The vsystem as a iuhole brief idea of the system kas a whole will first be very b rieiiy indicated,'after which the parts will be described in detail. The system comprises a register or key (Figs. 3 to 10), preliminary stalio means 13, 14, 32 for locking tions (Figs. 21 to 25), whichhave to be visited, .in'sequenca in` order to condition the key for sending a'signal at a transmitting station (Figs.

'v1 and 2).

Thefregister or key hasV an inner nose 11, an outer nose' 21 and a long lug 27 all, at times, movable relatively to each other forconditioning the key, and a plurality of characteristic together the lug 27 and the cylinder Y10 carrying the first nose. There are also means 43,44, 45 (Figs. 4 to 6) for locking the rst and second nose and lug together, and bumps 36 for unlocking them at one certain predetermined position' of rotation of the lug 27 relative to the irst nose 11. f.

Each station` of the series of preliminary-stations 1r to 9 (Figs. 18 and 19) has ribs 83 (Fig. 23) receiving the lug 27 and characteristic stop means 90 engage'able with the noses for preventing the complete insertion of the key when the key is not conditioned to be receivedby the

notches

92, 93 of that stop means, Vand means such as yieldably protruded balls 86, for unlocking the means 13, 1432 of the key when conditioned for the station, saidrribs 83 serving, when the key and cylinder 10 are operated, to move the lug 27 relative to the innernose ll'to condition the key for the nekt succeeding station.

Each station conditions the key for the nekt station only, so that it becomes necessary to make a complete round before the same transmitter station can be operated again.Y

Now the various parts of the system will be described in detail.

The register or key,

The key or register for our watchmans compulsorytour system comprises a main hollow cylinder 10 (Fig. 4) having at its forward end, an inner or lower digit actuating nose 11.V Said cyl- 'inder has therein a number ofl perforation locations arranged in longitudinal rows equal angles apart and in annular series'equal distances apart, perforations 13, 14 being provided at certain of said locations and omitted in'others, 'so that each longitudinal row 13, 14 containsa different combination of perforation's. A handle 15 (Fig. 3) is provided with aplug -16 (Fig. 4) secured fastby a protected pin 17 inY theV outer end of the cylinder.

The outer or higher digit nose An annular enlargement 19 forming a shoulder at the inner end of the cylinder is'formedto provide the arcuate inner nose l1 extending about 60 around and projecting slightly longitudinally from the inner end. An outer or higher digit outer nose sleeve 20 rotatably receivedon said cylinder and enlargement 19 is provided with outer nose 21 projecting about the same distance as the inner nose, and is provided at the inner edge with an innerY shoulder engaging against said shoulder of the enlargement 19 to hold the sleeve inplace.

A shell 25 held fast on Vthe outer endportion of the cylinder by the pin 17 has its inner Vend part spaced from the cylinder for kforming adeep annular space receiving the end portion 26 of Ya

long lug member

26, 27, 28;

The long Zag and tumbZers The

long lug member

26, 27, 28 comprises a long cylindrical portion 26, 23 rotatably received on the cylinder between said Vsleeve and shell and in said space, and a long lug 27 extending vfrom the shell to near said sleeve 20, said lug being provided with radial bores 29 having open reduced innerL ends 30 registerable with said perforation Alocations and perforations 13," 144 when present.V

Tumblers or plunger pins 32, 33 in said bores have reduced ends 32 adapted to protrude'into, and lock in, respective registering perforations 13, 14Mof the main cylinder, and heads 33 er1'- gageable with the reduced ends 30 `of the bores to limitV protruding movement, the tumblers being yieldably protruded by springs 34 compressed against said heads and the closed ,ends'of the bores.

. 'The'outer-nose lock Y Adjacent ends of said sleeve 20 and cylindrical portion 28 are provided with interior annular grooves 35'receivm'g bumps 36 of the main cylinder, said ends being reduced in diameter' to form an router bearing groove to receive a

shortV lug member

38, 39 comprising a cylindrical portion 88 rotatably received in said outer groove, and la short lug 39 normally alined with the long -lug 27 andY at times rotatable relative thereto and provided with radial bores 4()v having open inner ends.

Springs 42 in the bores press plunger pins 43 respectively into one of the perforations 44 (Fig. 5) of the outer nose sleeve and a perforation 45 (Fig. 6) of the long lug member. Said bumps 36 are positioned to engage said plunger pins 43 after each complete rotation of the cylinder relative to the long lug, thereby releasing the outer or higher digit nose, so that it may be moved an increment on each revolution of the inner nose, thus multiplying the number of relative positions of the two noses for conditioning the key for a large number of stations.

Automatic key-disabler and tell-tale The rear end of said cylindrical portion 26 (Fig. 9) of the long lug is provided with an annular series of periorations 48 successively registerable with a perforation of the main cylinder 10, in which may engage a locking pin 50 movable in a transverse bore 51 in the plug 16. A spring 52 compressed between a collar 53 on the pin and the cylinder l0 serves to retract the pin from the perforations 48 of the long lug member to permit relative rotation of the lug member and cylinder l0.

A longitudinal bore 55 in said plug 16 near one side thereof across the inner end of the transverse bore 51 terminates at its rear end in a laterally open enlarged recess 56 laterally closed by the main cylinder. A spring 57 compressed in said recess tends to slightly project an actuating pin 58 (Fig. 8) longitudinally slidable in said longitudinal bore and provided with an inner head 59 to limitits projecting movement, and anormal diameter rear lportion 60 normally engaging the locking pin to hold the latter in locking position, as in Fig. 4.

The intermediate part of said actuating pin is tapered in opposite directions to an intermediate reduced portion 62, and adapted when the actuating pin is forced into the bore, by normal engagement with the core 85 (Fig. 24) or 108 (Fig. 1) of a station, to engage the inner end of the locking pin to allow the latter to withdraw from the lug member to permit relative rotation of the lug member 26, 27 and cylinder :0, only when the key is all the way in the staion.

The actuating pin has also a shallow tell-tale groove 63 therearound forming abrupt shoulders, between said reduced portion 62 and the outer end 65 of the pin, whereby if the actuating pin is pushed back too far, as by a person attempting to manipulate the tumblers, the locking pin 50 is trapped between said shoulders and the locking pin is locked in projected locking position.

Station indicia An arrow (not shown) on the outer face 65 (Fig. 3) of the long lug 27, cooperates with a series of station indicia such as the letter T on the handle (Fig. 3) and Arabic numerals 67, serving to indicate stations, arranged around the key shell 25 near the long lug, to indicate the position of the long lug relative to the shell and inner i nose, and to indicate the stations which the inner nose 11 is positioned to fit. A series oi tour section indicia, such as letters 68 arranged around the outer nose sleeve 20, and an index pointer 69 on the short lug member and associated with said series indicate the position oi the outer nose relative to the lugs, thereby to indicate the tour section ot series of stations which the outer nose is positioned to fit.

Preliminary stations Each regular preliminary station 75 (Figs. 21 to 25) may comprise a base 76 adapted to be secured to a wall or other support and carrying an approximately cylindrical outwardly tapering housing 77 having an outer iiange 78 secured to the base, and an outer end wall 79 (Fig. 24) provided with a keyhole 80, 8l comprising a circular part 80 adapted to receive the cylindrical portions 20, 26 of the lug members and a radial part 8l adapted to aflord a passage way for the

lugs

27, 39. Interior parallel ribs 83 on the side wall of the housing form' a continuation of the radial part 8i as a passage way for the

lugs

27, 39 and serve to hold the lugs against rotation.

A guide core 85 secured fast on said base axially of the base and housing is provided with radial bores (as in said patent) disposed in a plane passing through the axis of the radial part of the keyhole. Said bores have outwardly opening reduced outer ends with which said row oi periorations 13, 14 are registerable when the key is inserted through the key hole the proper distance on the core; and springs compressed in each bore serve to yieldably protrude plunger balls 86 pressed by said springs against, and slightly projected from, the reduced ends, thereby to engage and push back projecting tumbler pins 32, 33 of the key, thereby to unlock the cylinder l0 from the long lug 27.

Said casing 79 is provided with

interior shoulders

87, 88 facing and near said base on which are secured a back stop plate 90 provided with a central opening 91 receiving said core, and with

arcuate notches

92, 93 beveled at the end as at 94 adapted to receive said noses l1 and 21 respectively, the notch 92 being long enough to allow a lost-motion movement equal to the angle which the nose is to be advanced, while the outer notch 93 snugly receives the outer nose.

Operation at preliminary stations The line 97 of arrows of Fig. 18 'represents the complete journey of a watchman making a complete tour past the preliminary stations represented by numerals l to 9, the semimaster or skip stations SM and transmitting stations A to E. 'Ihe stations succeeding station E and ending with station A may be called tour section A, the succeeding stations terminating with station B are section B, and so on.

When the register is conditioned so that the arrow 69 is pointing at the letter A at 68, and the numeral 1 at 67 is opposite lug 27, the register is conditioned for and the noses ll and 2l are positioned to be received in the notches 92, 93 (Fig. 23) as positioned in station l of tour section A. Thus when the register is inserted in this station the pin 58 (Fig. 8) is pushed back, unlocking the parts, the

lugs

27, 39 will be held between the ribs 83, the noses 1l and 2l will be positioned to enter the

notches

92, 93, the inner nose engaging the bevel 94; and all of the plunger pins 32 which protruded into perforations at that setting of the register, will respectively engage with all of the balls 86 of such station, the balls 86 of that station and the periorations 13, 14 of that position of the register being characteristically identically arranged. In like manner the register positions and stations of the same indicia number are respectively identically arranged.

When the key is thus inserted the protruding The resistance of the upturned end 131 against the hook forces said front pin against said edge 144, forcing the stop plate against the stop pin 143, to hold the clockwork from unwinding until fully wound and until the V-shaped stop plate has forced the hook 134 from the winding lever, to permit the lever 130 to rise and the clockwork to operate.

'Ihe lower margin 146 of the guide block 136 is beveled to engage the guide pin 135 on `the upstroke to lift the guide pin to the front face of the block until the path thereof meets said edge 137 and the pin snaps against said edge. The pillar 148 (Fig. 11) stops the downward movement of the lever.

An inverted L lever 150, 151 (Fig. 1) having its lower part 150 secured fast on the winding shaft 132 of the clockwork, has its lateral member 151 normally disposed over an intermediate part of the path of the long lug 27.

Saidlateral member 151 moves forward of the lug 27 as the lug moves forward as the winding and actuating levers are lowered, thereby to remove itself from the cam tace 153 of a stop member 154 pivoted to the bracket 112, thereby to allow the shoulder 155 to drop into the path ofy the long lug 27, to prevent the removal of the key until after the signal is completed and said lateral: member 151 engages the cam face 153 to raise said shoulder 155 from the path of the lug, the later-al member 151 then holding the member 154 in raised position.

Register trapping sigmzl It isusually desired that the register remain locked in` the transmitting station during the time that the watchman is not on the tour, and that the central office be informed that the register is thus locked. This is accomplished as follows:

Thecode signalwheel 129v is toothed to give the same signaltwiceias at 129', 129, and after one set off teeth has actuated the signal contacts 160, the clockwork is automatically stopped. This is accomplished by the engagement of a stop arm 161. faston ther code signal wheel shaft, with a flat. spring 162 having an end 163 secured fast onthe side wall of the housing. The free end is normally disposed across the path of the end of the stop arm in position to stop the arm and clockwork, with the register locked therein, after oneof the two signals hasbcen sent.

A push button 165 (Fig. 2) on the front of the front wall has a stem 166 slidably passed through thewall, and resting on the flat spring, whereby pressure on the button pushes the spring from the stop arms and allows the second signal to be sent andthe register to be released.

The Wiring connected to the switch 160 may be as shown in said patent and need not be shown orv described here.

Higher digit nose stepping' disk The transmitting station is operated at the end ofthe tour section; after the bumps 36 (Fig. 4) of the register have made a complete revolution and are ready to engage the pins 43 to release the outer nose 21, to allow the latter to be moved an increment in the transmitting station to condition the registerv for use in the next succeeding tour section only, and to prevent use in the other and preceding sections.

Hereinwewill illustrate and describe a number ot. different forms of mechanism for bringing about this movement, one being shown in Figs.

11 to 17, other forms being shown in Figs. 20, 31 and 38 respectively.

First will be described the mechanism of Figs. 11 to 17. In this figure the movement of the outer nose is brought about by movement of a stepping disk 168 (Figs.`1 and 11 to 15) having a circular opening 169 (Fig. 14) received on said flange 123 (Fig. 11) and provided with an arcuate notch 170 (Fig. 11) adapted to receive the outer nose 21.

Said disk has therearound a series of frontwardly pointing pins 172 forming a pinion engaged by a stepping sector 173 (Fig. 11) pivotally mounted on a bracket 174 mounted on and offset from said back wall. The sector moves between said bracket and back wall on a pivot bolt 175 rotatableV in the bracket below an intermediate part of the actuating lever, said sector having peripheral teeth 176 engaged between said pins 172.

A radial finger 178 (Figs. l1, 16 and 17) is integral with the bolt 175, and a radial lever 179 is adjustably secured fast on said bolt by means of a pin 179 and carries a pin 180 pressed by a flat spring 181 into one of the holes 182 in the sector, whereby the finger is adjustable to be engaged by an actuating pin 183 (Fig. 11) mounted'cn an adjustable plate 184 adjustably secured onV the actuating lever 120, whereby when the inner nose 21 of the operated register causes the actuating lever 120 to move down, the actuating pin 183 moves the ringer 178 and rotates the sector and thereby the stepping disk an amount and a direction depending, as will be explained, upon the adjusted position of the finger 178 and the distance of the pin 184 from the pivot point of the sector and whether or not the pin passes between said bolt 175 and the core 108.

The apparatus as in Fig. 11 is for use with a tour circuit as in Fig. 18. If the transmitting .station corresponds to station D, the previous sations A, B, C will each have stepped the outer nose around one increment, in a clockwise direction, in the manner now to be described, and it will only be required that the station D step the outer nose one more increment in the same manner in a clockwise direction, as will now be described, to condition the outer nose for the station E.

This is accomplished by the disk 168 as in Fig. 14. The outer nose enters the notch 170, and it is desired that the nose .be advanced in clockwise direction one increment (one-tenth of a revolution) by the operation, to condition the outer nose for station E. To accomplish this the finger' 178, the pin 183 and the cam 186 must be disposed relative to the bolt 175 as in Fig. 11a. If the outer nose were to be moved counter clockwise, these parts would be placed to the right of the bolt 175, as in Fig. 11.

To adjust the device to advance the outer nose in a clockwise direction the sector 176 is removed and replaced with the cam 186 above the bolt 175, as in Fig. 11a; the pin 183 is adjusted just under the cam 186 slightly to the left and abovev the bolt 175, thus to move down (when the lever 120 moves down) at the left of the bolt 175; and the finger 178 is adjusted to incline toward the core to be quickly engaged and moved by the pin 183 and be moved from the path of the pin by the time the lever reaches the position 120g. The pin 183 and finger are so placed, that the sector 176 and stepping disk 168 will be moved, as will be explained, an amount just sufiicient to move the outer nose one increment.

With the parts thus adjusted, the forward rotation of the register cylinder causes the bumps 36 (Fig. 4) to engage with, and unlock, the pins 43, and also carries down the lever 120 as above explained, whereupon the actuating pin 183 strikes the linger 178 and moves the iinger a .short distance out of the path of the pin, thus moving the sector a small amount, and the stepping disk and nose 21 forwardly one increment in which it is locked by a pin 43 in a perforation 44 (Fig. 5) of the outer nose sleeve, the short lug 39 remaining stationary between the stop 185 (Fig. 2). Y

On the return stroke of the lever 120, the long lug returns to alinement with the short lug and a pin-43 snaps into the single perforation 45 (Fig. 6). i At the same time the inner nose, whichV is received without lost motion in the notch 124 was advanced relative to the long lug on the forward stroke, now moves 27 strikes the shoulder 113 holding the now advanced inner nose notch 124 and lever 120 against complete return to original position, the lever being thus left in the position of the dotted line er. At the same time, the pin 183 which left the linger 178 moves back to the`position, where' it left the nger. The register may now be withdrawn, allowing the inner notches 124 and actuating lever 121 to be restored completely bythe spring 126. This causes the pin 183 to engage the double cam 186 and move the sector 173 and outer notch 170 to original position.

y'Skip station operation By adjusting the Vnger 178 Vand pin near to the position of the full lines of Fig.-11, the stepping disk may be backwardly rotated two or more increments, to advance the outer nose from the position of station E lto position for station A. Y'Ifnis is` necessary when, as in Fig. 18, less than ten tour sections are used. If only one section is omitted, the pin -183 and nger are adjusted tostep the disk 168 two increments; if two sections are omitted, the pin and nger are adjusted to step the vdisk 168 three increments.

If the register provides for ten tour sections and more than 4 or 5 are omitted, it is desirable to step the disk 168 backward rather than forward, in which case the pin 183 is adjusted, for instance as inthe solid lines of Fig. 11, so as to pass beyond thepivot bolt on the side remote fromthe core 108. 'Ihe pin 183 and nger are adjusted to `diilerent distances from the lever 120, depending upon the number of transmitting stations omitted.

Instead of the mechanism of Figs. 11 to 17, which may move the stepping disk either forwardly or backwardly, we may prefer to use the gear mechanism of Figs. 31 to 37 which may step the stepping disk or gear 168 rearwardly any necessary number of increments.

In the signal transmitter of Figs. 31 to 37, the spring raised actuating lever 120' has an enlarged inner end provided with a wide arcuate slot 187 concentric Lwith the core 108 having gear teeth 188 on its side edge remote from the core. The stepping disk comprises a pinion 168 havingV peripheral gear teeth and is provided with the arcuate notch 170 receiving the outer nose, and is held in place by a retaining plate 189 secured over said pinion and provided with a large opening 190 exposing said

notches

124, 170 in all positions.

back until the long lug' A bracket 193 mounted on and offset from the back wall 109, carries a .shaft 194 (Fig. 32) mounted'between said bracket and the back wall and passingthrough said wide slot 187.

A driven member 195, 196 (Fig. 36) rotatably mounted on said Vshaft between said bracket and back wall comprises a cylindrical portion 195, and a small pinion 196 in mesh with the teeth 188 of saidwide slot.

A ring gear1198, 199 rotatable on said cylindrical portion 195 has'periphe'ral teeth 198 engaged with the teeth of the steppingv pinon 168', and a frontwardly disposed annular flange 199 having an inner recess 200 therein.

A frontwardly projecting pin or lug 202 on said cylindrical portion cooperateswith the shaft 194 to guide a slide bar 203 disposed in a plane frontward of the cylindrical portion 195 andhaving a longitudinal slot 204 receiving said lug and shaft, whereby the bar is constrained to move angularly when the member 195,l 196 rotates. Said bar carries a lock pin 205 passing through the slide bar and disposable in said recess 200.

A cam disk 207 adjustably secured stationary on said bracket 193 is provided in its rear falce with a

spiral groove

concentric land portions

Said groove receives said pin 205, and when the actuating lever pin is in the outer land portion 208 and recess 200 and rotates the ring gear an amount depending upon the distance the lock pin moves to reach the steep portion 210 of the groove, at which portion the lock pin moves into the inner land portion 209 and disengages ring gear, leaving the ring gear and the stepping pinion at this position, aspring 211 engaging the teeth of the ring gear to hold it and the pinion 168 in such postion.

120 moves down, the lock from the recess of thek Y bracket 193. This permits the steep portion'210 to be placed where it will disengage the pinV 205 and thus stop the stepping disk 168' after the outer nose notch 170 has moved the required numberrof increments. Thus the stepping disk or pinion may step the outerV nose any desired Vnumber of increments from one to nine by the time the lever 120 Fig. 3l. v Y

During the upstroke of the lever and the return movement of the pin 205, the pin again reaches the recess 200 and locks the ring gear to the members 195, 196. When on the return stroke of the lever, 120', the lever moves from reaches theV position 120:1l of the position of the lower dotted lines 1207to the position 120er, it is there stopped, as explained of the lever 120. Then the register is withdrawn, and the lever 120 and stepping disk 168 return to their original positions.

In the form shown in Fig. 38, the stepping disk or pinion 168 may be stepped either forward or backward the desired number of increments. In this form the spring raised actuating lever 120 is about the same as in Fig. 11, and a stepping disk 168' with peripheral gear teeth is about the same as in Fig. 31. n

The stepping mechanism is carried on a plate 220 adjustably pivotally mounted on said back wall 109, and comprises a shaft or pin 221 carry.- ing driven member 222, 223 mounted on the shaft and comprising a small pinion 222 and a large gear 2,23', the teeth of the latter being, in one position of said plate, in mesh withthe teeth of Vsaid disk 168'.V

An arcuate rack 125 pivoted to said lever is held by the spring 126 against the pinion 222 and therefore substantially coaxial with the core 108 and has gear teeth 227 on its side edge near the core and meshing with said small pinion.

A cam plate 230 mounted on said rack by means of bolts 231 passing through a slot 232 to be adjustable longitudinally of the rack, engages a control plate 234, pivoted on said pivoted plate and having a cam edge 235 engaged by said cam plate to throw the rack from said small gear, said control plate having a tooth 236 engageable with the teeth of said gear 223 to stop the pinion 68.

When the actuating lever moves down, the rack 225 rotates the pinion 222 and disk 168 an amount depending upon the position of the cam plate 230 and the distance the cam plate moves to reach the control plate to disengage the rack from the pinion, whereupon the control vplate 234 moves to stop the pinion and stepping disk at the position that they occupy when the rack is disengaged.

When the lever 120 returns to normal'position, the cam plate 230 disengages the control plate, permitting the rack to again engage the pinion 222, at which time, the tooth 236 disengages the gear 228 under the action of the spring 237; and when the lever 120 is restored to normal position, the stepping disk is also restored.

As above described, the disk was rotated in a counter clockwise direction. To rotate it forwardly we provide an idler gear 240 on said plate 220 permanently engaging with said gear 223. This gear and idler are so located on the plate 220 that the plate can be shifted to selectively exclusively engage the idler or the gear 223 with the stepping disk 168 to reverse the motion of the latter. A pin 241 carried by the plate 220 engages in one of two holes 242 and serves for holding the pivoted plate in adjusted position.

Operation of multiple transmitter system -The operation of the tour system of Fig. 18 will be readily understood from the foregoing and now need be only summarized as follows:

Beginning with the register conditioned to be received by the station 1 of the tour section ending in station A, the register is inserted in that station l and turned in a clockwise direction until it stops. On insertion the locking pin 58 and all of the tumblers 32 of the register are pushed back by balls 86 and released from perforations, and the inner nose is freely advanced in the notch 92 an amount equal to the angle between two rows of perforations, the lugs remaining stationary between the ribs 83, whereupon the tumblers snap into perforations of the next row. The register is then removed, and is in condition for the next station 2 of the same tour section. During this operation, the outer nose 21 is always locked, because the bumps 36 are remote from the pins 48, and the notch 93 is positioned merely to receive the outer nose if it is in proper position, but not to rotate it relative to the

lugs

27 and 39. The position of the notch 93 is the same for all stations of the same tour section.

This action is repeated for each

preliminary station

2, 3 and 4, which conditions the register for the semi-master station SM. The key is inserted in this station as in the other preliminary stations, but because of the long inner notch 92 and the sufficiency of balls 86, the inner nose may advance, in this case, iive increments, thereby to condition the register for station A.

The register is then insertedin station A and turned forward, carrying the long lug forwardly slightly until the tumblers thereof meet the balls and are released, whereupon the antifric tion ball 116 (Fig. 1) yieldably holds back the long lug one increment while the inner nose 1l engages the inner notch 124 and carries downwardly the lever or 120 (Figs. 11, 31 or 38) winding the clockwork. This action is continued until the lever is stopped against the pillar 148. At the same time, the bumps 36 release the pins 43, and the pin 183 (Fig. 11) or 205 (Fig. 31) or the plate 230, properly positioned causes the rotation of the

stepping disk

168 or 168 and the rotation of the outer nose 21 one increment.

The key is then released and the clockwork unwinds until one signal is sent and the signal wheel is stopped by the spring 162 (Fig. l). Later the button 165 is pressed and the other signal is sent.

During the unwinding the lever 120, the long lug 27 and the stepping disk 168 move back to initial position, and the noses retain their new position relative to the long lug.

Because the long lug has now been pushed back relative to the inner nose in the notch 124, the long lug strikes the shoulder 113 and holds the lever 120 against return until the register is withdrawn, whereupon the notches move back to their original positions, in which the noses in the new position cannot be received.

The operation of the rest of the tour system of Fig. 18 is similar to that just described except that the station E must advance the outer nose several increments, and there is no semimaster just before the station B. Before station B, the stations 6 to 9 merely continue to advance the inner nose in the same manner described of stations 1 to 5, thus conditioning the register for sta.- tion B.

When the register reaches station E, the

183 or 205 or the plate 230 which has been adjusted to turn back stepping

disk

168 or 168 the required amount, turns the stepping disk in a counter clockwise direction until the outer nose is conditioned for the tour section ending in station A. With the arrangements shown in Figs. 1l and 38, the transmitting station may be adjusted and adapted to move the outer nose either forwardly or backward; and when stations are omitted it is thus possible to move the stepping disk in that direction which requires the'least movement.

Single transmitter system The tour system of Fig. 19 requires only one transmitting station T shown in combination with tour sections a to i. In this system the watchman is required to come back to the same transmitting station after each tour section, and means are provided for moving both noses ll and 2l and also the stepping disk 168 (Fig. 20) one step each time the transmitter is operated, thereby to condition the register for the next section and to prevent the reuse of the transmitting station until the stations of said next tour section have been visited.

To this end, the stepping disk 168 (Fig. 20) is made completely rotatable against the actuating lever 120, has an opening received on said flange 123 and is provided with an arcuate notch 170 for receiving the outer nose 21. Around said disk is a series of frontwardly pointing pins 172 forming a ratchet wheel. A spring pressed advancing pawl 250 pivotably mounted on the lever is adapted to successively engage the pins and advance the disk and outer nose one increment near the i Operation of single transmitter system With the

notches

124 and 170 positioned to receive thenoses as the register comes from the tour `section a, the operation of the system of Fig. 19 is as follows:

The tour section a is completed as described of Fig. 18,- andthe register is inserted in station T Vand rotated forwardly thus bringing the bumps 36 against and unlocking the pins 43 and then carrying clown the leverY 120, setting the inner nose 11 forward one increment relative to the long lug 27 and winding and setting off the clock- Vwork as described of Figs. 1, 11 and 18. When the lever121 begins its downward movement, the pawl 250 engages a pin 172 and steps the disk 168 and outer nose forward one increment so that a pin 43 snaps into the next perforation 44 Y(Fig. 5) to lock the outer nose relative to the sho-rt lug 39 which is also held stationary by the stops. At this time the pawl 25 engages the pin 255 and is thereby pushed off ofthe pin 172. Thus the outer nose, after shifting one increment, then remains stationary, relative to theA short lug, inV the new position. However, there is only one perforation 45 (Fig. 6) on the longV lug member, and the long lug does not become fast with the short lug, and consequently the outer nose, until the long lug is broughtback, after the signals, .to position` ofv alinement with the short lug. The pawl 251 then yieldably holds the stepping disk against accidental displacement. Y After the completion of the two signals as previously described, both noses have been stepped forward one increment relative to the lugs, and the steppingdisk has been stepped forward one increment.l Y

It is noted that the inner nose has been stepped forward one increment relative to the long lug,

, and when the long lug returns to contact with the shoulder 113v (Fig. 1), the inner nose and its Anotch 124 are still one increment further ina clockwise direction and the notch 124 has there- Yto fore not returned to its original position. The key is then withdrawn with the nose in the advanced position, after which the clockwork unwinds further and restores the notch 124 to its original position whereit cannot receive the inner nose in its new position relative to the long lug vuntil saidnose is again vconditioned therefor-by successive.engagementV with the stations of the next tour section.

The operation of the next tour sections are similar tothe one described, and each tour section brings the long lug'back to the normal position relative to the inner nose, so that the inner nose may enter the notch 124 to permit the .register-` again to operate the transmitter and -advance the outer nose` notch an increment after each tour section, until vthe stepping disk has made a complete cycle as all of the tour sections have been visited.
