lip'plication 6166 January 5, 1907. Serial No. 351,032-

To all whom it may concern:

Be it known that I, JOSEPH S. C. LAU- RENCE, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful lii'iproven'lents in Vibrators, of which the following is a specification.

My invention relates to a massaging instrument, and especially to a device for applying massage to the scalp for the pur ose of stimulating circulation, preventing lialdness, and generally benefiting the health. Its object is to provide a device for applying massage to the entire scalp simultaneously and to produce a massaging movement which will be asnearlike hand-massage as it is possible to'get by mechanical means, which will be cheap, portable, light, and efficient which can'be run from the ordinary electric-lighting cir-' cuit, and which will perform the massaging function in far less time than can be done by any present known means, mechanical or manual.

The invention consists of the parts and the construction and combination of arts, as hereinafter more fully described an claimed, having reference to the accompanying draw in s, in which igure 1 is a side elevation of the invention. Fig.2 is a plan view of the same. Fig. 3 is an enlarged detail of the central support for the arches and slides with the top of the central support removed. Fig. 4 is a detail in partial section of a rib with a pair of the means for recipe Fig. 5 is an underneath rocating the ribs.

lan view ofgan applicator of preferred form.

. Fig. 6 is a detail in partial section of a clamplug-screw for securing the device on the head of the wearer.

A represents a bandto .encircle the head,

and 2 indicates a series of arches s ringing from this band and connected toget er to a I suitable central su port 3.

The band A, with its arched members 2 and connections 3, constitutes a crown-like structure adapted to fit over the head and .form a su port for the ap liances by which the actua 'massagin is one. This crown may be of anys'uitab e size or material. For the purpose "of lightness, strength, and rigid- 'ity it is preferably made large enoughto fit any size head, the device being adapted to the articular subject by means of the clamping evices a, as will be described later.

Parallel with eacharch .2 and suitably.

, from tur :four or more, are suitably adjusted to clamp mounted thereon for reciprocation is a curved rib 4. These ribs are here shown as having their lower ends movably seated in sockets 5 on the band A, with the springs 6 acting on the ribs normally to ress the latter upward. The upper end of each rib is movably housed in the central support 3 and carries a roller 7, engaging with the eccentric 8 on the driveshaft 9. By giving a rotary motion to the shaft 9'it will be manifest that the eccentric 8 will impart a reci rocating motion successively to the severa ribs, the springs 6 acting in 0 position to the cam to press the ribs normally inward and upward. The ribs 4 each carry one or more -appl1- cators, so called. Each applicator comprises a rubber or like soft flexi le pad 10, secured to the plate 11, which is carriedby the screw 12, operatingand guided in a slot 12 in the arch 2. The screw '2 engages a milled nut 13, which 1s mounted 1n aslot 111 a 11b in suchmanner as to be easily engaged by the fingers so as to raise orlower the applicator. By manipulating the nut 13 the applicator is made to bear. on the scal with ust the .right pressure. 14 is aloc -nut by which the screw 12 and applicator are prevented g after the proper adjustment has been effected by means of the nut 13. M0- tion may be im arted to the central shaft from any suitable source of ower. There may be any number of radial y-arranged reciprocating ribs, and each rib may be provided with any number of applicators, and

' these applicators may be of any suitable form of construction or material. I

In operation the device is laced on the head, and the screws 0, of w ch there are the device in position and prevent its move-- ment during the massaging o eration, each of the screws 0 being provlde with padded buttons a of suitable size and. design, which bear against the headsufiiciently to hold the device in position and. without causing discomfort to' the wearer. The several screws 12 of the. applicator are then adjusted to impinge with just theright pressure on that ortion of the seal immediately beneath.

n fact, one of the c ief features of this ma-' chine is that it permits a nice adjustment of the several applicators, so as to accommodate the device to the ine ualities of any head to which it is applied. Iaving effected the proper adjustment of the several applicators and lock them against turning on their tion may be kept up indefinitely.

axes by means of the locknuts 14 power is i applied to rotate the shaft There is thus produced a rapid reciprocatlon of the several ribs and a corresponding movement of the seal from the crown of the head downward in a 1 directions, the'motion of the several applicators'being such that there is produced E Mechanical massaging of this character is preferable to hand-massage, because of its uniformity and because the massaging opera- By suitably manipulating the adjusting-nuts 13 the precise pressure desired can be had, the massaging mademore or less vigorous, as c1rcumstances or conditions require.

The device is adaptable to anv size or sha e of head. It is cheap, portable, light,

an in actual practice has proven eminently practical and efficient. I

In practice the shaft will be operated by power derived from some suitable source and transmitted in any well-known manner.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is- Y 1. A vibrator comprisin a crown-like structure to fit the head, a p urality of independently-adjustable massaging devices carried by said structure, and means to operate said devices to produce a. massaging eil'ect.

,2. A vibrator comprising a crown-like structure to fit the head, a plurality of independently-movable massaging devices carried by said structure, means to operate said devices to produce a massagingeflect, and means for adjusting said devices toward and from the scalp.

3-. Avibrator comprising a suitable curved support fashioned to fit over the head, a reciprocating member on said support and conforming to the curvature thereof, an applicator carried by said member, andmeans for reciprocating said member.

4;. A vibrator comprising a crown-like structure, radiallyarranged reciprocating ribs mounted on said structure, applicators carried by said ribs, and means to reciprocate the ribs.

' 5. A vibrator comprising a' crown-like i structure, radially-arranged reciprocating l ribs mounted on said structure, applicators carried by said ribs, means to reci rocate the ribs, and means to adjust the app icators toward and from the seal 6. A vibrator comprlsing a suitable supi port to encircle the head, a reciprocating member mounted on said'sup ort and substantially conforming to t 1e curvature thereof, an applicator carried by said memher, and means to reciprocate the latter.

7. A vibrator comprising a suitable support to encircle the head, a reciprocating member mounted on said support, an applicator carried by said member, means to reciprocate the latter, and means for adjusting the applicator toward'and from the scalp.

8. A vibrator comprising a crown-like structure, a plurality of radially 7 arranged reciprocating members thereon, means for reciprocating said members, and massaging devices carried by said members.

9. A vibrator comprising a crown-like structure, a plurality of radially-arranged reciprocating members thereon, means for reciprocating said members, massaging devices carried by the members, and means for independently adjusting said several massaging'devices toward and from the surface to be 0 erated on..

10. vibrator comprising a crown-like structure, radially-arranged ribs on said structure, said ribs spring-supported at one end, means acting on the opposite end of the ribs to impart a reciprocating motion thereto, and massaging devices carried by said ribs.

11. A vibrator comprising a crown-like structure, radially arranged ribs on said structure, said ribs spring-supported at one end, means acting on the opposite end of the ribs to impart a reciprocating motion thereto, massaging devices carried by said ribs, means for clam ding said structure to the part of the bory to be operated on, and means for adjusting said massaging devices to accommodate them to the surface to be operated over.

Intestimony whereof I have hereunto set my hand in presence of two subscribing Wit- IIGSSGS.
