8 Claims. (Cl- 198-219) This invention relates to a conveyer for general use but adapted for use in conveying bottles or other articles to be labeled through a labeling machine and stopping them intermittently for the various steps required in placing the labels thereon, and wiping them down, and delivering.

The principal objects of the invention are to provide for intermittently conveying the bottles or articles, without necessitating the gripping thereof, thus eliminating considerable mechanism and cost and to provide means for operating a rest, and also a top holder simultaneously, in a rectilinear path so that the bottles or the like will first rest on a support, then be lifted and moved forward, dropped back on the support and the process repeated in reverse, the means for raising the bottles passing down and then back, then up again, thus completing the rectangle.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. l is a side view of a straightaway labeling machine constructed with a conveyer made in accordance with this invention;

Fig. 13 is a similar view showing the bottle in the same position as in dotted lines in Fig. 12, but with the means for holding the top of the 5 bottle raised, so as to release it and the conveying means lowered so that the bottle rests on the stationary tracks, the conveyer and means for holding the bottle at the top being ready to start back as indicated by the arrows. 10

The invention is shown as applied to a labeling machine in which labels are placed on opposite sides of a bottle and wiped down thereon and in which the bottles are conveyed into the machine by an endless conveyer lo and pushed by the 15 pusher ll, transversely on a pair of tracks I! spaced from each other. The bottles are moved in a way that will be described, intermittently to a number of positions or stations, as shown in Fig. 2. Here the labels are placed upon them 20 by the pickers i3 and then pressed down on the opposite sides of the bottles by two sets of wipers I4 and i 5. The bottles are then pushed from the tracks on a discharge conveyer I which carries them away. The invention is not limited 25 to this particular method of labeling or to the labeling of bottles.

The tracks I! are shown as two in number and stationary. The means for moving the bottles along the tracks 12 operates in one orbit of 30 rectangular shape. This means comprises a movable slide I! which is provided with a series of rests ll of rubber or other material. Means is provided for raising this slide l1, together with all these rests, from the position shown in 35 Fig. 5, in which the bottle B is resting on the tracks H, to the position shown in Fig. 6 in which the bottles are lifted from these tracks and are supported by the rests It.

This slide I! in its elevated position is moved 4o forward horizontally, taking the bottles with it and moving them along. One bottle is moved from the position shown in Fig. 2 to the next one and then the slide I'I drops down and descends to the position shown in Fig. 5, leaving the 45 bottle on the tracks I2. The slide I! then moves backward horizontally in its lowered position and lastly is raised vertically to the position shown in Fig. 6.

In this way, it will be seen that the bottles are 50 moved forward intermittently and that the slide l1 moves in a rectangular path. This constitutes a very simple motion and eliminates the gripper claws and the mechanism connected with them for opening and closing them, as well as 55 moving them, thus materially simplifying both the construction and operation.

The bottles are held at the top by a series of caps under springcompression and carried by a slide 2|, which is in the form of a horizontal bar, secured to a vertical bar 22 which moves horizontally with the slide 2| to give these caps the same motion as that of the slide ll. When the bottles are moved forward the tops of the bottles are held by the caps and they are released when the slide l-"I moves below the track. Side guides 51 are employed.

The mechanism for accomplishing these momechanism. This shaft is provided with a bevel gear 26 which, by a similar gear, operates a cross shaft 21. On this cross shaft are three cams 28, 29 and 88. These shafts are supported on the frame 8 and a bracket 8 canied thereby.

The cams all operate rolls on levers and the rolls are kept in contact with the cams by springs, if edge cams are used, as shown. The cam 28 operates a roll 8| on a lever 32 pivoted on the bracket 8 at I and connected by a lever 38 pivotally with the slide I. This cam 28 is so shaped as to provide the necessary motion above described or, if it is desired to change the path of the slide from a rectangular one to some other shape, the cam will be changed accordingly. In a similar way the cam operates a roll 34 which is mounted on a lever 35-pivoted at the same point I as the lever 32. Through a link 36 it operates two sliding cams 31 which actuate two vertical slides 38 by means of rollers 39.- To these slides 38 are connected heads 40 which are secured on the slides 38 adjustably and carry a top rail 43.

The slide 2| is supported through rolls 42 by hangers 4| carried by the top rail 43 supported by the heads 40. On the slide 2| are arranged at intervals vertically the movable caps 2|! pressed downwardly by springs 45 and capable of moving the length of slots 46 carried by sliding pins 41 on each upright 48 to which a cap 20 is attached. The pins project through the slots 48 and limit the motion. These caps are for the purpose of engaging the tops of the bottles to be labeled and conveyed and holding the same down against the rests IS.

The lower slide or conveyer proper I! and the upper slide 2| are raised and lowered from a lever 50 which carries a cam roll 5| operated by the cam 29. A link 52 is pivotally connected with the lever 5|! and with a series of levers 53, each carrying a roll 54. When the levers are swung from the position shown in Fig. 11 to that shown in Fig. 12 the rollers 54 raise the slide I1 and the rests l8 lift the bottles off the stationary tracks l2, as stated. The levers 53 are provided with projections 55 at the top which constitute side guides.

The operation is as follows:

The bottles are fed in by the conveyer l0 parallel with the tracks l2. Each bottle is moved sideways by a pusher I and support H operated by slides 'll The slide rises and lifts the bottle on the rest I 8 up from the track about and the top of the bottle is pressed down by the cap 20 so that the bottle is held firmly between these two parts, but yieldingly. As the slide l1 next moves forward the slide 2| moves with it, of course, to the next station and stops. Now the lower slide l1 drops and the upper slide 2| rises leaving the bottles free and standing sti l on the tracks l2. The slides then move back by the same operation.

The bottles move through the successive positions indicated in Fig. 2, one of the above actions taking place to move the bottle from each sta- 5 tion to the next. When left in the position shown in Fig. 12 the slide moves down and the slide 2| up and then they both move backwardly together and then come toward each other again. The bottle is provided with a label on 10 each side in this case, as indicated in Fig. 2 and I this label is pressed or wiped down by the wipers l4 and I5 and then after that the bottle is discharged by the repeated motion that has been described on the two'endless chains Hi. In this 5 way the device for gripping the bottles and the mechanism associated therewith are entirely eliminated.

Having thus described my invention and the advantages thereof, I do not wish to be limited to 20 the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:-
