TYPE-WRITING MACHINE.

Specification of Letters .Patent.

Application filed October 20, 1915. Serial No. 56,857.

, To all whom it may concern:

Be it known that I, Jesse A. B. SMITH, a citizen of the United States, residing in Brooklyn borough, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to devices for controlling the paper in round platen typewriting machines, and particularly to machines of the class in which sheets are conducted around the platen by means of a chute; the

sheets being dropped, one by one, in rear of the platen, and each pushed aroundthe platen to bring the first line thereon to printing position; the chute having not only a floor, but also opposite side gages which extend around under the platen and up in front thereof.

One of the objects of this invention is to make it practicable to write a tally-strip record of entries made upon the sheets that are introduced successively in the machine by means of the chute. In carrying out the invention, the sheet is made of extra wldth, to afford room for writing the amount that is to appear upon the tally-strip, and a special tally-strip platen in preferably arranged at the right-hand end of the usual cylindrical platen, but within'the confines of the chute, which is preferably so wide that the main portion thereof is left unoccupied by the tall strip, so that the main portion of the wor -piece may be devoted to entries that are not to appear on the tally-strip. The contour of the extension of the chute agrees with that of the portion of the chute which passes under the platen, so that the widened sheet may be readily introduced between the side gages of the chute, the main portion of the sheet passing under the'main platen, and the right-hand margin of the sheet at the same time following around the floor of the widened portion of the chute; the tally-strip being between the sheet and the platen, so that the original or' ribbon impressions are made on the sheet. Tally-strip spools are arranged between the ends of the chute, so that a strip may pass from one around the tally-strip platen afid thence to the other spool. after the tally-strip is adjusted, the main sheets may be introduced .successively and Written upon, with tally entries appearing Thus it will be seen thatv upon both the main sheet and the tally-strip. The depression of the key which releases the feed-rolls from the main sheet is relied upon to effect the line-spacing of the tally-strip.

The invention may be carried out in a number of ways, and it is not necesasry in all cases to have the tally-strip platen sta tionary as is illustrated herein. Preferably the chute is bodily adjustable to some extent relatively to the main platen and the tally-strip; and the chute may also be formed in telescopically adjustable sections.

The side gages or guides for the main sheets may be adjusted to accommodate different widths, and the relative position of the main sheet widthwise with respect to the tally sheet, may be changed as may be desired.

The chute has side gages which extend under and around the platens to the front thereof, and between which the sheets overlapping both platens are set. The chute is sectional so that either or both gages may be adjusted for worlgpieces of different sizes, or so that theilative position of the workpiece and tally sheet may be changed at will. The relative position of the gages and the tally sheet may also be changed by adjustment of the tally-sheet mechanism on the platen carriage.

' Other features and advantages will hereinafter appear.

In the accompanying drawings,

Fig. 4 is a View in perspective of the chute, looking from the right-hand rear corner.

The platen carriage is shown as of a construction commonly found in Underwood typewriting' machines. Its letter-feed and return movements may be governed by the mechanisms common to such machines. The

platen 5, is mounted on'an axle 6, journaled in side plates 7 of the carriage; only the right-hand side plate being'shown. These 1 the work-pieces to be slid into position for receiving the first line of writing. They are thrown off the platen by means of a key 16, on a rock-shaft 17, to which is also fast an arm 18 having a pin-and-slot connection 19 and 20, with a link 21, connecting with a crank 22 on a rock-shaft 23. The roll shaft 14 is carried by bell cranks 24, and springs 26, attached to the rod 10, bear against the upper arms of the bell cranks, to hold the rolls normally against the platen, wit 1 the lower arms of the bell cranks against flats or cams 28 on the rock shaft 23, so that when the latter shaft is turned by movement of the key 16, the rolls are thrown from the platen.

The tally-sheet mechanism may be of the character shown in the patent to McCormack, No. 921,619, dated May 11, 1909, to which patent reference may be had for a detailed description thereof. Briefly, said mechanism comprises a segmental platen 30 carried by a pair of plates 31, supported in part by the platen shaft 6, but which are loose on the platen shaft, so that, while the platen revolves or has line space movement, the platen has no such movement. The platen 30 is located alongside the platen 5, beyond the right-hand end of the latter; and the printing face of the platen 30 is curved and in general alinement with the printing face of platen 5, so that the printing surface of the laten 30 forms an extension of the printing surface of the platen 5. The carriage rod 9 and the platen axle 6 both pass through a pair of plates 32 and support the latter; and a bolt 33 connects the plates 31, which carry the segmental platen, to the plates 32, thus preventing free angular movement of the segmental. platen. Slots 34, in the plates 31, provide for angular adjustment of the segmental platen when the bolt 33 is loose. I

The tally sheet 35 is led down from a supply roll 36, behind a roll 37, under an idler 38, secured to the plates 31, thence up and across the face of the segmental platen, over an idler 39, also carried by the plates 31, and thence to the take-up roll 37 to which the leading end of the tally sheet is secured. The roll 37 is turned step by step to feed the tally-strip; and this feeding operation takes place when the key 16 is actuated to release the work-piece from the feed rolls 12. For this purpose, there is fast to the tally-sheet feed roll 37 a'ratcht wheel 40, adapted to be engaged and rotated by a dog 41, on the link 21. The slot 20 in the latter permits the dog 41 to be swung 6 in and out of engagement with the ratchet wheel. The dog is normally in engagement with the ratchet wheel, so that when. the link 21 is lifted by depression of the key 16, the ratchet wheel is moved by the dog until a shoulder 42 on the link, by striking, the axle 6, throws the dog forward out of engagement with. the wheel.. On downward movement of the link 21, when the key 16 is released, another shoulder 43 on the link finally strikes the axle 6 to throw the dog into the ratchet wheel, where it remains to hold the wheel against rotation, until the key 16 is again operated. The transfer from the work-piece to the tally sheet is made by means of a carbon sheet 44 led from a roll 45 and thence following the path of the tally-strip. Therolls 36 and 45 are journaled in standards 46 supportedby the rod 9 and plates 32.

As the tally sheet is to provide for tabulation of the accounts or items appearing in statements successively written in the machine, it is important, as heretofore stated, that figures of the same denomination, as transferred by the carbon sheet from the individual statements to the tally sheet, appear in the same column position on the tally sheet; and, since the items to be transferred to the tally sheet are written in a definite position on the individual statements, it therefore follows that the placement of the statement sheets over the tally sheet, preliminary to writing, should in all instances be the same. For this purpose there is in the present instance, a chute on which the bills or other work-pieces are supported and guided to printing position on the platens. The chute has gages for the side edges of the bills so that there can be no deviation in the column positions on the several bills with respect to those on the tally sheet.

The chute shown in the drawings comprises sections 50 and 51, relatively adjustable lengthwise ofthe platens to vary the width of the chute to accommodate work- 7 pieces of difierent widths. Each of the sections may comprise a flat body 52 extending upward and rearward from the platen, and a curved portion 53 extending forward beneath the platens and upward to within a short distance of the printing line.' The curved extensions conform to the curvature of the platen 5, and are spaced from the platens to provide a passageway 54 through which the work-piece may slide freely, to bring it to position to be written upon, independently of rotation of the platen 5. The straight portions 52 form an introductory guiding shelf or floor. The sections 50 and 51 are provided at their outer edges with side gages or guides 55 and 56 for the edges of the. work-piece. These gages may be in the form of upward projecting flanges which comprise extensions 57 and 58 curved around the platens,

whereby the work-pieces are guided to the v printing line until the last line has been the platen. In the construction shown, the

flange 55 extends completely around the platen 5, the platen 5 in reality lying within an opening in the flange 55.

The chute sections 50 and 51 may have telescopic connection for relative adjustment, the section 51 carrying at the upper edge thereof a headed set-screw 59, which passes through a slot 60 inthe section 50, the section 51 also carrying a similar screw 61 which passes through a slot 62 in a bracket 63 on the outer lower face of the section 50. The slots 60 and 62 extend lengthwise of the platen, so that when the screws are loosened, the chute sections may be slid over each other to form a chute of desired width.

The device in the form shown, is designed for use as an attachment to the Underwood machine, and when so used, may overlie the usual paper shelf 11 and have each of its sections 50 and 51 connected to the rod 8 behind the shelf 11. The means for so connecting the chute to the rod 8 may comprise brackets 64 slidable along the rod and held against free rotation thereon by rolls 65, held by leaf springs in a groove 66 in the rod. The curled or bent-over extensions 67 of the chute sections are pivotally connected at 68 to the bracket 64. The chute sections are cut away at 69 to provide access for the feed rolls 12 to platen or work-piece thereon.

It will be noted, (see Fig. 2), that the segmental platen 30, and the tally-sheet spools, lie between the side gages of the chute. For convenience in assembling, and to provide access to the tally sheet, and to other parts below the work-piece, the righthand gage or flange 56 has its outer edge cut away at 70 and 71. This gage does not embrace the platen 5 as does the gage 55, because the platen 5 is discontinued to the left of gage 56 to allow space for the segmental platen. The rod 9 which carries the tally-sheet feed spool 37 passes over the gage 56, but passes through the gage 55 and serves as a support for the chute section 50. The chute section 51 on the other hand, has an independent support on the platen axle in the form of a bracket arm 72 fast thereto, and perforated at 73 to receive the platen axle 6, which latter, however, turns independently of the arm 72. The bracket 32, to which are secured the segmental platen and the spool standards, may be set at desired position on the rod 9 and platen axle; and, unless reset, remains with the tally sheet at a definite position in the chute.

im rovements may be used without others.

The gages 55 and 56, in determining the position on the platens, of the bills or other work-pieces inserted into the chute, also determine and render constant, the position of such Work-pieces with respect to the tally sheet; that is to say, for any given setting of the chute and the tally-sheet device. The bill form is so inserted, that the right-hand side thereof, passes down the chute between the latter and the tally sheet, or rather between the chute and the carbon sheet 44, and consequently, at the printing line the bill form overlies both of the platens, with the tally sheet directly against the segmental platen, and with the carbon sheet behind the bill form, between the latter and the. tally sheet.
