JOHN GASKELL, OF PORT SUNLIGHT, ENGLAND.

INSETTING ATTACHMENT FOR PRlNTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 655,399, dated August 7, 1900.

Application filed December 20, 1899. Serial. No. 741,028. (No model.)

To aZZ whom it may concern:

Be it known that LJOHN GASKELL,3 subject oft-he Queen of Great Britain, residing at Port Sunlight, in the county of Chester, England, have invented certain new and useful Improvements in Insetting Attachments for Printing-Presses; and I do herebyv declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which'it appertains to make and use the same.

This invention has for its object improvements in mechanism for duplicating the (lelivery of printed matter from printing or other machines in which the delivery of paper or substitutes thereof can be accelerated; and it consists in providing means whereby printed matter can, even in double-folded form, the one part inset within the other, be effectually accomplished in and by the means hereinafter fully set forth. It has heretofore been customary in the delivery of such folded printed matter to deliver the same in single form by fliers operating throughout an angle of ninety degrees, but according to this invention the travel of the fliers is throughout an arc of one hundred and eighty degrees and at half the speed of the former. However, I will now proceed to describe my said invention with reference to the accompanying drawings, which form part of this specification.

Figure 1 is an end elevation. Fig. 2 is a plan. Fig. 3 is a side elevation, partly in section, taken on line 3 3, Fig. 2, looking in the direction of the arrow and showing the bevelgear of one hopper in full lines and the hop per in rear of the gear and in vertical transverse section.

Reference being had to the drawings and the letters thereon, A A are the receivinghoppers, into which the folded printed matter is delivered at a central point into a fixed inclined receptacle 0 O of a V shape formed at that point in the sides of the semicircular hopper A A. The bed of the said hopper A is provided with concentric openings 0 0 throughout an arc of one hundred and eighty degrees, as shown. Through these slots or openings 0 c fingers d protrude, said fingers d being formed on or attached to fliers B B, mounted on a vertical axis. This axis is provided with a pinion r, to which motion is imparted by the reciprocal movements of a rack q. The folded printed matter on being delivered into the said V-grooves will spring open to the angle of the grooves of the receptacle O C in'the hopper A or thereabout and will remain so until a second folded printed sheet is delivered from the same machine and within the open folds of the first folded and printed sheet. At this point the oscillating fliers B sweep the two out of range while another pair are being delivered into the angular receptacle, whereupon the return of the fliers takes the next pair of folded sheets along to the other trough, and so on with every delivery of the machine.

The speed of the shafts operating the fliers B B as now in ordinary use is hereby reduced one-half in order to allow the fliers to make one oscillation in the time now taken by an ordinary machine to make two, While by so doing it allows the first folded sheet of printed matter to remain at rest, supported in the V-grooves herein described, during one-half the period taken by the fliers B B to make one oscillation. This is attained by means of gear-wheels in a corresponding ratio and advantageously in the following manner:

D indicates a frame supporting a countershaft f, on one end of which is an eccentric having a rod 72., which connects with the lever 1', attached to the rock-shaft 70, which is provided with a miter gear-wheel Z, meshing with a like gear-wheel m on shaft n, and to which shaft is attached a lever 0, connected to a bar 19, having gear-teeth g, which engage with a sector-shaped gear-wheel r on shaft 5, to which the flier B is secured. On the opposite end of the counter-shaft f is a crank-disk t, having a wrist-pin u, to which is attached a rod 1), which connects with a lever '10, attached to the rock-shaft 2 which is provided with a miter gear-wheel s, meshing with a like gearwheel a on shaft b, and to which shaft is attached a lever 0, connected to a bar d, having gear-teeth e, which engage with a sector shaped gear-wheel f on shaft 9, to which the flier B is secured. On one end of the counter-shaft f is a master gear-Wheel h, which meshes with a pinion '5, secured to a shaft E. The counter-shaft f works in suitable bearings f, supported by a bracket D, bolted down in a convenient manner at the delivery end of the printing or folding machine, or both, as the case may be.

Motion is given to the rocking shaft- 70 by means of an eccentric g and crank 11 through the levers 7t and t', which in turn give motion through the miter-wheels Z and 'm to the vertical shafts n n, and thence by the reciprocal movement of the rack 12 and pinion r to the fliers B B aforesaid. I

In the foregoing examples the delivery of the printed and inset matter has been effected by a radial action for convenience in having the delivery ends of the hopper side by side; but I would have it understood that I do not confine myself to such radialaction, as it may be efiected by a reciprocating set of fliers in a straight path to feed each end thereof. The plane of the base of said straight hopper need not necessarily be horizontal, but may be advantageously inclined, so as to retard their movement along the hopper somewhat, and thereby cause a greater number of bundles to accumulate in a given space than would be the case were it open or horizontal. It will be obvious that these oscillatory or reciprocal movements can be efiected by various forms of mechanism as modifications of the means herein shown and described and to which I would have it understood that I do not confine myself; but

What I claim as my invention, and desire to secure by Letters Patent, is

1. An insetting attachment for printingpresses, consisting of'a hopper having a fixed transverse receptacle constructed to receive a folded sheet of paper and allow it to open and receive an insert leaf; in combination with a flier for removing the paper from said receptacle and from the hopper.

2. An insetting attachment for printingpresses, consisting of ahopper having a fixed transverse paper-receptacle provided with inclined walls to receive a folded sheet of paper and allow it to open and receive an inset leaf; in combination with a flier for removing the paper from said receptacle and from the hopper.

3. An insetting attachment for printingpresses, consisting of a hopper having a fixed transverse paper-receptacle to receive a folded sheet of paper and allow it to open and receive an inset leaf, and a slotted bottom; in combination with a flier having fingers pro- ,iecting through the slots in the bottom for removing the paper from said receptacle and from the hopper.

' 4. An insetting attaohmentfor printingpresses, consisting of a hopper approximately semicircular in form and having concentric slots in its bottom, and a paper-receptacle crossing the hopper; in combination with a flier having fingers projecting through said slots, and means for imparting vibratory motion to the flier for removing the paper.

5. An insetting attachment for printingpresses, consisting of a hopper having a transverse paper-receptacle; in combination with a flier, a rack and pinion for operating the flier, and means for reciprocating the rack to impart vibratory motion to the flier.

6. .An insetting attachment for printingpresses, consisting of a hopper, a paper-re ceptacle; and a flier; in combination with a rack and pinion, and suitable gearing and connections for lessening the speed of the flier one-half of that of its main drivingshaft, to permit the flier to travel through an arc of one hundred and eighty degrees and thereby efiect a delivery on both its forward and return movement.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN GASKELL.
