UNITED STATES' To all lwho/1lb 'if may concern ofthe Philippine lslandsQresiding at lashington, l.)istrict of Columbia, has invented i certain new and useful Improvements in Electric l'lnir Clippers, of which the following is a specification. I

MyV invention relates to hair cutters, and more particulaiy to motor driven hair cute ters or clippers for use by barbers.

The object of my invention is to provide a device of this character which will by reason of the tapering feature thereof, permit ol free and easy access to the sides of the head between the ears of a person, and be Ainexpensive .to manufacture;

vOther and further.'objects and advantages of the invention will be .in part described proceeded Iwith. y In` the 'accompanying Vdrawings forming part of' this specificationzv l Figure l is a side elevation of the Iinvention; f l

Figure 2 is a fraglnental detail view of the two knives withthe handle removed; Figure 3 .is a top plan view of one ot the knives;

Figure l is a face and end view combined of the'knife shown in Figure 3;

Figure 5 is an enlarged fragmental view Yof' the two knives;

Figure G is a section on line lG--of' Figure 5; i

Figure 7 is a fragmental view of' one oi the knives; and t Figure 8 is a detail view of the cam. Referring more particularly to the drawings, l designates a fixed and 2 aunovable blade provided with coacting cutting teeth 3 and 4 respectively. These blades are connected together at their forward ends, with freedom for relative sliding movement, by means of screws v5, carried by the blade l and projecting through slots 'll in the blade 2, spring washers (i being employed to reduce vibration and consequently chattering.

enclosed within a combined housing and handle 6, and the blade l. is fixed to the housingby means 'of screws 7 and B whieh pass through the sides oi` the hous 1ng,rit being noted that the screws 7 and 8 pass Be it known that LiaoNCIo Dnvin, a citizenv andin part obvious as the lspecification is The opposite ends of the blades l and 2 are PATENT oFFIc'E..

above the cut away or reduced rear portion of' the movable blade 2 and thence into screw openings l2 in the blade l. Alpin 9 carried bythe blade l projects through a short slot l() in the blade 2 and serves to guide asl well as limit the movement oi the latter blade.

i The blade lis formed with a comparatively large opening 13 formed by cutting away the top edge ofI the blade to accommodate a drive wheel or cani l-l'presently to be referred to in more detail. The blade l is also Yformed with inwardly extending lugs or flanges and 16 which serve as bearings for a longitudinally extending shaf't 1T. This shaft, which is adapted to be connected to a suitable source of power (not shown) passes through the end wall 2T of the housing (5, thence through the opening 1S in the l.

flange l5. and into the recess 19 in the flange 1G. A collar 20 fixed to the shaft' prevents withdrawal. Y'

-The blade 2. as previously stated,` fis cut away or reduced at its rearportion. upper edge of this reduced portion is formed The with apair off spaced upwardly projecting lugs 2l' and Q1 between which the drive wheel forram H operates, the latter. being fixed to the shaft l? ,by means of'a pinjQZ passing tln'oughopening in the: cam.v

This cani M is of' spiral shape to the end that, when the shaft 1"? is rotated. the movable blade Qwwill heqcaused to reciprocate, it being"understood that 'as the lcam rotates, it
