PRACTICING MACHINE FOR ADJUSTERS Fild Feb. 18, 1955 2 Sheets-Sheet 2 NVENTOR.I W%

A rroRzvam',

Patented June 30, 1936 T OF Fl CE -My machine relates to anewand useful machine or instrument for-use bylchiropracticstu 2 4. To provide such lanlinstrument lin "which thrust, torque .and recoil movements .may be practiced in rapid succession.

I accomplish these objects by the means illustrated in the accompanying, drawings, in which,

25 '.Figure 1 is an end elevationof my-v apparatus;

Figure 2 isa vertical section through .the middle of the apparatus as shown in'iFigure'l;

Figure '3 .is a plan view looking upwardly at the bottom of the apparatus;.and l 30 gure l is a side elevation of the groovedguide plates as they would appear if straightened out. Similar numerals refer to similar parts throughout the severalviews.

My apparatus comprises .a base,'9, which is preferably composed of a metalstamping, but maybe cast or otherwise formed of any desired material. The base'in general is composed of a 'flat platewitnflanges extending downwardly therefrom and triangular reenforcing plates, 9a, 40 united to the-loweredges of'the fianges at the corners.

A pair of-matched guide plates, l4, whichtogether form a cylinder, are mounted upon the base, '9, and-have lock pins, I lagunited to or 45 formed integral with-their 1 lower ends. 7 These lock-pins, Ma, are seated in suitable openings or bores, 9c,'formed in the top of the base and project through the 'base. Eaohlock pin is provided with a slot on its inner side just-below 50 the top"plate-iof theibase which-slots are-adapted to receive keysorlugs, IOc, formed upon the periphery of a gkeyplate jor locking :plate, 19, :zand'project laterally therefrom.

Aieolumn, :l, is seated; in a. suitable central 5 :opening in the top sioflithe base, :9, and: secured thereto by lock nuts,-8-and 8a, respectively above and below the top plate of the base. This column,

E, extends vertically upwardly approximately the height of the guide plates, l4, and a cap, .6, is

threaded upon the upper end thereof. 5 Within the column, 1,,a tube, 5, is mounted V which extends below the column, I, and forms ,a support for the locking plate, H), which is formed with a central opening through whichthe tube, 5, extends.

A nut, 12, is unitedlto the lowerend of the tube 5,.and may be secured'thereto bya pin, I3. A spiral spring, H, is .mounted encirclingth-e 7 lower end of the tube, 5, between thenut, l2, and the locking plate, I'll and acts to.,keep.the looking plate, l9, upwardin close contact with the top of the base, 9. The center of the locking plate, Ill, ,isformed with a central depression which allowsit to clearthe locking nut, 8a.

A rod, 2, is slidingly mounted in the tube,'5, and has a bushing, '4, united to its lower end to fit closely the inside of the tube,25. The pinfls, acts as a stop to limit the downward movement of the rod, 2, and thev cap, 6, acts asja detent to limit the upward movement thereof.

A spiral spring, .3, is mounted surrounding th rod, "2, with its lower end resting upon and united to the top plate of the base, 9, and its upper end united to a right-angle arm,,l5a, one end of which is united .to thetopofthe rod 2, and the opposite end of which carriesa plunger, l5, secured thereto by a set screw, l5b.

The spring, 3, is preferablylunited to the base plate, 9, and to the arm, E511, byspot-welding.

A head or scoop,'l,, preferablyformed of sheet metal, is united to the top'of the rod, 2, which has a head, 211, formed thereon. to secure the head,

i, to it. This head or scoop maybe of any desiredsize and conformation, but as the portion of .,the hand actually utilized to eifectuate a 40 chiropractic adjustment is usually that portion of the heel of thepalm adjacent the pisiform bone, I prefer to form the scoop or head, l,,of a

size corresponding to thatportion of the palm .of the operator. The scoop will therefore nor- "may be varied to meet the requirements of, different operators.

The curve of the head, |,-conforming to the curves of the contacting portion of the palm of the.hand,..gives:.the hand a-firm grip thereon and facilitates the torque movements hereinafter described.

The grooves shown in Figures 1 and 4 are to be regarded as illustrative of the direction and timing (as explained below in clause beginning That is) of the vertical and torque movements of the operators hand rather than as critical examples or as limitations of the scope of the apparatus. That is, the torque movement preferably comes approximately at the end of the downward movement. A variety of grooves will be provided for each machine and a plurality of plates, I4, having different forms of grooves, may be provided with each machine if. desired. It should be noted that the grooves indicate not only vertical movement, but also the torque or rotational movement and as the vertical and torque movements utilized in actual practice vary greatly, a corresponding variance may be provided in the different grooves of each series, as well as in the different series of grooves for the same or different machines. 7

The guide plates, M, are provided with substantially U-shaped grooves, Mb and Mc, of sufficient width and depth to receive and guide the plunger I5. The distance between the vertical branches of the U-shaped grooves may be varied to permit agreater or less lateral travel of the plunger and the slope of the bottom portion of the grooves may be varied in direction as well as angle so as to permit practicing the application of torque while the hand is still traveling downward or to permit the application of the torque after the downward travel has been completed upon the return movement. It may likewise be varied to permit the application of torque either to the right or left as desired.

This arrangement will permit and assist the application of torque at the desired point and in the desired direction and for the desired distance and the spacing of the U-shaped grooves will afford limits tothe torque movement beyond which it cannot pass.

For convenience, I refer to the downward movement of. the rod, 2, as the thrust and to the upward movement of the rod, 2, as the recoil and to the ro-tative movement of the rod, 2, as the torque.

The locking plate, It), is provided with an arm, ISa, which extends laterally therefrom and at the outer end of the arm, Illa, the arm is turned upwardly at IIlb and extends upwardly through the arcuate slot, 9b, formed in the top plate of the base, 9, which arcuate slot is constructed on a radius from the center of the column, I.

The arm, Ina, is so positioned that when swung to the right as shown in Figure 3, the keys or lugs, Iflc, will enter the slots, Md, and lock the pins, I do, rigidly to the top of the base, 9, thus securing the semi-circular. plates, M, in position upon the top of the base. When it is desired to change the plates, M, the locking plate, I0, is rotated to the left as shown in Figure 3 and the keys or lugs, IOc, are disengaged from the pins, Ma, thus unlocking the semi-circular plates, I4, and permitting them to be lifted off the base, 9. The bores, 90, are all of the same size and uniformly spaced so that the plates, M, may be moved to bring any particular U-shaped groove, Me or Md, into register with the pin, I5.

In the construction of my apparatus, a plurality of. springs, 3, may be furnished of different degrees of compressibility so that they can be changed to greater or less resistance as es ed- In the use of my apparatus, it is assembled with the spring, 3, of the desired resistance and the guide plates, I4 and Mb are adjusted so as to bring the particularly desired groove, Mb or Me, in register with the plunger, I5.

The hand of the operator is then placed lightly upon the head, I, where it may be suddenly pressed downward for the desired distance, carrying the plunger, I5, to the bottom of the adjacent groove, Mb or Me, as the case may be. At the bottom of the stroke or thrust, the torque or twisting movement of the hand is applied to the right or left as the case may be, sufiiciently to carry the plunger to the opposite vertical branch of the groove. The downward pressure upon the head, I, is then suddenly released and the recoil of the spring, 3, carries the head, I, back to its original position. It is well known that the natural elasticity of the back when supported by tables such as the B. J. Palmer Hi-lo, allows downward movements in the lumbar region of six inches or more and the elasticity of the tissues allows a very considerable torque or rotation of the operators hands without excessive rotation of the vertebra concerned. The apparatus disclosed assists the pupil to learn these motions.

It is obvious that the pattern of the grooves, Mb and I40, may be varied to provide for a wide variation in thrust and torque, both as to length and direction of travel.

My apparatus will thus enable the student to practice the entire range of manual movements utilized in chiropractic adjustments of the vertebraa and will permit the user to train himself substituted for various parts of my apparatus and I do not limit my claims to the precise structures shown in the drawings.

It is obvious that the top of the spring, 3, may be united either to the arm, I5a, or to the scoop or head, I, or directly to the rod, 2, and the lower end of the spring, 3, may be united either directly to the base, 9, or intermediately by being united to the nut, 8, or the column, I, and such attachment may be made by spot-welding and/or other suitable means.
