TYPEWRITING MACHINE.

Application led Harch 3, 1921, Serial No. 449,467. Renewed December 21, 1922.

T 0 all whom t may concern:

Bc it known that I, Jnssn A. B. SMITH, av citizen of the United States, residing in Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to paper-carrying devices of front-strike -typewriting machines. Y

One of the objects of the invention is to facilitate the typing of short work or billsheets calling for entries upon only two or three lines, as in the case of gas bills. `Where but a few entries are to be made on a bill-sheet, and a large number of sheets are to lbe typed, it is not satisfactory toinsert the sheets from the rear and adjust them to typing position, as these operations conf sume a great deal of time in proportion to the amount of actual ty ing. The present invention simplifies the introduction of the work-sheets and their adjustment to the printin position.

For t lis purpose, in carrying outthe present invention, the work-sheets are inserted at the front of the platen bottom end foremost. Their upper ends are collated upon,

a table adjustably mounted on the machine in such position that, when a work-sheet is aligned at its to and side edges on ages carried by the ta le, the work-sheet will be properly positioned at the printing point. pince the headings (the distance from the upper edge of a sheet to the iirst line to be typed) of various types of work-sheets may vary 1n length, meaps are provided for adjusting the end gage of the Acollating table through a wide range longitudinally of the work-sheet. The variations in the lengths of work-sheets may require the adjustment of the end age through full line- .spaces, or through a raction of a line-space, or through several full line-spaces and a Vfraction of Va line-space. It is an object of this invention to provide for such adjustment.

The work-sheets having been adjusted in position, means are provided whereby' the sheets may be typed upon one, twogor three lines. For this purpose,v the end gage of the collating table is mounted upon-a slid-` able plate adapted to'be moved upwardly and held in position at line-space intervals, v

the sheets, which are held to the table by sprlng-ngers, being moved up tothe end gage by hand. By the above-described means, a simple, rapiduand efficient method of typing short work-sheets is obtained.

Other features and advantages will here= inafter appear.

In the accompanying drawings, Figure 1 is a front view of a machine with the invention applied thereto, onlyT the necessary co-operating parts of the machine being shown.

Figure 2 is a lvertical section taken` on the linel 2-2 of Figure 1. l

In the Underwood standard typewriting machine, a platen 10 is fixed upon an axle 11 journaledl in the end walls 12 of a shiftable platen-frame forming part of the usual typewriter carriage. Adapted to be mounted at the front of the p aten is a front collating table 19 whose mounting com rises three portions, a central portion 20 an end ' portions 21 and 22. Tie-members 23 and 24 are provided to unite each end of the central portion with the-adjacent end of an end porV tion. The ends of the central portion are fastened to the tie-members by sets of screws and 26, lwhile the end portions are fastened to the tie-members by 'sets of screws 27 and '28. The end portions have upstanding members 30 and 31 adapted to overlie longitudinally disposed bars 32 and 33 fixed to the platen-frame by brackets 34 mounted upon tie-rods .35 and Walls of the platen-frame and upward extensions 36. The outer edges 37 and 38 ofl the end portions are down-turned' and adapted lto` engage the outer edges of bars 32 and 33. The bars 32 and 33 are Arovided with vopenings 40 and 41 positione at 11nespace intervals apart and adapted to be engaged by studs or screws 42 and 43 passing through the members 30 and 31. It is thus possible to slide the mountin for the table long said ars toward or 19 longitudinally a number of away from thej platen for an 36 ixedlin Vthe end.

full line-s aces within the llmits of the bars, andl t en secure the mounting in adjusted position by means of said studs or screws 42 and 43.

To allow for free sliding motion of the collating table upon the bars without any binding action or too great lateral play, the j distance between studs 42 and 43 can be varied b means of screws 28 operating in lateral s ots 44 in end portion 22. Y

A. work-sheet may be inserted at the front of the platen bottom end foremost until the first line to be typed is at the printing point, the upper end of the sheet resting upon the collating table. The latterrmay be moved toward or away from the platen until an upper end gage 45 comes in contact with the upper end of the work-sheet. The table is then fixed in position by screwing the studs 42 and 43 into the co-operating openings in bars 32 and 33. Thereafter, worksheets inserted at the front of the machine to receive corresponding entries need only have their upper ends positioned in contact with the upper end gage 45, and the sheets will be properly positioned to type the first line. Tt frequently happens, however, that when a work-sheet is adjusted so that the first line to be typed is at the printin point, the upper end gage 45 cannot be rought into contact with the upper edge of the sheet, because the table moves full linespaces forwardly or rearwardly while the sheet terminates at a fractional line-space position between two full line-space positions of the table mounting on the bars 32 and 33.l Means are, therefore, provided for moving the table toward or away from the platen a fractional part of a line-space. Said means comprises the sets of screws 25 and 26 which operate in longitudinal slots 46 and 47.

When a new work-sheet is inserted bottom end foremost and adjusted so that the first line to be typed is at the rinting point, the collating table is adjusted) along the bars 32 and 33 until the gage 45 contacts with the upper end of the sheet. Tf the sheet terminates between two full line-space -positions of the table on the bars, the table is fixed on said bars at the nearest full linespace position, and the fractional adjustment is accomplished by the screws 25 and 26 operating in the slots 46 and 47. The table is then in position to facilitate the adjustment of any number ofzsuccessive sheets of the same size. To aid in positioning the sheets rapidly, an edge gage is provided on one side. Tn this case, an edge gage 50 is mounted at the left side, and comprises a gage-member 51 and a fiat member 52 mounted and slidably adjustable on the end portion 21 by means of screws 53 operating in lateral slots 54.

ere more than one line is to be typed,

' means must be provided for suitably gaging Ysaid work-sheets at line-space intervals.

the end e central This is accomplished by mountin gage 45 on a slidable late 6.0.

portion 20 of the col ating table comprises 62 is xed to the rear a rear bar 61 and a top plate 62. The plate ar 61 by screws 63 maaier countersunk in the top late, the countersunk portions of the p ate 62 providing clearance between the top plate and the rear bar for the slidable plate' 60. The latter has cut-out portions 64 adapted to clear the screws 63 Awhen it is moved upwardly. For moving the slidable plate upwardly, a fingerpiece 65 fixed thereto is moved toward the left. Pins 66 fixed to the top plate 62 project into cam-slots 67 provided with dwells 68 atvtheir ends. When finger-piece 65 is moved to the left, plate 60 rides upwardly on pins 66. A sprmg 70, fixed to the rear bar, is provided with a pin 71 adapted to project through an opening in the rear bar and press against the slidable plate. Three openings 7 2, 73 and 74 are provided in the plate 60 corresponding to the lowest and two raised positions of the plate, each raised position being one line-space above the previous position. The pin 71, lodging in the openings 72, 73 and 74, will hold the plate in each position, and, in addition, the pins 66, riding on dwells 68, will hold the plate 60 firmly in lowest and highest ositions. Where more than three lines are to e typed, longer cam-slots 67 and more openings similar to 72, 73 and 74 may be provided. Spring lingers 75, attached to the near plate and bent over to contact with the front plate, aid in holding the work-sheets in position. The loop of the spring is suiciently large not to interfere with the upward movement of the slidable plate.

Variations may be resorted to within the scope of' the invention, and portions-of the improvements'may be used without others.
