AUTOMATIC ALARM SIGNAL File g- 1928 2 Sheets-Sheet 2 v A T T Q R N EY Patented eh. 4, 1939 JOHN PELLONI, F ELI-WOOD CITY, PENNSYLVANIA AUTOMATIC ALARM SIGNAL Application filed August 22, 1928. Serial No. 301,366.

This invention relates to alarm signal systems for use within dwellings and the like for, signalling the presence of fire or the attempt at house-breaking.

An object of the invention contemplates.

the provision of annunciators operable by bot-htemperature and contact whereby fires and attempted burglaries may be detected.

Another object of the invention comprehends an operating mechanism whereby the receiver upon a telephone may be lifted, a phonograph started and a bell rung whereby the occupant of the house and the fire chief may be notified of the fire. More specifically stated the operating mechanism is provided with a holding element whereby the device may be supported while being reset.

With the above and other objects in view, the invention further consists in the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a vertical sectional view taken through my invention.

Figure 2 is a top plan. view of the phonograph and telephone.

30 Figure 3 is a detail sectional view taken through the operating mechanism.

Referring to the drawings in detail, wherein like characters of reference denote corresponding parts, the reference character 10 indicates a cabinet within which a phonograph 11 and telephone 12 are supported. The speaker 13 for thephonograph is adapted to face the telephone transmitter 14, the purpose of such arrangement will be presently apparent.

The operating mechanism includes a cylinder 15 having a bottom 16 and within which a plunger or piston 17 is mounted for reciproeating action. The plunger or piston shaft 18, upstanding from the piston, is projected within the core 19 of a solenoid coil 20.

A fusible element 21, preferably stretched across the ceiling or wall of a room or a series of rooms, is passed over a pulley wheel 21' and extended within an opening 22 in the solenoid coil 20 for connection with a ring 23 upon the free end of the plunger shaft 18. Such arrangement normally supports a piston or plunger 17 to occupy the position shown in Figure 1 of the drawing.

A cable 24, having connection with the upper side of the plunger or piston 17, is passed over pulleys 25 and 26 whereby the same may be disposed directly above the telephone receiver 27, whereby the cable when connected to therewith will. effectively lift the receiver when the piston is lowered. By the same token, the cable 28, also having connection with the piston 17 and passed over the pulley wheel 25 and a separate pulley 29, is connected with a switch, arm 30 for the phonograph 11, whereby the telephone receiver 27 and phonograph 11 will be simultaneously set in motion. The record upon the phonograph is adapted to inform the fire and police chiefs of the burning of the fusible element by reason of the fact that the telephone transmitter 14 faces the speaker 13 but it may also be desirous to inform the occupants of the house as well, and in this instance an tor in the nature of a bell 31 is employed.

Said bell is adapted for connection in circuit with a step-down transformer 32 through the instrumentality of a conducting wire 33, whereas its opposite pole is connected with a 8 switch member 34- through a lead 35. The switch 34 is in turn connected with a stationary portion 36 of a knife switch 37 through a conducting wire 38. The knife 37 is adapted for direct connection with the transformer 35 32through a wire 39. Obviously the transformer is energized from the house current and this is accomplished through cables 40 and 41 respectively. The wires 38 and 39 respectively are in turn connected with wires 42 and 43 having connection with contact members upon window frames which when brought into contacting engagement by the raising of a window will ring the bell 31 irrespective of the presence of the knife switch 37.

A spring latch finger 44, operating within a sleeve member 45, is ada ted for connection at its uppermost end with a cable member 46 passed over pulleys 47 and 48 respecber 52.

tively for subsequent connection with the upper side of the piston or plunger 17 in oppositely disposed relation to that of the cables against by a retractile spring 49.

When the occupants of the house leave, for any purpose, the switch 34: may be opened to break the circuit between a stationary portion of the knife switch and the bell, whereby the latter will be rendered inefiective and the burglar will not he scared off.

After the fusible element 21 has been hrokon by the temperature created by a fire, the plunger or piston 17 will drop and actuate the phonograph, phone, and bell.

After the stylus arm for the phonograph has traveled a given distance across the record therefor, a contact member 51 carried thereby is adapted to engage a contact mem- The contact 51, carrying a lead wire 53, is adapted for connection with a contact member 5a located in the path of movement of an osciliating head 55. The other contact 52 carries a lead wire 56 which is connected to one side of the step-down transformer 32 to a lead wire 5'? and the house current. The head is carried shaft 58 able in housing 59 con: the cy nder A lead wire i hetween the head 55 A push button o ected in circuit with the lead l the house current, is adapted to as solenoid cod 6?) whereby the core refer may be actuated simultaneously in conjunction with a shaft member 64: having connection with the shaft member 58 for the head 55 through the instrumentality'ot' an arm 65. The shaft member 64 is in addition adapted for connection at its free end h a knife switch 3?.

illustrated, one iead from the trans .former and house current is adapt-ed for corn nection with the solenoid coil 20.

the element has been replaced the push button is then depressed to shift the shaft member 6 iwherehy the knife switch 3'? may he opened and the shaft member 58 retracted to release the plunger or piston 17.

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention, what is claimed is 1-- An apparatus of the character described comprising a normally inoperative phonograph, a normally inactive telephone arranged to dispose the transmitter therefor in juxtaposition to the speaker of the phonograph, a cylinder, a weight member slidahly mounted within the cylinder having operative connection with a telephone receiver and phonograph brake to efi'ect simultaneous operation thereof, a solenoid disposed adjacent said weight, a plunger shaft for the weight slidably arranged within the core of the solenoid, a local annunciator, a switch member located adjacent and normall held in open circuit with the annunciator y the Weight, a shaft member carried by and extended through the cylinder for frictional engagement with the adjacent surface of the weight member therein, a contact included upon the shaft member in oppositely disposed relation to that of the weight, a stationary contact arranged in the path of movement or and normally frictionally engaging the contact upon the shaft member, and spaced contacts included upon the phonograph and tone arm therefor being designed for ultimate contacting engagement to retract the weight member, brake the phonograph and replace the telephone receiver subsequent to the phonetic and annunciator signals.

in testimony whereof ii afiix my signature.
