3 Claims.
This invention relates to vertebral adjusters andlmore particularly to" an appliance designed for use by chiropractors in adjusting subluxations of the vertebrae by manual application to a patient by the practitioner.
The principal object of our invention is to provide an electrically driven vertebral adjuster havlng adjustable means therein to control the amount of force used in making vertebral adjustments.
Another object of our invention is to provide a vertebral adjuster having a trigger-actuated means therein for controlling the impact of force to be delivered against the vertebrae of a patient.
A further object of our invention is to provide a vertebral adjuster having superior driving, controlling, and impact means therein for the adjustment of vertebrae.
These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:
Fig. 1 is a longitudinal sectional view showing in elevation a device embodying the invention and showing details of the Working mechanism 25 thereof.
Fig. 2 is a top plan elevation of the cam lifter mechanism, forming a detail of the invention.
Fig.l3 is an enlarged cross-sectional View of parts shown in Fig. 1.
Fig. 4 is an enlarged cross-sectional View taken on line 4-4 of Fig. 3.
Fig. 5 is a plan View of a section of the shaft showing the torque imparting grooves therein.
Fig. 6 is a side elevation showing the relation between the trigger and cam lifting mechanism.
Our appliance comprises a-hollow housing I0, with a pistol grip handle II formed' integral therewith and set at a convenient angle thereto. A motor I2 is mounted beneath housing I0, and anozzle I3 extends forwardly from housing I0 andfis formed integral therewith.
On the upper surface of the grip II, an electrical switch'l4 may be attached by any suitable means such as screws not shown and an electricalfconductor I6 is attached to the switch I4 and extends into the housing I8 and passes through an aperture I1 in the base of housing I and is connected to the motor I2. The conductor I6 enters `the grip II through an aperture 22 in the base thereof.
In the lower surface of the grip I I, an opening I8 is provided for the reception of a trigger lever I9 which may be pivoted to the grip I I by means of a pin 20 extending through grip II. Attached to the rear portion of trigger I9is a tension spring 2I.` 'I'he one end of the spring is xed relative to the interior surface of the grip, and normally 'urges the trigger I9 outward from the pistol grip.
Pivotally attached to an arm 23 of trigger I9 by means of a pin 24, is a latch member 25 having a lug 2G at lthe upper portion thereof. A compression spring 21 is attached to the latch member 25 and to the arm 23 of trigger lever I9 and normally urges the latch member 25 to a forward position.
An offset plate 28 is attached to the interior surface of housingy IU by any suitable means. A channel 280 is provided in plate 28 through which a release pin 29 extends and projects therefrom. Pivotally attached to the middle of plate 2B is a cam lifter lever arm 30 which is pivoted thereto by means of a pin 3l. 'I'he cam, lifter extends rearwardly and has a notch 32 at its upper rear end which is adapted to engage with the lug 25 of latch member 25 when the latch member is` moved into a forward position. A spring 33 is attached. to the cam lifter 38 and to the offset plate 28 and normally urges the cam lifter downwardly from the offset plate.
In the middle of housing Ii), a plurality of bearings 34 are provided respectively in the in- `ner surfaces of the upper and lower portions of housing lll. A drive shaft 35 having `a key 36 thereon is rotatably mounted in bearings 34. Rotatably mounted on the lower portion of shaft 35 is a slotted gear 31 whichy is driven by the gear 38 on the end of a shaft 39 extending upward from motor I2 which is secured to housing I0 by means of screws 4U extending through the base of housing I0 and into the motor housing I2. Rotatably mounted above the gear 31 is a cam 4I having an upwardly extending collar42 and a release lug 43 integrally formed therewith. The central bore of cam 4I has a keyway extending therethrough which slidably engages with the key 36 on drive shaft 35. Slidably engaging in the collar 42 of cam 4I are the two arms 44 of cam lifter lever 3D whose connection with the actuating trigger I9 has been previously set forth.
Within the nozzle I3 is a slidably mounted impact shaft 45 having a longitudinal groove 46 on lthe periphery thereof and an oblique or spiral groove 41 extending substantially lengthwise of the impact shaft 45 but inclining in opposite directions from the groove 46. Aiiixed to impact shaft 45 near its rear end is a collar 48 `while a spring 49 surrounds the shaft 45 and abuts against collar 48 and the end of a bearing or bushing 50 within nozzle I3, and the spring urges the shaft in` a rearward direction.
A pin I passes through an aperture 52 in nozzle I3 and is held therein by means of a spring member 53 which is attached tothe nozzle I3 by anysuitable means. The pin 5I extends into the groove'46 or theA pin may be set in the oblique grooves 41 thereby imparting a right or left hand torque to the impact shaft-.45 when the appliance is operated.
A sleeve 54, one end of which is exteriorly screw threaded, is keyed to impact shaft 45, by key 55, and is slidably movable therewith and one end of the sleeve 54 may be inserted into the nozzle I3 and it extends forwardly therefrom. In screw threaded engagement with sleeve 54, is an interiorly screw-threaded` housing tip 56 having a nipple 51 upon its closed end. A rubber tip 58 may be attached to the nipple 5l' by any suitable means. Upon the forward end of impact shaft 45 and aixed thereto is a collar 59 which is adapted y to bear against a spring 55 which is placed within housing 56 and is positioned between the collar 5S and the interior of the head of the tip housing 56. rIhe relative position of housing tip 55 upon sleeve 54, controls the degree of compression of spring 5i] and thus the relative force with which rubber tip 58 operates on a patients vertebrae may be controlled. To lessen the force of operation of tip 58 the tip housing 55 should be positioned so that it is only in engagement with several of the threads on sleeve 54. On the other hand, when it is desired to increase the impact of tip 58, the tip housing 56 should be screwed well down onto sleeve 54- whereby spring 65 is compressed so that less of the impact of impact drive shaft 45 will be absorbed.
In operating our improved vertebral adjuster, the rubber tip 53 is placed against the patients vertebrae. The operator then closes switch la thus starting the motor I2 and causing shaft 3Q, gears 31 and 38, shaft 35 and cam 4l to revolve therewith. When it is desired to actuate tip 53 in order to adjust a patients vertebrae, the trigger .IS is pushed in thereby causing the latch member 25 to move forward and the lug 25 thereon to dog or engage with the notch 32 on cam lifter levei1 30 and depressing the spring 33 and causing the cam lifter arms 45 'to raise the cam il on shaft 35 so that the cam will contact the drive` shaft 45 thus causing the tip 58 to move outward thereby adjusting the patients vertebrae. When the shaft 35 has made one revolution, the release lug 43 on cam iii strikes the release pin 29 in offset plate 28. The release pin is pushed backward by this action against the upper edge of latch member 25 thereby disengaging lug 26 from notch. 32 and permitting the cam lifter spring 33 to force the cam 4l downward on shaft 35. so that cam M will revolve on shaft 35 below the end of shaft 45. In order to deliver another impact by tip 58 it is necessary for the operator to rst release his grip on trigger I9 and permit it to move forward and then push in the trigger I9 again when the next impact of tip 5B is desired thus again initiating the movement of parts as explained above.
Our improved. vertebral adjuster provides a device which is light and portable. It is capable of making eflicient and thorough vertebral adjustments and by means of the shock absorbing spring in the tip and the means for regulating the compression thereof, it is possib-le to regulate the degree of force applied to the tip 58.
Torque control of tip 58 is obtained by causing pin 5l to register with the proper oblique grooves 5i whereby drive shaft 45 will be turned within housing i3 as it is moved relative to pin 5l. Spring 53' retains pin 5| in proper alignment with a selected groove as 41 until such time as a positive force is exerted by an operator to change such a setting. l
With the foregoing and other objects inV View,
the invention consists in the novel construction, combination and arrangement of parts above described and illustrated in the accompanying drawings wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.
