EDWARD E. KLEINSCHMAIDT, OF BROOKLYN, NEW YORK, ASSIGNOLR TO KLEINSCHMIL'DT ELECTRI'GCOMPANY, INC., OF BROOKLYN, NEW YORK, A CORPORATION 0F NEW Yoan.

Application filed April 14, 1916, Serial No. 91,027. Renewed July 20, 1922. Serial No. 576,362.

10 all 'w hom t may concern Be it known that I, EDWARD E. KLEIN- SCHMIDT, a citizen of the United States, residing at New York city, borough of Brooklyn,

in the county of Kings and State of New York, have invented a new and useful Improvement in Telegraph Printers, of which the following is a specification.

My invention relates to a printer which is operated by signals received from a printing telegraph system. While this printer is herein described as operating in connection' with a Synchronous system, such as the Baudot, l do not wish to limit the present invention to this particular use as the improvements herein disclosed may be applied to printers used in any other telegraph system.

The purpose of my invention is to provide a simple and direct method of selec-ting and operating the type-bars' of the printer, also to'provide a means for operating the figure shift directly from the type-bar mechanism, a means for quickly and positively returning the carriage at the end of a line, a simple method of operating the line feed, a direct mechanical method of operating a signal bell and the reperforator control contacts, and other improvements in the construction of a tele-graph printer.

ln a synchronous multiplex telegraph system, in connection with' which the printer is herein described, commutating devices usually termed distributors, which operate in synchronism, are placed at each end of the circuit. Each commutator is usually divided into sets of segments, one set for each printer to be operated. These .setsof segments in connection with the transmittingv and receiving apparatus, are usually termed channels. ln the drawings l have shown dia? grammatically the commutator of a synchronous multiplex system having Yfour channels as represented by the four sets of segments.

The printer as herein described, operates with a combination of five impulses. However, any uniform length code may be used. rThese impulses operate a line relay. the contact of which is connected to the brush of the commutator. One set of the commutator segments is 4shown connected to the selector magnets of the printer. The brush ofthe comm'utator in traveling over these segmentsdesignates Y one side of which distributes the impulses received to the proper magnets. In the printer each selector magnet controls a corresponding selectorbar. The selector-bars are slotted in accordance with the code. lVhe'n any combination of from one to five of the magnets is energized to operate the selector-bars, a certain set of slots in the bars will assume positions opposite one another. A series of intermediate bars is provided controlling the typebars and functions of the printer. When the selector-bars are set, o-ne of the intermediate bars drops into the slot then presented and places a corresponding hook connected to a type-bar in position to be operated.

After .the commutator brush has passed over the five segments and the letter is selected, a circuit is closed through an operating magnet, which acts toprint the selected letter and restore the selectors to their normal position, as will be described later.

The code used in the printer herein described is similar to what is known as the Baudot To operate the printer any type of transmitter may be used, such as a transmitter controlled by perforated tape or a storing transmitter, as is ldescribed in my application Serial No. 1,546, filed January 11` 1915.

In the following description of my invention, reference is made to the Aaccompanying drawings` which form a part of the specification and wherein: Figure 1 is a side elevation of the complete printer; Fig. 2 a front view of the operating mechanism; Fig. 3 a.

plan view of the operating mechanism and the ribbon-feed mechanism; Fig. 4 a View showing the carriage-operating mechanism; Fig. 5 a side sectional view taken through the line a2- of Fig. 3; Fig. 6 a detail view showing the circuit closer for the line-*feed solenoid; Fig. 7 a detail View of the line feed mechanism; Fig. 8 a detail of the ribbon-feed mechanism; Figs. 9 and 10 details showing the construction of reperforator icontrol contact device; Fig. 11 a detail showing the construction of the bell-operating mechanism; and Fig. 12 a diagram showing the circuit connections of the printer. Similar reference numerals indicate similar parts 'in the several views.

Referring to the drawings the letter A the main frame of the printer, is partly broken awayto more clearly show the parts and B designates the frame of the type-bar operating mechanism. 1 designates the type-bars which are supported in a basket oitl circular form as is common in type-bar printers. So as to show the printer more clearly, I have shown only one of the type-bars in Fig. 1. The type-bars are pivoted on a rod 2 and have connected to them levers 3 pivoted on a rod 3 mounted in the frame. Pivoted at 4 on the levers 3 are a series of actuating bars 4, here shown as hook-bars. To operate the type-bars-` I provide a universal operating bar 5 which is mounted on an armature lever 6 pivoted in bearings 7. The free ends of the actuating bars 4 rest on intermediate bars 8 and are normally out of the path of the operating bar 5. The intermediate bars 8 are pivoted on a fulcrum 9 and are pressed against the under-side of a universal restoring bar 10 by the springs 11. Beneath the front ends of the intermediate bars 8 are placed the selector-bars 12, which arel slotted at the top. the slots being arranged in accordance with the code selected t0 operate the printer. As shown in Fig. 2, the selector-bars 12 slide in the frame 13 and are normally pressed against latch pins 14, which engage notches in the under-side of the bars, by the springs 15. The latch pins 14 are set into armatures 16 and are pressed into the latching position by the springs 17. The magnets 19 act on the armature 16, when energized, to withdraw the latch pins from the corresponding selector-bars. When the selector bars are thus released, they are drawn against the stop 18 by the springs 15.

To restore the selectorbars 12 to the latched position, I provide a restoring lever 20, which acts upon all of the selector-bars 12. The lever 20 is fastened to an armature 21 which is acted upon by a magnet 22. The restoring universal bar 10 is fastened to a pivoted lever 23, (Fig. 5).` A spring 24 acts on the lever 23 to press the bar against the intermediate levers 8 with sutcient force to overcome the tension of all the springs 11 and press the front end of the intermediate bars 8 aga-inst a universal stop bar 25. To the lever 23 is connected a rod 26, which extends upward and is acted upon by the armature lever 6.

Each of the tive selector-bars 12 represents a unit of the code. By setting the tive selector-bars in various positions, thirtyone different combinations can be made eX- clusive of the normal or restored position. The slots in the upper side of the selectorbars are so arranged that in each of the thirty-one different settings, there will be an alinement slot in a different place, which will in each instance be directly under one of the'thirty-one intermediate bars.

`I will now explain the manner in which the mechanism just described is operated electrically from impulses at the line relay.

Referring to the diagram, (Fig. 12) letter C designates the line relay, which is polarized. The liue normally carries negative current and I have shown the armature normally resting on the negative side. When positive ilnpulses are received the armature closes the circuit on the positive side. The line relay C is operated by impulses received over the line wire 137 which connects with suitable transmitting apparatus to properly time the impulses as herein,l described.

The commutator of a four-channel distributor 27, has an outer ring, which divided into four sets of segments, the segments of each set being numbered 1, 2, 3, 4 and 5. One set of these segments represents one channel and is connected to the printer. The other three sets of segments may be connected to other printers or transmitters as desired. 28 designates a revolving arm carrying contact brushes 291, 292, 293, 294. At the transmitting station there is a distributor, not shown here, having a commutator 27 with similar segments, revolving arms 28 and contact brushes 291, 292 293, 294. Arms 28 of both receiving and sending station revolve in synchronism. Synchronous distributors of the type herein described are well known in the art and it is, therefore, not necessary to describe how they operate.

The terminal marked 7 of the battery D is connected to the contacts of the printer, while the terminal marked 1L is connected to the magnets of the printer. To complete the circuits of the magnets, it will be necessary to describe only the circuits between them and the contacts. The magnets 19 are connected to corresponding segments 1, 2, 3, 4 and 5 of the commutator 27. The commutator segment 30 is connected to a relay 31 by a wire 32. The contact 31 of the local relay 31 is connected to the operating magnet 33 by a wire 34. To hold the contact 31 closed for sutlicient time to insure the proper operation of the operating magnet 33, I provide a. locking circuit 35 for the relay 31. which is controlled by contacts 36. One of the contacts 36 is carried by a lever 37. A spring 38 acts on the lever 37 to hold the contact 36 closed. To the lever 37 is also fastened one of the contacts 39, which is included in the circuit of the restoring magnet 22. Contacts from each other.

lThe screw 40 is fastened in a projection of the operating bar 5 and the screw 41 is fastened to a projection of the restoring universal bar 10. IVhen the operating bar 5 is in the normal position as shown in the drawings, the screw 40 presses against a latch bell-crank 42 to disengage it from a stud 43.

36 and 39 are insulatedl The selection and operation of the type bars by the mechanism and circuits described is as follows:

The armature 140 of the line relay C is connected to the brushes 292 through a collector ring 295. Vhen a combination of impulses is received at the line relay C. as for instance for the selection of the letter A. which in the code herein used is 1 and 2 positive and 3, 4 and 5 negative. the tongue of the relay will be held on the closed or positive side during the interval of the 1 and 2 positive impulses and on the other side during the interval of the 3, 4 and 5 negative impulses. While the armature of the relay C is closed on the positive side, the brush 29 is traveling over the contacts 1 and 2 connected to the magnets 19. The first and second of the selector magnets 19 will then be energized and the corresponding selector bars released in the manner described. The energizing circuit for the selector magnets being as follows-froin the negative side of the battery D to the contact of relay C; from the armature of relay C to the ring 29, brush 292 to 29; one of the segments connected to the selecting magnet 19, and from the latter to the positive side of the battery D.

After the brush 29 has passed over all of the five segments, the inner brush 293 connects with the segment 30 and closes the circuit of the relay 31, which in turn closes the circuit of the operating magnet 33 through the contact 31 and wire 34. The armature 6 will then be attracted by the magnet 33 and swing the operating bar backward. The armature 6 in traveling downward will depress the plunger 26 there-- by opera-ting the lever 23 to raise the restoring universal bar 10. The intermediate bars 8 are now free and their front ends are pressed on the selector-bars 12. One of the intermediate bars 8 controlling the actuating bar 4 connected 'to the type-bar carrying the letter A', will now be drawn into the slot presented by the selector-bars previously set, thus raising the actuating' bar 4 in the path of the operating bar 5. When the armature 6 has completed its motion downward, the screw 41 will press the lever 37 forward to open the contacts 36, thus breaking the locking circuit of the relay 31. The contacts 31, will then open and break the circuit of the operating magnet 33 to allow the armature to assume its normal position so thatl the universal operating bar 5, as clearly shown in Fig. 5 of the drawings. may engage one of the actuating bars 4, when positioned in its path. The. engaged actuating bar 4 is operated on the back stroke of the universal bar 5 by the contraction of spring 6 which has been expanded on the forward stroke of bar 5, at which, as it were, power has been stored'in spring 6. The tension of spring 6 can be regulated and adjusted by means of screw 62, secured in bracket 63. This regulation or adjustment of the tension of spring 6 controls obviously the force of the back stroke of universal bar 5, and, in turn, the force of the printing stroke of the type bars and its resulting manifolding power.

Yhe-n the lever 3T is pressed forward by the screw 41 it also closes the Contact 39 of the restoring magnet 22, which is connected thereto by the wire 138 which is then energized to restore the 1 and 2 selectors to their normal position. The lever 3T does not immediately return when the screw 41 recedes. but is locked into the forward position b v the latch arm 42 pivoted on the frame at 42. Then the operating bar 5 has returned to its forward position, the latch arin 42 releases latch 43 allowing the contact lever 3T to move forward to open the contact 39 and close the contact 36. The purpose of locking the lever 37 is to retard the action of the resetting magnet 22 so that the intermediate bars 8 may be withdrawn from the slots of the selector-bars 12 before the circuit of the magnet 22 is opened. The intermediate bars 8 are withdrawn from the slots of the selector bars before the printing operation `is completed, to permit the setting up of a new combination of selector bars 12 before the previously selected character is printed.

Referring to Fig. 1, 44 designates the car riage of the printer, ywhich is supported on suitable bars 45 and 75, and travels horizontally thereon. Supported in the carriage is a paper-feed-roll 48 which also acts as striking platen for the type as is common in typewriters. Attached to the. frame of the carriage is a rack 49, more clearly shownin Fig. 4. Engaging with the rack is a gear wheel 50. The gear 50 is fastened to a shaft 51, which also carries two ratchet wheels 52 I and 53. The teeth of these two ratchetwheelsare cut in reverse directions with respect to each other. v

The mechanism shown in Fig. 4 is for the purpose of stepping the carriage forward each time a letter is printed and also for restoring the carriage to its normal or start ing position at the end of the line. A. `band 54 is wound about a spring-drum 55 and is l att-ached to the carriage to draw it to the'v starting position. Engaging the ratchet wheel 52 is a feed-pawl 56, which is carried by a walking beam 57 to the opposite end of which is connected 'the plunger 58 of the spacing solenoid 59. The feedpawl 56 turns the ratchet wheel 52 and through its connection with the. shaft 51, gear 50 and rack 49 forces the carriage forward against the tension of the spring-drum 55. To feed the carriage forward the solenoid 59 is energized. which acts to draw the feed-pawl 56 upward and on deenergizing the magnet, the spring 60 acts to throw the pawl 56 downward, turning the ratchet wheel 52 to feed the carriage 44. The retaining pawl 61 engages the ratchet 52 to hold it in position when the pawl 56 is withdrawn during the feeding operation. To return the carriage yfor starting a new line, I provide a -solenoid magnet 62 which acts on a plunger 63, connected to a lever 64. EX- tending from the'lever 64 is a projection which acts on the retaining pawl 61 to withdraw it from the ratchet 52 when the lever 64 is operated. Carried by the lever 64 is a feed-pawl 66. rI"he lever 64 is pressed upward by a spring 67 and holds the pawl 66 normally out of engagement with the ratchet wheel 53. When it is desired to return the carriage for starting a new line both the magnets 59 and 62 are energized thus releasing the feed-pawl 56 and retaining pawl 61 from the ratchet 52, and allowing the carriage to be drawn to its starting point by the spring in the drum 55. To accelerate the starting of the carriage, I provide the feed-pawl 66 and the ratchet wheel 53. When the solenoid 62 is energized the plunger 63 draws the lever 64 downward causing the pawl 66 toy engage with the ratchet 53 to give it a quick starting impulse which may be as powerful as desired by varying the power of the solenoid 62.

To withdraw the feed-pawls 56 and 66 from the ratchet wheels when they are raised, I provide adjustable stops 56 and 66'.. The upper portion of the feed-pawl hasfan inclined surface which when the vfeed-pawl is raised strikes against the stop and turns the pawl about its fulcrum to withdraw it from the ratchet wheel.

To-space the paper for a new lineI provide a solenoid magnet 67, which is lfastened to the frame of the carriage 44. The plunger 68 of the solenoid 67 is connected by a U-shaped Jframe to a. lever 69 by a pin 68', which bears against a slide 70. A spring 71 acts on the slide 70 to press the lever 69 and through it plunger 68 to the retracting position. To the slide is attached a. feedpawl 72 `normally out of engagement with a ratchet wheel 73 attached to the paper-feedroll.y When the solenoid 67 is energized the feed-pawl7 2 is pressed forward and engages the ratchet 73-,turning the feed wheel to feed the paper for printing a new line.

To shift the position of the feed-roll printing platen 48 for the purpose of printing letters or figures or upper or lower case characters, I support the feed-roll in brackets 74 and a sub-frame 44 having a depending arm 442 carrying a roller 443 that normally' rests on a bar 75. The bar 75 is carried by a bell-crank frame 76. To the lower end of the frame 76 is connected a bar 77 similar to the bars 4 The bar 77 rests on an intermediate bar 8a. When the former is selected by the operation of the selecting mechanism,

it is 'brought into engagement with the operating bar 5, which draws it forward carrying with it theI frame 76 and thus raising the bar 75 and through the sub-frame 44 the printing pla-ten or feed-roll 48. To hold the printing platen or feed-roll in the set position, I provide a bell crank 78 to which is connected a bar 79 that rests on an intermediate bar 8b, as shown in Figure 5. When it is desired to drop the printing platen as for printing letters, the intermediate bar 8 is operated to raise the hook end of the bar 79 into the path of the operating bar 5. which will draw theI former forward and disengage the bar 78 from the frame 7 6.

The spacing solenoid 59 is energized each time a character is printed or the paper is to be spaced forward. To insure its proper operation, I provide a universal bar 80 that is acted upon by a projection 1 of the typebar 1. The universal bar 80 operates a contact 82 to close it each time the type-bar projection 81 is lbrought against the universal bar 80.

To space the paper forward without printing a. character, I remove the type from the type-bar that is selected by the spacing-signal. In this case the bar is brought to a stopagainst the projection 83 instead of by the type striking the paper.

To insure a contact of suiiicient duration to properly operate the line-spacing magnet 67, I providethe contact mechanism shown in FigV 6. The contacts 84 are held normally open by the spring 85 and the weight of bar 86. ',Ihe actuating bar `87 has a projecting pin 88 which bears against the movable portion of the contacts 84. The actuating bar 87 is connected to bar 86 by a lever 89. The bar 86,-actuating bar 87 and lever 89 are similar in construction to and operate in the same manner as respectively, theI typebars l, connecting bars 3 and actuating bars 4. The actuating bar 87 rests on an intermediate bar 8c and is-operated by the operating bar 5in the same manner as the bars 1, but does not carry any type. The purpose of using this construction for operating the contact 84 is to take advantage of the inertia of the parts 86, 87 a'nd 89 to prolong the contactof the points 84.

To insure proper operation of the carriagereturn mechanism, I provide a locking mechanism for the contacts 90, in the circuit of the carriage-return solenoid 62 and spacing-solenoid 59, shown in Figs. 2 and 4. One ofthe contacts 90 is carried by a bellcrank 91,'which rests on an intermediate bar 8d and is operated thereby. Projecting from the bell-crank member 91 is a pin 92 which loa is engaged by a locking member 93 when the bell-crank'is raised. The locking member 93 is connected by a shaft 93 to a finger 94 that projects into the path of the pin 95 mounted on the spring-drum 55 shown in Figure 4. When it is desired to return the carriage the proper signal is transmitted which raises the intermediate bar 8d beneath the bell-crank member 91, closing the contacts 90. The locking member 93 will then engage the pin 92, which acts to hold the contact 90 closed. Contacts 90 are connected to the carriage-return solenoid 62 and the spacing-solenoid 59 by a wire 96 (Fig. 12). As previously explained when these two solenoids are energized the carriage is released and drawn to its starting point by the action of the spring-drum 55. The pin 95 is set at a point on the spring-drum so that when the carria e cornes to its rest position, the pin 95 wil strike the finger 94 and releasethe locking member 93 from the pin 92', thus opening the circuit through the solenoids 59 and 62. v c

For the purpose of calling the attention of the operator to the machine, and to provide a means for communicating between the transmitting and receiving operators by code signals, I provide a bell 97 and striker 98. The rod carrying the striker 98 is mounted in a bearing 99 and has connected to it an arm 100. A rod 101 similar to rod 109 shown in Figure 5 engages the arm 100 and extends from it to a position in front ot one of the actuating bars 4, where it passes through a plate 102, supported on bellcrank bracket 103, the latter being connected to the bell-crank lever 76 by a link 104. These parts are so adjusted that when the carriage is in thel lower position as for printing letters, the plate 102 is raised, carrying the rod 101 out of the path ofthe actuating bar 4, while when the carriage is raised as for printing figures, the plate 102 is lowered to carry the rod 101 into the path of the actuating bar 4 to be operated thereby to sound-.the bell 97. When the operator at the distant end wishes to `operate the bellsignal, he first sends the code of signals to raise the carriage for printing figures and then se-nds the code yof signals that will operate the actuating bar 4 that is opposite the"k rod 101, which, as previously described will i sound the bell.

For the purpose of connecting with the receiving machine, a reperforator or other auxiliary apparatus, I provide a contact 105, which is operated by a lever 106, setting lever 107 and bar 108. he two latter are operated by rods 109 and 110, respectively, which are similar to rod 101 and are also supported by the plate 102. Similar to the rod 101, rods 109 and 110 are out of the path of the actuating bars 4 when the carriage is lowered as for printing letters. When the operator at a distant end wishes to either open or close the contact 105 of the receiving machine, he first sends the code of signals to raise the carriage for, printing figures and then sends the code of signals that will operate the actuating bar 4 that is in front of either the rod 109 or 110.

To feed the inking ribbon 117 and automatically reverse its motion, l provide ribbon-spools 111 and 112, on which the ribbon is first wound in the usual manner. The ribbon-spools 111 and 112 are carried by vertical shafts 139 and 140 which connect with horizontal shafts 113 and 114 carrying ratchet wheels 115 and 116. The inking ribbon 117 passes over rollers 118 and 119, which are carried by arms 120 and 121 fastened to vertical shafts 141 and 142 supported in the frame. A rod 122 connects the arms 120 and 121. A spring 123 is connected to an arm extending from the lever 121. The pivot of 121 and the anchorage of the sprin 123 are placed in relation to each other so t at they are in alinement when the lever 121 is in its central position. A lever 124 is loosely mounted on the shaft 142 and carries two pins 125 and 126 that are in the path of the lever 121. A lin'k 127 connects the lever 124 to a triangular piece 128, whichl rocks on a pivot. Two links 129 and 130 extend from the triangular piece and engage p the feed-,pawls'131 and 132, and retaining pawls 133 and 134, which engage ratchet wheels 115 and 116. The Jfeed-pawls 131 and 132 are connected to an arm 135 that is connected by a shaft 143 to the universal bar 80. The tension of the spring 123 draws the lever 121 to either one side or the other, carrying with it the lever 124, and through the link 127 holds one set of feed and retaining pawls in engagement and the other set out of engagement with their respective ratchet wheels As previously mentioned when a type-bar is operated, projection 81 strikes the universal bar 80 to operate it, which in turn operates the feed-pawls 131 and 132 through the previously described mechanism, which will in turn operate the ribbon-feeding mechanism as described. As is shown in the drawings, the ribbon is winding on the spool 111 and is nearly unwound from the spool 112. When the ribbon is completely unwound from the spool 112, the continued winding of the ribbon on the spool 111 will cause it to draw forward the lever 121, the ribbon being anchored on the hub of the spool 112. The lever 121 will be carried forward until the relative position or its fulcrum to the anchorage of the spring 123 is carried to a point where the spring 123 will tend. to draw the lever 121 to the extreme opposite position. By striking the pin 126, the lever 121 will carry with it the lever 124, which will, through the connecting link 127, raise the feed-pawl 132 and retaining ,pawl 133v from engagement with the ratchet wheel 115 and lower the feed-pawl 131 and retaining-pawl 134 into engagement with the ratchet wheel 116, which will then be operated by the motion of the universal bar 80, to Wind the ribbon on the spool 112, thus reversing the movement of the ribbon.
