Specification of Letters Patent.
Application filed August 12, 1912.
Patented Sept. 2, 1 913. Serial No. 714,643.
To all whom it may concern Be it known that I, FRANK E. Knrns, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State 017' California, have'inventcd certain new and useful Improvements in \Vinding Rolls or Formers for Paper-Pulp Tubes; and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in winding rolls or formers for paper pulp tubes, the object being to provide the roll with a simple and inexpensive attachment for quickly detaching the adhering pulp tube, and it consists in a cam mounted in a groove in the periphery of the roll and adapted when turned to slightly distend the pulp tube and admit air between it and the surface of the roll.
My invention further consists in the parts and combination of parts, and in the details of construction as will be more fully described and pointed out in the claims.
In the accompanying drawings, Figure 1 is a view in perspective of a roll embodying my invention; Fig. 2 is a view in longitudinal sect-ion through same on line mw of Fig. 3; Fig. 3 is a view in transverse section and Fig. 4 is a view of a modified form.
The winding roll preferably comprises a cylinder 1., having end spokes 2, and hubs 3, preferably integral and if desired there may be spokes and hub sections intermediate the end spokes and hubs, or the spokes and hub may be continuous throughout the length of the cylinder. The cylinder 1 is provided in its periphery with a groove 3 formed in the arc of a circle, and extending throughout the length of the cylinder for the reception of the cam i which extends through out the length of the groove 3 and is adapted to turn therein. A part 5 of the surface of this cam 4 is concentric with the periphery of the cylinder, so as to form a smooth, continuous unbroken surface therewith, while the remaining portion of the cam conforms in shape and size to the are shaped groove 3, and is concentric with the axis of the cam, so that when the cam is turned or partly rotated, the concentric portion will project above the periphery of the cylinder. The portion of the cylinder having the groove therein is thickened as shown so as to house the groove, and the portion of "the cylinder diametrically opposite the groove is also thickened so as to balance the cylinder.
The cam is provided at one end, or at both ends it desired, with a handle 6 by which it may be wholly. or partly rotated. This handle is preferably made slightly flexible so that it may be disengaged from a lug 7 integral with the cylinder, and which when the cam It is in its normal position, shown in Fig. 1, enters a slot or notch 8 in the handle. lily pulling outwardly on the knob 9 of the handle 6, the latter will be disengaged from the leg 7 and is then free to be turned. The handle 6 is provided with an angular projection 10 which latter enters a similarly shaped recess in the end of the cam and is locked therein by the screw or pin 11, and the cam is prevented from lon gitudinal movement with the groove by the screw 12, which enters the peripheral groove 13 in the cam preferably near one end of the latter.
The construction shown in Fig. 4., is substantially identical with that shown in the other figures, except, that the roll is made solid with trunnions 1 1- intcgral with the roll. I prefer to make the smaller sizes solid, and the larger sizes hollow as in Fig. 1.
In the operation of the roll, after the pulp tube has been deposited thereon in the well known manner, the operator turns the handle and rotates the cam 4, thus carrying the portion thereof which is concentric with the axis of the cam above or beyond the periphery of the cylinder 1. This movement of the cam distends the tube, and dis engages it from the cylinder 1 at the sides of the groove 3 and permits air to enter between the pulp tube and the cylinder. By now pressing slightly against the distended portion of the tube the air will be forced around the cylinder within the pulp tube, thus loosening the latter and permitting it to be readily withdrawn endwise. After the pulp tube has been loosened and before its removal, if desired, the operator turns the cam back to its normal position.
It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to periphery with a longitudinal groove arc.
shaped in cross section, and a rotating cam moui'ited in said groove, the said cam having a portion of its surface conforming to the curvature of the periphery of'the cylinder and the remaining portion adapted when turned to project beyond the periphcry of the cylinder.
' 2. A winding roll for forming paper pulp tubes, comprising a cylinder provided in its periphery with a longitudinal groove are shaped in cross section, a rotating cam mounted in said groove and extending approximately the length of the cylinder, the said cam having a portion of its surface conforming to the curvature of the periphery of the cylinder and the remaining portion in the arc of smaller radius so that when turned will project beyond theperiph- 'ery of the cylinder.
8. In a winding" roll for forming paper conforming to pulp tubes, the combination of a cylinder provided in its periphery with a longitudinal are shaped groove, a rotating cam in said groove, the said cam having a portion the curvature of the periphery of the cylinder and the remaining portion conforming to the curvature or the v groove within which it is mounted, means for locking said cam within the groove and a handle for rotating the cam.
4. The combination of a cylinder having an are shaped groove in its periphery, the said groove extending lengthwise the cylinder, a rotating cam mounted in said groove, 7
the said cam having a portion of its surface conforming to the curvature of the periphery of the cylinder and the remaining port'io'n adapted when turned to project beyond the periphery of the cylinder, a handle secured to said cam at one end, and means for looking the cam against endwise movement. In testimony whereof, I have signed this specification in the presence of two subscribing witnessea Y FRANK E; REYES.-
