Description
2()07415 PIVOTABLE TRAP APPARATUS FOR DRAINAGE PIPES
This invention relates to apparatus for the inlet ends of drainage pipes leading from enclosures such as street catch basins, spetic tanks and the like.
A trap apparatus for drainage pipes is disclosed in Canadian Patent Serial No. 717,806 which is issued to the applicant on September 14, 1g65.
This trap apparatus is comprised of a substan-tially horizontal sleeve adapted to fit in the inlet end of drainage pipe extending from a sidewall of a water holding enclosure. This sleeve has an inner end pro-jecting into the enclosure. A hood is connected to the sleeve and encloses the sleeve's inner end. This hood extends downwardly to a level below the sleeve and the inlet end of the drainage pipe and has an entrance at this level. Water can thereby flow through the hood entrance and out of the enclosure to the drainage pipe while debri~ floating on the water is kept by the hood from reaching the drainage pipe.
In order to prevent the trap apparatus from being vibrated out of the drainage pipe, the sleeve was given some resiliency to cause the sleeve to bind in the drainage pipe and therefore make it more difficult to remove the apparatus from the pipe. Accordingly, if ;~00741S
:
access to the drainage pipe was required, removal of the apparatus would tend to be difficult since it was necessary to contract the sleeve in a radial direction and then to pull it straight out from the pipe.
In addition, in some instances the drainage pipe extends away from the basin at a lateral angle relative to the wall of the catch basin or downwardly therefrom.
In order to fit the trap apparatus properly, a series of score lines were provided to permit pieces of material defined by these score lines to be removed from the side walls of the trap apparatus. This would permit the trap apparatus to bear against the wall of the catch basin with the sleeve inclined downwardly in the pipe. This is fairly awkward since the user has to manually cut these pieceis of material before installation and thereby increases the installation time and also increases the likelihood of injury since sharp edges are created around the hood. This also increased the likeli~ood of knowing the trap apparatus improperly installed.
There is therefore a requirement for an improved trap apparatus for drainage pipes able to provide access to the drainage pipe as well as permit an easy and simple way of adjusting the trap apparatus against the catch basin wall when a downwardly inclined drainage pipe is used.
It is therefore an object of the present inven--2~
~0074i5 tion to provide an improved trap apparatus which provides means for accessing the drainage pipe of a catch basin.
Another object of the present invention is to provide an improved trap apparatus having a hood and sleeve which are pivotable relative to one another such that the trap apparatus can be adjusted to fit against the wall of the catch basin in instances where the drainage pipe extends away from the catch basin at lateral angles relative to the catch basin.
Accordingly, an aspect of the present invention -is to provide an improved trap apparatus for the inlet end of a drainage pipe leading from a side wall of an enclosure adapted to hold a body of water which runs through said pipe, said trap having a sleeve adapted to fit in the inlet end of a drainage pipe extending from a side wall of a water holding enclosure, the improvement comprising:
a hood slideably and pivotably mounted to the sleeve, said hood extending downwardly to a level below the sleeve and said inlet end of the drainage pipe and having an entrance at said level, said hood having means for accessing said drainage pipe and wherein said hood can be slided and tilted away from said sleeve to be positioned adjacent said side wall.
Particular embodiments of the invention will be understood in conjunction with the accompanying drawings ' r ; ' "' ' ~
~007415 , .
in which:
Figure 1 is a side view of the improved trap apparatus as secured to a side wall of a catch basin;
Figure 2 is a front view thereof;
Figure 3 is an exploded view of the improved catch basin apparatus.
Referring to Figure 1, we have shown the improved trap apparatus 10 mounted on a side wall 11 of a catch basin. In this embodiment the drainage pipe 13 is basically horizontal and the side wall 11 of the catch basin lies perpendicular to the drainage pipe.
Referring now to Figures 1, 2 and 3, the improved trap appartus is comprised of a radially expan-sible sleeve 12 which is adapted to be contracted and inserted into the inlet end of the drainage pipe 13. In the preferred form of the invention, the sleeve is formed of a springy metal, such as aluminum galvanized iron, or a suitable plastic material, and is made expandable by a slit 14 which extends longitudinally thereof. The slit of the sleeve makes it possible to squeeze the sleeve down to a diameter less than its normal diameter so that it can easily be inserted into pipe 13. When th~ sleeve is released, its springs back towards its normal size, at which time it snugly fits into the pipe, as clearly shown in Figure 1.
A pair of hood supports 15 are connected to the ,: :, " " , : - .
.: : : - .,, , :
,,.. ,,: ,, , , ~ :
, Z00741s inner end 16 of the sleeve. The hood supports 15 are spot welded at 17 to the inner end oP the sleeve 12.
Hood supports 15 also include channels 18 along which can slide a carrying bolt and wing nut arrangement 19 which is also inserted through a vertical channel 20 on side wall 22 of hood 21.
In order to mount trap apparatus 10 onto wall 11, sleeve 12 is pulled apart from hood 21 as depicted by the phantom lines. Sleeve 12 is then compressed to reduce the diameter thereof and then inserted into pipe 13 and released. Sleeve 12 will tend to spring back to its normal size and thereby engages the inner surface of pipe 13 and firmly hold the apparatus then in position.
Hood 21 is then adjusted such that the side edges 23 bears evenly against the side wall 11 of the catch basin.
Wlng nuts 19 are then rotated to secure hood 21 in posi~
tion.
Accordingly, trap apparatus 10 can be adjusted to any variation of inclination that drainage pipe 13 can have with respect to the side wall 11 of the catch basin.
In Figure 1, an inclined drainage pipe has been shown in phantom lines. Hood 21 as shown in Figure 1 include means for accessing the drainage pipe without having to remove the trap apparatus from the side wall of the catch basin. More specifically, a rear excess plate 24 is pivotably mounted about a rivet point 25 and held ;~007415 against an L-shaped clamp 26. A rear support plate 27 is riveted to side walls 22 of hood 21 ~y means of a series of rivets 28. Rear access plat~ 24 can be pivoted about rivet point 25 as is shown by the phantom lines.
Rear access plate 24 can be pivoted by means of a cable lowered into the catch basin, the cable being maneuvered to fit under hook 29 of rear access plate 24.

Accordingly, an aspect of the present invention -is to provide an improved trap apparatus for the inlet end of a drainage pipe leading from a side wall of an enclosure adapted to hold a body of water which runs through said pipe, said trap having a sleeve adapted to fit in the inlet end of a drainage pipe extending from a side wall of a water holding enclosure, the improvement comprising:

tion.
Accordingly, trap apparatus 10 can be adjusted to any variation of inclination that drainage pipe 13 can have with respect to the side wall 11 of the catch basin.
In Figure 1, an inclined drainage pipe has been shown in phantom lines. Hood 21 as shown in Figure 1 include means for accessing the drainage pipe without having to remove the trap apparatus from the side wall of the catch basin. More specifically, a rear excess plate 24 is pivotably mounted about a rivet point 25 and held ;~007415 against an L-shaped clamp 26.
