SPECIFICATION forming part of Letters Patent No. 365.004, dated June 14, 1887.

Application filed October 11, 1886. Scral No. 2l5,F i8. (No model.)

To (LZZ whom it may concern.-

Be it known that I, THOMAS I'IANNIGAN, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and 5 useful Improvements in Devices for Jogging or Evening Sheets of Paper on Fly-Tables of Printing-Presses, of which the following is a specification.

My invention relates to printing-presses, and

more particularly to the devices connected therewith for automatically jogging or evening the sheets of paper as they are successively printed and delivered by the flier on the fly board or table.

It is the object of my invention to simplify the construction of such devices, and at the same time render them more efficient in operation, cheapen the cost of their production, make them less liable to get out of repair,

and secure a material saving of time and power in their operation and manipulation.

My invention consists in providing strips or plates of metal, attached to the flier-frame, of such form and so related to the flier and fly board or table that when the flier shall return to position after having deposited a printed sheet between the gages on the fly-board said strips or plates of metal will come in contact with the forward edge of the sheet of paper,

0 or that edge thereof extending toward the flier, and jog or move the sheet rearward] y into position against the gages.

Having thus indicated the purposes and nature of my invention, I will 110w proceed to 5 describe it, reference being had to the accom panying drawings, and to the letters of reference marked thereon, in which drawings- Figure 1 represents a perspective View of the invention, only so much of the-parts of the 1 0 machine associated with the flier being shown as is necessary to a clear understanding of my improvements. Fig. 2 is a side view of the same, parts being represented as in section.

Similar letters of reference indicate similar parts in both figures.

In carrying out my invention I construct a series of gages, consisting of straight strips of wood or metal a, attached to angular basepieces I), which basepicces are provided with 0 slots adapted to receive therethrough the shank of bolts or screws (1, adapted to be screwed into the fly-table 0, by which means said gages may be moved to and fixed in position on said table against or in close proximity to the edges of sheets of paperf, of varying sizes.

9 represents the flier, and h the flier-frame, of common construction, and adapted, as is well understood by those skilled in the art, to receive the printed paper from the press and deposit it on the fly table or board, Fig. 2 showing in dotted lines the position of the flier at the moment of laying a sheet on the table, while the full lines show it in position to receive a sheet from the press.

1' represents strips of sheet metal secured by 6 one of their ends to the flier-frame, and extending downwardly therefrom below its jour nal-shaft j when the flier is in position to receive a sheet from the press. Said strips iare bent to such form that when the flier is in the position last mentioned their outer or lower portions, 76, will be in substantiallyhorizontal position and rest against the forward edges of the sheets of paperf.

The operation of my invention may be dcscribed as follows After a form is made ready on the press,the gages a a are adjusted on the table 0 in close proximity to the sides of the sheet as it is thrown off by the flier, the rear gages being preferably a little farther from the rear edge of the sheet than are the side gages from the side edges, and the table 0 is moved to such position that when the flier is in the position represented by full lines in the drawings the outer or lower portions, 7t, 8 of the strips 5 will just touch the forward edge of the sheet, the rear edge of which will be substantially in contact with the rear gage or gages, a. In the operation of the flier g the portions k of the strips i will be caused to de- 0 scribe the are of a circle,(indieated by the dotted lines Z Z,) so that when the flier is down to its dotted-line position, Fig. 2, having just' laid a sheet on the fly-table, said strips 1' will be in the position represented by broken lines at m. It is preferred that the flier shall deposit the sheet on the table with its forward. edge a little in advance of the vertical plane of the portions 70 of strips i when the flier is in its full-line position, so that as said flier zoo returns from its dotted to its full line position,

Fig. 2, said portions 70 of strips 27 will come in contact with the forward edge of the sheet tween the gages, the operation of the strips 2',

on the forward edges of the sheet will result in evening it with theother sheets between said gages.

Having thus described my invention, what I claim is- The combination, with the flier, flierlrame, and its journal-shaft, of strips secured to said flier or flier-frame and extending below or beyond the journa1-shaft, the lower or outer 1g ends of said strips being constructed to stand in substantially vertical position when the flier is in raised position, substantially as and for the purpose hereinbefore set forth.

In testimony whereof Ihave signed my name 20 to this specification, in the presence of two subscribing witnesses, this 2d day of October,

THOMAS HANNIGAN.

ARTHUR W. CRossLEY, A. D. HARRISON.
