HAIR CLIPPER Filed May 6 1929 gvwento'o vmzdbwm Patented Sept. 13, 1932 UNITED STATES MATTHEW ANIDIS, F BACINE, WISCONSIN HAIR CLIPPER Application filed Kay 8, 1929. Serial No. 380,620.

My invention relates to an improvement in hair cli pers.

The 0 ect of my invention is to provide a hair clipper wherein an adjustment is proltj vided for changing the cut that is to be made. More particularly stated it is the object of my invention to provide for the adjusts ment of the comb plate of a hair clipper and present to the cutter blade thereof a thicker in or thinner ortion of the comb plate, thus proviolin or a close out or a long cut as desire It is also an object of my invention to rovide means for adjustment of my comb p ate whereby the adjustment may be easily and quickly made but wherein the possibility of accidental slippage or maladjustment is reduced to a minimum. v In the drawing: Figure 1 isa vertical view of my clipper. Figure 2 is a side elevation of my clipper witha portion of the cutting head shown in vertical section.

Figure 3 is a view of the adjustable comb late and associated parts showing the same etached.

Figure 4 is a view of the heel of my cliper. a

P Like parts are identified by the same reference ch racters throughout the several views.

I have shown in the drawing an incorporation of my invention in a power ch per 1 wherein power means acting throug an armature lever 2 fulcrumed about the pin 3 provides actuation for a cutter blade 4 which is caused to reciprocate in co-o erative relation to a comb plate 5 the a justment of which, in reference to the cutter blade, is of primary importance to my invention.

It will be noted that the teeth 6 of the comb plate are tapered and that if the cutter blade 4 is so positioned with reference to the comb plate that the thinner portions of the teeth 00- erate with the cuttin portions of the bla e a shorter cut will e accomplished by the clipper. If a longer cut 1s desired the cutter bla e must co-operate with thicker ortions of the teeth 6 of the comb plate. order to accomplish the adjustment required to make this change, I provide the following mechanism and construction:

As shown most clearly in Figure 4 I pro.- vide in the heel 7 of my clip er a dovetail guide 8 wherein a dovetail p ate or slide 9 is slidably receivable and ocketed under this slide 9, I provide an a justment wheel 10 provided with a cam groove 11.

Mounted in threaded engagement with the slide 9, I provide a hardened screw 12 with a cam follower head 13 protruding from the slide to engage-the cam groove 11, and since the cam groove is eccentric to the pivot pin 14 upon which the adjustment wheel 10 is mounted the plate 9 is caused to move in the dovetail guide 8 when the wheel 10 is rotated. I

I mount my comb plate upon the slide 9 by means of screws 15 and thus bind together the various adjustable parts which include the comb plate 5, the slide 9 and the cam wheel 10 with its follower 13. A,

When the adjustable parts are assembled in conjunction with the remaining parts of my cllpper the cutter blade 4 is spring pressed against the comb plate by means of a grooved plate spring 16 acting upon ball bearings 17 which ride in a guide groove 18. By these means, I guide the cutter blade in its movement which in. order to carry out the purposes of my invention must be coincident with the curvature of the comb late. In the particular clipper shown in the rawing, the comb plate is straight'and I therefore change the oscillatory movement of the armature arm to reciprocatory movement by forming the groove of the spring 16 in a straight line, forming the groove 18 of the cutter blade likewise in a straight line and providing a universal connection between the armature arm 2 and the blade 4.

It will be seen from the above description that the partial rotation of the wheel 10 will cause the cam follower to force the plate 9 in one direction or the other to position the comb plate as desired with reference to the cutter lade 4 without disturbing the power connections or operation of the cutter blade and any degree of adjustment is instantane ously available to the operator without stopping the clipper.

I claim:

1. A clipper including the combination with a cutter blade, of power driven means for reciprocating the blade, a cooperating comb plate having teeth of tapering thickness, and manually operable ad'ustment means for mechanically moving t e comb plate to offer portions of greater or less thickness for co-operation with the blade.

2. A clipper including the combination with a support, of a power driven cutter blade vibratory along a permanent path relative to the support, a co-operating comb plate having teeth of tapering thickness, and manually operable adjusting means for slidabl moving the com plate forwardly and bac wardly along the lines in which the teeth project to offer portions of greater or less thickness for co-operation with the blade, whereby to vary the closeness of the cut without varying the relation of the blade to its power driven and actuating connections.

3. The combination with a clipper frame, of a cutter blade mounted for movement with reference to the frame, a comb plate provided with teeth of tapering thickness mounted contiguous to the cutter blade upon the frame for adjustment with reference to the cutter blade, a cam follower secured to the comb plate and an adjustment wheel mounted for rotation upon the frame and provided with a cam groove to receive the cam follower.

4. The combination with a clipper frame, provided with a dovetail channe of a dovetail plate in the channel, a cam wheel and cam follower mounted respectively on a frame and the plate for adjustably ositioning the late with reference to the rame a cutter Blade and a comb plate co-operativel mounted res ectively on the frame and t e plate, where y the adjustment of the dovetail plate will move the comb plate with reference to the cutter blade.

5. In a device of the character described,the combination with a frame, of a cutter blade, means carried by the frame for reciprocating said blade, a comb plate carried by the frame and mounted for movements of adjustment in a path normal to the path of reciprocation of said blade, and mechanical means for adjusting the comb plate along said path without varying the relation of the cutter blade to the reciprocating means.

6. In a device of the character described, the combination with a frame, of a cutter blade mounted for reciprocation relative to said frame, ower driven connections for actuating the blade, a comb plate mounted on the frame for adjusting movement normal to the path of reciprocation of said blade, and a mechanical actuating device movable by the hand of the operator to effect such adjusting movements whereby the relative positions of the blade and comb plate ma be varied without affecting the relation of the cutter blade to either the frame or the power connections.

7. A stationary blade construction for clippers comprisin means forming a uide for the stationary b ade whereby it may e moved to vary its projection beyond the point of the movable b ade, a stationary blade having means fitting said guide means, said blade and guide forming means having cooperating inclined bearin surfaces, and means yieldingly urging said bearing surfaces together.

8. In a clipper a stationar blade, mount- 1ng means on which said b ade is movable to vary its rojection beyond the point of the movable b ade, inclined bearing surfaces guiding said blade in its movement, and means yieldingl faces together w ereb to prevent vibrations of said stationary bla e.

9. A stationary blade construction for clip ers comprising a supporting base fixed on t e clipper frame, a normally stationary blade carried on said base and cooperating with the movable clipper blade, and means for adjusting said stationary blade to vary its projection beyond the point of the .movable blade, said base being grooved to uide said stationary blade and said blade an base having inclined bearing surfaces wedged together to prevent chattering of said stationary blade.
