CHARLES E. SMITH, OF NEW YORK, N. Y., ASSIGNOR TO REMINGTON TYPEWRITER COMPANY, OF ILION, NEW YORK, A CORPORATION OF NEW YORK.

TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Sept. 21, 1915.

Y '0 all 11:]: out 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 certain new and useful Improvements in Type-IVriting Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to tabulating mechanism.

The main object of my invention, generally stated, is to provide comparatively simple tabulator mechanism with the aid of which any desired column, or any desired denominational position within the desired column, may be readily selected by a single run of the carriage to the point of arrest, or in which denominational selection in successive columns may be effected.

A further obect of my invention is to provide means ofthe character specified which may be readily embodied in typewriting machines equipped with tabulator mech anism now employed on the market, and-without modifying, or materially modifying, the

structural features of such machines and tabulator mechanisms as they now exist.

To the above and other ends which will hereinafter appear, my invention consists of 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.

In the accompanying drawings wherein like reference numerals indicate corresponding parts of the different views, Figure 1 is a vertical fore and aft sectional view of one form of typewriting machines embodying my invention. the section being taken on the line of Fig. 4 and looking in the direction of the arrows at said line. Fig. 2 is a detail fragmentary perspective view of the column stop bar and some of the associated parts. Fig. 3 is a transverse sectional view of the same. the section being taken on the line I/, of Fig. 2 and looking in the direction of the arrow at said line. Fig. 4 is a fragmentary plan view of the machine with parts broken away and omitted. Fig. 5 is a skeleton view in side elevation of the tabulator mechanism, the view illustrating the parts in working positions. Fig. 6 is a detail diagrammatic perspective view of the arresting means for the tabulator actuating devices, and the means by which said members are controlled, the arresting bars being shown separated to better illustrate the construction. Fig. 7 is a transverse vertical sectional view showing these same members and some of the associated parts, the view being taken on the line zz of Fig. l and looking in the direction of the arrow at said line.

.In the various views I have illustrated only so much of the typewriting machine as may be'necessai'y to arrive at an understanding of my invention.

In the present instance I have shown my invention embodied in a No. 11 Remington machine in which devices of my invention in the nature of attachments may be readily incorporated without modifying, or materially modifying, the structural features of said machine as they now exist. By this em bodiment of my invention I am enabled to.

convert the ordinary tabulato-r of the Gorin type, and in which denominational positions in successive columns may be selected, into a tabulator in which column selection, or combined column and denominational selection at a single run of the carriage, may be effected. Vhile I have shown my invention included in a No. 11 Remington machine with the results stated, it should be understood that the invention may be embodied in other styles of machines.

From certain aspects there are features of the present invention which are similar to some of those disclosed in an application. Serial No. 12,511 filed by me March 6, 1915, and there are claims in said previously filed application which cover the present construction. The claims in this case are restricted to features not disclosed in the earlier filed application. 7

The frame of the machine comprises a base 1, corner posts 2 and a top plate 3. A carriage comprising end bars 1, a rear cross bar 5 and a front cross bar 6, is mounted for movemcnt from side to side of the machine over the top plate. Thus the front cross bar 6 of the carriage isgrooved at 7 to receive anti-friction balls or rollers S which are likewise received in an oppositely grooved fixed guide rail 9. The rear cross bar 5 of the carriage is grooved at 10 to receive anti-friction balls or rollers 11 which are likewise received in an oppositely grooved fixed guide rail 12. A' cylindrical platen 13 is carried by the carriage and upwardly and rearwardly striking type bars 14 impact against the front face of the platen. A spring drum 15 is connected by a band 16 to a bracket 17 secured to the carriage at the right-hand end thereof. This drum propels the carriage from right to left under con trol of the usual step-by-step or letter feed mechanism, and also propels the carriage when it is released from the control of its escapement mechanism, as for example,when the tabulator mechanism is actuated. A feed rack 18 is carried by arms 19 pivoted at 20 to the rear cross bar 5 of the carriage. The feed rack engages a feed pinion 21 secured to the forward end of an escapement wheel shaft which turns in a fixed bearing 22 secured to the top plate of the machine. The rear end of the escapement wheel shaft carries a double escapement wheel 23 which co-acts with the key controlled escapement dog in the usual manner. A shoe24 extends beneath the feed rack 18 and is carried by a release lever 25 pivoted at 26 to a bracket on the top plate of the machine. The rear end of the release lever is connected to a downwardly extending link 27, which latter is connected at its lower end to an arm 28 fixed to a rock shaft 29 which is pivoted at its ends in the base of the machine. This rock shaft carries depending crank arms 30 which are connected to links 31. The forward ends of these links are connected to ears 32 on depending arms 33 which carry a universal release bar and which are supported on a rock shaft 34. It will be understood that an actuation of the universal release bar on the operation of the tabulator is effective to transmit movement through the links 31, crank arms 30, arms 28, link 27 and release lever 25 to effect a lifting of the rack from engagement with the feed pinion 21, thus releasing the carriage from control of the escapement mechanism. Springs 30 return the carriage releasing devices to normal position.

Rearwardly extending bracket arms 35 are secured to the rear cross bar 5 of the car.- riage and support at their rear ends a column stop bar 36. This column stop bar is provided with teeth on opposite sides thereof for the reception of plate-like bifurcated column stops in the interdental spaces in said bar. Denominational stops 37 are formed on the upper forwardly projecting ends of denominational stop levers 38 which are pivoted at 39 to a tabulator frame 40 secured to the frame of the machine by screws 41. The denominational stops are spaced apart at letter space intervals in the usual manner, and are adapted to be projected into the path of column stops carried by the column stop bar. Thus the lower ends of the denominational stop levers 38 are connected to push rods 42 which extend forwardly to the front of the machine where they are provided with tabulator keys 43.

These rods extend through bearing openings in a guide member 44 secured by screws 45 to the base of the machine at the front thereof. Contractile springs 46 are connected at their forward ends to a member 47 secured to the guide member 44. The rear ends of said springs are secured to their respective push rods by screws 48. These screws are received in tapped openings in collars 49 and are adapted to bear at their inner ends against the push rods in order to secure the collars in the positions to which they may be adjusted along the push rods. Adjustable collars or contact devices 50 are likewise adjustably secured on the stop rods by set screws 51 and are adapted to co-act,

with the universal release bar to effect a rearward movement of the same and thereby operate the carriage releasing means to lift the feed rack and release the carriage from control of its escapement mechanism. The guide member 44 is provided on its upper inclined face with denominational indices 52 which are in register with the respective tabulator keys 43 which they are intended to designate.

The parts as thus far described, constitute part of the ordinary equipment of the No. 11 Remington machine and further description thereof is deemed unnecessary.

In the No. 11 Remington machine the denominational stops are always projected forwardly the same distance in the path of the column stops. By my present invention I provide regulating means whereby all of the denominational stops may be projected a uniform distance at one time and a uniform distance of a different extent at another time. In this manner the denominational stops may be brought into cooperation with column stops which project variable distances from the column stop bar, and thus bring about an arrest of the carriage after a single run at any desired column and at any desired denominational position within the selected column. I also provide means whereby the carriage release mechanism may be variably effected in accordance with the variation in the throw of the denominational stops.

The arresting means referred to above consist, in the present instance, of a plurality of stops or arresting bars or

members

53, 54, 55, 56. The bar 53 is fixed by screws 57 to bracket arms 58, which latter in turn are secured by screws 59 to a part 60 fixed to the base of the machine. The arresting bar 53 is slotted at 61 for the free passage therethrough of the actuating devices or tabulator push rods 42, and likewise for the free passage thereth-rough of auxiliary push rods or

actuating devices

62, 63, 64 and 65. There may be any suitable number of these auxiliary push rods in accordance with the number of columns to be selected. In the present instance I have shown four such push rods, each provided with a key 66 arranged beneath one of the tabulator keys 43. Contractile springs 67 are connected at their forward ends to a supplemental plate 68 which is secured to the usual guide 44. The rear end of each spring is connected to the associated auxiliary push rod by means of a screw 69. From an inspection of Figs. 1, 4 and 6 it will be observed that these

push rods

62, 63, 64 and 65 are arranged from left to right beginning beneath the left-hand end of the series of push rods 42 so that each key 66 is arranged directly beneath a key 43. Moreover, it will be observed that each of the

push rods

63, 64 and 65 is provided with an upwardly projecting cam 70 formed with an inclined face 71 and a dwell 72. It will likewise be observed that the rod 62 is devoid of any such cam. -These rods pass freely through openings 61 in the member 53 and through the openings 73 in the various arresting members or bars 54, 55 and 56. Each of said arresting bars, with the exception of the fixed bar 53, is supported for vertical movement by a pair of links 74, each link extending outwardly from an end portion of the associated arresting bar. Each link 74 is pivoted on a shouldered pivot screw 75 to the body portion of its associated arresting bar. The opposite end of each link is pivoted to turn on the axis of a shouldered pivot screw 76 threaded into the link and turning freely in a bearing opening in an arm 77 of a bracket 78. These brackets are secured by screws 79 to the forward face of the fixed arresting bar or member 53. The arms 77 on each bracket have a stepped shape arrangement, as indicated in Fig. 4 in order to bring them into different planes substantially coin cident with 'the planes of the associated arresting bars which are supported thereby through the intermediate links. It will be understood that there is sufiicient lost motion at the points of pivotal connection of the links to prevent a buckling of the parts, thus enabling the movable arresting bars to be freely elevated to their operative positions, as will hereinafter more clearly apear. From an inspection more particularly of Fig. 6, it will be seen that each cam 70 is cotiperative with one of the arresting members or bars to lift it to operative position and is ineffective on the other bars. For example, the cam 70 on the push rod 63 is of the member 54 to elevate this member to the operative position. On the other hand, the

members

54 and 56 have openings 80 alined with the cam on the push rod 54, whereas the member 55 has a closed portion 81 with which said cam is adapted to be brought into coiiperation to elevate the arresting member 55. The cam on the push rod 65 co-acts with a closed portion 81 on the member 56 to lift this first of the arrestmg members, the second and

third members

55 and 54 respectively being provided with slots 80 to permit the cam to pass freely therethrough. The last arresting bar 53 is, as before pointed out, slotted at 61 so that all of the cams 70 may pass freely through or into said slots.

In Fig. 5 I have illustrated the push rod 64 1n the actuated position, thus efi'ecting an elevation of the arresting member and allowing the arresting

members

54 and 56 to remain in the lowermost or normal position. From an inspection of this figure it will be. understood that a movement of the push rod 64 to its operative position, as indicated in this figure, is effective to elevate the arresting member and bring it into the path of all of the collars or stops 49 on the push rods 42, thereby arresting the rearward movement of any or all OIESHId push rods and the denominational stops 37 controlled thereby. The effect of the arresting mechanism described is, as stated, to limit the extents of forward movement of the denominational stops and thus bring them into the paths of different column stops. Thus I have shown, in the present instance, four column stops 82, 83, S4, 85 which project rearwardly different distances from the column stop bar 36. The finger keys 66 on the

push rods

62, 63, 64 and 65 may be numbered progressively from left to right on the heads thereof 1, 2, 3. and 4. As heretofore explained the push rod 62 is devoid of a cam 70 so that the actuation of this push rod is ineffective on any of the arresting bars or members. This being the case, the tabulator keys 43 may be moved rearwardly their greatest extent, or until they are arrested by the collars or stops 49 co-acting with the fixed arresting bar or member 53. This is effective to project the actuated denominational stop into the path of the shortest column stop 82 arranged at the left-hand end of the series, thereby arresting the carriage at the first columnar field, and in the desired denominational position within this field as determined by the particulartabulator key 43 which has been actuated. Should the operator desire to arrest the carriage at, say, the hundreds position in the fourth column, it is merely necessary to first push rearwardly the key bearing the index numeral 4, thus elevating the arresting bar 56 which is farthest forward and bringing it into the path of the stops 49 on the tabulator push rods. The operator may then push the hundreds key rearwardly, projecting the corresponding denominational stop into the path of the fourth column stop 85, counting from left to right, and the carriage will be arrested after a single run in the fourth columnar field and in the hundreds position within that field. Should the operator desire merely to column select, the desired selecting key 66, say, the one bearing the index numeral 3, should be pushed rearwardly, then an actuation of the last of the series'of tabulator keys 43 opposite the 1,000,000 point will be effective to release the carriage and bring about an arrest thereof for writing within the third columnar field. Vhere wide columns are used and it is desired merely to column select and to bring about an arrest of the carriage so as to begin writing near the left-hand side of each column on the paper, the operation would be as follows :Each column stop is set so as to begin a column when the decimal stop coacts therewith, the proper selecting key 66 isactuated and then the decimal key is operated. Thus, should the operator desire to begin writing in the third column beginning at, say, 45 on the scale, the column stop 84 having been set at 45 on the stop rod, an actuation of the column selecting key 66 bearing the index ,numeral 3 will be effected and the decimal key will then be operated. This will bring about an arrest so as to begin writing at the first part of the third column.

It will be observed that each of the arresting

members

54, 55 and 56 is provided with notches or recesses 86, each arranged beneath one of the tabulator push rods 42. This is in order that the collars or stops 49 may be brought into efiective engagement with the arresting members when the latter are elevated tothe arresting position, as indicated in Fig. In order to provide an effective bearing for the arresting plates, one against another, when they are in the elevated positions, and to prevent a teetering of the plates through the pressure of the contact devices 50 thereon, I preferably provide upwardly extending lugs 87 on the

plates

54 and 55, these lugs being of the same thickness as the plates themselves. Thus, the lugs 87 on the plate 54 will constitute a bearing for the plate 55 when the latter is in the elevated position, and will resist a. rearward pressure on said plate at a height which corresponds substantially to the height of the contact devices 49. On the other hand, the lugs 87 on the plate 55 will resist a rearward pressure exerted against the plate or arresting member 56. It will be understood, of course, that ultimately the rearward pressure exerted by the contact devices or stops 49 is resisted by .to avoid confusion in the showing.

the fixed arresting member 53. I have eliminated these bearing lugs 87 in Figs. 1 and 5 It will be understood, moreover, that in Fig. 4 the first four tabulator keys 43, counting from left to right, together with the forward end portions of the push rods which carry them, have been omitted in order to disclose the selecting key 66 and'the push

rods

62, 63, 64 and 65 which .are arranged beneath the first mentioned push rod and keys. The

movable arresting members

54, 55 and 56 may be supported in the normal position by supporting pins 88 which project forwardly from the fixed arresting bar or member 53 and may be received in cut-outs or apertures 89 in the movable arresting members.

In the N0. ll Remington machine the collars 50 on the tabulator push rods constitute contact devices which co-act directly with a universal release bar 90 to effect an operation of the carriage releasing means when a tabulator key is actuated to project a denominational stop forward to operative po sition. In the present instance I have provided means whereby a variation in the timing of the release with reference to the operation of the tabulator push rod may be effected. These means correspond in construction to the arresting

members

53, 54, .35 and 56 except that thev are mounted on and movable with the universal bar instead of being carried by a fixed part of the machine, as is the case with the arresting means. Thus, I have provided three

members

91, 92, 93 which I term interponents and which, as hereinbefore stated, are constructed and mounted like the arresting members with which the stops 49 co-act. These interponents are mounted on links 94 which, like the links 74, are pivoted on brackets 95 secured in this instance to the universal release bar 90 and movable bodily therewith. in the movement of the latter around the pivotal axis of the rock shaft 34. Cams 96 are provided on the

push rods

63, 64 and 65 which co-act with the interponents to elevate them into the paths of the contact devices 50 on the push rods of the tabulator keys. The operation of the cams 96 on the interponents is similar to the operation of the cams 7 0 on the arresting members. Thus the cam 96 carried by the push rod 63 is effective to elevate the rear interponent 91 and bring it into the path of the contact devices 50 on the tabulator push rods 42, whereas an actuation of the push rod 64 is effective to elevate the second interponent 92 and bring it into the path of the contact devices 50. An actuation of the fourth column selecting key to move the push rod 65 rearwardly is ef fective to elevate the first interponent 93 and bring it into the path of the contact devices 50. On the other hand, an operation of the first selecting key carried by the push through the intermediate train of connec-- tions elevates the feed rack 18 in order to release the carriage. The operation of the interponents to correspond with the particular arresting member which is elevated is illustrated in Fig. 5. From this figure it will be seen that an actuation of the selecting key on the push-rod 64 is effective to elevate the second arresting member 55 and the second interponent 92. This view illustrates the parts as they appear after the selecting key on the push rod 04 has beenactuated, and after one of the denominational keys has been actuated. It will be seen that the tabulator key and the parts controlled thereby have been arrested and that the universal release bar has been operated to release the carriage from control of the escapement mechanism while the corresponding denominational stop has been projected into the path of the column stop 84, this latter being determined by the particular selecting key which has been operated.

From the foregoing description it will be understood that the universal release bar will be taken up and actuated sooner or later in the strokes of the tabulator keys, depending on the extent of movements which may be given said keys as determined by the arresting means. In this manner I have provided means for automatically varying the release of the carriage in accordance with the variation in the throw of the denominational stops, in order that the car riage may be properly released irrespective of the extent of throw given to the denominational stops. If for example a denominational stop receives its greatest extent of throw to bring it into the path of the column stop 82. then the carriage will not be released until the last portion of the movement of said denominational stop, and

through the cooperation of the contact device 50 directly with the universal release bar 90. On the other hand, if a denominational stop should receive its shortest extent of movement to bring it into the path of the column stop 85, then the associated contact device 50 will co-act with the interponent 93 and start to move the universal release bar at the first part of the movement of the tabulator key, thus effecting a release of the carriage by the time the projected denominational stop is in the path of the column stop 85.

Of course, it will be understood that by actuating the tabulator keys 43 in the ordinary manner without a prior actuation of the selecting keys, denominational selection in successive columns will be effected in the usual manner. At this time the denominatlonal stops would receive their greatest extent of throw, and would be brought into cooperation with any of the column stops 82, 83, 8st or 85 and no columnar selection would be effected. Moreover,-it will be understood that the release of the carriage would be properly timed for the use of the tabulator in this manner. It will also be understood that in these circumstances any number of column stops may be employed.

In order to facilitate the employment of a large number of column stops, if desired,

for ordinary work at one time and to pro vide for the use of a comparatively restricted number of column stops S2, 83, S4: and 85 of varying lengths for column selectlon at another time, I have provided a column stop bar which is adapted to be turned to bring either one or another of two sets of column stops into use, as is sometimes provided in the No. 11 Remington machine. In the present construction the col umn stop bar has bearing portions 97 at the ends thereof which are received in the bearings- 98 in the supporting arms 35 for the column stop bar. One of these bearing portions is flattened on opposite faces thereof, as indicated at 99, for cooperation with a flattened end of a spring pressed pin or detent 100. This detent may be connected by a rivet, or otherwise, to a. spring 101 secured at one end by a screw 102 to the associated bracket arm The pressure of the spring detent is exerted to retain the column stop bar in either of the two positions to which it may be rotated in its bearings to bring either the column stops S2, S3, 84:, S5 or the column stops 103, which project from the opposite side of the bar, into use. One end of the column stop bar extends beyond its bearing and is reduced at 101 (see Fig. 4) to receive a knurled finger piece 105 secured to the stop bar by a nut 10G.

\Vhile in the present instance I have shown the machine equipped for the selection of four columns, it should be understood that this number may be increased if desired by the provision of additional selecting keys 00. interponents and arresting devices and by dividing the full extent of throw of the denominational stops into a greater number of extent-s. one extent of movement being provided for each arresting device and interponent and selecting key employed. In such a case, of course. the thickness of the arresting members and interponents, as well as the extent of overlap of a denominational stopwith each of the column stops, will be decreased. Then again, without modifying the structure, one or more additional sets of column stops 82, 84, 85 may be employed, one set, say, for

affording a selection of any one of the first four columns in the firsthalf of the run of the carriage, and a second set for affording a selection of .any one of four columns during the second half of. the run of the carriage. In this manner or in the manner previously described, the selecting mechanism may be employed for the selection of a larger number of columns than is shown in the present instance, though for ordinary work the selection of any one of four columns has been found to be sufficient in practice.

It will be seen that I have provided simple and comparatively inexpensive devices, which are in the nature of attachments, that may be readily embodied in existing machines without modifying, or materially modifying, the structural features thereof, and with the aid of which ordinary tabulator mechanism'of the Gorin type may be readily converted into a combined column and denominational selector, for effecting an arrest of the carriage at any desired columnar field and at any desired denominational position within the selected field after a single run of the carriage. It will also be understood that, when desired, this tabulator mechanism may be used in the ordinary manner of a Gorin tabulator to effect denominational selections in successive columns or may, when desired, be used merely as a column selector.

Vhile I have shown and described with considerable particularity one form of construction embodying my invention I am aware that various changes may be made without departing from the spirit and scope of my invention.
