PAPER JOGGER.

Application led April 7,

My invention relates to paper adjusters, known in the trade as joggers which are used for the purpose otl straightening up the sides and edges of a pile or stack of paper discharged from the roll ot a multigraph or printing press.

The primary object of my invention is to provide a pneumatic paper jogger that will be positive in action and that can be adjusted to paper of various widths and lengths, and that can, also, be readily attached to and detached from machines now in use.

Another object of my invention is to produce a jogger that can be manufactured at a small cost and operates smoothly without j ar or vibration.

Other and further objects and advantages of my invention will be noted in the specilication, claims and drawings, in which- Fig'. l is a side elevation ot a mimeograph stand showing my device in operation.

Fig. 2 is a plan view ot the same.

Fig. 3 is a longitudinal cross-section.

Fig. l is a cross-section ot the compression cylinder and piston.

Fig'. 5 is a plan view of brackets by which my device is attached to the machine.

In automatic printing presses and multigraphs, as well as those operated by hand, the paper is discharged sheet by sheet, and owingl to air currents and the vibration of the machine, the paper does not 'tall in an orderly manner.

The purpose of the jogger is to cause the paper to be stacked in an orderly pile, having vertical sides. I-Ieretotore this has heen accomplished by means of a reciprocable member actuated by a bell crank or some other form of lever arm, and a .spring of rela.- tively strong tension for returning the reciprocating clement. The result ott this construction causes considerable vibration and noise, and other objectionable features.

In order to avoid the objections above outlined. I have devised a pneumatic ogger that may be readily attached to the machine at any convenient `or suitable place, thus avoiding the necessity of a complicated system of levers for transmitting motion thereto.

My invention consists of a reciprocating air compressor, shown in section in Fig. Ll, directly connected by a suitable flexible hose to a cylinder having a piston reciprocable therein,shown in section in Fig. 3.

VThe `air compressor consists of a cylinder 1,

1926. serial No. 100,333.

having a piston 2 reciprocable therein, actuated by a connecting rod 3, which in turn is connected at 4 to a crank arm 5 which rotates in unison with a cog 6 of a conventional multigraph.

The cylinder 1 is connected by means ot any suitable lleXible tubing 7 to a cylinder 8 mounted upon suitable standards 9, while the tubing 7 is joined to the cylinder 8 by means of a tube 10. The same connection may be made by tapping into the inner end of the cylinder 8 and inserting a proper' connection, not shown but indicated as 11.

A face plate 12 is suitably connected to a trunk piston 13, of sufficient length to enable it to properly support the Weight of the face plate 12. The piston 13 is reciprocably fitted into the cylinder 8. i

It is evident that as the piston 2 reciprocates in the cylinder 1, air will be compressed and forced through the tubing 7 into the cylinder 8, thereby causing an outward movement of the face plate and piston 13. As the piston 2 is withdrawn by the crank-aim 5 from the cylinderl, a. vacuum will be created, which will cause the piston 13 to move inwardly, and thus a pulsating movement is established between the pistons 2 and 13.

Should the Vacuum be insuflicient to cause a certain and rapid return of the piston 13, this detect is cured by a light coiled spring 14, attached at one end to the standard 9a by a set screw 15, and at the other end is attached to the face plate 12 by a suitable fastener.

The tube 10 is held against longitudinal movement by the set screw 15. By means ot the said set screw, the face plate may be adjusted to any desired position to suit the size sheet to be printed.

The face plate 12 is limited in its reciprocable movement as shown by the dotted line 16 in Fig. 2.

A like stationary :tace plate 17 is disposed opposite and parallel with the face plate 12, so that the paper is neatly stacked against the face plate 17.

In Fig. 5 is shown a form of clamp which may be used to attach the Working cylinder 1 to the post or leg 18 of a multigraph stand or print-ing press.

rllhe clamp consists of two

semi-circular portions

19 and 20, provided with suitable ears to be clamped together by means of tap bolts 21.V One side of the clamp 19 is provided on one side with an ear 22 disposed at right- CII angles to the diameter of the clamp when closed. An identical clamp, with identical parts, is used to clamp the cylinder l and hold it against longitudinal motion.

Inasmuch as it is necessaryfor the cylinder l to oscillate when connected to the crank l, the two brackets shown in Fig. 5 are pivetally joined together by means of a tap bolt 23, holding the ears 22 ot' the brackets in pivotal connection with each other.

lt has been Yfound by experience that in operating my pneumatic jogger, that on starting the machine suddenly after it has been standing inoperative for a time, the piston requires several strolies to gain sulicient air to' canse the jogger to respond. To overcome this defect, a vent hole, not shown, is drilled through the cyliiuier at 2li, which permits su'llicient air to be drawn in on a single stroke of the piston to cau se the to respond with regular pulsating movements.
