DAVID JOHN'ARCHER, OF TORONTO, CANADA.

HAlR-CLIPPER.

PECIFICATION forming part of Letters Patent NO. 657,074, dated September 4, 1900. Application filed December 23,1899. ISerial No. 741,390. N modelJ To allwhom 2125 may concern:

Be it known that 1, DAVID JOHN ARCHER, barber, of the city of Toronto, in the county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Hair-Clippers, of which the following is a specification.

My invention relates to improvements in hair-clippers and the object of my invention is to provide suitable means for operating the cutter-bar of the ordinary hair-clipper much quicker than is ordinarily the case and also to enable the operator to move the clipperin any direction over the head and cut the hair; and it consists, essentially, insuitably attaching to the cutter-bar a pivoted reciprocating arm and providing suitable means for operating said arm and attaching a suitable device to and inclosing the cutter-bar and knife to enable the hair-clipper to be moved in any direction over the head and cut the hair, as hereinafter more particularly explained.

Figure 1 is a perspective view of my hairclipper, parts of the casing being broken away to show the position of the operating parts. Fig. 2 is a longitudinal vertical section through Fig. 1, showing the construction of the means for operating the knife. Fig. 2 is a plan view of the operated portion of the reciprocating arm, showing cam for operating same and slots in said arm. Fig. 3 is a longitudinal sectionthrough the hair-clipper, showing an alternative form of means for operating the knife.

In the drawings like characters of reference indicate corresponding parts in each figure.

On reference to the drawings it will be seen that I employ the ordinary cutter-bar,knife, and their connected parts, with a few modifications, in carrying out my invention.

The casing A is held together by suitable studs a, provided with 'nuts screwed on to their upper ends and being riveted to the casing at their lower ends. The bottom plate B of the casing projects some distance in front of the said casing at B and has secured to its under side by the screw 0 the cutterbar 0.

in the slot e of the knife F. The retaining cap E is provided with a lug 6 which, extendin through the slot e in the knife F,'fits a slot e in the cutter-bar C. I This is the same construction as is in the hair-clippers now commonly in use.

G is the adj usting-nut of the threaded stud D, which rests upon the washer H.

The back portion of the knife F abuts the forward end of the plate B, as shown at B Secured to the stud I, which has bearing in the casing A, is a spring J, which rests upon the drive-Wheel K, having bearing on said stud. Secured to the under side of the drive-wheel K is a pawl j, which is held by the spring is (which is also secured to the under side of the drive 1 wheel K) in contact with the ratchet-wheel L, which is keyed to the stud. This construction is the same as is used in an ordinary clock and operates the same way.

'M is the head of the stud I.

Meshing with the drive-wheel K is a driven wheel N, keyed to the stud O,which has bearing in the casing A. Meshing with the driven wheel N is a pinion P, keyed to the stud Q, which has bearing in the casing A.

R is a reciprocating arm secured to the bottom plate B by the pivot r. This reciprocating arm extends through the slot S in the front Tof the casing A and by means of the depending piece U extends into the slot e in the knife F. Where the studsD, I, and 0 pass through the reciprocating arm R are slots 2, 3, and 4. (See Figs. 1 and 2*.) These slots permit the movement of the reciprocating arm around its pivot r.

5 is a slot in the rear end of the reciprocat in g arm R, in which operates the cam 6, which is keyed to the stud Q.

Secured at 9 to the forward end of the le ver 8 (which is pivoted to the bottom plate B by the pivot 7) is a compressing lever 10, which passes through the hole 11 in the side of the casing A. The upper and rearwardly extending portion 12 of the lever 8 is connected by the spring 13 to the stud 14.

4 15 is a dog pivoted at 16 to the top of the lugs 26 and 27) is a plate- 28.

rights 25 and between the plate 2 8 and the ter-bar O is a guard 23, which is provided with teeth 24, which hold the hair in position while it is being cut by the knife F. Held in position under the guard 23 and secured to the uprights 25 (which have bearing in the On the uplugs 26 are springs 29.

30indicate cross-pins which prevent the uprights 25 from moving out of their bearings.

The object of the spring-controlled late 28 is to enable the operator to maintain; the guard 23 the desired distance fromthehead, so as to out the hair tothe desired length, aswill be understood.

S is a depending piece secured to the re- I taining-capE and extends down on. each side of the reciprocating arm B, so as to form a side support for said arm to prevent it; from moving too far either way. The said recip rocatingarmof coursepasses underneath the depending piece S through thQS10t1S- i Having now described the principal parts involved in my inventiomljshall. now. de; scribe its operation.

Before the clipper can be operated the spring of course must be woundup. This-is done in the usual manner. Tostart the clipper in operation, the comprsSSiDg-leverlgO-is 7, and by means of the pin-17; operating i nthe slot 18 move the dog- 15 around.itspivot ldin the direction indicated byarrow, thus; permitting'the end 270 of the arm Rt -escape the square shoulder 21 and revolvein thedirection indicated by arrow; As; the spring unwinds the energy therein, iscommnnicated from the drive-wheel K to the pinion" I?" by means of the driven wheel N, as will understood. This movement having revolved the arm 19 and the: stud Q revolves-12119- cam; 6, which abuts the sides of the sloth, giving a reciprocating movement to the; arm It}, which by means of its dependingrpiece U. resting in the slot 6 communicates motion to the knife F and severs the hair, aswilLbe:

understood. When the compressing-lever 10 is released, the spring; 13: draws the lever 8 back into the position shown in Fig. L,.so that at one point of its revolution its. end 20 comes in contact with the fixed shoulder 2L',, as shown. This, it will be seen, stops thecli-p-v perfrom operating, The compressing-lever 10 can of course be operated to produce-theabove operation as often as desired, or the said compressing-lever can be held by the thumbinwardly and operate its connected parts as before described, thus permitting the arm,19

to be revolved continuously. and thllskeepthe clipper working continuously;

native form of mechanism for operating the hair-clipper. The back part of the casing A is provided with a bearing 26, in which has bearing the stud Q. Secured to or forming part of the stud Q is a collar 27, which abuts 28 is a cap screwingover the bearing 26 and inclosing the collar 27. The collar 27, it will be understood,

The stud Q extends through the cap 28 out a short distance, so that any suitable means for driving-the said stud and its connected parts for operating the reciprocating arm R may be securedthereto.

In the drawings I have indicated that a 3 suitable sleeve or universal joint 29 (such as is used in connection with dental engines) might. besec-uredto. the stud Q by a set-screw 30; or any other suitable means and be driven from; any suitable source.
