iApplication filed November 7, 1910. fierial No. 591,025.

To all whom it may concern:

Be it known that I, CORNELIUS B. GonoonAiv, a citizen of the United States, residing in the borough of Bronx, city of New.

York, in the countyof New York and State of New York, 'have'invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification. I

This invention relates to paper-holding and guiding devices for platens of typewriting machines, and is more particularly designed to hold stifi' cards, labels, etc, in place to be printed'uponf Certain devices of this nature which have been permanently affixed to machineshave been found to project across and conceal 'a portion of the line of writing, and others, which have been made removable, were liable to be lost or mislaid when not in use. Y l The principal object of this invention is to provide a device which shall be affixed to applied to an Underwood front strike writing machine, the paper-holding fingers being in operative position." Fig. 2 is a seca guard roll 9 resting on a shift rail 9 formingtional View of the same, dotted lines showing the paper-fingers in idle position. Fig. 3 is a sectional plan; Fig. 4 'isa front view of the fingers in idle position.-

Types 1 strike through a ribbon 2 against a platen 3' fixed on an axle 4, mounted in the ends 4* of a laten frame.

verging fingers 5 of a type guide 6 mounted on a part 7 of the framework. The ribbon 2 is threaded through a vibratory carrier 8 havinglipsB sliding vertically on the type guide 6, said carrier being held in place by plate 9. The platen frame has a part ofthe usual platen-shifting frame 9 pivotedat 9, whereby the platen is- 'moved The types, are led to the printing point by the confrom lower to upper case position, or vice 'versa, to enable the upper or lower case Cards, envelops or labels l0 may be fed around beneath the platen 3 and 1 types to print.

up behind the ribbon 2. by the rear and front rolls 11 and 12.

Stiff sheets tend to bulge' away from the platen at the printing point, and toprevent this, a set of paper-holding fingers 13 is pro-. 'vided, said fingers collapsibly mounted on upstanding supports or guides 14: fixed to the machine. The fingers may be drawn up- Wardly across the printing line 15 by means 4 of finger pieces 16, so as to stand close to the platen at the printing line,to hold'the sheets against the platen. "Said fingers preferably present convex or bulging faces to the sheets,

to reduce or avoid the liability of displacing the latter relatively to the platen as the platen moves in letter-spacing direction, and

also to enable the side edges of the cards (when standing away from the platen and approaching the-fingers as the platen is fed step by ,step) to be forced backwardly by the fingers against the platen. The fingers are extensible preferably to a point above the highest or upper-case position of the printing line, to hold the sheets against the platen when printing upper case characters, and are prevented from being lifted out of their supports, by stops 18 against which portions of the fingers (as lips 17) strike. Pressure upon the upper ends of the fingers slides or collapses them over the guides 1. L, until said ends come to rest below the printing line 15, to leave the line of writing unobstructed. The finger pieces may, by encommodate themselves to sheets or sheaves of sheets of varying thicknesses.

Variations may be resorted to withln the scope of the invention.

Having thus described my invention, I-

claim: 1. In a front strike writing machine, the

I combination with a platen, of a paper holder supported in front of the platen normally below the printing line and extensible to a point above the printing line.

2. In a front strike writing machine, the

fingers movable up and down on said guides. '6. In' a front strike Writing machine, the combination with a platen, of guides, paper combination with a shiftable platen, of a paper holder supported in front of the platen normally below the printing line and I out of contact with the platen and extensible to a point above the printing line when-the platen is in either of its positions.

' 3. In a front strike writing machine, the

combination with a platen, of guides fixed to the machine, and paper holding fingers holding fingers collapsibly mounted on the guides, and stops to arrest the travel of the fingers on the guides, one of said stops on each finger serving as a finger hold to extend the finger on-the guide.

7 In a front strike writing machine, the

combination with a platen, of guides, paper holding fingers collapsibly mounted on the guides, and a finger piece on each finger to slide the latter .on the guides.

8. In a front strike writing machine, the combination with a shiftable platen, a ribbon carrier vibrated in front of the platen, and a guard plate for the carrier, of guides projecting upwardly from the guard plate to points justbelow the printing line, and paper-holding fingers slidable on the guides and extensible to points above the printing line when the tions.

9. In a front, strike writing machine, the combination with a shiftable platen, of upstanding guides in front of the platen, ,paper' holding fingers collapsible on the guides, and stops to arrest the fingers.

10. In a front strike writing machine, the combination of a platen which may be shifted for'upper and lower case types, a set of guides projecting upwardly in front of the platen is in either of its posiplaten and having paper .holding fingers collapsibly mounted thereon, and finger pieces to extend, the paper holding fingers to operative positions above the prlnting line.
