PRINTERS GAG E-PIN.

SPECIFICATION forming part of Letters Patent No. 458,562, dated September 1, 1891.

Application filed May 14, 1891. Serial No. 392,725. (No model.)

To all whom it may concern:

Be it known that I, J AMES W. EGGLES'ION, a citizen of the United States, residing at Minneapolis,in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Printers Gage-Pins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improvement in printers gage-pins. To this end I employ a device comprising a base securable to the platen and a series of interchangeable retaining-pieces differing in width of face or retaining-surface securable to the base-piece.

The device is illustrated in the accompanying drawings, wherein like letters refer to like parts throughout the several views.

Figure 1 is aside elevation of the device in working position. Figs. 2 and 3 are respectively a plan and rear elevation of the platen of the printing-press with two of the gagepins in position thereon. Fig. at is a plan view of the basepiece of the gage secured to a portion of the platen-covering, and Fig. 5 is a sectional elevation of the same on the line X X. Fig. 6 shows the series of interchange able parts. Fig. 7 is a rear View of a yokelike strip for more permanently securing the base of the gage-pin to the platen-covering.

A 13 O are respectively the frame, the impression-bed, and the platen of a hand printing-press.

D is a covering, of paper or felt, secured on the upper face of the platen, and D represents an envelope or other blank material held in position by the gage-pins.

E F are the gage-pins, of which E is the base, and F is one of the interchangeable re taining-pieces. This base-piece E is of T shape, having its head provided with an elongated slit 6, extending lengthwise thereof. To the under side, at either extremity of this head, are secured brad-like pins e, extending slightly downward,then bent upon themselves rearward to permit their insertion below the surface of the platen-covering, as best shown in Figs. 4 and 5. The interchageable parts F are angular pieces of thin metal, the depending portions f of which fit the slit (2 of the base'piece E, where they will be held by friction. One or another of the interchange able pieces is employed, according to the re quirements of the work.

To more rigidly secure the base of the gagepin to the platen, I may employ a strip G, of heavy paper or other suitable materiahwhrch is looped over the stem of the base-piece, as shown in Figs. 2, 3, and 7. It may be possible to dispense with the brads e and rely on the loop A alone to secure the base to the platen.

What I claim, and desire to secure by Letters Patent of the United States, is .as follows:

1. In a gage-pin, the combination, with a base-piece attachable to the face of the platen, of a series of interchangeable retaining-pieces securable to the base-piece, having different widths of face or retaining-surface.

2. In a gage-pin, the combination, with a slitted base-piece attachable to the face of the platen,of a series of interchangeable retaining-pieoes having different widths of face or retaining-surface provided with a downturned flange fitting the slit in the base-piece for se curing the same therein.
