CATCH-BASIN.

SPECIFICATION forming' part ofy Letters Patent No. 642,530, dated January 30, 1900. Application tiled September 20, 1898. Serial No. 691,474. (No model.)

To all whom it may concern,.-

Be it known that I, GEORGE A. ROBERTSON, a subject of Her Majesty the Queen of Great Britain, residing at Vestmount, Province of Quebec, Canada, have 'invented certain new and useful Improvements in Catch-Basins, (for which Letters Patent of the Dominion of Canada were granted September 6, 1898,No. 61,106, the application for which was led August 26, 1898, Serial No. 82,826;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in street-receivers or catch-basins, and has\par ticular reference to that type of catch-basins which are made of aplurality of sections; and my object, brieiy stated, is to provide catchbasins of this type which are particularly adapted for use in cold climates, where the sewer-pipes are at a suitable depth, so as to,

be below the frost-line and where the catchbasins must necessarily be quite deep.

All sectional catch-basins for sewers as heretofore constructed, so far as I am aware, have been formed so that movements of the earth around them, due to the action of frost, has had a tendency to separate the sections and to loosen the connection with the sewerpipe. It has been proposed in such catchbasins to provide interlocking lugs on such sections; but this adds expense to the catchbasin, and, moreover, the interlocking lugs are liable to become broken. There are several advantages in sectional catch basins which make them desirable. Among these advantages are: They are easier to construct in sections and are easier transported when so made. If a breakage occurs in a section the entire catch-basin is not ruined. In locating such catch-basins the lower section can be placed at the `bottom of the excavation and the connection with the sewer-pipe made while the workman stands inside of said lower section, after which the upper sections can be placed in position. The'earth around the lower part of the catch-basin vcan be stamped down in place better and more solidly when the catch-basin is a sectional one than when in one whole piece, because it can be done before the upper sections are put in place, the workman standing inside the lower section, and the excavation for a sectional catch-basin does not have to be as large as for an integral catch-basin of the same size, for the reason that, as above stated, the operation of making the connection with the sewer-pipe may be performed while the workman stands inside and reaching over with his arms, while with an integral catch-basin the excavation must be large enough to permit the workman to stand and work outside thereof in making such connection. Another important advantage in a sectional catch-basin is that when the grading vof the street is changed the upper section may be removed and may be replaced by another section of greater or less height, as 1 occasion may require, whereas when an integral catch-basin is used it frequently has to be entirelyremoved and replaced by another or has to be reset. As above stated, however, so far as I am aware,all sectional catch-basins for sewers have been so constructed that they were liable to be acted upon by the movements ot earth around them to the detriment of the connections between the sections and with the sewerpipe.

The object of my invention lis to provide a sectional catch-basin for sewers that will be free from any external projections that might be acted upon by the earth and ,of such form that no lugs or interlocking parts are necessary to insure the correct and permanent relative positions of the various sections. I attain these Objects by constructing the catchbasin of a series of uniformly-tapered sections, each section being larger at the bottom than at the top, the lower section having means for connecting it with a sewer-pipe and having a closed bottom of greater diameter than any other portion of the catch-basin, the upper sections being entirely free from external projections.

In the drawings, in which similar numerals of reference indicate similar parts in all of the views, Figure 1 is a view showing my invention as applied. Fig. 2 is a central vertical sectional view of the same. Fig. 3 is a top plan view of the trap. Fig. 4 is an elevation of the trap.

1 designates a catch-basin formed of a series of sections 2, the lower section being pro- ICO vided with a bottom which may be formed integral with the sides of the section or may be secured thereto to make a perfectly tight joint. The lower section is provided at one side with an opening 3, to which is applied the sewer-pipe connection t, and mounted inside of said opening 3 a trap 5 is removably secured in a suitable manner, such as bysuitable inclined slideways 6, in which thetrap 5 is adapted to be placed and be heldin tight position by reason of its weight, a removable top 7 serving to close the top of the trap in 'an obvious man ner. Each of the sections exclusive of the lower section is provided at its lower end with inwardly-extending annular flanges 8, which are adapted to fit on the upper end of the next section below. The upper section has a portion of its top closed,

as best shown in Fig. 2, and within the re.

duced opening formed and mounted on the top of the upper section is the street or top section 9, having its face provided with suitable openings 10 for the passage of the drainings. If desired, the top of the section 9 may be made removable, although such is not necessary.

By this construction it will be readily seen that I have provided an improved catchbasin which is extremely durable in its construction and which when the grade of the street is to be changed will allow of the varying of the position of the basin without unnecessary trouble, this being accomplished by means of the addition to the basin of another section or the substitution of sections of different sizes, it being apparent that sections of various sizes may be made as may be found necessary and that one may be readily substituted for another.

It will now be understood that, due to the shape of the basin, any pressure of the earth against the sides will only tend to more firmly hold the upper sections upon the lower one, which latter is in practice firmly seated below the frost-line, and this is attained without the use of any locking means whatever between the sections, and owing to the fact that no interlocking devices are employed no particular care is necessary when locating the upper sections, as each said section may be simply placed in position and left there Without rotating or using any care or effort to make the parts fit, as is necessary where interlocking lugs are used. This freedom from interlocking lugs or projections enables the section below the section 9, however, to be so rotated, if necessary, on its seat as to bring the top of that section in proper position to receive said section 9, so that the face of said latter section will be held in aline; ment with the curb or other predetermined position, as will be clear by referring to igs. 1 and 2.

Having thus described my invention,what I claim as new is- A catch-basin comprising a series of uniformly-tapered sections, each section being larger at the bottom than at the top, the lower section having a sewerpipe connection and a closed bottom of greater diameter than any other portion of the catch-basin, the upper sections being entirely free from external projections and each of the upper sections being freely rotatable upon the section below it, each section except the lower one having an annular flange fitting within the upper edge of the section on which it rests, whereby the upper sections are solely and firmly held to their seats by the pressure of the earth against their tapering sides, and whereby the shape and external configuration of the catchbasin as a whole will prevent any portion thereof from being lifted by movement of the earth against the sides of any portion thereof, the upper end of the upper section having a non-circular opening, and a street or inlet section fitted to said opening, whereby said street or inlet section can be rotated only with the upper tapering section.

In witness whereof I have hereunto set my hand in the presence o f two witnesses.
