CHECKWRITER.

To all whom t may concern:

lie it known that we, LIBANUS M. Tono and ilirrrion C. La MAY, both of Rochester, in the county of Monroe and State ot New York, have invented certain new and useful Improvements in Checkwriters; and'we do hereby declare the following to be a full, clear, and exact description of the saine, such as will enable any person skilled in the art to which the invention appertains to make and use the same.

This invention'relates to printing apparatus oi' the kind known as check protectors, or check writers, and more particularly, to that kind of check protecting machines which is provided with printing characters adapted in cooperation with a platen to print the value upon the check and at the same time rupture the paper so that the latter may absorb the ink applied by the printing characters.

It is of prime importance in such machines that the type be plentifully supplied with inl; so that the paper will be thoroughly marked. It is also characteristic of these. machines that they are frequently subjected to usage of an intermittent nature by inexperienced operators and without any regular attention, so that the supply of ink carried by the inhing rolls is orten allowed to become exhausted before it occurs to the operator to supply more ink, and checks printed by the machine in this condition are imperfcctly protected.

It therefore one object oiithis invention to provide a machine of this type having a fountain inlring mechanism of ink capable of keeping the printing characters abundantly supplied with ink suflicient for long periods of use so that impressions taken i'roin the machine will always be thoroughly inked and thus afford the best protection.

It is a further object of the invention to provide a machine oi' this kind, of a more automatic and self-contained character having mechanism :for automatically applying ink 'from the reservoir to the type characters in adjustable quantities and in proportion to the extent of use oi2 the machine.

Tlicse and other objects will more fully appear as the description proceeds, reference being hal to the accompanying drawings forming a part of the specification, in which Specification of Letters Patent.

In the'present embodiment of the invention the numeral 20 is used to designate, generally, the lower or base portion of the casing, and 2l denotes an upper casing portion having a hinged connection 22 (Fig. 6) with the base portion 20, so that the upper portion of the casing may be swung back to afford access to the interior parts. In operation these portions of the casing are firmly secured together by any suitable device, and, in the present instance, a screw 23 (Figs. a and 5) is shown for that purpose. The upper and lower portions of the casing are separated by a work receiving slot 24 below which, on the base portion 20, is a 95 printing bed 25 over which the work moves in its passage through the machine. The bed 25 has an opening 26 through which is adapted to be projected a platen wheel 27 (Figs. 3 and 8) rotatably carried by a yoke member 28 which is adjustably secured near one end of a shaft 29. This shaft is journaled in lugs 30 depending Jfrom the printing bed (Fig. 3) and nearits outer end the shaft has fixed thereto a hub 31 from which extends horizontallv an arm 32 adapted to contact with the printing bed to arrest the downward movement of the platen so that it lies normally with its top even with or 'ust below the upper surface of the printing d. The platen is urged into lowered or inactive position by a spring 33 (Figs. 3 and 6) attached at one end to the casing and at its other end to an arm 34 extending upwardly from the hub 31 and adapted at its upper end tol contact with the outline of an actuating cam 35 adjustably secured on a shaft 36 extending longitudinally of the upper portion of the casin and journaled at its ends therein. As the s aft 36 is revolved the cani 35, once in each revolution of the shaft, actuates the arm 34 and so raises the platen 27 into contact with type forms supported in the casing above, which will now be described.

Slidably mounted on the shaft 36 is a type carrier having a cylindrical surface 37 (Figs. 3', 4 and 8), and ends 38 having a sliding bearing on the shaft. Secured to the surface 37 is a type late 39 provided with a plurality of para] el type forms, indicated generally at 40, extending circumferentially of the carrier in parallel spaced relation so that they may be brought individually and selectively, by the shifting of the carrier along shaft 36, into position to coperate with the platen upon rotation of the carrier. The latter is provided with a key 41 sliding in a keyway in the shaft 36 and serving as a driv' connection between the carrier and shaft 'w en the latter is rotated.

The means for rotating shaft 36 comprise a gear 42 at the forward end of the shaft (Fig. 3) meshing with a gear 43 fixed to the inner end of a stub shaft 44 which is joui'naled in the upper portion of the casing and carries exteriorly thereof an actuating crank having a handle 45.

The type carrier is shifted longitudinally to select the type forms by means of an elongated yoke 46 provided with depending ends 47 rotatably and slidably journaled on the shaft 36 and closely engaging the ends of the carrier.

The means for shifting the yoke 46 comprises aplate 48 attached to a lug 49 on the yoke (Figs. 4 and 7) and extending through an opening 50 in the casing and carrying a handle 51. The plate 48 is extended horizontally to form a pointer 52 above a dial 53 on top of the casing which has niarkings thereon corresponding to the various type forms on the carrier. By means of the handle 51 the pointer 52 may be moved into alinement with any one of the markings on the dial, thereby shifting the carrier to bring the correspondin type form into position to cQ erate with ilie platen.

` he dial 53 is supported on a plate 54 carried' on a flange 55 extending upwardly from the top of the casing, and the plate 54 is' provided with an elongated slot at the edges' of .which the plate is turned downwardly to form flanges 56 serving as guides for a roller 57 secured upon the yoke 46 and serving to prevent rotation of the latter with the shaft 36.

The printing surfaces of the type forins and the platen are provided with coperating serrations which, as indicated on the platen in Fig. 3, preferably extend circumferentially of both members, and these serrations are adapted to mesh with each other, or register, during the printing Contact to disrupt the fibers of the paper and simultaneously print and feed it. As these serrations are comparatively small there is provided a means for brin ing the selected type form precisely into registering position with the platen, and for locking it in this position during the printing operation. Depending from the flange of the casing is a comb or rack 58 having recesses spaced to correspond with the spacing of the type forms on the carrier, and pivoted at 59 on a lug 60 of the carrier yoke 46 is a coperating dog 61 having a beveled end 62 adapted to be moved into locking engagement with the recesses of the rack 58. Dog 61 is normally held in lower or inactive position by a spring 63, in which position the bottoni of the dog contacts with the outline of a cam 64 on the end of the type carrier. This cam is so designed that as the type carrier is rotated the dog is moved into engagementwith the rack 58 just previous to contact between the type form and platen, and by means of the beveled surfaces of the dog and rack the type form is drawn accurately into position and locked until it passes out of contact with the platen when the cam allows the dog to be retracted, after which the carrier may be shifted longitudinally to select another form.

At the commencement of the printing operation the work is located on a table 65 (Fig. 3) sliding longitudinally upon guide rods 66 at the ont of the casing. As this table forms no part of the present invention a detailed description thereof is unnecessary. Attached to the upper portion of the casing and extending horizontally above the table is a plate 67 (Figs. 1 and 8) to which is pivoted at 68 a plate 69 provided with a gage opening 70 through which the line to be printed is sighted in adjusting the position of the work upon the table 65. The plate 69 is extended within the casing to form two spaced resilient lingers 71 bearing at each side of the printing line upon a small roller 72 rotatably journalcd on a plate 73 secured on the printing bed. The fingers 71 bear resiliently upon the work and serve to guide and hold it against inadvertent movement on the printing bed as it is fed forward by the printing touple, but as these fingers must be raised to allow the insertion or removal of the work the plate 69 is provided with an upwardly extending leaf 74 with which engages a hook 75 on a spindle 76 journaled in brackets 77 (Fig. 3) in the u per portion of the casing. The spindle 6 carries a fixed arm 78 (Fig. 3) which is pivoted at 79 to a plate 80 which extends upwardly and is provided with a plunger 81 projecting above the casing. By depressing the plunger 81 the pressure fingers 71 are raised away from the roll 72 so that the work may be freely inserted or withdrawn from the machine.

For applying the ink to the type forms there is provided a pair of short inking rolls 82 and 83. The type forms are adapted to print, some in one color of ink and some in another, and to this end are grouped according to color, as indicated in Fig. 3, where the reference character 40r designates type forms printing, say, in red ink, and the character 40b type forms printing in black ink. The ink roll 82 is provided for inking the forms 40h, and the roll 83 for inking the forms 401.

The roll 82, preferably, is rotatably mounted on a spindle 84 (Fig. 10) carried in a bracket 85 projecting from a sleeve 86 which is rotatably supported upon a round bearing portion on the angular rod 87. This rod extends longitudinally of the carrier yoke 116 and is rotatably journaled at its ends in

arms

88 and 89 extending from the yoke. Roll 82 is normally urged downwardly toward the type forms by spring 90, but its movement in this direction is limited by the contact of a lug 91 on the arm 88 with the end of a slot in the sleeve 86, see Fig. 10.

The roll 83, preferably7 is rotatably carried on a spindle 92 fixed in a bracket 93 which extends from a sleeve 94 slidably, but nonrrotatably carried by the angular section of the rod 87. The rod 87 projects beyond the supporting arm 89 and has fixed at its end an arm 95 (Fig. 7) which is drawn upwardly against a stop pin 96 by means of a spring 97 attached to the arm and to the yoke 46. By this means the roll 83 also is normally urged downwardly in position to contact with the type forms as the latter are rotated for printing.

Each of the inkmg rolls is detachably mounted so that it may be conveniently withdrawn for cleaning. To this end each of the

brackets

85 and 93 is provided with a bore, as indicated at 98, Fig. 10, in which the spindle of the roll is inserted, and the spindle is provided with a circumferential recess 99 with which is adapted to engage a spring actuated plunger 100 having a pin 101 projecting through a slot 102 in the bracket so that the plunger may be retracted and the roll with its spindle readily removedl from the bracket.

It is very advantageous m operation to maintain an inking roll of the proper color opposite the printing point so that the type form selected for impression upon the paper will inevitably receive a supply of ink dur ing its rotation toward the platen just previous to the impression. With this object in view a construction has been provided for moving the rolls automatically in cooperation with the selective movement of the carrier. Pivoted to the top of the casing is a plate 103 pressed downwardly by a spring 104 carrying at its lower edge a cam surface 105 having a high portion 106, and also a cam surface 107 discontinued to forni a recess at 108.` The opposite end of the plate 103 is curved at 109 to insure proper engagement with a pin 110 fixed to the sleeve 86 and adapted to engage the plate as the carrier is moved toward the left in Fig. 5. The sleeve 94 also is provided with a proj eoting member 111 adapted to engage with the cam surface 107 as the carrier is moved toward the right, as seen in Fig. 4. There is also provided a stop member 112 (Fig. fixed to the casing in position to engage the member 111 to limit the movement of the roll 83 toward the left, as shown in Fig. 4.

The roll 82 is long enough to span the small group of forms 40b so that this roll does not move longitudinally relatively to the type carrier, and as the carrier is moved to place one of the latter forms in printing position the roll 82 is moved with it and the pin 110 engaging the

surfaces

109 and 105 slides freely over these surfaces, merely raising the plate 103. As the carrier is moved toward the right, as seen in Fig. 4, to place one of the forms 40 in printing position, the roll 83 moves with the carrier, due to its frictional engagement with the rod 87, and the member 111 riding over the cam surface 107 engages the high portion 106 and comes to rest in the recess 108 which serves to retain this roll opposite the platen in position to ink any one of the forms 40t which is brought into printing position by the shifting of the carrier, and it will be understood that during this shifting movement the rod 87 slides freely through the sleeve 94. Vhen, however, the carrier is shifted to again bring the ink roll 82 opposite printing position the pin 110 raising the plate 103 releases the member 111 and the roll 83 which is moved toward the left (Fig. 4) toallow the roll 82 to take its place. Thus the roll 83 is automatically picked up, carried to printing position and retained there when printing with one of the type forms 40r, but is released and moved out of the way whenever the carrier is shifted to bring one of the forms 40b and roll 82 to printing position.

The casing is provided opposite the path of movement on the printing rolls with an opening 113 having a closure 114 pivoted at its bottom to the casing and carrying a small latching member 115, Fig. 3. This closure 114 carries a fountain inlnng device for each of the

rolls comprising sockets

116 and 117 in Which the inking devices are supported, and as these devil'es are the same in construction a description of one will be sufficient.

The ink reservoir or container is, preferably, a cylinder 11S adapted to slide vertically in the socket 117, and the reservoir has a circular opening or valve seat 119 in its bottom in which is adapted to rest a ball 120 serving to close the opening but projecting below the bottom of the reservoir so that it may be rotated by contact with the ink roll, or even raised from its seat thereby to permit the escape of ink through the opening 119. The reservoir 118 is provided with a screw cap 121, and a rod 122 having a threaded engagement with this cap extends through the reservoir into proximityv to the ball 120. By turning the rod 122 and so adjusting its vertical position, the distance of movement of the ball 120 from its seat is controlled to regulate the flow of ink. The upper end of rod 122 carries a finger 123 adapted to move between stop pins 124 over a scale marked on the cap as a convenient means for marking the position of adjustment of the controlling rod.

For filling the reservoir with ink the cap 121 is provided with an opening in which is threaded the closure 125. r1`he member 125 has a central recess 126 extending upwardly from its bottom and communicating with a small aperture 127 opening through the side of the member 125, just below its head. By slightly unscrewing the closure member 125 until the aperture 127 comes above the top of the cap 121 the air may be allowed to enter the reservoir 118 through the aperture 127, thus forming an air vent for the ink reservoir, which may be opened or closed as found desirable in the operation of the machine.

In order to adjust the lowermost position in the socket 117 of the sliding reservoir 118 so that the ball 120 will be in position to contact properly with the inking roll regardless of the amount of wear to which the latter has been subjected, the socket 117 is provided with a lug 128 in which is adjustably threaded a screw 129 having a flange 130 adapted to engage beneath the flange 131 on the reservoir 118. The screw thus forms a stop of adjustable height for limiting the downward movement of the reservoir 118. but the latter is free to be moved upwardly in its socket whenever the ball 120 is raised by the inking roll into contact with the controlling rod 122.

Referring to the modified form of ink reservoir shown in Fig. l2, there is provided, as before, a reservoir 1,18 having a valve seat 119 adapted to be closed by ball 120. Into the upper end of this reservoir is threaded a cap 132 serving as a supporting socket for a glass container 133 which is closed at its upper end by a cap 134. Threaded into the cap 135i, and also into the lower cap 132, is a tube 135 which serves to draw these two caps tightly into contact with the ends of the container 133, gaskets being provided to make the joints fluid tight. (.)penings 136 are provided in the lower portion of the tube 135 to allow the ink to flow from the upper to the lower container. Supported in the tube 135 by an adjusting thread is a controlling rod 137 exteiuling into j'u'oxiinity lo the ball 120 for controlling the amount of opening of the valve, and the. red 137 has screwed upon its upper end a finger 138 secured in adjusted position on the rod by means of a lock nut 13S) and adapted to move over an indicating scale upon the top of cap 131 between stop pins 1l() for convenience in adjusting the position of the controlling rod 137.

The cap 13-1 is provided with a filling opening closed by member 112 provided with an air vent 1-11 similar in construction and purpose to that described above in connection with the preferred form of the invention. This modified form of construction designed to be used for the purpose of increasing the fluid holding capacity of the fountain inking device, for use in machinosI where the output of work is quite large.

The operation of the machine will be readily lnnlcrstood from a brief explanation in connection with the above description of the construction. A check having been placed in proper position upon the supporting table of, the handle 51 ,is moved to position the pointer successively over the' various type forms desired to be impressed upon the paper, and after each such adjustlment the crank 15 is rotated to rotate the type cylinder and raise the platen into rolling contact with the particular type form selected for printing. The check is thus simultaneously printed and fed through the machine. i

During the shifting of the type carrier to bring the various type forms selectively into printing position, the inking roll of the color corresponding to the selected type form is automatically brought opposite the printing point, in position to roll against and ink the selected type form as it moves into contact with the paper, the other roll being moved aside. The ink reservoirs, in the present embodiment of the invention, are so located that whenever the roll 83 is moved from opposite the printing position yit is carried opposite its ink reservoir.

When'the roll is moved from opposite the printing position it is, for certain positions only of the type carrier, brought opposite its reservoir, this roll having fewer forms to ink and so not requiring to be supplied so often. When each roll is opposite its reservoir, the contact of the type forms with the roll at each rotation of the carrier raises the rollv slightly, as shown in Fig. 9, bringing it into contact with the ball 12() so that the latter is rotated, and carries a film of ink from the reservoir to the roll, or else the ball 120 is raised slightly from its seat permitting a somewhat larger quantity of ink to be carried by it to the inking roll, depending upon the position of vertical adjustment of the rod 122. Vhen the ball 120 is raised by the inking roll into contact with the rod 122, the reservoir 118 is adapted to rise in the socket 117 to prevent excessive pressure between the inking roll and the ball 120. By means of the'adjusting screw 129 the reservoir 118 may always be supported in such a position that the inking rolls will contact with the ball when they are raised by engagement with the type, regardless of any variation in size of the rolls due to wear.

The supplying of ink to the rolls of a check Writing machine whenever they become too dry to aord a protective impression of the paper, and with just the right quantity of ink, is the most important and the moet troublesome feature of theoperation of a machine of this kind. This invention Icombines with a check writing machine a mechanism which attends to this requirement automatically by keeping the rolls uniformly and constantly supplied with the proper quantity of ink in proportion to the amount of printing done by the machine, and without attention from the operator over long periods of use, thus adding very greatly to the utility and efficiency of the machine.

Hating thus described our invention, what we claim as new and desire to secure by Letters Patent is 1. The combination of a printing couple comprising a rotatable type carrier and a platen, the members of said printing couple having a relative movement to bring various type forms on the carrier, selectively, to a common position for coperation with the platen, and having also a relative printing movement to impress the selected type forms upon the work; a fountain ink container; an inking device for applying ink to the type forms; and means for supplying ink from said fountain container to said inking device actuated automatically by the rotary movement of said type carrier.
