. Figure 14 isa front edge elevation of the plate shown in Figure 12.
Figure 15 is a view of the modification tutes a casing for the actuating niechanismtherefor. In the construction shown in Figures 1 to 5the casing constituting thebody has at the forward` end portion thereof a web, 20, which supports a terminal element of the actuating mechanism seen at 21'engagingthe vibrating cutter, 23, located immediately infront of said web, 21, Awhose .for-
ward edge serves as the guide for the vibrating movement of the cutter,22,. which is pron vided with upstanding lugs, 24, for engagement ofy the actuator,'21. Mounted rigidly upon the under side ofthe web', 20, there'isprovided a plate, 25, extending transversely withrespect to the advancingmovementofthe tool in hair cutting,-that is parallel with the vibratory movement of the vibrating cutter,-
for supporting in a manner hereinafterdescribed a combined comb and cutter blade v member, 30, upon whose upper face forward of the forward edge of said web, 20, the -vibrating cutter, 23,is lodged, the two parts co-operating for severing the hair in the reciprocation of ythe vibratory'7 cutter relatively to said combined 'cutter and comb, said combined member is engaged and carried in position for lodgment upon it and in co-- loperation with it ofthe vibrating cutter, 23,
by a tongue-and-groove engagement between ,said combined member, 30, and the plate, 25,
the latter being foimed withl down turned flanges at its opposite end between which the member, 30, is embraced', said flanges having tongues, 31, 31, andthe end edges of the combined member, 30, having grooves, 33, 33, which engage said tongues whereby the member, 30, is `mounted for slidin fore-and-aft with res ect to the body, A, of the tool, and also wit respect to the vibratory cutter, 23,
which has only the transverse vibratory movement, and which is xed as to its foreand-aft position. The comb teeth of the member, 3.0,which are also cutter teeth, are
relatively longer than the teeth of the Vibrating cutter, 23, and the parts are arranged for range of sliding movement of the member, 30, with respect to the member, 23, substantially equal to the excess of the length of the comb-and-cutter teeth of the combined member, 30, over that of the cutter teeth of the Vibrating cutter, 23; so that at the limit of the forward movement of the member, 30, the teeth of the two members co-operate perfectly for admitting the hair to be entered to the' full depth of the teeth, and for severing the hair at'that point; and at a retracted position of the member, 30, the teeth of the two members, still co-operate for cutting the hair admitted .to the full depth of the teeth of the vibrating cutter. The bar, 25, is provided at the middle point of itslength with a downwardly projecting lug, 36, and the combined cutter and comb member, 30, has a longitudinal slot, 37, through which said lug, 36, projects and in which there is lodged a coil spring, 40, positioned between the lug, 36, and the rear end of the slot, and when the 'spring is extended the member, 30, is retracted to the limit at which theelongated teethof said member stand projecting to a minimum extent beyond the teeth of the vibrating cutter, 23; so that when the combined cutter and comb member, 30, is engaged slidingly with thevbar, 25, the member, 30, is ,held yieldingly thusv retracted to the limit indicated; andthe slot terminates at its forward end suitably for stopping the member, 30, at that position by encounter of the forward end of the slot with the lug, 36, M
The member, 30, which at its `upper face at the forward part co-operates with the vibrating cutter, 23, for cutting is tapered in thickness increasing rearwardly from the forward points ofthe comb teeth as indicated at 39 nearly to the rear end of said member, 30, and in any event past the lineof'cut, being preferably convexly curved as to its lower surface as seen in Figure 1, and being rounded up at the rear endor heel beyond the point of maximum-'thickness orlimit of taper. For
operating the member, 30, to thrust it forwardly subject to retraction by the spring, 40, there is provided a flexible connector indicated in totality by the letter B, which extends from the rear end of the combined 4cutter and comb member, 30, rearwardly under the handhold portion, A1, of the body, A, to the rear end of the body, said connector being normally flexed away from the under side of the body opposite the handhold portion, andbeingheld thus flexed by the reaction of the spring, 40, on the comb and cutter member, 30, to which at its 'forward end said connector is pivotally attached as seen at 45. In thel form shown in Figures l to 5 this connector is a fiat sprin bar which by reason of its elastic iexibility o tains substantially pivotal connection at its rear .end
to the casing although secured rigidly by screw, L46.
If preferred for any reason this flexible connector instead of being. a spring bar may be a jointed member as in the form shown in Figures 8 and 9; and we do not limit ourselves to the particular form shown in Figure 1, though for certain reasons this may b e regarded as a preferred form of this connector.
Upon considering the construction as thus far described, it may be understood that the barber grasping the tool by the handhold portion A1 of the body will at the same ytime have the connector, B, in the grasp of his fingers at the under side of the handhold and that as the tool is advanced'over the head of the customer, the combined cutter and comb member, 30, being at its normal retracted position, the barber may hold the tool with the points of the comb teeth in touch with the surface of the skin and thereby will effect the clipping of the hair so as to leave a stubble only of the minimum length equal to the thickness-of the comb. teeth at a very short distance rearward fromvtheir points at which the line of cut is located, that line being very near the points ofthe teeth of the vibrating cutter when the tool is ofthe power operated type in which the rate of vibration is so rapid that the hairs are severed almost instantly upon entering the teeth and without delay for them to reach the bottom of the recesses between the teeth.
It will be seen that if it is desired, to raduate the cut the barber may obtain this result while still holding the tool with the points of the comb teeth in touch wit the skin, by merely exerting pressure withf is lingers on the flexible connector, B, without materially altering his grasp upon the'tool for guiding it, the straightening of the'normally flexed connector which is caused by such pressure operating to thrust the cutter and comb member, 30, forwardly along the line of its sliding engagement with the body maintaining it in perfect co-operat-ing relation with the vibrating r:utter, but increasing the distance between the plane of cut and the skin by reason of the tapered thickness of the combined comb and cutter. y
And it will be seen that this graduation can be effected to the limit of the increase of thickness ofthe tapered `portion of the part, 30, from the forward points of the combteeth backY to the position on the comb teeth at which the line ofcut becomes located when roo the member, 30, is thrust forward to the limit I of the thrust movement which can be effected modification to described consists in substituting for the flat spring bar as connector,
a jointed member of which each part is or may be non-resilient in itself, the two parts indicated at and 51, respectively being pivoted together as seen at 52 at a point opposite the handhold portion of the body, the part, 50, being pivotally connected at its forward end ,to the member, 30, as in the earlier figures, and the part, 51, being pivotally connected at its rear end to the body toward the rear end.
The second modification referred to consists in applying the feature of a comb tapered in thickness and longitudinally adjustable, to a hair clipper of not uncommon type in which the fixed or non-vibrating cutter is distinct from the comb, or at least in which there is provided acomb member not integralwith and in that sense distinct from--the non-vibrating cutter blade. In Figures 8, `9 and 15' the non-vibrating cutter blade is seen at mounted'on a forwardly projecting lug of the l plate, 61, which corresponds to the plate, 25,
Yof the earlier figures.
v'And the comb member, 62; is slidingly mounted by tongue-and-groove engagement with the plate, 61, 'in the same manner as in which the earlier figures, the member, 80, is engaged with the plate',-25. AThe spring, 65, in these figures corresponds to the spring, 40, in the'earlier figures, and -is similarly accommodatedin a slot, 67, in the sliding comb member, 62, whereinl it is stopped at ,the forward end by a lug,"66, projecting from the plate, 61, corresponding tothe lug, 36, ofthe earlier figures. f y
Upon considering this construction it will be seen that it will operate in the same manner as the form shown in the earlier figures in respect to graduating thelength of the stubble by the pressure of the barbers fingers on the jointed iexible connector.
