Description
CALVERT B. OOTTRELL, OF WESTERLY, RHODE ISLAND.
IMPROVEMENT IN PRINTING-PRESSES.
Specification forming part of Letters Patent No. 140,813, dated July 15, 1873; application filed June 21, 1873. 1
To all whom it may concern:
Be it known that I, CALVERT B. OOTTRELL, of Westerly, in the county of Washingtonand State of Ithode Island, have-invented a new and useful Improvement in Printing-Presses, of which the following is a specification:
Figure 1 is a transverse section of so much of a printing-press as is necessary to illustrate my invention, the section being taken on the line 3 y of Fig. 2; and Fig. 2 is a longitudinal sectional elevation taken on the line y y of Fig. 1.
Similar letters of reference indicate correspondin g parts.
The'invention consists in gearing the sliders with the frame of the press, also with the reciprocating type-bed to maintain the proper relation of said sliders to the table at all times, and prevent the overrunning of one by the other, which now happens in consequence of the irregular action of the bed on the'sliders, caused by the pressure of the cylinder on the bed when going one way and the freedom from pressure when going the other way. In consequence of this action the sliders sometimes work so far beyond their true position one way that they run against the end of their race-ways and stop beforethe bed comes to the end of its movement, and thus make confusion and necessitate the readjustin g of them. There-- fore, I propose to gear the sliders with the frame and the table, so that while they will be free to perform their legitimate functions they will be controlled positively, so that they cannot advance or retrograde relatively to the bed; and to this end I propose, as one example of apparatus that may be employed for this purpose, a revolving shaft, A, mounted in bearings on the reciprocating'bed B, so as to be carried forward and back with it, and gearing by small pinions O with the sliders I), which have a toothed rack for the purpose, also gearing with a toothed rack, E, by a wheel, F, twice the size of the pinions O, the said rack being stationary on the frame of the press.
' As the bed rolls on the friction-rollers G, in the sliders D, and the rollers run on the rails H, the bed of course runs twice as fast as the sliders; hence it is that the pinions gearing with them are half the size, or have half the number of teeth that the wheel gearing with the stationary rack has.
I do not limit myself to this arrangement of gearing, as the same result can be obtained by other means.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The sliders, for the reciprocating bed of a printing-press, geared with the bed and the press frame in such manner that they will be prevented from overrunning or retrograding relatively to the bed while being free to perform their special function, substantially as specified.
