Measurement tool used with an indicator

[0002] 1. Field of the Invention

[0003] The present invention relates to a measuring attachment for an indicator and more particularly pertains to a new measurement tool used with a dow indicator for simplifying the task of measuring a hard-to-reach surface of an object.

[0004] 2. Description of the Prior Art

[0005] The use of measuring attachment for an indicator is known in the prior art. More specifically, measuring attachment for an indicator heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

[0006] Known prior art includes U.S. Pat. No. 2,062,961; U.S. Pat. No. 2,199,236; U.S. Pat. No. 2,456,497; U.S. Pat. No. 1,806,893; U.S. Pat. No. 4,809,440; and U.S. Pat. No. Des. 252,501.

[0007] While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new measurement tool used with an indicator. The inventive device includes a cylindrical member having a first and a second end and a bore extending therethrough and a first longitudinal slot and a second longitudinal slot; and also includes a shaft moveably disposed in the bore and having a collar securely attached thereabout to limit the movement of the shaft in the bore; and further includes a linkage member pivotally attached to the shaft and moveably disposed in the first longitudinal slot and being pivotally attached to an arm member; and further includes a fastening member securely mounted to the cylindrical member for tightly securing the indicator in the cylindrical member with the shaft being in contactable relationship with the indicator.

[0008] In these respects, the measurement tool used with an indicator according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of simplifying the task of measuring a hard-to-reach surface of an object.

[0009] In view of the foregoing disadvantages inherent in the known types of measuring attachment for an indicator now present in the prior art, the present invention provides a new measurement tool used with an indicator construction wherein the same can be utilized for simplfying the task of measuring a hard-to-reach surface of an object.

[0010] The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new measurement tool used with an indicator which has many of the advantages of the measuring attachment for an indicator mentioned heretofore and many novel features that result in a new measurement tool used with an indicator which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art measuring attachment for an indicator, either alone or in any combination thereof.

[0011] To attain this, the present invention generally comprises a cylindrical member having a first and a second end and a bore extending therethrough and a first longitudinal slot and a second longitudinal slot; and also includes a shaft moveably disposed in the bore and having a collar securely attached thereabout to limit the movement of the shaft in the bore; and further includes a linkage member pivotally attached to the shaft and moveably disposed in the first longitudinal slot and being pivotally attached to an arm member; and further includes a fastening member securely mounted to the cylindrical member for tightly securing the indicator in the cylindrical member with the shaft being in contactable relationship with the indicator.

[0012] There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

[0013] In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways.

[0032] With reference now to the drawings, and in particular to FIGS. 1 through 5 thereof, a new measurement tool used with an indicator embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

[0033] As best illustrated in FIGS. 1 through 5, the measurement tool 10 is highly suitable for use with an indicator 37, and is most preferably used with a dial indicator. The measurment tool 10 generally comprises a cylindrical member 11 having a first end 12 and a second end 13 and a bore extending 14 therethrough and a first longitudinal slot 15 extending from the first end 12 and a second longitudinal slot 16 at the second end 13. The first longitudinal slot 15 terminates intermediately of the cylindrical member 11. The cylindrical member 11 also includes a flange 35 securely and integrally attached to the interior of the wall of the cylindrical member 11 inside the bore 14 near the second end 13 thereof and has a length ranging from approximately 6 inches to 24 inches with the bore 14 having a diameter of approximately ⅝ inch. A means for taking measurements of a surface includes a shaft 17 slidably disposed within the bore 14 of the cylindrical member 11 and having a first end 18 and a second end 19 and being adapted to be in contactable relationship with the indicator 37; and further includes a linkage member 21 having a first end 22 pivotally attached to the shaft 17 and also having a second end 23; and also includes an arm member 24 being pivotally and conventionally attached at the first end 12 of the cylindrical member 11 and having a first end 25 pivotally and conventionally connected to the second end 23 of the linkage member 21 and also having a second end 26 for measuring a surface of an object. The shaft 17 includes a collar 20 securely disposed thereabout near the first end 18 thereof and being capable of coming into contact with the flange 35 for limiting movement of the shaft 17 within the bore 14. The first end 18 of the shaft 17 includes a seat adapted to be in contactable relationship with a probe 38 of the indicator 37. The first end 22 of the linkage member 21 is pivotally and conventionally connected to the second end 19 of the shaft 17. The linkage member 21 is moveably received in the first longitudinal slot 15. The arm member 24 has a central portion which extends in the bore 14 through the first end 12 of the cylindrical member 11. The second end 26 of the arm member 24 is adapted to move and measure a deflecting distance of a surface of an object being measured in thousandths of an inch. The shaft 17 is slidable in relationship to movement of the second end 26 of the arm member 24 and is adapted to translate the movement to the indicator 37 in thousandths of an inch. A fastening member 27 is securely and conventionally attached to the second end 13 and is adapted to secure the indicator 37 in the cylindrical member 11 through the second end 13 thereof. The fastening member 27 includes a pair of brackets 28, 29 securely attached and welded on opposite sides of the second longitudinal slot 16 and also includes a fastener 30 threaded through the brackets 28, 29 to securely tighten the second end 13 of the cylindrical member 11 about a portion of the indicator 37.

[0034] As a second embodiment, the measurement tool includes an extension member 31 having a bore 32 extending therethrough and further having a first end which is fastenable to the second end 13 of the cylindrical member 11; and also includes a clamping member 33 having bracket members 34 and a securing member 36 threaded through the bracket members 34 and being securely mounted at a second end of the extension member 31. The indicator 37 would be securely inserted in the second end of the extension member 31.

[0035] In use, the user secures the indicator 37 in the second end 13 of the cylindrical member 11 and secures the measurement tool 10 in a lathe or a vice and extends the measurement tool 10 inside an object 40 to be measured and allows the arm member 24 to rest upon the surface inside the object 40 and moves or rotates the object 40; whereupon the arm member 24 will pivot thus moving the shaft 17 which translates the measurement of the particular surface in thousandths of an inch to the indicator 37.

[0036] As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

[0037] With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

[0038] Therefore, 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.
