TIME LIGHTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 663,852, dated December 18, 1900.

Application filed April 25, 1900. Berial No. 14,342. (No model.)

To call whom it may concern.-

Be it known that I, WALTER W. BOLLEN, a citizen of the United States, residing at Red Oak, in the county of Montgomery and State of Iowa, have invented a new and useful Automatic Igniting Device, of which the following is a specification.

My present invention relates to an automatic igniting device, and has for its object the production of a simple apparatus controlled by time mechanism and designed to ignite fuel in a stove or furnace or issuing from a gas-jet or otherwise employed for the purpose of maintaining combustion for light ing, heating, or other purposes.

To this end the invention comprehends the igniting mechanism associated with a trip mechanism of any suitable variety-as, for instance, an ordinary alarm-clock, which latter may serve the dual function of tripping the igniter and sounding an alarm-as, for instance, for the purpose of arousing the person, in advance of whose arising the apparatus is designed to start a fire or make a light;

The invention comprehends the employment of a casing or framework containing a suitable motor operating an oscillatory matchcarrying arm and designed to be tripped for the purpose of bringing a match carried by the match-carrying arm into frictional contact with the ignition-surface, and subordinate objects of the invention are to provide the motor with a governor which will prevent too violent actuation of the match-carrying arm, to provide adjustable trip mechanism by means of which the motor may be arranged for employment in connection with various styles of tim e-pieces, and to construct the match-holder at the free end of the matchcarrying arm in a manner to insure the exertion of an elfective pressure upon the match as it is drawn across the ignition-surface for the purpose of igniting'by friction the fulminate head at the extremity of the match-stem.

The invention further consists in the construction and arrangement hereinafter to be described, illustrated in the accompanying drawings, and succinctly defined in the appended claims.

In the accompanying drawings, Figure l is a fragmentary perspective view of a stove, illustrating the application of my igniter.

Fig. 2 is a perspective View of my ignition apparatus complete, the match-carrying arm being in full lines in its set position and the intermediate and tripped positions of said arm being indicated in dotted lines. Fig. 3 is a sectional elevation through the motor, showing the timepiece in elevation. Fig. at is a top plan View of the motor and its immediately connecterl parts with the topframeplate removed. Fig. 5 is a longitudinal sec tion through the outer end of the matchcarrying arm, illustrating the construction of the match-holder. Fig. 6 is a transverse sectional view of the subjectanatter of Fig. 5, and Fig. 7 is a detail view illustrating the application of the trip-lever to the arbor of an ordinary clock.

Referring to the numerals of reference employed to designate corresponding parts in the several views, 1 indicates a base-plate upon which the apparatus is mounted and which is designed to be supported in proximity to the fuel to be ignited in any suitable manner-as, for instance, by resting it, as illustrated by Fig. 1, upon the hearth of an ordinary stove. The motor or actuating mechanism is mounted in a suitable frame composed, for instance, of parallel horizontal top and bottom plates 3 and 4, spaced by cornerposts at" and screwed or otherwise secured upon the base 1, as by screws passing through the bottom plate 4. The main post of the m0- tor (indicated by the numeral 5) is mounted in suitable bearings in the frame-plates and is provided at its upper end, above the plate 3, with an enlarged head 6, integral with or otherwise fixed to the post and provided with a horizontal diametrical opening 7 for the reception of one end of the match-carrying shaft 8, adjustably retained in the head, as bya setscrew 9, piercing the wall of the head and bearing against the arm. The match-carrying arm 8 is of sufficient length to cause its outer end to describe an arc of sufficient extent to present the head of a match 10 to an ignition-surface 11 provided on the base 1 and to convey the lighted match into effective proximity to the fuel. (Indicated in Fig. 1 by the numeral 12.) The ignition-surface may be formed upon the base in any suitable manner but I prefer to secure thereto a con'vexlycurved block 13, covered by a strip of sandpaper or like abrasive material 14. The motor for actuating the post to oscillate the match-carrying arm preferably comprises a stout motor-spring 15, having one end fixed to the frame-as, for instance, to one of the that when the match-carrying arm 8 is swung to itsset position, as indicated in full lines in Fig. 2, the motor-spring 15 will be wound and the ratchet-wheel 18 and post will rotate independently of the gear-wheel16 and its pawl 17. Thus when the match-carrying arm is swung to one extreme limit of its movement its motor-spring is wound to compensate for the slight. unwinding of the spring which takes place when the device is tripped and the arm swung under the impulse of the spring to ignite the match and present it to the inflammable material. The violent shock or jar which would otherwise be incident to the violent movement of the arm and its sudden stopping as it is presented to the stop 19, projecting from the base, is prevented by the employment of a governor or retarding device. This governor may be of any suitable form, but is preferably a rotary fan 20, carried by a motor or fan shaft 21, upon which is also mounted a notched controlling-wheel 22, designed to be engaged and retained against rotation by a trip-pawl 23,

medially pivoted upon a post 24, suitably carried bythe frame and having its end opposite the wheel 22 connected with the lower end of what may be termed the trip-lever 25 by an intermediate link 26. 27 indicates a spring connected at one end to the trip-pawl 23 and at its opposite end to a fixed part-as, for instance, to one post 4to normally retain the pawl in engagement with the notched wheel 22.

In order to render the governor 20 efiective to cushion the movement of the match-carrying arm, it must rotate at a high rate of speed, as the resistance opposed by it would otherwise be immaterial. I therefore interpose between the arbor or shaft 21 and the post 5 a suitable train of gearing, comprising, for instance, an arbor 28, provided with a pinion 29, meshing with the gear-wheel 16 upon the post 5, and also provided with a gear-wheel 30, meshing with a pinion 31, mounted upon an arbor 32, to which is also fixed a gear-wheel 33,.meshing with a pinion 34 upon the post 21. This train of speed-gearing will communicate a high rate of speed to the fan-shaft 21 when the match-carrying arm 8 is oscil lated to effect the ignition of the match; but, as stated, the movement of the arm in the opposite direction to reset it for another operation will not cause the actuation of the gearing, inasmuch as the ratchet 18 will rotate idly necessary to effectively retain the motor inactive, and very slight movement of the triplever is necessary in order to release the fanshaft to permit the motor-spring to swing the match-carrying arm.

.One of the important features of my present invention is the specific construction of the trip-lever 25 to adapt it for use in connection with various forms of time mechanism. This construction of the trip-lever comprehends an angularly-adjustable end 35, pivotally connected to the lever proper, as indicated at 36, and provided with an adjusting or set screw 37, movable within a transverse slot 38, so that the adjustable end 35 of said lever may be deflected to one side or the other and secured in fixed relation to the lever proper by tightening the screw 37.

In the drawings I have illustrated an ordinary alarm-clock 39 in connection with my ignition apparatus, and I have shown an ec-' centric offset or trip 40, mounted upon the alarm-post 41 and designed when the alarm of the clock is set off or tripped to engage the adjustable end 35 of the trip-lever 25 and swing it for the purpose of rocking the trippawl 23 and effectingits disengagement from the notched wheel 22 to release or trip the motor at the desired time to cause the match to be lighted and presented to the inflammable material.

It is obvious that where clocks of various sizes are employed the alarm or other arbor will bear different relations to the trip-lever 25, and it is for the purpose of accommodating such varying diameters that I have provided the adjustable end 35, which may be properly deflected in order to bring it into proper operative position with a trip of any character.

In Fig. f the drawings I have illustrated a trip or cam carried by an arbor other than the alarm-arbor and designed for the tripping of the ignition device at any desired time either before orafter the alarm is sprung or during the sounding of the alarm, as desired. Another important feature of the invention is a novel match-holder designed to also provided with a transverse slot 44, into which extends a stop-pin 45 on the arm, and its inner end is counterbored for the reception of a spiral spring 46, having its opposite eeaesa ends connected to the shaft and holder for the purpose of constantly urging the holder axially. 47 indicates a collar retained upon the shaft against the counterbored end of the holder, as by a set-screw 48. At its outer end beyond the extremity of the arm 8 the holder is provided with a diametrical matchreceiving aperture or socket 49, which when the holder is at the limit of its movement under the influence of the spring is disposed substantially perpendicular to the base. The match is retained within this socket 49, as by a match-retaining screw 50 or like device. At the side of the base opposite the stop 19 I provide a gage-plate 51, by means of which the elevation of the match-head from the base to insure its proper presentation to the ignition-snrface may be determined.

The operation of my device is as follows: Supposing the device to be positioned as indicated in full lines in Fig. 2 of the drawings, the presentation of the trip or ofiset to the trip-lever at a predetermined time will oscillate the trip-lever to withdraw the trip-pawl from the controlling-wheel 22. The force of the spring 15 will then be exerted to swing the match-carrying arm in the direction of the stop 19. During the course of the movement of the arm the fulminate head of the match will be presented to the ignition-surface 14, and the spring-urged match-holder will yield sufficiently to prevent the breaking of the match-stem as the match is swept across the ignition-surface into effective proximity to the inflammable material or fuel. The movement of the arm will be such as to create su fficient friction to ignite the head of the match, but will be regulated to prevent undue jarring of the parts by the rotation of the governor or fan 20. As the arm reaches the extreme position (shown in dotted lines in Fig. 2) it will be stopped by the stop 19, and the cam 01' trip 40 having by this time moved out of the path of the trip-lever the latter will resume its normal position and the trip will again engage the pawl 22. The motor is now' set, and in order to reset the entire apparatus it is simply necessary to swing the arm 8 back to its normal position against the resistance of the spring 15 and insert another match in the holder when, as will be apparent, the apparatus is ready for succeeding operations.

From the foregoing it will be observed that I have invented a simple and ingenious apparatus which will efiectuallyaccomplish the several objects stated; but while the present embodiment of my invention is deemed to be preferable at this time, I wish to reserve the right to effect such structural variations as may be comprehended by the protection prayed.
