ALARM-BELL.
SPECIFICATION forming part of Letters Patent No. 382,343, dated May 8, 1889- Application filed February 16, 1895. Serial No. 26-i,209. (No model.)
rior mechanism and float or ball and lever in full view attached to a pan, which is shown in sectional elevation, showing the action of my apparatus under a rising substance. Fig. 2 shows the base or under part of' my apparatus lo a modified form from that shown in F g. 1. Fig. 3 is an end view of said apparatus wlth clamp attached; and Fig. 4 shows in plan the bottom plate of the wheel mechanism with the alarm-hammer and slot through which the pin e of the haminerlplays.
Like letters refer to like parts.
[the object of my invention is to produce a simple, cheap, and easily applied and managed alarm-bell applicable to many uses in both the technic and household arts, and to that end I construct my device substantiallv as follows, namely: a
I adopt a mechanism, 0, provided with a bell, b, hammer, d, lugs a and spring-winding mechanism, as already known in the arts, and set it upon a bell or triangular shaped base, a, provided with blocks a, uponwhich fit the inclined lugs a cut and bent down from the base-plate c of the mechanism 0, and secured to said blocks by means of screws or pins. To the edge of the base a, and near where the end of the lever carrying the hammer d is fulerumed, is a bearing, o to which is pivoted a lever, g, on a pin, h, in such a manner as to allow vertical play only to said lever, and said lever extends beyond said point or pin h until it reaches a short but sufficient distance beyond the pin e of the hammer d, so as to form a certain stop to its motion whenever the free end, 9', of said lever rises to obstruct its motion. Said pin e fastens the hammer (Z to its lever, and it also extends below the base-plate c of the mechanism 0 a sufficient distance to reach beyond said arm 9 when it is up near the plate 0, as shown in full lines in Fig. 1', and said pin plays in the segmental slot f cut through the said base-plate c, Ihe construc- .,tion and position of the hammer and the wheel which drives it are clearly shown in Fig. 4.
The bell-shaped base a protects the mechanism above it from accidental or intentional interference; but it may consist of .a three-arm piece provided with the parts caa", as shown in plan view in Fig. 2, when the bell-shaped part is omitted. Under the center of said base a, or in the corresponding place under said three-arm piece, is attached a leg, 2', to which is attached a clamp, j,'providcd with a clamp-screw, h. Said clamp is attached to said lug i by means of a rivet or screw, 2', which presses the contactsurfaces of the clamp and lug together, so asto form a friction-joint, regulated by means of said screw i, whereby said clamp may be set at any angle, so as to place and hold the bell and ball g in the most advantageous position. Said ball g is either made of wood or metal, so as to float upon liquids. In the drawings my alarmbell is shown attached by means of its clamp to a pan, Z, and the ball g is shown upon a mass of dough, m, in said pan, which is set for rising up to the dotted line, and
when that has happened the ball and itslever and arm will be in the position shown in dotted outlines, whereby the pin 6 will be released, which was until then held by the arm 9, and the hammer d allowed to sound the bell.
My alarm-bell is designed to be attached to any apparatus in which liquids are liable to overflow accidentally, or in which they are not to rise beyond a certain point without giving an alarm, to water-tanks, bath-tubs, water closets, locomotive-tenders, bread-trays, firealarms, and all similar uses.
What I claim is* 1. An alarnnbell consisting of a bellshaped base having an exterior supporting-lug, i, and marginal fulcrum h, provided with a lever, 0, having arm 9 at one end and float g at other end of said lever, and internal bearings, a, on said base, in combination with an alarm-bell mechanism mounted on said internal bearings, a, actuating a hammer provided with a pin extending below its base-plate c and engaging with the arm 9, said base-plate having lugs a hammer provided with a pin extending below secured to said bearing a, substantially as the base-plate of the alarm mechanism and specified. engaging with the arm 9, said base-plate hav- 2. An alarmbell consisting of a bell-shaped ing lugs a secured to said internal bearings, 5 base having an exteriorlug, t, holding a clamp, a, substantially as specified.
j, and a marginal fulcrum, h, carrying alever,
T T 9, having at one end an arm, 9, and at the ROBERT HITSOL' other end a float, g and internal bearings, a, Witnesses: g in combination with an alarm-bell mechanism WM. ZIMMERMAN,
IO mounted on said internal lugs, actuating a J. L. ABELL.
