SPECIFICATION forming part of Letters Patent No. 570,580, dated November 3, 1896.

Application filed August 8,1895. Serial No. 558,595. (No model.)

To all whom it may concern.-

Be it known that I, FREDRICK H. WENDT, a citizen of Sweden, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Packers for Use on Folding- Machines; 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.

This invention relates to packers for use on folding-machines; and it consists in certain improvements in the construction thereof, as will be hereinafter fully described an d pointed out in the claims.

This invention is illustrated in the accompanying drawings as follows:

Figure 1 is a side elevation of the packerboard with the packer-head and parts of its actuating mechanism, showing relative position of parts. Fig. 2 shows a perspective view of the packer-head and actuating mechanism. Fig. 3 shows a plan view.

A marks the packer-board, A A the side guides thereon, and A the packer-back. A supporting-rod O is attached to a part of the frame of the folder 0 by means of brackets c. The packer-board is carried by the supporting-rod O by means of a bracket a which is provided with a screw-operated clampingband (not shown) of usual construction, by means of which the board may be raised or lowered and set at any position along the rod 0. The side guides A are provided with setting apparatus a a, by means of which they may be set at any distance apart, according to the size of the page it is desired to pack.

The packer-back is provided with movable faces a a, carried on slide 0, a set in the packer-back, and these faces can, by means of these slides, also be adjusted in and out to vary the width of the packer-back, so as to accommodate it to difierent sizes of pages.

The packer-board proper is set with its inner end just in front of the delivery-line eof the rolls E E. Two projections A extend from the end of the board on a level therewith under the delivery-line and through the packer-head B. The paper as it comes from the rolls is caught by these projections,

from which it is carried onto the packer-board as the packing progresses.

The packer-head B is carried by the headrod 6. This head-rod 1) slides in guides c, at- 5 5 tached to the frame C, and is connected by a link I) to a rock-lever b pivoted at 22 The end of the rock-lever is acted upon bya cam B, so as to reciprocate the connecting parts and the head to carry it toward the packer- Go back. The packer-head is returned to normal by a spring B acting through the rod 13 on the rock-lever 11 The projections A pass through the opening 12* b in the head, which construction allows this movement.

Just at the front of the delivery-line e are two stop-fingers D. These fingers arecarried by finger-rods cl and have normally a position inclining toward each other at the top and are of such length as to allow the passage of the arms I) at the top of the head over them. The head has inclined sides to allow it to pass between the fingers. The fingerrods cl are journaled in bearings c and are provided with rock-arms (Z d, one extending above one arm and the other below the other arm. These rock-arms are connected with a link 02 so that the rocking of either arm rocks the otherarm in an opposite direction, and the fingersD D are opened or closed together. A rock-arm (1 extends from one of the fingerrods cl and is connected by means of a link 01* with a rock-lever d pivoted at d. The rocklever d is actuated by a spring D so as to throw the fingers D D apart. A cam D, acting through the rod D upon the lever d returns the fingers D D to normal.

The operation of the device is as follows: The cams B and D are actuated by moving parts of the folder mechanism. The cam 13' is so timed in its action on the lever 12 as to start the packer-head just after each delivery from the rolls. Just before the head reaches the fingersD D the cam Dturns, so as to allow the spring D to open the fingers D D, and

the paper passes between them. The head in this movement is pressed forward, so that its front face comes at least flush with the front face of the fingers and preferably just sufficiently forward of flush with the fingers to allow the fingers to move freely back of the paper. As soon as the paper passes the fingers D D the cam D throws the fingers back of the paper under the arms 11 thus retaining the folded sheet until the next foldsection is received in the packer. The cam B then moves out of contact with the lever b and the head is returned to normal by the spring B IVhen it is desired to pack smaller-paged sheets, the board is elevated and the side guides and packer-back adjusted. The head and stop-fingers, by reason of the inclination of the sides of the head and the fingers, will operate on the smaller pages Without further adjustment.

The board A is preferably set at such height that the paper will just clear the rolls as it is packed. By such an adjustment there is less liability of the paper getting out of its proper position, as is the case with the stationary boards, and consequent long drops on the smaller sizes.

In previous constructions of packers with which I am acquainted the packer-head and the mechanism incident thereto have been attached to or supported by the packer-board,

, and consequently have been raised and lowered with the board or readjusted when the board has been raised or lowered. In my construction the board is raised or lowered to accommodate difierent sizes of paper, and by reason of the inclination of the fingers and the fact that the head and its mechanism are not supported by the board, but independently supported, no change or adjustment of the head and its operating mechanism is necessary to accommodate them to the new position of the board.

\Vhat I claim as new is 1. In a packer the combination of the packer-board means of adjusting said board to difierent heights; side guides on said board; means of adjusting said guides to different widths of folded sections; a packer-head having inclined sides and means which said packer-head passes for stopping a return movement of the paper.

2. In a packer the combination of the packer-board; means of adjusting said board to different heights; side guides on said board;

means of adjusting said guides todifferent 5o widths of folded sections; a packer-head having inclined sides; and automatically-actuated and normally-inclined stop-fingers which said packer-head passes.

In a packer the combination of the packer-board; the packer-head; means of imparting motion to said head; stop-fingers between which said head passes; and means for automatically actuating said fingers independently of the action of the fold-section being packed the movement of said head and fingers being timed for the fingers to open, the head to pass through said fingers while open, the fingers to close after the head has passed through but before its return movement, the head to return through the closed fingers.

4. In a packer the combination of the packer-board; means of adjusting said board to different heights; the packer-head means of actuating said head; normally-inclined stop-fingers automatically actuated toward and from each other between which said head passes and means of supporting and actuating said fingers independently of said packerboard. V

5. In a packer the combination of the packer-board; means of adjusting said board I to diiferent heights; the packer-head; means of supporting and reciprocating said head independently of said board; stop-fingers inclined toward each other; and means of actuating said stop-fingers out and in as the head passes them for the purposes set forth.

6. In a packer the combination with the board; the packer-head and means for imparting movement to said head; of the stopfingers D D; rods cl d; means of actuating the rods d cl to rock in opposite directions; and means for rocking said rods d in timerelative to the movement of said packer-head.

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