GAGE.
To all whom it may concern: v
Be --it known *that I, CHARLES E. COATS, a citizen of no country, and a resident of the borough of Manhattan, city, 'county, and
State of New York, have invented certain new and useful Improvements in Gages, 0f which the following is a specification.
This invention relates to improvements in gages, and more particularly to testing gages of the liquid-column type. 2 The invention has for its objects to provide a gage of theclass set forth constructed of a minimum number of parts which may be readily assembled and dismantled; to simplify the construction and increase the durability and efficiency of the indicating-fluid reservoir to provide more efficient means foradjusting the indicating means bodily relatively to the base of the gage; to provide improved means for varying the capacity of the indicating-fluid reservoir; and to provide a gage of the type set forth so constructed as to increase the utility and durability thereof.
In the drawings,Figure 1. is a side eleva tion of the improved gage;
/ Fig. 2 a front elevation thereof;
Fig. 3 a vertical section on the line III III of Fig. 2; 7
Fig. 4 a sectional plan on the line IV'- IV of Fig.2; and r l Figs. 5 and 6 detail views, partly in vertical section illustrating thev operation of the gage and theconstruction of the fluid reservoir. i i
Referring to the various parts by numerals, the base of the gage has an article supporting block or plate 1 detachably held to the upper side thereof by suitable screws. An angular member 2 is held to the block lby means of-a' clamping screw 3 which extends through an elongated slot in the horizontal portion of said member, whereby the member may be adjusted to shift the upstanding article-supporting and alining portion thereof relatively to a vertically reciprooable plungerfl. The member 2 is formed with sultable guiding ribs 35 whlch slidably engage in groovesorchannels in 1 the block 1, and the block 1 is preferably provided with a plurality of threaded sock-- ets in either of which the screw 3 may be threaded, as more clearly shown in Figs. 2, 3 and 4.
The indicating means isvsupported above Specification of Letters Patent. Patented J ly 20 1920 Application filed. October G, 1919. Serial No. 328,726.
the block 1 on the forward end of a vertically adjustable arm 5. The arm 5 is formed with an integral sleeve or collar 6 which embraces a vertical post 7 rigidly held at its lower end to the base of the gage. The sleeve 6 and arm 5 are held against rotary movement about the post 7 by a key 8 held to the sleeve 6 by a suitable screw 36'and engaging in a key way 37 formed in the post, as more clearly shown in Figs. 3
and 4..
The lower end of sleeve 6 is threaded internally to receive the reduced threaded upper portion of an adjusting nut 9, which has a reduced threaded lower portion screwed into the internally threaded upper end of a collar 10 and is also provided with a central aperture through which the post 7 extends. Thev threaded connections between the sleeve and nut and the collar and nut are of opposite pitch and the threads are of low pitch, for example d0 pitch, to permit of fine adjustments of the arm 5 and sleeve 6 up or down relatively to the collar 10 byrotating the nut 9. The arm 5, sleeve 6,fnut 9 and collar 10 may be simultaneously and quicklymoved up or down on the post 7 for coarse adjustments, by means of a pinion 11 which meshes with teeth 12 formed on the flattened forward side of post 7 and is rotatable by a shaft 13 journaled in the collar 6 and having a finger wheel 14 fixed on one end thereof. The collar 10 has a split lower portion controlled by a clamping screw 32 for clamping the collar on the post in its adjusted position.
The arm 5 isformed with a circular recess in the under side thereof adjacent its forward end, and is also formed with an annular upstanding flange 15 on its upper side concentric with an aperture communicating with said recess. An indicatingfiuid container, chamber or receptacle 16 of circular form and preferably constructed of brass, is removably held in the recess in arm 5 by a closure member or cap 17 screwed into said recess and formed with a depending tubular extension through which the plunger or pin l slidably extends. The vertical wall of reservoir 16 is relatively thick and is rigid, while the top and bottom walls thereof are thin and flexible. The bottom wall is preferably formed by turning the edge of a brass or other suitable metallic diaphragm 18 upwardly around the outer side of the undercut lower end of' the circular vertical wallrof the reservoir and soldering or otherwise securing the upturned edge of the diaphragm to said vertical wall so as to form a liquidtight connection, the top, bottom and side walls of the reservoir becoming practically integral with each other.
The plunger 4 is provided with a slot or groove 33 into which a screw 3 1 threaded through cap 17 extends. Screw 34: prevents the plunger from dropping out of contactwith a small metal disk19'soldered or otherwise secured to the under side of the flexible diaphragm 18. The disk 19 serves to stiifen the central portion 01 the diaphragm and thereby augments or magnifies the ac tion of the diaphragm in displacing the indicating fluid in the reservoir when the diaphragm is pressed upwardly by the plungei' 4.
- The upper flexible wall of the reservoir 16 is formed with a rigid tubular extension 20 which projects upwardly through arm 5 and the annular flange 15 formed on said arm and serves to support a glass indicat ing tube 21. The extension 20 is closed at its lower end except for a small central aperture which registers with the fluid passage in the glass tube 21. The glass tube is rigidly but detachably held at its lower end in the extension 20 by a nut 22 threaded into the upper end of the extension and bearing-upon a metallic washer 38 which rests upon a suitable compressible packing ring 39. By unscrewing the cap 17, said cap and the plunger 1 may be disconnected from the arm 5,and the fluid reservoir and indicating tube 21 maythen be withdrawn as a unit.
The capacity or" the reservoir 16 may be varied-to raise or lower the normal level of the indicating liquid in tube 21, by means of a screw 23 threaded through the arm 5 and engaging the flexible top wall of the reservoir. The tube 21 is protected by a tubular metallic casing 2+1 the front side of which is cut away intermediate the ends thereof to permit observation of the liquid.
level in the indicating tube. Two vertical posts 25 and 26 arranged at opposite sides of easing 2st are rigidly held to a support or bracket 27, tightly but removably clamped upon the casing 24 by means of a plate 28' and suitable screws threaded through said plate into said bracket. Three pointers 29 are slidably mounted on the post 25 for independent vertical adjustment, said pointers being frictionally held in their adjusted positions and being preferably formed with finger pieces, as shown, to facilitate adjustment thereof onthe post. The usual graduated indicator plate, bar or leaf 30 is supported on the post 26 and is adjustable vertically thereon, a suitable set screw 4-0 be ing provided for holding the plate or lea 30 in its adjusted position. The tubular casing 2a is split at its lower end and is removably but rigidly held to the flange 15 on arm 5 by a split clamping ring 31, as clearly shown in Figs. 3 and t. The liquid reservoir is filled in the usual way, bypouring the indicating liquid into the usual flaring funnel-shaped upper end of the indicator tube 21, the casing 24. being provided with the usual removable cap 41 at its upper end.
In using the gage, the lowermost pointer 29 is adjusted to register with the top of the liquid column in tube 21and the other two pointers, are adjusted until they are spaced apart a distance on the scale. plate 30 corresponding with the permissible varia tion in size ofthe articles to be tested from a master piece or, article of the desired size. The master piece is then placed on the block 1 and theclamping ring 10 lowered and arm 5 adjusted by means of the pinion 11 and finger wheel 1 1 until 'theplun 'er 1 almost engages the master piece. fiollar 10 is then, clamped to the post by. tightening screw 32, and nut 9 is rotatedslightly un til plunger 4: engages the master piece and is forced upwardly, nut 9 being turned until the level of the liquid in tube 21 reaches the proper point between the two uppermost pointers. The gage is thus set and ready for use in testing the articles to determine whether or not they "conform sufficiently closely with the master piece. If the level of "liquid in tube 21 should rise above or fall below the lower pointer by reason of'leakage, evaporation, or expansion and contraction due to changes in temperature, the liquid level maybe adjusted to again register with the lower pointer by adjusting the screw 23 to increase or decrease the capacity of'the reservoir 16 as may be required, thus avoiding the necessity of entirely re-setting the gage.
