- J UNITED sT Tes PATENT orr ca HENRY 11mm, OCEAN TOWNSHIP, IONfiOUTH COUNTY, NEW JERSEY Application filed Iebruary 19, 1931. Serial No. 516,964.

A further object of my invention is the provision of a tooth brush in which the bristles of the brush are removably secured in a flexible holder which in turn fits the handle, the bristles being set at such an angle to the handle as to facilitate vertical movement of the brush in the action of cleaning the teeth, as distinguished from the horizontal move ment employed with the usual brush.

A still further object of my invention is the provision of a structure having the characteristics above noted and additionally provides brushes and a holder therefor whereby a brush aftena single use is thrown away and may. be readily substituted with another.

To improve the attachment of the brush to the handle and to reduce the cost of manufacture and hence price to the consumer'my improved structure provides a strip of flexible material to which the bristles of the brush are secured. Preferably this'. support for-the bristles is capable of accommodating a plurality of brushes so that previous to insertion in the holder a brush and its support may be torn from the others and after use may be thrown away. This, it will be appreciated, provides at very sanitary structure and if the brushes are furnished in strip form, that is, several brushes secured to the one strip, loss of the brushes is of course reduced to a minimum.

In the drawings accompanying this application:

Fig. 1 is a drawing illustrating an embodiment of my invention;

Fig. 2 is a side elevation of the device of Fig. 1;

Fig. 3 is a with the brush removed; and

Fig. 4 is a view of the brush structure and support therefor.

Referring to the drawings in detail, my inyention, as illustrated, takes the form of a handle designated 1 provided with a reduced threaded portion '2 at its upper end.

Cooperating with this handle is a flexible front view of the device of Fig. 1 I

clamping head composed of upper and lower sections designated 3 and 4, respectively. This clamping head is for the urpose of clamping the brush in place as Wlll be presently explained.v The upper section 3 of the clamping head is provided with a threaded hole 5, while the lower section is provided with a hole 6; the threaded reduced end 2 of the handle is screwed 'into these holes. As will be seen from Fig. 3, for instance, the no upper section of the clamping head may be provided with holes 7 and the lower section with pins 8 to prevent relative rotation of the two sections of the clamping, head.

The bristles 9 of my improved brush are as carried in a flexible support 10. This support conveniently comprises two strips of suitable flexible material such as paper or cloth, designated 11 and 12, or one piece of material simply folded over. The inner face of either or both of these strips of material is provided with a suitable adhesive shown at 13 and which may be a rubber cement, for instance. The bristles 9 are interposed be- I twieen the strips 11 and 12 and when pressure 15 is applied to the support 10 it will be obvious that the bristles will be held in place. If desired the cement may be vulcanized.

This arrangement or construction provides a flexible carrier or support for a plurality of so sets of bristles 9, a brush, for instance, comprising three sets of the bristles as illustrated, although of course the number may be varied as desired depending a good deal upon the width of the end'of the holder for the brush. so

In use the required number of bristles 9, for instancethe three sets ofthe bristles as .illustrated in Fig. 4, may be torn from the support 10 along the line 14 for instance of Fig. 4 and the severed support with the to bristles attached thereto placed in the holder substantially as shown 'in Fig. 2, the upper and lower sections of the holder then being clamped upon the bristle support and when the handle 1 is screwed up the threaded re- 1' duced end passing through the perforation 20 in the support it will be obvious that the brush will be securely held in position.

This provides a very inexpensive construe tion and permits of strips of spare brushes or head transversely of the ban refills to be sold at a cost to the consumer which will enable the consumerto discard a set of bristles after a single use, thereby providing an extremely samtary brush 'articularly as compared to the usual toot brush which is one-piece and may be, and probably usually is, used until worn out.

It will be seen also that the bristles 9 are so arranged as to rovide a fairly thin flat brush structure and t at by disposing the clampling le 1, as i ustrated, the brushes are held in position with res facilitate vertical movement of the cleaning the teeth which is the accepted modern practice.

It is to be understood that while I have shown the handle 1 as provided with a threaded stud 2 to engage the threaded hole 5 in the upper member 3 of the clamping head of this device that the upper member 3 may be provided with a threaded stud and the upper end of the handle 1 with a threaded hole to receive the stud.

What I claim is 1. An article of the class described comprising in combination a handle, a detachable brush-clamping head carried at the end of the handle, and a brush head comprising bristles with a flexible mount therefor removably clamped in said head and extending nearly at a right angle .to the handle.

2. An article of the class described comprisin in combination a handle, a brushclampmg head at the end of the handle, and a flat brush head comprising bristles mounted on a flexible support removably clamped in said head, the plane of the brush head being at an angle transverse of the longitudinal axis of the handle. 3. An article of the class described comprising in combination an elongated handle, a two-part clamping head aflixed to the outer end of the handle, and a flat brush head comprising bristles detachably clamped between the two parts of the clamping head, the plane of the brush being at an angle transverse of the longitudinal axis of the handle.

4. An article of the class described comprising in combination an elongated handle, and a brush head comprising bristles mounted on a flexible support removably carried by the handle, the brush head extending nearly at right angles to the handle.

This specification signed this 17th day of February, 1931.
