TYPE-WRITING- MACHINE.

Specification of Letters Patent.

Patented Apr. 9, 1918.

To all whom it may concern:

Be it known that I, CLIFTON B. CoRnLL, a citizen of the United States, residin in New York city, in the county of New ork and State of New York, have invented certain new and useful Improvements in Type- Writin Machines, of which he following is fication.

This invention relates to sheet collating devices for typewriting machines of the class in which sheet impaling pins or studs are provided to be projected through perforations in the side margins of work sheets arranged on a collating table, for alining the sheets or holding them in adjustable posi tion. The studs may be withdrawn from the work sheets after the latter have been adjusted, to permit the sheets to be advanced over he platen of the typewriting machine. As the impaling pins may be made to fit snugly in the openings in the sheets to ob-; tain a positive and exact alinement, it is important that the pins should be withdrawn by a straight line movement perpendicular to the sheets in order to prevent tearing of the sheets or displacement of the latter as the pins are withdrawn.

An object of the present invention, is to provide improved means for withdrawing the impalin pins in the manner stated. In practising tie invention the sheet collating table, which may be located at the delivery side of the platen to extend upwardly and rearwardly beyond the printing line, may be provided with a row or rows of impaling pins arranged to enter rows of openings provided along the side margins of the work sheets. In order to support the pins and permit them to be withdrawn in a direction normal to the work sheets, each row of pins may be carried on a shiftable support located behind the table, with the pins projecting through openings in the table, which openings may serve to position and guide the pins. Said supports may be actuated by cams to project or withdraw the pins. The cams may be in the form of inclined slots in actuating devices, mounted to slide on the rear face of the table, the slots arranged to receive studs on said supports so that the sliding movement of the actuating devices may serve to shift the supports toward and from the table to project and withdraw the impaling pins. The actuating devices may be operated by a key connected thereto through suitable mechanism, as for example, a rock shaft carrying the key, pinions on said shaft, and racks on the actuators driven by the pinions.

Other features pear hereinafter.

In the accompanying drawings,

he roller platen 10 is mounted on a platen axle 11, journaled in the ends 12 and 13 of the platen frame, which also comprises ,an inclined paper-shelf 14 at the intake side of the platen. Type-bars 153 (Fig. 4) may be operated by the usual mechanism to cause thetypes thereon to print at the front face of the platen. Front and rear feed rolls 16 and 17 bear against the under side of the platen and coiiperatc therewith to feed the work-sheets around the lower side of the Jlaten and upwardly past the printing line.

he feed-roll shafts are mounted on levers 1S, jourualed on a rod 19, said levers being actuated by a rock shaft 20 having cams or flats operative when said shaft is rocked to spread the arms 21 of said levers, and thereby throw the feed rolls oil the platen. A feed-roll release key 22 is connected through a link 23 to a rock arm 24: on the shaft 20, whereby, when said key is depressed, the shaft 20 is rocked and the rolls 18 and 17 are moved downwardly away from the platen. The feed rolls are restored to the platen by springs (not shown) when an upward pressure is applied to the key 22.

The platen may be rotated either by the hand-wheels 25 on the platen axle or by the usual line-spacing mechanism. The latter comprises a line-spacing lever 26 operable to move rearwardly a slide bar 27 carrying a pawl to drive a line-space ratchet wheel 28 connected with the platen.

The above described parts may be of the usual construction, common in commercial Underwood typewriting machines.

The sheet collating table 30, may comprise end sections 31 and 32 and an inter ,mediate connecting plate 33. The'end plates 31 and 32 are'ad ustably connected to the plate 33 by means of screws 34 extending throu h elongated slots 35 in said end plates and c mping the latter to the plate 33. By loosening the screws, the ends 31, 32 may be adjusted lengthwise of the plate 33 to ad just impalin pins or studs 36 for sheets 0).

different wi ths, or for adjusting the position of a sheet held by one row 0 pins relative to that of a sheet held by the other row of pins. The collating table 30 is mounted on the platen frame in position to extend upwardly and rearwardly from the platen so that work sheets a, b, on the laten may have their leadin ends overlie tl ie table 30,

permitting the s sets to be arran ed and alined on the impaling studs 36. cans for mountin said table, comprises brackets 37 on the p aten ends, a tie rod 38, connecting said brackets, and a rod 39 extending between the platen frame ends. Brackets 40, supported on the rods 38 and 39 have forwardly extendin arms 41 secured to the sheet collating ta le, as by means of clampin screws 42 extending through vertical slots 43 in the ends 31 and 32, and threaded into the bracket arms 41. This connection permits adjustment of the table toward and rom the platen, the screws 42 clamping the table in adjusted position on the said brackets 40.

The impaling studs 36 are arranged in rows adjacent the ends of the table 30, each row of studs being carried by a support 44 behind the table so that the studs extend throu h openings 45 in the table and project a ve the surface of the table and perpendicular thereto. The supports 44 are shiftable toward and from the table to project and withdrawthe studs, b means of actuators 46 having cam slots 4% to receive headed pins 48 extending through said cam slots and secured to the supports 44.

The actuators 46 are inounted 0n the rear face of the table for sliding movement thereon, toward and from the platen; such mounting'comprises headed ins 50 extending through longitudinal s ots 51 on the bottom or rear wall of the actuator into guide blocks 52 secured to and projecting rearwardly from the collating table near the upper end thereof. The lower ends of the actuators 46, are in like manner guided and supported b pins 54 extending through slots 55 in e actuator, said pins 54 being mounted on angle plates 56 attached by i turn the feed rolls l6 and 17 for holding screws or bolts 57 to an angle bar 58, secured to and extending lengthwise of the table along the bottom edge thereof. With this construction, the actuators 46 are ermitted to slide up and down on the table but are held against either lateral movement or movement toward and from the table.

Means for operating the actuators 46 comprises a key 66011 a rock shaft 61 to which are fixed pinions 62 runnin in mesh with racks 63 on actuators 46. he rock shaft 61'is mounted at the back of the 001- lating table, being journaled in bearing blocks 64, secured to the rear face of the plate 33.

When the key is thrown upward to the position shown in Figs. 1 and 3, the pincarrying supports 44 are held closely against the rear face of the table so that the ins 36 project through the openings 45 into gosition to permit the arrangement of the work sheets thereon. To withdraw said ins, the key 60 is swung downward to the ig; 4 position, thereby rotating the ElDIODS 62 and operating the racks 63 so t at the actuators 46 are slid upwardly or away.

from the laten. By this movement, the cams 47 sliding along the pins 48 move the latter rearwardly, that is to say, the carriers 44 are moved away from the table in a direction perpendicular thereto, thus withdrawin the pins 36 from the work sheet. It wi 1 be seen that the sup orts 44, owing to the pins 36 being held an guided in the openings 45 in the table, are only moved in a direction per endicular tothe table. The pins 36'are thus withdrawn without tearing or displacing the sheeets.

To permit the arrangement of the work sheets, the feed rolls 16 and 17 may be thrown off the laten by depressing the key 22. The first s est 6 may then be dropped on the paper shelf 14 and advanced around the under surface of the platen to bring the leading end of the sheet over the collating table 30. The sheet, by means of the perforations in its side margin may then be impaled on the projecting studs 36 whereby the sheet is alined and squared to the platen in osition to receive the first line of typewritmg. An outer sheet a with an intermediate carbon sheet may then be introduced between the first sheet and the paper shelf 14 and advanced to position to be written upon, the sheet bein adjustedlon the studs 36 and thus alined n the same manner as the first sheet. The sheets as thus arranged may have their leading ends at different positions of advancement depending on the character of the sheets and th t position at which the typewritten entries are to be made on the-several sheets. The sheets being thus arranged, the key 22 is lifted to rethe: sheets to the platen in their relativeposn :ion of adjustment. lhe key is now thrown down to withdraw the studs 36 so U: n the sheets may be advanced over the coliulillg tahhwithout interference from.

said pins as the platen is rotated.

'iulions may be resorted to within the scope of lhe invention, and portions of the improi'cnieuts may he used without others.
