AUTOMATIC THERMOREGULATOR lFOR BOILEB AND OTHER FURNACES.
Application filed July 11, 1922. Serial No 574,314. l
Tof/7l Hmm '1 muy con/'ern j Be 1t known that I, Tiroaras L. Baluma, a citizen of the United States. residing 1n the city and county of Philadelphia, State oit' Pennsylvania, have invented a new and useful Automatic Thermoregulator for loiler and Other Furnaces, of which the following is a specification.
My invention consists of a novel construction of a casing for a magnetic switch, said casing having upright end members in which .the ends of the core of the solenoid magnets is supported, said upright ends also supporting parallel rods upon which are mounted suitable insulated stationary contacts and a movable Contact also insulated from but slidable upon said rods, said movable contact being actuated in either direction according to requirements simultaneously with the oscillation of a switch lever of novel construction, which is actuated b v the movement of the armature of said magnets, when the latter are energized.
lt further consists of a novel construction of a magnetic switch having a. hollow tube upon which the lsolenoid magnets are wound. said tube being slotted at points intermediate the inner juxtaposed ends of said magnets and the armature of said tube having a pin passing transversely therethrough and through said slots and being in engagement with the lupper end of an oscillatory switch lever, whereby the ends of said transverse pin are adapted to actuate in the desired direction a movable contact mounted on guide rods carried -byl the ends of the switch casing.
It further consists in the novel manner of mounting and assembling the solenoid magnets, the rigid or stationary contacts and the movable contact coacting therewith.
It further consists of other novel features of construction, as will be hereinafter fully set forth.
For the purpose of illustrating my invention, I have shown in the accompanying drawings certain forms thereof which are at present preferred by me, since the same will give in practice satisfactory and reliable results. It is to be understood, however. that the various instrumentalities of which my invention consists can be'variously arranged and organized, and that my inventherethrough,
tion is not limited to the precise arrangement and organization of, these instrumentalities as herein shown and described.
Figure 1 represents a plan view of the magnetic switch member of an automatic thcrmoregulator for a boiler-or other furnace, embodying my invention.
Figure 2 represents a section on line 2--2 of Figure 1.
Figure 8 represents a section on line 3-8 of Figure 2.
Figure et represents a perspective view of the guide rods, the insulating blocks movable thereon, the movable contact carried by said blocks, and the pendant arms depending from opposite ends of said blocks.
Similar numerals of reference indicate corresponding parts. I
Referring to the draav'ingsz- In carrying out my invent-ion, l. employ a novel construction of magnetic switch 1, the detailed constrluftion of said switch being as follows:
',lhe solenoid magnets 7 and S are wound ou a brass tube or core t), whose ends are secured in the ulu'ight ends 1t) of the base i tionary or rigid contact 15 secured thereto by the screws 1G and 17. A similar insulating block 18 is secured to the rods l2, at
`the 'right of the apparatus by the screw block is secured the righthand stationary or rigid contact 2t), by means of the screws 21 and 22. It will be apparent that the rods 12' serve both as supports for the pair of stationary contacts and the movable contact and also to brace 19,` and upon said ,and tie together the upright ends 10, so
that a rigid and durable structure is produced. The core 9 also assists to tie the upright ends 10 together, as is evident.
23 designates a steel plunger or armature, which has a pin 24 passing transverselyV said pin being guided in the oppositely located slots 25 in the tube orcore 9. The ends of the pin 24 are engaged by the hooks 26 located on each side of the tube 9, said hooks being carried by the lever 2T, which is an element of the standard toggle switch 28,.wl1ieh need not be described in detail, as it forms per se no part of my invention, said switch being preferably a Hart and Hageman switch, No.3721, as used in buildings to control lighting circuits, motors and the like, and being rated at 5 amperes, 250 volts, l() amperes, 125 volts.
rlhe transverse pin 24 at one of its extreme positions engages and aetuates the pendant arm 29, which is secured to insulating block 30, which is freely movable on the rods l2 and has secured to its top, one end of the movable contact 31, the other end of said contact being secured to the right,
It will ber seen particularly in Figure 4, that the blocks 30 and 32, the contact 3l and the ` pendant arms 29 and 33 move as a unit, whenever one of said arms is hit by the pin 24, when the latter and the armature move towards or assume either of their extreme positions, which is effected bythe energization of either of the magnets 7 or S.
I preferably locate the 'pendant arms on opposite sides of the insulatingr blocks 30 and 32, as seen in Figure 4, but this arrangement may of course be varied, if desired.
It will now be apparent that I have devised a novel and useful automatic thermo regulator for boiler and other furnaces, which embodies the features of ad vvantage enumerated as desirable in the statement of the invention and the above description, and while I have in the present instance shown and described preferred embodiments thereof which will give in practice satisfactory and reliable results it is to be understood that the same is susceptible of modification in various particulars without departing Afrom the spirit or scope of the invention or sacrificing anyv of its advantages.
Having thus described my invention, what `contact carried by said blocks, arms depending from said blocks, said blocks, contact and pendant arms moving as a unit, an armature in said tube, a transverse pin in said armature projecting through slots in said tube, and a switch lever engaging said pin, the latter being adapted to contact with and actuate said pendant arms and moving Contact when said armature is'. attracted to either of its extreme positions by the energizing of either of said magnets.
2. In a device of the character stated, a magnetic switch comprising a base and upright ends, an elongated hollow tube having its terminals seated in said upright ends, solenoid magnets wound on the outer ends of said tube, a pair of spaced rods above'said magnets having their" outer terminals secured in said upright ends, a stationary Contact mounted on and insulated from said rods and arranged above each magnet, insu- -lated, spaced, blocks slidable on said rods intermediate said magnets, a contact plate fixed upon said blocks, oppositely disposed' arms depending from said blocks, said blocks, contact and4 pendant arms moving as a unit, a slotted armature in said tube, a transverse pin in said armature projecting through said slotted'part, and a pivotal switch lever engaging said pin, the latter being adapted to contact with and actuate said pendant arms and moving contact when said armature is attracted to either of its eXtreme positions by the energizing of either of said magnets.
