In the embodiment of the invention herein illustrated, there is provided a frame comprising a lower or base section 1 and an upper or top section 2 secured to the lower or base section by screws 3. The lower or base section is spaced at its front at 4 from the upper section to provide a slot through which the work may be passed and the top lOO . a support for the work.

of the base section on one side of this slot is provided with a plate 5 which serves as The under side of the upper section 2 above the slot has a cover plate 6 which protects the upper face of the work against the action of ink or grease from the parts in the upper section, this plate 6 being held in place by screws 7 A platen 8 is mounted in the lower section, while the printing mechanism is mounted in the upper section. In this embodiment of the invention, the platen is in the form of a roller secured to a shaft 9 and having its periphery operating through a slot 10' in the work support 5 so that the printing mechanism may cooperate with the platen. The shaft 9 may be supported in any suitable manner. In this instance, it

is journalled at opposite ends in two arms 11 which are pivotally supported at 12 on the base 1 and have screws 13 at their outer ends anchored in lugs 14 on the base 1. These arms also carry screws 15 which have abutments against said lugs 14;. By this arrangement itis possible to adjust the arms 12 with the shaft 9 carried thereby so that the roller 8 may be moved toward and from the printing mechanism for the purpose of increasing or decreasing the pressure on the work.

The printing mechanism, in this embodiment, is in the form of a rotary carrier 16 secured to a shaft 17 by a screw 18, the shaft being journalled at 19 in the upper section'2 of the casing, its rear end extending through the casing and having a handle 20 connected thereto through which the shaft and the rotary carrier of the printing mechanism may be turned. The rotary carrier has the printing elements movably mounted thereon and adapted to be projected to printing positions for engagement with the platen 6. These printing elements are, in this instance, in the form of blocks 21 arranged in radial grooves 22 formed in the rotary carrier 16. To the end that these blocks may be individually projected from the carrier, the carrier has the bottom surface 23 of each groove inclined with relation to the axis of turning of the carrier to form a guide. and the bottom surface of each printing element is also inclined to cooperate with the inclined bottom of the groove, thus providing two cam surfaces which, when the printing member is moved longitudinally of the axis of the rotary carrier, causes the printing member to move also radially ofthe carrier so that the print ing character 24 lies in a position to cooperate with the platen 8 when the rotary carrier is turned to bring the character to theplaten. At this time the character will operate through a slot 25 formed in the plate 6. lVith the object in view of effecting the movement of the printing element longitudinally of the rotary carrier andalso radially thereof, each printing element is Provided with a key 26, this key having its stem 27 connected to the printing element and the keys projecting from the front of the upper casing section 2 and lying in an annular series, suitable indicating matter being provided on the keys to correspond with the printing characters 24-. l/Vith the purpose in view of confining the printing elements 27 inithe grooves,a cap plate 28 may be provided on the front of the rotary carrier 6, this cap plate having a flared flange 29 which projects into notches 30 in theprinting elements to cooperate with one wall of said notch. The outer ends of the printing elements beyond the cap plate are covered by a. ring 80 which'has radial slots 31 through which the stems 27 of the casing 26 extend.

With the object in view of locking the printing elements in printing position on the rotary carrier 16, locking means is provided, in this instance, in the form of a plate 31 secured by screws 32 to the rear face of the rotary carrier 16, the periphery of this plate being engaged by inclined or cam portions 33 one on each printing element each cam portion cooperating with the plate 32 when the printing element is moved by its key 26 and causing the printing element to move slightly away from the bottom wall of the groove in the rotary car-' rier until the'end of the cam portion 33 isreached. At this time the shoulder 3 1 formed at the end of the cam portion 33 will engage the rear face of the plate 31 and lock the printing element in its printing position. In order that the printing ele ment may be held in engagement with the plate each printing element has a helical spring 35 connected at one end to a projection 36 on the rear end of the printing ele ment and its inner end to a screw 87 on the rear face of the printing element, this spring also serving to return the printing element to non-printing position when the printing element is released by the locking means To facilitate the movement of the printing member in the groove under the action of the cam 83, the forward end of the printing member may be bevelled at38. WVith the end in view of insuring the engagement of the shoulder 34 with the plate 31 in order that proper alignment of the printing surfaces may be obtained, there may be provided an aligning device comprising, in this instance. a plate 49 secured at 50 and extending downwardly from its point of attachment to the path of travel of the pro- 'ections 86, this plate being so deflected or cut that the project-ions may freely ride onto its surface to be engaged by the latter in order to move the printing element lougitudinally or in the direction of the axis of frame are pivoted at '79.

rupturing roller the shatt 9 will he s d and wiil he turned through the energy red in the spring; .5: acting on the slip-olf med by the members and 57.

'ahle means may be employed for holding the work against accidental displ cement while the printing elements are out of cooperation therewith. In this inance, a work holding device 62 cooperates h the work: support ii and is carried by an, arm (12% which extends through. a slot 64: in the cash from a. rock shatt 65 jourin s d easing. this rock shatt having n a ll 0 f. an opera ting; arm 6 extending laterally therefrom to the exterior of the casing ihroua h a slot 67, the outer end of the arm havinga finger piece (38 which, when dopres ed turns the rock shatt to elevate the work clamp (32, a coil. spring 69 surrounding the rock shatt and. tending; to return the work clamp (32 in cooperation *ith the work support v The printing; characters be inked throunjh any suitable means. In this inec. the wall of the casing 2 is provided wit-. an opening; 70 on opposite sides of which thu s 71 pro ec't. Fitting over these flanges is a cover plate 72 whose lower edge 7 3 looks with a groove or recess T l in the casing and whose upper edge is held by a latch 75 pivoted on a pin This cover plate carries a post 77 to which the arms 78 of an ink roller carrying," Rollers 80 are iournalled in this tramo. one of said rollers cooperating with the printing faces, while the other oi said rollers acting to supply ink to said roller 80. it. stop Sl. limits the movement of the rollers toward the carrier 1.6 under the action of a spring 82.

The operation of the invention will be understood vfrom the foregoing description, but it may be summarized. as follows:

The work X placed upon. the work support 5 under the work clamp 62. One or more ot the keys 26 are engaged by a. finger of the user to press the printing elements inwardly so to cause them to move both longitudinally and radially with reference to the shaft 17 through the cooperation of the inclined surfaces on the printing; elements with the surfaces 2? until the shoulders 341; engage with the plate 31, as shown in Fig: 1.3. In this position, the printing: surface 24; and the rupturing sin-taco do will.

he in positions to engage respectively the platen 8 and the rupturing)- surface 46 when the rotary carrier 16 is turned. Ordinarily only one of the printing elements 21 is moved for each turningmovement of the rotary carrier, but it the matter to be written. occurs in the same succession in the rotary carrier, then more than one of the printing elements may be moved to printing position, as for instance, when $48.00 is to be written, the printing elements carrying the sign 4: and 8 are moved to printing position before the rotary carrier is turned. Thereafter the rotary carrier is turned and the characters will be successively printed on the work through the one rotation of the carrier. Of course, if these characters are reversed as 5584;.00, then this operation cannot he "followed and only the sign with the 8 can be printed together, a separate operation being required to print the 4. By this arrangement it the characters occur on the printed matter in the same order on the machine, it is possible to set the machine, by moving the resetting device 39 to an inoperative position as shown in Fig. 13, so as to print a number of checks of a like amount without adjusting the printing elements after each printing; operation. This is especially desirable where a large number of checks for a like amount are to be issued, as in paying off a large group oi? workmen getting the same wage. The resetting device when in operative position as shown in Fig. 12, will cooperate with the projections 36 andpermit the springs 35 to return. the

printing elements to normal printingposi tions, this being effected immediately after the printing has been completed by the printing element. The proper alignment oi the characters is insured through the aligning device 4.9 which cooperates with. the prothe shaft on which the rupturing device 46 is mounted, engagement of: the work with the rupturing device being sufficient to effect this return.

From the foregoing it will be seen that there has been provided a printing; machine inwhich the printing eloment-s are arranged on a rotary carrier in such a manner that they may be moved radially with reference to the turning axis of the carrier to printing position on such carrier. This radial movement is effected through a simple means which provides a firm support tor the p rinting elements during theprinting action. A. simple means is also provided for locking the printing elements in printing position. The printing elements are autoimitically released. from the locking means after the printing operation and the releasing or resetting means is movable to an inoperative position so that a repetition of the printing operation may take place with the same character or characters. Means is also provided which insures the proper aligningof the printing characters, and a means is employed which automatically shifts the Work in a direction opposite to the feeding direction so that a proper spacing; between the characters on the printing matter may be obtained. This return movement of the Work is accomplished through a spring means which has a slip connection with. the rupturing means below the work so that the rupturing means may complete its ruptur ing action and will. when freed by the rupturing means on the ninting element re turn a slight distance under the action of the spring to produce a slight return move ment of the work.
