  • the stops or contact faces 7 8, 79, etc.' are out of the paths of the corresponding collars or stops 35 on the push rods 30.
  • the arresting member will be moved from the position shown in Fig. 1, to that-indicated in Figs. 3 and 4, where the contact faces 78, 79, etc., are in the paths of the corresponding stops or collars on the push rods, to variably limit the movements of the corresponding push rods relatively to each other.

  • a coiled spring 94 surrounds the pivot 89 and bears at one end against the depending portion 91 of the key 88, the opposite end 95 of said spring engaging a projection 96 on the part 90. The force of the spring is thus applied to normally maintain the key 88 in the position shown in Fig. 3, relatively to the arm 83.
  • a stop pin 97 is carried by the arm 83 and limits the movement of the key 88 around its pivot 89 back to normal position.
  • a depression of the key 88 is effective to turn it around the pivot 89, against the pressure of the spring 94, and at the same time to move the arm 83 down, so as to bring the stop faces or cross bar 76 of the arresting member into the path of the stops or collars 35 on the push rods.
  • the upper side of the index plate 98 is inscribed with column selecting indices 10", such for example. as numerals 2, 3, r and 5 which are progressively arranged from left to right and each of which appears back of the corresponding tabulator key. These column selecting indices are arranged in the hack of the first four tabulator keys from the left, in the present instance.
  • a perforated ear 103 is formed on the plate 98 and to which is pivoted, at 104. a link 105. The lower end of this link is pivoted, at 106, to the projection 90 on the arm 83. From an inspection of Fig. 1 it will be understood that when the arresting device is in the normal position the index plate 98 is maintained in the elevated position.
  • the arresting device When, however, the arresting device is moved to the operative position shown in l igs. 3 and 4, the index plate 98 will be swung down to cover the denominational indices and to expose the column selecting indices 102 to the view of the operator.
  • This change in the position of the index plate 98 is automatically eflected by the operation of the key 87 or 88 by which the arresting means are controlled, a depression of either one of these keys moving the plate 98 from the position shown in Fig. 1 to that indicated in Figs. 3 and 4.
  • each tabulator key has a full stroke, and is capable of projecting the corresponding denominational stop 29 to the farthest position to which it may be moved, as is indicated in Fig. 3. Therefore, any project-ed denominational stop will be moved into the path of all of the graduated column stops (37, (38, (39 and and the carriage will be arrested by first one and then the next of these column stops coacting with the projected denominational stops as in the ordinary Gorin tabulator. Should, however. the operator desire to use the tabulator mechanism for column selection, it is merely necessary to depress either the key 87 or the key thus bringing the arresting device into operative position. as shown in Figs. 3 and 4. and to actuate any of the.
  • first four keys from the left in accordance with the particular column to be selected. It will be understood that if the carriage is in its extreme right-hand position it will be in a position to write within the first columnar field. Therefore. an actuation of the firstkey 34 from the left for columnar selection will project the corresponding stop 29 into the path of the column stop 67. This will arrest the carriage at the beginning of the second column defined by the space between the two stops 6? and (18. If, for example, the operator desires to arrest the carriage in position to write within the fourth column, it is merely necessary to actuate the tabulator key 34. indicated by the index numeral 4. The corresponding stop '29 will be projected forwardly until it is brought into the path of the graduated stop 69.
  • the first set of stops being operative during the first half of the travel of the carriage. for example. and the second set being operative during the second half of the travel of the carriage.
  • the arresting. means may be graduated accordingly up to the full number of the ten tabulator keys emploved, each key effecting adifl'erent extent of movement to its, key controlled stop 29 under the control of the arresting means.
  • a corresponding number of graduated column stops should likewise be employed.
  • the selection of, say, five columns in the travel of the carriage is deemed sutlicient and I have accordingly shown the mechanism so constructed as to attain this result.
  • the column stop bar may be turned to present the column stops 71 for cooperation with the denominational stops when the latter are being used for denominational selection. This set of stops 71 may be availed of whenever denominational selection is desired but particularly when a larger number of column stops is to be employed than is provided for by the graduated column stops (37, G8, etc.
  • said column stops may be set in the following manner: Place a work sheet on the machine and adjust the carriage to the point where the second column is to begin. Then project the first of the denominational stops from the left and adjust the column stop 67 so as to engage it. Next adjust the carriage to begin the third column, project the second denominational stop from the left and adjust the column stop 68 so asto engage it, and so on with the other two column stops 69' and 70. In this manner the differences in the positions of the key controlled stops 29 when operating as column selecting stops will be automatically compensated for and the carriag'e will beproperly arrested in the desired columnar fields.
  • These arms project rearwardly from the arresting device and extend beneath the universal release bar, and beneath a member or interponent which is designated as a whole by the reference numeral 110.
  • This interponent extends longitudinally of the universal release bar and is provided with bearing slots 111 in the ends.
  • the interponent is thus supported by and movable with the universal release bar, and is also adapted to slide upwardly on the bearing screws 112 to a position where it may be interposed in the path of the collars 38 on the second, third and fourth denominational push rods 30 from the left.
  • the interponent 110 is slotted at 113 to enable it to be moved upwardly into the paths of the collars 38 without being interfered with by the push rods.
  • Graduated contact faces 114, 115 and 116 are provided on the interponent for cooperation with the associated contact devices or collars'38, when the interponent is in the elevated or operative position, between the universal release bar and said collars. From an inspection of Fig.
  • the carriage release mechanism will be variably actuated by the operation of the first four tabulator keys in accordance with the variation in the extent of movement of said keys relatively to each other. Therefore, the carriage will always be released at the last portion of the movement of each key, whether the keys are operating as denominational selecting keys or as column selecting keys, and notwithstanding that there is a variation in the extent of movement of said keys under different conditions. From what has been said it will be understood that the interponent is normally maintained by gravity in the lowermost position, shown in Figs. 11 and 12, where the collars 38 cannot be brought into cooperation therewith.

TYPE-WRITING MACHINE.
Specification of Letters Patent. Patented Sept. 21, 1915.
Application filed March 6, 1915. I Serial No. 12,511.
Z '0 all whom it may concern:
Be it known that I, CHARLES E. SMITH, citizen of the United States, and resident of the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certainnew and useful Improvements in Type-\Vrltmg Machines, of which the following is a specification.
My invention relates to typewritmg machines and more particularly to tabulator mechanism. Y
The objects of the invention, generally stated, are as follows: (1st) to provide a simple and eflicient tabulating mechanism capable of a wide range of use; (2nd) to provide an improved column selecting and denominational selecting mechanism; (3rd) to provide an improved tabulator construction which may, at will, be employed only as a column selector or only as a denominational selector; (4th) to provide an improved tabulating mechanism in which the same tabulating keys may be used indefinitely only as column selecting keys or only as denominational selecting keys as may be desired; (5th) to provide a simple and efficient construction in which any one of a large number of columns may be selected without adding to the number of tabulator keys ordinarily employed; (6th) to provide means by which the tabulator mechanism may be variably limited with reference one to another for column selection or may have a uniform limit of movement for denominational selection as may be desired; (7th) to provide means whereby denominational selecting mechanism employed in ma chines now on the market may be readily converted into tabulator mechanism which, at will, may be used for column selection or for denominational selection; (8th) to provide for the tabulator keys, tabulator indicating means which are automatically varied accordingly as the keys are used for column selection or for denominational selection; and (9th) to provide a construction whereby the above mentioned ends may be attained with the aid of devices which are in the nature of attachments that may be embodied in existing forms of typewriting machines and tabulating mechanisms To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations. of devices set forth in the following description and par-' ticularly pointed out in the appended claims.
In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a vertical fore and aft sectional View of one form of typewriting machine embodying my invention, the section being taken approximately on the line *w'w of Fig. 2 and looking in the direction of the arrows at said line.

Fig. 8 is a detail fragmentary perspective view of the tabulator indicating means. Fig. 9 is an enlarged detail sectional view of the column stop bar and some of the associated parts, the section being taken on the line rcm of Fig. 2 and looking in the direction of the arrows at said line. Fig. 10 is a fragmentary top plan view, partly in section, of a portion of the modified form of the tabulator mechanism. Fig. 11 is a transverse vertical sectional view of the same taken on the line y of Fig. 10 and looking in the direction of the arrows at said line. Fig. 12 is a fragmentary detail side elevation of the parts represented in Figs. 10 and 11.
Inthe various views parts of the machine are omitted, only so much of the machine being shown as may be necessary to arrive at an understanding of the invention.
In the present instance I have shown my invention embodied in a No. 11 Remington machine, the tabulator mechanism of which may. with the aid of my invention, be readily converted into a column selector without detracting from the use of the tabulator-as a denominational selector and without modifying or materially modifying, the structural features of said machine and tabulator mechanism as they now exist.
The frame of the machine comprises a base 1. corner posts 2 and a top plate 3. A carriage, designated as a whole by the reference numeral 4, comprises front and rear guide rails 5 and (3, res 'iectively, which are grooved to receive anti-friction balls or rollers 7, the latter being likewise received in oppositely grooved fixed guide rails S and 9. The carriage is thus supported to travel from side to side of the machine over the top plate. being propelled in the direction of its feed by a spring drum 10 to which one end of a strap or band 11 is nnected. the other end of said spring being connected to a bracket arm 12 secured to the carriage. A platen 13 is carried by the carriage for cooperation with upwardly and rearwardly striking type bars 14; The. rear cross bar or guide rail 6 of the carriage is provided with upwardly extending lugs 15, to which rearwardly projecting arms 16 are pivoted at 17. The rear ends of these arms are connected to a feed rack 18 which cooperates with a feed pinion 19. the latter being fixed to an escapement shaft that turns in a bearing 20, secured to the top plate of the machine. The rear end of the escapement shaft carries a double escapement wheel 21 which co-acts, in the usual manner, with the, feed dog controlled by the printing keys. Bracket arms 22 are secured by screws 23 to the rear cross bar 6 of the carriage. and support a column stop bar 24 on which column stops are adj ustably mounted.
A tabulator frame is fixed to the frame of the machine by screws 26 and pivotally supports, at 27, a series of denominational stop levers 28. The upper ends of these stop levers extend forwardly to provide the usual denominational stops 29 which comet with the column stops, it being understood that the denominational stops are spaced apart at letter space intervals. The lower ends of the stop levers 28 are pivotally connected to push rods 30. These push rodsextend to the front of the machine through guide. openings 31 (see Fig. 7) .in a casting 32, the casting being detac'hably secured to the frame of the machine in the usual manner. by screws 33. The forward ends of the push rods are provided with the usual finger buttons or keys 3%. In the present instance there are ten keys. push rods and stops, this being the usual number employed in the No. 11 Remington machine. Each push rod 30 carries the usual collar 35 adjustably secured thereto by a set screw 36. A contractile spring 37 is provided for each push rod, one
end of the spring being secured to the set screw 36 of the associated collar, and the other end of said spring being secured to the casting 32 in the usual manner. Each push rod 30 is also provided with the usual collar or contact device 38, adjustably secured to the rod by a set screw 39. Each of these collars 38 is adapted to co-act with a slotted universal release inn-'40. formed with arms 41 at the ends thereof. These arms are provided with hubs 42. threaded to receive set screws 43 bv which the arms are secured to a rock shaft 44. The. rock shaft is adapted to turn on pivot screws carried by the base of the machine. Each of the arms -'ll is also provided with a rearwardly extending depending member 45, to which is pivotally connected a rearwardly extending link 46. The rear end of each link 46 is connected t :1 depending crank arm -17, secured to a rock shaft 48which is adapted to turn on hearing screws in the base of the machine. A contractile returning spring 49 is connected at one end to an arm 47, and at its opposite end to a fixed cross bar 50. The rock shaft 48 also has fixedly secured thereto an arm 51, which extends down\\'ardl and then forwardly and upwardly for connection with a link 52. The link in turn is connected at its upper end to a carriage release lever 53. This release lever is pivoted at 54 above the top plate of the machine to a bracket 55 secured to the top plate. The forward end of=the release lever carries a sh e 56, which is located beneath the feed rack 18. From an inspection of Fig. 3 it will be understood that an actuation of the tabulator key 34 is effective to project the corresponding denominationalstop forward into the path of the column stop on the carriage. By the same operation of the tabulator key the universal release bar will be moved rearwardlv, as indicated in Fig. 3. thus transmitting motion to the carriage release lever through the intermediate connections between said universal release bar and the lever, thereby lifting the rack 18 and freeing the carriage for movementin the direction of its feed.
The usual or any desired denominational indices a'ii' are carried by the casting 2, each of said indices being directly behind and in register with the corresponding tabulator key which it is intended to designate.
The mechanism :13 thus far described constitutes part of the ordinary No. 11 Remington machine and needs no further description.
- In order that this denominational mechanism may be converted at will into a column selecting tabulator, I have provided devices which are in the nature of attachments that may be readily applied to the ordinary No. 11 Remington machine without modifying, or materially modifying, the structural features of said machine as they now exist. In some No. 11 Remington machines it is means common to provide a column stop bar corresponding to the column stop bar 24 which may be turned in its bearings to present either one of two oppositely projecting sets of colunm stops into position for cotiperation with the denominational stops 29. In the present instance, in order to accomplish this result, I have provided at one end of the column stop bar a pivot 58 seated in a bearing opening in the left-hand supporting bracket 22 so as to support the bar for turning movement. From an inspection of Figs. 2 and 8 it will be observed that the other end of the column stop bar has a cylindrical bearing portion 59, which is received in a corresponding bearing opening in the right-hand supporting bracket 22. This end of the column stop bar is reduced at 60, to receive a finger piece 61 fixedly secured to the column stop bar by a nut 62, the latter being received on the threaded end of the reduced portion 60. The cylindrical bearing portion 59 of the column stop bar is flattened on opposite. sides thereof, as indicated at 63, for eoiiperation with the flat end of a pin 64, in order to lock the? column stop bar against accidental displacement from either one of two positions to which it may be turned and in which one Or another set of column stops is presented in position for cotiperation with the key controlled stops 29. The pin 64 is riveted, or otherwise secured, to a leaf spring 65 secured, at 66, to the right-hand bracket 22. The pin 64 is received and adapted to work in an opening formed in the bearing portion of this bracket, in order to co-act with the flattened portions 63 of the column stop bar as hereinbefore pointed out. In the present instance I have shown two sets of column stops, one set of graduated column stops 67, 68, 69 and 70 which project varying distances from the column stop bar. The other set of column stops 71 project a uniform distance from the opposite side of the column stop bar. I preferably provide each of the column stops with a slight projection 71, as shown in Fig. 6, so as to prevent the column stop from being accidentally displaced from the bar.
In order to variably limit the extent of movement of the stops 29 relatively one to another, I have provided the following devices which are in the nature of attachments: Bracket plates72 and 73 are secured to the ends of the casting 32 by means of screws 74. An arresting member, designated as a whole by the reference numeral 75, comprises, in the present instance, a sheet metal frame formed as a cross bar 76 which extends across the machine beneath the tabulator push rods 30, and in the rear of the collars 35 thereon. This cross bar has a forwardly bent portion 77 provided '6 with stepped contact faces 78, 79, 80 and 81 which from left to right are at progressively greater distances from the cross bar 76, and toward'the front of the machine. The, arresting member, or frame, has arms 82 and 83 formed at the ends thereof and bent forwardly and pivoted on shouldered pivot screws 84 to the bracket plates 72 and 73. The pivotal movement of the arresting member is limited by stops 85 which are carried by and project to the right from the lefthand bracket plate 73. A contractile spring 86 is connected at one end to the bracket plate 73 and at its opposite end to the arm 83 forward of its pivot, the spring tending to normally maintain the arresting device in the position shown in Fig. l. The'arm 83 extends forwardly and is provided with a finger key 87 by which the arresting member may be moved from the normal position shown in Fig. 1. the stops or contact faces 7 8, 79, etc.', are out of the paths of the corresponding collars or stops 35 on the push rods 30. When, however, the key 87 is depressed, the arresting member will be moved from the position shown in Fig. 1, to that-indicated in Figs. 3 and 4, where the contact faces 78, 79, etc., are in the paths of the corresponding stops or collars on the push rods, to variably limit the movements of the corresponding push rods relatively to each other. In order to maintain indefinitely the arresting member in its effective or operative position, shown in Figs. 3 and 4, I have provided locking means comprising an independently operable locking key 88, pivoted at one side of its center, at 89, to an upwardly projecting arm 90, on the arm 83. The locking key 88 has a depending portion 91 provided with a hook-like engaging portion 92 which is adapted to engage under a companion engaging projection or nose 93, formed on the bracket plate 73, as indicated in Fig. 4. A coiled spring 94 surrounds the pivot 89 and bears at one end against the depending portion 91 of the key 88, the opposite end 95 of said spring engaging a projection 96 on the part 90. The force of the spring is thus applied to normally maintain the key 88 in the position shown in Fig. 3, relatively to the arm 83. A stop pin 97 is carried by the arm 83 and limits the movement of the key 88 around its pivot 89 back to normal position. A depression of the key 88 is effective to turn it around the pivot 89, against the pressure of the spring 94, and at the same time to move the arm 83 down, so as to bring the stop faces or cross bar 76 of the arresting member into the path of the stops or collars 35 on the push rods. When the parts have reached the limits of their movements the engaging nose 93 will 'be forced under the engaging portion 92 of the bracket 73, thus locking the parts in the actuated position, as indicated in Fig.
In the normal position 4. They may be retained indefinitely in this position until pressure is exerted on the linger key ST. which is etl'cctive to release the engagementbetween the parts 92 and 93, thus enabling the spring 9+ to return the key So to its normal position relatively to the arm 83. The arresting device will thus he released and the spring 8!) is eli'ective to return it to normal or inoperative position. It will be understod that when the arrestin member is in the position shown in Figs. 3 and l the tabulator mechanism is operative for column selection only as will hereinafter more clearly appear. whereas, when the arresting member is in the normal or inoperative position, shown in Fig. 1, the tabulator mechanism is operative only for denominational selection.
In order that the operator may not be confused as to the character of selection that the tabulator is set to effect, and in order to provide appropriate indices for both characters of selection. '1'. 0., denominational selection and column selection, I have provided means for autolmitically changing the tabulator indices in accordance with the character of selection that the mechanism is operative to effect. Thus, in addition to the denominational indices 57 already described, I have provided a plate 98 which. as is best shown in Fig. 7, is turned at one edge. as at 99, to provide seats for pivot pins 100, which pins are likewise received in bearing openings in upwardly projecting arms 101 on the plate-like brackets 72 and 73. The upper side of the index plate 98 is inscribed with column selecting indices 10"), such for example. as numerals 2, 3, r and 5 which are progressively arranged from left to right and each of which appears back of the corresponding tabulator key. These column selecting indices are arranged in the hack of the first four tabulator keys from the left, in the present instance. A perforated ear 103 is formed on the plate 98 and to which is pivoted, at 104. a link 105. The lower end of this link is pivoted, at 106, to the projection 90 on the arm 83. From an inspection of Fig. 1 it will be understood that when the arresting device is in the normal position the index plate 98 is maintained in the elevated position. thus exposing the denominational indices 57, as shown in Fig. the column selecting indices at this time being hidden from the view of the operator. When, however, the arresting device is moved to the operative position shown in l igs. 3 and 4, the index plate 98 will be swung down to cover the denominational indices and to expose the column selecting indices 102 to the view of the operator. This change in the position of the index plate 98 is automatically eflected by the operation of the key 87 or 88 by which the arresting means are controlled, a depression of either one of these keys moving the plate 98 from the position shown in Fig. 1 to that indicated in Figs. 3 and 4.
1n the operation of the machine for de nominational selection each tabulator key has a full stroke, and is capable of projecting the corresponding denominational stop 29 to the farthest position to which it may be moved, as is indicated in Fig. 3. Therefore, any project-ed denominational stop will be moved into the path of all of the graduated column stops (37, (38, (39 and and the carriage will be arrested by first one and then the next of these column stops coacting with the projected denominational stops as in the ordinary Gorin tabulator. Should, however. the operator desire to use the tabulator mechanism for column selection, it is merely necessary to depress either the key 87 or the key thus bringing the arresting device into operative position. as shown in Figs. 3 and 4. and to actuate any of the. first four keys from the left, in accordance with the particular column to be selected. It will be understood that if the carriage is in its extreme right-hand position it will be in a position to write within the first columnar field. Therefore. an actuation of the firstkey 34 from the left for columnar selection will project the corresponding stop 29 into the path of the column stop 67. This will arrest the carriage at the beginning of the second column defined by the space between the two stops 6? and (18. If, for example, the operator desires to arrest the carriage in position to write within the fourth column, it is merely necessary to actuate the tabulator key 34. indicated by the index numeral 4. The corresponding stop '29 will be projected forwardly until it is brought into the path of the graduated stop 69. the extent of movement of the key actuated stop being determined by the collar on the associated push rod engaging the stepped stop on the arresting device. The extent of movement thus transmitted to the actuated stop 29. is insuflicient to move it into the path of either the stop 67 or 68, so that the carriage will, when released, move to the left until arrested by the cooperation of the column t p 69 with the projected denominational stop controlled by the third tabulator key from the left. So on in this manner each of the columns within the range of the tabulator may be selected. It will be understood that if desired a second series of four graduated column stops'correspondin s to the stops 67, 68, 69 and 7 0 may be employed. the first set of stops being operative during the first half of the travel of the carriage. for example. and the second set being operative during the second half of the travel of the carriage. In this manner provision is made for a column selection within a range of nine columns with the mechanism shown and described. If it is desired to provide for selecting even a greater number of columns, the arresting. means may be graduated accordingly up to the full number of the ten tabulator keys emploved, each key effecting adifl'erent extent of movement to its, key controlled stop 29 under the control of the arresting means. Of course, a corresponding number of graduated column stops should likewise be employed. However, in most instances the selection of, say, five columns in the travel of the carriage is deemed sutlicient and I have accordingly shown the mechanism so constructed as to attain this result.
It may be found sufficient 1n some instances to adjust the first four of the collars 38 from the left, as indicated in Figs. 1 and 2, so that they will take up the universal release bar at different times, depending on the extent of movements to be transmitted to the first four tabulator keys from the left when the latter are operating as column selecting keys. This insures a proper actuation of the carriage release by the different variably movable tabulator keys when they are operating as column selecting keys, and will not so materially afiect the proper release of the carriage when these same keys are operating as denominational selecting keys as to render the mechanism inefiicient or ineffective. It will be understood that in each instance the second, third and fourth'of the tabulator keys from the left, when operating as denominational selecting keys, will take up the universal release bar at a slightly earlier period than the remaining keys will. But inasmuch as the graduated stops 67, 68, 69 and extend rearwardly greater distances than the stop 67, and inasmuch as the key controlled stops at this time move to their greatest extent, there will be little or no liability of the carriage skipping. If desired, however, the column stop bar may be turned to present the column stops 71 for cooperation with the denominational stops when the latter are being used for denominational selection. This set of stops 71 may be availed of whenever denominational selection is desired but particularly when a larger number of column stops is to be employed than is provided for by the graduated column stops (37, G8, etc.
In order to compensate for the distance of four letter spaces which separates the first and fourth denominational stops 29, when the latter are cooperating with the graduated column stops for column selection, said column stops may be set in the following manner: Place a work sheet on the machine and adjust the carriage to the point where the second column is to begin. Then project the first of the denominational stops from the left and adjust the column stop 67 so as to engage it. Next adjust the carriage to begin the third column, project the second denominational stop from the left and adjust the column stop 68 so asto engage it, and so on with the other two column stops 69' and 70. In this manner the differences in the positions of the key controlled stops 29 when operating as column selecting stops will be automatically compensated for and the carriag'e will beproperly arrested in the desired columnar fields.
While the actuation of the universal release bar by the differently adjusted contact devices or collars 38 may be provided for as hereinbefore described, it may be found con venient and desirable in some instances to provide means for automatically varying the release of the carriage according to the variation in the arrest of the push rods relatively to each other, for column selection. I have shown in Figs. 10, 11 and 12 means whereby such automatic variation in the release may be effected. In these views the parts which correspond to those hereinbefore described will be referred to by the same reference numerals. It will be seen from these figures that I have provided two rearwardly extending arms 10?. which are connected by a cross bar 108, that is secured by screws 109, to the cross bar 76 of the ar resting device. These arms project rearwardly from the arresting device and extend beneath the universal release bar, and beneath a member or interponent which is designated as a whole by the reference numeral 110. This interponent extends longitudinally of the universal release bar and is provided with bearing slots 111 in the ends.
openings in the universal release bar 40."
The interponent is thus supported by and movable with the universal release bar, and is also adapted to slide upwardly on the bearing screws 112 to a position where it may be interposed in the path of the collars 38 on the second, third and fourth denominational push rods 30 from the left. The interponent 110 is slotted at 113 to enable it to be moved upwardly into the paths of the collars 38 without being interfered with by the push rods. Graduated contact faces 114, 115 and 116 are provided on the interponent for cooperation with the associated contact devices or collars'38, when the interponent is in the elevated or operative position, between the universal release bar and said collars. From an inspection of Fig. 10 it will be understood that there is practically no lost motion between the sleeve 38 on the push rod of the fourth tabulator key from the left and its associated contact" face 116, so that the universal bar will be taken up at key to give said universal release bar the fullest extent of movement. On the other hand, the collar 38 of the first key from the left has the longest extent of lost motion before it engages the universal release bar. The other intermediate collars 38 co-act with their associated contact faces 114: and 115, on the interponent, at relatively different points in the strokes of the keys. It will be understood therefore that when the interponent is in the elevated position and operative, the carriage release mechanism will be variably actuated by the operation of the first four tabulator keys in accordance with the variation in the extent of movement of said keys relatively to each other. Therefore, the carriage will always be released at the last portion of the movement of each key, whether the keys are operating as denominational selecting keys or as column selecting keys, and notwithstanding that there is a variation in the extent of movement of said keys under different conditions. From what has been said it will be understood that the interponent is normally maintained by gravity in the lowermost position, shown in Figs. 11 and 12, where the collars 38 cannot be brought into cooperation therewith. \Vhen, however, either of the keys 87 or 88 is depressed and the movement of the arresting device to operative position is effected, this results in elevating the arms 107 to lift the interponent into the path of the associated collars 38 on the push rods 30, so that motion to the carriage release mechanism is transmitted through the interponent to variably effect a release of the carriage in accordance with the variation in the arrest 01 the tabulator keys and stops which are employed for column selection.
From the foregoing description itwill be understood that I have provided simple, inexpensive and efficient means whereby denominational tabulating mechanisms and typewriting machines now employed on the market may be provided with devices which are in the nature of attachments that will enable said denominational selecting mechanism to be used as such. when desired, and will also enable the denominational tabulati ng mechanism to be readily converted into a column selector.
Various changes may be made without departing from the spirit and scope of my invention and certain of the devices herein disclosed may be employed without othersf 'hat I claim as new and desire to secure by Letters Patent. is
