Application filed January 27, 1917. Serial No. 145,032.
To all whom it may oncern Be it known that I, EDWARD F. THOMAS, a citizen of the United States, residing at Felts Mills, in the county of Jefferson and State of New York, have invented certain new and usefullmprovements in Clamp- Collars for Paper-Machines; 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.
This invention has for its object to provicle an adjustable clamp collar adapted to be applied to the winder shaft of a paper machine to efiectively prevent the paper from slipping endwise on the winder during operation.
With this and other objects in view, the invention consists in the novel construction, combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:
Figure 1 represents a fragmentary side elevation of a paper machine, illustrating the invention applied to use,
Fig. 2 represents a transverse sectional view through the winder shaft, showing the clamp collar partly in section,
Fig. 3 represents a detail sectional view at right angles to Fig. 2, and V Fig. 4 represents a perspective view of one of the locking elements of the clamp collar detached.
Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates a sleeve or bushing having a plurality of substantially V-shaped grooves therein defining a plurality of annular ratchet teeth 6. A collar or ring 7 having a plane bore 8 is slidably mounted upon the sleeve 5 and is formed in its outer face with a plurality of radiating grooves 8, extending from the bore to and communicating with the recesses 9 extending transversely across the circumferential edge of the collar.
Portions of the material of the collar on opposite sides of each'recess 9 are cut away, as indicated at 10, to define a pair of outwardly directed cars 11, provided with apertures receiving bolts 12.
A plurality of substantially L-shaped lock-' ing members 13 are pivotally secured by the bolts 14 in the recesses 9, and the latter are so inclined, as indicated at 15, to permit the outer and relatively short arms of the L-shaped members to be swung inwardly to disengage the terminals of the inwardly directed arms from the ratchet teeth 6. The inner terminals of the relatively long arms of the locking members are beveled, as at 16, to snugly fit in the ratchet teeth 6 and lock the collar against outward movement with relation to the roll of paper upon the sleeve 5.
The ends of the transverse recesses 9 adjacent the roll-engaging face 17 of the collar are increased in depth, as indicated at 18, to provide seats for the springs 19, which engage the outer arms of the L-shaped locking members 13, and normally retain the inner terminals of the latter in engagement with the ratchet teeth 6.
In applying the invention to use, the sleeve 5 is slipped over the end of the winder shaft 20 and is engaged with the adjacent terminal of the core 21. The sleeve is held in position upon the winder shaft by sleeves 22, which are held in position by a nut 23, fitted upon the threaded terminal 24 of the winder shaft. The collar is subsequently slipped over the sleeves 22 and inwardly against the adjacent end of the paper roll 25, which is wound upon the core 21. The inner beveled terminals 16 of the L-shaped locking members 13 ride over the inclined faces of the ratchet teeth 6 during inward movement of the collar 7, but effectively lock the latter against outward movement with relation to the paper roll 25. The relatively short outer arms of the locking element constitute handles, which may be pressed inwardly by the fingers of the operator to disengage the inner terminals of the locking members from the ratchet teeth 6 and permit the collar to be slipped outwardly upon the winder shaft 20.
W hat I claim is:
1. In a paper machine, a winder shaft, a core mounted thereon, a sleeve engaged with said core, ratchet teeth on said sleeve, a collar movable longitudinally of said sleeve, and substantially L-shaped locking members pivotally secured to said collar and engaging the ratchet teeth to lock the collar against movement in one direction upon the sleeve.
, substantially L-shaped locking members pivthe sleeve, and means normally retaining 2. In a paper machine, a Winder shaft, a said locking members in engagement with w core mounted thereon, a sleeve engaged with the teeth. the core, ratchet teeth formed on thesleeve, In testimony whereof I affix mysignature a collar movable longitudinally of the sleeve, in presence of two Witnesses. otally secured to the collar and engaging EDWVARD THOMAS the ratchet teeth to lock the collar against longitudinal movement in one direction upon WVitnesses H. J. BUTTS, R. N. NUNEz.
