IMPROVED WHISK-BRUSH.

Specification forming part of Letters PatentrNo. 36,560, dated September 30, 1862.

-make a part of this specification, and in which- Figure l is a side elevation of one of my -improved whisk-brushes, and Fig. 2 is a lon` gitudinal section of the same. Fig. 3 represents a whisk or head of broom-corn, and Fig. 4 three of the peduncles or long slender seedstalks or brush-fibers of the whisk.

The same letters refer to like parts in all the figures.

The central portion, A, of my improved whisk-brush is composed of v layers of the peduncles or brush fibers b of broom-corn whisks, Fig. 3, bound upon a core, c, of wood, by means of twine or wire d d d al, substantially the same as the central portion of Whiskbrushes heretofore made of the brush fibers only of broom-corn whisks are commonly formed. The covering E of the whisk portion of my improved brush is also composed of layers of the brush fibers b only of broom-corn whisks, and is laced -to the central part, A, of the brush by wire or twine ff, and is bound directly to the wooden core O at the place g just above the shoulders h h of the brush, all substantially as in common whisk-brushes made of the brush fibers only of broom-corn whisks bound upon a wooden core; but my' improved whisk-brushmay be distinguished from all others by the fact that in my improved brush the very same peduncles or brush fibers b, which constitute the covering E of the central portion, A, of the brush, also extend from the shoulders h h of the brush outward, so as to form the wholehandle I, which theoperator grasps in whisking the brush, the said brush fibers being bound by wire j upon an equal extension of the core O upon which the central parte, A, of the brush is made, all substantially as is shown by Figs.- 1 and 2 of the annexed drawings.

My improved whisk-brush above described, and shown by Figs. 1 and 2 of the annexed drawings, with the covering m of its handle I formed of the very same brush libers of broom-corn which constitute the covering Eef 'the brush, is substantially different from, and

has superior utility to, the whisk-brushes in common use,which have the wooden core C, and itself serves directlyas the handle which the operator grasps in using the' brush, the same as would be the case with the brush shown in Fig. 2 of the annexed drawings if the covering E of the brush did not extend along that part of the core O which is between the linea z and the end x of the handle, for when the wooden core itself is the handle of the brush the ordinary operation of whisking the brush about back and forth in using the brush necessarily tends to loosen and separate the whole brous part of the brush from the core C; but when the handle of the brush consists of the fibrous covering E bound upon the core C, as shown by Figs. vl and 2 of the annexed drawings, the core O remains passive within the brush, while 4the latter is whisked about in use, and the voperation of using the brush does not tend to loosen and separate the fibrous part of the brush from the core. Consequently my improved whisk-brush is far more durable than Vsuch whisk-brushes as have ythe core C itself serve as the handle of the brush.

My improved whisk-brush, constructed of the brush fibers b only of broom-corn whisks,

bound upon a centralwooden core, C, asabove described, and shown by Figs. l and 2 of they annexed drawings, is also a substantially different article of manufacture from, and necessarily has superior utility to, a whisk-brush composed of fifty or a greater or a less number of entire broom-corn whisks Vlike the one representedin Fig. 3 of the annexed drawings,

so bound together by wire er twine either i quently'in brushes of the latter kind the4 utility and durability of the brushes depend upon the inferior strength of the stalk K and of the joints Z, by which the fibers b grow from the stalk; but the durability of my improved brush depends upon the strength of the bers themselves. Andsince it requires a far greater force to break one of the iibers b into two parts than to break off the fiber from the stalk K, and since the force required to simultaneously break in two all the hard, tough, and elastic fibers which grow on a stalk, K, is vastly greater than the force by which the soft and brittle stalk itself can be broken off at thepart where thefibers b grow from it, it is evident that my improved brush is far more durable than a brush made of entire whisks of broomcorn.

Having thus described the construction and distinguishing feature of my improved whiskbrush and pointed out some substantial differences thatrexist between it andthose"hereto` upon the wooden core and forming the whole outer portion of the handle I of the brush, as herein described, and shown by the annexed drawings.
