CIBC'UZT CLOSER.

Application filed March 31, 1922.

To (1. 4.0720212 it may concern:

Be it known that we, Jason Sorrow-1n Gaines and Man'rru E. CnnrsrrToN, citizens of the United States, residing at Cairo, in the county of i-llexander and State of Illinois, have invented new and useful Improvements in Circuit Closers, of which the following is a specification.

This invention relates to signals, and coinprehends the provision of a mechanism adapted for use in conjunction with boilers, said mechanism being automatically operated at predetermined intervals to close an electric circuit.

lhe nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a view in elevation of the invention.

lligure is a view taken at right angles to Figure 1.

Figure 3 a vertical sectional View through the device.

fi ure l is a iiliagramma'tie view.

Retierriug to the drawings in detail, 10 indicates a boiler which communicates with the water column 11, the latter being arranged in parallelism with the boiler in the usual well-known manner. This communication is established by the pipes 12 each of which is provujlcd with a valve 14.

.iourualed in suitable bearings 15 supported by the water column 11 are shafts 16 and 1? respectively. These shafts are iuouut l for partial rotation and each supper (tlSlC 13. the latter being preferably in dating material and supporting fixed contacts 18. .rrojecting from each of said shafts adjacent its disk is an arm 19, and slidably mounted upon this arm is a counterltcaring weight ill. The movements of the shaft are alternately controlled by means of. floats arranged within the water column 11 adjacent the opposed ends thereof.

Each float is supported by a rod 22 which is secured to the adjacent shaft. The rise and fall of these tloa-ts independently control the shafts iiith which they are associated,

so as to turn the shaft in either direction to make or break the circuit to operate the signal in a manner to be presently described. Supported by the water column 11 is a shaft 24, which is arranged in parallelism with the rotatable shafts, and supports at its outer end a vertically disposed rod 26 which is arranged at a right angle to the shafts 16 and 17 Both ends of this red terminate to provide bearings 27 which slidably receive stub shafts 28, the latter being held fixed relatively to the red by means of set screws or the like 29. Each stub shaft carries an insulated disk 30, which is arranged in confroi'iting relation to one of the disks above mentioned, and carried by each disk 30 is a fixed contact 31. Also supported by the fixed shaft 24: are conduits 32 through which the conducting Wires are passed, there being one of these wires 33 coupled to each of the fixed and movable contacts above referred to, and also leading to a switch 35 and the signals 36 and 37 respectively. It might be here stated that the signals 36 and 37 may be of any suitable construction and of any type signal, other than an audible signal which is hereinshown as bells.

In practice, when the water is admitted to the water column 11 and reaches its high level within said boiler, the float at the upper end of said boiler is elevated, thereby partially rotating the adjacent shaft 16, with a consequent turning of the disk supported thereby, bringing the movable contact into engagement with the fixed contact and closing the circuit to sound the alarm or hell indicated at 36.

As illustrated in Figure 4, the current flows from the source of supply 38 through the switch 35, to the contacts above mentioned, thence through the alarm 36 and returned by the wire 39 to the batteries or source of current 38. When the water in the column 11 falls to a predetermined level, it operates the float in the lower end of the boiler, turning the adjacent shaft to close the circuit in the manner above described in connection with the bell 36. The bells 36 and 37 are designed to provide diiferent tones or sounds, so that the engineer or attendant will be able to determine at some remote point, conditions as they exist in the boiler room.

While it is believed that from the foregoing description, thenature and advantag s of the invention will be readily apparent, we desire to have it understood that we do not limit ourselves to What is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

WVhat we claim is 1. In combination with a reservoir and a plurality of floats pivotally mounted therein, a rock shaft extending from the float, a disk carried by the end of the rock shaft, contact elements carried by the disk, a vertical bracket member, supported adjacent the reservoir, axially adjustable element carried by the ends of the bracket member, a disk carried by each of the axially adjustable elements, and contact elements extending from the disk and adapted to be engaged by the first mentioned contacts, the contacts in the last mentioned disks being adapted to be connected with the source of electrical energ which in turn is connected with a signa In testimony whereof we afiix our signatures.
