     This invention is an improvement on my U.S. Pat. No. 3,762,410 granted Oct. 2, 1973. The foregoing prior art was cited during the prosecution of the above patent. (See Class 128, subclass 227.) 
     SUMMARY OF THE INVENTION 
     This invention is a portable irrigation apparatus for the colon and intestines with the patient sitting in a comfortable position on a toilet seat, the unit lying therebelow on the rim of the toilet bowl, whereby an undulating stream of warm water is injected by an enema tip which reciprocates in and out of the lower end of the rectum. This device is wholly portable and thus can be readily used from one point to another with considerable ease. This cannot be accomplished with the known prior art devices.

     DETAILED DESCRIPTION OF THE DRAWINGS 
     The device of the present invention comprises an enlarged rectangular plate 10 having a housing 12 anchored to one end thereof and extending upwardly from the plate 10 which houses a motor 14 having its shaft connected to reduction gears in gear housing 16. A shaft 18 from the reducing gears carries the circular cam 20 having four lobes 22. The cam is mounted to rotate on the shaft 18. 
     A cam follower 24 having one end bent on a radius 26 has its free end 27 bearing on one of the lobes 22, as shown in FIG. 6. To insure positive contact of the follower tip 27, a spring 29 lies against the follower body, as shown in FIG. 6, with the opposite end anchored at 31 to plate 10. The other or free end of the follower 24 is fixedly secured to an elongated rod shaft 28. The shaft 28 extends laterally, as shown in FIGS. 1-3, and is mounted in elongated spaced bearings 30, 32 formed by drilling the plate 10 lengthwise, one adjacent the follower 24 and the other adjacent the semi-circular cutout 34 in plate 10 to keep the shaft 28 in a horizontal position. The free end of shaft 28 is provided with a depending adjustable crank arm 36 anchored thereto and shiftable by reciprocation of the shaft 28. The free end of the crank arm 36 has right angled rod 38 secured thereto at one end to which a wide curved plate 40 is secured and extends at right angles thereto. A vertically extending guideway 42 depends from the under side of plate 10 and is anchored thereto by screws 44 to slidingly support a slider bar 46 for reciprocating movement in a vertical direction. 
     A cross arm 48 is anchored to the upper end of slide bar 46 and extends at right angles thereto and a bracket 52 is secured to the free end thereof. An enema tip 50 is carried in a support bracket 52 and is removably secured thereto. A flexible hose 54 is connected at one end to a warm water supply (not shown) and the opposite end is connected to the enema tip 50. 
     The motor 14 is connected to a source of current through plug 56 with an on-off switch 58 in the circuit. When the motor is energized, the cam 20 will rotate and with the rise and fall of the follower 24, cause the rod shaft 28 to reciprocate as one end of the follower is secured to one end of the rod shaft. 
     The reciprocating shaft 28 will also reciprocate the crank arm 36 which, in turn, because of the curved arm 40, will cause the rod 48 to reciprocate vertically. 
     The plate 10 is seated on the rim 60 of the toilet bowl 62 with the parallel rectangular cutouts 64 spanning the hinges 66 of toilet seat 68. When the toilet seat 68 is lowered to the rim 60, the rear bumpers 70 will seat on the upper surface of plate 10 to support the plate in horizontal position. Thus the cutout 34 will extend forward of the rear end of rim 60 to protect the guideway 42 slider bar 46. 
     Thus, when a patient is sitting on the toilet seat in a comfortable position, he merely energizes the motor by pressing the on button of the switch 58. With warm water flowing in tube 54, the enema tip will reciprocate in and out of the rectum in an undulating motion with the warm soft jet of water projecting in the alimentary canal and allowing for simultaneous intermittent discharge of waste products therefrom. 
     It will be understood that the device is so constructed that the enema tip will automatically position itself to be readily insertable in the anus as the enema tip extends above the plate 10 at the top of the stroke of the slide bar. 
     Upon completion of the treatment, the patient merely deenergizes the motor by moving the switch to off position and is free to arise from the seat 68. The device may now be readily removed from the rim of the toilet bowl, sanitized, and is ready for use by another patient. 
     The slide bar 46, the guideway 42 and the rod 46 are constructed of plastic, preferably Teflon or the like, for ease in movement to eliminate lubrication. Also, the plate 10 and housing 12 are preferably made from clear plastic for ease of cleaning. 
     Although but one specific embodiment of this invention is herein shown and described, it will be understood that details of the construction shown may be altered or omitted without departing from the spirit of the invention as defined by the following claims.
