chines, of which the followinglis a specification. i

- call T actuated means for renderin the movements of the printing keys inoperative to actuate the printing instrumentalities, as for instance, when the carriage reaches the end of a line, thus preventing the pilingup of the characters at the end of a line.

The main object of my invention, generally stated, is to provide comparatively simpleand efficient mechanism of the character specified.

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

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure l is a fragmentary, central, vertical, fore and aft sectional view of one form of typewriting machine embodying my invention, suificient parts only of the machine being shown to illustrate my invention in its embodiment therein. Fig. 2 is a fragmentary, detail, side elevation of some of the parts shown in Fig. 1, the parts being represented in different positions from those in which the corresponding parts are shown in Fig. 1. Fig. 3 is a fragmentary, front elevation of the machine with parts in section. Fig. t is a fragmentary transverse sectional view of one of the contact devices for the controlsame in the carriage in a conventional manner.

\The frame of the machine comprises a base 1, corner posts 2 and a top plate 3. The top plate supports fixed oppositely grooved guide rails 45 which receive antifricti'onballs or rollers 5, and these rollers are likevi' isereceived in oppositely grooved rails 6. The rails 6 constitute the forward and rear cross bars of a carriage '7. The carriage is thus mounted for movement from side to side of the machine over the top plate. Acylindrical platen 8 is supported in the carriage in any suitable manner. Arms 9 are pivoted at 10 to lugs 11 which project upwardly from the rear cross bar of the carriage, near the ends thereof. These arms support a feed rack 12 which meshes with a feed pinion 13. The feed pinion is fixed to the forward end of a shaft 14: mount ed to turn in a bearing 15, secured to the top plate of the machine. The rear end of the shaft 14 extends beyond the bearing 15 and has a doubleescapement wheel 16 secured thereto. The escapementwheel may be of the character employed in the No. 10 Remington machine, a single feed dog 17 cooperating therewith. The feed dog is carried by a. dog rocker 1 8, pivoted at 19 to rearwardly extending bracketarms 20 carried by a bracket plate 21, secured to and depending from the top plate. A forwardly projecting arm 29. projects from the dog rocker and has a downwardly extending link 23 connected therewith. The lower end of this link is connected to a rearwardly extending crank arm 24 which projects from a rock shaft 25 mounted at its ends in suitable bearings in the base of the machine. Therock shaft also has, near the ends thereof, rearwardly projecting crank arms 26 connected to depending links 27 which support a universal bar 28, the latter extending beneath the series of key levers 29. A contractile spring 30 is connected at one end to a pin 31 projecting from the dog rocker, whereas the opposite end of said spring is connected to an arm 32 secured to the bracket plate 21. This spring returns the dog rocker and universal bar to normal position shown in Fig. 1. It will be understood that each down and up movement of the uni- "applied thereto by the usual, spring drum (not shown).

The key levers 29 are fulcrumed on a fulkey 36. Each key lever has an upwardly extending projection 37 with a vertically' disposed slot 38 therein. The lower end of each slot is extended rearwardly to form an off-set engaging notch 39. upwardlyextending actuating link 40 cotiperates with each key lever and is provided at its lower end with an engaging device or pin 41 received .in the slot" 38 of theasspciated key Q lever 29. Each pin extends between arms formed by the lower bifurcatedend of its associated actuating link. Each pin 41, as [will be seenfrom a comparison of Figs. 1 "and 2, is adapted to move in the verticalslot i Z 01 the'associated key lever, or to be received in the engaging notchor opening 39'ain the .leVer. The upper end of each actuating link I} --is pivotally connected to a sub-lever 42 pivoted at 43 to. a hanger 44. The rear end of each sub-lever is connected to a link 45 which in turn is connected at its rear end to a type bar 46. Each type bar is pivoted at 47 to a hanger 48 secured to a type bar segment 49 and the type bars are segmentally arranged on the segment to move upwardly and rearwardly to strike against the front face of the platen 8. Each of the actuating links 40 extends through an opening 50 in a controlling device or member comprising a horizontally disposed flange or bar 51 which extends transversely of, the machine across and above the system of key levers. An upwardly extending flange 52 is formed as a 1 part of the bar 51 and is provided with for- 5 wardly extending e'ars'53 at'the ends there-i of; -These ears are pivoted at 54 to bracket arms 55, secured to the-base of the machine. ,In this manner the bar 5152 is pivotally asupported for movement fromfthe position shown in Fig.- 1 to that indicated in Fig. 2,

or vice versa. The openings 50 in the bar or controlling member are such as to afford a free longitudinal movement of the actuating 1 links duringthe operation of the type bars under control of the finger keys. When,

' however; the controlling bar is moved from the position shown in Fig. 1 to that indicated in Fig. 2, it is effective to swing the links around their upper pivoted ends, thus moving the lower ends of the entire set of actuating links transversely and toward the front of-the machine, to carry the pins. 41

- thereon ou't of the engaging notches 39 and into the lower ends of the slots 38. It'will 6 v be understood-that at this time an actuation of any of the fingerkeys 36 is ineffective to transmit movement to the. associated actuating link 40 and the type bar controlled thereby; the-pin 41' playing freely in the vslot 38. The effect therefore of moving the bar 5152 from the position shown in-Fig; 1 to that indicated in Fig. 2 is to disconnect the printing keys 36 from the type bars or to aflord a lost motion between the parts; whereas a movement of the bar in the opposite direction or toward the rear of the machine is efi'ect-ive to seat the pins 41 on the various actuating links in' the engaging notches 39 in the key levers, thus reestablishing operative and positive connection between the finger keys and the type bars;

The bar 51-52 is automatically controlled by the travel of the carriage, so that when the carriage reaches the end of a line for instance, said bar will be moved to theposition shown in Fig.2, thereby automatically disconnecting the printing keys from the printing instrumentalities or type bars.- Any suit-able means may be employed etc 1 bring about the automatic actuation ofhlthe bar 51-52. In the present instance I have shown means similar to the line lock devices employed in the No. 10 Remington machine,

for'ettecting an actuation of the bar. Thus an adjustable stop or contact device 56 is supported-on the front cross bar of the carriage for adjustmentthereon in the direction of-the travel of the carriage. This contact device is adapted to cooperate with an up- .4 .Wardly extending contact device "57 mounted on the frame of the machine. From an inspection of 'Fig. 4 it will be. observed that this contact device 57 is fixedly mounted on a trunnion-like pivot '58 which is received in bearings 59 and 60 of a bra'cketwhich is secured by screws 61 to a front fixed carriage rail. An expansion spring 62 is received in the bearing 59 and bears against a'fixed abutment at one end and against the bottom wall of a recess in one end of the pivot 58. The pressure of this spring is exerted to move the contact device ,57 axially of its pivot 58 and to the right, Contact walls 63 co-ac't with the contact device v57' to limit its movement to the left after a movementhas been transmitted thereto corresponding to a single letter space movement of the carriage. The contact device 57 is maintained normally in engagement with contact walls 64 by the pressure of the spring 62, said Walls limiting the movement of the device 57 .to the right. It will be understood that the contact device 57 is mounted for axial as well as for pivotal movement around the pivot 58, the axial movementbeing effected in one directionagainstthe pressure of I the spring 62." The pivotal movement of the contact device is eflected by a finger piece 65 connected directly therewith and ar ranged "at the front. of the' machine 'where and at its lower end to an upwardly pro-' it convenient for actuation. The part 57-65 is restored to normal position around its pivot 58 by the spring 62. A depending portion 66 is formed on the contact device 57 and this depending portion is slottedat 67 for the reception of a bent end 68 of a connectin link or rod 69. The rod 69 extends to t e left and is received in a groove or cut-out 70 in the bottom of the forward fixed guide rail. The left-hand end of" this rod is connected to an angular lever 71, pivoted on a shouldered 'pivot screw 7 2, carried by the left-hand forward bracket which supports the forward guide rail 4. A depending link 73' is connected at its upper end to the angular or bell crank, lever 71,

jecting ear 74 formed on ,/the flange 51 of thercontrolling bar or member 51-7-52 at one end thereof. It will be understood that the carriage i its mov nent from right" to left is effective to bring t'e contact device 56 into engage ment with the contact device 57, moving the latter to the left. This movement of the contact device, 57 takes place after the operator has been notified' by the usual alarm mechanisnynot shown, of the approach of the'carriage to the end of the line. The power of the carriage spring in the movement of the carriage fromv right to left is effective to overcome the power of the spring 62 and to move the contact device 57 to the left with 'the carriage a distance corresponding to a letter space movement of the carriage. This movement of the contact device 57 is effective to move the link 69 longitudinally, transmitting a downward movement to the link 7 3, through. the inter.- posed bell crank 71. The downward movement of the link 7 3 is effective to move the controlling member 51-52 from the position shown in Fig. 1 to that indicated in Fig. 2, thus throwing the pins 41 on the set of actuating links out of the engaging notches-39 and into the slots 38. A depres-- sion of a finger key at this. time merely results in depressing the associated key lever without transmitting movement to the printinginstrumentalities, thepin 41 on the associated link playing freely in the .slot 38. The key lever moving down independently of the associated type bar 46 and its actuatin connections 45, 42 and 40 will move with a ghtne'ss of touch which will at once warn the operator that the parts are disconnected and that the type bars cannot be operated.

I preferably employ a fixed stop; rod 91 covered with a cushion 92 against which the disconnected key levers are adapted to strike to limit ,their downward movements at about the termination of the lost :motion between. the key levers and the links 40 .as shown in Fig. 2.

tends transversely beneaththe key levers This stop rod e'x-.

held against further movement by the cooperation of the contact devices or stops 56 and 57. The stops can move no farther to the left and they hold the carriage in the position at which it has been arrested. Should the operator desire to reestablish connection between the finger keys and the printing instrumentalities, to insert a hyphen or complete a word, it is merely necessary to depress the finger piece 65, thus moving the contact device 57 out of the path of the stops 56. This clearance of the stops enables the spring 62 to move the stop or contact device 57 to the right, thus enabling the parts to be restored to the normal positions indicated in- Fig. 1, and reestablishing operative connection between the finger keys and the printing instrumentalities. The operator is then at liberty to continue the writ ing.

I It will be understood that in the use of my invention no shock or strain is exerted on line lock mechanism resisting the pressure exerted by the operator on the finger keys.

A final contact devlce '7 5, a margin stop 7 6 and a'final margin stop 77 are constructed and arranged in the same manner as in the No. 10 Remington machine, and cooperate with the contact device 57 in the same manner as the corresponding parts in said machine. Further description of the operation of these parts is deemed unnecessary for the purpose of my present invention.

It will be understood that an adjustment. of the stop 56 regulates the length of a line; I

that the intermediate actuating connections between the finger keys and type bars are such that they may be automatically broken or rendered inefiective to transmit movement from the finger keys to the type bars; that in the present instance the eflectiv'e connection is broken by the production of a lost motion connection due to the pins ll working in the slots 38, and that the finger piece" 65 and the parts controlled thereby constitute hand controlled means operable at will to reestablish operative connection between the finger keys and printing instrumentalities,and thereby render the finger keys operative on the printing instrumentalities.
