y TOALL WHoM rr MAY ooNonRN:

Be it k'nowuthat I, GEORGE H. TAYLOR, ot the city, county, and State of New York, have invented a certain new and useful oscillatory Rating-Machine for Medical Uses; and I do 4hereby dec-ure that the antw 1 ingis a full, clear, and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon. f i

The object of myinvention is to produce ei'fcctsfpn different parts ci' the-humanbody similar to those` produced by a rubbingnith the hands, and to produce these effects inan increased degree, but Without `the fatigue to' the 'operator occasioned by that operation. i i i i i i For this purpose my invention consists-7 Y A First, in -a new and improved rubber, hereinafter fully `described,"which, whenfloperated by any suitable mechanism, rubs the surface to which it is applied in su-ch amanner as to produce ,effects similar `to those produced'by the human hand.

` 1Second, in, the combination, `with the said rubber, ofv afforked arm or rod, .the forked endof which the said rubber is hung, the said rod being suspended on a pivot, andposcillated or vibl'af'ted in the same `plane with the axis of the said rubber, and in the general direction Yof its length.` e

Third, in the'combinatlon, with the said rubber and the saiclfrod, lof-'a` crank and connecting-barium*hrm,

by which alreciprocating motion is imparted' to the snidroid through a revolvinglshaft, du `which said crank is secured. y i

Fourth, in the combination, with the said rubber, andthe mechanical devices for imparting motion thereto,

.of a suitable couch, bed, or table, on which the person to be operated upon may sit or rec-liuc, the `said couch,

bed, or table having a suitable opening in it, through Awhich the said rubber muy be made-to protrude, in order that it'may be brought in contact with and caused to operate on that portion of the body of `the `pzitient which rests ou or across said opening. Y i l c In the accompanying drawings- Figure 1 isa plan of my improved machine. i

Figure? is a side elevation 4ot the same, a portion of -the couch being represented as broken away, in order to show the working-parts of the machine more-distinctly. i

Figure 3 is a'vertical cross-section' on the line xx, tig. 2, showingthe/working-purtstothe right of that line. i A is the rubber. It consists of a core ofwood, or other similar material, of the form of the middle frus-` tum of a prolate spheroid, somewhat resembling a very long cask 'or barrel. i On this core a triangular band of India-rubber is `wound spirally from end to end, covering its entire surface,rexcept'the ends, andsecurely fast,-

enved to the said core. l

A strip or band oflndia rubber, of a square section, may be used, by previously cutting out of the wooden core a triangular spiral groove, to receive one-half -of it. India-rubber bands of other shapes may'also be used in a similar manner, or the Iudiarubber surface, containing the requisite corrugations or projecting points,

cones, or ridges, to make it adhere to the surface to be operated upon, may be prepared 4in a. sheet of` proper size, and fastened on the core, or a. hollow cylinder of India rubber, having the requisite outer surface, may be stretched over or secured to the core, or upon the rod or pivot on which the rubber turns; In this `last case no core would'beneeded, but circular end plates, of metal or other stout material, ought to be put on at the ends `of the rubber to keep it in puce. f

This rubber, formed as described, is hung in the f ork B of ,the rod C, by means of the shaft or pivot D, so

as to turn freely. The red C is hung ou awpvot, E, in the cross-piece F, at any convenient height, being capa-V` ble of being raised or lowered by means of a series 'of holes, au, in any one of which the pivotE may beplaced. By shortening the upperend of the rodC, the lateral motion ot' the rubber is shortened, and the convexity of its motion is incr-eased. V

.The middle'part of theY cross-piece F is made double, as seen in fig. 2, and the rod C passes dovrn between4 the two parts, the pivot E passing through both,A so as to have a firm and even bearing.

The lower end of the rod C is connected to the double crank G by means of the arm or connecting-rod H, and thus hasn. reciprocating or vibratingmotion imparted to it by the shaft I, on which the crank G is hung.

The shaft 1 is turned by the crank Il. It may, however, bc turned by a trcadle, a drum and belt, or by cogge'aringg if preferred. The shaft is hung in bearings, K and L, in the hangers-M and N, and these hangers are secured to the frame of the machine by bolts b b. I

The 'lower part'of the machine consists of a strong rectangular frame of wood, O, with legs P, similar to a common lounge-frame, but having a cross-piece, Q, set into it, to stitfcn it and give a point of support to the hanger M. To this frnme,lat one cntl, is secured, by hinges c, a bed or couch, S, 'stuifed and upholstered, to

render it easy and comfortable for the patient, and having a hole or'opcning', R, through it, near its centre, to'

permit the rubber A'to Work against that portion of the body of the patient which is placed over the opening. Atthe end of the Acouch S, opposite to that secured by the hinges c, is hinged a rack, T. A loop or catch, U, v.rhich is hung or hinged to the frame O'by thc staples d, takes into the teeth ot' the rack T, and holds the said couch S at any desired elevation or inclination. Y Y

In using themachino, the patient sits or reclines on the couch, and brings that portion of the body, the leg for example, directly over `and partially resting upon the rubber The attendant now turns the crank '.I, -or

Y connects the power, by which the shaft 1I is revolved, and sets the rubber A in motibn.'

It will be observed thzt the motion of the `rubber is`pnrallel to the longitudinal outline-of itsA upper surface,and that in consequence the eifect is entirely a rubbing one. i

Having thus fully described my invention, I clain1 l u v l. The rubber-A, composed of India rubber, and having its outer surface coated or covered with India rubber, the suidouter surface being furnished with projecting ribs, points, er corrugations, and' the' said rubber A being constructed substantially as and for the purpose specified.

2. The combination, with the rubber A, of the forked rod C hung on ,a pivot, E, and opratefl .by any snit able mechanism, substantially as and for thepnrpose set forth.-

3. The `combination, with the rubber A and rod C, of the crank G, arm or connecting-rod H, and shaft I, substantially as described and for the pnrpose'set. forth. i v l r '4., The combination, with the rubber A, driven by suitable mechanism, substantially asset forth, of the couch S, properly connected to the franje O, and having an opening, R, through it, for the said rubber A tov Work through, substantially as and forthe purpose set forth.
