8 Claims. (Cl. 271-89) This invention relates to a paper jogging machine and more particularly to such machine utilizing a vibratory motion to align the edges of a stack of paper sheets.

Conventional paper jogging machines usually include a vibrating table, platform, or paper-holding tray supported on springs and employing an electric motordriven eccentric weight attached to the vibrating table. One disadvantageous feature of such machines is that, in -order to properly jog or collate a stack of paper sheets of substantial thickness, it is necessary to employ very strong springs to support the weight of the platform, tray, and paper. The required strength of the springs increases the stilfness of the springs to a degree that a considerable portion of the vibrating action is transferred j to the jogger cabinet and thereby to the entire machine to cause unwanted movement of the machine across, and sometimes off, a desk or other supporting structure. While this disadvantage may be remedied by extremely massive cabinets to absorb the vibratory action tending to move the machines, the considerable weight of the cabinets is undesirable due to the increase in manufacturing costs and difficult portability of the machines. Another objectionable feature of such machines is that the paper-holding tray is supported in a fixed vertical position preventing easy loading of the paper sheets on the tray, as the sheets tend to curl and fall to one side of the tray.

. One important object of the invention is to provide an improved paper jogging machine which is light in weight, readily portable, and produces effective vibratory action to properly and quickly collate the paper sheets while transferring negligible vibratory action to the cabinet or to its support.

Another object of the invention is to provide an irnproved paper jogging machine in which the weight of the paper holding tray and its load is partially supported for vibratory movement by a resiliently `supported platform, and partially by an independent resiliently supported panel, thus permitting a reduction in the stiifness of resilient members supporting both the platform and the panel, and minimizing the transmission of vibrations to the supporting base `or cabinet.

Another object of the invention is to provide an improved jogging machine of the type described in which an auxiliary spring ysuspension for the paper-holding tray lpartially supports the tray and its load while the full force `and effect of the vibrating action of the table is transmitted to the tray.

A further object of the invention is to provide an improved paper jogging machine of the type described in which an auxiliary load-supporting panel is supported on springs independently of the spring suspension of the vibrating table and tray, and cooperates with the table to aid in supporting the tray and its load.

A further object of the invention is to provide an improved paper jogging machine featuring a paperholding tray pivotally connected to and depending down- ICC ward from an edge of the vibrating table for pivotal movement to `an inclined or tilted position to facilitate loading of paper sheets in the tray and thereafter to a Vertical position for quickly collating the paper sheets during vibratory action of the machine.

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

Fig. l is a longitudinal sectional view through a jogging machine embodying my invention, and is taken along the line 1-1 of Fig. 2; thepaper-holding tray being shown in an inclined position;

Fig. 2 is a lateral sectional view through the jogging machine, and is taken along line 2--2 of Fig. l;

Fig. 3 is a side elevation of the jogging machine with the paper-holding tray shown in vertical collating position, portions of the machine being `broken away and Ishown in longitudinal section to more clearly illustrate the various parts of the machine; and

Fig. 4 is an isometric View of the paper-holding tray and its auxiliary spring support.

In the drawing the numeral 10 designates a paper holding tray as a Whole. The tray includes an. inclined end Wall 11, an inclined end wall 1Z meeting the end wall 11 at right angles, and an upright side wall 13 connected to the tw'o end walls. The end Walls are preferably sheet metal and formed to provide angularly disposed aligned

anges

14 and 15, respectively, and parallel to the side wall 13 to contain the paper sheets in the tray. The side wall 13 has a plurality of arcuately shaped

notches

16, 17 and 18 for facilitating removal of collated paper sheets. The side wall 13 of the tray may be formed of wood for connection by screws to one leaf of a hinge 19 of the piano type, the other leaf being secured by screws to the top of a wood table or platform 20 connected to a vibration-producing structure supported within a cabinet, indicated generally at 21.

The cabinet 21 is formed of thin sheet metal and includes a horizontal bottom wall 22, and. two spaced parallel

upright side walls

23 and 24 which may be formed as integral portions of the bottom wall 22. Each side wall has inwardly turned angularly disposed end flanges, the rear flange `on the side wall 23 being indicated at 25 and the rear ange on the wall 24 being shown at 26. Projecting laterally of the spaced front flanges of the

walls

23 and 24 are triangularly shaped supports bolted to the anges, one ofthe supports being indicated at 27. The supports are provided with rubber ball-shaped feet, such as shown at 28, cooperating with

similar rubber feet

29 and 30 secured to the bottom wall 22 to resiliently support the jogging machine on the ilat surface of a desk or table.

The open upper ends of the side walls are capped by and support horizontal

elongated channel strip

31 and 32. Below the

strips

31 and 32 and disposed within the

side walls

23 and 24 are

angle strips

33 and 34 secured to the side walls by bolt and nut assemblies :as shown in Fig. 2. The

strips

31 and 33, and side wall 23, form a housing for two sets of superposed relatively

light springs

35 and 36. Similarly, twfo sets of superposed

springs

37 and 38 are disposed within a housing formed by the side wall 24 and strips 32 and 34. The spring sets are located in spaced relation to each other with two spring sets being disposed at opposite ends of the

strips

31 and 33 and the other two spring sets located at opposite ends of the

strips

32 and 34.

The springs cooperate with the

strips

31 and 33 of the cabinet to resiliently suspend and support the vibrationproducing structure comprising the table 20, an electric motor 39, and an eccentrically-weighted pulley 40 driven `by the motor. More particularly, spaced parallel elongate channel-section strips 42 and 43 have their top walls secured to the bottom of the table 20 by screws 44, the bottom wall of the strip 42 extending between and being engaged by the

superposed springs

35 and 36, and the bottom wall of the strip 43 being disposed between the

springs

37 and 38, as shown in Fig. 2. To prevent displacement of the springs, the upper springs may have their reduced upper end coils secured to the engaged

strips

31 and 32 vby nut and bolt :assemblies 45 as shown, and the lower springs have their bottom end coils similarly secured to the

strips

33 and 34 by nut and bolt assemblies 46. A bracket 47 is fastened to the bottom of the table 20 by screws 48, the bracket having spaced parallel arms provided with aligned bearings receiving a shaft fixed to the pulley 40 provided with an eccentric weight 49. The pulley is rotated by the electric motor 39, fastened to the bottom of the table, and drivingly connected by a belt An important feature of the present invention is the y provision of an auxiliary spring suspension structure to aid in supporting the weight of the paper holding tray 10 and its load, and to aid in absorbing vibrations imparted to the tray 10 by the table 20. The structure illustrated is of the cantilever type.

This structure includes a flat elongate sheet metal panel or support 52, the inner end of which is transversely pivoted within housing 21. At its inner end support 52 is secured to the upper ange 56 of a transverse channel section strip 55 =by means of bolt and nut assemblies, as shown in Fig. 1. The other ange 57 of the channel section strip 55 is mounted between laterally spaced pairs of

rubber washers

58 and 59, the washers being held in position by bolt and nut assemblies 60. The holes in flange 57 through which the bolts 60 project are elongated in `order to provide a free pivotal movement of the panel 52 about a tnansverse axis.

The other end of panel 52 projects beyond the front of the cabinet 21 and terminates in a down turned lip 65. This panel 52 is supported in the inclined position shown in Fig. 1 by means 0f a pair of laterally spaced

springs

61 and 62. The lower ends of these springs are anchored to and supported by a transverse plate 64 which in turn is spot welded or otherwise secured to an inwardly projecting iiange at the front of the cabinet proper. The springs are anchored by means of metal screws or by bolt and nut assemblies, as shown. The upper ends of the springs bear against a transverse angle section strip 63 the central portion of which is spot Welded directly to the panel 52. The upper ends of the

springs

61 and 62 are anchored to the strip 63 by metal screws. A transversely disposed stop 68 in the form of an angle section strip has one flange secured to the panel support 52 by spot welding or by any other suitable means.

Before the operation of the machine is described it should be noted that tray 10 is provided with three

rubber feet

66, 69 and 70 (Fig. 4) which are located to rest on the upper surface lof the spring suspended support 52 when the tray assumes a vertical position, as clearly illustrated in Fig. 3. Foot 66 is mounted on a centrally located tangle strip 67, which is secured by rivets to tray wall 13. Feet 69 and 70 are similarly mounted on an angle plate 71 which is secured by rivets to tray flanges 14 and 15 (Fig. 4).

Operation Before loading the tray with paper to be collated, the operator grasps the angle plate 71 at the lower end of the tray and pulls the bottom of the tray outward and upward to the position shown in Fig. 1. In this position rubber foot 66 rests on lip 65. With the tray in such an inclined position paper sheets may be placed in the tray and will lie flat against side wall 13, with no tendency whatever for the sheets to curl.

Motor 39 is then started and the previously described vibrating structure immediately imparts vibrations to table 20, and through hinge 19 to the tray and its load of paper. The vibrations imparted to the tray, plus the pull of gravity due to the load of paper in the tray, cause the tray foot 66 to gradually move down the inclined panel support 52 until the two outer feet 69 and 70 also rest at on the upper surface of panel support 52, as clearly shown in Fig. 3. Stop plate 68 is contacted by foot 66 and further inward pivotal movement of the tray 10 is prevented. The vibratory action of the machine is 1allowed to continue until all paper in the tray is completely collated.

It will be noted that during the above described collating action the weight of the tray 10 and its load of paper is supported not only by the

springs

36 and 38 but also by the

springs

61 and 62. By thus increasing the total number of springs used to support the total weight of the table 20, the tray 10 and its paper load, the springs used may be much more flexible and resilient than otherwise. By using lighter weight and more ilexible springs the vibratory motions transmitted to table 20 and to the tray 10 are much more effective. Furthermore, by making the panel 52 and its supporting springs entirely inde* pendent of the spring suspension which supports the table 20, the vibratory motions required for properly collating the paper in tray 10 are much more easily absorbed and prevented from being transmitted to the cabinet 21. Consequently, any tendency of the cabinet to Walk across its supporting surface is eliminated. As a result there is no necessity for the ycabinet to be made of heavy material. Instead, it can 4be made of light weight sheet metal so that the entire jogger is easily portable.
