PRINTING-MACHINE.

Specification of Letters Patent.

Patented Oct, 15, 1918s Application filed July 10, 1917. Serial No. 179,636.

To all whom it may concern: Be it known that I, HENRY J. PLANT, a citizen of the United. States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful, Improvements in Printing-Machines, of which the following is a specification.

The present invention relates to printing machines, and more particularly to the type in which the workis fed in the direction of the printing line by a movement in the printing member to carry the work along with said member, an object of this invention being to provide a construction, in which the printing member moves relatively to a platen, while cooperating with the latter so as to shift the work on the platen without any movement in such platen. Another object of the invenstion is to provide in a construction operating as mentioned, cotiperating faces on the platen and the printing member so formed that the Work is held to the printing member while permitted to move freely on the platen. An-

other object of the invention is to provide in a rintin machine in which the rintin p a element moves in the direction of the printing line, a simple form of mechanism for moving the laten toward the printing memher and hol ing it in such position niitil the -30 end of the feedi'ng movement of the printing member is completed.

To these and other ends the invention consists of certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings Figure 1 is a" horizontal section through a \printing machine embodying the present invention; v

' Fig. 2 is a vertical section through such machine;

Fig. 3 is a section on the line 33, Fig. 2; Fig. 4 is a section on the line H, Fig. 3; Fig. 5 is a fragmentary section showing thfia pllaten in coiiperation with the printing w ee Figs. 6 and 7am, respectively, afplan and a sectional view Of the platen; and

Fig. 8 is a detail view, showing the type of one of'the printing lines enlarged.

The invention is, in this instance, embodied in what is known as a check writer, or a machine for writing words into checks, or other negotiable instruments, to represent an amount for which said instrument will be payable. In the illustrated embodiment there is employed a printing element or member 1, in the form of a type wheel. having on its periphery a plurality of parallel lines 2 of type, each line printin a word which maybe combined with war s printed by the other line, to write into a check any reasonable amount. In this instance, the type lines extend parallel with the axis of the printing wheel 1, and the latter is mount ed on a noncircular shaft 3, so as to move in the direction of the axis of the shaft, but to turn with such shaft The shaft is preferably journalcd in the opposite sidewalls of the overhanging portion 4 of the casing, the

overhanging portion projecting over a worksupporting plate 5 on the base .6 of the casing, from the rear edge of said work-supporting plate. A bottom plate 7 is provided on the overhanging portion and this bottom plate has an opening 8, over which'any one of the lines of type 2 on the printing member 1 may be presented by turning the shaft 3 to move the lines transversely of their lengths. The turning of the shaft may be effected by a hand wheel 9 arranged on the shaft on the exterior of the overhanging portion, said hand wheel having a dial wheel 10 integral therewith for cooperation with a fixed dial or indicator arranged on the casing. The characters on the dial 10 correspending with the words on the printing wheel, so that when anycharacter on the dial is brought opposite the indicator a Word corresponding to said character is positioned above the opening 8.

For cooperating with the printing element or member 1 an ink roller 11 is provided. This roller may have flanges 12 at opposite edges cohpe'rating with the said face of the wheel 1, so that the roller will move with the printing wheel 1 on an elongated shaft 13 extending parallel with the shaft 3. The shaft 13 may be supported by a swinging arm 14-, on which a spring 1% acts The printing is effected by moving the work, which has been supported upon a table 5, upwardly through the opening 8 into engagement with the type line disposed above said opening. This movement of the Work is produced by a platen 16, which operates through a slot in the table 5 mounted for vertical movement within the base 6. In this instance, the platen is embedded in a block 17 movable at its ends in guides 18 on opposite sides of the base 6, the block 17 having depending portions 19 at opposite ends provided with inwardlyextending pins or projections 20, which lie in close proximity to horizontal guides 21. On these guides 21 a slide plate 22 is movable, said slide plate having notches 23 at opposite sides which receive the pins or projections 20 when the platen is in its lowermost position. WVhen the slide plate moves in one direction an inclined wall 24 of each notch or recess 23 acts as a cam which passes beneath the adjacent projection 20 and elevates the latter so as to move the platen l6 upwardly into contact with the type line 2 above the opening 8. The platen is so held until the projections 20 reach one edge of the slide when the platen will be depressed by the action of the spring arms On the return movement of the slide 22, cam faces at one edge of the slide. will engage the projections 20 and shift the plate 22 away from its guides 21, thus permitting the plate to return to the position shown in Fig. 2, without affecting the position of the platen 16. In order that the cam plate 22 may partake of the sliding and lateral movement, it is preferred to mount the latter at one end of a rod 27, winch is guided at 28 in the rear wall of the casing to partake of a longitudinal and slight rocking movement. A coil spring 29, anchored at one. end at 30 to the base 6, and at the other end at 31 to the slide, tends to hold the slide plate 22 toward the mlides 20. and also to shift said slide 22 in one direction on the guides. The movement of the slide in the other direction preferably etl'ected by a crank arm 32 arranged on the (.Yl'tllnl oi the casing on a rock shaft 33, which, by a slotted arm 34, connects with a. pin 35 on the rod 27.

Movement of (in printing member in the direction oi the printing line may be ell'ected in any suitable manner. in this instance. a slide 36 is movable on the guides 37,- which. are parallel with the axis of rotation of the printing member, the movement of the slide being produced in this embodiment by a .slotl'ed arm 38 mounted upon a vertical rock shal l ll) and engaging a pin ii on the slidc. The lower end ol' he rock aha l't has a :dotted arm 42. which receives a pin iii on the rod 27. so that when the rod 27 is moved roan wardly by the crank handle I32, the shalt 40 will be lUtliLLl and transmit motion to the slide 36 which, in turn, transmits movement to the prnlting member.

Connection between the slide 36 and the printing member is so constructed that the printing member notwithstanding a constant or uniform movement in the slide 86, will be moved "ariable distances corresponding to the lengths of the words on such printing member. This is effected by providing the printing member with a plurality of grooves or notches H in its periphery, the ends 45 of these notches serving as stops which are located at diiferent distances from the common plane formed by one side of the printing wheel. The slide 36 has a projection 46 and a projection 47, the projection 47 cooperating with one face of the printing wheel, while the projection 46 is adapted to enter the grooves -14 in order to coijperate with the shoulders or stops 4-5 formed by the ends of said grooves. It is apparent that, when the slide 36 is .moved in a direction to feed the work, the

projection 46 will move in one of the grooves 441 without producing any movement in the printing wheel until the end of the groove is reached, after which the projection Will cooperate with. such end and shift the printing wheel a distance corresponding to the worlr printed. Upon the return movement of the slide 36, the projection 47 will cooperate with the printing wheel and return the latter to its initial position. '10 the end that the printing wheel will not shift with the slide, until the projection 46 is engaged with an end wall 45 of the slot, a spring arm 48 is mounted on a slide. and acts on the printing wheel in a direction to hold the latter in its initial position, until a stop 45 has been engaged by the projection 46..

In the operation of the invention, thework is placed face upward upon the Work support and beneath the opening in the overhanging portion in the casing. The printing wheel is'turned by means of the thumb wheel 9 to present the desired word at the printing point, the indicator 10 being em ployed for locating this word on the type wheel. The crank handle 32 is now moved forwardly, thus drawing the rod 27 to the rear and causing the platen l6't0 be elevated due to the engagement of the projections 20 with the slide After the work has been pressed against the printing wheel to pro duce the printing, the projection 46 on the slide 256 engages a stop 45 formedby' the inner end of one of the slots 44;. This causes the. type wheel 1 to move with the slide 36 a distance corresponding substantially to the length of the word which has been printed.

grooved upper face of the platen; Owing to vthe fact that the type faces penetrate the paper, the ink supplied to the type Wheel by the roller 11 is caused to be absorbed by the and this renders the erasure of the printed matter impossible, About the time that the printing wheel 1 has reached the limit of its -feeding movement, the platen 16 lowers, due to the fact that the projections 20 pass beyond the end of the slide 22. With the release of the handle 32 the printing wheel 1 returns to its normal position, and the slide 22 moves forwardly over the projections 20 until such time that said projections shall enter again the notches 23, so that. the parts will assume the positions shown in i Fig. 2, the return of the parts being effected which the printing wheel moves in the direotion of the printing line over the platen for feeding the work.

I believe myself to be the first to feed work in a printing machine by the movement of a printing member in the direction of the printing line'over a platen which will simultaneously engage the work throughout the length of the printing line, the length of the platen being such that it will maintain its engagement with the printing element or member during the movement of the said element or member over the platen.
