To all whom it may concern:

Be it known that I, HUGH DRYSDALE, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful Animal-Clippin g Machine, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 is a vertical longitudinal side view of the entire machine.

, Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to that class of animalclipping machines which are designed to be operated by the hand or by power; and it consists in a novel construction and arrangement of the parts, as is hereinafter more fully set forth and claimed, by which a more effective device of this character is produced than is now in ordinary use, and the nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the stand or body, B B 15 its legs, 0 a rotary frame secured on the top of stand, and F a balancebeam sustained in said stand and supporting the droparm I, constituting the framework of the machine. The beam F carries on its rear end a counterbalance L, that is rendered adj ustable thereon by means of the set-screw L. 011 the forward end of same is permanently secured an L-shaped lug G, the lower portion of which is hinged to and between the bifurcated drop-arm I by means of the shaft II passing through the extensions 6 e of said arm and said lug that said arm may be swung to or from the body of the machine, as referred to hereinafter. Said beam F is secured in a bearing provided in the arm extension D of the shaft X by means of a set-screw, as shown in Fig. 4:, the threaded portion of which enters a transverse slot or groove in the beam that prevents end motion of said beam in said arm and permits of a rotary motion of said beam in said arm to the extent of the slot or groove in said beam, that the drop-arm I aforementioned may be swung to the right or the left of the perpendicular thereof, and at the same time be tilted up or down on the shaft X in conjunction with the t0and-from swinging motion aforedescribed, thus giving to the drop-arm a great range of motion. WVithin the hollow of said drop-arm I is provided a shaft 01, (see Fig. 3,) with suitable bearings on the boss 0 and in the socket-piece y, and is secured in place by means of the bevelgear a pinned to upper end of shaft and resting on said boss. A slotted socket-piece is pinned to the lower end of same, that shoulders within the socket-piece y, that prevents end play of said shaft in saidvarm, and referred to hereinafter. The socket-piece y is recessed to correspond with the shouldered end of the L-shaped lug J, and these parts are secured together swivel-like by means of the screws 6 c, or their equivalent, extending from the sides of said socket-piece under said shoulder in such a manner that said lug may be readily rotated therein and by said means is said lug J coupled to or uncoupled from the drop-arm I and swivels with respect thereto.

The L-shaped lugs J and P are provided with gear-pits f and f. Their corresponding extensions are journaled, male and female, as shown in Fig. 5, and are secured together by means of the shaft g',extending through them, with bevel-gears a and a pinned on either end thereof within said pits, which prevents said lugs from separating, but permits them to revolve one over the other. Said lug J is provided with a shaft g, that carries on its lower end a bevel-gear a, that meshes into and drives the gear a The upper end of said shaft extends out of the lug and is provided with a washer h, secured with a pin that prevents end play of said shaft in said lug. The outward-extending portion of said shaft 9 carries a drive-pin that corresponds to the recessed and slotted socket-piece Z, carried on the shaft d aforementioned, engages therein, and is driven thereby. Thus it is obvious that the shafts d and g are coupled to or uncoupled from each other simultaneously with the coupling or uncoupling of the lug J to the drop-arm I aforedescribed. A shank-piece y is formed with a journal y and a transverse vertical back an and is secured to the L- shaped lug P by means of the shaft 9 extending through them, with a bevel-gear a pinned on one end, that meshes into and is driven by the bevel-gear a On the opposite end is pinned the disk u, that shoulders within the axial bore of the vertical back m, that prevents end play of said shank, but permits rotary motion thereof. Thus it will be seen that the shank 1 is rotated on the shaft g, revolved on the lug P and swiveled on the lug J in the socket y with respect to the drop-arm I. A tubular handle 713 (shown in lateral section in Fig. 10) is secured to a shoulder extension g on the vertical back m by a driving fit, and by which the cutting parts are directed on the animal in the hand of the operator. Extending forward from the lower edge of said vertical back m are two base-blocks n n, (see Figs. 6 and 11,) to the under side of which is secured by screws a comb-plate 5c of the usual construction, and from each end of said back or are two similar extending cars 01 a, one above the other,which are provided with pins 0 0, secured screw-like therein, that serve as a supporting-slideway for a drive-head z, referred to hereinafter.

The drive-head consists of a rectangularshaped block 2. A vertical View of the back of same is shown in Fig. 9 and a top plan view in Fig. 10, and has a downward extension 1:, transverse slideways corresponding to the slide-pins o 0 aforementioned, a round recess 2 vertically let therein from the top, with a mill cut or slot from the back into said recess, and carries a ball t and cap-piece F corresponding thereto, and referred to hereinafter. Said drive-head z is slidably mounted on said slide-pins independent of the vertical back on and cutter-plate s, but in suitable contact therewith, the downward extension '2) engaging with the notch s in the cutter-plate 8, (see Fig. 8,) and the ball 25 has an opening corresponding to the crank-pin and engages thereon, as shown in Fig. 11. Thus it is obvious that by rotating the disk to said head is reciprocated on said pins, and with it said cutter-plate on the comb-plate :23, by reason of their engagement, as above described.

I make use of the round recess 2 and the ball 25 therein, for connecting the crank-pin with the drive-head, as affording a most perfect connection of the crank-pin and head with the least possible friction. I separate the drive-head from the cutter-plates, as described, that all the knock and jar caused by the crank-pin in its circular path will be retained within said head and on said pins, so as not to interfere with the tensioning of the cutter-plates, referred to hereinafter.

The cutter-plate s, reciprocated on the comb-plate 00, as above described, is guided in its lateral reciprocation by means of the two guide-pins 1 extending downward from under side of presser-plate (1 (see Fig. 7), and extend through rectangular slots 5 s in the cutter-plate into corresponding openings in the co1nb-plate, the rear edge resting on the base-blocks 'n n, the forward edge resting on the forward edge of the cutterplate 8, and secured to the comb-plate as by means of the binding-screw w and thumbnut 29. Said screw is introduced therein from under side of comb-plate a; and extends upward through suitable openings provided in all three plates 00, s, and q and part way through the thumb-nut p, it being threaded to correspond to said binding-screw. The manipulation up or down of said nut on said screw causes the presser-plate to clamp the cutter-plate s to the comb-plate w and create a tension of the cutter-plates more or less tight, as the tension desired to clip the hair may require. The tension thus required is maintained by means of the set-screw r, having a thread corresponding to that in said nut, and is entered from the top and forced against the end of said binding-screw, that cramps the thread of the nut in opposite directions, thus causing a frictional lock of the nut and binding-screw that is of sufficient strength to hold any desired tension from changing by reason of jostling or hard usage and is of such a nature as to be quickly and easily reset to any desired tension. I secure and tension the cutter-plates, as above described, independent of the drive-head z, in order to avoid in said knives the knock and jar that is common in said head, to leave the cutter-plate sfree to move on the comb-plate sensitively subject to its tension.

' The shaft H aforementioned, besides hinging the drop-arm I to the beam F, carries on one side of the lug G a bevel-gear a, that meshes into and drives the bevel-gear a, and the continuous shafts cl, g, g, and g and their respective trains of bevel-gears, together with the disk a, drive-head z, and cutter-plate 5. On the opposite portion of said shaft H is carried the band-wheel b, that is connected by means of the belt Q to the fly-wheel R, carried on the shaft E in the frame (I. The revolvin g of said wheel R imparts motion to the band-wheel I), shaft 11, gear a, and the continuous line of incased shafts, drive-head, and cutter-plate aforedescribed. The shaft E also carries a pinion S, that is geared into and is driven by the geanwheel T, carried on the shaft IV. Said shaft may be driven by a handle O or bya belt from a power passing around the pulley N. The legs of the machine are threaded into the downward extensions of the plate A. Upright columns U support a table-plate A, upon which is secured a corresponding base-plate V of the frame 0 by means of the base-bolt M, that permits the stand 0 to rotate upon the body A in conjunction with the up-and-down rocking of the balance-beam F, and the to-and-from and the lateral swing of the drop-arm I aforcdescribed.

The drop-arm I is calculated to furnish bearings for the shafts and their gears and to carry the clipping device independent of said shafts in such a manner that they are properly united, but free from the weight thereof or the friction caused from cramp or twist in operating the drop-arm and clipping parts over the animal. Said drop-arm also serves to shield the operator and prevent foreign substance from wrapping on said shafts when in motion.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is-- 1. In an animal-clipping machine, the cut ter-carrier consisting of a shank-piece y, terminatin g in a back m, and formed with projecting base-blocks n n, similar extending ears n n, in combination with a comb-plate 0a, a cutter, means for operating the same, slidepins 0 0, and a handle-case 70, substantially as set forth.

2. In an animal-clipping machine, the cutter-carrier consisting of a shank-pieccz vertical back m, formed with base-blocks n at, similar extending ears n n, slide-pins 0 o,

comb-plate x, and handle-case 7c, in combi- 5o 4. In an animal-clipping machine the drop- 7 arm I consisting of a tubular extension Z, and formed with a socket-piece y, swiveling with respect to the swivel-arm, one end bifurcated and hinging with respect to the balance-beam F, in combination with a shaft d, incased and supported in bearings within said arm independent of the swivel-arm and rotating handle, substantially as set forth.

5. The combination in an animal-clipping machine, of a drop-arm I, incasing and sup porting a shaft d, and having a socket-piece y, and means of engagement 6 e, with a swivelarm .I, and shaft independent of the shaft cl.

6. The combination in an animal-clipping machine, of a shaft d, supported and incased within a drop-arm I, and having a slotted socket-piece Z, with a swivel-arm J, having a shaft 9, and a coupling-pin 2', engaging with said slotted socket-piece, substantially as set forth and for the purpose specified.

'7. In an animal-c1ipping machine, the rotating frame consisting of a base-plate V, formed with standards 0, and having bosses and bearings therein suitable for the shafts W E and X, in combination with the shaft W, carrying a band-wheel N, gear-wheel T, a shaft E, carrying a pinion S, and grooved wheel R, a shaft X, formed with an arm extension D supporting the balance-beam F, in a rotary and tilting manner, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this 25th day of May, 1891.

HUGH DRYSDALE.
