I have shown my invention embodied-.in the present instance vin .a Ironteed Remington 'type- Writing machine v.in which .the devices of .my present 'invention .may readily 'be incorporated without materially modifying the existing structural r features `of saidmachine, .as will hereinafter appear.

The .carriage .of the .machine comprises a truck (Gl. 19T-127) .having end bars 1,.a front cross bar 2 and a rear cross '.bar .3. The .front .and rear cross bars Aare .oppositely .grooved to .form race-ways which receive .crossed anti-friction lbearing rollers 4 by which .the .carriage is supported 'totravel over the' .top lplate of the machine .from .side to side thereof. The .bearing rollers 4 .also are received ,in oppositelygrooved race-ways in a front xed .guide rail .5 .and a rear .xed guide rail 6. The truck supports a platen frame comprising suit- 55, vvably connected end plates .7 united to the truck .tor case .shiftingmovement on the latter by parallel .links 8 and 9.. In the present instance the lower .case shift screw stops 10 are adjusted .up to hold .the platen frame and cylindrical 70 platen 11 carried thereby in the upper case position, upper -case type only being employed in the present instance.

,I prefer .to employ the usual front deilector plate ,12 rpivoted .at 1.3 to .the end plates 7 of the 75 platen frame and shiftable from the full line to the .dotted line position represented in Fig. 3. This .is .order to .facilitate the introduction of the Ylower ends of the Work sheets 14, which constitute a pack `ot sheets vto be written on, into a SQ space `vor channel 1'5 between a deflector plate .1.6 .and .the .lower surface of the platen. In the present .instance the deflector plate V16 constitutes .a part `of .a paper table 17 provided with .apertured earsl on the rear side .thereof to receive the yusual cross or .tie rod 19 by which the end plates '.7 .of the platen are connected. Curved spacing members '20 vare secured to the deflector 16 .near .the ends thereof and are adapted to .bear .against the bottom surface of the .platen in order to .maintain the deilector 16 spaced .apart `from the platen and thus provide the chan- .nel 15 .referred to. Adjustable cams '21 are secured .byscrews 22 to the usual cross 'bar v23 .that unites the side plates '7 of the platen frame. A 95 .loosening .of .the screws 22 affords .a rotative adjustment of the cams ,on the screws, whereas a tightening lolf vthe .screws 22 secure the cams in their .adjusted positions. These cams bear against the bottom of the deflector 16 and main- '100 tain it positioned with vreference to the platen.

In the present instance I provide Athe usual means for controlling the motion of the front deector 12 .from the full to the dotted line position shown in LFig. 3 and vice versa. Such means 105 comprise acrank varm24 .(see Fig. 2) operatively connected to .thedeflector l2 .and provided with .a laterally projecting pin '2.5 .received in a cam .slot .26 of .an `arm 27, pivo'ted .at `28 to va side plate T7.. Two of these .arms 27 ,are usually provided, 110

temporarily in the dotted line position shown in Fig. 3.

A link 30 is provided at its rear end With-a laterally projecting pin 31 adapted-to slide .in .a slot 32 in a bracket plate 33. The rear endV of the link 30 is thus supported for movement fore and aft of the machine and has a path of movement tc cooperate with the left-hand arm 27'and shift the latter forward, thereby moving the deiiector 12 from the full to the dotted line position in Fig. 3. The forward end of the link 30 is pivoted at 34 to a crank arm 35 which ter.- minates in a finger piece 36and is secured to a rock shaft 37.Y This rock shaft extends from side to side of the machine and passes freely through openings in two bracket arms 38 and 39.

The bracket arm 38 is detachably connected to the carriage being provided with a foot piece 40 apertured to receive the upper case shift screw stop 41 and to be clamped in position on the carriage by a nut 42 received on the upper end of said screw stop. The stem of a headed screw 43 passes through an opening in a second foot piece 43a on the bracket arm. 38 and engages in a tapped opening in the left-hand end bar 1 of the carriage. This bracket arm is apertured to receive and permit the rock shaft 37 to pass freely therethrough.

The bracket arm 39 is detachably securedto the carriage by screws 44 and is bifurcated at its rear end to straddle the tie rod 19. The rock shaft 37 ordinarily constitutesA part of a controlling means for a series of paper feed rolls for shifting them into and out of effective position. However, inasmuch as there is'no necessity for using these feed rolls in the present construction, they and their controlling companion devices are stripped from the shaft 37. The construction, however, is such that when the finger piece 36 is moved forward, it and the front deflector 12 controlled thereby, will be maintained in the effective dotted line position shownin Fig. 3, so as to leave both hands of the operator free to insert the pack of work sheets in the machine as will presently appear.

The construction thus far described is substantially like that employed in the Remington front feed machine except as hereinbefore pointed out and except that a single deflector plate 16 is employed instead of a double deiiector plate, and there is a slight change in the manner of supporting the combined paper table and deflector plate in the present instance. Moreover, the detachable bracket arms 38 and 39 have been added to the machine by me to provide an effective support for certain of the devices of my present invention.

A supporting bar 46 is secured at its ends by screws 47 and 48 to the bracket arms 38 and 39 respectively, and is maintained in an inclined position as indicated in Fig. 3. Spacing sleeves 49 are interposed between the upper face of the supporting bar 46 and a frontpaper table 50', whereas screws 51 pass through said sleeves and engage the paper table 50 to iixedly support it in place, as represented in Fig. 3. From this figure it will be seen that the paper table 50 is arranged Vprovide'the following devices on each slide.

substantially tangential of the platen at the front thereof Where work sheets supported on said paper table may pass around the platen into the channel 15 and be held in a bent condition snugly against the face of the platen at the printing line, as indicated in Fig. 5. In order to support thepack of Aworksheets in this position, and in a fixed relation to the printing line, indicated by the arrow a in said figure, I provide the devices which will now be described.

I.The paper table 50 is provided with upright slots 52 therein to receive supporting and guiding means provided on two slides 53. This is in order to guidesaid slides in their adjustment towards and from the. platen. These slides are alike in construction and the description of one will sufiice for both. Each plate-like slide 53 is provided with a depending under-cut stud 54 (see Fig. 6) adapted to extend through the companion slot 52 in the paper table to guide the slide along said vslot andf provide against an accidental detachment of the Yslidev from the paper table 50. A headed screw 55 carries an off-set pin 56. The stem of this screw an-d the off-set pin 56 pass through the associated slot 52 in the paper table and prevent a turning movement of vthe screw.

The stem of this screw` and also the pin 56 likewise extend throughopenings in the companion slide 53. of the'screw 55 and at its lower end bears against the associated slide or plate 53 thus binding it in its adjusted position when the thumb nut 57 is tightened. lA backing up of the thumb nut releases the slide and permits it to be adjusted up and down on the paper table.

Each slide 53 is provided with an impaling pin 58 projecting forward from the face thereofl and adapted to be received in openings in the upper edge portions of the work sheets 14, and thus support them at their'upper ends on the paper table 50. The work sheets are thus supported in a pack of twelve or fifteen sheets in superposed relation and `in` exact registration, it being understood that both of the slides 53 are adjusted up or down to the same height, as indicated in Fig. 1 of the drawings. The work sheets v14 are preferably ruled horizontally and provided with vertical columns for filling in various data under captions at the heads'of said columns such as Piece work, Day'work, Cash allowance, Bonus, Over time allowance, Total, etc., etc. The intent in the present instance is to provide a monthly or weekly record on each horizontal line of each 'work sheet'. At the end of each month or week, the entry on the various 'work sheets will be made 'on a given line, the next entry being at the end of the next month or week and so on.

In order to facilitate the proper adjustment of the slides 53Vtowards or from the platen so as to bring the proper line on each work sheet to posi- 1 tion at the printing line, I have provided a scale or'series of indices for each slide, so that the slides maybe successively registered with suc-v cessive indices on the scale and thereby quickly position the slides -to the proper positions to receive the work sheets for any given month or week. The markingsor 4indices on each scale are indicated at b, and an indicated mark or pointer c on each slide is 'adapted to' register with the marks on the scale and thus indicate the proper i positioning of the slides with reference to the l scales.

In order to prevent an accidental detachment of the work sheets from the impaling pins 58 I A thumb nut 57 engages the threaded end.

"Ti n.

holding device designated as a Whole by the reference numeral 59 is in the nature of a sheet metal slide movable up and down on its companion adjustable member or slide 53 into and out of effective position, the former position being shown in full lines in Fig. 6, and the latter position in dotted lines in said figure. It will be seen from this gure that each slide 59 has an inclined contact face 60 adapted to overlap and coact with the upper edge of the outermost sheet 14 on the pack of work sheets and to maintain it and the sheets beneath it from accidental detachment from the impaling pins. When, however, the slides 59 are moved upward to the dotted line position represented in Fig. 6, the work sheets are free to be withdrawn from or placed on the irnpaling pins. I prefer to spring press these members 59 to effective position and therefore connect each of said members with a contractile spring 61 anchored at one end on a pin 62. on the companion slide 53 and connected at its other end to an ear 63 on the companion holding member 59. Each holding member is held on its oompanion slide 53 and is guided and limited in its up and down movements thereon, by two headed pins 64 secured to the slide 53 and the stems of which are received in a slot 65 in the companion locking member.

When impaling the work sheets on the pins 58, it may be found desirable to retain the locking members 59 in ineffective position, and I have therefore provided latching means for this purpose. Such latching means comprises a latch 66 pivoted at 6'7 on the companion slide 53 and having an engaging nose that is adapted to be received in a locking notch 68 in the companion locking member 59. When seated in the locking notch, the latch will retain the locking member in its uppermost, ineffective, position against the force of the companion spring 61.

In' the use of the construction of my invention a series of superposed work sheets 14 are impaled on the pins 58 and the slides 53 are adjusted to bring the requisite line for entry on said sheets to the printing line. Assume, for example, the uppermost printed line beneath the printed headings on each work sheet is to be brought to the printing line, the slides 53 will be adjusted down to a corresponding position for this purpose and secured in such position by tightening the thumb nuts 57. The writing of the single line entry will then be effected on the outermost work sheet of the pack. The entered sheet will then be removed and an entry made on the work sheet beneath it, and so on until the pack of sheets is exhausted, when a new supply may be impaled on the pins 58. The next weeks or months entry will require an adjustment of the slides to the next higher index mark on each scale and a pack of work sheets having been introduced in the machine and impaled on pins 58, the entries on the sheets may proceed as before.

It will be seen that the paper dei-lector 16 below the platen will receive the lower end portions of the sheets of the pack and guide and maintain them in proper position whatever may be the positions of adjustment of the slides 53. Said deector will also maintain the sheets at the lower end portions thereof in proper relation to the platen so that the deflector 16 in conjunction with the impaling pins 58 and the holding means for the top of the work sheets will maintain said work sheets bent to conform to the surface of the platen and maintain the sheets snugly against the front face of the platen at and adjacent to the printing line for the proper entry of writing lines thereon.

In order-to properly direct the lower end portions of the Work sheets to the deflector 16 and prevent a lateral displacement of the pack with reference to the paper table 50, I have provided side edge'guides or gages 69 (see Figs. 1 and 3) whichV are secured to and project upwardly from the supporting bar 46 and coact with the pack of work sheets at each side of the paper table 50. These side edge guides or gages 69 are of sufficient depth to coact with the side edges of the entire pack of work sheets and accurately maintain the sheets against lateral displacement.
