Description
Sept. 20, 1932. w. H. FURNESS DRAWING WHEEL Filed Jan. 11, 1929 ATTORNEYS Patented Sept. 20, 1932 UNITED STATES NT FFIcE WILLIAM FURNESS, OF NATIONAL PARK, NEW JERSEY, ASSIGNOB 0F PHILADELPHIA, PENNSYLVANIA,
CORPORATION, \TERSEY TO FUBNESS DRAWING- WHEEL I Applicatilin filed was 11,1929.v s r iarno. 331,781.
This invention relates to drawing wheels and is particularly useful in the manufacture of artificial silk thread.
In my copending application Serial No. 239,401, filed December 12, 1927, I have shown and described a drawing mechanism comprising two vertically separated draw ing wheels over which the thread as formed in the bath is serially passed and from which the thread is led to the cap twister mechanism shown and described in my copending application Serial No. 239,403, filed December 12, 1927. In the specific arrangement shown in the drawings of the first mentioned application the drawing wheels are of different diameter, but driven at the same speed,
in consequence of which the thread is stretched in passing over the drawing wheels, or, more properly speaking, the drawing wheels serve to remove the extensibility of the thread incident to the structure which results from the precipitation of the cellulose solution in the bath, in contradistinction to what is ordinarily known as stretch spinning.
The present invention consists in an improvement upon such drawing mechanism, and one of its primary objects is to provide a more simple and compact drawing mecha nism and upon which the thread may be started with great facility.
Another ob ect of the invention is to provide a drawing mechanism which makes it possible to make the spindle more compact 2nd to simplify the driving mechanism thereor. v
I accomplish the foregoing, together with such other objects and advantages as may hereinafter appear, or are incident to my invention, by means of the construction which I have illustrated in the preferred form in the accompanying drawing, where- 1n- Fig. 1 is a vertical section through a portion of a spindle housing illustrating the improved drawing mechanism in side elevation, and
Fig. 2 is a horizontal section with the drawing mechanism in top plan view.
Referring now to the drawing, the reference numeral? indicates the spindle housing forming part of the invention of my application .SerialfNo. 331,799, filed January 11,
.1929. 111 the upper portion of the housing are the drawing wheels wheels being mounted on 8 and 9; these two the-shaft 10 driven in any suitable manner. Pinned tothe free end of the shaft 10 is a collar 11 preferably provided with ratchet teeth 12 on its inner face. A similar member 13 is provided on the hub portion of the wheel 8. The two wheels 8 and 9 are nonrotatably carried on the shaft 10, but are normally pressed outwardly by the spring 14 so that the members 13 and 12 are engaged to provide a driving connection between the wheels and the shaft. The wheels are preferably formed integrally or otherwise arranged so that both shall be driven when the parts 13 and 12 are in engagement.
The two wheels are of different diameter, and the thread, as it comes from the bath, passes over the guide 15, thence around the smaller wheel 9 and through the eyes 16 and thence around the wheel 8 over the guide 15, and again around the wheel, the thread then leading to the cap twister mechanism not shown. The foregoing arrangement of the wheels imparts to the thread the stretch hereinbefore described.
When a spool is filled, the operator merely presses the wheels inwardly against the pressure of the spring to disengage the driving connection. And similarly, if, for any reason, the thread is not being wound upon the spool and is accumulating on the drawing wheels. The thread is, of course, started with the wheels rotating.
It will be seen that the drawing mechanism is simple, and that it is easy to start- A conrona'rron or new the thread. It is not necessary to stop the spindle operating mechanism when dotting aand the like to expose both wheels, and thus enable an operator to observe the operating condition of the spindle from the exterior.
I claim 1. Drawing means for artificial silk thread comprising two wheels of dif ferent diameter, and a drive shaft on which the wheels are mounted to be driven thereby, and means whereby the thread is laid first around one wheel and then around the other.
2. Drawing means for artificial silk thread and the like comprising two wheels of different diameter, a drive shaft on which the wheels are non-rotatively carried, clutch means providing a driving connection therebetween, and guide means whereby the thread is laid first around one wheel and then around the other.
3. Drawing means for artificial silk thread and the like comprising two wheels of different diameter, a drive shaft on which the wheels are non-rotatively and slidably .carried, clutch means on the wheels shaft adapted to provide driving engagement therebetween, and spring means normally holding the clutch means .in engagement, and guide means whereby the thread is laid first around one wheel and then around the other.
4. Drawing means for artificial silk thread and the like comprising two wheels of different diameter located side by side and having substantially the same axis of rotation, means for rotating the wheels, and means whereby the thread is led first around one wheel and then around the other.
5. Drawing means for artificial silk thread and the like comprising two wheels mounted side by side, means for rotating said wheels, and guide means whereby the thread may be led to one wheel and then to the other.
In testimony whereof I have hereunto signed my name.
WILLIAM H. FURNESS.
