TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Sept. 2, 1 913.

To all 207mm it may concern:

lie it known that I, Jonx Josnrn Coornn,

,a subject of the King of Great Britain, rc-

' by means of which a series of figures, letters or other signs may be successively impressed upon a narrow ribbon of paper or tape to form a telltale strip, and especially for preparinp drafts by textile designers for use in setting up the designs tor weaving, and more especially for the use of the wearer in controlling the grade, shade or color of the woof or filling thread. Letters Patent have been granted in Great Britain for this invention No. 19,474 of 1908.

inasmuch as a variety of designs is the sired in Weaving, a modified typewriter, which forms the subject matter of this invention, is used to typewritc the numbers in a column extending lengthwise of the telltale strip.

The usual letter-spacing mechanism is preferably entirely omitted from the macbine; 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 its own 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 etiected by a bar or key, which corresponds to the usual spare key in ordinary typewriting machines. This line-feeding key is connected to a spool up n which the. strip is wound after being written upon.

Other features and advantages will hereinatter appear.

in the accompanying drawings, Figure l s a front elevation partly in section of an Underwood trout 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. l is a sectional perspective of; the connection between the drivlug): wheel and the winding spool.

At the left hand side of the keyboard ot the machine is mounted upon levers a complete set of numeral keys ]1 numbered from 1 to 9 inclusive, these being connected to a set of type bars shown diagrammatically at 12 and intended to print only in the tens column on the strip. On the right hand side of the keyboard there is mounted upon levers 13 a complete set of numeral keys 14 numbered from 1 to 0 inclusive and connected to a complete set of type bars 15 at the right hand side of the machine intended to write only in the units column on the strip. As usual in the Underwood type writer, each lever 10 or 18 is connected to a sub-lever 16, the latter engaging the corresponding type bar 12 or 15. The type bars are 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 12 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 19 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 be struck to print a number in the tens column on the. horizontal paper strip 20, and then that any key 14 may be struck to write a figure in the units column side by side with the figm'e previously struck in the tens column on said strip, thereby making a complete number. The types in one set are mounted to strike above those in the other set, the types being set cross-Wise 0n 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 effecting any feeding movement of the paper, 'so that the strip lies motionless after the key 11 is struck and until the key 14 is struck, whereby the types operated 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 19 strikes upon the top edge of said strip, but the types both extend longitudi nally of the strip so that when the latter is removed from t e machine and turned to a vertical position the numbersread 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 effects 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 ma be struck, this key connected to a type liar 25 having thereon a divisor type 26 consisting of an underscore, which is of sufiicient 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 understood by 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 27 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 ulley 30, and then across the machine in ront of the platen 23 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 30 should be yieldingly mounted to avoid liabilit of rupture of the weak paper strip or rib on 20; and to this end the pulley may be mounted upon an arm 33 mounted to swing about a vertical axis 34 and yieldingly pressed outward by a spring 35 against a stop 36; the spring being coiled about the axis 34.

The line-feeding key 21 effects 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 pivoted at its upper end to an arm 42 loosely hung upon the spool shaft 28 and upon said arm is pivoted at 43 a driving pawl 11 to engage a ratchet 45 fixed upon the spool shaft 28. Said shaft is thus caused to turn intermittently and to drive both spools in the direction shown by the arrow at Fig. 1. Upon the shaft is also fixed a star wheel 46 engaged by a detent roll 47 mounted upon an arm 4-8 caused by a spring 49 to press the roll into the notches in said wheel 46, the teeth of which may be of any suitable shape. The platen 23 is cylindrical and mounted upon a vertical collar or shaft, the lower end of which carries a bevel gear 51 meshing with a pinion 52 on said paper spool shaft 28; whereby the platen :28 caused to rotate simultaneously with the advance of the paper strip. Th forward end of the shaft 28 is supported in a bracket 53; which also supports the platen and its appurtenances; the rear end of the shaft 28 being journaled in a bracket 54 fastened between the spools and carrying the angle guides 29 and 32. At any time the spool 22 may be wound by means of a crank 55 fixed upon the vertical platen axle 56. A yielding connection is provided between the driving wheel 45 and the winding spool 22, to enable the key 21 to be depressed smartly without encountering undue oppositionto 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. When 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 printing point; and these rolls may be carried upon 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. It will thus be seen that a telltale strip or indicator can be made which will have numbers thereon to indicate the particular grade, shade or color of the wool? threads at the different picks of the fabric. If the loom is of automatic shuttle type with but few changes, the stripcan be used by the designer or loom fixer to set the automatic shuttle control. If a large number of changes are necessary the strip can be arrangedto befed from the loom by a reel andratchet 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.

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