To all whom it may concern:

HENRY v 'rvrn-wmfrine magma):

I Specification of Letters Patent. Y Application filed October as, 1909. Serial No.

Be it known that I, HE'NRY Rnsou, a citizen of the United States, residing in Bayonne, in the county of Hudson and: State of New Jersey, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a speci fication.

This invention relates to means for guiding very stiff cards and the like around the cylindrical platens of typewriting machines, and particularly to those devices inwhich a rod extends over the platen from one end 'to the other of the platen frame, and carries a series of pendent fingers to hold the card against the platen, the pressure being produced by a spring; the rod with its fingers being detachably mounted on the ends of the platen frame, so that it maybe readily removed when not needed. A finger-piece is.

' usually provided'to turn the pressure fingers away from the platen for convenience in manipulating the card.

The principal objects of the invention are to improve the means for detachably mountand to secure an even distribution of pres-V ing said rod or bar upon the platen frame,

sure among a series of guiding fingers, and tosim lify the construction-and improve the operation of this class of devices. r

In the illustrated form of the invention, the upper ends of the card guiding fingers are fixed directlyupon a spring-pressed rock shaft, the latter having a key, whereby it may be turned to release the guide-fingers, and being mounted at its ends on the platen frame in a novel manner. The ends of the rock shaft are journaled in bearings carried upon the platen frame. The spring or springs for .saidgshaft are, of course, con-' nected between the shaft and the frame, sothat theplaten frame may a 0rd a support for the spr1ngs,.as they re-act upon the shaft, to cause the fingers to bear against the platen. I In .order to provide for the exigency ofv detaching the device from the platen frame,-

the springs are connected to the journal box or bearings of the shaft, and sa d ournal boxes are detachably mounted on the platen frame, so that in removing the fingers, the operator takes off also the shaft, the springs and the journal boxes, leavlng u on the platen frame nothing but the little" rackets inwhich theboxes are set The springs are platen,

laten which would give the-card atendenc bulge at the "printing line.

Theusual cylindrical "platen 1 of an Underwood ,front strike writin machine is journaled in -tlie platen frame .w ose ends are seen at 2. The types 3 strike against ;the.

front side of the platen.

For uiding very stifl' cards around'the l employ a series of fingers 4 pendent.

from a horizontal rock shaft-5 extending the platen. The card is indicated ill 11 6.1, 9 Fig. 1. The fingers may be' jointedtogethen by or'formed integral with a "late'TZ',!the.-, latter bein fixed-to the rock s aft.a5upon from end to end of the platen. fraine above its rear si c. It will bea'seengthat the ers descend about vertically, and then at 4, 1 curve forwardly and downwardly to; the, platen against which they. bear attpo nts di rectlyover the printing-line so .as ,to, head the card firmly back against the platen wh; .Q itis being rmted upon. From theirlower at n The ime 'is 1 its ends,-tlie-- ngers 4 extendzfupwardly away..,

ffrom the platen, so thatgtheygdo not ause,

'"on the shaft, which collar may berotatably Ql'a adjusted tof secure the desired pressure or .-te'nsion of the spring. The provision 'of twoadjustable, springs, one at, each end of l Shaft; is; a v age-, since any iequalityin'the pressure of the fingers 4: may

Ebefcorrected by either tightening r weaken- "ingone. of the springs; The other end of 'e'ach springis'connectedto a part which may betermed ajournal box, having'a bearing ortion; 10 in which the shaft turns, andalso .i-z failiaving aitongue portion 12, slipped into a ",notchofropen slot 13 in a bracket 11 secured upon .thejtop oftheplaten frame end-2. Relative rotation between the journal box and ;Shaft, whereby the spring may become weakened', is prevented by a pin'l-ffl projecting into'agroove'flT the shaft 5. As

' 1a matter of economy, the same'spring which presses the fingers against the plate'n also;

=. opera'tes to turn the journal box in a direc- "'35,t1on"to.cause'the tongue 12 thereof to take or snapunder ai -projection or catch '14 .formed, upon the bracket. at the .to of the 'slot' 13 so that-accidental remova of the cardguideisprevented.

The card is inserted and fed forwardly between the platen 1 and the; usual bottom 3. pressure rolls. 21, and up forwardly in; front of the platen. The operator then depresses a key'lS, which causes the shaft 5 to turn in its bearings, and the fingers 4 to swing for- "vvardly in front of the platen, shown in dotted lines at .Fig. 6. The operator then advances the card and-"releases the key 18, whereuponthe springs 8 cause the fingers 4 Soto-snap, down-upon the card-and hold it firmly against the platen close to the place where the eard' is to be written upon. The provision of two springs, one at each'end of d the shaft 15, is an advantage, not only be- .55 I justingthe spring pressure is well distributed.- among all the cause-of the practicability of relativelyadfingers, even though the shaft 5 may be of lightland weak construction. Moreover, by

.6 0,-.;having the'springs' at the ends ofsaid shaft, I

i they are" brought close .to their supports upon the latively unyielding-platen frame,

so that. liability of'bowing" ori springing the '.1" weaksh fta;ism gmz sa e e Peer a for-war s,- but also because the handles 15 provided upon the journal'boxes 10, and pulls saidhandlcs forwardly to turn said boxes around the stationary shaft in a direction OPPOSltG. to the tension of .the springs, to enable the tongues 12 to clear t e. catches 14. Then the operator may lift the handles 15 and Withdraw the tongues 12, as seen at Fig. 5, and lift the device away from the machine.

It will be understood that the groove 17 in the shaft 'is of sufiicient width to allow a little play of the locking in 15 to permit the required turning of tie box to disengage it from the catch 14. The pin 15.-

.may, ifj desired, be formed upon the inner g 'end of {the handle 15, as shown. In re plac1ng"the device noon the machine, the

finger pieces 15 are rst pulled forwardly,- to make it possible to insert the tongues 12 into the slots 13while the fingers 4 are rest- 35 ing against theplaten; and then the device is pressed down,- as at Fig. 5, until the tongues seat in the shops 13, and springs 8 snap the tongues under the catches 1.4.

Owing to the irregularities of manufacture, there is'someti'm'esa slight differencebetween the length of the platen frame in one machine, andthat of the platen frame inanot'her machine; and to compensate for such irregularities,either one or both of the journal boxes may be movable along the rockshaft 5; the groove 17 I being of sulfieient length to accommodate. such move-' ment. The springs 8 exert not only a turning'elfect upon the shaft 5, but also a pushing effect upon'the journal boxes 10, so that the latter are always brought snugly against. the brackets ,11, regardless of small variatiens in the distance between said brackets.

In securing the brackets 11 upon the machine, it is desirable to locate them in such a manner that the ends of the fingers 4 shall just clear the types ,3. To get this result, the brackets areslotted at 19 to receive their securin screws 20, the slots permitting and backward adjustment of the brackets. Adjustment of thejbrackets backwardly causes the fingers to drag around the platen away from the printing point. Forwardu-movement of the brackets causes the 5 fingers to move down upon the laten closer to the" printing point. There ore, the desired positioning of the fingers can readily be secured; and by movin the brackets forwardly and backwardly re ativ'ely toone an- 20 other, the fingers at one end of the row may be brought into the same relation with the platen as the fingers the-other endv of the row.
