Specificationof To all whom it may concern: 1 t

-Be it known that L SAMUEL Snvnnson, a citizen of the United States, and. resident of Valders in the county of Manitcwocand State of Wisconsin, have inventedfcertain new and useful Improvements in Hair-Cutting Appliances; and 1 do hereby declare that the following is a full, clear, and exact description thereof.

My. invention relates to new and useful improvements in hair cutting appliances'of that type in which the cutters are mechanically operated. v s

It is in general the object of this invention to rovide a very. simply constructed and rea ily manipulated hair cutting appliance which is capable of trimming hair to any desired length and for cutting any length of hair with great facility.

I-t'is also an object of the invention to provide a device of thischaracter having cutting members Which can be automatically shifted to cut hair oftdiiferent lengths, or which can be retained stationary to trim hair of the samelength. f i

Still another-object of the invention is to provide an appliance of this nature having means for evenly. drawing; the hair to be out into range of the cutting members. I

With these general objects inview the invention consists in the novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and claimed. I

In theaccompanying drawing: to

Figure 1 represents a longitudinal sectional View taken substantiallyon the plane .of the line 1 1, of Figure 2.

Figure 2 is a part side elevational and part sectional view of the appliance.

Figure 8 is a transverse sectional view through the gear h0using, and

Figure i is a similar sectional view taken on the plane of the line 44 of Figure 2.

In the preferred embodiment of the invention as illustrated in this drawing, the reference character 1 denotes an elongated sub stantially rectangular casing, open at both ends and having its sidewalls at its intake end extending beyond the adjacent edges of the other walls to provide spacing fingers 2. Theoppoiste end of the casing is closed by a removable cover 3 secured thereto by screws or the like 4. The cutter comprises a carrying plate 5 slidable in the casing 1. and engaging the inner surface of the several walls thereof, a relatively stationary cutter n: Patented July is, race.

bar 6, and a reciprocable cutter bar As is customary in this type of

cutteuthe bars

6 and 7 are provided along one longitudinal edge with"co-operating' cutter teeth 8 and 9, the flatter being shifted into and out of alinement with the teeth 8, upon reciproca tion of the cutter bar 7. The last mentioned cutter bar is disposed between the carrying plate 5 and the stationary cutter bar 6 itbeingheld in operative position with respect thereto by retaining bolts 10, the

same extending, transversely through the several parts of the cutting member and hav mg nuts 11 on their threaded ends. Springs 12 are locatedbetween the carrying plate 5 and the inutsll to. procure a yieldableo enj gageinent betweenlthe ,cutter bars and the plate The carryingplate 5 also provides a hearing 13 for one endvof a feedshaftl i which extends longitudinally through the casing l and has an eccentric 15 at one end 'dlSPOSGCl in an opening in he cutter barq.

Thus rotationof. the shaft 14 turns the eecentric and reciprocates thebar '7, this being permitted in view' 'of the bolts 10 being disposed in the slots 10. o f H The end portion ofthe feed shaft l l 0pposite the end carrying the eccentric 15 is rotatably journaled in the cover Sand isv slidahle' longitudinally through the hub 16 of a WOIIl'l gear--17, the sameobeing splined thereto by means of a-f'eather and the key groove 18. y The worm gear 17 is rotatedby means of a, worm 19 formed on the stub shaft 20; the latter extendingtransverselyof the casing 1; andhavinga suitable flexible shaft 21 1 connected thereto forrotation from a suitable source of power. The hub 16-of the worm gearl isjournaled in a bearing carried by a wall'92 which partially defines a gear housing 23, one side ofsaid housing being closed bv said rover 8and two'of the other sides by the walls of the casing 1.

i From this construction it will be seen that rotation of the stub shaft 20 causes the feed snaft i lto be revolved with a. consequent actuationnf the cutter bar'T. The rotation of the feed shaft 14: isused for movmg 1 so as to shift the cutter member inng the parts the gear housing23' contains a slidable feed plate'24, o. e end of which is bifurcated and hasthe shaft 14 disposedbetween itsfurca tions and adapted to he engaged by a thread portion 26 at the will of the operator;

5., 6 7. In other words the sane longitudinally through the ca The opposite or outer end of the plate 241. extends through an opening in the casing 1 and is bent laterally to provide a finger piece 27. An expanding leaf spring 28 located between the finger piece and the adja cent wall of the casing 1 normally urges the teed plate outwardly to disengage the thread portion 26 from the threads of the feed sha'it l l. During such disengagement the shaft 14 merely rotates and the cutter member is held against shitting longitudinally of said casing. On the other hand, as soon as the operator forces the thread aortion 26 into engagementwyith the threas of the shaft 14, the rotation of the latter causes the same to be fed outwardly of the casing. In Figures 1 and 2 the shaft has been partially fed from, the casing to space the cutter member inwardly otthe intake end of the latte: r. ;ks shown in Figure 1 the feed plate 24: is slidable in guides 29 carried by the cover 3. i p

The casing 1 adjacent the closed end thereof is provided with a suction tube attaching nipple 30 whereby the interior-t the easing may be subjected to the action of a suitable vacuum mechanism (not shown.) That is to say by such an arrangement air is drawn through thecasing from the open end thereoi and through the cutter member. In order that this air may be drawn transversely across the cutter bars throughout the length thereof, the carrying plate 5. is formed with a longitudinally extending intermediately located suction slot 31. This slot is positioned inwardly of the innerends of the teeth 8 and 9 so that the air entering the casing 1 is deflected with a result that the hair. is positively drawn throughthe teeth 8 and 9. As indicated at 32 the portion of the carrying plate adjacent the teeth 9 is cut away to'readily permit said hair to enter the slot 31. The carrying plate 5 also has friction elements 33, disposed in its ends for engagement \viththe side walls of the casing 1. such an arrangement being conducive to a more eflicient operation.

In the use of my. invention, the operator starts the rotation of the worm shaft the same being connected to the flexible shatt of said suitable source of power, whereupon the cutter will reciprocate continuously, If short hair is to be cut, the cutter member is located at the extreme open end ot the casing 1 between the lingers 2, and as it is desired to cut less and less hair, the cutter member is progressively moved into the casing merely by pressing upon he finger piece 27. However, ita particular length of hair is desired, the cutter member is moved into the casing a suitable distance and permitted to operate in this position as long as necessary, the feed plate 24: under such conditions being inactive.

Although the the invention is above described,

preferred embodiment of shown in the drawing and it is to be understood that various changes may be madein the difi erent parts of the appliance and in the proportions or its parts, withoiit departing from the principles or sacrificing any of the advantages thereof.
