COMPLETE SPECIFICATION.
Feed Gauge for Printing and Folding Machines.
I, EDWARD L. MEGILL, of 60 Duane Street, in the City of New York, United
States of America, Manufacturer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to feed gauges for registering the position of the sheet
fed to printing presses, and by the proper arrangement or varying of its novel
features it may be made applicable to either cylinder or platen printing presses or
paper folding machines.
My invention consists primarily in an eccentric or cam by which the adjustment
of the sheet is effected, and this eccentric or cam is fixed by a pivot to either the
feed-board, or to a metal base attached to the feed-board, or to the paper attached
on the platen. Said cam or eccentric may bear directly against the sheet in the
feeding of the latter, or the head or flange of a sliding plate adjusted by the cam
or eccentric may be the part to which the sheet is fed.
In the accompanying drawings I represent in perspective views, Figs. 1 and 2,
the invention in its varied forms showing how it may be made applicable to the
different presses, or machines.
The simplest and cheapest form is shown in Fig. 1, which represents a cylindrical
head or stud A mounted eccentrically on a pin-pivot B driven into the feed-
board C on a cylinder printing press or folding machine. This head or stud A is
provided with a milled-knob A' by which it may be revolved with the fingers.
By being mounted eccentrically its revolution will present such portion of its
cylindrical face to the sheet D as shall adjust and support the said sheet to the
position required for printing. It will be noticed that the adjustment of the sheet
thus made is very minute and gradual, and that the same result, although with
another part added, is obtained in the other form illustrated in Fig. 2.
In the Fig. 2 form, the eccentric A is shallow or flat, and is provided with a
lever A secured to the said eccentric by the pivot B and stay-rivet B. This
lever A is used in this form to turn the eccentric instead of the milled-knob A'.
This eccentric is revolvably secured to a fixed metal base C and made permanent
therewith by the said pivot B. There is also secured on the metal base Ca
sliding-plate F, through which the eccentric A passes and by which the said
plate Fis moved in a forward and backward direction. This sliding plate F is
turned down at about a right angle at the forward end to form a head or flange FI
as deep us the base, and it is against this head or flange that the sheet is fed in
this form of the invention.
The sliding plate is kept in a longitudinal line by the guide-ways G. Any
means may be employed, however, to hold this sliding-plate on the base.
The base of this device, as it will be understood from the foregoing description,
may be arranged to be secured to paper on the platen of a press by means of
paste, or by a longitudinal fastening pin underneath; or it may be secured by
screws or bolts to the feed-board of a cylinder printing press or other machines.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed; declare that what I
claim is :-
1. A sheet-registering gauge provided with an eccentric for adjusting the
position of its registering face."
2. A feed gauge having an eccentrically adjustable gauge-head, said head being
provided with an attaching pin or pivot at its base.

page_text: 3. A. feed gauge having a cylindrical or cam-like gauge head, rotatively and
eccentrically mounted and provided with a knurled-head A', substantially as set
forth.
4. In a feed gauge, the combination of the base provided with means for securing
it to the paper on the platen, and the adjustable gauge mounted on said base and
provided with a head or flange.
5. In a feed gauge the combination of a base attachable to the press, of a sliding
gauge-plate and an eccentric or cam for adjusting said gauge-plate, substantially
as herein described.
