DEVICE FOR REMOVING SEDIIVIENT FROM 4THE BOTTOMS 0F TANKS, CISTERNS, dc.

UFECIFCATON forming part of Letters Patent No. 307,323, dated October 28, 1884.

Application tiled October 2, 1883.

To all whom, it may concern: i

Be it known that I, J enr.T E, PATTIsoN, of New Orleans, in theparish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Devices for Re moving Sediment from the Bottoms of Tanks, Cisterns, &e. of which the following is a speciviication.

This invention is especially adapted to remove the sediment from the bottoms of tanks or cisterns situated below the surface of the ground for containing water, sugar-j nice, wine, or any other liquid, and from which the sediment cannot readily be drawn olf without the removal of all the contents of the eisteru or tank.

To this end ,my invention consists in the provision, at the end of a hollow staff of such length as to adapt it to extend to the bottom of theicistern or tank, of ahollow head having a brush or scraper for loosening the sediment from the bottom, and a door adapted to be operated from the top of the cistern or tank to admit the flow of sediment within the hollow head under pressure ofthe superincumbent mass of liquid.` A float within the head connected toa wire or rod extending through the hollow staff serves to notify the operator when the head is full of sediment and should be withdrawn from the cistern. l

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure I is a vertical transverse section of my improved device for removing sediment. Fig. Il is a side elevation of the same.

Y l represents the staff, preferably made in the form shown, having several joints or sections capable of being joined together by ferrules or rings 1, which may be smooth or adapted to screw to place on themeeting ends of the sections ofthe staff, to adapt the apparatus to cisterns or tanks of any depth. The said staff is hollow and opensfat its lower end into a chamber within the head 2, to the top of which it is secured by a screw-collar, 3. rIhe walls of the head 2 are preferably constructed in the form here shown of metal or wood. The head is provided at the bottom with a hinged door, Il, which has at or near its middle apin7 (No model.)

5, screwed or otherwise fixed thereto. The lower end of the staff 1 and the upper end of pin 5 are connected by a universal joint in such amanner that bythe raising or lowering of the staff (which is effected by screwing it up or down in the head) the door 4 may be opened or closed. Then in 'its closed position, said door bears on a' rubber or other water-tight packing on a frame, 6, in-the inside of the head 2, so as to make a water-tight joint. One of the lower edges, 7, of the head 2 is made to project somewhat below the level of the surrounding portion, so as to form a bearing for a scraper or brush, S. A slot, 9, in the lower end of staff 1 permits the egress ofairinto and through said staff. With-in the said slot also travels a cross bar, 10, fixed to afloat,11. To the center of the said cross-bar is fixed a wire or rod, 12, projecting up through the central hollow space in the staff, of such diameter as not to interfere with the free passage of air through said staff.

The following is the operation of my invention: The staff 1 having first been screwed up so as to firmly close the door 4 and convert the head into a water-tight chamber, the said head is lowered into a tank or cistern until it reaches the bottom thereof, the door then being opened by screwing down the staff to such an extent as to permit the ilow of sediment through the passage thus formed into the hollow head. In rushing in, the sediment will force out the air contained in said head, which air will rise through the center of the staff and escape. The implementis then moved slowly forward,

keeping the aperture in the head in front of and a little above the brush or scraper. The sediment, being banked up by the scraper, will be forced up into the interior ofthe head by the superincumbent mass of water until the air shall all have been expelled and the head be full of sediment. Vhen the water in the head reaches the float 11, said float will of course be carried 'upward thereby until it 95 IOO ing the top ol' the chamber, and that when said rod ceases to rise the water is at the top or within such a short distance thereof that by the time he closes the door the chamber will be full. Then sufcient sediment has thus been collected, the door 4 is closed by screwing up the staif l, the implement removed from the liquid, and the sediment allowed to run out by screwing down the staff and opening the door.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

l. Adevice for removing sediment from the bottoms of cisterns, tanks, &c., consisting of a hollow head having an opening, a door for closing the same, and one common handle for manipulating said hollow head and door, and

means for permitting the exit of the air therefrom, as set forth.

2. A device for removing sediment from the bottoms of cisterns, tanks, &c., consisting of a hollow head having a door, and a hollow staff for manipulating said head and door, and ai"- fording means for the escape of air from said hollow head, as set forth.

3. In a device for removing sediment from the bottoms of cisterns, tanks, &c., the combination of a hollow head, a hollow sta'li' verticallyadj ustable in saidhead, a door, and means for opening and closing said door at the will oi' the operator, as set forth.

+L.. In a device for removing sediment from the bottoms of cisterns, tanks, ttc., the combination, with a hollow head having a door, and a hollow staff for the purposes set forth, of a scraper or brush, arranged and operating as described.

5. In a device l'or removing sediment from the bottoms of cisterns, tanks, &c., the combination, with a hollow head having a hollow staff, of means, substantially as described, for announcing the height of the sediment in the hollow head, as set forth.

(i. In a device for removing sediment from the bottoms of cisterns, tanks, &c., the combination, with a hollow head having a hollow staii, of a 'fioat having a rod extending upward therefrom through said hollow staff, as'and `for the purposes set forth.

7. In a device for removing sediment from the bottoms of cisterns, tanks` &c., the combination, with a hollow head having a door, ol" a staff adjustable in said head, and having connection by a universal joint with said door, substantially as set forth.

S. In a device for removing sediment from the bottoms of cisterns, tanks, &c., the conibination, with a hollow head having a door, of astai'i" connected with said door, and adapted to be screwed into said head, as and i'or the purpose set forth.
