Application illed April :4, 1919. Serial No. 298,445.
To all whom it may concern:
Be it known that I, LEWIS J. Breann- DAHL, citizen of the United States, resldmg at 506* Capitol street, Vallejo, in the county of Solano and State of Cahfornia, have mvented certain new and useful Improvements in Hair-Cutters, of which the followin is a specification.
liy invention relates to new and useful improvements in hair cutters, and more particularly to the type employinv a safety razor blade in conjunction with a guard member.
An important object of my invention resides in the provision of a device including a cutting element adjustably associate with a guard member having comb teeth therein, whereby the cuttin edge of the cutting element is adjusta 1y associated with the comb teeth.
Another object of m in the provision of a evice of the above mentioned character embodying means whereby the cutting element may be retained 1n various adjusted positions.
A still further object of m invention resides in the provision of a evice embodying a pair of sets of comb teeth between which is mounted a cutting element, thereby preventin the users fingers from cut by the sharpened edge of the cutting element.
A still further object of my invention resides in a provision of a device of the above mentioned character which is strong, durable, inexpensive to manufacture and one which is eilicient in practice.
A further object of m invention resides in the provision of a evice as above set forth embodying a guard member which is constructed from a single piece of metal.
Other objects and advantages of the invention will become apparent during the course of the following description.
In the accompanying drawmg forming a part of the description and wherein like numerals are employed to designate like parts throughout the same,
Figure 1 is a front elevation of my invention.
Fig. 2 is a longitudinal section.
Fig. 3 is an end view of Fig. 1, and
F' is a transverse section taken on th; lme1 4-4 of Fig. 1. dm h n t e accompanying wings, w erein is shown a preferred embodiment of my ininvention resides is provided with a longitudinally extending slot 9, and the portion of the walls 6 and 7 which form 0 posite sides of the slot 9, are bent outwar ly as indicated b the numeral 10, for a urpose which wil appear hereinafter. he lower edge of each Wall 6 and 7 is provided with a plurality of comb teeth 11, and by this construction it will be seen that a pair of sets of comb teeth are carried b the guard. As more clearly shown in Fig. 1 of the drawings, the comb teeth of the two sets aline so that the teeth may be readily passed through the users hair. Each wall 6 and 7 is provided with an elongated opening 12 substantially intermediate the upper and lower edges of the guard and in such a manner that the openmgs aline, so that the user may gain access to the upper edge of the cutting element 13. As more clearly shown in Fig. 2, the ends of the openings 12 engage the ends of the cutting element whereby the latter is roperly guided.
he cutting element embodied in my invention in this particular instance, is in the form of a razor blade, the lower portion of which, adjacent its cutting edge, is received between the two sets of comb teeth 11. In order that the blade may be held in any desired adjusted position with relation to'the comb teeth, I provide a pair of bolts 14 or the like, which extend through and beyond the walls 6 and 7 adjacent their lower ends to receive nuts 15 upon the threaded ends thereof. Accordingly, it will be seen that when the nuts 15 are screwed upon the bolts, the two sets of comb teeth are drawn toward each other to snugly embrace the cutter element 13 and retain it in any desired adjusted position.
The means I employ for adjusting the position of the cutting element 13 consists of a segment 16 pivotally mounted in the slot 9 between the outwardly bent ortions 10 of the guard by means of a be t 17 passing through the outwardly bent portions 10 and the segment and extending beyond one wall of the outward] bent portion 10 to receive thereon a nut 8. A link 19 is pivotally connected to the segment 16 adjacent its petion of t ripher while the othemend of the link is plvota 1 connected to the intermediate poriie cutting element. As more clearly 3 and 4 of the drawings, of a pair of spaced arms by a bridging porshown in Figs. this link consists held in this relation tion 20.
In use, the segment is moved upon its pivot so as to either raise or lower the cutting element b the link connection 19 until the cuttin e ge of the cutting element is arran in its proper relation with the comb teet 11. The nuts 15 ma then be tightened upon the bolts 14 to raw the walls 6 and 7 of the sets of comb teeth in close engagement with the cutting element to retain it in its adjusted position. The guard is then grasped in one hand by the user and run through the hair as a comb and the best results are obtained. Of course, by adjusting the cutting edge of the cutting element 13 adjacent the lower ends of the comb teeth 11, the cutter will clip the hair short, while by an opposite adjustment the cutting edge is arranged a substantial dis tance above the lower ends of the comb teeth and will cut the hair longer.
The foregoing description and the drawings have reference to what may be considered the preferred, or approved, form of invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, etc., as may prove expedient and fall within the scope of the ap ended claims.
avin thus fully described my invention, what I cfixim as new and desire to secure by Letters Patent, is:
1. A hair cutter comprising a guard having comb teeth, a cutting element adjustab y mounted upon said ard, a member pivoted to said guard, an a link pivotally connecting said cuttin element and said pivoted member for a justing said cutting element with relation to the comb teeth.
2. A hair cutter comprising a guard consisting of a single iece of material folded upon itself to provi e a pair of spaced walls the lower edge of each wall being provide with alined comb teeth to provide a pair of sets of teeth, a cutting element adjustably mounted between said sets of teeth, a segment ivotally mounted in the upper portion 0 said guard between the spaced walls thereof, and projecting above the top of said guard and a link pivotally segment and to said cutting element, whereby the cutting element may be adjusted with relation to said teeth.
3. A hair cutter comprising a guard having comb teeth, a cutting element adjustably mounted on said guard, a member pivoted to said guard and having connection with said cutting elementfor adjusting the same with relation to the comb teeth.
4. A hair cutter comprising a guard having comb teeth, a cutting element adjustably mounted upon said guard, a segment PIV- otally mounted upon the upper portion of said guard, and a link pivotally connecting said se ent to said cutting element whereby the atter may be adjusted with relation to said comb teeth.
In testimon whereof I aflix my signature in presence 0 two witnesses.
