'7 Claims.

The present invention relates to improvements in joggers for printing presses, paper outters and the like in which sheets of paper of uniform size are successively delivered upon a platform and are stacked one above the other.

The principal object of this invention is to provide a jogger that will stack the paper sheets with their edges in exact alinement and registry so that when the stack is completed it may be removed from the platform without any rearranging. While joggers have been used before in connection with printing presses they have not been satisfactory insofar as they failed to bring about exact alinement and registry of the edges of the sheets and it has always been necessary to rearrange the sheets by hand before the stack was ready for packing or for putting back into the feeder of the printing machinefor further printing operations.

A further object of the invention is to provide a jogger of the character described that is simple in construction and may be readily attached to any type of printing machine without difiiculty.

A further object of the invention is to provide a jogger that may be easily adjusted to any desired size of sheet, within its range.

A still further object of the invention is to provide a jogger in which the jogging elements or guides engaging the edges of the sheets are made to carryout at least two back and forth movements for each new sheet deposited, on the stack.

It is further proposed to provide an actuating mechanism for the jogging elements that is particularly efiicient and causes the elements to move in synchronized order.

Further and other objects and advantages of our invention will appear as the specification proceeds.

The preferred form of our invention is illustrated in the accompanying drawings in which Fig. 1 shows a top plan view of our jogger,

Fig. 2, a front view of the same,

Fig. 4, a vertical section taken along line 44 of Fig. 1,

Fig. 5, a vertical section taken along line 5-5 of Fig. 1, and

Fig. 6 a vertical section taken along line 66 of Fig. 3.

While we have shown only the preferred form of our invention We wish to have it understood that various changes or modifications may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

Referring to the drawings in detail, our jogger l is intended for use in connection with a printing machine well known in the art of which only parts are shown, namely the front section of the platform 2 on which the printed sheets discharged from the machine are deposited, the grippers 3 which successively deposit the sheets on the platform as they come from the printing machine and the bar 4 which reciprocates along one of the side edges of the platform. This bar forms part of the conventional carriage on which the grippers are supported and therefore is timed to reciprocate once for each sheet delivered by the grippers 3.

Our invention comprises in its principal features a base 5, a plurality of jogging elements or guides 6, 'l, 8, and 9, movably disposed thereon and an operating mechanism for these elements.

The base 5 is preferably rectangular in form, of a size somewhat in excess of the largest sheets to be handled by the machine and is secured to the platform 2 at the place of delivery of the sheets by any suitable means as for instance by the screws Ill. The base is preferably made of light metal, such as aluminum and comprises a relatively thin plate II formed with downwardly projecting flanges I2 around the border and central ribs l3 and cross-ribs l4 connecting with a central ring-shaped rib l5. Inside of the latter we provide a ring l6 of harder, wear-resisting material, such as steel, the thickness of this ring corresponding to the combined thickness of the plate and the flanges and the ribs, which latter two are of equal thickness so that their bottom faces lie in the same plane.

The four jogging elements or

guides

6, 1, 8, and 9 are made in the form of rectangular upright plates and arranged so as to receive between the same the sheets deposited on the base and to contact the sheets along the four edges thereof. Each of the elements is adjustable to its position toward and away from the center so that they may be adjusted to accommodate any size of 5 sheet within the range of the machine.

Since each of these elements has its own operating mechanism they will be taken up one by one. The element 6 is the rear element, that is, the one nearest to the machine and it rests on sleeve Il riding in a groove 18 and secured to a rod H! which extends clear from the rear wall of the base to the front wall. The groove l8 lies over and within the rib l4 and is rectangular in cross-section. The sleeve I1 is of the same shape as the groove and is slidable therein. The sleeve is held to the rod by means of the set screw 20, this arrangement corresponding to that shown in section in Fig. 3, in connection with the guide 8.

The rod I9 is made in two sections which are joined together within the ring l6 by means of the coupling or wedge 2| and the front end of the rod is normally made to project, under the influence of the spring 22, hearing on the rear wall of the ring l6 and a washer 23 held in position by a pin 24, beyond the front end of the base, as shown at 25.

The projecting end 25 is received in a recess 26 in the bar 2'! which latter is free to slide along the front wall of the base and is mounted in a block 28 secured to the front edge of the base. The block is co-extensive in length with the front edge of the base and is secured thereto by the screw 29 at one end and a cover plate 30 at the other end. It is suitably groved to slidably receive the bar. The recess 26 has a cam face so that when the bar moves to the left, as seen in Fig. 1, it forces the rod I9 backward, while on the other hand the spring actuated rod [9 will force the bar to the right as soon as the bar is free to move in that direction.

The bar projects beyond the right edge of the base and carries a roller 3| which latter is actuated by a wedge 32 on the reciprocating bar 4 to push the bar inwardly, and it should be noted that the wedge 32 actuates the bar 26 on its return stroke as well as on its forward stroke.

The guide 6 therefore operates as follows: As the member 4 plunges forward, it causes the bar 21 to be pushed to the left (see Fig. 1) and the cam face of the recess 26 pushes the rod l9 backward and with it the guide 6. After the point of the wedge 32 has passed the bar 21 the latter is free to return and the spring 22 pushes the rod and with it the guide 6 forward while the rod bearing on the cam pushes the bar to the right. On the backward stroke of the member 4 the same action takes place so that the guide jogs back and forth twice for one back and forward movement of the member 4, and since the latter is timed to move back and forthonce with the delivery of each sheet, it will be seen that the guide 6 jogs back and forth twice for each sheet delivered.

The two guides 1 and 8 which in many respects are similar to the guide 6 are mounted on the two

rods

33 and 34 for sliding movement in the

transverse grooves

35 and 36. The inner ends of these rods bear upon the two cam faces of the wedge 2| and are forced outwardly thereby when the wedge 2|- (on the rod I9) moves backward, while two

springs

31 and 38 move the rods inwardly when the wedge moves forward. Thus the two guides l and 8 move outward and inward in synchronism with the guide 6.

The guide 9, which has the paper release springs 9' thereon, is operated differently. Instead of being secured to the rod l9 itself it is secured, by means of the set screws 20, to the sleeve 39 slidable on the rod and this sleeve is made to move in a direction opposite to that of the rod. The sleeve is urged forward by a spring 40 and backward by a lever 4| pivoted underneath the base plate as at 42 and having one arm bearing on the guide (underneath the sleeve 39) while the other arm is actuated by a pin 43 secured underneath the bar 26. When the bar 26 moves to the left, the spring 40 urges the guide 9 outward and when the bar 26 moves to the right, the pin 43, through the lever 4|, moves the guide inward, so that the guide 9 moves outward and inward in synchronism with the other three guides, all the guides making two complete back and forth movements for each sheet delivery.

This double action causes each sheet to become perfectly alined with the underlying stack and when the stack is removed from the jogger it will be found that all the sheets are in perfect registry.

For alining the jogger to different sizes of sheets, the guides may be moved along their respective rods upon loosening the set screws 20 and 20' respectively. For work of very small size the device may be further adjusted by means of an auxiliary plate 44 adjustably mounted in front of the guide 6 by means of shafts 45 passing through embossments 46 projecting from the guide. Set screws 41 are provided for holding the shafts in place.
