JOSEPH H. SHEARN, OF LEEDS, MASSACHUSETTS.
UP-SPINNER AND TWISTER FOR SILK, 800-.
SPECIFICATION forming part of Letters Patent No. 496,582, dated May 2, 1893.
Application filed April 5, 1892- Serial No. 427,813. (No model.)
To all whom it may concern.-
Be it known that I, JOSEPH H. SHEARN, of Leeds, in the county of Hampshire and State of Massachusettahave invented a new and useful Improvement in Up-Spinners and Twisters for Silk, &c., of which the following is a specification, referencebeinghad tothe accompanying drawings, forming part thereof.
My invention relates to spinning and twisting machines for silk, &c., in which the thread is conducted upwardly from the spindle to a receiving bobbin and wound upon the latter. In such machines, the receiving bobbin is carried by a pivoted hanger which is free to rise and fall with the bobbin, and revolving movement is imparted to the bobbin by afriction wheel or drum, which bears upon the layers of thread upon the former, the bobbin and its hanger rising gradually as the quantity of thread on the bobbin increases.
These machines have heretofore been open to the very serious objection that, when the thread upon the spindle runs out, or the thread breaks, the end of the thread thus released is carried by its twisting motion over one of the heads of the receiving bobbin, and engaging the arbor or gudgeon of the latter commences to wind upon the same, thus forming a button of silk upon the arbor. The difference in the diameter of said button and the silk on the bobbin causes the thread to be drawn from the latter to the former, the thread traveling around the periphery of the head of the bobbin in the same direction as that in which the bobbin is revolved by its friction drum. Such winding up of the thread into a button on the arbor, and unwinding off from the bobbin continues until the trouble is discovered and remedied by the operator, which discovery, owing to the fact that each machine comprises a number of such bobbins, is often delayed for a considerable time. Not only does all of the silk which has thus been wound upon the arbor have to be discarded as waste,
but the time required to disengage it from the arbor, so that the bobbin can be again started, adds very materially to the cost of running the machine. Furthermore, the button, if not discovered in time, becomes so thick as toprevent the bobbin from revolving, whereby the driving drum which continues its movepient, is caused to ohafc the silk upon the bobbin and render it necessary to remove a portion of the latter and discard it as waste. The total loss thus caused by the individual machines in mills employing a number of the machines, amounts to a considerable amount annually.
It is the object of my invention to provide means whereby this waste in material and loss of time in the operation of these machines can be avoided, by providing means whereby the revolving movement of the bobbin will secure the breakage of the thread which has commenced to wind upon the arbor and thus stop such winding movement thereof.
To this end the invention consists in providing the heads of the bobbin with an engaging device or devices to engage the thread drawn over either of said heads and cause sufficient strain thereon to break it, as hereinafter fully described and particularly pointed out in the claims.
Referring to the drawings, in which like letters designate like parts in the several figures, Figure 1 is a side elevation of one of the pivoted hangers for the bobbins, said view also showing a bobbin supported in said hanger, the friction drum for revolving the same, and the spindle from which the thread is drawn. Fig. 2 shows a portion of the hanger, with the bobbin therein, and represents the thread as having commenced to wind upon the arbor of the latter. Fig. 3 is aview similar to Fig. 2, representing the thread as having been broken by the engaging device on the head of the bobbin. Fig. 4 is a front elevation of the bobbin and its driving drum.
The letter a designates the hanger, which is composed of two arms pivoted to the machine frame at their rear ends, as shown at b,
and having a slotted bearing at their front ends to receive the arbor or gudgeon c of the bobbin. The letter (Z designates a friction wheel or drum, the width of which is such as to enable it to project between the heads of the bobbin, and which, by bearing against the bobbin or the thread upon the latter, imparts a steady and uniform revolving movement thereto. The letter e designates the spindle from which the thread is drawn, which is provided with the flier f whereby the proper twist upon the thread is secured. All of these parts are common in what are known as upspinning and twisting machines for silk, said machines comprising a series of said parts arranged side by side.
The letter 9 designates the receiving bobbin, which is usually made of iron, and is usually provided with a central hole to receive the arbor or gudgeon 0, instead of making the latter integral with the bobbin.
As hereinbefore stated, when the thread h which is led from the spindle 6 over a traverse bar to the bobbin, runs off from the spindle, or from any cause is broken, the free end thus released is carried by its twisting movement over one of the heads of the bobbin, and, engaging with the arbor 0, commences to wind upon the latter into the form of abutton m, as represented in Fig. 2. The thread is thus drawn tightly over the head of the bobbin, and travels around said head in the same direction as that in which the bobbin'revolves, as it is drawn from the bobbin and wound upon said arbor.
I have discovered that this source of waste and increased expense in running the machines can be obviated by providing the heads of'the bobbin with an engaging device to engage the thread as it is thus drawn around the periphery of said heads, and cause the breakage of the thread. The particular form of said engaging device is capable of much modification, but I prefer to use that herein shown, consisting of a slight concave depression 92 made in the periphery of the bobbin heads. The thread as it is drawn around the periphery of the bobbin head, drops into said depression, and the continued revolving movement of the bobbin causes sutficient strain upon the thread to break it, as shown in Fig. 3. The thread being so broken, the bobbin can continue its revolving movement indefinitely without further injuryto or Waste of the thread.
At p in Fig. 2 I have shown by broken lines a V-shaped slit or recess in the bobbin head, which will secure the same result as to engaging and breaking the thread, and various other forms of engaging device will readily ing the buttons m from the arbors c, which have heretofore very materially increased the cost of running machines of the kind described, and I also insure the perfect condition of all of the thread which is wound upon the receiving bobbins.
Having thus fully described my invention,
what I claim, and desire to secure by Letters Patent, is
1. The combination with the hangers, driving wheel or drum, and spindle andfiier of an u'p-spinning and twisting machine, of a receiving bobbin adapted to be supported in said hangers and to rest upon said driving wheel or drum, said bobbin having one or both of its heads provided with a peripheral engaging device to engage a thread drawn over said heads from the bobbin to the arbor or gudgeon of the latter, substantially as and for the purpose described.
2. The combination with the hangers, driving wheel or drum, and spindle of an upspinning machine, of a receiving bobbin adapted to be revolubly supported in said hangers and to be driven by said wheel or drum, said bobbin having in the periphery of the heads thereof a depression or recess, substantially as described, whereby a thread extending between said .bobbin and the arbor or gudgeon thereof will be drawn into one of said depressions or recesses by the revolution of the bobbin, and broken.
3, The receiving bobbin for upspinning machines herein described, having its heads provided with a peripheral engaging device to engage a thread drawn over either of said heads, substantially as and for the purpose set forth.
