`To all whom t may concern MASSAGING IMPLEMENT.

:Be it known that I, RAYMOND lV. Giiiririi-i, acitizen `ci the United States, and resident ofvMilwaukee, in the county ofMilwaiikee *and* State of'lVisconsin, have invented cery tain newand useful Improvements in Mas saginglinplements; and 1 do hereby declare that the following is a `full, clear, and exact description thereof.l y

`My invention consists` inlwhat is-hereiii particularly set forth `with'reference to the accompanying .drawing fand `pointed out in the claims of thisfspecifieation, its object being 4to sinipliivandfcheap'en -the vacuum Vibrator massaging implement specified in n'iy LettersPatent- No. 996924, granted July `The drawing represents a centra-l 4longi-` J tudinal section ofA onelof'lmy improved vacu# um vibratorsjhaviii'g arsiiction-ciip applicatorapplied thereto;

Oppo-` ,site its 'boss 8, the cylinder is provided with an 'outer lug 12 havitigintrsecting bores 131. and 14,` at right-angles; "thel bore 14 being coiintersunk. VThe bored lug` 12 constitutes the inlet of thecylinder and a hollow boss extension 15.0f said'lug is in line with the bore 13 of thesame.

Engaging the countersink ofthe lug-bore disks 19, of felt or other-suitable material, is shown the hollow shank 20 of a suction-cup 21` but 'any other form of applicator may be utilized.

A floating piston22 of suitable weightI is guided in the cylinder. The piston is provided with an outer annular preferably V.-i shapedv groove 23 midway 0f its ends, and with a pair of transverse passages 24 that are equi-distant from said groove in opposite directions, each passage being alternately registrable with a cylindenport 25. and the exhaust of the cylinder.` Each of. the piston-passages 24 is intersected by a l counter-sunklongitudinal. bore 26 of the piston, and engaging the countersink ot' each' of these bores `1s a spiral spring 2l'y consti.-y

'In the operation of my vaccumvibrator,

airis exhausted from one end of the cylinder 5 through a bore 2G4 and passage 24 of the piston t en-ln communication with the inlet and exhaust of said cylinder, while at,thef.

said cylinder through a port 25 of the saine then in register with a passage 24 `of saidl piston. The result is a` rapid movement of the piston to the vacuum-end of the cylinder; `whereupon an immediate reverse movement ofsaid `piston takes place, its reciprocation 'same time air is admitted to the other end ofi y being against resistance of the`.elast ie`y cushions that serve, by compression, to" limit thepiston-movement in opposite directionsas welles to render the apparatus practically noiseless.` The` automatic rap'id reci-procation `of the piston effects the-vibrations desired,.its groove 2B being a lead-that prevents cutting off the suction through the cylinder, Aand incidental to the suction, the i lubricant 16 is supplied tosaid cylinder and thepiston in'sii'flicient quantity.

There is animmediate reverse stroke of the piston, and continued reciprocation ofthe same as long as the suction through the pipe 9 continues. The path of reciprocation Aof the piston is short, but sufficient to produce the vibrations necessary for mas- 1. .In a vibrator massaging implement,` the combination of a cylinder. having an inlet arid exhaust midway of its ends, as well as ports inu opposite directions fromvsaid inlet and exhaust, the aforesaid inlet being 'forjthe engagement of the. shankof an applicator; and a iioating. piston in the cylinder provided with an outer annular groove midway of its ends, Va pair of Vtransverse passages equi-distant from said groove in opposite directions. and bores intersecting the passages; each passage being intermittently` regstrable I with a cylinder-p ort.
