TYPE-WRITING MACHINE.

Specification of Letters Patent.

Application filed June is, 1908. Serial No. 439,227.

and State of New York, have invented certain new and useful Improvements in Typeof which the following is a. specification. I v

This invention relates to the paper-controlling devices ,of typewriting machines, and especially to mechanisms for feeding webs of paper and severing the webs into slips or sheets as the writing progresses.

Heretofore it has been the practiceeither to remove the web from the ty'pewriting machine before cutting it into slips, or to tear the web'into slips during the progress of the writing.

The principal objects of my invention are to save the time and labor consumed in practicing either of said methods, and to avoid the production of rough edges caused by tearing the web into slips.

Further objects are to avoidthe'necessity of removing each slip fromthe machine as it is severed from the web; to provide for regulationof the length of the slipsto be cut from the web; and'to secure approximate uniformity in the length of the slips,

The operation of writing upon a paper web involves the return of the carriage at the completion of each line to begin a. new line, and also the advancement of the web in line-space direction; and I not only provide means for cutting the web transversely into slips, as distinguished from tearing, but I also connect. thecutting devices to the webcontrolling means, so thatthe operation of writing upon the web line by line automatically eflects the severing of the web into the involving no special operation on the part of the operator, and requiring no attention for this purpose; It is only necessary for the operator to perform the usual line-by-line writing operations; and the severing of the web takes care of itself.

The machine is adapted especially for making car records, as well as for other classes of work; records contain [each but .a single line of writing, I provide advancing mechanism which at one stroke feeds the web the length of a slip, that is, to position to begin the line on the next slip. This web-advancing mechanism is operated by a handle, and the latter is also used to return the carriage to begin the new line. One of the features of my invention consists in connecting the transverse web-severing mechanism to be operated by said handle, so that it is only necessary to operate said handle in the usual way for the usual purposes, in order to effect also the cutting of the web into slips. The transverse cutting of the'paper is preferably effected through said handle during the return stroke of the carriage, eflected by said handle, to begin the new line of writing; and with this in view I employ two cooperative cutting members, one connected to the carriage and one connected to the framework, so as toenable the movement of the carriage to shear the web from side to side. .Said cooperative cutting members are preferably ineffective during the usual move ments of the carriage to and fro in letterfeedin direction, especially since it is sometimes esired to return the carriage without cutting the web, as when more than one line is written upon each slip. I therefore cause said handle or lever to effect cooperation of the cutting devices by moving one to the other other words said handle first moves the cutting devices to cooperative position, and then draws the carriage back to cause said .devices to shear the web.

The line-feeding mechanism already referred to is auxiliary to the usual or main line-feeding mechanism, the latter adapted and since usually these.

a line-spacing or web" to feed the web line by line by means of-the usual carriage-returning lever; this being used whenever it is desired to write two or more lines on each slip. The auxiliary linefeeding or web-advancing mechanism is .made adjustable to regulate the throw of the platen. If all slips are to be the same size, the throw of the auxiliary lever will be redueed toc'ompensate for the extra space occiipied by the additional lines of writing on each slip.

In the preferred form of knife or cutter is connected to the machine frame, while a slitted bar is mounted upon the invention, a

the carriage to receive the edge-of the cut- Patented Dec. 14, 1909,"

m advance of the return of the carriage. In

' ter; the bar and paper being drawn past the knife, which during this operation shears the web.

Myinvention is illustrated as applied to the well v known Underwood front strike.

typewriting machine, having a cylindrical platen revoluble uponv the carriageg and for such a machine I mount the sl tted bar right.

over the front upper side of the platen, so

that the web may advance up from the print ing point to the front of said bar and in rear of the cutter. The latter, which may be in rotary form, is pivoted'upon a bracket,

and the bracket is spline d to a-rock shaft,

which is mounted upon the carriage, but thebracket is held against movement during the return ofthe carriage. The purpose of mounting the cutter upon the rock shaft is to enable the cutter to be swung into and out of engagement with the slitted bar, by

means of the lever orhandle which controls the auxiliary platen-rotating mechanism.

The operation of saidhandleis first to turn the cutter'into engagement with the slitted bar, and also to advance the web, and then .to return the carriage and thereby efiect the cutting of the web.

The cutting devices-are made adjustable toward and away from the printing point to vary the, position at which the first line of writing shall appear on the slip.

The transverse cutter may. operate in conjunction with a slitter that slits a single web longitudinally, as the same is advanced around the platen; so that the longitudinal and transverse cuts of the web are all efiected automatically. The illustration shows two'original webs wound on separate spools mounted cndvto end;.b ut these spools are readily replaceable upon the machine by a single long spool bearing a double width web, to be slit by the longitudinal slitter.

I may be removed.

Type bars 1 strike upon. the front side of a cylindrical platen 2,-revolubly mounted by meansof an aXle-3iirthe ends-5, ofa platen frame, which also comprises a rear paper shelf 4: inclining upwardly and rearwardly from the rear side of the platen. The platen is rotatable line by line by means of the usual. line-spacing mechanism, comprising a lever- 6 and a slidefitjoperated thereby; this line-spacing mechanism being all located atthe left; handend of the platen frame. Saidplaten frame is mounted upon a carriage. 7 running upon-rear and front tracks, the latter seen at 8. The types strike rearwardly through a ribbon 9 mounted upon a vibrator 10 and a type guide 11, is secured upon a bracket 12 fixed upon the framework 13. As, so far itemizedthe parts are incommon use upon said Underwood typewriting machine.

' paper web 14: is wound upon the'core 15 of a spool having flanges 16. The spool is usually carried upon a rear-wardextension of the main carriage 7. The Web is led up from the spool over: the topof .the paper shelf 4, and then down around the platen 2, and up in frontthereof to be imprinted by the types 1. Rolls 17, 18,'Fig. 11, press the web' against the platen, ,to -enable-the rotation of the latter. to advance the web. The

web may be slitted longitudinally by means of astationary knife 19., into two Webs 14* and 148; said knife being adjustable along the paper shelf 4, to determine the point at which the web shall be slit; said knife being formed upon a carrier plate 20 having a 1, and the

webs

14 and 14 may pass one each side of the longitudinal slitter 19, or the lattermay be adjusted to slit one of said webs, if desired the other passing through the machine without being slitted'; or by the use of an additional slitter provision may be made for slitting both webs simultaneously. It will be seen that the knife 19 may be formed by bending up a short flange on the lower end of the carrier plate 20, and sharp ening said flange to form a cutting edge.

The back edge of the knife is beveled as at 23, to form a point at 24 to puncturethe web when, starting the slit. The spool or spools may be adjusted along an axle 25 carried upon a carriage 26 connected to the main carriage 7, to travel therewith; Y Collars 28 provided with screws 29 may be used to se cure the spool or spools in different positions along said shaft, as required. Theweb, either-single or divided, is led up from the front side of the platen in front of a bar 30 having a slit 31 to receive theedge .32 of a rotary cutter 33, to sever the web transversely into slips, Fig. 5. Said slitted bar is mounted upon the platen frame, and extends along and over the platen. An apron 34 drops fromthe front side of said bar to cover i the gapbetween the same and the front face of the platen, to prevent liability of the web entering between the bar and the platen. A guide-rod 35 in front of said apron retains the web, said rod'havin'g bent up ends '36 to fasten it to the endsof the bar. The knife 33 is preferably revoluble, but it does not travel with the carriage when the latter is moving longitudinally or in letter-feeding direction; the web being severed by. reason of the relative movement between the slitted bar 30 and the cutter, in a direction longitudinal of said bar. The cutter is ivoted upon a screw 37 threaded into abrac et or head 38, which is loosely supported upon a rod or shaft 39, which is mounted upon the platen frame; movement of the bracket and its cutter in the direction of the travel of the carriage being prevented by a yoke 40 embracing the bracket 38 and secured by screws 41 upon the portion 12 of the framework; the base portion 42 of the yoke being divided to bestride the ribbon 9 and the type'guide 11. The shaft ,39 is rotatably mounted in bearings 43 provided upon a pair of brackets 44 secured upon the p aten frame, said roll 1 bracket 38 being splined to saidshaft by means of a feather 45 fitting in a cutter and its, racket may barotated from the normali-inefi'ective position at Fig. .4 to the working'position at Fig. 5, by means of said rockshaft 39, and held there, without interfer' I r I of the main. carriage 7, since the roll bracket oov'e'46 in 'said shaft. The

with the longitudinal movements or head 38 must turn with the shaft 39, while the latter is permitted to move longitudinally through the bracket, the latter being detained by the yoke 40 against traveling with the carriage.

The movement of the cutter 33 from the ineffective Fig. 4 position to the working position at Fig. 5 is effected by a handle 47 formed upon a lever 48, turning about a vertical shaft or axis 49 mounted in a supplementary platen frame end 50 provided at the right hand end of the platen frame.

'Itwill be seen that the lever has an arm 51, which engages tlie-tip 52 of a horn 53 fixed upon a slide 54, to thrust said slide rearwardly in its

bearings

55, 56 formed upon a bracket 57 secured upon the supplemental platen frame end 50. The lever arm 51 presses the horn and the 'slide 54 backwardly, and this movement is transmitted by means of a curved link 58. toa crank 59 provided upon the end. of said rock shaft 39.

turn said carriage to begin a new line, but

also to swing the cutter 33 into the slit 31 -in the bar 30, to sever a slip 60 from the Web, Fig. 5, said slip falling into a tray 61,

Hence it will be understood that a movewhich is secured at its front edge upon the v slitted bar, and extends back or r the top of the platen being provided with a ledge 62 extending around its rear and side edges; the slips accumulating in this tray and; being removed a quantity at a' time by the operator..

Adjustment of the slitted bar 30 up and I down or away from and toward the printing point is effected by the following means; Upon the ends of the bar are provided ears 62, whereby the bar is supported at onexend upon a bracket 63, and at the other end upon-f Y an car 64 formed upon the bracket 57;,

screws 65 holding the bar rigidly upon said brackets. Between the ears 6'2 and the (le vices 63, 64, are clamped the plates 44 .hav-

ing the bearings 43' for the cutter-control:

ling rock-shaft 39. partly by. the screws 65 and partly by screws 66. Said screws pass through vertical slots 67 in the plates 44., and arethreaded into holes 68 in the supports 63 and 64. It" will also be noted that the screws 65 pass through vertical slots (39 in the ears 62". Byloosen- Said plates are "held ing the

screws

65, 66, the plates 44', together with the slitted-bar' 30 and the cutter-con trolling shaft 39, may be adjusted down toward the printing ,line on the platen, or up thereform, and resecured by tightening the screws. Thus the line of writing may be caused to fall on the slip or web at any desired point from the top edge thereof. It will observed that the provision of the 58,:between the slide 54 and the crank time to time.

59 of the cutter-controlling rock-shaft 39, permits the bodily adjustment of said shaft up and down to the desired extent independently of said slide; and that the handle 47 may operate the cutterat all adjustments of In addition to the usual line by line platen spacing mechanism, part of which is seenat (3, 7, I prefer to employ an auxiliary platenturning or line-spacing mechanism for the purpose of advancing the web, after completing the writing of one slip far enough to begin the writing of the succeeding slip. If more than one line is written on each slip, the usual line-spacing mechanism is called into use to advance the web step by step between lines, the auxiliary web-advancing mechanism being thereupon used to advance the web between entries, or to position to begin the first line on the succeeding slip. In other words, the operator uses first one line-spacing mechanism and then the other, as the web advances; but if only a single line is written on each slip, only the auxiliary vweb-advancing mechanism will be employed. This auxiliary web-advancing mecha'nism preferably comprises the handle 47 and lever 48 connected to the web-severin'g mechanism as already described, so that one movement of the handle 47 may return the carriage to begin a new line, sever the web, and also advance the web to position for writing the next line thereon. The shaft 49 carrying said lever 48 is provided at its lower end with'a link 70, which is connected by a link 71 to a rack .72 mounted to slide horizontally .backwardly and forwardly in guides 73 fixed in the auxiliary platen frame end 50. The rack .72 overlies and meshes witlr'a pinion 74,- loose upon the platen axle 3 and fixed to a disk or member 75, upon which is pivgtedgat 76 a pawl 7 7 to drive a ratchet wheel 78, having .the same number of teeth as the usual line-space. wheel, (not shown) at the "left hand end of the platen.

A s ring v79 bearing on an arm 80 of the by a stop 81 provided upon a slide-bar S2 looped around the .wall of the auxiliary platen frame end 50 and secured by a screw 83; the latter passing through a slot in the outer arm 84 of the loop, to permit adjustinent'bf the stop 81 backwardly and forwardly, to regulate the throw of the handle 47 and the platen, and thereby to determine the length of the slips to be cut oil from the web. In the resent form of the invention it is intende that the handle 47 shall complete its stroke to the dotted line position, seen at Fig. 9, before thecarriage starts upon its return movement; and in order to avoid liability of the carriage making a false start, the vertical shaft 49 may be lengthened upwardly from the hub of the lever 48,as illustrated at Figs. 1 and 11, to make a hand-hold, upon the right hand side of which the operators forefinger may rest while his thumb turns the handle 47'; the pressure of the finger being sufficient to hold the carriage stead-y until the handle movement is completed. In order to permit, the

described regulation ofthe stroke of the auxiliary web-advancing mechanism, independently of the stroke of the cutter-controlling rock-shaft 39, and to gain other obvious advantages, the horn 53 is formed with a curved edge at its outer portion, the curve being concentric at Fig. 9 with the axis upon which the lever arm 51 turns. It will be understood that in moving from the Fig. 8 position to the full line positionin Fig. 9, the arm 51 drives back the slide 54, bymeans of the horn 53, thereby setting the cutter to the Fig. 5 position; while thereafter, during the movement of the arm 51 from the full line to thedotted line position at Fig. 9, theend of said arm rides idly along the curve 85 on the horn, maintaining the cutter in its working position, (Fig. 5) while completing the throw of the auxiliary Web-advancing mechanism. As soon as the dotted line position at Fig. 9 is reached, the operator releases the hand-hold 49, and by iii) means of the handle 47 pulls the carriage to .the carriage to position to begin the next line of writing. Upon releasing the handle 47, it may be returned to normal position by a compression spring 86 or otherwise, said spring bearing against the rear end of the rack 72. A draw-spring 87 connected to the horn 53 returns the slide 54 to normal position together with the shaft 39 and the cutter 33. \Vhen it is desired toturn' the platen ba :k\\-'ardly by means of a hand wheel 88, a lever 89 may be turned forwardly to cause an arm 90 thereon to bear against the arm St) of the pawl 77, to disengage said pawl from the ratchet wheel 78.

it will beunderstood that the auxiliary line-spacing mechanism has a substantially greater throw than the illustrated ordinary line-spacing mechanism, for advancing the web to a position to be severed.

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