SPECIFICATION forming part of Letters Patent No. 776,017, dated November 29, 1904,,

Application filed June 18, 1904. Serial No. 213,171 (No model.)

To a, III/I/(J'IIII it *m/t concern:

Be it known that I, J noon FnLBnL. a citi zen of the United States, and a resident of the borough of Manhattan. city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in '.lype- Writing Machines, of which the following is a specification.

This invention relates to type-writing machines; and my main objects are to provide a base or support for the paper on which erasures or corrections may he made conveniently and also to utilize said base a mounting for the means for guiding and feeding the paper. i

To these and other ends, which will subse quently appear, the invention consists in certain features of construction and combinations of devices, all as will be hereinafter more fully described, and particularly pointed out in the concluding claims.

The invention is shown as embodied in the Monarch typewriting machine; but it is to be understood that it may be adapted to other forms of writing-machines.

In the accompanyingdrawings, Figure 1 is afragmentary top plan view of the platen and platen-frame of a type-writing machine .and showing my improvements embodied therein. Fig. 2 is a sectional side elevation taken on the line :1 a: of Fig. 1. Fig. 3 is a fragmentary front elevation of the right-hand end of the platen. Fig. 4: is a fragmentary perspective view of the right-hand marginal paper-linger. Fig. 5 is a fragmentary sectional side elevation of a modification of the invention. Fig. 6 is a front view of themarginal pa1:)erlinger and its bearing employed in connection with the modified construction shown in Fig. 5. Fig. '7' isa perspective view of the support of the marginal paper-finger shown in Figs. 5 and 6. Fig. 8 is a viewillustrating the method of mounting the erasingplate shown in Fig. 5.

In the drawings, 1 is thetop plate of the machine, and 2 one of the posts for the guiding and supporting rails 3 of the platen-carrier 4, the back bar 5 of which cooperates with therails 3 through roller-hearings and the side bars 6 of which furnish bearings for the platen 7. The paper-table 8 and paperapron 9 sustain and guide the paper 10 as it is introduced into and fed through the machine. The side bars of the platen -frame are provided with standards or lugs 11 and 12, which serve as bearings for an erasing table or shelf, which consists of a bar, plate, or blade 13, extending substantially the length of the platen, and of a rod or shaft-like portion 14:, the ends of which extend beyond the blade and are formed with holes which are tapped to receive shouldered screws 15. Fig. 1. Theshouldered portions 16 of the screws 15 pass through and bear in perforations in the lugs or standards 11. and 12, and the screws are screwed tightly into the ends of the shaft-like portion ii of the erasing plate or shelf, the shouldered portions 16 of the screws serving as pivots for and the heads of the screws preventing longitudinal motion of the erasing-shelf. The shaft-like portion 14 of the erasing plate or shelf has a groove 17 formed lengthwise on its under side, and the side or marginal paper-lingers 18 (the bearing portions 19 of which are cut away at 20, forming Gshaped hubs, in order that they may fit around or partially embrace the rear edge portion of the erasing plate or shelf) are formed or provided with tongues or lugs 21, which iit into the groove 17. The paper-fingers each comprise a thumbpiece 522, an arm 23,which extends forwardly over the erasing-plate, and a paper-guiding portion .24, which oilset from the arm 23 and conforms substantially to the surface of the platen. By means of the thumb-piece 22 the paper-fingers may he slid lengthwise of the platen to any desired position. The erasingplate may he graduated or marked to correspond in position with the graduations of the front platen-scale 26 to facilitate the positioning of the paper-fingers. although this is not essential. The tongue-and-groove connection between the paper-fingers and the erasingplate prevents any alteration of the relations between the parts other than an adjustment of the paper-fingers longitudinally of the erasing-plate.

Surrounding each end of the shaft-like portion 14 of the erasing-plate is a spiral spring 27. The outer end of each spring is held in the lugs or standards 11 and 12, and the inner ends of the said springs are confined in collars 28,which are fixed upon the shaft-like portion 14: by means of set-screws 29. The tension of the spiral springs 27 forces the erasing-plate about its pivots 16 toward theplaten, and this motion is participated in by'the paper-fingers 18,which are mounted on the erasing-plate or on its rod orshaft. This motion is limited by the contact of the paper-guiding portions 24 of said fingers with the surface of the platen or the paper thereon, and thus the paper-fingers are spring-pressed against the platen. The parts are so adjusted that when this contact occurs the forward edge of the blade-like portion of the erasing-table is in close proximity to the platen and the table as a whole is so disposed in relation to the platen that when the paper 10 is fed in and around with the latter it is guided by the paper-fingers up and over the erasing-table and its rod or shaft. The front edge of the table may at times act as a stripper that is, as a means for separating the leading edge of the paper from the platen and guide it upwardly and rearwardly and prevent it from following the platen. The rear portion of the erasing-shelf is supported above the top of the platen, and the shelf itself inclines downwardl y and forwardly in the general direction of-the delivery ends of the guiding-fingers 24:, as best seen in Figs. 2 and 5.

If at any time during the course of the writing it should be necessary to make an erasure or correction, the platen is turned in the usual manner until the desired place on the paper is brought over or upon the erasing-plate, which furnishes a firm and unyielding support for the paper while the erasure is being made and one which is exceedingly convenient for the operator.

In front-strike type-writing machines the rod or bar commonly employed for carrying the marginal paperfingers is usually so disposed in relation to the platen as to make it difiicult or quite inconvenient for the operator to make erasures or corrections on the platen. By my invention this ordinary form of bar is replaced by one which has a comparatively broad plate-like plane face, which serves the additional function of an erasingtable. It is arranged above and close to the platen and disposed at a convenient angle thereto, so that the paper as it is delivered from the marginal paper-fingers rests upon it. Little time or trouble is required for the operator to turn the platen so as to bring the desired place on the paper upon this erasingtable, and ample and unobstructed space is afforded thereon to make erasures. The erased particles of intermingled rubber, paper, ink, 620., instead of falling down upon the typebar bearings, as they ordinarily tend to do when erasures are made against the front face of the platen, remain upon that part of the paper which is above the erasing plate or table and will naturally be brushed back and away from the type-bars by the operator before the paper is returned to the writing position. The use of this combined erasing-table and paper-finger support thus tends also to prevent clogging of the type-bar pivots.

In the modified form of the invention (shown in Figs. 5, 6, 7, and 8) the ends of the erasingplate 30 are fixedly mounted in the platenframe 31, as best appears in the last-named figure. The paper-finger 32 is spring-mounted in a separate support 33, which is slidably mounted upon the erasing-plate 30, with which it has a tongue-and-groove connection similar to that hitherto described. The erasing-plate and the support 33 are thus seen to be relativel y fixed. The arm of the paper-finger device is pivotally mounted on the cross-bar 34:

and is pressed toward the platen by the spring 35. In the construction previously described. the erasing-plate and the paper-finger and its integral support are all pivotally mounted and spring-pressed.

It will be seen that the erasing-plate is so located and arranged that the paper need be moved but a short distance from the printingpoint in order to make an erasure; that the erasing-plate is in the best possible position for making erasures and also for making penoil-notes on and for ruling the paper; that the erasing-plate serves to support the means for guiding the paper around the platen and also transmits pressure to the said means, by which pressure the paper is held against the platen; that the erasing-plate is supported wholly at its rear portion above the platen and is arranged about tangentially of the upper side of the latter; that the paper is fed into the machine over the paper-table and behind the erasing-plate and is fed out of the machine over the erasing-plate; that the means for guiding and holding the paper are supported at the rear of the erasing-plate and project forwardly over the same; that the guiding and holding means aforesaid are movable longitudinally of the platen over the erasingplate, the latter being arranged between the platen and the supporting-arm of the paperfinger, and that the erasing-plate may also serve, when using tissue or otherlimp paper, which would tend to cling to and follow the platen, to separate or strip the paper from the platen after it passes the printing-point and cause it to pass over the erasing-plate, and.
