SHEET-REGISTERING DEVICE.

This invention relates to sheet registering mechanisms for Gordon printing presses and the like, and particularly to the mechanism employing a unitary reversible element mountable and operable to eifect the requisite registry movement of the sheet toward either the left or the right hand side of the printing press platen, as desired. A form of such mechanism is set out in Let ters Patent of the United States N o. 1,899,- 064, dated December 6, 1921, to which reference may be had.

The object of the present invention is to provide a registry device of novel construction which not only is positive and reliable in its operation, but possesses in a much higher degree than the patented device the merits of stability and durability.

To this end the invention comprises novel features of construction and combinations of parts which will be hereinafter described and claimed.

In the drawings Figure 1 is a plan of a platen, and adjuncts, equipped with a reversible sheet registering device embodying my present invention, said device being mounted to shift the sheet from right to left of the platen,

and the gripper bar being shown in down position.

Fig. 2 is a partial plan view similar to Fig. 1, but showing the gripper bar in raised position and the registering device shifted toward the left of the platen.

Fig. 3 is another partial plan view similar to Fig. 1, but showing the sheet registering device in reversed position to shift the sheet from left to right.

Fig. 1 is a longitudinal vertical section on the line l-4 of Fig. 2.

Fig. 5 is a similar section on the line 55 of Fig. 1.

Fig. 6 is a transverse vertical section on the line 66 of Fig. 2.

Referring to the drawings, 10 designates the platen of an ordinary Gordon press, and 11, 12 designate the end and side stops, respectively, for the sheets of paper imposed on the platen.

13 designates an oscillatory gripper bar mounted at one end of the platen, and 14 designates spaced-apart gripper fingers carried by said bar and adapted to be swung thereby at intervals upon and from the successive sheets on the platen, as usual.

Fast on the end of the platen, adjacent the gripper bar, is a bracket 15 upon which is adapted to be pivotally mounted an oscillatory lever comprising a bevel gear sector 16 and a tail portion 17. In the present in stance the tail portion is slotted to receive one end of the registering arm 18, and means, such as a set-screw 19, is provided to secure the arm fixedly yet detachably to the tail portion. The lever is adapted to be detachably and pivotally mounted on the bracket 15 by means such as a screw 20 screwed into a suitably located tapped hole 21 in the bracket, the lever being positioned with its tail portion projecting toward the right or the left hand side of the platen as occasion may require.

22 designates a double acting gear rack, which is detachably secured to the gripper bar by means such as a screw 23 entered in one or the other of two suitably-disposed screw holes 24. in thebar, so that the teeth of the gear sector mesh with one side or the other of the rack teeth according to the location, right or left, of the sector teeth. The rack teeth are formed on and transversely of the body of the rack and are of arcuate and angular contour in respect to the beveled teeth of the sector, as illustrated, so that the interlocking engagement of the respective teeth is constant irrespective of the up or down position of the gripper bar. Hence the sector, during the forward or active movement of the gripper bar and its rack toward the platen, is positively turned in a short are about its axis 20, and then in the back stroke of said bar the sector is returned to its original position.

When the rack member and the sector are mounted in either co-operative location on the gripper bar and bracket, provision is afforded for the effective right or left hand operation of the sector during the active movement of the gripper bar, as desired. In Figs. 1 and 4 the relative position of the rack and sector lever for left hand registration is shown, and in Figs. 3 and 5 their relative position for right hand registration is illustrated.

The registering arm, when it is secured to the tail piece of the detachably mounted sector lever as above described, overhangs the platen in a path between the end stops 11, and said arm thus partakes of the oscillatory motion imparted to the sector by the vibrating gear rack. The forwardend pf the arm 18 is provided with a spring clip 25 which is formed and arrangedto-grasp right or left handregistrati'on of the sheet on the platen.

The gri per bar and bracket maybe re spectively provided, similarly to the previously patentedconstruction, with additional screw holes so disposed that the sector lever and 'rack'can b'e "located at different.

relative positions in respect to the platen in order to operateupon-'sheets'of adifierent size or thickness, whether the device be positioned for either right hand or left hand registration.

I 0 not limit my invention to the detai'l's-otcbnstrhction herein. disclosed, as the same may be modified within the spiritot the invention and thescope of the appended claims.

'1. In a printing press'having a platen and sheet stops 'thereon'and having a vibratory gripper'bar co-operating with said-platen, a

sheet-registeringdevice comprising an oscillatory bevel gear member detachably supported adjacent the platen in eitherottwo oppositely-acting positions, j as desired, a

sheet-registering arm detachably secured to said'gear member and operable thereby, and a double acting gear rack carried by the I gripper-bar and adapted to be located thereon in engagement with the teeth of the oscillating gear menrb'erin either acting position of the latter, the teeth of s'aid gear rack being of arcuate and angular contour in respect to thebeveled teeth of the sec tor.
