TYPOGRAPI-IICAL MACHINE.
Specification. of Letters Patent.
Patented Sept.` 5, 1916.
Application mea september as, 1915. seriai No. 53,038.
To all whom it may concern:
Be it known that I, GEORGE 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 aspeciiication, 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 to O. Mergenthaler, No. 436,532, 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 returned through a distributing mechanism to the magazine from which they started.
More particularly, it relates to machines equipped with a plurality of magazines containing matrices of different font or face, any selected one of which may be brought into action at will. In one class of such machines, the magazines are arranged in fixed relation to an assembler entrance having throats or branches leading thereto, each magazine being provided with its own series of escapements to control the release of the matrices therefrom, and the several series of escapements being actuated by reeds which extend through the throats or across the ends of the magazines beneath,
thus requiring the matrices to pass between the. reeds as they are released from the lower magazines. This arrangement of the actuating reeds necessarily restricts the size or thickness of the matrices which can be used in the magazines, as the spaces between .adjoining reeds is limited and cannot be increased without altering the entire keyboard mechanism or the magazine construction.
My present invention is intended to avoid the above objections and aims to provide a construction wherein the matrices may be released from the several magazines without having to extend the escapement actuating reeds across any one of them, and thus to allow the use of matrices of any size which the magazines themselves are capable of handling. I secure thisA result, specifically, by operating the escapements of an'upper magazine by or through the medium of the matrices in an underlyingy magazine,.in a manner which will be fully described in the detailed description to follow and finally pointed out in the claims.
Referring to the drawings: Figure vl 1s a vertical section through the magazines and assembling mechanism of a linotype machine, having my invention applied thereto; Fig. 2 is a similar view showing the parts in different position; and Fig. Sais a section on the line 3 3 of Fig. 2.
The matrices X are stored according to font in the channeled magazines A, B, only two of which are shown herein, but of which a greater number might be employed if desired. These magazines are supported in the usual way upon the 'stationary base frames A1 and B1 and in constant-operative relation to the throats or branches C1 of the fixed assembler entrance C, through which the matrices pass to the assembler as they are released from the magazines.
The release of the matrices from the lower magazine B is controlled by' a series of escapements suitably supported in the base frame B1, and each comprising an angular pivoted lever D provided at its opposite ends with matrix-engaging pawls D1 and D2 which are projected alternately thereby into -the corresponding magazine channel. The rear pawl D2 is relatively short and is fixed to the rear arm of the lever D, while Athe front pawl D1 is considerably longer and is pivoted at its lower end to the forward arm of the lever so as to be slidable in guideways Da of 4the .supporting frame. Each-of the levers D is also provided with a depending arm D4 arranged in engagement with the hook-shaped end of thel rod FA suitably supported and guided in the machine frame by 'comb' plates F6 and con- Y with the forward end of the leading matrix in the magazine, being held Vin this position by the downward pressure of the rod F. When, however, the krod is raised by the actuation of the keyboard mechanism, the spring D5 withdraws the pawls D1 from the magazine to permit the escape of the leading matrix and simultaneously projects therearmost pawl D2 into the magazine to arrest the following matrix, after which the ese capement is restored to its former position by the return or downward'movement of the rod F, when the front pawl D1 is again pro jected into the magazine and the rear pawl D2 withdrawn therefrom, so that the following matrix which had been temporarily arrested by the latter will slide forwardly and be engaged by and come under control of the pawl D1.
The release of the matrices from the upper magazine A is controlled by a .series of escapements suitably supported in the base frame A1 and each comprising a. pivoted lever E provided at its opposite ends with matrix-engaging pawls E1 and E2, adapted to be projected thereby alternately into the corresponding magazine channel, and which are formed respectively with shoulders EG and E7 to limit the extent of their projection and of the rocking of the lever E in opposite directions. The pawls E1 and E2 are mounted to slide in guideways E1 of their supporting frame, the latter pawl E2 being pivoted at its lower end to the rocking lever E and the former pawl E1 being ,Y pivoted thereto between its ends, as at E5, and having its lower end extending into an opening B2 in the upper side plate of the lower magazine B. rlhe rocking of the levers E in one direction is effected by springs E5 bearing against the under sides of their rear arms, and their rocking in the opposite direction is controlled by the lowermost matrices in the magazine B which are shifted edgewise for that purpose in the manner now to be described.
In the present instance, the escapements of the lower magazine B are controlled in such manner that their forward pawls D1 may be given an excessive upward movement or overthrow to lift the leading matrices edgewise into engagement with the downwardly projecting ends of the escapement pawls E1, the upper side plate of the magazine B being cut away on its inner face, as at B3, to permit such angular .shifting of the matrices. Referring to Fig. 1, it will be noted that when the lower escapements are in their normal position, as shown therein, the shoulders F5 of the rods F are held slightly above or out of contact with the upper comb plate FG, this being due to the engagement of a cam piece H1 of a rook shaft or spindle H beneath the rear arms of the escapement levers D. When, however, the rock shaft is turned to disengage the cam piece H1 from the levers D, the bars F are immediately depressed by their springs F1, and carry with them the arms D4 of the levers D, thus causing the latter to project the forward pawls D1 upfarther into the magazine, as illustrated in Fig. 2, the extent of such projection being limited by the engagement of shoulders D3 on the pawls l tion the escapements for the upper magazine A stand in the position shown in the several figures, withtheir front pawls E1 in engagement with the leading matrices of the magazine, they being held in this position by means of a half-round rock shaft Gr, which prevents the action of the springs E5 tending constantly to withdraw them from the magazine to permit the escape of the contained matrices.
The operation of the parts is as follows: When the matrices are to be released from the lower magazine B, the parts should occupy the position shown in Fig. 1, that is, with the upper series of escapements held against action by the rook shaft Gr and with the cam piece H1 in engagement with the rear arms of the levers D of the lower escapements, which are thus caused to operate in their normal way to release the matrices from the lower magazine. If now it should be desired to deliver vmatrices from the upper magazine, the rock shaft H is irst turned to the position shown in Fig. '2, allowing the lowermost matrices in the magazine B to be shifted edgewise into engagement with the pawls E1 of the upper series of escapements in the manner before described, and then the rock shaft G is turned to the position shown in Fig. 2 to bring its recessed Vor cut away portion above the rear rocked by the springs E5. Such rocking, however, cannot take place immediately owing to the connection of the escapement levers E through the intermediate parts with the rods F, whose springs F1 are of sufficient strength to overcome the action of the springs E5. But when the rods F are raised by the operation of the keyboard mechanism, the springs E5 are allowed to act, withdrawing the forward pawls E1 from the upper magazine to permit the escape of the leading matrices therefrom and projecting the rear pawls E2 into the magazine so as to arrest the following matrices temporarily. As the pawls E1 are thus withdrawn, they shift the engaged matrices in the lower magazine downwardly to their original or normal position therein, causing the escapement pawls D1 of the other series of escapements to be depressed to a corresponding extent. Then when the rods F are subsequently pulled down by their springs F1, the escapement pawls D1 are again shifted upwardly to their abnormal position, lifting the matrices edgewise therewith and through their engagement with the forward pawls E1 projecting the latter back into the upper magazine A and withdrawing the rear pawls E2 therefrom, so that the previously arrested matrices in the magazine may advance and become engaged with the forward pawls to be released thereby upon the next operation of the escapements. In changing from one magazine to the other, therefore, it is merely necessary to move the rock shafts G and H either to locking or unlocking position, as the case may be. This movement of the shafts may be effected in any desired manner, either manually or by means of finger key mechanism.
From the foregoing, it will be seen that the matrices from the upper magazine are released by or through the matrices of the lower magazine, thus avoiding the use of reeds which extend across the latter for operating the escapements of the former, as has been the practice heretofore. Accordingly, there is no limitation imposed upon the size or thickness of the matrices which can be used in the lower magazine.
In order to prevent the liability of the pawls D]L being completely withdrawn from the lower magazine when its matrices are shifted downwardly by the escapement pawls El, the rock shaft H is provided with a second cam piece H2 which is so located thereon as to be moved above and across the rear arms ofthe escapement levers D when the cam piece H1 is disengaged therefrom to permit the delivery of matrices from the upper magazine, this relation of the parts being shown in Fig. 2.
As previously stated, I have shown myA invention merely in preferred form and by way of example, and it will be obvious that many changes and modifications may be made therein without departure from its scope. Thus, the particular form of escape- -ments may be different, or the shifting of the matrices effected by means other than the escapements, or the selection of the magazines otherwise controlled. lMany variations or alterations in these respects will readily suggest themselves to those skilled in ythe art.
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, the combination of a plurality of magazines containing matrices, and means acting through the matrices of one magazine to control the release of matrices from another.
2. In a typographical machine, the combination of a plurality of magazines containing matrices, and an escapement to control the release of the matrices from one magazine, the said escapement being operated by a matrix in another magazine.
3. In a typographical machine, the combination of a plurality of magazines containing matrices, an escapement to control the release of matrices from one magazine, the said escapement being operated by the edgewise shifting of a matrix in another magazine, and means for effecting such edgewise shifting of the matrix.
4. In a typographical machine, the combination of a plurality of magazines containing matrices, and an escapement to control the release of matrices from each of the said magazines, the escapement of one magazine acting through a matrix therein to operate the escapement of another magazine.
5. In atypographical machine, the combination of a plurality of magazines containing matrices, an escapement to control the release of matrices from each of the magazines, and means for causing the escapement of one magazine to shift a matrix therein edgewise to operate the escapement of another magazine.
6. In a typographical machine, the combination of a plurality of magazines containing matrices, an escapement for each magazine, the escapement of one magazine having a variable throw so as to act when operated either to release a matrix from the corresponding magazine or to shift said matrix edgewise to operate the escapement of another magazine, and means for controlling the throw of said escapement.
7. In a typographical machine, the combination of two magazines, an assembler entrance having throats or branches leading vwhereby said esoapements for the lower of actuating reeds connected to the escape- In testimony whereof, I have afIiXed my ments of the lower magazine, and means signature in presence of two Witnesses.
