LINOTYPE-MACHINE.

Specification of Letters Patent.

Patented Ca; 2, 19L6 Application filed September 12, 1905. Serial Nc 278,102.

To all whom, it may concern:

Be it known that LMELvIN W. MOREHOUSE, of Brooklyn, county of Kings, and State of New York, have invented anew and useful Improvement in Linotype-Machines, of which the following is a specification.

My invention relates to linotype-machines having the general organization represented in Letters Patent of the United States No. 436,532. In these machines circulating matrices are carried in a removable channeled magazine, from which they are released one at a time in the required order by escapement devices located at the lower ends of the channels and controlled by a finger-key mechan- 1sm.

Heretofore it has been customary to mount the escapement-levers and their pawls permanently in the lower end of the magazine, to

which the escapement-actuating springs were also attached in rear of the escapements, so that the escapements and attendant parts were necessarily removed from the machine with the magazine.

The present invention relates to a construction in which the magazine and the escapement mechanism formingacontinuation of the same are constructed as distinct members of the machine and independently supported, so that either may be removed independently of the other; also, that the one escapement mech anism may be employed in connection with a series of interchangeable magazines.

The invention consists in the arrangement and construction of parts directed to this end and to the exact alinement of the magazine and escapement mechanism, as hereinafter explained.

Referring to the accompanying drawings, Figure 1 is a side elevation showing the lower end of the magazine, the escapement mechanism, and the adjacent parts in operative positions. Fig. 2 is a similar view with the magazine removed, and Fig. 3 a similar view with both the magazine and escapement mechanism removed. Fig. 4: is alongitudinal vertical section from front to rear through the parts shown in Fig. 1; and Fig. 5, a perspective view, lookingat the lower left-hand cor ner, of the parts shown in the preceding figures.

In the drawings, A represents the rigid main frame, which may be of any form and construction, provided only it is adapted to support the operative parts hereinafter described.

B is an inclined base-frame for the magazine sustained by and forming,in effect, apart of the main frame and intended to remain ordinarily in a fixed position thereon. It may be varied at will, provided it is adapted to sustain the magazine and the upper end of the escapement mechanism, as hereinafter explained.

0 represents the inclined channeled magazine seated on top of the frame B, from which it may be lifted at will in order to be replaced by another containing matrices of a different font. It consists, as usual, of two parallel plates fixed to intermediate spacing-pieces and grooves or channels in their inner faces to receive and guide the edges of the matrices, as usual, although an equivalent construction may be adopted.

D represents the escapement -bar, so called, seated on the main frame and forming a continuation of the magazine. This bar is constructed with channels corresponding to those of the magazine, through which the matrices are delivered into the usual front plate E, containing vertical channels at which the matrices are directed to the usual assembling or composing mechanism. The escapement-bar D carries on its under side the escapements e, which consist of a centrally-pivoted lever having at opposite ends two pawls which are projected alternately upward into the lower side of the channels by the oscillation of the lever to permit the delivery of the matrices one at a time in a manner well understood in connection with the Mergenthaler linotype-machines of commerce. The escapement-levers c are seated, as usual, in slots in the under side of the escapement-bar and are moved in one direction by springs e and in the opposite direction by vertically-reciprocating reeds e ,urged constantly downward by springs 6 Fig. 1, of sufiicient strength to overcome the springs a, sothat the escapements stand normally in the position shownin Fig. 4, with the lower or forward pawl elevated. By means of the finger-key connections the reeds e are lifted and the spring 6' permitted to reverse the position of the escapement and to effect the release of the foremost matrix F. The general arrangement and action of the parts for actuating the escapement are the same as in the ordinary Mergenthaler machine with the following exception: Heretofore the actuating-springs have been located in the rear of the escapement-levers and the reeds eiwhich necessitated either the attachment of the springs to the magazine or the employmentofshort coiled springs,which were unsatisfactory in practice. To overcome these difliculties and at the same time admit of the escapement mechanism as a whole being independently supported and independently removed, I construct the escapement-bar D with a downward-extending flange Gr, located in front of the reeds e and their guide 6 To the lower edge of this bar D, I attach the lower coil ends of the springs e, which are extended upward and arranged to act on the forward face of an arm a, formed centrally on the escapement-lever e and extending downward therefrom, as shown. The form of the escapement-lever c, with its depending central arm 0 and the rear arm to engage the reeds c ,is original with me, as is also the formation of the spring-supporting flange or web on the lower side of the escapement-bar. This construction permits the use of long and flexible springs and admits of the entire escapement mechanism, comprising the escapementbar D and the escapement-levers and springs, to be constructed, assembled, sustained, and removed wholly independent of the magazine.

The escapement mechanism may be sustained on the main frame in any suitable manner; but I prefer to seat the upper edge of the escapement-bar D on the frame B adjacent to the lower end of the magazine, as shown at d. I As the bar and the magazine the channels of which must exactly coincide are thus sustained where they meet upon one and the same solid support, their exact alinement is insured. The lower or forward end of the bar D is preferably seated directly in the front portion of the main frame, as shown at d. The bar being thus supported at its upper and lower edges may be lifted from the machine at will without disturbing the magazine, and, on the other hand, the magazine may be removed at will without disturbing the escapement mechanism. The escapement-bar may be secured 'in place in any suitable rnanner-for example, by providing it, as shown in Figs. 1, 2, and 5, at each side with a downwardly-extending ear (Z through which a horizontal pin d is inserted into the main frame. The withdrawal of these pins will release the escapement mechanism, so that it may be lifted from the machine at will, the reeds 6 being first diconnected from the levers by swinging their guide 6 backward, as usual, around its pivot 6 In order to retain the matrices in the magazine when it is removed from the machine, I v

propose to employ any suitable means independent of the escapements such, for example, as the flattened rock-shaft shown in United States Patent to P. T. Dodge, No. 7 7 6,779, or the removable bar such as shown in the United States Patent to J. RRogers, No. 786,156, as shown at M, Fig. 4 of the drawings herewith. 'What I claim as my invention is 1. In a typographic machine, the combination of a main frame, a magazine'thereon, a channeled front plate fixed to the frame to receive the released matrices,'and an intermediate independently removable escapement-bar seated on the main frame and provided with escapements and with a depending flange carrying the escapement-spring.

2. In combination, the main frame, the magazine, the cooperating escapement mechanism independently removable, and means distinct from the escapement mechanism to retain the matrices when said mechanism is removed.

3. In combination, the main frame, the magazine seated thereon, and the escapementbar provided with the escapement mechanism and with the channels, forming continuations of those in the magazine, said bar being independently removable at will, substantially as described.

4:. The main frame provided with the magazine, the front channel-plate E and the reeds 0 in combination with the escapement-bar removably seated on the main frame and provided with the escapements and with the spring-sustaining flange (Jr extended downward between the reeds and the channel-plate, whereby the independent removal of the entire escapement mechanism is permitted.

5. In a linotype-machine, the main frame provided with the magazine and with bearings d and d, in combination with the detachable escapement-bar seated on said bear- 1ngs.

6. The escapement-bar channeled for the passage of the matrices and provided with depending flange G, in combination with the escapement-levers having depending arms 6, and the springs e secured to the flange and seated on the arms, substantially as shown.

. In testimony whereof I hereunto set my hand, this 6th day of September, 1905, in the presence of two attesting witnesses.
