all whom it may concern.'
Be it known that I, JAMES L. PITCHER, re-
siding at Brooklyn, in the county' of Kings i and Statey of New' York, have invented cer- 5 tain Improvements in Brushes, of which the V of a rotating spindle.
ill)
rllhe object of the invention is to provide an improved construction for holding the brush material in position in a very secure and permanent manner. y
The principal feature of the invention resides in a cylindrical brush head having a groove around its circumference and longitudinal holes for the brush material extending into this groove from both ends.
Double-faced brushes employing this construction are particularly adapted'for clean ing the contact surfaces of heat coils on telephone central office protectors, the brush material in this case comprising strands of suitable iron or steel Wire.
A more comprehensive idea of the inven tion will be obtained from the following description and the annexed drawings, Figure .l of which represents an assembled brush 0 embodying the features of the invention,
Figs. 2 and 3 are'vews of the brush head of the invention showing the position of the binding holes, Fig. 4 shows the brush attached to the end of a flexible shaft driven by a motor or other source of power, Fig. 5 is a. modification of the brush of Fig. l in which the binding holes in one end. of the brush pole are staggered, that is, out of alignment, with respect to the holes in the otherk end, Figs. 6 and 7 are views of the brush head of Fig. 5 showing the staggered position of the, binding holes and Fig. 8 is a longitudinal cross-section of the brush of Fig. 5 Which shows the method of binding the brush strands in the groove.
Referring to the drawings: l is a spindle adapted to be attached to suitable driving means such as the flexible shaft 2 (Fig. 4). The brush head 3 is rigidly attached to one end of the spindle l and is provided With a groove 4 extending around its circumference. Holes 5, Fig. 3, are drilled in one end of the brush head 8 substantially parallel to the spindle l and extend into the groove 4, and similar holes are drilled in the other end of the brush head Which also extend into the groove 4. A plurality of strands 7 of a suitable brush material such as iron or steel Wire :are doubled 'back on themselves and drawn in through the holes 5` into the groove 4, 'Where they are bound in position by binding Wires 8 and 9, Which are vthreaded `through the groups of strands in rotation around the circumference of the groove as shown, `the ends-of the binding Wires being then joined together by twisting, and soldering or in any other suitable manner. brush strands can, after binding, be trimmed down to any desired length. The foregoing if described construction can, of course,be used in any brush structure Where aV double-faced rotary brush is required, and the brush strands can be of any suitable material. A. modification of the foregoing construction, as regards the holes for the brush material, is shown by Figs. 5, 6, 7 and 8. In this modified construction, holes 10, Figs. 6 and 7, are drilled in one end of the brush head 3 substantially parallel to the spindle 1 and extend into the groove 4. Similar holes l1 are drilled in the other end of the brush head Which also extend into groove 4. In this case, however, the holes in one end of the brush head are staggered, that is, out of alignment, With respect to the holes in the other end, as shown in Fig. 6, thus perinitting the looped portions of the brush material in one end of the brush head to exe tendpast those in the other end so that a single binding Wire can be threaded through each loop in turn around the circumference of the groove.
That is claimed is:
1. In a rotary brush, a. cylindrical brush head having a groove around its circumference at right angles to the axis thereof,
longitudinal openings in each end of said brush head extending into said groove and parallel to `the axis of said brush head, brush material in said openings extending into said groove, and means for binding said brush strands together in said groove. 2. In combination, a source of power, a flexible shaft driven thereby, and a doublefaced brush attached to one end of said shaft,
said brush comprising a cylindrical brushV head having a groove around its circumference, longitudinal openings extending into said groove from the opposite ends of said If necessary, theV brush head, and brush material in said openingsextending .into said groove.
3. In a rotary brush, a Cylindrical brush head having a groove around its eireuniterence at right angles to the axisV thereorn and longitudinal openings extending into said groove from eaoh end, said openinge containing brush 'material extending outwardly troni each end ot said head.
4. In a. rotary brush, a. Cylindrical brush head arranged with a groove around the circumference oit Said brush head, and hav-v ing longitudinal openings extending into said groove from each end oi said brush head, and brush material in said openings joined together .in said groove by binding ineans.
5. In arotary brush, a cylindrical brush head provided with a groove around-the oiroiunterenee otsaid brush head at vright angles to Vthe axis thereof and withzlongitudinal openings parallel to eaeh other extending intoeaid groove from each end,
brush material in said openings, and hinding means for the brush material.
6. In arota-ry brush, a Cylindrical brush head having a groove around its circumference and longitudinal openings-extending therein from e'a'eh lend of said brush head, brush inaterial in Said openings', and extending outwardly froin eaoh end ot Said head and means for binding said brush 1naterial in said groove.
7. In a rotary bnush, a cylindrical brush head having a. groove around its circumference at right angles to the axis of Said head and having vopenings 'extending into said groovek from each end ot Said head, looped Strands of brush rnaterial extending into said groove through said openings, and a binding Wire threaded through said looped brush material.
In testimony whereof, I have signed my naine to this Specification thisk 9th day ot August, 1923.
