To' all whom it may concern at Leeds, in the county of York, England, have. invented a certain new or Improved Labeling and Wrapping Machine, of which the following is a s ecification.

This invention re ates to a new or improved machine, as hereinafter described, primarily intended for wrappin and affixing labels around rectangular tab ets, said machine being also applicable for wrap ing rectangular bodies, such as chocolate ta lets, in a coverin material, such as tin-foil.

he machine consists, essentially, of a tray adapted togieliver a length or strip of labels to a pair of feed-rollers which deliver the strip in an upstanding position into a pocket, a horizontal knife working through a slot or gap in the said pocket for severin or subdividing the labels, a traveling belt or feeding the tablets up against a fixed stop, a pusher for carrying the first tablet and the subdivided label through an opening formed in the ocket so as to wrap the upper portion of the label around the forward end of the tablet a'ndleave the lower portion of the label,

which is then gummed, depending within the pocketitself, a gripper adapted to receive the partially-labeled tablet and carry it downward with the rear edge of the tablet and its label" against a stationary curved plate to partially bring the rear portion of the label around the rear end of the tablet, and means for completely turning down the rear portion of the label over the tablet and causing the two portions of the label to adhere together; Figure 1 is a side elevation. Fig. 2 is a plan.

Fig. 3 is a sectional side elevation taken on' the line A B of Fig. 2. Fig. 4 is a sectional plan taken on the line C l) of Fig. 3, and Fig.

' 5 is a front elevation of a tablet-labeling ma- 1 around the tab chine constructed in accordance with my infor treating two tablets simultaneously,

which machine consists of two side frames 1,

held together at a suitable distance apart by I means of stay-rods 2, the frames 1 being formed having their u per members 1 situated at an angle or s oping from the back downward and terminating in acu rve with their front vertical members. upper slopin members 1 of the frames 1 are provided inc i'ned cross-stays 3, on which is lengths or strips oflabels. The tray 1, whii-his provided with a hinged cli 4 and guides 4 movement is given to the sloping tray, 4 at the required times by an engaging arm 6, pivoted on a transverse rod 7, through the medium of a runner 8 on the said arm 6, and a time-cam 9 located on a transverse shaft 10, which shaft 10 is driven by s )ur-gearing 11, transverse shaft 12 bcve 'gearing 13, vertical shaft 14, bevelkgearing 15, longitudinal shaft 16, and bevel-gearing 17, from a main shaft 18, provided with a drivingulley 19.

In front of the tray 4 an secured to the frames 1 is a curved guide-plate 20, and at the base of the guide-plate 20 are situated feed-rollers 21 22, the roller 21 being intermittently driven at a suitable speed by spurgearing 23 from the transverse shaft 12, while ,the rollers 22 are set up to the roller 21 by a driven by frictionj Belowthe feed-rollers 21 22 are two vertically-arranged receptacles or pockets 25, across which is formed a transverse slot or gap 26, through which a horizontal knife 27, pivoted at 28, is free to work the medium of a link 29 and a lever 30, pivoted on a stud 30 so as to'be operated in one direction by a spring 31 and inthe opposite direction by a cam 32, located'on the transverse shaft 12, while at a suitable distance below the knife 27 the pockets 25 are divided by transverse openings 33, and immediately in front of these openings 33 and transversely across the front of the machine is an endless traveling belt 34, adapted to feed the tablets up to a stop 35, which belt 34 issupported by a stationary tray 36 and carried by a pulley 37, which is driven from the vertical shaft 14 by 'bevel-gearing 38, longitudinal shaft 39, pulley 40, cord 41, and pulley 42.

mounted a tray- 4 for the reception ofthe Between the or the strips, is situated etween guides 5, located on the stays 3 so as tobe capable of a sliding movement on the latter, which sliding spring-plunger arrangement 24, so as to be intermittently at the required times through Between the side frames 1 and at the back ble gripper 43, which is carried by a series of pivoted levers 44, 45, 46, and 47, forming a.

parallelogram, the upper end of the lever 45, which is pivoted on the transverse rod 7, being provided with a runner 48, engaging a cam 49, situated on the main shaft 18, and being provided with a spring 50 for keeping the runner 48 in contact with the said cam 49, while the lever 47, which is pivoted on a transverse rod 51, is provided with a runner 52, engaging a cam 53, situatedon a trans verse auxiliary shaft 54, which latter is driven from the longitudinal shaft 3.) by bevel-gearing 55. On the auxiliary shaft 54 is mounted another cam 56, engaging a runner 57 of a rocking arm 58, pivoted on a stud 59, the free end of which arm 58 is connected, by means of a rod 60, to an arm 61 of a double lever 62, pivoted on a transverse rod 63, which levers 62 carry a double pusher 64, which is located immediately in front of the traveling belt 34 in a position directly opposite the openings 33 formed in the pockets 25, and the arm 61 is ')rovide( l with a spring 65 for keeping the runner 57 of the arm 58 in contact with the cam 56, while on the rod 63 are pivoted two arms 66, carrying a pair of rollers 67, adapted to run on a gumming-pad 68, located immediatel' in front of the lower or open parts 25 of the pockets 25. ()n the inner side of the pockets 25, below the openings 33, is located an in\vardlv-curved plate 69, and near the bottom edge of the. plate 69 a trough-like channel or conductor-spoitt 70 is provided, having a pair of inner guide-rails 71, over which a pair of stationary brushes 72 are mounted, while in between the guiderails 71 are a pairol' endless chains 73, mount ed on wheels 74 75, carried on transverse shafts 76 77, which chains 73, formed with teeth 78 at intervals in their length, are driven from the auxiliary shaft 54 b v a chain 7%). The clmin-shaft 77 is provided with a cam 80, engaging a runner 81 on one-of the arms 66, carrying the gu'mming-rollers 67.

in action the machine works as follows: Two lengths or st rips of labels 82 having been placed in the tray 4 beneath the hinged clip 4", as shown in broken lines at Fig. 2, the said tray 4 is slid downward on the inclined cross-stays 3 by reason of the rotating (am 9 allowing the tray-engaging arm 6 to rock forard, whereby the strips 82am thuscaused to slide downward over the guide-plate 2t) and engage between the rotating feed-rollers 21 22, which then deliver the said strips 82 in an upstanding position into the vertical pockets 25, when the horizontal knife 27 is operated, through the medium of the rotating cam 32, level-3t), and link 2t), so 'as to pass through the transverse slot or gap 26 and sever the strips s2, 'lhe subdivided labels 82 are now held in a vertical position loythe pockets 25 themselves, and simultaneously with these movements the tablets 83 are fed forward by the traveling belt 34, so that the first tablet 83 rests against the stop 35, with the first and third tablets directly opposite the transverse openings 33, formed in the pockets 25, as shown in broken lines at Fig. 4. The pusher 64 now moves inward by reason of the rotating cam 56 operating the rocking arm 58, red 60, arm 6]., and levers 62, so as to move the tablets 83 forward against the upstanding labels 82 (see Fig. 6) and then carry the tablets 83 and their labels 82 through the trans- 'Verse openings 33 inthe pockets 25, so that the upper portions of the labels 82 are wrapped around the forward ends of the tablets 83 and leave a portion of the lower ends of the said labels 82 depending within the pockets 25, (See Fig. 7.) During the time the tablets 83 are being pushed, with their labels 82, through the openings 33 in the pockets 25 the gumming-r0llers 67 are moved inward by reason of the rotating cam engaging the arms 66, so that the said rollers 67 engage against the lower portions of the-labels 82as they are drawn upward and apply a suitable quantity of adhesive substance to the lower portions of the said labels 82, while the'gripper 43, which during these operations is held in a forward position, (see Fig. 3,) receives the partially-labeled tablets. The rotating cam 49 then allows the parallelogram of levers to rock outward and recede the gripper 43, which latter draws ,the partially-labeled tablets entirely through the openings 33,

formed in the pockets 25, when the said partiall vlabeled tablets are carried downward with the. gripper 43 through the medium of' the rotating cams 49 and 53 operating the pivoted levers 44, 45-, 46, and 47,;forming the parallelogram, so that the rear edges of the tablets 83 and their labels82 sw xp down the curved plate 69, which has the effect of partially bringing the rear portions of the labels -82 around the rear ends of the tablets 83. (See Fig. 8.) When the tablets 83 and their labels 82 have been carried down below the" curved plate 69, the operating-cam 49 of the parallelogram carries the gripper 43 forward, which brings the rear edges of the'partiallylabeled tablets between the guiderails 71. and the brushes 72, when the teeth 78 of the traveling chains 73 carry the tablets and their wrappers down the said guide-rails 71 and beneath the brushes 72, which turn down the rear portions of the labels 82 over the tablets 83, and at the. same time cause the two portions of each label to adhere together, (see Fig. 9,) in which condition the labeled tablets pass away down the conductor-spout 70.

and their labels to the pressing-brushes 72 the said gripper 43 is moved back to its nor- I 2 5 After the gripper 43 has delivered the tablets seat is mal position through the medium of the operating-cams 49 53 and the parallelogram, ready to receive the next two tablets and their labels, when the above-described cycle of operations is repeated for every two tab lets, which tablets are passed through the machine in nick successlon.

' in emp oying the above-described machine for wrapping tablets in tin-foil the mming device is dispensed with, while the wrappers, which are of-such a width as to overlap the ends of the tablets, are folded over the sides of the tablets in the manner and by the mechanism hereinbefore described with reference to the folding of the labels over the ends ofthe tablets, the ends of the wrappers being afterward turned down and under the tablets by means of brushes and plow-blades located 'in the conductor-spout 7 O.
