TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Patented Jan. 16, 1917.

Application filed February 24, 1915. Serial No. 10,215.

To all whom it may concern Be it known that I, DAVID S. KENNEDY, 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 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; and its chief object is to provide an improved form of mechanism for effecting this movement of the magazines, as will be more fully described in the detailed description to follow, and finally pointed out in the claims.

In the accompanying drawings, I have shown my invention in preferred form and by way of example, and as applied to a linetype 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 may be adapted to other forms of typographical machines, such as typesetters, type-casters 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 side elevation of a portion of a linotype machine having my invention applied thereto; Fig. 2 is a similar view showing the parts in different position; Fig. 3 is a top plan view of the magazine supporting frame; Fig. 4i is a section on the line 4ll of Fig. 1; Fig. 5 is a section on the line 5-5 of Fig. 1; and Figs. 6, 7 and 8 are detail vlews.

The matrices X 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 respectively, which are pivotally connected at their upper ends, as at A and B to upstanding 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 so as to be movable toward and from the same to bring one or another of the magazines into operative relation to the assembler entrance G and the channel entrance F, which latter is pivoted to the supporting frame E, as at F and arranged in position to receive the matrices X as they are released from the distributing mechanism F. The parts so far described are or may be substantially similar to those disclosed in my previous Letters Patent No. 1,104,512, dated July 21, 1914.

The shift frame D is provided at its forward end with a downwardly projecting plate D slidably engaged in a groove 01' guideway E in the supporting frame E; and at its rear end the frame D is provided with rollers D journaled upon the upstanding arms D and traveling upon tracks E rising from the supporting frame. In this way, the frame D is held in position upon the supporting frame E and is properly guided in its shifting movements. The supporting frame E rests at its lower end upon adjusting screws E and at its upper end is pivotally mounted upon a pair of supporting studs E projecting from the framework (see particularly Fig. 5).

As previously stated, my present invention relates chiefly to the means for shifting the magazines, and its principal aim is to provide a mechanism which is simple in construction, strong and durable in character, highly eflicient in operation, and inexpensive in manufacture. I also propose to which exist in such construction, for example, the capability of adaptation to ex1st ing machines without material change therein, the easy assemblage of the parts, etc. In carrying out my invention, I employ four rotary cams H, one arranged at each corner of the magazines, and cooperating with rollers D journaled in arms projecting downwardly from the shift frame D, '(see particularly Figs. at and The forward pair of cams H is fast upon a transverse rock shaftH mounted to turn in bearings at the front end of the supporting frame E, while the other pair of cams is fast upon a transverse rock shaft H mounted to turn in bear ings at the rear end of the supporting frame.

7 The two shafts are connected by a fore-andaft shaft H which is provided at its opposite ends with bevel gears H meshing into complementary bevel gears H fixed to the two shafts H and H (see Fig. 3). By this construction, the two pairs of cams are caused to rotate in unison so as to shift the magazines to equal extents at their opposite ends. Surrounding the shaft H is a powerful torsional spring H? fixed at one end thereto and at its opposite end to the frame E, and tending to rotate the cam system to raise the magazines and thus to counterbalance their weight.

It will be noted that each of the cams lis formed with two fiat surfaces or steps H upon which the rollers D rest when one or another of the two lower magazines is in operative position, Fig. 2 showing 'by full lines the steps at the shorter radii of the cams in engagement with the rollers, and by dotted lines the steps at the longer radii in engagement therewith. lVhen the upper magazine is in operative position, the shift frame D rests upon and is supported by the frame E, as shown in Figs. 1 and 5. In order to prevent the overthrow of the cams at the end of their full range of movement, one of each pair is provided with a lateral. projecting lug it which is adapted to engage the supporting frame E at such time.

The operation of the cam system is effected by a handle J (see particularly Fig. 7 fixed to one end of a stub shaft J journaled in the supporting frame E, and which is provided at its opposite end with a small gear J meshing into a larger gear K fast upon one end of a shaft K. Similarly the shaft K is provided with a small gear K meshing into a larger gear H on the end of the shaft H of the cam system. This arrangement not only enables the operator to shift the magazines uniformly and with little effort, but the gears are so proportioned as to allow the operating handle to 5 occupy the same position after its operation irrespective of the magazine selected, which feature is important in effecting the proper cooperation of the handle with locking mechanism now to be described.

The handle J (see Fig. 7) is provided with a spring-pressed grip M having a de tent M which is adapted to engage in a recess N of a locking plate N mounted in a block l\ fixed to the'side of the supporting frame E. The block N is formed with a beveled cut N to engage the detent M and push it outwardly as the handle is rotated so that it may snap automatically into the recess N when it comes into alinement therewith, and the plate N is formed with a projecting shoulder N to engage the detent at such time to prevent overthrow of the handle, and thus serve as a locating and registering means therefor. In order to insure that a selected magazine be in proper position, when the handle J is released by the attendant, I construct the locking mechanism so that the handle cannot be engaged therewith at any other time. To this end, the locking plate N (see particularly Figs. 6 and 7 is slidably arranged in the block N and is connected to an arm N fixed to one end of a short shaft N which carries at its other end a spring-pressed arm N tending normally to shift the locking-plate N rearwardly, so that its recess N will stand out of alinement with the detent M of the grip M. To control this tendency, I

provide the shift frame D with a downwardly extending arm 0 formed with cam projections 0 which are adapted to engage a laterally projecting lug N on the arm N and cause the latter to shift the locking plate N back to its active position. There are as many such cam projections O as there are magazines in the frame, and they are so located that theywill actuate the arm N only when one or another of the magazines is brought into operative position. As a result of this construction, if the operator fails to complete the operation of the handle J, it cannot'be locked in place (see Fig. 7 but if he does complete its operation, the locking plate N is shifted to its active position and the detent M will be arrested by the projecting shoulder N and allowed to snap automatically into the notch N and thus lock the parts against movement (see Figs. 2 and 6). It may be noted that two complete rotations of the handle J are required to effect a change from one maga zine to the next one, so that unless the operator completes both these rotations the locking plate l 2 will remain in inactive position and the handle cannot be engaged in its recess.

Referring to Fig. 8, it will be noted that the back plate of the assembler entrance is connected to the usual supporting frame P by an intermediate bracket P ,'which not; only serves as a convenient means of attachment, but also as a reinforcing device for the assembler entrance.

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.
