WINDING-ARBOR FOR PAPER-TUBE MACHINES.

SPECIFICATION forming part of Letters Patent No. 743,217, dated November 3, 1903.

Application filed June 16 1903.

To all whom it may concern:

Be it known that I, CHARLES A; BAILEY,

a citizen of the United States, and a resident of Cromwell, in the county of Middlesex and- State of Connecticut, have invented an Arbor for Paper-Tube Machines, of which the following is a specification.

In the manufacture of paper tubes some difficulty is experienced in removing the completed tube from the arbor, due to the shrinkage of the tube and also to its sticking to the arbor by reason of the paste that is applied to the paper in the manufacture of the article. To overcome this difficulty, I provide an arbor of improved construction which will readily free the tube by reducing the diameter of the arbor and when arranged for winding the paper thereon will present aplain or unbroken surface and practically a solid arbor.

With the above objects in view the invention contemplates the provision of an arbor comprising a spindle and semitubular parts or sections slidably mounted upon said spin- 7 die and adapted to rotate therewith, the aforesaid parts being intimately connected to complete the arbor and the connection being such that the diameter of the arbor will be reduced Within the tube to free the latter therefrom, all as hereinafter fully described,and specifically set forth in the claims.

In the accompanying drawings, which form a part of this specification, Figure'l is a plan view of a winding-arbor for paper-tube machines constructed in accordance with my invention. Fig. 2 is a longitudinal sectional View. Fig. 3 is a transverse sectional View on the line 3 3 of Fig. 1. Fig. 4 is a similar view 011 the line f 4 of Fig. 1. Fig. 5 is a detail view of the spindle.

Similar letters of reference indicate similar parts in the several viewsof the drawings.

Referring to said drawings, the letter A designates the spindle,connected to or formed integrally with the part A, by which it is supported and rotated, said spindle constituting the inner part of the arbor upon which slide thesemitubular sections B and B, hereinafter described. This spindle A is practically round, and at diametrically opposite sides and running longitudinally thereof are formed ribs a, while in the sides intermediate said ribs are formed dovetailed grooves a.

body portion of the spindle tapers gradually toward its outer end, while the diameter through the ribs remains the same throughout the length of the spindle, so that the depth of the ribs gradually increase with the taper of the body portion. These ribs also taper in widthtoward the outer end of the spindle, and the same in connection with the tapered body portion provide for reducing the size of the arbor, as hereinafter eX- plained.

. The semitubular sections B and B are provided at their inner ends with ears I), by which they are pivoted to a sleeve 0, forming the means for sliding said sections upon the spindle. The pivot-pins pass through slots 1) in the ears, and these slots permit movement of the sections to and from each other. Upon the inner side of the semitubular sections and centrally thereof are longitudinal dovetailed ribs or tongues bZwhich are adapted to slide in the corresponding grooves ct in the spindle when the parts are assembled. The semi tubular sections B and B gradually increase in thickness to their outer ends corresponding with the taper of the spindle, so that when the parts are arranged for winding paper thereon, as in Figs. 1 and 2, a solid round arbor is formed, the surfaces of the semitubular sections being flush with the outer surface of the ribs. In practice the surface of the arbor is slightly corrugated, so that 'the paper will catch and hold thereon. After a tube is formed and in removing the same from the arbor the semitubular sections B and B are slid outward upon the spindle A, and in this movement the said sections are drawn toward each other, owing to the taper 0f the spindle, thereby reducing the size of the arbor or part thereof carrying the tube and freeing the tube therefrom. In the out ward movement of the tube with the semitubular sections the said tube slides longitudinally over the ribs a and is disengaged therefrom, and the semitubular sections being drawn toward each other away from the inner side of the tube the latter'may be readily removed.

, It will be seen that the semitubular sections are held inslidable en gagementwith the spindle by means of the dovetailed tongues and grooves in connection with the ribs a,

whereby the parts are securely and firmly connected and the semitubular sections held closely against the tapered spindle in their movement back and forth thereon; also, that when the tube is being formed by winding the paper on the arbor the latter presents practically a solid arbor.

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

1. An arbor for paper-tube machines, con1- prising a tapered spindle, semitubular sections slidable thereon, and dovetailed tongues and grooves for connecting the parts slidably together. 2. An arbor for paper-tube machines, comprising a tapered spindle, ribs formed on the spindle and extending longitudinally thereof, semitubular sections mounted on the spindle between the ribs, and means for holding said sections against the spindle between the ribs as they are slid back and forth thereon.

3. An arbor for-paper-tube machines, comprising a tapered spindle, longitudinal ribs formed thereon and tapered in width corresponding therewith, semitubular sections mounted on the spindle between the ribs, and means for holding said sections against the spindle as they are slid back and forth thereon.

4. An arbor for paper-tube machines, comprising atapered spindle having longitudinal ribs tapered in width corresponding therewith, and semitubular sections slidably mounted on said spindle between the ribs and connected to said spindle by dovetailed tongues and grooves.

5. An arbor for paper-tube machines, comprising a tapered spindle having opposite longitudinal ribs the outer surfaces of which are parallel to each other, said ribs being tapered in width corresponding with the spindle, semitubular sections slidable upon the spindle between the ribs and connected to said spindle by dovetailed tongues and grooves.

63. An arbor for paper-tube machines, comprising a tapered spindle, having opposite longitudinal ribs tapered longitudinally, semitubular sections slidably mounted upon the spindle between the ribs and connectedthereto by dovetailed tongues and grooves, and a sleeve to which said semitubular sections are pivoted, the pivot-pins passing through slots in said sections, substantially as shown and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
