2 Claims. (01. 179-5) My invention relates to alarm systems in which a verbal announcement constitutes the alarm.
An object of my invention is to provide a means for setting a device in motion, said device to signal the operator at the telephone exchange and repeatedly transmit a message.
Another object of my invention is to provide a device as described, that is adaptable for use where the dial system is employed at the telephone exchange. 7
Still another object of my invention is to provide a device as described, employing a record for transmitting the message that will automatically adjust and place into position the electromagnetically operated transmitter for repeating the message on the record.
Further objects of my invention will become more apparent as the description proceeds, the invention consisting of the following novel features and details of construction which are more fully described and illustrated in the accompanying drawings and pointed out in the appended claims.
In the accompanying drawings Fig. 1 illustrates a top or plan view of the device.
Fig. 2 illustrates a side view showing the arrangement of parts constituting the assembly of the device, and
Fig. 3 is a diagrammaticallayout of the wiring arrangement showing the electro-magnetic transmitting device contacting the record, the amplifier tube, the rectifier tube, the wires leading from the electric power supply, and the wires leading to the telephone exchange.
Referring now to the drawings in which like characters of reference denote corresponding parts, the character l0 indicates a rectangular plate horizontally disposed and supported by a 4 vertical standard I l, forming an integral part i of a base l2 fastened to the plate H] by a plurality of bolts I 3. A motor [4 actuated by the power unit l5 furnishes the motive power to the entire unit and is set into motion when a con- 45 tact I6 is completed. There is a worm l1 mounted permanently to a motor shaft l8, which shaft is supported by bearings 'l9 and 26, in a housing 2|. The worm l'l engages a worm gear 22 mounted on a shaft 23, which is vertically disposed at 50 right angle to the motor shaft l8 and supported by bearings 24 and 25, in the housing 2|. This shaft 23 acts as a support and driving means for an annular disc 26 horizontally disposed at right angles to the shaft 23 and having an insu- 55 lated plate 21 adjacent thereto. The disc 26 also acts as a support for a sound record 26 fastened to it by a washer 29 clamped down by a nut 30, contacting the threaded portion on the upper end of the shaft 23.
The sound record 28 has a series of recording impressions 3| engraved thereona These impressions are employed to engage the needle 32 forming apart of the electro-magnetic transmitting device 33. This transmitting device 33 is hinged at 34 to a supporting arm 35, which 10 is telescopically encased in a hollow vertical support 36 and acted on by a resilient member 31 inserted into the hollow support 36 and held in position by the threaded screw 38. The arm 35 is guided for vertical motion in slots 39 and 39' 15 vertically aligned in the support 36, and is held ina raised position by a latch 40, which is pivotally mounted'to the support 36 at 4|. There is a plurality of contact points 42, 42' and 42" on the annular disc 26 having wires shown at 20 43, connecting same to the telephone exchange system at 44.
Immediately above, and in radial alignment with, the contact points 42, 42' and 42" there is a contact brush 45 mounted to a horizontally 25 disposed'projecting member 46 and connected by lead wires 41 to the telephone exchange line at '46. The support arm 46 operates in a vertical tubular support 49 and is acted upon by a resilient member 50 encased therein. .It is guided in vertical 30 alignment by a slot 5| and is kept in a downward position by a latch 52 pivotally mounted to the vertical support 49 at 53. A contact member 54, rigidly mounted to the disc 26, is radially positioned to contact the latch 46 and a contact member 55 is radially positioned on the disc 26 to contact the latch 52 when the disc is first revolved in a clockwise direction. Immediately below and parallel to the plate l0 there is a pulley 56 mounted on a vertical shaft 51 fastened to the plate ill at 56. A belt 59 over the pulley 56 engages a pulley 66 permanently mounted to the shaft 23. This pulley 56 has a contact member 6| arranged in radial alignment to contact the member 62 slidably mounted by horizontal arms 63 and 63 forming a part of the support 36, and when the contact member 6| engages the vertical member 62 it will elevate same and thereby cause the arm 35 to rise, lifting the entire assembly including the hinged portion supporting the transmitting unit 33.
There is a series of wires 64 fastened to the transmitting unit 33 and terminating into an amplifying arrangement shown at 65 and diagrammatically illustrated in Figure 3, in which the transmitting device is characterised as 88, an amplifying tube at 00, a rectifier tube as ll, powersupplyleaihareahown ,atllandleadsterminatingatthetslephonecschange system at ll. In operation the arrangement, whether it be a *fusible plug. a push button, a manually operated s'vvitchmrtheiikeshomatllisaetintombtion and actuates the motor II by means of the powerunitu. 'lhewcrml'lonthemotorshaftll turnsa worm gear 22 thereby revolving the a by means of the resilient member II and raising the brush ll away from further contact withthe points It, It and 4!". Accordingly the contact member" iscarrieddirectlyintothepathofthe latch ll releasing the member 8! allowing same to drop, causing engagement of the needle I! on the transmitting device II with the impressions 3| on the recording plate". This will cause a reproduction of. the message in the impressions Ii toberelayed throughthewiresil and the amplifying arrangement I to the telephone circuit ll. 1 I
As the disc it revolves in a clockwise direc- 'tionthepuileyll moimted on the shaft is actuates the larger pulley It by means of the belt 6t,' and as the pulley 00 has a a 24 to 1 ratio with the pulley II. the disc I. will re- .volve for example, 24 times before the contact member" reachesthememberllcausingsameto rise in a vertical alignment lifting therhorizontal member 3! and causing the needle I2 to be raised from the impressions". and the weight of the transmitting unitll, which is pivotally mounted on the angularly disposed hinge 84, will return it to its original position. being guided by the projecting member I. on the arm II. In this manner the message is repeated until the device is made inoperative by manually releasing the contact member I. g
In the chosen embodiments of my invention. exemplified by the drawings, there are present certain novel refinements and improvements not heretofore disclosed in the prior art, and which will be hereinafter more contacts during subsequent revolving fuilyrefen'ed'toand my pcintedoutin theappendedclaims.
