PRINTERS BRASS-RULE CORNER.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed September 22, 1905. Serial No. 279,742.

To all whom it may concern:

Be it known that we, HENRY O. BARTH, GEORGE H. RIEJIL, and WERNER IIONEG GER, citizens of the United States of America, and residents of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvmnents in Printers Brass-Rule Corners, of which the following is a specification.

The object of our invention is a corner for a printers brass-rule, which will allow type to be set close against it, will form a close and straight fit with the rule and in the face of which a number of grooves may be formed. This object is attained by the means illustrated in the accompanying drawings, in which,

Figure 1 is a perspective view of a corner for a printefs rule, embodying our invention. Fig. 2 is a similar view of a blank before it has been milled out to form the corner shown in Fig. 1. Fig. 3 is a top plan view of the corner shown in Fig. 1. Fig. 4 is a horizontal sectional view taken through the corner and a part of the brass-rule. Fig. 5 is a plan view of a part of the frame, a printers rule with our corners at the ends thereof and a number of type and printers furniture holding the same in place.

Referring to the parts: The body of the corner is formed of two wings, a, a, the sides of each wing of which are parallel to each other and meet the surfaces of the other wing at right angles forming an internal and an external right angle (1 (1 The face, A, of the corner registers evenly with the end of the wing, a, at a", over-hangs the angle, a at a and registers with the end of the wing, a, at a. In the face of quadrant, A, a number of concentric grooves, a may be formed. The wings, a, a, are made of a width equal to that of the body of the rule, B, with which the corner is to be used. To form the corner embodying our invention, we take a rectangular prism, A of brass, form the face, A, in one end thereof by cutting down the corners, leaving the corner, a, in its completed form. We then cut the grooves, a, in the face, A; then we mill off the corner, a diametrically opposite the corner, 0. to form the wings, a, a, the right angle, (1 and the over-hanging face, a

In use the corners are placed with the ends of the faces, a'*, or a, registering with the ends of the rule, 13, with which it is to be used, the external right angled surface of the corners bearing against the type, or printers furniture, C, such as shown in Fig. 5. Then quadrats, or type, D, are placed in the angle, (1 and against the inner surface of the body of the corner and against the rule, B. By reason of the face, A, overhanging the angle, a*, it is seen that the type may be set close up to the corner and thus the printed matter may be brought close to the corner of the outline. The type, or quadrats fit firmly against the angle, a, hold the corner straight with the rule B, and enable a close fit to be made between the faces of the rule and the corner, so that in prirfting with this corner no break will appear in the outline.

The firm fit between the printers furniture, C, upon one side of the corners and the rule, B, and of the type and quadrats within the angle, (1 and against the other side of the rule, B, hold the corners in accurate alinement with the rule, 13, so that grooves, a formed in the face, A, will have their ends registering with similar grooves, b, formed in the face of the rule, so that in printing, no perceptible break will occur between the lines in the rule and the lines in the corners.

What I claim is:

A printer's corner the body of which consists of two wings of equal width meetingeach other 'at right angles and the face of which consists of a quadrant of a circle the ends of which register with the ends of the wings and in the face of which are cut a series of concentric grooves.
