In the form of Another object of the invention is the provithe invention shown in the drawing andheresion of-spaced paste containers supportedfor inafter described, the labels are lifted by thef35 movement onto the marginal edges of a label, marginal ends, along which the adhesive matethere being means for supplying their label enrial is applied in a manner hereinafter fully gaging surfaces with adhesive material, whereby described.

The frame is pivotally supported at opvide a simple and eicient apparatus of the charposite ends to upright supports I9 and 20 asV by acter referred to which may be operated with bolts 2l, shown clearest in Figure 4. The end I'I great rapidity and which will consistently move of .the vframe has a portion 22 which extends 45 one label only at a time into position for` manual lover the labels and forms a supporting arm for removal and application upon an article. a paste container 23V.

In order to make possible the 50 embodiment thereof. For this purpose I have handling ofvlabels of different lengths, I show` shown one form in the accompanying drawing the arm 24 together with its paste container 25 and forming part of the Vpresent specification. as being adjustable relative to the arm 22fand its I shall now proceed to describe this form in depaste container 23.k The arm 24 is formed with tail, which illustrates the general principles of an inwardly extending portion 26 which is se- 55 I bers.

cured to the front frame member I5 as by bolts 2'I and wing nuts 28. A series of openings 29 in the frame member I5 permits for the adjustability of the arm 24 thereon.

The paste containers 23 and 25 are similar in construction and are open at their top with a plurality of small capillary outlet openings formed in their bottom as shown clearest in Figures 2 and 4. Applicant prefers to use a thick viscous. paste which bleeds or oozes through said outlet openings, forming a coating on the bottom of the paste containers. When the containers are moved into engagement with the marginal,

ends of the uppermost label said label adheres to the adhesive surfaces of the containers and is lifted into a convenient position where it may be manually removed and applied to an article.

The paste containers 23 and 25 are pivotally mounted on their respective supporting arms 22 and 24 in a similar manner, shown clearest in Figure 4. Stub shafts 3l are secured to the paste containers and extend through their supporting arms. They carry wing nuts 32 on their ends with coil spring members 33 interposed between said wing nuts and the supporting arms, whereby the frictional engagement between the paste containers and their supporting arms can be varied through the adjustment of. the wing nuts. Each time a label is removed, the height of the label stack is of course reduced and it will be clear how one end of the paste containers will rst engage the uppermost label. 'Through the frictional pivot heretofore described, the paste containers are permitted to automatically adjust themselves upon the marginal ends of the labels. A plurality of holes 34 are provided in the supporting arms 22 and 24 for making possible the interchanging of paste containers to care for labels of different widths. For purposes of production it is desirable to raise the various sized labels to the same label removing position. This is accomplished by maintaining the forward edge of. the paste containers in the same position regardless of their length.

Paste hoppers 35 and 36 are provided for feeding paste to the respective paste containers 23 and 25, over which they are supported by brackets 3T, secured to the upright supports I9 and 20 by bolts 36. As shown clearest in Figure 2, a sliding valve 39 is provided at the mouth of each hopper for controlling the admittance of paste to said paste containers. A member 40 connecting the upper end of the uprights I9 and 20 is provided with a series of openings 40a corresponding to those in the front member I5 of the pivotally mounted frame, whereby to permit a corresponding adjustment of the hopper 36 with the paste container 25.

Y The means employed by applicant for moving the paste containers into engagement with the label ends, is adapted to be operated by the movement of a labeled container after it has been released by the operator and permitted to roll down the inclined track. A shaft 4I is journaled in bearings 42 mounted-on the table legs I I. One end of the shaft extends through its bearing and carries an arm 43, which is connected with the back member I6 of the pivoted frame through a rod 44 which is pivotally connected to said mem- The opposite end of the shaft 4| carries an inclined arm 45 which extends upwardly between the rails I2 and I3 in the path of the labeled articles, one of which is shown in Figures 1 and 3 as being about to` engage the arm 45. The arm is depressed as the article moves .mounted on the underside of the table It.

over its projecting end, and the paste containers are swung downwardly into engagement with the uppermost label which adheres thereto. After the article has passed over the extended portion of the arm, the paste containers together with the label are raised to label removing position by coil springs 46, which connect the rear member I6 of the pivoted frame to the table, as

shown in Figures 1 and 2. The arm 45 is simulv taneously moved upwardly into the path of. the labeled articles, to be operated by the next container, after the label has been removed from the paste containers and applied thereto. Stops 4l (Figure 1) are provided for limiting the upward movement of the paste containers. As a means of adjustment to balance the apparatus under varying conditions, I provide a turnbuckle 48 between the coil springs 46.

The objection to lifting more than one label at a time is overcome by moving the paste containers away from the label stack in an arc. The supporting frame for the paste containers is pivoted sufliciently above the top of the label stack to cause the containers to swing outwardly as they sta-rt to swing upwardly away from the stack of labels. The top label adhering to the paste containers, is accordingly slid forward slightly relative to the adjacent label therebeneath as shown in Figure 5 and its forward end is-raised tween the two sheets. In order to further facilitate the separation of the uppermost sheet from the adjacent sheet therebeneath, I provide the inner faces of the label guides 49 and particularlythe front one, with roughened or file-like surfaces 50. As the top label is moved forward and upward, its front edge engages and is dragged over the rcughened surface of the front guide as shown in Figure 5, thereby insuring its separation from the next and adjacent label.

Figures 2 and 3 best show the means employed by applicant for automatically releasing one unlabeled can at a time, to permit its movement into label applying position. An arm 5I is secured to the shaft 4I adjacent the arm 45. It is connected through a rod 52, to the vertical arm 53 of an angled member which is pivotally connected as at 54 to a supporting bracket 55 A rst, thereby breaking the vacuum created be- '530 rod 56 is pivotally connected as at 51 to the hori=y zontal arm 58 of the angle member and extends upwardly through a sleeve 59 into the path of the unlabeled containers for normally restraining them from moving down the inclined track into label applying position. number of such unlabeled cans in dotted lines. When the arm I5 is depressed as by the passing of a labeled article over its extended end, it will be clear from the foregoing description now the rod 56 is retracted and an unlabeled con-'- Figure 3 shows a? simultaneously retracted to release an unlabeled" article for rolling movement into label applying position. After the labeled article has passed over the extended end of the arm 45 the paste containers are moved upwardly by the spring members 46 and lift the uppermost label by its ends, which adhere to the bottom of said paste containers. At the same time the pin 56 is moved upwardly to prevent more than the one unlabeled article from moving into label applying position and the arm 45 is raised to normal position. The label is pulled from the undersides of the paste containers by grasping its forward edge and is turned over upon the surface of the unlabeled article which is then rolled down the track and over the arm 45 for releasing the next unlabeled article and picking up a label to be applied thereto in the manner described.
