MACHINE FOR `BRUSHING ANIMALS.

SPECIFICATION forming part qof Letters Patent No. 227,857, dated May 18, 1880i.

Application iled July 7, 1879.

To all whom` it may concern Be it known that I, NELsoN Srow, of Binghamton, in the county of Broome and State of New York, have invented certain new and in operation, and a flexible power-conveyer or flexible shaft to give said brush a rapid re-` volving motion, while enabling it to be freely moved about in various directions to operate at different points.

The object of the first part of my invention is to provide a power-driven brush for cleaning anim als, &c., which permits free escape of the dirt, dust, or loosened matter, while avoid-` ing all danger of entanglement of the animals tail, mane, or hair with the brush while in motion; to which end my invention consists n combining a skeleton-brush capable of a revolving motion with a non-rotatin g skeleton or` open guard or shield.

The object of thenext part of my invention is to readily stop or start the brush in operation without necessarily stopping the rotation of the iiexible power-conveyer; to which ends my invention consists in combining with the brush and hand-piece ofthe machine a clutch arrangement of the character particularly hereinafter described, whereby l am enabled `to start and stop the brush at will by coupling and nncouplingfit with the driving-shaft, so as to use the brush with the hand independently of its revolving motion derived from the driving-connections when desired.

My present invention also consists of certain other new combinations of devices,which are pointed out at the close of the specification.

In the accompanying drawings, which represent my improvements as embodied in the best way now known to me, Figure lis a front elevation of so much ofmy improved apparatus as is necessary to illustrate the subject-matter herein claimed. j Fig.v 2 is a side elevation thereof, partly in section, to show the clutch arrangement 5 and Fig. 3 is a longitudinal central section therethrough.

The hand-piece casing A is shown in the present example as composed of two tubular sections, a a', in the section c of which is mounted a journal or spindle, B, while the section a of said hand-piece constitutes a socket for the Vreception of one end of a flexible tube or sheath, C, which envelops and protects a iiexible power conveyer or shaft, D, such as is in common use, the said shaft being shown as composed of coiled wire with its layers wound in different directions. The inner ends of the sheath O and of the dexible "power-conveyer D are connected with a suitable prime mover, engine, or power, the sheath being' preferably incapable of rotating, while the shaft is given a rapid revolving motion, which is communicated to the journal or spindle B, to the butt-end of which the outer or `free end of the flexible shaft is connected in well-known ways.

The construction and organization of the llieXible power-conveyer, its enveloping-sheath,

and the driving power may be similar to that shown in reissued Letters Patent No. 8,607, granted March 4, 1879, to Samuel S. White, of Philadelphia,- Pennsylvania, as my assignee.

'The frontend of the journal or spindle B is socketed, as clearly shbwn in Fig. 3, and its said front end is provided with ashoulder or tooth, I), as shown in Fig. 2, with which acorresponding tooth or projection, c, on an endwise-movable chuck, E, engages when said chuck is moved inwardly to bring its tooth into contact with that of the journal B. The said chuck is provided with a tubular stem, E', which fits snugly in the socket of the journal B.

In order to govern the movements of the chuck E and bring it into and throw it out of actuating contact with the journal B, with.

IOO

I form the Working parts of the brush are selcircular rim or ring, J as clearly shown, pararms le, radiating from the screw-nut or hub h2,

turning by a longitudinal slot, a2, in said casing, into which a pin or screw, f, passing through au opening in the thimble, projects and engages with an annular groove, c', formed in the head of the chuck E, whereby said chuck may be moved endwise at will to connect it with or disconnect it from the spindle B by means of the pin or screw f, while its free rotation when connected with the spindle is unimpeded. n y

Inserted in the socket of rthe chuck E is the stem or shank of a shaft, G, which is rigidly fastened in the chuck, in this example, by a set-screw, d, passing through the head of the chuck E, the inner end of said screw bearing against a flattened or plane surface of the shank of the shaft, so as to lock it iirmly both as against endwise and turning movements independent of the chuck. (See Fig. 3.)

The shaft G is fitted to Aturn-freely in a bearing in a frame-piece or head, H, and is provided at its outer end with a bevel-pinion, g, meshing with a corresponding pinion, i, fixed upon a counter-shaft, I, fitted in bearings in said head H, so as to turn freely, when driven by the shaft G, at right angles to said shaft.

rIhe frame-piece or head His preferably constructed so as to incase the gear-wheels g 'e' and exclude dust and other extraneous matter therefrom. This frame-piece is composed, in the present example, of two pieces, cast with suitable bearings and in proper form, which are secured together, so as to constitute the inclosing-case, by three screw-nuts, h l1. h2.

The counter-shaft I, at one end, projects beyond the head H, and. has fixed thereto a hub, J, from which radiate arms j, connected by a ticularly vin Fig. 3, the said skeleton-frame so formed having the appearance somewhat of a wheel having a hub, spokes, and tire.

The bristles or other material which is to cured, preferably, in bunches along the face of the armsj and rim J', so as to constitute a skeleton-brush, the object of which is to aord free escape of the dust or loosened matter from and through the brush, so as to avoid clogging it.

A rapid revolving motion will be imparted tothe brush when its shaft I is driven, as will be obvious. Said brush may, of course, be made of different shapes from that shown. The circular or wheel like form, however, is preferred.

g lo avoid all danger of the brush catching the tail, mane, or hair of the animal being cleaned` while said brush is in motion, I provide a skeleton non-rotating shield or guard, K, which en.- velops or protects'the brush, while permitting free escape of clogging matter therefrom. This shield is composed, inv this example, of

the outer ends of the arms being bent down and connected together by a rim or ring, 7c.

It will be noticed that the head H and the shield or guard K, while not rotating with the brush and driving-connections, is still permitted to turn relatively to the hand-piece casing around the shaft G, in order to accommodate the guard to the surface over which the brush is working'. i g

rIhexoperation of the machine is as follows: Motion is imparted to the iiexible power-conveyer, and through it a rapid revolving motion is given to the journal or spindle B, which is communicated to the brush by its gearing, if the said journal and the chuck E are clutched together, the hand-piece A of the machine being grasped by the hand of the operator and moved about in various directions (or over the body of the animal being brushed) to hold the brush to its work. If it is desired to stop the rotation of theffbrush, the thimble on which the lingers of the hand holding the instrument may rest is moved outward, which uncouples the chuck from the revolving journal, and the rotation of the brush ceases without stopping the rotation of the flexible power-conveyer, and the brush may then be used as a non-rotating one. The brush is again started at will by a reverse movement of the thimble, or a movement inwardly, which couples the driving parts together. Y

It may be well to here state that in some instances I intend to dispense with the driving-gearing intermediate of the brush and the driven chuck of my machine and drive the brush directly by said chuck, the brush and chuck being connected together by any suitable connections.

I have described my improvements with reference more particularly to its animal-brushing capacity; but it will beobvious that my said improvements may be used for various other purposes to which they are applicable.

I do not wish to beL understood as claiming herein, broadly, the combination of an instrument with a clutch and iiexible shaft, whereby the instrument may be stopped or started at the will of the operator without interference with the driving power or rotation of the flexi- IOC) IIO

ble shaft, as sucha claim, thus broadly construed, would be invalid.

I claim as my inventionl. The combination, substantially as hereinbefore set forth, of the skeleton-brush with the skeleton guard or shield, whereby free escape of dust or matter loosened by the brush is permitted, While outside interference or entanglement of the animals hair with the brush is prevented.

2. rIhe combination, substantially ashereinbefore set forth, of the hand-piece casing, the' brush, the drivin g-connections carried'by the hand-piece to impart a turning movement to the brush, and the head or frame piece to which a shield or guard for said brush is connected, the head-piece being free to turn to accommodate itself and shield to the surface over which the brush moves.
