STEIN RECEPTACLE FOR CATCH BASINS OR THE LIKE Filed Oct. 24, 1955 2 Sheets-Sheet 2 Patented Nov. 24, 1936 UNITED STATES RECEPTACLE FOR CATCH BASINS OR THE LIKE Hyman Stein, Chelsea, Mass. Application October 24, 1935, Serial No. 46,574
This invention relates to a receptacle for a catch basin or the like, and it is an object of the invention to provide a receptacle or container of this kind to be placed within a catch basin of a sewerage system to receive and retain the heavy road detritus so that such detritus will not enter the sewer and by deposit therein impede the flow through the sewer.
Another object of the invention is to provide a receptacle or container of this kind which is readily removable from within a catch basin with a minimum of labor and whereby it is possible to maintain a sewerage system at a high state of efiiciency with but slight cost in comparison with the manual spooning out of catch basins now generally in use.
The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved receptacle for a catch basin whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.
The novel features of my invention will hereinafter be definitely claimed.
In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:-
Figure 1 is a view partly in section and partly in elevation and of somewhat a diagrammatic character illustrating a receptacle constructed in accordance with an embodiment of my invention and in applied position;
Figure 2 is a vertical sectional view taken through the receptacle as illustrated in Figure 1 with a second position of the bottom plate indicated by broken lines;
Figure 3 is a view in bottom plan of the structure as illustrated in Figure 2;
Figure 4 is a fragmentary view in perspective illustrating in detail the locking means for the bottom plate as comprised in Figures 2 and 3;
Figure 5 is a view in perspective illustrating another form of locking means for the bottom plate;
Figure 6 is a view in perspective illustrating a still further means for locking the bottom plate;
Figure 7 is a view in elevation illustrating a form of receptacle comprising only a single hoisting member.
In the embodiment of my invention as illustrated in Figures 1 to 4, C denotes a conventional type of catch basin employed in a sewage system and with which communicates at a predetermined point above its bottom the street inlet S. This catch basin C at a desired point also above 7 its bottom is in communication through the line 5 L with a sewer A proper. The line L immedately adjacent its communication with the catch basin C is provided with a trap T whereby the liquid level within the basin C is normally maintained substantially flush with the lower point of com- 10 munication between the inlet S and the basin C. Snugly but freely fitting within the basin C is a receptacle or container R constructed in accordance with an embodiment of my invention, said receptacle or container R being of a height to have its upper open end terminate adjacent the low point of communication of the trap T of the line L with the basin C when the receptacle or container R is'resting upon the bottom of the basin C. The receptacle R has its peripheral or side wall formed of sheet metal preferably varying between six gauge and fourteen gauge in accordance with the size of the receptacle or container, and said wall I is preferably formed of one sheet of material having its abutting edges welded together, as at 2, or as illustrated in Figure '7, said abutting edges of the wall may have disposed thereover the lapping strip 3 riveted, as at 4, to the adjacent end portions of the wall or otherwise secured thereto to maintain the wall I in desired formation and assembly.
The receptacle or container R is also preferably tapered from one end to the other with the larger end uppermost. This'form is provided to facilitate the application and removal of the receptacle or container R within the basin C. It is to be stated, however, that the upper or larger end of the receptacle is of a diameter substantially equal tothe interior diameter of the basin C so that when the receptacle or container R is in applied position within the basin C it will receive and collect substantially all of the heavy road detritus discharging into the basin C from the inlet S."
At opposite sides of a diameter of the receptacle or container R at the top thereof and at aligned points are secured by welding or otherwise as may be preferred the extremities of the upstanding hoisting members H. Each of these members is substantially in the form of an inverted V and the apex portion of one of such members is disposed on an incline toward the apex portion of the other member with said apices in such close proximity to permit the same to be engaged by a hoisting hook such as com prised in the block and fall of a portable hoisting mechanism. By the means of this portable hoisting mechanism the container or receptacle R may be readily and conveniently removed from or placed within the basin C within a short period of time and at low cost. It is also believed tobe obvious that through the medium of a portable hoisting mechanism a single crew can remove, empty and return a considerable number of receptacles or containers R during the course of an average work day.
If preferred, a single hoisting member H may be employed as illustrated in Figure 7 and when so used this member H is disposed diametrically across the top or upper end of the receptacle with its angularly related arms substantially coplanar.
Welded or otherwise secured to the lower portion of the receptacle R at diametrically opposed points are the straps 5 extending beyond the lower end of the receptacle to provide short supporting legs. Also welded or otherwise secured to the wall I of the lower portion of the receptacle R at diametrically opposed points and in alignment substantially at right angles to the alignment of the straps 5 are the additional straps 6 which also project a slight distance beyond the lower end of the receptacle R to provide relatively short supporting legs, the outer ends of the straps or legs 5 and 6 being substantially coplanar.
The lower or smaller end of the receptacle R has associated therewith a bottom closure plate I which fits substantially snug within the lower portion of the receptacle B. when in closed position. Disposed diametrically across the outer face of the plate I and welded or otherwise fixedly secured thereto is a plate 8, said plate extending from one notch 9 to another of such notches 9 provided in the periphery of the plate 1. Each of these notches 9, as is particularly illustrated in Figure 3, is of a size and form topermit the desired swinging movement of the plate I without hinderance or obstruction being offered by the legs i'until a shoulder I provided by an end edge of each of the notches 9 comes into contact with a leg 5. The outer portion of each of the legs is, as particularly illustrated in Figure 2, reduced in width, as at II, so that the plate In may have its swinging movement to an extent desired.
The plate 8 at its ends has extending therefrom trunnions -I2 which engage within the legs 5 whereby the bottom plate I is supported for desired swinging movement into either open or closed position.
The movement of the bottom plate 1 into its closed position is limited by contact of the outer end portion of the swinging arm I4 pivotally connected, as at I5, to the bottom plate I and which is of a length to extend beyond the peripheral edge of the plate I for contact with the bottom edge of the wall I as the plate I swings to closed position. This arm I4 when the bottom plate I is in its closed position swings into a notch I6 provided in one of the legs 6 immediately adjacent to the lower edge of the wall I whereby the bottom plate I is effectively held in its closed adjustment. To assure the maintenance of the arm I4 within the notch I6 a dog I1 is pivotally connected, as at I8, to that side of the arm I4 oppositeto the leg 6; said dog swinging into close contact with the arm I4 to hold said arm I4 within the recess I6.
As illustrated in Figures 3, 4 and 5. the straps 5 and 6 are secured to the inner face of the wall I and the peripheral portion of the plate I is provided with another recess I9 to permit the plate I to swing into closed position without obstruction being offered by one of the legs 6. Substantially diametrically opposed to this recess I9 the peripheral portion of the plate I is provided with another recess also of a form or shape to permit closing of the plate Ill without obstruction by the second leg or strap 6 and also formed to prevent hinderance or obstruction to such closing of the plate I being offered by the suction release pipe 2| extending through the receptacle R and to be hereinafter more particularly referred to.
In the embodiment of the invention as illustrated in Figure 5, a strap 6 is shown secured to the outer portion of the wall I of the receptacle R. and the outer or extended portion of this strap 6 is laterally extended, as at 22, to provide in connection with the lower edge of the wall I a recess I6 to receive the outer portion of a swinging arm I4 carried by the bottom swinging plate I. This arm I4 is held in place within the recess l6 by a swinging latch 23 pivotally engaged, as at 24, with the wall at the lower part thereof and which latch has a lateral extending part 25 to engage beneath the arm I4.
In the form of the invention as illustrated in Figure 6, the leg 6" is also secured to the outer face of the wall I of the receptacle and the. extended or leg portion of this strap 6 is provided with an opening 25 to receive the outer end portion of a sliding bolt 2'! carried by the swinging arm i4". In this embodiment the bolt 21 provides means for effectively holding the bottom plate 7 closed.
The suction release pipe 2| is held in desired position by the blocks 28 interposed between the pipe 2| and the adjacent wall I of the receptacle R and welded or otherwise secured thereto. As disclosed in the accompanying drawings, this pipe 2| is disposed substantially parallel to the axial center of the receptacle or container R, and is of a length to have its upper end terminate above the water seal when the receptacle or container R is in applied position within the basin C as clearly illustrated in Figure l of the drawings.
Insertable through the pipe 2| is a rod 29 of a length, as illustrated in Figure 2, slightly longer than that of the pipe 2 I, and the upper or outer end of this rod 29 has fixed thereto a cap 30 to engage over the upper open end of the pipe 2| and to assure an efiective closing of the upper end of the pipe 2| by the cap 30 a gasket or washer3| of rubber or kindred yielding material is fitted within the cap 30 for direct contact with the upper end edge of the pipe 2|. The lower or free end portion 0 fthe rod 29 has fixed thereto a surrounding washer or head 32 of a diameter substantially equal to the internal diameter of the pipe 2| and which washer or head 32 when the rod is in fully applied position is arranged within the pipe 2| closely adjacent to its lower end.
When the receptacle or container R. is first placed within the lower portion of the basin C, the rod 29 is in its lowered position with the cap 30 engaged over the upper end portion of the pipe 2| and with, of course, the enlargement of washer 3?. adjacent tothe lower end of said pipe 2|. The applied rod therefore closes the lower end of the pipe 2| against any matter entering the pipe when the receptacle is in its applied or working position. This is of advantage because upon the lifting of the rod 29 immediate equalizing of the air above and below the receptacle is assured, thus permitting the receptacle or container R to be lifted from within a basin C without suction resistance. To facilitate the removal or application of the rod 29 the cap 30 carries a clevis or looped head 33. The rod 29 may be lifted or removed by direct grasping by the hand or, if desired, a suitable instrument may be engaged with the clevis or looped head 33,
The recesses i9 and 2t also provide openings for the draining of water from within the receptacle or container R although to further facilitate such drainage the central portion of the bottom plate 1 is provided with a drain opening 3 3 and the upper portion of the receptacle is provided therearound in its wall I with the drain openings 35.
From the foregoing description it is thought to be obvious that a receptacle for a catch basin or the like constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be'understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
