To all whom it may concern.-
Be it known that 1, JOHN H. BICKFORD, of Salem, county of Essex, State of Massachusetts, have invented an Improvement in Oontrolling Devices for Electric Generating Systems, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.
This invention has for its object to construct a controlling device for an electric generating system which may be located at a distant point and operated by an unskilled person to start the electric generating system in operation.
The invention consists in a starting device adapted to be manipulated by the operator to perform a number of successive acts, whereby the electric generating system is started.
An electric generating system to which it is proposed to apply the starting device embodying this invention comprises, essentially, a vaporizer for liquid hydrocarbon,adapted to be heated by a current from a storage battery or other source, a valve for controlling the admission of liquid hydrocarbon to said vaporizer, which is operated automatically by a thermal device, which is in turn operated by the heat of the vaporizer whenever said vaporizer is heated to a sufficient temperature to vaporize the liquid hydrocarbon, a valve which controls the admission of gas (vaporized liquid hydrocarbon) to the burner of a power generating and converting apparatus, a controlling device for regulating the delivery of gas to correspond to the output of a dynamo which is adapted to be operated by said power generating and converting apparatus, substantially as shown in my Letters Patent No. 656,165, an automatically-operated igniting device for said burner, means for cutting out the resistance in the shuntfield of said dynamo, means for closing the dynamo-circuit containing the translating devices, means for disconnecting the storage battery when the dynamo has been brought into action, means for connecting the vaporizer and hydrocarbon-controlling device in circuit with the dynamo when the storage battery has been cut off, and means for connecting the storage battery in circuit with the translating devices to operate them when the dynamo is at rest.
In accordance with this invention the starting device is provided with a main actuatinglever which is arranged to be moved in one directiont'. 6., forward-to perform the successive acts required in starting the electric generating system and to be returned to its normal positiont'. 6., backward-to restore all the parts to their normal position. As herein shown, when the main actuating-lever is moved forward it will first operate a switch to close a circuit including a storage battery and the heating-coil of a vaporizer, and as soon as said switch has been closed said main actuating-lever will be locked in fixed position against movement in either direction until the vaporizer has been heated and also until the valve has been automatically opened by said vaporizer, by which the liquid hydrocarbonis admitted to the vaporizer. Then said main actuating-lever is released in order that it may be again moved onward, and as said main actuating-lever is moved onward another switch will be operated by it, by which a circuit is closed, including an electromagnetic device, by which a valve is opened which controls the supply of gas to the burner of the power generating and converting apparatus, and as soon as said switch has been operated said starting-lever is again locked in fixed position until steam has been generated in the steam generator, which formsa part of said power generating and converting apparatus, and when the steam has been generated and reaches acertain pressure said main actuating-lever will be again released in order that it may be again moved onward, and as said main actuating-lever is again moved onward it operates suitable means whereby the storage battery is disconnected and a dynamo is brought into action and the dynamo-circuit, including the translating devices, closed. A locking device is also preferably provided for the main actuating-lever, which engages and holds it in fixed position while the dynamo is building up before the dynamo circuit, including the translating devices, is closed, which will be operated in case said main actuating-lever is moved too quickly, said locking device being thereafter operated automatically to disengage said main actuating-lever at the proper time. At or about the same time that the main actuating-lever brings the dynamo into action it also connects the vaporizer and hydrocarbon controlling device with the dynamo-circuit in order that said devices may be operated by the dynamo when the storage battery is cutout. The main actuating-lever is prevented from backward movementat all times during its forward movement. \Vhen it is desired to stop the electric generating apparatus, the main actuatinglever is returned to its starting-point and all of the parts restored to their normal positions and the storage battery connected in circuit with the translating devices to operate them when the dynamo is disconnected.
Figure 1 shows in front elevation a controlling device for electric generating systems embodying this invention. Fig. 2is an enlarged view, as compared with Fig. 1, of the apparatus, the front plate being removed. Fig. 3 is a sectional detail of the main actuating-leverand means for operatingit. Fig. e is adetailof the switch which is operated bythe main actuating-lever to open the gas-cock and ignite the burner. Fig. 5 is a detail of vthe switch which is operated by the main actuating-lever to disconnect the storage battery from the vaporizer and controlling device for the liquid hydrocarbon. Figs. 6, 7, and 8 are details of the locking device for the main actuating-lever, which holds said lever in fixed position while the steam is being generated and raised to a predetermined pressure. Fig. 9 is a detail of the means for manipulating the main actuatingdever at the end of its forward stroke, whereby it shall return in a different plane. Figs. 10 and 11 are details of the device for opening the valve controlling the admission of gas to the burner. Fig. 12 is a diagram of the apparatus and its circuits.
The main actuating-lever of the starting device is herein shown as an arm a, secured to a sleeve a mounted on a spindle a, which has its hearings in the back and front plates a a of a box or case, and said main actuating-lever and other parts with which it cooperates are contained in said box or case, and said main actuatingJever is herein shown as adapted to be moved to and fro a part of a circle in a plane in parallelism with the back and front plates of the box and to successively perform the several acts required for starting the electric generating apparatus as it travels in one direction and to restore all the parts to their normal positions as it returns. One end of the sleeve 0 projects through the front plate a of the box or case and has secured to it a hand-wheel a, by which it is turned to in turn positively move the main actuating-lever in one direction, and to said projecting end of the sleeve a a pointer a is also secured, which as the sleeve is turned travels over a dial or index on the indicating the position of the main actuatinglever.
The hand-wheel a as herein shown, serves as and constitutes the operating device for the starting device; yet so far as my invention is concerned I do not desire to limitit to the employment of an operating device of this description. I prefer to turn the main actuating-lever in one direction by means of the hand-Wheel 00 to start the electric generating apparatus and to return said main actuating-lever to its starting-point automatically, and to provide for thus automatically returning said main actuating-lever a restoring-spring is employed, which, as herein shown, is connected to the spindle a.
The sleeve Q has at its lower end a slot at, which receives a pin a, projecting laterally from the spindle a, and by means of this connection the spindle a is turned on its axis by the hand-wheel a". The slot at is made long enough for the sleeve (1, to turn inde' pendent of the spindle for a short distance for purposes to be hereinafter described and to then engage and turn the spindle.
A restoring-spring a is attached at one end to the spindle a and at the other end to a fixed point, and when the spindle is turned in one direction by the hand-wheel a said spring will be wound up, so as to act to turn the spindle in the opposite way when permitted so to do. It is desirable that the spindle a shall be turned slowly in both directions. Hence a retarding device is provided for it, consisting, as herein shown, of an escape-wheel a, secured to the spindle a,which is engaged by a suitable pallet a secured to a shaft bearing a fan a When the arm a has been moved by the hand-wheel a from its starting-point to the position it will occupy when the electric generating apparatus is started, it is necessary to holdit in such position during the time said apparatus is in operation, and to accomplish this resultmeans are provided for locking the main actuating-lever at the end of its forward stroke. As herein shown, the arm Ct has attached to it a dog e which is adapted to engage a detent-arm e pivoted at a and forming one arm of a bell-crank lever, the other arm (1 of which is arrangedto be operated both automatically and manually. The detent-arm (e is disposed so as to be engaged by said dog a when the arm a has been moved its full stroke for starting the complete apparatus to thereby lock said arm a in such position with the restoring-spring of under tension, and said arm a will remain in such position until the detent-arm a is operated to release it. To operate the detent-arm c4 and thereby release the arm a, a suitable prop a is located beneath said arm a, which is pivoted at a to a suitable bracket, and a finger-piece a is attached to said prop, which serves as a means for moving it on its pivot ICC IIO
to thereby lift the arm a and move the detent-arm a out of engagement with the dog a. The finger-piece c4 projects through a slot in the front plate of the box, so as to be readily accessible. Additional means are furthermore provided for moving said detentarm a automatically at a predetermined time, which, as herein shown, consists of a clock-train 6, having one of its wheels, as b,
provided with a laterallyprojecting stud, which as said wheel revolves engages the arm (615 and moves the detent-arm at out of engagement with the dog a. The clock-train will be of any usual construction and will be set so as to have its wheel b operate to lift the arm a at any predetermined time.
It is important to prevent any backward movement of the arm a when traveling forward to start the apparatus, and to accomplish this result said arm a has attached to it a pawl c, which engages ratchet-teeth 0, formed on a semicircular bar 0 secured to the back plate a The pawl 0 may be made as a gravitating pawl, which is pivoted to the under side of the arm a. During the travel of the arm Ct forward from its starting-point to the point where it becomes engaged by the detent-arm (L13 the pawl 0 will continuously engage said ratchet-teeth 0; but on the return movement of said arm a the pawl 0 will be lifted out of engagement with said teeth, so that said arm may be returned by means of the restoring-spring (6 moving slowly as it returns by reason of the escapement mechanism which is connected with it. To lift the pawl 0 out of engagement with the ratchetteeth d u ring the homeward travel of the arm a, said arm a is divided in two parts, which are hinged together at and disposed in alinement, one of said parts, as a being a forward extension of the other, and said forward extension L1 is normally held in the same plane occupied by the part to which it is attached by means of a flat spring cfilwhich is attached to the arm at one side of the hinge, its free end bearing upon said forward extension a 'When the arm a travels forward, its forward extension a will occupy its normal plane, as shown in Fig. 3; but when said arm returns homeward said forward extension at will be lifted high enough for 'the pawl c to disengage the ratchet-teeth c. To positivelyinsure the extension at of the arm a occupying its normal plane during the entire forward movement of the arm and to lift said extension and hold it elevated during the entire homeward movement of the arm, a rail or bar cl is provided, which is made semicircular in form and which is supported in elevated position upon the back plate a by a number of stands d, and said elevated. rail 61 is so located relative to the arm a as to be engaged by a friction-roll a borne by the forward extension at of said arm. As the arm a travels forward its extension a passes along the under side of the rail (Z, and as said arm travels homeward its extension a passes along the top of said rail, being held by said rail in position for the pawl c to engage the ratchet-teeth during the forward movement of the arm and also held by said rail with its pawl out of engagement with the ratchet-teeth during the homeward movement of the arm. An inclined portion (Z is provided at one end of the rail (Z, (see Fig. 9,) which is pivoted to said rail (Z at d or is otherwise supported, and said inclined portion is made as a continuation of the rail (1 and is held down in its inclined position by means of a spring (2 (see Fig. 2,) attached to the back plate a the free end of which bears upon a lug d projecting from said pivoted inclined portion (P. The pivoted inclined portion d when thus held down by the spring cl occupies a position crossing the path of movement of the extension d of the arm when said arm is traveling forward and is passing along the under side of the rail d, so that as it passes by or beyond the end of said rail (Z it will engage said pivoted inclined portion d and lift it, after which said pivoted inclined portion (P will fall back to its normal position. On the return movement of said arm a the extension a first engages said inclined portion (P, and by it is lifted into position to engage the top of the rail d, and as said arm a returns said extension will follow along the top of said rail d until it arrives at its starting-point, when it slips off said rail d and resumes its normal position, and it will be observed that as the arm a thus travels homeward the pawl will be held out of engagement with the ratchetteeth.
The main actuating-lever a has attached to its extension at, but insulated therefrom, a pair of contact-pens e e, which are connected together by a cross-piece 9 yet said contactpens and cross-piece may all be made of one piece, and said contact-pens project laterally from the lever and are located a short distance apart and in parallelism, and they are adapted to engage two semicircular plates 0 c as the lever travels forward. The semicircular plates 0 and c are both secured to the back plate a in parallelism and concentric to the spindle a, and they are insulated from each other bysaid back plate and are electrically connected by circuit-wires with a storage batieryB or equivalent appara tusas, for instance, a wire 2 (see Fig. 11) leads from the plate 0 to a wire 3, which leads to a wire 4, which leads to one pole of the battery B, and a wire 5 leads from the plate to a wire 6, which leads to a wire 7, connected to a coil f, and a wire 8 leads from said coilftoa wire 9, which is connected to the other pole of said batteryB. Thus while the contact-pens c and e are in engagement with the semicircular plates 0 e the circuit thus described will be closed. The coilf contains within it a coil of pipe f, (see dotted lines, Fig. 12,) which is connected at one end to a conducting-pipe f and at the other end to a delivery-pipe f and said coil of pipe f is designedto receive liquid hydrocarbon from the pipe f and be heated by the coilf to thereby vaporize said liquid hydrocarbon in order that it may be delivered as a vapor by the pipef The coilftherefore serves as a heating-coil for the vaporizer.
A valve f is contained in the conductingpipe f which is adapted to be automatically opened in order that the liquid hydrocarbon may be delivered to the vaporizer, and to accomplish this result a thermal device f is provided on the vaporizer, which is adapted to be operated by the heat of the coilf, and said thermal device is herein shown as a thermometer having a pair of electric contacts adapted to be closed by the mercury rising in the tube, yet of course any other form of thermal device may be employed. One of the contacts of the thermal device is connected by a circuit-wire 10 to the wire 8, and theother contact is connected by a circuit-wire 12 to the coilf of a solenoid, and a wire 13 leads from said solenoid to an electromagnetf and a wire 14 leads from said electromagnet f to the wire 6. The loop-circuit 10 12 13 14: is thus electrically connected with the battery B, so that the electromagnetic devices included therein will be operated whenever the circuit-wires 10 and 12 are closed by the thermal device. The contacts are disposed so that said circuit-wires 10 and 12 will be closed when the temperature of the vaporizer has reached a temperature sufficient to vaporize the liquid hydrocarbon and not before. The armature of the solenoid f is connected with the valve f so that said valve will be operated by said armature, being opened whenever said armature is attracted and closed whenever said armature is retracted. It will thus be observed that when the main actuating-lever is moved forward and its contactpens e 6 close the battery-circuit the coil f will begin to heat the vaporizer, and as soon as the temperature has reached a point suflicient to vaporize the liquid hydrocarbon the thermal device will act and close the loop-circuit, including the solenoid f and the valve f will be opened, admitting liquid hydrocarbon to the vaporizer. Then the main actuating-lever has been moved forward far enough for its contact-pens e e to close on the plates 0 6 a locking device is brought into action, which prevents further onward movement of said main actuating-lever until the vaporizer has operated. The locking device herein shown for accomplishing this result consists of an electromagnet f included in the loop-circuit containing the solenoid f, and which is operated by the thermal device closing the circuit-wires 10 and 12, and the armature f of said electromagnet f bears a projection or stud j, which when the armature is in its retracted position obstructs the path of movement of the starting-lever by engaging a stud e thereon. When,however, the armaturef is attracted, as it will be when the loop-circuit is closed, then said main actuating-lever will be released. As soon as the main actuating-lever is released it may be moved onward, and as it is thus moved it next operates suitable means whereby a valve is operated which controls the supply of hydrocarbon to the burner of the power generating and converting apparatus.
The valve which controls the supply of hydrocarbon to the power generating and converting apparatus is herein represented as contained 'in the valve-case g and having a stem g, which when turned in one or the other direction opens and closes the way. The valvecase g is connected with the delivery-pipe f from the vaporizer and with the pipe g which is connected with the burner. (Not shown.) The valve-stem g has secured to it a disk g which is formed or provided with a projection g, which is normally engaged by the hooked end of flll'flilll or lever g formed on or attached to the armature g of a solenoid g and as the armature of said solenoid is attracted the disk will be turned to in turn partially rotate the valve'stem g and open the way. The disk g is constructed in the manner shown, so that the valve-stem g may be further rotated by other means to be described independently of said solenoid g A mutilated pinion g is also secured to said valve-stem g, the teeth of which are adapted to be engaged by a rack-bar g attached to the armature g of a solenoid g, substantially as shown in my Patent No. 656,165, before referred to, and said rack-baris designed to operate said pinion g and thereby further rotate the valve-stem 9 independently of the solenoid 9 In practice the solenoid is energized first and the valve-stem g turned to open the way, and afterward the solenoid is energized and the solenoid 9 cut out, and while said solenoid g is energized the way will be opened more or less, according to the output of the dynamo. As soon as the solenoid g is cut out its armature returns into position to again engage the projection g. A weighted arm 1 is attached to the valve-stem, which is employed as a means of turning said valve-stem to close the way, when the solenoid is out out and its armature g retracts and the pinion g returns to a position whereby the mutilated portion thereof will disengage the rack-bar.
In Fig. 10 the parts are represented in the position they will occupy when the way is closed, and in Fig. 11 said parts are represented in the position they will occupy when the way is open by means of the solenoid j and is in the position to be further opened by the solenoid g The solenoid g is included ICO in a loop-circuit comprising a circuit-wire 20,
which leads from the coil of the solenoid to the wire 3 and thence to the battery by wire 4, and also a circuit-wire 21, which leads from the solenoid to one point 22 of a switch, and a wire 23, which leads from the other point 24; of said switch to the wire 9 and thence to the battery, and said loop-circuit is operated by the switch-arm 25, cooperating with said points 22 and 2e, and whenever said switch is closed the loop-circuit will be closed and the solenoid operated.
The switch-arm is herein shown (see Fig. 4) as pivoted at h to the back board a and having a short arm 7; projecting from it, the extremity of which is loosely connected by a link 71 with one end of a lever 7L3, pivoted at 7r at a point substantially midway its length, said lever being bent at substantially right angles and disposed to project through an opening in the back board, so as to occupy a position in the path of movement of the stud (L on the main actuating-lever. The switch is normally held open and the lever 7L normally held in position to be engaged by the stud a by means of a spring 71 connected toa short arm M, which forms the extension of the lever 7L3, but when said stud a engages said lever h and depresses it the switch-arm 25 is thrown into engagement with the points 22 2e and the loop-circuit closed. The switch 22 24B 25 is made on the plan of an ordinaryjump-switch for obvious reasons and will be instantly opened whenever the lever h is released. As soon as the loop-circuit containing the solenoid g is closed and the Valve g opened the hydrocarbon passes to the burner, which is contained in the shell or case t' of a steam-generator t of any suitable construction, and to ignite it automatically an igniting device is provided, which, as herein shown, consists of a coil j, of platinum wire orequivalent material, which is connected in a loop-circuit comprising a circuit-wire 30, which leads from one end of the coilj to the wire 21, and the circuit-wire 31, which leads from the other end of the coil j to the wire 20, and as said circuit- wires 20 and 21 are connected with the battery B and operated by the switch 22 24 25 it will be seen that when the loop-circuit comprising said wires 20 and 21 is closed by said switch said igniting device will also be operated. It is designed and intended that the main act uatinglever shall act to hold said switch 22 24 25 closed while the steam is being generated in the steam-generator v1, and to provide for the accomplishment of this result a locking device is provided for holding said main actuating-lever, and, as herein shown, said looking device consists of a projection 7c, (see Fig. 6,) rising from the piston-like disk is, contained in a cylinder 73, said disk being normally held in its elevated position by means of a spring k and adapted to be pressed down against the action of said spring by the pressure of steam in the steam-generator. The projection 79 is located in the path of movement of the stud a on the main actuatinglever, so as to be engaged by said main actuating-lever when it occupies a position whereby it is holding the lever 7L3 pressed down. The steam is admitted to the cylinder through a pipe M, which is connected to a pipe is, leading from the steam-generator. Thus it will be seen that as soon as the steampressure has reached a predetermined point the piston-like disk 7; in the cylinder 7&2 will be pressed down and the projection 70 removed from the path of movement of the main actuating-lever, and said main actuating-1ever being thus released is free to be moved onward in its course. As the main actuating-lever is moved onward in its course the switch-lever 71 would immediately rise and open the switch it means were not pro- Vided for preventing such action, and if the switch-lever. 7L3 should open the circuit at this particular time the valve 9 would be closed and the gas shut off from the burner, because the solenoid 9 has not at this time been included in the circuit which is designed to operate it. Hence means are provided for holding said switch-lever 7L3 down and the switch closed after the main actuating-lever has passed by the locking device 70 and until such time as the solenoid g shall have been duly energized, and,'as herein shown, the projection It has formed on it a spiral groove 75 which receives a pin 70, secured to and projectinginwardly from the top wall of the cylinder 73, so that as said projection 70 descends it will be turned on its axis a partial revolution for purposes to be explained. The projection It has also formed upon or secured to it a laterally-projecting bent pin 10 which is adapted to cooperate with or engage a lateral projection k on the switch-lever 7?. In operation the switchlever its will be depressed and will be held down by the main actuating-lever while said lever is bearing against the pin is. Then as said pin 7t" descends to release the main actuating-lever it turns on its axis, so that the lateral projecting pin k will pass over the top of the projection 7d, and thereby hold said switch-lever h depressed positively until such time as the steam is shut ofit from the cylinder. If, however, the steam should be admitted to the cylinder while the switch-lever h is in its elevated position, the projection is will descend and turn on its axis while descending, and in such case the bent pin will pass beneath the lateral projection 73 on the switch-lever 7L3. In the pipe 79 leading from the pipe 76 is a valve 70 of any suitable description, which is so disposed as to be engaged and operated by a stud a on the main actuating-lever at the proper time and to close said valve to thereby shut otif the steam from the cylinder is", and when the steam is thus shut off the piston will be raised by the spring contained in said cylinder, and the switch-lever 71. will consequently be released. t
m is intended to represent a steam-engine of anysuitable construction which is operated by the steam from the steam-generator t", and said engine is adapted to operate a dynamo n, which also may be of any suitable construction. The steam having been generated lOQ and brought to the required pressure, the steam-engine started, and the dynamo also started, the next act to be performed by the main actuating-lever a is to bring the dynamo into action. The dynamo n, as herein shown, is a common form of compound-wound machine, and to bring it properly into action the resistance of its shunt field-circuit must be cut out.
p represents a rheostat contact-arm, which is rigidly secured to the spindle a, and said contact-arm is adapted to move in a plane in parallelism with the main actuating-lever a and to pass over and successively engage a number of contacts 19 on the back board a said contacts forming a part of the rheostat or resistance which is included in the shunt field-circuit of the dynamo n. The rheostat contact-arm p is connected with the main actuating-lever a by means of aspiral spring 19 yet said spring is not provided for the purpose of moving said contact-arm, as said arm is rigidly connected with the spindle a. As the main actuating-levera is moved from its starting-point the spring 19 will be more or less extended, as it is weaker than the restoring-spring a and the contact-arm p will therefore remain at rest until said main actuating-lever has been moved far enough for the sleeve a to engage the pin projecting laterally from the spindle a, and it is notintended that said contact-arm shall start until the steam has been generated. \Vith the spring p thus extended the contact-arm p is then moved by the main actuating-lever positively engaging and turning the spindle, and as it moves it passes over the several contacts 19' and cuts out the resistances in the shunt field-circuit of the dynamo. The relative positions of the main actuating-lever and contact-arm will remain the same even when the main actuating-lever has completed its forward stroke and is engaged by the detent-arm a, and at such time the contact-arm will bear against the stopp The springp therefore subserve s no function during the forward stroke of the main actuating-lever. As the main actuating-lever completes its forward stroke a blade a carried by it, engages the switch-plates q, s, and t, and being then locked by thedetent-arm a will remain in engagement with said switch-plates during the operation of the apparatus. As soon as the main actuating-lever a is released by the proper operation of the detent-arm a, it being at such time unrestrained, the spring 19 which has been held in extended condition, will immediately draw it toward the contactarm 19, thereby instantly opening the several switches and preventing the formation of arcs. The spring 19 therefore subserves, essentially, the function of an actuating-spring for the lever 66 when the latter is serving as a switch-lever. As the main actuating-levera travels onward from the stop the contactarm 13 moves with it; but before said main ac tuating-lever arrives in position for its blade a to engage the switch-plates q, s, and t it must pass by or over a stop M, which is herein shown as an electromagnet u, included in the shunt field-circuit of the dynamo, having the stop or projection LL on its armature U and said stop or projection a normally occupies a position in the path of movement of said stud a on said lever a to engage said stop, and thereby check the onward progress of the lever. The contact-arm p is presumed to move slowly, owing to the retarding device which is connected with the spindle a, and the dynamo is supposed to generate current up to the normal pressure for which it isdesigned by the time the main actuating-lever a arrives at the stop it, and if such is the case then the electromagnet u will be energized and the armature attracted and the projection it removed from the path of movement of the stud (1 but if the dynamo should not build up in time,which is sometimes the case, then the stud (1- will engage the projection to and the main actuating-lever and contactarm 19 will be held at rest until said projection u has been removed.
The shunt field-circuitof the dynamois herein represented as the circuit-wire 40,1eading from the resistances to the point 41 on the contact-brush n of the dynamo, and the circuit-wire 42, leading to the point 43 on the contact-brush n of the dynamo, and the electromagnet u is included in said circuit-wire 42, and it will be seen that while the contactarm 19 is in engagement with the contacts 19 said shunt fieldcircuit will be closed. During the time the main actuating-lever a is moving step by step to perform the several acts required to start the steam-generator, steam-engine, and dynamo the storage batteryB is employed for the purpose of supplying the necessary current to do the work; but aft-er the dynamo has been brought into action the said storage battery Bis cut out just before or as the dynamo-circuit is closed, after which time the vaporizer and controlling device for regulating the supply of hydrocarbon to the burner will be operated by the dynamo. As herein shown, the storage battery Bis cutout just as the dynamo-circuit is closedt'. a, just as the blade 0. on the main actuating-lever closes on the switch-plates q,
s, and 1fand to accomplish this result the contact-pens e e are removed from engagement with the contact-strips 0 6 The contact-strips c e terminate at the proper point relative to the position of the switch-plates q, s, and t for the accomplishment of this result, yet means are provided for preventing an are being drawn when said contact-pens e e leave said strips. The contact-strip e terminates a short distance back of the contact-strip c and an independent contact-strip w is provided, which is located so as to present a continuation of said contact-strip 6 yet leave a gap between said strips to and a and as the main actuating-lever travels along the contact-pen 2' will continue in engagement with the contact-strip 0 while the contact-pen e I will leave the strip e cross the gap, and pass on to the strip to, and finally the two contactpens e e will disengage said contact-strips c and to at or about the same time and just as the blade a engages the switch-plates q, s, and If. The contact-strip w is attached to the back board a and insulated from the othercontact-strips. A switch is provided which is adapted to close an electrical connection between said contact-strips e and to while the pen 6 is crossing the gap between said strips e and 10, which afterward operates and breaks said electrical connection while the pen c is on the strip 21:. The switch 10' consists of a pivoted lever located in the path of movement of the stud a on the main actuating-leverand is properly disposed to be operated by said stud to close the circuit while the pen 6 is crossing the gap between the strips 6 and w. The pivoted lever of the switch 1r (see Fig. 5) has an arm depending from it, which is connected by a spring 20 with the back board, said spring serving to normally hold the lever in its elevated position, and said lever also has depending from it an arm tr, the lower end of which is loosely connected with one end of a lever 10 pivoted at 21' to an arm U17, and said lever'w carries a blade 10 which is adapted to engage switch-plates w w from which the circuit-wires lead, one circuit-wire, as to, leading to the contact-strip e and the other circuit-wire, as 10 leading to thecontact-stripw. Whenever this switch is closed by the main actuating-lever, the contact-strips e and w will be electrically connected together. When the blade (L50 on the main actuating-lever is brought into engagement with the switch-plates q, s, and i, said switch-plates will be electrically connected together, and the dynamo-circuit, together with the circuit including the translating devices, and also the circuit including the controlling device for regulating the supply of hydrocarbon to the burner, and also the circuit including the vaporizer, will be closed. From the plate a circuit-wire leads, which is connected to the solenoid of the controlling device for the hydrocarbon, and a wire 51 leads from said solenoid to the dynamo at 41. From the plate .9 a wire 52 leads, which is connected to one of the wires 53, including the translating devices, and a wire 55 leads from the other wire 56 of the circuit including the translating devices, which leads to the dynamo at 43 and forms the compound coil of the dynamo. Thus it will be seen that when said plates 3 and 25 are electrically connected together the dynamo-circuit including the translating devices and also including the controlling device for the hydrocarbon is closed. From the plate q a wire 60 leads, which is connected to the wire 6 and by the wires 7 and 8 is connected to wire 58, which is connected with the wire 56, so that the vaporizer is included in circuit to be operated by said dynamo n.
When the main actuating-lever it returns to its normal position or starting-point, which it will do automatically when released by means of the restoring-spring a" as its extremity is lifted, so that the pawl is held out of engagement with the ratchet-teeth c, the contact-pens e 6 will also be held out of engagement with the contact-strips, and the said stud a will pass over freely the several stops and switch-levers. WVhen the main actuating-lever is in its normal position and the dynamo n at rest, it is intended that the translating devices 54: shall be connected in circuit with the storage battery B, and to ac complish this result a switch-arm 1 is pivotally connected at y to a projection on the rheostat contact-arm, and the extremity of said switch-arm is connected by a spring 3 with a bent arm y projecting from said rheostat contact-arm, so that said switch-arm 1 will be operated by movement of said rheostat contact-arm. The switch-arm 1 engages a pair of switch-plates if 3 A circuit-wire leads from the switch-plate 1 to the wire 53, and a wire 71 leads from the switch-plate p to the wire 4, and when the switch-arm 3 is closed the translating devices 54 will be included in the battery-circuit as follows: 13, wires at 71, switch-plate 3 arm y, switchplate 11 wires '70 53 56 5S 9 to battery. Thus it will be seen that normally the battery-circuit is closed by said switch-arm y; butwhen the main actuating-lever a has been moved sufficiently for the rheostat-arm p to close on the first contact p of the resistance the said switch-arm y is disengaged from the switch-plates 1 1 and said battery-circuit opened at this point, although the batterycircuit will have been previously closed by the contact-pens e e engaging the contactstrips 6 0 as previously described.
