IMPROVEMENT IN PAPER-PILERS FOR PRINTI NG-PRESSES.

Specification forming part of Letters Patent No. 217,] 77, dated July 1, 1879; application filed March 12, 1878.

of this specification.

The nature of my invention consists in an attachment to the fly-shaft or fly-head form ing part of the fly-shaft of any printing-press or other machine, where the same may be applied for piling paper straight and even after the fly has carried it over the table, as will be hereinafter more fully set forth.

In order to enable others skilled in the art I to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in whicha Figure l is a perspective view of my invention. Figs. 2 and 3 are detailed views of parts thereof. I

B represents the table on which the paper from aprinting-press or similar machine is de posited. This table is provided on two sides with adjustable guides G (1, against which the paper is to be piled by means of the eveners D D. These eveners are adjustably secured to two rods, to a, which are placed at right angles to each other in suitable guides b I), either on top of or in the table, in such a manner that the eveners will move on top of the table.

The inner ends of the rods to a. are, by links (1 (I, connected with the ends of a bell-crank lever, G, which is pivoted, as shown, to the table. The other end of the rod a is, by a jointed rod, h, connected with the fly-shaft of the printing-press or similar machine, in such a manner that the running of the fly will move the rod a backward and forward in its guides, and, by the connection through the bell-lever Gr, simultaneously therewith move the other rod, to. The eveners D D are thus moved simultaneously inward and outward to pile the paper; i

The guides O G and the side evener, D,n1ay be made solid; but the evener next to the fly is made somewhat in the form of a rake with upwardly-projectin g teeth, so that the arms or fingers of the fly can pass down between them.

I am aware that a receiving-table for printin gpresses has been provided with reciprocating guides operated by a system of togglejoints and springs; but I am not aware that any positive mechanism such as I have shown and described has ever before been known or used.

With my invention I only use a single bellcrank lever and two connecting-links, dispensing with the use of springs and togglejoints.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The eveners D D, placed at right angles to one another and adjustably attached to the rods to a, the bell-crank lever G, the connecting-links d d, and the joint 71-, connecting one of the rods with the fiy-shaft of a printingpress or similar machine, in combination with the two adjustable guides O 0, also placed at right angles to each other, and all arranged in connection with the table B, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I afliX my signature in presence of two witnesses.
