i carried.
Another object of the invention is to provide a compound massage machine, that is one in which two plungers or vibrators will be arranged to always move in opposite directions to each other :so as to deliver a double vibration and eliminate vibration of the massage head.
Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efiiciency. These will become more apparent from the following description.
In the following detailed description of the invention reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.
In the drawing:
Fig. l is a longitudinal section through the massage head, taken on the lines II, Fig. 2.
Fig. 2 is a face View of the head, with a cover plate removed.
Fig. 3 illustrates the complete device ready for use.
The invention employs a head member I0 formed with a convenient handle I I. The handle portion I I is tubular to receive a shaft I 2 mounted in suitable ball bearings I3. The forward extremity of the shaft I2 carries two eccentrics I4 and I5, surrounded by suitable ball bearings I6. The eccentrics I4 and I5 are mounted in reciprocating members I? and I8 respectively.
The reciprocating members I 1 and I8 are similar to each other in size, shape, and weight. They reciprocate directly against each other in slidable contact, and are guided in a suitable guide groove I9 in the head member ID. The reciprocating members are held in place in the groove and on the eccentrics by means of a suitable cover plate which completely covers the groove I9 and the extremity of the shaft I2.
The ball bearings I6 are mounted in elongated bearing openings 2I formed in the members I7 and I8. The vertical width of these openings snugly engages the bearings I6. The horizontal width thereof is sufficient to allow for the movement due to the eccentricity of the eccentrics I 4 and I5.
It can be readily seen that as the shaft I2 rotates, the members I1 and I8 will reciprocate, in opposite direction to each other, once for each revolution of the shaft. The lower extremities of the members I I and I8 project below the head II] to receive sections 22 of a suitable rubber massage cup. The sections 22 may be secured to the members I I and I8 in any desired manner, such as by means of clamp screws 23.
It is preferred to form the members 22 so that the two together form a complete cup-shaped depression. In action, one side of the cup will rise while the other side falls to give a. rapid rocking or vibrating motion, which has been found to be exceedingly effective for massage and. therapeutic purposes.
The inner extremity of the shaft I2. rotates in. a bushing 24, which preferably extends beyond the handle member I I to receive a clamping nut 25 for attaching a flexible shaft housing 26. The housing 26 encloses a flexible driving shaft 21, as is usual in flexible shaft constructions. The extremity of the shaft housing 26 terminates in a flanged sleeve 28 having a tubular extremity 29 which extends within the bushing 24, to align the flexible shaft with the handle member II.
The flexible shaft 21 terminates in a tongue or keyed coupling 30, which passes into the extremity of the shaft I2 and engages a keyway 3| therein to transmit the power from the shaft 21 to the shaft I2. A suitable oiler is provided, as shown in Fig. 1, for filling the space about the shaft I2 with lubricating oil.
The shaft 21 is driven from a suitable electric motor 33, preferably mounted upon a wheeled platform 34, which allows it to be positioned convenient for the operator.
It is desired to call attention to the fact that the usual massage vibrating head has but a single motion, the reaction of which vibrates the massage head almost as vigorously as it does the patient. In the present machine, however, the reaction of the plunger I! is offset by the reaction of the plunger I8 and the action of the plunger I8 is similarly offset by the reaction of the plunger I1, so that there is very little vibration imparted to the head I0.
While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.
Having thus described the invention, what is claimed and desired secured by Letters Patent 1. A massaging device comprising: a head; a handle member extending from said head; an operating shaft extending through said handle and into said head; an eccentric formed on said shaft within said head; and a reciprocating member actuated by said eccentric, there being a guide channel within said head for guiding said reciprocating member, a second eccentric formed on said shaft from said first eccentric; a second reciprocating member mounted on said second eccentric in slidable contact with said first reciprocating member; and means for holding said members in said head.
2. A massaging'device comprising: a head; a handle member extending from said head; an operating shaft extending through said handle and into said head; an eccentric formed on said shaft within said head; and a reciprocating member actuated by said eccentric, there being a guide channel within said head for guiding said reciprocating member, a second eccentric formed on said shaft 180 from said first eccentric; a second reciprocating member mounted on said second eccentric in slidable contact with said first reciprocating member; and a cover plate on said head for holding said members therein and for maintaining said members on said eccentrics.
3. A massaging device comprising: a head; a handle member extending from said head; an operating shaft extending from said head; an operating shaft extending through said handle and into said head; an eccentric formed on said shaft within said head; and a reciprocating member actuated by said eccentric, there being a guide channel within said head for guiding said reciprocating member, a second eccentric formed on said shaft 180 from said first eccentric; a
second reciprocating member mounted on said second eccentric in slidable contact with said first reciprocating member; and means for holding said members in said head; a massage member formed in two parts, each part being con nected to one of said reciprocating members.
4. A massage device comprising: a head memher; a grooved channel extending longitudinally of said head member; a pair of reciprocating members positioned against each other in said channel; an operating shaft extending from said head at right angles to said reciprocating members; and eccentrics formed on said operating shaft at said reciprocating members, the latter having elongated openings for receiving said eccentrics.
5. In a massaging device, a handle member; a head member at one extremity of said handle member extending at right angles to and to one side thereof, a longitudinally extending channel in said head member open to the face thereof, said channel extending across the axis of said handle; a shaft extending through said handle; a pair of opposite eccentrics on said shaft within said channel; a first reciprocating member of a Width to fill said channel lying in the bottom thereof and provided with an elongated opening for the reception ofthe first eccentric; a second similar reciprocating member lying against said first reciprocating member in said channel and receiving the second eccentric; a cover plate closing said channel and holding said reciprocating members therein and also serving to hold said reciprocating members on their eccentrics; said reciprocating members projecting beyond said head and said cover plate; and a massage cup formed in two halves, each half being connected to the projecting portion of one of said reciprocating members.
