PUNCH REGISTER.

Application filed May 19,

This invention relates to punch registers for use in fire or police alarm systems to register and record upon a tape, the impulses transmitted to the headquarters by the intermittent making and breaking of the circuit when an alarm box is operated.4

Devices of this character such as are at present in common use, comprise very com plicated and sensitive mechanism operated by a main spring, which must be kept properly wound in order that the device will function.

Owing to the vast number of small working parts`I punch registers of this type are r very easily thrown out of order, and it is,

of course, essential that an instrument for this purpose must be in perfect working order. l

The objects of the present invention are to provide a simple and efficient punch register provided with an electromagnet connected in the circuit to the alarm boxes, and operated by the making and breaking of the circuit'through any box to feed the tape through the register and punch upon the same the code number transmitted by the impulses from the boxes; and to generally improve and simplify punch registers, obviating the use of a main spring for furnishing power to the register and dispensing with the great number of sensitive and complex parts ordinarily used in devices of this character.

The above and other objects may be attained by constructing the punch register in the manner illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the punch register embodying the invention, parts being broken away for the purpose of illustration;

Fig. 2, a front elevation of the punch register;

Fig. 3, a section on the line 3 3, Fig. 2;

Fig. 4, a section on the line 1 -4, Fig. 2; l

Fig'. 5, a longitudinal section through the clutch; and

Fig. 6, a section on the line 6-6, Fig. 5.

Similar numerals refer to similar parts throughout the drawings.

The punch register is mounted upon a base A preferably of wood, and is enclosed within a housing comprisingr the rounded side plates 1 and 2, the bottom plate 3 which 1923. Serial No. 640,196.

is attached to the base as by the screws Il, and the cylindrical member 5 which is preferably formed of glass, as shown.

The side plates 1 and 2fengage opposite edges of the cylindrical member y5, a. thin strip of felt or the like, as shown at 6 being` preferably provided at each joint. rllhe side plates are fastened together, clamping the cylindrical member between them, by means of the spacing arbors 7 and the connecting screws 8.

An iron bound solenoid 9 is mounted within the housing, being supported upon the side plate 2 and is provided in its lowerv portion with the fixed core 10 having the copper cup 11 in its upper end to separate the same from the movable core 12.

A rocker shaft 13 is journaled at its end portions in the plates 1 and 2 above the solenoid and has pinned thereto a lever 14, one arm of which is pivotally connected as by the link 15 with the movable core 12 of the solenoid.

The other arm of the lever 14 is pivotally connected to theplunger rod 16 slidably mounted in the cylinder 17 which is pivoted at its lower end upon the arm 18 which may be fixed to the under side of the magnet. An adjustable nut 19 is mounted upon the lower threaded end of the plunger rod and a coil spring 2O encircles therod, and is interposed between the nut and the cap 21 of the cylinder.

A gear segment 22 is loosely mounted upon the shaft 13 and provided with the rearwardly disposed tail portion 23 which is pivotally connected to the plunger rod 24 slidably mounted in the cylinder 25 which is pivoted upon a support 26 which may also be mounted upon the under side of the solenoid.

rlhe spring 27 encircles the rod 211 loet-ween the cap 23 of the cylinder and the adjusting nut 29 upon the rod, tending to normally urge the rod and the gear sector into the position shown in Figs. 2 and A rocker arm 30 is fixed upon the shaft 13 and provided with a pin 31 for engagement with the under side of the tail 23.

The `gear segment 22 meshes with the pinion 32 loosely motnted upon the shaft 33 which is journaled in the side plates 1 and 2. The pinion 32 is formed integrally or fixed to the hub portion 34 of the clutch,

Gil

the other member of which comprises a housing 35 fixed upon the shaft 33 as by the set screw 36.

The hub member 34 is provided with a plurality of inclined pockets 37 in each of which is located a ball 38, a spring 39 being located behind each ball and tending to normally urge the same upward in its respective pocket and into engagement with the housing 35.

A gear 40 is fixed upon the shaft 33 and engages the pinion 41 of a governor indicated generally at 42. A worm gear 43 is fixed to the pinion 41 and meshes with the worm 44 fixed upon the shaft 45 upon which is mounted a pair of spring arms 46 arranged to frictionally engage the interior of the cup 47, to check the speed of rotation of the shaft 33.

A toothed feeding wheel 48 is fixed upon the outer end portion of the shaft 33 upon the outside of the side plate 1, and is engaged by the roller 49 mounted upon the pivoted arm 50, which is pivoted to the side f plate 1 as at 51 and normally urged toward the toothed wheel as by the spring 52.

A block 53 is fixed upon the outer face of the side plate 1 and is provided with a horizontal slot 54 to receive the tape 55 as it is unwound from the spool 56 and drawn through said slot by means of the toothed wheel 48.

A vertical bore 56 block punching die to receive the punch 57 which is slidably mounted in a suitable bore in the block 53, and provided with the reduced portion 58 which receives the eccentric pin 59 upon the outer end of the rocker shaft 13.

A cup 60 is supported in a spring bracket 61 beneath the blocks 53 in position to receive the small bits of paper which are punched from the tape by the punch 57, when the punch register is operated.

The solenoid 9 is connected by means of the wires 62, which lead downward through the side plate 2 and through the base A' to the binding posts 63. It will, of course, be understood that these binding posts are connected to the circuit in which the alarm boxes are located.

The circuit is normally closed through all of the alarm boxes and the solenoid in the punch register. When an alarm is turned in, the make and break in the alarm box through which the call is sent, is operated by the signal wheel or other apparatus in the box, intermittently making and breaking the circuit to the solenoid 9 in the punch register.

With each impulse ofV the mechanism breaking the circuit, the movable core 12 of the solenoid is released, the spring plunger 16 rocking the shaft 13 and through the is provided in the beneath the slot 54 and serves as a arm 30 and pin 31 thereon, oscillates the gear segment 22, rotating the pinion 32 loosely mounted upon the shaft 33.

As the circuit is again closed, the solenoid instantly draws the movable core 12 back to the position shown in Fig. 3, releasing the pin 31 upon the rocker arm 30 from engagement with the tail of the gear segment, permitting the spring 27 to pull the gear segment back to the initial position, rotating the pinion 32 and through the clutch rotating the shaft 33 and the toothed wheel 48 thereon, in a direction to unwind the tape 55 from the spool 56.

ln the meantime, the portion of the rocker shaft 13 has caused the eccentric 59 to depress the punch 57, punching a hole in the tape. lt will be seen that as each hole is punched in the tape, the tape isfed forward beneath the punch, so that the next hole is punched at a predetermined distance therefrom, controlled by the timing of the signal apparatus in the alarm box.

The code number of the alarm box operated is thus registered upon the tape and after the last punch has been made in the tape, it will be seen that the gear segment travels back to the initial position, carrying the tape out several inches beyond the punch in order that the box number punched upon the tape may be easily read.

From the above, it will be obvious that the punch register embodying this invention is simple in construction, efficient in operation, and obviates the use of a main spring for furnishing power to the register, as well as dispensing with the great number of sensitive and complex parts ordinarily used in devices of this character.
