TYPE-WRITING MACHINE.

Specification of Letters Patent.

Original applicatidnnfitd July 23, 1909, Serial No. 509,131. Divided and this application filed September 28, 1910. Serial No. 584,376.

To all whom ii may concern:

Be it known that I, Jenn Josnrn Coorna, a subject of the King of Great Britain, residing in the city of London, England, have invented certain new and useful Improvements in TypeJVriting Machines, of which the following is a specification.

This invention relates to typewriters and has for its object to provide an instrument by means of which a series of figures, letters or other signs may be successivcily impressed upon a narrow ribbon of paper or tape and especially for preparing drafts by textile designers for use in setting up the designs for weaving.

Letters Patent have been granted in Great Britain for this invention No. 19,474 of 1908.

Drafts have heretofore been prepared on what is known as point paper, comprising a series of ruled small squares, several of these small squares being inclosed in larger squares ruled in ink of a different color. The rows of small squares running horizontally of the paper indicate the pick or filling thread, and the rows of squares running up and down or vertically of the paper indicate the warp threads. The warp threads are carried by heddles or harness which are raised and lowered by means of mechanism operated a jacquard belt or I chain. The chain consists of links and bars,

and is at certain times wider than at others, according to the complication in the design of the weave. Each bar carries a series of risers, in the form of small wheels, and sinkers, in the form of filler sleeves between the wheels, said risers and sinkers engaging with an operating jacquard mechanism in the loom to raise or lower certain harness or heddles to permit a shuttle with the filling thread or woof to pass between such warp threads. Each horizontal row of small squares indicates such a bar of the chain with its risers and sinker-s; the risers or small wheels being usually indicated by a cross, and the squares left blank representing sinkers or filler sleeves. Assuming that the first three squares are left blank, a cross in" the next two, the next blank, a cross in the next three, and the next three left blank, this is read. and the chain constructed, as

follows: three down, two up, one down, three up and three down; meaning that the front three threads of the warp will be depressed, the next two raised, the next one depressed, the next three raised, and the next three depressed, and the filling thread passed. between such raised and lowered threads of the warp. It will readily be seen that in view of the large number of blank squares and crosses, mistakes can readily be made by the chain constructor, thus spoiling the entire design of the weave.

It is one of the objects of the present invention to provide an improved means of preparing drafts of a kind which can be easily read, without liability of errors.

In accordance with the present invention, a strip of paper is employed upon which numbers are typewritten to form a column extending lengthwise of the strip. Each number in the column consists of two figures.

1 The usual letter-spacing mechanism is preferably entirely omitted from the machine and two distinct sets of numeral keys are employed, one set for writing in the tens column and the other set for writing in the units column; each set of keys having itsown set of type bars; and the types being so placed that the numbers will appear in the desired order upon the strip. Line feeding of the strip is effected by a bar or key, which corresponds to the usual space key in ordinary typewriting machines. This line-feeding key is connected to a spool upon which the strip is wound after being written upon. Other features and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a front elevation partly in section. of an Underwood front strike writing machine modified in accordance with the present improvements. Fig. 2 is a plan view. thereof. Fig. 3 is a side elevation of the machine partly in section. Fig.4 is a sectional per spective view of the connection between the driving wheel and the winding spool.

At the left hand side of the keyboard of the machine is mounted upon levers 10a complete set of numeral keys 11 numbered from 1 to 9 inclusive, these being connected to a set of type bars shown diagrammatt .cally at 12 and intended to print only in sponding type bar [2 or 15. The type barsare all pivoted in an arc to strike through a common center guide 12, in the usual manner.

It will be seen that the type bars 1; are shorter than the type bars 15, that is, that the types 17 on the bars 12 are less remote. from the type bar fulcrum rod 18 than are the types ll) on the bars 15; while the type faces lie crosswise of the bars, or at right angles to their usual positions on ordinary typewriting machines. From this construction it results that any key 11 may he struck to print a number in the tens column on the horizontal paper strip JO and then 'that any key 14- may be struck to write a figure in the units column side by side with the figure previously struck in the tens column on said strip, thereby making a complete muuber.

The types in one set are mounted to strike above those in the other set, the types being set crosswise on the bars, to cause the impressions made by the types in one set to stand or read side by side with the impressions made by the types in the other set.

it will be understood that none of the keys 11 is capable of etlecting any feeding more meat of the paper, so that the strip lies motionless after the key it is struck and until the key 14- is struck, whereby the types opcrated by the two keys are caused to print side by side or caused to form a number reading transversely of the horizontal strip 20. in other words, the type 17 strikes upon the bottom edge of the strip 20, while the type it) strikes upon the top edge of said strip, but the types both extend longitudinally of the strip, so that when the. latter is removed from. the machine and turned to a vertical position the numbers read naturally from left to right forming a double column extending along; the strip.

The strip is fed in only one direction, that is longitudinally, and this is accomplished by means of a line feed key 21, which at each stroke ett'ccts a slight winding movement of a spool 22 to wind the strip upon the latter after it passes the platen 23. Before operating the line feed key 21, a special key 24- may be struck, this key connected to a typo bar 25 having thereon a divisor type 26 consisting of an underscore, which is of sufficient length to extend entirely across the strip thus dividing the latter up into sections, each section containing a complete number. This divisor mark has a function, which will be understoodiby those familiar with the weaving art, and the key 24 may be struck or not as occasion may require.

The paper strip 20 is paid off from a spool 21' at the rear of the machine; both spools being mounted on a horizontal forwardly extending shaft 28. The strip passes from the spool 27 around a fixed angle guide 29, whereby it is given a forward direction, it? then runs around a pulley 3t), and then across the machine in front of the platen and around a vertical pulley 31., thence back to an angle guide 32 over which it folds to wind upon the driving spool 22. The pulley should boyieldingly mounted to avoid liability of rupture of the weak paper strip or ribbon 20; and to this end the pulley may be mounted upon an arm 33 mounted to swing about a vertical axis 3t and yiehlingly pressed outward by a spring 33 against a stop 36; the spring being coiled about the axis 34.

The line-feeding key 21 eflects rotation of the spool shaft 28 by means of a-pair of arms 37 carrying said key and fixed upon a rock shaft 38, which extends horizontally across the machine; a returning spring 39 being coiled around said shaft. Backwardly from the shaft extends an arm 40, from the rear end of which rises a link 41, which is piroted atits upper end to an arm 42 loosely hung upon the spool shaft 98 and upon said arm is pivoted at 43 a driving pawl tat to engage a ratchet fixed upon" the spool shaft 28. intermittently and to drive both spools in the direction shown by the arrow at Fig.

Upon the shaft is also fixed a star wlreel 4C6 engaged by a detent roll 47 mounted. upon an arm 48 caused by a spring 49 to press the roll into the notches in said wheel 46, the

and carrying the un le guides 2-9 and 32.

At any time the spec 22 may bowound by means of a crank 55 fixed upon the vertical platen axle 56.

A yielding connection is provided be tween the driving wheel 45 and the Winding spool 22, to enable the key 21 to be depressed smartly Without encountering un- Said shaft is thus caused to turn,

' ing point; and these rollsmay be carried sent the number of warped threads to be due opposition to prevent sudden severe strain upon the paper strip. A collar 57 secured upon the spool shaft 28 is diametrically recessed at 58 to receive lugs 59 formed on a collar 60, which is loose upon the shaft 28; and a spring 61 coiled about the shaft yieldingly connects the collar 57 to the collar 60. The lug 59 is so small as to permit considerable relative play of said collars. \Vhen the space key 21 is struck sharply, the collar 57 turns in advance of the collar 60 and the spool 22; this'movement being permitted by .the spring 61; the latter serving to turn the collar 60 and spool 22 after the shaft 28 and collar 57 come to'rest. The collar 60, which is fixed to the wheel 22 and serves as its hub, may be frictionally connected to the shaft 28 to avoid undue accidental tension upon the paper strip. For this purpose, the spring 61 may be mounted to press the collar 60 against a collar 62 fixed upon the shaft. The delivery spool 27 is loose upon the shaft 28. The strip may be confined against the platen by soft rubber rolls 63, one at each 'side of the printupon yielding plates 64 secured by screws 65 upon standards 66.

The types strike through a ribbon 67 carried upon

spools

68, 69, which are operated in the manner usual in the Underwood typewriting machine; the ribbon being vibrated upwardly at each type stroke to cover the printing point in the usual manner. Thus it will be seen that the strip may be produced having thereon'the desired numbers, which will be read and understood by the operator, who sets up or prepa res the apparratus for weaving.

\Vhile, the figures occupy the relative positions of units and tens, it will be understood that they do not need to represent units and tens, but the Figures in the tens column for instance may represent the number of warped threads to be depressed, while the number in the units column may repreraised; and other uses may be found for the numbered strip. The divisor line may represent one pick or one bar in a chain; that is to say, the figures (of which there may be resent or indie-ate one pick or one bar in the chain. 5

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others. This is a division of my application No. 509,131, filed July 23, 1909.
