ALARM ATTACHMENT FOR DRlP-PANS.
SPECIFICATION forming part of Letters Patent N 0. 670,463, dated March 26, 1901.
Application filed January 21, 1901. Serial No. 44,064. (l lo model.)
To aZZ whom it may concern.-
Be it known that we, LOUIS VVAHL and GEORGE KEYES, citizens of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Alarm Attachments for Drip-Pans, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.
This invention relates to signal devices for drip-pans; and the object thereof is to provide a device of this class which is particularly designed for use in connection with the drip-pan of a refrigerator, but which may be used in connection with drip-pans wherever employed.
The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of our improvement are designated by the same reference characters in each of the views, and in which- Figure 1 is a perspective view of a drip-pan provided with our improvement, and Fig. 2 a transverse section of one edge of a drip-pan and showing the method of connecting our signal device therewith.
In the drawings forming part of this specification we have shown at 5 an ordinary pan which may be used as a drip-pan beneath a refrigerator or in any other position, and in the practice of our invention we provide a signal device which is intended to indicate when the pan is suiticiently full to be emptied, and
this device consists of a plate or other support 6, having a spring-clamp 7 connected therewith, which is adapted to be passed down over the top edge of the pan, and connected with the front side of the plate or support 6 are two rods 8 and 9, which extend inwardly over the pan and are curved downwardly into the pan parallel with each other. One of these rods, that designated by the referencenumeral 9, is longer than the other, and mounted thereon is a float 10, having a metal top plate 11, and said float is free to move vertically on the rod 9, and the downward movement thereof maybe limited by a collar 12 or similar device secured to said rod.
At the back of the plate or support 6 are two binding-posts 13 in electrical connection with the rods 8 and 9, respectively, and with each of which is connected a circuit-wire 1a, and these wires are in connection with the batteries 15, and placed in the circuit thus formed is an electrical alarm device 16.
It will be understood that the battery and alarm device may be placed at any desired point, and the circuit in which the alarm device is placed may be formed in any desired manner, and when the water rises in the pan the float 1O rises on the rod 9, and when the plate 11 on the top of the float strikes the rod 8 the circuit is completed through the wires 14c and the signal or alarm device 16 will be operated.
This device is simple in construction and operation and comparatively inexpensive, and it will be apparent that changes in and modifications of the construction described may be made without departing from the spirit of our invention or sacrificing its advantages.
Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. An alarm device for drip-pans consisting of a plate or support and a clamp for connecting it with the pan, two rods connected with the said plate or support and extending forwardly and downwardly and one of which is longer than the other, a float movabiy mounted on the longer rod and provided with a metal top plate, and binding-posts connected with said plate or support and in electrical connection with said rods, substantially as shown and described.
2. The combination with a drip-pan and an alarm device consisting of a plate or support 0 and adapted to be connected with the top edge of the pan, and provided at one side with two rods which extend inwardly over the pan and downwardly thereinto, one of said rods being 2 sweet:
longer than the other and provided with a presence of the subscribing witnesses, this vertically-movable float having a metal top 17th day of January, 1901. plate, said plate or support being; also provided With two binding-posts in electrical connection with said rods, substantially as shown and described. I WVitnesses:
In testimony that We claim the foregoing as BARDEN R. SOHOONOVER,
our invention We have signed our names, in CHARLES K. SCI-IOONOVER.
