,The invention relates to improvements in rotary clippers,

The object of the present invention is to improve the construction of rotary clippers, and to provide a simple, eiiicient'and come paratively inexpensive device of this character, designed particularly for clipping beards, and capable of ready adjustment to take up wear of the cutting edges and maintain the same in proper coperative relation.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacriiicino' any of the advantages of the invention.

n the drawing Figure 1 is a plan view of a rotary clipper, constructed in accordance with this invention. Fig. 2 is a Vertical sectional view, taken longitudinally of the rotary cutter; Fig. 3 is a horizontal sectional view with the rotary cutter removed. Fig. 4 is a central vertical sectional view, taken at right angles to Fig. 2. Fig. 5 is a sectional view on the line 5-5 of Fig. 2.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing in which is illustrated the preferred embodiment oi the invention, the clipper comprises in its construction a rotary cutter l, mounted within a frame or casing 2 and coperating with a relatively fixed blade 3 adapted to be adjusted to take up or compensate for the wear and maintain the parts ractically in the same relative position. he frame or casing is composed of spaced sides 4 and 5 and a connecting portion 6 curved concentric Y with the rotary cutter and arranged spaced relation'with the same, and located at the front of the clipper. The curved connecting portion 6 is provided at its lower portion with curved depending teeth 7 al.'L ranged at intervals and forming a guard.

The rotary cutter, which consists of spirally arranged blades, is preferably mounted on a shaft 8 and is detachably secured to the Same by a set screw 9, or other suitable means. The rotary cutter is of a length to extend across the space between the sides 4 and 5 of the frame or casing, and the latter is provided in its sides with threaded openings 10 and 11 into which are screwed threaded tubular bearings 12 and. 13 for the reception of the said shaft 8. The bearing 13 is provided at its outer end with an annular'flange 14, which fits against the outerl face of the side 5 of the frame or casing, and

the other bearing 12'is provided at its outer portion with an integral gear case 15 tting against the oute'r` face of the side 4 of the frame or casing and receiving beveled gears 16 and 17 mounted, respectively, on the shaft 8 and on a vshaft 18. The gear case houses the gearing and eectually prevents the same from coming in contact with the beard or other object operated on. The shaft 8 is extended at one end into the gear case, andy the gear 16 is secured to the shaft 8 by means of a pin or key 19. The gear case is provided at the front and back with o en ings 2G of a size to permit the pin 19 to e readily driven into or outo alined perforations of the gear 16 and the shaft 8.

ylhe gear 17, which meshes with the gear 16, is secured to the shaft 18 by a key or pill 21, and the shaft 18, which extends through a handle 22, is designed to be connected by a flexible shaft not shown) with any suitable engine or motor Jfor actuating the rotary cutter. rlhe handle 22, which is arran ed at an angle to the frame or casing, ias a threaded inner or lower portion 23, which screws into an interiorly threaded tubular portion 24 of the gear case. The gear case may be provided with a threaded opening 25 normally closed by a threaded disk 26 and adapted to facilitate the iinishing .of the interior of the gear case. After the gear case has been finished, the closure disk or plate may be secured in the opening by the screw threads, or any other suitable means.

The relatively xed blade 3, which extends upwardly and rearwardly from the bottom of the frame or casing, is pivoted between the sides thereof at the rear terminals of the same. The relatively fixed blade is provided at its upper portion with integral projecting pivots 27, and the sides 4 and 5, which have bearing openings 28 to receive the pivots 27, may be sprung apart to permit the pivots 27 to be introduced into the openings 28. The relatively fixed blade is adjusted by means of a screw 29, having a milled head 30 and mounted in a threaded I,opening 3l in the upper end of an arm 32, formed integral with the `blade 3 and extending upwardly and forwardly from the center of the top port-ion thereof to the front of the frame or casing, as clearly illustrated in Fig. 4 of the drawing. The arm 32, which is provided at its inner face with an arcuate recess 33 to clear the rotary cutter, is adapted to be forced upwardly against the action of a pair of springs 34 to move the cutting edge 35 of the relatively xed blade 3 toward the rotary cutter. The spiral cutting edges f of the rotary cutter move over the cutting edge 35L with a shearing action, and the springs 34, which are riveted or otherwise secured at their rear ends 36 to the inner or upper face of the blade 3, are located adjacent to the inner faces of the sides 4 and 5 of the frame or casing, and have their front ends bearing against the undersides of pins or studs 37, projecting from the inner faces of the said sides of the frame or casing. The springs 34 urge the pivoted blade 3 downwardly away from the rotary cutter, and the screw positively forces the cutting edge of the pivoted blade inwardly toward the rotary cutter. Thepivot-al adjustment of the blade 3 enables the cutting edge thereof to be maintained constantly in practically the same relation with the cutting edges of the rotary cutter. The pivoted blade is provided with an oblong opening 38, and the frame or casing -is open at the top so' thatV a clear view of the rotary cutter and the cutting edge of the pivoted blade is afforded at all times. The gear case is provided.

at the top with an oil hole 39 for lubricating the gearing.

What is claimed is 1. A rotary clipper including a frame or casing having spaced sides, a rotary cutter arranged within the frame or casing between the'spaced sides thereof, a relatively fixed blade pivoted between the sides of the frame or casing and extending beneath the rotary cutter and provided with an'arm arranged atan angle to the pivoted blade extending forwardly over the topof the rononame.

tary cutter, and a screw mounted on the arm and coacting with the frame or casing for moving the blade.

2. A rotary clipper including a frame or casing having spaced sides, a rotary cutter arranged within the frame or casing between the spaced sides thereof, a relatively fixed blade pivoted between the sides of the frame or casing and extending downwardly and forwardly beneath the rotary cutter and provided wit-h an arm arranged at an acute angle to the pivoted blade and extending forwardly over the top of the rotary cutter to the frontl of the frame, a screw mounted on the arm and coacting with the frame or casing for moving the blade, and springs located at opposite sides of the frame or casing and arranged to urge the same away from the rotary cutter.
