Referring more in detail to the drawings:

The reference numeral 1 generally designates a jogging machine having a jogging table structure 2 with a plura ity of table levels such as an upper table portion 3,

3,391,929 Patented July 9, 1968 a lower table portion 4, a sub-table 5, a base 6, and an extensible means 7 for elevating and lowering the jogging table structure 2 and the sub-table 5.

The jogging machine 1 includes a relatively rigid base 6 of suitable size to provide a stable support for the machine, said base having a heavy plate-like member 8. In the structure illustrated there are a plurality of spaced adjustable base supports 9 with each consisting of a floor pad 10 connected to a screw shank 11, each of which is threaded into a threaded bore 12 in the heavy plate-like member 8. The base 6 has spaced upright guide members 13 such as tubular or sleeve members suitably secured to the base and which are illustrated as having flanges 14 suitably fixed on the heavy plate-like member 8 by suitable fastening devices such as screws 15. The guide members 13 each have bores 16 for slidably receiving guide posts 17 as later described.

The sub-table 5 is maintained in vertical spaced relation to the base 6 by elongate bars 18. The elongate bars 18 are held in selected relation and engagement with said sub-table 5 at their upper ends by suitable fastening devices such as clamping screws 9 with each having a slidably mounted handle, or lever 20, mounted in a head portion 21 and a threaded shank 22. The threaded shanks 22 of the clamping screws 19 are received in opposed threaded sockets 23 of the sub-table 5. The opposite or lower ends of the bars 18 are suitably connected to a beam 24 as by screws 25. In the illustrated structure the screws 25 have a head 26, washer 27, and a threaded shank 28. At opposed ends of beam 24 are flanges 29 which have threaded sockets 30 which receive the threaded shanks 28 of the screws 25. Upper ends of the guide posts 17 are suitably connected to the beam 24 as by welding.

The sub-table 5 is preferably of thick cast metal and of substantially rectangular form to provide a substantial rigid construction free from any fiexure incidental to any vibration of the jogging table structure 2. The opposite sides of the sub-table 5 are provided substantially on the longitudinal median line thereon with the internally threaded sockets 23, which register with bores 31 in the bars 18 to receive the threaded shanks 22 of the clamping screws 19 which form trunnions 32. The head portion 21 of the clamping screws 19 engages the outer face of the bars 18 and hold same in engagement with the side edges of the sub-table 5 whereby the sub-table 5 may rock or tilt relative ot the bars 18 but doesnot have lateral movement relative thereto.

The jogging table structure 2 at the lower table portion 4 includes a rectangular frame 33 of connected members such as side bars 34 connected by end bars 35 and suitably braced as by cross bars 36. Supporting the frame 33 is a sub-frame 37 which includes connected side bars 38 and end bars 39. The sub-frame 37 is supported in substantially parallel relation to the sub-table 5 and in vertical spaced relation thereto. The sub-frame 37 is movably supported from the sub-table 5 by spring leaf connectors 40. The spring leaf connectors 40 are connected to the side bars 38 of the sub-frame 37 and to the sub-table 5 with suitable fastening devices such as screws 41.

The sub-table 5 and the jogging table structure 2 may be tilted about an axis 42. The axis 42 is aligned with the median line of the sub-table 5 which is defined by the trunnions 32. The threaded shank 22 of the clamping screw 19, the threaded sockets 23 of the sub-table 5, and the bore 31 in the bars 18 are aligned with the axis 42. When the clamping screws 19 are loosened, the subtable 5 and the jogging table structure 2 may be tilted to a selected position. The clamping screws 19 are then tightened to hold the sub-table 5 and the jogging table structure 2 in position with the bars 18, the clamping screw head 21 and the sub-table in clamping engagement. When the jogging table structure 2 and the subtable 5 are tilted about the axis 42, a corner 43 of each of the upper table portion 3 and the lower table portion 4 is lower than any other point on the respective table portion. The corner 43 has a bisector which is substantially perpendicular to the axis 42.

The sub-table 5 is provided with a vertical bore 44, having an antifriction bearing 45 therein for rotatably mounting a shaft 46 which extends vertically through the sub-table 5. The shaft 46 rotates about an axis that is essentially perpendicular to the sub-table 5. The shaft 46 is preferably offset from the bisector of the corner 43 and is substantially on the median line of the sub-table 5 as defined'by the axis 42. A pulley 47 is fixed on the depending portion of the shaft 46 and said pulley is driven by a belt 48 operating over a drive pulley 49 mounted on a motor 50, said motor 50 being suspended below the sub-table 5 by a bracket 51. An eccentric 52 is adjustably secured to the portion of the shaft 46 extending upwardly above the sub-table 5 whereby said eccentric 52 is rotated by the shaft 46 and operates an eccentric strap 53 journaled on the eccentric 52.

Extending upwardly from the sub table 5 are spaced rocker arms 54 journaled on stub shafts 55. The stub shafts 55 are preferably spaced on opposite sides of the axis 42 and in alignment with the bisector corner 43. The eccentric strap 53 is connected to each of the rocker arms 54 by a spring leaf connector 56 with said spring leaf connector 56 being connected to the eccentric strap 53 and the rocker arms 54 by suitable fastening devices such as screws 57 at opposite ends of the spring leaf connectors 56. The rocker arms 54 are connected to brackets 58 by spring leaf connectors 59 which are connected to said rocker arms 54 and bracket 58 by suitable fastening devices such as screws 60 at opposite ends of the spring leaf connector 59. The brackets 58 are connected to the end bars 39 of the sub-frame 37 of the jogging table structure 2 by suitable fastening devices such as screws 61.

Rotation of the eccentric 52 by actuation of the shaft 46 oscillates the rocker arm 54 which oscillation is transmitted through the spring leaves 59 to the jogging table structure 2 to effect vibration of the upper table portion 3 and the lower table portion 4 of the jogging table structure 2.

The upper table portion 3 and the lower table portion 4 receive sheets 62 of paper, or the like. The sheets 62 on the jogging table structure 2 are caused to shift against and engage a guide or fence 63, at one side when the table moves in one direction and then against the guide or fence 63 at the other side when the table moves in the opposite direction resulting in the alignment of the guide engaging edges of the sheets 62. The arrangement of the leaf spring connectors 40 and the sub-table vibrating mechanism moves or vibrates the jogging table 2 transversely of a plane bisecting the corner 43 therefore, the movement of the sheets 62 is laterally to alternately engage opposite guides or fences 63, and when the table is tilted to lower the corner 43 the vibration of the table will cause gradual downward movement of the sheets 62 until adjacent edges thereof are engaged by the guides or fences 63, which form an angular corner pocket wherein the sheets are retained in engagement with the guides or fences 63 and do not become disarranged because of continued vibration.

The extensible means 7 which rapidly elevates and lowers the jogging table structure 2 to preselected levels includes a ram 64. In the illustrated structure the ram 64 includes a piston cvylinder structure having a piston rod 65 which has one end connected to the beam 24 as for example and is located at an intersection of the axis 42 and the bisector of the corner 43. The piston rod 65 and piston thereof operates in a fluid cylinder 66. In the illustrated structure the ram 64 is controlled by a valve 67 preferably of a conventional plunger four way valve structure, having a power source 68 and a fluid source 69. The cylinder 66 and the valve 67 are connected by upper and lower fluid lines 70 and 71 respectively. The cylinder 66 is suitably supported on the base 6 as by a flange 72 and suitable fastening devices such as screws 73. In the structure illustrated the ram 64 is actuated to change the height of the beam 24, the sub-table 5, and the jogging table structure 2 by operation of the valve 67. A counter (not shown), at a predetermined count activates the valve 67 by a signal and whereby the fluid pressure source forces fluid under pressure through one of the fluid lines 70 and 71 to the cylinder 66 where fluid is supplied to One chamber in the cylinder 66, said valve bleeding fluid from the other chamber of cylinder 66. When another signal is received from the counter (not shown) the valve 67 reverses and supplies fluid through the other of the fluid lines 70 and 71 to the cylinder 66. Change in amount of fluid in the chambers of the cylinder 66 elevates and lowers the piston 65. Limit switches (not shown) may be installed at any desired elevation to control the distance of travel of the piston 65.

The height of the jogging table structure 2 may be adjusted vertically for proper height relative to apparatus from which sheets are to be received by adjustment of the bars 18. Each of the bars 18 has a vertical slotted opening 74 through which the screws 25 are inserted. When the screws 25 are not fully tightened the jogging table structure 2 and the sub-table 5 may be adjusted vertically in the plane of the slotted openings 74. When the table is in desired position the screws 25 are fully tightened and there is a clamping engagement between the washers 27, the bars 18 and the flanges 29 of the beam 24. The height of the jogging table is determined by the height of the delivery apparatus such as a conveyor 75.

The guide posts 17 slide vertically within the guide members 13 to maintain the bars 18 and the slotted openings 74 therein in a substantially vertical plane. The piston rod 65 of the :ram 64 elevates the beam 24 which elevates the bars 18. The bars 18 thereby elevate the subtable 5 and the jogging table structure 2 in a substantially vertical plane. During lowering of the piston rod 65 the bars 18, the beam 24 and guide posts 17 lower in a substantially vertical plane.

It is desirable that a power source 76 and a switch 77 which operates the motor 50 be independent of the power source 68 which operates the valve 67 and the limit switches (not shown). In the structure illustrated the switch 77 is mounted on the opposite face of the motor support bracket 51.

When the jogging machine is in position the whole structure is leveled by the adjustable base supports 9. The piston rod 65 of the ram 64 is moved to its bottom position so that beam 24 is at its lowest possible elevation and the table is then adjusted in height in relation to the delivery apparatus such as by means of the conveyor 75. When the table is at the selected height the screws 25 are tightened to provide clamping engagement between the washers 27, the bars 18 and the opposed flanges 29 of the beam 24. The table is then tilted about the axis 42 to a selected angle and the clamping screws 19 are tightened to provide clamping engagement between the clamping screw heads 21 the bars 18 and the sub-table 5. The motor is then turned on by switch 77 to vibrate the jogging table structure 2.

Sheets 62 are delivered by the conveyor to the upper table portion 3 and when a predetermined number of sheets 62 are delivered to the upper table portion 3 a counter (not shown) activates the valve 67 by a signal. The valve 67 by supplying fluid to one opposed chamber and bleeding fluid from another opposed chamber of the cylinder 66 elevates the ram piston 65. The piston rod 65 continues to elevate until engaged by a limit switch (not shown), the limit switch stops the jogging table structure 2 at a preselected elevation so that sheets 62 may be received on the lower table portion 4. With the jogging table structure 2 in the elevated position the conveyor 75 delivers sheets 62 to the lower table portion 4, a counter then activates the valve 67 by a signal at a predetermined number and the table is lowered until the table position is reversed, or by lowering, the table is in the prior position. While the table is in its lowered position jogged stacks of sheets 62 are removed from the lower table portion 4 and when the table is in its elevated position jogged stacks of sheets 62 are removed from the upper table portion 3. Thus, allowing a relatively continuous operation of the jogging machine and a fuller utilization of labor.
