To all whom it may concern:
Be it known that I, FRANK L. WOLrE,-a citizen of the United States, and a resident of Medford, in the count State of Massachusetts, have invented certain new and useful Improvements in Thistle-Valves, of which the vfollowing is a specification.' j I M invention relates to whistle valves and its o ject is to provide means for automatically o rating such valvesand automatically recor mg the passa e of steam through. the `outlet chamber of t e valve into the whistle bell, and the time of such passage.
It isan improvement upon m invention described in Letters Patent f o. 787,422 dated April 18, 1905; and also u on -another invention for which I have app led for Letters Patent by an application filed December 1, 1905 Serial No. 289 878.
` It is illustrated byA the accompanyin drawings in which- Figure 1 is a vertical section of the whistle valve. Fig. 2 is a plan view'of the clock. Fig. 3 is an elevationof the electro magnet on line 3-3, of Fig. 2.
Similar characters refer tok similar parts a throughout the several drawings. y
1 is the Whistle bell.
2 is the whistle bowl threaded-at its base for'attachment to the steam, or any other fluid reservoir and divided intotwo communicating chambers, the inlet chamber 3 and the outlet chamber 4. Seated in chamber 3 is the valve 5 O erated by the piston 6 1ocated-in the cylinder 7 laterall projected from the Outlet chamber 4, and having pas- 8 leading to the open air and other passages 9 leading to the cylinder 10 laterally projected from inlet chamber 3. In the mlet chamber 3 is also seated the spring actuated valve 11 with its stem 12 arranged in the cylinder 10 which ma be operated mechanically by the lever 13 Vulcrumed at 14 on the outer wall of cylinder 7.
Projected from the inlet chamber 3 is the cylinder 15 with a reduced inner portion 16, a larger middle portion 17 with passages 18 leading therefrom to the inlet chamber 3 and a still larger outer portion 19 which constitutes the cylinder proper with the passage 20 leading therefrom to the inlet c amber 3. In the outer portion 19 of the cylinder 15 is located the balanced piston 21 having the.

' with the middle portion 17 ofthe cylinder 15.
lThis pistonY 21 e loosely the outer portion 19 of the cylm er 15 thereb rmit the' steam from the inlet cham pe tmg round itI and p beco steam'. The valve 11 as a second valve stem 23 which asses through and is inv sliding contact wit the inner portion 16 of the the piston stem 22 and iston 21,
r3tosurlandis furnished on its outer end wit the adjustabledmt. 30. On the valve stem l23 is arrange t e -houllders on. ti'ildlirldvell and on the cyliner 5.
Projected from the cylinder 15 is the diahragmlchamber 26 with a passagev leading rom one to the other, through which passage extends the valve stem 28 of the spring actuated va1ve 29 seated in said cylinder 15.
Passages 24 lead from the dia hr chamber 26 to the open air. In t is 'aphragm chamber are arranged the diaphragm 31 and the spring 32. The diaphragm 31 rests upony the annular shoulder 33 in contact with the outer end of the valve stem 28, and is held in. place by the threaded Projected from'v the Outlet chamber-4 is the da hragm chamber 42 With the assage 43 balanced in said 25 confined between rin 34. lgrojected from the diaphragm .chamber 26 lea Aing thereto from said outlet c amber 4.
In the passage 43 isseated the spring actuated leak valve 44. On an annular shoulder 45 of the diaphra m chamber 42 rests the diaphragm 46 'he d in place b ring 47 which engages the t readed wall of the diaphragm chamber 42. The threaded hub 48 enga es the said threaded Wall of the diaphragm c amber acting as a jam nut on the threaded ring 47. Extending through this hub 48, and in free sliding contact therewith, is the spring actuated plunger 49 With its inner end 1n contact With said diaphragm 46, and having mounted in its outer end the the threaded successively engage the spring 56 normally 1in contact with the adjustable contact screw l57 mounted on the insulator fiber block- 58 l'mounted in said case, to which-block the wires 39, A39a lead, the wire 39 being connected by the bindin nut 59 with said spring 56, a'nd the wire 39gbeing connected by the binding nut 59al with the adjustable screw 57 whose inner end normally contacts with the 56. The wires 53, 538L connect with t e e ectro magnet 64 disposed within the clock case with its spring actuated armature 65 having an arm 66 pivoted to the arm 67 iXed to-theshaft 68 mounted in the clock case, and having fixed to its up er end the pencil arm 69 carrying the pencii) 7 O andthe arm 71 carrying a pencil platform 72. On the arbor 54 is mounted the rotary chart support 73 on which rests the chart 74 held in p ace by the washer 75 and thumb nut 76. This chart rests also upon the annular support 77.
This device, which may be used for recording the o eration of the whistle valve under any con itions, is particularly useful upon vessels where whistles are required to be sounded at certain intervals, for instance during a fog; and the chart in the drawing is arran ed to rotate once in four hours, as just state or during the usual watch on vessels. Of course any fluid other than steam may be used with the whistle valve.
The operation of the device is as follows: The whistle valve being attached t0 a steam boiler, steam fills the inlet chamber 3, the passages 18 and 20, and the cylinder 15, pressin equally on the inner and outer suraces o the iston 21, the valves 5, 11, and 29 are seate the valve stem 23 has a very slight longitudinal play so as to insure the seating of the valve 11. The valve stem 28, the diaphragm 31 and armature stem 38 are in contact. When the electric circuit 39 39a is closed the spring 56, being in contact with the screw 57, the armature forces the valve 29 from its seat, compressing the spring 32 and extending the sprin 38, and permitting steam to escape from cy inder 15 to the open air. The balanced piston 21 is forced by the steam outwardly, unseating the valve l1 and compressing 'the spl-ring 25.. The steam escapes into the cy der 10 thence through the passa es 9 into that art of the cylinder 7 above t e piston 6. he pressure of the steam upon the istonbeing racticall `the same as that of t e steam in t e inlet c amber, and the surface of the piston belng greater than the surface of the valve 5,t'lis" pressure Will force the valve from its seat and allow steam to escape from the inlet chamber into the outlet chamber 4 and thence upward through the whistle bowl 2 into the whistle ing the 'contact s rings 51, 51 into contact,
closing the electrlc circuit 53, 53", operating the pencil arm 69, and moving the pencil upon the rotating chart 74. l
The gear 55 on the arbor 54 carries the spring 56 out of contact with the screw 57, t ereby opening the circuit 39, 39'L and the valves 29 and 11 return to their seats, forced thereto by the steam pressure assisted by the springs 25, 32 and 38. The steam remain ing in the cylinder 10, passages 9 and space above the piston `6 in cylinder 7 instantly escapes through the passages 8 into the open air, thus removing the pressure from the iston 6 and allowing the valve 5 to be force to its seat by the pressure of steam in the inlet chamber 3 5 thus cutting off the, supply of steam to the outlet chamber 4, to the whistle bowl and to the diaphragm chamber 42, thus permitting the sprmg actuated plunger to move inwardl and separate the s rings 51 and 51a there y opening the circult 53, 53 permitting the armature 65 to return the pencil 70 to its starting point; and so the operation is repeated and the whistle sounded as the teeth of the gear 55 successively make and break the contact of the spring 56 with the screw 57 as just described. The circuit 39, 39a ma be opened and closed by pressing a button i desired.
