Abstract
Transmission Filler Assembly Abstract Service personnel may confuse one dip stick for another in vehicles having a number of fluid reservoirs. When the reservoirs have air entrapped within them during filling, hydraulic lock can occur.
Herein, a filler tube structure and a dip stick tube structure have their top ends held within a tubular fitting which is covered by a single cap. This eliminates any possible confusion as to the dip stick tube structure which corresponds to a particular reservoir or chamber. In the preferred embodiment venting of the chamber to which the fluid is being added is provided via an interior passage of the dip stick tube structure, thus preventing hydraulic lock.

Description Transmission Filler Assembly Technical Field This inVention relates generally to an assembly for filling a closed interior chamber and more particulaxly to an assembly for filling a transmission with a liquid lubricant.
Background ~rt On earthworking equipment and other vehicles there are often several chambers which must be periodically filled with fl~lid to a desired level. For example, one chamber may hold engine lubricating oil, another may hold transmission fluid, still another may hold brake fluid, etc. To determine when a particular chamber must have fluid added, it is customary and convenient to utilize a dip stick.
Since there are several chambers which may need filling, there must be a corresponding number of dip sticks. This creates a problem for service personnel of determining which dip stick corresponds to each cham~er, Nor~ally, the dip sticks and fluia addition ports are correspondingly labelled.
However, such labelling can become obscured due to dirt~and/or wear. Hence labelling alone is not an adequate solution to the problem.
While it is well known to vent chambers ~, s such as gasoline tanks and water tanks when they are being filled, an adequate assembly has not heen available for accomplishing this with a closed pressure system such as a transmission, particularly through utilizing the filler assembly for this purpose upon disengaging its cap. ~et, it is particularly important to assure that an adequate air vent is present in such a system to normalize transmission pressure since hydraulic lock could occur, particularly when oil viscosity is relatively high as during cold weather, if proper venting has not taken place.
The present invention is directed to overcoming one or more of the problems as set forth above.
Disclosure of the Invention In one aspect of the present invention an assembly is provided for adding oil to a closed interior chamber defined by a case. A filler tube structure having input and exit portions has the exit portion thereof in communication with a top portion oE the chamber. A dip stick guide tube structure has an interior passage in which a dip stick normally fits. The upper end portion of the guide tube structure is positioned adjacent and generally parallel to the input portion of the filler tube structure. ~ tubular fitting is provided which has first and second end portions with the first end portion being .~
circumferentially sealed to the upper portion of the guide tube structure and to the input portion of the filler tube structure. The cap is removably attachable in covering relation with the second end portion of the tubular fitting.

Figure 1 shows an assembly lO for adding a liquid to a closed interior chamber 12 defined by a case 14. The chamber 12 has a top portion 16 and a bottom portion 18. The case 14 would be the case for a transmission (not illustrated), in accordance ~S3~15 with the preferred embodiment of the invention.
However, it should be realized that the invention is not limited to an assembly 10 for filling only a transmission.
A filler tube structure 20 has an input portion 22 and an exit portion 24. The exit portion 24 is in communication ~ith the top portion 16 of the chamber 12. The input portion 22 is generally above the exit portion 24 so as to provide gravity driven flow. Adverting temporarily to Figure 3, it will be seen that a bore 26 is formed in a flange 28 which extends generally : upwardly from the case 14. The exit portion 24 of the filler tube structure 20 is connected to the bore 26 which then communicates with the top ` 15 portion 16 of the chamber 12.
A dip stick guide tube structure 30 has an interior passage 32 ror receiving a dip stick 34.
The dip stick guide tube structure 30 has an upper end portion 36 and a lower end portion 38. The upper end portion 36 is positioned adjacent and generally parallel to the input portion 22 of the filler tube structure 20. Generally, the upper end portion 36 of the guide tube structure 30 is positioned generally above the input portion 22 of the filler tube structure 20. In this manner, when fluid is added to the input portion 22 of the filler tube structure 20, it will generally not flow into the upper end portion 36 of the guide tube structure 30.
A tubular fitting 40, having a first 3~5 end portion 42 and a second end portion 44, has the first end portion 42 thereof circumferentially sealed to the upper end portion 36 of the guide tube structure 30 and to the input portion 22 of the filler tube structure 20. In the particular embodiment illustrated, a wall 46 is formed across the first end portion 42 of the tubular fitting 40, with the wall 46 having a first hole 48 to which the input portion 22 of the filler tube structure 20 is sealingly attached.

The dip stick 34, as previously mentioned, is adapted to fit in the interior passage 3~ of the guide tube structure 30. The dip stick 34 has a lower end 54 and an upper end 56, and a handle 52 is attached adjacent the upper end 56 and is of a size and construction to fit within the tubular itting 40. A cap 58, normally of a conventional variety and having conventional pressur.e release threads to allow release of internal pressure prior to removal and to thereby prevent splattering out of fluid r is removably attachable in a covering, generally sealing, relationship with the second end portion 44 oE the tubular fitting 40. The handle 52 of the dip stick 34 is also of a size and construction to be free from in~erference with the cap 58. In this manner, anyone wishing to add fluid to the chamber 12 and removing the cap 58 will immediately find the handle 52 of the dip stick 34.
In accordance with the preferred embodiment of the invention, a venting structure 60, seen best in Figure 3, serves ~or venting air which may become entrapped in the chamber 12 on addition of fluid thereto via the filler tube structure 20.
Basicallyr the venting structure 60 includes a venting passage 62 having one end 64 communicating with the top portion 16 of the chamber 12 and having another end 66 communicating with the interior passage 32 at a location external of the case 14.
The vent passage 62 includes a first portion 68 communicating the top portion 16 of the chamber 12 with a block 70 which is attached, for example by bolts 72 (see Figures 1 and 2) to the case 1~, and more particularly to the flange 28 adjacent the top portion 16 of the chamber 12. The vent passage 62 also has a second portion 74 which communicates the first portion 68 with the interior passage 32 of the guide tube structure 30.
Basically, the first portion 68 is a bore in the Elange 28 and the second portion 74 is a passage ~ormed in the block 70.
