Application filed October 6, 1904. Serial No. 227,430.
To all whom t may concern:
Be it known that I, DAVID TRUMBULL MAR- SHALL, a citizen of the United States of America, residing in the city of New York,.in the county and State of New York` have invented an Improved Vibrator for Medical Use, of which the following is a specification.
The object of this invention is to improve the construction of vibrators for medical use, to cheapen and simplify them, and to permit the use of a small motor for the same without liability of stoppage of the vibrators action through undue pressure on the pad.
In the accompanying drawings, Figure 1 is a sectional side elevation of my improved device, showing a portion of motor attached. Fig. 2 is a face view of the fulcrum-collar, and Fig. 3 is a side elevation of a complete machine drawn to a smaller scale.
As shown on the drawings, M is the motorcasing.
S is the motor-shaft, carrying a plate P at one end, fitted with a disk D, adapted to be secured thereto by a screw s. Both disk and plate are provided with hemispherical recesses, which when placed together form a socket S' for the ball end B of the vibratorrod R, out of line with the axis of the shaft, and thus constituting a form of crank motion.
A cylindrical casing or tube T, open at one end, is secured to the motor-casing M by screws s2 and incloses the plate and disk of the motorshaft. A slidable collar or movable fulcrum f is fitted within one end of the tube T, being provided with a central opening o of polygonal outline with rounded edges and also with a depending threaded shank passing through a slot Zin the tube T. A thumb-nut N is used to tighten said collar in the tube and secure it in its various adjusted positions therein.
The vibrator-rod R is formed of a bar of polygonal cross-section for all or vpart its length, with which the central opening of the collar may engage. The rod is threaded at its outer end and provided with a ball B at its inner end. A pad or rubber P may bevv threaded on the rod R and secured additionally by a screw si. An open-centered protective collar c may be placed over the end of the tube T, as shown.
In assembling the device shown the collar may be placed on the rod R ,after the same has been passed through the opening in the hemispherical recess of the disk D andthe disk then secured in place against the plate of the motor-shaft. Then the tube T is slipped over the collar and the flanged end of the tube then secured to the motor-casing. The thumbnut N can be attached at any time. The protecting-collar is then placed over the end of the tube T and finally the pad or rubber P placed in position and secured.
In operation it-will be noted that a very small radius of throw is imparted to the inner end of the vibrator-rod from the motor-shaft, While the motion of the pad may be even less, according to the position of the fulcrum f. The pad is given an orbital motion, which may be so slight as not to be as great as the limit of elasticity of its own body. Hence no matter what pressure the operator applies it is practically impossible to stop the machine, the application of pressure to the patient, however, varying during each revolution.
I have shown my device as directly attached to the motor-casing, as that is my preferred form of machine. However, so long as any driving-shaft is coupled to my vibrator-rod in the manner shown I consider it within the scope of my broad invention.
From the foregoing description it is seen that I have invented a simple,cheap,and easilymanufactured device producing effective results in its intended use.
I claim as my inventionl. A vibrator, comprising a casing, a revoluble shaft therein, a tube secured to the casing, a collar having a hole of polygonal outline, a rod of polygonal cross-section passing freely through the opening, said rod having a cranked connection with the shaft and passing out of the tube and carrying a pad at its end.
2. A Vibrator, comprising a casing, a revoluble shaft therein, atube secured to the casing, a collar having a hole of polygonal outline and rounded edges, a rod of polygonal cross-section passing freely through the opening, said rod having a cranked connection with the shaft and passing out of the tube and carrying a pad at its end.
In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.
DAVID T. MARSHALL.
