INKPWRITING TELEGRAPH-REGISTER.

To allfwhom it may concern: 1

Be it known that I, BENJAMIN Hum), a

citizen of the United States, residing at all parts, including particularly all means ofadjustment, so as to avoid any improper changes in adjustments by inexperienced and unauthorized personsl For example, in telegraph offices when this type of instrument is used, it is desirable that it be left for considerable periods in the absence of. the person in charge of the office, but a great source of trouble consequently arises due to change of exposed adjustments during these periods by unauthorized or unskilled persons. llowerer, if all adjustable parts he inclosed, the protection will be sufiicient to avoid trouble from this source.

Another important feature-of my invention relates to the inking mechanism where- 'by the necessity of constant attention by a skilled operator is avoided, the construction and mode of operation beingsueh as to se newal of the ink supply except at very long intervals. -Moreover, with my improved in-. '5 1 strumengqthet constructlon 18 such that no fpalrticul'ai' skill 'or expertness is required in ing drawings.

renewing' t'he ink" supply, as has been necessary heretofore. I also secure the advantage of-a self-Wmdmg mechanism, thus overcom- I ing the necessity-of attention by the operator to the instrument in this respect.

The fulfilment of other objects and ad-.- vantages secured by my invention will be understood .by those skilled in the art from the fOllowingdeseriptionand accompany.-

line 33 of Fig. 2; Fig. 4 is an end elevation with parts of the casing removed; Fig, 5

is a detail View; and Fig. 6 is a diagramshowing the electrical connections.

The instrument is lnelosed 1n a main eascasing 2 inclosing parts of the feeding and inking mechanism, the face of which casing is closed by a glass plate 3. From the main casing extends an arm 4 for supporting the paper reel 5 In a circular opening formed in theback plate 6 of the casing and closed by a cover 6 is located a main gear 7 which supports from itsarms suitable disks 8 for inclosing' and separating coiledsprings 9. I prefer to use duplicate main springs on account of the more uniform pressure and action obtained. The outer ends of the springs 9 are secured to one of the pins 10 fixed to the gear 7 and which also serve to support the disks 8. The inner ends of the springs 9 are fixed to a sleeve 11, which is movable about the main supporting shaft 1-2. The gear 7 drives a pinion 13, which inturn drives through its shaft a gear 14 fixed to the same shaft. The latter gear drives a pinion 15 fixed to a parallel shaft' upon which is also fixed a ratchet wheelf16. The wheel 16 is engaged by an oscillating escapement or regulator 17, which limits the speed of the feeding mechanism. Upon the shaft driven by pinion 15 is formed a spiral groove by means of a wire 18. The inner end of this wire extends a.

-ing 1, and upon the face thereof is a similar carried by a lever 20, one end of which is .supportedon a shaft 21 and retained in any desired position thereon by the adjustable shaft and forms a stop for the feeding mechanism when engaging the cross pin 19 collar 22. A spring 23 is secured at one end to the lever 20 and extends dowiiwardly therefrom and to one side thereof, being secured at its lower end to the front portion of'the casing. The lever 20 at its inner, end

carries a downwardly extending pin 24:.

which engages the spiral groove formed by the wire '18. Thus when the lever 2 0.is raised and its pin disengaged from its groove, the spring 23 willsnap the lever toward the frontof the casing and draw the pin downwardly into engagement with the groove at .a point nearerthe front of the casing. The pin 19 being thrown out of engagem'ent from the stop engaged thereby,

will release the feedingmechanism and as" the shaft revolves, the pin 24 will be caused to travel in the spiral groove until the end :of. the lever 20 is carried to such position that the pin 19 will check the operation by engaging the projection from the shaft. The lever 20 will be raised or tripped by each dot "or dash impulse sent over the line, and in the present case is arrangedfor operation. by either of two different circuits.

At the right of the mechanism'thus far described, and fixed to a support extend ing; between the two sides of'the-casing, are located two pairof electro-magnets 26, 26',

. 27 27 The cores of these magnets extend vertically and the cores of magnets 26, 26

are connected at their base by a strip of soft iron 28, and the cores of magnets 27, 27 are similarly connected by another iron strip 28. 4. The movable armatures 29, 297 of the two pair of magnets are respectively carried by extensions 30, 30 and'a're adapted to be separately or simultaneously operated. Theextension-30' is fixed to'a shaft 31, which latter extends through the front part of the casing and has fixed thereto at its front end a yieldable strip 32 carrying an ink wheel 33 at its lower end. The extension 30 is fixed to a sleeve 34 mounted to turn freely on shaft 31. The sleeve 34 extends through the excitation of magnets 26, 26, the sleeve 34' will be turnedslightly and cause the ink .wheel 33 to be pressed against the tape; at

. one side of the record made by the wheel 33.

- The extension 30 which, as before stated, is

fixed to shaft 31, carries an upwardly extending part 35, which-in turn carries a rod or pin'36, the outer end of-which extends below a cross pin-37 carried by the lever 20. The extension 30 carries a part 35' similar to the part 35 and also carries a' rod 36, the

lower end of which extends under the cross pin 37 attached to the lever 20. Thus when either armature 29 or 29 is attracted, the lever 20 will be raised or tripped by reason of engagement of the parts just described. The cross bar 38 carries the adjusting means and stops for each of the parts 35, 35.- The extension 35 is limited and controlled by a hollow screw 39 which has a screw-thread engagement with the bar 38 and extending toward the part 35 as shown. This screw serves as a stop for the movement of the armature 29 and prevents actual contact with the cores of its magnets and so avoids the possibility of the armature being held by residual magnetism. A second screw. 40 has a threaded engagement with the hollow screw 39, as shown, and the position of this screw controls the tension of a spring 41 located in the lower end of the screw 39 and pressing againstthe outer end of the extension 35'. It will thus be seen that by turning screw 39 the limiting position of armature 29' is controlled and by turning screw 40 the pressure against the extension 35' is controlled and consequently the force tending to raise. armature 29 from its magnets against the cross bar or stop 42. The

controlled and limited part 35 is similarl by similar parts 39 40 and 41.

The winding mechanism comprises a pair of vmagnets 43, 43' located below the two .pair of magnets already referred to. The

coils of the magnets 43, 43 are connected at their outer ends by a soft iron piece-.44

which extends beyond-the magnet cores and forms a support for the magnets by connection at the ends of the iron part 44 to the casing, as indicated in Fig. 1. Fixed to the shaft 12 already referred was carrying the main gear 7, is a clamping member 45 carrying at its outer end an armature 46 for e magnets 43, 43". The armature 46 normally rests below the face of the magnets and when the latter are excited, the arma-- ture 46 will be attracted upwardly, giving corresponding rotation to the shaft 12. The

armature 46 is connected by a spring 47 to the end of an adjustable screw 48 passing through a cross bar 49 and the armature is therefore normally held in its lower posi- 50 which carries a pivoted pawl 51, one end of which engages a ratchet wheel 52 fixed to thesleeve 11 already referred to as having the innergends of the springs 9 connected.

thereto. The-opposite end of the pawl is engagedby aspring 53 connected to the extion. Fixed to the part45 is an extens1on tension 50 and tending to hold the pawl 51 in engagement with its' ratchet wheel 52. The movement of the part 45 and extension 50 in one direction caused by the spring 47 is limited byan adjustable screw '54, which engages the lower end of the extension 50 I and is adjustable in the cross bar 49, as desired. The cross bar 49 is split longitudinally and the two parts are held together by screws 55 which also serve to clamp the adjustable screws '48 and 54 firmly in any desired position of adjustment. The cross bar.

38 is similarly split longitudinally, the screw 55'- serving to hold the twoparts together to clamp the screws 39, 39 in any desired position of adjustment. A'supportingpart 56 fixed to the front portion of thecasing and engaging the shaft 12' at one end carries a pawl 57- 'which is pivoted ratchet wheel 52 and is constantly held in engagement therewith by the spring 58 con- -to the support 56.. The p'awlfi? engages the nected to one endv of thepawl and to an extension from the support The pawl their normal positions and cause the ratchet wheel 52 to be rotated corresponding'with the number of teeth previously passed over by the pawl 51. The ratchet wheel 52 by its rotation will increase the tension of the springs 9 and the wheel will be held in its new position by the pawl'57. Thus every excitationof the magnets 43, 43 will cause an attraction of the armature 46 and re sultant rotation of-the ratchet wheel 52 a certain amount and therefore wind the Springs 9 a certain amount. This action is repeated each time the operators key closes the circuit, thus tending to always maintain the springs 9 under considerable tensionl The feeding and inking mechanism will now be more particularly described; The shaft driven by the pinion 13 extends through the front portion of the main casing, and in addition to carrying the gear 14 also carries-and drives the knurled wheel 59 fixed to the shaft in front of'the main portlon of the casing. Above this wheel is located another knurled wheel 60 carried the pivoted arm 61 at the other, serves topress the wheel 60 against the tape 63, whole passes between thewheels 59 and 60. The wheel 59' serves as the driving means for the tape and the wheel 60 by its pressure serves to cause the feeding of the tape through the instrument. From'the reel 5 the tape 63 passes through" an opening in the auxiliary casing 2, under a sheet metal support 64 fixed to the casing, then engages a hook 65, and thencepasses over an idler 66, from which it passes over the feed wheel The support 64 serves to carry 0r fix in position the ink, well 67 and also carries an extension 68-which embraces the roller 66. and serves as -a guide for the tape. 1 The 1nk supply device comprises the well 67 having a perforated cover 69 which sup- 7 ports'a-comparatively large, flat feeding wick 70 of 'felt or other suitable material,

'and an opening 71 isprovided in the cover which servesas a convenientmeans for introducing ink to the well whenever required. I The wick 70 is shown in Fig; .4 as having two extensions which are each en.- gaged' respectively by one of the ink wheels '74,.and then to the line.

stood from the above, but it may be stated 1125 through the electro-m-agnets 27, 27' causes: J

33, 33. The extension 68 which embraces the tape and the roller 66 is provided with two openings, one opposite each of the ink wheels 33, 33. Thus when either of the ink wheels is shifted in position by the mechanism already described, each will be forced through an opening in the shield 68 and make pressure against the tape and. roller 66. Atthe same time the ink wheel is 1nain-,

tained in contact with the ink feeding wick 70, the movement of the tape causing the ink wheel or wheels to revolve, thus keep-i ing the periphery of each wheel well coated. Also. by reason of the tape being carried by the roller 66 at the point or points where the ink wheels are applied thereto, the tape is rigidly supported, which, together with the action of the ink wheels results in. a clear and well-defined record of the impulses sent over the line being obtained.

Also, by reason of the capillary attraction ofthe ink in the well 67 through the wick 70, the ink wheels will always be well supplied. I prefer to provide the upper portion-ofthe wick 70 with two extending portions, one in engagement with each of the ink wheels, as shown inFig. 4. It will be seen-that the ink well is readily removable from its support for the purpose of refilling when'necessary or for adjustment of the wick.

Itwillbe understoodfrom the above that the instrument is adapted to give two different recordsindependently of each other or simultaneously when either one or both of the line circuits are closed and opened by the -operator.- The electrical connections are indicated in Fig. 6 Current from one 'line is adapted to pass to terminal 72 through a cut-out plug '73, thence through the coils 27, 27 of one pair of electromagnets, and then through thecoils 43, 43- of the self-winding mechanism to terminal It will be noted that the terminals and cut-out plugs are conveniently located ,on the face ofthein- .strument below the inking device. Current from another linecireuit is adapted to pass from terminal 72 through cut-out plug 73, thence through the coils 26, 26" of the other pair of electro-magnets, and then through the coils 43, L3 to' the terminal 7.4, and, then to the line. It will thus be seen that when eitherof the line circuits is closed, the electro- magnets 43, 43 will be excited in each case and cause the windin fmechanismtobe operated, as above descr1bed.'

The operation will doubtless be under-f 1 in general that the closing of the circuit the lever- '20, which releases the, feeding mechanism as above described and causes the f it tape to be fed through the instrument. At

the same time, as long as the magnets 27, 27 4 are energized, the ink wheel 33 will be pressed against the tape causing a dot-qr dash to be recorded thereon, depending upon the length of time the circuit is closed. At the same time this circuit is closed, the circuit of the electro-magnets' 43, 43' is-closed causing the winding mechanism to be actuated. The feeding mechanism will continue to operate until the lever 20 has been re-- turned to its original position, but of course each excitation of the magnets will causecurs when both pair of electro-magnets are operated simultaneously.

It will be seen that by my improved mk-I ing mechanism and relation of its parts,

' that the continual attention of the operator is avoided, and that a well-defined record is obtained. a

It will also be evident that the structure and relation of the parts ofthe instrument aresuch asto secure compactness, reliability 3 in operation, and that the parts are well protected.

It will also be seen that'the mechanism relieves the operator from a any attention in this regard. j
