1 Claim.

The present invention relates to thegeneral class of typeca-sting machines and automatic typesetting mech-ines of the teletypesetter class, and more specifically to an improved matrix guide or attachment employed with the matrix receiver or assembler elevator, and gate, to engage displaced matrices and seat them in correct position in the line of type.

The primary object of the invention is the provision of a guiding device located in the matrix receiver or assembler elevator of the Linotype machine, in position to intercept and engage unseated matrices as they are fed from the star wheel in usual manner and properly seat the displaced matrices on the rail or supporting shelf in correct position. The guiding means is located within the receiver or assembler elevator in the path of a displaced matrice after it passes through and leaves the elevator gate, in lieu of aligning the matrices before they enter the ate according to existing mechanisms.

For this purpose the guiding device of my invention is an attachment constructed, arranged, and combined with the line receiver or assembler elevator in such manner as to insure required freedom of movement of the properly placed matrices in order of composition; and at the same time provide a somewhat funnel shaped or restricted path of movement within the receiver which guides or forces displaced or unseated matrices into correct position in the line.

The invention consists essentiall in certain novel features of construction in the attachment, and combinations and arrangements of the attachments in the line receiver or assembler elevator of a type composing machine as will hereinafter be described, and more specifically set forth in the appended claim.

In the accompanying drawings I have illustrated one complete example of a physical embodiment of my invention wherein the guide is combined and arranged in accord with one mode I have devised for the practical application of the principles of my invention; but it will be understood that changes and alterations are contemplated and may be made in these exemplifying drawings and mechanical structures within the scope of my claim, without departing from the principles of the invention.

Figure 1 is a view in front elevation of so much of a typesetting machine as is necessary for an understanding of my invention, showing a portion of the assembler elevator or matrix receiver or a conventional automatic Linotype machine,

to which the guideof my invention is atta'ched at the right handside of the assemblergate.

Figure '2 r is aerear' elevation of the right hand side of the receiver or assembler elevator.

Figure 3 is a vertical transverse sectional view at line 3-3 showing a matrix and the guide in the receiver.

Figure 4 is a horizontal or top plan view, partly in section, showing the guide in the receiver or assembler elevator; and

Figure 5 is a detail perspective view of the angular attachment or guide, detached.

In the drawings, in order that the relation of parts may be understood, the assembler elevator or frame F is bolted at G to the Linotype machine, and the gate H is pivoted at I on the upper portion of the frame, with the upper rail assembly mounted on the upper part of the gate H. The actuating bar L is operated by the manual lever N through the horizontal shaft 0 and arms P, P.

As disclosed in Fig. 5 the angular bracket forming the matrix guide includes a metallic attaching plate I having a slot 2 for one or two screws 3, by means of which the guide is affixed on the inner face of the right-hand arm 4 of the assembler gate H, preferably employing existing holes in the arm intended for the usual fender attachment.

The angular, beveled, or curved plate 5 of the guide is located in position to project into the receiver or assembler elevator with the corner C extending approximately .063! farther into the receiver than the corner D; point B is located .080" farther into the receiver than point C; and point A is approximately .082" farther in the receiver than point D. Preferably the plate 5 of the L-shaped bracket or guide is longer along its bottom edge than its upper edge, and the free outer edge of the plate is obliquely arranged with relation to the substantially top and bottom parallel edges.

The matrix M is delivered or fed by the star wheel to the receiver, and in the event the matrix fails to properly seat itself in the receiver, the next following matrix pushes against the displaced matrix causing it to contact or engage the plate 5 of the guide. This contact and engagement forces the unseated matrix upwardly and over the rail hook or shelf R until the matrix reaches the left end of the guide. As the matrix passes the end of the guide, the matrix, by gravity, is automatically seated within the receiver in proper alinement with the correctly seated matrices in the line. I

When a matrix correctly seats itself the toe a perfect assembly in the course of composition;

without interruption of the process.

Having thus fully described my invention,

What I claim as new and desire to secure by Letters Patent is:

In a Linotype machine having an assembly elevator gate, a matrix guide therefor for guiding matrices into the gate comprising a substantially L-shaped member having an attaching plate portion and an angular plate portion, an elongated slot in said attaching plate portion,

a screw in said slot and adapted to threadedly engage the gate whereby said attaching plate may be adjustably secured to the same, said angular plate portion lying in a plane intersecting the plane of said attaching plate portion along a line forming an acute angle with the longitudinal axis of said slot, said angular plate having a free end lying in a plane extending at an angle to the plane of said attaching plate portion, whereby an inclined guiding surface extends at an angle to the path of movement of the matrices into the gate.
