SALEM LEON SCHLEPPY, OF CHICAGO, ILLNOIS.

PUMP.

Application filed November 18, 1.920.

To alt 'whom it may cof/werft.'

Be it known that I, SALEM LEON Soiimirrr a citizen of the United States, residing at Chicago, in the countyT of Cool; and State of Illinois, have invented certain new and 20 um s havino an' intermittent deliver P P e Y My invention contemplates the use of a series of impeller vanes driven continuously and uniformly,' drawing fluid between them,

and acted upon by meanswhich greatly de- .creases the fluid-chamber between the successive vanes as they pass the discharge ports thus compressing and expelling fluid into these ports, and then increasing` the fiuid chambers between the 'vanes as they pass the intake port, thus expanding the fluid into these chambers.

With the foregoing and other objects in view, mv invention consists'in the combination and arrangement of parts herein disclosed and shown and more particularly pointed ont in the claims, but it is to be understood-that changes in the precise em- -bodiment shown and described may be made without departing from the spirit of the invention as claimed in the claims hereunto appended.

Referring` more particularly to the draw-- ings. in which like reference characters indicate the same or siinilaipart-s throughout the views.

Figure l is a vertical longitudinal section of' the pump;

Figure 2 is a vertical section taken at Aright angles to Figm'e l, on the line 2--2 ot Figure l;

, Figure 3 is a fragmentary section taken on line 3 3 of Figuret;

-Figure .4 is an elevation von the line 4 4 of Figure 2 with' one ofthe bea-ringplates removed.

Serial No. 424,916.

Figure 5 is an elevation of the driving `gear assembly.

ln the drawings 1 designates the cylinder or casing of the pump which is preferably grovided with end plates 2 and 3, said end plates being secured to the casing by screws 4f, or other suitable equivalent means. Located in the casing wall are one or more pairs of intake and discharge ports, the intake and discharge' ports being alternately arranged. ln the embodiment shown. I have indicated two intake ports 5 and 5, and two discharge ports 6 and 6'. Suitable conduits T lead to the intake ports as shown, said conduits leading' the fluid to the pump from any suitable source of supply.

The pump is provided with a pair of drive shafts 8 and 9 which are so geared together that they are driven in unison and drive the synocket-wheels 10 and 11. These drive .shafts S and 9 are extended through the casing so as to drive a pair of sprockets which are duplicates of the sprockets 10 and ll and arranged on the opposite end of the drive shafts. Each of the duplicate pairs of sprockets drives a. series of rollers l5, at the ends of pivot pins 16 extending across the casing.

iiounted upon stub shafts 17 at each side of the casing7 are pairs of idlers 18,4

rf see Figures and il), said -idlers being arranged at. both sides of the rollers` as Shown in Figure et. It is to be noted that the pitch lines of the idlers are not in alignment with the 'pitch lines, of the drive sprockets but are arranged at one side of this line so that they engage the rollers and move them transversely or inwardly ot said line as they leave the drive sprockets, fora purpose to be hereinafter described.

Arranged within thel casting and mounted on the pins 1G are a series ofirigid impeller runes or blades the bases ot these Yanes being oil'set` as at i9, so as to form links exteni'ling rearwardly of the direction of travel of the vanes, each of the vanos being pivotally secured to adjacent pivot pins at two parallel spaced axes, one near each oi" the ends of the offset bases'or links. These ofi?- set bases arealso formed with'cutaway or recessed portions at their ends so as to interslock with the cutaway ends of adjacent vanes` as shown in Figure 2, wherein 20 indicates the oii'set portions of one vane and 21 indi- Cates the mating. or interlocking portionsof ers are engaged by said idler' to tilt the vanes intermediate the drivers and bringing them together to expel the fluid between them.

2. In a device of the kind described and in combination, a casing having intake and discharge ports, a series of spaced link-iinpeller vanes vin said casing, pivot pins pivotally connecting said vanes to each other, rollers on said pins, a pair of drivers en-v gageable with said rollers to drive said link-impeller vanes, an idler in the path of said rollers intermediate the drivers and havingits pitch line out of alignment with the pitch lines of lthe driveis, whereby the rollers are engaged by said idler to tilt the vanesl intermediate the drivers and positively move them transversely of said' idler, whereby the free ends of said vanes are brought toward each other to expel the fluid between them.

3. In a device of thekind described and in combination, a casing, a series of spaced impeller vanes pivotally linked together in said casing, an intake port for admitting fluid into the spaces between said vanes, an outlet port, a pair of drivers, an idler between saidv pair of drivers, drive rollers on said linked vanes, said rollers being actuated by said drivers and engageable with said idler, said idler being out of alignment with said drivers, whereby the rollers are positively moved transversely to said alignment line and causing the vanes to move transversely to said line, whereby said vanes are brought toward each other to expel the fluid between them.

4. In a device of the character rdescribed and in combination, a casing having a series of intake and discharge ports alternately arranged therein, a series of impeller vanes in said casing movable continuously past said yports in sequence, and separate means for positively moving the vanes to decrease the spaces between adjacent vanes at said discharge ports.

5. In a device of the kind described and in combination,l a casing, a series of spaced iinpeller vanes in said casing, `each of said vanes having a baseofi'set therefrom, backing members secured to the vback of each of said vanesI and converging to the tips of said vanes, an intake port for admitting fluid .into the spaces between each of said vanes, and the backing member of the adjacent vane, an outlet port, means for actuating said vanes whereby they are moved toward each other at said discharge port to expel the fluid between them into said discharge port.

6. In a device of the kind described'and outlet port, a pair of pinions for driving l said link-impellers past said ports, and separate means intermediate said pinions and positively engaging said chain to decrease the spaces between said impellers at said outlet port. i

7. In a device of the kind described and in combination, a casing having an intake anda discharge port therein, a series of link-impellers in said casing, linked together to form a continuous chain, means for driving said linkimpellers past said ports in sequence, and means for decreasing the space between at said discharge port, said casing having an inwardly projecting convex portion engageable with said impeller tips at said discharge ports.

8. In a device of the kind described and in lcombination, a casinghaving an intake and a discharge port therein, a series of link-impellers in said casing, linked together to form a continuous chain, a pair of'spaced driving pinions drivingly engageable with said link-impellers to drive them past said ports in sequence, said pinions spaced apart a sulicient dist-ance so that said impellers are free of engagement with -said pinions at said discharge port, and `means independent of said driving pinions for decreasing the space between adjacent impellers at said discharge port.

9. In a device of the kind described and incombination, a casing having an intake and a discharge port therein, a series of link-impellers Ain said casing pivotally linked together to form a continuous chain, each link-impeller comprising a vane portion with a link-portion base extending transversely of said vane'portion, means for driving said link-impellers past said ports in sequence, and means for rocking said im-l pellers on their pivotal axes at said discharge port to decrease `the space between Y the adjacent vanes, the tips of said vanes being arrangedto extend forwardly in the directionv of travel beyond either of said pivotal axesy of the bases of said impellers.

In' testimony whereof, I have hereunto signed my name in the presence of' two subscribing witnesses.
