patent on a rotaiy labeling machine, filed June 11, 1914, Serial'No. 844,553.

This invention relates to a conveying device capable of general use for the purpose of supplying articles to and taking them from a machine in which operations are performed on them, and especially adapted for feeding bottles to and from a horizontal rotary labeling machine.

Reference is to be had to the ing drawings, in which Figure 1 is a plan of part of a rotary labeling machine having a conveyer construct ed in accordance with this invention;

Fig. 8 is a fragmentary side elevation thereof;

accompaany- Fig. 9 is a plan of a portion thereof-on cal shaft 41.

- equal number of crates a horizontal shaft 44 mounted in bearing brackets on the frame. The connection of the motor with the shaft is controlled by a clutch 45 adapted to be thrown in and out by means of a handle 46. On this shaft- 44 is a bevel pinion 47 operating a downwardly facing bevel gear 48 fixed to a verti- Consequently when the clutch is connected the motor will constantly rotate the shaft. A main rotary table 40 is mounted on the top of the vertical shaft 41 and capable of being turned withthis shaft. The table is located in horizontal position and has a horizontal fiat surface around its circumference for receiving the bottles or other articles.

Near the opposite end of the shaft 44 is a bevel pinion 52 meshin with two pinions 53. These are mounte on two

horizontal shafts

54 and 55 respectively. These shafts are supported by a vertical stand 56 cai'ried a cam groovefor receiving a-plurality of rollers, in this instance three. These rollers are mounted on arms 64 which are pivoted on studs carried-by the head. To these arms are fixed gear segments 66,,each of which is adapted to mesh .with a gear segment 67 fixed to another vert'ical stud also carried by the head.

This gear segment is provided with anarm 68 having a spring-pressed plunger 69 thereon. Also carried by the head are an jaws 70 cotiperating with the plunger 69 for the purpose of holding the bottles. The jaws 70 and arms ,68 project through slots in the cylindrical wall of the head. Each of these jaws 70 is pivoted on I a vertical stud on the head and is adapted to be brought back to a definite position against a rear sto this Way three sets of jaws are provided for taking the bottles from a convenient position and placing them on the rotary table. Each set consists, preferably, of two jaws 70 and one plunger 69. 1

In order to supply the bottles to this feed device an endless conveyer is shown. This surface 71 by a spring 7 2. In

comprises a conveyer frame 74 removably fixed to the base Q2 and supporting an endless belt 75 running over pulleys 76 and supported by rollers 77 carried by the conveyel' frame 74. The belt is provided with tighteners 79 and is operated by gearing from the end of the shaft 44:.

The rollers 77 and the other mechanism controlling the feed belt are mounted directly on the edges of a channel iron 80 which is adapted to rest on the frame 74t'and constitutes part thereof. Consequently the feed device constitutes a mechanism capable of being manufactured and assembled separately from the rest of the machine and having no parts projecting overthe labeling machine proper except the parts necessary for carrying the bottles to it and removing them therefrom. This channel is closed at the ends and is provided with a drain outlet 81 to direct any liquid away from the belt. On this channel iron 80 are vertical guides 82 at each side of the feed belt adapted to guide the bottles andnecessitate their being placed on the belt in such position that the same will carry them along to the rotary feeding arrangement which has just been described. The guide at the side from which the bottles are applied is discontinued for a certain distance, so that the bottles may be placed thereon from that side up against the guide on the other side without any special attention being directed to the position in which they are placed.

F or the purpose of insuring thepresentation of the bottles one at a time to the rotary headv 60 the gear 58 carries a series of cams 83 on the top thereof adapted to engage a roller 83 and operate a rod 84: which is connected with one arm of a bellcranl; 85. The other arm of this bell-crank is provided with a stop 86 and as there are as many cam projections 83 on the gear as there are pairs of jaws on the head 60, and as .they are placed "in 'proper position for that operation, the rod 8 will be lifted and the stop 86 withdrawn once for each operation of a pair of feeding aws. These parts are so tim-edg that this will occur just after a bottle has been fed along by these jaws. F or example, in the position shown in Fig. l the stop 86 has'just been withdrawn and brought back into place to stop the third bottle shown. To assist the feeding of the bottles a fixed plate 87 is. provided projecting out into the guide way overthe belt and adjacent to the head 60. Thus, when a bottle A comes up against this projection it is stopped against further motion forward on the belt. However, on account of the angle of this plate 87 it will be forced over to the opposite side of the carrier where it comes against a flexible stop 88 and is held the position shown in Fig. 2 until positively removed therefrom. When is enmam around by the head 60 it again passes over the belt and on a platform 90, and from this to the rotary table d0. These parts are all in the same plane.

The removal of the bottles from the rotary table 40 is still simpler. The other bevel pinion 53 is mounted on the shaft 54. which by means of a bevel pinion 93 thereon drives a gear 94 on a vertical shaft 95 on the stand 56. This vertical shaft is provided with a rotary head 96 and on studs 97 carried thereby are pivoted a series of bell cranks, each comprising an arm 98 having a roller 99 thereon and two jaws 100.

These jaws project out through slots in the vertical walls of the head. Mounted in fixed position on the stand 56,'but centered with respect to the shaft 95, is a grooved cam 101 in which the rollers 99 operate. The jaws 100 therefore come around in time to engage a bottle on the table 40 as that is rotating and the action of the cam is such that the jaw is then quickened in its motion so as to slide the bottle forward fasterthan the table is moving and move it on the other end of the platform 90, from there over the belt on a fixed platform 102, like the platform. 89, and then on the belt which is in the same plane as the

platforms

90 and 102 and the table 40. While the bottle is passing on the belt the aw 100 is retracted so that it will not come in the way of the bottle and so that it will leave the bottle in position on the belt. These parts and also the parts carried by the head 60 are surrounded by casings 103 also acting as guides.

The bottles, when fed to the fiat part of the table in the manner which has been described, are brought in front of a series of lugs or brackets 108 fixed on the table against which the bottles are adapted to be registered just as soon as they reach the table and by which they are positively carried along. I

We will now describe the operation of the machine as a whole.

The motor 48 being in operation the operator is at liberty to manipulate the starting lever 46 to throw in the clutch -i-5 and start the shafts t1, 4:4, and 100. This results in the first place in rotating the table at a rapid but uniform speed. Bottles 3%. are placed by hand or in any other de way upon the feed belt 75 at the l 1 and as they move up toward tn.

device 60 the stop 86 is operated automati-.

cally to allow one bottle at a time to be engaged by this feeding device. This feeding device as it rotates engages a bottle supported by the belt and located between the

parts

87 and 88 and positively moves it around through more than a half circle as has been described already. This operation is performed positively by the jaws 70, but the bottle is also engaged by the springpressed plunger 69 on the other jaw. The bottle is applied in this manner to the rotating table which rotates at a higher speed in feet per minute than the jaws 70. Consequently the bottle will be carried along by, the tablel lhestud 114 moves around with the table and consequently if it engages the surface ofthe jaw 70 it will onlyswing it in opposition to the spring 72 and do no damage. From this point the bottle which has just been gripped by the bottle grip 116 moves along positively with the table until it is unclamped and then engaged by one of the jaws 100 and moved off the table in the manner which has previously been described.

Although we have illustrated and described only one form of the several features of this invention, we are aware of theEfact that many modifications can be made therein without departing from the scope of the invention as expressed in the claims.
