BOBBIN-CLEANING DEVICE.

Specification of Letters Patent.

Patented Apr. 7, 1914.

Application filed November 6, 1913. Serial No. 799,432.

To all whom it may concern:

Be it known that I, JosnPI-r F. VAILLAN- COURT, a citizen of the United States, and residing at Fall River, in the county of Bristol and State of Massachusetts, have mvented certain new and useful Improvements in Bobbin-Cleaning Devices, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to what are known as bobbin cleansers, whereby what are known as thread stubs may be quickly and easily removed from a shuttle bobbin without ury thereto, and so that the bobbin may be rewound with thread.

In the operation of the shuttles of looms, the thread, when partially exhausted from the bobbin, frequently becomes stuck thereon or locked so that it will not unwind. The amount of thread on the bobbin at this time, is called a stub and this stub must be removed before the bobbin can be rewound with thread. Hereto-fore, it has been customary to cut through the stub longitudinally of the bobbin with a sharp knife so as to remove the stub from the bobbin, but this frequently results in injuring the bobbin. It has also been customary to grasp the stub and bobbin in the hand and then strike the smaller end of the bobbin on the loom frame, or any other object, a number of times, which operation would result in sliding the stub off of the bobbin, but this operation is difficult and.

frequently ineffectual, and the object of this invention is to provide a device of the class specified which is simple in construction and operation, and by means of which a stub may be quickly and easily removed from a bobbin, without injury to the latter.

The invention is fully disclosed in the following specification of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the Views, and in which Figure 1 is a side view of a shuttle bobbin provided with a stub of thread Fig. 2 a longitudinal section of my improved device for removing the stub from a bobbin Fig. 3 is a view similar to Fig. 1 and showing the method of using my improved bobbin cleaner, and Fig. 4 a cross section on the line l-l of Fig. 2.

In the drawing forming part of this specification, I have shown at a an ordinary shuttle bobbin such as is used in all looms, and the bobbin a is provided at its larger end with a head a and the bobbin shown is provided adjacent to the head a thereof with a stub Z) of thread.

In the use of bobbin shuttles of the class specified, after the thread wound thereon has been partially used, the thread frequently catches or becomes fastened in some way so that it will not unwind, and this forms what is called a stub, as shown at Z), and it-is necessary to remove this stub from the bobbin before the bobbin can be rewound. The device which I employ for this purpose'is shown at 0 in Figs. 2, 3, and 4:, and is tubular in form in cross section and larger at one end than at the other, the smaller end being provided, in the construction shown, with an annular head 0 The bobbin cleaner 0 from the head 0 to about the middle thereof is preferably of the same size, but from about the middle thereof to the opposite end, the said bobbin cleaner is enlarged, this enlargement being a gradual taper, in the form of construction shown, from the said end toward the middle of the device. The bobbin cleaner 0 is divided centrally and longitudinally into two similar parts 0 and the opposite sides of the enlarged end thereof are provided in the plane that separates the parts thereof, with longitudinal V-shaped recesses 0*, and one part is preferably provided with longitudinal flanges o in which the side edges of the other part fit.

An elastic band or retainer d, of any kind or construction, is passed around the smaller end of the device adjacent to the head 0 for the purpose of holding the separate parts together and in operative position.

From the foregoing description, it will be seen that my improved bobbin cleaner consists of two jaw members, yieldingly connected and into or between which a bobbin with a stub of thread is adapted to be inserted, and the use of this device in removing the stub Z) from the bobbin is indicated in Fig. 3, and in this operation, the cleaner is slipped on over the smaller end of the bobbin and onto the stub Z), and the larger end of the said cleaner is grasped in the hand and pressure is applied thereto so as to cause the larger end of the cleaner to grasp and hold the stub, while the smaller end thereof, or the side portions thereof are separated and free from the body of the bobbin, and the smaller end of the bobbin is then struck a number of times on the frame of the loom, or any other object, and in this operation, the stub is slid off of the bobbin which may be rewound in the usual manner.

The inner walls of the bobbin cleaner are preferably provided with annular ribs, teeth or projections c, and in the construction shown, the said inner walls are tapered from one annular rib, tooth or projection, to another, but this exact construction is immaterial, and the said inner walls of the cleaner or the separate parts thereof may be provided with'any kind or class of inwardly directed teeth or projections in order to fa-' cilitate the grasping and holding of the stub b, as shown in Fig. 3, and while I have shown and described the preferred form of my improved bobbin cleaner, my invention is not limited to the details of con: 'struction herein shown and described, and various changes therein and modifications thereof may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing. its advantages.

Having fully described my invention What Iclaim as new and desire to secure by Letters Patent is V 1. A hand operated bobbin cleaner comprising two oblong jaw members between which a bobbin with a stub of thread is adapted to be inserted, said jaw members being concavo-convex in cross section and adapted to be grasped by, held in, and operated by one hand, and to be compressed on said stub of thread. 7

2. A hand operated bobbin cleaner comprising two similar jaw members between which a bobbin with a stub of thread is adapted to be inserted, said jaw members being provided in their inner faces with longitudinal grooves, and being also tensionally connected at one end.

3. A hand operated bobbin cleaner of the class described, said cleaner being tubular in form in cross section and being composed of two similar aw members between which a bobbin with a stub of thread is adapted to be inserted, said jawmembers being tensionally connected at one end.

4a A hand operated bobbin cleaner of the class described, said cleaner being tubular in form in cross section and being composed of two similar jaw members between which a bobbin with a stub of thread is adapted to be inserted, said jaw members being tensionally connected at one end, and being separated at the other end by V-shaped recesses. 5. A device of the class described which is tubular in form in cross section and of predetermined length and larger at one end than at the other, said device being divided centrally and longitudinally into separate similar parts, and the separate parts atthe larger end being separated by longitudinal V-shaped recesses.

6. A device of the class described which is tubular in form in cross section and of predetermined length and larger at one end than at the other, said device being divided centrally and longitudinally into separate similar parts, and the separate parts at the larger end being separated by longitudinal V-shaped recesses, and said parts being provided at the smaller end with a yielding con nection.

7. A device of the class described which is tubular in form in cross section and of predetermined length and larger at one end than at the other, said device being divided centrally and longitudinally into separate similar parts, and the separate parts at the larger end being separated by longitudinal V-shaped recesses, and said parts being provided at the smaller end with a yielding connection, and the inner walls of said parts being provided with inwardly directed projections.

In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing witnesses this third day of November 1913.
