ROLL-SUPPORT.

Specification of Letters Patent.

Original application filed September 23, 1910, Serial No. 583,438. Divided and this application filed Januaryv 25, 1911.

To all whom it may concern:

Be it known that I, OTTO THIEME, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Roll-Supports, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a front elevational view of my improved device, with roll in position; Fig. 1 is a detail view; Fig. 2 is an enlarged detail view, partly in section; Fig. 3 is an enlarged cross-sectional view.

My invent-ion relates to an improvement in supports for paper rolls, to be used more especially on tabulating machines. Rolls of varying widths are used, and it is necessary to provide some form of retaining or guiding means on the supporting spindle to hold the roll in proper position relative to the operating parts of the machine, and especially the printing mechanism.

It is the object of my invention to provide a simple form of collar or washer to be applied to the roll spindle to properly position the roll thereon.

A further object of my invention is to provide adjustable part-s mounted in either end of the spindle to allow the latter to be properly positioned and held on a supporting bracket.

This application is a division of my copending application No. 583,438, filed September 23, 1910.

Referring to the drawings, 1 indicates the supporting bracket having upturned sides 2 and 3, with properly shaped notches 4L and 5, within which the spindle 6 of roll 6' is to be positioned. The form of bracket is entirely immaterial and any of the well known types may be used with my improved roll support.

My improvement relates to the construction of spindle 6 with a series of grooves 7 8, 9, -7, 8 and 9 on either end of the spin dle. I do not intend to limit the construction to this number of grooves, but any desired number may be used, as it is only necessary to provide a sufficient numberto allow for the differentpositions of retaining collars or washers 10 and 10. These collars orwashers are of similar form, and, as illustrated in Fig. 3, are provided with a pivoted catch member 11 pivoted at 12 in a slot 13 cut in the periphery of the collar having a projecting finger 14.

A spiral spring 15 is situated beneath the catch in a slot 16, to bear on the under side of the finger piece 14. The catch is provided with a projection 17 adapted to engagethe grooves 7 8 or 9 of the spindle. In this manner the collars are retained in position on the spindle 6, and the distance between the collars 10 and 10 may be changed by operating the finger piece to release the projection from the groove and sliding the collar longitudinally of the shaft to a position over another groove. As shown in the drawings, the collars are provided with a hub portion 18, but this is not always essential.

The spindle 6' is bored at either end19 for the reception of a spiral spring 20. This spring acts upon pin 21 projecting from the end of the spindle 6. The pin is provided with a projecting collar 22 at one end, which engages with a sleeve 23 tightly fitted within the bore 19 of the spindle 6. The pin 21 is provided at its outside end with a knurled portion 24, and adjacent thereto, a grooved portion 25 having beveled sides. As illustrated, I provide a pin 21 at both ends of the spindle 6, but it is apparent that one only mightbe used and the opposite end of the spindle made of suflicient size to be journaled within the bracket.

The notches 1 and 5 in the sides 2 and 3 of the bracket are shaped of sufficient width at the top for insertion of the grooved portion of pins 25 and at the bottom to fit the diameter of the spindle itself. By this means, the spring pins 24: may be drawn toward each other and inserted within the bracket sides, when they are released, and the spindle itself becomes seated in the lower portion of the notches, which prevents the spindle from being withdrawn from the bracket until the pins are again moved inwardly to register the grooves 25 with the notches 4 and 5.

The improvement described might be used in a variety of different arts where rolls of paper, cloth and other material are to be supported. It is especially useful in connection with'a t-abulating or calculating mechanism, wherein the position of the paper relative to the printing mechanism is important. Otherwise, the columns of figures would not be properly positioned on the sheet. As the market provides paper rolls of varying sizes, I have formed the grooves in the spindle to accord therewith, but any number and position of grooves might be provided.

I am aware that minor changes in the construction, arrangement and combination of the Various parts of my improved device can be made and substituted for those herein shown and described without departing from the spirit of my invention.

What I claim is:

A roll support comprising a spindle, said stained within said recess in contact with lentto'the diameter of the body portion of said pin, said bracket being also provided with a slot leading into said opening, said slot being substantially the width of the grooved portion of said pin, the parts being arranged in such manner that said pin may be forced against said spring and placed in the opening in said bracket through said slot, substantially as described.

In testimony whereof I hereunto afliX my signature in the presence of two witnesses, this 21st day of January, 1911.

OTTO THIEME.
