AUSTIN A. SMITH, OF SENECA FALLS, NE7 YORK.

.lNiPROVEMENT IN INJECTOPLS FOR THE HAIR.v

Specification forming part of Letters Patent N0. fil-L84 3, dated October 25, 1864.

To all whom it may concern Be it known that I, AUs'riN A. SMITH, ofj Seneca Falls, in the county of Seneca and 5 State of New York, have invented certain new and useful Improvements in Injectors for the Hair; and I hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this speciiication, in which-- Figure l is a plan view of my improved ini strument. Fig. 2 is a side elevation. Fig. 3 is a longitudinal vertical section on the line a' Fig. 4 is an enlarged section on the line i 1/y. Fig. 5 is an enlarged section of one ofi the distributing-tubes D.

Like letters of reference indicate corral spending parts in all the gures.

My improved injector is designed for applying water, oil, or other fluid to the hair and scalp in a more convenient and ettectual manner than has heretofore been done.

It consists of a vacuum-bulb for receiving and expelling the uid, provided with a series iiexible neck, C, or from the elastic side of; the bulb itself. The bulb is constructed of i an annular V-shaped or convex rim, A, (shown most clearly in the sections, Figs. 3 and 4,) of india-rubber or other elastic material, with l rigid sides or plates B B, which may be made l of wood, ivory, or other non-elastic substance, i connected with the rubber rim by a joint that l is tluid'tight.

A convenient mode of forming the joint is by grooving the edges of the plates B and; stretching the edges of the rubber rim A f (which should be of alittle smaller diameter) over these grooves, when the contraction of i the rubber will keep the joint tight, and sepi aration may be prevented by winding with* thread or wire at b. Any equivalent method i of fastening may be used..

The form of the bulb may be round or oval, the latter being preferable for convenience.

Connected with the rim A, or formed, as it is made, of the same material, is a neck, O, in the head of which are aliixed the distributingi tubes D D. These tubes being individually distinct, and only held together by the'indiarubber connection, will yield or bend backward from their position by pressure, either singly or together as shown by the red lines L of Fig. This allows them to conform to the shape of the head in any position in which the instrument is held when used, and remain in their normal position at other times. The tubes D may be connected directly with the rim A, with the same or nearly as good an effect.

The V-shaped or convex form of the rim A causes it to act on its contents when the sides y are compressed, by closing the angles of the i inner rounded or swelled surfaces, c c, to-

gether, and consequently gradually shutting the water from the angles, forcing the co11- tents into a smaller area between the two plates B B, and more eii'ectually expel vthe l iiuid than can be done where the bulb is of india-rubber entirely, when it is diflicult to compress it equally, the center collapsing,

` while the outside is filled with and retains the fluid. rIhe red lines in Fig. 4 show the effect of compressing the rigid sides of the bulb by closing together the angle of the rim. rIhe combining of the rigid side plates, B, with the l elastic rim A also renders it more convenient of distributingtubes, D D, di'verging from a l to handle and work than Awhen the whole is elastic, for these press equally and nnyieldingly toward each other without any central collapse, and thus force ali the iiuid out without requiring the bulb to be compressed by V the hands over its whole surface.

The tubes D are made hollow, but closed at the ends, and provided with an educt'ion-orifice,- d, near the end and on the inner or concavev side, they being slightly curved. The ends are closed and made perfectly smooth to prevent catching and pulling the hair or scratching the skin, and to prevent the oriiices y becoming filled up, as they soon would be.a

with dandrutt', and the passage of the ud prevented. By being on the sides the holes may be elongated to give sufcient size without increasing that of the tubes, and they dislcharge the fluid directly down upon the skin,

so that by pressing firmly the contents may,

iif required, be applied to the skin without coming in contact with the hair, which is sometimes of importance in treating diseases of the scalp with prel'iarations that would injure the hair.

Another important advantage is obtained from the side orifices of the distributers-n viz., that where oil or other prepa-ration is applied to the hair it cannot be discharged out- 1. Forming,` the elastic rim A with its sides a a, so situated and formed that compressing the sides Will gradually close the vacuumchamber from the angle of the periphery inward toward the center, so as to expel all the fluid, substantially as set forth.

2. Constructing the vacuum-bulb with rigid sides or plates B B, in combination with the elastic ring A, substantially in the manner and for the purposes described.

3. In combination with the flexible vacuumbulb A B, the series of distributing-tubes D,

so constructed as to inject a fluid beneath the hair in small jets, substantially as set forth.

4. The hollow teeth or tubes D, formed with the eduction-orice d on the under concave side thereof, to prevent the same from becom-v ing obstructed, and to direct the lluid downward upon the scalp, and to prevent scratching` or tearing, substantially as set forth.

5. Making the neck or base to which the tubes D are attached flexible, so as to render them capable of bending separately or together to adjust themselves to the form of the head in Whatever position they may be applied, substantially as set forth.

In Witness whereof I have hereunto signed my naine in the presence of two subscribing` witnesses.

AUSTIN A. SMITH.
