No. 223,243. Patented Jam-6, 1880.
UNITED STATES PATENT OFFICE.
HERRMAN C. PFEIL, OF GAMDEN, NEW JERSEY.
LITHOGRAPHIC-PRINTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 223,243, dated January 6, 1880.
Application led September 18, 1879.
To all whom lt may concern Be it known that I, HERRMAN G. PEEIL, of the city and county ot` Camden, and State of New Jersey, have-invented a new and useful Improvement in Lithographie Presses, which improvement is fully set forth in the following specieation and accompanying drawings, in which- Figure 1 is an end view ot' a portion of a lithographie press embodying my invention. Fi g. 2 is a transverse section thereof on line e' a', Fig. 3. Fig. 3 is a longitudinal section on line g/ y, Fig. 2.
` vSimilar letters of reference indicate correspondin g parts in the several figures.
My invention relates to improvements in lithographie presses more especially designed for printing on glass; and it consists in suspending the pressure-roller in such manner that it yields or conforms to the irregularity of surface of the sheet to be printed, whereby there is a uniformity ot' pressure in printing, and less liability of breaking ofthe glass and stone, and superior work is produced, the construction and operation of the parts being hereinafter fully set forth. 4
Referring to the drawings, A represents the frame ot' a lithographie press, to the top bar of which is fitted a screw, B, extending vertically and having swiveled to its lower end a bisected or split cap, O, which is prevented from displacement from the screw by means ot' the confining-button a at the bottom thereof.
D represents the roller ot the press, whose bearings are on the head E, which is loosely suspended from a spring, F, consisting ot' a curved iiat plate whose ends are pivoted to the beam, and its middle portion is connected to the cap C, the ends of the beam and roller projecting freely into vertical slots a of the side pieces, b, of the frame A.
It will be seen that, owing to the swiveled connection of the screw B and beam E, and the interposed spring F, the roller D is permitted great freedom of motion, and swings in many directions, whereby, when the press is operated, the roller conforms to irregularities of the sheet lto be printed, and there is a uniformity of pressure thereon, the work being regular and superior, and the stone and sheet ot' glass preyented, in a great measure, from breakage.,
The spring F and screw B are readily connected and disconnected by means of the biseeted cap C, the parts of which are easilyl applied to the neck at the bottom of the screw, and then bolted to the spring, or unbolted and displaced, as is evident.
Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is t The bisect'ed cap C, swiveled to the screw B, in combination with the tlat spring F, pivoted to the bcarin gs of the roller D, and con' neet-ed centrally to said cap G, substantially as and for the purpose set forth.
2. The suspended roller D and suspended head E, in combination with the spring F and the screw B, substantially as and for the purpose set forth.
3. The lithographie press having screw B, bisected Acap G, suspended spring F, suspended head E, and suspended roller D, combined and operatin g substantially as and for the purpose set forth.
H. C. PFEIL.
