No. 890,573w PATENTED JUNE 9, 1908. J. M. PHBLAN.




Patented June 9, 1908.

Application filed March 6, 1906. Serial No. 304.582.

To all whom it may concern:

Be it known that I, Joan MPHELAN, a citizen of the United States, residing at Jack son, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Reinforced (emcnt or (oncrcte (latch-Basins and Sewer-Pipe, of which the following is a specification.

The objcct of my present invention is to provide a catcli'basin and a sewer )ipc which will be reinforced both transversely. and iongitudinally thereby providing an exceedingly strong and durable article.

Another object of the invention is to provide 'a catch basin which in addition to being reinf orccd. will be provided with castings carrying steps which can be pushed in or out as desired, and which when pulled out will serve as a ladder by means of which descent into and ascent from the catch basin can be conveniently had. 4

With these ob'ects in view m invention consists in providing longitudinal and transverse reinforcing strips or. bands which are embedded in the cement or concrete when the catch basin or pipe is formed, and the invention consists also in the employment of castings which are also embedded in the ocment or concrete of the catch basin and which have the steps or'ladder rungs connected thereto, said steps or rungs being adapted to be pulled out or pushed in as desired.

The invention also consists in certain de tails of construction hereinafter fully de scribed and pointed out in the claims.

In thedrawings forming a part of this speeilicationz-Figure l is a vertical sectional view of a catch basin constructed in accordance with my rinvention. Fig. 2 is a transverse sectional view taken on line 22 of Fig. 1. Fig. 3 is a detail perspective view'' of one of the longitudinal reinforcing bantls or strips. Fig. 4 is a detail sectional view of the castin with the adjustable step or run" arranged fiiercin. Fig. 5 is a detail sections view of the said casting the ste or run r being removed. Fi 6 is a detail view 0 the rung or stc detae ed from the casting, and Figs. 7 am 8 are detail views of the reinforcing strips or bands employed in connection with a cement or concrete sewer pipe.

Referring to the drawings A indicates a cement or concrete out ch basin which maybe any size desired and may be made with a conical or dome. shaped contracted top as preferred. 'lhis catch basin, it will be understood, is made in a mold or form especially adapted for the purpose and for the purpose of reinforcing said catch basin, I arrange a plurality of metallic reinforcing strips B bent at an angle as'shown at B at its lower end and also bent at nn'angle at its upper end as shown at B 'lhcse metallic strips B have one or more straps punched therefrom at intervals for the purpose of receiving and holding the transverse or circumferential re inforcing bands I), which are )assed through the loops produced by puncliing the strap portion outwardly and )y arranging the're- PATENT-OFFICE.

inforcing strips and bands in the'mold before the cement or concrete is poured in, and it will be seen that a metallic skeleton frame is rovided around which the catch basin is ormed and which is securely embedded in the walls and bottom of the cat-ch basin and constitulcs a reinforcing frame. ln lfigs. 7 and 8 l have shown two forms of reinforcing strips which can be used in making cement sewer pipes, the form shown in Fig. 7 being a flat twisted strip and the form shown in Fig. 8 being a flat strip provided with offset portions. Both forms serve to prevent the reinforcing strips pulling out or working loose.

in addition to providing the catch basin with reinforcing metallic frame work, 1 arrange a series of castings preferably u on opposite sides and arrange them so that t on extreme inner ends are flush with the inner walls of the catch basin. The castin s E com rises the hollow end portions E anfi the soliifconnccting bar E the inner ends of "the hollpw portions being contracted as shown llrlu 1.

. 1 indicates the step or ladder rung curved to conform to the curve of the catch basinand having its ends F bent and adapted to slide inthe hollow portions E of the castings E, and in order to prevent the step or rung bein completely withdrawn from the eastpreferably pass a cross pin F through the ends as shown which cross pin will prevent the' said step or rung being pulled out after the casting with the etc or rung has once been inserted in the-'wal of the asin. Instead of passin a cross in the extreme end of the member 1+ may be out over and serve the same iurpose.

From t c foregoing description taken inconnection with the accom enying drawing, it will be seen that l provir e an exceedingly strong and durable catch basin thoroughly reinforced throughout, and also that I provide a, ladder upon he interior of the catch basin the steps rungs of which can be pushed in when not desired for use and pulled out ready for use whenever desired. it will he understood, of course, that manholes and other openings can be prmridcd any point desired. it is also obvious {hut the rein lorcing principle herein set lorh can be applied to cement or concrete sewer pipes.

Having thus fully described my invention, whetvl claim as new and desire in secure by Letters Patent, isz--- i. The combination with a; cement or con- (Tetl catch basin, of a, plurality of costings embedded the side wall of the said catch basin, the and portions of said castings being hollow, and the steps shaied as described and having their ends slidohlyinountod in the hollow portion of the costings as set forth.

seams 2. A cement or concrete cylindrical body provided with a lurality of castings embedded in its wal s, each casting having a hollow end portion and a solid connecting her, the inner ends of the hollow end portions being contracted, the steps. or rungs having their ends bent and inserted in the hollow end portions of the castings, and means to prevent the withdrawal of the said bent ends I from the castings.

3. The'combination with a cement or concrcte cylindrical body, of the metallic steps having end portions, and the intermediate curved portion, the curved portions of said step corresponding with the curve of the cylindrical bod and the castings inserted in the sides of t e cylindrical body and in which the end portion of the steps are slidably mounted, asset forth.
