naft r des ribed nd. particularly poin ed 0 tmjhe dam invention is shown herein as embodied in a N0. 11 Remington typewriting'machine but aswill be apparent the invention may readily be adapted'in whole or in part to other styles of writing machines.

. In the accompanying drawin s, Figure 1 is a vertical sectional view of a. 11 ypewriting machine embodying my invention, parts of the machine being omitted, the section beingtaken on planes indicated by the broken dot-ted line in Fig. 3. Fig. 2 is a fragmentary plan View showing the upper rear portion of said machine. Fig. 3-is a vertical transverse sectional view taken on planes indicated by the'hroken dotted line 3 in F ig. 1 and looking in the direction of t e arrows at said line. Fig. 4 is a fragmentary vertical. sectional view of the stop magazine, the stop controlling devices and asso'ciated parts, the view corresponding with Fi 1 but omitting parts shown in said sitions, and still other parts being broken away for clearness of illustration. Fig. is afront elevation, artly in section,of the stop magazine detac ed, some of the associated parts also being shown. Fig. 6 is a vertical sectionalview, taken on the plane indicated by the. dotted line rz of Fig. 1 and looking inthe direction of the arrows at.

connectedwith it a shiftable 1.231116 8' in which is mounted a rotary platen 9. The machine is of the front-strike'style, and the printing instrumentalities (not shown) are of the kind common to the No. 11 Remington machine and cooperate with the front face of said platen 9. Fixed to the truck 7 is an arm "10 connected by a hand 11 with a carriage motor or spring drum 12 which constantly urges leftward the platen carriage,

. figure, s owing other parts in different posaid carriage comprising the truck 7 and the platen frame 8 on which the platen is supported. The letter spacing movements of the carriage are controlled by the usual or other suit-able escapement-devices, said devices comprising a feed rack 13 mounted on arms 14 pivoted at 15 to ears 16 of brackets 17, said brackets, as shown in Fig. 2, being secured by screws 18 to the rear part of the truck 7. The rack 13 is normally maintained in spring pressed engagement with a feed pinion 19 secured to the forward end of a shaft 20 with which are operatively connected escapement wheels, not shown, said wheels cooperating with an escapement dog, as is well understood, the dog aforesaid being actuated from the usual printing keys and the space bar of the machine.

Cooperative with the key-set t'abulator stops to be hereinafter described are denominational stops 21, said stops being at the forward upper ends of stop levers 22, the stops 21 and levers 22 being preferably integral. The levers 22-are ulcrumed at 23 to a frame 24 detachably secured at 25 to the top plate 3, the lower end of said frame 24 being locked to a bracket 26 fastened by screws 27 to the rear of the base 1 (Fig. 3). The lower ends of the levers 22 are con-, nected by links 28 with bell cranks 29 fulcrumed on a fixed bar 30 and provided with restoring springs 31. Said bell cranks are operative by vertically movable key stems 32, each provided at its top with a button or tabulator key 33. The bell cranks 29 preferably operate carriage releasing devices comprising a universal bar or bail 34 arranged behind the depending portions of the bell cranks 29 and bearing loosely on the rod or bar- 30. A link 35 connects the releasing bail 34 with a crank arm 36 fixed to a rock shaft 37 on which is also secured an angular member 38 provided with a pin 39 engaging in a slot 40 in the lower part 41 of the two-part link which further includes an upper part 42, the

parts

41 and 42 being adjustably connected by a turn buckle 43. The upper end of the two-part link is connected to a releasing lever 44, fulcrumed at 45 to an angular bracket 46 secured to the top plate, said releasing lever extending horizontally forward and being provided with a shoe or lifter 47 which underlies the feed rack 19 and is adapted at each tabulating operation to swing upward, due to the actuation received from the universal bar through the train of connections above described. Upward movement of the shoe 47 lifts the feed rack 13 out of mesh with the feed pinion 19, thereby freeing or releasing the carriage for a tabulating run.

The denominational stops 21 are adapted to cooperate with column stops 48 of which there are preferably provided a number corresponding with the greatest number of colu'mns for which 'the machine is adapted. The column stops are housed in a magazine or container 49, shown detached in Fig. 5, said magazine comprising a body portion 50 shaped like an inverted U and provided with a floor plate 51. Within the body 50 the column stops are mounted on a rod or bar 52 (Fig. 4) which extends through said body 50 and issecured at its inner end in an extension or barrel 53 which contains a spring operative on a follower that constantly presses the column stops leftward along the supporting rod 52, the free end of said rod being rovided with a spring plug 54, which yiel s to permit the ejection or retraction of the column stops one at a time. The spring pressed follower and the internal construction of the magazine are not herein disclosed as they substantially correspond with the construction shown in the patent of Herbert H. Steele, No. 1,037,076, granted August 27, 1912, and are not claimed per se by me, being the invention of the said Steele. The head of the magazine, however, differs in detail from that disclosed in the application of Steele aforesaid and will be more particularly described. Said head, preferably a casting, is designated by the numeral 55, andis provided with lateral cars 56 which embrace the sides of the body 50 and are secured thereto by screws 57. The head is grooved vertically to provide tracks or guide ways for the slidable ejecting and retracting devices hereinafter described, and forward of the grooved track-ways is provided wit-h a circular hole or depression 58 closed at the top, a corresponding depression 59 closed at the bottom being provided in the head at the.

rear of the track-ways (Fig. 4). The magazine, comprising the body 50, barrel 53 and head 55, is movably mounted on the frame of the machine so that it is adapted to yield transversely of the machine orin the direction of the carriage movement in both directions. It will be normally maintained in a central position by spring controlling means. In other words, the magazine is slidably mounted and is spring pressed.

Referring specifically to the mounting of the magazine, the body 50 is provided at its front side with two pairs of ears 60 and at its rear side with a single pair of ears 60.

Each pair of cars receives between its memlug receiving a bearing screw 65 on which is pivoted a small wheel or. roller 66 and is adapted to rotate in a vertical plane. To

support and cooperate 'with the

rollers

61 and 66 at the rear side there is provided an face of the bracket 67 being in the same plane as the. front of a slotted guide plate through which the denominational stops are projected. Theguide plate 67 is. provided withjopenslots 69 in which the rear rol v s 66 engage and bear, while therear roller 61 is adapted to bear againstthe front face of said plate 67. At the front side of the magazine a bearing plate 70 is provided,

said bearing plate being bentotl laterally from the vertical or upstanding portion 71 of a supporting bracket which further includes a foot portion 72 secured to the top plate 3 by screws 73. The plate 70, as appears in Fig. 3, is provided with a slot 74 in which engages the forward roller 66 but the forward roller 61 bears against'the rear vertical face of said guide plate. As appears from Figs. 3 and 5, a stud or pin 75 projects forward from the magazine body 50, while below it a stud 76 projects rearward from the guide plate 70. Embracing the studs are the upstanding parallel arms or..-port-ions 77 of a centering and restoring spring, the body 78 whereof is coiled around a supporting screw 79 secured to the plate 70. Thecons truction is such, it will be observed that-th'eflma azine, confined between the plates 7 O and 6 is capable of horizontal movement in the direction of the carriage movement, but is held from up and down movement by the cooperation of the rollers 66- with the

guide slots

69 and 71, while fore and aft horizontal movement is prevented by the engagement of the rollers 61 .with the vertical facesor walls of the plates 67 and 70. The spring arms 77 c9- operate with the studs 75 and 76 to maintain the magazine in a-central normalpositicn. If the magazine is pushed slightly :t-oward the left, the left-hand spring arm 77 will be flexed by the stud 75 and will operate when leftward pressure on the magazine is removed to restore the magazine while the right-hand arm 77 performs the same functions when the magazine is displaced toward the right. The result is that the magazine may yield slightly to vary the position of the entrance orslotway 80 (Fig. 5)- which is formed between the floor plate 51 and the beveled edge 55 of the head 55. This slot way 80 provides the opening or mouth through which the column stops are ejected from the magazine on to the stop bar and through which said column stops are retracted from the stop bar into the magazine when the stop bar is to be cleared. The result will be that if the ejected or retracted column stop should not be in exact register with the slot-way, which may happen because of inequalities in the constructio of the parts'or in the cutting of the stop bar teeth, the magazine will adjust itself to compensate for such inequalities or irregularities. The-top edge of eachstop 48 is beveled, as indicated at 81,50 :tha-tif. during retraction the bevel 81 contacts; with the floor plate 51, the magazine will-be forced slightly rightward until the'slot therein is in register with the stop wheeL On 5 the other hand, if the upper edge-ofthe slot 75 I should contact with the beveledjedge 55; the magazine will be forced toward the left to the necessary extent. I When ejected fromthe magazine, as hereinafter described, the column or tabulator 6 stops 48 are adapted to be received by and set on the stop receivin g elementor .stop bar 82, which is grooved to receive. stop receivmg notches 83 a letter space distance'apart, these notches being U-shaped and extending around three sides of the bar, the-fourth side of t-hebar forming a projection 84 .which is smooth and free from notches or depressions (Figs. 4 and 5). The stop bar 82- isqar ranged below the stop magazine and at its ends is' provided with pintles 85- and '86 which bear rotatively in'holesor depressions formed in blocks 87 secured' at 88. to'the brackets 17. The construction is'su'chft-hat the stop bar is confined between the blocks and is thus held from endwise movement I but may rotate'on its pintles toa limited extent. Manual means are provided for giving this rotary movement or adjustment to the stop bar, saidmeans comprising a crank arm 89. (Figs.f2,-3 and 4) 'hav ng a. hub 90 rivetedat 9.1fto the pintle 86 between the block 87 and the body of the stop bar. its other endfthe crank arm 89 is provided with a finger piece or handle 92.

To limit the movement of the stop bar, devices are provided tocooperate with the crank arm 89 comprising a bracket 93 screwed to the underside of the "right-hand bracket 17 and having upturned cars 94 di- 11o verging upwardly at opposite sides of the pintle 86, the rear ear terminating in an extension or tab 95 and the front ear in an extension .or tab 96. The

extensions

95 and 96 are horizontally disposed buthhave in clined faces, which may be marked with suitable indicating marks as for example the rear tab may be marked Tab for tabulator, and the front tab may be marked Set and Clear. \Vhen the handle 92120 is pushed rearward, as in Figs. 1 and 2, the crank arm 89 will co-actwith the tab 95, indicatin that the stop bar is adjusted to position t e stops for tabulating' operations, while when the crank arm -is pulled forward until it engages with the edge of the tab 96, as in Fig. 4, it"indicates that the stop bar is arranged to permit of the set-- ting on or removal of the column stops. Those portions of the notches 83 which are 1.30

uppermost at this time are beveled as indicated at 83 to provide a flaring mouth to receive column stops as they move downward from the magazine. A detent spring device 97 is secured to the right-hand block 87 -(Fig. 2) and cooperates with flat faces .98 on the pintle 86 to maintain the stop bar stops 48, when the stops are ejected or moved greater security against displacement.

downward on and set on the stop bar. As in the Steele application aforesaid, a spring pressed locking rod 99 may be provided on the stop bar to hold the set stops thereon. When the stops have been ejected by devices hereinafter described, the handle or key 92 is pushed rearward, turning the stop bar and column stop set thereon to the posi tion shown in Fig. 1 Where the set stops are adapted to cooperate with the projected denomination stops. In prior construct-ions where the magazine has been above the stop bar and the cooperating or denominational stops have been at the rear of the stop bar the ejected stops were liable to be bent or broken as a result of the impact against the cooperating stop, the break taking place at the upper rear portion of the stop where its horizontal branch and its rear vertical branch join, the lower end oftherear vertical branch being without any anchorage or connection to the body of the stop. By the present construction it will be observed, the stop, after it has been ejected and set, is turned so that the face that co-acts with the denominational stop is joined or connected at. both its top and at its bottomwith portions of the stop which fit into grooves on the stop bar, thus providing a much stronger stop and one which is reinforced at both top and bottom against bending or breakage.

In order to eject and retract the column stops, devices are provided which are'controlled by a single key or finger piece. Said devices comprise an ejector, setter or slide block 100 and a retractor or slide block 101. The blocks 100 and 101 are seated in and reciprocate in the grooved ways in the head 55, as has been described. Normally the bottom of the ejector overlies the left-hand column stop on the magazine and will when operated engage said stop and force it downward. The ejecting and retracting devices or blocks are interseated one in the other, as indicated at 102 (Fig. 2),-thereby providing Each device is provided with a separate restoring spring. The spring 103 for the ejector 100 is seated in the depression 59 and at its upper end engages a pin 104 projecting laterally from said ejector, said pin being adapted to play in a slot 105. A plate 106, secir ed by a screw 107 to the'top of the head 55 limits upward movement of the ejector.

The spring 108 of the retractor is seated.

in the depression 58 in the head 55 and bears at its lower end against a pin 109 projecting laterally from the block 101 and playing in a slot 110 in the head. A screw pin or stop 111 projects from the ri ht-hand face of the block 101 near its top fFigs. 2 and 5) and engages in the bottom 0 a groove 112 in the head to" limit downward movement of the retractor 101. Said retractor is provided with a downward extension 113 terminating in a head or retracting device proper 114 which normally is lower than the bottom of the set column stops and underlies their path forward of the stop bar. The springs 103 and 108 normally maintain their respective slide blocks or devices against their limiting stops, such normal position of the parts being shown in Fig. '1.

The tram of devices for actuating the stop ejector and the stop retractor comprises a slidable element or actuator designated as a whole by the numeral .115. Said actuator is arranged at'the left of the ejector and retractor andextends downward at the rear of the top plate. At itsupper end it has a forwardly projecting portion or fin er 116 which is formed at its top edge wit a depression 117, engaging which is the head or body portion of the screw pin 111 which projects laterally leftward from the device 101, as shown in Fig. 5. The lower edge of the finger 116 is provided with a notch or depression 118 with which normally engages a screw pin 119 on the ejector 100. Behind the finger 116 the actuator 115 is enlarged to provide a plate-like head which is formed with a vertical guide slot 120, said guide slot cooperating with a headed screw 121 secured to an ear 67 turned upward from the left-hand end of the horizontal portion of the bearing plate or bracket 67 (Figs. 4 and 5). The actuator is thus adapted to move freely up and down but is held against lateral displacement and maintained in position to cooperate with the screws or

devices

111 and 119. Furthermore by reason of the sliding connection between the actuator and the screw pins 111 and 119, the yielding movements of the stop magazine 49 are not obstructed since the actuator may either move slightly laterally behind the head of the screw 121 participating in such yielding movements or else the screw pins will slide transversely of the actuator and over the

depressions

117 and 118 therein. The lower end of the actuator 115 terminates in a laterally bent car 122 (Fig. 3) which is pivotally connected at 123 with a lever 12 1 fulcrumed between its ends at 125 on an car 26* projecting ward from the bracket 26'. 'The right-ha which engages with a headed pin 127 on'a crank arm 128. Said crankarm, as shown in Fig. l, is provided with a hub v129 secured by a set screw 130 to the rear end of the horizontall disposed and forwardly extending rock shaft-131, said rock shaft atits rear end portion bearing in the right-hand rear post-2 and at its'forward end in a flange of the right-hand front post 2. collar 132 is secured to; the shaft behind said flange, preventing forward displacement of the rock shaft, while rearward displacement thereof is prevented by the hub 133 of a crank arm 134, said crank arm being secured in place by a set screw 135 The crank arm 134 at its upper end is provided with a handle, finger piece or key 136 for rocking the rock shaft in either direction and moving the actuator 115 up or down by the train of connections above described. On the rock shaft and confined between the front corner post and the hub 133 is an indicating plate 137, said plate being secured by a screw 138 to the corner post and being provided atits upper end with. indicating marks such as the word Clear and anarrow at the left of the crank arm 134, and the word Set and an arrow at the right of said crank arm. The crank arm 134 15 normally upright and disposed midway of the indicating plate, being maintained in this position. by a spring 139- which surrounds the fulcrum or screw 125 and has parallel arms which embrace a pin 140 onthe lever 124 and a pin 141 on the car 26. Said spring 139 operates both as a centering and restoring spring. Normally it coeperates with the pins 140-and'141, as shown in Fig. 3', to maintain the crank arm 134vertical and the connected parts in the relationships shown. If the crank arm is moved to the left the upper branch of the spring 139 will be flexed and will later operate to restore the parts to normal position, while the lower branch of said spring will be flexed when the crank arm is moved from normal position toward'the right.

Preferably full stroke devices are provided in association with the stop setting and-clearing key 136, said devices corn-prising 8. depending pawl or detent 142 pivoted at the rear face of the crank arm 134 and provided with a spring 143 w ich tends to maintain said pawlvertical. e pawl cooperates with sets of oppositely disposed teeth 144 and 145 formed in the top of a plate 146 secured at the front of the indicatmg plate 137. When the key 136 is pushed leftward the pawl 142 engages the teeth 144 and prevents return movement of the key until its full stroke has been completed andit has been moved leftward past the teeth of the lee 'ver. 124 is formed with an elongated slot 126 144, Tho' sreverse iwperation takes place when the key; 136 is 'pushed to the" right and the pawl 142;.eng'ageswiththe teeth 145. Following up the train f devices coritrolled by the key 136 it will be observed that whom-the key-is actuated toward the right, that is, to set stopsas indicated by raised, acting 0 the lever 124 to depress its inner end and lowerthe actuator 115. As the actuator is lowered the finger 116, acting on the-pin 119,- will force the ejector -10!) downward,- causing said ejector to en- 'the plate 137, the crank arm 128 will be" gage the top of the left'rhan'd column stop 48 in. the magazine, forcing said stop past the spring lug 54 and down on to the stop bar 82- course as' a preliminary it will be understood that the handle 92 has been pulled fotw'ard,.tu'rning the stop bar to stop receiving position and that the carriage has been spaced along until the appropriate notch or seat on the stxiggebar is in register with the entrance 5!) to t lowin the ejection, the key 136- is released and t parts will be restored to normal position by the springs 103' and 139. Thereafter it is only necessary to space the carriage to a position where it is desired to eject the next eollmm'stop and set it on .the stop bar, whereupon the key 136 is again magazine. Folactuated toward the left and the operations above outlined ar'e' repeated. It Wlll be understood that during stop-ejecting operations the stop retractbr 1101 willnotbe affected. In stop retracting operations the key 136 isactuated toward the left,'lowcring the crank arm 128 and causin' itto lift the inner arm of the lever 124, sai lever in turn lifting the actuator 115,- which'acts against the screw 1121, causing it to lift the retractor. 10 1, the head 114 thereof engaging with the overlying column stop 82 and forcing said column stop off the stopbar and' through the slot or mouth 80' into the stop magazine.

During ejecting and retracting operations,

the stop in moving from the container element to the stop receiving element and vice .versa', may operate to elfect' a relative movement between: said elements to bring the container mouth and stop notches into proper registen ,In order to facilitate stop retracting operations, means are provided preferably under' the control of the key 136 for automatically releasing the carriage from the controlof its escapement devices so that it may run freely leftward under the impulse of the carriage motor, other means being provided under the control of said hey for automatically projecting a special stop to cor operate with the column stops to arrest them -in turn under and in register with the slot 80 in the magazine. By employing the automatic means afioresaid and now to be described in detail, it is only necessary, in

order to clear the stop bar of column stops, successively to actuate the ke the left or in stop retracting direction a sufficient number of times, the number, of course, depending on the number of .column stops set on the stop bar. For automatically releasing thecarriage from the key 136 it is only necessary to provide a connection between the lever 124 and the two-

part link

41, 42. Said connection comprises a link 147 (Figs. 1 and 3) which is pivotally connected at its upper end at 148 to an ear 43 on the turn buckle 43 which connects the

parts

41 and 42. The lower end of the link 147 is rovided with a slot 149 which is engaged y. a headed pin 150 on the right-hand arm of the lever 124. The construction is such that when the key 136 is moved rightward in stop setting operations, the righthand arm of the lever 124 will be swung upward, lifting the pin 150, said pin traversing the slot 149 without actuating the link 147. When, however, the key 136 is actuated toward the left from normal position to clear the stops, the crank arm 128 will operate to swing the right arm of the lever 124 downward, causing the pin 150 to pull down the link 147 which in turn will actuate'the link 41 and raise the shoe 47, said shoe operating to raise the feed rack 13 from the pinion 19, thereby releasing the carriage. It will be understood further that when, actuated by the link 147 and key '136, the two-

part link

41, 42 is pulled down, the slot 40 at the lower end of the part 41 will move downward over the pin 39 andwill not affect the member 38 nor any of the other connections up to and including the universal releasing bail or bar 34. On the other hand, when the carriage is released by the operation of said bail 34 acting through the member 38 and

link

41, 42, said link, as it moves downward, will carry with it the link 147, which, however, will move idly, the slot 149 moving down along the pin 150 without affecting the lever 124 and connected parts.

The special arresting stop heretofore referred to, which is automatically operated from the key 136, is designated as 151. As

appears in Figs. 1, 2, 4 and 6, said stop is in the form of a rectangular block which is slidably mounted in a groove or depression 152 cut or formed in the top of the head of the tabulator supporting frame 24 and extending from front to rear at the left-hand side of said head. The left-hand end of the horizontal portion of the bracket or device 67 overlies the stop 151 and prevents acci dental upward displacement thereof. The right-hand vertical face of the forward end portion of the stop 151, which is its working face, overlies and is in the same vertical plane as the working face of the decimal stop of the set of denominational stops 21.

136 toward At its rear end the stop 151 is provided with an upstanding lug 151 which carries a leftwardly extending pin or stud 153, said pin engaging in a slot 154 at the rear of the head of the actuator 115. Said slot comprises a long, vertical portion or dwell, an inclined or cam portion connected with the lower end of said dwell, and a short, vertical portion or dwell connected with the lower end of the cam portiom Normally the stud 153 engages about midway of the long dwell in the slot 154 as shown in Fig. 1, the result being that when the actuator is pulled down for the purpose of ejecting column stops, the special stop 151 will not be affected. During the first part of the stop retracting operation the actuator 115 moves upward and the lower portion of the long dwell will move up past the stud 153 so that the special stop 151 will not be affected until the bottom of said dwell is reached. During thisfirstv portion of the upward movement of the actuator it will operate to raise from the stop bar 82 that one of the column stops 48 which is in posi tion for retraction, and when the cam porthe column stop will continue to rise and be retracted within the magazine while simul taneously the special, stop 151 will be forced forward by the cam slot 154, the forward movement continuing until the dwell in the slot 154 below the cam portion is reached. During this camming operation, fore and aft displacement of the head of the actuator 115 will be prevented by the screw 121 acting againstthe rear edge of the slot 120. By this camming operation, the special stop 161 is projected into the path of the column stops 48 that remain on the stop bar 82. The parts are proportioned and adjusted so that the release of the carriage through the lifting of the feed rack 13 will begin as the special stop enters the field of the column stops, the result being that when the carriageis automatically released by the action of the link 147 on the

link

41, 42, the special stop 151 will have been projected forward into operative position. Thus it will be seen that a clearing or leftward actuation of the key 136 operates to lift or retract a column stop 48, to project the special stop 151, and to release the carriage, enabling the next column stop 48 to be brought into contactive engagement with the stop 151, thereby arresting the carriage. When the key 136 is released and restored to operative position the special stop 151 will be retracted to normal position, disengaging from the co-acting column stop 48 which will be left underlying and in register with the mouth 80 of the i to beginning 'Fi 4 position tofiir imam sto magazine. A secondleftward actuation of the key 136 will cause the retracting head 114 to lift the last mentioned column stop from the stop bar and retract it into the magazine while concurrently the special stop 151 will be projected forward to the and 'the carriage released ing the next column stop on the'stop bar into co-active engagement ,with said stop 151; and so on. It will be apparent that it is only necessary in order to entirely clear the stop bar of column stops to actuate the key 136 toward the left a sufiicient number of times, thus preparing the the reception of a differently arranged or adjusted series of column stops. Owing to the fact that the stop bar 82 is rotatable by hand to two positions, there is the possibility that the operator will neglect, after having set the settable column stops on said stop bar, to turn the bar back from the Fig. 4 to the Fig. '1 position, prior tabulating operations. On the other hand, there is also the possibility that the operator might neglect or forget to turn the stop bar from normal to abnormal position prior to beginning -a stop retracting or stop set-ting operation. In order to prevent I such possible faulty operations of the mechanism, devices are provided in the nature of checks or preventive means, which de vices are automatically controlled from the stop bar 82 itself. The checking devices comprise means for locking the denominat-ional stopgagainst operation when the stop bar 82 is in the abnormal or and also for locking the actuator against movement when the stop bar 82 is in the normal or Fig. 1 position, the sets of checking or lockin devices operating in alterna-' tion. The c ecking devices aforesaid are illustrated in Figs. 1 to 4 and 7 and comprise a lever 155 cured in a hole 15 tapped into the rear end of the bracket portion 71.

ward and terminates in a rearwardly bent engaging portion or which normally is disposed between two; locking devices or studs 159 projecting left- 1 ward from the head of the actuator 115.?

Forward of its fulcrum the lever 155 is provided with an open-mouth slot 160 which is 3 engaged by a pin or stud 161 projecting laterally rightward from the end of an arm or lever 162, said arm inclining forward and upward and being pivoted at 163 on the bracket portion 71. The rear end portion of the arm 162 which carries the stud 161 is off-setto the left so as to overlie the slotted portion of the lever 155, said lever being confined between the off-set portion of the arm 162 and the face of the bracket portion 71. A leaf spring 164 fixed to the arm 162 cooperates with a stud 165 on the stop bar for is adapted Fig. 4 position; 1

ivoted on a screw 156 se- The main arm'. of said lever normally extendsstraight uplocking device 158;

bracket ion 71 to maintain the locking device 1 8 normally in operative osltion between the studs 159. Rearwar movement of the lever 155 .and upward movement of the lever 162 are limited by the engagement of the lever 155 with the lower stud 169. The spring 164 constantly tends to maintain the parts in the Fig.- 1 position and operates to restore them to normal position after they have been actuated as presently to be described. The stud 161 projects rightward through a slot 166 in the bracket portion 71, said slot affording play for the stud, which engages at its inner end in a slot 167 formed in a crank arm 168 on a rock shaft 169, extending transversely of the denominational levers 22. Said rock shaft is reduced at its ends and the lefthand reduced end thereof bears in a hole 170 formed in the bracket portion 71 while the right-hand end of said rock shaft 169 bears in an angular bracket 171 secured b screws 172 to the top plate 3. The rock shaft 169 is provided with a downwardl and rearwardly inclined fin or rib 173 whic normally registers with a series of notches 17 1 cut in the forward edges of the denominational levers 22, said notches form ing in efiect a groove extending transversely of the gang or set of levers 22. The train of devices comprising the

levers

162 and 155 and the rock shaft 169 are adapted to be automatically actuated by the rounded end of the projection 84 of the stop bar 82 which to act on a rounded projection or nose 162 on the lever 162.

With'the locking devices in normal position as shown in Fig. 1 the movement of the denominational lovers will not be interfered wit-h by the locking rib 173, since the notches 174 in register therewith are deep enough to permit complete forward 'movements of said denominational levers. The actuator 115, however, will be locked at this time against actuation for if an ejecting operation be attempted, the upper stud 159 will contact with the upper end of the locking device 158; while similarly an upward or retracting operationof said actuator 115 will be prevented by the lower stud 159 en'- gaging with the under edge of the locking device 158. When, however, the finger piece or key 92 is pulled forward,. turning the stop bar 82 from the normal position to the abnormal position shown in Fig.4, the extension 84, acting against the nose 162, will overcome the spring 164 and swing the arm 162 downward, causing the stud 161 to swing the lever 155 forward and turning the rock shaft 169 on its axis. The forward movement of the lever 155 carries the locking device 158 out of the path of the studs 159, thereby releasing or unlockin the actuator 115 so that it may be operated from the key 136. The rotary turning movement heretofore described,

or locking device 173 aforesaid of the rock shaft 169 concurrently swings the rib 173 to a horizontal position where it is out ofregister with the notches 174 and is close to the forward edges of the levers 22. Consequently, if it be attempted to actuate one of the tabulator' keys 33, while the stop bar 82 is in abnormal position, the parts" will be locked, since very slight motion will bring the actuated lever 22 into engagement with the rib 173 which will prevent operation. The locking device 158 will remain out of operation and the rib will remain in operative positlon so lon as the stop bar 82 is in stop receiving position; but when the de sired number of column stops have been adjusted on said stop bar and the same is turned back to normal position, the extension 84 will release the nose 162 and concurrentl the spring 164, will swing back the locking device 158 to operative position and will lower the locking rib 173 to inoperative position in register with the notches 174, thus locking the actuator 115 against operation and freein the tabulating mechanism so that it may% carriage in accordance with the adjustment of the column stops 48 set on the bar 82.

It is to beunderstood that parts of the invention as above described may be used without other parts, and also that various changes of construction, arrangement and mode of operation may be effected without departing from the spirit and scope of my present invention. there are shown modified means for controlling the rock shaft 131. In the Fig. 8 construction, instead of the lever 134 which is swingable in opposite directions from a central normal position, there is substituted a rocking frame or lever 175 which has a hub 176 secured by a screw 177 to the forward end of the rock shaft 131. The opposite arms of said lever 175 keys 178 and 179, the top of the left-hand key 178 being provided with an indicating device such as the word Clear, while the right-hand key 179 bears the word Set. By pressing the setting key 179'the shaft 131 is rocked toward the right and operates on the crank arm 128 as originally described to actuate the stop setting mechanism. On

'the other hand, an operation of the left-hand or clearing key 178 rocks the shaft 131 in the opposite direction and is effective, as to actuate the stop clearing mechanism.

It will be understood that by my present invention there is provided in tabulating mechanism for typewriting machines the combination of a carriage or traveling element, a stationary element, in the present instance the frame of the machine, and a self-adjusting stop container on one of said elements, in the present instance said selfe used for spacing the For example, in Fig. 8,

that a tabulator' stop and a stop container are combined with means for affording movement of said container through the instrumentality of said stop; that such movement takes place when the devices for ac-' tuating or retractinga tabulator stop are operated; that a relative movement between the container element and the stop receiv ing element is afforded by means acting throu h the tabulator stop in moving from one 0% said elements to the other, the result being that said elements may be brought into roper register or alinement; that the stop ar in the present instance underlies the container which has a horizontal movement lengthwise of said stop bar in two directions but is prevented from moving transversely of the stop ba'r either vertical or horizontal;
