STATS ATEN FRANCIS H. RICHARDS, OF HARTFORD, CONNECTICUT, ASSIGNOR, BY MESNE ASSIGNMENTS, TO AMERICAN TYPOGRAPHIC CORPORATION, A CORPORATION OF NEW JERSEY-- MECHANISM FOR MAKING- TYPES.

Specification of Letters Patent.

Patented April 28, 190s.

Original application led July 29, 1899, Serial No. 725,456. Divided and. this application :filed June 19, 1900.

Serial No. 20,814.

To all whom it may concern:

Be it known that I, FRANCIS H. RICH- ARDS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Mechanism for Making Types, of which the following is a specification.

This invention relates to mechanism for making types, and more especially for making these types on the edges of typebars or linotypes.

The present application is a division of that filed by me July 29, 1899, Serial No. 725,456.

In the drawings accompanying this specification and forming part of the present application, Figure l is a side elevation, partly in section, of an improved mechanism for making types in accordance with my present invention. Fig. 2 is an end elevation of the apparatus as seen from the left hand in Fig. l. Fig. 3 is an enlarged view illustrating the mode of operation of the apparatus and the manner of practicing the invention. Fig. 4 is a view looking toward the right in Fig. 3. Fig. 5 is a view similar to Fig. 3 but showing the typebar in section and an advance step in the operation of forming a type and Fig. 6 is a side view thereof.

Similar characters designate like parts in the different figures of the drawings.

In accordance with my present improvements each type may be formed on the edge of a type body or typebar, and when the types to be made are formed on the edge of a typebar, successive portions of the edge of the typebar are respectively subjected to the operation of type-forming dies or matrices, which dies or matrices, by means of some suitable apparatus for carrying and operating the same, are brought to bear one after another in any order desired upon the edge of the typebar. For the purpose of holdingthe typebar in position when the types thereon are to be formed in a machine., the-bar is held by a support 2, which preferably consists of a guide or carrier. The bar is fed along in the machine by some suitable mechanism. The several dies (herein designated without choice by the reference character 3) are supported or mounted in such a manner that they may be brought to and moved from the working point in the machine. One manner of so mounting the dies is illustrated in the drawings. According to this particular organization of the mechanism, said dies are carried in a revolving carrier 4L, each die being shown providedvwith a spring which operates to normally hold the die in a retracted position, the spring bearing against the head 5 on the top of the die.

The die-carrier 4 is shown fixed on the lower end of the carrier-shaft 6, which shaft is to be rotated to bring any required die into position for use. For this purpose, and to properly control the operation of the diecarrier, said carrier-shaft is shown provided with a stop-wheel 7, which wheel is furnished with a series of stops either in the form of perforations, as shown in the present case, or it may be of pins instead of perforations, thus following an ordinary mode of making stopcylinders. For operating in connection with the cylinder-stops a series of stop-pins (designated without choice by the character 8) are shown mounted in an upright 9 of the framework of the machine, which upright may also carry a bearing l0 for the carriershaft.

The carrier-shaft 6 is shown mounted in the bearing 12, which bearing in the particular form of apparatus herein illustrated eX- tends downwardly from the top-plate 30 of the chamber or oven A within which the carrier and the dies or matrices carried thereby are shown inclosed. Said oven is for the purpose of keeping the dies at the proper temperature, and for this purpose a current of air or other gas or fluid may be circulated through the chamber A by means of the inletpipe 13 and the discharge-pipe 14, the air or gas being supplied from a furnace and the current being maintained by suitable blast apparatus. (Not shown.) For this purpose an ordinary air-pump or a rotary blower may be employed. The oven is shown as provided with a lining 50 of refractory material for conserving the heat of the oven and preventing radiation from the outer surface of its walls. The die-carrier having been revolved to the proper position to bring the selected die to the working point in the machine, the corresponding stop-pin, as 8, will be brought into engagement with the corresponding cylinder-stop, as 7, and the die or matrix will be forced down throughits working stroke and thus (or otherwise) broughtinto forcible contact with the type-body or typebar, as the case may be, for making the type thereon. In practice this operation may be carried out in either one of several ways. According to one way, the die or matrix may be forced down to a fixed position, and afterward the type body or bar be forced up wardly against the die or matrix through the working stroke required for finishing the type, According to another plan, the stroke of the die or matrix will be continued downwardly against the typebar sufficiently far to complete the forming of the type; this mode of operation is shownin this case. For so operating the die, I have shown the V'apparatus provided with a dieactuating slide 15, which slide or pusher may be conveniently operated by means of a hand-lever 16, shown pivotally supported at 17 on the framework of the machine, being connected by a link 18 with the upper end of said slide.

In the apparatus here-described the bar is shown mounted in the carrier 2, and this is connected by an electric conductor 2() to ay source of electrical current, indicated at B, from which another conductor 21 leads to the die mechanism, so that on the operation of the die to form a type an electric heating current is made to ilow through the die or matrix and that portion of the bar subjected to the action of the die, thus heating and softening the metal which is being acted u on by the die. The die, when this is heate in the oven or chamber, is thereby prevented from so readily chilling the metal of the type, and at the same time a less quantity of the electric current will be required. One character having been formed, as set forth, the handlever 16 is raised, thereby lifting the plunger 15 and preferably cutting off the electric current. rIhis is accomplished by connecting the conductor 21 to the slide 15, but in some cases the current may be carried through the conductor-shaft, it being immaterial to some features of my present invention how the current is supplied. to the type-forming die. On returning the die-actuating blade, this, by means of a pawl 22 or like, device, operates the ratchet wheel 23 for feeding forward the typebar ready for the next type-forming o eration. For the purpose of controlling t e electric current, one portion of the parts inserted should be insulated from the rest so as to direct the current through the metal being operated upon by the die. For this purpose I prefer to insulate the carrier 2 in which the type body or bar is directly supported. The insulating material employed in this instance is shown at 24, Fig. 2.

indicated at 4', Fig. 2, the parts being sepa- The die-carrier 4 may be formed in two parts, as

rated by insulating material 25, and similarly the die-actuating plunger may be operated through` a tubular non-conducting guide 26.

The means for making and breaking the electrical circuit may consist of the type-die or matrix and type body or blank in connec'- tion with any suitable appliances or means for operating these one toward and from the other. In this case the circuit is made by the contact of the die or matrix with the metal when beginning the type-forming operation; and, vice versa, the circuit' is broken by the withdrawalof the die from the ty e. But by employing a separate circuit ma rer and breaker at some other point in the electrical circuit the advantage is obtained of being able to hold the type-forming die in contact with the type for a longer period than would otherwise (in some cases) be practicable.

In some cases my invention will be employed without the electric current, in which case the dies should be heated to a temperature about equal to or a little less than the melting point of the type-metal. When the electric current is employed in connection with the means for maintaining the dies normally in a heated condition, the electric current coperates with the previously heated die in forming the type. In some cases, however, the dies may be used cold, except as they are heated during the use of the die by the heating current passing between the type metal and the die. In connection with this feature of my present improvements reference is made to another application Serial No. 167,947, reiiled August 1, 1903, originally iiled July 29, 1899.

One means for supplying heat to the metal being operated upon bythe die consists in the die-stem or shank through which the heat will be conducted to the metal from the interior of the oven or heating chamber .in which the dies are carried. The major portion of the stem of the active die will for this purpose remain in the oven during the die action.
