To all whom it may concern:

7 In said drawings: 1 Be it known that we, NELSON WHITE and Figure 1 is a right side view of an illus- CHARLES G. TIEFEL, citizens of the United States of America,.and residents of the city of Rochester, in the State of New York, new and useful Improvements in Checkwriters; and we hereby declare the following to be a full, clear, and exact description of the same.

While the invention is capable of applicounty of Monroe and cation to a wide range of printing devices of various kinds, it is peculiarly applicable to machines of the kind known as check writers or check protectors for printing'on checks and other documents, words or characters representing amounts to prevent raising or. altering to make the papers appear to have a nall intended.

any business concerns have come to use large check blanks known as voucher checks and still others have their checks printed in sheets, each sheet containing a number of check blanks. It is desirable in using checkwriting and protecting machines to be able to print or emboss. the amount at any point or. such voucher checks or upon the different checks in a sheet without first tearing the checks apart. A

Attempts have been made in the past to produce machines capable of printing on large voucher checks or sheets of checks, but, in doing this, the work supporting beds of the machines have simply been made larger.

This has resulted in making the machines large and cumbersome, whereas one of the most desirable features such machines can have is to be small and compact.

The objectof this invention is to provide means whereby small, compact machines of the'kind mentioned may be so constructed as to permit using them to print at any point on even a very large sheet'of paper.

With this and incidental objects in view, the invention consists in the novel construction and arrangement of parts, the essential elements of which are set forth in appended claims and a preferred embodiment of which is hereinafter described with reference to the drawings accompanying and forming a part of this specification.

have invented certain greater value than origitrative machine with the invention applied thereto.

Fig. 2 is a detail with parts broken away and others in section to show features of the invention.

F ig.- 3 is a longitudinal section through the illustrative machine.

Fig. 4 is a section on the line 4 4 of Fi 2 looking in the direction of the arrows.

tated in a general Way, the inventionprovides means whereby 'a sheet of paper to beprinted upon may easily be rolled up in the machine paper so that an impression can be made by a printing couple upon any part of the sheet. The machine to which the invention is shown by the-act of inserting the.

applied in the drawings is a very simple one and is intended only to illustrate how the invention may be applied generally to checkwriting and protecting machines. As will be more clearly apparent later on, the exact form of the anism for operating it is not essentialto the lnvention.

The illustrative machine has an outside I casing supporting and inclosing the mechanism. Rotatably mounted in this casing is a shaft-11 having fastened thereto a type drum 12'upon the periphery of which are lines of type 13 for printing various legends. Fastened to the right hand end of the shaft 11 is a knob 14 by means of which the type drum may be turned to position any, one of the type lines 13 above a laten orimpression member 15. -Rigid wit the knob 14 is a dial or indicator 16 which serves in connection with an index 17 to guide the operator in setting the type drum.

The impression member or platen is supported at its ends by arms 21 journaled on a rod 22. Engaging the underside of the platen" 15 are balls 23 loosely supported in a cross bar 24 supported at its ends by arms 25 of a platen operating lever pivoted on a rod 26. Only one of the arms25 is shown in full inFig. 3, the other being broken 100 away, but it will be clear that there is one printing couple and mechof these arms at either side of the machine and that they branch from a common arm 27 extending toward th s rear of the machine.

' Springs 28 maintain engagement between the ular y to draw the platen down to the pos1-' tion shown after a printing impression has been taken. i

Pivoted to the rear end of the'arm 27 of the platen operating lever is one end of a link 31. The other end of the link 31 is.

pivoted to an arm 32 integral with an operating lever 33 and extending through a slot 34 in the rear of the casing. The operating lever 33 is pivoted at 35 between lugs 36 on the casing. It isclear that if the lever 33 is pressed act as a toggle to depress the rear end of the platen operating lever, thereby swinging thev bar 24 tension of springs 37 to engage the platen a 15 with the positioned type line 13. It is yoke 42' carried by a removable plate 43 nor- .mally fastened to the top of the machine casing. Rotation of the type drum 12 to select ty e will cause the type to take from the ro ler 41 whatever ink they require for printing.

In order to receive and guide the work between the printing couple, that is, between the type drum 12 and the platen 15, the easmg may be slotted as shown at 44. The sides of the casing are provided with cir cular openings providing a tubular clearance across the machine and the work receiving slot 44 enters these circular openings in an approximately tangential direction.-

. It 1s clear that, as so far described, if a sheet of paper is thrust into the machine through t e slot 44, the tangential relation of the slot an circular openings 45 will cause the paper o roll up automatically in said openings and that, with a reasonableamount of care, quite a Wide sheet might be inserted in this way and adjusted laterally of the machine so as to be printed .on at any desired point. An indicator 46 on. the casing serves to guide the operator in placing the paper to have the. printing come on the .proper line and a similar indicator (not 1 shown) on the front of the machine serves to indicate the correct lateral adjustment of the pgper. A shield 47 extending across the mac ne is shaped to conform to the outline of the opemngs 45 and serves to prevent the paper from striking the type 13 in case the paper should happen tobuckle,

laten-15 and balls .23 and serve partic down the arm 32 and link 31 will and platen 15 upward against thev While the construction as described so far would be satisfactory within certain limits,

means have been provided to make possible the use of larger sheets by relieving friction 1 between the paper and the edges of the circular openings 45 and at the same time affording a certain accommodation to the adually increasing size of the roll of paper in case the paper should be given several turns in winding.

This means comprises a number of antifriction rollers'51 having their peripheries extending into the circular openings 45 far enough to be engaged by the work when the work is pushed inthrough the slot 44. The rollers 51 are loosely supported on studs" 52 on circular plates 53 on the sides of the machine; As shown in Fig. 2, the portions of the studs forming bearings for the rollers 51- are enough smaller than the openings through the rollers to allow the rollers to have play radially on the studs and the heads of the studs are large enough to prevent the rollers from being laterally displaced.

Inclosmg the studs ing shield or cap 54. This cap 54 has and rollers is a finishformed on it ears 55 and the roller supporting plate 53 has similar cars 56. two sets of cars are so positioned that when the parts are in proper relation, through the two pairs of cars will coincide and provide a convenient means for attaching the devices to a machine, Both the cap- 54 and the plate 53 are slotted as at 57 in alinement with slot 44 's0 as to provide an entrance or clearance through which the work may be inserted.

The addition of he rollers 51 provides a means whereby the frictional resistance to the movement of the work is minimized and even with a paper which is not very stiff, the simple act of the slot 44 will cause quite a large sheet to be rolled up automatically in the machine. If

the paper makes several turns, the rollers 51 are free to move radially on their support- .ing'studs 52 to compensate for the increase in size of the roll and thereby offset, to a certain extent, any' tendency the paper may have to pinch and bind as it is being rolled While the form of mechanism herein shown and described is'admirably adapted to fulfil the objects primarily stated, it is screw holes thrusting the paper through The to be understood that it is not intended to confine the invention to the one form of embodlment shown and described for it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.
