SPECIFICATION forming paraaffirm/ters,` Patent No. 702,530, dated .rune 137,190.2.
Application iiled I-Tovember-Zl', Y11'901. Serial No. 83214-7. (llofinodel.)l u
To all whomfitmay concern: l V
Be it knowntthat I,JoHN F. BOWDITCH, a citizen of the United States, 'and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new.
and usefulllmprovements inBrushes,of which the followingis a specification.
This invention relates to an `improved method of securing the bristles of'a brush to the handle.
As brushes are sometimes manufactured the bristles are compressed, bound, and cemented together onto a Wooden core or body. It is well known that the bristles of a brushv necessary to compress the bristles at the sides with considerable force. This pressure tends to spread out and weaken the ends, so that the bristles are not firmly held at these points.
. Another objection to the above method is that the binding of the bristles causes them to be pressed together near their butts, so that they if they were spreadout at this point. i. 1
The object of my inventioni-is to overcome the above-named defeets,and therebyproduce a brush in which the bristles,areso'firmlysea cured to the handle that they' will 4not be will not hold as much paint 'or other lquidascaused todrop out from the shrinking -or'swell-VV ing of the wood or'frorn any 'other'cauges' f which I am aware. f J 1 A further object of my inventionis'to pro-v duce a brush which is provided with means for spreading the bristles inside the body near the butts and for forming the brush so that it will beas solid at the ends as inthe midi? dle. Iaccomplish this object by binding the butts of the bristles in sections by meansof metal ferrules, which are compressed about the bristles in a mold and then held together by nails, and by securing these sections to the end of the handlefby means of ametal plate having a series of`teeth which pass over the edges ofthe feriules and into the bristles.
For a complete understanding of my invention reference is made to the accompanying drawings, in which- Figure l is a side elevation of a flat brush section removed. Fig. B isan end elevation thereof. -FigA is'asection, ontheline Z Z of Fig; l, one of the brush-sections being partly broken away. Fig. 5 is a side view of one of the'brush-sections. Fig; 6`is"a cross-section on line- VV W of Fig. 5. Fig. 7 is a cross-section on line Y. Y of Fig. 1. l
rIhe handle l isV provided with a ilat tongue 2 at its head 10, which corresponds in shape to the desired shape of the brush. Said tongue is smaller than the main part of the head, so that a flat surface 3 is formed about it which is perpendicularfto the sides of the tongue. A metal plate 4, preferably of brass, is firmly secured to the outer end of tongue 2, and the ends of said plate are bent down against the ,side ends of tongue 2, as shown in Fig. 2, thus preventing the tongue from being split when nails aredriven therethrough. The side edges of said plate are provided with a regular series of transverselyfprojecting teeth 5, said teeth projecting beyond the side edges of the tongue, as shown in Figs. 4 and '7.
The manner of securing the bristles to the construction just described is as follows: A
'mass of bristles B, which are just sufcient for. half the brush, are drawn into a ferrule 6, of.-.pliable metal, preferably a composition zinc. The butts are made even and dipped into Cement to a depth about 'equal to the lwidth of the ferrule. `A series of small nails 7 are then driven coin pletely through the ferrule and butts of the mass and clenched on the opposite side, as indicated in Fig.' 6, and then the ferrule is compressed between suitablyshaped molds, thus'clenching the nails tight against the outer sidesofthe ferrule and so firmly binding the ferrule about the bristles that they would be'irm'lylield even if the cement werenotemployed. However,thecement materially strengthens the 'connection and is therefore preferably used. ,When the section is molded, the ends Gthereof are bent transversely to the same side, as shownvinFig. 6.
A second section B' is made inlike manner,
and the two sections are then placed with their butt-ends against the surface 3 of the head, the inner sides thereof being pressed against the sides of the tongue 2 and the transversely-bent ends 6 of each section meet- IOO ing about the ends of the tongue 2, as shown in Fig. 4, so that the ends of the brush are continuous, as shown in Fig. 3. The width of ferrules G are such that when the sections are placed in this position the teeth 5 will just pass above the inner edges thereof into the mass of bristles, nearly to the outer sur face thereof. A series of large nails S are then driven completely through the ferrules G, the butts of both sections, and the tongue 2 and clenched, as shown in Fig. 7, thus firmly securing each brush-section to the handle. To give the brush a finished appearance I bind the butt-ends of the sections and the head of the handle with a metal band 9, which is nailed to the head. I also secure metal ears Il inside of the band 9 at each end of the brush, said ears extending beyond the outer edge of said band about three-fourths of an inch. These ears ll perform a very important function, in that they may be bent inwardly into various positions, so that the width of the iiag of the brush may be so varied that the brush may be lnade tapering or square. These ears also prevent small bunches or sections of the bristles from bending away from the main part of the brush. The bristles at the ends of the brush are bound with the same tension as those in the middle, and as the bristles are also uniformly distributed from end to end the brush will apply the paint evenly through its entire width. This enables a painter to draw solid straight-edged lines with the brush and to paint close to a wall without touching it, as the brush will apply the paint as freely at the ends as in the middle, and there will be no loosely -projecting bristles to make ragged lines beyond the main part of the brush.
In addition to the functions of the teeth 5 of plate e in holding the brush-sections against the end of the handle they also perform the very important function of spreading the bristles near the head, as indicated in Fig. 2, practically forming chambers which will hold the paint or other liquid where the bristles are usually pressed closely together. As the teeth do not protrude through the outer surfaces of the bristles, there will be no appreciable leakage of the liquid to the surface from the chambers formed thereby. Moreover, it has been ascertained from practical usc that the transversely-extending teeth in addition to giving fullness to the body of the brush also increase its elasticity and prevent to a large degree the tendency which the bristles have to become matted together, and thusprevent the free flow of the liquid from all points as the brush is drawn over a surface.
From the foregoing description it will be apparent that I have produced a brush in which the shrinkage or swelling of the Wood cannot possibly affect the security with which the bristles are attached to the head. Moreover, I have accomplished this result without increasing its Weight.
Although my invention is not confined to the precise construction illustrated and certain features of my invention may be ad vantageously used in other forms of brushes, yet I consider the particular construction and application which I have disclosed to be the most advantageous of any of which I am at present aware.
Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is as follows:
l. A brush having the holder provided with a projecting tongue, two brush-sections which are secured to opposite sides of said tongue, each of said sections comprising a metal ferrule, a mass of bristles which are arranged therein, and a series of nails which are driven through one side of each ferrule and clenched on the opposite side thereof to clamp the respective sides of the bristles upon the bristles which they inclose.
2.
