FABRIC ROLL.

Application filed July 3, 1925. Serial No. 41,265.

My invention relates to a new and improved fabric roll for polishing and cleans ing purposes and for removing and applying all substances such as powders, pastes and the like.

One of the objects of my invention is to provide a fabric roll which shall be especially adapted to be used for small size bufiing wheels.

Another object of my invention is to provide a fabric roll which can be used for applying powders, such as a powder putt, for cleansing and removing powdered materials, such as a blackboard eraser, or for applying and removing all paste and liquid materials such as shoe polish, paint, and the like.

Another object of my invention is to devise a fabric roll which shall utilize the spirally wound end surface of a strip of bias-cut tape. Whenever I refer to bias cut tape herein, I refer to a strip of fabric formed by,cutting a sheet of said fabric in a direction diagonal to both the warp threads and the weft threads, so that the threads in said strip are diagonal to the length thereof.

Other objects of my invention will be set forth in the following description and drawings which illustrate preferred embodiments thereof, it being undeistood that the above general statement of the ob ects of my invention, is intended to generally illustrate the idea and not to limit it in any manner.

Fig. 1 is an elevation of one embodiment of my invention, the view being partially in section.

Fig. 2 is a sectional view partially in section illustrating another embodiment of my invention.

Fig. 3 is a perspective view showing another embodiment of my invention.

The fabric roll 1 shown for example, in Fig. 3, consists of a spirally wound roll of bias-cut tape. The various layers or the windings of the said roll, can be held together by an suitable means. For example, in the embo iment shown in Fig. 1, one end of the 'roll is thrust firmly into a. metal cup 2 in which the roll 1 fits tightly so that no other means are required to'hold together the layers or windings of the roll 1. In the embodiment shown in Fig. 2, a wire staple or staples t are thrust laterally through the various layers or windings of the roll 1. .In the embodiment shown in Fig. 3, an ordinary pin 7 serves to hold together the outer layers of the roll 1 and in the embodiment illustrated in Fig. 6, the various layers of the roll 1 are held together by lateral stitches 10.

The embodiment shown in Figs. 1 and 2 is especially adapted to be used for butting, polishing and cleaning surfaces or for ap plying powdered or pasty or other materials to said surfaces.

In both said embodiments, the flat face of the bias-cut tape is not utilized for said pur poses, but the spirally wound edge of the bias-cut tape is utilized.

Considerable difliculty has been found heretofore in making bufling wheels of small sizes, but according to this invention, biascut tape can be formed into a spiral roll of any desired diameter, the width of the rollbeing equal to the width of the strip of tape.

The fibrous edges of the layers of tape form a soft yielding surface which is especially suitable for the above mentioned purposes. The advantage of using bias-cut tape is that the fibres are all inclined to the free lateral face of the roll, so that the fibres are held together with maximum strength and they are not readily pulled out when the roll is used. In addition, the layers of the roll of fabric made according to my inven tion touch each other at the free lateral face thereof and each layer of fabric is Wound or bent about a, single axis, which further increases the durability of the device.

When the device is used, the edges or periphery of the roll of tape, tend to be forced backwards so that the polishing end of the roll tends to assume a more or less conical or bullet shape. The strip of tape used to make the roll can be tapered.

In the embodiment shown in Fig. 1 and as further illustrated in Fig. 3, the roll of tape is solid, that is, the tape is not wound about a core or the like. In the embodiment shown in Fig. 2, the tape is wound about a hollow core 5 and this is connected to the threaded extension 6 of the shaft 3 by means of a nut 9.

While I have hitherto spoken of forming the roll of tape from a strip of bias-cut tape, I do not wish to be limited to the use of this material as my invention covers any woven material having the weft and warp threads inclined to the lateral face of the roll and although I have mentioned some of the uses for which a roll of this type is principally used, I do not wish to be understood as limiting my invention in any manner or to any specific use or uses.

Rolls of biascut tape, as heretofore sold at notion counters, etc., have had both edges of the tape folded inwardly. However in the roll of bias-cut tape made according to my invention, the edges of the tape remain unfolded so that the loose ends of the threads of the tape are free to take up all materials.

In order to utilize a roll of bias-cut tape for a powder pufi, I have 'found it preferable to wind the said roll of tape in spiral form around a core and then remove the core and flatten the roll of tape until its cross-section is substantially elliptical. The roll of tape can then be maintained so as to have the said elliptical contour by means of a sewing operation, glue or the like.

Instead of formingthe roll of bias-cut tape from a single piece of tape, I have also found it advantageous to take a number of pieces of tape which may be of approximately equal length or of varying lengths, wind the said pieces of tape into spiral form, while the said pieces are superposed one above the other-with the ends forming the inner portion of the roll of tape preferably adjacent each other and to stitch together the various layers of the spiral roll thus formed as the various layers are formed and before the roll is finally completed. The advantage of this is that the cylindrical exterior of the roll of tape has the ends of the said strips arranged in regular spaced relationship so that not onl the end face of the roll but also the cylin rical face thereof can be utilized for the purposes above mentioned.

Another advantage of this last mentioned construction is' that the roll is not entirely dependent upon, a single layer or row of stitches.

I have shown a preferred embodiment of my invention, but it is clear that numerous changes and omissions could be made without departing from its spirit.

I claim An end face bufier comprising a roll of bias-cut fabric tightly wound into spiral form, the layers of the spiral roll thus formed being in intimate annular contact throughout, and a spindle connected with one of its end faces.

In testimony whereof I affix my signature.
