Application filed dune .12,

It is an especial object of my invention to provide a mechanism which is certain in its operation, and is not liable, through any failure of mechanism, to tail to record the precise number transmitted from the particular call box opera-ted. It is an object of my invention to provide in a device of this type, novel cam mechanism for positive operation of a perforator and to eliminate the use of springs for the purpose. It is also an object of my invention to prevent any possibility of the punch sticking in the paper, as it is positively withdrawn after each operation.

It is also an object of my invention to pro vide a positive feed for the strip of paper; to provide novel means for controlling the operation of the punch and to eliminate the necessity for frequent winding of the clock mechanism in the punch.

It is further an object of my invention to provide novel means for actuating, adjusting and controlling the operation of a device of this character, and to provide novel means fol-feeding the paper on which the punch operates to register the calls.

It is also an object of my invention to provide the novel combination and arrangement of parts disclosed in the accompanying drawings, in which,

Like characters of reference designate like parts in each of the several views. Y

Referring to the accompanying drawings, I provide a suitable metal base 1, having a suitable casing 2 mounted on same for carrying a paper reel 3 on which a roll of paper 4 is mounted.

The paper reel comprises the reel sides 30 rigidly aflixed to the reel hubs 3b, the outer surface of which hubs are tapered inwardly in slightly conical shape, as illustrated "in Fig. 12, to cause the woodenringorhub 3a of the roll of paper to keep in a central position while in operation 'betweenthe reel sides 3a. I further provide a suitable'thumb nut 361, as shown in Fig. 1, for fastening the reel sides in their normal spaced relation and also to permit of conveniently removing one side of the reelto place a new roll of paper 4 on the reel whenever required.

I provide a cam casing 5 attached to the main casing and having a slot 6 through which the strip of paper 4 is fed, the paper then passing between the lower or fi'xed roller 7 and the upper or movable paper feed roller 8.

Roller 8 is mounted on a pivoted arm 9. Arm9 is mounted on a shaft 11 and is pressed towards roller 7 by a suitable enclosed (and preferably fiat) spring 10, as shown inFigs.

1 and 2, whereby the rollers 8 and 7 engage the strip of paper 4. It is to be especially noted that the rollers 7 and-8are so positioned relative to the slots 6 in the cam casing 5 through which the'strip of'paper 4.- is fed as to engage the strip of paper in a plane oflset from its center so that the punch portion of the paper will not be engaged by the roller and danger of tearing the strip will thus be avoided.

Mounted in the cam casing is a cam operated device 12, in the bottom of which the punch 13 is mounted. The cam operated element is provided with the two cam slots 14 and 15 in which the outer cam 16 and inner cam 17, respectively, travel. These cams function to positively drive the cam operated device and punch 13 in their respective downthe paper. While the punch illustrated in the drawing is designed for making a circular or disc punching, I may provide a punch member 13 of any desired shape, such as a diamond or a triangular shape if desired. The cam. device 12 is vertically movable in a suitable cam guide 50 to which the cam casing is-detachably fastened, as shown in Fig. 7. I provide a suitable bottom strip 5a having a suitable shaped opening 56 for the punch to travel in when it descends past the slog; 6 through which the strip of paper 4 is fe I provide an elliptical cam 16' traveling in the-cam slot or recess 15 and a similar elliptical cam- 17 disposed in a plane transversely of the cam 16 and traveling in the cam slot or recess 14. The cam 16 functions to positively drive the cam device and punch downwardly while the cam 17 functions to positively drive the punch and cam device upwardly; It will be particularly noted that theprovision of this cam device eliminates any need or dependence on springs which have been found unsuitable and undesirable for operating a punch mechanism of this kind where infallibility of operation is essential. The cams 16' and 17 are both aflixed to the main shaft 18. Shaft 18 carries a gear pinion 19,. as shown in Fig. 7, which pinion meshes with a train of gears 20a driven by a suitable double clock spring mechanism 20, as illustrated in Fig. 2. A conventional train of gears is utilized.

Main shaft 18 also carries a stopping arm 21 which is provided with heavy laterally projecting stops 22' approximately triangular in cross section and each of which have a slightly S-shaped tapered surface, as illustrated in Figs. 5 and 6. The reason for this tapered surface of the projecting stops is to receive the impact of the rotating movement of the arm against the stop pin 23.

I also provide secondary smaller releasing pins spaced from the lateral stops 22 an functioning to take up the impact of the rotary movement of the device to positively stop same at the appropriate time. After striking this stop pin 23 which is provided on the pivoted depending link or arm 24, as shown in Figs.'5 and 6, the tapered surface of the projection stops 22 allow them to slide off from the stop pin 23 and allows the secondary smaller releasing pins 25 to contact with the pin 23 of the pivoted locking and releasing arm or link 24. This obviates danger of breaking off the lighter stop pins 37 and insures the positive operation of the device after eachv half rotation of the stopping arm and shaft 18.

As shown in Fig. 5, I provide a transverse shaft 26 in the upper portion of the casing, having a depending arm 24 which carries a lateral pin 23 which alternately engages with one of the pins 25 and is subsequently disengaged from same with each half rotation of the stopping arm 21. The arm 24 is pivotally connected at 28 with the magnet operated arm 29 which latter arm is mounted on. a transverse shaft 30. This arm '29 carries an armature plate 31 which is positioned to be actuated when current is passed through the electro-magnets 32. I provide an adjustment screw 31a for armature 31'.

As shown in Fig. 3, in connection with the electrical conductors leading to one of these magnets, I may provide the approximately U-shaped cla'sps 33 to releasably receive a removable and'conveniently replaceable fuse 34.

I provide a transverse shaft 35-near the end of the main casing to which the weight rod 36 is aflixed. This weight rod is of sufficient length to extend to a position parallel with the stopping arm 21 and to be slidably en gaged by the lateral pins 37 on that arm, these pins functioning to keep the weight rod continuously raised during the rotation of the stopping arm.

Referring to Figs. 2 and 4 of the drawings, I. provide an arm 38 pivotally mounted on shaft 35 and capable of lateral movement. As shown in Fig. 14 I provide a knife'blade 39 forming an extension of arm 38 and adapted to seat on the threaded shaft 40. I also provide a suitable small spring 41 aflixed to this arm 38 to cause it to swing laterally toward an adjustably mounted fixed stop 42 which stop also is carried by the shaft 35. As shown in Fig. 4, the threaded shaft carries a small gear 43 which in turn is operatively connected with the train of gears 206 which are actuated by the clock spring mechanism 20, as shown in Fig. 2. As shown in Fig. 4, the threaded shaft 40 carries a. pin 44 which functions to stop further movement of the machine when the pin 44is engaged by the L-shaped stop 45 which is in fact an ex tension of arm 38. The L-shaped stop 45 and the knife element 39 are integral.

I may provide an encased (and preferably flat) spring 46 affixed to the outer end of the shaft 30 which carries the armature 31, as shown in Figs. 4 and 5. The encased spring 46 functions to cause a rapid operation of the device. The stop 42, as shown in Fig. 14, is adjustably mounted on shaft 35 by means of a suitable screw adjustment 50 to permit of its being shifted laterally on the shaft to regulate the feed of the paper-that is, the length of the strip of paper that will be fed out after the machine has stopped punching. The knife holding arm 38 is also laterally adjustable by means of a screw adjustment 51 on the shaft 35. The purposeof this adjustment is to cause the L-shaped end 45 to look more or less tightly as desired on the stop 44 project ing from the threaded shaft as shown in Figs. 2 and 4.

As shown in Fig. 6 I provide an escapement wheel keyed on the threaded shaft 40 and operatively engaged by the escapement 52 mounted on a transverse shaft 52a to which the weight arm 53 is adjustably mounted, this weight arm carrying adjustable weight 54.

As shown in Fig. 2 I provide the pivotally mounted pawl 56 notched at its free end and adapted to engage a pin 57 in the main shaft 18 to prevent back lash of that shaft.

As shown in Fig. 1 I provide a suitable cup 48 removably mounted in suitable spring arms 47 and positioned under the cam device casing 5 to receive the punchings from the paper strip 4.

As shown in Figs. land 2 I provide a handle (or other suitable means) 61 for engaging the clock spring shaft to wind the spring of the clock spring mechanism 20 which actuates the two trains of gears 20?) and 20a as indicated in Fig. 2.

The device is operated electrically by im pulses transmitted from various signal apparatus at distant points and which apparatus is electrically connected by suitable electrical conduits with the contact members 59 and 59a, which are shown in Fig. 2, and which in turn are electrically connected with the mag-- nets 32 which when magnetized by a current of electricity actuate the armature 31 and thus cause a pivotal movement of the pivoted arm 24 to disengage the stop pin 23 from the lateral pin 37 of the rotating stop arm 21 carried by the main shaft 18. This main shaft 18 is under constant tension by reason of its operative connection through pinion 19 and the train of gears 20a with the clock spring mechanism 20 which is arranged for movement in the direction indicated by the arrow in Fig. 2. Upon release and rotation of the double stopping arm 21 the cams 16 and 17 carried by main shaft 18 are rotated which in turn causes a positive up and down movementof the cam device 12 and punch 13 car ried by that cam device to punch holes in the strip of paper 4. This strip of paper is fed along by its frictional engagement be-'' tween rollers 7 and 8, the roller 7 being mounted on'a shaft which is driven by the train of gears 205 from the clock spring mechanism 20, thisclock spring mechanism functioning to drive both the main shaft and the feed roller and the stop mechanism con trol simultaneously. s.

In operation an important advantage is attained by providing the double stopping arm 21 in that one punch ismade at each half rotation of theshaft 18 and in turn this has the effect ofmaking it possible to wind the clock mechanism only half as often as would be necessary if a complete rotation ofthe shaft 18 was required for each operation of-the punch mechanism.

It will also be particularly noted that the stopping arm and projections are of relatively large size and of heavy material to permit of the use of a heavy clock spring mecha-, nism 20 for actuating the device and the heavy weight and relatively large size of these parts prevents any danger of breakage with the relatively powerful clock mechanism used in my register. v

In registers heretofore manufactured, arms having a similar function to this device have shape from my device with the result that frequent breakage of these parts occurred,

with consequent extra expense for chang ing and renewing of broken parts.

WVhile the main shaft 18 and double stopping arm 21 are rotating the two lateral pins 37 on double stopping arm 21 function to successively contact with weight rod 36 and elevate it and rotate shaft 35 to which rod 36 is affixed sufficiently to raise arm 38 and thereby disengage knife blade 39 from the screw threaded shaft 40. This operation results in continuous feeding of the paper strip dur ing the transmission of electrical signals.

When the transmission of electrical impulses has been completed'and the signal call thereby transmitted has been registered by a corresponding number of holes punched in the strip of paper 4, the main shaft 18 is stopped by engagement of the double stopping arm 21 with the lateral stop 23 on the arm 24 which arm'is operatively connected with the armature 31. The weight rod 36 thereupon descends to its normal lowered position thus rotating shaft 35 to which it is aflixed to a sufiicient extent'to lower the arm 38 so that its knife blade extension 39 will engage in the threads of the screw threaded shaft 40 which will cause the arm 38 to travel laterally dueto its operative engagement with the screw threaded shaft until the L shaped-end 45 engages with the stop pin 44' carried by screw threaded shaft 40, as shown in Figs. 4 and 2. The effect of this limited travel of the blade 39 and shaft 38 in engagement with the screw threaded shaft 39 is to permit a short strip of three or four inches of the paper strip 4 to be fed out beyond the rollers 7 and 8' so that the paper strip may be readily torn off by the person using it at the fire station, police station or other central ofiice without danger of tearing into the portion of the strip in which the punched holes appear and which punched holes indicate the number of the signal thereby registered by the machine to correspond with the number of the signal box from which the desired signal was transmitted from some distant portion of the city.

The above description describes the operation of the register on a so-called open circuit. On a so-called closed circuit its action is identical so far as the mechanical features are concerned, the difference being only that in open circuit operation the armature of the electro magnet is attracted to the coils when energized, while in closed circuit operation'the armature of the electro magnet is released when the circuit is broken, and attracted and held by the coils when the circuit is again completed.
