ClSTERN-CLEANER AND WATER-PURIFIER.

SPECIFICATION forming part of Letters Patent No. 784,583, dated March 14, 1905.

i Application filed July 7, 1904. SBIIZLINO. 215,667.

To (Ll Z whom it may concern.-

Be it known that I, THOMAS S. MURRAY, a citizen of the United States, residing at Arkansas City, in the county of Cowley and State of Kansas, have invented a new and useful Improvement in Cistern-Cleaners and ater- Puriliers, of which the following is a specification.

This invention has for its object a device for cleaning cisterns and purifying the water therein by means of a simple appliance adapted to be easily rolled upon the bottom of the cistern, removing the sediment therefrom and purifying the water therein.

A furtherobject of the invention is to separate the water and the sediment, and the filtration, aeration, and consequent purification of the water, and the return of the same to the cistern or to some other receptacle, whereby the cistern is cleansed without waste of the water therein.

IVith these objects in view the invention consists in the novel features of construction and combination of parts hereinafter described, particularly pointed out in the claims, and shown in the accompanying drawings, in which Figure 1 is a perspective view of my device complete. Fig. 2 is a detail vertical section through the brush-easing and the cylinder, parts being in elevation. Fig. 3 is a detail sectional view of the handle portion. Fig. 4 is asection through the handle on the line 44; of Fig. 1. Fig. 5 is a section through the brush-containing casing and the cylinder at right angles to the section shown in Fig. 2. Fig. 6 is a plan view of the casing shown in Fig. 5. Fig. 7 is a detail perspective view of one side and corner of the casing, showingin perspective the parts carried thereby. Fig. 8 is a side elevation of the parts shown in perspective in Fig. 7, parts being shown in section. Fig. 9 is a detail sectional view through the dischargepipe and air-chamber. Fig. 10 is a detail sectional view of the packing around the lower edge of the casing. Figs. 11 and 12 are detail views, partly in section, illustrating a clutch mechanism. 13 is a (letail view, partly in section, of the upper end portion of a cylinder, puppet-valves being shown in elevation.

In constructing the device I employ a downwardly-open casing A, mounted on wheels A, and in the casing are arranged shafts B, having at one end and exterior of the casing sprocket-wheels B. WVithin the casing the shafts B carry brushes B adapted to rotate in opposite directions, as will hereinafter appear. Mounted upon the casing and journaled in suitable brackets is a shaft C, cranked as at C, and a yoke C of a handle C is mounted on the shaft C, the shaft passing loosely through the end portions of the yoke. The handle or pole C may be of any desired length and for use with deep cisterns may be formed in sections jointed or otherwise detachably connected. Adjacent its upper end the handle C carries a sleeve I), which extends upon each side of the handle and has bearings formed thereon, and on one of these bearings is journaled a pulley I)", and adjacent the pulley the sleeve D carries a horizontally-extending handle or handheld D and on the opposite side of the pole C the sleeve carriesa sprocket-wheel D adapted to be actuated by a crank-handle D". Above the sleeve the pole C has eyes E and E secured therein, the eye E being of greater diameterthan the eye E. The casing A has an opening formed in its top, over which is arranged a socket F, having an opening alining with that in the casing, the openings being closed normally by an upwardly-opening valve F, and a cylinder F has its lower end threaded into the socket F. In the cylinder F works a plunger F, having connected thereto an upwardly-extending plunger-rod F. The cylinder F -is arranged adjacent one end of the casing A, and adjacent the opposite end is pivoted a lever Cr, having an intermediate slotted portion G, through which extends the cranked portion of the shaft C, and the forward end of the lever Cr carries a preferably integral segment (1, and to the ends of the segment are pivoted the ends of a bail G, the bow portion of the bail being connected to the upper end of the plunger-rod F". From the side of the cylinder adjacent its lower end extends a dischargepipe H,

which extends upwardly, being passed through and supported by the eye E. The lower portion of the discharge-pipe may be of metal with hose connection, and the metal portion carries a laterally-extending cylindrical air- ,chamber H, communicating with the discharge-pipe H and in the pipe H adjacent the air-chamber, and between the air-chamber and the casing or lower end of the discharge-pipe is arranged a flap-valve H adapted to permit discharge of sediment from the casing A, but preventing its return. On the top of the casing is arranged horizontally a perforated pipe-section J, and a flexible tube J extends from an end of the pipe-section to the top of the cylinder F and is connected to'a nipple J carried by and opening downwardly into the cylinder. From the top of the cylinder F there also extends an air-pipe J carried by the eyes E, placed on the handle 0", the lower end of the pipe J being connected to a nipple J*, also carried by the top of tlie cylinder F The nipples J and J are provided with a commonform of puppet-valve J", the said valves being oppositely acting, whereby air is admitted into the cylinder F through the pipe J 2 and nipple J and discharged from the cylinder through the nipple J and pipes J and J. Sprocket-wheels K and K are carried by the shaft 0, and a sprocket-chain L runs over the sprocket-wheels D and K. A sprocket-chain M runs over the sprocketwheels K and B and over an idler M, the object of the idler being to hold the chain M in engagement with the rear sprocket-wheel B, the chain running over the wheels B, so as to rotate them in opposite directions.

To actuate the traction-wheels and move the casing A over the bottom of the cistern, the shaft A projects onone side and carries a gear-wheel N, which meshes with a wormgear N, the upper end of the worm-gear shaft carrying a pinion N and being journaled in bearing carried by a yoke O. The shaft 0 carries gears P, adapted to be engaged by the pinion N The yoke O is secured to a collar 0, sliding on the shaft (1, and the yoke also carries a laterally-extending arm 0 having rollers O mounted thereon. A cam-lever Q is pivotally mounted on the shaft C, the cam edge of the lever working between the rollers O As the lever is shifted backward and forward the pinion N is caused to mesh with one or the other of the gears P, thereby causing the casing to move backward or forward,

as may be desired.

- The lower end of the worm-gear is journaled in a pivoted lever B. A spring Sis connected at one end to the arm of the lever B and at the opposite end toan eccentric S. A red S is connected at one end to the eccentric, and a cable S extends from the free end of the rod S The cam-lever Q is actuated by a double cable Q, connected to the-free end of the cam-lever and running overa pulley Q A pull on one of the cables'Q moves the lever Q in one direction, and a pull on the other cable Q moves the lever in the opposite direction. A pull on the cable S lifts the worm-gear out of engagement with the gearwheel N. r

A strip of leather or other suitable packing is run along the lower edge of the casing, as shown at T, and is held down by a sack T, carried by the lower edges of the casing and weighted with shot, limiting the inflow of water to an amount suflicient to thin the sediment to be pumped out. Within the receptacle is pivoted at the rear end a receptacle U,

held in place by a hook U and having a screen U forming its front end, the object of the receptacle being to catch and hold any large objects which might clog the valves of the discharge pipe or cylinder. By means of this device the bottom of the cistern or of any reservoir or tank may be run over and scoured, the water being aerated, the sediment pumped out, and objects too large to pass through the hose will be thrown by the rear brush intothe receptacle U and held there until the casing has been lifted from the cistern or tank.

'I therefore pump out but a small portion of water to clear and purify a cistern a very' desirable thing during drought or when the supply of water is limited. J

The introduction of air into the water freshens it and gives it life, rendering it more palatable than water which has been standing undisturbed for a considerable length of time.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A device of the kind described comprising a downwardly-open, movable casing, a pump carried by and having communication with the interior of the casing, a dischargepipe leading from the pump, a perforated pipe carried by the casing, a tube connecting the said pipe with the top of the pump-cylinder, and an air-pipe leading from the top of the pump-cylinder.
