shouldbc understood. that the devices of our invention may be applied to other styles of writing machines.

The frame of the machine comprises a base 1, corner posts 2 and a top plate 3. Type bars 4 are pivoted to hangers 5 to swing upwardly and rearwardly to strike against the front face of a platen 6. The type bars are segmentally arranged and each bar is connected to a pull link 7, the rear end of which is pivoted at 8 to an upright sub-lever 9 connected in the usual manner to an associated printing key (not shown). Fixed carriage rails 10 are 7 secured to yoke-like brackets 11 which are attached to the top plate of the machine. These fixed rails are grooved on oppositely disposed faces for cooperation -withantifriction balls 12 which are likewise received in oppositely disposed grooved faces in a rear carriage bar 13.

The carriage comprises the bar 13 and end plates or arms 14 provided with bearings to receive a platen shaft 15 on which the platen 6 is mounted. Arms 16 are pivoted to the endbarsof the carriage and are connected at their rear ends to afeed rack 1 7 which meshes with a feedpinion 18 secured to the forward end of a shaft 19 which turns in a bearing 20 secured to the top plate of the machine. The shaft 19 is operatively connected at its rear endto an escapement wheel 21 by the usual pawl and ratchet mechanism (not shown). The escapcment wheel cooperates with feed dogs 22 carried by a dog rocker 23 pivotedat 24 to a depending bracket 25 secured to the top plate of the machine. The dog rocker has a forwardly projecting arm 26 to which the upper end of a link 27 is connected, the lower end of said link being connected in the usual manner to the universal bar frame (not shown) so that each actuation of a printing key is cll'cctivc to actuate the dog rocker to afford a letter space movement of the carriage in the direction of the feed under the control of a s )ring drum 28 connected to the carriage l strap or band29. The rear cross bar of the carriage is' provided with rcarwzudly oxtonding bracket arms near each end thereof, said bracket arms being provided with l) l.1lIlZS for arock shaft or column stop rod}? This slop rod is slotted on opposite sides thoirof as indicaicd at 3; for

. cooperation with "bifurcated adiusiablmcol- Cir iy a

lCb

umn stops 33 which may be attached to the column stopv red at any point in the length thereo fu' The upper fixed rail 10 has a bracket 34 secured thereto by screws 35. Rearwardly projecting arms 36 project from the. bracket and are perforated to form hearing Openings for the rece tion of a short v rock shaft 37 to which a ta ulator stop 38 is secured or forms a part. A coiled spring 39 surrounds the shaft 37 and is secured at ne end"40 to the sto 38 and at its opposite 1d 41 to one of the bracket arms 36. The pressure of this spring is exerted to normally maintain the stop 38 out of the path of the stop portions 42 of the cooperating column stops 33 as shown-in Fig. 1. The stop 38 is provided with a tail piece 43 which extends, on the opposite side of the rockshaft fromthe stop 38 and is notched at 44 for 006 eration'withan actuating device 45. A nger 46 projects forwardly from the sto 38 and inthe normal osition thereof is a apted to bear upon the liracket '34 as shown in Fig. 1 to arrest the tabulator stop 38 in its normal position. The actuating device 45, as shown 1n Fig, 2, comprises a frame-like member with an opening in the center thereof through which the feed pinion 18 and bearing 20 extend, the upper end of the member 45 terminating in a, finger 47 which directly co-acts with the notch 44 in the tail-piece 43 of the tabulator stop. Each side arm of the member-45 is slotted at 48-for the reception of a headed pin 49 which is connected to a carriage releasing device 50. The lower stem-like member 51. of the device 45 is pivotally connected to the left-hand end of a lever 52 pivoted at 53 to a bracket 54 I which extends downwardly from the top late. The right-hand end portion of the ever 52 is provided with an upwardly extending fin er 55 which constitutes a stop that normaTly bears against the top plate of the machine to limit the movement ofthe lever and the parts connected thereto in one direction. The right-hand end of the lever post of the machine.

to a 52 is pivotally connectedat 56 to a depending link 57, the lower end of which is pivoted at 58 to a rearwardly extending arm 59 of a three-arm lever ivoted-at 60 to a bracket 61 secured to t e rear right-hand corner An upwardly extending arm 62 of said leveris pivoted at 63 to a forwardly extending actuating link or rod 64 which at its forward end extends through openings in the right-hand forward corner post and is provided with a finger piece or utton 65. A third or downwardly extending arm 66 of the three-arm'lever extends point below the printing keys of the machine, and the lower end of said lever arm" is provided with a laterally projecting abutment or locking pin 67. The construction is such that when the operator ushes the key 63*65 rearwardly the three-arm ever 5962--- 66 will be vibrated to pull down the link 57', rock the lever 52 and elevate the actuating device 45 to turn the tabulating stop 38 on its ivot into the path of the column stops 33.

1? release key 68 is connected to the forward end of the release key lever 69 pivoted at 70 to an arm 71 secured to the baseof the machine. The lever 69 extends rearwardly of its pivot and cooperates with an expansion spring 72 which bears at one 'end against the rearend of the key lever 69 and at its other end against the base of the Inachine in order to restore the release key lever 69 and the parts connected therewith to normal osition. A laterally projecting pin 73 pro ects from the key lever 69 and extends into a slot 74 formed in a sub-lever 75 pivoted at its forward end as at 76 to a laterally projecting stud77 which extends inwardly from the base of the machine. The rear end of this sub-lever is pivoted at 78 to an upwardly extending link 79 which extends through an opening in the baseof the machine and is connected at its upper end to the right-hand end of a carriage release lever. 80. The connection between the link' 79 and the lever 80 is effected by the upper end of said link passing freelyv through an opening formed in the lever,

nuts 81 being threaded onto the up .er end of the link 79 above the lever 80. coiled spring 82 surrounds the link 79 and bears at its'upper end against the Washer 83 which surrounds the link and bears against the bottom of the lever 80,- the lower end of the spging bearing against the base of .the mac he The pressure of this spring is exerted to force the right-hand end of the lever 80 upwardly and to cause the stop or projection 84 thereon to bear against the top late of the machine and thus maintain the ever 80 and the releasing device 50 connected thereto in their normal positions. The left-hand end of the lever 80 is pivoted at 85 to a de pending stem 86 formed on the releasing device. 50. The u er end portion of the releasing device is ifurcated as shown in Fig. 2 to straddle the shaft 19 and the bearing 20 thereof and is bent forward at the upper ends of the arms of the bifurcated portion as indicated at 87 in Figs. 1,3 and 5. These portions 87 constitute rack lifting shoes which extend beneath the feed rack of the machine and are adapted to cooperate therewith when the releasing device is elevated, to turn the feed rack around the pivots of the arms thereof in order to disenga e the latter from overlap the sub-lever 75 and to form a contact shoe 94 with which the'lower edge of the release lever 69 is adapted to cooperate. The laterally projecting locking pin 67 extends beneath the sub-lever. 75 and the locking latch and. supports the weighted end of said latch as indicated in Figs. 1 and 2. The contact face 95 at the lower edge of the sub-lever 75 with which the locking pin 67 cooperates is substantially in an arc of which the pivot-60 is a center so that the sub-lever 75 is normally locked against depression by the locking pin 67 but said pin is free to move when the key 65 is actuated from the osition shown in Fig. 1 to that indicated in igs. 3 and 4 where the locking pin registers with the slot 93. This movement of the thre"earm lever andlocking pin to the osition shown in Fig. 3 from the position s own in Fig. 1 is effective to elevate the rear end. of

the latch. by the cooperation of the pin 67 i with the cam edge 96 of the latch until the notched portion adjacent to the locking shoulder 91 is reached when the rear end of the latch 89 will drop to the engaging posi tion shown in Figs. 3 and 4. In this position the shoulder 91 engages the rear side of the locking pin and locks the three-arm lever and the parts connected therewith against movement.

It will be observed that the locking shoulder 91is substantially in an arc of which the pivot 88 is a center and that when the parts are in the locked positions, represented in Fig. 3, the locking pin 67, the pivot 88 and the pivot 76 are substantially in a straight line so that the. tendency of the three-arm lever 596266 and the parts connected therewith to move to the normal position is resisted by a dead center pull 'on the fixed pivot 76. On the other hand, when the parts are in the normal position shown in Fig. 1 a' depression of the releasekey 69 and the parts connected therewith is resisted by the lever 596266 effecting a dead center pull against its fixed pivot 60 so that the release key 68 and. the parts connected therewith are normally locked against operation and cannot be moved until the tabulator key 65is actuated. When the tabulator key is actuated, the tabulator stop 38 will be moved into c'o6perative relation with one of the col- .umn stops 33 and the parts will be locked in the operative position by the gravity latch 89.. The act of operating the tabulating mechanism is eflectirre to move the locking pin into register with the slot 93, thus automatically releasing the release key 68, the

' sub-lever 75 and the parts controlled. thereby so that the release key may at this time be depressed. The effect of depressing the release key is to depress the rear end of the ing device and allowing.thccarriage to be column stops is brought into contact with. the'tabulator stop 38. The first portion ot the depression of the release key lever 69 is effective to bring the lower edge thereof into contact with the shoe 94 on the locking latch and to turn said latch on its pivot 88 out of locking engagement with the lockingpin 67 as shown in Figs. 5 and 6. The locking pm will be freed from the latch at the full depression of the release key 68 and. will move 5 when released from the locking shoulder 91 into engagement with the contact wall 92 of the slot in the sub-lever as shown in Fig. 6, so that when the carriage release lever 68 is released the pin 67 cannot be again enlever is effective to resist the movement of the other lever, and that each of said levers is effective to lock the other against operation, and that an actuation of one lever is efiective to release the other.

The mechanism described assures the correct operation of the parts and assures the proper interpositioning of the stop before the carriage can be released.

In the operation of the devices, the tabulator key 65 is first pushed inwardly thus automatically releasing the carriage releasing mechanism from looking engagement and locking the projected tabulator stop 33in cooperative relation with one of the column stops; that is to say, in a position where the stop 38 is in the path of the column stops and iscoperative to co-act with one of them when the carriage is released. The release key 68 is then depressed, thereby releasing the carriage and affording a movement thereof until one of. the column steps is brought into engagement with the tabulator stop 38. When tabulator stop 38 will be automatically released from its locked position and the parts. will be restored to normal position when the release key will be automatically locked until the tabulating, key is again actuated.

From the foregoing description it will be understood that the locking of the stops in cooperative. relation is effected independently of and is not dependent upon pressure maintained upon the finger key of the re lease, and that the locking of the release is,

efl'ected independently of and is not dependout on pressure of the finger maintained on the key of thetabulator and that the release key cannot be actuated until the tabulator is actuated.

pressure on the release key 68 is released the For the purpose of our resent invention the character of the tabu ating mechanism employed is immaterial and from certain aspects of the invention some features of the invention may be employed without others.
