21 Claims. (Cl.197-177) My invention relates to typewriting, and like machines, and more particularly to tabulating mechanism therefor.

The main object of my, present invention, generally stated, to provide means whereby one or more predetermined variations in the columnar positions of arrest of the carriage, not provided for by'the automatic tabulator operating under normal conditions, may be attained without modifying the set-up of the machine in switcl'iing from one set of columnar positions of arrest to another.

To the above and other ends which will here-- inafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly pointed out in the appended claims.

Fig. 19 is a full-sized, fragmentary, top plan view of the tabulator rays and associated parts.

I have embodied my invention in the present instance in a No. 23 Remingt'on accounting machine equipped with theusualfront feed billing mechanism, motor driven carriage return mechanism, etc., but have not shown some of the last mentioned features or the computing mechanism, and have illustrated only so much of said machine as is necessary to arrive at an understanding of my invention in its embodiment therein. It should be understood, however, that the devices or" my invention are not restricted to use in such machine, but maybe employed in typewriting and like machines generally, wherever found available.

The present invention is in the nature of an improvement on the machine disclosed in the patent to Frederick A. Hart, No. 1,710,685, dated April 39, 1929.

In said prior machine means are provided for automatically tabulating to successive columns of a bill form for filling in items, on a combined gas and electric bill, for example. This same result may be performed on the machine ofmy present invention. However, it oftenoccurs that the consumeruses only gas, or only electricity, and the same blank bill form is used in any of the three events mentioned, although only oer tain of the columns used in a combined electric light and gas bill are filled in when gas only is consumed. and certain other columns of the combined bill are filled in when electricity only is consumed.

It is one of the mainpurposes of my present invention to provide means whereby the machine may be readily employed fortabulating and fillin in at will the bill forms for any of the three conditions mentioned above. without changing the set-up of the tabulator stops'or other features of the machine, and in any one of the three instances mentioned different columnar positions of arrest will be automatically attained, at least in part, as will be hereinafter more fully explained. V In carrying out my invention in the present instance I provide a construction in which an actu ation of one key will effect a tabulating operation and also result in bringing about, with the aid of automatic tabulating operations, a selection of one set of columns, and an actuation of another key will effect atabulating operation and will also result in bringing about,with the aid of auto matic tabulating operations, a selection of another and different set of columns without changing the set-up of the tabulating mechanism, and without interfering with the use of the automatic tabulator under ordinary conditions in bringing about the selection of a third set of columns which include those of the first two sets.

Expressed from another point of view, the machine of my invention includes automatic tabulating mechanism whereby a predetermined set of columnar positions of arrest of the carriage 'may be automatically attained, and also includes key-controlled means by an actuation of each of the keys'of which certain predetermined automatic tabulations may be eliminated and a skipping effected of certain columnar fields attained with the aid of the automatic tabulating means, thereby enabling the operator to tabulate to various predetermined columnar fields as determined by an automatic tabulating operation alone or by an operation of one or another of said keys in conjunction with the automatic tabulating mechanism. The foregoing described selection of one or another set of columnar field-"s is attained without changing the set-up of the machine and merely results, in the present instance, from the use of either of said keys or the non-use of either of them.

i In order to carry out these results I embody the novel features of my present invention in a machine such as is disclosed in said Hart patent without modifying, or materially modifying, the existing structures thereof.

The frame of the machine comprises a base 1, corner post 2 and top plate 3. The carriage which supports a cylindrical platen (not shown) is mounted in the usual manner to travel from side-to-side of the machine over the top plate, being impelled in the direction of its feed by the usual spring drum, not shown. The carriage comprises a truck having front and rear cross bars 4 and 5, respectively, united by end bars. The cross bar 5 is grooved to receive crossed bearing rollers 6 that likewise are received and travel in a grooved guide rail secured to the top plate of the machine. The front cross bar 4 of the carriage is supported and guided in a like manner.

The step-by-step letter-feed movements of the carriage in the direction of its feed are controlled by carriage escapement mechanism which comprises a feed pinion 8 that is adapted to mesh with a feed rack 9 carried with the carriage and having a full complement of teeth throughout the efifective length thereof. From an inspection of Figs. 2 and 4, it will be seen that the feed rack is connected by screws 19 to depending rear portion 11 of a frame 12 that in cross section has asubstantially inverted U-shape. The forward arms of this frame are pivoted to the rear cross bar of the carriage on pivot screws 13 in order that the feed rack may have a pivotal movement into and out of mesh with the teeth of the feed pinion 8, being returned to and normally held in meshing engagement by a returning spring 12 as shown in Fig. 4.

The feed pinion is operatively connected through the usual backing ratchet wheel 14 and pawl 15 (see Figs. 1 and 4) with an escapement wheel 16. This connection causes the escapement wheel and feed pinion to turn together in the stepby-step letter-feed advance of the carriage to the left under control of feed dogs 17 and 18, and enables the feed pinion 8 to turn independently of the escapement wheel in the return movement of the carriage to the right. The pawl 15 is pivoted at 19 on the escapement wheel, whereas the backing ratchet 14 also constitutes a back spacing wheel with peripheral teeth with which the usual key-controlled back spacing pawl 20 coacts for back spacing the carriage.

In addition to the feed rack 9, the carriage carries a second or mutilated tabulating rack 21, shown in detail in Fig. 5. This rack is secured by screws 22 to a second frame 23, pivoted by forwardly projecting lugs 24 to the rear cross bar 5 of the carriage on the pivot screws 13. A flat spring 23 normally holds the frame depressed to a position limited by the usual stop 23 shown in Fig. 2. The teeth of this mutilated rack are adapted to mesh with the feed pinion 8, the latter being prolonged for this purpose.

From a consideration of Fig. 5 it will be seen that the mutilated tabulating rack 21 in the present instance has uninterrupted groups of teeth at opposite end portions thereof, as indicated at 25 and26, whereas at various intervals intermediate these groups are cut-outs or mutilations 27, 28, 29, 30, 31, 32, 33, 34 and 35, leaving in the specific instance shown, one, two or three teeth, as indicated at 36, 3'7, 38, 39, 40, 41, 42 and 43, between adjacent mutilations. This is in order that when, during the feed of the carriage, a mutilation in the rack 21 reaches the feed pinion 8, the carriage may automatically receive a tabulating movement to the next columnar position, for at this time the feed rack 9 is out of engagement with the feed pinion as will presently more clearly appear. When the next on-coming tooth of the multilated rack reaches the feed pinion, the carriage will be arrestedin position to make an entry in the column determined by the particular tooth in question. This, in accordance with the present showing, enables the operator to write two, three or four characters before the carriage jumps to bring the next-columnar field to the printing point.

From an inspection of Fig. 4 it will be seen thatjthe frame 12 of the feed rack carries a stop or set screw 44 that is threaded therethrough and has a lock nut 45 for securing it in its adjusted position. The lower end of this screw extends to a point above the tabulating rack 21 so that when the latter is lifted and disengaged from the feed pinion 8, the feed rack 9 will likewise be disengaged from said pinion, although the feed rack may be lifted independently of the tabulating rack and the mutilated rack may be lowered independently of the feed rack.

Secured by screws 46 on the front side of the mutilated rack is a bar or plate 47. The lower edge of this plate extends to and terminates at the lower ends of the teeth of the mutilated rack and forward of the feed pinion 8. This is in order that the rack-lifting shoe 48 (see Fig. 3), when elevated, will come into contact with the lower edge of the plate 47 and lift the mutilated rack without entering the mutilations or cut- outs 28, 29 etc., in said rack.

It will be understood that after each automatic tabulating movement, the feed pinion 8 is contained within one of the cut-outs or mutilations 2'7, 28 etc., in the rack 21, with one of the teeth 36, 37, etc., bearing against the pinion and holding the carriage against further advancing movement. Ordinarily at this time a reverse or back spacing movement of the feed pinion 8 would merely result in turning said pinion in the cut-out in the rack 21 without effecting any backward movement of the carriage.

In order that back spacing of the carriage may be effected from any tabulated position controlled by the mutilated rack, the same means Jthatare disclosed in said Hart patent for this purposeare employed herein, and will now be briefly described. wn in FigsqZ, i and 7, a contact device '9 is secured by screws to the rear side or b e feed rack 9. This block has a rearwardly ext riding projection 51 that overlies and -"l ally bears on a cam or controlling .bar, a whole by the ref rence numeral 5.2 and shown in detail Fig. 6. This barhasa series of depressions 53 in the upper side thereof. one such de ression being provided for each tabulated posi on or" the carriage automatically attai ed with the aid of the mutilated rack ,21. ermediate each adjacent pair of.depressions is a cam member or projection 54 havinga right-hand in face 55, an elongated dwell at "b top or the projection and an abrupt verti ce 5!? at the left-hand side of the proection. It will be understood that the cam bar s mounted on the top plate of the machine and "rat the pro ection 51 traveling with the carriage ride: alongthcjtop of cam bar until it reaches a depression 53 and drops therein. This is at instant that the carriage is arrested, aftera tabulatiiig movement, by one of the teeth of the r d rack. The effect of t'ne projection 51 "upping into a depression 53 is to lower ck 9 into mesh with the feedpinion t if the latter be back spaced at this carriage will likewise be back spaced. spacing is sometimes required when, ins ance, the entry in any column requires "g at any higher denominational position "narily required. Should a lower deo for by the mutilated rack, then :1 op aticn of the usual space key will advance the cailiage, say, one space from its position of arres' by the taoulator rack, although this is seldom required. In the use of the back spacer let us assume, for example, that the tabulator ra is so cut that in making an entry on the cm shown in Fig. 18, in the column under the caption Elect. s, the entry will start in the hundreds or position, whereas the amount of the entry, occurring only occasionally, requires beginning the entiry in the fourth or thousands position. A single actuation of the back spacing key will properly space the carriage to receive the entry. And this is true of each column where such condition exists.

The carriage having been arrested by the automatic tabulating mechanism in the manner described, the operator proceeds to make the requisite entry in the column at the printing point and as soon as the entry is started the cam face 51 on the-projection 51 willride up on the ent cam race 55 on the cam bar 52, thus ng the feed rack 9 and disengaging it from the feed pinion.

tained by the projection 51 riding along the companion dwell 55 until the next automatic position be required than that ordi-,

This disengagement will be One of the bracket arms .61 securedto the cam bar, and by which it .is pivotally mounted, is prolonged to provide an arm 62 that extends below its pivot 58 and terminates in a hook-like end 63 to which one end of a contractile returning springfi i is connected,,the.0ther end of said spring being anchored on a pin .65 on the top plate. The force of the spring 64 .isexerted to return the cam bar to normal position v.shown in Fig. 4, and to normally hold the bar in such position.

The right-hand wall of each depression 53 in the cam bar has atthe forward position thereof an inclined cam face 66 with which the edge 51 (see Fig. 7) of the projection'51 is adapted -to coact in a movement of thecarriageto theright,

and thus cam the bar 52 rearward out of the after described.

As in the construction disclosed in said Hart patent Iemploy link 67 (see Fig. -1) pivoted at its lower end, as at 68, to a crank arm69 adjustably secured to a rock shaft 70 of the usual power actuated carriage return mechanism. The upper end of the link 67 is slotted at 71 (see Fig. 4) to receive a-pin '72 carried by an armoi a bracket 73 secured by screws 74 to the-rear side of the cam bar 52. This link 67 limits theforward movement of the cam barunderthe force of its spring64.

When an operation ofthe parts is initiatedto eifect a return of the carriage by the power actuated means, the shaft '70 is rocked, thereby pulling down the link 67 and moving the cam bar 52 rearward against the force of its spring 64 and out of cooperative relation with the projection 51. Thisrenders the cam bar 52 ineirective to successively raise and lowerthe feed rack '9,

as said'bar does automatically during the forward movement of the carriage.

It, has been found in practice that occasionally during a very rapid and vigorous actuation of the back spacing key, the edge 51. of the projection 51 in operating on the adjacent cam face 66 during aback spacing operation, lifts the projection 51 instead of merely camming the bar 52 to ineffective position. The result would be that no back spacing would occur, and if the operator failed to note this, an entry would be made'in the wrong denominational position.

:To overcome-the above mentioned difiicultv- I have provided specialmeans controlled by the back spacing device .and acting directly on-the cam bar 52 to moveit intosineffective position. without relying on the cam faces 66 to attain this result. l

Such means is bestshown in-Figs 1, 2, eiand 6, and includes an actuating; finger or projection 75 extending-upward and off-set forward from a pivotedarm '76 to which; the: back spacing pawl 20 is pivoted. This-finger '75, during each back spacing operation, coacts with a cam .q'laon .a bracket-.78 secured by screws'79 to the rear side of the cam bar .52 abovethe pivots .58 thereof. The effect of this constructionuisrto earn the bar 52 rearward out of cooperative relation with projection 51 by .thedirectoperation of the back spacing mechanism on the cambar52, and there eiTectivepositionduringeach e'ntirebackspacing operation, and will not be returned to effective position until the back spacing mechanism has been returned to normal position.

If at this time the projection 51 should be out of register with one of the depressions 53 in the cam bar no harm will result, since the forward solid portion of the cam bar intermediate two adjacent depressions 53 will bear against the rear end of the projection 51 and the cam bar will be held out of operative position until such time as a depression 53 registers with said projection.

In order to prevent the feed rack 9 from being accidentally forced upward during the back spacing operation, there is provided a locking arm 80 which automatically moved upward from its normal iull line position, shown in Fig. 4, to

a locking position where it will overlie the frame 12 of the feed rack 9 and prevent the latter and the mutilated rack 21 well from being forced up out of mesh with its feed pinion during the back spacing operation. This result is attained by the following means. The arm 80 is formed with hub 81 by which the is pivoted between the arms of a yoke-like'bracket 82 secured by screws 83 to the rear fixed carriage rail 7. A spring 84 is coil d around the hub 81 and exerts its force to carry the free end of the arm 80 to the dotted line position shown in 1, where it overlies the frame 12 and prevents an upward pivotal movement thereof, thereby preventing a disengagement of the rack 9 and the rack 21 as well. In order to release the lockingarm there is carried thereby an off-set finger 85 which underlies a forwardly projecting pin 86 carried by the back-spacing pawl-carrying arm 75. When said arm is elevated during the back spacing operation, the pin 86 will move upward, thereby releasing the 80 and enabling it to be moved by its spring to locking position. When the back spacing key is released, the arm 76 will be returned to normal position by its spring 87 (Fig. 1) that is heavy enough to overcome the force of the spring and return the clocking arm 80 to the normal position, shown in full lines in 'Fig.

An important factor of the present invention resides in the provision of means, about to be described, when combined with features hereinbefore referred to, and which are operative to bring about a discontinuance in part of the operation of the automatic tabulating mechanism at one part or another of the travel of the carriage depending on the use of the machine for filling in bill forms for electricity alone, or gas alone, and depending on the actuation of a so-called electric key, or a so-called gas key.

Referring more particularly to Figs. 3 and 19 it will be observed that a tabulator is disclosed comprising a series of keys 88. In the indicating strip over one of these keys, shown at 89, I have placed the designation Elect, to indicate that this key is to be used when the tabulator is to be employed to fill in bill forms that are to contain items that relate to electricity and not to gas. Another of these keys, shown at 90, has the designation Gas on the indicating strips, to indicate that this key is to be employed in the event that the machine is to be used to fill in items in the bill forms that relate to gas and not to electricity.

Each of the keys 88, 89 and 90 is connected in the usual manner to a push rod 91, coacting at its rear end with a companion stop lever 92 pivoted intermediate its ends in a tabulator frame 93 and terminating at its upper end in a forwardly projecting stop 94. When one of said keys is pressed rearward, the corresponding stop 94 is projected forward into the path of a series of column stops 95 removably secured to, and adjustable to different positions along, a column stop bar 96 carried by the carriage. This same actuation of one of the tabulator keys carries a companion lever 92 against and actuates a universal bar 97 of the carriage releasing mechanism. This actuation of the universal bar 9'7 transmits motion through a sliding frame member or link 98 to an angular lever 99. Said lever is connected through a link 100 to a rearwardly extending arm 101 connected to the rack-lifting arm 102 that carries the shoe 48 at the forward end thereof. This operation results in lifting both racks 9 and 21, as hereinbefore described, and freeing the carriage from the control of the feed rack 9, the tabulating rack 21 and the escapement mechanism, allowing the carriage to run free in the direction of its feed until the first of the oncoming column stops 95 reaches the projected stop 94. After the carriage is thus arrested, the operator releases the actuated tabulator key and the racks 9 and 21 return to normal position prepared to function in the manner previously described to automatically effect a tabulating operation of the carriage after an entry has been completed in a column determined by the mutilated rack 21.

In the present instance I have selected what ordinarily corresponds to the units tabulator key for the Elect, key 89, and have selected the key 90 which ordinarily is used for the thousands key as the Gas key. In addition I connect a palm tabulator key 103 to the push rod 91 that corresponds to that ordinarily employed for the decimal stop except that it is connected to the palm tabulator key 103 instead of to one of the ordinary push keys 88. This connection from the palm tabulator key to this push rod 91 is made through a bell crank lever 104 actuated through a push link 105 from the depending end of a lever 106 of which the key 103 forms part. Said lever 106 has a yoke-like part 107 that is formed integral therewith, and this yoke is received between and pivoted at 108 to the arms of a bracket 109 secured to the base 1 of the machine.

It will be understood that in setting up the machine in the first instance the column stops 95 must be set in a definite relation with reference to the automatic control by the rack 21 and the mutilations therein, as well as in definite relation to the particular stops 94 controlled by the keys 89 and 90 in cooperation with said column stops, as will hereinafter more clearly appear.

The operation of the machine, as it is brought about in the present instance by the particular cutting of the mutilated rack 21 and the corresponding cutting in cam bar 52, for use in filling in the bill form A shown in Fig. 18 under the varying conditions hereinbefore referred to, may be best understood by referring to the diagrams shown in Figs. 8 to 1'7 inclusive.

Figs. 8-12, inclusive, show different successive steps of parts of the structure when it is used for filling in items in the bill form that relate to electricity. This will be described first after digit is writte ceive the entry of items with the aid of the pahn tabulator key 183 and an appropriate setting of related column stops 95. This is true whether the bill form is to be filled in for gas and electricity, alone, or electricity alone. The same is true ofcolumns o p and q although it should be understood that the mutilated feed rack may, if desired, be specially cut to take'care of these columns automatically, or some at least of them. it will be understood, moreover, that in filling in items in a bill form for both gas and electricity all of the columns e to 11, inclusive, will be brought successively and automatically into position to receive the items in the main under control of the mutilated rack 21, and that an operation of the Gas key 90 and Elect, key 89 is unnecessary.

Referring now to Figs. 8-12, inclusive, and to' the control of the machine for filling in items relating to electricity, it will be seen that Fig. 8 shows the parts as they appear after filled in items in column d, and after an actuation or" the palm tabulctor key 103 has been effected. The operation of the key 103 after filling in column d was eiiective to project the stop 94 con trolled by said key into the path of the oncoming column stop 95 the column stops being progresively indicated in Figs. 8-17, inclusive, by the addition of exponents a, b, 0, etc., to the reference numeral 95 in order that they may be clearly distinguished in their progressive steps. In a like manner the depressions 53 in the cam bar 52 have ,n'ogressive alphabetical exponents a, b, 0, etc., added to their reference numeral 53 in these views in order to clearly distinguish them, and the particular denominational stops 94 controlled by the palm tabulator key 163, by the electric 'key G9 and the gas keyed are designated in these views by the reference characters 94 94 94 respectively, in order that they may be readily distinguished one from another. The dot and line in these views indicates thecenter iiiof the feed pinion and approximately the brought into contact with the feed pinion to rrest the carriage in its tabulating movements under control or" said rack.

It will be seen, therefore, that an actuation of the palm tabulator key 103 after filling in the column d will leave the parts in the position wn in Fig. Sready to start writing the highest of the four digits indicated by :r-marks in the column 6. At this time the third from the last of the teeth 28 of the mutilated rack engages the pinion. This permits the writing of four digits in column 6, and after the fourth or last the space in the rack 21 reaches the feed pinion, permitting the carriage to automatically jump the required distance to start writing the highest of the four digits at in column f. A like automatic tabulating movement of the c-.rriage is effected to bring the column 9 into position for writing the highest digit in after w. ng of the two digits is made in column gv and the carriage automatically jumps after writing the last digit to bring the gas column h to printing position. However, inasmuch as no entries are to be made for gas, the electric key 89 is pushed in, causing the mutilated and feed racks 21 and 9 respectively to be elevated to ineffective position where they do not operate to control the carriage, at the same time projecting the stop 94 into the path of the column stop 95 thereby to clear the gas our from columns 2' to y and from having osition where the teeth of the mutilated rack the last digit in column 1. The entry efiecting an arrest of the carriage in this manner,

as indicated in Fig. 9. When pressure on the actuated key 89. is released, the stop 94* will be withdrawn and a further movement of the carriage will be effected, bringing the parts to the Fig. 10 position with the left-hand tooth 40 arrested by a Li pinion 8, it being understood;

that the release of the key 89 enables the mutilated rack to be lowered to effective position. The result of this operation of the electric key 89 was to bring column h and eiiect an arrest of the carriage position to bring writing in column Successive automatic jumps will occolumns 7 to is after writingthe last digit in each of the two first mentioned columns. When the gas column is is reached, this and thenext succeeding gas column Z are to be skipped to bring the Number column m into position to receive an entry. To bring about this result the electric key 89 is pushed in, releasing the carriage from the control of the automatic tabulator rack 21 and arresting the carriage by the column stop 95 as shownin Fig. 11. When pressure on the 3 key 89 is released, the stop 94 is withdrawn from entry. After this entry iscompleted the remaining columns may be filled in in any suitable manner.

From what has been pointed out above it will be understood that when a skipping of a gas column is produced by an actuation of the electric key 89, or a tabulating operation is effected by an actuation of the key 103, the projection 51' will be elevated out of cooperative relation with the cam'bar 52 so that the latter is ineifective to function at this time and will remain inefiective until the actuated'key 89 or 103 has been returned to normal position and the control of the carriage by the mutilated feed rack has been reestablished.

about a jump of the carriage It also will be understood that itis immaterial" whether or not the projection 51 is in register with a depression 53 or when the carriage isv arrested by eitherof the stops 94 0r .94 ,since at this time the said projection 51' is out of cooperative relation with the the projeccam bar. If at the time in question with a depression 53*, 53

tion 51 is in register etc., said projection will enter such depression when the racks 9 and 21 arelowered to bring the carriage into control thereof. IiIth projection 51 is out of register with such'a depression when the carriage is arrested by either of the stops 9% or 94*, as indicated in Figs. 9 and 11, then when the racks are lowered andthe pro- -jected stop 94 or9l is withdrawn, the carriage will continue to travel further to the left until arrested by the next on-corning tooth of the mutilated rack (36in the instance disclosed in Fig. 11) collided with the feed pinion.

the mutilated rack has thus been arrested, the

projection 51 will be in register with a depression 53*, etc., in the cam' bar J During such movement of the carriage, the projection 51 except 9, i and a may be filled in.

53 or 53* etc., and the feed rack 9 will be lowered into mesh-with the feed pinion prepared to bring about a back spacing of the carriage should the back spacing mechanism be actuated.

It is thought from the foregoing explanation given in connection with Figs. 8-12, inclusive,

that an understanding of Figs. 13-17 will be readily arrived at. These last mentioned views show some or" the same steps in the operation of the parts as those disclosed in the first mentioned figures, except that in Figs. 13l'7 the control is by the gas key 90, instead of the electric key 89, the operation of the key 90 being effective to skip the columns where entries are required relating exclusively to electricity, and entries, as

jindicated by the oo in the second line of the Summarizing the operation from a slightly different point of view, it will be understood that when any of the keys 89, 90 and 103 of the key controlled tabulator is actuated, the effect is to take the carriage out of control of the automatically operating tabulator mechanism comprising the mutilated feed rack 21 and place the carriage under control of the key controlled tabulator. When the key projected tabulator stop is withdrawn by the release of its key, the carriage is again restored to control of the automatically operating tabulator, or mutilated rack. In effecting suchrestoration it may occur in some instances, as shown in Figs. 14 and 15 for example, that the projection 51 will be located at one of the depressions in the cam bar 52, as indicated at 53 in these figures, when the projected key controlled tabulator stop is withdrawn. -In such event there will be no, or substantially no, movement of the carriage in restoring it to control of the multilated feed rack, since one of the teeth of the lowered rack 21 is at, or substantially at, the feed pinion. At the same time the feed rack is lowered into mesh with the feed pinion, so that the back spacer is operative to function if necessary.

In other instances, however, as indicated in Figs. 9 and 10 the projection 51 will drop on a dwell 56 on the cam bar when the projected tabulator stop is withdrawn. In such event the mutilated rack 21 will be lowered, although the feed rack 9 will be maintained out of cooperative relation with the feed pinion. The carriage at this time being no longer held arrested by the projected key controlled tabulator stop will advance until arrested by the next on-coming tooth of the rack 21. When such arrest is effected, the projection 51, will reach the next depression in the cam bar, indicated in Fig. 10 at 53. When-this occurs said projection 51 will drop into such depression, enabling the. feed rack 9 to reengage the feed pinion and enabling a back spacing operation to be effected, if desired.

It will be seen that every time the carriage is finally arrested in a tabulated position, whether such position be effected by the mutilated rack alone, by the key controlled tabulator alone, or by the combined use of the key controlled tabulator and the mutilated rack as pointed out above, the feed rack 9 will be reengaged with the feed present invention.

pinion 8,'so that a back spacing of the carriage may be effected from such position, if desired.

Ihave given a detailed description of one particular bill form which the construction was specificially devised, in the present instance, to be used in connection with. And I have given a detailed description of the operation of the machine in filling in such bill form under the three different conditions referred to. It should be understood, however, that various bill forms may be employed, and the machine in some respects is to be varied accordingly, and according to the special requirements in individual cases. For example, it may require varying cuttings of the rack 21 and cam bar 52 and varying adjustments of the columnstops 95 to accord therewith, for different variations in the character of the bill forms to be used, and the varying requirements thereof. However, inasmuch as one organization is apt to send out the same character of bill form even though'entries therein may vary as in the present instance, such special cutting, etc., is of no great moment, especially where a number of machines have their racks all cut in the same manner.

So far as the automatically controlled, power 1 actuated, carriage return mechanism is concerned, it will be unnecessary for the purpose of the present invention to describe such mechanism in detail, and it is illustrated only in part as hereinbefore indicated. The computing mecha- 1 nism likewise has not been illustrated, its disclosure being unnecessary for the purpose of the Parts of the carriage return mechanism are shown in Fig.2, wherein the usual contacts 110, 1

111 are operated on respectively by the carriage carried stops or contacts 112 and 112, respectivelyyto connect and start the motor at the end 'of the travel of. the'carriage from right to left,

and for disconnecting and stopping the motor 1 when the carriage arrives at the beginning of a line position in its return movement to the right.

The contacts 110, 111 are connected respectively to rods 11 1, 115, which, through intermediate devices, control means (not shown) contained within a control box 116 by which an arm 117 on the shaft is controlled to rock said shaft and in turn control the clutch and motor starting and stopping means, not shown.

It will be seen that by the present invention 1 am enabled to eifectively attain the results hereinbefore pointed out, and am enabled to embody the features of my said invention in the machine disclosed in said Hart patent without materially modifying any existing structural fea tures included in said machine. 'Various changes may be made in the construction, and some of the features thereof may be in cluded without others, without departing from my invention as it is defined in the accompanying claims;
