l G. LANDMAN KETTLE ALARM lune 30, 1931. l
Filed Dec'.
Lan dm an gNVENTOR ATTORNEY Patented June 30, 1931 UNITED STATES mism oFFieE KETTLE ALARM Application led December 29, 1930. Serial No. 505,303.
rlhe main object of this invention is the provision of an alarm for kettles or similar cooking utensils where it is desirable to know when the contents of the utensils are 'U boiling; the alarm being adapted to provide audible means operable by the vapor' resulting from boiling of the liquid.
Another object is the provision of such a device having means for varying the pitch 10 of the audible alarm to a desired distinguishing sound for use in suoli cases where other sounds or noises may interfere with the clear perception of the signal desired.
The above and other objects will becomey 15 apparent in the description below in which characters of reference refer to like-named parts in the drawings.
Referring briefly to the drawings, Figure 1 is a fragmentary elevational view of a ket- 20 tle equipped with the alarm.
Figure 2 is Ia longitudinal, sectional, elevational view of the alarm attached to the tip of the spout, the latter being shown fragmentarily.
Figure 3 is a view similar to Figure 2 illustrating a modified form of the device.
Figure d is a cross-sectional view takenk on the line %4 of Figure 3.
Figure 5 is a perspective view of the block shown in Figure 3.
Referring in detail to the drawings the numeral represents a kettle having the usual spout 11. The alarm comprises an upwardly tapering body 12 having its lower edge rolled for' the sake of reinforcement as shown at 13. The upper end of the body converges to form a dome-like tip 14 having a central opening 15 therein through which the shank of a knob 16 projects, the knob being retained in said opening for the purpose of handling the device. In the upper portion of the body openings or recesses 17 are provided. A flat disk 18 is secured within the body and provided with opposite ly disposed recesses 19 formed turning downward flaps 20 cut from the disk. It is obvious from this disclosure that when steam passes upward through the alarm and out through the openings 17, the flaps 20 as well as the edges of the disk bordering the recesses 19 will be set into vibration and will cause a whistling sound. Because of the fixed relation of the parts described this form of the alarm will be capable of giving off but a single liXed pitch and is therefore suitable for use where no other similar uten- Y sil is being used. In the form shown in Figure 3 the lower portion 12 of the body of the alarm is cylindrical and contained within this portion is a substantially cylindrical block 21 of wood or the like. The upper portionof this block is of narrower diameter than the lower portion and a shoulder 24' parallel with the top and bottom `faces of the block separates the upper from the lower portion. Channels 22 are formed at opposite sides of theupper portion of the block, the bot-toms of these channels being rounded at their upper ends to meet the edge 23 of the upper portion of the block so that these edges may serve the purpose of vibrated tongues adapted to give olf the desired whistling sound. A hole 25 is provided in the axis of the block with its opening on the upper face, this hole being threaded. A knob 26 pr'otrudes from the upper end of the alarm and passes into the device through an opening 28 having a sleeve 27 surrounding the opening and integral with the body of the device. A threaded shank 29 depends from the knob 26 and engages the block 21 in the threaded hole 25. rlhe operation of this form of the device is as follows:
team passing upward through the spout and out through the opening 17 is guided through the channels 22 past the edges 23 thereby setting said edges into vibration. Variation of the pitch of vibration is accomplished by raising or lowering the block 21 and thereby varying the area of the passages through the openings 17 past the vibrating edges 23. This is accomplished by rotating the knob 26, the threaded engagement of the shank 29 with the hole 25 thereby causing the block kto be raised or lowered as desired.
t is to be noted that obvious changes in construction may be made without departing from the spirit and scope of the invention.
Having thus described the invention What is claimed as novel is as follows:
l. A device of the class described comprising a substantially tapering body having openings therein7 a block slidable in said body and having longitudinal channels therein said body having vibrating tongues thereon at the ends of said channels adjacent said openings7 and means for varying the longitudinal position of said block with respect to said openings in order to vary the pitch of vibration of said means upon the passage of steam through said openings.
2. A device of the class described comprising a. substantially tapering body having oppositely disposed openings therein, a block registering in said body and having oppositely disposed channels therein adjacent said openings, the upper ends of said channels being curved to meet the upper pe? riphery of the block tace to provide vibratory tongues at the ends of said channels, means rotatable in the upper end of the body of the device, said means engaging said block and serving to slidably vary the position of said block with respect to said openings in order to varythe pitch ofvibration of said tongues upon the passage of steam through Asaid openings.
In testimony whereof I aiiiX my signature.
GERARD LANDMAN.
