LOUIS M. EMMONS, OF RICHMOND, INDIANA.

HAIR-DRIER.

To all whom it may concern:

Be it known that I, LoUIs M. EMMONS, a citizen of the United States, residing in the city of Richmond, in the county of lVayne and State of Indiana, have invented certain new and useful Improvements in Hair- Driers, of which the following is a full, clear, and accurate specification and exposition, being such as will enable others to make and use the same.

The object of my present invention, broadly speaking, is to provide certain specific improvements in hair-driers over that shown and claimed in Letters Patent Nos. 756,842 and 808,645, dated April 12, 1904 and January 2, 1906, respectively, both of which patents now belong solely to me.

The specific objects of my present invention are to provide means for rotating the rollers of my hair-drier independent of the movements of the device over the hair or in connection therewith; and also to provide an auxiliary means for strengthening the spring or increasing the compression of the rollers.

Other objects and particular advantages of my invention will be brought out in the course of the following specification, and that which is new will be correlated in the appended claims.

One manner for carrying out the objects of my invention, and that which in practice I have determined to be the most practical is shown in the accompanying drawings, in which Figure 1 is a face side elevation of my hair drier complete. Fig. 2 is an enlarged detail sectional view, as taken on line 22 of Fig. 1. Fig. 3 is a plan view of the interior mechanism for operating the rollers, the cap being removed. Fig. 4: is an inside face view of the finger-lever for operating the rotation of the rollers, and Fig. 5 is a perspective view of the auxiliary spring.

Similar indices denote like parts throughout the several views.

In this instance numeral 1 denotes the body of my device, which is of suitable form and by which the various parts are supported.

Numeral 3 denotes the handle of the device which is formed of comparatively heavy spring wire forming a loop, the end portions 3 and 3" being arranged substantially parallel with each other; both of said portions pass through said body, in which member 3 is rigidly and permanently se- Specification of Letters Patent.

cured, while member 3 is adapted to be moved toward and from the other member, same being operative in a slot therefor in body 1. Mounted on the end portions of members 3 and 3 are the respective rubber rollers 1 and 5 which are adapted to be normally contacted with each other by reason of the said spring handle. Said rollers 4c and 5 are adapted to be forced apart against the resiliency of the spring-handle, by means of the hand lever 6, operative as shown and described in said prior patents.

I now come to a description of my present invention:

Secured in any manner desired to the inner end of the body of roller 4 and adjoining the body 1, is the bevel-pinion 7, same being revoluble around member 3 but it is not secured thereto. Projecting out from the face of body 1 is a fixed pivot 8 on which is revolubly mounted the bevel gear wheel 9 which meshes at right angles with said pinion 7. Formed integral with gear wheel 9 is the plain pinion 10 which is concentric therewith and through which said stem 8 projects. Also projecting out from the face of body 1 is the fixed pivot 11 around which is revolubly mounted the gear-wheel 12. Said gear wheel 12 has a comparatively large central aperture, also it has a sunken face which extends out to near the gear-teeth, both of which are for purposes herein-after specified. The periphery of gear-wheel 12 is in mesh with the pinion 10. Mounted to one side in the sunken face of gear-wheel 12 is the dog 13 whose point is adapted to swing into line of the said central aperture of the gear-wheel 12 in which latter position the dog is normally maintained by the spring 14.

Numeral 15 denotes a disk to which is integrally connected the finger lever 16, a central aperture being formed through the disk 15 in which fits the pivot 11, and formed integral with said disk 15 and projecting inward in the ratchet 17, and rising from the ratchet and concentric therewith is the collar 18 which is adapted to fit in central aperture of gear-wheel 12 with said ratchet resting on the face of said gear-wheel and with the dog 13 in engagement with said ratchet, the dog being retained in contact with the ratchet by said spring 1 1. Nu-

meral 19 denotes a cap for inclosing said 1 gears, same being placed in position, as in Flgs. 1 and 2, before sald ratchet 1s positioned. After the cap has been placed in position then the collar 18 will be inserted in the aperture of gear-wheel 12, which of course centers the wheel 12 and brings the ratchet to position and also brings the disk 15 in contact with the cap 19, after which a washer 20 is placed on the screw 21 and said screw is then inserted in the end of post 11, as shown in Fig. 2, and also the screw 22 is to be inserted through cap 19 into the end of pivot 8, as shown, which manifestly will retain the parts in operative position as shown in the drawings.

From the above it is apparent that when constructed as above described the complete device will appear as in Fig. 1, in which it is evident that if the tool be held in ones hand, that by placing a finger in the eye of lever 16 that said lever may be operated back and forth, which will result in revolving roller at, for the reason that the dog 13 will engage the ratchet 17 on each movement of lever 16 in one direction, thereby revolving the gear-wheel 12 as the dog is secured thereto. Gear wheel 12 meshes with pinion 10 therefore as the latter is connected to the gear-wheel 9 it also will be revolved. And as gear wheel 9 is in mesh with pinion 7 it also will be revolved, carrying revolubl y therewith the roller 4. Now as roller 4: revolves it is evident that roller 5 also will be revolved, but turning opposite thereto.

Letter A denotes an auxiliary flat spring secured at one end to the edge of the body 1, by means of screws 0 and e, as shown in Fig. 5, and with its free end formed con cave and adapted to press against member 3 or against the hub of roller 5, in order to add to the tension with which the rollers 1 and 5 are attracted together.

Having now fully shown and described my invention and the best means for its con struction to me known at this time, what I claim and desire to secure by Letters Patent of the United States, is-

1. A hair drier comprising a body, a handle terminating in a pair of spring mem bers which pass through said body, a roller mounted on each of said members, a lever for springing said rollers apart, and means for revolving the rollers, which means includes a finger-lever adapted to be moved back and forth.

2. A hair drier including a body, a pair of rollers adapted to revolve and normally retained in contact with each other, a handlever pivoted to the body for spreading said rollers apart when desired, a system of gears connected to one of said rollers by which the rollers may be operated in connection with a finger lever, and a finger lever mounted to the side of the body for opcrating said gears, all substantially as shown and described.

3. A hair drier comprising a body, a spring-handle and a pair of members formed of a single length of wire, one of said members being permanently secured in said body and the other portion being free to be moved toward and from the other member and normally retained in contact with each other by the resiliency of said wire, a pair of rollers each mounted on one of said wire members, means for spreading the rollers apart against the resiliency of the wire, and an auxiliary spring for assisting in retaining said rollers in contact with each other.

In testimony whereof I have hereunto subscribed my name to this specification in the presence of two subscribing witnesses.
