting of fixed rails t which are supported from the longitudinal bars 1 of the frame by means of the rods j, and the longitudinally adjustable rails is. These adjustable rails are seated in depressions (see Fig. 5) in the fixed rails 71 with their forward ends covered b the projections m of the fixed rails, in or er that at all times there is preserved a continuity of surface upon which the cans roll. 21 is a stretcher wire extendin across the adjustable portion of the labe guide to which its ends are fastened, from under which the rear end of the upper label is drawn by the rollin can.

eferring to Fig. 5, y is an edge on the fixed bars 1' of the label guide which in all cases is in vertical alinement with the forward edge of the stack of labels, and this edge must always bear a certain relation to the vertical center line of the cement wheels 15. For instance, in the affixing of labels to the largest cans, the distance between these two points will be practically the circumference of the can, in order that the portion of the can to which cement has been applied will roll over, and pick up the forward end of the top label of the stack, and the cement receptacle is therefore adjusted in position to effect that result. When cans of smaller diameter are to be labeled, the said distance must be a multi le of the circumference of the cans thus: f a can to be labeled has a circumference which is onehalf that of the largest can, it would be practically impossible to decrease the distance between the said points one-half, consequently the said receptacle would be kept in its original position, and the cans would merely make two rotations before reaching the point y. But should the original distance not be a multiple of the circumference of the smaller cans, the cement rece tacle would have to be moved longitudina y of the machine to such a distance that a certain number of rotations of the can, the cemented ortion of the can will come into con tact with and pick u the forward end of the label; It must be orne in mind that the upper label of the stack of labels is flush with t e top edge of the longitudinal bars 1, and

by reference to Fig. 5 of the drawing, it will be seen that the edge y of the label guide is below the label, and from near that point, the guide rises to a height which is above the said rails, and this increased height is maintained until the can is about to come into contact with and press upon the pasting belt 24. The object of this construction is tomake the can during the labeling1 opera tion, traverse a reater distance t an the length of the labeF the end of which is drawn from under the wire 21, thus placing sufficient tension on the label to cause it to be wrapped tightly around the can. 22 is a paste pot supported by one of the longitudinal bars 1 of the frame along which it is adapted to be slid, and the means for its attachment to the said bar is of such character as to admit of the adjustment of the paste pot with respect to the adjustable portion of the label guide and particularl to the wire 21. 24 is an endless pasting elt which is carried by a Wheel 18 in the aste pot, and a sheave 25 which is tight on t e shaft 27 (see 75 Fig. 6) but which is moved longitudinally of the said shaft when the paste pot is adjusted, and thereby brought into alinement with the pastewheel.

B reference to the ibwer lay of the pasting belt which applies paste to the label, enters the paste pot near its bottom, and in consequence, ver thin paste cannot be used, as it would leak from the pot. supported by inclined bars 31 ada ted to slide in bosses n formed on the stan ards 33 which support the shaft 34 of the smalle. pulleys 9 v which together'with the larger,

pulleys 7, before referred to, carry the conve er belts 5. The object in making the u leys 9 smaller in diameter than the puleys 7, is to provide for the labeling of cans of various diameters, without vertical adjustment of the standards 33. The conveyer belts at the delivery end of the machine when slightly deflected in a downward direction by pressure thereon of the tension ulleys 30 have such height above the cushloned bed 35 as to exert the desired (pressure on the labels of cans of the largest ameter being labeled. Owing to the inclined osition of the bars 31, and their longitu inal adjustability, a forward movement of the said bars lowers the'tension pulleys 30and the lower lay of the conveyer belts upon which they bear, and thereby causes them to bear on the labels of cans of a smaller diameter. 37 is a roller arranged to bear with a yielding pressure on the lower lay of the block 40 placed loose y on the shaft 34 of the pulleys 9. 36 is a! gravity roller which rests on the lower lay of the endless conveyer belts 5, at a point directly over the forward or entrance end of the label table 19.

In the rapid passage of cans under the roller the same has imparted to it a vertical vibratory movement and practically strikes the belt over each can at the time that its cemented portion comes into contact with the forward end of thelabel, thus causing the label to adhere to the can more fully than if the can were subjected merely to the weight of the roller.

I am aware that it is not new to apply tension rollers to belts, but in my invention 13" Fig. 5 it will be seen that 80 30, 30 are tension pulleys 85 situated in the. 0t and receives its rotation 1 from the said be t; and in order that the resceases is considerably greater than that due to the weight of the descending body.

4 The pasting belt is normally clear of the label, but is pressed down and brought into contact with it by the can. Depressions o I in the adjustable rails is of the label guide receive the pasting belt when forced down by the, can, at the place where the ends of the labels'are lapped. In some cases it is desirable to use very thin paste and as such would leak from the aperture through which shown in Figs. 9 an 10 to which referencethe lower lay of the pasting belt enters the paste pot, I emplo the pasting devices should be made. In the said 'figures, the

i pasting belt 24 does not entervthe paste pot 22 but receives its coating of paste from the' circumference of the rotary disk 41 which is sure of the disk on the belt will be un orm notwithstanding variations in the thickness of the belt, the paste pot ispivoted by m'eans i offlbolts to In s 42 between the brackets 43 which carry t e shaft 45 of the pasting .belt Wheel '47, and is spring-held.

The tension pulleys30 are then adjusted so that the lower lay of the coni 5 veyer'belts will bear properly on the cans to belabeled, and the roller 37 moved forward so as to press down the belt on the'can immediately before the can reaches the pasting -belt."- The cement rece tacle is now-moved fc its cement wheels and the edgev y of the to aposit onwhereint e distance between fixed rails of the label guide will be amultile of. the circumference of the cans. The abel table is-then provided with a stack of labels of the required length which are rear end of the label tobe applied to the can,

and which is susceptible to adjustment with respect to the cement applying devices, and a paste-applying mechanism which is adjustable in position with respect to the movable section of the label guide, combined with a vertically adjustable conveyer belt,
