Description
JAMES `M. .nowusomor BROOKLYN, NEW ironic` imnovnmsnfr IN vPRIN:rnrG-Pnessns rlfheSehedule referred to in these Letters Patent and making part of the same.
I, JAMES BROWNSON, of Brooklyn, in the'county f Kings, and State of N ew, York, have invented certain Improvements in Printing-Presses, of which the following is a specification.y
Nature and Objects lof the Invention.
My invent-ion relatesl to printing-presses, and` con--A sists in the employment ofmechanism for automatically holding the sheets, so as to insure their proper delivery to the gripers on the impression-cylinder.
Description of the Accompanying Drawings.
"Figure 1 Iis a side elevation of a cylinder press with my improvement attaehed thereto.
Figure 2`is a front elevation of the same.
` General Description.
A represents a bar, placed above the feed-table of a press, immediately over the impression-eylinder, it heilig held in position by the supports B B, secured to the side frames of the press.
'lo thisl bar 'are secured the bearings-D D, in which 4the weights a a slide.
rllhese weights are so operated, that when the guides.- or stops by which the sheet is registered are \vith-' drawn, to allow" the nippers uponl the impression-,cylinder to seize the sheet, thcy.will drop upon and hold the paper in position until the nppers have taken it.
The weights are `operated by the arms bbron the shaft E, to `which the former are connected by the links c, and the shaft E is actuated by the arm d, secured to it, and the cam F on the impression-cylinder shaft, upon which the roller e, on the end of the arm d, rests. Y
This cam is so shaped and adjusted on the shaft, i
that at the proper intervals the weights a are dropped upon the paper, or raised therefrom, as may be required. i
By the' employment of this mechanism, the sheet is held in position, Vand prevented 'from being moved, by the vibration ot' the press or other means, at the moment when the register-stops on the end of the feed-table have'ben withdrawn'to permit the nippers to seize .the paper, so that a perfect register ot' the sheet maybe always obtained.
The weights :ire eonneetedtto the arms b, independ- -entlygfby the `flexible links, in order to enable the .weig'htsto accommodate themselves toany inequality that may occur iu the level of the feed-table.
C'lal'ni; I claim automatically holding and releasing the sheets, so as to insure their properpdelivery to the nippers as they are fed to the press, substantially as de scribed and specified. v
` JAMES M. BROWNSON.
