SIGNAL VALVE Application filed Getober 8, 1919.
To all whom it may concern.
Be known that I, FRANK N. KnLsnY a citizen of the United States, residing at New Haven, in the county of New llaven and t tate ot (kmnecticut have invented certain new and useful lin in'ovemonts in tBignal Valves, oi which. the ipllim'ing specification, rcli'eren being; had therein to the accompanying drawings.
This invention relates to new and useful iin'iprcvcinents in signal valves and is destem of the inner tube of an automobile tire and to operate when the air therein exceeds a predetermined pressure.
ll hile the invention is herein shown and described as applied to mechanism substantially as above set for 11 I oesire to have it understood that it has other uses and is applicable in connection with any mecnanism wherein air is under pressure in a confined space. i
lit the object of my invention, among other things, to produce a device of this character that will be positive .in its operation, produced at the minimum cost, which may be readily attached and detached without disarrangement of its parts and will withstand hard wear and usage.
'lo these and other ends. my invention consists in the signal valve, having certain details of construction and combinations of parts as will be hereinafter described. and more particularly pointed out in the claims.
l teferringr to the drawings, in which like numerals reference cesignate like parts in the several figures Figure 1 a view 0 t my improved device complete t Figure 2 is an enlarged sectional view, taken substantially upon line 2-2 of Figure 1;
Figure 3 is a sectional view of a portion of the ntiechanisni, taken upon line 8-3 of Figure 4; and
Figure 4: is a sectional view of the parts taken upon line 4 .4t oi Figure 3.
Referring to the drawings the numeral 10 designates the valve body having a chamber ii therein that opens into a larger chamber l2- these being separated by a shoulder or valve seat 13. llpon one side of the valve bod v is an auxiliary chamber is connected with the chamber 12 through the port .13. .red, in one end o1" the valve body 10 is a Serial No. 329,380.
plug 16 having a port 17, from the outer end of which radiate the lateral ports 18.
Loosely mounted upon tne plug 16 is a nut ll) which has a tree en dwise movement thereon between the end o1 the valve body 10 and the collar 0 and is provided with internal threads, which engage the threaded end of the valve stem 21, connected with the said inner tube and shown in the drawings by broken lines.
hziovable within the valve body 10 is a sleeve 22 having a collar 23 thereon against which lies the gasket 24: and fixed in one end of which is a plug 25. Within this sleeve is a rod 26 that passes through'the opening 28 in the plug 25, having a head 27 at one end and a head28 at the opposite end. One of these heads may be integral with the rod and the other secured thereto in any Well known manner. Adjacent to the head 27 is a gasket 29, which in one of its positions is held against the valve seat 30 at the end of the sleeve 22 and the plug :25 by the spring 31.
.hreaded upon the exterior of the shank ot the valve body 10 is the compression cap" 333 having a chamber 234i therein, into which opens the port 35. The compression cap 33 is graduated as shown at 36 in Fig;
ure 1 to indicate various pounds pressure and is knurled at 37 so as to insure a tight grip while threading on and off the valve body. This cap is provided at its outer end with an enlarged head 38, which is projected into the opening of dfiQXlblG tube 39., which is connected with an air pump.
A nut l0 threaded. on the shank pro v ides means for locking the compression cap in its adjusted positions. The walls of the chamber 12 are internally threaderh the pitch thereofcorresponding with the external threads on the shank 32, and threaded thereon is the spring cap 41, having radial. wings 42 that project into recesses or slots 43 in the compression cap 33. By this connection between the spring and compression caps the movement of the latter is imparted to the former, one however being" rotz'ttably mounted within the shank 32 and the other upon the exterior thereof,
A spring as lies within the spring cap 4L1 andv abuts at one end against the collar 23 on the sleeve 29, and at the other end against the end wall as) oi. said, cap, through which an opening; 50.
Secured to the valve body 10 by the screw 4i? so as to normally cover the auxiliary chamber is: is the diaphragm 4%, which is held against lateral movement by the lips as. This diaphragm is provided at one end with a notch 49, which serves as an indicating line with which the graduations 36 are brought into register for determining the air pressures desired.
In practice this device remains attached to the pump tube .39 and is applied to the inner tube by threading the nut 19 on, to
the valve stem thereof, the end of the plug Hi opening with the valve therein, as is usual. When so applied all oil? the parts oci-u i v the relative positions shown in Figure :2'. The compression cap is now rotated until the graduation 36 thereon indi cating the desired maximum pressure of the within the inner tube registers with the indicating notch 4d when the nut is manipulated so as to lock this cap in its then position. Air is now pumped into the valve through the port 85,0pening and sleeve litlting the gasket 29 off its seat 30 against the pressure of the springSL, This air then passes through the chamber 11 port 17 and, lateral ports 18 into the valve stem. 'lhcse operations continue until the air in the inner tube has reached the predetermined pressure as indicated by the graduations on the compression cap. It the admission oi, the air into the tube is thereatter continued the pressure against the head 27 and the gasket 24 exceeds that of the spring which yields as a resultthereof. causing the sleeve 22 and all. of the parts connected therewith to move longitudinally within the valve body 10 and by so doing uncovering the port 15. Air now passes through this port 15 into the auxiliary chamber against the diaphragm 4L6 which is caused to vibrate by reason thereof and sound the alarm, thereby announcing that the maximum air pressure within the tire ha been exceeded. This continues until the air pressure within the tire has been re duced to the predetermined pressure when the spring it will return the sleeve to its original position and the gasket 24 to its seat d closing the port 15. The tension of the spring' 44, which determines the pres sure necessary to move the gasket 2% ott' its seal, is of course varied by manipulation of ti compression sleeve 83.
fith this mechanism, which is quite simple in construction and operation, it is impossible to inflate a tire with air beyond a very limited predetermined. amount without giving notice thereoi through the action of the diaphragm.
ii it-hin a limited range the detailed conration of the parts may be very materially id within my invention and I would tliere'lore have it understood I do not limit n vsell to the exact construction here in described but claim all that falls tairly thin the scope of the appended claim.
l'l'aving described my invention, what .l. claim as new and desire to secure by Letters Patent, is:
A tire alarm including a body having means to connect same to a tire valve stem and having an interiorly and exteriorly threaded part, a valve seat in the body; the body having an exhaust port, a sleeve havvalve thereon engaged with said seat, a spring pressed valve in the sleeve controlling the passage of air therethrough, a. can having an opening to admit air therein and having threaded engagement with the interior threads of said body part, a spring for holdingthe first named valve to its arranged within the cap and engaging the top or the latter. the outer end 01'? the sleeve projectinginto the inner end of the cap so as LU have an overlappingrelation thereto and the second named spring surrounding the sleeve and engaging the inner circumierc be oi. the can so that a continuous guide is provided for the second named spring by the overlapping oi? the sleeve and ap, a vompris ion cap threadedly engaged with the en rior threads of the body part, and means between the two caps for causing simultaneous-i n'iovcment thereof so that upon movement of the compression can the first named cap will move therewith to regulate the tension of the first named spring.
in testimony whereof. l have hereunlo a'l Tied my signature.
