I Application filed February 19,1907. Serial No. 368.282.

' To (I/Z] (Uh/07H it TIIICI/Z/ concern.-

Be it known that I, HARRY S. MoCoRMAoK,

platens and cooperating paper-feedin New York, in the county of NewYork and State of New York, have invented certain new and useful Improvements in Type-Writ ing Machines, of which the following is a specification.

This invention relates to therevolugle evices of type-writing machines. its ject is to facilitate the introduction of paper sheets between the platen and said feeding devices, which are usually in the form of rolls or yielding fingers pressing against the platen, and particularly to facilitate the placingof the leading edges of the sheet parallel with the line of writing that is,.to accurately gage the leading edge of the sheet and to'insure the maintenance of the'sheetin such gaged condition during its introduction between the platen and said pressure devices.

The invention. is especially useful when it is desired to insert many sheets in the machine together, as during. manifolding, since they may be readily placed with their edges even.

and parallel with the printing-line, and so maintained during their introduction between the pressure-rolls and the platen. After such introduction the sheets are maintained in proper relation by the cooperation of said rolls and platen, while the sheets are left free to take their usual coursein passing cutofthe machine.

In carry ng out my. invention-I provide a paper-clip, which extends along the platen and is normally open and inactive during the rotation of the platen, so as to permit continued revolutions of the platen independ-' ently of the clip. Said clip is preferably provided with a age, against which. the-leading edges of the s eet may be laced. Then the clip may be closed upont e sheets and held closed bythe pressure-rolls runnin thereon.

After passing said rolls and the ot er paperguiding devices usually employed the clip is opened automatically by means of a spring, which constantly tendsto hold the clip open. The clip is preferably carried around the platen by. the action of. the platen itself, means being provided to cause the clip to be operatively connected to the laten whenever the clip is closed. For tiis purpose I provide ratchet-wheels or the like uponv the ends of the platen and cause a pair of catches that are mounted upon the ends of the clip to engage said ratchet-wheels whenever the clip is closed to bcconie disengaged from said ratchet-wheels by the action of said spring in opening the clip.

Other features and advantages will hereinafter appear.

In the accompanying drawings, l igure 1 is a side sectional elevation of the platen-frame and platen of an Underwood front-strike type-writing machine provided with my im provements, the clip being shown in partlyopen position to receive and gage the leading ed es of thesheets. Fig. 2 shows the clip ful y opened and occupying its normal idle position back of and below the platen, where it is out of the way. Fi 3 is a perspective view of the platen and clip and the latter being shown in open position. Fig. 4 is a perspective fragmentary view of one end of he platen, illustrating certain details, the clip being shown open. Fig. 4% illustrates diagrammatically the preferred angle formed by the paper-gage with the surface of the platen. Fig. 5 illustrates the use of the clip in intro.- ducing sheets between the platen and the pressure-rolls. Fig. 6 is a diagrammatic sectional view showing the clip closed and illustrating the compactness of the clip and its main supporting-bar, whereby they are well adapted to effect an entrance between theplaten and the yielding pressure-rolls without necessitating the exercise of undue force in turning the platen. Fig. 7 is aperspective viewof the bar and its revoluble collars or hubs, on which the clip is mounted. Fig. 8 is a plan view of the clip and its supports, the clip being'shown closed. F i 9 is an inverted plan view of the clip. Flg. 10 shows the relation of the parts shown in Fig. 8 to the platen. Fig. 11 shows the clip in theposition which it assumes automatically after trated type-bars 1. strike rearwardly aga nst gage for the leading edges of the sheets, to

naled in the ends of a platen-frame, which.

a set of front rolls 7 press upwardly against Y Hinged upon the ends of the bar 1t) by the platen, the guide-plate 5 being formed with suitable transverse openings through which said rolls 6 and.7 play. The rolls 6 and 7 are usually mounted so that they may yield downwardly, all of the parts just described being in common use on said machine. y

Upon the ends of the platen are provided annular recesses or bearings 8 to receive loosely a pair of collars or ring-like journals 9, the latter rigidly connected byia bar 10, which extends along the platen and close thereto, which bar is beveled along its rear edge, as at 10*,- Fig. 6, to facilitate its introduction between the platen and the'yielding pressure-rolls 6 7. The bar has at itsends ears 11, which are fixed. to the collars 9 in any suitable manner, as by means of screws 12,

. and the entire device, which is seen at Fig. 7

removed from the platen,- remains stationary and idle during the rotation of the-platen, ex-

cept during the period when it is coupled to the platen by instrumentalities hereinafter described.

means of pintles 13 is a papenclip 14 in the form of a thin strip extending along the platen from end. to end thereof close to said bar 10. The clip is normally held in openposition, Figs. 2 and 3, by a spring 15. Along its rear edge the clip 'is-bent inwardly at right I I the front side of the paper-shelf 4, two of angles reform a ledge 16, which serves as a squarethem to-the platen or to bring them into parallelism with the printing-line, Fig. 1.

From the opposite edge of the paper-clip exclip resting against a stop in the form of a soft-rubber roll 18, carried upon the end of a spring-arm 19, secured by screws 20 upon these rolls 18 being provided, one at each end of the paper-shelt'4, and each carried upon a spring-arm.

When it is desired to introduce a card or sheet or a series of cards or sheets, the device may be turned to'the Fig. 1 position either by grasping the freely-rotatable collars 9, .which are knurled for this purpose, Fig. 3, or by taking hold of finger-pieces 21., formed at the ends of the clip, said finger-pieces being longer than the tongues 17. In either way I spring 15.

I upon the framework of said machine.

"position, where the clip is. held partly ope n by therolls in, against which the fingerpieces 21 are pressed by the action of the By this means the ledge 16 is brought to a position radial ol the platen to. gage the leading edges of the sheets. l Vhen the clip is brought to this partially-closed position, there are brought into action two catches 22, one at each end of the to engage the teeth 23 ot apair of ratchet-wheels provided upon the ends of the platen,

whereby the platen is temporarily locked to the clip and is enabled. to carr the clip device bodily around from the ig. 1 position to the Fig. 11 position, together with the sheets 25, and it will be observed that, as

hereinbefore stated, the construction of the clip is'such and the entire clip structure lies so close to the platen that the rolls 6 and 7 may ride easily thereover. p

The finger-pieces 21 may be of sufficient length to remain-in contact with the rolls 18 .until the rolls 6 engage and control the clip and keep it closed; but in the form of the invention illustratedthe said finger-pieces are only of sufficient length to remain in contact withrolls 18 and hold the clip partly closed until such time in the rotation of the platen as the clip enters the narrow space between the lower'part of the paper-shelf 4 and the platen, whereby the clip is 'revent-ed from opening. The sheets are all eld bythe clip in the original position to which they were adjusted upon the platen until the sheets are safely introduced between the paper-guiding devices and the platen, (see Fig. 11,) so that the original alinement or squaring of the sheets upon the platen remain undisturbed. The tongues 17 are engaged by the rolls 6 7 and also by the usual front paper or card guide 26 (see dotted lines, Figs. 10 and. 11) in the form of a wire loop customarily provided After passing said loop'the clip is opened wide by a spring 15, Fig. 1 1, disengaging the catches 22 from the ratchet-wheels 24 and bringing the clip to its idle position and permitting the I said clip to ride backuntil arrested by the top of the platen, as seen at Fig. 2, the open i rolls 18, Fig.2, the alined sheets 25 passingthrough the machine in the usual manner.

The ratchet-wheels 24 are "in the form of flanges formed upon hubs or rings 27, slipped over the heads 28 of the platen, and secured by screws 29, Fig. 1. The clip carrying collars 9 are confined between said ratchetplatenand the usual or any suitable-pres, sure devices, which. instrumentalitiesj will' machine.

thereafter hold the sheets to the platen in the usual manner, while the leading edges of the sheets are left freerwithout anything-to interfere with their usual progress out of'the 'Variations may be resorted to within the scopeof. the invention, and portions of my improvements may be used Without others. "he gage 16 is preferably given a slight lead or advance inclination outwardly from the: platen, Fig. 4, so that the'outermost" sheets of an inserted pack have originally positions in advance of the inner sheets neartra distance traveledby the outer sheets in going around with the platen, so that when the sheets have reached writing-positions their leading edges standeven'lor flush with] one. another.

The platen is'in the ,forinlof a cylinder having an uninterrupted printing-surface,'-and the clip iscaused by the rolled? and other papenguiding devices to press. the paperdirectly upon or against said printingfsurfacej Having thus described'iny invention, I
