` MESSAGE-RECORDING INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 426,554, dated April 29, 1890.

Application iled June 25, 1888- Serial No. 278,170. (No model.)

To all whom, it may concern:

Be it known that I, JOHN C. VILSON, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Message-Recording Instruments, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.-

This invention has for its obj eet to construct a message-recording` instrument especially applicable for police-signaling purposes and adapted to register all signals transmitted from a police-signal box to the central station.

The register isadapted to record all on-dntyor patrol signals silently, and upon the occurrence of a special'signal or one requiring immediate attention to bring into operation an audible alarm or distinguishable signal. The registeris desired to feed a definite length of paper` forward for each signal, and to bring into operation a time-stamp,which operates to stamp the time upon the strip of paper upon which the signal is bein gor has been recorded. The register 'is also designed to effect, through suitable intermediatemeehanism, the answerback transmitter.

The invention consists in details of construction to be hereinafter pointed out.

Figure 1 represents a plan view of a register embodying this invention; Fig. 2, a vertical section of the register shown in Fig. l, taken on the dotted line Fig. 3, a detail of the creeper to be described; Fig. 4, a vertical section of the register shown in Fig. 1,

taken on the dotted' line y fy; Fig. 5, a detail of the inking device to be referred to; Fig. G, a detail of the winding device to be described;

Fig. 7, a detail of the Winder, and Fig. S aY diagram showing the several parts of the register and circuits.

The paper upon which the signals are to be recorded is placed or wound in the form of a coil upon a reel @placed upon a stem or pin a', fixed to the outer' end of an arm a2, fixed to or formed as a part of the box-like frame A, containing all the operating part-s. The reel a is prevented from slipping off the stein by a nut CL3.

The paper is passed through a slot 20X, formed iu one of the side walls of the boxlike frame and beneath a roll 21X, and is presented to the paper-feeding devices now to be described. The paper-feeding devices consist of a wheel 22", having a toothed or serrated edge fixed to a shaft l), having its bearings in the frame-work, and also of a rotating presser-wheel b', loosely mounted on an arm b2, pivoted to the frame-work, the outer end b3 of said arm projecting or extending through an opening in one of the side walls of the main frame. A spiral spring b4 is placed beneath the end b3 of the arm be, the tendency of which is to maintain the rollerpresser b in contact with the toothed wheel 22x or upon the paper which passes over the toothed wheel 22X, thereby pressing the paper in contact with said toothed wheel 22", by which it is fed forward. The paper is fed forward beneath the spring-arms c, attached to the under side of the ink-receiver c', and thence forward beneath the spring-arms c?, thereby holding the paper upon the plate c3.

To mark or print the signal upon the paper, which, it is to be understood, is done by either dots or dashes, one or more marking-surfaces c4 are provided, (herein shown as four in number,) formed as a part of or attached to a roll or sleeve 0'", mounted upon the rod or shaft (l, extending the entire width of the frames. A toothed wheel c"', fixed to the sleeve e", is engaged by a pinion c?, fixed to a shaft 08,10- cated beueath the sleeve, said shaft es having fixed to it a pinion el", which is engaged bya toothed wheel cl2, fixed to the shaft b, above referred to. By the arrangement of gearing the marking-surfaces will be revolved in a direction opposite to the movement of the paper itself.

The marking-surfaces c* are located just above the paper, and the paper is lifted into contact with said surfaces by pens, and as I have herein shown four such surfaces four peus e are also employed, the free or outer ends of which when lifted strike against the under side of the paper and lift it against the marking-surfaces. The pens c are attached to the armature-carrying levers c', pivotcd at- @2 to a suitable frame-work, the said levers c having attached to the under side thereof armatures c ol' the electro-magnets c, four elcotro-magncts being herein shown. The electro- IOO magnets c4.are placed in different circuits, and hence are independently operative.

The marking-surfaces are su pplied with ink by suitable felted rolls f, bearing directly upon them, said rolls f being loosely pivoted to or journaled in the outer ends of arms or framesf, loosely mounted upon a rod f2, held in suitable slots f 3, cut in the side plates f4. The rolls f fall by gravity, as best shown in Fig. 5. A rod f5 is attached vto the rod f2, extending laterally through an opening in the main frame, (see Fig. 1,) which may be grasped by the hand and drawn in the direction of the arrow 2, the rod f2 sliding. in the slots fis until the felted rolls f bear upon an ink-roll g, placed in the ink-reservoir c and fixed to a shaft g. A toothed wheel g2 is fixed to the shaft g', which is engaged by a toothed Wheel g3, fixed t0 the shaft d, upon which latter' shaft the sleeve c5 is mounted. It will'thus be seen that the felted or absorbent rolls f may besupplied with ink Whenever desired, and will continually bear upon the markingsurfaces, as described.

The motor mechanism employed for the register is one that is normally Wound, it comprisingthe drum B, containing the mainsprin g mounted on the winding-shaft B. A ratchet- Wheel c' is fixed on the winding-shaft B and a pawl'i, pivoted at i2, engages the teeth of the ratchet-Wheel, it being normally held in engagement by the spring i3.

The Winder (see Fig. 7) consist-s of a ratchettoothed block 30, held and freely rotatable in a hand-piece 31, said block having a squared hole at the center to receive the squared end of the shaft B. A spring-controlled paWl 32 is also employed for enabling forward rotation of the ratchet 30. As the shaft B extends entirely through .the main frame-Work and has each of its ends squared, as shown, it may be engaged by the Winder at either side of the machine.

A Geneva stop F is used, in connection with the Winding-shaft, in usual manner.

The drum B is provided circumferentially with teethj,`f'orming the main driving-gear, which engages the pinion j', fixed to a shaft j?, said shaft having also fixed to it a toothed wheel j3,\ vhich engages and drives a pinionji, fixed to the shaft d. A toothed wheel j is also fixed to the shaft (l, which engages and drives the toothed Wheel c, fixed to the shaft b. Another toothed Wheel j is also fixed to the shaft d, which engages and drives a pinion f, (see dotted lines, Fig. 2,) fixed to the shaft j.

The escape-Wheelj9 is fixed to the shaftjs, aud the palletj10 is pivoted to the main frame, which co-operates with the escape-Wheel. A detentj1L (see dotted lines, Fig. 2) is fixed to the shaftjs. A releasing lever or bar n, fixed to the rod fn', has at its outer or extreme end a projection which engages and holds the detentjl?. A lug 'n2 is adjustably fixed to the rod n', which is acted upon by a rod ori, ad-

justably attached to the upper end of the .armature-carrying lever n4, fixed to the rod a5, the armature a of said lever being attracted by the starting-magnet M. An arm 917 is also fixed to the rod ni, the upper end of Which co-operates with or vibra-tes between adjustable front and back stops 3 4. It is designed that the shaft ji shall make onethird of a revolution each time the start-ingmagnet M operates, and hence a disk as is fixed to the shaftjz, which has on its periphery three notches, as a, and the releasing-lever 'n has on its under side a lug or projection nm, which enters one or another notch no.

By the motor mechanism herein described the feeding device is adapted to feed a definite length of paper forward each time it operates.

The registeris placed in practice in a local or normally-open circuit, and the Wire 5 from the local battery includes the starting-magnet M, and has, as herein shown, four branches U 7 S 9, which branches include,respectively, the several electro-magnets e4. Each branch 6 7 8 9 is normally open, and is adapted to be closed by the armature of the four relays K, which are included in independent closed circuits, the said wires 6 -7 8 9 leaving the register at R R2 R3 R4, respectively, to include the said relays, and returning to the local battery and entering the register by the Wire 5 at thepost By this arrangement it will be seen that Wheneverany one of the main relays K operates the starting-magnetM operates and one of the electro-magnets c4, and should a second signal arrive on another circuit before the first was completed another electro-magnet e4 operates, and the armature of the starting-magnet remains attracted or is properly responsive. As the electro-magnets e4 operate their armatures cause the pens to lift the paper against the rotating marking-roll. y

The register herein shown is especially adapted for police-signaling purposes to register all calls, and the principle employed IOC- IIC'

is substantially as shown and described in United States Patent No. 359,688, granted to B. J. Noyes, March 22, 1887. In the patent referred to all patrol or on-duty calls were registered silently, and all special calls were registered, and simultaneously a b ell responded to thereby call attention, and the transmitters at the boxes were designed to effect a change in the current for intervals of short duration for all patrol-calls and to effect like changes in addition to a change of long duration for all special calls. In the present invention all impulses of short duration are registered as above described, and on the arrival of an impulse of long duration a creeper,nowto be described, operates. The creeper, as herein shown, (see Fig. 3,) consists of a sector m, havin g a serrated edge, is loosely pivoted to an arm m', fixed to the shaft n', and a toothed or serrated wheel m2 is fixed to the shaftjg, upon the periphery of which the than otherwise.

sector bears. When the parts are at rest, the sector m drops by gravity out of engagement with the wheel m2; but just as soon as the magnet M is energized the said sector is thrown into engagement with the wheel 'm2, and by friction the said sector is raised or turned upward on its pivot. The arm carrying the sector, being fixed to the shaft n', will be vibrated in response to the impulses, and hence will retain the sector in engagement with the wheel m2 much longer on impulses of long duration At the rear side ot the sector a small pin projects, upon which rests the outer or free end of a spring m3, attached to the main frame -beneath the spring m4, but free from it. As the sector is lifted the spring m3 is raised, and upon thel occurrence of an impulse of long duration said spring is raised sufeiently to make contact with the spring m4.

The armature-levers e of the magnets e" each have a back-stop cl2, and wires @12X con- 'nect the back-stop with the binding-posts 13,

' with the exception of the lowest one, are ineluded in said shunts, so that the armaturecarrying levers e of the Vmagnets e", by electrically connecting the wires @12X and 613x, normally short-circuit the said annunciator-magnets. The' lowest annunciator-magnet e16 is included in a shunt-wire e30, leading directly to the battery, but in opera'tion is the same as the other magnets ew, the shunt-wires of which lead indirectly to the battery. lVhen any o'ne of the said levers are attracted, one of the shunts will be broken, thereby including one of the annunciator-magnets, and when contact of the pens m3 m4 is made the local circuit thus formed is closed, passing from the plate 10, pens r11/3071.4, Wire 12, post 13, thence through the armature-carrying levers of all the magnets e4 until it arrives at the one which is attracted, and the current at this point passes through the shunt and its annunciatormagnet' and thence through the remaining armature-levers, returning to plate by wire 20X.

The annunciator-magnets herein shown are adapted to release a drop, which vin falling may, if desired, close a local circuit, (not shown,) including a bell, when t-he current passes through its coils; but said drop forms no part of this invention, and may or may not be employed. If said drop should be omitted, the bell would be included directly in the local circuit of the register.

A disk o is iixed to the shaft g', which has on its periphery two series of contacts, and two pens of o2 lie in the path of movement of the projections of said disk, one for each series'. One of the pens, as o', is adapted to close a local circuit, in which is included an electro-magnet which is adapted to operate a time-stamp,said local circuit passing through plate at 25, disk 0, pen o', wire 26,

post 27, thence including the electro-magnetM 110 of the time-stamp, the battery, and to post to the plate. This local circuit is adapted to be closed after the signal has been received, so as to stamp upon the paper the correct time of the reception of each signal.

In another application, tiled by me January 25, 1887, Serial No. 22d-L34, a circuit-closing disk was shown adapted to close a local circuit to effect the operation of a time-stamp, so that l do not herein lay claim to such as therein shown. rlhe other pen 02 is adapted to cooperate with its series of contacts and close a local circuit, including an electro; magnet which effects the operation of a pole-changing transmitter, by which impulses ot' oppesite polarity are transmitted, which are responsive on a suitable alarm, as a bell, placed in the boxes on the street.

It is designed to transmit one or more impulses at the complet-ion of the reception of each signal, and hence the shaft g,carrying the disk 0, makes one revolution for each complete signal sent in, or while the shaft 3'2 makes one-third of a revolution, and the contacts on the disk o are arranged to engage the pen o2 just as the said disk completes its revolution. This local circuit passes from the Aplate at 25, through the disk 0, pen 02, wire 30 to post 31, thence including the operating magnet 112 ot the pole-chan ger, and the battery-post to plate.

l claim- 1. ln a register, the normally-wound motor, releasing-lever, and starting-magnet, combined with the recording-pen and markingroller, between which the paper is4 fed, the ink-roll and the reservoir in which it revolves, the ink-conveying roller bearing upon the marking-roller and journaled in a frame, and a movable rod supporting said frame, movement of which rod brings the said ink-conveying roller into and out of Contact with the ink-roller, substantial] y as described.
