I ALARM Filed Dec. 10. 1963 2 Shets-Sheec 1 INVENTORS JZROM! 6. TRUP/A/VO ROSARIO TRUP/A/VO BY United States Patent 3,253,271 ALARM Jerome G. Trupiano, 22105 Violet, St. Clair Shores, Mich., and Rosario Trupiano, 32343 Beacon, Frazer, Mich. Filed Dec. 10, 1963, Ser. No. 329,514 12 Claims. (Cl. 340280) This invention relates to an electrical alarm and in particular to an alarm mechanism for detecting intentional appropriation of a bundle of paper currency.

The objects of this invention are to provide an alarm device that is constructed simply and economically; that is easily installed in existing money tills of banks and other places where paper currency is kept without expensive modification of existing facilities; that is not easily detected by a prospective thief; that is actuated inconspicuously; and that operates simply, quietly, and effectively.

In the drawings:

FIG. 1 is a schematic diagram illustrating an electrical circuit for the alarm when used with one denomination of currency.

FIG. 2 is a perspective view of one embodiment of the alarm device where the alarm is actuated by vertical movement'of the trigger pin of a micro-switch.

FIG. 3 is a bottom view of the device illustrated in FIG. 2.

FIG. 4 is a perspective view illustrating several alarm devices of the type shown in FIG. 1 incorporated in a conventional banking till for several bundles of different denomination currency.

FIG. 5 is a vertical cross section of the device shown in FIG. 2 illustrating how the device is set or armed by a bundle of paper currency.

FIG. 6 is a vertical cross section of the device in its set position.

FIG. 7 is a vertical cross section illustrating an intentional removal of the paper currency which actuates the alarm.

FIG. 8 is a cross section view illustrating an alternative embodiment where the micro-switch having a vertically moving trigger pin shown in FIG. 1 is replaced by a micro-switch having a pivoted trigger arm.

As illustrated in FIG. 1, an alarm indicator 18, such as a bell, buzzer or light, is adapted to be energized by a source of electrical energy '12 through a series circuit including van on-oif switch 14 and a micro-switch 16 of analarm actuating device 18. Switch 16 is maintained open by, a bundle 20 of paper currency. When switch 14 is closed, withdrawal of bundle 20 from device 18 closes switch 16 to energize indicator 10. When protecting bundles of two or more denominations, as with the till illustrated in FIG. 4, a plurality of switches corresponding to switch 16 will be connected in series with source 12 and indicator 10.

Each alarm device 18 comprises a channel-shaped base plate 24 having a flat surface 26 for carrying bundle 20 and a pair of upstanding legs 28 which facilitate installation in existing money tills as, for example, by a single screw 30 secured in till 32 (FIGS. 6 and 7). Switch 14 is mounted directly on plate 24 at the forward end of the channel thereof, although switch 14 may be located ,at a point remote from the device 18 particularly if a single on-off switch is used 'for a plurality of alarm devices. A retaining plate 34 is hinged at the rearward end of plate 24 by a pair of pins 36 which are slidable in apertures 38 and 40 in plates 34 and 24, respectively. Plate 34 is resiliently urged against surface 26 by a pair of compression springs 42, each of which encircles a respective pin 36 and bears against plate 24 and a nut 44 which is threaded or swaged on the end of each pin 36. Plates 24 and 34 have vertically registering aper- "ice tures 46 and 48, respectively. Switch 16 is mounted within the channel of plate 24 on one leg 28 thereof and has a vertically movable trigger pin 50 aligned with apertures 46, 48 for vertical movement therethrough. Apertures 46, 48 are off center, if need be, to facilitate mounting switch 16 directly on one of the legs 28. Switch 16 is a commercially available device where pin 50 is spring biased to a normally extended position which corresponds to a closed switch condition. Switch 16 is mounted so that the upper tip of pin '50 extends above plates 24, 34 when switch 16 is closed, the switch being open when the upper tip of pin 50 is depressed or retracted to a position substantially in the plane of surface 26. A plurality of alarm actuating devices 18 may be used in a conventional money till 32 (FIG. 4) suitably partitioned to accommodate various bundles 20 ofcurrency.

The operation of the alarm device 18 is best understood in conjunction with FIGS. 1 and 57. Initially, switch 14 is open and switch 16 is close-d. To set the alarm, the forward end, the. end to the right as viewed in FIGS. S7, of plate 34 is raised slightly so that one or more bills 52 at the bottom of bundle 20 can be moved freely between pin 50 and the underside of plate 34. Preferably plate 34 is raised above pin 50, so that bill 52 clears pin 50, although it is to be understood that by properly contouring the upper end of pin 50, insertion of bill 52 will cam pin 50 downward. After bill 52 is moved to its extreme left position as viewed in FIG. '6, plate 34 is released and it is pivoted downward by springs 42 toward surface'26. Downward movement of plate 34 carries bill 52 downward, sandwiching it between plates 24, 34. Movement of bill 52 against surface 26 depresses trigger pin 50 to open switch 16. Switch 14 is then closed to set the alarm device 1-8. FIG. 6 shows the alarm device 18 in its set position, pin 50 being held in its depressed or retratced position solely by the shear strength of bill 52. Bill 52 is snugly retained by plate 34 to assure depression of pin 50. With commercially available microswitches having relatively weak springs biasing the trigger pin to its extended position, a single bill 52 has sufiicient shear strength to maintain pin 50 in its depressed position. With pin 56 depressed, switch 16 is open so that when switch 14 is closed, indicator 10 is not energized. In event of an unauthorized demand for paper currency, for example, a bank holdup, the bank teller merely grasps the entire bundle 20, intentionally including the lower bill or bills 52, and withdraws the entire bundle from the forward end of device .18, to the right as viewed in FIG. 7. As soon as bill 52 is drawn to the right past apertures 46 and 48, trigger pin 50 is moved through apertures 46, 48 to its extended position by a spring in switch 16, closing the contacts in switch 16 and actuating the alarm indicator 10.

As best illustrated in FIG. 4, with the bundles 20 positioned on alarm devices 18, the alarm actuating mechanism is Well concealed by the bundle itself, the side partitions, and rearward wall of till 32. The alarm is useful for both loose bundles and bundles bound by a band 58 (FIG. 4). The alarm actuating device is extremely quiet in operation, the only sound beingan inherent click in switch 16 which is barely audible under normal conditions. The undersurface of plate 34 and also that portion of surface 26 abutting plate 34 may be coated or plated .with a suitable material to reduce noise and friction when bill 52 is withdrawn.

In the embodiment illustrated in FIG. 8, switch 16 (FIGS. 1-7) of the type having a trigger pin movable between an extended and a depressed position is replaced by a commercially available micro-switch 60 which is tripped by rotation of a shaft 62. A trigger arm 64 made from small diameter wire is secured to shaft 62 for rotation therewith. Arm 64 has an elbow 65 vertically aligned with registering elongated apertures '66, 68 in plates 34, 34, respectively. Upward travel of arm 64 is limited when an end portion 70 of arm 64 abuts plate 24. Alternatively, suitable stops provided for shaft 62 on commercially available micro-switches may be used to limit the travel of arm 64. A portion 72 of arm 64 forward of elbow 65 is preferably inclined so that when a bill is inserted between plates 24 and 34 and moved to the right as viewed in FIG. 8, the bill will cam arm '64 downward, counterclockwise as viewed in FIG, 8, from an extended position illustrated in full lines to a depressed position illustrated in broken lines. With arm 64 in its extended position, elbow 65 being above plates 24, 34, switch 60 is closed. With arm 64 in its depressed position, elbow 65 lying substantially in the plane of surface 26, switch 60 is open. The undersurface of plate 24 abutting portion 70 may be coated with a suitable noise-reducing material.

An alarm device having the actuating mechanism shown in FIG. 8 operates in substantially the same manner as a device having a micro-switch 16 of the type shown in FIGS. 1-7. However, with arm 64 it is not necessary that plate 34 be raised to clear elbow 65 since arm 64 will be cammed counterclockwise as viewed in FIG. 8 when one or more bills 52 are moved from left to right as viewed in FIG. 8. In a manner similar to that described in conjunction with FIGS. 5-7, when the device is set, trigger arm 64 is held in its depressed position by the shear strength of one or more bills 52 to maintain switch 60 open. When bundle 20, including bottom bill 52, is withdrawn from device 18, trigger arm 64 pivots clockwise to its extended position, closing switch 60 and energizing indicator 10.

As hereinabove described, in the preferred embodiment the micro-switch is positioned so that the actuating arm or pin moves upward when the bill is removed. When the bill is positioned between plates 24, 34, the upper tip of pin 50 (FIGS. 2-7) or elbow 65 (FIG. 8) lies substantially in the plane of surface 26 below plate 34. With the actuating means in this position, switches 16 (FIGS. 2-7), 60 (FIG. 8) are off. When the bill is removed, pin 50 and arm 64 are free to move upward to close the respective switches 16, 60. One aspect of this invention is the simplicity of the alarm device which'is in part achieved by maintaining the switch in its off condition by the shear strength of one or more bills, preferably a single bill, properly positioned in the device. When the bill is removed, movement of pin 50 or arm 64, previously restrained solely by the bill, closes switches v16, 60. The travel of pin 50 or arm 64 necessary to actuate the alarm can therefore be relatively short.
