PUMP.

Specification of Letters Patent.

Patented May 5, 1908.

Application filed September 14, 1907. Serial N 0. 392,866.

To all whom it may concern:

Be it known that I, HENRY G. RIEBENAOK, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and use ful Pump, of which the following is a specification.

The object of my invention is to provide a novel construction of a pump particularly suited for use with dust laden air and having pistons of rubber or other suitable resilient material and guiding piston heads.

A further purpose of my invention is to provide, in a vacuum pump, a piston chamer having concave outwardly facing walls and a piston of flexible material guided by the piston head in its inner and outer or extreme positions.

A further purpose of my invention is to so arrange a vacuum pump that a flexible piston operates toward and from a concave outwardly facing piston chamber having inlet and exhaust openings from said chamber and to also supply guides for the flexible piston.

For the purpose of illustrating my invention, I have shown in the accompanying drawings, one form of a device since this embodiment best illustrates the principles thereof and gives reliable and satisfactory results in practice, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown.

Figure 1 represents a vertical sectional view partly in elevation, the section being throu h the center of the pistons of a pump embodying my invention. Fig. 2 represents a broken end elevation of Fig. 1. Fig. 3 represents, in broken lan view, a portion of Fig. 1

Similar numera s of reference indicate cor responding parts in the figures.

Referring to the drawings, 1 designates any suitable framework, upon which I support my novel construction of a pump, said ramework being preferably elevated to give room for the mechanism of the pum beneath it, but this mechanism may evldent y be corres ondingly depressed with reference to the su ace considered if desired.

The framework 1 supports a plate 2, which may also be considered as a frame member,

but which in the form which I have illusv trated is made integral with and in this manner carries piston chambers 3 and 4, which are concave and outwardly faced at 5, which have depressions or ofisets forming the chain here 6, in each of whose base walls are a plurality of seats for valve parts for my mechanism the valves and seats thus being close to each other on said chambers 6 for quick 0 eration relatively to each other Within t 1e seats thus formed, I provide the inlet or suction pipes 7 and the outlet or discharge openings 8, these pipes and o enings communicating respectively with tie main pumping or suction pipe 9 and the water tank 10.

The inlet 7 and exhaust 8 are controlled by valves 11 and 12 respectively, the valve 11 being preferably of an ordinary flap or trap form, While the valve 12 is preferably of di rect vertical movement type guided in any suitable manner as by the stem 13, working within the supports 14 and normally held in upward position by the spring 15 which presses against a nut or projection 16 upon the upper end of the stem 13 and which at its other end presses against one of the supports 14. I preferably exhaust directly into a pipe 17, whose terminal 18 is placed below the surface of a supply of water 19 within the tank 10.

Since my device is primarily intended for exhaust cleaning purposes in which dust and dirt are gathered within an air carrier which may be attached to the suction 9 and pumped thereby, it is quite desirable to exhaust this air through the water, in order that the water may take up the dust and permit the cleansed air to escape to the atmosphere free from the contamination of the dust and dirt with which it was originally laden.

The piston chambers 3 and 4 are used in connection with flexible pistons 20, which are secured in position by an annular plate 21, secured by bolts or other fastening devices 22, the latter extending through apertures 23 in said plates. The piston 20 must not only be preferably flexible, but is preferably also elastic and is pressed to position at the downward end of the stroke by a piston head 24 conforming to the shape of the cooperating portions of the parts 3 and 4. Since these spherical portions 24 do not quite make contact with the corresponding portions of 3 and 4, they must preferably be formed upon substantially corresponding or similar radii. Said piston heads 24 are carried by any suitmounted upon disks 30, said cranks -,being mounted upon a shaft or shafts 31 which are driven by any suitable means such as the pulley 32. During the operation of pumping, the heads 24 press the flexible pistons into the position shown in the right hand of Fig. 1 thereby expelling the air from the piston chamber thereof. Upon the upward stroke the auxiliary piston head 33 which is also preferably of curved shape but small enough to pass within the opening 6, stretches the flexible piston to the position shown in the left hand portion of Fig. 1 thereby insuring full extension thereof and a corresponding complete filling of the piston chamber with air upon this limit of the stroke the same being effectively discharged with the dust, etc. into the adjacent chamber 3 or 4 and from thence forcibly directed to the dis charge valve 12.

The flexible pistons are thus alternately moved between the limits shown in the two positions of Fig. 1 with consequent filling and exhaust of the piston chambers and pumping action thereof and as both the piston and valve mechanisms are constructed in substantially the same manner, I have deemed it unnecessary to describe them in further detail.

It will be seen that the members 24 and 33 are reversely curved and are of such a curvature as to coact with the curvatures on which the piston chambers are formed, in that they preferably are portions of spheres having radii differing from the radii of the spheres of the piston chambers preferably by the thickness of the pistons 20.

It will be apparent that while I have described my suction pipe 9 as being adapted to be connected to a flexible hose having a dust collecting device thereon, I do not desire to be limited to this a plication of my invention, as the same can e ut to numerous other uses as is evident. t will also be apparent that the curvature of the parts 24 and 33 can be varied and that the pistons or diaphragms 20 can be connected to their operating devices by other means than those shown without departing from the spirit of my invention. It will also be ap arent that the precise construction of the va ves 11 and 12 and the manner of mounting and o erating the same may bevaried by those s 'lled in the art, and that the manner of trapping and purifyin the dust laden discharge may also e varied if desired.
