The operating: lever" of this: shifting device operates through a path which is normally occupied by awebv roll so thatsit prevents the leverfromibeing thrown to neutral or to the high spee'd when the roll' is in place and the machine being op eratedtosimprovez the sideregister; r i

On one;of:.thez'bearingsi i is mounteda motor l-3 which. rotates with the bearing and with the reel as. the latter is: turnedt The motor shaft carries acpinion t4 meshing witha" gear l5 secured t o-la splinedshaft IS, the other e'ndof which shaft is supported the other bearing: block '4 aiatheother end of the" shaft -Fi'gs.- -3 to 6-- s'how' that the shaft i6= penetrates the spider 9 throughacavity, at the ends of which-are mount ed thrust: washers I 1: and I8. 'In this cavit'y, on thezshaft is; fixed ag-worm l9 which is secured against rotation. with respect to-the shaft 1 6 by keys 2m. These keys are held in place by thethrust washers I? and I8 so that when the spider ilsis=moved longitudina1ly, these keys travel al'ong theshaftwiththe worm IS. The worm-l Smeshes witha a straightiace gear 2l -rotatably mounted on: the shaft 22; This shaft? 22' is supported by aab'earing in the spider 9 and a removable bearing: 23. secured to the spider. By appropriate shoulders on the shaft-ZZ'; the removablebearing 235 serves -to -keep the shaft -fixed in longitudinal relatiomi s 7 On the upper end of the shaft Z2 is mounted a pinion 24 me'shing 'with-arack -25 securedto and extending alongthe-shaitti onuthisshaft 22 is s1idab1- y splined a clutch- 26; Itcarriesteeth Z1 atoneend' cooperating with complementary, teeth 28 on the gear 21 and" teeth 29- on the other endfor cooperating: mth compiementary teeth 30 of a; gear 32 which also is rotatably mountedion-the-shaf-t 22;; 'These parts of course are duplicated at the other ends l a back gearing as will be obvious.

- and the power will be transmitted from the shaft:

In full lines in Fig. 5 the handle 36 is shown in the neutral position so that the clutch 26 is not in contact with either of the two driving gears 2| or 32. The gear 2l meshes witha 7 smaller gear fixed on a shaft 4| and on this shaft is also fixed, or integral, a larger gear- 42 meshing with the gear 32..

handle 36 is thrown from the neutral to thepo sition marked Slow in Fig. 5, it is evident that the clutch teeth 21 and28 will cooperate sothat the, clutch is directly connected to the. .gear;2l. Now when the motor I 3 is connected with its power, power is transmitted from it to the shaft I6, worm l9, gear 2|, and clutch. 26 to rotate the shaft 22 at a slow speed to cause the pinion .24 to walk along the rack 25 for adjusting side register. The motor I3 is reversible so that the spider may be shifted in either direction. Of course, in this caseboth spiders are connected with the power by the operation of both handles 36. j .When the handle 36 is in the slow position (Fig. 5) for side register and the rolls are in place on thereel, the handle cannot be turned back to neutral position becauseit would engage the end of the roll (see Fig. 1).

When it is desired to shift either spider .to adjust the reel forrolls of difierent width, the above describedmechanismv is too slowand forv that purpose the back gearingand double clutch are introduced. 'Inthis case the handle 36 is moved to the position marked Fast/fin Fig. 5 and the clutch 26 will move, in the opposite di-. rection so that the teeth,29 and.36 are in mesh [6 through the worm l9, gears 2|, .40, 42 and 32 at a higher rate of. speed. It is. apparent that the chain of gearing is such, that the clutch 26,

will be made to run faster than .when it was clutcheddirectly withthe gear..2l and that it causes the shaft 22 to rotate at a higher speed. This walks the'pinion 24 along the rack 25. and shifts the spiders, or one of them, at a faster rate.

It will be noted that there is a handle 36 at each end of the machine and it is intended ordinarily to employ this higher speed for one spider at a time leaving the other clutch in neutral po-. sition. A cap 43 is providedfor. covering the openings in the spiders 8 and, 9 which houses the pinion 24. A cover 44 is used to close the housing containing the gear shift. Each spider, of course, carries a similar shifting arrangement as has been stated.

A simple means is alsoprovided for operating each .tractable spindle 12 which is carried in one of the spiders ,9 to facilitatethemounting of the paperrolls, This is shown'in Figs. 7 and 8. In

this case the spider 9 has a ho1e.45 bored inthe end of each. of its arms for the mounting of the chuck-46. A keyway 41, in thischuck cooperates with a guide pin 48 to permit short longitudinal motion but to prevent any rotatable motion of thej-chuck, A; worm 49 is centrally located.in

is an operating arm 59. retractable dowel 60 which may be operated by a handle fi l against the opposition of a spring 62.

This constitutes a When the chuck 46 and has one end supported in a hole 50 and the other carried in plug 4641 which is held in place by a screw 52, half in the plug and half in the chuck. A hand wheel 53 is pinned to the outside end of the worm 49 for the purpose of rotating it. The worm 49 rotates a gear 54 on a transverse shaft 55 mounted in bushings 56 and 51. on the spider 9. On oneend this shaft has attached to it a collar 58 and on its other end This arm 59 carries a A plate 63 is secured to the spider 9 and provided with a hole 64 to receive the dowel pin.

When the dowelpin is inserted in the hole 64 the chuck is then 'in its operative position and stays inthat position. This places the spindle I2 in the dotted line position in Fig. 8 or the full line position in Fig. 1.

The outer race of a ball bearing 65 at the end of the chuck 46 is secured to the spindle l2 by a washer 66. .Theinner race is carried on they chuck 46 and secured thereto by a washer.

61. Of course, a similar construction is provided oneach armof the spider. Therefore, it is apparent that the spindles. ll carried in the spider 8 may be stationary longitudinally but rotatable on their axes. Also when the arm 59 is moved to such position that the dowel enters the hole 64 the hand wheel 53 will be free to be turned to'move one of the spindles l2 toward or from the paper roll in an axial direction. This constitutes .a simple construction so that a finer regulation of the rotatable chucks maybe obtained bya single means.

Having thus described my invention and the advantages'thereof, I do not wish. to be limited to the details herein disclosed, otherwise than.
