HAlR CLilPPlNG MACHINE SPECIFICATION forming part of Letters Patent No. 330,535, dated November 1'7, 1885,

Application filed March 20, 1885. Serial No. 159,604. (Modem To all whom it may concern:

Be it known that we, OULLEN K. WHITTIER and JOHN H. DoNLoN, of the city and county of San Francisco, State of California, have invented an Improvement in Hair-Clipping Machines; and we hereby declare the following to be a full, clear, and exact description of the same.

Our invention'relates to a new and useful improvement in the class of hair-clipping machines ,and our invention consists in a curved plate secured to or formed with the under side of the comb-plate and acting as a bearing on which the head of the machine is adapted to rock.

The object of our invention is to enable the operator to graduate the length of the out, not by a fixed gage requiring a stoppage of the operation to adjust the gage, but by a rocking bearing which permits a graduation of the length of the out during the operation, while the machine is continuing its work, and on any portion of the hairsurface.

Referring to the accompanying drawing,

the figure is a perspective view of a hair-- clipping machine seen from the under side, and showing our curved bearing-plate E.

We have herein illustrated a well-known form of hair-clipper to which our improvement is applied, though it may be used with any machine of this class. It will be necessary, therefore, to only indicate briefly the various portions of the machine.

A A are the handles, pivoted at a; B is the comb-plate; O is the cutter-plate, and D is the cap-plate, all arranged and adapted. to operate in a manner now well known. The under surface of the comb-plate is usually made fiat, and therefor the machine is adapted for only one length of cut. In some machines, however, a supplementary plate is placed under the comb-plate, which is so at tached by screws or bolts as to have an adjustment to or from the comb-plate, whereby it acts as a gage to define and limit different lengths of cuts; but these gage-plates are invariably fiat also, and their adjustment is of such a character that in order to change the length of cut the operation must be stopped and the gage adjusted. They are therefore useful only in cases where one customer desires one length of cut and another desires a different length, and. this length is of course preserved throughout the operation. Our invention contemplates the graduation of the length of out during the operation upon a single customer, thus making the necessary slopes at different portions where required. To do this we have a curved plate, E, on the under side of the comb-plate. The length of this plate and its curvature may be varied to define the limits of graduation as may be desired. Its forward edge is here shown as extending in an unbroken edge to the base of the teeth on the comb-plate, while its extreme rear extends but a short distance behind the rear edge of said plate. This, we consider, is about the length it should have to make it conform. to the rest of the machine. It may be formed integral with the combplate, and in machines to be made the bottom of the comb-plate might be made to have this shape, if desired, thus doing away with a separate plate; or it may be a supplementary plate, as here shown, in which case we slit its rear portion, bending the side sections upwardly to form legs 6, the ends of which are again bent backwardly to form feet 6, through which small screws 6 pass into the comb-plate, whereby the plate E is firmly seated.

The operationis as follows: By separating the handles from the surface to be clipped as far as possible, the teeth of the comb-plate may be brought down closely against the hairsurface, and as short a cut as desired may be made. As the machine progresses and a gradually-lengthening out is to be made the handles are gradually brought closer to the hair-surface, the head of the machine rocking on the curved plate E, and removing its combplate and cutter-plate farther and farther from said surface, and thus increasing the length of cut. In this Way hair may be cut in styles which, on account of the lack of uniformity in the length over different portions of the surface, now require the use of ordinary shears.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. Ahair-clipping machine having a curved plate with unbroken front edge rigidly selegs 6 and feet 6, by which it is adapted to be secured to the comb plate, substantially as herein described.

In witness whereof we have hereunto set our 15 cured to the under surface of the comb-plate, said curved plate extending only to the base of the teeth on the comb-plate, and forming a bearing upon which the head of the machine rocks as the machine-is operated, substantially hands.
