.ments in tooth brushes, and it is an object PAUL B. BURLEIIIGH, OFSOMAHA, NEBRASKA.

TooTHBRUsH.

Specification of Letterslatent. Patented Jan. 13, 1920.

Application led October 26, 1918. Serial No. 259,820.

To all whom t may concern Be it known that I, PAUL B. BURLEIGH,

'a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Toothbrushes, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improveof the invention to provide a novel and iniproved device of this general character wherein the brush head is flexible, so that the cleansing operation may be materially facilitated.

A further object of the invention is the provision of improvedmeans, for connecting the handle, and the brush end of the tooth brush. In carrying out this object it is the aim to provide a. tubular thimble` having means between the ends of the thimble, for separating the handle from the body of the brush head.

A further object of the invention is toI provide stitfening means, consisting of a metal member or rod, preferably steel embedded in the brush head. One end of this member or rod is cylindrical, and extends to the rear end of the brush head, and in close position to the separating means between the brush head and the handle, and also within the thimble. This construction insures the strength and rigidity. at the point where the brush head and the thimble are telescopieally united. At a point a short distance beyond the thimble the metallic rod or member gradually tapers` which allows the greater end porton of the rubber brush head to resiliently yield, and vet at the same time insure sufiicient rigidity, to cause the bristles of the brush to bear firmly upon the teeth while the brush is in use. The resiliency of the greater end portion of theI brush head, allows the greater portion to bc curved or disposed, in order to separate the bristles of the brush, to facilitate cleaning.

The invention consists in the details of construction and in the combination and ar-l rangement of the several parts of my improved tooth brush whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter ,more fully set forth.

The novel features of my invention will i hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to dece l scribe the same with reference to the accom-J panying drawings, wherein:

Figure 1 is aview in side elevation of a tooth brush constructed in accordance with an embodiment. of my invent-ion. the second position of the head or back being indicated by dotted lines; and A Fig. 2 is an enlarged fragmentary view partly in elevation and partly in'section of my improved brush as herein embodied.

As disclosed in the accompanying drawings. 1 denotcsa brush head .or back formed of rubber or other similar tiexible or resilient material. and which has set or otherwise attached thereto the bristles 2.

3 denotes a thimble or ferrule provided at its opposite ends with the sockets 4 and. 5. An end portion of the head or back 1 is itted wit-hin the forward socket 3, while the second or opposite. socket l is adapted to receive an end portion of the handle 6.

Extending longitudinally of the head or back 1 and embedded therein is an elongated resilient reinforcing rod 7 preferably formed of steel, and which is tapered toward its outer end whereby the head or back 1 is given suflicient strength, and which serves to constantly urge the head or back l 1n one direction or ina direction toward the work when the brush is in use.

From the foregoing description, it is thought to be obvious that a toothbrush constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it` may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modifica# correspondingly `with the portion that extends at an obtuse angle, thereby affording resiliency for said portion, whereby said portion may yield when urging the bristles toward their work, a handle for the head, and means for uniting the head and the handle, said means being so positioned with relation to the rear portionof the embedded means, as to insure strength and rigidity at the point of connection of the uniting means and the head.

2. The combination with a pliable tooth brush head, provided with brush bristles and having a portion extending at an obtuse angle to the rear portion of the head, of re silient means embedded in the head and corresponding in shape thereto and tapering correspondingly with the portion that extends at an obtuse angle,\tlereby a'ording resiliency for said portion, whereby said portion may yield, when urging the bristles totgard their work, a handle for the head,

an' a thimble into the opposite end of which the handle and the head are respectively telescopically inserted, thereby. uniting the =ble -being so positioned with relation to the embedded means, as-to insure strength and rigidity at the point of connection of th head with the thimble.'

3. The combination with a pliable tooth brush head, provided with a tapering part signature in the presence of two witnesses.
