Leners Patent No. 106,061, ated August 2, 1870.

rMPRovEMENT I N RQTARY PUMPS.

The Schedule referred to in these -Letters Patent and `making part f the same.

Be it known that"IRonF.nT A. Ho'RNiNG, of Len' ark, in thecounty of Carroll and -State of Illinois, have invented anewand useful Improvement in Ro tary cam Pump.; and I do -hereby declare that the.

following is Va full and exactdescription of thesame,V i reference being had to the accompanying 'drawing and to the letters of .reference marked thereon.

`This invention consists .of certain' devices, to be'- `hereinafter more fullydescribed, forming what I call i a rotary-cam pump.

` YIn the drawing-4 Figure '1 isa plan vicwof the circular water-tight d 4compartment in which my cam revolves, showing the y valves and spring; 't

Figure 2 is a plan vof the cam, with Vpart of the upper Vcovering broken away tovshow the chambers-'or recesses inthe cam; y y

Figure Bis a "eticalsection taken through the cam ou a line of the passage'v leading to -the hollow Figure 4 is a front elevation of the pump attached to a suitable frame for support, and with spout above. i In vorder that those skilled in the art vto which my `invention more particularly pertains" may make and use the same, I will proceed to, describe the details of construction, referring/to` the`lettered parts inthe i figures.

The lowercase or chamberA, located` 4in anysuitablefouudation under fwater, is Vcircular in form, of.- "suitable depth, and is provided. with two sliding valves These valves move in slots, and are drawn forward by'V a spring, b, located beneath, and to which they are i attached onthe under side.

Within this chamber revolves, in a horizontal plane,

the cam B. This is made' of substantially the form shown, and is recessed at thefpart O, as shown.

VThis recess isdivided by a vertical partition from the vertex inward. On one side is a passageleading to the hollow shaft on which the cam is placed, and on the other an opening is provided through the upper shell from the chamber. The pivoton. the center of the lower side rests in a 'central step, d.

Over the cam is placed an inverted disk, D, the convex part being perforated to admit the water freely.

AThe plane bottonre of the disk `has a central opening `smaller than the cam,l but sufficiently large to ,include the oritice in the upper shell. This disk is secured to the lower case, and the shaft passes through it. The hollow shaftis rotated in any suitable manner, by crank, ratchet-wheels, or pulleys and band, and may have any convenient spout.

The'operation of my cam-pump is asfoilows: The cam being revolved to the right, the valves are held against the edge by their spring connection, and a vacuum is' formed forward of the valves which` vacuum `fills with water through the disk'or strainer. .At the same` time the revolution of the cam forces the watel'l into the chamber connected to 'the hollow l central tube, up the tube, carrying the water to any desired height.

Having thus fully described my invention,

What I claim as new, andV desire to secure by Letters Patent, is-

1. The described cam, revolving in suitable chamber,I having valves and recesses, one opening to the hollow shaftall as set forth.

2. In combination with the cam thusv constructed and ope1ating,the sliding valvesand spiral spring, all arranged `and operating as' set forth. v

. 3. In like combination, the disk or strainer, arranged as set forth. s

waterontside, and the other communicating with the This specification signed andwitucssed this 1st day of June, 1870.
