TYPOGRAPHICAL Specification. of Letters intent.

PatentediSept. 14, 1915.

. v graphical 'Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States No. 436,532, to O. lliergenthaler, wherein circulating matrices are released from a magazine in the order in which their characters .are .to appear in print and .then assembled in line, the

composed line transferred to the face of a ,mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through distributing mechanism to the magazine from which they started. 7

More particularly, it relates to means comprising an automatic signal to indicate to the operator the presence of an'improper matrix in a circulating group thereof. In the present instance these means are illustrated in connection with the devices for delivering the matrices to the ,distributer, but they may alsobe employed for the same purpose in other locations, if it be desired.

In the accompanying drawings, I have shown my invention only in preferred forms and by way of example, and .as applied to a linotype machine. However, many changes and variations :may be made therein, and in its mode of application, which will still be comprised within its spirit. Similarly, it may be applied to other forms of typographical machines, such as typesetters, typecasters and the like, which handle type or dies, instead of matrices. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims.

Referring to the drawings: Figure 1 is a front elevation, partly broken away, of the distributor box, etc, of a linotype machine, with my improvements embodied therein; Fig. 2 is a somewhat similar view showing some of the parts in different position; Fig. 3 is a section on the line 3-3 of Fig. 1;

Fig. is a detail; and Figs. 5, 6, 7, and 8 are views illustrating various modifications.

Referring first to Figs. 1, 2, '3 and 4, the matrlces X are individually elevated and del vered by the lifting .device A to the screws 13 and distributer C, whereby they are restored to the proper channels in the magazine. Moreover, the matrices are each formed in their loweredges with notches X the location of which varies according to font, all in the manner understood in the art. These parts may be of any desired or approved construction, and in themselves constitute no part of my present invention.

Located in advance of the lifting device A lsthe font distinguisher or finger D, which normally projects upwardy into the path of the matrices and in registration with the notches 'X of the particular font in use, so that the matrices of this font are allowed to pass unimpeded to the lifting device. The d istinguisher or finger D is mounted upon the short rotatable shaft E, which is provided at its end with the button F and the grooves G, intended to be engaged by the pivoted latch (Figs. .3 and 4), this construction permitting the longitudinal adjustment of the shaft and the location of the finger in different positions according to font; The shaft E is located within the sleeve J, which is rotatably mounted in the frame, and is formed with a longitudinal slot through which the finger D projects, so as to insure the rotation of the sleeve with the shaft but still permit the longitudinal adjustment of the latter. (1onnected .to the sleeve is the projecting arm or striker K located in suitable position to ring the bell L mounted upon the frame.

The operation of the parts will be readily understood. When matrices of proper font are being delivered notches X finger D in D (Figs. 1 and 3), their register with and pass over the the usual manner, leaving it and the connected parts at rest. However, if an improper matrix, such for instance as one with a differently located notch, or one without a notch, or a reversed matrix, be presented to the finger (Fig. 2), the latter will be swung laterally together with the shaft E and sleeve J, and the striker K will be raised to active position. When this matrix is removed, as by the action of the lifting device A, the parts are free to resume their normal condition, and the striker rings the bell. In this Way the operator is notified of the presence of an ofi'ending matrix, and he may proceed to correct the difficulty. 7

Instead of an audible signal as above described, a visual one may be employed, as illustrated in Fig. 5. In this instance the signal takes the form of a disk M suspended bv the vertical shaft N and held normally by the spring 0 in an inconspicuous position, such as edgewise to the front of the machine. Mounted upon the sleeve J is the depending arm P engaging the end of an arm Q, upon the shaft N, so that when an improper matrix contacts with the distin- J guishing finger, the shaft N is rotated and the disk'swung to present its face to the operator, as shown by dotted lines, and thus indicate the presence of a Wrong matrix.

Fig. 6 illustrates a different form of audible signal, comprising the ratchet wheel It, the tensioned spring R connected thereto, and the striker R arranged to ring the bell B In this instance a pawl S is connected to the sleeve J andengages the ratchet It, so that when the distinguisher is moved, the pawl V is freed from the ratchet, and the alarm is sounded.

In Fig. 7 are illustrated electrical devices, comprising the normally broken circuit U connected with a battery or other source of energy U and an electric bell V. In this instance an arm T upon the sleeve J acts to close the circuit and ring the bell when the distinguisher is moved. Fig. 8 presents similar electrical devices connected to a visual signal, comprising the circuit Y, source of energy Y and concealed disk Z, which is moved into the view of the operator when the arm W on the sleeve J closes the circuit. 1

As previously stated, I have shown my invention only by way of example and in one or more preferred forms. Obviously, however, many modifications and alterations therein, and in its mode of adaptation, will suggest themselves to those skilled in the art, without departure from its scope.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:

1. In a typographical machine, the combination of distributing mechanism, a group Copies of this patent may be obtained for five cents each, by addressing-the of type or matrices movable through the machine for delivery thereto, and an automatic signal distinct from the distributing mechanism and adapted to be operated by an improper type or matrix in'the group.

2. In a typographical machine, the combination of distributing mechanism, a font distinguisher to control the delivery of type or matrices thereto, and an automatic signal distinct from the distributing mechanism and controlled by the font distinguisher.

3. In a typographical machine, the combination of distributing mechanism, a fontdis tinguisher adjustable to difierent operative positions to control thedelivery to the distributing mechanism of type or matrices of different forms or fonts, and an automatic signal distinct from the distributing mechanism and controlled by the font distinenter the notches therein; whereby the presence of an improperly notched matrix in the group'will engage said device and cause it to operate the signal.

5. In a typographical machine comprising type or matrices of diiferent forms, the.

combination of distributing mechanism, means for moving the type or matrlces through the machine for delivery to the distributing mechanism, an automatic signal distinct from the distributing mechanism, and an actuating device therefor arranged in the path of movementof thetype cr matrices and adapted to permit the passage of type or matrices of one form and adapted to be engaged by the passing type or matrices of another form so as to operate the signal. e

In testimony whereof, I have afiixed my signature in presence of two witnesses.
