1,138,711. Specification of Letters Patent.

To all whom it may concern: Referring to the drawings, Figs. 1, 2, 3, 4 Bev it known that I, ERASTUS WoooWARD, and C represents the supporting frame of of Somerville, in the county of Middlesex the machine described in my application and State of Massachusetts, have invented Serial Number 527,633 which frame carries certain new and useful Improvements in the rock shaft D mounted in the bearing C Inking Devices for Printing and Marking in the upper part thereof, said shaft having Machines, of which the following is a specisecured to its outer end by set screws D the fication. yoke arm D, which carriesmounted on its My invention relates to improvements in free end the inkin mechanism E. inking devices for stamping and marking The rock shaft is mounted in the bearm-achines, and its object is to provide autoing C and carries the lever or type arm G matic mechanism for normally covering and secured'thereto by the set screw G The Y protecting the ink to exclude the dirt and type head J is secured by clamp screw J 2 to dust and prevent evaporation when the dethe outer end of type arm G. The rock vice is not in use, and to automatically uncover and operate the device when it is necessary to ink the type.

The important feature of this device is the provision of mechanism for automatically upon which the articles are placed to receive shifting the position of the ink roll at each inking operation to expose and contact a different portion of the ink roll withthe type at each inking operation.

shafts D and G are thrown into cooperation with and drawn by a suitable clutch at each operationas described in the above named application.

H represents the work supporting table the impression of the type head J 7 The type head J (see Figs. 1 and 4) is of the usual construction, consisting of the ring Another feature of this device is the utitype disks J rotatably mounted on a central lization of an absorbent pad which carries shaft J 4 which is journaled in the type head the ink and which contacts with and wipes J The knob J 5 is secured to the outer prothe ink roll, thereby feeding the ink evenly jecting end of shaft J 4 and is for the purto the roll and preventing an excess accumupose of manually adjusting and frictionally lation of ink thereon. turning whichever of the said type disks In the accompanying drawings which that may be released by suitable pawls J illustrate a construction embodying my inpivoted on the shaft J 6 so that the required vention Figure'l is a side elevation of the figures or characters located on the periphdevice operating in conjunction with the cry of the disks J 8 may be removed into marking machine shown and described in alinement for making an impression on the my application Serial Number 527,633, the 'articles to be marked. p parts being shown in normal or operating The inking mechanism E (see Figs. 6, 7

' position. Figs. 2 and 3 are similar views, 8 and 9) comprises the casing E which carshowing the consecutive positions and operaries a hollow supporting stem E mounted tions of the inking mechanism prior to each within the clamp D to the lower end of the impression of the type head. Fig. 4 is a yoke arm D. The screw D is adapted to front elevation of Fig. 1. Fig. 5 is a similar clamp the casing E in position on said yoke view to Fig. 4 with the type head and an arm D (see Fig. 1). inking device removed with parts broken In the casing E is a shaft E which caraway to more clearly illustrate the mecharies the ink-roll E". Mounted inside and nism for connecting the inking device with at the rear of the casing E is an absorbent the machine. Fig. 6 is a top plan view of composition E preferably felt, which abthe inking device with the'cover and autosorbs and retains the ink. A felt wiper E matic shutter removed. Fig. 7 is a vertical is fastened at one end upon a pin E and left cross section through the center of the defree at its opposite end. This wiper is vice and Figs. 8 and 9 are respectively the located between the composition E and the covering and automatic shutter for covering roll E, being in contact with and extending the same. I around the greater portion ofthe periphery Like letters of reference refer to like parts of said roll E. This serves to prevent the throughout the several .views. composition E from getting beneath and clogging the roll E when the same turns,

and also serves to distribute the ink evenly upon the outer periphery of the roll.

E is a cover having an aperture therein E to give access to the ink roll E", said cover being secured to the upper part of the casing E by means of screws E. I

To prevent evaporation of the ink when. the type is not in contact with the ink roll E an automatic shutter E is provided which is reciprocally mounted upon the top of the cover E and normally closes the aperture E. This shutter E carries stem E extending through the hollow stem E the portion of said stem E projecting through the hollow stem E carrying a notch E which engages with the spring latch E (see Figs. 1 and 5). This latch E is pivoted at E in a slot in the lower end of the hanger E the upper end of which hanger is loosely mounted on the hub E in the upper end of the yoke arm D. The spring E secured to'the lower end of the hanger E acts against the extension E of the spring latch E to hold said latch in position within the notch E.

E and E are stops carried by hanger E on respectively opposite sides of the rib E on the main frame C.

The operation of the shutter is shown in Figs. 1, 2 and 3, Figs/2 and 3 showing-the shutter withdrawn while the type is being inked and Fig. 1 showing the shutter closed, entirely covering the ink roll E when the type is not being inked. On one end of the shutter E is a rack E which meshes with a pinion E loosely mounted over one end of the shaft E E is a sprin pawl secured to the pinion E by a screw said pawl adapted to engage with a ratchet wheel E secured to the extreme outer end of the shaft E .When the shutter E is opened the rack E moves the pinion E upon the shaft E causing the pawl E to engage one of the teeth of the ratchet wheel E causing the ink roll E to be turned a portion of a revolution, which moves into position for contacting with the type a portion of the ink roll which had previously been in engagement with the wiper E When the shutter is closed the pinion E is operated in the reverse direction while the pawl E nearly slides over the teeth of the ratchet wheel E.

The operation is as follows: With the parts in a normal or-non-operating position as shown in full lines in Fig. 1, the operator desiring to print or stamp the articles places the same on the work supportin table H, and presses the foot pedal which throws into action with the driving power the clutch which has been fully described in my application hereinbeforereferred to, which action of the clutch operates to move the rock shaft D, moving the yoke arm D and inking mechanism E outward and upward (see Fig. 2) until the stop E has engaged the rib E which stops any further movement of the hanger E causing the shutter E to be withdrawn and exposing the ink roll E which in the meantime has been moved as hereinbefore described, exposing a freshly inked portion of the ink roll E. A further movement of the yoke arm I) causes the roll to contact with one edge of the type on type head J. In the meantime the rock shaft G is operated to move the type head J upward together with the inking mechanism E, continued relative movement of the type head J and the inking mechanism E causing the ink roll E to roll along the face of the type while the rack E continues to operate the pinion E and roll E until the type head J drawsaway from the ink roll E as shown in Fig. 3. The type head J now remains momentarily stationary while the inking mechanism E is operated by the rock shaft D to draw away from the'type head and return to its normal position as shown in Fig. 1. In the meantime after the inking mechanism E has moved out of the way of the type head J the rock shaft G causes the type head J to be moved downward to the dotted line position shown in Fig. 1, marking the article located on the table H, whilethe continued movement of the machine causes the type head J to be moved upward to its normal position as shown in full lines Fig. 1. Upon the return movement of the inking mechanism E as described the stop E engages the rib E stopping the movement of the hanger E thereby closing the shutter E. The machine is now at rest in its normal position ,with the inking mechanism E covered,

which prevents any evaporation of the ink.

I do not limit myself to a step movement of the ink roll E to consecutively expose a freshly inked portion of the same for inking the type, as the roll E may be oscillated sufliciently to freshly ink the portion of the roll which engages the type at each operation.

Having thus described my invention and set forth a construction embodying the same what I claim as new and desire to secure by Letters Patent of the United States is:
