4'Claims. I c This invention relates to improvements in joggers. V

Heretofore jogging machines have been of heavy construction, cumbersome, complicated in structural details andexpensive to build and repair. It was to overcome these' objectionable defects in prior joggers thatthe present invention was conceived.

The main objects of this invention are to provide a novel, improved, inexpensive and transportable jogging machine; to provide such .a device which is adjustable and adaptable to sub- 'stantially all types of printing, binding and trimming machines and machines used in allied industries; to provide a device of this character which. may be constructed of wood or other light inexpensive material; to provide a device of this character having a pivotally operated tray disposed on a housing cover and having an oscil1at-.

ing action transmitted to it by means of a motor; to provide a device of this character having adjustable means to accommodate different sizes and weights of paper; to provide a device of this character in which the motion of the jogger tray is in a single plane normal to the single rigidly mounted tray supporting pivot located off geometric centerof the tray; and to provide a device of this character which is simple in construction, safe, convenient and simple to operate and readily adjustable to different sizes and weights of work.

An illustrative embodiment of this invention is shown in the accompanying drawings in which:

Figure 1 is a top elevational view of my invention.

Fig. '2 is a sectional view taken on the line 22 ofFig. .1.

Fig. '3 is a sectional view taken on the line 3-3 of Fig. l. 1

Fig. 4 is a vertical sectional view of the pivot member taken on the line 4-4 of Fig. 1.

Fig. 5 is a face view of the eccentric member.

Referring in detail to the drawings, the-housing generally indicated by the numeral l is preferably constructed of wood, or a similar light weight material and comprises a base 2, a pair of'side frame members 3 and 4, the upper edges of which are diagonally disposed, as clearly shown in Fig. 2, a front frame member 5 and a top or cover plate member 6 secured to the upper edges of the side frame members 3-4. It will be apparent from Fig. 2 that the top 6 lies in a diagonal plane.

A jogging tray generally indicated by the numeral 1 comprises a base 8, a side wall 9, a front wall I0, and an adjustable end frame H. The

end frame H comprises a pair of side walls J2 and I3 attached in any suitable manner .to base I 4. The entire end frame I I is adjustable toward and away from sidewall 9 and is held in position on base 3 by the bolt 5 and wing nut IS. The bolt I5 is inserted and seats in .any one of the spaced apertures lllocated in side. wall 10 in accordance with thesetting desired; v

The tray '1 is positionedin parallel relationship to the top 5 of the housing I and is spaced away therefrom by means of an anchor pivot, The anchor pivot is fully illustrated in Fig. 4, and comprises two flanged collar members I 8 and is having a shaft 28 common to both of'them. Col.- lar I9 is anchored to. shaft 20.by any suitable means, such as byrivet 2|, so as tomake. the

collar l9 and shaft 20 a single unit. .Collar l9 7 is secured to the underside of base 8 ofthe .tray 1- by any suitable means, such, as by screws 22 passing through apertures in the, flange portion ofcollar l9.. j

Collar I8 is anchored. to the lower face of top 6 vof the housing I bybolts 23 ,23 andnuts 24-24 which pass through apertures located in the flange of collar.l8. It thus becomes apparent that the tray 1 is piovtallyanchored to the housing l and that the collar l8 acts as a bearing for the shaft 20. p i 7 To prevent displacement and play in. the collar-bearing l8, .a retention collar 25 is secured to the shaft 20' by any suitable means, such as by a set screw 2%. It will be noted that thev pivotal connection is located off dead center, i. e.,v the vertical axis of both the tray and housing.

The oscillating action of the tray is accomplished by the mechanism located within housing I', and comprises a motor 21, connected to an-electrical source in the usual manner and is con.- trolled by switch 28. Motor 21 is anchored to base 2 in any suitable manner such asby bolts 29. A pulley wheel is attached to the motor shaft 3| in any suitable manner, such as by set screw (not shown). A large pulley wheel-32 is securedto one end of thedriven shaft 33 and is connected to the pulley wheel 30 by belt 34.

Shaft 33 is located forward of the motor and is journaled in bearingblocks 35-35 having oil cups 37-31 located on the upper surface of the blocks 35-35 to lubricate the shaft 33. The bearing blocks 35-35 are anchored to the support block 38 which is anchored'to the -base 2. A flange 35 having a collar-36"is'secured-to driven shaft 33 in an suitable manner at the end opposite pulley wheel 32. A rectangular plate 40 is secured to outer face of the flange 33 by screws l |4l and contains stub shaft 39 mounted on said plate 40 eccentrically of the axis of the shaft 33.

One end of link arm 42 is provided with an aperture in which said eccentric stub shaft 39 seats and extends therethrough. The distal end of shaft 39 is threaded and provided with a lock washer 44 and nut 45 whereby to retain the arm 42 on said shaft 39. The free end Q2 of arm 42 is threaded. A second link arm 13 is provided with a threaded bore 43' into which the threaded end 42' is loosely threaded as shown in Fig. 3.

A rod 45 is slidably mounted in spaced bearing blocks 4e se which are anchored to an upright supporting frame 41 in any suitable manner such as by bolts 48. One end of rod 45 extends beyond the forward bearing block and is pivotally secured to the free end of arm 43 by a bolt 59 and nut 58. It will be apparent from Fig. 3 that arm as and rod 45 are provided with aligned apertures through which the bolt 59 is loosely threaded. The arm 43 and rod 55 are spaced away from each other by a washer 5!. A pivot collar 52 is anchored to rod is, substantially medially oetween bearing blocks AG-45, by means of a bolt 53, which extends through suitable apertures in rod 45, and nuts 54. Washer 55 serves to minimize friction. It will be apparent Fig. 2

that the collar is pivotally mounted to said rod on an axis normal to the axis of said rod. The lower end of connecting shaft 56 is slidably held in collar 52, a set screw 5'5 being provided in the collar for locking the shaft to the collar during shipment so as to support the cantilevered end of the tray 1. The upper end of shaft 53 is fixed in the flanged collar 58 in any suitable manner, such as by set screw 53. Collar 58 securely attached to the underside of base 8 of tray 1 and extends downwardly into aperture 6t located in housing cover 6.

Power is transmitted from motor 21 to driven shaft 33 by means of the belt es. Driven shaft 33 rotates the flange 36 and its eccentrically positioned stub shaft 39 which in turn transmits motion to link

arms

42 and 43 and they in turn reciprocate rod 45 which imparts oscillating motion to the tray 1 by means of the connecting shaft 56 about pivot 20.

The material to be jogged is fed over and slides across the top edge of end frame I i, such method of feeding causing the sheets of paper, or other material used, to become separated by retarding and separating each sheet and thus allowing an air pocket to come between each sheet. By the action of the machine, the sheets are then jogged into the corner which is formed by the intersection of side walls 9 and It and formed into a uniform mass. I have found that my invention functions most efficiently when a motor of A to A; horse-power is geared down to operate from 400 to 800 R. P. M., depending upon the material to be jogged.

It will be apparent from the foregoing that by using the pivotal collar 52 and loose threaded connection between the

arms

42 and 43 all wobble motion usually present in apparatus of this character is eliminated and only a forwardly and backwardly oscillatory motion is imparted to the tray 1 about the axis of the pivot shaft 2@.

It will be understood that some of the details set forth may be altered or omitted without de parting from the spirit of the invention as defined by the following claims.

I claim:
