CARD PLATEN FOR TYPEWRITERS.
Application filed March 4, 1926. Serial No. 92,306.
This invention relates to improvements in card platen for typewriting machines, and the principal object of the invention is to provide means for holding a card in position with relation to the platen so that the type will strike the card just above its lower edge, or as close to said edge as may be desired.
The invention includes gauges for quickly setting in writing position cards of different lengths and widths. It also provides means for turning the platen with relation to the card holder whereby different portions of the surface of the platen may be used, to prevent 5' it from wearing unduly in any one place.
The invention also comprises a ribbon guard especially designed for use with the card holder, and adapted to act as a guide for the lower edge of a card, and other details contributing to the general purposes of the object of the invention.
The invention is illustrated in the accompanying drawings, in which:
i Fig. 1 is a front view of a typewriter platen with the card holder and ribbon guard in operative relation thereto;
Fig.2 is an end view of the same, looking tothe left from the line 2-2 of Fig. 1;
Fig. 3 is a central section on the line 3-3 of Fig. 1;
Fig. 4 is a section on the line 44 of Fig. 2;
Fig. 5 is a section on the line 55 of Fig. 1; F ig. 6 is a section on the line 66 of Fig. 5;
. Fig. 7 showsfront and edge views of one of the friction springs for holding theplaten yieldinglyfrom turning; I
Fig. 8 is a front view of the ribbon guard; and
Fig. 9 is an edge view of the same.
Referring to the drawings, 10 indicates the platen shaft which isremovably mounted in the carriage frame 11, as found, for instance, in the well-known L. G. Smith & Bros. typewriter. The platen embodied in the present invention. is interchangeable with the ordinary platen of the tpewriting machine.
The platen proper 12 instead of being fixed on the shaft, asis customary, is free to revolve on the shaft, but frictionall held in any desired position by means 0 suitable springs 13, located between the end plates 1 1 of the platen and head plates 15, 15*ofthe card holding frame.
The plates 15,- 15" are connected to hubs 16, 16 which are fixed on the shaft 10, being secured by suitable pins or screws. As shown in Fig. 2, the head plate 15 is provided with a notch 17 which is engaged by the usual holding pawl 18. The head plates 15, 15'' being rigidly secured 011 the platen shaft, are thus both prevented from turning and the card holder is thus held in fixed relation to other parts of the machine, with the exception of a slight adjustment in certain parts, which will be presently explained.
The head plates 15, 15 have upward projections 19 between which extend two rods 20 and 21, located above the platen. The rods 20, 21 are preferably rigidly connected together at their middle portions by a brace piece 20. Pivoted on the rod 20 are two card supporting arms 22. These arms, as shown, are oflight sheet metal having flanges 23 to stiffen them. The rod 21 passes through slots 24. in the lower ends of the flanges 23, which slots permit the arms 22 to rock slightly on the rod 20. Springs 25 coiled about the rod 20 and pressing against the arms 22 and the rod 21, as illustrated in Fig. 5, throw the upper ends of the arms 22 forward normally to hold the lower edge of a card against the platen, as will be explained hereinafter.
The arms 22 of the card holder are provided with slots 26 (Fig. 1) in which are mounted adjustable stops 27 which serve as gauges for the upper edges of the cards. The stops 27 may be adjustably secured in any desired positions on the arms 22. As shown in Fig. 5, they are frictionally held by means of spring washers 28. a V
Secured to each arm 22 is a finger 29 which is held yieldingly against the platen by the spring 25, before mentioned, and which is adapted to press the lower edge of a card against the platen. The fingers 29, as shown, are rigidly connected to sleeves 30 and the arms 22 are rigidly connected to the same sleeves, the sleeves being pivotally mounted on the rod 20. At their upper ends the fingers 29 are flared outwardly, as at 31, toform throats to receive the lower corners of the cards. The arms 22 and their connected fingers 29 are slidable endwise on the rods 20, 21 and they are held in any position to which they may be adjusted by the friction of the end of the spring 25 upon the rod 21, as
will be apparent from inspection of Figs. 5 and 6.
The cooperating ribbon guard is secured to a fixed bracket in the same manner in V "such "as-shown'atC in broken lines, Eig. 1,
which the ordinary ribbon guard is secured, and it is provided with the usual gauge 36 to indicate the bottom of the line 01' print.-
itis desiredto print on the lower-most margin of aeard, the card ismadeto register wlththls gauge llne 36.
The ribbon guard is provided with'twor upwardly projecting skeleton fingers '37 which are flared away tfrom' theplaten-at their upper ends 38. These flared'ends 38 serve to uide the card iii-toward thepla'ten and the fingers 37 hold the card close to the platen while printing on the lower margin thereof. i
The devices described operate in the at lowing manneri The fingers 29 are' L -shaped in cross-sectlonland-operate as side guldesfor the cards.
, The arms 22 =carryingthese fingers are adjusted upon the rods 20, 21 so that a card,
will be properly'centered with respect to the platen. The gauges 27 are-located with resp'ectto the particular size of card to be written-upon so that when the upper edge of the card is against the gauge, the lower edge-willbe'in position to receive a line of w-riting-onthe lower-most margin 01" the I position, the arms are tipped back-slightly against the tension of the springs 25 which -facilitates' slldlng the cards down under the fingers 29. This is also facilitated 'bythe outward flare of the upper ends of thevfin 'gers, shown at "31. Onreleasing "the arms the fingers 29 press the care to the platen,
.45 which is to'be-written-upon. Theoard-is thus just above the lower :margin of the card,
held close t rns platenwhile its lower margin is fully exposed so that a colnple'te line maybe written across the bottom of th-e'card.
The outward flare of the upper ends otthe fingers 37*oftheribbon guardalso facilitates 5 the placing of the card fin-"writing position. The frame carry ng the gauges is fixed "with relation to the typewriter carriage by the'holding pawl 18 and-the platen shaft is likewise-fixed. The platen, however, maybe -rotated upon its shaft to bring newsurfaces *to the printing point, thus preventing the, pla-tenfrom being worn unduly along a sin g'l'e 'line. The springs13 retain the platen platen described "may be quickly substituted for theusual platen of themachine. The
only other change required is to substitute the special-ribbon guard '35 for the usual ribbon guard. It will be understood that the the lower edges of the cards against the plateniam I Having described my invention, what I claim-is: Y
