4 Claims.

This invention relates to vibratory apparatus and more particularly to a mechanical jogger for receiving and quickly aligning the edges 01 a stack of like sized sheet stock, such as paper sheets.

While the general idea of paper jogging ma chines is not new, presently available machines have certain disadvantages which are eliminated by my machine.

One important object of my invention is to provide a jogger which holds the stack of paper being jogged, thus eliminating the present day requirements that the operator hold the paper and that the operator have considerable skill to do so properly.

Another object is to provide a jogger which is light in weight and easily portable as opposed to commonly available joggers weighing from 100 to 250 lbs., yet which will properly collate a given amount of paper sheets in less time than presently available joggers. This reduction in weight is made possible by isolating the vibrations in the paper holding cradle, thus eliminating the necessity of providing an extremely heavy base to absorb the vibrations.

A second object is to provide a jogger which is so constructed and designed as to impart extremely rapid extremely short vibratory and rocking motions to the paper holding cradle, primarily due to the type and relative location of th cradle suspension, and to the location of the vibratory power unit used.

Still another object is to provide a jogger which automatically ejects paper dust and cuttings from the cradle as it operates, thus eliminating the accumulation of such debris and its consequent interference with the proper jogging or collating of the paper sheets.

Another object is to provide a novel means of resiliently suspending the paper holding cradle to obtain more rapid spring back, or return of the cradle toward its normal at rest position during each vibratory cycle, without transmitting violent vibrations to the table, desk or other support on which the unit is operating.

General description Generally my jogger includes a hollow paper holding cradle having a bottom wall and an end wall which meet at right angles, and two parallel upright side Walls. A power operated vibrator is mounted exteriorly on the bottom wall of this cradle approximately midway between its ends, with the rotational axis of the vibrator substantially parallel to the bottom wall. The cradle and its attached vibrator form a cradle assembly which is resiliently suspended and supported in space between two upright sides of a rigid hanger, which is adapted to be supported on a desk or table. The suspension occurs along a substantially horizontal plane which passes through the cradle unit above its center of gravity, and which extends fore and aft of its center of gravity. When the cradle is properly suspended in accordance with this invention, its bottom wall is inclined with relation to the horizontal. Th center of gravity of the cradle assembly, the center of vibratory forces created by the vibrator, and the center of cradle suspension lie in a common vertical longitudinal plane, and lines connecting them would form a triangle in that plane. The center of suspension lies in substantial vertical alignment with the center of vibratory forces, and both are spaced slightly forward or rearward from the center of gravity. Since the vibratory forces are created by a weight mounted eccentrically on one end of the shaft of an electric motor, the forces are lateral or transverse, as well as in a vertical plane.

As a result of the described cradle suspension and vibrator mounting, the vibratory motion imparted to the cradle varies at different points and is extremely efiective in quickly aligning the edges of a large stack of paper sheets. The motion produced at the upper or aft end of the paper supporting bottom of the cradle is almost entirely a transverse or lateral reciprocating motion. The motion produced at the upper or forward end of the cradle end wall is almost entirely vertical reciprocating motion. The motion produced at the junction of the bottom and end walls is substantially circular, and in a plane which is substantially parallel to the inclined end wall of the cradle. It is therefore evident that this suspension permits motion of the cradle in three planes.

The invention will be more clearly understood when the following detailed description is read in connection with the accompanying drawing, in which:

Fig. 1 is a lateral sectional view through a jogger embodying my invention, and is taken along the line [-4 of Fig. 2;

Fig. 2 is a longitudinal sectional view through the jogger, and is taken along the line 2.-2' of Fig. l;

'ig. 3 is an isometric view of a cradle suppor shelf which constitutes a part of the invention.

Details of construction In the. drawings numeral I0 designates a paper holding cradle as a whole. It includes an inclined bottom wall I I, an inclined end wall I2 which meets the bottom wall at right angles, and two upright parallel side walls I3 and I 4. Perforations I 5, I6, and I1 are provided in the bottom and end wall to permit paper dust and fine cuttings to be ejected from the cradle during its vibration, thus preventing the accumulation of such debris from interfering with the proper aligning of the edges of the sheets. The cradle I is provided with a pair of oppositely disposed parallel elongated angle strips I8 and I9, which are secured to the respective side walls I3 and I4 by suitable means, such as screws 20. Each angle iron strip has one flange projecting outwardly in a horizontal plane, as shown in Fig. 1, the bottom II lying at an angle to this horizontal plane.

An electric motor 2I having an eccentric weight 22 attached to its shaft, is mounted on the exterior surface of the bottom -II by means of screws 23. The motor is mounted so that its rotational axis lies at an angle to the horizontal flanges of the angle strips I8 and I9, and also lies in a fore and aft vertical plane which passes through the center of gravity of the cradle. It is also preferably positioned so that the weight 22 is located either forward or aft of a vertical line passing through the center of gravity of the cradle assembly, which includes the attached motor.

A hanger assembly, designated as a whole by the numeral 24, is provided for resiliently suspending the cradle assembly in space. The hanger proper may be of cast metal or may be of sheet stock, as shown. It includes a horizontal bottom 25 provided with suitably spaced rubber feet 25, and two spaced parallel upright side walls 21 and 28. These side walls are spaced apart a distance slightly greater than the distance between the outer parallel edges of the L horizontal flanges of the angle strips I8 and I9.

A pair of inwardly projecting oppositely disposed parallel horizontal shelves are rigidly mounted along the upper edges of the side Walls 21 and 28, one on each wall. Short metal screws 29 are used to secure the shelves in place, or they may be spot welded or otherwise secured. While these shelves may be in the form of simple angle strips, similar to the strips I8 and I9, but inverted, I prefer to make them in the form shown in Fig. 3. In this case each shelf is in the form of an elongated housing 30 which has a side opening 3| along its inner side wall, as clearly shown in cross section in Fig. 1.

As one means of resiliently suspending the cradle assembly from the hanger assembly to obtain the desired spring back or return of the cradle toward normal at rest position, two or more relatively thick elongated strips of sponge rubber 32-33, are cut to fit the interior of each shelf-housing 30, and are inserted through the openings 3| so that they lie in horizontal planes. The

side wall portions

34 and 35 serve to firmly hold the sponge rubber strips against lateral movement with relation to the shelf proper.

The outwardly projecting flanges of the angles I8 and I9 are inserted between two adjacent sponge rubber strips on the respective shelves, and the cradle assembly is thus resiliently suspended in space.

With such suspension it will be noted that while one end of the lowermost rubber strips 33 are absorbing a downward vibratory thrust transmitted to the cradle, the opposite ends of the upper strips 32 are also absorbing and resisting this motion and tending to return the cradle to normal at rest position. Also that as the cradle is returned toward at rest position the respective opposite ends of the rubber strips above and below the angle flanges act to snub and reduce this return movement.

In Fig. 2 the center of gravity of the cradle assembly (including the attached vibrator unit) is approximately indicated by the letter X, the approximate center of cradle assembly suspension is indicated by the letter Y, and the approximate center of vibratory forces created by the vibrator 2| is indicated by the letter Z. The ceners Y and Z are located almost directly one above the other, both lie forward of the center of gravity X, and all three lie in a common vertical longitudinal plane.

Since the axis of rotation of the eccentrically mounted weight 22 lies at an angle to the horizontal, forces emanate therefrom in planes substantially parallel to the cradle end wall I2. As a result of the described relative locations of centers X, Y, and Z, movement of the cradle at the upper end of its bottom II is almost entirely a transverse or lateral reciprocating motion. Motion produced at the upper end of the cradle end wall I2 is almost entirely a reciprocating motion in a vertical plane, and motion produced at the junction of the bottom II and end wall I2 is substantially circular in a plane substantially parallel to end wall I2, resulting in both a lateral and vertical movement. These motions combine to jog a stack of paper sheets in a manner which separates the sheets slightly from each other, and quickly allows two edges of each sheet to assume positions along the bottom II, and end wall I2, thus quickly aligning all four edges of like sized sheets. Paper dust and fine slivers from the edges of the cut sheets also gravitate toward the bottom I I and end wall I2 during the jogging operation, and are ejected through the holes I5, I8, and I1, so that such debris never interferes with the proper aligning of the edges of the sheets.
