Be it known thzit ERNEST ASHLO K, citizenof the United States, residing at San Die' 0,ii1 the county of San Diego and State 6 of (ialifornia, have invented weeitaih new and useful Chiropractic Adjustment Machine, of whieh'theioHowing is a s ecifiest-ion.

' My invention relates to a machine for 1 makinghifbpia'cti'c adjustments and the ob= jee'tsof my invention are first, to provide a mOtOn'dri'Ven machine w ieh willbe eflective for roducing the proper" motions against-thehody for prodiieing' vertebrae ad- 16 justmehts, reiating to the science of chir'O-' reet-ie; second, to 'r'ovid a; machine OfthiS class which is eesilyzti 'd readily handled upon the: body of the-patient; third,'te rovide a 'mzihine' (if this class which is adjust- 20 able, ada ting it-foi ractically all purposes and positions in the chiropractic profession fduith, to provide a machine of this class which-is operated, -c1i1-eet1y by an eleetiie mo tor which may be Operated from any source of electrical ener'g'j fifth, to provide arde- Vice of this class which is very co pactin form and sixth-to provide a device Oi -this class which is very simp-1e,eeohemiee1 of construction, durabl easy to operate, efiident in its action, end'whieh will not readily' deteriorate or get out of order; I

Withthese and ether-objects in view as Will appeaihereinzifter, my inventionfcohs'ists of certain hovel features 1 of ohs'tr ie- 5 tion, combination and errshg'ei ent o-f parts and portiensas Wilibe' hereinafter described in detail and-particularly set forth in the appended claims, reference being had tothe accompanyin drawings-end to the chemo- 40 ter'sof refereficethei'e'on which form a, art

These" contact members 9, it will be noted, are preferably resilient members'composed preferably of rubber sufficiently resilient to produce the proper results. Adjustably mounted in, the frame 1 by means of setv sorews12 are the supporting posts 12 which it will be noted areprovided with right angle 'turns 12 upon which are pivotally mounted the bifurcated roller supporting members llfby means of adjusting screws 11 and mounted between the bifurcated portions'ofthe member 11 are rollers which are adapted to rest upon the body of the patient and support the machine in the proper position and conduct it on the body whilethe contact member 9 is reci-p-rocated by the motor forproducing a stroke like action on the body of the patient as desired. It fwillbe noted that with the particular post members 12 and supports 11 that these rollers 10 maybe adjusted so-that they are of varying width apart as ,desired and may 1 be caused to maintain certain positionsin advance or valong the side of the contact members '9 ormay; be adjusted to provide the proper str'okeof the plungermember 7 relatively to the body of the patient by moving the post members 12 upwardly or downwardly in the frame 1. v

Though I have shown and described a particular construction, combination and arrangement o'f p'arts and portions, I do not wish-to be limited to this particular con- 's'truction,;combinatio11 and arrangement,

, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims. v

I -It,'is obvious that withthis construction there is provided, a machine for making chiropractic adjustments on the vertebrae or [otherplaces as desired; that the members 9* are adjustable for different widths; that the plunger member 7'will be reciprocated in the frameand carry the members 9 backwardly forwardly providing a stroke action; thatthis stroke action may be regulated as to its length by means of the position of the rollers 10' relatively to the machine; that ;the crank 'wheel. 5 provides an increaseof power from the motor for direct action of th plunger 7; thatthe frictional contact between the wheel 5 and drive wheel 3 is provided by the spring 3*,through the pivotal mounting of the motor upon the frame 1;

that th device as a whole is very simple and economical of construction, durable, compactjm form and that the machinery is en- 'cased. 1

Having thus described my invention what ters Patentis, v j g j o 1.
