Application filed January 28,

T0 aZZ whom it may concern Be it known that we, .ALFREo G. F. Konowsni and HENRY N. MoKAY, both citizone of the United States, and both residipg in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improve ments in Type-Writing Machines, of which the following is a. specification.

This invention relates to devices for adjusting sheets of paper preparatory to writil'ig thereon in .typewriting machines Thepr esent invention is particulaflyintended for use in connection with sheets which are provided with marginal perfo a tions, as for instance at their ends, these perforations being provided'either for. the purpose of binding or .forother purposes; and we provide upon a work support or sheet-adjusting plate a. series of stuns, upon which the perforations in the sheet fit. The sheet is placed, or impaled upon the studs, and then the typewriting proceeds. The studs cooperate with the perforations to position the; sheet reference to the printing line .01; the platen Preferably the studs are movable, so that after positioning the work sheet, :they mey'disnppeer or sink'out oft-he holosin'the paper. 7

i l/ here {l the invention is used in. connection with the revolulole pla iefi 'of s. front'strike writing machine there ma y be employed a sheet-positioning plate or tablet extending alongthe platen, and said plate may lie over-the top of the platen, andth'e studs may project from the plate. In such ma-. chine, after the sheet is positioned by means of the studs, the usual pressure devices may be brought into use to holdthe sheet against the platen. Y

W here it is desired towrite several lines upon a Work sheet et one insertion in a. front strike machine, --t,he sheet may be released froiuthe studs. the studs may be connected to the same key that releases the usual pressurefrolls, so that when the pressure rolls are cast elf, the.

studsare. projected; and vice versa.

Where the p p with a plate extendiugelongthe revolub le plated, .it ossesses advantages over the and side's heet-gages heretofore used, Qinags f TYPE-WRITING MAGHZIIQE.

much as the studs hold the sheet. so thatit s not liahleto become displaced while the pressure rolls are still castott; but the invention is not limited to theseadvantages. Therc'may also be provided venting the studs from being accidentally withdrawn or pushed down'by the pressure of the operators fingers, thereon. For this purpose, a lock may be employed which automatically locks the studs in projected positions;.wh ile said key unlocks the studs or pins and causes them to drop to normal positions of disuse. The invention is not, however, limited to studs'whichslisappear; one of the principal foetuses of the invention being the provision of studsin such relation to the print ing line of plat-en, that whena work studs by means of l t :r tew i F or this purpose,

invention is used tin-connection sheet is impaled .on the .the sheet itself will lie in proper relation to said printing line or point. By means of the studs. therefore, the sheet may be positively and accurately adjusted. I

- Otlier featuresand advantages will hereinafter appear.

15 a perspective view of our invention shown as mounted on the platen frame of an Underwood typewriter looking from the rear of the machine. Fig. is a sectional end view in which all of the platen frame is omitted, excepting such parts as are more The shown in its operaclosely related to the improvement.

actuating mechanism is tive position to receive paper. Fig. 3 is a similar end View and shows the relative position of the parts when the positioning studs are in their normal. posit-ions. Fig. l is an enlarged detail view of one of the means for actuating the same.

typewriting machine carries a platen frame having the two" end pieces 1 and 2, connect- ,ed bya rod 4. The platen 5 is journaled lJE.-' tweenthe ends on shaft 6, having a fingerwheel 7:.

An inclined top paper adjustingtahle is arranged at the'delivery side of the platen, i in the,fom of, a,bridge-plate 8, surmounts withdraw or In the accompanying drawings, Figure l and adjust a sheet of the positioning studs and The carriage frame 3 of the Underwood means for pref lthe plaiteu end extends the length thereof,

being mounted on the plat-en frame ends 1, 2, and braced at 35 intermediate its ends. Bosses 9 and 10 project rearwardlyfrorn the body of plate 8 to form bearings for a pail of slieet'positioning or gaging studs 11 and 12, adapted to project up through the table 8, to receive the perforated sheets. These studs constitute in effect a gage. These studs are nmrmally below the table 8, but are projected by rocking a shaft 13, which is journaled in. bearings 14, 15 and 16' at the rear of the plate 8. The rock shaft (actuated by a key lever 26) is provided with downwardly-extend'ing arms 17, 18, slotted near their free ends to engage pins 19, 20, which project from the sheet-positioning studs 11 and 12 near their rearward ends, whereby said studs may be operated.

\ihen the rocker arms 17, 18 are moved forwardly, the pins 19, 20 are forced thereby forwardly along the longitudinal slots 9 and 10', which terminate in catch or detent openings 9, more clearly shown inl ig. 41. These catches retain the studs in their extreme forward positions, by engaging the pins 1.9, 20 which are forced to rock into them by reason of the contort-ion of the coiled springs '21. Each spring 21 has one of its ends attached tothe stud 11 or 12, and the opposite end anchored to a taper pin 22.

The positioning studs remain locked in their forward positions until the pressure rolls are restored against the. platen to hold the sheet inplace which extends around the platen. The cam'surfaces 23 in the returning slotted arms 17, 18 then release the pins 19, 20 from the catches, and allowthe distended springs 21 to return the studs totheir rearward positions, so they will not interfere with the advance of the sheet as the platen is revolved. i

As a convenient means for operating the rockshaft l3, we employ a crank arm 24,

- mounted'at one end thereof and connect the ducing the sheet 30 between the paper shelf 33 and the platen and in fitting the holes 31, 32 of the sheet on the positioning studs 11, 12; The return of the key lever to normal position restores the pressure rolls and swings the studcontrolhng arms 17, 18 to releasethe pins 19, 20 from the catches 9 after which the retracting springs 21 withdraw the positioning studs 11, 12 as the at:iii-controllingarms swing rearwardly.

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