AUTOMATIC ALARM AND BURNER CONTROL Filed Feb. 26, 1932 Y 3 Sheets-Sheet 3 7 I Q lnuenior A llome y Patented Nov. 8, 1932v HEN'RY C. VOGT, OF NEW BRUNSWICK, NEW JERSEY AUTOMATIC ALARM AND BURNER CONTROL Application filed February 26, 1932. Serial No. 595,413.
This invention relates to an unusual com;- bination of devices and. means mechanically co-ordinated to provide a unique control appliance or apparatus for boiler, cellar, and furnace room usage.
The invention has to do with an unusual co-relation of mechanical and electrical accessories forming an eflicient and satisfactory electro-mechanical. automatic control and fire extinguisher arrangement for use in conjunction with a boiler.
One purpose of the invention is to provide door actuated mechanical control means for automatically tripping electrical switches, one to operate an audible signalling alarm, and the other to cut-off the electric motor of an oil burner, the arrangement being such that the structure is brought into play in the event that any one of the doors on the boiler or furnace is blown open by gas or combus tion explosion within the firebox of the boiler.
Another feature of the invention is predicated upon a multiple element fire-extinguisher arrangement wherein the extinguisher unit issuspended in position to co-operate with an underlying device constructed to cut off the oil burner motor and sound the danger alarm.
Thepurpose of the invention is to provide a sort of silent watchman andcfireman so to speak which constitutes unique emergency means to out off the oil burner, when a burner is used, and to sound an audible alarm to give signal to the anitor that something is wrong in the basement.
In the drawings Figure 1 is a diagrammatic elevational view disclosing the complete assembly and arrangement constructed in accordance with the present invention.
Figure 2 is a front end elevation showing the door arrangement on the boiler.
Figure 3 is a top plan view of one of the parts of the complete assemblage.
Figure 4 is an exaggerated section on the 45 line 4-4: of Figure 1.
In Figure 1, the numeral 5 designates a conventional boiler, 6 designates a motor driven oil burner, 7 represents an audible alarm (preferably a gong), 8 indicates a to switch for controlling the alarm, and 9 the second switch for controlling the motor of the oil burner 6.
The levers of the respective switches ar distinguished by the numerals 10 and 11 respectively, and are tied together by a link 12 for simultaneous operation. The free end portion of the lever 11 is engaged in a keeper notchor seat of atrip finger 13 pivoted. on the upper end of a standard 14 carried by suitable wall brackets 15. The numeral 16 designates 66 an actuating spring connected torthe intermediate part of thelever 11 and anchored on the bracket so that as soon as the lever 11 is released by the trip 13 both switches will be operated to sound the alarm and cut off the motor to the burner at substantially the same instant.
The trip finger 13 is controlled by a flexible chain 17 whose horizontal portion 18 is V trained over pulleys 19 and 20 hung from ap- To propriate ceiling brackets. The depending left-hand end of the chain 21 is anchored at 22 on a stationary wall bracket 23 located within the vicinity of the stack or pipe 2 1. This chain is actuated by automatically oper- 7.: able means which in turn is actuated by the doors on the boiler.
As seen in Figure 2, the upper doors are distinguishedby the numerals 25 and 26, and the lower door by the numeral 27. Anchored 86 on the front wall of the boiler as at 28 is a spring arm or finger 29 having a ball-like knob or head 30 co-operable with the door 27. The numeral 31 designates a similar spring which is bowed as indicated and rockably mounted between its ends in a bracket 32. This has terminal knobs or heads 33 and .34: in contact with the free swingable ends of the doors 25 and 26. V 7
Connected by short cords 35 and 36 to the m knob end of the actuating members 29 and 31 is a ring 37 which serves as a coupling between these short cords and the mainpull cord 38, and this pull cord 38 extends through a guide 39 upwardly over a pulley Q0 where it is connected with the horizontal part 18 of the switch control chain as seen in Figure 1.
It is evident that the knobs on: the ends of the members 29 and 31' are located inthe 10i path of swinging movement of the doors. Hence if an explosion takes place within the furnace and any one of the doors is blown open, the actuating members 29 and 31 will come into play to exert a pull on the cable or cord 38 which in turn will actuate the chain 17. The chain will lift the latch 13 and release the lever 11 and the spring 16 will operate both switches. Hence the alarm 7 will be sounded and the motor to the burner 6 will be cut off. The alarm will serve as a warning to the fireman or janitor so that he may investigate the trouble and reset the mechanism for further use.
Also suspended from the ceiling is a hanger supply pipe 41 from which a plurality of fire extinguishing devices are suspended. As seen in Figure 4, each extinguisher is denoted by the numeral 42 and comprises a glass bulb or globe-like container for suitable fire extinguishing liquid or chemical. This is so fashioned and shaped as to permit it to be seated in an annulus or ring 43 carried by a segmental fusible band 44 attached to the hanger pipe 41.
I next call attention to a trip device indicated by the numeral 45 and comprising a pair of horizontal spaced parallel rods 46 carrying lonigtudinally spaced impact discs 47. The discs are arranged in longitudinally spaced relation directly beneath the superposed chemical extinguisher. Hence in case of fire in the boiler room the fusible bands 44 are designed to give way, allowing one or more of the extinguishers to drop downwardly.
As each extinguisher is locatedover an underlying disc 47 it will naturally strike against said disc, producing suflicient impact as to exert a pull on the device 45 which will in turn actuate the chains 17 and release the latch 13 to control the alarm and burner in the manner already described. Hence the fire extinguishing means not only aids in extinguishing the blaze but cuts out the burner and gives an audible danger alarm.
It is obvious from the drawings and description that there are two sources of control for the switches 8 and 9. In other invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.
