To all whom t may concern.'

Be it known that I, GEORGE A. SEIB, citiaen of the United States, and resident of Ilion, in the countyy of Herkimer and State of New York, have invented certain new and useful Improvements in Type-*Writing Machines, of whichthe following is a specication. Y

My invention relates, generally speaking, to typewriting machines, the invention being directed more particularly to tabulating mechanism embodied in such machines.

The objects of the invention will appear lfrom the` following descriptiointhe invention consisting in the features of construction, arrangements of parts and combinations of'devices to be hereinafter set forth and particularly .pointed out in the appended claims. Y i

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure .1 is a fragmentary side elevation with parts in section of one form of typewriting ma'- chine embodying my invention, only so much of the machine being shown as is necessary to arrive at an understanding of the invention. Fig. 21s a fragmentaryplan view of the same. Fig. 3 is a fragmentary ,detail side elevation of a portion of the structure, the view showing the parts as they appear when one of the column selecting keys is depressed and the carriage is released.V Fig. 41 is a fragmentary detail side view on an enlarged scale and partly in section fof one of the columnV selecting stops and some of the associated parts. Figs. 5 and 6 are'fragmentary detail perspective views of vpor- While I have shown my inventionl in the present instance embodied in a No. 11 Rem# ington machine it should be lunderstood that the invention may beembodied in various styles of typewriting machines.

The present case is a division of my application Serial No. 7 34,991', filed February 11th, 1913. v i

vThe frame fof the machine comprises a base l, corner posts 2 and a top plate'. A rectangular carriageA comprises end bars 4, a forward cross bar 5 and a rearcrossbar 6. The forward and rear cross bars are grooved to receive anti-friction balls orl rollers 7 'which vare likewisel received in fixed guide rails 8 secured to the top plate of the machine. A cylindrical vplaten 9 is supported byV thecarriage in the usual manner. Upwardly and rearwardly, swinging typebars 1.0 are adapted to strike against the front face of they platen. These type bars are pivoted at 11 to the usual type bar hangers and have a segmental arrangement. Each 'type bar is actuated from a printing key 12 through the usual train of connectionsV comprising links 141- and 15 and an intermediate sub-lever 16, which latter is pivoted on a hanger 17. Each of the links 1A is connected toa key lever 18 fulcrumed at itsrear end on a fulcrum plate 19. A returning spring 2() is connected at one end to a key lever and'at its opposite end to a supportingplate 21 secured to thev base l of the machine. A universal bar 22 extends beneath the key levers and is connected in the usual manner (not shown) with the dog rocker which carries a feed dog. This feed dog cooperates with a doubleescapement wheel 23'secured to an escapement wheel shaft 21 adapted to turn ina bearing 25 iXedto the top plate of the machine. The forward end of the es capement wheel shaft has a feed pinion 26 secured thereto. `A Vfeed rack 27 meshes with the feed pinion 26 and is carried by arms 28 pivoted by shouldered pivot screws 29 to upwardly extending lugs 30 which project from the rear cross bar 6 of the carriage. A leaf spring 81 is secured by screws 32 to the cross bar 6 of the carriage and bears at its'free enol on the top of the feed rack 27 to force thelatter into'mesh with the Vfeed pinion. The carriage is thus mounted fory movement from side to side of the `machine over the top plate, the carriage being propelled' fromu right to left by a spring rdrum 33 connected by a band 3A with an arm 35 secured to the carriage.Y 1t should be understood that the movement ofthe carriage Afrom right to left is resisted by the usual escapement mechanisln.

The parts Ythus far described constitute part of the ordinary equipment of the No. 11 Remington machine.

The tabulator mechanism in the present instance includes the vordinary denomina-` tional stop mechanism employed in the No. 11 Remington machine and which comprises a series of push rods 61 each provided at its forward end with a key 62. These rods eX- tend through guide openings in a depending member 63 secured to the base of the machine by screws Gal. The rear end of each push rod is pivotcd, as at 65, to an upwardly extending denominational stop lever G0. The levers G0 are pivoted at G7 in a tabulator frame G8 which is secured to the frame of the machine in the usual manner. The stop levers GG extend forwardly at their upper ends to provide denominational stops 69 which extend through guide openings in a guide comb or plate 70 secured to the tabulator frame. Each push rod G1 is returned to the normal position by a contractile spring 71 secured at one end to a sleeve 72 fastened to the associated 'push rod and at its opposite end to the member G3. A slotted universal releasing bar 73 receives in the slots thereof the push rods 61 and each rod has fixed thereon a sleeve 61"L to engage and actuate the bar. This universal bar is in the nature of an angle-iron which is secured by screws 74 to a cross bar 7 5 which is formed in one piece with upwardly extending arms 76 supported on a pivot rod 77. Each of the arms 7 0 is provided with a rearwardly off-set ear 78 which is pivotally connected with a rearwardly extending link 79. The rear end of each link 7 9 is pi'voted as at S0 to a depending` crank arm S1 fixed to a rock shaft S2 mounted at its ends in the base of the machine. Another depending crank arm S3 is fixed to the rock shaft and has one end of a contractile spring Sel connected thereto, the opposite end of said spring being connected to a depending pin S5 secured to the base of the machine. It should be understood that the arm S3, spring 84: and pin 85 are situated to one side of the series of key levers 1S. A crank arm SG is secured to the rock shaft 82 and extends downwardly and forwardly therefrom and then upwardly and rearwardly where pivotal connection is made, as at 87, with an upwardly extending` link 8S which in turn is pivoted at 89 to a carriage releasing de vice or lever 90. Thisreleasing device is pivoted at 91 to a bracket 92 secured to the top plate of the machine and a shoe 93 at one end of the lever or releasing device extends beneath thc feed rack 27 and is adapted to elevate the feed rack against the pressure of its spring 31 when a denominational key G2 is actuated. The carriage has rearwardly extending bracket arms 94; secured thereto by screws 95. The rear ends of these bracket arms are connected to a column stop bar 9G provided with teeth 97 on the upper and lower edges thereof. Column stops 9S are received in the interdental spaces between the teeth 97 to secure the column stops in the different positions to which they may be adjusted along the column stop bar. It will be understood that an actuation of a denominational key 62 is effective to project the corresponding denominational stop G9 into the path of the column stops 98. At the same time the universal bar 78 is moved rearwardly, thus effecting an actuation of the rock shaft 82 which controls the releasing device 90, thereby lifting the feed rack out of engagement with the feed pinion 20 to release the rack from control of its escapement mechanism. This denominational tabulating mechanism is the same, or essentially the same, as that embodied in the ilo. 11 Remington machine.

In the present instance I have provided column selecting mechanism which may be used in conjunction with the denominational tabulator mechanism hereinbefore described. Thus 1 have provided rearwardly extending bracket arms 99 which are secured by screws 10Q to a scale bar 101 of the carriage. IThe rear ends of these bracket arms 99 are apertured to receive the reduced ends of a pivot rod 102, which rod is fixedly secured to the bracket arms by screws 103. This pivot rod extends substantially throughout the length of the carriage and parallel with the axis of the platen and is provided with a series of teeth 10-1 which are on the under side only thereof. These teeth are spaced at letter space intervals throughout, or substantially throughout, the length of the pivot rod. A series of Column selecting stops, each of which is designated as a whole by the reference numeral 105, is pivotally mounted on the pivot rod 102. Each of these column selecting stops in the present instance comprises the lever which extends fore and aft of the machine and is provided at its forward end with a linger key 100. The rear end of the lever is provided with a bearing opening by which it may be received on the pivot rod. An off-set pin or contact portion 107 projects from the left-hand side of each lever for engagement with a coperativc stop 10S on the frame of the machine7 as will hereinafter more clearly appear. Each column selecting stop is provided with a spring-pressed latch 109 (see Fig. 4), the stem of which is adapted to move in a bearing opening 110 in the body portion of thc stop 105.- The lower end of the latch is bent at right angles to the stem to provide an engaging member 111 cooperative with the teeth 10i on the pivot rod 102. An expansion spring 112 surrounds the stem 109 of the latch and is received in an opening 113 in the body portion of the stop lever. The lower end of the spring 112 bears against the bottom wall of this opening and the upper end of the spring bears against a head or finger piece 1111 which is connected to the stem of the latch by a threaded connection 115. The power of the spring 112 is exerted against the latch to normally maintain it in engagement with the teeth 10st. The power of this spring is also to against movement from the normal position and to return `the stop lever to such normal position when the stop lever is turned on the pivot rod 102. In order to facilitate such return movementwithout unduly increasing the size of the spring 112 l prefer to` employ an auxiliary spring returning means which is clearly illustrated in Fig. 4. Thus the rear side of the pivot rod 102 vis providedwith a recessedy or flattened face 116 against which a spring-pressed plunger 117, also provided with a flat contact face, is adapted to engage. This plunger is received in an opening 118 formed in the body portion of the stop lever, and a coiled expansion spring 119 surrounds a kguide pin or stem 120 which projects `Vfrom the head 117 and works in a central opening 121 a screw 122l received in a tapped `portion of the opening 118. This screw may bevprovided with a nick 123 for a screw driver or suitable tool by which the screw may be threaded into or withdrawn from the tapped opening in which it is received. .The 'spring 119 bears at one end against the screw 122 and at its opposite end against the head 117 of the plunger so as to force the plunger'into contact with the iattened .portion116 of the pivot rod,.thus exerting a forceto retain the associated stop lever 105 in its normal position and to return it to such normal position when pressure on the depressed linger key of such stop lever is removed. It will be understood, therefore, that the spring 119 augments the action of the spring 112 which is likewise effective for the same purpose.

Tt will -beseen that each stop lever 105 may be turned on its Ypivot rod from they normal position shown in full linesin Fig. 2 rearwardly7 to the dotted line position represented in Fig. 2; that when the Stop lever is turned to the dotted line position the key 106 which is carried thereby may be brought into Contact `with a lwork sheet A in the v machine and that the left-hand edge of the key may be brought into register with an indicatingl mark, such as a line 124, which divides two adjacent vertical columns a, c, CZ, `e` and Vfon the work sheet; that this same turning movement of the column selecting stop from the full to the dotted line position represented in `Fig.2 is effective to disengage the latch 109 fromthe pivot rod and uto move the said latch and the plunger 117 to such positions relatively to the pivot rod that they no longer tend to return the stop to normal position around the pivot rod; vand that when the stop is so positioned the latch is maintained disengaged from the teeth 104 so that astop at this time isfree to be adjusted to the desired position along the pivot rod 102.` When, however, theV stop is again movedfrom the -dotted line position shown in Fig. 2 to thewfull line position of this same stop, the latch 109 will again be brought intoengagement with the teeth 104 on the pivot rod to secure the stop against movement along the rod and in the position to which it has been adjusted lon-` gitudinally of the rod. Nevertheless, at this time the stop 105, or any of them, maintained in the normal position, is free to be depressed byits fingerkey, as represented in Fig. 3, without disengaging the spring pressed latch from the teeth 104.

A universal release bail or bar 125 extends throughout the length of the carriage beneath the stop levers 105 and in the path of movement of the latter when they are depressed fromthe normal position. This bar` is iiattened and turned rearwardly atv the ends thereof, as indicated at 126, the rearwardly extending portions of the bar eX- tending beneathk the usual carriage release keys 127 to which the release bar is fiXedly securedby screws 128. Each release key is formed as a part of a release lever 127a which is pivoted on ashouldered screw 128l and is held in place thereon by a nut. The

forward portion of each lever 127 a is. slotted as at 129 to receive a shouldered screw '129% so as to enable the release levers 127a tomove independently of the screws 129s. A nut is received on the outer end of each shouldered screw 1292*. The rear end of each release lever extends beneath the feed rack 27 so that a depression of either release key 127 or the universal releasebar 125 is effective to lift the rack out of engagement with the feed pinion 26, as shown in Fig. 3, thus freeing the carriage for movement from right to left under `the power of its' into the path of engaging hooks on the key' levers.18 to prevent an actuation of-said key levers. This will be better understood from an inspection of Figs. 2, 5 and 6 from which it will be observed that a slide or plate 130 is provided with slots 131 which receive headed screws 132 by` .which the plate is. supported to receive a limited longitudinal movement, the screws 132 being received at' their threaded ends in tapped openings in the under side of the forward fixed carriage rail 8. A three-arm lever 133 is pivoted 4at 134 to the slide 130, one arm of this lever-being connected to one end of Veo 5 139 in the slide 130. The third arm of the lever 133 is bent forwardly at the end thereof to form a contact linger 140 which eX- tends into the path of a depending arm on the stop 108. It will be seen therefore that a movement of the stop 108 from right to left is effective to transmit a bodily movement to the lever 133 and slide 130 on which it is mounted, this movement of the parts being effected against the pull of the spring 135. The left-hand end of the slide 130 is bent downwardly to form a depending `finger 141 which is received in a cut-out or slot 142 in an angular lever 143. This lever is pivoted at 144 and has its opposite arm pivotally connected at 145 to a depending link 146 which in turn is pivoted at its lower end, as at 147 (Fig. 1) to a universal locking bar 148. This bar has a flange 149 which is adapted to be received beneath the hooklike engaging members 150 on the key levers 18. The locking bar is pivoted to the base of the machine on pivots 151 so that'when the stop 108 is moved to the left motion is transmitted to the locking bar 148 through the intermediate connections 146, 143, 130 and 133 to move the locking bar to the operative position where it prevents an effective depression or printing movement of any of the key levers. It will be understood, therefore, that when one of the column selecting keys 10G is depressed this results in releasing the carriage, and the carriage will move tothe left under the power of its spring drum until the contact pin 107 on the depressed stop engages the stop 108 on the frame of the machine. The stop 108 will be moved a short distance to the left before the carriage is arrested, thus actuating the line lock mechanism to prevent an operation of the printing keys until the depressed column selecting key has been released and the parts restored to normal position. The release of pressure on the column selecting key enables the actuated column selecting stop to return to normal position, thereby releasing the stop 108 when the spring 135 will return the stop 108 to normal position and will release the line lock mechanism controlled thereby. It will be seen, therefore, that a printing operation cannot be effected until the column selecting key and the parts controlled by a depression thereof have all been restored to normal position.

From an inspection of Fig. 2 it will be observed that each of the column selecting keys has indices inscribed thereon which correspond to the headings of the corresponding column which it is operative to select. For example, there are shown in the present instance, six columns a, b, c, ci, e and f on the blank A and there are six column selecting stops and keys, each key head bearing an inscription which corresponds to the heading at the top of the particular column which the key in question is operative to select. Thus the first column having the headingV Total, the iii-st key counting from the left has a corresponding designation thereon. By these means it is unnecessary for the operator to bear in mind the location of the particular column in which an item is to appear. If, for example, the first item to be written in a line is to appear under the heading Parts, it is merely necessary for the operator to actuate the key bearing the corresponding designation Parts in order to select the proper column.

The adjustment of the column selecting stops longitudinally of the pivot rod 102 enables the operator to readily adjust said stops according to the location of the columns where the items are to appear and by swinging a column selecting stop rearwardly to the dotted line position and bringing about a registration between the left hand edge of the key and the left-hand dividing line for the corresponding column, the stop can be accurately set according to the sheet in the machine. After the column selecting stops have been adjusted in the manner described the column stops 98 will receive an adjustment in accordance with the adjustment of the column selecting stops. lVhen the different stops have been adjusted as stated they will appear as shown, for example, in Fig. 2. A depression of a column selecting key at this time will effect a release of the carriage and will arrest the carriage through the coperation of the depressed column selecting stop with the stop 108 on the frame of the machine. Tf, for example, the third column selecting key bearing the inscription Parts be depressed the carriage will be released and arrested through the cooperation of the third column selecting stop, counting from the left, with the stop 108, the first two column selecting stops being skipped. This is effective to arrest the carriage in the columnar field c indicated by the heading Parts. A denominational key is then actuated in accordance with the number to be written and a number, up to one including siX digits, in the present example, may be written in the properly selected columnar field. The neXt or any succeeding column may then be selected as before, and a denominational key actuated as previously described to secure a proper denominational positioning of the carriage to begin the number to be written in the appropriate column.

While I have shown the column selecting mechanism of my invention embodied in a No. 11 Remington machine, it will be underof thecolumn selecting mechanism herein shown and described.

By removing the rod 102 any desired number of key carrying column selecting stops maybe placed on the rod and the rod readily replaced'.y l have shown the employment of six of such-stops in the presentinstance merely by way of example, this'being all vthat is required for blanks of the character indicated but this number may be varied at will.

It will be seen thatby my present inven-` tion thecolumn selecting stops are separate andindependently adjustable; that the column selecting' mechanism may be used merelyl as such independently of the denominationalselecting mechanism `or may bel used in conjunction therewith to first select a columnar field and then effect a proper selection of the denominational position within that columnar eld, or may be used in conjunction vwith the column selecting mechanism ofthe No.' 10 Remington machine. On the other hand, the denominational mechanism herein shown may be used alone for the selection of denominational positions within succeeding columnar fields determined by the positions of the column stops 9S; or the denominational mechanism as hereinbefore described may be usedin conjunction with the column selecting mechanism.. Ity will be understood, therefore,

that the construction of my ,present inven-y tion is adapted to awide range of .uses and the tabulating mechanism asawhole is operative differently under varying conditions of use. the invention may be readily embodied in existing forms Vof typewriting machines, such, for example, as the-No.lO Remington machine or the No. 11 Remingtonymachine without modifying, or materially modifying, the structuraly featuresof such machines as they now exist and that-the column seL lecting mechanism V,is simple-in construction and eective in operation. o' Various changes may be made without departingfrom'thespir-it and scope of myinventiOn., o l v v .y i What Iclaim as new and desire to secure by Letters-Patent, is Y 'Y 'o l.
