2 Claims. (Cl. 7337.5)

This application, a division of Ser, No. 290,526 of June 25, 1963, now Patent Number 3,170,318, discloses a cabinet type multiple column air flow gage, one important element of which is a sectional valve body unit comprising side by side separate valve bodies secured together into a unit, each having its own built in bleed valve and by pass valve, and its own air tube, return air flow conduit, gage element, outlet conduit, and air supply conduit, with such unit sup-porting cabinet sides in turn supporting other parts of the device.

A preferred form is shown in the following specification and appended drawings.

In these drawings:

FIG. 1 is a partly broken away front elevational view of the present air flow gage device providing a plurality of separate indicating columns for a plurality of simultaneous gaging operations.

FIG. 2 is a partly broken away rear elevational view thereof.

FIG. 3 is a partly broken away plan view thereof, to an enlarged scale.

FIG. 4 is a vertical section on lines 44 of FIG. 1, to an enlarged scale.

FIG. 5 is an enlarged section of the valve body per se.

The air gage housing or cabinet shown includes base 11 upon which is mounted a sectional valve body comprising adjacent separate valve bodies 12 with end spacers 15, and secured to the base by screws 17. Pins 13-14 and fasteners 16 connect the separate valve bodies 12.

Cabinet side members 18 connect to and are connected by said valve body unit 10 by fasteners 19. Manifold covers 20 are secured at 21 tosides 18, and include circular bosses 22 which project within opposite ends of air manifold 23, sealed by O-rings 24. Nipple 25, FIG. 4 supplies air under pressure to manifold 23.

The cabinet includes rear wall 26 secured by fasteners 27 to manifold covers 20. Removable top 28 extends along the upper back portion of the housing as at 28 and includes a depending front Wall portion 29.

An upper tube support block 30 with end mounting brackets 31 is between side walls 18 and is secured thereto by fasteners 31, FIG. 2. Top 28 is secured to tube support 30 by fasteners 60".

Tube support 30 has longitudinally spaced vertical bores, FIG. 4, within each of which is adjustably positioned a tube clamp 32, Whose undersurface is recessed to receive gasket 33 which retains the upper end of upright glass tube 35. Clamp screw 36 threads down through tube support 30 and operatively engages clamp 32 which may be further secured by set screw 36'.

Valve body 12, FIG. 4, includes seat 37 and gakset 33' seating the lower end of tube 35.

Seat 37 has an inlet 38 which projects down into intake chamber 44, which has an inlet 43 in body 12.

Though a plurality of separately operated pressure regulators are shown at 39, FIGS. 2 and 3, mounted upon rear wall 26, only one such regulator is described in connection with FIG. 4. Said pressure regulator is connected with manifold 24 by conduit 40. Delivery conduit 41 connects pressure regulator 39 and inlet fitting 42 of valve body 12 for supplying air under predetermined pressure to intake chamber 44 through inlet 43.

3 263,490 Patented August 2, 1966 ice Float 45, FIG. 4, is movably positioned within tube 35. Axially arranged bumper 34 at the upper end of tube is apertured to permit passage of air through passage 46 in clamp 32 and out through return conduit 47, which returns air to inlet 48 of valve body 12 and to delivery chamber 49. Through fitting 50' said air passes through conduit 50 to gaging element 51 which has one or more leakage orifices 52. Each of the valve bodies 12 has an intake chamber 44, a delivery chamber 49, with connected gaging parts 50, 50', 51; conduits 41, 47; and tube 35.

A longitudinally apertured valve core 54 is snugly fitted to the rear end of a bore B of the valve body 12 to cooperate With valve sleeve 53 which is adjustably threaded into bore B of valve body 12 and which includes at its outer end on the exterior of the body a knob K for manual rotation. The inner end of valve sleeve 53 extends around a reduced part of valve core 54. Teflon plastic seals 64 are provided.

As shown, valve sleeve 53 has been rotated and moved outwardly partially from core 54 to provide a bypass aperture 55 by which some of the air delivered to intake chamber 44 is by-passed into delivery chamber 49 and does not pass upwardly through tube 35.

An air bleed valve includes spindle 56 which is threaded within the bore of valve core 54, and is located within valve sleeve 53, and outwardly thereof terminates in the knurled adjusting head 57.

The inner tapered end 58 of spindle 56 projects into a bore 59 of a valve seat 60 threaded into the rear end of valve core 54 and sealed at 61.

The amount of air bleed is determined by rotative adjustment of spindle 56-57 and the corresponding valve element 58 with respect to seat 60.

In the present construction and normally where there are a series of bores or other part dimensions to be checked on a workpiece such as the block of an engine or the like, there are provided a series of gaging elements 51, one corresponding to each valve body 12 and tube 35 and float 45.

The air manifold 23, FIG. 4, provides a supply of air under a predetermined pressure which may be used by all of the gaging assemblies.

The air flows into intake chamber 44 and up through tube 35, with float 45 therein responding to the movement of air and thus by its position in tube 35 indicating the rate of flow of air.

In order to visibly indicate this effect, due to air leaking through gage element 51-52, there is provided a suitable upright scale 64.

Side walls 18 mount brackets at 66 for supporting a background plate 67 behind tubes 35. Plate 67 mounts spacers 68 which mount scales 64, 69, using fasteners 70.

Conclusion It will be seen that the device includes a valve body unit 10 FIG. 3, comprising separate valve bodies 12 connected by pins 13-14, each valve body 12 containing valves 53 and 56; each body 12 having a tube 35 leading to tube support 30; each body 12 having an air return conduit 47, an outlet conduit 50, and a gage element 51; and that cabinet side members 18 connect to and are connected by the valve body unit 10, tube support 30 and manifold 23; the latter having conduits 40- 41, one set 40-41 for each body 12.

I claim:

1. A cabinet type multiple column gage comprising a single elongated base;

an elongated sectional valve body unit horizontally disposed and mounted on and secured to said base, and comprising a plurality of separate short valve bodies side by side and closely adjacent; with locking pins passing horizontally through these valve bodies to connect them to one another and thus form said valve body unit; with each valve body containing a bleed valve and a bypass valve;

a horizontally disposed elongated single air tube support well above said valve body unit and parallel to it;

vertical air tubes or columns, one for each valve body,

connecting said valve body unit to said support;

gage elements, one for each valve body;

outlet conduits, one for each valve body and each gage element, with each conduit connecting a valve body and a gage element;

cabinet side members connected at their lower ends to the ends of and thus connected by said valve body unit; and connected at their upper ends to the ends of and thus connected by said support;

an elongated single air supply manifold parallel to but alongside said valve body unit and having air supply conduits, one for each valve body, connecting the valve body unit to said manifold;

said manifold being connected at its ends to and thus connecting said side members.

2. The combination of claim 1 including air pressure regulators mounted on said base, one for each valve body connecting the valve body unit to said manifold.
