Application filed March 2.1907. Serial No. 360.236;

T 0 all whom it may concern:

Be it known that I, CHARLES A. FETTERs, a citizen of the United States, of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Sectional Hair-Brushes, fully described and represented in the following so that when the strips are separated from one another each row of bristle-tufts may be readily cleansed by washing and scrubbing, because accessibleu on both sides.

The strips are made 0 uniform cross section and provided with corresponding tongues and grooves u on their opposite ed es, so that they may fie all manufactured .in ong bars by a uniform process and then cut into portions or strips of aduated length to form a brush-block 0 oval or rounded contour. Such mode of manufacture permits brushes of various sizes, forms and contour to be made all from the same kind of strips, and it permits, when desired, the tufting of the long strips before cuttin up into sections of graduated length, an

' thus greatly cheapens the manufacture of 'the brush as the tufts can be inserted by automatic machinery with vmuch greater rapidity and correspondingly less expense than if insertedin the brush-block.

In addition to the tongues and grooves which form the tufted strips in alinement when assembled, means isrequired in the finished brush for holding the strips from longitudinal movement or displacement, and also means for clamping the strips detachably together. Such means operates preferably upon the opposite outer strips of the block so as to clamp the other strips between the same. When a handle is required upon the brush, it may be formed integral with the middle section or strip, and-the addition of a handle does not therefore increase the number of ieces in the brush.

The handle is generally of greater width than a sin le tufted strip, and its width may be exten ed by gluing portions of the tongued and grooved strips upon its opposite sides to the desired width and then trimming the same to the desired shape. The center stri of the brush and the handle would be ormed of strips before any tuftholes were drilled in the strips, thus making the handle free from any such holes. In the construction illustrated, I have shown a straight rod" or bolt extended through the sections to prevent longitudinal displacement, and a spring-clip for clamping the sections together.

In my Patent No. 805,431 dated November 21, 1905, which is a division of the said application No. 230,648, I have shown a ho t extended through the sections with a ASSIGNOR TO SANITARY SECTIONAL BRUSH i A CORPORATION OF NEW YORK.

head upon one end and a nut upon the other,

toperform the double function of holding the strips from displacement when clamping them together, but the bolt illustrated herein has no head and nut to 0 erate as a clamp.

In the drawing, igure 1 shows an oval brush-block for a so-called army and navy brush with a portion of the strips separated to show their detachable nature, a bolt extended through the strips and a sipring-clip indicated in dotted lines. Fig. 2 i ustrates a brush with ahandle having the spring-cli placed on the back of the brush and the c ip-jaws embracing the outer strips. Fig. 3 represents the end of the brush-block in Fig. 1 or Fig. 2, with the spring-clip thereon. Fig. 4 is' a perspective view of the s ring-cli and Fig. 5 is a cross section of t e hand e and its greatest width upon the brushinFig. 2, I

a designates the se arable strips each containing one row of oles b for the bristletufts b, and each provided upon its oppogroove slipped ofi as indicated at the rig t side of Fig. 1, when it is desired to wash and cleanse the bristles.

As each strip has only one row of the bristle-tufts, the tufts are accessible upon both sides and can be washed and cleansed with great ease and completeness.

The spring clip, adapted to clamp the outer edges of the brush-block, is shown in Fig. 4 consisting of a flat plate 9' having jaws h at the opposite ends, the plate being adapted as shown in Fig. 2 to lie across the back of the brush-block and the jaws to embrace the edges of the opposite outer sections as shown in Fig. 3, and to be held thereon by the elastic clamping pressure of the jaws. The clip is indicated in dotted lines in Fig. 1 to show itsrelation to the sections or strips of that brush-block when assembled.

The bolt 6 is shown in dotted lines in Fig. 2, and as also in Fig. 1, except where exposed between arts of the separated strips. The brush-block is shown in Fig. 2 with a handle extended from the middle strip, the handle being shown formed as indicated in Fig. 5 by gluing similar tongued and grooved strips at the sides of such middle strip to securethe desired width, the edges of such supplemental strips being cut out and the edges rounded as indicated in Fig. 5 to form the handle.

It will be readily seen that the strips a can be formed by suitable machinery of any desired length andthen cut up into pieces, to form the side portions of graduated length which are required for a brush of oval or rounded contour, and such long strips may,

. if desired, be tufted before they are cut into the desired sections. By this process of manufacture, the strips may be cut to form a brush-block of any desired length or width, and the same machinery and processes may thus be used for pre aring the material to make all kinds of brus es.

In a brush having a handle, it is immaterial so far as the brush-block is concerned, whether the handlebe formed of a plurality of tongued and grooved strips as shown in Flg. 2, or be made of a single wide piece integral 1with the strip for the middle of the brush In the practical use of f the brush, the clamping means is disengaged when it is desired to cleanse the bristles and the tufted strips are then readily se arated and thrown into a bowl of water wit fsuitable disinfecting material. l

As each strip possesses only a single row of bristle-tufts they may be scrubbed and cleansed far more thoroughly than where two or more rows are contiguous, and when suitably cleansed and dried the strips are readily re-assembled and the clamping means re-applied to hold them in their working relation.

It is" obviously immaterial whether separate means as the boltf and clamp g be used for holding the strips from longitudinal displacement and clamping them together, as shown in the Fig. 2 of the drawing, or a single agency be used to perform both functions, as with the bolt and nut shown in my Patent No. 805,431.

Having thus set forth the nature of the invention what is claimed herein is:

l. A brush block wholly divided into straight longitudinal strips, each strip being provided with. a row of bristle-tufts and the strips all having parallel edges with tongue and groove connections upon the adjacent edges for holding the strips in alinement, means for holding the strips from longitudinal movement when assembled, and means for clamping the strips detachably together for conjoint use, the sides and ends of the strips upon the edges of the block being trimmed to the contour desired.

2. A brush having the entire brush-block divided into straight longitudinal strips, each strip being provided wlth a row of bristle-tufts and the strips all having parallel edges and formed with a groove upon one edge and an integral corres onding rib upon the opposite edge for hol ing the strips in alinement, a. rod extended through the strips to prevent longitudinal movement, and means operating upon the opposite outer strips of the block for clamping the strips together.

3. A brush having the entire brush-block divided into straight longitudinal strips, each strip being provided with a row of bristle-tufts and the strips all having parallel edges with a groove upon one edge and an integral corresponding rib upon the opposite edge for holding the strips in alinement, means for holding the strips from longitudinal movement when assembled, means operating upon the opposite outer strips of the block for clamping the strips together, and a handle connected with the middle strip at one end of the block.

4. A brush having the entire brush-block divided into straight lon itudinal strips, each strip being provided with a row of bristle-tufts and the strips all having parallel edges with a groove upon one edge and an integral corresponding rib upon the opposite edge for holding the strips in alinement, means for holding the strips from longitudinal movement when assembled, means operating upon the opposite outer strips of the block for clamping the strips together, and a handle connected with the middle strip at one end of the block and having tongued andgrooved strips like the strips of the block, glued together and rounded to form said handle.
