To facilitate such removal a light tubular core gaarrapp r. ip f a y fran s i mp oyed into which the shaft is inserted and whichflQleiis of such internal diameter that the shaft can be freely Withdrawn "after the sheet or band has been-.wound thereon.
.iflurinvention .therefore'zrelates to means for Withdrawingtheshaftfrom ithe' roll, supportand carry .the .shaft .to proper position in a'linement with a preparedcore, .and .thenrs'lide the shaft into the core. .It further ;relates :to means :for snpportingtthe roll and. core :-in -:co-'operative:posiitans relative .to .the operating positions :of
in this machine.
In Fig. 4 a roll A of paper or other material is shown resting on the table I. The table is shown provided with a trough 2 adapted to hold the core B ready to receive th shaft 3 after it has been pulled out of the roll A. The purpose of the machine is therefore to pull the shaft 3 out of r the roll A, move it down and laterally into alinement with the core B in the trough 2 and slide it into this core.
The machine shown in the drawing comprises two side- frames 4 and 5 connected by a cross fram 6. These side-frames have inclined surfaces or ways 1 and 8 on which the shaft puller carriage is slidably mounted. This carriage comprises the slides 9 and Hi connected by the chuck casing l I which may be of any desired cross section but is shown tubular, such tubes being obtainable of any desired length. Within this casing is slidable the clutch H! to whose ends is connected a chain I3 which may slide on the lower support i4 and on the guide bar l5 within the casing and is used to move the chuck back and forth within the casing. The chain passes around the idler sprocket wheel l6 and the driving sprocket wheel I! on the shaft I 8. On this shaft is a gear [9 meshing with th pinion on the moimtershaft 21 which also lcarri-es .a-ipulIey Z2.

' The rcasing Ial -lm.s-:-a. gap 'ZBsand vthe clutch 112. a ap at! :to r-receive the endcof '.the shaft i 3 :which maybe provided with acne or more collars 38'. When the casing .ais moved sup :until its I central line is level with the line of the shaftiinthe-iroll on the table, theiroll can :be rolled 1to. carr the endmf. :the a'shaft; into the clutch. 'iIhe'mraster switch 32 is then operated to cause the motor to move the clutch to the left (Fig. 1) thus pulling the shaft out of the roll.
Mounted on the sides 4 and 5 in bearings 40 are screws 4| which engage in nuts 42 carried by the guides 9 and Ill. The screws have bevel gears 43 at their lower ends meshing with gears 44 on the shaft 45 which carries a pulley 46 connected to the pulley 41 on the shaft of the re-' versible electric motor 48 by means of the belt 49.
Mounted on frame 4 is a bar 5| on which are adjustably mounted the switches 52 -and 53 of any well-known spring-closed type. These switches are in circuit with the master switch 54 mounted in any convenient position and are opened by a slide to stop the motor 48 when the casing has reached a desired position.
It will be understood that the machine is permanently positioned relative to the table I and that the casing l I is of proper length to con tain the shafts 3. The diameters of the rolls A may vary so that the elevation of the chuck must correspond to the height of the shaft in the roll. The position of the switch 52 would be changed if the diameters of the rolls vary greatly. The position of the switch 53 is permanent as it is positioned to cause the shaft in the casing to aline with the core B.
In operation, the casing II and chuck l2 are moved up to where the roll may be rolled to carry the end of the shaft into the end of the casing. The master switch 32 is swung to cause the motor 26 to move the clutch to the left in Fig. 1, pulling the shaft out of the roll into the casing, this 4 ing a frame having inclined guides, a shaft receiver slidably mounted on said guides, means to move the receiver on the guides, a chain within the receiver and a chuck connected to the chain and adapted to engage and end of the shaft, means to actuate the chain to pull the shaft from the roll into the receiver and to move the s si item the re r ,ws t res ll has shaft a small distance as the clutch moves up,
but the shaft soon drops back and the casing can" be raised to proper position to receive a fresh roll.- The weight or the casing and of the parts connected thereto may be counterbalanced 'by the beenfmoved tq"a,. second predetermined position. ""2'."A"machine to pull 'a' shaft 'from a roll of paper and move it to a new position comprising aframe having guides inclined to the horizontal,
a shaft receiver mounted on said guides, screws weights 60 on the cables 81 which pass over the rollers 62 and connect to the slides 9 and. III.
The switch mechanism for motor 26 (that m 1 motor 48 being about the same) is diagram----- matically shown in Fig; '7. The feed wire I8 connects to contacts H and 12. When the master switch'arm is in theposition'shown, contact plate [3 connects contact H .to wire. and contact 15 which is connected to contact 18 by plate 11 of the spring-closed switch 3|. From =31, current passes over wire 18 to the motor: and. over wire 19 to contact 80, plate 8| and contact 82 to return line wire 83. The switch 38 had been opened by the chuck 12. When the chuckengages the operating arm of the switch 3!, it will be opened and the motor stopped. a Whenthe master switch is swung to the position indicated by the dotted line (switch 30 being moved to its dotted line position by its spring) currentwill pass over line wire ID, contact 12, plate 8|, contact 85, wire 88,. plate 81 of switch 38, contact 88 and wire 89 to the motor, thence by wire 98, plate H and contact 82 toreturn wire 83.1 yWeclaim: v 1. A machine to pull a shaftfrom a. roll oi paper and to move it to a new position, compristo move the receiver laterally back and forth on .f'said guides and areversible electric motor to actuate the screws, a chain carried by the res ceiver, and aclutchattached to the chain and adapted to engage an end of the shaft, means to actuate the chain and clutch to draw the shaft into the receiver, a reversible electric motor to move the chain, clutch and shaft, and switches to limit the. movements of the parts 'ofthe machine. .7 GUSTAV A.
