TYPOGRAPHICAL MACHINE.

Specification of Letters lPatent.

Patented July 3, llQlW.

Application filed September 18, 1915. Serial No. 51,328.

To all whom it may concern:

Be it known that I, ALFRED W. F. Gnnsr, 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 has reference to typographical machines, such as linotype machines of the general organization represented in U. S. Letters Patent to O. Mergenthaler, No. 436532, wherein matrices representing the various characters to appear in print are stored in a channeled magazine and are re leased therefrom one at a time through the action of escapement devices controlleol by finger keys. In these machines, it is common to store the more frequently used characters, such as the letter e, in two or more channels of the magazine, and to provide mechanism whereby a single finger key may eifect their release from the different channels in alternation 0r succession. Such a mechanism is shown in the U. S. Letters Patent to D. S. Kennedy, No. 1,092,150, wherein the change from one channel to another is controlled by an automatic vibratory dog secured to the rear end of the finger key and which serves through intermediate parts to actuate the escapements of the duplicate channels in the required order.

My present invention follows somewhat along the lines of the Kennedy patent and aims to simplify and render more certain the action of the parts, to which end,'generally speaking, the vibratory dog is mounted upon a power-operated member controlled in its action by the finger key, as distinguishecl from attaching the dog directly to the key, as in the Kennedy patent. When thus arranged, the dog is controlled with greater certainty and allows the key to be operated bythe same light and rapid touch which characterizes the remaining keys of the keyboard. Another feature of the invention consists in arranging the automatic dog so that it may be rendered inactive at will to permit the release of matrices from one magazine channel continuously until a change to another is desired.

In the accompanying drawing, 1 have shown my invention merely in preferred form'and by way of example and as applied to the particular style of machine mentioned, but obviously many variations and alterations may be made therein and in its mode of application, which will. still be comprised within its spirit. Thus, it may be applied to other forms of escapements or matrix releasing devices, and to other styles of machines, such as typesetters, and the like. 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 drawing Figure l is a detached perspective view, partly in section, of the escapement actuating mechanism of a linotype machine having my invention applied thereto;

' Figs. 2 and 3 are detached detail-views showing the parts in different relative positions;

Fig. 4 is asection on the line 44 of Fig. 2; and 1 Fig. 5 is a section on the line 55 of Fig. 4.

The matrices X are stored in the channeled magazine A and are released therefrom by the escapements B, one for each channel of the magazine, and which are actuated by the vertical reeds C, the two outermostones (which alone are concerned with the present invention) being designated C and C These escapement reeds are operated by the yokes D, (only one of which is shown herein) provided with the lifting cams or eccentrics D adapted to be thrown into engagement with the constantly rotating roller 1) by the yoke sustaining dogs E, when the latter are tripped by the vertical slides F upon the actuation of the finger keys G. The parts so far described are of the usual construction and may be found in U. S. Letters Patent to P. T. Dodge, No. 530,931. The single cam yoke D shown herein is controlled by a finger key bearing the letter e and serves through parts, presently to be described, to actuate one or the other of the reeds C and G to release matrices having the same character from the two outermost magazine channels.

In the present instance, and according to my invention, the alternate action of the reeds C and G is efiected through the me dium of a vertical longitudinally-movable member K arranged above the cam yoke D in position to be actuated thereby, and suitably supported and guided in a fixed bracket J, which also gives support to the reeds C and C The member K is provided at its rear edge with a vibratory dog H arranged in a recess K and mounted upon a pivot stud K so as to be brought into engaging relation to one or the other of the reeds C and C The dog is of the same construction as disclosed in the Kennedy Letters Patent before referred to, being formed with a transverse slot H through which the stud K passes, and provided with shoulders H and H on opposite sides of the slot, and having pointed ends H and H the former being arranged to cooperate with an oppositely pointed or inverted V-shaped block M With the parts thus constructed and arra ed, when the key G is depressed, the yoe D is raised by the engagement of its cam D with the constantly driven roller D and shifts the member K upwardly. This upward movement of the member K is communicated to one or the other of the reeds C and C through the engagement therewith of the corresponding shoulder H or H of the dog H, and during such movement the lower end H of the dog slides along one or the other of the beveled faces of the V- shaped block M until the member K is lifted to its full extent, when the dog is rocked and shifted bodily toward the right or left as the case may be to locate its pointed end on which then, during the return movement of the member K, brings the other shoulder of the dog in engaging relation to the cone spending reed. The particular mode of action of the dog is fully explained in the Kennedy patent, to which reference may be had, if desired, for any further description.

The present arrangement differs from that of Kennedy in the respect that the automatic dog is located upon the longitudinally movable member K instead of upon the finger key, asa result of which the dog is controlled positively under the influence of the power-operated cam yoke D, thus insuring greater certainty and uniformity in its action andwithout affecting the usual sensitive touch of the key. For instance, the relatively prolonged actuation of the member K allows greater time for the lateral shifting of the dog, and the upward shifting of the member-to the same extent at each actuation also insures the lifting of the dog the required distance for its proper cooperation with the block M In order to avoid the automatic shifting of the dog H, so that it may be caused to actuate only one of the escapement reeds C and C under repeated actuations of the finger key, the block M is carriedby a slide M so as to be movable instantly thereby to an inactive position when desired. The movement of the slide is effected by an eccentric M engaging in a recess in its rear face and fast upon a short shaft M exposed at the front of the machine, and provided with an operating handle 1. whose turning in one direction or the other shifts the block M into active or inactive position, where it is held by spring fingers M engaging in recesses in a roller M on the shaft (see Figs. 4 and 5). In Figs; 2 and 3 the block M is shown in inactive position, causing the dog H to operate as follows: As

illustrated in Fig. 2, tl1e dog stands with its shoulder H in engaging relation to the reed C and with its pointed end H located to the left of the V-shaped block M so that when the dog is raised-by the upward movement of the member K, itspointed end slides along the bevel at the left of the block, the dog in the meantime turning about its pivot K to the position indicated in Fig. 3. When the member K completes its upward movement, the lower end of the dog stands above the pointed end ofthe block Mfiand normally these parts would overlap so as to cause the dog to slide down the bevel at the right of the block, but owing to the altered position of the block M the lower end-of thedog cannot overlap it, as indicated by dotted lines in Fig. 2, so that when the dog is lowered by the return of the member K, it slides down the same beveled surface along which it was raised and is the opposite beveled face of the block M thereby shifted back to its original position.

.As a result, the dog is caused to actuate the reed C each time the finger keyis operated. The effect of this arrangement is that the automatic mechanism which controls the clelivery of the matrices from alternate magazine channels is rendered active or inactive at will. One of the advantages of the ar-, rangement is the capability of interchanging magazines in different machines,that is, it allows the use of a magazine without an extra channel for duplicate matrices in a machine equipped with the present or similar automatic shifting-arrangement.

As previously stated, I have shown my invention merely in preferred form and by way of example, and obviously many changes and-modifications therein will suggest themselves to those skilled in the art without departure from-its scope.

Having thus described myinvention, its

her, and a finger key controlling the action of said mechanism.

2. In a typographical machine, the combination of two independently operable reeds, a reciprocating member provided with an oscillating dog movable into engaging relation to the reeds alternately, means for reversing the position of the dog at each operation of said member, powerdriven mechanism for operating the memreeds.

5. In a typographical machine, the combination of the reeds C and C the longitudinally-movable member K provided with the slotted dog I-I having the shoulders H and H and the pointed end H and the pointed block M cooperating with the pointed end of the dog, in the manner and for the purpose described.

6. In a typographical machine, the combination of means for effecting the delivcry of matrices from a channeled magazine, automatic mechanism for controlling said means to cause the delivery of matrices alternately from different channels of the magazine in a definite and predetermined order, and means whereby the said automatic mechanism may be rendered inactive at will.

7. In a typographical machine, the combination of two actuating devices, a single finger key, automatic mechanism for causing the key to operate said devices alternately in a definite and predetermined order, and means whereby said mechanism may be rendered inactive at will so as to allow the finger key to operate a selected one of the actuating devices alone at successive actuations.

8. In a typographical machine, the combination of two reeds, a reciprocating membei provided with a vibratory dog to engage and actuate the reeds alternately, automatic mechanism for controlling the action of said dog, and means whereby said meclzhanism may be rendered inactive at Wil 9. In a typographical machine, the combination of the two reeds C and C the actuating member K provided with the dog H, the block I 1 controlling the action of the dog, and the movable slide M carrying the block M In testimony whereof, I have aflixed my signature.
