useful Improvements in Tooth-Brushes withz Detachable Handles; and I do declare the' following to be a full, clear, and exact description of the invention', such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to toothbrushes and has for its primary object the provision of means for supporting the head of a brush at right angles to the handle, whereby the teeth may be brushed in a vertical direction toward and away from the gums in a line with the grain of the teeth thereby eliminating the possibility of injuring the enamel and causing the teeth to decay.

A further object of this invention is the provision of means whereby the head of the7V brush may be supported in alinement with the handle so that the bristles may be drawn horizontally over the teeth if desired.

the provision of means for detaching the g handle from the brush to greatly reduce` the length of the article whereby it 'may be easily and conveniently carried.

With these and numerousV other objects in view my invention consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings, Figure 1 is a side elevation of my improved device; Fig. 2 is a top plan view of my device showing the brush held at right angles to the handle in dotted lines; Fig. 3 is a central vertical longitudinal section; Fig. 4 is a vertical transversc section taken on the line 4-4 of Fig. 3; Fig. 5 is a vertical transverse section taken on vthe line 5,-5 of Fig.

3; Fig. 6 isan enlarged side elevation showing in detail one end of the brush; Fig. 'l is a horizontal section taken on the line '7 7 of Fig. 6; and Fig. 8 is a bottom view of the end of the handle containing a socket.

In describing my invention I shall refer to the drawings in which similar reference characters designate corresponding parts throughout'.- the several views in which- 1 designates a handle ofthe usual type with one end 2 and having therein a socket 3, the said socket having its vinner end slightly larger` than the 'opening thereto.

ingly shaped bushing 4 having oppositely disposed flanges extending longitudinally with the handle and countersunk in the end `Disposed within the socket is a correspond-V of said handle on eithers'ide of the opening. Y

This bushing is secured in the said aperture or socket 3 byfastening members 5 projecting through an annular flange on said bushing countersunk also in the end of the handle. Depending from thelongitudinally extending anges of the bushing are headed lugs or pins 5, for a purpose tobe hereinafter set forth.

The brush proper as shown at 6, com- 'prises a head or back having `bristles or the like extending from one of its fiat surfaces,

. the opening of the socket in the end of the handle ,for a purpose to be hereinafter set forth. 'llhe rectangular plate disposed in the brush 6 has transversely and longitudinallyV extending grooves l1 projecting radially outward from the said head 9.

In the operation of my improved device when it is desired to use the tooth brush to cleanse the teeth vertically, the detached brush is placed at right angles to the handle 1 and the said. handle is then attached to the brush by forcing the socket therein, into engagement with the head 9 of the brush. Ylhehead 9 of the brush is slightly larger than the opening in the socket of the handle, but is adapted to be compressed while entering the same and then expanding to its normal width within the enlarged end of thesocket, thereby forming a Yfastening to hold the handle and brush together. The depending lugs 5 of the handle which are placed at diametrically-opposite points on either side of the openin the socket are then adapted to engage 't grooves Il that extend transversely across the brush, to

V by disengagin prevent an rotary movement between the handlel an the brush'and hold the same securely in the osition above described,

When it is e'sired tocleanse the teeth by ldrawing 'the brush horizontally thereover, 'the handle is detached from the brush -the head and socket, and then turning t e brush so that it will be in alinement'with the handle. The fastening operation `is repeated as before described with the exceptlon of the lugs of the handle which now engage the two longitudinal grooves of the rush to prevent any rotary movement and xedly secure the parts in position. Thus'it will be seen that the.

improved tooth brush enables a person to brush his teeth either in the ordinary way,s

horizontally across the grain, or in the more correct and sanitary way, vertically alon their grain. Furthermore, this tooth brus having a detachable handle .is veryl convenient, especially for travelers inas- -much as its length may be greatly reduced,

thereby. reducing the inconvenience of transporting .the-same. I' clam:- v 1. A. device of theA` character'- described including a brush, an "upstanding head on .the back of lsaid brush, a handle having a socket to, engage saidhead,` and coactmg grooves and lugs on said brush v,and handle io-hold, the brusiiin adjusted position with relation to thehandle,v

2. A' device of the character described comprising a brush'having a rectangular recess in its back near one end, a correspondingly shaped platev adapted to be secured in said recess, a head having an enlarged slit its upper end upstand'ing from the center of theplate, said plate having transversely and longitudinally extending grooves in its .upper surface, a handle having a socket to engage the head, and pro- ]ecting lugs' from the handle to engage the grooves to hold the brush in adjusted 'position with relation to the handle.

3."A device of the character described compri/sin 'a brush, an upstanding head havinga ase plate with transversely and longitudinally extending grooves on the back of the brush, a handle with a socket HORACE. DQ QAMMACK. Witnesses L. W. Morra'rr, LAvoN BAnNE'rr.
