' TRUSTEE, OF BOSTON, -MASSACHUSETTS.

J'ALPPAERATUS Fort SENDING mnnnomvme INFORMATION.

To all whom it may concern:

Be it known that I, EDWIN V. HAGMAN, a citizen of the United States, residin at Boston, in the county of Suffolk and tate of Massachusetts, have invehtedan Improve- I ment in Apparatus for Sending and Receiving Information, of which'the following is aspecification. t

This invention relates to apparatus for communicating definite information from one point to another by electro-mechamcal means. It is especially desirable for transmitting ranges from abridge, conningtower, or other station on a war vessel to the various gun-stations, and will be hereinafter described in that connection, although its scope is notv limited thereto. With slight variations theapparatus, hereinafter to be described, may be used for transmitting dehaving hand-actuators for the circuit-controlling means, one for sending the ranges,

say fromO to 950, in increments of 50, and the other for sending, ranges, say from 1000 to 19000 inclusive, in increments of a 1000,

I either one or both being employed as oocasion demands. One of the hand-actuators may be arranged at one end of the instrument for operation by the right hand and the other may be arranged at the other end of the instrument for operation by the left hand, although such arrangement is not material. A motor is provided at the gunstation of receiving-station which is associated with the register, by which the register is operated'to set up different numbers,

as for instance, by rotarily moving numberdrums on the peripheries of which the numbers are arranged. The motor is of the rotary type and arranged for operation in either direction and the register is also of the rotary type and arranged for operation in either direction, so that when setting up Specification of Letters Patent. Patented Aug. 20, 1918. Application filed May 13,1914.- swarm. 838,254. I I i a number, the motor and register may be moved rotarily through the shortest arc to arrive at the number to be setup on the register, thus saving much time. The number-drums of the register are arranged for movement by a mechanical connection with the motor shaft.

Numerous controlling devices are provided for the transmitter, some of which are arranged for operation by means associated with the motor, and others by means associated with the register, and others by component parts of the transmitter, and said controlling-devices are so arranged as to cause all movements of the apparatus to be performed in a prearranged order, for the correct sending and receiving of the signals,

otherwise the signal will not be sent, or if sent, the fact will be made known that it was not received.

Fig. 42 is a fragmentary detail of a portion of the motor The component parts of the range-register, see Figs. 21 to 31, are arranged in a case 200, having an opening or window 201, at the top, through which the rangenumbers are visible. The right hand or unit-number 202, is zero. and is mounted on a stationary member or dummy. The tens numbers are carried by a movable target 203, which has arranged thereon two numbers only, viz :0 and 5, because the variations in the range-numbers are, for convenience, by increments of fifty, and one or the other will therefore be brought into visible position by a movement of the target. A similar target 204 is arranged for the F tens of thousands numbers, which has arranged thereon two numbers only, viz :0 and 1, as the range-numbers will not ordinarily reach 20,000, and one or the other number will be brought into visible position by a movement of the target. The

periphery of a rotary-drum 205, loosely mounted on a shaft 206, and the thousands numbers are arranged on the periphery of a rotary drum 207, also loosely mounted on said shaft 206, and each of said drums has numbers ranging from 0 to 9. By this arrangement any number from 00000 to 19950, var ing by increments of fifties, can be broug t into visible position.

The numbers on the number-

drums

205 and 207 are equi-distantly disposed throughouttheir entire circumferences, and hence they are each designed to be moved into ten predetermined positions to bring their different numbers into visible position. To rotate said drums each drum has fixed to it a toothed gear, as 208, 209, and said gears respectivel engage toothed driving-

gears

210, 211, t e gear 210 being secured to the inner end of a sleeve 212, and the gear 211 being secured to the inner end of a sleeve 213, and said sleeve being arranged in alinement and both supported loosely on a shaft 214 and spaced apart. to revolve on said shaft as a bearing.

It is herein designed to employ said shaft 214 as the driving-shaft for both drums, and to employ a single motor for rotating it. Therefore means are provided for clutchingthe driving-gears '210 and 211,

29 to 31, a clutch-sleeve 215 is slidably mounted on and keyed to the shaft 214,

. which sleeve is movable axially by a clutchlever 216, engaging a collar 217, on said sleeve in usual manner, said lever being fulcrumed at 216. The clutch-sleeve or mem-- her 215 has on one side of it a projection 218, arranged to enter a hole 219, in the gear 210, thereby to connect the clutchmember with said gear, and said projection bears a roller 220 for engagement with the face of said gear 210, in case said gear is not disposed with its hole 219, in register with the projection 218, at the moment the clutch-member is moved toward the gear for engagement therewith, thus permitting free rotary movement of the clutch-member with the shaft until engagement is effected. The clutchsleeve has on the other side of it a like projection 221, arranged to enter a hole 222 in the gear 211, thereby to connect the clutch-member with said gear, and said projection bears a roller 223 for engagement with the face of the gear 211, in case places whereby said gears hold the number-drums with their zero numbers exposed -the driving-gears, thus to hold them in different predetermined positions, and such means, as here shown, conslsts of a, horizontally arranged bar 224, pivoted at a point 224' intermediate its length to the clutch-. lever 216, and having pivotally connected to it at each end an

upright lever

225, 226, said levers being pivotally connected at points between their ends at 227 to a stationary bar 227', and their-upper ends arranged for engagement with any one of a plurality of pairs of projections 228, arranged on the sides of the driving-gears, there being as many pairs of projections as there are numbers on the drums and arranged at the proper places, so that when either locking-lever is in engagement with any pair of projections, a number corresponding to the location thereof will be exposed to view. Y

A spring 229 is connected at one end to one of the locking-levers and at the other end to a fixed point which acts to move both locking-levers and also the clutch-lever in a direction toward the left, F ig.-22, thereby to move the clutch into engagement with the driving-gear 210, and the locking-lever 225 out of engagement with said driving-gear 210 and the locking-lever 226 into engagement with the driving-gear 211, but it'Will be understood that the spring may be otherwise arranged to thus move all of said levers, the object being to employ a spring to impart a movement toall of said levers in one direction, and to employ other-means, as will be hereinafter described, for imparting movement to them in the other direction. When said levers occupy the positions thus shown and described they are in their normal positions and the number-drum 205 is connected with the driving-shaft through the driving-gear 210, and said driving-gear is unlocked and free to be rotated, and the number-drum 207 is disconnected from the driving-shaft, (its driving-gear 211 being disconnected from said shaft) and said driving-gear is locked in position, so that it will be held against rotation or tendency to rotate by rotation of the driving-shaft on which it is mounted. Upon movement of the clutch-lever in a direction toward the right, Fig. 22, first the clutch-member is disengaged from the driving-gear 210, and is moved against or into engagement with the.

driving-gear21l, and the locking-levers are also moved in the same directionand in the following manner :tha't--is to say, whenthe clutch-member has disengaged the'driving-gear 210, both driving-gears are then disconnected from the driving-shaft, and

' both locking-levers are in engagement with the respective drivin -gears, the lever 225' having been moved ar enough to engage the driving-gear 210, and the lever 226 having been correspondingly moved yet still remaining in engagement with the drivinggear 211, so that when the clutch is in its -middle position both driving-gears are positively held by their locking-levers; then upon further movement of the locking-levers 1n the same direction the locking-lever 225 is moved into further engagement with the -dr1v1'ng-gear 210 and the locking-lever 226 is moved out of engagement with the driving-gear 211.

The'return movement of all said levers from the positions into which they have thus been moved to their normal positions is in a like manner, and it will be noticed that during such return movement both driving- I gears are locked by the locking-levers while the clutch-memberiis in its middle position and 1: isengaged from both driving-gears. The middle position of the clutch-member when moved in either direction is utilized for it will be seen that in case the drivinggears are so relatively disposed that their holes 219 and 222 are not directly opposite each other, then the clutch-member when moving out of engagement with a hole in either driving-gear Will move up to and against the face of the other driving-gear, w 1ch is its middle position, and will remain 1n continuousengagement with the face of said driving-gear while and during the time it is being rotated by the driving-shaft and until it has been turned far enough to permit one of its projectionst'o enter the hole in the driving-gear against the face of which it is for the moment being held. Further reasons for this arrangement will be herein after described. v

Movement of the clutch and also of the locking-levers is arranged to be controlled from the sending-station, and, as here shown,

spring 232, or other means, with one of the locking-levers, as 226 for instance, and said relay is normally deenergized, and when energized and its armature attracted "the spring 232 will be extended and the lockinglever movedon its pivot, and, as said lever is connected with the other locking-lever and also with the clutch-lever, all of said levers will be moved at the same time by said relay.

The motor which is employed for driving the shaft 214, is or may be the same as shown and described in my application Serial No.

838,255 filed May'13, 1914.

. Referring to Figs. 32 to 35 and 37 to 42 5 wherein the motor is illustrated, 38 represents a toothed-gear arranged in front of and in engagement with a toothed-gear 38, on the driving-shaft 214 of the register and said toothed-gear 38 is secured to the motorshaft 20, which shaft is rotatably mounted and is free to rotate in both directions, thereby to rotate the driving-shaft 214 in either direction and correspondingly rotate. the number-drums. It is a distinct advantage to provide a motor having the capability of rotating its shaft in either d1rect1on as t enables the number-drums to be rotated in either direction, whereby they may be moved to different predetermined positions through the shortest arc, as contrasted to being moved always in a forward direction and thereby consuming a large amount of tlme 1n mov1ng through a long arc. To accomplish this result a crescent-shaped armature 36 1s secured to a support 30 arranged on the motorshaft, and said support is also made to serve as a counterbalance for said armature, whereby said armature will have a tendency to remain in whatever position it may be set. A plurality of electro-magnets are arranged circumferentially about the motor-shaft, and are equidistantly disposed, ten such magnets being here shown, which are designated by the

numerals

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and the end-portions of the cores of said magnets at one end thereof, are made to serve as the pole-pieces of the magnets. The crescentshaped armature is here shown as arranged to enter the fields of all of the magnets, so as to be influenced by any one of them that may be energized, and will be moved upon energization of any of said magnets to bring its middle or thickest portion into the field of the energized magnet, thus to rotate the motor-shaft and in turn rotate the drivingshaft 214 of the register and correspondingly rotate one or the other number-drum according to the position of the clutch-member. These ten magnets are separately energizable by circuit-controlling means arranged at the sending-station, thereby to move the armature and rotate one or the other numberdrum according to which drum is connected with its driving-shaft.

Instead of employing a separate circuitwire for each magnet in addition to a common return-wire for the purpose of separately energizing said magnets I propose to divide the magnets into two groups of five each, as for instance, to include magnets to 4 in one group and magnets 5 to 9 in the other group, (see Fig. 36) and to employ two

common return wires

120 and 141 and to associate therewith circuit-controlling means '65 by which said groups are separately connected with said common return-

wires

120 and 141, which enables the employment ofbut five circuit-wires'as 121 in addition. to said two common return-wires, said five circuitwires each being arranged for connection with two of the ma nets of each group, and circuit-controlling means are provided at the sending-station for controlling the connections of said common return-wires with any of said five circuit-wires, which circuit-controlling means is in addition to the circuitcontrolling means for said five circuit-wires. The circuit-controlling means for the two groups of magnets, which are associated with the magnets, are arranged to be operated by means controlled by the magnets, and, as here shown, at the heel-end of each magnet (see Fig. 33) is an auxiliary-armature 44, which is pivoted at 46, and movable toward and from the corresponding end of 85 the core of the magnet, but normally held retracted by a spring 50, connected to a ring 50 attached by studs 50 to the plate 22, said end of the core being enlarged to enlarge the field by arranging an iron nut 47 thereon, which latter also serves to hold the parts of the magnet assembled, and in engagement with its supporting-plate. Each auxiliary-armature 44 has a tail-piece 48, which extends inward radially toward the 95 motor-shaft 20, and the tail-pieces 48 of the auxiliary armatures of one group of magnets coiiperate with beveled-teeth 52, on a carrier 54, see Figs. 38 and 40, which for convenience is loosely mounted on the motorshaft 20, in a recessed portion of the plate 22, and the tail-pieces 48 of the auxiliary armatures of the other group cooperate with similar beveled-teeth 56, on a carrier 58, see Figs. 38 and 41, also for convenience loosely mounted on said shaft 20, in the recessed portion of said plate 22. The

teeth

52 and 56 are formed respectively as sectors, and said sectors are arranged on their car-. riers and relative to each other, so that their 110 teeth form a circular series, and the beveled faces of the teeth extend diagonally across the faces of the carriers. The movement of any auxiliary-armature 44 into attracted position causes its tail-piece 48, to engage 115 the beveled side of one of the

teeth

52 or 56, and thus to im art a slight rotary motion to the

carrier

54, or 58, the carrier subsequently returning to normal position upon retraction of the auxiliary armature and a 12( correspondin movement of its tail-piece.

The carrier 54 has a contact-strip 60 arranged radially' on a block 61 of insulating material, which is of suificient length to engage five contact-

fingers

62, 62, 62", 62, 62 12! which are arranged in parallel relation and mounted on a block 63 of insulating material attached to the end wall 22, and each of said fingers is connected by a conductor 64, to a stationary conducting-strip 65 attached to 13 a block 66 of'insulating material, arranged on the end-wall 22, and each of said strips 65 is connected by a conductor 67, with'one of the magnet-

coils

5, 6, 7, 8, 9. Thus it will be observed that the contact-carrier 54, controlsthe circuits to all of the electro-magn'ets in the lower .half of the series. A spring 69 is connected atone end to the carrier- 54, its other end being connected to an ear on the plate 22, and tends normally to hold the contact-strip 60 in engagement with the fingers and to return said strip to such engaging-position u on retraction of the auxiliary-armature. e carrier 58 has a contactstrip 70 arranged radially on a block 71. of insulatin' material, which is of suificient length to enga five contact-

fingers

72, 72, 72 72, 72, which are arranged in parallel relation and mounted on a block 74 of in sulating material, attached to the plate 22, and each of said fingers is connected by a conductor 76, to a stationarv conductingstrip 75, attached to a block 77 of insulating material, arranged on the end-roll 22,

and each of said strips 7 5 is connected by a conductor 78, with one of the

magnetcoils

0, 1, 2, 3, 4. Thus it will be observed that the contact-carrier 58 controls the circuits of all of the electro-mao'nets in the upper half of the series. A spring 79 is connected at end of the carrier 58, and its other 'end-isconnected to an ear 80, which projects inwardlv from the late 22. This spring tends normally to hold thecontact-strip 70, in engagement with the fingers 72, and to re turn said strip to said enga ing-position upon retraction of the auXiliary-armatures. -For the purpose of locking the main- 1 armature 36, when it arrives at a predeter- 40 mined position and to hold it in such position until again moved. a disk 82 is secured to the shaft'20 which has notches 84 in its periphery, equi-distantly dis osed, and corresponding in number to the number of electro-magnets, and a pawl 88 which is arranged to en M of said notches. Said pawl 88 is pivoted at 90 and is engaged by a leaf-spring 91, which tends to hold its tooth'86 in enga ement with the notches 84,

and said pawl has a cam 92, adapted to be engaged by a pin 93, which projects from the carrier 54, and by a pin 94, which projects from the carrier58. Either of said pins operates to raise the pawl 88. and with-.

draw its tooth 86, from the notch 84, in which it has been engaged, when the carrier bearing it is given a slight rotary motion by a tail-piece 48,- therebv unlocking the shaft 20, so that the armature 36 may be rotated under the influence of any of the electro-magnets.

When a tail-piece 48, is swung outwardly, by attraction of an auxiliary-armature, and engages the teeth 52 or- 56, according to which magnet is energized, and slightly rosaid arresting

pawls

95 and 96.

ported on a plate 99 connected with the member 82, and are yieldingly held against a stop 97 by a spring 98, which is connected to both of said pawls. When "these pawls approach the tail-piece of the auxiliaryarmature of an energized magnet the first pawl which encounters the tail-piece is swung outward to allow said tail-piece to enter between the two pawls and to engage the second pawl, thereby to suddenly arrest said" member 82 and shaft 20 against rota-' tion. When the magnet is deenergized and its auxiliary-armature retracts, its tail-piece resumes its normal position and disengages Terminal plates are arranged on the outside of the casing 24, see Figs. 36 and37, to which the circuit-wires from the sending station are connected, and, as here shown 100, and 101, represent two end terminal plates of the two sets of magnets, which are mounted respectively on

blocks

108, 117, of insulation attached respectively to the two halves of the

casing

24, and 102, 103, 104, 105and 106 other terminal plates attached to the' block 108, which are connected respectively to other

terminal plates

112, 113, 114,115, 116, attached to the block 117 see Fig. 42.

As here illustrated (see Fig. 36 the terminal-plate 100, is connected by a wire 120 to one side of magnet 0, and the other side of said magnet is connected. by a wire 121 to the terminal102. One side of the magnets 0 to 4 are connected by

wires

122, 123, 124, 125 and 126 to the contact-

fingers

72, 72 72", 72 and 72 respectively, and one side of ma ets 5 to 9 are connected by

wires

127, 128, 129, 130, 131, to contact-

fingers

62, 62, 62 62 and 62, respectively. The other side of said magnets 5 to 9 areconnected by

wires

132, 133, 134, 135 and 136 to magnets 0 to 4, respectively, and the magnets 1* to 4 and 9 are connected

by'wires

137, 138,

139, 140 and 141 to the

terminals

103, 104,

group of mechanism 1 the terminal-

plates

100 and 104, by means of any suitable circuit-closing device-connected with a source of current. The current will flow from the terminal 100, through

wires

120, 122, finger 72, barv70, finger 72*,

wire 124, magnet 2, wire 138 to terminal ter engaging the teeth 52 and rotating the carrier 54, slightly to cause the pin 93 to engage the locking-pawl cam 92, and move the locking-tooth 86 to disengage .the disk 82. The shaft 20,.is now unlocked, and the main-armature 36 moves rotarily to bring its thickest portion into the field of magnet 2. In the meantime, as soon as the tail-piece has effected the unlocking of the sha t 20 .and the latter rotated, the former enters the gap between the two arresting-pawls- 95, 96, and arrests said shaft; also the rotary motion imparted to the carrier 54 causes the contact-bar 60 to disengage the contact-

fingers

62, 62, 62*, 62, 62 to break the circuit through the lower set of magnets to prevent energization of any of the magnets of said set. When the magnet 2 is deenergized the carrier 54 is returned by the spring 69 and the strip 60 again engages the

gers

62, 62 62*, 62, 62 and the disk 82 and shaft 20, together with the main armature 36 remain locked until another magnet is energized, whereupon its auxiliary-armature operates as above described. In case the shaft 20 was locked by a previous operation of magnet 3, and the thickest part of. the armature 36 is in the field of said magnet 3 at the time magnet 2 was energized, it will be observed that the shaft 20 will be rotated backward, such being the shortest rotary movement, to bring the thickest part of the armature into the field of magnet 2; or in case the shaft 20 was locked by a previous operation of magnet 1, at the time magnet 2 was energized, then the shaft 20'will be rotated forward.

In this diagram the magnet coils 0 to 4 of one set are electrically connected by wires 132 to 136 to the magnet coils 5 to 9 of the other set, instead of the terminal plates 102 to 106 directly engaging the terminal-plates 112 to 116, as represented in Fig. 42.- By this arrangement of circuits it will be ob-' served that the terminal-plate 100 and wire 120 leading from it are common to all of the magnet-coils 0 to 4 of one set, as said wire 120 leads to the coil 0, and the wire 78 leads from said coil to the set of contact-fingers 72 to. 7 2 which are normally closed by the contactstrip and that the terminalplate 101 and the wire 141 leading from it are common to all of the magnet-coils 5 to 9 of the other set, as said wire 141 leads to the coil 9, and a wire 131 leads from said coil to the set of contact-

fingers

62 and 62, which are normally closed by the conducting-strip 60 and that separate wires also lead mmsso contact fingers 72 to.'72 and that separate wires also lead from said'magnet-coils 5 to 9 to the other set of contact-fingers 62 to 62 The

common Wires

120 and 141 are hown in diagram as leading to the magnetcolls 0 to 9 for convenience'instead of eXtending directly to the conducting-

strips

70 and 60, respectively. I

At the sending-station is arranged the circuit-controlling means for the magnets 0 to 9 of the motor, whereby the number-' drums of the register are rotarily moved into different position, said circuit-controlling means having associated therewith graduated scales by which their positions are indicated to predetermine the operation of the motor and the corresponding operation of the register associated therewith. The instrument involving this means is represented in Figs. 1 to 20. I The component parts of this instrument are mounted on a base 400, and inclosed in a 'case 401. The range-numbers are arranged in two

rows

402, 403, see Fig. 1 which correspond to the numbers on the two number-drums and in addition thereto to the numbers on two targets, one for the fifties and the other for the tens of thousands. All of these numbers" are arranged on a plate beneath an opening in the case. Adjacent each row a slot is formed in which slot pointers 404, %05 are movable to point to the various num ers.

The row 402, here termed the hundreds scale consists of the numbers 0 to 950, in increments of fifty, and the row 403 here termed the thousands scale consists of the numbers 0 to 19 inclusive. The pointer 404 and the pointer 405 is designed to be similarly operated by a hand-actuator 407, here represented as located at the left hand end of the instrument. The pointer 404 is secured to a block 408, internally screwthreaded and arranged for movement on and by a worm-shaft 409, and said shaftis mounted for rotation in suitable bearings and has secured to it at one end a pinion 410, see Fig. 5, which is engaged and driven by a train of gearing engaging a beveled. pinion 411, which is secured to a shaft bearing a toothed gear 412, which is engaged and driven by another train of gearing engaging a toothed gear-413, (see Fig. 6), which is secured to the lower end of an upright sleeve 414, having suitable bearings,

the upper end of said sleeve being secured to an upright sleeve 415, having suitable bearings, and said sleeve 415 being rigidly connected with the hand-piece 406. By swinging said hand-piece 406 in an arc of a circle said sleeves and trains of gearing are moved and the wormshaft is rotated,

cated at the right hand of the instrument,

The trains of gearing. are especially provided for the purpose of enabling the handpiece to be moved through a short are and the worm-shaft tomake a complete rotation for each number indicated on the scale, thus to move the pointer the entire length of the slot to point to all of the numbers in the row. Said block 408 carries the movable.

tact-member 420 common to all of the contact-members 421 (see Fig. 11), and there being ten of said contact-members 421, which correspond to the ten magnets of the motor; and the other pair of contact-members, as 419, being arranged for engagement with the stationary contact-members 424. 425, 425 also secured to said block 423, there being one contact-member 424 common to the contact-members 425 and425,

and said contact-

members

425, and 425 correspond to the two groups of magnets of the motor. As the block 408 is moved along by the hand-piece, the contact-members borne by it are correspondingly moved over the stationary contact-members, and the pair of contact-members 418 and their cooperating stationary contact-

members

420 and 421 are arranged for connection with the separate magnets 0 to 9 of the motor, when the motor is arranged in connection with the hundreds number-drum, and the pair of contactmembers 419' and their cotiperating

stationary contact members

424, 425 and 425*, are arranged for connection with two common return-wires which are connected with the group-selecting circuit-controller at the motor, by which selection of oneor the other group of magnets O to 4 and 5 to 9 is accomplished.

Referring to Fig. 11, 1t Wlll be observed that the stationary contact-member 425, is

coextensive with the first group of five stationary contact-members 421, and that the stationary contact-member 425* is coextensive with the second group of five stationary contact-members 421, and by this arrangement while the movable contactmember 418 is in engagement with any one of the. five stationary contact-members of the first group the movable contact-member 419 is in engagement with the stationary contact-member 425, and while the movable contact-member 418 is in engagement with any one of the five stationary contact members of the second group, the movable contact-member 419 is in engagement with the stationary contact-member 425, thus to make electrical connections with-the separate groups of magnets of the motor and the separate magnets of said groups. The

pointer 405 is secured to a block 426, which is internally screw-threaded and arranged for movement on and by a worm-shaft 427, and said shaft is mounted for rotation in suitable bearings and has secured to it at one'end a pinion 428, see Fig. 4, which is engaged and driven by a train of gearing engaging a bevel-pinion 429, which is secured to a shaft bearin a toothed-gear 430, which 1s engaged and rive'n by another train of gearing engagmg a t0othed-gear'431, which 1s secured to the lower end of a sleeve 432,

having suitable bearings, the upper end of said sleeve being secured to a sleeve 433,

having suitable bearings, and said sleeve 433 bein piece '40 407, in the arc of a c rcle, said sleeves and trams of gearing are moved and the wormrigidly connected with the hand- By swinging said hand-piece shaft is rotated in a manner similar to the corresponding parts connected with the hand-plece 406, Said block 426 carries the movable contact members of the other group of circuit-controlling means for the motor,

and as here shown, has attached to it a block 434 of insulation to which two pairs of contact-members, as 435,436, are attached, one of said pairs of contact-members, as 435, being arranged for engage-' ment with stationary contact-

members

437, 438, secured to the other side of said block 423 of insulation, there being one contactmember 438, common to all the contact-- members 437, and there being, as here shown, twenty contact-members 438, the first ten corresponding to the ten magnets of the motor and the second ten being a duplication of the first ten, and the other pair of contact-members, as 436 being arranged for engagement with stationary contact-

members

439, 440, 440*, also secured to said block 423, there being one contact-member 439, common to all the contact-

members

440 and 440 and there being here shown two groups of contact-

members

440, 440*,

the first group corresponding to the two groups of magnets of the motor, and the second group being a duplication of the first group, so that as the block 426 is moved along by the hand-piece 407, the contactmembers borne by it are correspondingly moved over the stationary contact-members.

tact-

members

439, 440 and 440, are arranged for connection withthe two common return-wires which are connected wlth the group-selecting circuit-controller at the motor by which the selection of one or the other group is effected. Referr ng to Fig; 12 it will be observed that the contact-

mem bers

440, 440, are coextensive with the first and third. group of five contact-members 437, said contact-

members

440, 440, being connected with the common return-wire of one group of magnets of the motor, and the first and third groups of contact-members 437 being connected with the five magnets of said group; and that the contact-members 440", 440, are coextensive with the second and fourth group of five contact-members 437, said contact-

members

440, 440, being connected with the common return-wire of the other group of magnets of the motor, and the second and fourth group of contactmembers 437 being connectedwith the five magnets of said group, so that While the movable contact-member 435, is in engagement with any contact-members of the first and third groups the movable contact-memher 436, is in engagement with the

contactmembers

440, 440, corresponding to said first and third groups of contact-members;

and while the movable contact-member 435 is in engagement with the contact-members of the second and fourth groups, the movable contact-member 436 is in engagement with the contact-members 440*, 440, corresponding to said second and fourth groups of contact-members 437, thus to make electric connections with the separate group of magnets of the motor and the separate magnets of said groups.

It will be observed that on the thousands scale are numbers 0 to 9 representing the thousands, and also numbers 10 to 19 representing the tens of thousands, and the thousands are indicated on the thousands number-drum with the target 204, set at 0, and the tens of thousands are indicated on the same drum with the target 204 set at 1, and the two groups of circuit-controllingmeans here shown in duplicate, see Fig. '12, are employed for controlling the motor While the thousands number-drum is in operative connection therewith, the first group being employed to operate the motor and consequently the number-drum to indicate the thousands and the second group, which is a duplicate of the first group,'being employed to operate the motor and consequently the same number-drum to indicate the tens of thousands.

It will be remembered that the clutch for the number-drums is normally in position either connecting or to connect the hundreds number-drum with its drivingshaft, and hence with the motor, and that said clutch must be shifted to connect the thousands number-drum with said driving-shaft and motor, and that such shiftln of the clutch is accomplished by means 0 the relay 230, which is assoc'iated with the before the thousands actuator is rotated, and, as here shown, see Fig. 4, a 011'01113 controller is provided for the-circuit of said relay 230, represented by a pair of stationary contact-

members

445, 446, and a movable contact-member 447. The stationary contact-

members

445, 446 are arranged on a block 448, of insulation, and the movable contact-member 447 is arranged on a block shift the clutch. Also said" 449 of insulation, and said block 449, is connected with means by which it is moved up and down by means associated with the thousands hand-actuator 407. It so happens that said block 449 carries other contact-members, which will be referred to, and also said block and the means for moving it are associated with the thousands actuator 407, in the same manner as a. corresponding block bearing contact-members is associated With the hundreds hand-actuator 406, and reference is therefore now made to Fig. 6, wherein the hundreds actuator is shown. The moving-means for the block involves a sleeve 450, to which said block is attached, which sleeve is loosely mounted on a stem 451, and rests on a collar 452 on said stem, and said stem is movable axially for a short distance and extends up through the sleeve 414 and terminates in a chamber in the hand-piece of the actuator, wherein means are provided for lifting it, thereby to lift the blockv 449 against the stress of a return-spring 453. The means here shown for moving said block consists of a lever 455, arranged within the handpiece and pivotally supported, and engaging, at one end, the upper end-portion of said stem, its other end extending beneath a thumb-piece 456, by which said lever is depressed, and also another lever 457, pivotally supported within the hand-piece, one end of which engages the aforesaid lever and the other end extends beneath a fingerpiece 458, seated in the hand-piece, which when depressed acts to move it. By pressing inward either or both

pieces

456, 458, the stem will be lifted thereby raising the block and causing the contact-member 447,

' to engage the contact-

members

445 and 446,

ated by the hand-actuators shall be arranged v to operate on an open circuit, thereby to prevent arcing, and to accomplish this result another circuit-controller 1s arranged in a circuit-wire which is common to all the cirv on the armature-lever 464 of a relay 465 which is associated withthe sending instrument, said contact-members constituting the circuit-controller in said common circuitwire. The circuit of said relay 465 is controlled by both the thousands actuator and the hundreds actuator to close said common motor circuit.

In view of the fact that when operating the thousands actuator the clutch must be disengaged from the hundreds numberdrum and that the motor-circuit must not be closed by this common circuit-controller 460,

461, 463, until after such disengagement has been effected, it is herein designed to operate the circuit of the relay 465, by means associated with the clutch-mechanism, which it will be understood is controlled by the thousands actuator only through the relay 230,

and, herein, as seen in Fig. 22, the clutchlever 216 is arranged to engage a contactmember' 235, which latter, when depressedv engages a contact-member 236, thereby to closethe circuit of said relay 465, when the relay 230 is energized and its armature is attracted, as at such momentthe clutch-lever -is moved and the hundreds number-drum is disengaged, although said clutch-lever may be moved only into its middle position, preparatory to engaging the other drum. But when operating the hundreds actuator the clutch has disengaged the thousands number-drum upon denergization of said relay 230, and hence the circuit of the relay 465 may be directly controlled by a circuitcontroller which is associated with the hundreds actuator. Referring to Figs. 5, 5, 6 and 36, a pair of stationary contact-

members

466, 467 are arranged on'the stationary block 448 of the hundreds actuator, which contact-members are adapted to be engaged'by a contact-member 468, attached to the block vated position, so asvto prevent them from returning to normal, said locking-means holding the sleeves with the contact-

members

466, 467 borne by them in engagement with the stationary contact-members 468, thereby to maintain the circuit of said relay 465, closed at this point, although other functions are also subserved, as-will be hereafter aescribed. As here shown, in'Fig. 2 particu larly, said locking-means consists of a pair' of engaging-bars 470,471, slidably mounted for f engagement, respectively, with said sleeves, and said bars are arrangedin alinement and the1r inner or ad acent ends are inclined and engage a pair of rolls arranged on a support 472, which support is loosely connected with an arm attached to the rotating armature carrying shaft of the .relay 465, and a sprlng 473 is connect ed at its ends with the rolls. Upon energization of said relay 465, responsive to the circuit-controller operated by the clutch-lever 216, which is controlled by the thousands actuator, the bar 470 will bemoved longitudinally into engagement'with the sleeve, of thethousands actuator, and upon energization of said relay 465, responsive to the circuit-c0ntroller associated directly with the hundreds actuator, the bar 471 will be moved longitudinally into engagement with the sleeve on the hundredsactuator.

These locking-bars are subsequently operated to disengage the sleeves, as will be hereinafter described. It will be noted that energization of the relay 465 also indicates the fact that the clutch has been shifted.

Upon closure of the common motor-circuit .by either the thousands or the hundreds actuator thus described, involving the operation of the relay 465, the circuit of any magnet of the motor which is closed by either hand-actuator at such moment will be closed and the corresponding magnet will be energized. When said motor-magnet is thus energized the auxiliary-armature 44 of said magnet is attracted, unlocking the armature-shaft of the motor and permitting rotary movement thereof to bring the armature into correct position with respect thereto, to admit of rengagement of the clutch which has been previously moved. The said auxiliary armature 44 is also arranged to control the circuit of a relay 480, and, as here shown, said circuit is connected by wires 152, 153, see Figs. 32 and 36, with a pair of contact-members 152, 153, ar-

ranged on the outside ofthe end wall 22 of the motor case, and said contact-members bear upon a pair of contact rings 154, 155, which are insulated from but supported by the motor-shaft 20,. see Fig. 33, and said contact-rings are, respectively, connected by wires with a pair of contact-members 156,

157, which are arranged on an insulating disk borne by the shaft. The said contactmembers 156, 157 extend upward and back of the

pawls

95, 96, see Fig. 35, and their extremities are normally disengaged but are adapted to be engaged to close the circuit; As here shown they are associated with the pawls and are movable with said pawls rov tarily by the motor-shaft, and are brought into correct position with respect to theenergized magnet by the motor-shaft, 1n whlch "position the pawls engage the ta l-piece of the-armature. An insulating arranged on the member 157, which extends '15 inward toward and into engagement with the pawl and also extends outward toward 7' and into engagement with the contact-member 156, see Figs; 33 and 35, so that SaId OOI I- tact member is movable by either pawl, and

. will be moved when the tail-piece engages and moves either pawl. Such movement causes the contact-member 157 to move rearwardly and also causes a corresponding movement of a contact-member 156, so that both members are moved but their relation to each other remains unchanged. Said contactmember 156 has arranged on it an insulating pin 156 which extends toward the tallpiece and terminates at the tail-piece when the latter is in its abnormal position, withthe" armature attracted. This being the 7 case, it will be observed that when the contact-member 157 is permitted to return by either pawl resuming its normal position,

said contact-member 156 will be held in its It is, however, important that the relayshall not be energized by said contact-members associated with the motor unless the clutch is in engagement with one or the other number-drum, and to insure such position of the clutch, a U-shaped contact-member is associated with two contact-members 682 and 683 and the clutch-lever is extended into a position between the

arms

680, 681, of said U-shaped contact-member for e11- gagement therewith and when said clutchlever is in one' or its other extreme position with the clutch in engagement with oneor the other number-drum, one or the other of said arms will be moved into engagement with one or the other contact-member and to thereby close the circuit of said relay 480, at such point. This circuit controller operated by the clutch-lever is arranged in series relation with the aforesaid circuit-controller pin 157 2 is imaeeo which is associated with the motor, therefore, unless the circuit-controller which is operated by the clutch-lever is closed thereby, the operation of the other circuit-Controller will have no effect. When the clutchlever is in a middle position, both

arms

680, 681, of the .U-shaped contact-member are moved away from their corresponding contact-members 682, 683, so that the circuit is open at such points and is only closed when the clutch-lever is in one or its other extreme position. Also in series relation in said circuit of the relay 480, is another circuitcontroller, which is associated with. the targets, will be hereinafter described, and not 36 until all of the circuit-controllers which are arranged in series relation in the circuit of said relay 480 are closed will said relay be energized. Referring again to Fig. 36, the circuit wire. 153 extends to the terminal plate 678, and wire 678' connects said plate with the U-shaped contact member 680', 681 including one or the other arm thereof and one or the

other contact member

882 or 683," and a circuit wire 776 extends from said

contact member

882 and 683 to the

circuit controller

275, 276, and a circuit'wire ex: tends from said circuit controller to the terminal 633 and circuit wire 634 connects said terminal plate with the negative side of the battery. Said relay 480 is employed to control the circuit of the relay 465, for the purpose of deenergizing said relay 465,

which has been previously energized, in order to open the common motor-circuit, so that the hand-actuators may operate to move the motor circuit-controller along with the motor-circuit open, thus to avoid arcing during such movement, after which the motor-circuitis closed. This result is accomplished by providing relay-

contacts

481, 482, arranged in the circuit of the relay 465, and engaged by a contact-roll 483, arranged on the rotary moving armature 484, of said relay 480 as seen in Fig, 10. Said relaycontacts 481, 482, are normally engaged by the contact-roll 483, when the relay 480 is deenergized, thus closing the circuit of the relay 465 at such point and at such time, but upon energization of said relay 480 by the closure of its circuit by all said circuit-controllers, said relay-contacts are moved to open the. circuit of said relay 465 and permit deenergization of the relay 465 and the opening of the motor circuit. Another circuit-controller is arranged in the circuit of said relay 480, which consists of a pair of contact-

members

485, 486, whichare associated with the relay itself and arranged forengagement with the'contact-roll 483 in such manner that when said relay is energized and its armature attracted, said contact-roll will be moved into engagement with said contact-

members

485, 486, and thereby close the relay-circuit. This circuit-conhas been opened and the motor-magnet has,

been denergized and the auxiliary-armatureof the motor-magnet has returned. When first completing the motor-circuit as aforesaid, it is necessary to maintam closure thereof for a short period of time before operating the actuators, thereby to insure the shifting of the clutch from one to the other number-drum, and its reengagement therewith, and to provide this interval of time, means are employed for temporarily arresting further upward movement of the sleeves 450, which are associated with the hand-actuators. As here shown, a pair of

bars

475, 476, are arranged for engagement with said sleeves, said bars being arranged in alinement and their inner or ad'acent ends connected together by a sprin 47 and said inner ends of the bars are inc ined, and' said inclined ends engage rolls borne by a support 478, which is loosely connected with an arm 479 attached to the shaftof' the rotary moving armature of the relay 480. Said bars are normally in their outermost positions and designed to be drawn inward toward each other to disengage the sleeves. In this instance both bars are operated simultaneously upon energization of the relay 480, to disengage the sleeves, and thus permit further upward movement of the sleeves.

To insure the circuit being normally open at the sending-instrument two circuit-break,

ers are associated with each hand-actuator, one for each bus-bar circuit, which, when the sleeves 450 thereof are in their lowermost positions are arranged to break the circuits, but which, when said sleeves are lifted, act to close the circuits at such points. As here shown, see Fig. 4, the circuit-breakers associated with the thousands actuator consist of a pair of contact-

members

490, 491, arranged for engagement with a contact-member 492, arranged in one of the bus-bar circuits, and the contact-

members

499, 500 arranged for engagement with a contact-member 497, arranged in the other bus-bar circuit. As here shown, see Figs. 5 and 5 the circuit-breakers associated with the hundreds actuator consist of a pair of

contactmembers

493, 494, arranged for engagement with the contact-member 495, and arranged in one of the bus-bar circuits, and contactmembers 467 and 501, for engagement with the contact-member 468, and arranged in the other bus-bar circuit. Heretofore there are described contact-

members

485, 486 and 483, which are associated with the relay 480, and which operate to close the circuit of said relay and thereby maintain said relay energized, but subsequently the circuit of said relay must be opened, and to accomplish this result a contact-member 496 is associated upward movement of controllers thus described are closed andupward movement with the sleeve of the thousands actuator and arranged. for engagement with the contact-member 497, and the contact-member 498 is associated with the sleeve of the hundreds actuator and arranged for engagement with the contact-member 468, and upon said sleeves the circuitupon downward movement thereof are opened, thus to open the circuit of said relay .480, upon the downward movement of said sleeves;

To arrest the downward movement of the hand-actuators after they have been moved to operate the circuit-controlling device for the motor, so as to afi'ord ample time for the relay 480 to deenergize and the relay 465 to energize, a mechanical locking-device, here shown as 'a pawl, is provided for each actuator. Referring to Figs. 2, 14 and 15,503 represents the pawl which is associated with the thousands actuator, which is pressed by a spring 504 into engagement with the sleeve of said actuator and when said sleeve is lifted said pawl moves into engaging position beneath a projection 505 on the sleeve and remains in such position until positively withdrawn. The withdrawal of the pawl is accomplished by an outward sliding movement of the. engaging-bar 470, which, it will be remembered, is moved outward upon energization of the relay 465. 506 represents the pawl which is associated with the hundreds actuator, which is pressed by a spring 507, into engagement with the sleeve of said actuator, and when said sleeve is lifted said pawl moves into engaging position beneath the projection 508, on the sleeve and remains in such position until positively withdrawn. The withdrawal of the pawl is accomplished by an outward sliding movement of the engagingbar'471, which, it will be remembered, is moved outward upon a subsequent energization of the relay 465. To provide against of both hand-actuators at the same time a locking-device is arranged between the two actuators, which is moved by either to prevent movement of the other. Said locking-device, as here shown, see Fig. 2, consists of a long bar 510, having its endportion arranged for engagement respectively with projections sleeves of the actuators, and said end-portions and projections are formed with beveled engaging-faces.

Springs

513 and 514 are connected with said bar and extended in 511, 512, on the opposite directions which act as return
