IMPROVEMENT IN sEwERs.
Specification forming part of Letters Patent No. 54,598, dated May 8, 1866. i
To all whom t may concern:
Be it known that I, THEODORE F. RAN- DOLPH, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Receptacle for the Sediment of Sewers; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to` the accompanying drawings, making parl: of this specification.
My invention is for facilitating the removal of dirt and olal ofV sewers, thereby saving nearly all the expense, danger, and unwholesome exposure incident to the present mode.
Figure l is a sectional perspective view of an ordinary catch-basin provided with myimprovement. Figs. 2 and 3 are top views, representing modifications of my receptacle.
A represents an ordinary catch-basin of a sewer, provided with the customary pitor depression B, inlet and outlet passages C and D, and man-hole`E. f
F F are movable vessels, boxes, or recepta cles, of galvanized iron or other suitable material, and so formed and of such dimensions as collectively to fill and occupy the pit or depression of a catch-basin, and yet be capable of ready withdrawal through the man-hole.
The central box, F is located immediately under the man-hole, and is provided with elevated ears f,.for the engagement of tackling G, employed to lift said box up out of the sewer The elevation of the ears f above the contents ofthe basin.
The other boxes, F', are located around the central box,F, and have ears f', to enable them to be lifted, one by one, out f thebasin and emptied and again replaced.
The boxes FF may be perforated to permit the escape of the water when the boxes are lifted, and for the purpose of enabling them to sink to their places when returned empty to the basin.
Movable bottoms maybe provided to facilitate the discharge of the contents of the boxes into a cart or otherwise, or the interiors of the boxes may flare upward for that purpose.
The boxes can be made ot any shape, to cor-` respond with the basin or excavation provided for detaining dirt in sewers for the purpose of y removal.
The ears ff may be replaced by bails.
Among a number of obvious advantages of my mode of removing the sediment from sewers the following may be cited: The work can be performed in a small fraction of the usual time, and mostly from the level of the street, with far less soiling of and danger and exposure to the operators.
An incidental advantage of my invention exists in the fact that the greater facility of the operation makes it practicable to clean out the basins at more frequently-recurrin g intervals.
I claim herein as new and of my invention- The arrangement, in the catch-basin of sewers, of removable receptacles F F', formed and adapted to operate substantially as set forth.
In testimony of which invention I hereunto set my hand.
THEODORE F. RANDOLPH.
