Application filed May 18, 1916, Serial No. 98,352. Renewed June 30, 1917. Serial No. 177,964.

To all whom it may concern:

Be it known that 1, WILLIAM C. J. GUIL- FORD, citizen of the United States, residing at Harrison, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Power- Operated Massaging Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in massage implements and has for its primary object the provision of a motor driven actuator designed to have air communication in order to control the manipulation of expansible massage elements, for example, the device illustrated and claimed in my companion application executed of even date herewith b'erial N 0. 98353, and wherein said device is specifically defined.

The actuator forming the special subject matter in the present instance, embraces the characteristics of compartments, portability, simplicity, and elliciency. In its general aspects the same comprises arommon supporting base having thereon and rigidly secured thereto an air storage tank, a pair of cylinders in communication with the massage implements,-preferably by flexible pipe connections,-and motor driven pistons for the cylinders. More specifically the relation of the operating connections be tween the pistons and the motor are such that the massage elements will be alternately expanded and contracted; and the expansion and contraction of the massage elements being preferably attained through the instrumentality of movable columns of air displaced,that is moved back and forth,-in consonance with the reciprocating movements of the pistons.

The improved details in the construction and association of parts will be readily appreciated from the specific description hereinafter contained when read in connection with the accompanying drawings forming part hereof, and wherein the preferred embodiment of the actuator is illustrated.

in the drawing:

Figure l is a perspective view of the actuator in its desired combination with the massage device;

Fig. 2 is a side view with part in vertical section; 7

Fig. 3 is an end view with part in section, and

Fig. 4 is a plan view of the actuator.

' Referring more specifically to the drawings wherein like reference letters designate the same parts in the several views, A represents a supporting platform or base of a readily transportable nature capable of be ing shifted from place to place by the operator or user, it being understood that the present device is susceptible of use without the necessity of an attendant by the patient, or other person subjected to the massage treatment. Upon the base I support in an n1 right position an air tank 13 within which is an air compressor or pump 0 the handle of which extends upwardly through the top of the tank within convenient access for use when the tank is to be filled, which can be ascertained at will by mere inspection of a pressure gage D connected by pipe E with the tank B. F are a pair of cylinders arranged in upright position and parallel relation at that end of the base A opposite to the end on which the tank B is mounted, these cylinders being seated in and secured to rings or cups G conforming in shape and size to the open lower ends of the cylinders, and integrally formed with brackets H secured to the base A near the opposite side edges of the latter. The tops or heads of the cylinders are fashioned to constitute outwardly projecting nipplesJ to which flexible,conveniently rubber,air conducting pipes or tubes K are secured, the pipes at their opposite ends being connected to a pair of massage elements or devices L, and adapted to discharge air into the sealed spaces be tween the base members Z of these devices and the expansible sheets or diaphragms on the inner faces thereof, which diaphragms, considering them in their complen'iental relation and intended operation effecting the passive massage of the same element or part of the body to be treated. T he special construction of the massage elements, here generally represented is defined in my previously mentioned companion application, entitled abdominal massage implement, but said massage elements may be of still other type or types for example as specially delined in my other companion application ontitled passive massage implement Serial No. 98351.

1 \Vithin the cylinders F are pistons M havingpiston rods N depending therefrom through the lower open ends of the cylinders F and through the open interior of the supporting rings or cups G, the lower ends of the pistons being in turn connected to oppositely disposed cranks O on a single shaft P mounted 111 and passing transversely through a housing on the base, the cranks,

alternate actuation of the massage elements or devices.

Unthe shait P and confined within the housing Q. is a Worm whee ltadapted to receive rotation through the medium of a worm S on a power shaft T driven from an electric motor or equivalent device U here shown as bein also mounted on the base A in the space between the tank B and cylinders F.

From the outlet pipe E of the tank B branch pipes V lead respectively to the upper ends of the cylinders F above the pistons therein, valves W cmitrolling the feed from the tank to the cylinders, the other valves I l interpc-id l si said valves \V and the cylinder. arcing exhaust from the cylinders and Massage devices when any given operation of the apparatus is completed and it being desired to reheve the pressure against the expansible elements.

The motor carries a flexibly connected plug Y adapted to engage a lamp or wall socket to electrically connect the motor with a source of supply, and interposed in the flexible connection for the plug Y is a hand switch Z for cutting the motor in and out of operation as desired, the hand switch being designed to be held in the hand of the patient or operator as the case may be. 1n

use the air pipes and cylinders are filled w' a air from the tank B when the respective pistons are in their withdrawn or lowermost positions, the controlling valves W being then off, thereby constituting in efl'cct an air piston or column behind an expan sible diphragm or sheets which air piston or column in its reciprocating movementeffected by the like movement o1 the piston will secure the alternate expansion and contraction of the massage element, and the close association of the power of massage elements with their alternate ex ansion and contraction with respect to each other obtaining the passive massage which the device is intended to accomplish.

While I have herein disclosed one particu lar embodiment of the invention it will be apparent to persons skilled in the art that said invention is capable of embodiment in still other forms and devices as may be in keeping with the hereto appended claims.
