I have-shown my invention embodied in the present. instance in a No. 10 Remington machine in which the invention may be readily employed without modifying the structural features of said machines as they.

base 1, corner posts 2 and a top plate 3. 'A' carriage,re-presented as a Whole by the reference numeral 4, supports a rotative platen 5 and is supported by anti-friction balls or rollers 6 for movement from side to side of The carriage is propelled by the usual spring drum 7 operatively connected to the carriage by a strap or band 8, the carriage being controlled in its step-by-step letter'space movement by the usual escapement mechanism; Thus a feed rack 9 is supported on arms 10 pivoted at 11 to the carriage. One or more springs 12'codperate with the arms 10 to pressthe feed rack into mesh with a feed pinion 13. The feed pinion is connected in the usual manneriwith a double escapement wheel 14-, coiiperative with a feed dog 15 to control the letter space movement of the carriage. The feed dog is carried by a dog rocker 16 pivoted at 1,7 to a bracket l8which latter is fixedly secured to the frame of the machine. The 'dogrocker is controlled in the usual manner from vthe universal bar 'act'uated at each depression of a printing key 18% Each key is connected through a key lever (not shown) links 19 and'20, and a sub-lever 21' with an upwardly and'rearwardly striking type bar 22 which strikes against the front face of the platen. The usual carriage release key 23 forms a part of a lever 24* which is pivoted at 25 toan end bar of the carriage, the rear end'of the lever extending beneath the feed 'rack Qto lift it and thus disengage the rack from the feed pinion to free the carriage from control of its escapement mechanism. ,The lever 24 is slotted :at 26 to receive a headed screw 27 receivedat its threaded end in a tapped opening in. the carriage. frame. The screw 27 guides theforward end of the lever 24 and ,li ni.' ,the niovement thereof. There may bef one of these release keys and levers at each's'ide of the carriage; v-A pointer 28 is fixed byfa screw 29 to the forward fixed carriagerail and ,cotiperates with acarriage scale 30 carried by the forward cross bar of the carriage.

The parts thus far described are or may be of the usual construction embodied in the No. 10 Remington machine Forwardly extending bracket arms 31 are shanks of the screws will be received in the A upright portions of the slots. 33, thereby preventing a longitudinal displacement of the rack 34 relatively to the bracket arms 31 by which the rack is'carried. If the thumb screws 32 be tightened at this time the rack will be constantly maintained in carrier so that the latter in its rotation will move in unison with the carriage during the travel thereof. If, however, the operator desires-to disconnect the carriage entirely from the tabulator. mechanism so as to render the latter ineffective, it is merely necessary to lift the rack until the longitudinally extending portions of the slots 33 are in register with the shanks of the screws 32 and then. effect a slight longitudinal movement of the rack in order that the shanks of the screws-may be seated within such longitudinal portions of the slots. The effect of this adjustment of the rack is to disengage therack from the teeth on the carrier'and'maint ain the rack elevated above andclear of the teeth 35 on the carrier. By

tightening the screws 32 the rack may be retained indefinitely in this position.

The carrier 36, is inthe nature of a wheel or rot ative member provided, as hereinbefore explained, with teeth 35 on the periphery thereof. This wheel rot-ates on a spindle 37 which forms part of a bracket engagement with the teeth 35 of the rotative designated as a whole by the reference numeral 38. The bracket 38 may be detach-' ably secured to the frame of the machine at the front portion thereof by headed screws 39, which pass through openings 39" in a foot" piece in the bracket and engage in tapped openings in thecross bar 40 of the frame. of the machine. It will be seen that the rotative stop carrier or wheel 36 is supported in an-upright position at the front of. the machine and centrally thereof. It'

will be understood from an inspection of Fig. 4 that the axis of the wheel is in a vertical plane which extends fore and aft of the machine and cuts the printing point and printing point indicator 28. The wheel or stop carrier is slotted radially throughout near the periphery thereof. as at- 41 (Fi l) for the reception of a series of circularly arranged column stops .42. each of which may be constructed as best shown in Figs. (3 and T. Each stop is preferably made of sheet metal and is slotted at 43 to provide a spring hearing portion ll. This arm is provided at its free end with a nib or enlargement l5 which prevents an accidental displacement of the stop from the slot in which it is received when the stop is projected to the operative position. as shown in Fig. 7. The opposite end of the stop is likewise provided with a log or projection it) which limits the longitudinal movement of the stop in the opposite direction. as indicated in Fig. 6. The log 46 and nil) thus co-actwith the holly portion of the wheel or stop carrier to limit the stop in its movement fore and aft of the machine, or into and out oil operative position. The spring arm or portion ll. which formed integral with its stop. constitutes a spring hearing 11 ember which enables a stop to be sprung into place within its slot or to he removed therefrom. Thus by depress ng the nib 45 to 'ard the body portion of the stop until the nil) clears the associated wallof the opening, the stop may he withdrawn from the slot and detached from the carrier. Fig. l shows the parts as they appear with some of the stops removed. In a like manner a stop may he introduced into place by pressing the arm all against the body portion of the stop and introducing the stop into an opening in the carrier until the nil) 4:5 passes to the rear face of the carrier where it will spring back to normal position, preventing an accidental withdrawal of the stop. Moreover, the effect of this integral portion of the spring stop is to produce sutlicient friction between the stop and the end walls cf :1 slot to hold the stop indefinitely in the operative or inoperative position to which it may be moved on the carrier. .in the present instance I have shown one hundred and twenty stop openings arranged in a circle iii the stop carrier. and each opening is adapted to receive a stop moved on the carrier forwardly to the operative position at the front of the wheel or carrier. as indicated in Figs. 5 and or rearwardly to the inoperative position at the back of the wheel. as indicated in Figs. 3 and rirrangecl within the circular series of column stops is a series of circularly arranged indices 47 inscribed on the front face of the stop carrier.- There are as many of these indices as there are stop receiving openings .41 in the carrier and the indices are correspondingly located. These indices are adapted to he brought succes- -l2 which may hel l 1 i 'inaintained spaced 77 C; 7." Li 1 7, C4 .57.

sively into register with by a screw 49 to a sleeve 50 which is mounted on the forward end of the hearing portion or spindle 37 on which the wheel turns, and by which sleeve the wheel or stop car rier is held in position on the spindle. it will he understood that a traveling movement of the carriage is eti'ectivc to turn the stop carrier and to bring the indices -27 thereon successively into register with the fixed pointer The spacing of the indices corresponds to that on the ordinary carriage scale and such indices 4:? will accurately register the position of the carriage. at any point inihe travel thereof. as will he readily understood from an inspection of Fig. lwhere each pointer and LS points to an index mark that indicates the.

same position oi the carriage.

i have provided cooperative key controlled.tahulator mechanism to co-act with the column stops which are in the operative position. in the present instance this coacting key controlled tahulattrr mechanism comprises a series of denominational stops 5i which are in the nature of depending arms on angular levers The forwardly projecting arm of each of these levers carries a key which bent latcrally. as

indicated in Fig. By the tanning arrangement of the lever arms 5?) I am enabled to provide sutlieicnt room for the the noininational he; olin a. single row across the machine and above the keyhoard and yet arrange the stop bearing portions or arms 51 of the levers in a comparatively small, widthwise space. as will he seen upon reference to Figs. l and 5. T he various levers 52 are pivoted on a pivot rod received and supported at its ends only in hearings 56 and secured therein by set screws 57. Those portions of the levers which are aper' tured to receive the pivot rod cooperate with spacing washers 55 supported on the pivot rod and by which the levers 52 are apart and are guided. Each hearing 56 is fOIlHQtl as a part of an arm 58 which extends forwardly and in-' wartlly from thehracltet 38. the arms 58 preferably being formed integral with the bracket 38. From aninspection of Fig. l it will be seen that the denominational steps 51 are arranged at letter space distances apart. corresponding to the spacing of the column stops on the stop carrier. and that there are eight of these denominational stops. each controlled by a separate key 5%. and that these keys. reading from left to right, indicated in Fig. 5,-are inscribed with *indices Iii 100T lOT. T.

it will be noted indices on the de the natural order numerals inscribed that there is less that this reading of the noniinational keys is in in which the reading of on the sheet occurs, and

a pointer e8- fixed Git confusion in the mind of the operator in actuating the denominational keys than is the case where the inscriptions on the keys are in the reverse order of that inwhich the numerals actually appear when written.

Each lever 52 is provided with a stop finger 59 which co-acts with a depending portion 60 on the collar 50 to arrest the denominational stop lever in its return movement to normal position. The return move ment of each denomination stop lever is effeoted by a contractile spring 61 connected at one end .to the lever, as at 62, and connected at its oppdsite end with the depending portion 60 of the collar 50. Therear end of the spring may be connected to the collar by extending through an opening in the portion 60 thereofand having a hook 63 on the end of the spring to connect the spring with the member 6 I In order to effect a release of the carriage at the actuation of any of the denominational stops, I have. provided a universal bar 64 which extends beneath the forwardly projecting arms 53 of the levers 52. The ends of the universal bar are bent inwardly and ,rearwardly to provide two supporting arms 65 and 66 whichare formed with bean:

ing portions 67. The bearing portions of the arms 65 are apertured to receive the pivot rod 55 so that the universal bar, as

by depending arms 70 on the carriage. The

arms 70 are pivoted as at 71 to cars formed on the brackets 31. One of the arms 70 is provided with a rearwardly extending arm 72 which is received in a slot- 73 formed in the release lever 24. In the No. 10 Reining.

ton machine there are two release levers 24 provided and, if desired, each of the arms understood that a depression of a denominational key is effective to turn the associated stop lever 52 to the position indicated in Fig. 8, thereby bringing the associated dc- ,nominational stop 51 into the path of those column stops which have been moved forwardly to the operative position, and'at the same'time the release arm 68 will be moved I forwardly to effect a forward movement of the bail 69, thereby actuating the release lever or levers 24 to lift the feed rack and free the carriagefrom control of the escapement mechanism. When pressure on the depressed denominational key is released, the

parts will be returned -.to normal position after the carriage hasbeen arrested 1n the denominational position determined bythe particular denomination depressed. I

The means by which the column stops are set or moved to operative position will now be described. Extending centrally through a bearing opening in the fixed.

key which has been spindle 37 on which the stop carrierrotates,

expansion spring 76 surroiinds the stem 74 and bears at one end against the finger key 7 5 and at its opposite end against the for-.

ward end of the spindle 37-, the power of this spring being exerted to normally main-- tain the key 75 in the forward position represented in"Fig. 3. The rear end-;of,the

stem 74:, is slotted, as at 77, to receive the" upper end of a stop setting device 78 which is pivoted at 7 8 to the stem. The stop setting device is in the nature of a lever of the first order pivoted at 7 9 .on rearwardly extending ears 80 that project from the bracket 38. The body portion of the bracket is slotted at 81 to receive .the stopsetting device or lever 78 and enable the lower end thereof to be projected forwardly beyond the front face of the bracket 38 to the operative position represented in Fig. 7. The width of the engaging portion 82 of the'stop, setting device is such that it can coact with but one column stop 42 at a time to move the column stops forward from the position v 1 represented in Fig. 3 to that shown in Fig.

. I. The effect of this movement of a. column stop 18 to bring it from a position from the rear side of the stopcarrler where the stop is in the inoperative position, to a position at the forward side of the stop carrier where the stop is in the operative position. It will be understood that a rotative movement of the stop carrier is effected by an intermit tent letter feed movement of the carriage in the direction of its feed in order to bring the column stops successively in register with the engaging end 82 of the stop setting device, so that .the latter when actuated may engage the registering stop and move it tooperative position. The stop setting device is therefore operative individually successively and selectively to. move the column stops to operative position. They are moved selectively into operation 111 the, sense that any desired column stop may be moved to operative position as determined by the position of the carriage in its line of travel.

The means for clearing the stops or returning them to normal inoperative posi-- tion consists inthe present instance of a clearing device designated as a whole by the reference 83. This device includes a hub portion 83" pivoted on the pivot rod 55 and and adapted to move.

having :1 depending arm 84 provided with a linger piece 85 by which the clearing device may be turned on its pivot from the normal position shown in Fig. 3 to the operative position represented in Fig. 6. The clearing device is provided with a laterally projecting arm 86 having an inclined face 87 which constitutes a cam orwiper which is cooperative with the column stops to cam. them 'rearwardly from the operative to the inoperative position, as represented in Fig. (3. It will be understood that the column stops are brought successively into cotiperation with the wiper to cain them to inoperative position during the. travel of the carriage from-right to left The lower end of the clearing device 83 is provided with an engaging device or pawl 88 pivoted. thereto by a shouldered pivot screw 89. The pawl 88 is provided with a shouldered portion 90 (Figs. 4 and 0) adapted to contact with the body portion of the clearing device to limit the rotatiw movement of the pawl 88 on its pivot 89 in one direction. A leaf spring 91 is secured at one end, indicated at 92 in Fig. 3', to the body portion of the clearing device and bears at its free end portion against the pawl 88 to hold it normally in the position represented in Fig. 4: with the engaging portion 90, limiting the movement of the pawl around its pivot 89.

A cooperating engaging member designated as a whole by the reference numeral 92 is mounted to slide vertically in a hous ing 93 secured by a screw 94 to the bracket 38. The upper end portion of this member 92 is provided with an engaging nose 95 which is beveled at 96 and is adapted to cooperate with the pawl 88 when the clearing device is moved rearwardly to the operative position, as shown in Fig. 6. The engaging member 92 is also provided with a forwardly extending finger piece 97 which extends through a slot 98 in the housing 93. The engaging member has :1 depending spindle 99 which extends through an opening in the bottom of the housing and a nut .100 is threaded on the lower end of the spindle. An expansion spring 101 surrounds the spindle 99 and bears at its lower end against the bottom wall of the housing and at its upper end against the body portion of the engaging device 92. The power of this spring is therefore exerted to normally maintain the engaging member 92 in the elevated position with the nut 100 bearing against the bottom of the housing in which the engaging member is received 7 It will be understood that a rearward movement of the clearing device 83 is effective to bring the lower-endof thepawl 88 into contact with the inclined face 96 of the engaging member 92 and to depress said engaging member until the pawl has passed behind the engaging nose 95 on the member 92. Then the latter is elevated by its spring 101 to bring the engaging nose 95 forward of the pawl 88 and thereby automatically lock the clearing device against return movement. This locking engagement, however, may be released ,at any time by a depression of the finger piece 97 and when thus released the clearing device will be returned to normal position shown in Fig. 3, by a leaf spring 102. This spring is fixed at one end to the clearing device by a screw 103 and bears at its free end against a pin 104, which projects inwardly. from the left-hand bracket arm 58.

I have provided automatically operating means tor releasing the carriage from control of the escapement mechanism when the clearing device is operated so that the carriage traveling under the influence of its driving spring may wipe out or clear the column steps which are in the operative position. Thus from an inspection of Fig. 5 it will be seen that the hub 83 of the clear ing device is reduced at one end, at 105,

and has seated thereon and fixedly connected therewith a forwardly projecting arm 106. This arm is bent to the left from the hub 83 and then extends forwardly to overlap the universal bar 64 by an actuation of which the carriage is released. It will be seen. therefore, that .a rearward movement of the clearing device to the operative position shown in Fig. 0 is eiiective to turn the arm 106 downwardly, thereby depressing the universal bar 64: and moving the upwardly extending arm 68 connected therewith forwardly, as represented in Fig. (5, to effect a forward movement'of the universal bar 69 and thus release the carriage. If the carriage be at the extreme right when the clearing device 83 is moved to and locked in the operative position shown in Fig. 6, a simultaneous release of the carriage is effected and a revolution of the stop carrier is effected, bringing all the column stops successively into engagement with the cam or wiper 87, to clear all of the column stops or move them rearwardly on the carrier to the lnoperative position.

In order to automatically release the clearing device from its locked positioml havefprovided a releasing device which is. fixed on the stop carrier 30. This device comprises an angular bracket 10? havmg'a forwardly engaging portion 108, thebracket being detachably secured by screws 10901 1 riphery thereof. From an inspection of Figs. 3 and (3 .it will be understood that the engaging portion 108 of the releasing de vice has a rotative path of movement which other siiitable means to the forward face of 1 the rotative stop carrier 36 near the peleased.

tion by said pawl. The position of the releasing bracket 107 on the stop carrier is such t' i it is notbrought into cooperation with the pawl 88 until all of the column stops have been cleared by the wiper 87 as will hereinafter more clearly appear. When,

however, the stops have been cleared by the wiper, the releasing device will be brought into engagement with the pawl 88 before the carriage has completed its movement and the effect of this engagement between the device 107 and the pawl 88 is to turn the-latter on its pivot 89 to the right against the power of the spring 91. The pivotal movement of the pawl to the right in the manner described is effective to withdraw the pawl from engagement with the spring presseo engaging member 92 so as to enable the clearing device 83 to be returned to normal position by its spring 102. In order to limit the movement of the clearing device 83 and the arm 106 carried thereby, I have provided a pin 110 .fixed in the lefthand bearing portion 56 of the supporting bracket, this pin projecting into a slot 111 formed in the bearing portion-of the warm 106. The pin and slot 110 111 is thus efiective to limit the return movement of the clearing device 83 and'to normally maintain the armfl06 in a position above the,

universal bar 64:, as shown in Fig. 3, where there may be suflicient lost motion between the arm 106 and the universal bar to enable the wiper to be brought'substantially into operative position before the carriage Jsre- While I prefer to employ as many, or substantially as many, colunm stops as there are letter space positions of the carriage in the travel thereof, it should be. understood I that this is notnecessary in all instances as Moreover it will be understood that the construction is such that the rotative column it may be found sufiicient to provide a series of column stops grouped. at letter space in: tervals and corresponding in number'to only a portion of the travel of the carriage.

stop carrier, column stops, stop setting defice and stop clearing device may be employed in connectionwith carriages of dilferentlengths; Thus,'I have shown a construction in the present instance in which provision is made for the use of as many as one hundred and twenty column stops arranged at letter space" intervals. This enables the mechanism -to be used in connection with carriages. of different lengths up to one hundred and twenty letter spaces. For example, if "a carriage in which provision is made. for a feed ot but seventy letter spaces is provided, then only a corresponding number of column stops on thestop carrier need be employed. However, thoperations will remain the same as for a carriage of greater length and no change in the construction of" the features mentioned is required, except that an adjustment of the releasing device 107 may be required.

Carriages are generally made in standard lengths, such, we will say for example, as to provide for seventy-five, ninety-five, and

one hundred and twenty letter spaces. It may be assumed that in the present case a carriage of a length to provide for seventyfive letter spaces is employed. It will be' shown in Fig. 4 by the positions of the screw holes112 inthe carrier.- I prefer, however,

to employ a releasing device such as is shown in Fig. 3 and in which the releasing device as a whole is'd'esignated by the reference numeral 113 and comprises 'a contact portion 11 1 is. formed as a part of 'a carry portion 114, corresponding to the part 108' v 'ing member 115 which resembles the column stops except that there is no movement of t-he releasing device.113 fore and aft of the machine in the slot 41 of the carrier. The spring finger 116 with its enlargement, however, enables meto adjust the releasing device to any opening 41 around the wheel 36 by springing the supporting portion of the device into place. It will be understood that with this device it may be adjusted to ary letter space interval provided by the series'of circularly arranged openings 11.

I have referred in the accompanying claims to a constantly maintained operative connection between the carriage and the rotative carrier for the column stops. It should be understood that b this and like expressions I mean tp 'inclu e a construction like that shown, for example, in which whenever the tabulating mechanism is in condition for use, or is effective or, operative for the purposes for which it was devised, there is a constantly maintained operative connection. between the carriage and stop carrier,v although the carriage and carrier may be disconnected by means, such for example as are-gsh'own in Fig. 2, when the use of the tabulatoristo be dispensed with incarriage scale by the coiiperation of said,

stop withthe decimal stop. While this ,parting from my invention and certain teato cause the latter to rotate during the travel -'stantly maintained operative connection bedefinite relationianot maintained when the rack 34: is thrown out of mesh with the carrier, nevertheless the relation may be quickly reestablished by moving the .carriage to a letter space position on the carriage scale corresponding to that of the rotative carrier, the position of the latter is indicated by the pointer 4&8 and the indices l7, before throwing the rack 34: back into mesh with the teeth 35.

Various changes may be made Without detures may beemployed Without others.
