To .all whom t may concern:

Be it known that HARRY ARTHUR Foofrrronar, a citizen of theUnited States, residing at Harrisburg, in thercounty of Dauphin and Sta-te of Pennsylvania, has invented certain new and useful improvements in Storage Spools, of which the following is a specification, reference being had therein to the accompanying drawing.

Vlhis invention krelates to sto-rage spools of the kind upon Vwhich long paper and carbon strips are wound for use in connection with writing-adding machines. Y

The object or the invention is to produce a spool of inexpensive construction which may be quickly and conveniently located upon and secured to a supporting spindle.

Another object of the invention is to make the spool proper in the form of an inexpensive hollow core or sleeve, upon 4which the paper is wound and shipped` and adapted for separable conneetion with locating and securing flanges which are part of the machine equipment and serve yto quickly and conveniently locate and holdV successive cores upon the spindle as the supply of paper is replenished.

To the accomplishment of the above objects, the invention resides in the embodiment thereof to be hereinafter described, illustrated and claimed.

lnV the accompanying drawings Fig. l is 'a sectional elevation showing a spool spindle upon which is mounted a spool constructed in accordance with the invention.

Fig. 2 is a sectional view through the spindle and one of the flanges and disclosing the automatic flange lock.

Fig. 3 is a perspective view of a flange, a portion of the spindle and a portion of the spool core, clearly showing the manner in which the core and flanges are coupled.

Fig. l is a diagrammatic view illustrating the operation of the flange lock, and

f Fig. 5 is a detailed view of one of the spindle bearings.

The paper spindle l, is removably and rotatably mounted in bearings 2, carried by supports 3 and has at one end a knurled head 4l, by means of which the spindle may be rotated or drawn endwise. Ordinarily, however, the spindle is not movable endwise since the bearings 2 consist of two pivoted bearing plates 2u and 2", which are drawn into engagement with a reduced portion, 2c of the spindle, by a spring 2d, which must be overcome in order to spread the members 2"L and 2b apart to release the spindle. Between the bearings 2, the 4spindle supports a `pair of similar spool flanges 5, preferably of circular-form, asshown, and having a pint adapted to extendl into notches 7 in the ends of a hollow spool core 8, which lits approximately upon the spindle. The core 8 comes from the paper manufacturer with a long strip, web or sheetv of paper 9 wound thereon and is intended to rotate with the spindle l as the paper is drawn from the spool and used. The paper employed for different purposes is of different widths. rl`he spools, therefore, are or may be of different lengths.

The flanges are utilized as locating and securing means for the spools, being separably connected with the cores to permit the release and removal of a core from which vthe paper has been unwound and the: en-

gagement of another coreupon which anew supply of paper is received. These flanges 5while approximately fitting the spindle, are independently shiftable longitudinally thereof to accommodate any size spool in any desired location lengthwise of the spindle. Having been properly located and brought into engagement with or coupled to the core 8, the flanges must bel locked to the spindle to maintain the location of the spool thereon and compel its rotation therewith.

To accomplish this purpose each flange is formed with a peripheral recess l0 of sufficient depth to cause a. portion of the periphery of the spindle 1 to protrude therein, as shown in Fig. 2. lVithin the recess l0 is mounted on the pin 1l', parallel with the spindle, an eccentrically mounted knurled locking disc 12. The knurled periphery of the disc l2 bears against the spindle l with effective or ine'ective friction, according to the position of the locked disc on its axis. The disc 12 may be turned by hand to lock or unlock the flange from the spindle, inasmuch as its periphery projects slightly beyond the periphery of the flange and is therefore accessible for direct operation.

The purpose of the particular construction shown, however, is to secure the automatic locking of the flanges by the manipulation thereof without the necessity for the direct manipulation of the locking devices.

reference to Fig. 4, wherein the trueand ec-` centric centers of the disc are indicated and the variation of the engaging services of the spindle and disc from a true and eccentric relation, as indicated by dottedarcs struck from theeccentric center of the disc.

' It'will be: obvious that spindle l from one or bothv bearings,` the spool heads or flanges may be rotte'd relative to thelshaf't until free to move thereon, after vwhich the core 8 andone or both of the flanges may be withdrawn from the spindle. 'the spindle, the flanges vbrought into engage-l ment with the ends of the core and quickly locked in position either by-'turning -the flanges on the Spindle or holding theV same stationary while the spindle is rotated, the cramping orwedging cfr-the locking discs against the'spindle serving to securely lock the flanges and the spool core to the spindle in the selected location. Y i

It will, of course, be understood that while by releasing thev A new spoolmay then be slippedon mounted within :the'recess of the flange and having its periphery exposed ery at the periphof the flange and within the axial opening thereof.

-2f The combination with a spool and spindle,'of' a locking device carried by the spool and rotatable on an eccentric axis to engage the periphery of the spindle.

and eccentric locking devices carried by the flanges -to .engagev the periphery of the spindle.

In testimony whereof I hereunto affix my signature in the presenceof two witnesses` `HARRY ARTHUR FOOTHORAP.
