Toall whom it may concern;

Be it known that ll, EDWIN HERBERT DAY, a subject of the King of Great Britain and llreland, &c., residing at Bendigo, in the State of Victoria, Commonwealth of Anstralia, have invented certain newy and useful llmprovements in Clipping or Shearing Apparatus; and 1 do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will e nable others skilled in the art to which it appertains to make and use the same.

rlhis invention relates to durable clipping or shearing apparatus having a duplex reciprocating cutting device on a handpiece to be held to its work by one hand, as the right. This part, herein called the cutting tool, is provided with a non-rotating flexible member (as a wire of convenient length) connecting it to a means of supplying power for the cutting tool consisting of a second tool which is to be held and operated by the other hand of the worker. This power device will be called the drive tool or the left hand piece though it can be worked by either hand, and the cutting tool may be called the right handpiece, though'it might be used -in the left. Fach tool can be moved independently of the other, within the length of the connection. 'lhe flexible wire allows the cutting tool to be easily moved about, and as the hand holding the latter has only to locate it accurately, it is more able to do so than if the same hand had also the labor of producing the reciprocating action.

'llhe construction has time saving features and has no parts which rotate during clipping, and it is simple, and more convenient in some respects than ordinary clippers. A barbers clipper does not allow of a person cutting his own hair, but ll can out my hair well and easily with my apparatus, though l have had no previous practice. lts use is not restricted to human hair cutting.

Referring to the drawings herewith, which form part of this specication, Fig- -ure l represents a partly sectional vievT of my apparatus ready for use, with part of the flexible connection omitted, the cutting tool being in plan. Fig. 2 shows, partly' in section, parts in Fig. 1 with the drive tool .handles pressed together, and the cutting tool in side view, with itscutter retracted. Fig. 3 illustrates the handle and comb of the cutting tool, in plan. Fig. 4 shows a side elevation in vertical section of the cutting tool head. Fig. 5 shows al plan of the cutting tool with its parts in normal positions. Fig.' 6 repeats Fig. 5, but with the cutter retracted, and part of a tension spring omitted to show the comb end. Fig. 7 shows the cutting tool head in transverse vertical section, and Fig. 8 shows, in plan View, part of the under side of the said head. Figs. 1 to 3 are on a smaller scale than the other views.

Designs, Vrelative sizes, numbers, and minor details of various parts, may -vary from what is illustrated while remaining Within the scope of my claims.- Y

*' lhe drivey tool has handle'sides Y1, 2, normally wide apart, and pivoted as at 3, but after being pressed near one another and released they resume their normal positions. The said pressure pulls a flexible wire 7, 7 a, through a flexible casing 5, 5, 5b, made of any suitable material such as spirally wound wire, the wire at 7 being connected as at 4 to a handle 2, part 5u of the casing being fiXedor pinched in the handle 1 by means of screws 6, or the like suitable means. Any other drive tool however maybe used with the cutting tool, so long as its action is to pull a flexible non-rotating connection. rllhus a power (instead of a manual) drive is feasible, as for animal clipping and shearing. The drawing omits to show the said casing at part 7a of the wire. When a pull d raws the Wire longitudinally in the directlon of the arrow in Fig. 1, it causes retraction of the cutter blade 18, to which the wire 1s connected by a rod 14 having at one end a suitable (as screw) connecting means 17, and at the other end a cap 13 which may be set on the rod, and receive the end 5 of the wire. llod 14 on being retracted alters the tension of a spring device, asspiral spring 16 encircling the rod and located between an adjustable nut 15, which screws on rod 14, and a stop member 12 located in the cutting tool handle 9. The comb 23 is affixed to handle 9 (which can have any convenient shape) as by screws 9a. 'lhe respective toothed sides oit the cutter are marked 18a, 18"; and of the comb 23, 23h.

2l is a duplex hair length gage plate having toothed sides 24a, 2lb. rlhe comb alone will act as a gage when it is required to cut hair very short. lf plates with similar sides are used, a series of them would be provided and changed according to the lengths of hair wanted, as each gage can be attached or detached easily, as by slide or screw devices, or a combination thereof. When pressure on handles 1,-2, is withdrawmtbe spring 16 advances the nut 15 and thus rod 14 and cutter 18, to norma-l positions.

' 2O are studs or guide postswhich project from the comb into central lslots 19 which are'in a longitudinal line in the cutter and heads each to hold an adjustable nut 21 vby which to locate partfof a tension plate 22.

.A spring plate which'bears on the cutter is illustrated, middle pressure being suitable, but plates adapted for other locations of pressure are usable to produce the desired tension. l

An aperture 10 in handle 9 would allow of inspection'and'attention to a screw '9% but is mainly intended to allow vadjustment f ing a hole in the gage plate just large enough for it and put in by a turnscrew is a-simple `arrangement usable, to' fix securely in'pl'ace the said gage' late. The end of a handle as 1 is shown ormed with an edge adapted for 'inserting screw.

'Plate 241msome cases may b e made removable without using a tool.. Thus it.will be apertured or slotted at 27 and 27 for parts of it to pass holding members 27, 27?, which may be screws set 1n position to hold the gage irmly. Or, as in Fig 8, there is a slot 27 for engagement by screw 27, and a dovetailed arrangement of the comb and gage, as in Fig. 7. In Fig. 7 plate l24 has sides of' dissimilar thickness, side-24:EL being the thicker, the intermediate under surface havin any suitable form, a smooth slope 28 belng illustrated. The length of hair left after 'the cut can be regulated accordingly without altering the cutting tool.

Simultaneous double cutting can be avoided`.by' holding`the cutting tool appropriately, but v-it is at times more economical to make simultaneous or double cuts, and with practiceit is:feasible by pushing the 'one sided combs, cutters and gages.

or removing the said cutter with its more thickly .gaged side in front, in the direction of the arrow in Fig. 7. Ihuse a gage in some cases having teeth at only one sideof the comb, the under` side of the gage extending for example along the dotted line to point 30 Fig. 7, asv this would leave the comb-on the other side to act as a gage for very short cutting.

The 'gage has blades which (see Fig. 8) are as thin as desired, and extend -out beyond the comb` teeth with which they register The comb teeth extend as usual beyond the cutter teeth. The tops of the teeth of all the parts have an upw ardslope or the like, and those of the gage rise somewhat v higher than the comb teeth as at 31 in Fig.

7. This acts as a guide, to prevent hair or wool getting between the comb base and the gage top. r f

In my claims the word duplex means that the part so called has two sets of teeth orfis double sided, as distinguished from Parts areso smoothed or rounded as to avoid unpleasantuess to the subiect to be clipped.l
