SPECIFICATION forming part of Iletters ZPatent No. 605,858, dated June 21, 1898.

Applicationfiled May 7,1895. seriunmtratoe. (N model.)

To all whom, it may concern: Be it known that LWILLIAM S. CRAIG, a citizen of the United States, residing at Chicago,

- in the county of Cook and State of Illinois,

have invented a certain new anduseful Improvement in Machines for Labeling Cans, which is fully set forth in the following specification, reference being had to the accom panying drawings, in which Figure 1 is a side elevation of my machine. Fig. 2 is a verticallongitudinal section of the left-hand portion of Fig.1. Fig.' '3 is a plan of the tracks and revolving mechanism shown in section in Fig. 2. Fig. at is a plan of the paste-box at the upper end of the machine. Fig. is avertical longitudinal section of the said paste-box- Fig. ,6 is an enlarged detail elevation of the locking and releasing mechanism at the upper end of the machine. Figs. 7, 8, and 9 are detail views, the last in plan,

.of parts of the said mechanism. Fig. is a longitudinal verticalisection of the labelholder and adjacent devices. Fig. 11 is a vertical cross-section of said label-holder. Fig. 12 is a vertical section of the paste-rollers shown at the left-hand side of Fig. 10. Fig. 13 is a plan of the power-supplying device and rolls near the centerofthe machine.

The object of my invention is to make a machine in which the cans are automatically labeled as they pass through the same.

My invention consists in the mechanisms and combination of mechanisms hereinafter fully described and made the subject-matter of the claims hereof.

In the accompanying drawings, A repre-' sents the mainframe of my machine, which is composed of two side pieces A A supported at a suitable incline upon the'legs O C and 0 0 respectively, of which legs only C and C are shown. The side pieces A and A are held at the desired distance apart by crossrods 0, upon which they are adjustable laterally by'means of screw-threads and nuts or other suitable devices to give them the desired distance apart to receive the cans which are being labeled. On the inside of these side pieces I place tracks B and B upon which the ends of the cans rest'as they roll down the incline in the operation of labeling them.

Near the upper end of my machine I place a paste-box D, adj ustably supported upon uprights D D the said paste-box being provided with a valve mechanism consisting of the tube D plug D and downwardly-projecting part D to operate the said plug upon the passage of the can and permit the outflow of paste through the port in the bottom of the paste-box. Under this paste-box and extending some distance downward between the side pieces A A of the machine I place a flexible pad D, so arranged between the tracks that the can as it rolls along the track will come.

in contact with the pad. The paste-box D is adjusted to such height that when the can is placed on the tracks at the upper end of the machine in rollingdownward it will hit against the part D and raise it sufliciently to allow the paste to pass out of the valve and flow upon the central portion of the outside of the can, and as the can passes the valve it will spread thepaste upon the pad, and

the entireLsurface'of-the can between the tracks-upon which the ends of the can rest becomes covered with thepaste. When the can has passed down over the pad, it drops from the track upon one end of the labels in a box full of labels, as is clearly shown in the case of the can X inFig. 10 of the drawings.

The can is held in this position by a locking deviceconsisting of two arms E E pivoted upon opposite sides of the frame upon the pivot E of a cross-rod E mounted in slots 6 e at the upper ends of said arms E E respectively, the said cross-rod E being retained in a yielding position within said slots by the springs e 6 adjustably mounted in the said slot, and of arms E E pivoted to the upper ends of E E respectively, their remaining ends being connected by a second cross-rod E parallel to but in a different plane from E The arm E is connected with the side piece A of the machine bya connecting-rod E pivoted at one end to the said arm E and at its other end to the said side piece at E is pivoted one'end of the rod F at F. The other end of the said rod F is pivoted to the crank-arm F keyed upon the rock-shaft F which extends across between the tracks of To the lower end of the arm E rigid with G,

. said label-holder.

the machine at a point near the lower end thereof, as shown in Figs. 1 and 2, the said rock-shaft carryin a trip F, which projects upward in the pathway of the cans. Upon a can passing down the track at this point it will depress the trip F and so through the rod F throw the locking device hereinafter described into the position shown in dotted lines in Fig. 6. By this movement the can X is allowed to pass downward, while the cross-rod E", pressing against the can X prevents that can and those behind it from following the can X. The spring F now acts upon the crank-arm F to restore it and through it the locking device to normal position, as shown in fulllines. Thereupon the cans X &e., roll down into the position previously occupied by X, &c., where they are checked and retained by the somewhat yielding resistance of the cross-rod E" until the next unlocking operation of the locking device.

The label-holder consists of a bottom plate G, held in position by side pieces g" g. To this bottom plate is pivoted a follower consisting of a top piece G, two set-screws g g giving the bottom of the label-holder G the proper inclination, and of a post G mounted in a guide-tube G depending from the supports 9 9", the upper end of the said postbeing the lower end being provided with a ratchet upon which operates the pawl An upward tendency is given to the post G bya chain or cord attached to the lower end of said post, passing over a pulley g and the cam or pulley G", to which is attached a weighted lever G, the said cam and weighted lever being pivotally mounted in the depending supports G. The label,- holder is prevented from rising beyond its proper position with reference to the tracks by the stop-roll ll, bearing against the lower end of the top label of the labels G in the A secondary paste-box II is suitably supported adjacent to the lower end of the label-holder, the said paste-box carrying a paste-roll H and a distributingroll 11*, contacting with the stop-roll H.

An adjustable plate ll is mounted upon the downward projection II of the paste-box, the upper edge of the said plate II being caused to press against the roll II by means of the spring 11.. To one end of the stop-roll ll is secured a ratchet-wheel ll. A red I, adjustably pivoted at one end at l to the arm E of the locking mechanism, is forked at its lower end, the two branches I and I of the said fork carrying each a tooth engaging with the ratchet-wheel ll". As the arm E periodically vibrates in the releasing of sueces sive cans, a reciprocating motion is given to the rod I, which is transformed by the fork and ratchet-wheel device shown into a rotary motion from left to right on a part of the stop-roll ll, whereby paste is spread upon the lower end of each label where that label is to overlap its other end when rolled upon the can. The plate II prevents the label from being drawn in between the rolls by the movement of the roller 11.

Upon the sides A A of the frame at a point toward the lower end of the label-holder are mounted two uprights K and K, carrying a shaft K upon which shaft are mounted upon opposite ends thereof the pulleys K and K and between the said pulleys the roller K Motion is imparted to the said shaft by a belt K upon the pulley K". The roller K carries an endless belt K which passes over the roller K", mounted in the slots K of the uprights L L farther down the machine. The pulley K carries a belt K whereby its motion is imparted to the pulley M, later to be described. Pivoted to the uprights K K are the arms K carrying at their end the idle pulley or roller K", which is adapted to press against the lower side of the belt K to insure its contact with the upper surface of the cans as they roll down the machine. A spring K may connect the arm K with the upright K to increase this effect of the idle-pulley K". The motion of this belt is such as to carry the cans in the direction of their travel down the machine, and the effect of the belt is to press against the label and lay it smoothly and evenly upon the can.

The uprights L L, above referred to as carrying the roller K in the slots K are vertically adjustable upon the sides of the frame in order to adapt the height of the belt K to cans of different sizes. To the said uprights L L are pivoted two arms N N, in which is mounted a shaft carrying upon its outer end the pulley U, driven by a belt M which derives its motion from the pulley M, which revolves with the pulley M, driven by the belt K hereinafter referred to. Between the arms N N is mounted the roller N upon the shaft driven by the pulley N. Toward the end of the said arms N N is attached a brush N. A spring may be attached to the arm N and the upright l to support the said arm and the mechanism it bears when there is no can present.

Upon the shaft M are mounted the pulleys M and M, above referred to, the former of which communicates motion to the shaft and so revolves the rollers Diand M, also mounted upon the said shaft near the sides A A 01. the frame and below the ends of the

tracks

13 and 13 respectively, their upper surfaces forming, so to speak, a continuation of the said tracks, which are here interrupted. The said tracks are continued again as the two branches I) Z1 contract toward the center of the path of the cans. Farther down the machine they retake their previous position, at tached to the sides of the framework thereof, as 13 ll.

To the branches Z) Z1 are pivoted the arms 0 0 carrying the stop-rollers o n at their outer end and connected by a cross-rod O, which projects through the slots 0 in the sides of the frame. In the pathway of the cans, underneath the belt K is placed a trip I carried by a rock-shaft P, which bears a crank-arm P at its outer end. This trip is retained in its normal upright position by the spring P attached to the framework and to the crank-arm P crank-arm P with the arm P pivoted at P", the upper end of which arm P is adapted to support the rod 0 and so retain the stop-rolls o 0" in their raised position. A spring 0 conmeets the arm 0 with the side of the frame A The operation of the mechanism last above described is as follows: When a can comes into the position X (shown in Figs. 1 and 2,) it is retained in that position by the stop-rolls .0 0 which are prevented from yielding to the downward tendency of the can by the pivoted arm P bearing against andsupporting the cross-rod O. The can is revolved in this position by the, rollers M M, and the effect of the roller N and the brush N is to press and smooth the label firmly upon the can while it is being revolved. As another can advances down the track underneath the belt K it operates the trip P, by which the end of the arm P is withdrawn from its'position under the cross-rod O. The spring 0 yields as the stoprolls 0' o are depressed by the weight of the can X whereby the said can is released and passes down the track and'out of the machine. The spring 0 immediately raises again the stop-rolls 0 0 to permit the end of the arm P to retake its position as supporting the cross rodO, .which it does by virtue of the action of the spring P The stop-rolls are thus again -in position to retain the next can.

From the above description it is apparent that my machine is simple in its construction and economical in its operation.
