To all zo/tom ff' muy concern.'

Be it known that l, Jenn Josnrii (loornn,

a subject ot the King ot Great Britain, re-

siding in the city ot London, England, have invented certain new and useful Improvements in Type-VVriting li/iachines, ot which the following is a specification.

'llhis invention relates to typewriters, and has :tor its object. to provide an instrument by means ot which a series of figures, let-ters or other signs may he successively impressed upon narrow ribbon ot paper o-r tape, and especially tor preparing drafts by textile designers tor use in setting` up the designs tor weaving, and more especially tor the use of the weaver in controlling the 5 1a de. shade or color of the woot or filling thread.

The invention provides an improved means tor preparing` a woot color design dratt or telltale strip to be used in setting up the loom or more etten to go alonp; with the actual weavingl operation.

The woot dratt or tell-tale strip is in the form of a long strip ot paper having` a series of numbers arranged in a column extending` lengthwise of the strip, each number consistingr ot one or more digits.

rlt`he typewriter, which terms the subjectinatter ot this invention, is used to typewrite the numbers in a column extending lengthwise oit the tell-tale strip.

The usual letter-spacing mechanism is preferably entirely omitted from the machine; and two distinct sets ot' numeral keys are employed, one set tor writing in the tens column and the other settor writing in the units column; each set ot keys havingits own set ot type bars; and the types being' so placed that the numbers will appear in the desired order upon the strip.

Line feeding et the strip is effected by a bar or key, which corresponds to the usual space key in ordinary typewriting,` machines. rllhe space bar is connected to a pawl adapted to coact with a ratchet wheel on the platen so that when the space bar is struck a motion or partial rotation is imparted to the platen. rlhe platen is connected to drive spool upon which the strip is wound after beingl written upon. The platen is also connected to a counter or indicator which turns up a numli-er each time the space bar is actuated, givingn the number ot complete .numbers written, ii. a number is written 'For nach line, or in other words, giving the number of pick threads passed. at anypoint.

The usual movable carriage tor side spaciup,` is dispensed with and ribbon ot paper or tape tor receiving` impressions is ted in one direction only by means ot the space bar and indepeiulently oit the keys, impressions beine' eilected when the keys are struck.

@ne form of machine constructed in actor writingl a series of figures from l to 99, is provided with two sets of keys and typebars, one set lor the units and one set tor the tens and each set oit bars has a corresponding guide so that a units key and a tens key may be struck simnltaneously. The platen is oit the usual form but is capable ot rotation only so that when the keys .are struck no motion is impartedV thereto.

leterring tothe drawings, Figure l is aside elevation ot' one torni ot machine constructed in zucordance with this invention and adapted tor writing; a series ot figures from l to 99. Fig'. 2 is a 't'ront elevation. itin'. 3 is a plan thereof.

Duplicate keyboards comprising two sets oit keys a, I), and type bars ot the usual kind are provided, one set A 'for the units and one set ll 'lor the tens and each set of bars has a corresponding' guide c, d, respectively so that one of the keys a and one oit tho keys may be struck sinmltaneously. The keys are mounted as usual on levers ik', which are connected by sub-levers i? to the type bars in the manner usual in the Underwood trout strike typewriting machine; and all the type bars in both sets may be mounted on one it'ulcrum wire as in said Underwood machine; but they are constructed `so thatyene set strikes through one type `guide and the other set strikes through the y other type guide.

c is a platen of usual form, butis capable oi? rotation only so that when the keys are struck no letter feeding motion is imparted thereto. n. space bar f which is pivoted at f/ is adapted when depressed to rock the arm Il. and through a link m, to operate the lever j pivoted at 7i. Pivoted to the lever j is an arm n. carrying' a spring-pressed pawl o adapted to engage a ratchet wheel p so that y depression of the space bar f causes partial rotation ot the platen c, for line-feedingv the strip.

eordance with this invention and adapted` A spool Q mounted in bearings 1 on a frame s carries a supply of the ribbon t of paper or tape upon which the figures are to be printed. The ribbon 25 passes to the platen e through a guide u having a roller u and is adapted to be wound on a spool 'w mounted in bearings ai on the frame s. The spool fw is driven by a chain wheel y mounted on the spindle of the platen e and a chain ,e passing around said chain wheel g/ and around a second chain wheel 2 which is connected with the spindle w1 of the spool w by a collar 3 loose o-n the spindle w1 frictionally driven by said sprocket wheel 2, said collar 8 being resiliently connected by a coiled spring 3a to the collar 3b fastened on the spindle w1 so that the rotary motion of the sprocket wheel 2 is resiliently transmitted to the spindle w1. In order to prevent the spring 3aM from being overwound, dogs 3C on the collar 3b move in grooves in the collar 3 so that when said dogs engage the ends of their respective grooves the sprocket wheel Q will slip over the collar 3.

lt sometimes happensI that the same number should be repeated several times and it is not necessary to print such repetition but a corresponding length of ribbon may be fed through. This feed may be effected for a short series by depressing the space bar f the required number of times but to conveniently eifect such feed for a long series, a crank handle 4 is provided on the spindle of the platen e whereby said platen may be revolved to feed forward the ribbon. To enable the desired length of ribbon to be fed an indicating device or counter 5 is driven by a spur wheel 6 mounted on the spindle of the platen e and meshing with a pinion 7 on the device 5.

Each gure in type is arranged on its lever` according to its corresponding value, so that if a unit is to be struck the impressed figure will appear in the unit column and if a ten is to be struck the ten figure will appear in the tens column.

In the use of the device with the indicating counter at l7 and the strip in position, the number designating the shade, grade or color of the woof thread of t-he first pick is struck. If the number is less than ten, it is necessary to strike but one of the units keys; if greater than ten, a tens key as well as a units key must be struck. The keys of the two sets may be struck at the same time or successively. At any rate, the strip remains stationary while the number is being written at this particular point, corresponding to the particular pick of the fabric, whether this number contains one or two digits. The color in the rst pick may run for a number of picks. Of course the number of the color could be repeated successively at each point, but generally it would tnly be necessary to put the numbers at the points of change from one color to another. If the successive woof threads of the same color are few in number, the strip can be spaced up by the use of the space bar f; if, however, the number of picks of the same grade or color is great, the crank 4 is turned to bring the point on the strip corresponding to the first dierent pick up to the printing point. The counter 5 keeps track of the number of points or picks, so that the operator can tell at a glance the number of the pick without counting mentally.

It will thus be seen that a tell-tale strip or indicator can be made which will have numbers thereon to indicate the particular grade, shade or color of the woof threads at the different picks of the fabric. lf the loom is of automatic shuttle type with but few changes, the strip can be used by the designer or loom Xer to set the automatic shut-tle control. if a large number of changes are necessary the strip can be arranged to be fed from the loom by a reel and ratchet mechanism, so that points on the strip will show up at the same time that the corresponding picks of the fabric are being woven, calling the weavers attention to any changes in the grade, shade or color of the woof threads necessary. The weaver can then accurately shift the shuttle box to bring the proper shuttle into action at the proper time.

Having thus described my invention, I claim:
