To all wlwm it may concern:

Be 1t known that we, CHARLES H. CAPEILE and WILLIAM B. FEELY, citizens of the United States of America, residing at South Acton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Brush Bands or Ferrules, of which the following is a specification.

This invention relates to brush bands or ferrules for brushes and particularly for paint and like brushes. The object of the invention is to provide a ferrule which will be light, cheap to make and easy to apply but which will at the same time be fully strong enough to stand all strains brought thereon in use.

A. ferrule for brushesmust not only be strong enough to bind the parts of the brush together but must be strong enough to resist the very great strain brought thereon when the brushes are left in Water and the wooden handles thereof swell under the action of the water. The ferrules heretofore provided have either been so heavy as to render them objectionable to the painter who has to use the brush or else they break when the wooden handle swells as above set forth. Therefore a further advantage arising from the provision of the present invention is that large savings to the dealers in brushes will be effected by the elimination of losses from breakage it being the practice of many dealers to replace brushes in case of breakage of the ferrules, to retain customers.

A further object of the invention is the provision of a ferrule constructed in such manner as to equalize the pressure thereof over the entire width of the same.

A further object of the invention is the provision of a ferrule which may be quickly snapped into position upon the brush and which Will be self retaining during the time that it is subjected to further manipulation such as soldering or the like. It is also an object of the invention to provide a ferrule of the character above set forth in which the joint uniting the ends of the same is of such a nature and in such location as to adapt the ferrule to be quickly and easily soldered by machinery.

Further objects and advanta es of the invention will be set forth in the detailed description which now follows.

In the accompanying drawing:

having the ferrule applied thereto.

Fig. 2 is an edge elevation of said brush.

Fig. 3 is a horizontal sectional view upon an enlarged scale through the joint of the ferrule and Fig. 4 is a greatly enlarged view of a part of the joint of the ferrule illustrating the interengaging tongue.

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring to the drawing 5 designates the body of the ferrule or brush band which is preferably provided with strengthening rims 6 to add rigidity to the structure.

The invention resides more particularly in the joint by which the ends of the band are secured together. As is best illustrated in Fig. 3 the ends of the band are overlapped at one edge of the brush and these overlapping ends are provided with vertical rows of hook like tongues 7, the material of the band being cut out as at 8 to permit these tongues to be struck therefrom.

In applying the ferrule the tongues 7 are hooked into engagement with each other it being apparent that the tongues of one end of the ferrule will project through the corresponding openings 8 of the opposite part of the ferrule. Since the row of tongues extend throughout the entire width of the ferrule it-follows that the pressure exerted by the ferrule will be equal throughout the entire Width thereof when these tongues are hooked into engagement with each other. The tongues are then flattened into tight engagement with each other and the joint is soldered. Since the ferrule is self retaining it is possible to perform the soldering by machinery and the formation of the tongues and the openings 8 is such as to render the soldered joint a very strong one because the walls 8 of the openings 8 lie outwardly of the tongue 7 which projects therethrough and the outer surface of this tongue is united to these walls by the solder. Furthermore the edges 7 of the tongue 7 are not only united to the part of the Wall 8 adjacent thereto but they are also united to the outer surface 7 of the exposed portions of the tongues 7 which lie immediately therebeneath.

It will thus be seen that a very strong joint is provided which renders it possible to employ a structure of comparatively light Weight for brush bands of this charaoter.- A very slight dilference in Weight is of importance because very often the painter is doing overhead Work and the strain upon the Wrist and arm is very great at the best.

It is to be understood that the invention is not limited to the precise construction set forth but that it includes Within its purview Whatever Changes fairly come Within the spirit of the appended claim.

Having described our invention What we claim is; a

A ferrule having overlapping ends provided With transverse rows of oppositely, directed, tapering teeth formed by striking out saidteeth from the material of the ferrule to thereby provide openings, the teeth .upon one end of the ferrule projecting through the openings of the other end of the ferrule and vice versa', the tapering of the teeth limiting the degree of their entry into the openings to provide solder receiving recesses.

In testimony whereofi We aflix our signatures;
