SPECIFICATION forming part of Letters Patent No. 594,053, dated November 23, 1897.

Application filed May 28,1892. Serial No. 434,804. (No model.) i

To all 1071 0711, it may concern:

Be it known that I, HENRY A. WISE Woon, a citizen of theUnited States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Registering Mechanisms for Printing-Presses, ofwhich the following is a specification.

The aim of this invention is to produce a new and improved registering mechanism for printing-presses which will secure absolute and perfect register between the impressioncylinder and the reciprocating bed of a printing-press and to use this registering mechanism for other purposes, as hereinafter described.

The invention is especially designed and adapted for use in connection with the two or multi revolution single or multi cylinder printing-press,though of course the same may be adopted and used with any form of print-' ing-press, and with this 'understandingl will further describe my invention as applied to the ordinary well-known two-revolution single-cylinder printing-press.

My invention consists of the device described and claimed in this specification and ating nut.

illustrated in the accompanying drawings, in which a Figure 1 is a side elevation of enough of a two-revolution single-cylinder printing-press to illustrate my invention. Fig. 2 is a central sectional view of the same from the rear. Fig. 3 is a section on line 3 3 of Fig. 2 of the clutch-operating mechanism. tion' on line 4 4 of Fig. 3 of the clutch-actu- Figs. 5 and 6 are a side elevation and plan, respectively, of the clutch-operating screw; and Fig. 7 is a longitudinal sectional view illustrating the position and arrangement of the inking mechanism.

Referring to the drawings and in detail, A represents the usual framing of a printingpress, in which are journaled in the usual manner the eccentric bushings B, in which is journaled the shaft 0, and on this shaft 0 is mounted or formed the impression-cylinder D, which impression-cylinder is continuously driven in the same direction by suitable gearing, as gear F.

Mounted loosely on the shaft 0, so as to turn Fig. 4 is a secindependent of the impression-cylinder D, is the registeringgear E. This registeringgear E is undercut, as at e, to form one member of a friction-clutch, as shown. The other member of this friction-clutch consists of atapered sleeve G, which is keyed on the shaft 0, soas to turn therewith and so as to be capable of a sliding or lateral movement on said shaft. The member G has a projecting hub g, in which is cut a groove g. It will be seen that when the friction-clutch formed by the gear E and sleeve G is locked the cylinderand registering-gear will be locked and turned together, but when the friction-clutch is not in engagement the cylinder D and gear E are independent of each other.

On the end of the shaft 0 is mounted the usual driving-gear F.

' H designates the usual reciprocating bed, and on this bed is mounted .the registeringrack I. This registering-rack I extends the whole length of the bed, so that gear E and rack I are always in mesh, and the mesh of the teeth of these instrumentalities is much more than the vertical movement of the shaft 0 and impression-cylinder D, whereby as the bed reciprocates back and forth the gear E will be oscillated.

Mounted on the side of the impression-cyl- 8o inder, inside of the gear E, is the startersegment K,which cooperates with the starterrack J, mounted on the bed. This starter mechanism is important and is necessary to the device, because the friction-clutch cannot always be thrown in to engage in the same place; but by using a starter segment and rack to first start the bed and cylinder inregister and then throwing the friction-clutch into engagement the bed H and cylinder D 0 will always be geared together at the same point to secure absolute register.

Adapted to engage the groove g of the tapered sleeve G is the nut L. This nut L is preferably made in two pieces and bolted to- 5 gether, as shown in Fig. 3, andthe same has a projecting lip I, that is adapted to engage groove g, whereby the nut L and sleeve G will be laterally locked together, but so that the nut L can remain stationary and the disk I00 G revolve. Also, it will be seen by referring to Fig. 2 that the lip Z has considerable play vertically in the groove 9, so that the tapered disk or sleeve G can rise or fall without moving the nut L up or down, as nut L and disk G are only held rigidly together laterally.

On the inside of the nut L is formed a thread L of comparatively steep pitch, and the nut L has a projecting arm L, by which the same is oscillated, as hereinafter described.

Bolted to the inside of the framing is the cooperating screw M, which has a screwthread m, adapted to engage the internal thread L of the nut L. The screw M has a flange M, by which the same is held to the frame A, and in this flange are formed a number of circumferential slots m, and passing through these slots are the bolts M whereby the screw M is rigidly held to the framing, but whereby the same can be adjusted circumferentially to get a proper action of the friction-clutch.

Connected to the arm L is the link M the bottom of which is formed into a yoke P, that engages the square block 12. Mounted on the shaft Vand attached to this yoke are the rollers 10 and 11, that bear on the sides of the cam Q, which is fastened to the shaft V. The shaftVis rotated once for each complete excursion of the bed or two revolutions of cylinder D, and the shaftVmay be driven from gear F by means of gear R, pinion S, intermediate l, and gear U, and this gearing is so designed that the reduction in the same is two to one.

The eccentric bushings are operated in the usual manner from the oscillating shaft X, on which are mounted rocker-arms V, which connect by links "0 to the arms b of the eccentric bushings B.

The gear E oscillates synchronously with the reciprocating bed, and the same is well adapted and may be used to drive an inking mechanism placed at either side of the impression-cylinder.

In the drawings (see especially Figs. 1 and 7) it will be seen that an inking device is placed to the rear of the impression-cylinder and under the feed-board and is driven from said oscillating registering-gear E. This specific inking mechanism consists of the drum or distributing-cylinder 61, on the shaft of which is mounted the gear 50, which meshes with said registeringgear E, whereby the drum-cylinder will be oscillated. Cooperating with this drum-cylinder are the inkingrollers 62, 63, and 51; The rollers 62 and 63 maybe mounted, if desired, in the side frames and the roller 51 mounted in the swinging arms 52. The roller 51 engages the distributing-roller 53, which distributing-roller 53 engages with and conveys ink to the formrollers 54 and 55, mounted in the usual manner, to deposit the ink on the forms of the bed,and a suitable ink-fountain (i8 is mounted as shown, and ink is carried from the fountain-roller 69 of the same by ductor-roller 65 and deposited upon the inking-roller 53. This ductor-roller 65 is mounted in the usual manner in the arms 66, which are mounted on shaft 67, and shaft 67 is oscillated in any of the usual well-known manners not necessary here to show.

The drum-cylinder 61 and the distributingroller 53 may be vibrated positively in any of the well-known manners not necessary here to show. Thus it will be seen that the inking mechanism is nicely driven from the registering-gear before described, so that the form-rollers will always turn in a direction to properly coact with the bed.

The operation of my device is apparent and is as follows: As shown in the figures, the bed is just commencing its forward or printing stroke and the impression-cylinder has just been lowered to engage and coact with the bed. Now as the cylinder turns the starter-segment K will-engage the rack J and bring the cylinder and bed in perfect register. Then when the segment and rack are fully in mesh the cam Q will raise the rod M oscillate the nut L on the screw M, and force the tapered disk G into engagement with the gear E, and thus lock the gear E to the shaft C. Now when the bed completes its forward stroke the cylinders will be raised, and as the bed commences its retrograde stroke the gear E will turn in an opposite direction from the cylinder D, the gear E and rack I being always in mesh; but just about the time the movement of the bed is reversed the rod N is lowered, thus oscillating the collar L, withdrawing the friction-disk G, and disconnecting the gear E from the cylindershaft. It will be seen that the starter-segment starts the cylinder in proper action and then that the friction-clutch will keep the bed and cylinder in register during the forward or printing stroke of the bed. Thus this mechanism will impart to the bed aperfect register, and the mechanism will act very smoothly and nicely, as there are no striking parts or take-ups. Also it will be seen that the inking mechanism will be correctly and nicely driven by means of the oscillating registering-gear, as before described.

The details and arrangements of parts herein described may be greatly varied by a skilled mechanic without departing from the scope of my invention as expressed in the claims.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
