JOSEPH F. MUMFORD, OF CAMDEN, NEIV JERSEY.

SPECIFICATION forming part of Letters Patent No. 550,799, dated December 3, 1895.

, Application filed Mar h 28, 18 95,

To all whom it may concern:

Be it known that I, JOSEPH F. MUMFoRD, a citizen of the United States, residing in the city and county of QamdemState ofNew J er sey, have invented a new and useful Improvement in Methods of Manufacturing Brushes, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to brushes; and it consists of a novel method of manufacturing the same, in which the bristles, hair, or brushstock employed are interposed between a couple of warps or series of threads or wires, which are unwound from reels in any suitable manner, said warps being stitched transversely as they are unwound after the brushstock has been inserted therebetween, whereby the same is held in position, the stitched portion or web being afterward treated with size or similar material and said web being afterward wound and secured upon a suitable handle, whereby a cheap, serviceable, and durable brush of great utility is produced.

It further consists of novel details of construction, all as will be hereinafter set forth.

Figure 1 represents a perspective view of an apparatus in which the improved method of manufacturing brushes embodying my invention is effected. Fig. 2 represents, on an enlarged scale, a section on line a 00, Fig. 1. Figs. 3 to 5, inclusive, represent perspective views of brush-handles employed in the manufacture of brushes of different shapes.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A and B designate reels which are mounted in suitable standards 0, each of said reels having wound thereon a series of threads or warps D and E, which may be of any desired number and guided in any convenient manner. As the said warps are unwound the bristles, hair, or brush-stock F are fed therebetween in the manner illustrated in Fig. 1, said bristles being guided, supported, and kept parallel by any suitable mechanism, and simultaneously as said warps advance they are stitched transversely at Gr G, thus forming an even and compact web H, said. brush-stock being thus held firmly and rigidly in the desired place.

The web after being stitched is now sized by Serial to. 542,940. (No model.)

the application of glue or similar material thereto, whereby the position of the threads of the warp and the transverse stitching and the bristles relative to each other will .always be unchanged, said web, with the bristles, &c., being new wound upon a suitable handle, thereby forming a brush J, as will be eX- plained, it being understood that the width of the warp or the number of the threads will be proportionate to the width of the ferrule which it may be desired to apply to the finished brush.

In Fig. 3 is shown a portion of a brush-handle K, which is provided with a notch L, in which an end of the web is inserted in the initial step of forming the brush, the depth of said notch to be regulated by the width of the web to be introduced therein. The said brush-handle is then revolved, and when the required amount of the web, bristles, &c., is wound thereon said web is cut off and then secured in place by a ferrule or other suit able means.

In Fig. 4 is shown the preferred handle for constructing a fiat or oval brush, the same consisting of the handle M, which has attached thereto a fiat plate N, of metal or other material, around which the web is Wound, a flat or oval brush thus being formed.

In Fig. 5 is shown a preferred form of handle for making a small brush adapted for small round sash-tools, &c., the same consisting of the handle P, which has a brad or pin Q attached thereto, around which is wound the web to the desired thickness, as before.

The operation is as follows: As the warps D and E are unwound from their respective reels, the brush-stock is inserted therebetween and afterward stitched transversely to the line of movement of said warps and treated with glue or similar material, as stated. The resulting web H is now wrapped around the handle of a brush in the manner described, and when a sufficient quantity of the brush stock has been assembled, as seen at J, to form a brush of the required size the web is cut off and is in readiness to be applied to another handle, said web, brush-stock, &c.,

being held in position on the handle by a ferrule or other similar means, said ferrules to be slightly wider than the warps, as is evident.

It will be apparent that the warps D and E may be composed of threads of cotton, sil 1 wire, or other material, and that the same may be supported and guided in any suitable manner, provision being also made for guiding and supporting the brush-stock. The distance between the rows of stitches will be regulated according to the size and style of the brush required, and especial attention is directed to this feature of my invention, since by it the warps are held together and the brush-stock is kept in place and caused to form a compact web, as stated, the above-described operation it will be noted being continuous, the web being cut off'from each handle after it is wound sufficiently thereon and being then applied to another handle, andso on, the result being a strong, durable, and serviceable brush which will not pull apart and can be produced more quickly thanheretofore by hand.

Having thus described my invention, what I. claim as new, and'desire to secure'bylzetters Patent, is-

1'. That improvement in the art of manufacturing brusl1es,.which consists first, in inserting bristles or brush stock between warps or a series of threads, and second, stitching across said warps at an angle thereto, substantially as described.

2. That improvement in the art of" manufacturing brushes, which consists first, in infacturing brushes, which consists first, in actuating a couple of warps or series of threads,

:se'cond, inserting brush stock between said warps,third, stitching across said warps transversely to the line of movement of the same, thereby forminga' web, fourth, applying size or similar material to said web, fifth wrapping said web around a handle, and means for causing said web to be permanentlyheld in place upon said handle, substantially as described.

4. That improvement in t-heart of manufacturing brushes, which consists,.in inserting; brush stock between warps or series-of threads, stitchingacross said warps, thereby forming a web, applying" size or similar material to said web, wrapping said" web about a handle, and lastly causing said web to be permanently held" in place, substantially'as described.
