To all whom it may concern Be it known that l, Guanine H. SAMPSON, of Rochester, in the county of Monroe and State of New York, have invented a newand useful Improvement in Printing-Machines, which improvement is fully set/forth 1n the following specification and shown in the accompanying drawings.

The present invention relates to printing machines and an object thereof 1s to improve the mounting of the platen in that type of machine in which the platen has a serrated face for engagement within grooves on the I printing surface for the purpose of bruising or puncturing the paper durlng the printing operation.

Another object of the invention is to improve that type of printing machine having a rotary type wheel so that all play in the type wheel is eliminated during the printing operation.

A still furtherobject of the invention 1s to simplify the construction of the feed ng mechanism of a printing machine in WhlCll the work is given a variable movement to I correspond with the matter printed.

A still further object of the invention is to provide a work gage which is so mounted with relation to the work support that the work cannot pass under the same, provision preferably being made to permit the gage to be quickly adjusted and to be held in its adjusted position by a single operating member.

To these and other ends the invention consists in certainv 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 top plan view of a check writing machine embodying the present improvement, a portion of the indicating means being cut away in order that the work ga e, may be seen; Fig. 2 is a section on the line aa, Fig. 1; Fig. 3 is a section on the line b b, Fig. 1; Fig. 4: is a vertical sectional view of the gage operating member; Fig. 5 is a horizontal section on the line co, Fig. l; Fig 6 is a vertical sectional view on the line (ll-J, Fig. 1, the handle or operating member being removed; Fig. 7 is a section on the line e-e, Fig. 6;

Fig. 8 is a detail view showing the platen terior parts; and Fig. 10 is a section on the line d-d, 1 looking in a direction opposite that of ig. 6.

Referring more particularly to the drawings, 1 indicates the base frame of the casing which is preferably hollow and is closed by a bottom plate 2. Within this base frame a platen 3 is preferably movably arran ed to operate through an opening in the wor support 4 which forms a portion of the top of the base frame 1. The platen is preferably arranged on one end of a lever 5 which carries segmental trunnions 8 turning in bearings 9 below the work support 4:, this platen carrying lever extending rearwardly 1n the base 1 and being operated by a mechanism which will be hereinafter described. The platen 3 is preferably adjustably mounted on the lever 5 in order that its serrations 10 may be made to cooperate properly with the printing surfaces. In this instance, the lever 5 is provided with a transverse groove 11 opening at its opposite ends at the sides of the lever. The platen 3 is a block the opposite sides of which closely hug the side walls of the grooves 11. A screw 12 engages the platen 3 at the center thereof and extends loosely through the bottom wall of the groove 11, its head cooperating with the under face of the lever to limit the upward movement of the platen but permitting the tilting and also :the longitudinal movement of the platen within the groove. The tilting movement may be effected by two screws 13 operating through and having screw threaded engagement with the bottom walls of the groove 11, but merely bearing against the under surface of the platen so that the turning of the screw efiects the tilting of the platen about the screw 12 as a fulcrum. The nuts 14 operate on the screws 13 to hold them in their adjusted positions. Longitudinal movement of the platen is effected by two screws 15 which have screw threaded engagement with opposite ends of the platen and lie in the groove 11 and have their heads cooperating with the side walls of the lever 5 in proximity to the ends of the groove 11. It is apparent that the adjustment of the screws 15 will cause the longitudinal movement of the platen 10 in its groove 11 while the screws do not interfere with the vertical adjustment of the platen.

Arranged above the base frame 1 is an upper casing member 16 which is supported bodies the rotary type wheel 17 having lines of type'18 arranged thereon, the types being provided with grooves to receive the serrations of the platen 3, the platen being adjustable as before described in order that I the proper matching of the grooves in the rality'of spaced teeth type wheel and the serrations of the platen may take place. In this instance, the type wheel turns on the shaft 19 and has a gear wheel 20 rigid therewith in order to be driven or rotated from the oscillatory hollow shaft 21 which carries a beveled gear 22 meshing with a beveled gear 23 which is coaxial with and. is secured to a gear 24 that in turn meshes with the gear 25 meshing with the gear 20. The oscillatory hollow shaft 21 extends vertically through the casing 16 in'rear of.the work support 4, its upper end being provided with a pocket 26 which is slotted at 27 to permit the operating lever or member 28 to be pivoted thereto at 29 and extend into the same in order that its inner end may cotiperate with one end of a lever .30, the other end of said lever cofiperating with the plunger 31 extending through the hollow shaft and cooperating at its lower end with an adjusting nut 32 which is carried by the platen lever 5, in order that the operatinglever 28, which is swung laterally to position the typewheel may also have another movement which shifts the platen to-eflect the printing operation after the type wheel has been thus positioned. A spring 33, anchored at 34 at its upper end, is connected at 35 to the rear end of the platen carrying lever in order to hold the platen in its lowermost position and at the same time to elevate the plunger so that the operating lever or member 28 will occupy the position shown in the matter which will be printed by the type on the type wheel. Below this dial a plu- 38 is arranged in order to, permit the operating lever 28 to move downwardly between them to hold such lever against lateral movement while it is being moved vertically for the purpose of effecting the movement of the platen.

With the object in view of preventing any movement of the printing wheel during the printing operation, a locking device is employed comprising preferably a pivoted dog latter but,

- this end a member 49 39 pivoted at 40 within the overhanging extension of the casing and having a nose 41 which is adapted to be wedged between the teeth of the gear 25, the latter having a number of spaces between its teeth corresponding to the number of lines of type on the printing wheel. During the rotation of the printing wheel, this dog lies out of cooperation with the gear wheel 25 but, upon' the movement of the plunger 31 a resilient connection such as'a spring arm 42 extending from the platen lever 5 and enga g with the dog 39 at 43, shifts the we geshaped nose 41 of the dog into engagement with the gear 25, and, as the latter meshes directly with the gear on the type wheel. the type wheel is held against movement while the platen is being moved.

In connection with the machine, a feed- 4 ing mechanism may be employed which feeds the work, after the printing operation a distance corresponding to the length of the matter printed by the printing mechanism, it being understood that the ing mechanism necessarily prints di erent words of various lengths in order to erform its functions as a check writer. his feeding mechanism is preferably in the form of two knurled wheels 44 arranged on a shaft 45 within the base 1 so that they project through openings in the work support in order to engage the work. Upon the shaft 45 a ratchet wheel 46 is rigidly secured. Also arranged upon the shaft to turn loosely thereon, is a swinging arm 47 which carries a spring-pressed pawl 48 for coiiperation with rintthe ratchet wheel 46. It is one direction by the arm 47, it will ride over the ratchet wheel without affecting the when moved in the other direction, the ratchet wheel will be compelled to travel with the pawl and the arm 47.

The feeding mechanism ma be controlled by the platen operating mec anism and to the lower end of the plunger 31 and has its outer end guided on the link 50 which issurrounded by a coil spring 51 arranged between said ded portion and a shoulder 52, thus provi g a resilient connectionbetween the platen operating mechanism and the feeding mechamsm. The link is pivoted at 53 to an arm 54 of a three-armed lever which is pivoted at 55 on the top of the base 1 within the upper casing. The lower arm 56 of this three-armed lever extends downwardly and is connected by a link 57 with the swinging arm 47 so that, when the plun er 31 is moved downwardly, it presses 51c member 49 downwardly transmitting a movement. to the three-armed lever, causin the latter to shift the swinging arm 47 an carry the pawl 48 over the. ratchet-wheel'46 without shifting said wheel. Upon thereextends laterally from nitrate turn movement of the three-armed lever due, to the release of the plunger 31, the swinging arm causes the pawl 48 to turn the ratchet wheel and in this way to feed the check for another printing operation.

The amount of feed of the feeding device may be determined by a gaging means which is preferably in the form of an irregularlyshaped or shouldered hub 58 preferably integral with the gear wheel 25, the shoulders thereon forming stops for engagement by a laterally-turned end 60 on the third arm 61 of the three-armed lever. It is apparent that, when this three-armed leveris moved on the movement of the plunger 31, its lat which of the shoulders is in its path of movement. It is also apparent that the positions of these shoulders must'correspond to the lengths of the words on the rotary type wheel in order that the movements of the three-armed lever will correspond with the lengths of the lines on the ty e-wheel so that the swin 'ng arm 47 and t e knurled wheels 44 will ave movements to agreewith the lengths of the words on the type wheel.

The check may be held firmly to the feed wheels 44 by means of two wheels 76 each cooperating with one of the wheels 44 and carried by a frame 77 which has a finger piece 78 by which the wheels 76 are moved away from the feed wheels 44 against the action of a spring 79.

There may be associated with the work support a work gage which determines the posltion of theicheck with relation to the printing mechanism. This gage is preferably arranged to one side of the overhanging casing andis preferably in the form of a T-sha'ped member formed from sheet metal, thecross piece 62 being bent into inverted' U-shape and having near its ends depending projections 63 arranged-to operate in parallel grooves or depressions 64 formed in the work support 4. The other arm 65 of the T-shaped member may be slotted at 66 and may operate within a way 67 formed in a projection 68 at the rear of the work support.

For the purpose of adjusting the gage and holding it in its adjusted position, there may be provided an operating member 69 preferably in the form of a rotary hand piece turning on a shaft 70 which has screw threaded engagements at its lower end with the projections 68on the frame of the machine. The upper end of this shaft 70 is provided with a head 71 which serves as an abutment for the coil spring 7 2 located within a pocket of the hand piece 69 and pressing downwardly on said hand piece to cause the bottom of the latter to bear with yielding pressure against the upper surface of the gage arm 65, thusholding said arm in its adjusted position. This operating member 69 may be provided with a pocket 1n its bottom for the reception of a gear or pinion 73, the latter being rigidlysecured to the operating member and extending below the latter into the slot 66 of the gage. ()ne' wall of this slot 66 is provided with teeth 74 engaged with the teeth of the gear wheel 7 3 While the other wall is smooth and cotiperates with the ends of said teeth. It will thus'be seen that the operating member not only serves for moving the gage back and forth, but it holds the gage in its adjusted position. A scale 75 on the work support may be utilized for determining the position of the gage.

The operation of the machine may be understood from the foregoing description, but it may be summarized as follows: The check is first placed upon the work support, the gage being adjusted to determine the writing line by means of the hand piece 69 which-holds the gage in its adjusted position; and the spring-pressed rollers 76 being raised by depressing the finger-piece 78 to permit the check to' pass beneath them. The hand piece 28 is shifted to select the matter which is desired to be written on the check and is depressed after each selection of the desired word. With this depression which occurs after the type wheel 17 has been positioned, the locking dog 39 codperates with the gear 'wheel 25 and locks the I latter against rotation, after which the platen 3 coiiperates with the type wheel.

During the adjustment of the type wheel, the gage member or hub 58 is shifted so that the proper shoulder isin position to limit the movement of the three-armed lever of the feeding mechanism prior to the printing after which the lever moves the feed wheels a distance corresponding to the length of the word to be written Among the novel features of this invention is the laten adjustment which permits the serrated platen to properly register with the groovesof the printing type on the printing wheel,- said adjustment not only permitting the raising and lowering and also the lengthwise movement of the platen, but permitting the plane of its serrated face to be tilted in order that it may be made to correspond exactly with the plane of the printing type. I

Anotherfeature of the invention is alocking means which prevents all play in the type wheel after the latter has been ad- .with the work support in such a manner that there is no possibility for the work to pass between the-gage and the work support.
