SPECIFICATION forming part of Letters Patent No. 607,105, dated July 12, 1898. Application filed January 21, 1898. Serial No. 667,459. (No model.)

To @ZZ whom it may, concern:

Be it known that we,v\VAL'rER VILKINSON and IRVINE WILKINSON, citizens of the United States, residing at Philadelphia, inthe county y of Philadelphia and State of Pennsylvania, 'l

have invented a certain new and useful Improvement in Reversible Brushes, of which the following is a specification.

Our invention relates to a new and useful improvement in brushes, and has for its object to provide an exceedingly simple and effective means whereby a brush Inay be reversed relative to its handle, thus making it possible to Wear the bristles evenly, thereby increasing the life of the brush. It is a wellknown fact in the useY of brushes of certain classes that the bristles upon the end farthest from the handle are more quickly worn awa-y than those next the handle, thereby destroying the usefulness of the brush much quicker than would otherwise he the case if it were possible to wear these bristles evenly. This we accomplish by making the handle reversible-that is to say, adapting it for application to either end of the brush-back.

With these ends in View this invention consists in the details of construction and combination of elements hereinafter set forth, and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how tomake and usev the same, the construction and operation will now be described in detail, referring to the accompany-v; ing drawings, forming a part of this specification, in which- Figure 1 is a section of a brush made in ac; cordance with our improvement, showing the' handle attached thereto at one end, while the opposite end is provided with similar means for the attachment of the handle; Fig. 2, an enlarged section of a portion of the brushback, also showing a portion of the handle in elevation prior to being inserted within the back; and Fig. 3, a section at the line at of Fig. l. Y l l In carrying out our invention as here embodied A represents the brush-back, in which are set the bristles Bin any well-known or convenient manner, and this back` is here shown as cylindrical in form, as clearly in dicated in Fig. 3, and in each end thereof is formed a socket C, slightly tapering inward for the reception of the shank D of the handle E. Within each of the sockets is formed a'circular groove F, and leading thereto is a longitudinal groove G, the object of which is to permit the key or projection II, carried by the shank, to pass within the socket through the groove G, so that when reaching the groove Fthe handle may be turned upon its axis,

carrying the key into the circular groove, and

described, and when the brushis partially v worn upon the upper end the handle may be disengaged from the back, and when the latter is reversed it may be again attached to the back by inserting the shank within the opposite socket.

When the handle has been attached to one end of. the brush, the socket at the opposite end'is preferably closed by a cap I, which may be provided with prongs J for that purpose, and when the brush is to be reversed this cap must be removed and may be applied to the opposite end of the brush to cover the opposite socket.

f O ne ofthe principal advantages of our improvement is its exceeding simplicity and readiness with which it may be manipulated and a further fact that the cost thereof is but little inadvance of an ordinary brush.

Having thus fully described our invention, what We claim as new and useful is* The herein-described brush, consisting of a back having a tapered socket formed in each end thereof, each of said sockets having an annular groove formed near the inner end thereof, and a longitudinal groove orchannel leading thereto, a handle having a taperedv extension, and a locking-key consisting -of a single piece of wire having the ends thereof bent oppositely at right angles to the body IOO portion, said body portion and one end being fixed our signatures in the presence of two embedded in the extension, the opposite end suhfseribng witnesses.
