- Application filed may 31 Toall wkom it may concern:
Be it known that I, GLAnK T. Hnnonnson,
'a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Winding Mechanisms, of which the following is a full, clear, concise, and exact description, reference be-' inghad to the accompanying drawing forming a part of this specification. I
Thisinvention relates to winding mechafnisms, particularly applicable to paper mills for rewindin purposes but also susceptible of various ot er u ses. I Heretofore rewmdmg has been accomf plished by placing the mandrel upon which the paper is to be wound upon and between provide automatic means for efi'ecting retwo rollers located closely together and revolved in the same dllGClllOll, the paper suppliedto the mandrel being passed around one of said rollers. This method of rewinding has been found very satisfactory, but
owing to the varying wei ht and other conditions of the rewound ro it has been found necessary, or at least desirable, to vary'the relative speeds of the two winding rollers and heretofore such speed regulation has been accomplished by adjustment of a me: chanical speed changing device.
This invention has among its objects to winding according to the above described method. p
A further object is to provide a winding mechanism of the character mentioned with means to effect variation in the relative speeds of the two rollers according to the weight of the rewound roll. A'still further object is to, provide such an automatic'windin mechanism with means I to brake either ro ler to thereby retard the speed thereof and at the same time accentuatethe speed of the rollernot so braked.
. Other objects and advantages of thednvention'will hereinafterappear. I

, ie c. Serial no. 100,803.
Fig. 3 is a diagrammatic view exemplifymg the method of rewinding. he mechanism illustrated includes rollers 4 and 5, a driving motor 6 and driving connections between said motor and said rollers including a diiferential gear 7. exemplified in the diagrammatic view (Fig.3) the rollers 4 and 5 are provided to support a mandrel 8 upon which is to be re- 5 wound the stock of a roll 9. The rollers 4 and 5 are arranged to be driven counterclock'w1se to thereby rotate the mandrel 8 in a clockwlse direction, the paper from roll 9 being passed to the mandrel 8 around the roller 4. Thus it will be observed that as the rollers 4 and 5 are rotated they will-tend to transfer the paper from roll 9 to mandrel 8. Also, it will be observed that when the mandrel is light it will tend to follow the per1phery of roller 4 and in so doing revolve away from roller 5 whereas, when the weight of the'mandrel increases such tendency will be gradually eliminated. Thus to insure proper tensioning of the paper on the mandrel it is desired to initially drive the roller 5 at a greater peripheral speed than the rolle'rA and to gradually equalize the speeds of the two rollers as the weight of the mandrel increases. 1
The mechanism shown in Figs. 2 and 3 provides-for such speed adjustments automatically. The shafts of rollers4 and 5 are respectively provided with pulleys 4 and 5 connected by belts 10 and 11 to pulleys 12 and 13 driven b members of the differential gear. The di erential gear .is 'of conventional form and includes two loose inions 7 and 7 respectively connected to t e'pulleys 12 and 13. The pinions 7 and 7 mesh with intermediate pinions 7 carried .by a quill 7 d keyed or otherwise fixed to the shaft 6 of the driving motor. observedthat as'the quill is revolved it will tend to revolve both pinions 7 and 7 in the same direction to thereby revolve the rollers 4 and 5 in the same direction.
Considering the operating conditions it 'groller 4, impose arelatively greater load upon said rcll'er than upon roller 5. In other] Thus it will be will beobserved that when the mechanism is started with a light mandrel, said mandrel will, asa result of its tendency to followlos words, the roller 4 will under such condii and in consequence thediiferential drive will of roller 5 over that of roller 4, the result desired." On 'the other hand, as the weight of the mandrel increases in the effect a corresponding increase in the speed this being progress of the rewinding operation with a resultant tendency of the mandrel to settle back on roller 5, the increased resistance thus offered to roller 5 will tend to effect equalization of the speeds of the two rollers through the differential gear. Thus in a word, the difl'erential gear provides for offset initial speeds and gradual equalization of speeds as the rewound roll increases in size and weight, so that when the rewinding operation is completed the rollers 4 and 5.
' ening the brake 15 a reverse result may be obtained.
What I claim as new and desire to secure by Letters Patent is:
1. A winding mechanism including supporting rollers for a winding mandrel, said rollers being subjected at all times to a load substantially proportional to the amount of material on the mandrel and driving means for said rollers including means rendering the latter sensitive to variations in the load thereon for automatic and inversely proportional variations'in their speeds.
2. In a winding mechanism, the combination with rollers to support a winding mandrel, of means to drive said rollers at different speeds for initial operation of the mandrel and to increase the speed of one of said rollers and decrease the speed of the ogher of said rollers automatically therea ter.
3. In a winding mechanism, in combination, supporting rollers for a Winding mandrel and driving connections therefor including a differential gear to vary the speed ratio of said rollers automatically.
4. In a winding mechanism, in combination, supporting rollers for a winding mandrel, power driving means for said rollers and differential driving connections between said means and said rollers to ofiset the speeds. of said rollers for initial rewinding operation and thereafter tending to equalize the speeds of said rollers.
5. A winding mechanism including supporting rollers for a Winding mandrel, driving means for said rollers including means rendering the latter sensitive to variations in the load thereon for automatic and inversely proportional variations in their speeds and means for varying the speed ratio of said rollers at will.
6. In a winding mechanism, in combination, rollers for supporting a winding mandrel, driving means for said rollers tending to establish a speed ratio therefor Varying with the working conditions and independent adjustable braking means for said rollers.
.7. In a winding mechanism, in combination, rollers for supporting a winding mandrel, means for driving said rollers difit'erentially and means to brake said rollers selectively.
8. In a winding mechanism, in combination, rollers for supporting a winding mandrel, means for driving said rollers difi'er- .entially and separately adjustable brakes for said rollers. I
In witness whereof, I have hereunto subscribed my name.
