United States Patent 2,987,080 DRAIN COCK TOOL Wilbur 0. Chandler, 415 W. th, and James A. Roberts, 414 W. 6th, both of Chanute, Kans. Filed June 3, 1959, Ser. No. 817,938 Claims. (Cl. 137-798) This invention relates to a multipurpose tool which is principally useful in connection with the operation and use of drain cocks of automotive vehicles.
An object of the invention is to provide a tool to facilitate draining of engine blocks and radiators of motor cars and trucks.
The same tool may be used not only to facilitate opening the draining cock but also to bleed off the water and anti-freeze, when used, so that the garage attendant does not become wet in performing this task.
The tool also functions as an adapter by which to connect a liquid conductor to the bottom of the radiator or engine block for reverse flushing.
An important feature of the tool is found in the actual construction thereof. It is very simple and yet it has numerous features. For instance the central passageway of the tool through which water or other liquid may pass, is so shaped and dimensioned as to receive a conventional wrench. When the knurled surface on the exterior of the tool is insufficient for manual gripping and turning the drain cock to the open or closed position, usually the former, the conventional tool may be inserted in the water passageway and the tool very easily turned thereby opening the drain cock. Once the drain cock is cracked open, the tool may be removed and a hose applied to the end of the tool to lead off the liquid before the drain cock is actually opened in an amount suflicient to enable water to flow from the radiator or engine block.
By using this tool for opening and closing drain cocks at considerable amount of damage usually caused by improvised or improper tools, is eliminated. At the present time a hammer, pair of pliers or any other tool at the disposal of the attendant is used for opening drain cocks. The instant special tool for drain cocks will serve the intended purpose effectively and eliminate a source of considerable damage to the radiator, engine block and drain cock.
Conventional drain cocks may actually be inserted or removed from the radiator or engine block by using the tool because of the conventional thread and nut of the drain cock which has been adopted as essentially standard in the current manufacturers makes and models of automobiles and trucks.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
FIGURE 1 is a fragmentary elevational view of a radiator showing a drain cock with a typical tool in accordance with this invention applied thereto.
FIGURE 2 is an enlarged elevational view of the tool in FIGURE 1.
FIGURE 3 is a bottom view of the tool in FIGURE 2.
FIGURE 4 is a sectional view taken on the line 44 of FIGURE 3.
FIGURE 5 is an elevational view of the tool showing a second use thereof.
FIGURE 6 is an elevational view of the tool of FIG- URE 1 but showing a wrench being used with the tool.
FIGURE 7 is an enlarged elevational view of a modification of the tool.
Patented June 6, 1961 FIGURE 8 is an elevational view, parts broken away fication of the tool.
FIGURE 9 is an elevational view, parts broken away in section, and showing a further modification of the tool and also illustrating a further use to which an of the tools may be placed.
In the accompanying drawings there is illustrated a part of a radiator 10 equipped with a conventional drain cock 12 having a handle 14. The radiator diagrammatically represents any conventional location for the standard drain cock 12 but has been selected since most of the drain cocks are located at the bottom of the radiator of the motor vehicle.
The longitudinal axis of the tool is coincident with the longitudinal axis of liquid conducting passageway 40 extending completely through the tool (FIGURE 4). Pas sageway 40 has an upper enlarged part 42 within which compressible, yielding resilient bushing 44 is disposed. The bushing is in the shape of a sleeve and may be made of rubber or some other elastomeric substance. The lower edge of the bushing 44 is disposed on shoulder 46 of passageway 40, and the bore 48 of the sleeve-like bushing is coincident with the longitudinal axis of passageway 40 and actually constitutes a part thereof. The upper surface 50 of bushing 44 constitutes a yielding seat against which the lower surface of the handle 14 comes to hear. The upper surface 50 of the bushing is normally above the lower edge of slots 28 and 30 so that the bushing must be compressed slightly when the tool is inserted on the handle 14 of drain cock 12 so that there is established a liquid seal at this point.
The lower end of the passageway 40 is non-circular to form a Wrench receiving socket 56. A conventional wrench 58 (FIGURE 6) may be inserted in socket 56 to facilitate turning the handle 14 of the drain cock. This may be in either the clockwise or counterclockwise direction.
In use tool 16 is applied to drain cock 12 as described. The outer surface of the tool is pressed by one hand and turned thereby opening the drain cock 12 by rotating handle 14. A knurled surface may be provided on the body of the tool to facilitate gripping. In instances where a Wrench is required or desired one may be used as shown in FIGURE "6. Circumferential grooves 22 and 24 are used to enhance a frictional grip with hose 62 that may be attached to the body of the tool by simply slipping it over the lower end thereof (FIGURE 5). This materially aids in conducting the water or other liquid from the engine or radiator without getting the attendant wet. As shown in FIGURE 9 a liquid conductor 64 having a hollow plug 66 at one end, may be attached to the tool by inserting the hollow plug into socket 56. It is clearly evident that the tool may be used not only for tightening and loosening the drain cock 12 but also to conduct off the liquid and also to apply liquid under pressure into the radiator 10 or engine block for reverse flushing.
3 Attention is now invited to FIGURE 7. Tool 70 shown in this figure is exactly the same in all details of Christmases" sensor 16 withthesole exception that the bayonet slots 26a and 28a have short projections 72 and 74,at the. entrances thereof in. order to latch the handle 14 in place in the slots. FIGURE 8 illustrates a further embodiment of the invention. Tool 76 is essentially the same as the tools 16 and 70. This figure. illustrates a knurled surface 78.1'eferred to in connection with tool 1 6 and which may be used on tool 70 or any other tool in accordance with the invention. In addiiton slots 26b and 28b have angulated lower surfaces 80 and 82 to serve as cams in locking the tool onto the drain cock. Tool 86 in FIGURE 9 shows a variation in the material of construction. The previously described tools are made of metal, but it is Within the purview of the invention to use a suitable, commercially available plastic such as nylon or some other synthetic resinous material having the proper hardness and heat resistancecharacteristics.
The foregoing is considered as'illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
