SPECFICATIQN forming part or Letters Patent No. 617,887, dated January 17', 1899.

Application iiled May 6, 1398i Serial No. 679,910. [No modeld I /"n (LN l/.nltont 1"/2 71mg/ concern/ Lic it known that I, HERBERT ll. STEELE, a citizen of the United States, and a resident ol New York, in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in 'iypeVriting lilachincs, of which the following is a specification. I

My invention has for its main object to provide a construction of platen and card-holder whereby the latter may be readily attachedto and detached from the platen and one in which when the cardholder is attached it is held or locked firmly in operative condition against casual detachment; and it is a further object of my invention to provide a construction such that the platen may also be used for writing upon paper in the usual manner when the card-holder is detached.

'llo these ends my invention consists, primarily, in combining with a platen having aperioration at or near each end a card-holder having spring-legs at or near its endsadapted to pass through said perforations and to engage at their free bent ends with interior parts f of the platen; and myinvention consists also in certain other features of construction and combinations of devices, all oi' `which will be hercina ter more fully described, and particu! larly pointed out in the appended claims.

In the accompanying drawings, Figure l is a vertical longitudinal section of a portion of a type-writing machine, showing my improvements. Fig. 2 is a plan view of the left-hand end of the platen. Fig. 3 is a central vertical section through the platen and its carriage or frame. Fig. 4 is an inverted perspective view ci' the card-holder. Fig. ois a vertical longi-l tudinal section of a modified form of my invention.

In the various views the same part will be found designated b y the same numeral of reference.

l designates the platen carriage or frame, u in the side or end barst)` of which is mounted to rotate the platen shaft or axle 3,Which may extend continuously throughout the center of the platen or which. may be made in sections, as shown. At each end of the plateu'is a knob or hand-wheel l JAor turning the shaft and platen. lhc pinion comprises, as usual, ahollow core 5, a surrounding cover or sheath G, and cylindrical ends or heads 7 and S, which are attached to the core by means of screws .l. The left-hand platen-head is provided with a sleeve or hub iO, which is attached to the shaft 3 by means of a set-screw ll. On the inner side of each platen-head is formed or provided a cylindrical iiauge l2, upon. which the core is seated, and the said llangcs are hollowed out or formed dishing in a manner to provide a tapering or beveled wall lnvhich extends circularly about the interior of the flange.

At or near each end of the platen, contiguous to the head, 'is formed a hole or opening 14, which extends through both the sheath and the core and communicates with the interior of the latter.

The cardholder comprises a bar or plate l5, slightly curved, as usual, to match the surface of the platen and formed at one edge With an undercut, so as to provide an overhanging lip or ilange lli for the insertion of the leading end ol' the card 17. Secured. near each end of the card-holder and on the under side thereof is a leg or projection 1S, which is preferably composed of springy sheet metal. The lower or free end of each leg or projection is formed with two oppositely-disposed bends 19 and 20, made, preferably, at

right angles to each other andat obtuse angies to the body of the leg.

The card-holder is attached to the platen by passing the legs i8 down through the holes in the platen until the bar or plate portion 1 5 of the card-holder bears upon the surface of the platen andthe bent ends ofl the legs engage with the flanges of the platen-heads, as shown at hig. l. During the passage of the legs through the holes in the platen the inwardly bent, or beveled extremities 20 first strike against the upper edges of the flanges l2 of the platen-heads and then slide along the same inwardly as the insertion of the legs is continued and until the said bends 20 pass beyond the holes in the core and into the interior of the platen. The beveled ends 2O act as cams or Wedges to bend or flex the elastic legs 18 during the time the beveled ends 2O are passing over the upper or outer edges of the flanges l2, ihus storing a slight IOO amount of tension inthe said legs, which operates to force the said legs outwardly again as soon as the beveled ends 2O have passed otT; of the sides of the flanges, and to thus canse the beveled portions lf) of the legs to press against the inner` edges of the flanges, as shown at l\`ig. I, and with a force great enough to secu rely lock orhold said legs, and hence the card-holder, against accidental detachment. 'lhe innersides of the holesflt in the platen are slightly beveled, as at 2l, to enable the legs to be flexed or bent by the bent orbevelcd portions 20.

dien it may be desired to remove the cardholder, thismay be readily accomplished by pulling up or upon the linger-piece or extension 2;, whereupon the beveled portions l!) will be forced inwardly by the edges of the flanges a sullicient e.\tent to enable the sharp bends at the junctions ot the parts l!) and 2O to pass by the flanges and out through the openings in the platen.` 'l'he portions It) of the legs engage slightly the tapering walls 13 of the dishiug portions of the flanges and have a hook-'like action thereagainst under spring-tension; but the hoolelike portionsl) are so formed relatively to the said flanges that they are adapted readily to automatically disengage themselves therefrom upon an upward or outward pull upon the cardholder, and the beveled vor bent portions 2O are so l'ormed relatively to the said flanges as to put' the tension into the legs and simultaneously guide t-he hook portions 19 into proper relationship with the flanges to lock or hold the card-holding eontrivanee upon the surface of the platen. In brief, the hook-like or b cnt legs spring or snap against and engage the flanges al'ter passing through the holes inthe platen and in such a way as that they may be readilydetaehed on the application ot' sut" licient force to the card-holderin a direct-ion to pull the legs out of' the holes.

lteierringnow to Fig. 5, the platen is shown as constructed similarly to that shown in the other views; but the bends in the legs of the card-holder are made in the reverse direction to those shown in t'h'c other views-that is to say, the bent or inclined portion l f) is directedv downwardly and inwardly instead 0i' downwardly and outwardly, as in Fig. l, while the portion 2f) is directed downwardly and outwardly instead o1" downwardly and inwardly, as in said other iigur'es, and by this variation in construction the portion l!) is adapted to cooperate with the inner edge ot' the core of the platen instead ol with the flange of the -platen-hcad, as previously described, but in substantially the same manner and with praetically the same results. 'lhe portion 20, however, coacts with the edge of the hole at the sheath in the inserting operation.

, I do not wish to be limited to the use of spring hooksor legs engaging or catching upon the flange l2 or upon the core of the platen, as it willbe apparent that other engaging portions or devices may be employed to coperate with said legs or hooks, and nnless otherwise specifically' stated I wish my claims to include any suitable device on or portion of the platen which may be used to cooperate with and engage said spring legs or hooks. I regard the said flanges, as well as the core, as portions of the platen, considered in its entirety.

lVhat I claim as new, and desire to secure by Letters Patent, is.

l. In a type-writing machine, the combina tion of a platen having holes and a card-holder having spring-legs provided with bends or hooks passing through the holes in the platen and engaging interior portions oi the platen.
