PAPER-FEEDING MACHINE.

SPECIFICATION forming part of Letters Patent, No. 475,839, dated May 31, 1892.

Application filed August 18, 1891. Serial No. 402,968. (No model.)

V as the sheets are fed off from the top of the pile, a buckling-finger whereby the sheet is buckled, holdingdown fingers against which the sheet is buckled, a pile-retaining finger whereby the pile is held in place, and devices for carrying the buckled or loosened top sheet from the pile to the printing-press or other machine. Heretofore the buckling of the sheet was effected by a f0rward-andbackward movement of the buckling-finger parallel with the rear edge of the sheet. It has been found desirable in feeding certain kinds of paper to buckle the sheet obliquely, or on a line'running approximately diagonal from the corner of the pile.

The objects of my invention are to provide a simple and efficient device whereby the buckling-finger is moved in a diagonal direction; also, to produce a device whereby the movement of the buckling finger can be changed from a direction parallel with the rear edge of the sheet to a diagonal direction, or vice versa.

In the accompanying drawings, consisting 'of three sheets, Figure 1 is a front elevation of the sheet-buckling mechanism. Fig. 2 is a top plan view of the same. tudinal section of the buckling-finger on an enlarged scale. Fig. a is a top plan view of the bucklingfinger, showing the same straight and in itsretracted position. Fig. 5 is a similar view, partly in section, showing the buckling-finger moved forward and deflected to its oblique position. Fig. (i is a vertical crosssection in line a: 00, Fig. 4. Fig. 7 is a fragmentary vertical section in line .2 .2, Fig. 2, on an enlarged scale. Fig. 8 is a horizontal see- Fig. 3 is a longition in line on 00, Fig. l, on an enlarged scale, showing the trip-arm in its normal position at right angles to its line of motion. Fig. 9 is a similar section in line 1 y, Fig. 1, on an enlarged scale, showing the trip arm in its shifted position obliquely to its line of motion. Fig. 10 is a vertical section in line a .90, Fig. 2, on an enlarged scale, showing the spring-bolt in the trip-arm retracted.

4 Like letters of reference refer to like parts in the several figures.

A represents the vertically-movable feedtable upon which the pile of paper is placed and which is raised automaticallyin the usual manner as the sheets are fed from the top of the pile.

B represents the carrying-head, which supports the parts of the sheet-buckling mechanism and which is secured to the rear end of a supporting-rod l).

0 represents the longitudinal driving-shaft, which is journaled in the lower portion of the carrying-head and which imparts motion to the buckling mechanism.

D represents a depending rock-arm provided at its lower end with a buckling-finger E, which receives a backward-and-forward movement from the rock-arm. The buckling finger bears upon the sheet and buckles the same while moving forward and is raised from the sheet during its backward movement. The rock-arm D, carrying the bucklingfinger, is pivoted at its upper end on a lug d, projecting from the upper end of the carrying-head. A transversely-oscillating motion is imparted to the arm D by means of a crank a, secured to the end of the driving-shaft and connecting with an inwardly-extending arm 6 of the rock-arm D by a link 6 O F represents the preliminary holding-down finger, against which the top sheet is buckled by the initial portion of the forward stroke of the buckling finger. This preliminary holding-down finger has a vertical movement toward and from the top of the pile of paper and is provided with actuating mechanism, whereby it is held on the pile of paper and lifted therefrom just before the advancing buckling-finger reaches it.

G represents a gage-foot, which rests upon the pile of paper and is arranged at a distance inwardly from the preliminary holdingdown finger. This foot serves the double function of regulating the upward feed motion of the pile-supporting table and of a holding-down finger, against which the top sheet is buckled when the latter has been released by the preliminary holding-down finger. The gage-foot has a vertical movement toward and from the pile of paper, so as to release the sheet and allow it to be fed off from the pile.

11 represents the vertically-movable pileretaining finger, which bears upon the corner of the pile of paper in rear or outside of the buckling device and holds the pile in place while the top sheet is being removed.

The pile-retaining finger, the preliminary holding-down finger, the gage-foot, and their actuating device and the device for moving the buckling-finger back and forth and lifting it on its return stroke are the same as those described in Letters Patent of the United States No. 434,629, dated August 19, 1890, to which reference is hereby made for a more complete description thereof.

The buckling-finger is preferably provided with a roller 1, journaled in the bifurcatedinner end of a horizontal rod or stem 2' in such manner that it is held against turning during its forward movement, but allowed to revolve during its backward movement. The outer end of the rod or stem of the buckling-finger is'provided with a hinge-plate J, which is arranged between two lugsjj, formed on the inner side of an eye K, which is jo'urnaled on a horizontal arbor 70, secured to the lower end of the depending rock-arm. The hinge-plate of the buckling-finger is pivotally secured be tween the lugs of the eye K by a vertical pin passing through the outer ends of thehinge-plate J and lugsjj near the rear sides thereof. The eye K, journaled on the horizontal arbor of the rock-arm, and the hinge,

when the buckling-finger is straight and lim-- its the forward swinging movement of the buckling-finger on its vertical pin in the absenceof any other device for the purpose.

L represents a bearing-plate formed on the front side of the hinge-plate J, and extending above and below the latter, so as to strike against the inclined front sidesj of the lugs jj, thereby limiting the backward swinging movement of the buckling-finger.

Z represents a coil-spring arranged lengthwise over the front portion of the bucklingfinger and attached with its ends to pins arranged near the front sides of the lugj and the hinge-plate J, whereby the buckling-finger is yieldingly held in its straight position, or in line with the direction of thetransverse movement of the depending rock-arm.

M represents an upright rock-shaft whereby a horizontal oscillating movement is imparted to the buckling -finger. This rock -shaft is j ournaled in bearings m m, secured to the depending rock-arm D, and provided at its lower end with a crank m, which bears against the front side of the bearing-plate L of the buckling-finger. The rock-shaft M is held against lengthwise movement by means of collars N N, secured to the rock-shaft above and below the upper bearing m. The upper collar N is provided with a stop at, which overhangs the outer side of the upper bearing and limits the forward movement of the rock-shaft by striking against the plate of the upper bearing, as represented in Figs. 1, 2, and 8.

0 represents a horizontal trip-arm whereby the rock-shaft is oscillated. This trip-arm extends rearwardly from the lower collar and is preferably formed integral therewith. The

'trip-arm is made hollow and provided with la spring-bolt P, which slides therein and is adapted to strike against a fixed stop Q on the carrying-head during the forward movement of the buckling-finger.

1] represents a spring surrounding the contracted rear portion 19' of the spring-bolt in the trip-arm and bearing against shoulders 19 23 formed, respectively, on the inner sides of the trip-arm and the spring-bolt, whereby the latter is normally held in a projected position.

The rear end of the trip-arm is provided with a longitudinal slot 19 in which moves a guidepin 13, which is secured to the spring-bolt and whereby the latter is prevented from turning and which also limits the projecting movement of the spring-bolt. The front end of the spring-bolt is provided with an abrupt front 1 and an inclined back g. This causes the trip-arm to be deflected when the abrupt face strikes the stop Q and the spring-bolt to recede without deflecting the trip-arm when the inclined back strikes against the stop.

The latter consists of an angle-plate r, which is adj ustably secured by a screw to a bracket R, arranged on the carrying-head. The a11- gle-plate is provided with a flat face r and an inclined back 1- against which latter the inclined back of the spring-bolt engages dnring the backward movement of the trip-arm. At the beginning of the forward movement of the depending rock-arm the buckling-finger rests upon the pile of paper and the springbolt strikes with its flat face against the flat face of the fixed stop, as represented in Figs.

3 1, 2, 3, 4,. and 8. During the further forward movement of the rock-arm the stop Q obstructs the forward movement of the trip-arm and causes the free end of the latter to be retarded or swung backward, whereby the upright rock-shaft is turned backward, as represented in Fig. 9. This turning movement of the rock-shaft causes the crank at its lower end to bear against the bearing-plate of the buckling-finger, thereby causing the latter to be swung on its hinge and to be deflected out of its straight course and to travel over the sheet obliquely, or at an angle to the line of movement of the rock-arm, as represented in IIO Fig. 5. During the oblique inward movement of the buckling-finger the spring Z becomes strained. Then the buckling-finger has nearly completed its forward movement, the trip-arm has been deflected sufficiently to permit its spring-bolt to pass the stop. It now again assumes its normal position, which is represented by dotted lines in Fig. 9. As soon as the trip-arm is released the spring Z draws the buckling-finger forward into the straight position indicated by dotted linesin Fig. 5. The buckling-finger remains in this .position during its entire backward or outward movement, and the trip-arm passes the stop, owing to its spring-bolt receding upon striking the inclined back of the stop. The oblique forward movement of the buckling-finger over the sheet causes the latter to be buckled diagonally, which is more desirable than the parallel buckling movement in feeding some kinds of paper. The trip-arm of the rock-shaft and the fixed stop on the carrying-head are arranged at a sufficient distance below the pivot of the depending rockarm that the travel of the rock-arm at that point gives the trip-arm and the buckling-finger the requisite amount of oblique movement in moving forward over the pile. By adj usting the stop the trip-arm can be deflected more or less, thereby causing the bucklingfinger to buckle the sheet ata greater or less angle. If desired, the sheet may be buckled parallel with the side of the pile by withdrawing the spring-bolt and locking it in its retracted position, so that it cannot come in contact with the stop. A simple locking device for this purpose consists of a notch 8, formed in the rear end of the trip-arm. The bolt is locked by withdrawing it to such an extent that its guide-pin p can be engaged in this notch upon giving the bolt a partial turn. Upon retracting the sliding bolt and holding it out of engagement with the stop during its forward-and-backward movement with the buckling-finger the latter moves across the pile parallel with the end of the pile, or in line with the transverse movement of the rockarm.

T represents a lifting-rod whereby the buckling-finger is raised from the pile during its backward movement, as represented in dotted lines, Fig. 3. This lifting-rod is attached with its inner end to the link connecting the rock-arm with the crank of the driving-shaft and passes with its opposite end through a post 25', arranged on a lug 25 formed integral with the eye K.

My improved buckling mechanism produces an oblique ordiagonal movement of the buckling-finger without changing the ordinary position of the driving-shaft and other actuating parts, which are arranged parallel with the sides and ends of the pile or pilesnpporting table, so that these parts can be driven and adjusted with the same facility as in a mechanism having only the straight movement of the buckling-finger.
