srann on SUPPORT FOR ROLLS or PAPER.

Specification of Letters Patent.

Patented Jan. 18, 1910.

Application filed April 8, 1909. Serial No. 487,676.

To all whom it may concern:

Be it known that I, LYMAN A. WHEAT, a citizen of the United States, residing at the city of Battle Creek, Calhoun county, State of Michigan, have invented certain new and useful Improvementsin Stands or Supports The objects of the invention are to provide a suitable support for a roll of paper which will effectively support and guide the same while it is being unwound and decreased from its largest to its smallest di mensions; and to provide a means of varying the resistance of the brake tension whereby the web will be deliveredwithoutanyoverthrow as the dimension of the roll decreases, so that the braking of the roll and the control of the same will be effective from the largest to the smallest dimension thereof.

A further object is to provide an improved means of adjusting the roll laterally and retaining it effectively in place to deliver in proper register to the printing press.

Further objects, and objects relating to details of construction, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clegrly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is an end elevation view, par

tially in section, of my improved stand. Fig. 2 is a Vertical longitudinal section on line 2-2 of Fig. 1, looking in the directionof the little arrows. Fig. 3 is an enlarged detail perspective view of one of the brake mechanisms. I

In the drawing, similar numerals of reference refer to similar parts throughout the several views.

Considering the numbered parts of the drawing, my improved roll stand or pedestal is made up of ends 1 and 2, which are suported on suitable foundations beneath the fioor. Each end is constituted at its top of a yoke 4 which'sup orts the carrying rolls 3 which are journa ed in the two ends and thereby supported. This yoke is depressed at the center and elevated at the sides into a V-shape and the rolls at each side cooperate with each other.

The roll of pa er 5 is rolled into the pedestal or base and, when it is of large size, it will rest upon the u permost pair of the rolls 3. The web is threaded down and a guide roll 6 is provided for delivering the same outwardly at 5' to the printing press. As the dimension of the roll decreases from the use of the pa er, it will descend onto the next pair of 1'01 5, and, as it still becomes further reduced in size, it will drop to the next lower rolls and so on until it rests on the bottom pair of rolls, substantially as indicated b the dotted lines in Fi 1.

A shaft extends between the en s 1 and 2-and terminates in a screw 8 at each end. Carried on these screws 8 are upwardlyprojecting arms at 9-9 which extend up at each end of the roll of paper and engage the central spindle thereof. The right hand arm- 9 is adjustable on a collar 10 by means of set screws 11, an ad'ustable collar 12 being at the op osite en of the collar 10, and secured in lace by a set screw 13. The shaft 7 is revo ved by the hand wheel 14 which, by the action of the screws 88 adjusts the pair of arms back and forth simultaneously, so as to carry the roll above. These arms 9 are an ported on pins l5-l5 at each end of the use so that they move in exactly parallel relation in shifting the position of the paper roll.

The paper rol is usually wound on a p pe 16, and into this I insert plugs 1717 WlllCll are spherical at their outer ends, where they contact with the arms 9-9.

A brake 18 on a suitable rock shaft 19 sup rted in a bearing 20 is provided for one of the rolls at one side of my base or stand, it only bein necessary to apply the brake to the one r0 1, engaging to properly control the roll of paper. n arm 21 on the brake extends laterally and the same s forced downwardly by the rod 22 which is screw-threaded in a suitable nut 2? WhlCh is set in the floor 24, the rod 22 being controlled by hand wheels 25. By this means, it will be seen that a ressure can be applied to the brake so t at, as the roll decreases in size, the brake can be ad usted to cause the necessary friction, so that its momentum will be overcome to properly control the same.

The adjustment of the arms 9 can be effected through the hand wheel 28 which extends above the floor and engages by means of a beveled gear 27 and a beveled gear 26 on the shaft 7, thus making it possible for the operator to control the position, either from the floor or below the floor as he may find necessary or desirable.

It will thus be seen that the rolls of this base or pedestal are supported in substantially a V-shaped framework, so that, as the roll of paper is reduced in size, it drops successively to the rolls beneath. By this means the roll of paper will pass from one set of rolls to another naturally and freely and easily and the brake on the different rolls can be adjusted so that exactly the right tension will be preserved on the web 5 of the paper.

In adjusting the roll back and forth, that is accomplished when the roll is in motion by the manipulation of the

hand wheel

28 or 14, as the case may be, as the roll very readily. yields and moves lengthwise when it is in motion and very slight pressure will be found to be sufficient to make it thus travel.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a pedestal for a roll of paper, the combination of the base ends 1 and 2; a V- shaped upper yoke portion, carrying a series of rolls; independent adjustable brake mechanisms for each of the rolls of one side of said frame; a shaft in the said base portion, screw-threaded at its opposite ends; upwardly-projecting guide arms suitably guided and controlled by the said screws for applying pressure to the rollto shift it onto the pedestal; a pipe with spherical plugs inserted into the same at the center of the roll for contacting with the said arms; an adjustable collar at one end of said shaft connected to one of the guide arms whereby the same can be adjusted to contact with the ends of the rolls of different lengths; all coacting substantially as described and for the purpose specified.

. 2. In a pedestal for a roll of paper, the.

combination of a series of rolls supported on a V-shaped support; guides for the roll of paper to support the same upon the said rolls; and adjustable brake mechanisms to apply varying tension as the roll of paper of paper to support the same upon the saidrolls; and brake mechanisms to apply carrying tension as the roll of paper drops from the higher to the lower supporting rolls, coacting substantially as described and for the purpose specified.

4. In a paper roll pedestal, the combination of a suitable base for supporting rolls thereon; upwardly-extending guide arms on suitable guide pins; a screw extending through the said arms; and means for operating the same to shift the paper roll on its supporting rolls; and means for adjusting said arms to and from each other, coactin for the purpose specified.

5. n a paper roll pedestal, the combination of a suitable base for supporting rolls thereon; upwardly-extending guide arms on suitable guide pins; a screw extending through the said arms; and means for operating the same to shift the paper roll on its supporting rolls, coacting for the purpose specified.

6. In a paper roll pedestal, suitable supporting rolls for the paper roll; a central tubular spindle with plugs having spherical outer ends; and adjustable guide arms engaging the same, coacting as specified.

7. In a paper roll pedestal, suitable supporting rolls for the paper roll; a central spindle having spherical outer ends; and adjustable guide arms engaging the same, coacting as specified.

In Witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
