EQLLAJR FOR WINDER SHAF'IXS OF PAPER MACHINES.
Application filed March 26, 1925, aerial No. 18,617.
To a?! Irvin m it may concern.
Be it known that .l, JEFF N. LAMAR, a c1t1- zen of the United States, residing at Plercefield, in the county of St. Lawrence and State of New York, have invented certain new and useful Improvements in C0llars for Winder Shafts of Paper Machines, of which the following is a specificatlon, reference being had to the accompanying drawings.
This invention relates to a collar for the winder shaft of a paper machine and 1t 1s an object of the invention to provide a device of this general character with means whereby the same may be effectively held in desired position upon the shaft as the occasions of practice may necessitate.
The invention consists in the details of construction and in the combination and arrangemet of the several parts of my 1mproved collar for the winder shaft of a paper inachine whereby certain important advantages are attained and the device rendered simpler. less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.
The novel features of my invention will hereinafter be definitely claimed.
In order that my invention'may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view partly in section and partly in elevation illustrating a collar constructed in accordance with an embodiment of my invention in applied osition;
Figure 2 is a view simi ar to Figure 1 with the cover in section;
Figure 3 is a sectional view taken radially of the device as herein disclosed with the associated shaft shown in elevation;
Figure 4 is a fragmentary view in spective of the free end portion of one o the jaws herein embodied.
My improved collar, as herein disclosed, comprises a plate or disc 1 of requisite dimensions and which is provided at its axial center with an opening 2 to permit the plate to be readily applied to the winder shaft S. Pivotally connected, as at 3, with the inner marginal portion of the plate 1 are the adjacent end portions of the arouate jaws 4, said jaws being substantially semicircular in form and having their free ends provided with the outstanding ears 5, one
of said ears being provided with an outwardly disposed open slot 6.
The jaws 4 are constantly urged inwardly one toward the other for requisite gripping action upon the shaft S by the relatively heavy spring 7 disposed around the jaws and having its extremities terminating im mediately adjacent to the ears 5. The innor or working faces of the jaws 4 have their side marginal portions defined by the in- .Wardly disposed beveled ribs or flanges 8 adapted to have effective gripping action upon the shaft S under the influence of the spring 7 whereby the applied collar is locked in desired position upon the shaft and held against movement in a direction lengthwise of the shaft. The flanges 8 are tempered to further assure the efliciency thereof.
Pivotally supported between the free ends of the jaws 4 and the outstanding ears 5 is a cam member 9 provided with an operating lever 10 which, when the jaws 4 are in closed or working position, extends through the open slot 6. Upon imposing outward pull upon the lever 10, the cam member 9 will cause the free end portions of the jaws 4 to separate in order to permit the collar to be applied to or removed from the shaft S or to be adjusted lengthwise thereof as desired. When the lever is swung inwardly the tension of the spring 7 will cause the jaws 4 to move inwardly and having requisite holding contact upon the shaft S and maintain such contact.
The jaws 4 together with the spring 7 are preferably housed within a cover C maintained in applied position by the bolts 11 which constitute the pivotal mount for the jaws 4 and cam member 9, said b dlt s being also operatively engaged with the plate 1. The cover G in its axial center is provided with the opening 12 to permit the requisite application of the device upon the shaft S and the peripheral portion of said cover 0 is provided with an opening or cut away portion 14 of a size to permit access to the lever 10 and the requisite operation thereof.
My improved collar can be employed in lieu of the use of rope as now generally done and serves effectually to maintain the paper in proper position upon the shaft. My improved device also reduces to a minimum the liability of accidents, such as etting fingers or hands out off, and it is rther particularly adapted for use in view of the fact that it can be readily and conveniently applied during the period the shaft is running.
From the foregoing description it is thought to be obvious that a collar for the winder shaft of a pa er machine constructed in accordance wit my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departin from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
I claim l. A collar for a winder shaft comprising a plate having a central opening through which the shaft is adapted to be disposed, arcuate jaws pivoted to said plate and disposed around the marginal portion of said opening. a spring member disposed around said jaws and bearing thereagainst to urge the jaws inwardly for 7 contact with the shaft, and means for imparting separating movement to the jaws.
2. A collar for a winder sh-aft comprising a plate having a central opening through which the shaft is adapted to be disposed. arcuate jaws pivoted to said plate and disposed around the marginal portion of said opening, a spring member disposed around said jaws and bearing thereagainst to urge the jaws inwardly for contact with the shaft, and means for imparting separating movement to the jaws, the opposed working faces of the jaws being provided with inwardly disposed biting flanges for direct engagement with the shaft.
3. A collar for a winder shaft com risin f a plate 'havin a central opening tiirougi which the sha t is adapted to be disposed, arcuate jaws pivoted to said plate and disposed around the marginal ortion of said opening, a spring member dlsposed around said jaws and bearing thereagainst to urge the jaws inwardly or contact with the shaft, and means for imparting separating movement to the jaws, the opposed working faces of the 'aws being provided with inwardly disposed biting fla es for direct engagement with the shaft, said flanges being arranged along opposite sides of said working faces of the jaws.
4. A collar for a winder shaft comprising a plate having a central opening through which the shaft is adapted to be disposed, arcuate jaws pivoted to said plate and disposed around the marginal portion of said opening, a spring member disposed around said jaws and bearing thereagainst to urge the aws inwardly for contact with the shaft, a cam member pivotally supported by the plate between the free end portions of the aws, and an operating member for said cam, rotation of the cam in one direction im arting separating movement to the jaws.
n testimony whereof I hereunto afiix my signbature.
JEFF N. LAMAR.
