TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Oct. ".7, 1919.

original application filed October 31, 1916, Serial No. 128,670. Divided and this application filed December To all whom it may concern:

Be it known that I, JOHN WALDI-IEIM, a

citizen of the United States, residing in Elizabetlu'in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to typewriting machines, and more'particularly to a tabulating mechanism; and is a division of my c0- pending application Serial No. 128,6?0, filed October 31, 1916.

A feature of the present invention is the provision of a key-set device to be used for selectively setting the machine for columnselecting work.

The stops for column-selecting are, according to the preferred manner of practising my invention, set individually in any one of a plurality of effective positions, transversely of the stop-bar, so that, with suitable mechanism to cooperate with the variously adjusted column stops, the car riage may be arrested at any selected columnar position or zone.

An additional feature of the invention is that the carriage may be arrested at any selected decimal point inany selected column or zone.

The key-set column-selecting stop device includes a column-selecting sto for each letter-space position of the carnage, and akey-controlled projector for selectively moving the column-selecting stops to eflective positions. Preferably, there is provided a plurality of keys in the key-board for moving the projector through difierent dis-' tances. e

Other features and advantages will hereinafter appear.

-The typewriting machine is of theregular Underwood construction, of which typebars 11 swing upwardly and rearwardly to print against a cylindrical platen 12, which rotates on an axle 13, in a carriage 14, which is driven from right to left of the machine by a spring drum 15, connected thereto by a strap 16. The letter-space movements .of'

the carriage are controlled by a suitable escapementmechanism having for this purpose a normally engaged rack 17, which meshes with a pinion 18, connected to the escapement wheel 19, the latter engaging with the reciprocating dogs 20, which are actuated during'printing operations by the type-bars 11 and a universal bar (not shown). I

To indicate the letter-space position of the carriage, there is provided a pointer 21, on the carriage 14, to cooperate with a scale 22, the latter being fixed on the frame 23 of the typewriting machine.

A decimal tabulator may be provided, as in my co-pending application herein referred to, which may comprise denominational stops 29 at the upper vend of plungers 28, which may be moved by suitable keys (not shown) into the path of a column stop 30 carried by a stop bar 31; the latter being secured to the typewriter carriage by brackets 32.

The carriage may be released during tabulating operations by the plungers 28 which engage with suitable mechanism, shown in my co-pending application herein mentioned, to lift the rack 17 against the tension of a spring 40 out of engagement 7 with theiescapement pinion 18. After the disengagement of the rack 17 from the pinion 18, the carriage is free to run from right to left of the machine, under the influence of the spring drum 15, until it is arrested by one of the column stops 30, en,

gaging with the actuated denominational stop or coiiperative stop 29.

The key-set mechanism comprises a key 50, and a second arm 51 located near the center of the machine. The upper end of the plunger-47 is provided with a finger 52,

' the relative position of which, with respect to the denominational stops, is as indicated in Fig. 4.

The column stops, of which there is one on the stop bar" for each letter-space position, are normally in their uppermost popointer 21 and scale 22, at any desired sitions. When it is desired to set any sele'cted column stop to an effective position, the carriage is located by means of the columnar position or zone, thus locating the selected column stop under the finger 52. The key 43 is then actuated, to move downwardly the stop-setting element or plunger 47, thus moving, by means of the finger 5 2,

the column stop 30 to an efi'ective position.

'To restore the stops 30 to their ineffective or neutral position on said bar, which is necessary before setting up a new combination of stops, there is provided on'the stop bar 31 a manually-controlled stop-restoring slide 53 (Figs. 1 and 4), which is moved leftwardly on the stop bar, against the tension of a spring 54, to cause an upward movement thereof, by means of shouldered.

screws 55 and cam slots 56. A stop-engaging portion 57 of the slide 53 underlies fingers 58 of the'stops 30; thus, when the slide moves upwardly, the set column stops are moved therewith until arrested by a second finger 58 formed near the lower edge of the stops- 30, and coiiperating with the under side of the stop bar 31.

To hold the stops 30 in any position to which they may be set, there is provided for each stop a spring-pressed ball 59, which drops into notches 60 formed on the stop'30.

I have provided several keys 43 to cotiperate with the lever 44, to move it selectively through. different angular distances, thus transmittin a variable movement to the finger 52 o the stop-setting element 47, to set any one of the stops 30, selectively, to any one of a plurality of positions transversely of the stop bar. The keys 43 are provided with key-stems 61, which are guided in suitable slots formed in a U- shaped plate 62, secured to the lefthand side of the machine frame 23 (Fig. 2), in

The stems 61 engage with bent-off fingers" 66, on the lever 44, to move the latter through different distances, there being a lost-motion between some of the stems and their cooperating. fingers for this purpose. In the drawings, I have shown four keys;

thus, any stop 30 can be setto any 011601 four positions, the position of the latter being dependent upon the key depressed. The 'four efiective positions of the-column stops 30 are indicated in Figs. 1, 2 and 4. Referring to Fig. 4, it'will be seen that the stops are set, from left to right, in the first, second, third "and fourth columnar positions. It will also be seen that the lower ends or engaging portions of these stops are arranged in stepped relation with respect to each other. It will further be seen, that by varying the normal positions of the 006perative or denominational stops 29, and with suitable mechanism used to move the denominational stops through the same distance, when actuated by their respective keys, any one of the denominational stops can be brought selectively into engagement with any one of the set column stops, as disclosed in my co-pending application herein mentioned. The plungers 28 are arranged so that they may be raised or lowered for this purpose by suitable column-selecting mechanism, (not shown), to bring the denominational stops 29' into effective relation with any one of the set column stops.

The column-stop-bar31 (Figs. 3 and 4) comprises two

parallel bars

101 and 102, between which are held the column stops 30, in suitable slots. The two parallel bars are separated from each other, and held in relative position, so that the slots in which the colunm stops move are in perfect alinement, by T-shaped members 103, one at each end of the stop-bar 31. The stop-bar is held assembled by screws 104, which pass through holes in the bar 101 and the members 103, and are threaded into the bar 102.

To give a brief description of the sequence of the operations of my invention, let it be,

assumed that all of ighe column stops 30. are in their uppermost r neutral position, on the stop-bar 31, in which position none of the stops are eifective.

Starting with the carriage at the extreme right, it is now'moved in a letter-space direction until the first columnar position is reached. The column1key of the key-set de- I vice is nowactuated, thus settinga column stop to the second uppermost position, by nieans of the finger 52, on the stop-setting element 47 ('Fig. 5). The key-set mechanism is now restored to its normal position by the spring 46, acting on the key lever 44, and oneof the springs 64, acting on the key-stem 61. This same operation is repeated, when the carriage is moved to the second, third and fourth cOlumnar positions, by depressing the column 2, column 3 and column 4: keys, respectively, (for the last position see Fig. 6). Thus the column stops are set, each with its engaging portion in a lower level than the previously set column stops.

The column stops have now been arranged on the stop-bar, as indicated in Fig. 4, and i the machine is ready for column-selecting.

For this purpose, let it be assumed that the denominational stops 29 are in their lowermost effective positions. If one of the tabulator keys is now actuated, the denominational stop 29 will be raised into the path of the column stop 30, in the fourth columnar position. The carriage is at the same' time released, to permit the column stop 30 to en gage with the denominational stop 29; the

latter will at this time be out of range of" the column stops, in the first, second and third columnar positions. The denominational position in the column at which the carriageis arrested is dependent upon the tabulator key actuated. If, after again returning the carriage to the right, it is now desired to position the carriage in the first columnar position, the denominational stops are moved to theiruppermost eiit'ective positions, so that when they are actuated by their keys, they will be brought into the path of the first set column stop on the stop bar. In a like manner the carriage may be positioned in the second and third columnar positions by first setting the denominational stops to their proper effective positionsby the column-selecting mechanism.

It should be understood that, although I have shown only four stop-setting keys, a greater number may be employed.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
