  • the hopper 9 is provided with a bottom it which is inclined, as indicated in Figure 1, from adjacent the outer end of the hopper downwardly toward the inner end thereof so that the sticks contained in the hopper will gravitate forwardly toward the inner end of the hopper.
  • a feed drum [2 which, as shown more particularly in Figures 1, 2 and 14, is mounted upon a shaft [3 journaled in suitable bearing members M which are secured to the center post 4.
  • drum [2 and shaft [3 are continuously rotated by a suitable motor l5 mounted on a bracket [6 secured to one of the side rails 6 adjacent the posts 3.
  • the motor I5 is connected with a drive shaft I 8 by means of a belt 19 and a pair of pulleys 2! and 2! connected with the shaft of the motor i5 and the drive shaft l8, respectively.
  • the drive shaft I8 is journaled in a pair of bearings 23 secured to auxiliary side rails 24 of the frame I which extend between the end posts 3 and the center posts 4 in a plane above the side rails 1.
  • the drive shaft !8 is arranged in substantially parallel relation with the drum shaft l3 and is operatively connected with said drum shaft by a pinion gear 25 secured to one end of the shaft [8 in meshing engagement with a spur gear 26 secured to the drum shaft I3, as illustrated in Figure 2.

  • the selector roll 38 is arranged to operate in close relation with the periphery of the feed drum l2 so that sticks contained in the hopper 9 may not pass between the selector roll and the periphery of the feed drum I2 unless said sticks are substantially wholly contained within the recesses 36.
  • the stick will then be moved by the remaining sticks in the hopper, which are maintained in a state of agitation by the feed drum, along the baffle plate 36 toward the upper end thereof and will eventually appear at the upper side of the mass o'fsitcks contained in the hopper 9 so that an attendant may observe such irregular or Warped stick and remove it from the hopper.

  • the shaft 48 is intermittently rocked in synchronism with the registration of successive recesses 36 with the fingers 45 by means of an eccentric 52 secured to the drive shaft I6 inter mediate the pinion 25 and the bearing member 23 adjacent thereto, as illustrated in Figure 3.
  • An eccentric rod 53 which is connected with the eccentric 52 by an eccentric strap 54, is pivotally connected, as at 55, with one end of the rock arm 56 which has the other end thereof mounted upon the rock shaft 48, as shown in Figures 3 and 4.
  • the arm 56 is secured to the rock shaft 48 so that rocking movement of said arm produced by the eccentric 52 and eccentric rod 53 will produce a sufficient rocking movement of the shaft 48 and bracket 41 during each revolution of the drive shaft l6 to actuate the fingers 45.
  • the relation of the pinion 25 and gear 26 with respect toeach other and to the spacings of adjacent recesses 36 is such that the drive shaft l8 will be rotated one revolution as the feed drum l2 moves circumferentially a distance equal to the distance between two adjacent recesses 36.

It therefore follows that during each revolution of the drive shaft IS the feed arms 46 and fingers 45 associated therewith will complete one vertical cycle of movement and the position of the eccentric 52 on the shaft 18 is such that the upward movement of the arms'46 and fingers 45 will begin as each successive recess. 36 comes into registration with the lower end of the magazine 32. f
  • the grooves or recesses 56 in the periphery of the feed drum l2 are of such a depth that the fingers 45, when in their lowermost position, normally lie beneath the bottoms of the recesses 36 registering with the magazine 32 so that as the recessescome intoiregistration with said magazine'the sticks carried therein will be moved'over said fingers into position to be lifted out of the recesses during the upward movement of the fingers.

13 Claims.
This invention relates to a machine for assorting sticks or other articles of uniform shape and size and wrapping them into bundles.
The main object of the invention is to provide a machine of the above mentioned class that is simple, economical and durable in construction and which is accurate and rapid in operation.
A more specific object of the invention is to provide a machine for wrapping wooden sticks such, for example, as used in connection with ice cream paddles or other frozen confections, with a, feed means for successively moving the sticks into a bundle magazine which includes an automatic selector means adapted to reject unusable warped or twisted sticks.
Another object of the invention resides in providing a wrapping machine of the above mentioned class with a counting mechanism associated with the feed means for stacking the sticks which only counts sticks that are of predetermined substantially uniform length so that sticks entering the stacks which are under the prescribed or predetermined length but may be straight and otherwise usable will be in excess of the specified quota, and all of the stacks or bundles will contain an equal number of full length usable sticks.
A further object of the invention is to provide a wrapping machine which will secure the sticks of a bundle'tightly together whether the number of sticks in the bundle equals or exceeds a predetermined amount.
In carrying out the above mentioned objects, the sticks are first collected one upon another in stacks containing a predetermined number of full length usable sticks, after which the sticks of each stack are tightly wrapped in a suitable wrapper or label with the ends of said wrapper or label glued together in overlapping relation.
A still further object of the invention is to provide a wrapping mechanism and a gluing device adapted to cooperate for so applying glue or other adhesive to the label and folding said label that the glue or adhesive will not come into contact with the sticks of the bundle whereby said sticks will be maintained in a clean, sanitary condition ready for use.
Other objects and advantages pertaining to the construction of my novel wrapping machine and to the form and relation of the parts thereof will more readily appear from the following description taken in conjunction with the accompanying drawings, in which:

Figure 26 is a perspective view of one of the sticks which the machine illustrated in the drawings is particularly adapted to form in bundles.
Figure 27 is a perspective view of a bundle of sticks with the label or wrapper applied thereto.
The machine, as illustrated more particularly in Figure l of the drawings, comprises a frame I composed of end posts 2 and 2 arranged at one end and two posts 3 arranged at the other end of the frame, a pair of center posts 4 and top,
bottom and intermediate side rails 5, 6 and 1,
respectively, which connect the end and center posts 2, 2, 3 and 4 to each other.
Positioned between the end posts 2 and 2' and the center post 4 is a hopper 9 for receiving the sticks, as S (Figure 26), to be wrapped. The width of the hopper 9 is slightl greater than the length of the sticks S for receiving the sticks transversely thereof. The hopper 9 is provided with a bottom it which is inclined, as indicated in Figure 1, from adjacent the outer end of the hopper downwardly toward the inner end thereof so that the sticks contained in the hopper will gravitate forwardly toward the inner end of the hopper.
Registering with th inner end of the hopper 9 is a feed drum [2 which, as shown more particularly in Figures 1, 2 and 14, is mounted upon a shaft [3 journaled in suitable bearing members M which are secured to the center post 4. The
drum [2 and shaft [3 are continuously rotated by a suitable motor l5 mounted on a bracket [6 secured to one of the side rails 6 adjacent the posts 3. The motor I5 is connected with a drive shaft I 8 by means of a belt 19 and a pair of pulleys 2!! and 2! connected with the shaft of the motor i5 and the drive shaft l8, respectively. The drive shaft I8 is journaled in a pair of bearings 23 secured to auxiliary side rails 24 of the frame I which extend between the end posts 3 and the center posts 4 in a plane above the side rails 1.
The drive shaft !8 is arranged in substantially parallel relation with the drum shaft l3 and is operatively connected with said drum shaft by a pinion gear 25 secured to one end of the shaft [8 in meshing engagement with a spur gear 26 secured to the drum shaft I3, as illustrated in Figure 2. The drum it? has the peripheral surface thereof provided with a plurality of recesses 30 which extend transversely of said surface and are arranged in uniform circumferential spaced relation to each other.
The recesses 30 are of slightly greater width than the sticks S, as indicated more particularly in Figure 18, for easily receiving the sticks therein. The depth of the recesses 30 is substantially equal to or slightly less than the thickness of the sticks-S So that only one stick may be carried in a recess at a time from the forward or discharge end of the hopper 9 into registration with the lower end of a vertically disposed bundle magazine 32.
The magazine 32 is supported by suitable brackets 33 connected therewith and with the center post 4 in an upright position substantially over the center of the shaft l3 with the lower end of said magazine in slightly spaced relation to the upper peripheral surface of the feed drum 12. The magazine 32 comprises a pair of vertically disposed guide rails 34 which are substantially U-shaped in cross section and are connected with each other by the brackets 33 and side plates 35 to extend in spaced substantially parallel relation with each other. The guide rails 34 are spaced from each other a distance substantially equal to the normal length of the sticks S for engaging the end portions only of the sticks and guiding said sticks as theyare moved upwardly through the magazine.
The hopper 9 is provided with a retainer or baiiie plate 35 which extends transversely of the hopper in inclined spaced relation to the forward end of the bottom 10, as indicated in Figures 1 and 14. The baffle plate 36 has the inner lower end thereof spaced from the feed drum 12 to provide an opening 31 between the baffle plate and the feed drum in which is positioned a selector roll 38. The selector roll 38 is preferably composed of rubber or other suitable flexible material and is mounted upon a shaft 39 disposed in substantially a horizontal plane transversely of the hopper 9.
The shaft 39 is journaled in suitable bearing members 43 secured, as illustrated in Figures 12 and 14, to the center post 4 of the frame I at the opposite side of said posts to the magazine 32. The diameter of the selector roll 38 is at least equal to the width of the opening 3'! so as to close said opening. The roll 38 is'continuously rotated in a clockwise direction, as viewed in Figure 14, by means of a belt 42 which extends around a pulley 43 secured to the shaft 39 and a'similar pulley (not shown) connected with the drive shaft of the motor 5. The selector roll 38 is arranged to operate in close relation with the periphery of the feed drum l2 so that sticks contained in the hopper 9 may not pass between the selector roll and the periphery of the feed drum I2 unless said sticks are substantially wholly contained within the recesses 36.
'Itwill now be observed that inasmuch as the feed drum I 2 and selector roll 38 are'both rotated in a clockwise direction, any sticks moved into engagement with the selector roll by the feed drum'will be moved away from the feed drum toward the baflie plate 35 by the selector roll, it being understood that sticks fully registering in the recess 30 will pass beneath the selector roll without coming into direct contact therewith. If, however, a stick carried upwardly by engagement with a recess 30 should be warped or twisted so as not to fully lie within said recess, such stick will come into contact with the selector roll and be moved thereby out of the recess away from the feed drum. The stick will then be moved by the remaining sticks in the hopper, which are maintained in a state of agitation by the feed drum, along the baffle plate 36 toward the upper end thereof and will eventually appear at the upper side of the mass o'fsitcks contained in the hopper 9 so that an attendant may observe such irregular or Warped stick and remove it from the hopper.
A the sticks carried in the recesses 30 move beyond the selector roll 38 into registration with the lower end of the magazine 32, they pass over a pair of fingers 45 provided on the free ends of a pair of carrier or lifting arms 46 which extend outwardly in substantially a horizontal plane from the magazine 32 and have the outer. end portions thereof secured to a U-shaped bracket 41 secured to a horizontally disposed rock shaft 48 which is journaled in suitablebearings 49secured to the auxiliary side rails 24 above the bearing members l9, as shown in Figures 1, 3 and 14. a
The bracket 41 is secured to the shaft 48 to rock therewith so as to bring the fingers 45 from their lowermost position in corresponding annular grooves or recesses 50 provided in the peripheral surface of the feed drum l2 in planes at the inner side of the guide rails 34, as illustrated more particularly in Figure 17, to a position a short distance above the lower ends of said guide rails for lifting the sticks S from the feed drum into the lower portion of the magazine 32.
The shaft 48 is intermittently rocked in synchronism with the registration of successive recesses 36 with the fingers 45 by means of an eccentric 52 secured to the drive shaft I6 inter mediate the pinion 25 and the bearing member 23 adjacent thereto, as illustrated in Figure 3. An eccentric rod 53, which is connected with the eccentric 52 by an eccentric strap 54, is pivotally connected, as at 55, with one end of the rock arm 56 which has the other end thereof mounted upon the rock shaft 48, as shown in Figures 3 and 4.
The arm 56 is secured to the rock shaft 48 so that rocking movement of said arm produced by the eccentric 52 and eccentric rod 53 will produce a sufficient rocking movement of the shaft 48 and bracket 41 during each revolution of the drive shaft l6 to actuate the fingers 45. The relation of the pinion 25 and gear 26 with respect toeach other and to the spacings of adjacent recesses 36 is such that the drive shaft l8 will be rotated one revolution as the feed drum l2 moves circumferentially a distance equal to the distance between two adjacent recesses 36.
In the structure illustrated in the drawings, the feed drum I2 is provided with thirty-two recesses 30 so that the gear 26 has a pitch diameter thirty-two times greater than the pitch diameter of the pinion 25 and the pinion25 and drive shaft l8 rotates 32 revolutions to each revolution of the gear 26 and feed drum l2. It therefore follows that during each revolution of the drive shaft IS the feed arms 46 and fingers 45 associated therewith will complete one vertical cycle of movement and the position of the eccentric 52 on the shaft 18 is such that the upward movement of the arms'46 and fingers 45 will begin as each successive recess. 36 comes into registration with the lower end of the magazine 32. f
The grooves or recesses 56 in the periphery of the feed drum l2 are of such a depth that the fingers 45, when in their lowermost position, normally lie beneath the bottoms of the recesses 36 registering with the magazine 32 so that as the recessescome intoiregistration with said magazine'the sticks carried therein will be moved'over said fingers into position to be lifted out of the recesses during the upward movement of the fingers. The upward movement of the arms 46 and fingers is sufiicient to'bring the sticks carried thereby above the lowerends of a pair of guide or retaining belts 56 which are arranged at opposite sides of the path of movement of the sticks as they travel upwardly between the guide rails 34.
The guide belts 58 are arranged substantially midway between the guide rails 34 to extend from adjacent the plane of the lower ends thereof upwardly to a position above the stack of sticks to be collected at the lower end of the magazine 32. These belts are each trained over a pair of rollers 53 rotatably mounted upon corresponding spindles 65. The spindles 60, positioned between the-guide rails 34 and the center posts 4, are mounted in a bracket 6| having a pair of arms '52 by which the bracket is secured to the center posts 4, as shown in Figure 16. The spindles 66, associated with the belt at the opposite side of the guide rails 34 from the posts 4, are mounted in a bracket 64 having arms 65 by which said bracket is secured to a U-shaped frame 66 which is secured, as shown in Figure 16, to the center post 4.
The guide belts 58 are rotated about the rollers 59 by the frictional engagement of the sticks S with theinner' adjacent runs of the belts and, in order that the inner runs of the belts will be maintained against flexing outwardly awayfrom the sticks, the brackets BI' and 64 comprise a central flat portion El and 64 arranged intermediate the runs of the corresponding 'belts in inner runs with a predetermined number of sticks, I have provided a counting mechanism 61 which is actuated by the sticks during their movement from the feed drum l2 into engagement with the lower portion of the belt'53. This counting mechanism, as shown more particularly in Figures 17, 19, 20 and 21, comprises a bell crank lever 68 which is pivotally connected at 69 to a bracket 10 secured'to one side'of the frame 65,'as shown in Figures 16; 19 and 20. The bell crank lever has one arm I l extending downwardly from the pivot 69 and provided at its lower end with a laterally disposed V- shaped projection or tooth "'H which projects through an elongated slot 12 provided in'the lower end of the adjacent guide rail 34' into the path of movement "of the sticks S entering between the rails 34 and belts 58. The tooth member TI is yieldingly maintained in the path of movement of the'sticks S by a spring'13 mounted in a hole 14 provided in the upper portion of the bracket I0 and which engages a substantially horizontally disposed'arm E5 of the bell crank lever 63. The inward movement ofthe arm H toward the guide rail 34 is limited by a screw 76 screwthreaded in said arm and which is adapted to crank lever arm H.
abut against an adjacent portion of the frame 66. The arm 'II is pivotally connected, as at I8, to a yoke I9 which in turn is connected by a screw 88 with a second yoke 8| pivotally connected by a pin 82 with an arm 83 rotatably mounted on a shaft 84 which in turn is journaled in a bearing bracket 85 secured to the auxiliary side rail 24.
Rotatably mounted upon the pin 82 is a pawl 85 which has engagement with a ratchet wheel 81 secured to the shaft 84 to transmit rotary motion to said shaft as the pawl is rocked in one direction by the swinging movement of the bell One end of the shaft 84 extends some distance beyond the bracket 85 and has secured thereto a flanged sleeve 88.
Mounted upon the sleeve 88 is a pair of end disks 69 composed of insulating material and which support a pair of annular rings 98 and 9|, as shown in Figure 19. One of the rings 98 is composed of brass or other suitable electrical conducting material while the other ring 9| is composed of fibre or other suitable insulating material. The rings 98 and 9| are spaced from each other by a disk 92 mounted upon the sleeve 88 intermediate the disks 89. The rings 98 and 9I and disks 89 and 92 are clamped to the sleeve 88 and to each other by the cooperation of the flange, as 88', of the sleeve and a nut 93 screw-threaded on the sleeve. A washer 94 may, as shown, be positioned between the nut 83 and the adjacent disk 89. The ring member 8| is provided with a peripheral slot or recess 9| in which is positioned a contact segment 95 composed of brass or other suitable electrical conducting material.
Positioned over the rings 98 and 9| is a pair of spring pressed brushes 91 which are mounted in apertures provided in suitable brush retaining members 98 secured to a plate 99 which in turn is mounted on an extension 85 of the bracket 85. The plate 99, as indicated in Figure 19, is composed of insulating material so that the brush members 91 and the supports 93 there- 'for are maintained in insulated spaced relation with respect to each other and to the bracket 85. The brushes 91 are connected in series with a solenoid I88 by suitable wires, as I8I, secured by screws I82 to the retaining members 98. The a contact segment 96 is electrically connected with the ring 98 by a pin I83 secured in said segment and ring so that when the segment is in contact with the brush 91 associated with the ring SI the circuit is completed between the brush members 91.
The solenoid I88, as indicated more particularly in Figure 1, is secured to a plate I85 which in turn is mounted on the end posts 3 of the frame I. The solenoid I88 has the plunger thereof operatively connected with one end of a link I88 which has the other end thereof pivotally connected by a bolt and slot connection I91 with one end of a rock arm I88. The arm I88 is mounted upon a rock shaft I89 which is journaled in suitable bearings II8 secured to the end posts 3. The arm I88 is maintained in a normal substantialy horizontal position with the aid of a spring I I2 mounted on the solenoid plunger be tween an extension I85 of the bracket I85 and a head II3 mounted on the upper end of the plunger.
The inner end of the arm I88 is forked, as at 7 I88 (Figure 14), and connected by pins II5 with a sleeve IIB mounted on a stud III between two nuts II8 screw-threaded on said stud. The stud is positioned in a vertical plane adjacent the magazine 32 and has the lower end thereof provided with a yoke II9 which is pivotally connected by a pin I28 to a link I2I which in turn is secured to the transverse portion I22 of a U- shaped plate I23. .The plate I23 has the arms thereof pivotally connected by a pin I24 with a U-shaped bracket I25 which in turn is secured to a U-shaped slide I26.
The slide I25 has the arms thereof slidably mounted in a pair of vertically disposed channel way bars I28 which are maintained in substantially parallel relation with the guide rails 34 by two pairs of brackets I29 secured to the center posts 4, as illustrated in Figures 1 and 15. The plate I23 has secured thereto a pair of feed bars I 38 which extend downwardly from said plate to within a short distance of the lower ends of the guide rails 34. The lower ends of the feed bars I38 are each provided with a laterally 'disposed finger I3I which projects from the respective bar toward the plane of the rails 34.
It will now be observed that inasmuch as the plate I23 is pivotally connected with the slide I26 and with the rock arm I88, vertical movement of said arm tends to produce a rocking movement of the bracket I23 about the pin I24. The amount of this rocking movement of the bracket I23 is limited by a stop screw I33 which is clamped to the transverse portion I34 of the slide I26 by two nuts I35, as shown in Figure 14. The screw I33 has the inner end thereof extended through a relatively large opening I22 in the transverse section I22 of the plate I23. The inner end of the screw I33 is provided with a head I36, while a nut I36 is screw-threaded on the screw to cooperate with said head for limiting the amount of movement of the plate I23 with respect to the screw. The downward movement of the slide I26 is limited by a pair of screws I3'I carried by a cross bar I38 which extends beneath and is secured to the way bars I28.
It will now be understood that when the slide I26 is held by the screws I3'I against downward movement and the solenoid I88 is de-energized, the action of the spring H2 and weight of the inner end of the arm I88 and stud II! will cause the plate I23 to rock downwardly until limited by the nut I36 on screw I33. This downward rocking movement of the plate I23 produces a suflicient rocking movement of the feed bars I38 outwardly to maintain the fingers I3I of said bars in spaced relation to the transverse plane of the guide rails 34 out of the path of movementof the sticks S as they are moved upwardly by the carrier arms 45, as indicated by full lines in Figure 18.
When the rock arm I88 is actuated by the solenoid I88 the initial upward movement of the inner end of said rock arm.will cause the plate I23 to pivot upwardly about the pin I24 until the swinging movement thereof is limited by the head I36 of screw I33 before upward motion is produced on the slide I26. During this swinging movement of the plate I23, the feed bars I38 will be swung toward the guide rails 34 so as to bring the fingers I3I thereof beneath the lowermost stick S positioned at the lower end of the guide rails 34, as indicated by broken lines in Figure 18. As the rock arm I88 continues its upward movement the slide I26 and feed bars I38 will move in unison therewith and will produce a corresponding upward movement of the stack of sticks assembled between the guide belts 56 to bring said sticks into engagement with the wrapper for securing them together.
The wrapper or labels L are cut from a strip or ribbon of paper P wound in a roll R which is carried by a spool I40 mounted on a shaft I II carried in bearings I42 secured to the auxiliary side rails 24, as shown in Figure 1. One or both of the bearing members I42 may be constructed in sections with one of the sections, as I42, hingedly connected to the other section and releasably maintained in holding engagement with the shaft MI by a screw I44 and thumb nut I45. The paper extends from the roll Rupwardly over a guide roll I46 mounted on ashaft I41 carried by supporting plates I49 secured to the upper end of a standard I49. 7
The standard I49 has a U-s'haped'base I59 which is secured, as shown in Figures 1 and 14, to the upper positioned auxiliary side rails 24 at opposite sides of the shaft 48. The paper or ribbon P normally extends from the guide roll I46 over a horizontally disposed shelf I52 secured to the plates I48 and thence inwardly between the guide rails 94 to asubstantial distance beyond said rails into a position between a pair of jaw members I53.and I54. A spring actuated brake plate I56 is shown pivotally connected, as at I51, to the outer ends of the plates I48 in spaced relation to the guide roll I46. The plate I56 extends toward the roll I46 from the pivot I51 and has the free end thereof engaging the paper passing over said'roll for frictionally maintaining the paper taut as it is drawn forwardly over the roll. I
Mounted over the shelf I52 is a guide plate Q69 which is rotatably mounted on a pin !6I mounted in the plates I49 above the shelf I52. The guide plate I69 is adapted to rotate about the pin IBI as the paper is moved upwardly from the normal horizontal position thereof by a knife blade I62 which is slidably mounted for vertical reciprocative movement ina'lpair of guide ways I53 connected with the standard I49. A second knife blade I65 is secured to the upper end of the guide ways I63 to cooperate with the knife blade I62 for severing the labels or wrappers from the strip of paper P. The knife blade I65 is maintained in a fixed position with respect-to the standard I49.while the knife blade I62 is moved toward and from the knife blade I65-by the operation of the rock arm I98 in the following manner:
The knife blade I62 is provided with a bearing block I66 in which is rotatably mounted one end of a U-shaped rod I61. The rod I51 extends upwardly from the block I66 and has the upper arm I68 thereof normally extended across the upper end of a lug I69 secured to the slide I26, as shown in Figure 14. A throw-out cam I19 is secured to one of the way bars I29 in upward spaced relation to the lower ends thereof in the path of movement of the arm portion I68 of the rod I61 and at one side of the path of movement of the lug I69. The spacing of the throw-out cam I19 from the normal lowermost position of the lifting lug I69 is such that when the slide I26 is moved upwardly the rod I61 will engagethe throw-out cam and be moved from engagement with the lug I69 after the upper edge of the knife blade I62 has passed upwardly a short distance beyond the lower edge of the knife blade 865. As the rod I61 is moved out of engagement with the lug I69, the knife blade I62 and said rod will fall by gravity to their lowermost position against a stop I12 connected with the standard I49. As the slide I26 returns to its lowermost position, the upper end I68 of the rod I61 will be engaged by the adjacent tapered surface I69 of the lug I69 and moved outwardly until it registers with the upper end of the lug, whereupon said end member I68 will move by gravity over the upper end of the lug I69 in position to be engaged by said lug as said lug is again moved upwardly by the slide I26.
' The jaw members I53 and I54, as shown more particularly in Figures 10 and 14, are carried by a slide bar I15 which is mounted between a pair of horizontally disposed guide bars I16 arranged over the hopper 9. The outer ends of the guide bars I16 are secured to the end post 2 while the inner ends of said guide bars are secured to a bracket I11 which in turn is secured to one of the center posts 4, as shown in Figures 1, 6 and 14. The jaw member I53 is formed integral with the forward or inner end of a substatially fiat thin carrier plate I 19 which has the outer end portion I89 thereof increased in cross sectional area and secured to a spacing block I6! by screws I82, said spacing block I8I being in turn secured to the slide bar I15 by screws I83, as shown more particularly in Figures 10 and 11. The jaw member I54 is pivotally connected, as at I64, to a bracket I secured to the under side of the plate I19 in inward .spaced'relationto the jaw member I53. The jaw member I54 is yieldingly urged toward the jaw member I53 by a spring I86 interposed betweenthe bracket I85 and a tail piece I91 formed. integral with the jaw member I54.
When the jawmembers I53 and I54 are in their normal outermost position, as indicated in Figures 10 and 14,,the jaw I54 is maintained in the open position against the action of the spring I86 by a trip block I88 secured to the lower guide rail I16 adjacent the inner end thereof by the engagement of said trip block with the camsurface I81 formed On the tail piece I91.
The plate I19 is provided with an opening I99 spaced outwardly a short distance from the jaw members I53 and I54. An L-shaped anvil I9I is mounted in the opening I99 for longitudinal reciprocative movement therethrough. The anvil I9I has one side portion I92 thereof extended above the plate I19 and connected with a stem I93 which extends outwardly from the anvil through a supporting block I94 secured to the plate I19 adjacent the outer side of the opening I90. The outer end portion I93 of the stem I99 is reduced in diameter and slidably received in a sleeve I95 which inturn is mounted in a second supporting block I94. The sleeve I95 has screw-threaded engagement with the block I94 so as to be adjusted longitudinally with respect to said block and is secured in the adjusted position by a lock nut I96 mounted on the sleeve. The anvil I9I is yieldingly urged inwardly by a spring I91 mounted on the stem I93 between the inner end of the sleeve I95 and stop nuts I98 screw-threaded on the inner end portion of the stem I93. The inner movement of the anvil I9I is limited by the engagement of a nut I98 with the block I94. The inner position of the anvil I9I is normally at the inner side of the opening I with the forward or innermost edge of the side portion I92 of the anvil in close proximity to the inner transverse side of the opening, as illustrated in Figure 10. After the proper normal inward position of the anvil I9I has been determined by the manipulation of the nuts I99, the tension of the spring I91 may be increased or decreased, as desired, by adjustment of the sleeve I55 with respect to the supporting block The jaws I53 and I54 and the carrier plate I19 are normally positioned at the opposite side of the magazine 32 from the paper guide roll I48 and are reciprocated toward and from the guide roll by a crank arm 288 secured to one end of a stub shaft 2M journaled in axially spaced bearings 282 provided on a bracket 258 secured to the end posts 2 and 2' of the frame I, as illustrated in Figures 1 and 6. The crank arm 208 is operatively connected with the plate I18 by a pitman 2G5 pivotally connected with arm 285 and with the slide bar I by crank pins 285, as shown in Figures 6 and 11.
The shaft Zill is rotated by the feed drum shaft I3 by a chain belt 251 trained around sprocket wheels 258 and 288 mounted on the shaft 2M and on said drum shaft I3, respectively, as indicated in Figures 1, 2, 6 and '1. The sprocket 258 is keyed or otherwise secured to the shaft I3 while the sprocket wheel 288 is keyed to a sleeve 289 which is rotatably mounted on bearing members 2H1 carried by the shaft 2!". Rotation of the sprocket wheel 228 therefore produces rotation of the sleeve 229 and said sleeve is secured to or made integral with a ratchet wheel 2! I, as shown in Figure '7.
The ratchet wheel 2| I is operatively connected with the shaft 28I to transmit rotary motion to said shaft by a clutch mechanism 2l2 shown more particularly in Figure 8. This clutch mechanism 2 I2 consists of an arm 2 I3 secured to the shaft 2M adjacent one side of the ratchet wheel 2 by a pin 2I4. The outer end of the arm 2I3 is pivotally connected by a pin 2I5 with a pawl 2I6 which is adapted to engage V-shaped teeth 2II' of the ratchet wheel 2II.
A spring 2I1. connected with the arm 2I3 and pawl 2I6 urges the pawl into engagement with the ratchet wheel for operatively connecting the arm and wheel to each other. The pawl 2I5 is provided with a lateral projection 2I8 which is adapted to engage a stop bar 2I9 slidably mounted in a bracket 22!! carried by the bracket 203, as shown in Figure 8, for movement into and out of the path of movement of the pawl extension 2I8. When the extension 218 engages the stop bar 2IS during rotation of the arm 2.!3 in unison with the ratchet wheel 2! I, the pawl 2I6 is moved out of engagement with the ratchet wheel against the action of the spring 2E1 and said arm and shaft 2IlI are maintained against further rotation. The stop bar Us is automatically moved out of the path of movement of the pawl extension 2I8 by the action of the solenoid I upon the arm I88.
The means for actuating the stop bar 2i & comprises a rod 222 pivotally connected at one end by a bifurcated sleeve 223 and pin 224 to the stop bar 2E9. The rod 222 extends from the sleeve 223 lengthwise of the frame I toward the solenoid I58 and is connected by a shouldered bolt 224' with a slotted arm 225 secured to the shaft I89, as shown in Figure 5, the shaft I 89 being secured to the arm I98 to rock therewith.
The rod 222 may, as shown in Figure 8, have screw-threaded engagement with the sleeve 223 so as to permit relative adjustment of the rod and sleeve to vary the over-all length of the rod. Furthermore, the arm 225 is provided with an elongated slot 225' for receiving the bolt 224 which permits the bolt to be adjusted toward and from the shaft I09 to vary the degree of longitudinal movement of the rod 222 and slide bar 2 I9.
The means for securing the label or wrapper around the stack of sticks contained in the bundle magazine 32 comprises an adhesive applying mechanism. This mechanism, in this instance, includes a glue pot 228 which is secured to the center posts 4 of the frame I a short distance below the inner ends of the guide bars I16, as shown in Figures 1 and 14. Journaled in the glue pot 228 to extend transversely thereof is a shaft 229 which has secured thereto a roller 238 adapted to rotate with the shaft, with the lower peripheral surface thereof submerged in the glue or adhesive carried in pot 228.
Retaining rings 23I may, as shown in Figure 12, be mounted on the shaft 229 at opposite sides of the roller 230 for preventing adhesive collecting on the shaft from the roller 230 traveling along the shaft to the bearings 232 for the shaft. The shaft 229 extends outwardly at one end beyond the glue pot 228 and has secured thereto a ratchet wheel 254 which is actuated by a pawl 235 rotatably connected by a shouldered stud or bolt 236 to a rock arm 231 rotatably mounted on the shaft 229 adjacent the ratchet wheel 234.
A spring 238 may, as shown in Figure 13, be connected with the arm 231 for urging the pawl 235 into engagement with the ratchet wheel 234. The rock arm 231 extends downwardly from the shaft 228 into the path of movement of an actuating arm 240 which is fixedly secured to a U- shaped plate or bracket 24I which in turn is secured to the slide bar I15 by two of the hereinbefore mentioned screws I83, as illustrated in Figures 10 and 11.
It will thus be observed that the actuating arm 248 is reciprocated in unison with the slide I15 and jaws I53 and I 54 and the relation of the forward end of the actuating arm with the normal position of the rock arm 231 is such that said rock arm will be actuated by the actuating arm as the slide I15 approaches the end of its in ward stroke for intermittently rotating the adhesive roller 230.
Associated with the adhesive roller 238 is a dauber mechanism which comprises a dauber blade or brush 242 connected at its upper end to one end of a horizontally disposed rod 243. The rod 243 extends laterally from the dauber or brush and is connected at its outer end to an arm 244 which is mounted on one end of a rock shaft 245, as shown in Figure 12. The rock shaft 245 is journaled in one side of a rock frame 245 which in turn is rotatably connected by a shaft 241 arranged over the shaft 245 in substantially parallel relation therewith to a bracket 248 which is secured to one of the center posts 4, as shown in Figures 6, l2 and 14, in a plane above the inner ends of the guide bars I16.
The rock frame 245 is yieldingly maintained in a normal vertical position by a spring 255 interposed between said frame and the adjacent center post 4. The rock arm 244 is yieldingly urged in angular relation with the rock frame 246 for normally maintaining the dauber blade or brush 242 in engagement with the roller 230 by a tension spring 25i mounted on the frame 245 with one end engaging said frame and the other end thereof engaging the arm 244, as illustrated in Figures 12 and 14.
The shaft 245 is rocked to bring the dauber blade or brush 242 from its downwardly inclined position in contact with the adhesive roller 230 to substantially a horizontal position for con tion of the wrapper or label L, as shown tacting a portion of the label or wrapper by means of an actuating plate 253 which is secured to one side of the U-shaped plate MI by screws 254, as indicated in Figures 6 and 22. This plate 253 extends forwardly from the plate or bracket MI and has the forward end 253' thereof adapted to engage a roller 255 rotatably mounted on a rock arm 256 intermediate the ends thereof. The rock arm 255 is secured to the shaft 245, as shown in Figure 12, to extend downwardly therefrom in substantially parallel relation with the rock arm 244 as indicated by broken lines in Figure 22.
It will now be observed that as the actuating plate 253 contacts the roller 255 the arm 255 will be moved from the downwardly inclined position indicated by'broken lines in Figure 22 to substantially a horizontal position as indicated by full lines in said figure. During this upward swinging movement of the arm 255, the frame 245 will be maintained in substantially a vertical position by the spring 253 which is of greater strength than the spring 25L In order that the arm 256 and, therefore, the brush or dauber 242 will be maintained against upward movement beyond a horizontal position by the engagement of the plate 253 with the roller 255, the plate 253 is provided with an extension 253" which projects forwardly from the end 253' and has a stop pin 25'! projecting laterally therefrom into the path of movement of the outer or free end of the arm 255, as indicated in Figure 22. The arrangement of the actuating'plate 253 with the plate or bracket 24I and roller 255 is such that the arm 256 will be moved to the horizontal position prior to the plate 253 reaching its innermost forward position so that after the arm 256 and, therefore, the dauber brush or blade 242 has reached the horizontal position, as indicated in Figures 22 and 23, continued movement of the actuating plate 253 will produce .a swinging movement of the frame 235 against the action of the spring 250 for moving the dauber plate forwardly in substantially a horizontal plane into contact with an adjacent porin Figure 24.
The operation of the machine will now be understood to be substantially as follows:
The sticks S to be wrapped are placed in the hopper 9 so as to extend transversely of said hopper in more or less parallel relation with each other. If the sticks are to be branded with a suitable token, this is usually accomplished just prior to the wrapping operation and such sticks are taken from the branding apparatus and placed in the hopper 9, care being taken to have the branded end of the sticks all at the same side of the hopper.
As the machine is now set into operation, as bythe action of the motor I5, the feed drum I2 will carry the sticks received in the recesses 33 from the hopper 9 over the fingers 45 of the arms 46 into alignment with the adjacent lower end of the bundle magazine 32. After a stick is thus positioned on the fingers 45 the arms 46 are rocked upwardly by the shaft 48 which is actuated through the medium of the shaft I8, eccentric 52, eccentric rod 53 and arm 53 to bring the stick into engagement with the lower end portions of the guide or retaining belts 58. The operation of the arms 46 is such that said arms will be returned to their lowermost position with the fingers 45 registering in the grooves or recesses 50 as the next succeeding-recess 30 approaches the lower end of the magazine 32 so as to receive the stick carried in said recess thereon.
As the sticks are thus successively moved from the feed drum I2 into the lower end of the magazine 32, the counting mechanism 61 will be successively actuated by the engagement of an end of each stick with the tooth member ll of the lever 68 for intermittently rotating the contact shaft 84 in the manner hereinbefore described. As soon as a predetermined number of sticks has been stacked at the lower end of the magazine 32, the circuit for the solenoid I00 will be closed through the switch elements or brushes 91, the contact ring 99 and segment 35 for energizing the solenoid. The energization of the solenoid produces an upward rocking movement of the inner end portion of the arm I03 which causes the feed bars I33 to first move into engagement with the lowermost stick S of the stack positioned at the lower end of the magazine 32 and then to move said stack of sticks upwardly through the magazine to a position above the horizontal plane of movement of the carrier plates I19.
During this upward movement of the stack of sticks, said sticks are brought into contact with the wrapper ribbon P which extends between the guide roller I43 and the jaws I53 and I54 inter mediate the guide rails 34 of the magazine 32, as indicated in Figure 14. As the wrapper ribbon is engaged by the uppermost stick in the upwardly moving stack, the corresponding portion of the ribbon will be moved upwardly thereby between the side plates 35 and drawn tightly over the uppermost stick and downwardly along the sides of the stack, as indicated in Figure 23. e
As hereinbefore described, the ribbon P is severed by the coaction of the knife blades I62 and I 55 so as to provide a wrapper or label L of such a length that the end portions thereof will extend downwardly a short distance below the lowermost stick in the stack at the end of the upward movement of the stack produced by the feed'bars I30. Simultaneously with the upwardmovement of the rock arm I08, the shaft ZIII is automatically connectedwith the drive ratchet wheel ZII for actuating slide I15 by the withdrawal of the stop bar 2I9 from engagement with the pawl extension 2I3 through the medium of the shaft I29, arm 225 and rod 222.
The speed of rotation of the shaft 2m and the length of the peripheral surface of the contact segment 96 are such that the forward end of the carrier'plate I19 will pass beneath the stack of sticks just prior to breaking of the solenoid circuit and therefore the de-energizing of the solenoid and downward movement of the feed bars I30 so that the stack of sticks will be maintained in its uppermost position by the carrier slide when said stack is released by the feed bars.
As the forward end of the carrier plate passes beneath the stack of sticks maintained between the side plates 35, the end of the wrapper projecting below the stack of sticks adjacent the approaching carrier plate will be bent laterally beneath the stack of. sticks while the end of the wrapper or label will be bent laterally in the same direction so as to extend away from the stack of sticks, as indicated in Figure 23. As the carrier plate moves forwardly to such a position that the opening I therein registers with the lower end of the stack of sticks, the end of the label which is bent beneath the stack will be engaged by the anvil I9I and maintained in the folded position thereby, as indicated in Figure 23. Continued forward movement of the carrier plate causes the anvil to remain relatively stationary due to the engagement thereof with the sticks so that said anvil moves longitudinally through the opening I99 during the continued forward movement of the carrier plate. This relative movement of the anvil and carrier plate produces a slot, as I98, Figure 24, between the forward edge of the opening I90 and the adjacent end I92 of the anvil through which the end of the wrapper or label which previously extended over the forward portion of the plate projects downwardly as said forward portion of the plate passes beyond the label end, as indicated in Figure 24.
At about the time the forward end of the carrier plate approaches the magazine 32, the roller 255 of the adhesive applying mechanism will be engaged by. the actuating plate 253 sothat as the opening I90 in the carrier plate registers with the magazine 32 the dauber plate 242 will be moved to the horizontal position, as indicated in Figure 23, in substantial registration with the adjacent side of the magazine. During continued forward movement of the carrier plateand actuating plate 253, the dauber blade 242 will be moved forwardly in a horizontal plane to such a position that when the end of the wrapper moves downwardly through the opening slot I90, said Wrapper end and dauber blade will come into contact with each other for applying the adhesive to the wrapper as the carrier plate reaches the limit of its forward movement.
As the carrier plate begins its return movement, the anvil I9.I will remain in contact with the adjacent portion of the label until said anvil again approaches the forward portion of the opening I90 at which time the forward portion of the carrier plate adjacent the opening I so will come into contact with the end of the wrapper extending through the slot I98 and will fold said latter end of the wrapper laterally beneath the opposite end of the wrapper engaged by the anvil I9I and will press said ends of the wrapper tightly against each other due to the added material positioned between the forward portion of the carrier plate and the stack of sticks provided by said folded ends of the wrapper.
If it is desired, an electric heating element, as indicated at 260, of any suitable construction may be secured to the under side of the carrier plate adjacent the forward end of the opening I90 for maintaining the adjacent portion of the plate at such a temperature that the adhesive will be rapidly dried and thereby fixedly secure the overlapping ends of the wrapper to each other as the carrier plate moves out of engagement therewith.
During the initial return movement of the carrier plate I19, the dauber blade 242 will be moved rearwardly by the action of the spring 250 upon the frame 246 until said frame assumes its normal vertical position, after which the dauber blade will be swung downwardly by the action of the spring 25I until said blade again engages adhesive roller 230 of the glue pot.
As the carrier plate approaches its innermost position, the jaw members I53 and I54, which are normally maintained in their closed position by the spring I86, will be moved to the open position by the engagement of the cam I81 with a trip arm 262 carried by a bracket 263 in the path of movement of saidcam. The relation of the trip arm 262 to the knife blades I92. and I65 is such that the jaws will be opened just prior to said jaws coming into engagement with the forward end; of the wrapp r ribbon which has previously been severed by the knife blades from the wrapper wrapped about the stack of sticks positioned between the magazine side plates 35; As the jaws move to the end of their inward movement over the free end of the wrapper ribbon, the tail piece I81 moves beyond the trip arm I62 permitting said jaws to be closed upon the end of the wrapper ribbon'by the action of the spring I86.
As the carrier plate begins its return outward movement the jaws which grip the ribbon will pull said ribbon forwardly therewith through the magazine 32 over the path of movement of the succeeding stack of sticks to be moved upwardly through the magazine. As the tail piece I81 of the jaw member I54 approaches the trip arm 262, said trip arm will be moved outwardly from the normal vertical position thereof maintained by a stop screw 264 and a spring 265 connected with said trip arm and the bracket 263 at opposite sides of the pivotal connection of the trip arm with the bracket 263 and be moved outwardly with said tail piece against the action of the spring 265.
As the carrier plate approaches its outermost position, the jaw members I53 and I54 will again be opened by the engagement of the tail piece I81 with the trip arm I88 so as to release the adjacent end of the wrapper ribbon. This cycle of movement of the various units of the machine may continue as long as sticks are maintained in the hopper 9 and the machine maintained in operation by the motor I5. As succeeding stacks of sticksare moved from the lower end of the magazine 32 to an intermediate position between the side plates 35, the previously wrapped sticks contained between the side plates 35 will be engaged thereby and moved upwardly throughv the upper end portion of the magazine and deposited upon a suitable conveyor (not shown) which may be associated with the frame I. adjacent the upper end of the magazine.
Although I have shown and particularly described the preferred embodiment of my invention, I do not wish to be limited to the exact construction shown as various changes both in the form and relation of the parts thereof may readily be made Without departing from the spirit of the invention as set forth in the appended claims.
