Specification of lLetters Patent.

Patented May 14, 1912.

To all whom it may concern Be it known that I, WILLIAM HOWLIN, a subject of the King of Great Britain, residing at 17 Laura street, Newtown, near Sydney, in the State of New South Wales, Commonwealth of Australia, have invented certain new and useful Improvements in Apparatus for Automatically Opening and Closing Cocks, Valves, Switches, and the Like, of which the following is a specification.

This invention relates to improvements in apparatus such as that described in the specification of my prior Patent No. 861,854 of 30th July 1907 whereby cocks valves electric switches and the like are opened or closed at predetermined times by means of clock work.

The object of the present invention is to reduce the size and simplify the mechanism for eflecting the necessary movement of the cook or switch and at the same time render it more reliable in operation.

The invention comprises time setting means to be used in combination with clock work mechanism which supplies the power necessary to obtain movement of either of two levers which in turn at a predetermined time is caused to give a blow to one of two levers pivoted on a crank lever secured to the plug or stem of thecock or switch sufficient to instantly throw it to the on or off position as the case may be. But referring to the accompanying drawings I will describe the invention as applied to the.

lighting and extinguishing of an ordinary gas lamp provided with a pilot light or other igniting device.

Figure 1 is a perspective view of the apparatus inclosed in a dustproof casing with the front cover removed. Fig. 2 is a similar view with the casing and the dial removed.

nary eight day clock mechanism and to the framework 11 of same is atlixed a base plate 12 having fixed axles 13 for the respective gear wheels 14 and 15 provided with sliding sleeves 16. To these sleeves are adjustably connected the hour hands 17 and 18 respectively. The gear wheels 14 and 15 are in mesh with a leaf pinion 19 common to both, said pinion 19 being integral with the gear wheel 20 and rotatable on a fixed axle 21 secured to the base plate. The gear wheel 20meshes with a pinion 22 secured to the minute hand axle 23 which receives its motion in the usual manner.

The sleeves 16 of the gear wheels 14 and 15 have female threaded portions 24 for the male threaded end 25 of a key 26 for moving said sleeves outwardly to unmesh the gear wheels from pinion 19, and for adjusting the said wheels as hereinafter described. This outward movement of the sleeves is limited by a collar 9 fixed on axle 21, said collar being shown in Figs. 2, 3, 4 and 8, but omitted, for clearness of illustration, in Figs. 5, 6 and 7. These gear wheels are kept in mesh with the pinion 19 by the springs 27 taking against them and the back of the dial plate 28 which is affixed to the framework 11. They hate pins 29 and 30 which engage respectively with the projections 31 and 32 on depending levers 33 and 34 pivoted to the base plate 12, said levers being held in normal position by the coil springs 35 and agalnst stop pins 36 in the base plate 12. The lower ends of the levers 33 and 34 have angular extensions 37 and 38 respectively to engage with the levers 39 and 40 which are pivoted at 41 to the crank lever 42 affixed to the stem 43 of the gas cook 44 of the gas sup- P y p p 5- 46 is a burner having the usual pilot burner 47. y

The crank lever 42 has a sector groove 48 for the reception of a stop pin 49 secured to thegas cook 44. The levers 39 and 40 are substantially identical in shape but are reversely pivoted to the crank lever 42'. Each of said levers has a tail piece 50, and an enlarged head 51 ending in a shoulder 52 and an extension 53. The lever 34 has a pin 54 to engage with and depress the tail 50 of lever 39 but the projection 31 on the lever 33 being placed at the lower end thereof also acts to depress the tail 50 of lever 40.

The operation of the apparatus is as follows :The on or left hour hand is set by inserting the threaded end 25 of the key 26 in the sleeve 16 of the gear wheel 14 which is then drawn out of contact with the leaf pinion 19 thereby enabling it to be rotated to the hour marked on the dial at which it is desired to light up. The wheel 14 is then replaced in engagement with the pinion 19 and, preferably by means of the arm 56 on the key 26, the hour hand is moved back to the actual time of day. The off or right hour hand is now similarly set by means of the key to the hour at which the gas is to be turned off in the morning and the hand then turned back to the actual time. Then the pin 29 on the gear wheel 14 comes into contact with the projection 31 on the lever 33 (Fig. 5) it will press against same and gradually force said lever outwardly against the action of its spring 35. Just before the pin 29 passes over the point of projection 31 the lower end of the latter depresses the tail piece 50 of lever 40 and thereby unlocks the valve by raising the opposite arm to permit it to clear the angular extension 38 and fall under the head 51, (Fig. 6), the spring 35 pulling lever 3 1 against its stop pin 36. On the projection 31 being released (when the pin 29 passes same) the angular extension 37 on the lever 33 will, through the action of the spring, be caused to give a smart blow to the shoulder 52 on lever 39, and throw the crank lever 42 over and consequently the cock to the open position (Fig. 7 At the same time the extension 37 looks the cock in the open position until the closing of the cock is about to operate preferably half an hour before it is actually closed. The extinguishing of the light is a reverse movement to the above and takes place when the pin 30 on wheel 15 engages the projection 32 on lever 34:. As the wheel progresses in its rotation the pin pushes the projection 32 outward and on passing over same the angular extension 38 on the lever 34 will strike the shoulder 52 on the lever 10 and throw the crank lever over to the 01f position. Meanwhile the pin 54 depresses the tail piece 50 of lever 39 and raises the opposite end of that lever clear of the extension 37 on lever 33 so that said extension will not obstruct the free movement of the levers 39 and 40 when the crank lever is thrown over.

Having thus described my invention what I claim as new and desire to protect by Letters Patent is 1.
