Patent No. 677,801, dated July 2, 1901.

Serialhlo. 735,933. (No model.)

.tially shown in Fig. 6. Upon the shaftF are fixed two ratchet-wheelsfand f, as shown in Figs. 3 and 5, the teeth of each of the said ratchet-wheels corresponding in number and arrangement with the figures or characters of the type-wheel.

B is a pawl pivotally connected near one 0 end with the armature-lever B and provided near the other end with a tooth which is adapted to engage with the ratchet-wheel fand turn the type-wheel E an interval each time the magnet A is energized; 'A light spring I) tends to hold said pawl in position to engage with said ratchet-wheel. The outer end of the pawl is bent downwardly and inwardly, forming a stop b, which when the armaturelever is attracted engages with a tooth of the ratchet-wheel f after it has been turned by the tooth of said pawl, thereby arresting the movement of the type-wheel in exactly the proper position for printing one of its figures or characters. 'lhe inner or opposite end of said pawl is extended and bent upwardly, so that when it is drawn toward the magnet it will by engagement with an incline or stop 12 on the magnet-frame hold the stop I) at the outer end of the pawl in position to properly 0 engage with the ratchet-wheel f. The armature-lever B is'drawn and normally held away from the magnet by a spring 13*, and its movement is limited by two adjusting-screws b 12 between which it plays at or near its upper end. When the lever B is drawn away from the magnet, the innerupturned end of the pawl B engages with the inclined head of a pin b projecting from the magnet-frame, and throws the tooth of the pawl out of range with Ice the teeth of the ratchet-wheel f to allow the type-wheel to be turned back to its'initial position.

G is a lever fulcrumed near its lower end to a suitable fixed support and pivotally connected at its upper end with a horizontally-slid ing rod H, one end of which projects into the path of the armature-lever B. of said rod is provided with a check-piston h,

which works in a cylinder H, as shown in- Figs. 1 and 3. The lever G is provided with a contact g, which is normally held in engagement with a fixed contact 11 by a spring 9', attached to the lower end of said lever. The contact-1; is mounted upon an insulated post I.

J is a shaft arranged parallel with the shaft F and provided with a ratchet-wheel j, a worm j, and a toothed paper-feeding wheel 7' as shown in Figs. 1 and2.

D.is a pawl pivotally connected at one end with the armature-lever D and formed at the other end with a tooth which isadapted to engage with the ratchet-wheel j and intermittingly' turn the shaft J. Said pawl is yieldingly held in engagement with said ratchet-wheel by a spring (Z, as shown in Fig. 4:, and it is formed with a supplemental tooth or stop at, which is adapted to preventthe overthrow of said ratchet-wheel when the armature-lever- D is rapidly vibrated. Both the pawls B and D are constructed and arranged to operate in a manner similar to that of escapeinents used in clock-movements and other well-known mechanism. The ratchetwheelj is held from turning backward by a dogj (Shown in Fig. 4.) The upper end of the armature-lever D plays between two adjusting-screws d d which serve as stops to limit its movement. A spring D attached to the lower end of said lever, draws it away from the magnet O and normally holds it against its outer or back stop.

K is a reel upon which the strip or band of paper is wound. It is supported upon a standard K above the feeding-wheelj k is a roller having a corrugated periphery, of rubber or other elastic material, against which the teeth of the wheel j press the band of paper.

is a paper-guide through which the band of paper passes underneath the type-wheel E.

e is an inking-roller made of felt or other suitable soft absorbent material. It is yieldingly supported by spring-arms c in position to bear against the faces of the type or characters on the type-wheel. The machine may be provided with additional inking-rollers if necessary or desirable to effectively ink the type and produce a clear impression of the characters upon the paper.

L is a segment-gear engaging with a pinion Z on the shaft F. Z is a spring attached at one end to said gear and constantly tending to turn the type-wheel backward to its initial position in a direction opposite to that in which it is turned by the setting-magnet A.

M is a circuit breaker or controller arranged The other endin the circuit of the printing-magnet O and consisting, as shown in Fig.;t, of a horizontal rod movable endwise in a suitable bearing, on opposite sides of which it is provided with disks or heads m m. It is adapted to be moved back and forth for alternately closing and breaking the circuit through the magnet C by a compound lever N, the lower end of which plays between the disks m m, and the upper end of which is engaged by a pin on the pawl D. The two members of the compound lever are connected bya spring n, which operates when said members are carried in either direction slightly past a straight line to quickly and positively complete their movement in that direction. \Vhen carried to the extreme limit of its movement toward the armature-leverD, the circuit-breaker M engages with a fixed contact 0,-carried by an insulated post or support 0.

Pis a rock-shaft supported in suitable bearings parallel with the shafts F and J. It is provided near one end, opposite the armature-lever B, with a downwardly-projecting armp and near the other end, opposite the armature-lever D, with an upwardly-projecting arm p. To the arm 19 is pivoted one end ofa rod 19 the other end of which is guided by a suitable bearing in position to be engaged bythe point of an adj usting-screwp", carried by the lever B, as shown in Fig. 3. To the arm 19' is pivoted one end of a rod 19, the other end of which is guided by a suitable bearing in position to be engaged by the point of an adjusting-screw p carried by the lever D, as shown in Fig. 4. Upon the shaft P is mounted, in line with the typcwheel E, an upwardly-projecting arm 19 and in line with the ratchet-wheel f an upwardly-pro.- jeeting arm 13 Q is a horizontally-disposed impression-lever, one end of which extends below the typewheel E and terminates directly opposite the center of said wheel in a small platen q. At its opposite end it projects through the uppert'orked or looped end of the arm 13 and is formed in its upper side with an elongated depression q, as shown in Fig. .5. It is pivoted or fulcrumed between its ends to a suitable support. The looped or forked end of the arm 19 carries a small roller 19 the journals of which are held and guided in oblique slots in the sides of said arm. The depression q in said lever, the roller p and its oblique slotted hearings in the arm 19 are so proportioned and arranged with relation to each other that when the arm 13 is turned inward toward the type-wheel the roller 19 will drop into the depression q, allowing the platen q to drop and rest just below the paper-guide 7c, and when said arm is turned outward away from the type-wheel said roller by engagement with the shoulder at the outer end of the depression q will suddenly throw the platen g at the opposite end of said lever upward, and thereby force the strip of paper against the opposing type on said wheel; but

as soon as said roller clears said shoulder its journals will freely move into the upper ends of their inclined slotted bearings, thus allowing the platen to drop back into its normal position, as seen in Fig. 5.

R is a horizontally disposed lever fulcrumed between its ends to a suitable support and extending transversely across the machine from the ratchet-wheel f',with which it is adapted to engage, to the arm 10 which is looped or slotted to receive it, as shown in Fig. 5. It is formed or provided at the end next to said ratchet-wheel with a downwardlyprojecting tooth 1, which by engagement with said ratchet-wheel serves to hold the typewheel against backward rotation. It is formed near its opposite end on the upperfside with an elongated'depression r. A spring'r attached' to said lever and bearing against the lower end of the loop or slot'in the arm 19, tends to hold the tooth r in engagement with the ratchet-wheel f. Said ratchet-wheel is formed or provided on one side with an elongated tooth, pin, or projection f which is adapted by engagement with the tooth r when the latter is raised, as shown in Fig. 5, to stop the type-wheel in its return or backward movement'and to hold it in its initial or zero position. The depression r in said lever is so proportioned and arranged with relation to the arm 19 and to the depression q in lever Q that when the arm 11 is turned outward or away from the ratchet-wheel f the tooth T will be raised out of engagement with said ratchetwheel just after an impression is made by the platen q and said platen has returned to its initial position, but not before. The outer end of the lever B is bent upward or formed with a shoulder, which serves as a stop to limit the outward movement of the arm 19 and its connections.

S is a vertically-disposed lever pivoted between its ends on a line parallel with the shaft J to a fulcrum-block s, which is inturn pivoted to a suitable support on a line transverse to said shaft, so that the upper end of said lever is movable both transversely to and lengthwise of said shaft. 8 is a spring con nected with the lower end of said lever and tending to move its upper end at the' same time toward the worm j and toward the wheel Said lever is provided near its upper end with a pin or projection' which is adapted to be engaged with the worm j. Near its lower end said lever is formed with an incline adapted to be engaged by the inner end of a horizontally disposed screw 3 carried by the rock-shat t P.

T is a vertically-disposed lever fulcrumed near its upper end to a suitable support on a line parallel with the reciprocating rod of the circuit-breaker M. It is formed or provided at its lower end, as shown in Figs. 2 and 4, with an incline or wedge 15, which is adapted to be forced between the disk m of said cir cuit-breaker and the opposing support or bearin g, and thereby prevent the engagement of said circuit-breaker with the contact 0. To the upper end of said lever is pivoted one end of a rod 23, the opposite end of which is slotted and loosely engagedvby a pin projecting horizontally from the upper end of the lever S. v

The several parts hereinbefore described are preferably mounted upon a metal plate U, which is in turn attached to a base V, of wood or other suitable insulating material. The base V is provided at one end, as shown in Fig. l, with two binding-posts o and c and at the other end with a single binding-post v The magnets A and-O are preferably made adjustable, so that theymay be moved toward and from their armature-levers B and D. As shown in Figs. 3 and 4:, these adjustments may be made by means of the screws a and c, which pass through posts or standards on the base-plate and are provided on each side thereof with nuts.

Referring to Fig. 8, showing suitable circuit connectionsfor the receiving instrument in connection with transmitting instruments, as before stated, the posts I and O, carrying the fixed contacts 't and o, are insulated. The movable contacts of the circuit-breakers G and M are electrically connected with each other through the metal base-plate U, as indicated by the line 2 in Fig.8. 3 designates a normally closed main circuit or line, including abattery or source of current at, a relaymagnet 5, and break-wheels or signal-transmitting instruments 6 and 7. Sis a local circuit including a battery or source of current 9, the spring-retracted armature-lever 10 of the relay, and the back-stop ll of said lever. One wire of this circuit is connected with the vbindingpost o and the other with the binding-post 'u', said binding-posts being connectedwith opposite ends of the winding or coil of magnet A. The binding-post o is also connected with the insulated post I. The binding-post r is connected with one end of the winding or coil of magnet O, the other end of said winding or coil being connected with the insulated post 0. Said binding-post r is also connected by an outside wire or conductor with the pole of the battery 9, opposite that which is connected with the binding-pesto.

The receiving instrument, as hereinbefore described, with circuit connections, (shown in Fig. 8,) operates as follows: Assuming that a signal is sent in by the break-wheel 6, which has two groups of two and three teeth each, I

the lower ends of their inclined slotted bearings in said arm 19" and carrying the upper end of the looped arm 19 into the depression 0", thereby allowing the tooth on the opposite end of the lever B to descend into engagement with the ratchet-wheelf. At the same time the inner end of the screw 3 is moved downward into engagement with the incline on the lower end of the lever S, thereby throwing the pin or projection near the upper end of said lever out of engagement with the wormj and allowing the spring 8 to throw the upper end of said lever back toward the wheel 3' At the same time the pin at the upper end of the lever S, engaging the end of the slot in the rod 15 next to the-wheel 3' withdraws the incline or wedgeat the lower end of the lever T from engagement with the disk m, thereby allowing the spring n of the compound lever N, which normally occupies the position shown in Fig. 8, to carry the circuit-breaker M into engagement with the contact 0, thus closing the circuit of magnet G at that point; but before or as soon as the circuit is thus closed by the circuit-breaker M the circuit of magnet O is broken by the armature-lever B, which as soon as 'the magnet A is energized operates through the rod H to force the contact 9 out of engagement with the contact 2'. In making two complete vibrations, as above stated, the armature-lever B, operating through the pawl B, turns the type-wheel E two intervals, thus bringing the figure 2 thereon directly opposite the platen q in position for printing. The interval between these vibrations is so short that the contact g, checked in its return movement by the piston h on the rod H, cannot engage the contact 2' and close the circuit at that point for magnet 0 until the type-wheel is turned into position for printing the desired figure and the armature-lever B comes to rest. When this occurs in the interval between the two groups of figures on the break-wheel, the contact g is gradually returned by the spring 9' into engagement with the contact 'i, thereby closing the circuit at thatpoint for magnet O, which is thereupon energized, the circuitbreaker M having been closed, as above explained. The circuit of said magnet 0 may be traced as follows: Beginning with the battery 9 the current passes through the binding-post 2), post I, contacts i and g, lever G, base-plate U, (indicated by the line 2 in Fig. 8,) circuit-breaker M, contact 0, insulated post 0, coil of magnet O, binding-post '0 and thence back through the external connection to the opposite pole of said battery 9. The magnet 0, being thus energized, first operates through its armature-lever D, pawl D, and ratchet-wheelj to turn the paper-feeding wheelj an interval, and immediately following said operation it acts through the rod 10 to turn the shaft P, with its arms 1) and p outward or away from the type-wheel. As the roller p occupying its lower position in the oblique slots of the arm 19, is forced over er /386i the shoulder at the outer end of the recess q it suddenly throws the platen g at the opposite end of the lever Q upward against the paper, forcing the latter against the opposing type or character (in the present case the figure 2 on the type-wheel, thereby producing an impression of the character upon the paper. As soon as said roller passes over said shoulder the platen (1 immediately drops into its initial position, the opposite and shorter arm of the lever Q lifting the roller 19*, the journals of which are now free to pass into the upper ends of their oblique bearings, as shown in Figs. 5'and 8. Immediately after the impression is made and the platen q allowed to fall, as above explained, the upper looped end of the arm 13 passesout of the depression 1' upon the raised outer end of the lever B, thereby lifting the tooth r at the opposite end of said lever out of engagement with the ratchet-wheel f, and thereupon the spring Z, acting through the segment-gear L and pinion Z, turns the type-wheel E back to its initial or zero position. The type-wheel is stopped in its initial position by the pin or projection f on said ratchet-wheel engaging with the tooth 1-, as shown in Fig. 5. The movement of the shaft P, above mentioned, throws the inner end of the screw 8 upward out of engagement with the incline near the lower end of the lever S, thereby allowing the spring 8 to carry the pin near the upper end of said lever into engagement with the worm j. The attraction of the armature-1ever D by the magnet O shifts the position of the compound lever N and of the circuitbreaker M, momentarily breaking the circuit through the contact 0. The spring D thereupon retracts said armature lever, which reverses the compound lever and circuitbreaker, closing the circuit through the contact o. The magnet C is again momentarily energized, and the operations above explained are repeated and the paper fed forward until the circuit through said magnet O is again broken by the separation of the contacts g and 7}, which occurs in the manner hereinbefore explained, when the first of the next group of teeth'on the break-wheel 6 breaks the main circuit 3, temporarily closing the 10- cal circuit 8 and energizing the magnet A. The type-wheel E is set by the operation of magnet A and its connections to print the figure 3, and the impression of that figure is made upon the paper by the operation of the magnet O in the manner above explained. After the last figure or character .is printed and the break-wheel which has transmitted the signal comes to rest the armature-lever D continues to vibrate, as above explained, feeding the paper forward out of the machine, so that the printed record of the signal may be conveniently examined outside of the case or cover, which in. practice is employed to inclose the machine, but is not shown in the drawings. The worm j being thus turned in engagement with the pin on the lever S car- IIO ' D ceases to vibrate and is held by the spring D in engagement withits back-stop (2 as shown'in Fig. i. In this position of the armature-lever the'compound lever N is held in the position shown in'Figs.4 and 8, so that when the circuit-breaker M is released by the lever T it will be thrown by the springn into engagement with the contact 0, as hereinbefore explained. i

By varying the length of the slot in the arm tthe length of paper which is fed out ofthe instrument after printing a complete number or series of characters may be varied as de sired. In practice the machine is made and adjusted to turn out about eighteen inches of paper after each record is made.

WVhen the instrument is used in connection with a short main line supplied with sufliciently strong'current, it may be connected directly with the main line, thereby dispensing with the local battery and relay, and by a slight change in the mechanism the instrument may be adapted to work on a normally open as well as on a normally closed circuit.

I do not wish to be understood as limiting my invention to the precise details of construction and arrangement herein shown and described, as they may be variously modified within the spirit and intended scope of the invention.
