To all whom z't may concern.'

Be it4 known that I, GEORGE S. WrrHaM, Sr., a citizen of the United States, res1ding at Hudson Falls, county of Washington, State of New York, have invented certain new and useful Improvements in Machines for Making Paper or Fiber Tubes or Cores,.of which the followingI is a. clear, full, and exact description..

This invention relates to. machines for making paper or fiber tubes or cores, such as made by paper makers for use in shipping large rolls of paper to newspaper printing establishments. The said tubes or cores are substitutes for the well-known iron cores before used, and the object 0;@ the present invention is to improve upon the means for making papertubos or cores, which are nothing more than heavy tubes made of many wrappings or convolutions of glued paper which is wrapped about a mandrel or Winder shaft. As substitutes for ironA cores.

these paper cores or tubes prevent the large rolls of paper wound about them from collapsing atthe center, keep them circular and permit the paper to. be run completely out right down to the core; As these paper cores or tubes are ordinarily made, t-he machine is stopped from time to time and' the core or tube calipered in order te determine its finished diameter, and the ordinary way of getting it off of its mandrel or winding v shaft is to attach a block. at the endand to use a block and fall and man power. Under the present invention this is done away with, the objects gained being those of automatically stopping the machine when the tube or core reaches the desired diameter; the lift ing of one end of the mandrel or winder shaft from its journal; and thereafter the forcing or stripping of the tube from the mandrel or Winder shaft on which it is Wound, so that the`tube or core will be almost absolutely cylindrical and will be made in the best possible manner.

Other ob 'ects are to provide an efficient and practical machine for the purposes men'- tioned.

These being among the objects of the present invention, the same consists of certain features of construction and combinations of parts Ito be hereinafter described and then claimed with reference to the accompanying drawings illustrating a suitable embodiment of the invention, and in which- Figure l is a front elevation of the machine; Fig. 2 a plan; Fig. 3 a'transverse section on theline 3-3 Fig. l; F ig. 4 is an enlarged detail view of the means for gagling or determinatingthe thickness of the The paper roll from which the paper is supplied for the formationvof the tubes or cores is mounted on ashaft 3 at the rear of the machine and mounted in box bearings 4, the upper half boxes or bearings 5 being hinged at one end and provided at the other end with. tension screws or devices 6, for the purpose of giving .the web of' paper or material the proper tension as it is drawn forward in unwinding. The web passes over a guide roller- 7 mounted on the frame and between a pair of glue rolls 9` and 10, the lower of which dips into a glue pan 8.

The upper glue roll lOis journaledin boxes 11 which are'giiided in standards l2, rising from the frame 1, and whichv boxes are pressed downwardly by means of' pressure screws 13. A suiiici'ent amount of glue is taken up by the lower roll to spread a thin film of glue evenly across the lower surface of the web. The pressure screws 13 are adjustable so that the top. glue roll may be run at any desired tension to squeeze the web between the nips of the glue rolls, thereby adjusting the amount of glue required for the surface of the web. After leaving the glue rolls, the web passes under another guide roll 14 at the front part of the machine and from thence upwardly to a mandrel or Winder shaft 15. The web of paper is attached to said shaft. by wrapping it around until the next ply comes on top of the first, when the tension on this grips it hard enough so that the web is drawn forward as the shaft revolves. Said Winder shaft 15 is mounted to turn in bearings 16, 17, respectively at the left and right hand ends of the shaft. A counter shaft 18 1s provided which is journaled at one end in the frame and in the other end in an auX- iliary frame 18, and it carries a gear 19 which meshes With a gear 20 on the winder shaft 15. On the counter shaft is a belt pulley 21 and a clutch 22, the movable member of which clutch is operable by a lever 23. A cord or flexible connection 24 is attached at one end to the outer end of said lever and is guided over a guide pulley 25, from whence it passes downto and is attached to a foot lever 26. Clutch cut-out member 27 is pivoted at 28 to lever 23 and to it is attached a retracting spring 29, the purpose of which is to automatically re tract the cnt-out member and disengage the clutch members, for the purpose to be herevinafter stated. For the purpose of holding the clutch members in engagement, the clutch cut-out member 27 is held by a holdback or detent 30 mounted on the frame about midway of the length of the Winder shaft, said member 27 having a notch 3l to be engaged by or with said detent 30.

In conjunction with the clutch cut-out member and concomitant parts, means are provided for gaging or determining the thickness of the tube or core which is being formed about the Winder shaft and for automatically releasing the clutch cut-out member when the predetermined thickness has been obtained. comprise a stop or trip member 32 which is pivoted at 33 to a bracket or frame portion 32a carried by the frame 1. Mounted on the free end of the clutch cut-out member 27 as shown more clearly in detail in Fig. 4, is

'an adjustable set screw 34 which furnishes an abutment for the trip member 32 for the purpose of gaging or determining the thickness of the tube. A latch 35 is mounted on said bracket 32, which latch is operable for the purpose of engaging and holding the stop or trip member 32 up out of inoperative position while starting the cores or tubes on the winder-shaft. f

The operation of the clutch cut-out member 27 and allied parts is as follows The predetermined thickness of the tube or core to be formed is secured by releasing the stop or trip member 32 from latch 35 so that it will rest upon the Winder shaft 15. The abutment screw 34 is then adjusted in the end of the clutch cut-out member to such position'that if raised by a predetermined thickness of tube or core, the clutch cut-out member would be released from detent 30. It will be seen that as convolution after convolution of the tube or core is formed on the Winder shaft, the stop or trip member 32 is gradually raised, which tends to gradually release the member 27 from the detent Such means preferably 30. As soon as the predetermined thickness of tube or core has been obtained, the outwardly moving stop or trip member 32 and abutment screw 34 act to instantly disengage the member 27 from the detent 30, whereupon the member 27 is retracted by its spring thus disengaging the clutch members and stopping the rotation of the counter shaft 18. By these means various diameters of formed tubes or cores may be obtained, and the machine automatically stopped. WhenV the machine has stopped, the web of paper is severed from the formed tube or core and the same is ready to be removed or stripped from its Winder sha-ft. To set the described parts previous to the formation of another tube orcore, the foot or manually operated device 26 is depressed whereupon the clutch members are again engaged and the clutch cut-out member 27 is engaged with t-he detent 30; the other parts are then adjusted in an obvious manner.

Previous to the removal of the formed tube or core from the Winder shaft, itis proposed under the present invention to lift one end of said shaft. This is accomplished through the medium of a lifting lever 36 pivoted at 37 to the frame 1 and provided with a lifting roller 38 mounted on an upright support 39,`carried by said lever. A hinged support or link 39a is connected with the frame 1 at one end at 41, and at the other end with upright support 39 so as to hold the latter in roper position and to guide the lifting rol er properly in its movements. For maintaining the lifting lever 36 in its adjusted posit-ion a rack 42 is provided, the teeth of which are engaged by a spring pawl 43 mounted on said lever. The said lifting roller 38 is located directly under o-ne end, preferably the left hand end, of the Winder shaft, and receives the same in its groove. It is obvious that as the lifting lever 36 is moved downwardly, the roller 38 is moved upwardly and carries with it the end of the Winder shaft restin thereon so that the latter is brought to inclined position and is raised suiiieiently above the bearing at its raised end in order that the tube or c ore may be stripped off. The raising and inclination of t-he Winder-shaft is permitted by reason of the fact that thel bearing 17 is open at the top so that the shaft may be moved on the contact edge ofear 20 as a fulcrum. Obviously other suita le means to permit such movement may be used.

The removal of the formed tube or core is accomplished by the following means: A worm shaft counter to the Winder shaft 15 is mounted in suitable bearings of frame 1 and is provided at one end with a drive pulley 45 which is ordinarily constantly driven, and is not stopped when the other portions of the machine are automatically stopped as 'form a tube or core.

described. Parallel 'with the wrrn shaft 44 is a guide shaft 46 on which is hung, Qso as to be laterally shiftable thereon, aftrave'ler ar'm 47. The rear end of said arni is' guided on shaft 46, while the other end of .the armr extends forwardly in convenient position to the operator. Said arm is providedr a vhalf nut 48, the threads of which are adapted to mesh with and engage the worm shaft 44. Rising from the arm 47 is a stripper 49 which preferably extends transversely across one side of the Winder-shaft or roll and is adapted to engage with that end of the tube or core which is opposite to the direction in which the pushing movement is applied, as shown in detail .in Fig. 5. It will be 0bserved that the stripper 49 extends in the direction of the movement of inclination of the Winder shaft, so that when said shaft is inclined said stripper' will be in operative relation to the end of the tube or core which is engaged by said stripper. When the Winder shaft and thel formed tube or 'core have been raised as before described, the operator takes hold of the traveler arm 47 and brings the stripper 49 in engagement'with the end of the tube or core and engages the half nut 48 with the worm 44. As the worm shaft '44 is constantly rotated, the said shaft acts immediately upon the engaged parts to effect the removal and stripping off of the tub'e or core rfrom the Winder shaft. The Winder shaft is then lowered to its bearings and another tube or core can be formed.

rIhe preferable 'form of Winder shaft can be ascertained from Figs. 4 and 5 and from Figs. 6 "and 7 which, are views of 'opposite ends of the shaft. The main body of the shaft l5 is flat at one side at 51 and the flat surface tapers sli-ghtly from -end to 'end 'of the shaft. Along the fiat surface 51 the said body section is undercut so as t0 provide a slide-way 52, which is tapered hom one end of the shaft to the other. The shaft consequently is doubly tapered, with the result that at one end of the shaft as lshown in Fig. 6, the shaft is the most cut away in the 'direction of its radius and transversely, While at the -opposite end as shown in Fig. 7, it is the least cnt away. There is also a shaft completing section 53 which is of such cross section from end to end that when fitted properly against the Hat and cut-away portion of the body section 15, the shaft is completed and made a substantially true cylinder. Said section 53 is of the same length as the body section and is flattened correspond? ingly to the body section, the same having a coeXtensive tapered portion which is undercut and corresponds y in cross section with that of the slide-way in which it is received. When the said sections are pushed together end for end, the windershaft is readyfto Before the latter can be removed, rit will be necessary'to impart a blow orblows to the small end of the shaft completing section with the result that the latter may be driven out a suitable distance to thereby reduce the diameter of the shaft-- at the point of location of the shaft complet` ing section. rllhe tube or core may now be'` removed by the means before described. .What -I claim as `new and of my invention 1S y1.
