ROLL-HOLDER.

Application filed June 29, 1914.

v 1 b all whom it may concern An object of the invention is to provide an improved. form of spindle for carrying the roll of paper.

The invention. possesses other advantageous features, some of which, with the foregoing, will be set forth at length in the following description, where I shall out line in full that form of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. In said drawings 1 have shown only one specific form of my generic invention, but it is to be understood that I do not limit myself to such form be- I cause my invention may be embodied in a multiplicity of forms, each being a species of my said invention. It is also to be understood that by the claims succeeding the description of my invention, I desire to cover the invention in whatever form it may be embodied.

In the drawings I have shown my invention as embodied in an autographic register, since that is one form of apparatus in which the invention may be advantageously employed, but it is to be understood that the invention may be embodied in other machines in which superposed sheets of paper are to be coincidently moved. This invention is not particularly concerned with what is written, printed or impressed on the paper or how such writing, printing or impressing is accomplished, but relates more particularly to the means of supporting the paper rolls. Referring to said drawings:

Figure 1 is a plan or top view of an autographic register embodying my invention, a part thereof being shown in section to illustrate the construction.

Fig. 2 is a longitudinal section of the hub on which the rolls are mounted.

I have chosen to illustrate my invention as embodied in an autographic register, that being one of the many forms of devices in Specification of Letters Patent.

which it may be embodied, and I shall de scribe it as illustrated, but the invention is not to be considered as limited to such embodiment.

The register consists of a suitable frame 2, a portion of which forms the platen 3, over which the sheets are drawn. At one side of the frame is a bracket 4, on which the paper rolls, 5, 6 and 7, and the carbon rolls 8 and 9, are mounted, the rolls being so arranged that the paper and carbon is properly fed over the platen 3.

The paper rolls are mounted on. spindles or rodsl-l, which are secured at one end only to the bracket 4, so that the rolls may be readily placed on or removed from the spindles. The rolls are formed with av hollow core of greater diameter than the spindles, and engaging in the opposite ends of the core are hubs or plugs 15 16, through which the spindle passes and which are journaled on the spindle. The body portion 17 of the hub is preferably formed conical so that it may be readily inserted into the roll, and the conical portion is of such diameter that when pressed into the roll it fits tightly thereto, so that the hub and roll rotate together. The hub is also provided with a flange 18 which bears against the end of the roll.

Means are provided for varying the turning or unrolling resistance of the roll, so that all of the rolls may be adjusted to present the same resistance, thereby insuring a coincident and equal feed of the various strips of paper. When a roll is of large diameter the ef ective lever arm of the withdrawn sheet is longer than when the roll is small, so that the resistance offered to turning by pulling on the sheets is 'difierent and on account of irregularities in construction, the resistance to turning varies, due mostly to different frictional resistances. I have provided. means whereby the resistances to turning of the rolls may be readily adjusted so that the sheets are regularly fed.

' Secured to each hub is an inner ball race member 21 with which are associated the bearing balls 22 and the relatively rotatable outer ball race member 23. The outer race member 23 projects beyond the outer face of the hub, and on hub 15, the outer race contacts with the bracket 4, and on hub 16, the outer race contacts with a Washer or plate 24:. By varying the pressure on the outer races the turning resistance of the roll is varied, and means are provided for vary ing this pressure. Engaging the free end of the spindle is a nut 25, preferably a wing nut, and between this nut and the outer race 28 is arranged a resilient element, such as a helical spring or a soft rubber ring or cylinder 26. A washer 27 is preferably arranged between the nut and the resilient element 20, so that rotation of the .nut will not twist the resilient element. By adjusting the position of the various nuts the tension on the various rolls may be adjusted so that the pull on each of the sheets of paper is the same.

I claim:

1. In a holder for a roll of paper, a spindle, hubs rotatably mounted on said splndle and adapted to hold a roll of paper, a nut on said spindle, a resilient element arranged between said nut and the adjacent hub, a ball race engaging said hub, a ball race engaging engaging said resilient element and being held by said first ball race against longitudinal movement outward and a plurality of balls between said races.

In testimony whereof, I have hereunto set my hand at San Francisco, California, this 23rd day of June 1914.

LUGIUS N. SABIN.

In presence of- H. G. PROST, P. S. PIDWELL.
