tain nevi7 and useful Improvements in Label-A ing-Machines, of which the following is a statement.

The'present invention relates to labeling,`

machines, in Which the labels are pulled by n a roller oif a reciprocating pile, the said roller having been previously provided with gum. This roller ythen delivers the label to a second roller, on whioh'it lies with the gummed side out and which rolls it onto the article to be labeled.

The present invention in particular re lates to an advantageous construction oi' these rollers for pulling,` the labels from the pile and delivering them to the articles to be labeled.

In the accompanying drawing Figure l is a vertical cross section through the machine. Fig. 2 is an end elevation of the machine. Fig. 3 is a cross section through the rollers and the pile of labels. Fig. 4: is a part view of the rollers. Figs.` 5,v 6 are cross sections through the rollers according to Fig. 3, but in other operative positions.

Beneath the roller which receives its gum from the roller 5 dipping` into the gum vessel l'and the gumming rollers 6. is arranged a slide 9 carrying; the pile of labels 8 and slidably fitted on the rails 7. This slide is reciprocated by means of a cam disk 20 fitted to shaft 30, against which cam disk` bears a .lever 21 on shaft 3l.

To-the shaft 3lv are yalsol fitted two leversl 32, the free ends ofv whichy are coupled by rods 33 with the slide 9.

The pile ofi labels 8 rests on a plate 34, which is carried by the rods 16, which are slidably fitted in guides 35lon1the slide 9.

The lovver ends of the rods 16 carry cross bars 16a. to which springs 28 are attached, the other ends of which are secured to the guides 35. These springs thus tend to force the pile of labels upward against a rail i5, which lies across the pile, and which is secured to the Walls 3 6 connected to the slide 9. The rods 16 are toothed.- and in these i teeth eneaae ninions il. on the shaits il left end of the slide run are arranged fixed stops 13, and at the right end of said run 4are Yarranged fixed stopsv lei having inu'ardly curved upper horns 14 as shown.

The roller 2 fitted to shaft 40 has a segment il which, on the roller revolving, re\ ceives the gum from the roller 6. At the iront edge of this segment there are recesses 42, into which parts Li3 engage, which are adjustably fitted to arms 44. These arms .tre all clamped to a shaft i5 journaled in theroller 2, and .on the one end of which, outside of the roller 2, a lever 46 is fitted, which carries a rollerl 47 and, atits end, a set screw 48. The roller 47 hears against a cam disk i9 rigidly fitted tomtlie body of the machine l, as a spring 50 secured to the lever 46 and the roller 2 respectively tends to pull the lever inward.. llVhen the lever 49 has heen turned as far inward as it Will go, the face ends of 'the parts 43 are at the saine level with the surface of the segment all over with gum. Over the roller-2 a roller 54 is journaled on a shaft 55 in the body oi the machine l. The shafts 40 and 55 carry gears 3 oiI equal size, meshingl with each other. at the same speed but in opposite directions,

the segment 4l and the segment 56 `on the.

roller 54 rollingwof on each other.

in front of the front edge ot' the segment i6 double-armed levers 53 are fitted loose on a shaft 57 journaled in roller 54. said levers beine; arranged at the same pitch as the recesses in roller 2.. To the radiallv proiectineT ends of these levers 58 are hinged arms 59 which carrv at their one end thin tongues 60, and at the other ends hold springs 61. secured to the arms 62, which are litted to the hubs of the levers The hubs oif these levers 58 carry noses 63. against which the arms 59 are drawn byy means of the springs 6l. The hubs of the levers 5S have` furthermore. slots 64, into which pins 65 engage, which are secured to shaft 57. The arms of lever 58. proiecting inward are coupled by springs 66 with the roller namelv with the block 67 servingr as counterpoise to the segment 56. On the `Both rollers are therefore revolved- IOS one end of the shaft 57 is fitted a lever 68, which carries a roller 69, which is pulled by a spring 70 fitted to the lever and the roller respectively against a cam disk 71 fitted to the body of the machine.

f Over the roller 54is arranged a table 72, 'on which the articles to be labeled are piled. Un this table is provided a slide 74 with a nose 75, which will, in known manner, push forward the lowermost of.the articles 7 3 when the slide reciprocates. The slide 7 4 is coupled by means of rods 76 with levers 77,

pivoted to the body of. the machine and most sheet of paper plac bearing with rollers ,7 8 against two cam disks 7 9 of equal shape on the shaft 40.

llihen, as shown in Fig. 1, the pile 8 lies Withits front edge directly under the front edge of the segment 4l, the slide 9 will be moved to the right by the cam disk 20 at a speed which is equal to the circumferential velocity of the roller 2. As the pile 8 is at the same ltime pressed by the springs 28 upward and against the segment 41, the upperitill adhere to the, seg- 5 this travel of slide 9 is 14 on stops 14 will .th of ratchet wheelslO, s, and thus lower table `ons il and racks 16. operation has taken stops 14a levers 12 of pawls 12,l and thus the pawls against the teeth of wheels 10, so that in this way the table is sustained in its lowered position. ,The slide 9 now remains stationary until the sheet of paper, has been. completely pulled off the pile 8 and the segment 41 has ment. Shortly be'` is completed, the engage the lower so as to turn the 34, by means o Directly after .t

. passed it. Then the slide 9 with the pile is again moved to the left,. and shortly before the end of thismovement the levers 12 of pawls 12". strike against fixed abutments 18, which swing the pawls od the teeth of the ratchet Wheels, so that the racks 16 and the pile 8 will be raised by the springs 28 so far, that the pile is again pressed against the rail 15. Then the process repeats afresh.

The label hanging to the segment 41 is in the meanwhile pressed on tightly by the rotation of roller 2 and gummed all over. Shortly before the front edge of this segment has reached its highest position, 'the cam disk 49.1ocks thelever 46 toward outside. Thereby the shaft 45 is turned in such a manner, that the parts 43 r'ock toward inside, and the recesses 42 are open (Fig. 4.). Assoon as, now, the two front edges of the segments 41 and.56 touch each other, the cam disk 71y and the spring 70 cause the lever 68 to rock toward inside. Thereby the shaft 57 is turned in such a manner, that the springs 66 can ull the inner ends of the levers 58 towarinside. The tongues 60 Will then also move from the position according to Fig. 3 into the position according to Fig. 5, so that they ,dlawnby means of the slide 74 from the- .upper pile and pushed over the roller 54, so

that the front edge of the label sticks to the article. .Then the cam disk 71 causes the lever 68 to rock toward outside, whereby the shaft 57 is turned. The pins 65 therewith dog the levers 58 so that their arms extending radially toward outside are moved forward in the direction of the rotation of the roller 54. The tongues 60 arev thus drawn out in a tangential direction between the article and the label, as the arms 52 move by such stroke of the levers 58 in such a manner, that the springsGl are stretched (Fig. 6.) Now the roller 80 bearing on roller 54 and driven at the. same circumferential velocity, but in an opposite direction to roller 54 presses the article tightly against the label and by its rota" tion pulls the article.completel v from the pile. By their further revolution, the rollers 54 and 8O then roll the label together with the article between themselves. so that the former sticks to the latter. When the tongues 60 reach their highest position, the partc 43 having' receded from the recesses reach their lowest lposition and a fresh operation is commenced.

.By the employment of the parts 43 it is obtained, that also those parts of the label, which come to lie on the recesses 42 for the entrance of the tongues 60, are gummcd.
