TYPOGRAPHICAL MACHINE.

Application filed December 4, 1916.

To all whom it may concern:

Be it known that I, Gnonon P. KINGsBURY, 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 ac companying' 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. 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 elevated and returned through distributing mechanism to the magazine from which they started.

More particularly, it relates to that class of machines equipped with a plurality of magazines which are movably arranged so that any selected one thereof may be brought into operative relation to the assembling and distributing devices. Ordinarily, the magazines are disposed in the machine at an inclination of about forty-five degrees, and are movable in a straight path at right angles to their plane of inclination; and to insure their movement in this manner, it has been the practice to make use of suitable guiding devices in addition to the shifting mechanism by which they are raised and lowered.

My present invention is intended to avoid the use of such guiding devices and contemplates the provision of shifting mechanism of such character as will maintain or guide the magazines in a perfectly straight path during their movements without the aid of any further or additional devices.

In the accompanying drawings, I have shown my invention 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 which will still be comprised within its spirit. Thus, the details thereof may be Widely varied, and it Specification of Letters Patent.

Serial No. 134,823.

may be adapted 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 l is a side elevation of a portion of a linotype machine having my invention applied thereto;

Fig. 2 is a similar in different position;

Fig. 3 is a section on the line 33 of Fig. 2; and

ig. i is a top plan view with the magazines removed.

The matrices are stored according to font in the magazines A, B and C, which are carried by the shift frame D. The lower magazine C rests directly upon the frame D, while the magazines A and B are mounted upon their customary base frames A and B which are pivotally connected at their upper ends, as at A and B to up standing projections D of the shift frame and which rest at their lower ends upon the underlying magazines. The shift frame D is mounted in the supporting frame E and is arranged to be moved toward and from the same to bring one or another of the magazines into operative relation to the as sembler entrance G and the channel entrance F which latter is pivoted to the machine frame, as at F and arranged in position to receive the matrices as they are released from the distributing mechaninsm F. The supporting frame E is sustained at its lower end upon a pair of adjusting screws E and at its upper end upon a transverse rod 131', being provided at opposite sides with set screws E bearing against the rod. The screws E and E may thus be used to locate the supporting frame in or adjust it to its proper position in the machine frame.

As previously stated, my present invention relates chiefly to the mechanism for shifting the magazines, and it contemplates the provision of such mechanism as will effoot the raising and low ring of the magazines in a perfectly straight path without the aid or use of additional guiding devices. In the present instance, such mechanism is view showin the parts of the parts mounted. in the supporting frame E so as to retain all the advantages which exist in such construction, for example, the capability of adaptation to existing machines, without material change therein, the easy assemblage of the parts, etc.; but if preferred, it may be mounted directly in the machine frame. In carrying out my invention, I preferably employ two rotary peripheral cams H, arranged at opposite sides of the magazines and cooperating with rollers D journaled in arms projecting clownwardly from the forward end of the magazine shift frame D (see particularly Fig. 3). The cams H are fast upon a transverse rock shaft H mounted to turn. in bearings at the front end of the supporting frame E, and provided with an operating handle H The extent: of the cams is such as to efiect a change from the uppermost to the lowermost magazine, or vice versa, the rollers D resting on the lowest points of the cams when the upper magazine is in operative position (Fig. 1), and on their highest points when the lowermost magazine is in such position (Fig. 2). lVhen the middle magazine is in operative position, the rollers rest in depressions H formed at corresponding points in the cams. The cams are thus constructed to register and hold the magazines in proper position when in use or operation, but if desired other mechanism of any of'the well known forms may be employed for this purpose.

In addition to the cams H, I employ a system of toggles or jointed links H, H and H each a replica of the other, to take part in the shifting of the magazines. These parts are duplicated at opposite sides of the magazines, and the description of one of them will therefore suffice. The jointed links or members H and H face in opposite directions and are both loosely mounted at their lower ends upon the cam shaft H and connected at their upper ends to a common pivot stud H projecting from the magazine frame D at the front. The link or toggle H faces in the same direction as the link H and is pivoted respectively to the rear end of the magazine frame D, as at H", and to the supporting frame E, as at H The links H and H are connected together by means of a longitudinal rod H attached at its opposite ends to their respective joints. The third link or member G is provided at its joint and between its upper and lower sections with a roller H arranged in contact with a flange or track portion H formed on the lower edge of the connecting link H.

The operation of the parts will now be clear: when the cams H are rotated to shift the magazines upwardly, the jointed link H due to its connection with the magazine shift frame D, is lengthened out, and the longitudinal connecting rod H is moved to the rear to efiect a corresponding elongation of the rear linkor toggle H which thus raises the rear ends of the magazines to an extent equal to that of their forward ends; and the lowering of the magazines of course effects the reverse operation of the parts. And the tendency of the magazines to slide forwardly (due to their inclination) isresisted and overcomeby the cooperation of the roller H3 of the jointed link H with the track H of the connecting rod H As thus constructed, the 'magazine shifting mechanism will and can only move the magazines upwardly and downwardly in a straight path thus eliminating any necessity for the use of supplemental guiding devices, etc. To facilitate the raising of the magazines, I have also provided a counterbalancing spring H which is of the torsional variety and surrounds the cam shaft H having one end fastened to one of the cams and its other end connected to a projection E of the supporting frame E.

As previously stated, I have shown my invention merely in preferred form and by way of example, and it is obvious that many modifications and alterations therein, and in its mode of application, will suggest themselves to those skilled in the art without departure from its scope. Thus, the cams H may be arranged to cooperate with one of the other parts instead of directly with the magazines; or, if desired, the .cams may be replaced by some other shifting device or entirely eliminated and the link or toggle system alone relied upon to effect the raising and lowering of the magazines.

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, nation of a plurality of magazines, and mechanism for shifting them to bring one or another into operative position, the said mechanism including means incorporated therein to maintain the magazines in a straight or rectilinear path during their movement, thus avoiding the use of supplemental guiding devices. 7
