IMPROVEMENT IN COPYING-PRESS BEDS.
Specification forming part of Letters Patent No. 130,320, dated August 6, 1872.
Specification` describing certain Improvements in Copying-Presses, by WALTER SHRI- VER, of New York city, New York.
The undersigned has .invented an improved method of bracing or strengthening the bedplates of copying-presses, and the following is a description thereof, reference being had to the accompanying drawing.
The usual method of strengthening the bedplate of a copying-press is shown at Fig. 2, and is by means of longitudinally-placed bracing-ribs of wedge-shaped section, as shown at O O 0 O. In my improved lmethod (see Fig. 1) I use ribs S S S S, consisting of a combination of web and iiange, in which the disposition of material is such that the resistance to strain on the bed-plate when the press is in use is withstood by the ange at foot of the web of the rib, as shown in drawing, reversing the case of the wedge-shaped rib usually employed, shown in Fig. 2, in which the greatest strain is on the wedge-pointed edge of the rib O, where there is the least inateral to resist the strain.
What- I claim as new, and Wish to secure by Letters Patent, is-
The improved method of bracing orstren gthening copying-press bed-plates, in the manner substantially as set forth.
WALTER SHRIVER.
