Patented Feb/1, 1908.

To all whom 'iilmay concern: Be it known that I, PHILIPPE CHAZAL, a

manufacturer, and a citizen of the French Republic, residing at Lyon, France, have invented certain newand useful lmprovements in the Manufacture of Brushes,;of

' which the following isa specification.

This invention relates to improvements in the manufacture of b ushes, and the ob'ect is'to produce such articles having a soli fty hitherto unknown by wrapping the tuft or tufts of bristles or the like m a spirally rolled up band of metal or other suitable material views partly .in section showing various forms of application of the invention to a --paint brush. Figs. 6, 7 and 8 are elevations such as pa er, leather, cardboard, independent from t e handle.

In the annexed drawing Figures 1 to 5 are showing the b and to which the bristles are applied before rolling. Fig. 9 is a section on line-9+9 of Fig}; Fig. 10 is asectionon line 10- -10 of 5. Figs. 11 and 12 are cross-sections showing two other forms 'of "the band after rolling or bending and pressure, and Fig. 13 is an elevation of a band 1 an undulating havmg narrower superposed, bandswhich after rolling permit-0f giving the outer band form to prevent removal of thebristls;

The formation'of the'brushes according to this invention is effected inthe following manner: I take a band A of thin metal,

ilinen, felt, cardboard or the like which may be com ated, grooved, molded or provided with sma perforations B produced by stampto es of the'material ce o the band numerous projections B are formed. This band Ai is then cut out in such a manner as to have an enlargement A at or adjacent one of its ends.

- The bristles or similar material for forming .the brushare spread over the band A u to the enlargement A which must be left ree, whereupon said band is rolled upon itself beginning at the narrow end, to which, for the purpose of giving eater hold to the I gptirator, is fixed a smal metal stem or tube or instan either by soldering as shown in F1g. 6; b a saw-slit C as in Fig. 7; by a mortise all tenon C C respectively as in Fig. 8, or by any other convement means.

The sald stem C being of metal, is adapted to become flattened during rolling or compression. When such a stem is used it is given a very small diameter in order not to form an empty space in the center of the brush, and the part of said stem which engages the handle A is given a flattened-or angular form as at' C? to prevent rotation thereof, and is rovided with a pointed end C in order to acilitate its enetration into the wood of a handle. ter rolling, the stem may be either left in the tuft of bristles, or if loosely attached as in Fig. .7, it may be removed therefrom.

The rollin up of the band A about the stem C may e effected whether the stem'C has been previously secured to a handle or maybe exerted on'the band with a tool of suitable sha e for the purpose of producing therein 'ann ling or seriesof grooves for increasing the rigidity of connection of the bristles (see Figs. 3 and 4). .When the rolling is finished the enlarged part A of the band forms aferrule extending beyond the butts of the bristles and the remainder of the band, and adapted to surround the 'end of the handle forsecuringthe brush thereto (see Figs. 2, 3, 4 and 5). The connection of the handle to said ferrule may be effected in any suitable or known manner. After having rolled the band, the various layers or convolutions thereof are connected together by means of nails D (Fig. 5), whereupon the' band is compressed in a inold of the form of a truncated cone.

I may previously insert into that part of the ferrule into which the handle is to be fixed a solid material adapted to melt at a temperature above 100. This material is first melted, then compressed in the 'ferrule in which it soon fills any existing interstices. The butts of the bristles and convolutions of the band are thus embedded in this material.

It will be understood that it is not necessary that the brushes have a cylindrical form as shown in Figs. 9 and 10; but they may be given an oblong, or elongated shape (Fig. 11) by compression in a mold or by other convenient means, or in place of rolling the band, I may fold the some for example as shown in Fig. 12. Small additional bands A may also be placed on the bristles as shown in Fig. 1.3 before the band is rolled up. By this means undulation or corrugation of the bristles is produced when the rolling is finished which prevents said said band, a handle, and a lateral snlar' e ment at one end of the band forming a errule whereby the latter may be attached to the handle substantially as described.

2. A brush comprising a flexible band coiled and compressed to form a stock, brush fiber located between the convplutions of said band, a compressible metallic stern attached to the inner end of said band, a handle, and an enlargement at the other end of said band adapted to form a ferrule for reception of the handle suusta'ii as -2 o describedf 3. A brush compris a flexible band coiled and compressed to orn'l a' stock, bri1sh 1 fiber located between the 'convolutions of said band, a handle, an enlargement at one 25 end ofthe band adapted tofprrn a fe rrulejor. reception of the handle, nails'*i oni e6 ';together the convolutions of theuhand an binding material disposed 'infsaid' ferrule.
