TYPEwnrrine MACHINE.

Application filed December13, 1924. Serial No. 755,629.

This invention relates to. gaging and on for laterally positioning said car-d. Thereis provided a spring-leaf for holding the card against the table, and the ends of the spring are turned up on a bias, forming a throat for introducing the card between the spring and the table. I The card is then set.

up with its leading edge against gages, and the gages serve to pos tion the card for the line of typing. I

To assist in positioning and removing the card, the table supporting the card is provided with a concave linger groove which serves to expose a portion of the card at the rear of the leading edge'so that an operative may easily place a finger behind the card. for manipulating it.

In many cases it isdesirable to type a line near the'bottom edge of cards having an uneven leading edge, that is to say, a leading edge having a portion cut out forming a step Locating gages are provided having individual adjustments. For the purpose of supporting the gages there are provided upwardly-extending guiding pieces and gages sliding thereon. The slid ing gages may be set to different positions corresponding to the various outlines of the leading edges of the irregularcards.

Other features and advantages willhereinafter appear.

Figure 4 is a fragmentary front view of the gages positioned for a" card, having a portion of its leading edge out out.

Figure 5 is a perspective view, showing point. 23 near the "lower edge.

one of the paper-gages and a portion of one of the slide. o

card or work-sheet 10, upon which it is desired to type one line near its bottom edge, may be inserted, bottom edge first, in the front side of a platen 11, which is mounted on shaft 12 and is journaled in side frames 13. The work-sheet is first laterally positioned and truedby means of a turned-up edge lat-which forms an integral part of a table 15. The cardisforced downwardly between the -.ends 16' ,of a spring 17 and said table, and then pulled upwardly to a position as shown in Figure 1, in which the leading edge of the worksheet is bearing against regulating' or locating gages 18. Said gages are slidably mounted on guides lQyWhicharefastened to the table 15 by means of rivets 20 Having positioned the work-sheet, a .line of typing maybe printed thereon by strik guidesrupon which the gages mg type-bars 21 against'the platen. Then I the work-sheet may be removed, 1 a fresh sheet inserted, and a new line typed thereon. In order to assist in inserting and removing the work-sheet, there is provided a groove 22 inthe table 153 which extends.

downwardlyfrom its uppermostedg'eto a N Thi g o e is designe'd toexpose aportion of the rear of the leading edge 24, thus enabling the operative to grip the work-sheet conveniently with a finger. behind it. v j i i In many cases it is desired to type one line nearthe bottom edge of cardshaving an uneven leading edge,-that isto say, a leading edge having a portion cut' out, as shown in Figure 4, in which a: portion of it,

indicated by the numeral 25, is higherthan other portions, indicated by'the numerals 26 and 27, which indicate difierent steps to which the gages 18 may be adjustedto suit the outline of the cards. The-independent I adjustability of the two gagesof 'this device'enables the operative to use it. for cards having either a straight or stepped leading edge, and is a feature which considerably broadens the scope of work to which it may be adapted.

For the purpose to a typewritmg machine, and'in; order that the same maybereadilyt detached there from, there are'provided finger-screws 28 which are substitutedfor the screws normaler attaching this device lie surface. that its edge l lnay he placed perpendicu there are provided ly provided in the machine for holding a guard 29 on the frau'ies 13. Said screws 28 support a bar30 which is fastened between the screws 28 and a spacing washer 31. illhe har 30 is placed parallel to the platen 11 and has fastened thereon, by means of screws 32, the table Depressions 33 are formed in the table for concealing the heads of the screws 32, as shown in Figure 2, in order that the table may form a continuous flat For positioning the table '15 so larlv to the platen ll,

1 slots-3-i ce-operating with the which permit the adjusting of said table,

The g"ges 18 for positioning the work-- sheet COHIPXiSG a block into it rich grooves are'cut. =The guides 19 are designed to enter into the grooves 35, so that the blocl; may he slid along said guides, and the gages 18 are provided with screws Eldfor binding the block in any position to suit the outline of the leading edge of the work-sheet, or to suit the position of the line of typing and the size of the sheet.

The spring 17 isfastened to a supiorting memberor bracket 37 by means of a fastener 38, and the bracket 3'? is mounted on the table 15 of which it forms an integral part. As is shown in Figure 3, the bracket 37 is fastened to the table 15 by means of rivets 39, but it is obvious that the same might form a part of said table instead of being a separate bracket fastened thereon. The ends 16 of the spring 17 are bent outwardly and upwardly, so that the lowermost edge of the ends '16'is the only point bearing on the table. The bias at the ends of the spring 17 forms a funnel-like throat 40, as shown in Figure 2, for assisting in introducing the worksheet between the spring and the table. There are shown 1n the drawings means for introducing a work-sheet at the introductory side of" the platen including a paper-chute ll and pressure rolls 42 and 43.

The platen 11 is operable by means of a finger-wheel 44. These parts are shown to illustrate the relative position of the table which forms the subject of this invention.

The presence in the table 15 of the groove 22, whose wall may be. seated-in a notch in the bar 30, or be arranged with the same depth as the depressions 33 for engaging against the front edge of the bar, braces the thin one-piece plate or table 15 against be ing bent out of true by rough handling.
