y UNITED STATES OULLEN WHIPPLE, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO JOHN PATENT OFFICE.

W. FIELDER, OF BOSTON, MASSACHUSETTS.

HAND PRINTING-PRESS.

Specilication forming part of Letters Patent- No. 45,000, dated November S, 1864.

To @ZZ wwwt it may concern:

Be it known that I, GULLEN WHIPPLE, of the city ot' Providence, in the county of Providence, in the State ot' Rhode Island, have made certain Improvements in Hand Printing-- Iresses, and in order that others may understand the nature and use of my invention, I give the following description, illustrated by the accompanying drawings, and referred to in this schedule by the iigures and letters marked thereon.

In the drawings, Figure l is a side view of the press.

A A represent the bed upon which the working parts are mounted B, the printinglever, jointed to the bed at one end and carrying the typeplate at the other; C, a secondary lever for operating the sliding bed; D, the sliding bed for receiving the impression 5 E, a connecting-rod attached to the sliding bed and the arm of the secondary lever; F, a spiral spring, one end of' which is attached to the printing-lever and the other to the connecting-rod.` Its office is to throw the sliding bed forward when the levers are up. Gis the type-block afiixed to the printing-lever by (lovetail and screws; H H, handles attached to the two levers for pressing them down; J, the ways in which the sliding bed moves.

Fig. 2 is a top view of the bed-piece, showing its shape and the sliding bed and connecting-rod, the sliding bed being withdrawn to show the ink-pad beneath.

I is the ink-pad, made ot' felt or any other suitable fibrous or elastic materials.

Parts shown and not referred to in this description are marked with the same letters as the other figures.

Fig. 3 is a side longitudinal section of the press, only sucli parts being referred toas are not shown in the other figures.

I is the ink-pad lying beneath the sliding bed; K,a stift' spiral coil around the jointpin of the printing-lever B, to throw it up after the impression is given. L is a recess cast in the printing-lever, which receives the spiral face ol' the type presses upon it and receives the supply of ink. Place the paper upon the sliding bed as soon as the pressure is removed and then press downward only the printinglever, and the impression is given. Thus alternately pressing down both levers at one time and only the printing-lever at the other,

the process of inking and printing is rapidly performed.

I do not confine myself to the exact forms shown for the details. of the working parts. For instance, the connecting-rod may be attached to the sliding bed by means of a hook instead of a pin, land the upper or secondary lever may be provided with a roll just beneath the handle, where it strikes the printing-lever, to reduce the friction, and straight springs may be substituted for spiral to throw the levers up, but these changes do not atfect the principle.

l am aware that hand-presses with the typeplate affixed to the under side ot' a jointed lever have been made of various forms; therefore I do not claim this; but

What I do claim as novel and useful is The ink-pad beneath the sliding' bed, the sliding bed, the secondary lever, and their connections, in combination with the printinglever, all made and operating substantially as set forth, or their mechanical equivalents.

Witnesses: CULLEN WHIPPLE.
