IMPROVEMENT IN PRINTINGWPRESSES.

The Schedule referred to in these LettersA Patent and making part of the same.

To allwhom it may concern:

Be it known that I, WILLIAM T. Monenns, of Youngsvillain the county of Sullivan, and State ot' New York, have invented a new and useful Improvement in Printing-Press; and I do hereby declare'that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to new and useful improvemeut-s in printing-presses, of the class designed for printing cards, hand-bills, Sto., whereby they are greatly simplitied and reduced in expense; and consists in the construct-ion, combination, and arrangement hereinafter described.

Figure 1 represents a vertical section of the press, through the line a: a: of fig. 2, showing the general arrangement of parts and the method of operation.

Figure 2 is a top or plan view.

Similar letters of refe-rence indicate corresponding parts.

A is the frame, by which the operating-parts of the machine are supported. The frame consists of two upright sides, which rest upon the door, between which the bed' is securely. fastened and the rollers revolve.

B is the bed.

Gis the platen. A

D represents the driving-shaft, to `,one end of which the ily-wheel E is attached.

The shaft D may be revolved by any convenient power.- In this example of my invention, the press is driven by foot-power, applied to a treadle, F, which is connected with a crank' in the shaft, as seen in the drawing at g, by means ofthe connecting-rod H.

Immediately above the shaft D is another shaft, I, with a gear-wheel, J, on each end. This shaft I is revolved by pinion k, one or more, on the drivingshaft D.

The platen-frame is pivoted to the frame A, at the point 'L on each side, and the platen is oscillated and brought up to the bed for giving the impression by means of the rods MM, which are connected to the platen-frame by the pivot-pins, by which they platen is secured to the frame. The other ends of the rods M M are connected with the wheels J J by wrist-pins n n.'

The ends which are connected with the platenframe are slotted, and the pivots are contained in boxes, which are adjustable in the slots by means of the set-screws 'i i. By this adjustment, the platen is kept parallel with the bed, or may be made to give a. stronger pressure and heavier impression at one side than the other.

There are also set-screws in the bar o of the platenframe, which` act against the lowcr'portion of the platen, by which that portion of the platen may be adjusted with regard to the bed. @ne of 'these setscrews is seen at p.

It represents the type-roller.

S and T are ink-distributing rollers.

The type-roller It is given a circular movement and traverses the bed B from a point belev.y its centre, or as low as may be desired, upward, vtill it comes in contact with the roller S, from where it receives its ink.

Ink may be placed upon the curved surface U, over which the ink-roller passes, and from which it receives its supply of ink; but I prefer to take ink from the roller S, which may revolve in a fountain.

The type-roller It is given its trato ing-motion by means of the arms V V, which are attached to the end of a cross-shaft, W", seen in dotted lines in fig. 2. This shaft is arock-shaft, and reccm its motion from an arm, X, which is attached to is cross-bar O of the platen-trame, and connected with the arm Y, ou the shaft W, by the rod Z. This ich. or type-roller It revolves on pivots in its ends, in slots in`the arms V, as seen in iig. 1, and is held in position, and is allowed an irregular' circular motion over the bed and curved surface U, by means of spiral springscc, as seen in fig. 2.

The roller S is revolved from one of the wheels J, which engages with a stud-pinion,

d is a gear-wheel, on the end oft-h slr-,aft of the roller S, which meshes into the pinion c.

The stud-pinion is used for the purpose cf throwing the roller-wheel d nearer the frame, so that the arm V will pass over it.

The roller T is revolved by friction with S, with which it is brought in contact. Both rollers are dropped loosely on to their bearings in the top of thel frame, from which eithcrmay be removed, by simply raising them.

The roller T is given a longitudinal motion, in addition to its rotary motion, by means of a perpetua-l screw on one end of its shaft, which works in a stationary slotted arm, seen at c' fig. 2. This motion is given for the purpose of more evenly distributing and spreading the ink on the roller S.

'By this arrangementA and combination of parts, a simple, cheap, and effective printing-press is produced, one 'not likely to get out of order, and admirably adapted to the purposes for which it is intended.

Having thus described my invention.

l claim as new, and desire to secure by Letters Patent-.-

Operating the type-roller It from the platen-frame, by means of the arms X and Y, red 56, and arms V, substantially as described.

NV. T. MORGANS.
