TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Patented July 3, I91? Application and January 25, 1915. Serial No. 4,100.

To all whom it may concern:

Be it known that I, Gnonen P. KINGS- BURY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Typographical 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 U. S. Letters Patent, No. 436,532, to O. Mergenthaler, 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.

Ordinarily, these machines are equipped with a so-called font-distinguisher which is located in the clistributer box just in advance of the distributing mechanism proper and serves to prevent delivery thereto of matrices of improper font. In the use of such distinguis'her, however, the presence in the composed line of such a matrix is not detected until after the casting operation has been effected, with the result that the slug bears a type character of Wrong font and consequently must be discarded and a new slug cast in place thereof. This is not only annoying but occasions an unnecessary waste of time. In addition, in order to remove the ofi'ending matrix, the operator is compelled to leave his seat at the keyboard, and pass to the rear of the machine, where he will be within reach of the distributer box.

To overcome these various objections, I propose to locate the font-distinguisher at some point in advance of the casting mechanism, so that the presence of a foreign matrix may be detected before the casting takes place. Preferably, I mount the distinguisher on the assembler, wherein the line is composed, so that when the improper matrix is detected, it may be readily removed and without requiring the operator to leave his Seat at the keyboard I also p p to ploy an arrangement of some suitable character which will direct the attention of the operator to the presence of the improper matrix when it is detected. In one of the forms herein shown, I have provided looking means which, when a matrix of wrong font is present in the composed line, arrests the upward movement of the assembler and thus prevents the delivery of the line to the transfer devices which carry it forward for casting. In another form, I have provided an alarm which will be operated under similar conditions, as the elevator is raised. Other objects and the means for attaining them will later be described and finally pointed out in the claims.

In the accompanying drawings, I have shown my invention only in preferred form and by way of example, and as applied to a linotype machine, but obviously many changes and variations may be made therein, and in its mode of application, without de parture from its spirit. 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:

Fig. 8 illustrates a modification.

I have shown herein only such parts of a linotype machine as are concerned with my present invention. The other parts may be of the usual construction as embodied in the commercial linotype machine or as illustrated in the patent before mentioned.

The matrices X as they are released from their magazine pass onto the traveling belt A, which delivers them to the assembler B wherein they are composed side by side in line. The assembler is thereafter raised and leaf spring F on the elevator,

delivers the composed line to the carriage C, which transfers it endwise through the intermediate channel D for presentation to the mold, all as well understood in the art. The assembler B is provided as usual with two movable blades 1) and b, the latter arranged at the receiving end in position to arrest the descending matrices at their higher level, at which they are supported by the other blade b. The assembler is also provided with the customary swinging gate B, whereby access may be had to the line when desired.

According to my present invention, I provide the assembler B with a font-distinguisher which may cooperate with the matrices during or after composition and detect the presence of one of improper form or font. In the present instance, the distinguisher is in the form of a plate E extending throughout the length of the assembler and attached by means of a screw E to an overlying bar F, which latter is carried at its opposite ends by a pair of arms F pivoted, as at F, to the side members of the gate B. The arm F at the right has a downward extension F carrying at its lower end a roller F which tracks upon an inclined surface G formed on a bracket G attached to the framework of the machine. The other arm F of the bar F is provided with a roller F arranged in engagement with a the spring tending normally to move the bar F and the attached plate E inwardly toward the matrix line. However, the roller F on the downward extension F will engage the inclined surface G, when the assembler is in its lowermost or normal position and hold the plate E away from the matrix line, as indicated in Fig. 2. The effect of this arrangement is that the plate E will be moved toward and from the matrix line as the assembler is raised and lowered, respectively.

The matrices X of a given font are each provided in one of their vertical edges with two notches m, which notches are adapted to register horizontally when the matrices are composed in line. The purpose of the duplicate notches is to allow the matrices to be assembled at two different levels in the line, in which event the lower notches of the matrices at the upper level will register with the upper notches of the matrices at the lpwer level, as shown for example in Fig.

It is pointed out that the vertical position of the plate E is such that when moved inwardly by the rocking of the bar F itwill enter the alincd notches w of the matrices: It follows, therefore, that if there be present in the composed line a matrix without such notch, or one whose notch does not register with those ofthe other matrices (Fig. 3), the inward movement of the plate E will be arrested or prevented and the presence of the offending matrix thus detected.

I also provide means to arrest the upward movement of the assembler whenthe plate E is held against inward movement by an improper matrix. To this end, the extension F is formed with a laterally projecting lug F which is adapted to cooperate with a shoulder G on the bracket G, the lug F and shoulder G being so located as to stand in vertical alinement when the plate E is in its normal position away from the matrix line. As a result, if the plate E is maintained in this position, by reason of the presence of a foreign matrix, these parts will engage and arrest the assembler when it is attempted to raise it for the transfer of the line, as shown in Fig. 5. If, however, the matrices of the composed line are of the same font and in proper order, all their notches will aline and allow the plate E to be moved inwardly thereinto. In this event, the In F 5 will be moved out of register with t e shoulder G so as to clear it and allow the assembler to be raised in the regular way, (Fig. 4).

he general operation of the parts will be clear from the foregoing description, and it suffices to say at this point that the initial upward movement of the assembler will automatically effectthe movement of the plate E inwardly toward the composed line to detect a foreign matrix therein, and that the further movement of the assembler will depend upon the presence or absence of such a matrix. In this manner, the operator is advised as to the constitution of the line, and may proceed to correct it, if necessary.

In Fig. 8 I have shown, as an alternative construction, an alarm to indicate the presence of the improper matrix. In this figure, the lug F on the extension F is adapted to engage a spring-pressed arm H carrying at its outer end a striker H for a bell H According to this arrangement, when the plate E is held against inward movement by an ofiending matrix, the raising of the assembler causes the lug F to engage the arm H and move the striker H to active position, it being released when the lug passes the arm in the continued movement of the as sembler. The striker then sounds the alarm and notifies the operator.

It will be understood that different fonts of matrices Will be formed with diflerently located notches. I therefore mount the plate E so that it may be adjusted vertically to different positions to correspond to the location of the notches in the matrices of one font or another. In this connection, it will be noted that the screw E, previously referred to, passes upwardly through an opening in the bar F and is provided at its outer end with an adjustable nut E, which bears upon the upper face of the bar, and, as shown in Fig. 1, that the plate E is provided at its opposite ends with a pair of guiding studs E fitting in sockets in the bar F, the studs being surrounded by spiral'springs E which tend normally to urge the plate downward. It will be seen, therefore, that by turning the nut E in one direction or the other, the plate E may be raised or lowered to the desired position. An indicator I may be employed to assist the operator in effecting the proper adjustment of the plate.

In order that the spacers Y will not interfere with the detecting movement of the plate E, I form each of them with a cut or notch 3 of-a depth corresponding to that of the notches in the matrices and of an extent snfiicient to accommodate the plate in any of its difi'erent vertical positions.

As before pointed out, the bar F which carries the distinguisher plate E is connected to the swinging gate B. As a result of this arrangement, the gate and its connected parts are free to be swung downwardly in the usual Way to give access to the matrix line, as shown for example in dotted lines in Fig. 6. The customary spring F presses against the roller F 8 on one of the arms of the plate F and serves to hold the gate in its proper position,.just as heretofore.

As previously stated, I have shown my invention merely in preferred form and by way of example, and it will be obvious that many modifications and alterations therein will suggest themselves to those skilled in the art, and still be comprised within its scope.
