WILLIAM H. DENNING, OF SOUTH TOTTENHAM, LONDON, ENGLAND, ASSIGNOR TO UNION TYPEWRITER COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY.

TYPE-WRITING MACHINE.

Application filed December 11, 1906.

To all whom it may concern:

Be it known that I, WILLIAM H. DENNING, a subject of the King of Great Britain, and resident of South Tottenham, London, England, have invented certain new and useful Improvements in Type-Writing Machines, of which the followin is a specification.

My invention redates to typewriting machines and more particularly to tabulating mechanism and has for its object the provi sion of means whereby numbers or sets of numerals, for instance, may be differently pointed off or punctuated according to the character of the work to be written with the aid of the tabulating mechanism.

To the above and other ends which will be hereinafter described, my invention consists of the features of construction, arrangements of parts and combinations of devices to be described in the following specification and set forth in the accompanying claims.

In the drawings wherein like reference characters indicate corresponding parts in the various views-Figure 1 is a vertical, front to rear, central sectional View of a suiiicient number of parts of a type-writing machine to illustrate my invention in its application thereto. Fig. 2 is a detail fragmentary vertical sectional view showing one of the denominational stops, an associated spacing block and means for mounting the latter. Fig. 3 is a detail perspective View of a portion of the carriage feed mechanism. Fig. 4 is a detail vertical sectional view showing a portion of the carriage feed mechanism. Fig. 5 is a detail top plan view of the machine with parts broken away. Fig. 6 is a rear elevation of the machine with parts broken away. Fig. 7 is an enlarged detail horizontal sectional view of a portion of the tabulating mechanism, the view being taken on the line t-m of Fig.0 and looking in the direction of the arrow at said line. Fig. 8 is a detail perspective view of a justifying device which cooperates with the denominational stop actuating levers. Fig. 9 is a detail top plan view of one of the spacing devices; the actuating lever with which it is adapted to cooperate being shown in section, the section being taken on the line y-ay of Fig. 6 and looking in the direction of the arrow at said line.

I have shown my invention applied to a No. 10 Yost typewriting machine and in connection with tabulating mechanism re- Specification of Letters Patent.

tabulator, though it should be understood that the invention may be employed in various styles of typewriting machines and in connection with different forms of tabulating mechanism.

In tabulator work it is often necessary or desirable to point oil or punctuate differently according to the character of work to be produced. In some cases it may be necessary or convenient to write the numerals with the aid of the tabulator thus:1234567890, assuming the tabulator is a ten key orten stop tabulator or one capable of writing billions. Then, again, it may be necessary or desirable to point oil the number thus: 1,234,567,890. In writing sterling money it may be convenient or desirable to point oil the numbers so that pounds, shillings and pence will be properly divided thus:

3 8. d. 100,000- 19 10 or thusz- .8 s. d. 100,000 19 10 or thus a? s d I'Ieretofore when it was deemed necessary or desirable in, say, ten key or ten stop tabu lators to point ofl' thusz-l 334,567,890 it was necessary to change the index at the tabulator keys amordingly and to employ a tabulator key for each comma, punctuation mark, or space employed in pointing oll' thenumber. In the last example given it would be necessary to use three keys or stopsfor the commas between the numerals i and 2, 4 and 5 and 7 and 8 and one for the decimal )oint, so that even assuming that this could be done the scope of the tabulator would be reduced four stops. As a matter of fact, however, the operator could not in a ten key tabulator write a number higher than 9,999,999. instead of 0999990990 where the commas and decimal point or spaces required for punctuation are not employed. By my present invention the )ointing oil' of the numbers may be effected in any desired manner without reducing the rapaeity of the machine and the spacing required for ninetuating may be effected by the tabniating mechanism itself. If, for i1'istan-;'e, the invention is applied to a typewriting mai hine having a tabulaiorwhiehemploystentabulator ke 's or ten denominational stops, then ten numerals may be written with the aid of the tabulator and spaced according to the de sire of the operator as will clearly appear from the following description.

The foregoing illustrations of punctuation or spacing are merely taken as examples and it should be understood that the invention is capable of various uses and for effecting spacing of widely diflerent varieties.

In the drawings, the frame of the machine comprises a base 1, corner posts 2 and a type ring or top late 3. Each type bar comprises a type ar proper 4, a guide link 5 and a driver 6, the driver being pivoted at 7 to the type bar and the type bar being pivoted at 8 to a guide link. Each driver is pivoted orra circu ar pivot wire 9 and is connected at 10 to an upright link 11 pivoted at 12 to an an ular fever 13 pivotally connected at 14 to a draw link 15, the forward end of which is pivoted at 16 to a device 17 pivoted on a fixed rod 18 supported in the base of the machine. The device 17 has a curved rearwardly extending arm 19 on which a key stem 20 is pivoted at 21. A guide link 22 is pivoted at one end to a fixed pivot 23 and at its opposite end to the key stem at 24. Each key stem is provided with a finger piece or button 25 by which the associate type action may be operated. The types normally rest against an inking pad 26 and a depression of a key 25 causes the associated type bar to be moved upwardly tothe printing point. In the upward movement of the type bar its associated guide link 5 contacts with a universal ring or frame 27 which is connectedto a depending stem or spindle 28. The lower end of the spindle is operatively connected to a forwardly extending arm 29 of a do rocker pivoted at 30 and carrying feed ogs 31 which cooperate with an escapement wheel 32. The escapement wheel 1S operatively connected to the carriage in the following manner.

Upon reference to Figs. 3 and 4 it will be seen that the teeth 33 of a clutch device 34 areadapted to engage corresponding clutch teeth on a member 35 which carries the escapement wheel 32. A spring 36 bears down on the clutch device 34 and normally maintains it in engagement with the clutch teeth on the member 35. The clutch device 34 is connected to a vertically dis osed hollow spindle or shaft 37 provided wit a flange or collar 38 and a pinion 39. The inion 39 meshes with a feed rack 40 secured y screws 41 to a guide bar or carriage truck. This guide bar is grooved on the front and rear sides thereof for cooperation with anti-friction balls 43 which are also received in fixed grooved guide rails 44. A platen frame 45 carries a cylindrical platen 46 which is journaled in the end bars of the platen frame. This platen frame is pivotally connected to the carriage truck or bar 42 and carries an anti-friction roller 47 which is supported on a fixed rail 48. The mechanisms thus far do 50 and is secured to the base of the machine by screws 51. This frame comprises side members 49 which sup ort 'a fixed s indle or pivot 52 on which upright actuating evers 53 are supported and adapted to turn. These levers carry denominational stops, separately indicated in Figs. 5 and 6 by the reference numerals 54 to 54 and which are or may be formed integral with their associate actuating levers 53. The levers 53 are slidable along the pivot rod 52 so that an adjustment of both the levers and denominational stops may be effected as will hereinafter more clearly appear. The lower end of each actuating lever 53 ispivotally connected at 55 to a push rod 56 that extends forwardly to the front of the machine where it passes through a bearing 0 ening in a supporting piece 57 secured to t e base of the machine. Each of the push rods 56 is provided with a finger piece or button 58 and an adjustable col a1 59 to which one end of a restoring spring 60 is connected, the opposite end of said spring being connected to a pin 61 carried by the supporting piece 57. Upwardly and rearwardly extending bracket arms 62 are secured to. the carriage truck or bar 42 and support a toothed column stop rod 63 which carries bifurcated column stops 64 which may be adjusted to any desire point along the column stop rod or bar to determine the columnar position of arrest of the carriage.

A universal bar 65, which constitutes a portion of the carriage releasing mechanism of the tabulating mechanism, extends in front of the up er arms of the upright levers 53 as shown in ig. 1. This bar is connected to depending arms 66 secured to a rock shaft 67 supported in bearings in the side members 49 of the tabulator frame 49. A forwardly extending arm 68 is also secured to the rock shaft 67 and is bifurcated at its forward end to embrace loosely the hollow shaft 37 and to cooperate with the collar 38 carried thereby. A rearward movement of one of the finger buttons 58 effects a forward movement of one of the denomination stops, thereby bringing it into the path of the column stop 64. This same movement causes the upper arm of the actuating lever 53 to move the bar 65 towards the frontof the machine, thus effectin an u ward movement of the hollow spind e or s aft 3.7 which results in disengaging the clutch members and freeing turning it forwardly out of the pathof the stops with the projected denominational stop.

49" of the tabulator frame.

spacing blocks has a cut-out portion 76. with from right to left under the influence of the usual spring drum (not shown) until it is arrested y the contact of one of the column From an inspection of Fig. 5 it will be observed that the side members 49 a of the frame 49 which receive the denominational stops 54 54 54, 54 54 54 54 54 54., 54 are situated a greater distance a art than the, combined width of the series'o ten denominational stops. The excess space in the present instance corresponds to the thickness of seven of the denominational stops, although this distance may be made greater or less. The manner of mounting the denominational stops and the actuating levers 53 of which they form parts is such that the levers and denominational stops may be moved or adjusted laterally or in the direction of the travel of the carriage when desired to different working positions, as hereinbefore pointed out. The spaces between the denominational stops, or at the outer side thereof, may be occupied by what I have termed spacing blocks. 69,seven of such blocks'being shown in the resent instance and each corresponding in t ickness to the thickness of a denominational stop, which corresponds to a letter space movement of the carriage. Each of t e spacing blocks 69 (see Fig. 2) is formed with a notched portion 70 by which the stop may be mounted and held in place on a rear cross bar 71 which unites the side members A detachable locking member 72 (see Figs. 2 and 5) extends across the top of the series of denominational stops and spacing blocks and is provided with downwardly bent ends which are received in o enings 73 in the u per ends of the side mem ers 49 of the tabu ator frame. By removing this locking member 72 or displacing one end thereof from its slot and s acing blocks they may be removed and shifted as desired. In the specific arrangement shown it may be assumed that the spacing blocks are arranged so as to separate the d nominational stops in order that pounds, sliillings and pence, for instance, may be written as thus:

.6 8. 03. 100,000.- -19 -10 or thus:

In order-that the lower ends of the actuatinglevers 53 may be spaced according to the spacing between the denominational stops, I have provided means which are best shown in Figs. 6, 7, 8 and 9. All levers 53, except the right-hand one" as viewed from the rear of the machine, are each provided at the rear side with a notch 74 by which a spacing block 75 may be applied to the rod. Each of these three teeth 77 on the opposite side walls of the cut-out, thus providing three sets of openings 78, 7 8 and 78 between the teeth, though a greater or less number of such teeth 1 and spaces may be provided. The width of each opening corresponds substantially to the thickness of one of the levers 53, and the width of the notch 74 in the lever corresponds substantially to the thickness of the spacing block 75. The distance between'two adjacent notches 78, 78" and 7 8 corresponds substantially to a letter spacemovement of the carriage so that each spacing block 75 may be adjusted on an actuating lever 53 and a contact edge 79 on the spacing block may bemoved one, two or three letter space distances nearer to or farther from the lever 53 on which the spacing block 75 is mounted. Each of the levers 53 is rovided' near'its lower end with an offset, ange or su port 80 on which. an associated s acing block 75 is ada ted to rest as shown in ig. 6. Each spacing b ock 75 may be readily disconnected from or connected to one of the levers 53 by bringing the cut-out 76 therein into register with the notch 74 in the lever to which the spacing block is to be a plied as indicated in Fig. 9. The spacing b ock may then be moved to the left in Fig. 9 so that one or more of the teeth 77 at one side of the cutout 76-will pass through the notch 74 until the set of openings 78, 7 8 or 7 8 with which the lever is to 006 erate are in register with the body of the ever. The spacing block may then be permitted to drop down to a position such as, shown in Fig. 6 where the spacing block will be supported on the laterally extending flange or support 80 and will engage the body .portion of the associated lever and the edge 79 on the spacing block at the left are contiguous, Whereas one spacing block 69 is inserted between thethird and fourth denominational stops 54 and 54 respectively. It requires therefore that a similar spacing be provided between the lower ends of the stop levers 53, hence a spacing block 75 is inserted in place in the manner hereinbefore described on the third actuating lever 53 from the left in Fig. 6, so that the innermost notches 7 8 in the spacing block will engage the lever, thus providing a single additional letter space between the lower ends of the third and fourth actuating levers from the left in Fig. 6. At this time the contact edge 79 of the spacing block 75 is maintained in contact with the side of the actuating lever which is the fourth from the left as seen in Fig. 6. This spacing of the lower ends of those levers 53 which are associated with denominational stops to each side of the left-hand spacing block 69 corresponds 1320 therefore to the s )acing between the denominational sto s of ected with the aid of the left-hand b ock 69.'- The three denominational stops 54 54 and 54 are contiguous stops 54 54* and 54 need no spacing at their lower ends other than that afforded by the projections 80. It is desirable,.however, that a distance correspondirfg to three letter space movements of thecarriage, or to the width of three of the spacing blocks 69, be

provided between the lower ends of the actuating levers of the denominational stops 54 and 5%; This is effected by adjusting one of the spacing blocks 75 so that the'spaces 78 therein co-act with the lever on which the spacing block is supported, thus affording a requisite amount 0 s ace between the actuating levers associate with the stops 54 and 54 In a like manner three spacing blocks 69 are provided between the denominational stops 54 and 54 and a like adjustment of one of the spacing blocks 75 is provided to properlyseparate the lower ends of the actuating levers for these denominational stops In order to maintain the lower ends of the actuating levers against lateral displacement in the positions to which they are adjusted, I provide a so-called compensating device designated as a whole by the reference numeral 81 and which is shown in detail in Fig. 8. This device comprises a spacing member or contact device, the body portion of which is bifurcated at 82 to straddle a supporting bar 83 which extends from one side member 49 of the tabulator supporting frame to the other and is secured at the front portionthereof in front of the levers 53. This supporting bar 83 is formed with serrations or teeth 84 for cooperation with the engaging end 85 of a spring-pressedloeking member 86 pivoted at 87 to the compensating device 81 and working in a slot in the lower portion thereof. This locking member on the compensating' device is adapted to engage with the teeth of the bar 83, whereas the body port-ion of the compensating device contacts with the left-hand actuating lever as viewed in Fig. 6 and maintains the levers against lateral movement in one direction when they are properly spaced apart, the projection 80 on the right-hand lever contacting with one of the side members 49. Thus, for instance, if the operator should desire to remove all of the s acing blocks 69 and 75 from between the (enominational stops and levers 53 respectively, in order to maintain all of the denominational stops contiguous one to another, then, all of the stops and levers should be moved to the extreme right as seen in Fig. 6 and the device 81 should be moved to the right in order to compensate for the space provided by the removal of the stops as to compensate for the space provided by the removal of the spacing blocks 69 from between the denominational stops.

While I have shown the construction arranged for seven spacing blocks 69 and have shown each of the spacing blocks arranged for an adjustment of from one to ithree spaces, it will be understood that the arrangement may be such that, a' greater or less number of blocks 69 may be employed and that the blocks may have a greater or less number of teeth 77 to give a greater or less variation in the adjustment of the blocks 75.

It is'believed that the operation of the mechanism will be understood from the foregoing descri tion.

Various 0 anges in the construction'may be made without de arting from my invention which, in its plates a provision of means for regulating the parts so as to vary at will the extent of spaclng between adjacent denominational positions of arrest of the carria e through the control of the tabulating mec anism.
