Tool Holder Clamp for Suction Hose

Abstract

A tool holder clamp fits over the suction hose or intake nozzle of a vacuum pumper truck. The clamp takes the form of two or more C-shaped sections that can bolt together over the hose, with each C-shaped section having one or more through bores serving as sockets for holding a tool such as a flashlight or the head or nozzle of a jet hose. The sockets have associated slots to permit the socket to be snugged down against the tool.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

[0024] With reference to the Drawing Figures, FIGS. 1 and 2 illustrate a typical implementation of the suction hose clamp holder according to the principles of this invention. In a sanitary waste tank situation, a suction hose or vacuum hose 10 would extend from pumper truck (not shown here) and into a customer's septic tank so that the liquid waste in the septic tank can be pumped through the suction hose 10 into the truck's vacuum tank. While the septic tank may be partly above ground, it is understood that typically the septic tank extends down a significant distance below the surface. In order for the operator to see into the septic tank and guide the intake nozzle of the suction hose, it is useful to employ a torch or flashlight that is aimed in the axial direction of the intake nozzle. At the current time, the operator has to hold the torch or flashlight in one hand and guide the suction hose with the other hand, or else the operator needs to enlist a helper to shine the light into the septic tank through the opening in the top of the septic tank. Neither technique has been particularly convenient or effective. It takes about an hour to remove the liquid from a typical septic tank in this way, which then requires the operator or helper to hold the flashlight or torch for an hour. Ideally, the light should be mounted onto the hose or onto the intake nozzle, but no practical arrangement to accomplish this has existed previously.

[0025] This process can be complicated if blockages occur within the septic tank, which normally requires the operator to clean them away using a jetter hose to direct a high pressure spray at the solid material. This is difficult and time consuming if the operator is required by himself both to suck out the liquid from the septic tank and also operate the jetter hose.

[0026] In the embodiment shown here a clamp ring 12 has two main components that are fastened together onto the suction hose 10 or onto the generally cylindrical intake nozzle, and here is shown carrying a number tools 14 of generally cylindrical shape, i.e., in this case four (4) flashlights oriented so their beams are directed in the distal direction and parallel with the axis of the tubular suction hose and intake nozzle.

[0027] The clamp ring has two half ring components 16, which favorably are of identical shape, and positioned so as to connect the ends of each to corresponding ends of the other.

[0028] As shown favorably in FIGS. 3A to 3D, each half-ring 16 has an inside semi-cylindrical surface 18 that is positioned against the surface of the hose 10 (or nozzle), and there are a pair of generally cylindrical tool sockets 20 that penetrate through in an axial direction, each socket 20 having a diameter of a nominal 1 inches so as to match the size of the flashlight or other tool to be held there. Connected to each socket 20 there is an associated slot 22, also open through in the axial direction, so as to define a tongue 24 between the outside of the half ring and the slot 22. The tongue is free at the end remote from the socket 20. A respective bolt hole 26 extends in a radial direction through the tongue 24 and then across the slot into a remaining arcuate band 28 at the radial inward part of the half ring 16. The part of the bolt hole 16 in the band 28 may be threaded so that a suitable threaded bolt can be used to draw the tongue 24 radially inward and squeeze the respective socket 20 against the flashlight or other tool being held in the socket.

[0029] Each end of the half-ring 16 is a flat end surface 30 oriented to face a corresponding end surface 30 of the other half-ring 16. Favorably, at one end or at both ends there can be an access cut-out 32 of arcuate profile and ending above the end surface to define a flat flange 34, with a bolt hole centered in the flange 32. If the access cut out 32 and flange 34 are formed on both sides, the two half-rings 16 can be joined by a pair of bolts 40 with the head of the bolt fitting into one or the other cut out 32 and with a nut (not shown) in the cut out 32 on the opposite half-ring 16. Where the access cut out 32 and flat flange 34 are provided at one end only of the two half-rings 16, threaded bores can be provided on the other side or each half-ring to receive the threaded shafts of the bolts 40.

[0030] Meanwhile, bolts or similar threaded fasteners 36 are provided for the bolt holes or bores 26 that can be tightened to draw in the corresponding tongues 24 for tightening the cylindrical tool sockets against the corresponding flashlight or similarly shaped tool.

[0031] A second embodiment, here shown with a somewhat configuration of the two ring-halves of the clamp, is illustrated in FIGS. 4A to 4D, where the same or similar elements are identified with similar reference numbers as in the first embodiment, but raised by 100, and thus need not be described in detail again. In this second embodiment (FIGS. 3A to 3D) there are recesses along the sides that relieve some of the material and weight, and there are open flanges 134 without maintaining the curved contour at the two ends of each of the half rings 116.

[0032] The sockets 120 have a preferred diameter of a nominal 1 inches, but this is not critical and the dimensions can be larger or smaller depending on the desired application. The sockets 120 and associated slots 122 result in a resilient tongue 124 that can be pulled in, i.e., bolted down to snug the respective socket against a tool fitted into it.

[0033] Rather the bolts or similar threaded fasteners as shown, these clamp holders can employ other elements to attach the two half-rings 16, 16 or 116, 116, and to pull in the tongues 24, 124 to assist in gripping the flashlight or similar tool.

[0034] These illustrated embodiments have four (4) sockets 20 or 120, spaced at about ninety degrees of arc from one another, that is each half-ring having two sockets spaced apart by ninety degrees of arc. However, there can be more or fewer sockets provided, and they need not be all the same size nor all have the same angular separation. Also it is possible to employ a clamp holder in which there are tool sockets only on one of the half-rings, and in some cases to employ a clamp holder formed of three or more arcuate components instead of the two half-rings.

[0035] FIG. 5 is a perspective of an implementation in which the annular clamp holder 12 is employed to attach a jetter hose 114 onto a suction hose. This can assist in removing or breaking up accumulations of solids and also in thinning denser material that may accumulate at the bottom of the septic tank. The jetter hose 114 is dimensioned to fit snugly into one of the cylindrical sockets 20 and is oriented parallel to the axis of the hose 10 and pointed in the distal direction (here, to the left). A flashlight or other tool can be mounted in one or another of the remaining sockets.

[0036] While the illustrated embodiment is adapted for use with a pumper truck, a clamp holder of this construction could find other applications where material is to be picked up and moved through a vacuum hose or suction hose, or on other cylindrical members.

[0037] While the invention has been described in terms of a preferred embodiment, many additional variations thereof are possible and would present themselves to persons of skill in the art without departing from the scope and spirit of this invention.
