SUCTION PRODUCING PUMP Filed Sept. 19, 1933 N 9 I. a
Invenior E I'Z flmaoih iatented July 31, 1934 UN S A S:
PATENT OFFICE I 1,968,716 sUcTIon PRODUCING PUMP Earl l lonald Smith, Ashland, Ohio Application September '19, 1923, Serial No. 690,138 2 Claims. (01. 103--262) This invention relates to a suction producing pump, the general object of theinvention being to provide a pump adapted to be connected to a spigot or other supply of water and provided with means whereby the passage *of water or other liquid through the pump 'will create a pulsating and arrangement of the several parts-to be hereinafter fully described, illustrated in the accompanying-drawing and specifically pointed out in the appended claims.
In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-
Figure 1 is a view showing the pump attached to a spigot and with a tooth and gum brush attached to the suction passage of the pump.
Figure 2 is a longitudinal sectional view through the pump.
Figure 3 is a section on line 33 of Figure 2.
In these views, the numeral 1 indicates the pump which is formed of resilient material, such as rubber, said pump being formed with the exterior ribs 2 at its ends and with its lower end formed with the discharge nipple 3. A bore 4 is formed in the upper end of the pump for receiving the dischargeend of the spigot A, as shown in Figure 1, this bore having its walls iormed with one or more internal ribs 5 which act to firmly connect the pump to the spigot and provides means whereby the pump can be placed on spigots of different sizes. The upper end of the body of the pump is reinforced, as shown at 6. A substantially conical chamber 7 is formed m the body below the bore 4 and a conical nipple 8 extends into this chamber and has a passage 9 passing therethrough which communicates with the conical bottom part of the bore, as shown in Figure 2. The upper part of the cham- 'ber '7 is substantially cylindrical and a passage 10 leads from this upper part of the chamber through a side of the body, where it communicates with a nipple 11 of metal which projects -from the side of the body and is adapted to receive an end of a tube 12 which is connected with the attachment B which constitutes the applicator. Figure 1 shows this applicator in the form of a tooth and gum brush forming the subject z'5g'aimatter of the aforementioned patent. It will,
of course, be understood, however, that any form of applicator can beattached to the tube.
A relatively large chamber 13 is formed in the lower part of the body and a nipple 14 depends into the chamber and has a downwardly flaring bore 15, the small upper end of which is in communication with the small end of the chamber '7. The upper part of the chamber 13 is preferably rounded, as shown, and its lower end discharges into the nipple 3.
. A substantially cup-shaped member 16 is located in the chamber and its open upper end surrounds the nipple 14 and is spaced therefrom, the main portion of the member 16 being of cylindrical shape, with its lower end rounded and this member is connected with and supported from the bottom of the chamber by the Webs 1'7.
As will be seen from Figure 2, the entire device is formed preferably of rubber, excepting the nipple 11 and the reinforced fabric 6, and the parts are integrally connected together.
As the water escapes from the spigot, it will pass through the bore 4, the passage 9 and then through the bore 15 of the nipple 14 into the member 16. The water overflowing this member 16 will pass down the chamber 13 and then finally escape through the nipple 3. This passage of the water will create a suction in the chamber 7 so that air will be drawn from the applicator through the tube 12, nipple 11 and passage 10. V
The device is mainly intended for use with applicators for treating parts of the human body by increasing and stimulating circulation of the blood, removing foreign particles from difierent portions of the human body, such as pus, blood, etc. The action produced is a pulsating one, very similar to the human heart.
The member 16 acts to retard the flow of water, which increases the suction action, and said part or member 16 acts as a drum or balancer, as the water falling into the same causes it to vibrate in a rhythmic manner, causing a pulsation or a pull and push action. This pulsating action can be controlled by increasing or decreasing the size of said member 16 and also by increasing or decreasing the thickness of the walls of said part, as well as the legs or webs upon which it rests. This member being of rubber is, of course, flexible and this tends to add to the pulsating action by expansion and contraction. It should be constructed as large as possible so that it will hold considerable water and by having this large body of water within the pump, constant pressure is assured and with the air passage at substantially the center of the device, the pulsation action is increased.
The nipple 8 is, of course, also flexible and this member prevents any back flow of Water into the air passage and eliminates the use of check valves or the like. This nipple relaxes and contracts with the pressure and the breaking up of the water through the device and assists in steadying the flow of Water and it also causes a breaking up of the air pressure in the member 16. The nipple 14, with its downwardly flaring chamber 15, causes the water to spread out as it enters the member 16, thus permitting the water to gain velocity. This makes it possible to use a very short pump and assist in obtaining a steady flow.
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
What is claimed is:
1. A suction pump of the class described com-. prising a body formed of resilient material and having a bore in its upper part adapted to be connected to a spigot or the like, a chamber in its intermediate part, a lateral passage extending from said chamber to one side of the body, a depending nipple extending into the chamber and in communication with the lower end of the bore, a large chamber in the lower part of the body, a nipple depending into the same and in communication with the lower end of the first mentioned chamber, an outlet for the lower end of the large chamber, and a resiliently supported cup-shaped member of resilient material located in the large chamber and receiving the Water passing from the second nipple.
2. A suction producing device of the class described comprising a body having a bore in its upper end for receiving a spigot or the like, said bore having a conical lower end, a substantially conical chamber in an intermediate part of the body, a resilient nipple depending into the chamber and in communication with the said conical part of the bore, said body having a lateral passage therein extending from the chamber through one side of the body, said body having a large chamber in its lower end, a resilient depending nipple extending into the large chamber and having a downwardly flaring passage therein, the small upper end of which is in communication with the lower end of the first mentioned chamber, a cup-shaped member of resilient material located in the large chamber and having its upper part surrounding the second nipple, flexible Webs supporting the lower end of the cupshaped member from the bottom of the large chamber, and a discharge nipple at the bottom of the body and in communication with the lower end of the large chamber.
