invention relates to vshaving or clipping' devicesof `the type used withoutl the aid of soap, water and the like, and has among its objects and advantages l the`provis`i-onf` of an improved multiple Ihead dry shaver.`

The `.cutters [8 are V.provided `witlrg` slightly 5" spirally directed slots extending cireumfer lentially of the respectivecutters throughout substantially onehundred andeighty degrees.` The throughout their entire areas with the exception. of the flared ends 2U." The perforations orslots 4 8 inthe tubes I Gare shortbut-arranged in slight overlapping relationship and. slightly spiraled but reversely withrespect to the slots t6.` Means for reciprocating the, tubes 8 comprise: two `bars .illslidably` guided inbeari'ngs 52 atetched `to an4 ond' wan 54 of the body mi` The two bars 5U aref arranged in parallelism and are simultaneously;reciprocated in opposite directions i by a link' 55 pivotallymounted on a bolt 58 attached to the wall till.A "All the` bearings `52 are 5l?` secured to the end wally j attached,` to a plate Each bar- 5U is provided with a pin 62 projecting into a slot 64 in the link 5t; One end of the link.

is `'promoted with a Apivot; tsj retained between ngers' 68],at one end of a lever TU. `'lfhis Ieve'r is mounted for oscillation on `a supporting bolt 'I2' attached to the body IU'. A fork T4 is carried `by the arm 'lll and connects ,with an eccentric` TE, fixed to arnotorfdriven shaft; "Thus rotation.`

of` the eccentriclt" `imparts oscillatory` motionk to the arm T0.` Such oscillatory motion of the 3 arm T0 is transmittedto the link `56 so that the bars' 50` are simultaneously reciprocated'gin op`" 3x5 posit'e directions. 1

Bothbars 50 are bentback` uponlthemselvesiat 8IJ `to provide arms,` 82 extending. inside `there- `spectivo tubes la, the tubes having iongiindium` groovesl 841 intheir inner wall `faces for housingthe arms Y82'. and the lower side Vof the ange'fl is cutaway to provide a necessaryclearance above. 1 the complementaliiared ends .211',` of. the tubes l`6,.

for the reciprocating movements of the arms 811. Each arm is provided with anopeningli to re,`

Cleaning doors 38 are slidably mounted on the Figure 1: by means of screws 36,.

Both tubes IB are provided with longitudinally` i extending flattenedfaces 92, which faces lend thinnessto the tubes sothat closer cuts may be `made.` Both 'tubes I6`rotatef freely and are so and opening the nanges 24`and `26. Grooves 44 55 ttedlontheir respective tubes I8 as to perform facilitated byreason or `their up#-V Aturned ends Btlr an efficient hair cutting function. The slots in the tubes I8 are oppositely angled With respect to the slots or perforations 48 in the tubes I6.

In view of the rolling nature of the tubes I8, the slots in the tubes fall over the hairs to facilitate entry of the hair being cut'. Vibration is reduced because of the alternately actuated tubes I8. Less pressure is needed on the cutter heads, since the rolling tubes I6 facilitate entry of the hair. The doors 38 may be easily opened to facilitate cleaning` of the head structure. The outer cutter cylinders or tubes I 6 have polygonal outer surfaces in order to facilitate the passage of` the hairs through the openings thereof and A starting disk sa is fixed o theshaft 1a` for the purpose of starting the motor at times when its contacts are such las to break the circuit. Such motors are old and welll known inthe art. Without further elaboration, the foregoing will so fully explain my invention, that others'may, byapplying current knowledge, readily adapt the same forl use under various conditions of service.
