EDWARD C. BROWN, OF CHICAGO, ILLNOIS.

` CATCH-BASIN.

Application filed January 15, 1913.

To all 'LU/0m may concern.'

Be it known that l, EDWARD C. BROWN, a citizen of the United States, residing at Chicago, .in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Catch-Basins, of which the following is a specification.

rlhis invention relates to catch basins for sewer systems, and further pertains to an improved trap for such catch basins.

One of the objects of the invention is to provide an improved trap comprising a portion which is readily removable and replaceable so that access to the outlet from the Vcatch basin may be conveniently had when desired.

Another object is to provide an improved trap which may be built as a complete article of manufacture ready to be installed in a catch basin.

A further object is to provide a combined trap and building block, the latter' being adapted to be built into the wall of the catch basin.

My invention also pertains to an improved manner of constructing catch basins to gradually taper the upper ends thereof down to a smaller diameter.

The invention further refers to an improved shape and arrangement of the blocks from which the basin is constructed, and the relation of the inlet and outlet pipes thereto.

The invention also relates to the other features and advantages hereinafter more fully pointed out.

ln the accompanying drawings, Figure il is a vertical central section through a catch basin embodying the features of my invention, the view being taken in the plane of line a a in Fig. 2. Fig. 2 is a horizontal section in the plane of line b Z) of Fig. 1, the arch 15 being shown in plan. Fig. 3 is a detail perspective view of the trap.

In the drawings, the catch basin is shown circular in shape, being built up of a plura1- ity of superposed courses 5 each comprising a set of blocks 6. These blocks may be of concrete, tiling, or other suitable material. lWhen the basin is made circular, the blocks are preferably of arcuate shape, as shown in' Fig. 2, the. abutting ends of the blocks having a ribandgroove interlocking connection. Preferably, the catch basin is tapered olf at its upper end, and this may be conveniently done by omitting from the top courses a successively greater number of Specification of Letters Patent.

blocks in the process of construction. As shown in Fig. 2, the courses of the body portion each consist in this instance of seven blocks. ln the course 5a, one block is omitted, which makes the course of slightly less diameter. In the next course 5" above, two blocks are omitted, leaving tive blocks in the course, and making the course of still less dian'leter. The top ring 5 is preferably made in an integral piece.

7 indicates the cover for the manhole which tits in an annular seat in the top of the top ring 5a.

The inlet to the catch basin is indicated by the numeral. S, and the outlet by 9. rllhe inlet opening is formed by providing complementary7 recesses in the blocks of two adjacent courses. In the present instance, the block in the lower course has a semi-circular recess in its upper face and the two blocks overhanging said block have segmental recesses in their adjacent .lower corners. These recesses form the circular opening in which the inlet pipe lits.

In its preferred form, the stationary portion of my improved t 1ap is built integral with a block l() which is substantially similar in shape to any of the other blocks of the catch basin. This combined block and trap is preferably formed of concrete. ln its upper face, the block has a semi-circular recess ll adapted to receive the lower half of the outlet pipe i), and the blocks next above the block l0 are recessed to receive the upper half of the outlet pipe, as above de scribed in connection with the inlet pipe. The block l0 has a groove l2 in one end, and a rib 13 on the other end to interlock with corresponding parts on the adjacent blocks. rlhe stationary portion of the trap consists of a substantially vertical arcuate wall la having its ends integral with the inner side of the block. Preferably, the lower edge of the wall 14; is in approximately the same plane as the lower edge of the block. At any rate, the lower edge of said wall should be in a lower plane than the bottom of the recess l1 or the interior of the outlet pipe 9.

An arch or cover l5 is adapted to lit upon the upper edge of the vertical wall ll, said arch having an arcuate riib 16 at its lower edge arrange-d to lie inside of the upper edge of the wall la. rlhe arch further has a curved rear face 17 adapted to fit against the concave inner face of the block which lies immediately above the block l0. Thus the arch l5 constitutes a top wall or closure for the upper end of the trap.

The inlet 8 to the catch basin will be placed in a plane above the outlet 9. As the fluid enters the catch basin from the inlet, the solid material in the fluid will settle to the bottom in the usual way. `When the level of the liquid rises to the height of the outlet pipe, the liquid will flow ed therethrough, but 'the trap will serve to prevent a direct current between the inlet and the outlet in a manner well known.

ln case the outlet should become clogged, it is necessary only to lift 0E the top wall or arch 15 of the trap, when a ram or plunger, commonly used for the purpose, may be conveniently inserted into the outlet pipe and the latter cleaned out. lllhen this operation is finished, the arch is replaced.

t will be seen that I have provided a very simple and convenient trap through which access may be conveniently had to the outlet from the catch basin. The trap is strong and durable and may be cheaply constructed.

l realize that various changes from the embodiment herein shown may be made without departing from the spirit of the invention and the scope of the appended claims, wherefore l do not limit myself to the eXact construction disclosed.

I claim as my invention:

l. A. catch basin having an outlet, a substantially vertical wall of arcuate form having its ends secured to the wall of the catch basin, the lower edge of said wall lying in a plane beneath said outlet, and a top portion of arch shape seated on the upper edge of said wall and having an interlocking connection therewith, said arch portion having its rear side shaped to engage the wall of the catch basin at the upper side of said outlet.

2. As a new article of manufacture, a solid block adapted to be built in the wall of a catch basin and a trap comprising a portion formed integral with said block, and another portion removably mounted on the first-mentioned portion.

3. As a new article of manufacture, a block adapted to be built into the wall of a catch basin and having a recess adapted to receive an outlet pipe for the catch basin,

an arcuate wall built integral with the i11- ner side of said block, the lower edge of the wall lying in a plane beneath said recess, and a removable section seated on the upper part of said wall.

el. As a new article of manufacture, a block adapted to be built into the wall of a catch basin, said block having a groove in one end, a rib on the other end, and a semi-circular recess in its upper side adapted to receive an outlet pipe for the catch basin, and a trap comprising arstationary portion formed integral with said block and a portion removably mounted on said stationary portion.

5. As a new article of manufacture, a block adapted to be built into the wall of a catch basin, an approximately vertical arcuate wall integral with the inner side of said block, and an arch portion seated on the upper edge of said wall and having an interlocking connection therewith.

6. As a new article of manufacture, a

block adapted to be built into and form a l catch basin, a substantially vertical arcuate wall having its ends integral with the inner side of said block, and an arch shape member seated on the upper edge of said wall and having an interlocking connection therewith, the top of the arch being so positioned as to lie above an outlet pipe seated in said recess.

8. As a new article of manufacture, a block and an arcuate wall having its ends abutting against one side of the block. the A block and the wall being integral, and a removable section mounted on said arcuate wall.

n testimony whereof l my signature in the presence of two witnesses.
