I EDWARD L. MEGILL, or BROOKLYN, NEW YORK.

GAGE-PIN F OR PR-lNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 377,949, dated February 14, 1888.

Application filed June 23, 1884.

Serial No. 135,731. (No niodel.)

To all whom it may concern:

Be it known that I, EDWARD L. MEGILL, a

, citizen of the United States, residing at Brooklyn, county of Kings, State of New York, have invented a new and useful Improvement in Gage-Pins for Printing-Presses, of which the following isa specification.

My invention relates to wire gage-pins constructed and operated ashereinafter described.

Figure 1 is a perspective view of the gagepin secured to the platen-paper with the upper layer partly torn away to show the drop curve and the prong between the sheets. Fig. 2 is a plan of the platen and platen-paper-with a set of the gage-pins attached in various ways with relation to the sheet or card placed to them. I

W is the platen-paper, and Y the sheet or card to be printed.

The gage-pin is made of a piece of wire, of any suitable pattern, about two and a half incheslong. Oneend-theprong A-isstraight and about an inch in length. Its point, however, may be bent upward. The opposite end of the wire is bent over upon and across the said prong A in theform of an arm or crook,

B, and the intermediate portion at about a right angle thereto,forming an upright or gage, C. At the intersection of the prong A and gage O is the drop-curve D, which is formed by giving the metal a short bend downward. At the intersection of the upper part of the gage G the crook B is curved forward toproject over the edge of the sheet, but may be bent directly back instead.

The uses of the difierent parts are as follows: The prong A secures the gage-pin to the platen-paper. The crook B keeps the gage G upright when printing, or when lifting the platen-paper for making ready. The gage 0 determines the position of the sheets. The drop-curve D prevents the sheets from catching under the gage and the prong from working out. The crook B also serves to keep the sheets down at the gage and at the lower part holds cards steadily on the platen-paper by a spring pressure, so that they cannot leave the gage after being placed thereto. It also permits the securing of the gage-pin, so that sheets may be placed to the extreme lower edge of the platen-paper.

crook will press on the edge of the sheet or card. At X the prong is inserted so that the point of the crook will lie under the sheet,and

it is in this way that the pins are inserted to the extreme lower edge of gage the sheets at At Z the prong is inserted the platen-paper.

so that the forward part of the crook will simply overlap the edge of the sheet.

In securing the gage-pin, the prong is inserted at the edge of the sheet to be printed and forced home, the drop curve suddenly slipping below the upper layers of the platenpaper through the hole the prong has made. As the prong passes in under the platen-paper, the crook passes over the upper layer. The sheets are fed to the gage from the different sides, as shown. When fed to the front, the sheets set loosely to the gage. When fedto one side,they slide over the point of the crock and set loosely. When fed to the other side, they must be forced under the crook. The curves and proportions may be somewhat varied and different sizes produced. The end of the crook in some cases need not be pointed.

I shall apply the dropcurve improvement D to other gage-pins, including that patented to me May 15, 1883.

In my renewed application refiled February 2, 1887, and bearing even date of issue, Ishow and claim the features of overlapping the prong with the opposite end of the wire and forming of the intermediate portion the upright gage. I therefore do not claim such as,
