PRINTING-MACHINE.

To all whom it may concern:

Be it known that I, HORACE L. Donen, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Printing-Machines, of which the following is a specification.

This invention relates to printing machines and has for its object the provision of a machine of simple and durable construction which is especially adapted for printing tags, but may be adjusted to print various other matter with equal facility.

The particular object of the invention is the provision of an inking mechanism, which includes a pivoted element mounted for contact with the type bed and having means for automatically moving the said element out of the path of the bed to permit the latter to make an impression.

Other objects and advantages of themvention will appear as the following description is read in connection with the accompanying drawings.

In the drawings Figure 1 is a top plan view of a printing machine embodying the present invention:

Fig. 2 is a vertical longitudinal sectional view with the machine in inking position;

Fig. 3 is a similar view with the machine in printing position.

Referring to the drawings in detail, wherein like characters of reference denote corresponding parts throughout the several views,

The machine illustrated in the present application is of the miniature type and may be either operated by 'hand or suitable power. It comprises a base 10, from each side of which rises plates or standards 11, which support bearings for various parts of the operating mechanism. The base 10 supports a'feeding platform 11 over which the stock 12 is adapted to travel.

Also mounted upon the base 10 is a platen 13, which is supported on standards 14: mounted in threaded openings 15 in the base and carrying adjusting nuts 16, so that the height of the platen maybe regulated to provide for the printing of stock of different thicknesses, adapting the machine for the printing of tags for which it is especially designed or for printing other mat ter. Mounted in standards 17 secured to the base 10 is a removable guide plate 18, the

end of which is downwardly curved and rests upon the said base, while a pivotally mounted plate 19 is secured within the standards 17 so as to bear upon the upper I surface of the stock to hold it in proper position for printing.

Mounted in the side plates or standards 11 in suitable bearings 20, is a shaft 21, which may be operated by hand, or through the medium of a motor 22 and gearing 23. The shaft 21 has mounted thereon an eccentric 24, the band 25 of which is connected through the medium of an arm 26 with a lever 27, the latter being pivotally mounted as at 28. The connection between the arm 26 and the lever 27 is made through a screw 29 adjustable in a slot 30 in said lever. Also adjustably mounted in the slot 30 is a pin 31, which is carried by one end of a connecting rod 32, the opposite end of this rod being connected to a lever 33, which is pivoted upon a shaft 34 mounted in bearings in standards 35. The lever 34 carries a spring actuated dog 36, which engages the teeth in a ratchet wheel 37, so that move ment of the eccentric 3-1 will operate the lever 38 to intermittently rotate the ratchet wheel 37 and with it the shaft 34. Mounted upon the shaft 34: are spaced feed wheels 38, which together with rollers 89 act to feed the stock 12 over the platen 18 during the operation of the machine. The pin 31 is adjustably mounted in the slot 30 through the medium; of an adjusting screw 39' and-a nut 40. By adjusting the screw 29 and pin 31 in the slot 30, the throw of the lever 83 may be regulated so as to provide for a greater or less rotation of the shaft 3 1 and the consequent regulation of the degree of feed of the stock 12.

Mounted upon the base 10, are standards 44, which are slotted as shown at for the reception of the ends of a cross bar 16. This bar carries the chase 47 which contains printing type 18, the latter being mounted for movement directly above the platen 13. The chase a7 is movable through the medium of eccentrics d9, which carry bands 50 and which are connected through the medium of arms 51 with the ends of bars 46, the cocentrics 49 being mounted upon the shaft 21, so that when the latter is revolved the type will be moved into and out of engagement with the stock passing through the platen. The eccentrics are so timed that an impression upon the stock will be made during a pause of the intermittent movement of the feed mechanism.

Pivotally mounted in supports 52 secured to the base adjacent the standards H, is an arm 58, one end of which is extended at substantially a right angle and carries an inking pad 54. The opposite end of this arm is provided with curved surfaces 55 for engagement with a cam 56 mounted upon the shaft 21, the end of the arm '53 being held in engagement with the cam through the medium of a spring 57. This cam is sotimed that when the chase a7 is raised through the medium of the eccentrics 49, the pad 54: will be moved upward into contact with the type 48 so as to ink the type and will be moved from the path of the type through the medium of the spring 57 as the chase descends.

In order to hold the stock 12 in proper alinement as it is fed through the machine and to provide guiding means for stock of different widths, there is mounted upon brackets 70 at each side of the machine, guides '71, these guides are in the form of vertically disposed plates provided with laterally and outwardly extending slotted arms 72, which are engaged by adjusting screws 73, so as to permit of lateral adjustment of the guides.

It is believed that when the foregoing description is read in connection with the accompanying drawings, the construction, operation and advantages of the invention will be apparent and that a more'extended description is unnecessary.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention, what is claimed is 1. The combination with a printing machine provided with a Vertically movable bed, of an inking element mounted for pivotal movement and adapted to contact with the type in the bed, cam operated means for moving the inking element in contact with the type when the bed is in raised position and a springhaving one end secured to the inking element and its opposite end movable with the bed to tension the spring and hold the inking element in contact with the cam. v

2. The combination with a printing machine provided with a vertically movable bed, of an inking element mounted for pivotal movement and comprising a pivotally mounted cam engaged arm, an arm extending substantially at right angles to the cam engaged arm, an inking pad secured to the upper surface of the right angular arm and adapted to contact with the type in the bed, cam operated means for moving the inking element in contact with the type when the bed is in raised position and a spring having one end secured to the pivotally mounted arm for the inking element and its opposite end movable with the bed to tension the spring and hold the inking element in contact with the cam.

The combination with a printing machine provided with a vertically movable bed, of an inking element mounted for pivotal movement and adapted to. contact with the type of the bed, cam operated means for moving the inking element in contact with the type when the bed is in raised position and means connecting the inking element and bed for holding the, former in contact with the cam.

4. The combination with a printing machine provided with a vertically movable bed, of an inlsing element mounted for pivotal movement and adapted to contact with the type in the bed, cam operated means for moving the inking element in contact with the type when the bed is in raised position and means controlled by the movement of the bed for holding the inking element in contact with the cam.

In testimony whereof I afiix my signature.

HORACE L. DODGE.
