FlG. cuit means utilized in connection with the switch means of the invention and showing elements of said switch means relative thereto. 7

As shown in FIG. 1 of the drawings, the switch means "of the invention comprises a cylindrical frame member like while the inner end 14 of the frame lii is disposed 6 is a diagrammatic View of the electrical cir- I to be at the inner side or inner wall surface of a building room or an enclosure.

This frame 18 as shown, for example, is a circular in cross-section tubular member, however, this frame may be of any other cross-sectional structure, as desired, for the purpose of accomplishing the intended uses as will be hereinafter described.

Adjacent the outer end 12 of the frame 18 is a circular flange 16 which is integral with the frame. This flange 16 is disposed to bear upon an outer surface of a building wall or the like as indicated by-a broken line A, in FIG. 1 of the drawings.

Surrounding the inner end 14 of the frame is a flange member 18 which is removably secured to the outer side of the frame 18 by means of a set screw 28. This flange member 18 is disposed to bear against an inner wall surface, as indicated by a broken line B in FIG. 1 of the drawings. This inner wall surface B is intended to be the inner wall surface of a room or enclosure to be protected by the alarm system and switch means of the invention.

It will be seen that the inner end 14 of the frame It is a straight cylindrical portion and that the flange member 18 is provided with a cylindrical extension 22 whereby the flange 18 may be telescopically mounted on the end M of the frame 18 at any location longitudinally thereof, in accordance with the cut off length of the frame 10.

It will be understood that the cut off length of the frame ltl may be arranged in accordance with the thickness of a wall between the broken lines A and B, as shown in FIG. 1 of the drawings. Thus, the frame 10 may be cut off at its end 14 with a hacksaw or the like or may be cut off shorter than its length, as shown in FIG. 1 of the drawings, to accommodate the extension thereof through a wall which is thinner than that indicated between the broken lines A and B.

For purposes of facility, in the cutting of the frame 10 to proper length, the flange 18 is provided with a recess surface 24 which may be used on initial installation for the purpose of establishing a cut off length of the frame 10, for example, the frame 10 may first be inserted through an opening in a wall and the flange 18 may be slidably positioned over the frame whereupon the frame 19 may be scribed at a position coinciding with the recess surface 24. The frame 10 may then be cut off at the scribe mark to establish the disposition of its end 14.

The flange 18 may then be fixed on the frame 10 by tightening the set screw 28.

A tumbler lock 26 is fixed in the outer end 12 of the frame 18 in the conventional manner and a key 28 is removably disposed in the tumbler 26 to cause rotary action of its rotating portion 30 to which a substantially square in cross-section shaft 32 is connected.

Positioned in the end 14 of the frame 10 is a switch mechanism retaining cylinder 34. This cylinder 34 is a hollow tubular member having an enlarged flanged end 36 secured to the flange 18 by means of screws 38. The flange 36 rests adjacent the recess surface 24 and the periphery of the flange 36 is disposed in the recess inwardly of the periphery of the flange 18.

Outwardly of this flange 36 is a dial plate 40 which is secured in a recess 42 in the flange 18 whereby a face portion 44 of the plate 4th is flush with the normally inner surface of the flange 18.

The

flanges

36 and 40 are provided with respective

central openings

46 and 48 through which a stub shaft 58 of a switch bridge member 52 extends.

A dial knob 54 is secured to the stub shaft 58 by means of a set screw 56 and this dial knob operates adjacent to the face 44 of the dial plate 40. e r

The bridge switch member 52 is provided with a pair of

bridge contacts

58 and 60 which are insulated therefrom in a block of electrical insulation 62.

As shown in FIG. 4 of the drawings, these bridge con tacts 58 and 6d are arcuate and extend only a few degrees of an are disposed about the center 64 of the shaft 32 which is centered in a central bore 66 within the bridge contact member 52. This bore 66 inscribes the square in cross-section shaft 32 and permits it freely to rotate therein.

It will be seen that the bridge contact member 52 is freely rotatably mounted in the cylindrical portion 34, as hereinbefore described.

Mounted on the shaft 32 and internally of the cylindrical member 34 is a switch rotor member 70. This switch rotor member 70 is provided with a pair of

contacts

72 and 74, as shown in FIG. 3 of the drawings. Each of these

contacts

72 and 74 is composed of a pair of conductors spring loaded toward opposite ends of the switch rotor 70. These contacts are urged in a direction parallel to the axis of the shaft 32, so that they are maintained firmly in contact with one of the

bridge portions

58 or 60, hereinbefore described, or may be therebetween and in contact with the insulation member 62, depending upon the functional disposition of the switch.

The contact member 72, for example, employs a compression spring 76 between

adjacent contact portions

78 and 88 for urging them in opposite directions. The construction of the switch contact 74 is substantially the same.

A pair of bearing contacts 82 are held in the switch rotor 70 and project axially in parallel relation to the

contacts

72 and 74. These bearing contacts 82 are composed of electrical insulation and project from opposite ends of the switch rotor 70 in order properly to support it relative to the contacts 58 and 6t} and electrical contacts 84 and 8d of a switch stator 88 which is fixed in the tubular member 34.

It will be seen that the switch rotor 70 is composed mainly of electrical insulation and that it is provided with a square in cross-section opening 91 which intimately fits the cross-sectional shape of the shaft 32 so that the switch rotor rotates with the shaft 32. The switch stator 88 being fixed in the tube 34 is provided with

electrical conductors

90, 92, 94, and 96 connected to the contacts 84 and 86, as will be hereinafter described in detail. The contacts 84 and 86 are electrical conductors and project inwardly from a contact face 98 of the switch stator. This stat-or 88 is made of electrical insulation so that when the

contacts

72 and 74 of the switch rotor 70 are rotated out of engagement with the contacts 84 and 86 that said

contacts

72 and 74 engage only electrical insulation in accordance with the showing in FIG. 2 of the drawings. As indicated by broken lines C in FIG. 2 of the drawings, the

contacts

72 and 74 may be rotated in a clockwise direction, as shown in FIG. 2 of the drawings, into the broken line position C.

It will be appreciated that in this position C the

contacts

72 and 74 contact insulation material of the switch stator and that the shaft 32 is freely rotatable in a bore 180 of the stator so that it remains stationary while the switch rotor 70 is freely rotatable.

It will be appreciated that the rotating element 30 of the tumbler lock 26 may be rotated 180 degrees so that the

contacts

72 and 74 may engage either the pair of contacts 84 or the pair of contacts 86 held by the switch stator 88.

The manual control knob 54 is manually rotatable from the inside of an enclosure and is provided with a detent 162 engagable with either of two

recesses

104 or 106 disposed at the on or off positions on the dial face 44. Thus, the switch rotor 70 may be operated from the outer side of an enclosure by the key 28*while the

contacts

58 and 60 may be manually moved from the inner side of a building wall or enclosure relative to the contacts 72 and. 74-, as desired.

As shown in PEG. 6 of the drawings, a conventional 110 volt alternating current power supply is composed of

lines

128 and 112 which are coupled to a primary Winding 112 of a transformer 114 having a secondarywinding 11d. Conductors 118 and 129 are coupled to the

lines

168 and 118 to energize a holding coil 122 which is provided with a spring loaded core 124. This spring loaded core 124 tends to move in the direction of an arrow D when the coil 122 is de-energized due to a failure of the alternating current supply conducted by the conductors 103 and 110. Coupled to the spring loaded core 124 are

movable contacts

126 and 128 disposed to uncouple the lines 108 and 110 when the core 124 is moved in the direction of the arrow D by its spring loaded mechanism. Concurrently, contacts 130 and 132 are actuated by the spring loaded core 124 from an open position to a closed position in order to couple conductors 134 and 136 to

conductors

138 and 140, respectively. A battery 142 is coupled to the conductors 134 and 136 and serves as an alternate to the power supply provided by the alternating current conductor lines 108 and 110.

Coupled to the secondary winding 116 of the transformer 114 are conductors 144 and 146 to which the conductors 138 and 149 respectively, are coupled. Thus, the battery 142 may serve to provide an alternate source of power in the event the secondary winding 116 is deenergized due to a power failure of the alternating current supply.

Coupled to the conductor 146 is the conductor 90, as hereinbefore described, which is connected to one of the contacts 84, hereinbefore described. The conductor 92 is connected to the other of the contacts 84 and coupled to this conductor 92 is a further conductor 148 which is connected to one end ot a solenoid actuator 150 which is disposed to close the contact 152 and energize a light 154 as will be hereinafter described.

Coupled to the opposite end of the coil 150 is a conductor 156 which is connected to the conductor 138 and the conductor 144, hereinbefore described.

The conductor 92 is coupled to one end of a buzzer coil 153 and connected to the opposite end of this buzzer coil 158 is the conductor 96, hereinbefore described. This conductor 96 is coupled to one of the contacts 86 and the conductor 94 is connected to the other one of a pair of contacts 86, hereinbefore described.

The conductor 94 is coupled to a plurality of

switches

159, 16h, 162, 164, 166, 168 and 17%. These switches 159-170, inclusive, may be connected to various windows,

doors and other elements of a building enclosure so that when these switches are open an alarm will be sounded, as will be hereinafter described. Additionally, one of these switches may be a fire responsive switch, another may be responsive to water flow in the plumbing connected with or adjacent to the enclosure protected by the present invention.

Coupled to all of these switches 159-170, inclusive, is a conductor 1'72 which is connected to the conductor 146, hereinbefore described.

An emergency light 174 is provided with a conductor 176 coupled to the conductor 138 and in electrical connection with the conductor 144, as hereinbefore described.

Another conductor 178 of the emergency light 174 is connected to the conductor 94, hereinbefore described, so that when any one of the switches 159-170 is closed the emergency lamp 174 will be energized. A conventional thermally responsive time delay means 171 controls closing of the emergency switch 170, as will be hereinafter set forth in the description of operation.

A conductor 1% is connected to the conductor 94 and to an automatic telephone dialing mechanism 182, which is a conventional device. energized, via the conductor 94 and conductor 180, will I sound an alarm to a police station, fire station or other desired area.

I A conductor 184,'connected to the automatic telephone dialing mechanism 182 is coupled to the conductor 92,

hereinbefore described. i p

Also connected to the conductor 184 is a conductor 186 which is coupled to one end of a solenoid'coil 188 having its opposite end connected to the conductor 94 by means of a conductor portion 190.

This mechanism 182, when i A spring loaded contact arm 192 is responsive to magnetic energy of the solenoid 188 and is disposed to be engaged and held by a spring loaded latching contact 194 when the coil 188 is energized. The arm 192 is coupled to a conductor 196 which is connected to the conductor 94 while the latching contact 194 is coupled to a conductor 198 connected to the hereinbefore described conductor 146.

A reset solenoid 2% is disposed to release the latching contact 194 from the arm 192 permitting it to spring up wardly into the position as shown in FIG. 6 of the drawings, said solenoid 2% when energized thus attracts the latching contact 194 and releases the contact arm 192, as will be hereinafter described.

Coupled to one end of the coil 260 is a conductor 262 connected to a reset control switch 264 with which a conductor 2% is coupled. This conductor 2% is connected to the conductor 144, hereinbefore described.

Coupled to the opposite end of the coil 2% is a conductor 2% which is connected to the conductor 198 and the conductor 146, hereinbefore described.

Operation of the alarm system and switch means of the invention is substantially as follows: I

As shown in FIGS. 1 and 6 of the drawings, the alarm system and'switch means is set so that an alarm will be sounded in case any of the switches 159-1749, inclusive, are operated. For example, the switch means shown in FIG. 1 of the drawings, extending through a wall between the broken lines A and B is disposed to control the circuitry in which the switches 159-176 inclusive, are

coupled and these switches, as hereinbefore described,

may activate the alarm circuit when the enclosure is disturbed by some persons breaking and entering, or when a fire starts therein or in the event of a leak in the water supply system adjacent the enclosure. Additionally, one of these switches may be used by a person as an emergency switch, as will be hereinafter described.

In the position as shown in FTG. l of the drawings, the contacts 56 are coupled by means of the contact 7'0 and the bridging contact 5%.

Under these conditions, the alarm circuit and switch means of the invention is in an on position, as indicated in FIG. 5' of'the drawings, and in this position, the en closure or dwelling may be unoccupied by the proprietor who utilizes the key as he leaves the premises to set the tumbler of the lock 26 and the rotating mechanism 39 thereof, in the position as shown in FIG. 1 of the drawings. Having left the switch mechanism in this position, the operation of any of'the switches 159-179, inclusive, will cause closing of the alarm circuit to energize the automatic dialing telephone 1&2, the buzzer 158 and the solenoid 138 which latches the contacts 192 and 194 together to provide for a continuous operation of the alarm circuit until released by the reset solenoid 209 as energized manually through the switch 294 to pull the contact 194 out of latching position and to thereby release the spring loaded contact 192. p

The switch 179 is provided with a thermal time delay device 171 which prevents energization of the alarm circuit including the buzzer 158 and the automatic dialing telephone 182 for a short period of time so'that any movement made by the proprietor of a store, for exampie, to utilize the emergency switch would not cause immediate operwion of the alarm and might ereby pre vent the proprietor from being shot by a holdup man on suspicion of having sounded the alarm.

it will be understood that when any one of the switches 159-170 is closed that the conductor 1'72is coupled to the'conductor 194 thereby energizing the buzzer 158, the automaticdialing telephone 132 and the emergency light 17 i This emergency light 174 may be placed on the top of the enclosure or in an elevated position thereabove or therearound so that it will be apparent to the surrounding observers that there is an emergency at the location of this emergency light. This light may be arranged with a distinctive luminous sign or other indicator so that it will be recognized as an emergency light.

It will be obvious to those skilled in the art that the present circuit provides for comprehensive alarm protection of an enclosure which the invention is utilized to protect When the proprietor or owner of an enclosure or property returns thereto, he may insert the key 28 in the tumbler of the lock 26 and turn the tumbler and the rotating member 30 substantially 180 degrees in order to retract the key 2% therefrom. This amount of rotation causes the shaft 32 to rotate the switch rotor 76 180 degrees, engaging the contacts '72 and 74;- with the contacts 34 and the bridging contact 6%, hereinbefore described, thereby completing a circuit from the conductor 14-6 through the conductor 148 to one end of the solenoid coil 154) which closes the switch 152 and turns on a light 154 internally of an enclosure. Thus, the proprietor may enter the enclosure with the lights on. After he has entered the enclosure, he may reset the switch mechanism as follows: First of all, he must turn the control handle 54 to the off position as hereinbefore described, before resetting the tumbler and rotating mechanism 3%) in order to dispose the

contacts

72 and 74 of the switch rotor 73* in engagement with the contacts 86 of the stator 88.

When the

contacts

72 and 74 are again rotated into position in engagement with the contacts 85, the key 28 may again be removed whereupon the proprietor may close the entrance door which is protected with one of the switches 159-1623. Thus, the respective switch is again open permitting the proprietor or operator to then return the dial handle 54 to the on position wherein the contacts 72 and '74- are abridged by the bridging contacts 58 to complete a circuit across the contacts 86 of the stator 88 and to thereby connect the conductors 9d and 96 so that closing of any one of the switches 159- 170 will set off the alarm system.

Thus, the proprietor, when within the enclosure, may enjoy the protection of the alarm system by a very simple operation of the switching mechanism shown in FIG. 1 of the drawings, which permits activation and de-activation of the alarm circuit both internally and externally of the enclosure. This is accomplished by the key 28 at the outer side of the enclosure and the control knob 54 at the inner side of the enclosure, all operating on a common switch mechanism.

It will be obvious to those skilled in the art that various modifications of the present invention may be resorted to in a manner limited only by a just interpretation of the following claims.
