SPECIFICATION forming part of Letters Patent No. 315,667, dated April 14, 1885.

Application filed October 20, 1884. (No model.)

To all whom it may concern:

Be it known that I, JOHN SERDINKO, of New Braunfels, in the county of Conrad and State of Texas, have invented a new and useful Improvement in Rotary Force-Pumps, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of one of my improved pumps. Fig. 2 is a sectional elevation of the same, taken through the broken line a: a: a: a: m m, Fig. 1. Fig. 3 is a sectional end elevation of a flexible tube shown open. Fig. i is a sectional end elevation of a flexible tube shown closed.

The object of this invention is to provide simple, convenient, inexpensive, and efiective pumps for raising water and other liquids.

The invention consists'iu a rotary force-pump constructed with a tubular standard provided with one or more flexible tubes having interior half-tubes and an interior cylinder mounted upon a crank-shaft and provided with adjustable bars carrying rollers, whereby a liquid can be raised by the successive action of the said rollers upon the said flexible tubes, as will behereinafter fully described and claimed.

A represents a tubular standard, which is secured at its lower side to legs 13, or other suitable support.

To the edges of the upper and lower parts of the standard A are attached the ends of ,crossbars G, to the center of which is jourualed a shaft, having a crank, E, attached to one or both its ends. The shaft D is placed at the center of the interior of the standard A, and to it is attached a wheel or cylinder, F, concentric with the standard A.

Through holes in the top and bottom of the.

standard A are passed one or more tubes, G, of rubber, or other suitable flexible material. When more than one flexible tube, G, is used, the said tubes should be placed at such distances apart as not to interfere with each other when flattened or compressed, as illustrated in dotted lines in Fig. 2.

Within each flexible tube G is placed a halftube, G, made of flexible material, and extending the entire length of said tube, so that when the tube G is flatted by the pressure of the rollers H, hereinafter described, the halftube G will close the said tubeHand prevent it from being injured by sharp folds in its sides, as illustrated in Fig. 4.

' H are three more or less cylindrical rollers, which run loose upon shafts I, the ends of which are attached to the outer ends of pairs of bars J. The bars J of each pair are pivoted at their middle parts to the outer parts of the ends of the central cylinder, F, and the inner ends of the said bars J are secured to the ends of the said cylinder F by thumbscrews K. The inner ends of the bars J are slotted to receive the thumb-screws K, so that the bars J can be readily adjusted to bring the rollers I nearer to or farther from the cen ter of the cylinder F, according as it may be desired to have less or more pressure applied to the flexible tubes G. The tubes G and rol1- ers H are so arranged that one or more of the said rollers H will always be pressing upon each flexible tube G, so that the liquid cannot run back through the said tube. The lower ends of the tubes G, when more than one are used, may all be connected with the same suction pipe or reservoir, or with separate snction pipes or reservoirs, according as one liq uid is to be raised, or more than one liquid. The upper ends of the tubes G maybe connected with the same receiver or with separate receivers, as may be desired. With this construction, as the cylinder F is revolved, the roller II will successively compress the tube or tubes G, forming a vacuum in the said tubes in the rear of the said roller, into which the liquid is forced by atmospheric pressure, and the liquid in the said tubes in advance of the said rollers will be forced out through the upper ends of the tubes.

Having thus described myinveution, what i. claim as. new, and desire to secure by Letters Patent, is

1. A rotary force-pump constructed subst mtially as herein shown and described, and consisting of a tubular circular standard provided with one or more flexible tubes having interior half-tubes, and an interior cylinder at tached to a crank-shaft and provided with ad justable'bars carrying rollers, as set forth.

IOU

2. In a rotary force-pump, the combination, with the tubular standard A and the flexible tube or tubes G, having interior half-tubes, G, of the interior cylinder F, the adjustable 5- bars J, the rollers H, and the crank-shaft l), substantially as herein shown and described.

3. In arotary force-pump, the flexible tubes G, made substantially as herein shown and described, with interior half-tubes, G, whereby the said flexible tubes will be kept from being 1c injured by having sharp folds formed in their sides by the pressure of the rollers, as set forth.
