J. DEAN HAIR GLIPPER Filed Oct. 30 .u 1923 Y Fig. 1.
Patented Aug. 5, 1924.
PAINT JOHN DEAN, 0F RACINE, WISCONSIN.
HAIR CLIPPER.
l.Application led October 30, 1923.
To all whom t may concern Be it known thatv I, JOHN DEAN, a citi Zen Vof the United States of America, and resident of Racine, county of Racine, State of- Wisconsin, have invented certain new and useful Improvements in and Relating to I-Iair Clippers, of which the following is a specification.
This invention involves the provision of a sanitary guard Vforming a peculiar base plate for hair clippers; and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanations of the accompanying drawings that illustrate what I now believe to be the preferred mechanicalf expression or embodiment of my invention from among other forms, constructions and arrangements within the spirit and scope thereof. Y
An object of the invention is to provide Vsim-ple means for covering the under surfaces of the comb or bottom blades or plates of hair clippers toprevent contact thereofwith the skin of the person operated on, except wherel necessary toexpose the comb teeth or cutting portions of such blades, and to render such means readily removable` and attachable, for cleansing orA other purposes; and a further Objectis to utilize suchl means to provide hair clippers with a rounded or convexed base or bearing surfa-ce on which such clippers can be easily rocked or tilted during the clipping operation to vary the distancebetween the cutters and skin and hence the length of the hair stubble after the cutting operation.
With these and other objects in view my invention consists in certain novel features of construction or formation, or in combinations and arrangements, as more fully pointed out and specified hereinafter,
Referring to the accompanying drawings Fig; 1 is abottom plan showing a hair. clipper (partially broken away) equipped with my invention.
Fig. 2 is an end edge elevation of thel constructions disclosed by Fig. 1.
Fig. 3 is a top plan of the disclosure of r'g. A. is a section' on um une 4 4, Fig. l, but showing the comb blade and guard only on an enlarged scale.
Sera1` No. 671,718.
Fig. 5 is a section on the line 5 5, Fig. 1, but showing the comb blade and guard only on an enlarged scale.
Fig. 6 is a detail perspective View of the base or face plate and protective guard of my invention.
The hair clipper shown, embodies flat comb or bottom blade or plate 1, and flat top or reciprocating cutter blade or plate 2. The bottom or comb blade 1, is formed at its front edge into the comb cutting teeth la, of the clipper, and the front edge portion of upper blade 2 is formed into cutting teeth 2a, that cooperate with comb teeth la, in the usual or any other suitable manner to cut or clip hair. The comb blade 1, is flat at its under surface, except for the front edge bevel lb that forms the comb teeth la, with an upward and forward bottom edge taper, and except for the fore and aft ridges or corrugations 1, in longitudinal rearward extension of the lower edges of teeth 1, respectively.
The comb or bottom blade 1 is secured as by screws (not shown) to, and is arranged below, the main supporting body or frame 4L, from which the rigid handle 5 projects. The swingable spring pressed operating handle 6, is pivotally mounted to or on the body 4 and is operatively coupled to the upper or reciprocating cutter blade, to actuate the same.
The comb blade l, intermediate its front and rear edges, is formed with a top groove 1e that extends through both end edges of said blade. f
Holes for the screws that secure the comb blade and for other screws securing certain lugs on the top face of the comb blade, extend through the under surface of said blade, in the usual type of hair clipper.
The hair clipper shown, and as thus far described, is well known to commerce and to those skilled in the art. These clippers now in common use are objectionable from the sanitary standpoint, in that the bottom surfaces of the comb blades come in direct contact with the moist skin with a resulting action on the exposed surfaces of the comb blades that tends to roughenthe same by corrosion, rust or otherwise. The bottom surfaces of the blades thus tend to carry infection particularly as the rougliening thereof prevents proper wiping and cleans-ing of blade, also tend to present objectionable sharp edges as well as leave cre-vices for the collection of filth and germs. Also, the flatA bottom surface of the comb blade rendersit difficult to feather off the hair, by tilting the clipper on the skin to vary the distance between the skin andthe cutting points, as will be well understood by those skilled in the art.
I have successfully solved the problem of overcoming these difliculties by the provision ofa. peculiarl sanitary guard, face or base plate, which in the particular embodiment illustrated as an example for purposes of explanation, is struck or pressed up in one piece from thin elastic orv spring nonrusting non-corrodable sheet metal or of other thin spring sheet metal such as brass or other metal, coated or plated with nickel or other suitable metal to provide smooth non-rusting noncorrodable exposed surfaces. This guard is designed to cover the rear or heel edge of the comb blade of the clippers, the major portions of the lengths of the end edges of said blade, and the entire bottom surface of the blade upto the Y bases, of the comb teeth, i. e., up to the bevel ofthe front end of the comb blade, and the bottom or body of this guard is arched, convexed or rounded downwardly from its front edge to its rear edge to provide a bearing surface on which the hair clipper can rock and slide to elevate the cutting teeth to the desired elevation from the skin and maintain them at such elevation during the hair cutting operation. Y
This thin spring sheet metal guard forms the bottom plate or bodyVlO of dimensions to Ventirely cover the comb blade at least up to the front bevel thereof, and this body i0 is` formed with the upstanding flange llwhich is continuous around the body plate 10- from one endv of the front edge l2 of said body plate to the opposite end Aof said front edge. The guard is thus open or no nflanged at its. front end and the front edge l2 is straight. The upstanding flange ll is designed to extend upwardly at the exterior of and cover the otherwise exposed rear and end edges of the comb blade and to maintain the guard properly positioned on said blade against relative forward and endwise movement. ln this example, the flange covers the blade ends except for the upwardly beveled front ends thereof. The end portions of the flange are formed with upwardly projecting inwardly deflected or indented spring retain ing projections, tits or lingers 13, designed to snap over the top faces of the end por- The screw heads and ends that are tions of the blade to detachably retain the guard in proper position Von theblade.
These spring fingers 13, inthe example shown, are arranged to snap into the depressionsl inthe blade ends formed by the top groove le, and lap over the floor of said groove and thus normally hold the guard tightly up against the bottom of the blade and against sliding rearwardly from theV guard fit into or intermeshv with the approxi-V l mately similar ridges or corrugations on the `bottom face of the blade. The body plate ofthe guard is concavo-convex Vfrcmfivi'ro-nt to rear to form the downwardlyarched or; conveXed bearing surface and .consequently the top face of the vbody plate ofthe guard fitsror engagesV the under face of thecomb blade only at the rear. edge lportionthereof;`
and the beveled front edge portionthereofrr.
The front straight edge portion of the body plate of the guard is inclined upwardly; and
forwardly andlaps overY onto and fits the, beveled front edge portion of the comb' plate; approximately in the direction andatthev angle.V of the' bevel so as to form an approximately smooth joint therewith and,y
rearward continuation atV same angle as the bevel.'
Those slrilledrin the art willappreciate, the utility and advantages of this guard4 without necessity of further detail explanaf tion. a
It is evidentthat various changes,Y departures, and modifications might be resorted to in the forms and constructions de-V scribed without departingffrom theU spirit and scope of my invention, and-hencel do not wish to limit myself tothe exact dis` closure hereof.
YWhat l claim is: j j
l. A sanitary` guard for the combi .blade of a hair clipper, struck up from thin vspring sheet imetal providing a bodyV plate convened from its front to its rearedge, to cover theV bottom face of the comb blade rearwardly from the fronty edge bevel thereof and having an upstanding flange ll to fit-the end and rear vedges of the blade. Y
2. A sanitary guardffonthe comb plate of a hair clipper formed to cover the bfottom face of the Vblade fromthe frontedge portion thereof. rearwardly, fandV having means for removablyY attaching the guardto .approximately the lOO tions or ridges coinciding at the front edge of the guard with the corresponding corrugations or ridges on the under side of the comb blade.
