My present invention relates to labeling ma chines and more particularly to a labeling machine having a minimum of parts and a relatively light, open frame that permits the operator to closely watch every phase of the operation of the machine. This application is an improvement upon the machine shown. and described in my pending application for patent Serial No. 131,273, filed March 1'7, 1937, to which reference is made for subject matter shown but not claimed herein. An important object of my invention is to provide a machine for the mechanical labeling of containers wherein the cost of manufacture is greatly reduced by the use of a light rectangular frame and the use of simple swinging parts. The use of costly cams andassociated parts is held to a minimum in my machine. A further object is to provide a holder for labels that is normally out of reach of the picker bars, to avoid having to stop the machine when the supply of containers is temporarily exhausted. 7 Another object is to provide an adhesive transfer roll that is held in uniformly close contact with the picker bars during the adhesive transfer period. My improved machine provides other objects and advantages due to the novel combinations and arrangements of parts that will be more fully apparent in the course of the following description. In the drawings, like reference characters designate similar parts in the several views. Figure l is a vertical section on the line I--I of Figure 3. Figure 2 is a front elevation of the machine taken from the left of Figure l. I Figure 3 is a horizontal section taken on the line 3-3 of Figure 1. Figure 4 is a detail perspective view of a latch that holds the adhesive transfer roll in the position shown in Figure 1. Figure 5 is a side elevation of themachine with parts broken away. Figure 6 is a vertical section on the line 6-6 of Figure 3. v Figure 7 is a vertical section on the line l'l of Figure 1. Figure 8 is a horizontal section on the line 8-8 of Figure .5; Figure 9 is a fragmentary vertical section on the line 99 of Figure 3. Figure 10 is a side elevation, partly bro-ken away, of a grip finger that holds the'label against the container. Figure 11 is a section on the line H--H of Figure 10. Figure l2isa vertical section taken on the line IZ-lZ of Figure 3. Figure 13 is a side elevation of the parts shown in Figure 12, looking in the direction of the arrow A of the latter figure. Figure 14 is a sectional View on the line hl-i4 of Figure 13. Figure 15 is a horizontal section taken through ence number I generally designates an open rectangular frame made, in the preferred embodiment, of channeliron and comprising vertical corner members 2, 3, 6 and 5, the same being connected by transverse bars 6 and l and tie rods 8, 9, ill, H and i2. i A channel bar it extends between corner members 2 and 4 as in Figures 1, 2 and 9. The channel I3 is perforated to receive rods 54, (see Figure 9), said rods being connected at their upper ends to a bottle supporting plate l5, spaced above the channel by spacers iii. A strap l1 extends across the rods M to hold the same in fixed position, after the rods have been ad justed to support plate H5 at the desired height. A bolt and nut, l8 and I9, fasten strap I! to channel 13. A pair of spaced rods 20 and 2|, extend upwardly from plate IE to hold the bottle Bin labeling position, as in Figure 3; The rods. 26 and 2| are provided with protecting'sleeves 132 and 23, of rubber or othersuitable materiaLto protect the bottle and at the same time leave its surface uncovered sufficiently for the label to be applied. A label holder 24- is pivotally supported upon 7 transverse shaft 25 by bearing 26 The label holder (see Figures 1 andl'l), comprises a rectangular frame having a transverse bar 21 and angle iron support 28. The label holder is yieldably supported upon the frame members 6 by means of coil springs 29 and 36, positioned as shown in Figure 17. Bar .21 and support 28 are connected adjacent their free ends by' rods 3! and 32, said rods having their ends threaded to receive nuts 33. The space thus provided is divided by transverse rods 34 having clamps 35 adjustably connected to rods SI and 32, and longitudinal rods 36 adjustably fastened to rods 64. Upright angle strips 3'1 are adjustably fastened to the rods 36 and 34 by means of clamps 38. The label holder 24 is pivotally supported upon bar I by means of an arm 39, pivoted to angle iron 28 at 40, said arm having a slot M to receive the bar I0. The arm 39 is in turn pivotally connected to a depending rod 42 which is releasably connected to a foot pedal (not shown). Thus it is seen that springs 29 and 39 normally hold the labels L out of reach of picker bars until the foot pedal is operated, making it unnecessary to stop the machine when a new supply of labels is being placed in position. The lowermost ends of angle strips 31 are turned in as at 43 to support labels L, and the usual weight 44 is placed upon the same. The modified form of label holder 24' provides an extra compartment 44 for neck labels L, by the addition of rods 34' and strips 3? on the rod 34' and on the adjacent rod 34. Otherwise the form shown in Figure 1'7 is similar to the first described form. Means are provided to remove the lowermost label from the label holder 24, (see Figure 9), the transfer the same to bottle B, by the use of picker bars 45, provided with adjustable glue plates 46, and pivotally mounted on shaft 25. Fixed to shaft 25, between the picker bars and the frame parallel to the said bars, are cam bars 41 provided at their free ends with cams 48 for a purpose to be later described. The glue plates 46 are supplied with glue by means of glue transfer roll, 49 carried freely on shaft 50, which is mounted on the free ends of swinging arms said arms are mounted on a shaft 55 which is journalled in bearings 52 above the frame member 6. Shaft 50 is also provided with cam rollers 53 mounted in alinement with cams 48 and adapted, as in Figure 9, to engage the same when a label is being removed from the label holder 24. The transfer roll 49 is held in the position shown in Figure l by means of latches 54 pivotally connected to frame members 3 and 5, and actuated by means to he later described. Aglue pot or glue fountain I55 is mounted between frame members 9 and 5 by means of bearings 56 and 5'? in which the shaft 58 is freely mounted. A glue pot roller 59 is mounted on shaft 58, and within glue pot I55, at a point opposite and somewhat higher than the bottle stand I5. A sprocket BI is fixed to one end of shaft 53 and a clutch 62 is provided between roller 59 and the sprocket 6|. A brace I63 is mounted on bar II, aids in supporting the glue pot holder I64 which is provided with adjustable bolts I95. A hinged scraper plate I06 is mounted on the glue pot as shown in Figure 9. In order to hold the label against the bottle after the picker bars have moved away from same, a grip finger 63 (see Figures 9, 10, 11 and 15) is provided. The grip finger is freely mounted on shaft 64 by means of strap 65 which is given a quarter turn to provide a guide bar for holder plates 69 which are turned in as at 6'! to provide a dove-tail groove for a strip 68, which is made of rubber or other suitable material. A spacer bar 69 is riveted between plates 66 and coil springs 79 are set into alined recesses in bar 69 and strap 65. The plates 66 are yieldably connected to straps 65 by means of rivets II extending into slots "I2 of plates 66. Thus it may be seen that strip 68 is yieldably mounted on strap 65. The strap 65 has a bracket lug 13 pivotally connected to link I4 which is yieldably connected by coil spring I5 to an arm 16 which is fixed to a rocker shaft I7. As shown in Figure 15, padded fingers I8 are utilized to press the label against the bottle. The pressing fingers I8 swing on opposite sides of the grip finger 63, and are preferably made of sponge rubber or the like. The sponge rubber pads of the fingers I8 are carried by box-like holders I9 which are yieldably connected by springs 80 and guide pins BI to straps 82. Straps 82 are freely mounted on shaft 64, and are provided with depending lugs 89 which are pivotally connected to links 84. The links 34 are pivotally connected to arms 85 which are fixed to rock shaft 06. The grip finger 63 is locked in its raised position (see Figures and by means of a latch comprising a pawl 87, fixed to shaft TI and adapted to engage a pivoted arm 88. The arm 88, which is pivoted on frame member 4, is notched as at 89 and held against the pawl 01 by spring 90, carried by a bearing 9I also on the frame member 4. The arm 88 is released when engaged by pin 92, carried by a link 93, which is fixed to a shaft 86. In order to operate the pressing fingers 78 at the proper time, a cam 94, (see Figure 7) is freely mounted on a shaft 95, which is supported by frame bars I. A cam roller 96 is carried by an adjustable arm 9'! on a clamp 98, which is fixed to shaft 86. The cam 94 is provided with an integral sleeve 99 having formed thereon a sprocket 00. The cam shaft 95 is provided at one end with a small sprocket MI and at its other end with a large sprocket I02. My improved machine is driven by a motor I93, supported by arms I94 fixed to tie rod 9, as in Figure 5. Mounted on frame bar I is a shaft I05 provided with a large sheave I09 adapted to be driven from motor I03 by belt I91 at a reduced rate of speed. The shaft I05 is provided at one end with a small sprocket I08, see Figure 6, so that a chain I09 may be utilized to drive sprocket I92 and drive shaft 58 through the intermediary of sprocket 6|. The cam sprocket I00 is connected by chain II 0 to drive sprocket III on shaft 64. Means for releasing latches 54, see Figure 6, is provided by awalking beam I I2 fixedly mounted on shaft 25. One end of the walking beam is pivoted to an arm H3, which is provided with a lost motion slot II4, adapted to receive bolt H5 of a crank I6, fixed to shaft TI. Fixed to shaft 64 is a crank H! which is pivotally connected to the free end of walking beam I I2 by a pitman I I8. Short shafts I I9 are mounted on the under side of frame bars 6, adjacent the latches 54, and fixedly support a rocker comprising lugs I20. The lugs have perforated extensions to receive rods I2I which extend through perforations I54 in latches 54, and plates I22 which are perforated to slidably receive rod I23. Rod I23 is pivoted to lug I24 of the walking beam I I2 and has an adjustable stop I 25 adapted to contact one of the lugs I in order to release latches 54 by rockingthe lugs I20, thereby lifting rods I2I. The sprocket IIlI on shaft 95 is connected by chain I26 to large sprocket I2! on shaft 64. In the operation of my device, the' bottle B or other container is placed upon the stand l5 and held against uprights 22 and 23, leaving an exposed surface between the same. As shown in Figure 1, the picker bars 15 having just picked a label and'have moved into operative position adjacent the bottle. The picker bars are swung from the position shown in Figure "1 tothat shown in full lines in Figure 9 by the rockingof shaft 25, which is fixed to walking beam H2, the same being actuated by the pitman H8 and crank I IT. The crank H7 is rotated by shaft M, driven by sprocket I27 and chain 126 from shaft 85. The shaft 95, see Figure 6, carries sprocket 592, which through chain IE9 is driven from shaft Hi5, and said shaft, see Figure 5, is'driven from motor its by reason of the belt fill that connects the motor pulley and sheave 565 on the shaft The next step in the operation, see Figure 1, is to move the grip finger strip 58, see Figure 15, into contact with the label, to hold the same against the bottle. This is done by the rocking of the walking beam 112, which raises arms H3 and M6 to rock shaft Tl in counter-clockwise direction to swing the grip finger 68 into theposition of Figure 15. In this position, the grip finger shaft 11 is locked by pawl 81 and latch 88; see Figures 12, 13 and 14. The next step is to move pressing fingers 78, see Figure 15, into contact with the label .to press the latter against the bottle until the glue adheres. Cam 94 carries an integral sprocket 109 which is driven by chain In, see Figure 6, from shaft M. Rotation'of cam 94 will actuate roller 96 on arm 9? and rock shaft 85, causing the pressing fingers T8 to be moved against the label as in Figure 15. The mechanism is so timed that the picker arms 52 swing away from the bottle just after the grip finger 63 has grippedthe label, so as to make room for the pressing fingers. A coil spring 83 connects arm 82 of thefingers 18 so that when the pin 92, of Figures 12 and 14, moves against latch 88 to release the grip finger, the same will be cushioned by spring 83'. At this time the cam will allow roller96 to drop so that the grip finger and the pressing fingers will retract together and the latch 88 will again be locked. v ' As the picker arms begin to swing back to the label holder 25, it is desired to provide their face plates 53 with another coating of glue. To1effect this, it is necessary to release glue transfer roll 3.9 from latches 56, as in Figures 1 and 6. The rod-123 being connected to beam H2, it is apparent that stop i25 will contact lug to rock shaft H9 and lift rod 121. This action will raise latches 54 and releasethe glue transfer roll 48, which will swing down into contact with plates 5%, by reason of the energy stored up in spring 128, see Figure 5, fixed to the frame at i233 and to arm.l3t of shaft 55. This movement is dampened by a dash-pot mechanism, as follows: at an intermediate'point the rod i3! is pivoted to arm H30 and extends into cylinder I32 where it is provided with a piston 133. A valve 534 acts as a bleeder. V 7 Thus it may be seen that the glue transfer roller 49 is held against plates 45 with a steady, uniform pressure while the glue is being transferred. Theglue roller 59 is rotated continuously by sprocket iii and chain 169,, see Figure 6. While I have described a preferred embodimiliar with the art that numerous changes and modifications may be made to adapt the machine to various sizes and shapes of bottlesor other containers to be labeled.
