SPINNING ROLL. APPLICATION FILED JAN-16,1920.

A TTORNE Y JOHN P. CRANE, 01* INDIAN ORCHARD, MASSACHUSETTS.
SPINNING-ROLL.
Specification of Letters Patent.
Patented Dec. 21, 1920.
Application filed January 16, 1920. Serial No. 851,763.
To all whom it may concern:
Be it known that I, JOHN P. CRANE, a citizen of the United States of America, residing at Indian Orchard, county of Hampden, and Commonwealth of'Massachusett-s, have invented certain new and useful Im-- provements in Spinning-Rolls, ofwhich the together by means of a common shaft. This method has been found objectionable for the reason that when it became necessary to change or substitute a new double roll or repair or recover one of the double rolls, it
was necessary to remove both of the double rolls. Another serious objection lies in the fact that should the roving of cotton, or the finished thread, for any reason, become wound around one of the double rolls, it will have the effect of elevating, or raising, the other roll away from the lower roll, or, its mate, thus causing the roving of cotton to pass through, between the rolls, without being properly drawn or spun, resulting in a thread that is not-of the correct size.
The present invention is therefore designed to obviate the above objections, to lessen the cost of manufacture and save time andexpense in making ordinaryrepairs as, for example, in placing a new cover on the roll, or replacing the roll itself.
The invention, broadly. considered, comprises rolls that operate independently of each other and are designed to be retained in place by a common weighting deviceand so that each roll can be readily removed from the machine without disturbing the one adjacent thereto and .located in axial alinement therewith should it become necessary to recover or unwind a roving or thread of cotton therefrom in case it became broken or otherwise entangled thereon.
Referring to the drawings:
Figure 1 is a plan view of a portion of a spinning machine showing several of the independently supported rolls therein.
Fig. 2 is a front elevational view of Fi 1 showing the means for weighting or hol ing the rolls down, and
Fig. 3 is a detail sectional View of the rolls, on the line 33 of Fig. 1, showing the weighting apparatus.
Fig. 4: isa modified construction showing the use of spring for holding the rollers down.
- Referring to the drawings in detail: 1 designates a portion of the main spinning frame, 2, 3, and 4; bearings for the ends of the upper rolls indicated at 5, 6, 7 8, 9 and 10. Two of the forward driving lower rolls are indicated at 11 and 12.. These rolls are the usual fluted ones. Located back of the rolls 11 and 12 are the usual fluted rolls 13 and 14. The bearings of the upper rolls, 5, 6-, 7, 8, 9, and 10 are supported, as shown in Fig. 8, in the bearing pieces 2, 3, and" 4. They are held in place by means of the bars, 15' and 16, which are interlocked at 15'.
- In order to retain the upper driven rolls inplacc, a weighting device is employed. This comprises a forked shaped member 17 whose upper ends 17"are hookedshaped and extend over the bar 15. The lower end of the fork passes under the weighting lever 18, one end of which is formed with a hook 18' which is attached to an eye-bolt 19. The opposite end of the lever 18 is supported with a weight indicated at 20, as shown.
It will be observed that the bearings or journal ends 5, 6, 7, 8, 9 and 10 are loosely mounted in the bearing pieces 2, 3, and 4, being held in place by means of the pieces 15 and 16, weight 20, and the connections between the weight and the bearing pieces. The roving or thread. of cotton which is being drawn through the rolls is indicated at 21. Should a roving or thread that is being drawn through between the rolls become broken and wound around one of the usual double rolls, it would be necessary to remove the two or one roll to unwind the same. In the present improvement it is only, necessary to remove one of the rolls as 5, without disturbing the others, as would have to be the case where two of the rolls are connected together and on the same shaft which is the present and common ractice in spinning machine construction. 11 that would be necessary to do in the present improvement in case of breakage of thread would be to remove any one of the rolls, as 5, without disturbing the others, and replacing the defective roller by a new one. This operation would be accomplished by lifting placed within a suitable housing 23 having an opening 24 in the top, through which a threaded rod 25 passes having a nut 25 at its lower end. This rod hooks over the lever 18 at one end and its other end is provided with a plate 26 which is located below the spring 22. This spring is an expansion one and serves to hold the rolls down in the same way as the weight 20, already described. The weight 20 is somewhat objectionable on account of its first cost. It will be seen that the spring construction is lighter and more compact than the weight construction, and the tension of the same may be accurately adjusted by means of the nut 19, or if desired, by means of the nut 25 on the lower end of the rod 25.
What I claim is:
l. A drawing roll construction for spinning machines, means for mounting the same, comprising a single roll having bearings only at its ends for supporting the same in the frame of the machine, and independently of the other rolls, whereby each roll may be removed and replaced without removing or destroying the adjustment or settings of the other or adjacent rolls which are located in alinement therewith or directly below the same, as described, and means including a forked yoke member for retaining the rolls in place.
2. In a spinning machine, the combination, of independently operable drawing rolls mounted therein, said rolls being provided with oppositely extending bearing stems, means for supporting the stems in the machine and independently of the other rolls and means for retaining'the upper rolls in place in their bearings including a forkedshaped' rod for the purpose described.
3. In a drawing roll construction for spinning machines, the combination of upper rolls mounted in the main frame for operation independently of each other, means for holding the rolls in operative relation to the usual lower rolls, including a forked rod, a lever to which. the rod is attached, a spring, and means for positioning the lever by varying the tension of the spring. I
4. An upper drawing roll construction for spinning machines, each of said rolls having its bearings located in the main frame and independently of each other, means for retaining the upper and lower rolls in engage ment with each other, said means including a spring, a housing for the same including a forked rod, connecting means between the rolls and the spring, a lever, and means includinga threaded rod passing through the spring and a plate on the rod below the spring, said rod being connected to the lever for placing the spring under tension.
5. In a spinning machine, the combination, of spinning rolls, each roll having a thread engaging surface and bearings at each end for engaging bearings in the frame of the machine, the bearings of each roll being independent of the bearings of the other rolls, means for holding the rolls in place in their bearings including a yoke or forkedshaped rod, a lever to which the rod is con nected, and means for placing tension upon the forked-shaped rod for the purpose described.
