JOHN BURGER, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO THE MERGENTHALER LINOTYPE COMPANY.
MACHINE.
SPECIFICATION forming part of Letters Patent No. 554,770, dated February 18, 1896.
Application filed April 12, 1893.
To all whom, it may concern.-
Be it known that I, JOHN BURGER, a citizen of the United States, and a resident of Providence, Rhode Island, have invented certain new and useful Improvements in Linotype-Machines, of which the following is a specification.
There are now known in the art, in different forms, machines designed to cast printing slugs or bars, each bearing on one edge the type characters to print an entire line or number of words, these slugs beingknown as linotypes.
In all successful machines now in use the linotypes are cast from type-metal delivered at suitable intervals into a mold the front of which is closed by a line of temporarily assembled or composed matrices, representing individual characters, these matrices serving to produce the type characters in relief on the edge of the bar or linotype cast against them, as illustrated, for example, in Letters Patent of the United States issued to Ottmar Mergenthaler on the 28th day of February, 1888, No. 378,798, on the 8th day ofApril, 1890, No. 425,140, and on the 16th day of September, 1890, Nos. 436,531 and 436,532, to which reference may be had for detail explanation of their construction and operation.
In order to insure the perfect action of these machines it is necessary that the temporary line of matrices and intervening spaces shall be presented accurately and closely against the face of the mold during the casting operation, in order that it may close the mold throughout its length to prevent leakage of the molten metal past or between the matrices.
The present invention has in view the stoppage of the casting action, while the remaining mechanisms are permitted to continue their action.
$erlal No. 470,011. (No model.)
justed in front of the mold, so that if the line is not properly presented and locked up against the mold the stop device will be caused to prevent the action of the casting mechanism, and this although the assembling and distributing mechanisms and other parts of the machine are permitted to continue their several actions.
In the preferred embodiment of my invention, illustrated in the accompanying drawings, the improvement includes a stop device engaging directly to prevent the action of the pump by which the metal is delivered to the mold, and stop-controlling devices which are in their turn controlled by the matrix-adjusting devices.
In the drawings I have representedmy invention applied to that form of machine represented in Letters Patent Nos. 378,798 and 425,140 above mentioned, and reference may be had to said patents for a detailed description of such parts as are not shown herein, the present drawings being limited to those portions of the machine which are necessary to an understanding of my invention.
Referring to the drawings, Figure 1 is a perspective view of the casting mechanism and adjacent parts with my stop devices arranged in connection therewith. Fig. 2 is a sectional elevation from front to rear through the same parts. Fig. 3 is a detailed view showing the dog in engagement with the pumpplunger. Fig. 4 is a vertical cross-section through the upper part of the 1noldwheel, matrix-supporting yoke, and adjacent parts.
In the drawings, A represents a portion of the main frame; J the mold-wheel in the form of a vertical circular disk, having the slot or mold proper, in which the linotype is cast, out therethrough from one face to the other, as shown in Fig. 4, so that the molten metal admitted from the rear may fall against the matrices at the front.
K is the melting-pot heated by a gas-flame and containing a supply of molten type-metal, which is delivered therefrom at suitable intervals by the action of the pump-plunger K, the pot being provided with a delivery spout or mouth, which, during the casting action, fits against and closes the rear side of i'he mold into which it discharges.
Iis a rising and falling yoke or carrier into which the assembled line of matrices and spaces is delivered and by which it is lowered to a position in front of the mold J and there sustained, so that the characters or matrices proper of the entire line are presented to the face of the mold, as shown in Fig. 4:, so that the linotype may be cast against them. The matrix-line is confined at the ends between and limited in length by the j awsj andj mounted in a stationary part of the frame in front of the mold.
The yoke I is sustained and guided at the front by the main frame in such manner that when the yoke is lowered to its extreme position it will present the matrices between the jaws and against the face of the mold, against which they should be tightly confined during the casting action, these parts being con structed and arranged to operate in the same manner as the parts bearing like letters in Letters Patent No. 35,140.
Referring now to the parts which form the subject of my invention, Z represents an angular dog or stop connected by a horizontal pivot .2 to a fixed standard .2, the lower end of this dog being of suitable form to engage in the notch 5" in the pump-plunger in such position as .to hold the plunger in an elevated position and prevent it from falling, so that the delivery of metal to the mold is thus rendered impossible. The plunger may be raised by cam connections or other positively-acting devices and depressed by a spring, as in the patent mentioned, so that the dog acts only to prevent the action of the depressingsprin g and plunger. The dog is actuated by a lever pivoted to a standard 5 on the frame and carried downward at the front of the machine, and there provided with a projection .2 in the path of a pin or projection on the matrix-supporting yoke or elevator I. The vertieal action of this yoke or slide, which is mechanically actuated, as usual, serves to automatically control the stop and thereby the action of the casting mechanism without aifeeting the operation of the remainder of the machine.
\Vhen the elevator adjusts the matrix-line properly in front of and against the mold, the projection .2 causes the lever to hold the dog Z out of action, so that the pump and other parts are free to act in a normal manner and cast a linotype in the mold against the matrices. If, hOWOX'Ol, the matrix-adjusting devices fail to assume their proper positionsthat is, if they present the matrices in improper relation to the 1noldthey will fail to actuate the lever .2 and the dog or stop Z will be permitted to remain in engagement with the pump-plunger, as shown in Fig. 3, and thus prevent the action of the pump.
Thus it will be seen that the casting operation is made dependent upon the proper adj ustment of the matrices, and the pump automatically independently stopped it the mat rices are not properly presented to the mold. The projection .2 is secured to the trip-lever by an adjusting-screw, as shown, so that its position may be adjusted with extreme aceuracy.
It is manifest that the form and arrangement of the parts may be greatly modified to adapt them to different machines and to meet special requirements in different cases.
I believe myself to be the first to combine with a linotype-maehi'ne means for inde pen dently stopping the action of the casting devices, and the first to combine with casting devices and a stop mechanism therefor means for automatically controlling the action of the stop devices.
It is to be observed that my dog or stop device automatically engages to prevent the motion of the pump-plunger each time that the latter is raised, so that the elevated plunger is normally in a locked condition, and that the unlocking of the plunger auto1natically or otherwise is necessary before the cast ing action can occur.
Having thus described my invention, what I claim is- 1. I11 a linotype-maehine and in combination with its casting mechanism, a stop device to prevent the action of the eastingmechanism without preventing the action of the other parts of the machine.
2. In a linotype-machine and in combination with its pump i'ordeliveringmetal to the mold, a stop device which automatieall y locks the pump independently out of action when the plunger is raised.
3. In a linotypc-machine the combination of the pump-plunger and a stop device which automatically engages said plunger when raised.
4:. In a linotype-machine and in combination with its casting mechanism, a stop device, controlled by the matrixadjusting mechanism and directly engaging the casting mechanism, to hold it independently out of action.
5. In a linotype-machine, the combination of a mold and pump to supply the same with molten metal, matrices to close the mold, matrix-adj usting devices and a nunpqilungerraising device, independently connected with the matrix-adjusting devices, whereby the pump may be stopped, without stopping the remainder of the machine.
