1 a whom it may concern:

do it known that I, ALEXANDER .J. FIALA,

a citizen of the UnitedfStates,residing at Omaha, in the county of Douglas and State of Nebraska, have invented ainew and useful Alarm Attachment vfor Refrigerator Drip-= Pans; and I do hereby declare the following to be a full ,-clear, and exact description of skilled in the art to which it appertains to make and use the same.

This invention relates to a new and useful ala-rm or signal device for refrigerator drip pans.

' One of the objects of the invention is the provision of an adjustable float, whereby the alarm may be sounded at various heights of the water in the pan. The float proper may be'adjusted to accomplish this purpose, or

'the sectional swinging arm may be adjusted.

to increase or decrease the swing of the arm to accomplish said purpose. In addition a contact screw may be adjusted, in order to allow the alarm to be soundediat various heights of the water.

In the drawings there is disclosed certainfeatures-of construction, but in practical fields these features may necessitate alter 'a.tions,to which the patentee is entitled, providedv the alterations are comprehended withinthc scope of what is claimed. J

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

35 showing the application of the improved alarm attachment.

.Referring to'the drawings more particularly-1 designates a portion of a refrigerator, .while 2 denotes the drip pan, whereas 3 marks the alarm attachment. The alarm at- 5 tachment may be applied to either a round or square pan, and may be provided with either a two or three'cell battery, and a buzzer or hell. 7 v

The alarm attachment 3 comprises a base 4, to which a dry battery 5 is secured, by

\means of the clamp dry ibattery is provided with .a term-inal'Z, which is secured to thebinding screw 8,-there being a wire 9 connecting bet-weeii' said binding screw and the binding post 10 of*the bellor buzzer 11. Anothenterniinal 13 projects from the battery, through which terminal a contact screw '14: is threaded- The-bellfor buzzer is secured to the base 4 as at 15. Also secured to the base as at 16 is a plate 17, by

means of the screws 18. This plate 17 is provided with a pair of laterally-extending parallel arms 19, in apertures 20 of which an angular arm 21 is mounted, the extension 22 of which arm cooperateswith the contact screw 14, so as to opener close the circuit betweenthe bell or buzzer and the bat. tery. By adjustingthe'contact screw 14, the closing of the circuit may be varied. A wire 24 connects between the binding screw 25 of the plate 17 and the binding screw 26 of the" buzzer or belL- A sp=ingE-bracket 27 having an elongated spring portion 28 (whichlies against and parallel with the angular arm 21) and provided with angled ends 29 is'car ried upon the -a-iigularjal'm 21, said arm 21 extending through the angledends', with' it's ends bent slightly in alat'eral direction, to hold the spring bracket-in place. A-second arm 30 terminatingat one .end in'acircular clamp 3.1 for the reception ot-the float-'32 is provided, This float may 'bei 'adjusted .vertically, so that the circuit between the bat tery and the buzzer may be closed at various.

heights of the water. The elongated'portion 33 of the'arin 3O passesthrough the openings 34of' the angled ends 29, and is arranged parallel with the portion 28 of the bracket 27 and the arm 21.: The end 35 of the portion 33 is bentat an angle to hold the arm 30'against movement in one direction or the other, thereby increasing .or'decreasing the arc on-which thefloat moves,

When the water in the panreachv the; float thereby raisingthe float,.t-he' arin' 21..

and the arm 30 are tilted, sothat the exten-" sion 22 of the arm 21 will contact with the screw 14, thereby closing the circuit between the buzzer and the battery, thereby giving The invention having been set forth, what' is claimed as new and useful is In combination with a battery having an alarmsouudirm 'devlce in circuit therewith a circuit closer con' rprising a stationary co1-1- tzu'imember, a bracket plate having parallel arms, a pair of arms adjustable longitudinally with relation to one another, one of which is pivotally mounted in the arms of the bracket plate and provided with an extension to cooperate with said contact memher, while the other arm of said pair of adjustable arms is provided with a circular elainpat one of its ends, and a spring clamp having laterally extending apertured lugs through which said pair. 0t adJuStable arms extends, one end of each of said'pair of adjustable arms having an offset lug to conname to this specification in the presence of two subscribing witnesses.
