VARIABLE-SIGNAL TRANSMITTER.

Specification of Letters Patent. Patented Aug, 14,1917.

Application filed August 7, 1914. Serial No. 855,632.

To all whom it may concern:

Be it known that we, Gina-anon E. Beam-r and I'IERMAN WV. Dori oi-rrr, citizens of the United States, residing at Binghamton, in

the county of Broome and State of New;

York, have inventedcertain new and useful linprovei'l'ients in Variable-Signal Transmitters, of which the following is a specification. This invention relates to tral'lsmitters such as are suitable for control station fire alarm telegraph systems or other service where it is desirable to provide facilities for the rapid manual formulation of various signals.

This invention is particularly adapted to .the type of such transmitters which is pro vided with operating handles or knobs for use'.' initheformulation'of different signals, by adjusting the various handles to the particular digit desired and then initiating the operation of the transmitter by any suitable mechanism.

When such a transmitter acts to formulate a signal comprising two or more digits, it

is customary to have the pause or interval. between the last stroke of one digit and the first stroke of the following digit substan tiallygreater than the interval. between the stroke. within any digit, and it is also customary to arrange such transmitters so that if caused to repeat the digits, the pause from the last stroke of the last digit to the first stroke of the first digit in the next succeed ing repetition of such digits will be substanti ally greater than the pause liietween the last stroke of any other than the last digit and the first stroke of the digit transmitted next thereafter.

One type of such trai'ismitters is ordinarily provided with sectors and their associated parts mounted in suitable relation with a front plate having slots of such length that any one sector may be so adjusted as to permit the transmission of from one to ten con transmitters hert be evenly spaced at comparatively widely separated points in a straight line within an area conveniently reached by the opehator, thus increasing the acclilracy and rapidity of the formulation of a signal. by rendering it unnecessary to slowly and deliberately adj ust the setting handles in order to stop them within extremely narrow limits.

hen the indicating marks are comparatively widely separated an experienced operator is greatly assisted by his sense of position, which enables him to adjust the setting handles for the desired number of strokes without careful visual observation, as he unconsciously associates a certain digit with a certain position of the handles.

The indicating marks for as many as ten strokes may be thus widely separated and the variation in the unit of angular motion of the sectors may readily be compensated for in the design of the apparatus, since this variation for ten divisions would not be as great as the minimum unit of angular is greatly increased, the variation in the units of angular motion would become so great that the lndicating marks could no longer readily be evenly spaced, thus con-- fusing the of position of the operator and delaying his work in formulating a signal and increasing the chance of error.

The area necessarily occupied by these marks would further be more than pmportionately increased, thus' not only covering an excessive area but greatly detracting from ratus.

The starting niecl'ianlsm provided upon fore used, whether of the type to which other features of this invention particu rly apply, or of other types, has been so con .ted that although a cer tain movement of such starting mechanism would set the transmitter in motion, a. further movement of such mechanism was required to amure the complete transmission of the digits to which the transmitter was set, and the movement of said starting'mechanismfar enough to secure the transmission of the digits the desired number of times or that he would move 'such mechanism so far as to cause such digitsto be repeated a larger number of times than intended.

In the use of variable signal transmitters, occasions arise that after the transmitter has been set for certain di its and has been started to transmit said digits for a plurality of repetitions, said transmitter is urgently needed for the transmission of a more important signal, especially when such 'a transmitter has been set in motion for purposes of test or demonstration, but transmitters heretofore provided haveembodied no means for abruptly clearing them of the signal to which they are set, and restoring the parts to normal condition, so that they may be set for the more urgent signalwithout awaiting the completion of the number of. cycles of the operation of the transmitter to which it was set. w.

One of the objects of this invention is to provide means for formulating a signal having more than ten consecutivestrokes without changing the construction of the sectors and Without injuriously aflecting the accu racy and rapidity of the work of an opera tor by varying the location of the indicating marks and also without destroying the symmetrical appearance of the transmitter.

Another object of this invention is to provide a transmitter of the character described having starting mechanism consisting of separately operable members so connected with the transmitting mechanism that when one of these members is operated, such transmitter will consecutively transmit the reective digits to which the setting handles Zr the sectors have been set, while if other of said members are operated it will set the transmitter inmotion to repeat said series, so that, for instance, when released by the use of one of said membersthe series of digits will be transmitted once; when released by another member, twice; when released by another member, three times, etc, these members being so constructed and arranged that any movement of said members which is suflicient to set the transmitter in motion will assuredly set it in motion for the number of repetitions represented by said member.

A further object of this invention is to provide means which may be applied to any form of variable signal transmitter whereby when said transmitter has been set in motion for the repetition of certain digits a given number of times, such setting can be quickly cleared and the transmitter 'promptly brought torest in condition to be set for and started to' transmit a difierent signal by a simple movement of a single part.

Other objects of this invention are to provide a form of variable signal transmitter which will be positive and effective in action and which is adapted to be more 'economi-s, cally manufactured. and will require legs skilled supervision than other like transmitters heretofore devised, and other objects are described in the 'following specification and more claims.

In constructing this invention, a coupling particularly pointed out in the means is provided, which, when manually set in one position, relatively so adjusts two of the sectors associated with the setting handles that when the transmitter is set in motion, the mechanism cooperating with such sectors will cause the pauses between all of the strokes transmitted thereby to be of the duration which the transmitter is intended to provide between the consecutive strokes of an digit to which it may be set, and the number of consecutive strokes transmitted will be represented by the sum of the'digits to which said handles are set.

Starting mechanism is provided, consisting of a plurality of manually operable members so connected to the transmitter structure that the manual movement of 'any one of said members will release the transmitter mechanism from its detent.

In connection with these manually operable members, latchin means is provided for holding them in t e position to which they may be manually moved, and means operated by the transmitter in running is so applied to, suchlatching means that the detent will only be rendered effective to stop the mechanism of the transmitter at the conclusion of the number of cycles represented by the particular manually operaplg member which has been manually opera e The latching means is so applied to the manually operable membersthat none of said members may be moved to the position which will cause the detent to be disengaged from the transmitter mechanism without such member being caught' by its latch.

In the preferred form of this invention shown in the accompanying drawings and hereinafter described, the manually o erof operation of the transmitter than that represented by the member so operated, all of said. memlilers being provided with latching means so applied. that they Wlll be 5. held affair-suchv 'nanual ogeration as will r it in the withdrawal of the transmitter v.tenltand. the disengaging means operated by the transmitter in. running is so applied to said hitching me that at the end ofeach cycle of the operation. of said. trans mitterthe one of said latches will be disengaged which holds the manuallyoperable member then standing in ope ated position which. renresents the greatest munber of cycles. v

For quickly clearing: the trans litter of any ial tofwhich. it has been set and restoring; the manually operable members to their normal position. an Llnlatching means rni'm'ided which. is 'crmnccted to the latching means of all the nnrnually operable memhere except the member which will be last released by the disengaging operated by the running; of the transmitter atthe conclusion of each cycle thereof. so that at the conclusion of the current cycle of said trans-- mitter mechanism.said latching means will be withdrawn from the last of the manually operable memliiers and. the detent rendered effective. and each of the'setting handles provided for adjusting the transmitter to the narticlillar digits desired are connected by restoring mechanism tending to move said setting handles and the parts associated therewith (which will be hereinafter re-= feired to as setting mechanism) to the position representinn an absence of strokes for the digit represented by such setting; n'leclmnism (which position will be herein-- after referred toas theunset positio11.). K A. locating mechanism and a latch. are provided for each. setting mechanism. arranged ,to permit movement of the setting niechaism. away from said unset position and .to

oldsaid setting ,mechzmism: at crn'tain"pointsv ,7

against the tendency of the restoring mechanism. to move said setting mechanism to wa rd its unset position. The unlatching means provided for manu'al unlatching of all but one of the manu allv o arable members of the starting mecln anism is also arranged to siimiltaneously dis engage the locating mechanism and locating latches of all the settihg mechanisms and to unset position, means being pro led for locating mechanism and locating.

bringing said locating mechanism and locating latches llltfl eii'ective correlation wl 11 all of the setting mechanisms are in their unset position.

A separate tripping means is provided for causing the disengagement of the locating mechanism and the locatinglatches "ul'ienever the detent for the transmitter mechanism is moved to its effective position.

Suitable sectors are associated in. suitable relation with the various manual setting mechanisms, together with such rearing and. other mechanism as will suitably control and operate said. sectors and cause the operation of suitable circuit changing means.

In order that this invention may he better umlerstood, the drawingsyannexed. to and forming part of this specification show a form of transmitter embodying the various felsrtures of this invcntiombnt we do not limit ourselves 'to the construction shown, as it 1s evident that the features of this invention may be applied, either separately or in combination with each other, to various other: forms of transmitters and we do not limit ourselves to the construction or-',des1gn oi? parts shown in tlledl'flWlllfiS here nafter described, as the same are given merely for section and with one frame plate removed,

In Fig. 1, 4 is the sector shaft whicheio tends across the transmitter, 5 is the first digit sector which is loosely mounted upon said shaft and is adjustable by means of the left-hand; setting handle 17 shown in Fig. 3, and other similar digit sectors are slmllarly mounted upon the same shaft and provided with corresponding associated parts adapting them to be adjusted by means of the setting handles 17 17 3 and 17; but as the construction and arrangement of the other digit sectors and their associated mechanism may be understood from the illustration and de-.

, scription of the first digit sector and its associated mechanism, in the interests of brevity and clearness, the other sectors and their associated parts are not indicated "in Fig. l, and will only be hereinafter briefly referred to.

The rim of each sector is rovided with a flange which has a series of ratchet teeth 6 cut therein. At the end of the seriesof teeth, upon each of the digit sectors, the flange is cut away. 24 is a flexible pause arm rigidly secured to the pause shaft 28. The free end of this pause arm extends toward and to one side of the sector 5, and other corresponding pause'arms are attached to the same shaft in likemanner and similarly 10- cated with relation to the other sectors 7 is a pause pin extending from one side of the sector 5 and adapted to engage with and operate its associated pause arm 24 when the sector is in a certainposition. The pause arm 24 is shown as being rendered laterally flexible by constructing it from thin'material, as indicated in Figs. 10 and 11.

' The shaft 8 shown in Fig. 1 extends across the transmitter below the sector shaft 4, and

I in suitable relation to each sector there is mounted upon this shaft a sector spring 9 which is so constructed and'applied that the force tending to move the sectors in clockwise direction is practically constant at all times, whether this force is mainly due to the weight of the sector when its center of gravity is to the right of its point of support, as shown in Fig. 1, or to the increased pressure of the spring when the sector is in a position where its center of gravity has been moved to the left, due to themovement of the sector in counter-clockwise direc tion.

For adjusting each of the digit sectors, a setting arm 10 is so mounted upon the'shaft 4 that a portion of said arm will lie in the The barriage ll Shown in Fig. 1 is provided for controlling the position of the set- 'ting arm 10 cotiperating with sector 5 and is operable by handle 17, similar carriagie s being controlled by setting handles 17 1 and 17 Eachof the carriages is adapted to move upon a suitable vertical guide, the vertical guide 12 shown in Fig.1 being provided for the carriage 11. i

Each of the carriages is connected with a 'revoluble drum 16 by means of a flexible ribbon 15, and each drum is equipped with a restoring spring 16*, tending to rotate such drum in a direction which will raise the carriage. In Figs. '1 and 14, the dial13 is shown, said dial moving with said drum 16.

The shaft upon which the drums are mounted is secured against rotation and the drums are looselymounted thereon, and suitable indicating numbers are provided around the periphery of each dial 13. In suitable relation to these numbers openings are pro-- vided in 'the front plate 14 (see Fig. 3), so

that when anysetting' handle is adjusted for a certain figure, the same figure upon its dial will be presented to view through the open.- ing in the front plate.

The restoring spring 16 is suitably con nected between the drum 16 and its shaft and is of such strength that it will raise the carriage, 11 and connected parts against the force of gravity.

.In suitable relation with each carriage is provided a rack plate 20 having ratchet teeth 19, and a locating latch 18 is mounted in each carriage for engaging the teeth of said rack plate, the construction and arrangement of these parts being shown in Fig. 1, in which the rack plate 20 is shown as being mounted in suitable relation to the carriage 11 and is adapted to be engaged by the locating latch 18 carried by said carriage 11.

Y The ratchet teeth 19 in the rack-plate 20 are of such form as to arrest the movement of the carriage in one directoin but to permit it to be freely moved in the other direction. The spring 18 tends to hold the locating latch 18 in the path of the teeth 19, but this latch may-be withdrawn from the path of said teeth by means of the rod 11, which is loosely mounted in the carriage 11, and may be operated by the.setting handle 17 Th engagement between latch 18 and. the rod 11 is such that the latch 18 may vibrate in passing over the teeth 19 without moving said .rod 11, but the rod 11. may be pulled forward by means of the handle 1.7 to a point where it will withdraw the latch 18 plate 20 swung out of the path of said latch 18. said latch will. be moved by the spring 18 past the bottom of the notches of the teeth 19 and thereby prevent said rack plate 20 swinging-t0 a position which will bring the teeth 19 into the path of the latch 18 until the carriage 11 moves to a point which brings said latch 18 opposite the notch 19, when, owing t6 the extra depth of 'notcl'l 19*, said latch 18 will no longer obstruct the nmvement of the rack plate 20.

7 Suitaliule supports 21' extend across the tram n'litter above and below the rack plates 20, said rack plates being pivotally mounted.

latches 1S cooperating therewith, and to plate thereby form disengageable locating'mechanism.

A link 1253 forms a connecting means for the free of the rack plates 20, and an extension of said link is" provided with a notch 126 (see Fig. .A spri 'lg 150 "with the link and tends to more and link in the direction which will bring t 1e rack plates 90 in the path of their codpemting forming means tending to adjnst the locating n'lechanisni to engaged posltion. A bracket 197 ismonnted on. the frame a shaft 128 being journaled in ct and carrying the arm 129.

- mounted a pin 130 adapted to engage the notch 126 also J I The arm 1.31 (see Fig. 13) is included upon the shaft .128 and moves with the arm l 129. An arm 132 carried by the shaft 128 and moving with the arm extends, atone side of and past the rod 100. Adog 133 {see Figs. 2 and 12) is pivoted at inv the rod 100 in editable relation. to the arm 139, so that the free end pf said do may engage said arm at. certain times thereby forming tripping means for the disengage able locating l'nechanism, and a stop-pm 135 is mounted in the path of the tail 136 of the dog 1533, thereby forming disengaging means y d tripping means, said tail. being so shapr that v'vhen the rod 100 is in the'position. shown in Fig. 2, the free end of the dog locating latches 18, tl'iereby,

3 in suitable :relatioi'i to the notch 126 the free end of the arm 129 133 will be held out of the path of the arm 139. A spring 137 carried by the rod 100 is so applied tothe' dog 133 as to tend. to 'swin the free end of said dog into the path 0% the arm 132. y y A three-arm bell crank 138 (see also Fig.

9)is pivoted at 139, a spring 140 being so, applied to one arm of-said bell crank as to.

tend to swing said arm against the st0p-pin said bell crankwith the arm 131 carried by the shaft 128 theslot 143 in the end of said A link .1412 connects another arm "of link heingiofsuch length'as to permit the arm 131 to move far enough to swing the rock plates 20 out of engagement'withtheir cooperating latches 18, without moving the bell crank 138. v

A rod 144 is mounted at one end in the bracket 145 to slide freelytherethrough and the other end of said rod is-pivoted to an arm of the'bell crank 138. Pins 146 are mounted in the rod 144 in suitable relation to the latch dogs 109 sothat when the rod 144 is moved downwardly, suitablepor t1ons of the latch dogs 109 will be en'- gaged by their associated pins 146, and said latch dogs will be thereby disengaged from their cooperating latch arms 108.

The pin 146 mounted on the rod: 144 near the latch. dog 109 is so short that said pin may pass said latch dog without enga 'n therewith see Fig. 16). g1 g arms 108, the bar 1 12 will be moved out'o fthe path of its cooperating lug 111 before the latch dog 109 commences to rise in respouse to such. Increment of the rod 144.

The rod 148 is mounted in the plate 14 to pass freely "therethrough and one end of said rod is pivoted to the arm of the bell crank 138 to which the link 142 ispiv oted,

and the other end; of said r0d148is pro 1 vided with the unlatching button 149. p

The teeth 19 (see Fig, 1) aresdspacgd as to be adapted to hold the carriage 11" opposite any one of the indicating marks provided on the front plate 14 (see Fig. 3), an extended blank space being provided above the tooth correspo ding with the upper indicating mark, an a corresponding extension of the'slot iiithe front plate above this mark being provided to permit the carriage 11 to move upward far enon h to bring the pause pin 7 to the left of t e free end of the pause arm 24 (as shown in Fig.1) when the carriage 11 has not been. moved down far enough to permit the latch 18 to engage with any of the. teeth 19. and.

the deep notch l9 is located in such position that it will be engaged by the locating latch 18 when the carriage is in such highest or unset position, the other carriages, rack plates, slots and cooperating parts be ing similarly arranged.

The carriage 11 and setting arm 10 are shown in solid lines in Fig. 1 in the position they would occupy when adjusted for the transmission of ten strokes, and these parts areshown in dotted lines, in the same figure, in their normal or unset position.

The mechanism for actuating and holding the various sectors being substantially alike, and as a showing of all these parts in one figure would unduly complicate the drawing, Fig. 1 only shows necessary parts for to operation with the first digit sector 5, and it will be understood that the following description of parts cooperating with sector 5 correspondingly applies to equivalent parts provided for cooperation with the other digit sectors.

The shaft 25 extends across the transmitter and has loosely mounted thereon a re taining pawl 22, having a projection adapt-' ed to engage with the teeth 6 carried by the sector 5.

An eccentric shaft 27 extends across the transmi ter and bears suitable eccentrics 26, one of which is mounted in suitable relation to each of the sectors. The eccentric arm 23 is mounted upon eccentric 26 and said arm is provided with a lifting pin 29, of such length as to reach past the retaining pawl 22 and be adapted to be engaged by an arm mounted beyond said retaining pawl 22 (see Fig. 8). An opening 22 isprovided in the retaining pawl 22 in such position and of such shape as to permit the lifting pin 29 to reciprocate freely therein.

A projection is provided near the free end of the eccentric arm 23 which is adapted to so engage the teeth 6 on sector 5 that upon the rotation of eccentric 26, the sector 5 will be rotated in counter-cloclnvise direction against gravity and the pressure of spring 9. The construction of the retaining pawl 2:2 and the opening 22 therein is such that when the sector 5 been moved by the eccentric arm 23, the action of this retaining pawl will prevent the sector from moving in the oppositedirection during the return stroke of the eccentric arm.

The throw of the eccentric 26 is such that the arm 23 reciprocates through a distance greater than the distance between any two of the teeth 6, but not so great as twice that distance.

For the purpose of successively rendering effective the retaining pawls and eccentric arms for the various sectors, an actuating arm 57 (see Fig. 5) is mounted by the side of each retaining pawl, all of said actuating arms being so connected as to move together,

ciated with its sector will remain in cl -tion, one of the sectors may be end of the one of these arms which cooperates with, the retaining pawl associated with the sector which may be adjusted I the setting handle 17 -is held on a plane with the top of said sector, the free ends of the actuating arms associated with the other seetors will be a suitable distance above the tops of said sectors, and if the free end of the actuating arm 57 associated with the retaining pawl which cooperates with the tor which may be adjusted by the setting handle 17 is held on a plane with the top of said sector, the free ends of the actuating arms associated with the sectors which n12" be adjusted by the setting handles 17" and 17* will be a suitable distance above the tops of said sechgs, and the same will be true of the relation between the actuating arms as sociated with the sectors which may be adjusted by the setting handles 17 17".

A lug 58 extends over the portion the teeth 6 which are cut upon the flange of the sector 5 (as best shown in Fig. 8), and the purpose of this lug is to support the 57 of which it forms a part, so long as the flange of its cooperating sector lies within its path.

Similarlugs are provided upon each of the actuating arms, so that while any given sector is being moved in counter-clock se direction (Fig. 1), its flange willcause its tors will be held out of engagement with the teeth thereof; but as soon as the movement of the actuated sector has brought its f 7 out of the path of the lug of its coopc -ng actuating arm, such arm will be permitted to drop and thereby bring the actuating and holding mechanism for the sector located next to the right into o; )erative c mdition.

It is evident that after any actuatn r 57 drops below the plane of the rim 1 sociated sector, the retaining pawl ire position until such actuating arm 5?" raised to a plane above its associated flange and therefore said flange will be held out of the path of the lug or its actuating arm until 7 said arm-has been so raised.

For the purpose of measuring the sii nt interval immediately preceding each re eti.

' w.dec'f with additional pause pins and herein shown a sector is provided which not subect to the control of any of the setting handles or carriages, but having a plurality of pause pins and acqustable means for rendering a greater or smaller number of said pause pins effective so that the duration of this silent period maybe suitably adjusted.

This additional sector is shown in Fig. 9 and comprises the sector 77 pivoted on the shaft 4 and provided with a spring 9 act 'ing in like manner to the springs 9 appliedto the digit sectors.

A downwardly extending arm 78 is carried by the sector 77 and' the free end of this arm is adapted to engage with the shaft sector 77 is moved eonliter-clockwise, one of these pins will raise and support its cooperating pause arm 24, and thereafter the continued movement of the sector 77 counter-clockwise will ca use other pause pins to successively support said pause arm; a snflicientnu nber of these pins being provided to produce the longest silent period for which it may be desired to adjust the transmittcr. v 1

An arm Si'is mounted in suitable relation to the sector 77 and is provided at its free end with a series of HOtCllLH 88 spaced at the,

same angular distance as the teeth of the sector 77. v

A roller 8%) is suitably mounted near the free end of the arm 87, for a purpose hereinafter described;

A spring-l0 is scoured lo the sector 77 by means of the screws or rivets 91., and a block 92 is secured to the spring 90 near the l'rceend thereof, said block bcingada}' ted to engage with any one of the notches 88, and the free end of said spring is so formed as to facilitate manual disengagement of this block from said notches "lhe eccentric arm 23 is similar in conv struction and operation to the eccentric arm 23 already dcscrilwd.

The retaining pawl 22 is similar in construct-ion to the retaining pawl- 22 already described, and is pivoted on the shaft25.

Alatch 79 is pivoted on the, frame at 80 and comprises the bell crank arms 81 and 82, the arm 81 being provided near its free end witha ledge from the end of which a slanting face extends to the end of saidar'm.

A pin 83 is mounted upon the retaining pawl 22* in such relation to the ledge carried by the arm 81 that said ledge may engage with this pin and thereby support the retaining pawl 22 out of engagement with (the teeth ofthe sector 77 and carry the co- "cl-atria arm 23 by means of its lifting pin- 29 out-"tilt: el'lgagement with said teeth.

dgspring f l-tais so applied to the latch 79 ias to tend it move the arm 81 of said latch v toward the pin 83, thus bringing the ledge under said pin whenever the pin is above said ledge and tending to hold the retainin pawl 22 in engagement with the teeth 0 the sector 7 7 by means of the slanting face when the pin is below the ledge.

The arm 82 of the latch 79 extendtoward the shaft and is of such form as to adapt it to be engaged by an arm carried by said shaft 25 so as to more the arm 81 away from the pin Pin 93 is mounted in the pat-h of the arm 81 and is adapted to restrict the movement of said arm away from the pin 83. y

A resetting lever 85 is secured to the shaft 25) to IUUXG therewith and the free end of said lever has a slanting face adapted to 'be moved in the path of a .pin 86 carried by the eccentric arm 23 and so formed that when said face is in the path of said pin and U the eccentric '36 is in one position the eccentric.- arm 23 may engage the teeth of the sector 77 but when said eccentric 2G is in another position the slanting face of-the lcvcr 85 will hold the-eccentric arm :13 high enough to cause the lifting pin '29 to raise-the retaining pawl :22 high enough to bring the pin 83 above the the arm. 8i and thereby bring both'the retaining pawl and eccentric arm out of engagement with the teeth of the sector 77.

The lower face of the lever 85 has formed thereina cam face 151 and a shoulder 153 adapted to be engaged by the roller 89 to' be moved thereby so that when the roller ledge carried by? will raise'the resetting-lever'85 to a point where the pin 86 will not be operatively atl'ected by the slanting end of said reset-ting lever 85; and the lower face of said lever 85 between the shoulder 15;] and the 0am face L31 has a radial surface 152 adapted to maintain said resetting arm 85 in the position to which it is raised by engagement of the roller 8!) with the shoulder 153 durin' the movcment-ot'the sector 77 re )resente by one of the. teeth of said sector, w ereupon said roller 89 w-ill be brought into engageanent with the canr'facelfil and the movement of the sector 77 represented by the next' tooth thereof will so raise the lever 85 as to bring the slanting face of the free end thereof into the path of the pin 86. The upper surface of thelever 85 isshown cut away so that when this lever hasbeen oted. on the frame at '75 and is provided wit an extension having two ledges adapted to cooperate with the pin 73 carried by the actuating arm 57 which cooperates with sector 5 associated with setting handle 17 These ledges are so positioned with relation to the pin 73 that when sald pin is supported by either of these ledges, the arm. 57 and assoclated arms will be held in such position'that the retaining pawls and eccentric arms associated with the se -tors will be held out of engagement with the teeth thereof, and said ledges are located one aboveflthe other so that when the upper ledge is withdrawn from supporting the pin '73, the movement of the actuating arm 57 -may bearrested by the engagement of said pin 73 with the lower ledge before said arm 57 has dropped far enough to bring any of the retaining pawls or eccentric arms into engagement. with their cooperating sectors.

An arm 76 of the latch 74 extends in the path of the lifting pin 29 carried by the eccentric arm 23 coiiperating with sector 5, the arm 76 being so formed that when the pin- 73 is supported by the upper ledge of the latch 74, the throw of the eccentric 26 will cause the eccentric arm 23 to move the pin 29 against the arm 76 and swing the latch 74 around its pivot 75 far enough to disengage the upper ledge from the pin 73, but the end of the arm 76 is provided with a ledge which will support the pin 29 and thereby prevent the eccentric arm 23 from dropping with the actuating arm 57 when the pin 73 is thus disengaged, and the portion of the arm 76 above said ledge is of such form'that the throw of the eccentric arm 23 will not move the latch 74 far enough to withdraw the lower ledge from the path of the pin 73 while the pin 29 is supported by the ledge carried by the arm 76. v

The face of the ledge carried by the arm 76 is of such length that when the eccentric 26 has drawn the arm 23 to the position which carries the pin 29 farthest from the arm 76, said pin 29 will be carried beyond.

the end of said ledge and will permit the eccentric arm 23 to drop down far enough to bring the pin 29 in the path ofa projection.-

carried by the free end of the arm 76.

The projection carried by the free end of. the arm 76 is of such form that when the pin 29 is moved by the rotation of the eccentric 26 against the end of this projection, the lower ledge carried by the latch 74 will be withdrawn from the path of the pin 73 and the actuating arm 57 will be permitted to drop, carrying the pin 73 out of control of the latch 74 The portion of the latch 74 carrying-the ledges engaging with the pin 7 3 must be so proportioned with relation to the pin 29 that said-portion of the latch 74 will not interfere with the free movement of the pin 29.;

The lever 85 (see 9) is secured to the shaft 25 in such position with relation to the actuating arm 57 coiiperating with the sector 5 that'when the lever 85 has been raised to its upper position said actuating arm 57 will be so raised as to carry its pin 73 above the upper ledge of the latch 74.

The arm 94 is so located upon the shaft 25, with reference to the actuating arms 57 carried by said shaft that said arm 94 will not engage with the arm 82 while any of the arms 57 are supported by their coiiperating sectors.

A suitable governor (see Figs. 1 and 2), indicated by a characteristic representation of a fan, is mounted-upon the shaft 33, and said shaft is connected by gearing with the shaft 32, which is, in turn, geared to the ec= centric shaft 27. The cam shaft 34 is geared tothe shaft 36 and to the, shaft 32.

Only the pitch lines of the various gears are shown, the arrows indicating the direction of motion of the various shafts.

The releasing cam 40 is mounted upon the cam shaft 34, and is shown as having four lobes, and the ratio of the gearing between cam shaft 34 and eccentric shaft 27 is shown as 1 to 4. The ratio of this gearing to the form of this camshould, in all events, be such that one lobe-of this cam will pass a given point upon each revolution of the ec centric shaft 27.

The releasing arm 41 is pivoted on the frame at 42 and is provided with a .;roller adapted to bear upon releasing cam 40.

The angular relation of the releasing cam 40 to the eccentrics 26 should be such thit't the releasing arm 41 is raised and allowed to drop while the eccentric arms are passing through their idle stroke.

stud upon the detent lever 45 and the free end of id bar extends in the direction and to one side of the releasing arm 41 when' the transmitter is at rest, as shown by dotted lines in Fig. 2.

The releasing pin 43 is mounted on the releasing arm 41 in a. position adapting it to engage the free end of releasing bar 44.

The releasin bar actuating arm 47 is mounted upon t e pause shaft 28, and moves with the pause arms 24 'which are also mounted upon said shaft, :fiis arm 47 being of such len h as to apted to move the free end '0 releasing bar 44 into or out of the ath of releasing pin 43.

The ink 46 is loosely connected to the free ends ofthe releasing bar 44 and the releasin bar actuating arm 47, said link 46 being 0 such length that when any pause pin 7 on any sector hasbeen movedgunder and has'thereby raised its ause arm 24, the free end of the releasing. ar 44 will be moved out of the path of the releasing A stop pin 35 is mounted on the frame and pro sets in the path of the releasing bar actuating arm 47, in such position that when the pause pins on the various sectors are Withdrawn from the snpport of their operating pause arms, the r-citation of the shaft 28, resultirig from the weight of the. pause arms, will be arrested when the free end of the releasing bar 44 has been brought into the path of releasing pin 43.

The arm 95 (see Fig.9) is fixed upon the shaft 28 in such position that a pin 96 mounted in the free end of said arm may be engaged by the arm 94 so as to rotate the shaft 28 to the point which will carry the releasing bar actuating arm 47 clock wise (Fig. 1) far enough to move the releasing bar 44 out of the path of the pin 43 whenever the roller 89 has raised the lever 85 to its upper position.

The rotation imparted to the shaft 25 when the resetting lever 85 is raised by the roller 89 passing underthe shoulder is such as will raise all of the actuating arms 57 far enough above the rims of their eoengaging sectors to carry the projections of the eccentric'arms 23 and retaining pawls 22 associated with said actuating arms above the path of the ratchet teeth 6 of their associated sectors, and when the resetting lever 85 is raised by the roller 89 passing under the cam face 151 the rotation of such,

shaft is such as to bring the pin 73 (see Fig. 5). above the upper ledge of latch 74 and thereafter said latch '74 will prevent the pin 73 from dropping far enough to allow the shaft 25 to turn far enough to sufficiently withdraw the support of the arm 94 from the arm 95 to permit the shaft 28 to turn far enough to bring the free end of the releasing'bar 44 into the path of the releasing pin 43 so long as said pin 73 is above either of the ledgesforined in the latch 74.

.When therack plates 20 were thus-swung out of the path of their cotlperating locatmg latches 18, the springs 16" a'cted through the ribbons and raised the carriages 11 10 associated with the setting.handles 17 17 and 17 to their unset position, thereby bringing theirassocisted locating latches l8 4 opposite the-deep teeth 19 of their asso- "mated rack plates and permitting said rack 1 l5 fplates to swing into the path of said looat inglatches in response to the tendency of the spring 150, and thus all Y transmitter were restoned to t eir normal or unset position. 20 If the signal had been initiated by presslug button 39 instead of button.39 the operation of the transmitter would he as already described except in the following re- -spects:-

When button 39 was pressed toward the. front plate 14-, carrying rod 101 with itfthe engagement of the interlocking block 105* mounted on said rod 101 with .the block 105 mounted on rod 101 would .have' 80 caused said rod 101 to move with the rod 101' and the rods 101 and 100 would like have'been moved by their interlocking blocks 105? and 105 mounted thereon-so that the rod 85 to swingthe lever 37 and withdraw the de tent 115 from one of thepins 38-,j1ist as already" described. r

The movement of the rods 100, 101, 101 and 101 would have been communicated to 'inions 106 associated with the racks 102 ormed in said rods to rotate the shafts 107 associated with said pinions (see Fig.

2) and thereby swing the latch arms 108 to the position shown by solidlines in Fig. 9,

said latch arms being turned to the point where the shoulders of theirassociated latch dogs dropped in front of them justprior to the lever 37 reaching. the point initsimovement where it caused; the disengagement of the detent-l'lh from its associated pin 38.

The movement of the latch arms 108 just described would cause said arms to engage the extensions 113 of the detachable bars 112%, 112 and 112 and thereby swing said' path or" their co-engaginglugs 111."

After the disengagement of the detent 115 from its associated pin 38, 'thedetermining train would operate asalready described to cause the release of the transmitting train to formulate the digits 3 -2-4 and after a suitable interval after the last stroke during which the transmitting train remained at rest, the movement of the sects tor 77 would bec mmimicated to the arm arts of the- 100 would have been caused 100, the detent 115' would not 110 so that said arm would be brought in engagement with the latch dog 109 and would first lift and then drop said dog, thereby completing one cycle of the opera tion of the transxmtter'.

The operation of the various parts from the disengagement of the djetent 115 to the lifting of the latch dog 109, would be identical with that described for the operation of the transmitter when the transmission of itsfsig'nal was initiated by pressing the but but as their tton 39' would have now been pressed an-l the detachable bar 112 would have beennioved out of the path ofthe lug 111 carriedby said latch dog 109,}, the lhtch dogs 109 109 and 109 would not be afi'ected by this lifting of the latch dog 109* but the lifting of saidlatch dog 109 would disengage it, from its associated latch arm 108 and ermit the starting button 39"to be move away from the front plate'l t by its restoringspring 99 audthereby' turn its associated pinion 106, shaft 107 and latch. arm 108 to the position shown in Fig. 2 by solid lines and in Fig. 9 by dotted lines,- thereby carrying said. latch.

'cycle'of operation of the transmitter, the

detachablebar 112 would be swung by the force of gravity into the path of its asso-- oiated lug 111. 100 Inasmuch as the movement of the rod, 101 just described would not afi'ectthe rod v be-brought in the path of the pins 38 and the running of the determining train' would-continue and 105 the digits'3-2-1 would again formulated by the transmitting train and after a run of the determining ftrain thereafter without releasing the transmitting train represented by the travel of sector 7 7 the movement of said sector 77 v muld-be. again com- Inunicated to thearm 119 which would in" turn, first raise and then drop the latch dog 109%, thereby completing the second cycle of the operation of -said transmitter,

This lifting'of the latchrdog 10,9 would be communicated through its lug 111 and" the detachable bar 112 -to the latch (108109, and would thereby dpermit thestartin gbut ten 39 to be'move "14 by its spring 99.

The latch arm 108 associated with button 39 would thus swing out of the path of extension 113 of detachable bar 112 and said 1 bar would be permitted to swing into-the 1 path of the lug 111 carried by latch dog 109. At the end of the third cycle of the operation of the transmitter the parted tolatch dog 1-09? by arm 119 would be, likewise imparted :to' latch dog 109 through 1 0 movement ima ay from front plate 120,

If it is desired to formulate a signal of more than ten consecutive strokes, as, for example, sixteen (16) strokes, the setting handle 17 should be moved slightly below the indicating mark numbered 10 and the setting handle 17 should be moved slightly below the indicating mark numbered 6, whereupon the dials associated with said handles will indicate 10-6, as shown in Fig.- 3, and the sector 5 associated with the setting handle 17 would be swung forward twelve teeth and the sector associated with the setting handle 17 would be swung forward eight teeth.

The coupling handle should now be lifted from its ofi position to its on oint consisting of the arms and 66 (see Fig. 1) and'thereby raising the arm 68 and swinging the arm 70 by means of the links (39 around its shaft 28. I

Such lifting of arm 68 would swing the sector 5 associated with the setting handle 17 back one tooth by means of the pin 71, and the swinging of the arm 70 would, by the action of its slanting face 72 upon the pause arm 24, swing said pause arm out of the path of its associatedpausepin 7 (see also Figs. 10 and 11). y

The transmission of the signal may now be initiated by pressing the desired one of the starting buttons, and during each cycle of the operation of the transmitter incident to the formulation of the signal soinitiated, the operation of the various parts would be:

the same as already described cxceptthat the pause pin 7 carried by the sector 5 asshciated with setting handle 17 its associated pause arm 24, and therefore the series of circuit changes'formulated by the transmitting train would be continuous during the movement of the sectors associatedwith said setting handles 17 and 17.

Through the use of the coupler mechanism the pause pin 7 associated with setting handle 17 would be thus-rendered ineffective,

' act to hold the would not engage 1 be included with the arm 12 but if this alone were done it would not only cause an uninterrupted series of circuit changes to be formulated by the transmitting train, but such series would comprise one more stroke than would have been formulated had this pause pin been effective. For this reason, the sector 5 associated with setting handle 17 was the arm 68 acting againstthe pin 71 when the coupler handle 60 was raised so that the number of teeth of the sector 5 associated with said setting handle 17 in front of the projections of their co-acting ecc en tric arm 23 and retaining pawl 22 was reduced from twelve to eleven.

When the coupler handle 60 was raised as just described, the guide 61? was swung in the path of the bar 62 so that when the rack plate 20 was swung out of the path of the latch 18 associated with the setting locatlng handle 17 and its carriage 11 was thereupon lifted bythe restoring spring 16 actraised one tooth by.

ing through the ribbon 15, said bar 62 acted and inasmuch digits of eleven strokes or excess of ten strokes, the guides 61 and 61 off posit-ionexcept when the setting handle 17 has been moved to its 10 position. It is therefore necessary to move said handle to its 10, position before the coupler handle can be moved to its on position.

If the setting handles 17, 17 17. and 17* or any of them have been adjusted for the formulation testing or demonstrating the transmitter), and it becomes desirable to quickly clear the transmitter from such I tobe set for some other signal, although this result can be accomplished by withdrawing each of the locating'latches '18, one aft'er another, from its to its unset position, or to the position to which it coupler handle locked in its of some signal (either for setting and adapt it associated rack plate 20,-. by pulling its associated setting handle away .from the front plate 14 and holding Said sired to set such handle-for the urgent sig-- nal, it is evident that if one of the setting handles which hadbeen adjusted for the demonstration or test was not needed for the urgent signal, such handle might be overlooked, and through remaining as originally set, might the urgent signaL. It is therefore preferable, under these eircum stances, to press the unlatching button 149, thereby so moving the rod 148 and link. 1&2 (see Fig. 9 as to swing the arm 131 and associated therewith to a point cause an unintended digit to
