AUTO TUBE WINDER.

Application fiiea'ri rn 27, 1921. Serial No; 464,838.

To aZZ'w/zom it may concern:

Be it known that FREDERICK CoA'rns, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, has invented certain new and useful Improvements in Auto Tube VVinders, of which the following is a specification;

to whichblanks consisting of rectangular strips of paper may be fed andwhich will be delivered from the machine in the form of tubular can bodies. A second important object of the invention is to provide an improved machine for forming tubular can bodies wherein improved means is used for rotating a tube;

former at a predetermined point in its travel over a prescribed path.

A third important object of the invention is to provide an improved machine of this class having improved stripping means for removing the can body from-the former.

A fourth important object of the invention is to provide an improved machine of this class having an automatically operating intermittent clutch and a Oarrierhead driven from the clutch and carrying the can former so that, at stated intervals, the rotation of the former is stopped automatically while the winding and stripping operations take place. I r

A fifth important object of the invention is the provision of a machine of this class having an improved mechanism for holding the tube or body formers against rotation as the body is wound thereon.

A sixth important object of theinvention is the provision, in a machine of this clas's, of novel mechanism for holdmg the glued end of a blank down on the body of the blank until the same will adhere firmly.

With the above and other objects in view, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fullydescribed, illustrated in the accompanying drawings, and specifically claimed. Inthe accompanying drawings, like characters of reference indicate like parts in the several views, and

Figure 9 is a perspective View of one of the pressing devices herewith used;

In the embodiment of the invention herein illustrated there is provideda frame 10. Journalled in this frame is a main shaft 11 which is provided with a belt pulley 12 or some othersuitable form of drive. this main shaft is a pinion 13 which meshes with a gear'14 mountedon a shaft 15. At 16 is shown a clutch, the clutch being preferably of the type disclosed inmy copending application, filed the 27th day ofApril, 1921. and bearing-the Serial Number 464,831. In place of the pins shown in said copending application this clutch is provided, 011 one of its members 17, with a'series of teeth 18. On a stop shaft 20 is mounted the stop lever 21 of the clutch, this lever having ro tatably mounted thereon aroller 22 in constant engagement with the cam 23 fixed onthe shaft 11. Thusthe rotation of the shaft- 11 1 rotates thegcam 23 'a nd operates to free the lever '21 from the teeth 18 oneach rotation of said shaft 11. In the present instance the'rat'iobetween the

gears

13 and 14; is intended to be four toone and there are four of the teeth 18 so that the clutch 16 is disengaged from the shaft 15 four times a ratio of movement rather than diameterv since during the disengagement of the clutch j there will be a pause in the revolution of the shaft 15 it must be compensated as otherwise the shafts 11 and15 would not revolve in the properratio. On the shaft 15 1s mounted a spider or former carrier 24 provided with a seriesof bearings 25 wherein are rotatable mounted shafts 26 each carrying a body former 27 of the type described in my copending application bearing the Serial Number 464,834 and filed the 27th day of April 1921. That is to say each of these body formers is a hollow cylinder having a central cavity 28 with lateral ports 29 leading therefrom. Carried on the shaft 11 is a gear 30 which meshes with a gear 31. EX- tending through a vacuum box 32 is a vacuum pipe 33 which evolves with the gear 31 and carries on its end a disk 34 provided with a recess wherein is seated a rubber clutch and packing ring 35; Mounted on the shaft 11 is a cam 36' and a lever 37 pivoted at one end, as at 38, carriesa cam roller 39 engaging in the groove of the-cam 36. This lever 37 operates to oscillate once in each revolution of the shaft 11 and the cam 36 is provided with a dwell 40 wherethrough the roller passes. Moreover the; lever 37 is so connected to the shaft 33 as to move the latter as the lever oscillates, It will be noted that the lever 21 stops-the clutch and disengages the shaft 15 at a time when a former head 27 is in alinement with the shaft 33. Also at this time the lever 37 has moved to bring the head 34 into engagement with the former'28 which is in alinement. Consequently the head 34 acts as a fringe clutch and rotates this former. At the same time the movement of the lever opens a valve 41in a suction pipe 42, the valve being pro vided with operating handle 43 connected to I the lever 37 by a link 44. At 45 is a bearing 1 while one former 27 is revolved by the shaft wherein is slidably mounted a shaft 46 carrying gripper fingers 47. -M0unted slidably on each of the former heads is a stripper 48 having a rib 49engageable when in proper position, in grooved portions 50 of said stripper fingers. This shaft 46 is connected by pins 51 to the lever 37 These parts are so arranged and proportioned that during the disengagement of the main clutch and 33 the lever 37 will oscillate once to move the stripper 48 overthe former 27 just be-V hind thatformerwhichis alined' with the shaft 33. It will be seen that a suitable feed guide 52-isprovided :atthe properpoint to guide the paper :strip Srto the rotating former; -On-the head 25 are mounted pins 53 and on each of these pinsis provided-'a-sleeve "54 carrying atone end a presser finger'55 7 while at the otherend "each sleeve has an arm 56 provided-fat its ends'with spaced

prongs

57 and 58 the I prong '58 being-closer to the sleeve and'longer than'the prong 57.

i Projecting from each stripper48 is a pin 59.

Onithe shaft 115 is a sleeve-60 in which the shaft freelyrotates and at one end of this sleeve is an arcuate cam 61 having 'atits end i a projection 62. Extending from each of the arms 56 is a finger 63 which is so arranged that When the carrier head rotates these fingers 63 are brought successively into contact with the cam 61 in such manneras to lift the presser 55 away from theformer. From an inspection'of'Figure 3 it will be seen that the presser is kept well out of engagement with such former and upon arrival at the projection 62 is moved still further away from engagement. In order to accurately time the arrival of the pin59 in position to be engaged between the

fingers

57 and 58 there is provided on the shaft 11 a cam 64 which oscillates a lever 65 project ing from the sleeve 60. .Thus at each revolution of the cam 11, just as a respective finger 63 has rested on to the projection 62 the lever 65 will be drawn forward by a spring 66 and the cam 61 slipped from beneath said finger 63 allowing the presser ,55 to move toward the former. This operation takes place just as the former has been acted upon 7 stripper. It will be noted that this result is accomplished by aid of the action of the cams on the shaft 11 as Well as by the action of the cam 61, these cams being in such timed relation that the pin 59 makes nearly a complete revolution during the time that the presser 55 is held outward by the lug 62, this lever being released at the proper instant to permit the pin 59 t'o'drop between the fingers or jaws 57'and 58. r

From the foregoing it will be seen that the blanks are fed successively on the'former as they are brought around to position, the former being revolved once, the glued. ends of the blanks held down until the strip per stop is reached. At this time the strip-a per operates and the former is free to ree ceive another blank.- o 7 7 It will be noted that springsf67 and' 68" are used to hold the presser and-lever 21 inposition respectively; i

It is obvious that minor changes may be,

ventioiiwvithout departing from the matepresser islifted away to permit action of the rial principles thereof. Itisnot' thereforex desired to confine the invention to the exact, form herein shown and described, but it is wished to include all such'as properly come within the scope claimed.
