Abstract

An operator protection device for use in connection with the operation of a sewer and/or catch basin cleaner containing a pressurized water hose, wherein the device comprises a first protective enclosure portion and a second enclosure member comprising a tubular sleeve of tough, flexible material slidably containing an exposed portion of the pressurized hose for protection of the lower extremities of an operator in the event of hose rupture or disconnection of a coupling member used to join sections of the pressurized water hose, and for ease in access and visiblity to the sewer and/or catch basin.

Claims

1. In a sewer and/or catch basin cleaner of the type including a water injection system comprising a high pressure water hose, reel means supporting said hose and arranged to permit the hose to extend into and be withdrawn from a sewer catch basin or manhole, means for delivering water under pressure through said hose and means for protecting an operator from water hose or hose coupling failure, said protecting means including:

a first hood-like shield portion at least partially surrounding an upper exposed section of the water hose adjacent said hose reel;

a second elongate tubular portion for enclosing said water hose extending between said shield portion and said sewer catch basin or manhole and having a free end extending toward and communicating with the opening of the catch basin or manhole, the combined length of said first and second portions providing head-to-toe protection of the operator in case of hose or hose coupling rupture.

2. The cleaner of claim 1, wherein said second portion includes a section thereof extending downwardly through the opening of the catch basin or manhole.

3. The cleaner of claim 1, wherein said hood-like shield portion has at least three adjoining sidewalls and an open bottom, said second portion having its end opposite from said free end extending inwardly of the open bottom of said shield portion.

4. The cleaner of claim 3, wherein said first shield portion is transparent.

5. The cleaner of claim 3, wherein said first shield portion contains integrally formed front and oppositely disposed sidewalls defining an open side facing said reel means and an open bottom spaced from and facing said catch basin or manhole.

6. The cleaner of claim 3 further including a housing for said water injection system, an access opening in said housing receiving said reel means, and wherein said shield portion is pivotally supported for storage within said access opening.

7. The cleaner of claim 6, wherein said first shield portion contains integrally formed front and oppositely disposed sidewalls defining an open side facing said access opening and an open bottom spaced from and facing said catch basin or manhole.

8. The cleaner of claim 6, wherein said first shield portion is transparent.

9. The cleaner of claim 6, wherein opposed stationary brackets are mounted at opposite sides of said access opening and wherein each bracket contains a camming slot configured to slidably receive a cam member extending from opposite sides of said first shield portion to slidably support and guide said first shield portion into and out of said access opening.

10. The cleaner of claim 1 further including level winding means for said hose comprising an operating arm extending outwardly from said cleaner and laterally movable within the spacial area defined by said first shield portion and said tubular portion extending downwardly from the distal end of said operating arm.

11. The cleaner of claim 10, wherein the distal end of said operator arm includes smooth surfaced guide means for guiding and protecting said water hose.

12. The cleaner of claim 10, wherein the distal end of said operator arm further includes at least one rotatably supported roller for guiding and protecting said water hose.

13. Operator protection means for a sewer and/or catch basin cleaner of the type including a pressurized fluid-containing hose supported by and extending from said cleaner and arranged to extend into the entrance of a sewer or catch basin, said protection means comprising:

(a) a first protective portion comprising a hood-like shield supported from said cleaner and spaced from the entrance of said sewer or catch basin, said shield surrounding an upper portion of said hose; and

(b) a second protective portion comprising a tubular sleeve surrounding said hose and having a sufficient length to extend from within said shield to said sewer or catch basin entrance;

whereby said portions cooperate to provide operator protection in the event of hose or coupling rupture.

14. The protection means of claim 13, wherein said tubular sleeve has a portion at one end extending inwardly of said shield and a portion at the opposite end extending downwardly through said sewer or catch basin entrance.
