GAS-CONTROLLER, ELECTRIC TIME-SWITCH, AND OTHER TIMING- DEVICE.

To aZZ 'whom t may concern:

Be it known that we, ALBERT HoRsTMANN, GUs'rAv Orro HENRY HORSTMANN, ERNST HERMANN HonsTMANN, SIDNEY AnoLrH HonsTMANN, and WILLIAM THOMSON EDGAR, subjects of the King of Great Britain and Ireland, and residents of'Bath, county of Somerset, England, have invented certain new and useful Improvements in Gas-Controllers, Electric Time-Switches, and other Timing Devices, of which the following is a specification.

The present invention relates to certain new and useful improvements in time switches'of that type which are actuated by' clock work or the like and serve to open and close a switch or cock at predetermined reference times.

The object of the invention is the provision of a device ofthis character which can be readily mountedin position, which can be accurately and quickly yadjusted to open and close a switch or cock at the desired times, and which is positive and reliable in its operation.

Wit-h these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, is-ftofbe had to the following de-V script-ion` and accompanying drawings, in which .f

rels employed in the modilicat-ionillustrated in Fig. 4.

to in the followin description and indicated Corresponding and like parts are referred in all theviews o the drawings by the vsame reference characters.

Referring to Fig. 1 of the drawing, the reference characters a and b indicate two spaced plates having a barrel c arranged between the same, the said barrel being mounted upon a winding arbor @Z which projects outwardly beyond the plate a where it terminates in a square head adapted to 'be engaged in the usual manner by a key when winding the spring within the barrel c. The barrel c is `formed with the usual gear wheel c which constitutes one yof the gears of an ordinary clock work ortrain of gears controlled by an escapement, the said wheel being regulated to make one complete revolution every .twenty-four hours or other predetermined period of time. It will also be observed that the barrel c is formed with a centrally disposed bosse which surrounds the winding 'arbor and is formed with a bearing e fitting within the opening within the plate a; The outer end of the boss is reduced as indicated at e2 and fric upon switch or cock as-may be desired. The in vner end of each of the discharge arms Z2 is formed with a disk Z havingia central opening Z3 therein to receive aboss m which projects outwardly from the dial plate. Dis'hed spring washers 7', such as areshown in detail in Figs-7 and 7 mayy beinterposed be tween the disks Z of the 'various discharge arms, and a clamping member n is employed for forcing the disks Z against the dial plate to lock the discharge arms rigidly in an adjusted position. This clamping member is shown in detail in Figs. 5 and 5, and co1nprises a lever n2 having one end thereof bifurcated as indicated at n', the arms of the 'bifurcation terminating in laterally ofset cam portions n3v which are pivotally connected to opposite sides of the boss m of the dial plate by suitable members such as the screws n4.

When the lever n2 is swung outwardly away from the dial plate, the thinner portions of the cam members aaare brought into engagement with the disks Z of the discharge arms so lasto release the said discharge arms and admit of the said arms being turned to any desired position upon the dial plate. In this position of the locking member fn., however, the dished spring washers 1' would still frictionally engage the disks vZ so as to take up any looseness and hold the discharge arms against accidental displacement. When the lever n2 is swung inwardly toward the dial plate g, the

,thicker portions of the cam members ai* are brought into engagement with the disks Z of the discharge arms so as to force the said disks tightly against the dial plate and hold the discharge arms securely in an adjusted position. Attention may also be directed to the fact that the cam portions n of the locking member are formed with the wings a5 which project radially from the winding arbor b and are arranged in a plane at right i angles lto the face ofthe dial plate when the upon the single arbor da, the said barrels belockingl member is in operative position. These wings n.5 are for convenience in setting the time dial g in relation to the exterior index-hand c.

In the operation of the device, the clock work mechanism will cause the dial plate g to make one revolution in every twentyfour hours or other predetermined period of time, and as the outer ends Z4 of thedis- `charge levers Zzvcome successively into contact with the switch actuating members arranged in the path thereof, the switch or cock may be opened and' closed at certain times determined by the position of the discharge arms with relation to the dial.

A slight modification is shown in Fig. 2 in which the outer reduced end e2 of the boss e projecting from the barrel c is en- ,ga-ged4 by a split sleeve 7'2 projecting rearwardly from a dial plate h, which carries the discharge arms (not shown).

A vfurther modification is shown in Fig. 4' in which the clock work mechanism isl formed with a series 'of barrels mounted ing designated bythe characters c, c3, c4, and c5. The usual springs would be arranged within these barrels, the inner end of each of the springs being ,secured to a hook 'e4 upon the boss of the adjacent barrel, while the outer end is secured-to the periphery of the barrel. With this construction, it will be apparent that by applying the key to the varm projecting arbor the various springs can be wound up 1n the usual manner so as to admlt of the clock work running for a much longer time than would be possible where only one -sprmg was employed.

Having thus described the invention, what we claim as new and desire to secureby Letters Patent, is I l. A switch actuating deviceincluding a dial plate provided upon one side thereof with an axially projecting sleeve adapted to frictionally engage a rotary member to support the dial plate in position, a discharging arm carried by the dial plate, a cam for locking the arm to the dial,.and dial setting means carried by the cam.

5. In a switch actuating device, the combination of a dial plate mounted to have a rotary movement and formed with an axial projection, a discharge arm mounted up'on the dial plate, the outer end of the discharge beyond the dial plate while the inner end of the discharge arm is formed with an opening loosely receiving the projection, and a locking lever having a bifurcated end which is pivoted upon the projection, theI arms of the bifurcation being formed with cams adapted to clamp the discharge arm against the dial plate.

6. In a switch'aetuating device, the combination of a dial plate mounted to have a roa discharge arm mounted upon y holding the discharge arm in posigrips carried by the locking means for setfting'the dial.

In a switch actuating device, the combij nation of an arbor, a Wheel mounted upon the arbor and formed With a boss surrounding the arbor, a dial plate provided upon one side thereof with a sleeve 'adapted to frictionally engage the boss of the Wheel and upon the opposite side thereof with a boss which also surrounds the arbor, a discharge arm mounted upon the dial plate and formed With an opening receiving the boss upon, the vdial plate, and a locking lever formed with a bifurcated end which is pivotally mounted upon the boss, the arms of the bifurcation being provided with cams adapted to clamp the discharge arm against the dial plate.4

8. A switch actuating device comprising a rotatable dial provided with a boss, discharging arms mounted on the boss, and a cam pivotally mounted on said boss for locking the arms to the dial and provided with means whereby the dial may be manually set.. v

9. A switch actuating device comprising a dial, discharging arms, a cam for locking the arms againstmovement relative to the dial, and Wings carried by said cam and forming hand grips to permit the dial to be manually set.
