REGISTERING DEVICE FOR PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 300,225, dated June 10, 1884.

Application filed August 23, 1883. (No model.)

To all whom it may concern:

Be it known that I, J our: H. CRANSTON, a citizen of the United States, residing at Norwich, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in Registering Devices for Printing-Presses; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to registering devices for printing-presses; and it consists in the construction and arrangement of mechanism for adjusting the pins used as side guides, as hereinafter more fully described and claimed.

In the annexed drawings, illustrating the invention, Figure 1 is a perspective view representing a portion of the lower end of the feed-board, which is provided with a hinged section or leaf, having a transversely-sliding extensi on that carries the registering mechanism. Fig. 2 is a similar view showing thehinged portion or leaf of the feed-board elevated. Fig. 3 is a perspective view illustrat ing a modification. Fig. dis a plan of the adjusting mechanism shown in Fig. 1. Fig. 5is a plan of the mechanism shown in Fig. 3. Figs. 6 and 7 are bottom plan views of another modification. Fig. 8 is a section on the line aa: of Fig. '7. Fig. 9 is a section on the line y of Fig. 6. Figs. 10 and 11 are bottom plan views of a further modification. Fig. 12 is a section on line 2 z of Fig. 10.

Like letters of reference designate like parts in the several views.

A in Figs. 1, 2, and 3 represents a portion of the lower end of the feed-board of a cylinder printing-press. To the lower end of this board A is attached a hinged leaf, B, that supports the registering mechanism. The hinged section or leaf B may have a transversely-- sliding extension or guide piece, 0, connected thereto by a tongue and groove, as shown in Figs. 1, 2, 4, 6, 7, 8, and 9; or it-may be re cessed for the reception of a guide-bar, D, as shown in Figs. 3, 5, 10, 11, and 12.

In the'guide-piecc C, Fig. 1, or the guide bar D, Fig. 3, as the case may be, are formed holes a a. for the reception of a pin, 2), that serves as a side guide for securing an accurate side register. any hole at a greater or less distance from the edge of the feed-board, as required, thereby approximating its proper position; and, in order to secure an absolutely perfect adjust ment, the guide-piece G or guide-bar D is moved transversely by means of an adj ustingscrew, E, that turns in bearings c (1, one of which is secured to the leaf B and the other to the guide-piece O or guide-bar D, as the case may be. It will be seen that by turning the screw E slightly the attendant can adj ust the relative position of the guide-pin 1) without leaving his proper place at the side of the press or without reaching over the press. The under side of the guide-piece G is beveled, as shown in Figs. 1 and 2, to approximate the curve of the cylinder, or as shown in Fig. 3, where the guidebar D is substituted for the sliding guide-piece O, the lower edge of the leaf B will be beveled in a similar manner.

At the junction of the leaf B and sliding guide-piece C, on the under side, is a rod, F, supported in bearings e f, as shown in Fig. 2, or bearings of g, as shown in Figs. 6 and 7, the bearings f f on the guide-piece 0 being so arrangedas to slide on the rod F in adjusting the register-pin. The rod F supports springtongues G G, Figs. 1 and 2, that are curved, as shown, to correspond with the curve of the cylinder, and serve as rests for the ordinary front guides. (Not shown.) These tongues are each provided with a box or eye, It, through which the rod F passes, the tongues being thus capable of adjustment upon the rod; to

the required position with relation to the front guides of the press, their frictional contact with the under side of the leaf being sufficient to 'hold them in place.

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

1. The combination, in a cylinder'printingpress, of a feed-board, A, having a hinged leaf, B, an adjustable support, having a series of holes, a a, for the reception of a vertical guide-pin, I), and a screw, E, for adjusting the guide-support, substantially as described.

The pin 21 may be placed in 2.
