LlNOTYPE-MACHINE.

SPECIFICATION forming part of Letters Patent-No. 548,432, dated October 22, 1895.

application filed January 8, 1394.. Serial No. 496,056. CNo model.)

To aZZ whom it may concern:

Be it known that I, PHILIP T. DODGE, of Washington, in the District of Columbia, have invented a new and useful Improvementin 5 Linotype-Machines, of which the following is a specification.

My invention has reference more particularly to linotype-machines of the Morgenthaler class, in which a finger-key mechanism I is used to select and assemble in line a series of matrices stored in a magazine, the assembled line being presented to a mold into which type-metal is delivered, so as to form in the mold a slug or linotype, bearing on its front I edge in relief the characters represented by the line of matrices, the matrices after the casting operation being distributed and returned to the top of the magazine, from which they are again delivered at the foot in a new order or arrangement for the production of succeeding linotypes.

In practice it is frequently desirable to change the style or face of the type characters produced.

The aim of the present invention is to permit a more speedy and convenient change of face without the necessity of removing either the matrices or the magazine; and to this end it consists, broadly, in combining with the distributing and the delivering or assembling mechanisms a multiple magazine-that is to say, a magazine adapted to contain two or more-fonts or sets of matrices-provision being made for adjusting or changing the rela- 3 5 tion between this magazine and the distributing and composing mechanisms, so that one set of matrices or another may be brought into action at will.

In the accompanying drawings I have rep- 0 resented my improvement as intended more particularly for use in the Mergenthaler machine of the form represented in Letters Patent of the United States issued on the 16th day of September, 1890, No. 436,532.

The distributing mechanism is constructed and fixed in position at the top of the machine, as shown. The escapement devices and their connections, by which the selected matrices are assembled in line, are also constructed as heretofore and fixed in position at the lower end of the magazine.

The magazine, instead of being permanently connected at the upper end with the entrances from the distributor and at the lower end with the escapement devices, is made separate therefrom and arranged in such manner that it may be raised and lowered bodily. It is composed of two or more sections, each similar to the ordinary magazine, lying one above another and each adapted, preferably, to contain a complete font or set of matrices.

Adjusting devices are so connected with this magazine that it may be raised or lowered in order to bring either of its sections at will into communication with the distributor at the top and with the escapement or delivery mechanism at the foot. In this way the matrices may be delivered into and out of either section of the magazine at will without duplicating the distributing or composing devices.

The accompanying drawings represent only such portions of the machine as are necessary for an understanding of my invention. In all other respects the machine may be of the same construction as that shown in the Lotters Patent above referred to, or of any other equivalent construction, the invention consisting, broadly, in the combination, with distributing and composing mechanisms, of an intermediate magazine containing two or more sets or series of matrices, with provision for changing the relation of this magazine to the other mechanisms, so that either set of matrices may be brought into action, as demanded.

In the drawings, Figure l is a vertical crosssection in a fore-and-aft direction through the magazine, the distributor, and the delivery devices of a Mergenthaler machine containin g my invention, the magazine being elevated so that its lower section is in use. Fig.

2 is a similar view, showing the magazine lowered to deliver matrices from the upper section. Fig. 3 is a cross-section on the line 3 3. 5

Referring to the accompanying drawings, A represents the rigid frame of the machine, which may be of any form adapted to sustain the other parts.

B represents the distributer-bar, extending roo horizontally across the upper end of the magazine and having longitudinal permuted teeth to engage corresponding teeth in the upper ends of the matrices C in such manner that as the matrices are moved along the bar they are held in suspension thereby until they arrive over the appropriate channels D, into which they will fall and through which they slide into the appropriate channels in the magazine E.

The magazine consists of parallel metal plates arranged in pairs, having their inner or approximate faces provided with longitudinal grooves e to receive and guide the edges of the matrices, which slide downward therethrough one after another, each groove or channel being devoted to matrices bearing the same letter. In this instance the magazine consists of two pairs of plates, or, in other words, of two ordinary magazines, one directly over the other, the two being connected firmly together, so that they may be raised and lowered as one. Each of these magazine-sections is adapted to receive matrices at the upper end, hold them in storage, and deliver them at the lowerend inthe or dinary manner, and as regards the number and arrangement of their channels the two sections are alike.

The magazine, as a whole, is sustained by devices which admit of its being raised and lowered bodily, so as to bring the channels of its upper or its lower section into communication with the passages D from thedistributer. I

As herein shown, the support consists of two transverse rock-shafts F, each having crank-shafts f, connected by links f to the side of the magazine-frame. The rock-shafts are also provided with depending arms f connectedby a rodf passing through a handnutf journaled in the main frame, so that by turning this nut the magazine may becarried upward'or downward.

At the lower end of the magazine there is a stationary mouthpiece G, having channels corresponding with those in the magazine-sections through which the released matrices pass to the assembling devices below. This, mouthpiece is provided for each channel, with an escapement device H, consisting of a con trally-pivoted lever or verge having pins which project upward alternately through the bottom of the magazine. These escapement-levers receive motion through rods I from fingerkeys representing the various characters, as in the ordinary machine.

The action is as follows: Assume, for illustration, that the upper section of the magazine contains nonpareil matrices and the lower section minion matrices. If the hand-screw be turned to raise the magazine to the posi tion shown in Fig. 1, the minion matrices will be delivered from the lower section of the magazine past the escapement H to the composing mechanism, and thence to the line, after which they pursue the ordinary course through the machine and the distributer, by which they are returned to the section from which they were delivered. If, on the other hand, a nonpareil face is demanded in print, the magazine is lowered to position shown in Fig. 2, thus bringing the upper section into connection with the distributing and dis charging devices, so that the nonpareil matric'es will be passed through the machine in precisely the same manner that the minion matrices were previously handled.

It will of course be understood that the matrices of one font or face are distributed before the magazine is shifted to bring those of another font into use.

It is to be understood that the magazine may be provided with three, four, or more sections and that the means for effecting the adjustment may be varied at will within the range of mechanical skill.

In order to insure alignment of the channels, I prefer to provide at the top and hot 5 tom' stationary stops K, to limit the adjustment of the magazine, and to provide the rod on opposite sides of the arms f with springs f so that by giving an over motion to the rod the magazine may be crowded upward or downward with a yielding pressure against the stops.

WVhen onesection of the magazine is in use, it is necessary to prevent the escape of the matrices from the other section. This may be effected by providing on the frame stationa y uard-plates L to cover the lower end of the magazine and prevent the escape of the matrices as it is carried upward and downward. As an additional precaution,the lower end of the magazine may be provided with transverse holes M, through which a bar or rod N may be thrust, as shown in Fig. 2.

While I have described my improvement in connection With machines using matrices or female dies, it is to be understood that it is also applicable, generally, in machines in which punches or male dies are used for the purpose of producing matrix impressions in papier-ma'ch, lead, or other material from which to cast the linotypes as a separate operation.

Having thus described my invention, what I claim i s- 1.
