WILLIAM If. GRAFTON, OF ST. LOUIS, MISSOURI, ASSIGNOR, BY TILE-SHE ASSIGNMENTS, TO UNITED STATES AUTOIIIOBILE ACCESSORIES MANUFACTURIN'G COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI.
WHISTLE VALVE.
Specification of Letters Patent. Pg fggnt ed A 111 113,522
Application filed May 17, 1920. Serial No. 881,960.
To aZZ whom it may concern Be it known that I, VVILLIAM L. GRAFTON, a citizen of the United States, residing at St. Louis and State of Missouri, have invented certain new and useful Improvements in Whistle Valves, of which the following is a specification, reference being had therein to the accompanying drawing.
My invention relates to improvements in whistle-valves and has for its object to provide a valve particularly adapted for use in actuating a whistle blown by heated gases, the valve being so constructed as to embody a single spring and to isolate that spring from the heated gaseous medium, to the end of preserving the temper oi" the spring and ensuring the accurate action of the valve. Another object of my invention is to minimize the number of parts and weight of metal composing the valve.
In the drawings Fig. 1 is a vertical mid-sectional view of a structure embodying my invention.
Fig. 2 is a transverse sectional view taken through the whistle-body on the line i;--2 of F 1, and looking toward the valve.
In the base 3 the terminal i or" the vertical valve-housing 2a is screw seated as shown in Fig. l, the terminal it having a tapered bore 5 to register with the conoidal valvehead 6, having a screw-driver slot '7 for use in grinding the valve-head 6 into accurate titting in the bore 5. The head 6 is integral with the valve-stem 8, which stem has a bearing collar 9 and washer 10 secured in place by the cotter- pins 12 and 11 respectively. Loosely fitting about the upper end of the stem 8 is a coiled-spring 13, whose upper end engages the Washer 10 and whose lower end rests upon the top of the arch 16, which is open at its sides for purposes of coolness, and which is slotted to receive the bell-crank 17 and its pivot 18. at the top of the arch 16 is the bore 14, of substantially larger diameter than the valve-stem 8; while the bore 15 is of such diameter as to fit the stem 8 snugly. The valve is actuated by the contact of the lever 17 with the collar 9. The horizontal nipple 19 receives the neck 20 of the whistle 21, whose -form is indicated in the drawings, and which is cut away to form the lip 22, against which the whistle-actuating gases are discharged through the slot 23, the emission of the gases being controlled by the action of the bell-crank lever 17 upon the collar 9.
By means of the construction shown the spring 13 is so far removed from the heated gases passing through the valve that its temper is unaftected thereby. The construction embodies few parts and each of those parts is readily removable for purposes or" replacement or repair.
Having thus described my invention, what l'claim as new and desire to have secured to me by the grant of Letters Pat ent, is
In combination, a vertical valvehousing; a horizontal nipple thereon; a whistle mounted on said nipple; an arch surmounting said valve-housing; a valve-stem extending vertically through said housing and arch; a coiled-spring mounted about said valve-stem above said arch; and an actuating lever mounted in said arch and engaging with said valve-stem.
In testimony whereof I hereunto afiix my signature.
WILLIAM L. GRAFTON.
