SIDNEY P. JONES, OF HACO,v TEXAS, ASSIGNOR TO THE -JONES ELECTRIC CORPORA- TION, OF WACO, TEXAS.

SHAVING MACHINE.

Application filed February 8; 1923. Serial No. 617,756.

To all whom it may concern.

Be it known that I, SIDNEY P. Jones, citizen of the United States, residing at Waco, in the county of MeLennan and State of Texas, have invented certain new and use ful Improvements in Shavin Machines, of which the following is a specification.

This invention relates to new and useful improvements in shaving machines.

The ob'ect of the invention is to provide amechamcal device for removing the beard from the human face in a simple, expeditious, convenient and comfortable manner.

A particular object is to provide a power operated machine or device which will be substantially free from perceptible vibration' and which will function efficaciously and without causing irritation or pulling of the hairs.

An im ortant object of the invention is to provi e a shuttle-action cutting blade which will cut thru the hairs in a diagonal direction when the device is moved over the face in a substantially straight line, thus 2 giving an easier and faster cutting action than can be had with an ordinary straight edge or safety razor. I

Another object is to provide (a shaving device in which the shaving head may be moved in reverse directions while in contact with the face so as to shave'in both directions in a nick and easy manner; and

in connection with this feature is the provi sion of means for producing sucha rapid 5 and smooth shuttle movement of a two edge blade, as to preclude any unpleasant or irritating results. I A still further object is to provide a cutter head arran d to accumulate and hold the lather whic is removed from the face, thus obviating the necessity of the use of paper or stopping to remove the accumulated lather. until the shave is completed.

Another object of the invention is to shuttle a two-edge blade, between guard mem bers, whereb either blade edge is free to cut the bear without overlappingvor overlying the guard members.

v A further object of the invention is to provide a shaving device in which the blade may be readily removed and replaced and easily cleaned. 7

form longitudina lather holdin A construction designed to carry out the invention'will be hereinafter described together with other features of the invention.

The invention will be more readily understood from areading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Fig. 1 is a side elevation of a shaving machine constructed in accordance with my invention,

Fig. 2 is a frontelevation of the same, Fig. 3 is a longitudinal vertical sectional view of the same,

F ig. 4 is an elevation of the h'e'adwith the guardplate swung down to expose the blade,

Fig. 5 is a similar view with the blade and carriage removed, Fig. 6 is a plan view of the machine,

Fig. 7 is a cross sectional view on the line 7-7 of Fig-8, I

Fig. 8 is an enlarged longitudinal sectional view of the head,

Fig. 9 is an enlarged fragmentary crosssection of the head, blade and carriage, and

Fig; 10 is a perspective view of the carriage. i

In the drawin the numeral 10 designates a tubular han e having a head 11 at its upper end which is provided with a laterally offset bracket 12 extending longitudinally of the handle and head. Thebraeket is reduced in thickness to, provide a web extending radiall from the head and to channels or pockets 13 'on each side. Guar members composed of transverse teeth 14 are disposed along each side of the face of the bracket the teeth overhangingthe channels and the spaces between the teeth forming entrances to the channels for the passage .of the lather.

The face of the bracket has a pair of lon- Y gitudinal grooves or trenches 15 contiguous to the teeth and a air of spaced grooves 16. substantially para el thereto (see Figs. 7 and 9). Between each groove 15 and its correlated groove 16 is formed a longitudinal runner or track 17. 'Longitudinally of the center of the face and, between the grooves 16 is formed a longitudinal central.

- rest entirely upon the tracks and free contact with the boss or other parts of the face of the bracket and while evenly supported g I X boss 18 having its surface below the surfaces of the tracks 17. Thusa cutting blade 19 mounted on the face of the bracket may as is'the practice in this art, said teeth being The cutting edgesas narrow as the spaces.

' of the blade are contiguous to the inner ends of the teeth and,overhang the grooves 15, whereby said edges are unobstructed, which is not the case where cutting edges overlap or overlie guard teeth. The cutting edges and the inner ends of the teeth being in sub"- stantially the same vertical plane and nearly coincident, a veryv safe and eflicacious cut-- ting action is had when the blade is shuttled or reciprocated longitudinally.

The blade is covered byva guard plate 20 *which a bushing 33 mounted in the upper having a hinge lug'21 at its lower end hinged between cars 22 at the bottom of the bracket. The plate has a stud 23 projecting from its upper end engaging a spring latch 24 fastened on the bracket (Fig. 8). The. under side of the plate is dished longitudinally except at its'ends so that its marginal edges bear up the blade and hold the latter upon the tracks 17. By springing the latch the plate may be qu-ickly swung down (as in Fig. 4) to expose the blade 19. The blade is of such width as to expose the cutting edges of the blade which project beyond the edges of the plate. The outer surface of the blade.

is curved transversely, conforming generally to the curvature of the teeth, so that when 'the plate isgpressed against the skin it may be rocked to either side to bring one of the cutting edges into contact with the heard. The plate provides a smooth guide or shoe for running the machine over the face.

The amplitude of the shuttle action of the blade may be confined within a fraction of an inch, "a movement of substantially onethirtysecond of an inch having given satisfactory results in an extended period.of experimentatiomhowevei' the amplitude may be varied in accordance with the design of the machine.

Various means are obvious to those skilled in the art, for actuating the'blade and it is possible to-use many well known movements. I have used and here illustrate a shuttle carriage operated by an eccentric 'wheel, but even; it is subject to variation. The carriage comprises an elongated carrier 25 which is substantially rectangular in crosssection and fits snugly in a slot 26 extending inwardly from the face of the bracket, the slot connectingwith a longitudinal bore 27 in which a cylindrical ,carriage 28 is. mounted to slider The carrier has its underside concaved to fit on the carriage and is fastened to the latter by a screw 29 and a screw post'30 projects from the carriage thru an aperture er end -of the carrier has an overhanging lip 32 (Figs.8 and 10) and in placing the blade,'the latter is tilted to first receive said lip and then is slid upwardly and pressed down on the shoulders. A turn button 32 is counter-sunk in the carrier and suitably shafted to ride out over the blade when turned crosswise.

The lip and button act a to hold the blade rigidlyon the carrier and r firmly u on the tracks 17 The blade may be quic y removed and replaced.

The head has an enlarged cavity 11' into portion of the handle rojects. This bushing is held in position y a set screw 33 or other means. A second bushing 34 is held in the handle by a set screw 34' or other means.- A longitudinal sh'aft 35 extends thru the bushings and is rovide'd with a pairof spaced collars 36 isposed between the bushings and abutting the ends thereof, whereby the shaft is held against longitudinal displacement. The upper end of the shafthas an annular groove 37 and rojects into a bearing in the under side 0? a cap 39 confined in the upper 'end of the cavity 11' by a screw 38, the inner end of which extends into the groove 37.

On the shaft is mounted an eccentric wheel comprising a sleeve 40 and a pair of disks or annular flanges 41. The sleeve is its suitably fastened upon the shaft with its lower end resting upon the upper end of the bushin '33, whereby end thrust is eliminated. e co-acting or adjacent sides of the flanges are dressed at an angle to transverse and when revolved, impart a shuttle motion to the' carriage thru the agency of the roller 42 and post 30.

The degree of inclination with respect to the transverse axis of the sleeve, which is given the sides of the flanges, is slight and is exaggerated in the drawings, as only a limited reciprocation of the b ade is necessary. By. revolving the shaft3 5 at say seventy-five hundred R. P. M. the blade is shuttled rapidly and owing to the Short amplitude of its movement and the firm manner in which it is supported and guided,

substantially no vibration is'felt when using the machine.

The lower end of the shaft 35 is finished to receive the end of a flexible shaft 44,

44 is held in engagement with the shaft 35.

A boss 46 (Fig. 3) cast on the side of the handle receives a set screw 47 which bears against a coiled spring 48 confined in the boss which has a bore for receiving said parts. The inner end'of the bore is reduced to less than the diameter of the ball 45, so While the spring pressed the ball into the bore of the handle, said ball is-still retained in the bore of the boss In using the. machine the beard is lathered in the usual. manner and the machine started which is accomplished by attaching the handle to the flexible shaft 44, the latter being driven byan electric motor or other source of power (not. shown). It is of course withln the province of the invention tomount an electric motor (not shown) in the handle 10 for the purposeof revolving the shaft 35. The shaft 35 being set in motion causes the blade 19 to shuttle by reason of the reciprocation of the carriage 28by the flanges 41. The operator grasps the head 11, the channels accommodating the fingers and thumb of the operators hand. If desirable a knurled grip '49 may be formed on the head at the lower end of one of the channels for the thumb. The machine is held transversely 'or at right angles to the rocking the head on t e plate 20 the uppermost teeth and cutting edge arebrought nto contact with the beard and a reverse stroke may be made upward of the face. \{arious strokes may thus be executed and the shaving operation carried out in an expeditious, satisfactory and pleasing manner.

As the shaving proceeds the shuttling of the blade will be so rapidthat its movement will not be felt upon the skin. The head being moved ina straight line the rapidly moving blade will cut diagonally, thus carrying out its, work without pulling or irritation. As the lather is removed a together with out, hairs it passes between the port between the guards, a radial web exlongitudinall teeth 14 and into thechannels-13 which are ample enough to accommodate a full' shave. When the shave is finished the machine may a be subjectedvto a stream of hot=water for cleansing. 10
