AUTOMATIC PRESSURE GAUGE Filed Jan. 21, 1929 INVENTOR .ZLPlafl' ATTORN EYG Patented Nov.'15, 1932 -.,,UN,I,TED STATES ,1 BARB E. PLATT, or o'rirnmwa, IOWA "-au'rona'rrc PRESSURE GAUGE f Application filed J'anuary21,fl1929. Serial No, 333,967.
My invention relates to improvements in automatic pressure gauges, and it consists in the combinations, constructions, and arrangements herein described and claimed.
An object of my invention is to provide an automatic pressure gauge which may be used for air, gas, steam, or liquids, but which is especially adapted'for use in connection with pressure tanks for passing air under pressure into vehicle tires.-
A further object of myinvention is to provide a device of the type. described which may be adjusted-so as to allow a predetermined amount of air under pressure to enter the tire. A 5 further object of my invention is to provide a device of the type described in which the adjusting means is disposed where it can be readily actuated.
A further object of ,my' invention is to provide a device of the type described which hasnovel means-for indicating to the operator when the main valve is opened and when the main valve is closed. 7
7 Other objects and advantages will appear in the following specification, and'the novel features of the invention will be particularly pointed out in the appended claims.
My invention is illustrated in the accom panying drawing forming. part of this application, in which 4 I Figure 1 is a vertical sectional view of my device, portions thereof being shown in elevation, f 1 V .Figure 2 is atop plan view of a portion of my device, I i V Figure 3 isan enlarged detail view of a signalling means, and i Figure 4 is a sectional view takenalong the I line l- 4 of Figureil. I
Incarrying out my invention I provide a body portion 1, having a main inlet-passage way-2 and an outlet passageway 3 separated fromeach other by means-of a partition ,4
but arranged to communicate with each other through an opening 5 provided in the partition. A cylinder 6 is provided inthe body portion 1, and is provided with an open end 7 whichis arranged to receive a cover 8.
. A valve piston 9 is movably disposed in the cylinder Band is provided'with stop menu-- spring supporting piston 11-. q A signalling meansis prov bers 10 which extend upwardly and are "are ranged toengage with the cover 8.1 A spring supporting rpiston 11 is movably disposedin the cylinder ,6 and is provided with a center opening12fl Avalve stem 13, "whichhas' a main valve 1 1 mounted upon oneend, slidably extends through the opening 12 and has the otherend rigidly secured to the valvepiston 9. A compression spring 15 is disposed between the two pistons 9 andll. -An actuating lever 16 has one end] con nected to thebody portion by means of a connectinglink 17. Supporting arms-18 are rigidly carried by the cover 8and pivotally support. actuating links 19. The actuating links 19 each have one of their ends zpivotally jconnected to the lever 16 .at amend their 2vother ends operatively. connected i Q {draw rods 21. The draw rods 21 are slidably disposed in packing members 22 whichare cart;w
ried by the cover 8. The draw rods 2l slidablyextend through the valve'piston 9 and have their inner ends rigidly secured tofthe whistle. portion 2%]: disposed therein. This tubular portion is carried by the cover; 8 and is provided withan air inlet opening '25. An
inner tubular member 26 is carried by the;
when opened. 'Aby-pass 29 is disposedin the body portion 1 for providing communication between the passageway 3 andthe upper portion of the cylinder 6.
An indicating. arm 30 is pivotally secured to the body portion -1 at 31 and is provided with a plurality of teeth 32. Theteeth .32
ided and is com-Q posed of an outertube 23having a cut-away provide notches .33 adjacent to which are disposed indicating lines -34. The indicating arm 30 extends through an opening35 in the I lever 16. A tongue member 36 is carried by under pressure to the body portion. Let us further assume that the operator wishes to pass air under pressure into'a-tireruntil the pressurein the tire has reached forty pounds.
The operator will first force the lever 16 downwardly by pressing upon the handle portion 39'until the tongue portion 36 is disposed in the notch 33 adjacent the indicating line numbered40 upon the indicating arm 30. By pressing the lever 16 downwardly, the draw rods 21 will be moved upwardly thus moving the spring supporting piston 11 upwardly in the cylinder 6, The tension of the spring 15 will also force the piston 9 upwardly carrying with it the valve. 14. The movement of the piston 9 in the upward direction is limited by means of the stop members lOlso that the piston 9 will atall times be positioned beneaththe outlet of the by-pass 29. If the piston 11 is moved upwardly a greater distance than the piston 9 is allowed to move, the spring 15 willbe compressed to take'care of this additional movement of thepiston 11.
When the main valve 14 is moved away from the openingt, the air under pressure is allowed to pass from the inlet passageway 2, through the opening 5, and into the passageway 3. By connecting the end of the body portion adjacent the valve 28 with the valve stem of the vehicle tire, the valve 28 will be moved from its seat thus allowing the air under pressure to enter the tire. The
air under pressure will continue to pass into the tire until the pressure in the tire has reached forty pounds. The pressure in the outlet passageway, 3, the .by-pass 29, and the cylinder 6 will be the same as in the tire. The spring 15 is of such a tension that'the main valve 14 will beheld open until the predetermined amount of air has passed into the tire. This predetermined amount of air will be suiiicient pressure to force the'pi'ston 9 downwardly against the tension of the spring and close the valve'14.
During the movement of the valve 9 in the upward direction the opening 27 of the sig nailing means will align with the opening 25 and then pass beyond the opening 25.
. When the opening 27 is in alignment with r the opening'25 a portion of the air underpressure will pass through these openings and through the opening 24 creating a whistling I sound. This sound will notify the operator that the main valve 14 has been opened. After the desired amount of air has passed into the'tire the piston 9 is forced downwardly thus closing the main valve 14. The openbetweensaid inlet and outlet passageways,
said partitioning portion having an opening therethrough, a valve member normally disposed in said opening and seating on said partitioning portion, said body'portion being provided. with a cylinder," a cylinder head removably connected with the body portion, an upper and a lower piston member movably disposed in said cylinder in spaced-apart relation, spring means disposed between said spaced-apart piston members, said upper piston member being provided with stop members for limiting the movement thereof, said body portion having a passageway for providing communication between the outlet passageway andsaid cylinder between the upper'piston member and the cylinder head,
said main valve'being provided with a valve stem slidably extending through said lower piston member and fixedly connected with the upper piston member, a'pair of actuating rods fixedly connected withsaid lower piston member and slidably extending through said upper piston member and'the cylinder head,
an actuating. lever, -link means operatively connecting said actu ating lever with the body through an opening in said actuating lever, said arm being provided with indicia opposite the notches, and means mounted on said lever for engaging the notch-es-of said indicating arm. H
