Abstract
ABSTRACT OF THE DISCLOSURE
A culvert end guard for preventing the clogging of a culvert pipe by beavers includes a skeletal frame for mounting on the open end of the culvert; a gate defined by a plurality of parallel crossbars normally resting on the open, inclined outer end of the frame and a first chain interconnecting the crossbars and pivotal connecting the gate to the frame; and a second chain connected to the first chain for rotating the gate to the open position. In use, the gate catches debris while permitting the passage of water. Periodically, the gate is moved to the open position by pulling on the second chain either manually or by attaching it to a vehicle, with the effect of removing debris. The gate is again closed for re-use.

Description
~3476~
This invention relates to a culvert guard, and in particular to a culvert end guard for preventing the plugging of culverts.
Each year in North America, various levels of governments and private concerns spend large sums of money repairing roads damaged or washed out because of blocked culverts. Rather than building a dam in a wide stretch of stream, weavers commonly plug ; culverts with sticks and other debris to abbreviate the dam building process. In order to avoid this problem, one solution is to block the ends, or at least the upstream end of the culvert.
Culvert gratings or guards are disclosed, or example by Canadian Patent No. 292,599, issued to WOE. Babe on August 27, 1929, and United States Patents Nos. 3,472,030, issued to RYE.
Wreck on October 14, 1969 and 3,587,239, issued to OWE Eland on June 28/ 1971. The patented structures are intended as more or less permanent fixtures, without sell contained cleaning mechanisms and therefore are difficult to clean.
The object of the present invention is to overcome the problem of beaver blocked culverts by providing a relatively simple culvert end guard, which is easy to clean and maintain.
Accordingly, the present invention relates to a culvert end guard for preventing the clogging of the open end of a culvert pipe comprising skeletal gate means for pivotal mounting on said culvert pipe for normally closing said open end, said gate means permitting the passage of water while impeding the passage of I
~;~3~76~
debris into the culvert and chain means for rotating said gate means to an open position for cleaning.
The invention will now be described with reference to the accompanying drawings, which illustrate a preferred embodiment of the invention, and wherein:
Figure 1 is a perspective view from one end and above of a culvert end guard in accordance with the present invention;
Figure 2 is a rear end view of the guard of Fig. l;
Figure 3 is a front end view of the guard of Fig. l;
lo Figure 4 is a perspective view of one end of a culvert and a second embodiment of the culvert end guard ox the present invention;
Figure 5 is a perspective view of a third embodiment of the culvert end guard of the present invention.
Figure 6 is a plan view of another embodiment of the culvert end guard of the present invention;
Figure 7 is a side view of the culvert end guard of Fig.
6; and Figure 8 is a front end view of the culvert end guard of Figs. 6 and 7.
With reference to the drawings, one form of culvert guard in accordance with the present invention includes a skeletal frame generally indicated at l. The frame l is defined by a rectangular base 2, triangular sides 3 and an open, generally rectangular rear end 4, with a semicircular top end 5.
~;~3~76~
The base 2 is formed by steel rods, which are welded together to define a pair of sides 6. The sides 6 are inter connected by a plurality of parallel, spaced apart crossbars 8.
The triangular sides 3 are defined by parallel, vertical, spaced apart rods 9 and inclined top bars 10. The top ends of the inclined bars 10 are interconnected by a crossbar 11. A second, reinforcing crossbar 13 extends between the rear most side rods 9 of the frame sides 3. The crossbar 13 limits movement of the frame 1 towards the open end of the culvert (not shown) The rear end 4 of the guard is defined by a pair of arcuate rods 15, which are connected to the sides 3 of the frame.
Plates 16 interconnect the sides and top of the rods 15. Holes 17 are provided in the plates 16 for connecting the frame 1 to the open end of the culvert.
A gate 20, which includes a plurality of parallel rods 21 and chains 22 and 23 is pivotal mounted on the open top front end of the frame 1. The ends 24 of the rods 21 are bent downwardly to make it difficult for a beaver to move the rods out ox position. The ends of one chain 22 are connected to spaced apart eyes 25 on the crossbar 11. The chain 22 is connected at two locations to each gate bar 21 near the ends thereof, and forms a loop 26 beyond the front end ox the gate. The chain 23 is connected to the front center of the loop 26, and a hook 28 is provided on the outer end thereof.
In use, the rear end 5 of the frame 1 is connected to ~23~76~
the open end of a culvert. With the gate 20 in the closed position, the device prevents the clogging of the culvert with debris. The debris is caught on the gate 20. Debris must periodically be removed prom the gate 20. It is merely necessary to manually pull the gate to the open position, or to attach the hoot 28 to a vehicle hitch or the like and drive away from the rear end of the frame l. The gate 20 will follow to dislodge debris therefrom. The gate can again be closed for continued us.
A second embodiment of the invention (Fig. 43 is lo virtually identical to the first embodiment, except that the frame 1 and gate 20 taper forwardly. Thus, less material is required to construct the guard. A socket 30 is mounted on the top rear of the frame 1 for receiving a flag 31, which makes it easier to locate the guard. Ox course, a slag can be provided on all embodiments of the invention. The guard of Fig. 4, like the guard of Figs. l to 3, is intended for use on the open end of a cylindrical culvert pipe 32.
With reference to Fig. 5, a third embodiment of the invention which is intended for use with a culvert pipe 34 having an inclined end includes an elliptical frame 35, which is mounted on the inclined open end of the culvert pipe 34. gate 37 defined by parallel, spaced apart crossbars 38 and a chain 40 connected to each crossbar 38 is pivotal mounted on the frame 35. The ends of the chain 40 are connected to a plate 41 on the top of the frame 35 above the open end of the pipe 34. A second chain 43 ~;~34'766 and a hook 44 are connected to the bottom front end of the chain 40 for opening the gate.
A fourth embodiment of the invention (Figs. 6 to 8) intended for use with a culvert pipe 46 having an inclined end 47 includes a frame, the bottom portion ox which is defined by three elliptical hers 49, which are interconnected by rods 50 and plates 51. Pins or bolts 53 extend through the plates 51 to secure the frame to the culvert end. The frame is completed by a rectangular gate support 54, which is connected to the upper-most bar 49 by a plurality of rods 56.
A gate defined by a plurality of crossbars 57 and a Sheehan is mounted on the support 54 or closing the open top end of the frame. The chain 58 is connected to each of the crossbars 57, and the ends of the chain are connected to loops 60 at the top end 61 of the support 54. A second chain 63 and a hook 64 are connected to the bottom front end of the chain 58 for opening the gate.
It will be appreciated that in its simplest form, the culvert end guard includes a skeletal gate for pivotal mounting on the open end of a culvert, and the chain(s) for moving the gate between the closed and open positions.
