CURB INLET

Ernest W. Shaw, Toledo, Ohio, assignor to The France Foundry &amp; Machine Co., Toledo, Ohio, a corporation of Ohio

Application June 6, 1938, Serial No. 212,106 (Cl. 182—6) therewith in lug 8 upstanding threaded portion or bolt 3 so that at seat 10 in the grating 7, nut I 1 may coact with this bolt 9 in anchoring this grating in position.

In carrying out the invention herein upon 5 pavement base 12 (Fig. 13), this primary frame 3 may be located. The running of pavement foundation as cement 13 is then effected continuously therealong and thereover, say as protected by cardboard sheet 14 (Fig. 15) in con- 10 junction with curb marking pavement limit form 15, which, as the pavement is run, may be taken up for the installation of curb, whether cast of concrete or trimmed stone curbing. In either event, as,the curbing form 15 is removed, supple- 15 mental frame having base flange 16 (Fig. 6) and upright brace portion 17 with upstanding supplemental frame 18 may be placed in position to have the base flange 16 register with the base flange I of the primary frame and this upright ₂0 portion 18 extend between the lugs of the U providing space from, open portion 4. This upright portion 18 is in the curb line thus ready to receive finish or trim 19 (Figs. 4,10) along the curb top with terminal depending portions 20 to ₂₅ride astride the upper portion of the free ends of the flange 3 and there be anchored in position by bolts 21 from openings 22 in the upright 18 and through openings 23 in the under side of the curb finish 19. There is accordingly left in reg- 30 ister position clearway or opening inlet 24 under this curb finish and laterally from the grating 7 as the major port for this waste water connection flow from the pavement surface as well as through the grating 7. _ 35

TticiO is economy in the installation hereunder for the reason that the primary frame may be set on the pavement base 12 and the run of pavement foundation 13 be continuous ovei this primary frame with the primary frame thereby 40 anchored with and as a unit of the pavement proper. This is simply effected in the type of concrete pavement wherein the foundation is the surface direct to the pavement face.

In other instances wherein on pavement base 45 12 there is laid foundation 25 (Fig. 14) in order that there may be finish surface whether of block or asphalt 26, it is in order hereunder similarly to place supporting flange I on the base 12. However, in lieu of the frame 3 there is minor frame 50 27 having inwardly extending lug or flange portion 28 with bolts 29 which may have nuts 30 to anchor sectional U-frame 31 as the carry-up portion from the pavement foundation 25 to position flush with the surface of the pavement 26. 55

Claims.

This invention relates to surface water disposal from pavements.

This invention has utility when incorporated in sewer waste intake assembly and connection 5 in the form of grating and curb inlet to the sewer or duct.

&lt; Referring to the drawings:

Fig. 1 is a plan view of an embodiment of the invention as the elements of a paving fixture;

Fig. 2 is a section on the line II—-II, Fig. 1, with the main frame and grating,, showing the curb section in elevation;

Fig. 3 is a side elevation of the grating;

Fig. 4 is an end elevation of the curb outlet 15 and finish portion;

Fig. 5 is a side elevation of the main frame;

Fig. 6 is an end elevation of the supplemental frame adapted to fit with the main frame, these Figs. 3, 4, 5 and 6 being in distributed grouping;

Fig. 7 is a fragmentary plan view of a portion of the main frame of Fig. 5;

Fig. 8 is a fragmentary view in plan of a portion of the supplemental or curb frame of Fig. 6;

Fig 9 is a section on the line IX—IX, Fig. 7, 25 showing assembly of the grating with the main f Γ21Π16 *

Fig. 10 is a fragmentary front elevation of the curb finish;

: Fig. 11 is an elevation of the front or cross 30 portion of the sectional frame to be mounted on the primary frame in carrying up from pavement foundation to pavement height;

Fig. 12 is a fragmentary plan view of the sectional u-frame of Fig. 11;

Fig. 13 is a view, with parts broken away, of the foundation frame installed in the pavement for finish flush with the pavement;

Fig 14 is a view similar to Fig. 13, of the foundation frame installed in a pavement wherein 40 there is supplemental surfacing and extension of the frame from the frame base or major sec_: tion; and , . .,

Fig. 15 is a fragmentary plan view, wherein the fixture may be as to the main frame installed 45 with curb continuity line running therepast and the curb portion of the frame to be later or subsequently installed. .

Partially circular lower base flange 1 (Fig. 1) has uprising brace flanges 2 therefrom to three50 sided frame portion 3 forming U with open side 4 (Fig. 5). This U-shaped main frame portion 3 on the inner side is inwardly extending flange 5 (Fig. 7) upon which may rest bounding flange 5 of grating 7. In the forming of this primary 55 frame, say of cast iron, there may be anchored

2,159,752

These bolts 29 may be inserted in the primary frame and held in position by the concrete so that the U-section 31 may be anchored therewith.

In the layout wherein the pavement founda_g tion 25 falls short of the extent of the finished pavement surface, the clearway in the U-frame is not placed with a grating but with an insert strip or plate, say of sheet metal, on the lower ledge to bring to flush position in order that ₁₀ pavement continuity may be thereacross. Upon locating then placing U-frame 31 as a section to complete the primary frame, the grating may be installed as normally thereon and this followed with the curbing section in the sequence after the pavement foundation which has effected the anchoring of the primary frame.

While the pavement base 12 may be continued under the curb line or form 15 in thereby providing support for the supplemental frame base _2Q flange 16, there is preferred additionally effecting an interlock between this primary frame having the base I and this supplemental frame having the base 16, which interlock is herein shown as projecting lug 32 (Fig. 6) having slot 33 in pro25 viding a fork, one at the inside of each of the legs of the U-frame 3. When so brought into position as to the bolt holes 34 in the frame 3, locking may be effected between these fork ex tensions 32 and the frame 3 by bolts 35. These bolts 35 are anchored in the cement for the application of the nuts thereto after the placing of this supplemental curb section.
