- the primary gear 8 meshes with the pinion 9 rigid on the shaft 10 with the intermediate gear 11, which meshes with the pinion 12 rigidly mounted upon the shaft 13, which carries the minute hand 14.
- the third wheel 15 is rigidly attached to the pinion 12, and likewise a fourth wheel 16 is attached to a pinion 16a, in mesh with the third wheel 15, and revolves the escapement 17 by means of the fifth wheel 18, the pinion 18EL and the pinion 17?L on the escapement wheel shaft.
- the escapement wheel is controlled by the usual hair spring 19 and balance wheel 20, by means of the escapement lever 21, and a regulator 22 is provided upon the front plate ⁇ 3.
- the usual train of gears 23 is provided for revolving the hour hand 24, this train of gears consisting of the pinion 25 rigidly mounted upon the shaft 13, the wheel 26 pivotally mounted. on the stud 27 in the lfront plate 3, the pinion 26@L rigidly and concentrically attached to the wheel 26 and the wheel 28 in mesh with the pinion 26a pivotally mounted on the shaft 13 and having the hub 28awhich carries the hour h and 24.
- the spring 44 mounted on the shaft 45 with the primary gear 46, having a windingr mechanism 47.
- the shaft 45 has its forward ends squared, as at 48, and preferably of the same size and shape as the forward end 49 of the shaft 50 of the clock main spring 6, so that the same key may be used for winding either the clock main spring 6 or the valve operating main spring 44.
- the dial )late 51 is mounted on posts 51a.
- the shafts 45 and 50 extend through the dial plate, as do also the shaft 13, which carries the minute hand 14 and the hour hand 24 in front of the dial plate 51, and the cam shafts 31 and 32 which are provided with the thumb knobs 52 and 53 rigidly mounted thereon in front of the dial plate 51, for manually rotating the cams 29 and 30.
- crank shaft gear 54 In mesh with the primary gear 46 is the crank shaft gear 54, rigidly mounted upon the crank shaft 55.
- the primary gear 46 is also in mesh with the inion 56, which is rigidly attached to the first gear 57.
- the first gear 57 meshes with the pinion 58, which is rigidly attached to the second gear 59.
- the second gear meshes with the pinion 60, and the pinion 60 is rigidly attached to the third gear 61, which meshes with the pinion 62 on the controller shaft 63, which carries the controller 64, constituting a lcontrolling device for the valve operating spring 44, this controlling device being similar to that used with the striking mechanism of the ordinary clock, and which I do not claim, in itself, as my invention.
- crank shaft 55 is ournaled rearwardly in the strap 65, secured to the lower part of the rear plate 2, and forwardly in the upward extension 66 of the apron 67, which is secured to the lower part of the front plate 3, the crank shaft gear 54 being secured rigidly upon this crank shaft 55 between the front and rear plate by means of a set screw taking through the hub 68 of the crank shaft gear shaft 55, and the crank disk 70 is rotatably mounted on the crank shaft 55 to the rear of the ratchet wheel 69, with the pawl 71 in engagement with said ratchet wheel 69.
- the crank disk 7() has the radial slot 72 through which the wrist pin 73 is adjustably sccured to the crank disk 7 0;
- the valve crank 74 is secured to the stock 43 of the valve 42, and is also provided with a wrist-pin 75 similar to the wrist-pin 73, to both of which Wrist pins 73 and 75 is pivotally attached the connecting rod 76.
- the crank 74 has the radial slot 77 through which the wrist-pin 75 is adjustably secured, these adjustments being provided to adapt the valve operating mechanism to valves requin ing different degrees of turning of the valve stems in order to open or close them, this being necessary owing to the fact that the valve must always be opened or closed during onehalf of a revolution of the crank shaft 55, which always revolves in the same direction, in this case from left to right.
- the ratchet 69 and pawl 71 are provided to allow the crank disk 70 to be adjusted to the proper position relative to the crank 74, independently of the crank shaft 55, the continuous revolution of the crank shaft 55 in one direction allowing such an adjustment to be used.
- the crank 74 is provided with the shank 78, which is journaled in a bushing 79 in the rear plate 8O of the case 81.
- I ⁇ provide the sleeve 82 which is slipped onto the rearward part of the shank 78 and secured thereto by means of the set screw 83, thus permitting of adjustment longitudinally of the shank 78.
- I pivot the yoke 84 to the sleeve 82, which is adjustably secured to the stock 43 of the valve 42 b means of the straps 85 and.
- the sheave 88 is rigidly mounted on the crank shaft 55 in front of the apron 67, and is provided with the radial lug 89 on its periphery. Adjacent the sheave 88 at either side are the stops 90 and 91. These stops are pivoted on bushings 92 on the apron 67, being held thereon by means of the washers 93 and tap screws 94. These tap screws also serve to hold the apron 67 in place upon the front plate 3 by taking through the bushings 92 and the apron 67, and through the front plate 3 into the posts 4, as is illustrated in Fig. 3 of the drawing.
- the stop 90 at the right of the sheave 88, is pivoted with its engaging face upward and substantially in horizonta line with the center of the sheave 88, while the stop 91, at the left of the sheave 88, is pivoted with its engaging face downward and on the same horizontal line with the engaging face of the stop 90 at the right.
- the apron 67 is further secured to the front plate 3 by means of the screws 95 and 96, and the contractile spring 97 is also preferably secured to the screw 96 by one of its ends, and has its other end attached to the stop 91, near the outer end of said stop, through an opening 97a therein.
- a fence 98 is provided for the stop 91 and is adjustably secured to the front plate 3 by means of the screw 99.
- the stop 90 is also provided with a fence 100 adjustably secured to the front plate 3 by means of the screw 101, this screw 101 also preferably securing one end of the contractile spring 1.02 which at its other end is secured to the stop 90, near its outer end, through the opening 103. rl ⁇ he spiral springs attached to both of the stops 90 and 91 thus tend to draw the stops against the fences 100 and 98, respectively.
- the apron 67 is provided on itsv upper part with the lateral extensions 104 and 105, upon which the cam levers 106 and 107 are pivoted by means of the screws 108 and 109, respectively.
- cam lever 106 preferably has the end 110 inclined,- which is adapted to come within the arc of rotation of the stop 90 and limit the movement of its outer end away from the fence 100.
- the cam lever 107 has at its lower end the inwardly extending guard 111 which preferably has an inclined upper surface 112 adapted to come under the outer end of the stop 91 and limit its rotation away from the fence 98.
- the stops 90 and 91 being limited by the lower parts of the cam levers 106 and 107, respectively, they are thus adapted to prevent the sheave 88 from turning when its radial lug 89 engages either of them.
- the radial lug 89 thus engages one of the stops, the outer end of the stop will tend to rotate away from its fence and if the lower end of the cam lever be moved outward, the force of the spring 44 exerted through the intermediate parts upon the sheave 88 will cause the lug 89 by its engagement with the stop to rotate it against the tension of the contractile spring, allowing the lug 89 to pass.
- the cam lever 106 has at its upward end the ⁇ inwardly and downwardly extending finger 113 while the cam lever 107 has the inwardly and upwardly extending finger 114.
- These fingers 113, and 114 are adapted to bear against the peripheries of the cams 37 and 38 respectively, and said cams 37 and 38 are provided with the recesses 115 and 116, respectively, the inwardly downwardly extending iinger 113 and the inwardly upwardly extending finger 114 being so formed that any will enter the recesses 115 and 116,
- the cams 37 and 38 preferably rotate from left to right in the same direction as the hands of thel clock, and the recesses are so disposed that the peripheries of the cams describe an acute turn at lthe sides of the recesses where the fingers are adapted to enter said recesses. This formation of the cams permits the fingers to enter the recesses suddenly so that the lower ends of the cam levers will be thrown out to release the stops 90 or 91 quickly.
- the contractile springs 117 and 118 are secured to the cam levers 106 and 107, respectively, through openings 11.9 land 120, respectively, therein.
- the other ends of said contractile springs 117 and 118 are secured to the set ting arm 121 through the openings 122 and 123, respectively, therein near its upper end.
- This setting arm 121 is pivoted near its middle by means of the screw 124 on the bracket 125, said bracket being secured rigidly to the front plate 3.
- rPhe setting arm 121 has the slot 126 in its lower end over the hub 127 of the sheave88, and an engaging pin 128 is placed eccentrically in said hub 127 and engaging within the slot 126 in the setting arm.
- the setting bars 129 and 130 are pivoted to the setting arm 121 at its upper end and extend laterally to the cam levers 106 and 107 respectively, Where they have slots 131 and 132, respectively, in which engage the pivotal screws 133 and 134, respectively.
- the engaging pin 128, in the hub 127, is placed on the same side of the center of the sheave 88 as is the lu 89, and in radial alinement therewith, so t at when said lug 89 is being released from one of the stops, the upper end of the setting arm willbe thrown toward the side of the mechanism opposite to said stop.
- the slots in the setting bars are so proportioned that when the setting arm 121 has its upper end thus forced over, thel pin 133 or 134 on the cam lever 106 or 107, as the case maybe, will be en aged by the inner end of said slot so that t e upper end of thecam lever will be forced outward, removing the finger from the recess in the cam, leaving the cam free to rotate, and the lower end of said cam, lever will be forced inward, where said lower end will be adapted to engage and limit the movement of its respective sto thus limiting the crank shaft 55 to one-haf revolution at each release.
- the pointer on each thumb knob and 'the recess in the corresponding cam are given certain definite positions relative to eachother so that the cam lever controlled by said cam will kbe allowed to enter said recess and lrelease the sheave and its operatively connected valveoperating mechanism, instantaneously, when said oipter has reached a definite point on the 1a the pointer, maybe rotated with the cam inde endently of lthe cam gear, and' clock mec anism with which zit is in mesh, the pointer andthe cam may be thus manually set ⁇ at any desired position around the dial. However, vas soonpas the cam is set to such position, the frictional engagement of .the
- the time at which this cam will reach the point at which it releases the cam lever may be determined by setting the pointer the proper proportionate distance .around the -dial from the above mentioned definite point.
- each of the dials is labeled lto indicate the operation which will take place upon the release of the parts controlled by ⁇ their respective cams.
- An ordinary clock dial is also providedupon the dial plate 51 concentric'with the shaft 13, thus making it convenient for reference when setting the cams.
- the cam lever 186 will be held in such position that the stop 98 will stop ⁇ the sheave 88 when it has completed its one half revolution, and if the connecting rod 76 has been properly adjusted by means of the wrist pins 73 and 75 on the crank disk 70 and crank 74, respectively, the valve will have been opened during this one half revolution.
- lFig. 5 represents my invention when the 11 hours have almost elapsed, the cam 37 having Vbeen rotated by the clock mechanism to a point Where it is almost ready to release the camilever 106 ⁇ which controls the stop 90, and against which stop the lug 89 of the sheave 88 is now bearing.
- the opposite cam lever 107 is now forced outward away from its supporting cam by the setting bar 129, so that it thus controls the stop 91 ready to stop the sheave 88 when it has been released and has made its next one half revolution, closing the valve.
- the setting mechanism is setting the cam lever which has last been released, it also increases ⁇ the tension, and consequently the effectiveness, of the contractile spring which draws the opposite cam lever against its respective cam, during the time when it is desirable that said spring should be most effective in order to cause the cam lever to release the stop quickly.
- an opening 14'1 is provided in the rear plate 80, and a plate 142 is removably secured over said opening and provided with a gasket 143.
- gaskets are provided to make the case 81 dust and moisture proof.
- a starting mechanism is preferably provided for the balance wheel of the clock mechanism, which consists of a wing 144 pivotally mounted in f the arm 145 and rotatable, by means of the thumb knob 146, to engage said balance wheel, this starting mechanism being desirable when the clock mechanism is permanently secured, rendering it inconvenient, should the clock stop, to start it by the ordinary method of shaking it slightly.

Preferably my invention is constructed as follows:
A frame 1 comprising a rear plate 2, front plate 3, and posts 4, forms a support and bearings for an ordinary clock mechanism 5 preferably having the main spring 6 with its winding mechanism 7 and primary gear 8. The primary gear 8 meshes with the pinion 9 rigid on the shaft 10 with the intermediate gear 11, which meshes with the pinion 12 rigidly mounted upon the shaft 13, which carries the minute hand 14. The third wheel 15 is rigidly attached to the pinion 12, and likewise a fourth wheel 16 is attached to a pinion 16a, in mesh with the third wheel 15, and revolves the escapement 17 by means of the fifth wheel 18, the pinion 18EL and the pinion 17?L on the escapement wheel shaft. The escapement wheel is controlled by the usual hair spring 19 and balance wheel 20, by means of the escapement lever 21, and a regulator 22 is provided upon the front plate`3. Also the usual train of gears 23 is provided for revolving the hour hand 24, this train of gears consisting of the pinion 25 rigidly mounted upon the shaft 13, the wheel 26 pivotally mounted. on the stud 27 in the lfront plate 3, the pinion 26@L rigidly and concentrically attached to the wheel 26 and the wheel 28 in mesh with the pinion 26a pivotally mounted on the shaft 13 and having the hub 28awhich carries the hour h and 24.
The above description of the clock mechanism is given only for the purpose of facilitating the succeeding references to the parts thereof and I do not wish to be understood as claiming said clock in itself, as my invention, any of the usual clock mechanisms being adapted for use in combination with my invention. This use is accomplished by providing the right and left cam gears 29 and 30 which mesh with the pinion`26a, and, being provided with twice as many teeth as has the wheel 2S which revolves the hour hand 24, these cam gears 29 and 30 will be revolved only once in twenty four hours instead of twice in that time as is the hour hand 24. The cam gears 29 and 30 are rotatably mounted on the hollow cam shafts 31 and 32,
which are provided with flat springs 33 and l 34 rigidly mounted thereon and held against the faces of the cam gears 29 and 30 between the inner collars 35 and 36, which are preferably integral with the cam shafts 31 and 32, and the cams 37 and 38 which are rigidly secured on the cam shafts 31 and 32 by means of the set screws 39 and 40. It will thus be seen that while the cam gears 29 and 30 are revolved by the clock mechanism through the pinion 26a, the cams 37 and 38 are revolved by the cam gears 29 and 30 through the frictional contact of the springs 33 and 34 with the faces of the cam gears 29 and 30. This frictional contact allows the cams to be rotated manually, independently of the clock mechanism. rlhe hollow cam shafts 31 and 32 are journaled on the cam studs 41, which are supported by the front plate 3.
For opening and closing the valve which is represented at 42, and which has the stock 43, I prefer to use as a motor, the spring 44 mounted on the shaft 45 with the primary gear 46, having a windingr mechanism 47. The shaft 45 has its forward ends squared, as at 48, and preferably of the same size and shape as the forward end 49 of the shaft 50 of the clock main spring 6, so that the same key may be used for winding either the clock main spring 6 or the valve operating main spring 44. The dial )late 51 is mounted on posts 51a. The shafts 45 and 50 extend through the dial plate, as do also the shaft 13, which carries the minute hand 14 and the hour hand 24 in front of the dial plate 51, and the cam shafts 31 and 32 which are provided with the thumb knobs 52 and 53 rigidly mounted thereon in front of the dial plate 51, for manually rotating the cams 29 and 30.
In mesh with the primary gear 46 is the crank shaft gear 54, rigidly mounted upon the crank shaft 55. The primary gear 46 is also in mesh with the inion 56, which is rigidly attached to the first gear 57. The first gear 57 meshes with the pinion 58, which is rigidly attached to the second gear 59. The second gear meshes with the pinion 60, and the pinion 60 is rigidly attached to the third gear 61, which meshes with the pinion 62 on the controller shaft 63, which carries the controller 64, constituting a lcontrolling device for the valve operating spring 44, this controlling device being similar to that used with the striking mechanism of the ordinary clock, and which I do not claim, in itself, as my invention.
The crank shaft 55 is ournaled rearwardly in the strap 65, secured to the lower part of the rear plate 2, and forwardly in the upward extension 66 of the apron 67, which is secured to the lower part of the front plate 3, the crank shaft gear 54 being secured rigidly upon this crank shaft 55 between the front and rear plate by means of a set screw taking through the hub 68 of the crank shaft gear shaft 55, and the crank disk 70 is rotatably mounted on the crank shaft 55 to the rear of the ratchet wheel 69, with the pawl 71 in engagement with said ratchet wheel 69. The crank disk 7() has the radial slot 72 through which the wrist pin 73 is adjustably sccured to the crank disk 7 0; The valve crank 74 is secured to the stock 43 of the valve 42, and is also provided with a wrist-pin 75 similar to the wrist-pin 73, to both of which Wrist pins 73 and 75 is pivotally attached the connecting rod 76. The crank 74 has the radial slot 77 through which the wrist-pin 75 is adjustably secured, these adjustments being provided to adapt the valve operating mechanism to valves requin ing different degrees of turning of the valve stems in order to open or close them, this being necessary owing to the fact that the valve must always be opened or closed during onehalf of a revolution of the crank shaft 55, which always revolves in the same direction, in this case from left to right. The ratchet 69 and pawl 71 are provided to allow the crank disk 70 to be adjusted to the proper position relative to the crank 74, independently of the crank shaft 55, the continuous revolution of the crank shaft 55 in one direction allowing such an adjustment to be used. The crank 74 is provided with the shank 78, which is journaled in a bushing 79 in the rear plate 8O of the case 81. To allow of the proper accuracy of adjustment between' the shank 78 and the stock 43 of the valve 42, which is to be operated, I `provide the sleeve 82 which is slipped onto the rearward part of the shank 78 and secured thereto by means of the set screw 83, thus permitting of adjustment longitudinally of the shank 78. To allow for slight 'variations of alinement between the valve 42 and the case 81, I pivot the yoke 84 to the sleeve 82, which is adjustably secured to the stock 43 of the valve 42 b means of the straps 85 and. bolts 86, the stock 43 preferably having the recesses 87, which admit the bolts 86 and prevent total displacement of the parts while allowing of a slight slidable adjustment depending upon the amount of clearance allowed.
The sheave 88 is rigidly mounted on the crank shaft 55 in front of the apron 67, and is provided with the radial lug 89 on its periphery. Adjacent the sheave 88 at either side are the stops 90 and 91. These stops are pivoted on bushings 92 on the apron 67, being held thereon by means of the washers 93 and tap screws 94. These tap screws also serve to hold the apron 67 in place upon the front plate 3 by taking through the bushings 92 and the apron 67, and through the front plate 3 into the posts 4, as is illustrated in Fig. 3 of the drawing. The stop 90, at the right of the sheave 88, is pivoted with its engaging face upward and substantially in horizonta line with the center of the sheave 88, while the stop 91, at the left of the sheave 88, is pivoted with its engaging face downward and on the same horizontal line with the engaging face of the stop 90 at the right. The apron 67 is further secured to the front plate 3 by means of the screws 95 and 96, and the contractile spring 97 is also preferably secured to the screw 96 by one of its ends, and has its other end attached to the stop 91, near the outer end of said stop, through an opening 97a therein. A fence 98 is provided for the stop 91 and is adjustably secured to the front plate 3 by means of the screw 99. The stop 90 is also provided with a fence 100 adjustably secured to the front plate 3 by means of the screw 101, this screw 101 also preferably securing one end of the contractile spring 1.02 which at its other end is secured to the stop 90, near its outer end, through the opening 103. rl`he spiral springs attached to both of the stops 90 and 91 thus tend to draw the stops against the fences 100 and 98, respectively.
The apron 67 is provided on itsv upper part with the lateral extensions 104 and 105, upon which the cam levers 106 and 107 are pivoted by means of the screws 108 and 109, respectively. rl`he cam lever 106 preferably has the end 110 inclined,- which is adapted to come within the arc of rotation of the stop 90 and limit the movement of its outer end away from the fence 100. The cam lever 107 has at its lower end the inwardly extending guard 111 which preferably has an inclined upper surface 112 adapted to come under the outer end of the stop 91 and limit its rotation away from the fence 98. The movement of the stops 90 and 91 being limited by the lower parts of the cam levers 106 and 107, respectively, they are thus adapted to prevent the sheave 88 from turning when its radial lug 89 engages either of them. When the radial lug 89 thus engages one of the stops, the outer end of the stop will tend to rotate away from its fence and if the lower end of the cam lever be moved outward, the force of the spring 44 exerted through the intermediate parts upon the sheave 88 will cause the lug 89 by its engagement with the stop to rotate it against the tension of the contractile spring, allowing the lug 89 to pass.
The cam lever 106 has at its upward end the` inwardly and downwardly extending finger 113 while the cam lever 107 has the inwardly and upwardly extending finger 114. These fingers 113, and 114 are adapted to bear against the peripheries of the cams 37 and 38 respectively, and said cams 37 and 38 are provided with the recesses 115 and 116, respectively, the inwardly downwardly extending iinger 113 and the inwardly upwardly extending finger 114 being so formed that any will enter the recesses 115 and 116,
respectively, without interruption, when the cams 37 and 38, respectively, have rotated to the proper position. The cams 37 and 38 preferably rotate from left to right in the same direction as the hands of thel clock, and the recesses are so disposed that the peripheries of the cams describe an acute turn at lthe sides of the recesses where the fingers are adapted to enter said recesses. This formation of the cams permits the fingers to enter the recesses suddenly so that the lower ends of the cam levers will be thrown out to release the stops 90 or 91 quickly.
For holding the fingers in enga ement with the periphery of the-cams norma ly, the contractile springs 117 and 118 are secured to the cam levers 106 and 107, respectively, through openings 11.9 land 120, respectively, therein. The other ends of said contractile springs 117 and 118 are secured to the set ting arm 121 through the openings 122 and 123, respectively, therein near its upper end. This setting arm 121 is pivoted near its middle by means of the screw 124 on the bracket 125, said bracket being secured rigidly to the front plate 3. rPhe setting arm 121 has the slot 126 in its lower end over the hub 127 of the sheave88, and an engaging pin 128 is placed eccentrically in said hub 127 and engaging within the slot 126 in the setting arm. The setting bars 129 and 130 are pivoted to the setting arm 121 at its upper end and extend laterally to the cam levers 106 and 107 respectively, Where they have slots 131 and 132, respectively, in which engage the pivotal screws 133 and 134, respectively. The engaging pin 128, in the hub 127, is placed on the same side of the center of the sheave 88 as is the lu 89, and in radial alinement therewith, so t at when said lug 89 is being released from one of the stops, the upper end of the setting arm willbe thrown toward the side of the mechanism opposite to said stop. The slots in the setting bars are so proportioned that when the setting arm 121 has its upper end thus forced over, thel pin 133 or 134 on the cam lever 106 or 107, as the case maybe, will be en aged by the inner end of said slot so that t e upper end of thecam lever will be forced outward, removing the finger from the recess in the cam, leaving the cam free to rotate, and the lower end of said cam, lever will be forced inward, where said lower end will be adapted to engage and limit the movement of its respective sto thus limiting the crank shaft 55 to one-haf revolution at each release.
lt will be seen that by adjusting the crank disk 70 by means of the ratchet, the wrist pin 73 may be brought to such a position relative to the lug 89 on the sheave 88 that during one half revolution the crank 74 will be rotated, to close the valve 42, while during the other half revolution it will be rotated in the opposite direction to open the valve 42.
ilo
Since the lug 89, being released by the action of the cam, ycam levers and stop on one side, is stopped by the stop on the opposite side, due to the relative lpositionsof said stop and its corresponding cam lever, which is held in position by the cam on such opposite side, .it will be seen that the opening and closing of the valve 42 may be controlled according to the osition of the cams. As these cams revo ve once in .each twenty four hours, due to `their operative connection with the clock mechanism, ythey will, if undisturbed, regularly control the positions of the ycam levers and stops and, consequently, 'the rotation of the'crank shaft 55 and the opening and closing of the valve 42 which is in operative-connection therewith.
The thumb knobs 52 and 53 yare provided with :the pointers 135 and 136 rigidly attached thereto, and the dial `platel is provided with the dials 7137 and 138 concentric with the cam shafts 3,1 and 32, respectively. These dials 137 and 138 are divided-and subdivided to indicate the hours and `fractions of hours in the day. The pointer on each thumb knob and 'the recess in the corresponding cam are given certain definite positions relative to eachother so that the cam lever controlled by said cam will kbe allowed to enter said recess and lrelease the sheave and its operatively connected valveoperating mechanism, instantaneously, when said oipter has reached a definite point on the 1a the pointer, maybe rotated with the cam inde endently of lthe cam gear, and' clock mec anism with which zit is in mesh, the pointer andthe cam may be thus manually set `at any desired position around the dial. However, vas soonpas the cam is set to such position, the frictional engagement of .the
flat spring with the face of the cam gear will cause said cam to be rotated `uniformly by the clock mechanism. Therefore, the time at which this cam will reach the point at which it releases the cam lever may be determined by setting the pointer the proper proportionate distance .around the -dial from the above mentioned definite point.
As illustrated, I .prefer to subdivide each of' the divisions indicating the twenty four hours of the day into four parts and to number the graduations indicating the hours from 1 to 24 and from right to `left around the dials. The pointers should be turned in the opposite direction as indicated by the arrows on the dials, and each of the dials is labeled lto indicate the operation which will take place upon the release of the parts controlled by `their respective cams. An ordinary clock dial is also providedupon the dial plate 51 concentric'with the shaft 13, thus making it convenient for reference when setting the cams.
As illustrated in Figf4, my improved au- As the thumb knob., .and consequentlyA tomatic time valve is in the act of opening, the cam lever 107 lhaving entered the recess 116, thus releasing the stop 91 and allowing the sheave 83 to turn past it and the pointer 136 having reached the graduation 24 on the dial 133. The clock hands indicate the time as seven oclock. Then supposing'that itis desired that the valve should close at six oclock, or eleven hours thereafter, the pointer 135 on the-opposite dial is turned in the direction of the arrow to the graduation '11 thereon. The cam lever 186 will be held in such position that the stop 98 will stop `the sheave 88 when it has completed its one half revolution, and if the connecting rod 76 has been properly adjusted by means of the wrist pins 73 and 75 on the crank disk 70 and crank 74, respectively, the valve will have been opened during this one half revolution. lFig. 5 represents my invention when the 11 hours have almost elapsed, the cam 37 having Vbeen rotated by the clock mechanism to a point Where it is almost ready to release the camilever 106 `which controls the stop 90, and against which stop the lug 89 of the sheave 88 is now bearing. 1t will be noted that the opposite cam lever 107 is now forced outward away from its supporting cam by the setting bar 129, so that it thus controls the stop 91 ready to stop the sheave 88 when it has been released and has made its next one half revolution, closing the valve. While the setting mechanism is setting the cam lever which has last been released, it also increases `the tension, and consequently the effectiveness, of the contractile spring which draws the opposite cam lever against its respective cam, during the time when it is desirable that said spring should be most effective in order to cause the cam lever to release the stop quickly.
vFrom the above description it will be seen that once the times of opening and closing of the valves every day have been decided, it is only necessary to set the pointers around the dials as above described, and to keep the clock main spring and valve operating main spring wound, after which my improved automatic time valve will continue to open and close regularly at the appointed times every day without further attention. My invention thus is adaptable for use where it is desired to open and close any valve at regularly appointed times, it being especially adaptable for use with gas lamps for street lighting in which case the lamps would be supplied with pilot burners, the construction and arrangement herein shown and described being provided with this end in view. As shown, the case 81, inclosing the mechanism, is provided with gaskets 139 in its joints with its rear plate 30 and its door 140. To allow of convenience in adjusting the Wrist pin 73, an opening 14'1 is provided in the rear plate 80, and a plate 142 is removably secured over said opening and provided with a gasket 143. These gaskets are provided to make the case 81 dust and moisture proof. A starting mechanism is preferably provided for the balance wheel of the clock mechanism, which consists of a wing 144 pivotally mounted in f the arm 145 and rotatable, by means of the thumb knob 146, to engage said balance wheel, this starting mechanism being desirable when the clock mechanism is permanently secured, rendering it inconvenient, should the clock stop, to start it by the ordinary method of shaking it slightly.
While the construction herein shown and described is adaptable for daily automatic operation and more particularly for use with gas lights, I do not wish to be understood as limiting myself to it, but
