Carl S. Weyandt, Homer City, Pa. Application March 18, 1946, Serial No. 655,258 Q a claims. (ci. 271-89) This invention relates generally to paper joggers having a high speed vibrating table or deck on which uneven stacks of paper can be caused to flow smoothly into even stacks and more particularly to paper joggers which provide a lateral movement and a combined vertical and lateral movement to the stack of paper being jogged into a smooth and even stack.

Paper jogging presents several problems most of which are due to the character of paper being jogged and some owing to the job to be accomplished in conjunction with production in the paper handling art. In preparing small stacks of paperv for storage, packaging or trimming, wherein the stacks are manually manipulated with ease and do not form a step in a continuous production program, a deck which vibrates at high speed in a vertical or rectilinear path nor- This type of paper jogger is disclosed in patent applications Serial No. 441,561, led May 2, 1942, now Patent No. 2,398,777, dated April 23, 1946, and Serial No. 609,416, led August 7, 1945, which has matured into Patent No. 2,463,448, March 1, 1949. The table or deck is disposed in a horizontal plane and the paper stack is jogged on one edge then turned and jogged on another edge to produce the even stack.

However, if the jogging problem represents a fast step in a continuous production system or requires the simultaneous jogging of a series of stacks oi' paper that are to be combined or require rapid supply the vertically vibrating deck type paper jogger is unable to ill the requirements.

The principal object of this invention is the provision ci' a paper jogger wherein the deck is provided with an edge board or fence and is vibrated to produce aform of lateral movement to jog two edges of a stack of paper simultaneously in a lateral direction avoiding the necessity of turning the stack.

However all forms of lateral motion will not function to jog the same kinds of paper lying iiat in relatively small stacks. A combined vertical and horizontal movement of a horizontal deck will cause the under sheets of the stack to move in one direction while the upper sheets move in the opposite direction. 'Ihus another object of this paper jogger having a deck with corner edge boards and which vibrates only in a path parallel to the deck.

Another object is the provision of a paper jogger having a deck which rapidly vibrates in a fixed path at an angle to the Another object is the provision of a horizontally disposed deck which rapidly vibrates in a xed path at an angle to the surface of the deck.

Another object is the provision of an edge board for a paper jogger deck.

Another object is the provision of a plurality of guides which work in conjunction with an edge board of a paper jogger deck for jogging a plurality of paper stacks simultaneously.

Another object is the provision of a sloping paper jogger deck which rapidly oscillates in a. horizontal path.

Other objects and advantages appear in the following description and claims.

In thel accompanying drawings practical embodiments illustrating the principles of this invention are shown wherein:

Referring to Fig. 1 of the drawings, I represents an enclosed metal cabinet constructed of sheet metal mounted on an angle iron frame 2.

surface of the deck. 55

The cabinet is a, oor model and is provided with four rubber feet 3. The horizontally disposed deck or table top 4 is approximately thirty-six inches from the oor. A table model paper jogger of this character is constructed in the same manner but the cabinet is short to properly locate the height of the working surface or deck. The right end of the deck 4 is provided with an edge board or barrier 5 which extends the full width of the deck and is secured thereto. The deck and the edge board are preferably made oi hard wood and when the use of the paper jogger is extensive the Wood deck and deck board are preferably covered with sheet metal or a fairly heavy coating of soft rubber as indicated at E. However the deck should be very rigid.

The deck has the heavy metal plate 1 secured to the underside thereof for the purpose of fastening the thick wide strap 8 thereto, the

ends of which depend at an angle to the deck.

The vibratory motor I consists of a massive base casting II supported by four coil spring feet i2 on the angle frame 2. The heavy base casting II is provided with spaced seats disposed at an angle to the vertical to receive and clamp the fore and aft resilient spring members I3 and I4 which are secured at their other ends to the ends of the strap 8. is resiliently supported by the springs I3 and I4 which are wide fiat strips.

The electromagnetic motor comprises a field member I5 and an armature member IE. The laminated core of the field member is riveted to the crossbar I1 that is bolted to the base II.Y

This core is E shaped and the formed coil I8 is mounted on the center stem. The armature IS is straight and extends the full width of the core of the iield member and is secured to the depending end of the strap 8, by the same fastening means that secured the spring I3. in spaced relation to the three poles of the field member. The armature I6 is made up of a laminated structure when rectified alternating current f is/employed to operate the motor but is a polarized armature when ordinary alternating current is employed.

Since the springs I3 and I4 are parallel and are mounted normal to the movement of the armature and the horizontally disposed deck 4 is supported at an angle relative to the movement of the armature, the vibratory movement of the armature moves the deck downwardly to the left and the springs I3 and I4 return it to the normal position. The armature is attracted to the field 3600 times a minute when the motor is operated from a sixty cycle alternating current but it is not permitted to contact the pole faces. This resultant movement of the deck 4 provides a vertical and a horizontal component and the disposition of the motor is arranged to provide a greater horizontal component than a vertical component. However the magnitude of vibration is relatively small. This motion causes the paper stack that is held on edge, with the laminae normal to the edge board 5, to flow smoothly against the board 5 and bring the edges of the paper into an even and uniform stack. Thus the stack of paper becomes Jogged on both edges at the same time.

The ileld member IB of the motor I5 is energized from a suitable alternating current source by the lead wires and plug 20. One wire is connected to one side of the knee switch 2l and thence to one end of the rectifier stack 22 made up of copper oxide or selenium washers stacked in one direction. 'The other end of the rectifier stack is connected to one end of the coil I 8 and the other end of the coil is connected to the rheostat 23 the end of which is connected to the other side of the line. Thus the half wave al- Thus the entire deck 4 1 ternating current circuit may be completed by closing the switch 2I.

In the structure shown in Figs. 2. 3 and 4 the steel cabinet 24 is constructed on the angle frame 25 which is provided with a shelf 2B upon which is secured therubber spring members 21 that resiliently support the massive base 28 oi the vibra- -tory motor 30, which is larger than the motor I5 shown inFig. 1 and provides supports for the deck 3| that are spaced materially greater to enable the deck to carry a heavier load. The aft deck supporting spring 32 is dual as shown 'in Fig. 2 and their lower ends are secured to the base 28 while their upper ends are secured to the bracket 33 welded to the plate 34 that is secured to the underside of the deck 3| between the spaced rails 35 and I6. The fore deck supporting springs are built into the motor and resiliently support the amature in spaced relation from the pole faces of the field in a manner similar to that shown in Fig. 1. The armature is then secured to the plate 34 by the bracket 31 and vibrates the deck in a path parallel to the disposition of the motor but at an angle to the deck.

The edge board 4I! extends the full width of the deck and has a T slot 4I in the top thereof to receive the heads of the bolts 42 which are employed to clamp the plates 43 that carry the paper guide partitions 44. The plates 43 are made Integral With the partition 44 and carry the whole or the partition from the edge board, maintaining the b ottom edge of the guide partitions spaced from the deck surface. The free end of each guide partition carries the adjustable and rotatable paper guide hook 45 the `balls of which may be wider than the paper stacks to be jogged. The hooks 45 are held in sockets by friction and may be turned to press against the outer side of the stack, thus tending to move it toward the adjacent partition. A single partition and ibail can hold up the paper stack if it is thin and small enough to pass under the bail while it is being jogged against the deck and the edge board, permitting the operator to prepare a second stack. However a plurality of paper guides mounted on one edge -board employ their respective guide hooks to maintain the stacks against the adjacent partition and a series of stacks may be :logged simultaneously and removed and replaced in consecutive order.

The rectiiier and the rheostat may be built in the controller unit 46 which is shown suspended in the frame 25 in Fig. 2 and the machine may be started and stopped -by the knee switch 2| The paper jogger shown in Figs. 5 and 6 is provided with the vibratory motor Il] shown in Fig. l. However in place of mounting the motor within a cabinet it is supported -by three rubber spring members 41, 48 and 49 on the frame 54 constructed of the parallel rails 5I, 52 attached at the fore end to the long cross rail 53 having the rubber feet 54 adjacent the ends thereof. The aft end of the rails 5I, 52 are connected by the angle plate 55 as well as the spring member 41. The third and rear leg 56 has the-rubber toot 51 and' a series of holes so .that it may be attached to the intermediate portion of the angle plate 55 by the bolt 58 and wing nut 59 to adjust the height of the rear end of the motor I0 to tilt the deck 50 at an angle to the horizontal. The deck 6l! has the edge boards 6I and 62 which meet at the lower corner 63 and a diagonal line between the corners 83 and 64 of the deck is substantially aligned with the axial center of the motor I0. As previously stated, if the deck is held in a horizontal plane the under sheets in a horizontally disposed stack will creepto the lett while the top sheets will overcome this action the deck 60 is tilted until the resultant. force is substantially horizontal as shown in Fig. or at a steeper angle as provided for by the height of the rear leg. 56. With the resultant force being substantially horizontal or dipping to a greater degree large sheets of paper lying iiat on the deck 168 will 'be logged into the corner 63 against the edge boards 6I, 62.

In Figs.i 7 and 8 the |base 66 is provided with the two pairs of spaced and upwardly extending lugs 61 and 68. The spaced resilient spring members 10 and 1| are made from iiat strips and are secured at their ends to the respective pairs of lugs 61 and 68. The deck 12 is provided with spaced depending brackets 13 and 14 which are secured to the springs 10 and 1| intermediate `their ends to resiliently support the deck 12 parallel with the base 66. The'corners of the deck 12are set diagonally relative to the vbase 66 as shown in Fig. 8 and provided withthe edge boards or fences 15. A bracket 16 depends from lthe underside of the deck 12 to support the'armature 11 which is mounted to provide a magnetic coupling between the armature 11 andthe electromagnetic eld 18 which is supported by the bracket 19 on the base- 66. The vibratory motion of the deck 12 is in a single plane parallel with the base 66 Winch may be held in a tilted position by the leg 56.
