8 Claims. (Cl. 271-89) This invention relates to a vibratory apparatus and more particularly to a mechanical jogger for receiving and quickly aligning the edges of stacks of like sized sheet stock, suchas paper sheets.

Joggers of present design employing vibrating table tops function satisfactorily .on paper of relatively heavy stock but are employed with somewhat lesser success in a stock of extremely light weight, :such as onion skin.

One of the objects of the present invention is a me dhanical jogger providing a pulsating forced air which might be directed between the sheets of a random stack- :ing of sheet stock to eliminate the previously encountered drag between the sheets being jogged.

A further object of the present invention is the provision of a jogger of improved design providing for ease of transportation and employment.

A further object of the present invention isthe provision in a jogger of a source of forced air also funct ioning as the means for efiecting the vibratory movement of the jogger table top.

Further objects and features of the invention will be readily apparent to those skilled in the art from the specification and appended drawings illustrating certain preferred embodiments in which:

Figure .5 is a sectional view taken along the lines VV =ofFigure 3.

The jogger 1 of the present invention rconstitutesa sheet metal box 2 havingwend, side and bottom walls and an open top. A vibrating surface 3 is provided above the box 2 upon which the jogging is accomplished. Re-

silient mounting .feet 4 are provided for the box 2 .along handles {5 -at eachend lot :the box for ease of .carrying and supporting. A snap switch 6 is provided in one side wall of the box 2 for the control of electrical energy to the power source for the jogger, all of which will be more fully described hereinafter.

At the upper surface of the box 2, the side and end walls are folded over to form a retaining lip at 7 supporting a plurality of cushion mounts 8 at positions around the interior of the box 2.

Within the box at each end thereof, a material of high mass 9 is provided adding stability and weight to the box of the jogger. This mass may be of any extremely dense material and, as shown in the drawings, may be of a molded concrete material.

Attached to the surface of the mass 9 are a pair of re- United States Patent. 0

side surface .of the squirrel cage rotor.

ice

2 .silient springs 10 fixed in a manner to be securely heldin the mass. As shown in the drawings, the mass being a "molded concrete material, the springs 10 are molded into the mass and securely held upon setting of the concrete material. The opposite ends of the springslll are secured to a cross member 11 by individual screws 12 extending through 'the cross member 11 and through la rubber :bushing 13 and into the interior of the spring 10 where a nut cooperates with the end of the screw and against a retainer ring 14 inengagement with at least one loop of the springs 10.

The cross members 11 are secured by suitablezscrews 15 to the under surface of the jogger table top 3 at :both sides and at each end of the box 2, and a resilient strip 16 is positioned betweenxthe upper surface of the crossmernber 11 and the under surface of the table 3. The previously mentioned bushings 8 are secured to the under surface of the table 3 as shown in Figure 4 by suitable screws 17 running into the under surface in a manner to ensure that the table does not bounce against the upper surface of the box 2 of the jogger.

Centrally disposed within the box 2 is a motor driven squirrel cage type fan having an involute tunnel through which forced air is passed to the under surface of the table top 3. The motor for the fan is shown at 21 and constitutes the conventional high speed, low voltage motor. 'The shaft 22 of the motor extends into the tunnel 23 of the fan and has secured thereto the squirrel cage rotor 24 having a plurality of fins 25 supported on a spider. 26. The exit port of the fan tunnel 27 is se cured by side channel brackets 28 to the under surface of the table top 3 by suitable screws 29 and is aligned with a. hole .31 through the table surface 3 with a wire mesh 32 positioned betwen the under surface of the table '3 and the exit port of the fan.

The fan rotor 24 is adapted to provide pulsating air through the hole 31 by substantially closing a major number of the fins 25 leaving only a relatively few shown at 33 in a position to cause increased air movement as they pass through the involute fan tunnel. In this manner a continuous stream of air having pulses with each revolution of the fan rotor is provided through the opening 31 through the table top 3.

The fan is also provided with a means for producing vibratory motion in the jogger, this constituting unbalancing weights .34 :secured by screws 35 to the fins at one With each revolution of the fan rotor, a vibration will be produced due to the offset weights causing the entire fan housing to vibrate at the speed of revolution of the motor and this vibration will be transferred to the table .3 of the jogger through the connection .of the fan to the under surface of the table top.

The operation of the jogger of the present invention should be readily apparent from the description of the parts constituting theassernbly wherein it can be :rea-dily seen that with each revolution of the squirrel cage rotor of the fan pulses of air will be forced through the opening 31 in table surface 3 and the table surface will be vibrated in rhythm with the rotation of the offset weights 34 of the fan rotor. The mass 9 supported within the box 2 of the jogger will maintain the box itself in a relatively stable position and the springs 11 will permit the table surface to vibrate without transferring the vibratory motion into the box.

In employing the jogger to align a bundle or stack of random placed sheets, the sheets may be placed on the table surface 3 and passed across the opening 31 where the vibration of the table will cause the sheets to be urged into alignment and where the pulses of air passing I the plane thereof.

through the opening 31 will pass between thesheetsin a rippling action to place a minute air cushion between adjoining sheets of the stack to eliminate friction between sheets and permit all sheets to drop into place in a stacking position. The jogging of even fine stock material maybe accomplished with extreme-ease in thatfalli'shee'ts of the stack will be separated bythe forced aircoming 'throughthe fan and each sheet may then independently if drop into alignment with the level surfaceof the table -top 3.

.While a certain preferred embodiment of the invention has been specifically disclosed, itis' understood that the invention is not limited thereto, as many variations will ;be readily apparent to those skilled in the'art and the invention is to be given its broadest possible interpretation within the terms of the following claims.
