Application filed November 16, 1893. Serial Nol 491,177. (No model.)
To all whom t may concern.:
Be it known that I, WILLIS M. PRATHER, a citizen of the United States, residing at Kansas City, in the county of Jackson and'State 5 of Missouri, have inventedA certain new and useful Improvements in Apparatus for Oleaning Reservoirs,0isterns, &c.; and I do hereby declare that the following is a full,'clear, and exact description of the invention, such as will to enable others to make and use the saine, reference being had to the accompanying drawings, forming a part of this specification.
The objects of my invention are, tirst, to btain'a suction upon the impure water and the r sedimentary deposit at the bottom of the reservoir coextensive with the area over which the cleaning apparatus is made to operate; second, to enable the cleaning-arms to be extended over a greater or less area, in proporzo tion to the extent of the reservoir; third,
that the arms may rise and also fall into position automatically; fourth, to enable the ends of the arms supporting the folding cover to yield when brought into contact with the sides of the cistern.
My invention further consists in the novel construction and combination of parts, such as will iirst be fully described, and specifically pointed out in the claims.
In the drawings, Figure l is a vertical'sectional view of a cistern, showing the cleaning apparatus in position and the various parts in readiness for operation. Fig. 2 is a detail view of the lower end of the tube connected with the pump, showing the cover in section and the cover-supporting rods, and also the cleansingarms in an extended position, also showing in dotted lines the position of the said parts when closed upon the tube in en- 4o tering or being drawn from the cistern. Fig.
3 is a detail View in perspective of the perforated foot-plate, showing the lower end of the tube connected therewith, and also the pivoted receivers on both sides of the plate, with the curved rod carrying the series of perforated tubes and the clamps on the rods supporting the extension brushes in position.
. Fig. 4 is a horizontal sectional view of the foot-plate and receivers. Fig. 5 isa detail in 5o perspective view of one of the receivers. Fig. 6 is adetail view of the plate, showingabroken portion of one of the receivers. Fig. 7 is a detail sectional View of the end of one of the cover-supportin g rods, showing the adjustable r extension and the flexible attachments for the cylinder of an ordinary suction-and-force pump, which is arranged within and part way in a downward direction toward the bottom of the cistern or reservoir Z. To the lower end of the cylinder A is attached the upper end of a tube or liquid-conductor a, which also extends in the direction ofand nearly to the bottom of the reservoir and to the lowerend of which is attached the foot-plate B. Said plate extends downwardly to and rests upon the bottom of the cistern and in a horizontal direction an equal distance from opposite sides of the tube a. In a transverse direction to and in the plate B and directly beneath and in the line of the diameter of the lower end of tube a. is a circular opening b, in which said tube extends a short distance. (See Fig.` 3.) Upon one side of plate B, extending from the line of its upper edge and the side of the circular opening b, is a collar b', the inner side b2 of which extends partly around the tube to the opposite side of the opening b. The outer side b3 of said collar extends outwardly a short distance in line with its inner side from the same point of beginning upon one side of the'opening b, thence in a line parallel with and in the direction of the other end of plate B to within a short distance of the end of said plate, at which point the end of said collar is curved -downwardly and inwardly, as at b4. To the plate B, directly beneath lthe end b4, is a lug b5, which extends outwardly in line with the outer side b3 of the collar b', the under side of which lug describes a curved line from IOO other part of the collar, which also has an extension and a lug hs, which are precisely the same in construction as the first-described portion of the collar b and lug b5, the end of the curved extension of said collar, however, extending in the opposite direction from the collar b and toward the other end of plate B. The lug bs is provided with a perforation which extends through a plate B in the same manner as in lug h5.
On both sides of the plate B are hollow vibrating vessels or receivers C C', each one of which is made of the same height and length as the plate B. The end c of the receiver C opposite the lug h5 on the plate B is at right angles thereto and in line with the adjacent end portion ofrsaid plate. The outer side of said end extends in nearly the line of a full circle, which forms the neck c. From the square end c of the receiver the outer side c2 extends rearwardly to the other end and to the side of the plate B in a single outwardlycurved line, terminating at a point c3. The top c4 of the receiver extends from the point c3 toward the other end of the receiver and to the collar b in line with the side of plate B, thence describes the outward line of the said collar, and terminates with the circular outer side c ofthe neck at the other end of said receiver. The bottom c5 of the receiver describes the lines of the outer curved side cand also the line of the lower edge of plate B,and beneath the line of the neck c of the end c of the receiver C and extendingfrom said line to the side of plate B the position of said bottom at said point is bent upward and forms a stop at c, so as to extend partly around the the lug U1 and toward the wedge-shaped groove formed by the meeting lines of said lug and the curved end b4 of the collar ZJ. The inner side c7 of the receiver extends from the stop c beneath the lug h4, thence beneath the line of the opening h and a short distance past said opening, the edge of said side extends upwardly to the top c4, the remainder of said side extending in a parallel position with and close against the plate B. .A portion c8 of the neck c of the receiver extends within the receiver and from the top c4 downwardly to the bottom c5 and closes the opening from the neck c to the lug hs on the plate B. Extending throngh the plate B and the lug bs is a pivot o9, which extends through the neck c of the end c of the receiver C. The other receiver C is constructed in precisely the same manner as the receiver C and is pivoted to the lug bs of said receiver. These receivers may be made longer than the plate B, if desired. In the end c of receiver C is an opening cx, which communicates with the interior of the saidA receiver. At one side of the opening cX in the direction of the lug bs and in the end cof receiver C is inserted one end of a rod d of the cleaning-arm D, the other end of which rod extends outwardly as far as required and is bent forward in a curved Upon rod d is arranged a number of line.
short thimbles or tubes d d d. The tubes d d are placed endwise in position and at the receiver C are of a sufficient diameter to extend around the opening cX in the end c of the receiver. Toward the outer end of the rod d the series of tubes d decreases in diameter and at the extreme outer end of said rod are slightly larger than said rod. In each thimble or tube are made a series of perforations d3. yIn the thimbles or tubes adjacent to the end c of the receiver the perforations are made of a considerable size, and toward the end of rod D the perforations in the thimbles are reduced in size, as at (Z4. To the extreme outer end of rod D is attached a short piece of rubber hose d5. Extending around the rod d, between adjacent ends of the perforated thimbles d cl', near the receiver G is the circular end e of a thin clamping-plate E, in which is fitted an adjusting-screw e', which binds against the rod CZ. The other end of the plate E is forked, as at e2, and the forked portions bent in a downward direction a short distance. In one of the forked portions is fitted a clamping-screw e3. At the proper distance apart and upon rod (Z are arranged other clampingplatcs E, which are constructed precisely alike.
Between the forked portions of the clamps E E', and extending from the end c of the receiver C to the outer end of the rod cl is a scraper F, which consists of a fiexible plate, preferably made from rubber, which describes the curved course of the rod d and is clamped between the forked ends of the clampingplate E,the lower edge of the scraper extending downwardly to a position in line with the under side of the thimble d on said rod. Extending from the receiver C and its end c in an opposite direction to the arm D is an arm IOC D', which is constructed in precisely the same manner as the arm D. The weight of the receivers C C each exceed the weight of the respective arms D D', and each turns readily upon the pivot. Extending around tube a., beneath the pump cylinder, is a sliding flanged collar H, which is notched at required points in the line of the circumference, and in which notches are fitted the inner perforated ends of the respective rods h 7L 7L. The flanged collar H is made in two horizontallyseparate parts h h2, which are screwed together by means of the clamping-screws h3. The perforated ends of the rods h h are connected with the plates 7L h2 by means of a wire h4, which extends around the collar H, through the perforated ends of the rods n n and is clamped between the said plate h h2, thus holding the rods in a pivoted position. Beneath the collar H and around the tube a is extended a flanged collar Il, which is precisely the same as the flanged collar ll, and to which collar I-I are pivoted the lower ends of ribs h5 h5 71,5 in the saine manner as the rods hupon the collar II, the upper ends of which ribs are pivotally connected at h6 with the respective rods ata point equidistant IIO from the outer and inner ends. The end of each rib h5 for a short distance from the collar H is bent downwardly at k7 in a curved line, which facilitates the attachment of the cover hereinafter described. Around the outer end of rod h is fitted a sleeve extension I, in the side of which and at the end in which the rod h is inserted is a longitudinal slot 'L'. In the side of rod h and extending through the slott' is fixed a pin i. Within the sleeve I and attached fixedly at a point equidistant from the ends is a partition 2. On one side of partition t2, in the direction of the end of rod h, is a spiral spring 3, one end of which bears on said partition and the other against the end of said rod. Within the other end of sleeve I is inserted the interwoven inner ends k k of the separate spiral springs K K, which are secured within the said sleeve and against the adjacent portion of the partition i2 by the pin it, which extends through the sleeve I. The outer ends of each spring K K extend from the outer end of the sleeve Iin opposite directions and fold with the cover. Upon each one of the other rods h are similar sleeves I, constructed and arranged in like manner,vthe spring K K of each sleeve approaching quite near the springs upon an adjacent sleeve.
Acircular coverL, composed of preferably yielding material-such as canvas, rubber, or oil-cloth-is attached to the upper side of rod h, extending from the springs K K on one sleeve, to which the outer circular edge of the cover is attached by rings k2 to each sleeve in succession. Said cover extends to the pivotal point h6 of the ribs h5, at which point is an opening Z, through which the rods h h are extended outward and above the remaining portion of the cover, which portion extends to the collar I-I on the tube a and is secured to and around said collar by means of the clamping-bolts which secure the separate parts of the said collar together. Extending around tube a, at a point a short distance above the receivers C C', is an adjustable band or plate G, which is secured at the desired height by' the adjusting-screw g. Extending around the tube a, between the collars H H', and a short distance above the collar H when resting on the band G, is an adjustable band G', which is secured in position by the adjustingv screw g.
Instead of employing a rod d and placing the tubes d over said rod, I may make lthe tubular portion of the arm in one piece, or, as shown at h, in Fig. 9, extended part of the distance in one piece, which piece is loosely held in the opening c of the receiver C at one end, and in the other end an extension fm, smaller in diameter, is iitted so as to telescope. In this construction the'perforations are in the forward and under portions of the tubes and the scraper F also made in separate parts, and one part fitted within another in the same manner as the tubes M m. The clamps e2, which support the Scrapers, are arranged upon the respective tubes M m, and in advance of the tubes M m are brushes N N, which are secured to forward extensions of the clamp e2 and brush the sediment in advance of the tubes.
To the upper end of the pump-cylinder A is attached a short tube a', largerin diameter than the tube a, in the upper end of which is fitted adjustably to the lower end of a tube a2, the other end of which tube a2 extends upwardly through the circular opening z in the upper part of the cistern Z. Over the opening z is a movable platform S, through which passes loosely the upper end of the tube 0,2. Around the opening in the platform S for the tube a2 is a flanged seat t, in which is fitted the lower end of a rotary sleeve T', which also extends around and is adj ustably secured to the tube a2 by the set-screw t', and extends a short distance in height. To the upper end of the sleeve T is attached rigidly a ratchet-wheel T, in the upper circular edge of which are ratchet-teeth t2. In the extreme upper end of the tube a2 are longitudinal slots a4 M4, (see Fig. 8,) which are arranged a short distance apart and extend in series around the said tube. Around the said slotted end of tube a2 is fitted the pump-head U, in which the upper end of Vtube a2 rotates, and which is provided with a discharge-outlet u, which regulates alternately with each longitudinal slot 11,411.4. To the neck of the outlet u is attached the hose V by means of the usual hose-coupling. The upper end u2 of the pump head is perforated at M3, andv through-which is extended the upper end of the piston-rod 0,4, vwhich connectsl at its lower end with the piston in the pump A.
Upon the platform S and in a position a short distance from the pump -tube h2 is mounted a standard w, which extends a short distance in height and to which is pivoted the lower end of av pump-operating lever W. To
the lower end of lever W is attached rigidly one end of an extension-arm w', which extends in the direction of the pumptube a2 in an upwardly-curved line, and upon the upperl end and sideis pivoted with an eye wg, which is pivoted to said arm. To the upper end of the piston-rod d4 is attached a small clamp a5, in which is secured one end of the piston-operating rod X, which consists of two adjustable portions a: zr. The end of the portion w which is tted within the clamp a5 extends a short distance in ahorizontal direct-ion and is then bent in a downward direction and provided with a loop x2 at its lower end. 'The upper end of the other portion of the rod X extends through the loop x2, and is also provided with aloop x3, which extends around the portion x of the said rod. The two parts of the rod X are secu red adj ustably by means notches 104. Extending from each side of the lever W to the upper part of the ratchet-Wheel T are ratchet-operating levers 'w5 @05, the ends of which on both sides of slot w3 are clamped adjustably by the adj usting-nut and bolt w. The extreme outer ends of the levers a5 a5 are bent downward so as to form pawls, which engage with the ratchet-teeth of the ratchetwheel T. To the collar H of the cover-supporting rods is attached one end of a rope 71.7, the other end of which rope is extended upwardly through the perforation s in the platform S. In the operation of my improved cleansing apparatus, and particularly in its first introduction within the cistern, the parts are connected together, as seen in Fig. l, and both the cover and cleansing apparatus are in a closed position, as seen in dotted lines in Fig. 2. In this position the folds of the cover pass between the ends of the spiral springs K K on the respective rods h 72 and the cover is thereby folded within a small compass and enabled to pass within a very small opening provided in the cistern for the ordinary elevation of the water. The cleansing apparatus is also in a closed position, the weight of each receiver C C being sufficient of duty to cause the cleansing-arms to move upwardly and fold as close as possible against the folds of the cover L. In this position of the several parts the complete apparatus is lowered within the cistern, and as soon as the vibrating ends of receivers C C strike the bottom of the receiver, the weight is removed and by a slight torsion applied to tube a and the receivers the movement is communicated to the arms, which are extended outwardly and restupou the bottom of the receiver, and the cover L is also permitted to expand its fold and `gradually press the yielding ends of the rod h against the side ofv the cistern and cover the bulk of waterin the cistern so far above the cleansingarms D D as may be contaminated with sediment or floating animalculae. The lever W is then operated and suction is caused by the pump A to be exerted through the receivers C C', which causes a current which moves toward and into the said receivers, and simultaneous with the movement of the pump-lever rotation is imparted through the ratchet-wheel T and ratchet-arms 105 to the pump-tube a and the cleaning-arms D D described a circular line of movement on the bottom of the cistern, the separate tubes d rotating on the rod d and crushing the coarse material which obstructs its movement, and at the same time the curvature of' the arm tending to draw the larger material, which dissolves slowly, toward the receiver C C. The scrapers F as soon as the sediment is agitated prevent the passage rearwardly of any of the sediment and keep both coarse and fine matters subject to the action of the suction of the pump, and also to the disintegration by the tubes and the dissolving action caused by the agitation of the sediment, which later is more eifectually accomplished by the brushes in advance of the tubular parts of the cleansing-arms. The rotation of the arms brings into action the hose d5 on the ends of said arms, in which movement the sides of the cistern a short distance from the bottom are also in contact. When it is desired to cause suction through the arms, the construction is employed as seen in Fig. 9. The action of the pump is continued until the discolored water is entirely expelled, its place being taken by the clear water above lthe cover L, which finds its way past the outer` edges of the cover. As the water rises in the tube a it is discharged through the hose V, the head U remaining stationary while the openings register with the discharge outlet. In this manner the impurities in a cistern are removed from the water without removing only so much of the water as is necessary to the best results. When the operation is completed, the rope 71.7 is operated to draw the collar I-I in an upward direction and the folds of the cover together, which action brings the lower collar H against the band G and the rods h h are drawn together, and upon lifting the pump-tube from the cistern the receivers, which have also received the sedimentary deposits, are increased in weight by the deposits which remain therein and following toward the vibrating end assist the automatic action of the arms in closing upon 'the folds of the cover, as first described.
