UNITED STATES PATENT OFFICE OLE OLSEN, OF OAKLAND, ASSIGNOR OF ONE-HALF TO CHARLES GREENE,
' `OF SAN FRANCISCO, CALIFORNIA.
SPECIFICATION forming part of Letters Patent No. 511,966, dated January 2, 1894.
Application filed August Z5, 1893. Serial No. 484,038. (No model.)
To all whom if may concern:
Beit known that I, OLE OLsEN, a subject of the King of Sweden and Norway, residing in Oakland, Alameda county, State of California, have invented an Improvement in Hair-Clipping Machines; and I'hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to that class of hairclipping machines in which a reciprocating toothed plate works upon a fixed tooth plate.
My invention consists in the novel details of construction, arrangement and combination which I shall hereinafter fully describe and specifically claim.
The object of my invention is to provide a hair-clipping machine which, by reason of the hinge connection between its handle and head, may be adjusted to varying positions, thus adapting it for the most convenient operation under all circumstances and in different places.
Referring to the accompanying drawings for a more complete explanation of my invention,-Figure 1 is a perspective view of my hair clipping machine. Fig. 2 is a plan of the head portion, the handle sleeve being in section. Fig. 3 is a central longitudinal vertical section.
A is the main or fixed plate having the teeth a.
B is the reciprocating plate having the teeth b adapted to Work upon the teeth a in the usual manner.
From the rear edge of the main plate A rise brackets C, the forward ends of which fit in a groove h in the plate B whereby said plate is accurately guided in its movement. These brackets are formed with spring tops c regu` lated by screws c2 extending upwardly from the main plate, and in these brackets and their spring tops are formed bearings in which are pivoted the journals d of a yoke D which said yoke forms part of or is secured to the handle sleeve E.
In the journals d of the yoke is mounted a reciprocating shaft F which carries at its middle a collar f having in its back edge an elongated groove f, and in its forward edge a rib or flange f2, saidgroove and said flange being circumferential of the collar. The back of the collar is squared off to abut against the face of the yoke D, whereby the collar is turned with the yoke and handle sleeve. The/rib or vflange f2 fits down into and plays in the groove seat bzin the reciprocating or movable plate B.
Extending through the handle sleeve E is thel rotary shaft G having at its inner end an eccentrically located pin or crank stud g which fits in the groove f of the collarfof' shaft F. From the construction of the device as thus far described it will be seen that when the shaft G is rotated, it will, through its eccentric pin or crank stud g acting in the groove of the collar f, cause the shaft F to move back 'and forth in the direction of its length, said shaft playing through the journals d of the yoke D. This movement of the collar, acting through its rib or flange f2 which engages the plate B, will canse the reciprocation of said plate. Itwill be seen also from this construction that the connection between the handle portion of the machine and what may be termed the head portion, and which consists of the two-toothed plates, with their brackets, is a hinged one, adapting the two portions to be turned to various positions with relation to each other. Thus, for example, the tooth plates may be turned to a plane below and parallel with the line of direction of the handle, with their. teeth extending forwardly; and again the plates may be turned at right angles to the line of handle, or by a further movement the plates may be turned to aplane above the handle and parallel with its direction, the teeth extending backwardly, and it is obvious that positions between these limits may be reached. These adjustments enable the machine to be used conveniently in any position and to be operated in various heretofore inaccessible places, or in places accessible only bythe most inconvenient positions of the operator. It will also be seen that by reason of the construction of the power-transmitting connections described, these latter remain in engagement in whatever position the two parts of the machine may be turned.
The means for operating the shaft Cr are as follows: The end of the shaft G carries a bevel pinion g with which engages a bevel gear H which is connected with a winding arbor I by the usual pawl and ratchet connection represented by z', said arbor having a power spring J. These parts are all contained within a box K which is secured to the end of the sleeve E by means of a nut L -screwed into the sleeve and secured to the box, said nut also acting as a stop against the reduced end of the shaft G whereby the pinion of said shaft is held to its engagement with the main gear.
Upon the handle sleeve is an ordinary handle M, over the inner end of which is adapted to ita slidable ferrule or ring N, to which is attached a rod n extending backwardly and adapted to enter and to be withdrawn from a hole in the pinion g. Upon winding the spring arbor, its energy may be preserved by moving the ferrule or ring in one direction whereby the rod n'will enter the hole of the pinion g and prevent the parts from turning.
When it is desired to use the machine, the ferrule or ring is slipped in the other direction thereby withdrawing the rod from the pinion and freeing the parts.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A hair clipping machine, having its headportion which carries the toothed plates loosely suspended from the handle portion and capable of swinging about its point of suspension to enableits position to be changed from a horizontal position parallel with and below the handle with the teeth extending forwardly, to a position parallel with and above the plane of the handle with its teeth extending rearwardly.
2. In a hair-clipping machine, the combination of the head portion consisting of the fixed and the movable toothed plates,a handle portion, a slidable shaft connected with the movable 'plate and forming a hinge connection between the head and handle portions, whereby the two may`be turned i'nto various positions with relation to each other, and power transmitting mechanism comprising a rotatable shaft havin g, an eccentric connection with the slidable shaft for operating the movable plate, adapted to remain in engagement in whatever position the head and handle portions may be placed, substantially as herein described.
3. In a hair-clipping machine, the combination of a xed toothed plate, a reciprocating toothed plate operating thereon, ahandle hinged to the fixed plate upon an axis that is parallel with the plane of the toothed plates whereby it may be turned to various positions with relation to the toothed plates, a rotatable shaft and an eccentric connection between said shaft and the reciprocatingl plate whereby the latter is operated, substantially as herein described.
4. In a hair-clipping machine, the combination of the fixed and the reciprocating toothed plates, the handle sleeve having journals pivotally seated in bearings on the fixed plate, the slidable shaft mounted in said journals and having the collar with a rib or flange engaging a groove in the reciprocating toothed plate, and the rotatable shaft with its eccentric or crank pin engaging a groove in the collar, substantially as herein described.
5. In a hair-clipping machine, the combination of the xed and reciprocating toothed plates; the handle sleeve having a yoke with journals pivotally seated in bearings on the fixed plate, the slidable shaft mounted in said journals and having a collar abutting upon the yoke, said collar having on its front a iiange or rib engaging a groove on the reciprocating plate, and in its back a groove, and the rotatable shaft in the handle sleeve having an eccentric or crank pin engaging the groove in the back of the collar, substantially as herein described.
6. In a hair-clipping machine, the combination of the fixed and reciprocating toothed plates, the handle sleeve pivoted thereto, a
rota-tableshaft in the sleeve and connections between said shaft and the reciprocating plate for operati ng the latter, the spring driven gear at the end of the handle sleeve, and a pinion on the rotatable shaft engaging said gear, substantially as herein described.
7. In a hair-clipping machine, the combination of the fixed and reciprocating toothed plates, the handle sleeve pivoted thereto, a
rotatable shaft'in the sleeve and connections between said shaft and the reciprocating plate for operating the latter, the spring driven gear at the end of the handle sleeve, a pinion on the rotatable shaft engaging said gear, the sliding ferrule or ring and the rod thereof engaging and relieving the pinion for throwing the power mechanism into and out of action, substantially as herein described.
8. In a hair-clipping machine, the combination of the power transmitting shaft, the handle sleeve through which it passes, the box or casing having the nut screwed into the handle sleeve and embracing a reduced end of the power shaft and spring actuated gear ing within the box or casing for transmitting power to the shaft, substantially as herein described.
In witness whereof I have hereunto set my hand.
