BAKER BRUSH COMPANY,- OF NEW' YORK,
NEW YORK, ASSIGNORS TO N. Y., A CORPORATION OF NEW YORK.
Application filed August 6, 1921. Serial No. 490,381.
To all whom it may concern:
Be it known that we, FRANK Jonuonn, residing at Brooklyn, county of Kings, and State of New York, and HARRY SHULMAN,
residing at Brooklyn, county of Kings, and State of New York, both citizens of the United States, have invented certain new and useful Improvements in Paintbrushes,
fully described and represented in the fol.
lowing specification and'the accompanying drawings, forming a part of the same.
The present invention relates to a flat paint brush having a tuft of bristles glued within a ferrule, and nails extended through the ferrule and the bristles,and their ends clenched to clamp the ferrule firmly upon the bristles.
Heretofore, in such constructions; the nail-holes afiorded access for paint and various solutions in which the paint brush is used, which operates to soften the glue and weaken its hold upon the bristles.
The pressing of the nail-heads tightly upon the tin of the ferrule produces slight depressions or sockets in which paint accumulates around the nail-heads, rendering it very difficult to entirely remove such paint when the brush is to be used with another color, which would be streaked or spotted in a greater or less degree by the color loosened from the recesses when immersed in fresh paint.
To prevent these results from the presence of the nail-heads and clenched ends, it has been common heretofore to tin the nail-heads by the aid of acid solutions and to flood the recesses and the nail-heads with solder.
Such operation is very tedious and consumes a great deal of solder, and is wholly 40 avoided in the present invention, in which a strip of metal considerably wider than the nail-head is wrapped around the ferrule over the nail-heads, and the edges and ends of the strip soldered to the smooth metal of the ferrule.
Such a cover-strip avoids the necessity of tinning the heads of the nails, with the use of acid which is very corrosive to the metal, and it saves a large proportion of the entire time heretofore required, as the tinning of the nail-heads is not only avoided, but the soldering of the strip to the smooth surface of the ferrule takes only a very small proportion of the time and solder that is required when the nails are tinned and V the layer of solder is made heavy enough to properly cover the nail-holes.
The construction will be understood by i 'eference to the annexed drawing, in which is ig. l is a perspective view of a brush with the cover-strip partly secured thereon; Fig. 2 s a side elevation of the brush entirely finished; Fig. 3 is a vertical section on line 3-3 in Fig. 2; Fig. 3 shows the relation of the cover-strip to the nails upon a larger scale than Fig. 3; Fig. i is a section on line 4'4 in Fig. 8 of the structure shown in Fig. 1; Fig. 5 is an end View of the cover-strip; and Fig. 6 is a view of the same before its application to'the brush.
The brush is shown with the usual ferrule a embracing the upper end of the bristles I) and formed with a metallic cap 0 to which the tubular metal handle (Z is attached.
In Figs. 2 and 3, the heads 6 of nails 7 are visible upon the side of the ferrule with a little recess 6 around each head caused by driving and clenching the nails in their working position.
In the common process, such recesses would be filled with solder, and the heads of the nails would require to be tinned to make the solder adhere to them; but in the present construction the nail-heads and points are wholly covered by a strip 9 having, as shown in Fig. 5, the edges sloped inwardlv to fit close against the ferrule. I
To make an approximate flush joint of this strip with the body of the ferrule, shallow grooves h are formed in the ferrule along the sides of the nails, and the edges g of the strip fitted into these recesses and are soldered therein, as shown in Fig.
The fitting of the parts together is shown in the enlarged view of Fig 3, which exhibits the edges of the strip fitted into the shallow grooves at the sides of the nailheads.
In Figs. 1 and 4, the strip is shown partly soldered to the ferrule, the nail-heads being exposed upon a portion of the ferrule, and
the strip 9 turned backwardly to expose them to view.
hen soldered, the edges of this strip would be pressed closely into the shallow grooves h and soldered therein, and the ends of the strip overlapped upon one another and also soldered.
The width of the strip is proportioned t bring its sloped edges into the grooves, and
as the surfaces are smooth and flat they are readily soldered, and the soldered joint is much more perfect and permanent than where the solder is applied to the nails.
The strip presents a much better appear ance than a row of nail-heads, and not only conceals the nails from view, but prevents injury to the painters fingers in cleaning the brush if the nail-heads be broken, split, or present any sharp edge.
It is common in such paint brushes to pierce a hole '5 in the cap inside the handle d, to hasten the drying of the glue within the ferrule; but if a hole 9' be made in the tin handle to hang up the brush, as shown in Figs. 1 and 2, it permits paint and solution to gain access to the inner ends of the,
bristles and constantly soften the glue at that point.
To avoid this, we insert a cork or plug is in the tin handle, which is commonly made tapering, so that the cork when forced into the handle fits tightly and may be pressed down close to the ventilating hole 71, as shown in Fig. 3, thus excluding solutions from the hole z.
Our invention not only gives the brush a better appearance, but protects it from the access of paint and solution to the interior of the cap, and thus renders much more durable the hold of the glue upon the bristles.
Having thus set forth the nature of the invention what is claimed herein is:
1. In a paint brush, the combination, with a ferrule and the bristle-tufts enclosed therein and nails driven through the ferrule and bristles, of a metallic strip embracing the ferrule over the ends of the nails and soldered to the ferrule to exclude paint and solutions from the nailholes.
2. .In a paint brush, the combination, with a ferrule and the bristle-tufts glued therein and nails driven through the ferrule and bristles, of a metallic strip embracing the ferrule and having edges sloped inwardly and soldered to the ferrule, as and for the purpose set forth.
3. In a paint brush, the combination, with a ferrule and the bristle-tufts enclosed therein and nails driven through the ferrule and bristles, the ferrule having shallow grooves along the sides of the nail-ends, of a metallic strip having the edges sloped inwardly and soldered in the said grooves, as and for the purpose set forth.' 1 v In testimony whereof we have hereunto set our hands.
