' Im rovements in Ty e-WVriting Machines, of

which the following is a specification.

My invention relates to typewriting machines and more particularly to means for notifying the operator when the paperfeeding devices or feed rollers are in the released or inoperative osition.

In machines iaving means for locking the feed rollers in the released or inoperative position, operators, after looking the feed rollers in the released position in order to adjust the paper, frequently forget to restore the feed rollers to normal or operative position before proceeding with the writing. In consequence the paper will not be fed at all or will be fedunevenly and the sheet will be spoiled before the o erator realizes he has forgotten to unlock t e feed rollers. So frequently has this occurred that in some cases it has been deemed advisable to dispense with the use of means for locking ofl the feed rollers, notwithstanding the fact that the provision of such means is highly desirable in order that the operator may have both hands free to adjust the paper.

One object of my invention is to overcome the difficulties pointed out above and to provide simple and efficient means for notifying the operator when the feed rollers are locked off.

A further object of my invention is to provide means for locking the machine or a portion thereof out of operation when the paper feeding devices or feed rollers are locked in the released or inoperative position.

A still further object of my invention is to provide automatically acting locking means to prevent actuation of the printing instrumentalities when the paper feed devices or rollers are locked in the released or inoperative position; so that the operator will be compelled to restore the feed devices or rollers to the operative position before any writing canbe done, the printing instrumentalt ties being automatically released by the act of restoring the feed devices or rollers to the normal or operative position.

Another object of my invention is to rovideq'neans of the character specified w rich may be readily applied to existing forms of typewriting machines without changing the structure of said machine.

Still another object of my invention is to provide an operative connection between the feed rollers or paper feeding devices and a line-lock mechanism so that the line-look mechanism may be under control of the paper feeding devices.

To the above and other ends yvhich will hereinafter appear my invention consists in the features of construction, arrangements of arts and combinations of devices to be heremafter described and particularly pointed out in the appended claims.

In the drawings, wherein like reference characters indicate corresponding parts in the different views, Figure 1 is a on and, vertical, front to rear, sectional view of part of a Monarch typcwriting machine, and showing certain features of my invention applied thereto. Fig. 2 is a rear elevation of the'upper portion of the machine shown in Fig. 1, certain parts being omitted. Fig. 3 is a fragmentary plan view of a portion of the machine with parts broken away to better illustrate other features of construction. Fig. 4 is an enlarged end elevation of the upper portion of the machine, the parts being shown in normal position. Fig. 5 is a like view with parts omitted and showing the feed rollers locked in the inoperative position and the machine locked out of operation. Fig. 6 is a detail fragi'nentary perspective view of a modified form of construction embodying my invention.

I have shown my invention in connection with a Monarch machine to which the invention'may be applied without modifying the structure of said machine when equipped.

with the feed roller locking mechanism disclosed in the application of Herbert ll. Steele, Serial No. 301,620, filed February 17th, 1906,

though it should be understood that the invention may be applied to other styles of typewriting machines, and may be used in connection with different means for locking the feed rollers in the released position, and to this and other ends various changes may be made without departing from my invention. v

The frame of the machine comprises a base 1, corner posts .2 and a top plate 3. Key levers 4 are fulcrumed against a fulcrum plate 5 and each key lever is provided with a finger key 6 and a restoring spring 7 An upright sublever 8 is pivoted at 9 to each key lever and is slotted at the lower end portion thereof, at 10, for cooperation with a fixed fulcrum rod 11 that extends beneath the key levers and is secured at its ends in the base 1 of the machine. The upper end of each sub-lever is pivoted at 12 to a forwardly extending link 13, which in tur'nis pivot'echat 14 to a type bar 15. Each type bar is pivoted at 16 to a hanger 17 secured to a type bar segment 18 by a screw 19. Each type bar is restored to normal position by a spring 20 connected at one end to the type bar and at its op osite end to a plate 21. The forward en s of the segmentally arranged upwardly and rearwardly striking type bars are supported by apad 22 which is carried by a segmental support 23 secured to the type bar segment by rods 24. The type bar segment 18 may be shifted by the usual means (not shown) in order to provide for upper and lower case writing. Extending upwardly from the top plate are brackets 25 to which fixed

guide rails

26 and 27 are secured by screws 28. The guide rails 26' and 27 are grooved on the inner faces thereof for cooperation with antifriction balls 29 which are likewise received in oppositely disposed grooved rails 30 connected y webs 31to form a carriage bar which, with the forwardly extending end plates 32, constitute a platen frame or carriage which supports a revoluble platen 33. The carriage is thus supported by the antifriction balls 29 and is adapted to travel from side to side of the machine in the usual manner.

The carriage has rearwardly extending arms 34 pivoted thereto at 35, said arms carrying a feed rack 35 at the rear ends thereof. The feed rack 36 cooperates with a feed pinion 37 secured to the forward end of-a shaft mounted in a bearing 38 secured to the top plate of the machine. The rear end of. the

shaft is operatively connected in the usual manner to an escapement wheel 39 with which feed dogs 40 cooperate. The feed dogs are mounted on an upwardly extending arm 41 of a dog rocker which is pivoted at 42 to depending bracket secured to the top plate of the machine. A restoring spring 43 a is connected at one end to the bracket and at the other end to the dogrocker and returns the dog rocker and the parts connected thereto to the norm al position. 44 projects from the dog rocker and a link 45 has its upper end connected at 46 to said arm, the lower end of said link being pivotally connected at 47 to a rearwardly extending arm 48 ofa universal bar frame 49 pivoted at 50 in the base of the machine and carrying a universal bar 51 that extends beneath the various key levers 4. The link 45 carries a sleeve 52 adjustably secured thereto A forwardly extending arm 5 by a set screw 53 and projecting laterally from this sleeve is a lock member or pin 54. A locking lever 55 is pivoted at 56 to the lower fixed carriage rail 27 and is adapted to move transversely of the machine, as indicated in Fig. This locking lever is pivoted between the fixed carriage rail 27 and a swinging line lock actuating bar or bail 57 which has rearwardly extending armsor ears 58 at the ends thereof. Screw pivots 59 pass through openings inthe arms 58 and take into threaded holes in the ends of the fixed guide rail 27 to pivotally connect the swing ing bar to the rail. A spring 60 is secured by ascrew 61to the carriage rail 27 and extends at its free end beneath a pin 62 secured to the bar 57, so as to normally maintain the bar in the elevated position shown in Figs. 1, 2 and 4. The left-hand side of the rocking lever 55, as viewed from-the front of the machine, is rovided with an arm-"63 that extends to t 16 left over a pin 64:Wlll0h projects rearwardly from the bar 57. The lower end of-the locking lever 55 is provided with a hook-like member 65 which is adapted to pass beneath the locking member or pin 54 when the bar 57 is depressed, as indicated in dotted lines in Fig. 2. When the locking lever is in this dotted line position the two members 54 and 65 co-act to prevent a downward movement of the link 45, thereby looking the universal bar 51 in elevated position, thus preventing ,a depression of any of the character keys and preventing an "operation of the printing instrumentalities. and also locking the escapement mechanism against actuation. That is to say, the universal bar is locked against actuation so that the key" levers and type bars cannot be actuated and the dog-rocker is prevented from being v1:- brated and the escapemcnt mechanism cannot therefore be actuated.

The locking mechanism thus far described constitutes portions of the line-loclrmechanism of the Monarch machine which are fully disclosed in the patent to Jacob F elbel and Carl Gabrielson, dated May 13th, 1902, No. 699,796. The means, for actuating the bail or bar 57 when the end of a line is reached have not been shown as a consideration of such means is unnecessary for an understanding of the present invention, but it should be understood that the means in' question may cooperate with the bar 57 m the usual manner without interfering with the operation of the bar in a manner to be hereinafter described.

Upon reference to Figs. 4 and 5 it will be seen that'the usual paper table 66 is employed to direct the paper to a paper apron 67 supported by ears 68 on a rock shaft 69 which is received in bearings in the end plates 32 of the carriage. Forwardly extending curved arms 70 are pivoted-at 71 to bracket arms or lugs 72 formed on the carriage bar,

coarse and carried by the forward ends of these sure thus exerted by the sprin s 76 and 95 arms is a shaft 73 which supports a forward through the arms 89 exerts a set of feed rollers 74 that are adapted to project through cut-outs or openings 75 in the paper apron and to contact with the platen.

A spring 76 is secured by a screw 77 to each arm 70 and bears at its rear free end against a portion of the carriage bar, as indicated at 78 in Fig. 4, in order that the spring may exert an upward pressure on the arms to maintain a forward set of feed rollers under pressure against the platen. Each arm 70 has a leaf spring 79 secured thereto by a screw 80, the forward free end of each spring bearing against the paper apron and tending to force it into contact with the platen. A platen scale or plate 81 (Figs. 3 and 4) is pivoted at 82 to forwardly extending arms 83 secured by screws 84 to forwardly extending lugs 85 on the carriage bar. Leaf springs 86 have their ends secured at 87 to the arms 83 and hear at their forward free ends against rearwardly extending fingers 88 connected to the platen scale 81. Arms 89 are pivoted above the arms 70 at 90 to the forwardly extending lugs 72 and said arms support a rod or shaft 92 at the lower end portions thereof. This rod 92 supports the main feed rollers 93 which are adapted to project through open ings or cut-outs 94 in the paper apron and contact with the platen. Each arm 89 has a leaf spring 95 secured thereto by a screw 96, the upper free end of'each spring bearing against a pin 97 so that pressure is exerted by said springs to force the main feed rollers 93 towards and into contact with the platen. The lower end of each arm 89 carries an antifriction roller 98 which bears against the as sociatedarm 70, so that a movement of the main feed rollers 93 away from the platen causes a corresponding movement of the forward set of feed rollers 74. Each of the arms 89 is provided with an upwardly extending lug 99 with which a projection 100 on the rock shaft 69 is adapted to cooperate during the movement of the rock shaft in one direction to force the

feed'rollers

93 and 7 4 away from the platen and to relieve the pressure of thesprings 79 on the paper apron. An oppositely disposed projection 101 is carried by the rock shaft 69 opposite each feed roll hanger ar 89. These projections have flat engagin ends for cooperating with the arms 89 so that when the rock shaft is turned from normal position to the position indicated in Fig. 5 the

feed rollers

93 and 7 will be moved away from the platen to the inoperative position, as indicated in Fig. 5, pressure of the springs 79 on the paper apron will be relieved, and the fiat ends of the lugs 101 will be brought to a position where the flat upper sides of the feed roll hanger arms 89 will be pressed against them in the dead center position, or in the direction of the axis of the rockshaft. The preslooking force which maintains the rock shaft in the position to which it has been turned. An actuating arm 102 is secured to the left-hand end of the rock shaft 69 and the outer end of said arm is provided with a finger piece 103, with which to manipulate the rock shaft. The normal position of the finger piece 103 is indicated in Fig. 4, two stop pins 104 and 105 being provided to limit the swinging movement of the arm 102 and the movement of the parts controlled thereby.

From an inspection of Fig. 4 it will be seen that a forward movement of the finger piece 103, until the arm is brought into contact withthe forward stop pin 105, is effective to move the feed rollers away from the platen and against the tension of the springs 76 and ing turned to the position shown in Fig. 5

which is effective to move the feed rollers to the releasing or inoperative position and to lock them in such position in the manner hereinbefore described. The paper feed devices or mechanism thus far described are the same as those disclosed in the application of Herbert H. Steele hereinbefore referred to. Y

A crank arm 106 projects from a sleeve 107 which is secured'to the rock shaft 69 by a set screw 108. The rear end of the crank arm 106 has pivoted thereto at 109 a depending link or actuating device 110 which extends through a perforation in a guiding bracket 111 secured to the lower guide rail 30 of the carriage bar, as shown inFigs. 3 and 5.. The lower end of the link or actuating device 110 is immediately above the bar 57, and a downward movement of the part 110 will always swing the bail 57 irrespective of the position of the carriage. From an inspection of Figs. 4 and 5 it will beunderstood that a forward movement of the finger piece 103 to temporarily release the feed rollers will merely result in lifting the crank arm 106, thus lifting the link 110 without. affecting the bar 57, so that the locking devices which lock the machine out of operation are not actuated during this temporary release of the paper feeding devices. "Nhenever the finger piece 103 is moved rearwardly to the position shown in Fig. 5 to lock the feed rollers or paper feeding devices out of operative position, thecrank arm 106 will be moved downwardly thus effecting a downward movement of the link 110 which results in the swinging bail or bar 57 being depressed as shown in ,Fig. 5 and this downward movement of the bail causes the pin 64 to be carried down with it, thus freeing the locking lever 55 and enabling it todrop by gravity to the dotted line position in Fig. 2, when the engaging members 54 and '65 will be brought into cooperation to prevent an actuation of the machine. The eflect of the actuation of the bar 57 in the manner just described is the same .as that effected-by the line lock mechanism at the end of the line. In other words, the movement of the locking lever 55 from the full to the dotted line position-in Fig. 2 in the manner just described results in looking the link 45 against downward movement so that the finger keys, the printing instru'mentali'ties, the universal bar and escapment mechanism are all looked out of operation and the operator is unable to write until the feed rollers have been restored-to the normal or operative position, which results in the link 110 being elevated to the position shown in'Fig. 4 and the line lock mechanism will be restored to normal position; the locking lever 55 being moved to the full line'position shown in Fig. 2, thereby automatically unlocking the ma chine and enabling the operator to proceed with the writing.

When I refer herein to means for locking the machine out of operation I Wish to be understood to mean any device or means which will prevent an operation of the ma; chine or a part thereof in the usual manner, so as to notify the operator that the feed rollers or paper feeding devices are in the inoperative position. Thus, for instance any suitable looking or warning means may be actuated by the bail 5.7; or a bail 57 g. 6) corresponding to the bail 57 may b fixed to the lower fixed rail 27 and serrated or toothed on the upper edge 57* and the link 110 may be provided with a tooth at the lower end so that at the last part of its downward movement it will be brought into engagement with the upper serrated edge of the fixed bar 57* and thus lock the carriage against movement when the feed rollers locked off. Should the operator attempt at this time to actuate the machine, it will be found that the carriage is locked against movement and thus the operator is warned or notified that the feed rollers are locked in the inoperative position and should be released. In such a construction, .while the printing instrumentalities are not actually looked against movement the carriage is, and a printing operation can take place at only one letter space point.

When I refer in the accompanying claims to means for notifying or warning the operator when the feed rollers or paper feeding devices are locked in the released position I mean to include any means which may be effective for that purpose, whether they accomplish the result by looking a part or parts of the machine out of operation as herein shown and described or accomplish it by some other means. I believe that I am the first to attain this end and wish to be understood as broadly claiming means for accomplishing this purpose, and also to be understood as broadly claiming means for preventing a printing operation when the paper feeding devices are out of operation. It will be understood, therefore, that various changes may be made without departing from my invention.
