14 Claims.

This invention relates to a jogging machine for straightening sheets in a stack with the edges thereof in registry with each other, and has for its principal object to provide a machine of this character which is of simple construction and efficiently brings the guide edges of the sheets into precise registry.

Other objects of the invention are to provide a jogging machine with a vibratory table mounted on its supporting frame so that the vibrations are not transmitted through the frame to the building structure in which the machine is housed; to provide a machine wherein the mechanical connections between the actuator and the jogging table are constructed for silent operation and to further reduce objectionable transmission of the vibrating forces; and to provide a jogging table particularly adapted for jogging light weight stock such as india, manifold tissue, carbon and onion-skin papers without frilling or curling of the edges.

It is a further object of the invention to provide a jogging table capable of simultaneously jogging a plurality of piles of sheets.

In accomplishing these and other objects of the invention, I have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawings, wherein:

Referring more in detail to the drawings:

1 designates a jogging machine constructed in accordance with the present invention, and which includes a relatively rigid base having suflicient weight in the body thereof so 'as to provide a stable support for the machine, and so that the inertia thereof is sufiiciently great to avoid transmission of vibrations to the building in which the machine is housed.

The base of the machine includes a plate-like body 2, having a footing flange 3 whereby the base is adapted for stable support on a floor. The center of the plate portion is preferably provided with an opening 4, and extending transversely thereof is an axle shaft 5 carrying wheels 6 and 1. The ends of the axle are carried. in bearing brackets 8 adapted for vertical movement within guide sockets 9 upon manipulation of jack-screws l0 so that the base may be moved relatively to the wheels 6 and I to raise the base from the floor and facilitate movement thereof when the machine is to be moved from one location to another.

Extending upwardly from the base are sockets H and I2, rigidly receiving the ends of posts l3 and [4 for supporting the jogging table, later described. The upper ends of the posts are preferably flat and adapted to be clamped to a supporting frame l5 by clamp screws IS.

The frame I5 is of substantially rectangular form and includes a top I! having a substantially rigid rim I8 depending therefrom, whereby the frame is of substantially rigid construction and free from any fiexure incidental to vibration of the jogging table I9. The opposite sides of the frame are provided, substantially on the longitudinal median line thereof, with internally threaded sockets which register with openings 2| in the flat ends of the posts to pass threaded shanks 22 of the clamping screws IS. The clamping screws have head portions 23 provided with collars 24 to engage the outer faces 25 of the posts and to cause clamping engagement of the inner faces 26 of the posts with the side faces 21 of the frame when the shanks 22 are threaded The heads 23 of the clamping screws are provided with levers 28 whereby the screws may be readily manipulated to clamp the supporting frame at a selected angle between the posts, as clearly shown in Fig. 2.

The jogging table l9 includes a rectangular frame 29 having side bars 30 connected by end rails 3|, are

parallel bars

33 and 34 spaced apart I a distance slightly greater than the width of the supporting frame and which extend parallel with the sides thereof so that one of the corners 35 of the jogging table is positioned so a bisector thereof extends at substantially right angles to the tilting axis of the supporting frame, as shown min Fig. 6. The frame is provided with a top board 38 that is rigidly secured thereto by suitable fastening devices as indicated at 31. Secured to u the side and end rails forming the corner 35, and Y projecting outwardly therefrom, are brackets 38 {and 39 having flat faces 48 and ll respectively registering with the ends of the supporting frame as shown in Fig. 6. Carried by the diagonal bar 34 is a similar bracket 42 located in alignment with the bracket 38 at the opposite corner of 'iothe supporting frame. The corner at the opposite end of the supporting frame is cut away, as indicated at 43 so as not to project beyond the side wall 38. Extending from the table, adjacent the juncture of the diagonal 34 and the intermediate rail 32, is a similar bracket 44 having a side face 45 thereof registering with the side face of a similar bracket 48 projecting from the side of the supporting frame.

Connected with the side faces of the brackets.

thus described are spring leaves 41, spacingly retaining the table in spaced parallel relation with the supporting frame, the upper ends of the -..leaves being secured to the respective brackets by fastening devices 48, having the shanks 89 thereof extending through clamping blocks 58, through openings 5| in the leaves, and into threaded sockets 52 of the brackets, whereby, when the fastening devices are tightened, the heads rigidly clamp the blocks against the spring leaves and the spring leaves against the flat faces of the brackets. The lower ends of the spring leaves are secured to the frame by similar fastening devices 53. The table is thus resiliently supported by the spring leaves, and since the spring leaves are arranged in planes extending transversely of the pivotal axis of the supporting frame, the table is adapted to vibrate with respect to the supporting frame with the bisector of the corner 35 shift:

. ing relatively to the tilting axis.

Carried by the side and end rails forming the corner 35 are a plurality of guide stakes 54 for engaging the guide edges of the sheets to be jogged, as later described. Depending from the sides of the supporting frame and offset from the bisector of the corner 35 is a parallel shaft 55, having its ends suitably joumalled in

bearing brackets

58 and 51 depending from opposite sides of the supporting frame. Mounted on the shaft is a pulley 58 that is driven by a belt 59 operating over the drive pulley 68 of a motor 8| which is suspended below the supporting frame, as shown in Fig. 3. Also fixed on the shaft, adjacent the supporting brackets, preferably by keys 62, are eccentrics 83 journalling eccentric straps 84 on needle bearings 85. Carried by the sides of the supporting frame are stub shafts 86, the stub shafts being preferably provided with, reduced tapered shanks 81 engaged in tapered sockets 88 of the frame and which are drawn tightly therein by nuts 89 mounted on threaded ends 18 of the tapered shanks. Carried on the stub shafts by needle bearings II are rocker arms 12 and l3 having weighted ends 14 and upwardly extending arms I5 offset with respect to the axis of the stub shafts as shown in Fig. '7. The weighted ends 14 are notched substantially in alignment with the horizontal plane extending through the axis of the rotating shaft to form seating faces 16 cooperating with similar faces 11 on lugs 18 of the eccentric straps to attach spring leaf connectors 19, the leaf connectors being rigidly secured to the respective faces by fastening devices 88 having the threaded shanks thereof extending through clamping blocks 8|, through the ends of the leaves, and into threaded sockets 82 as clearly shown in Fig. '7.

Secured to the under side of the jogging table, in alignment with the rocker arms, are brackets 83 having the lower faces 84 thereof substantially registering with the upper faces 85 of the arms 15 to be connected by spring leaves 88, the spring leaves 88 being retained by

clamping plates

81 and 88, having flanges 89 engaging over the, ends of the leaves and lapping the opposite faces of the brackets 83 and arms 15 respectively. The clamping plates are rigidly secured in position by fastening devices such as cap-screws 98, having their threaded shanks extending through openings in the plates, through registering openings in the ends of the spring leaves and into threaded sockets as shown in Fig. 7.

Rotation of the eccentrics incidental to actuation of the shaft oscillates the rocker arms and effects vibration of the jogging table, whereby sheets placed in a stack on the table, as indicated in Fig. 1, are caused to shift against the stakesat one side when the table moves in one direction, and then against edges of the stakes at the other side when the table moves in the opposite direction, resulting in alignment of the stake-engaging edges of the sheet.

The motor for actuating the eccentric shaft is energized through a switch SI mounted on the base and having an operative connection through a link 92 with a foot treadle 83.

In order to prevent the guide edges of the sheets from curling and climbing up the stakes, selected stakes are provided with hold-down clips as shown in Fig. 9, which clips float freely on the stakes and bear upon the margins of the sheets as the sheets settle thereunder incidental to vibration of the table. The clips are preferably formed of a single piece of wire bent at spaced points 94 and 95 intermediate the ends thereof to form a cross bar and

vertical leg portions

96 and 91, the lower ends of which are bent on an angle, as at 98 and 99, to form throats or guides whereby an applied sheet settles under the arms I88 and IM which bear on the sheet. The arms are of suflicient length to extend to the rear of the stakes and terminate in inwardly directed portions I82 and I83 connected with vertical portions I84 and I85, the ends of which are bent to form a loop I88 loosely engaging the stake whereby the portion I88 and IM bear upon the sheet with the projecting portion, including the legs 98 and 81, acting as a weight. As shown in Fig. 10, the stakes are inclined outwardly at a slight angle relatively to the table so as to avoid and character of the stock being jogged. This is effected by lessening the clamps and tilting the frame, after which the clamps are retightened. The operator then places his foot on the treadle to effect energization of the motor for rotating the eccentric shaft. Rotation of the shaft v-ibrates the table through the rocker arms and spring leaf connections so that the table moves relative to the frame on the spring leaf supports 41, the table oscillating with sufficient rapidity so that when a sheet is placed on the table it will settle into the angle-shaped pockets formed by the corner 35 with the side edges engaging the stakes. As succeeding sheets of paper are fed onto the table, the guide edges thereof will be automatically moved to registry with the edges of the first sheet to produce a stack with all of the edges in precise registry. The weight portion of the rocker arms balance the moving parts of the table so as to dampen vibrations tending to cause the entire machine to vibrate, thereby avoiding the objection and noise incidental to jogging devices with which I am familiar.

From the foregoing it is obvious that I have provided a jogging device which is of simple construction and which efficiently registers the edges of loose sheets.

Fig. 11 shows a different stake arrangement. In this arrangement two sets of stakes I01 and I08 are mounted on the table so that two piles of sheets may be jogged simultaneously. Otherwise the machine is constructed in the same manner as the one above described.
