Serial No. 587 88?! bllti higher level, be-

positively operating faces of the supporting ledge and matrices being beveled according to the direction in which this leveling takes place or the wringing impulse is applied.

".lhe invention is not limited in respect oi its constructional details. lilecause these are vz zriablc to any extentso long as the posh tivrlv ell'ected edgewise swing secured.

.i-unong the possible embodiments of the invention the following three have been chosen for illustration In the accompanying drawings 1-F igures -l to 3. are vertical sections illustrating one embodiment oi the invention; Figs. 4 and 5, are verliral sections illustrating a second embodiincnt; and Fig. (l is a vertical section illuslrali a third embodiment.

lle'l erl to i l: l to 3, l is the first elevator; one of the matrices in the higher or normal position; 3, their supporting ledge fast to the elevator i 4, one of the matrices in the lower or variant position; 5, the mold against which the said elevator 1 is holding the composed line, and both therefore, in the casting position; (3, a bar or matrix lifter in a cavity in the elevator 1 and held by a lover T tulrrnmed at 8 in said cavity, under the adjacent top lugs S) of the matrices 4, the opposit 1 arm 10 of the said lever projecting beyond the front oi" said elevator; 11, a stop adjustable in tho frame 12 of the machine and standing in the path taken by the arm 10 as the elevator 1 moves from the casting position to meet the second elevator; 13, a spring to return the bar (3 to its normal position: 14-, a bevel or cam on the bottom edge.

edge 3; and 15, a bevel upon each of of the l the cooperating lugs oi the matrices. This embodiment acts as follows:-1\t'ter the eles vator has moved away from the casting position in which it is represented in Fig. l.

'the matrices and as it approaches the second elevator, the arm 10 of the lever 7, engages with the stop 11 as shown in Fig. 2, whereby the leveling bar or matrix lifter 6 is raised from the position shown in Fig. 1. to that shown in Fig. 3, passing through that of Fig. 2. As the said matrix lifter rises, it raises the matrices l, the engagement of their be'vcls 15 with the cam 14, causing the lower ends of the matrices to swing edgewise to the rear. When the matrix lifter (3 has completed its rise as in Fig. 3, it has raised. the matrices i to the common or normal level, the beveled lugs of 41- entcring the well-known groove 16 in which also are the correspond ing lugs of the matrices 2. The mold 5 moves to the rear immediately after the linotype is cast, and the matrices have a little play in the elevator 1, so that there is nothing to prevent their swinging in the way described. The groove 16 may be rectangular in cross section as heretofore, or it may be 0 the crov .r-section shown, the matrices :2 hav ing their corresponding lugs correspondingly shaped. its the elevator 1 descends to its origii'ial position, the arm 1.0 moves out of contact with the stop 11, and the spring 13 depresses the matrix litter 6, into its normal position.

Referring to Figs. 41 and 5, the former shows the relative positions of the respective parts included in those figures, when they are in the casting position, and the latter, the lil; e,.when the elevator 1 has completed its rise. The embodiment now under review, dil'l'ers from the one previously described in that the leveling bar or matrix litter engages with. the feet of the matrices 4: instead of with one of the top lugs thereof, and the leveling lever under the elevator 1 instead of within it. Thus, 17 is the matrix lifter; 18, the leveling lever fulcrumed at 19, and carrying 17'; 20, a roller on the lever 18; 21, a projection or cam on the machine frame with which the roller 20 engages to make the lever 18 raise the matrices 1; and 22, the spring to return the lever. 23 is a stop operatively fast to the first elevator 1 and serving to limit the downward movement of the lever '18 relatively to the saio. elevator, as shown in Fig. 1.

The embodiment illustrated in Fig. 6, diilers from that illustrated in Figs. 1 to 3, in. that the rear wall of the elevator 1 is movable toallow of the matrices swinging edgewise, instead of the play .above men-.

tioned, being relied on for that purpose, and further in the variant position of the matrices being above, instead of below, the normal one, and the leveling being dowin ward. Thus, let is the rear wall of the elevator 1. separate from it, and fast to bars 25 (only one of which is shown) pivoted by their top ends to the rear end of a bracket 26 fast upon the elevator .l. 37 is a spring eeaevr l pulling on the said wall 24: from the said bracket, to'hold it in its working position. 28 is a leveling bar or matrix depressor over hanging the to rear lugs of the higher matrices 2. 29 is the leveling lever fast to the bar or depressor 28; 30, its fulcrum and 31, its returning spring. The outer end 32 of the lever 29 is curved-upward and rearward, and carries a roller 33, into the path of which extends a. projection 34 on the machine frame, so that, during the ascent of the first elevator 1, the said end is pushed to the rear and downward. 35 is a bevel or cam on the top edge of the ledge 3, and 36, a bevel upon .the bottom edges of the cooperating lugs of the matrices. As thebar '28 is depressed in the manner above indicated, it engages and carries with it the elevated matrices, which are simultaneously swung outward to clear the ledge 3 because of the engagement of the bevel-surfaces just described, this swinging movement being permitted and facilitated by the pivoted mounting of the rear wall 2 1.

If desired the before mentioned bar or matrix litter 17 and bar or matrix depressor 28 may be provided with, or substituted by, rollers, to reduce the friction at the time at which they are caused to raise or lower the matrices. desired, also, and although not so shown, the projection or cam 21 may be adjustable relatively to the machine frame by which it is supported.

The terms matrix and matrices are to be read s including type dies; and the term elevator, as including any conveyer or means for moving the composed line toward the distributing mechanism, irrespective of its direction of motion.

Having described my invention, 1 claim and desire to secure by Letters Patent 1. In a typographical composing machine, the combination with a supporting ledge adapted to support a series of matrices at a variant level above the normal level, of a matrix depressor adapted to lower the matrices from said variant level to the normal level, and a device adapted to swing the matare being depressed by the said depressor.

2. In a typographical composing machine, the combination with a supporting ledge adapted to support a series of matrices at a variant level above the normal level, a matrix depressor adapted to lower the matrices from said variant level to the normal level, and a device adapted to swing the matrices edgewise clear of the ledge while they are being lowered by the depressor, of a relatively stationary cam with which the matrix 'deprcssor makes operative contact for causing it to make its matrix-depressing stroke.

8. in a typographical composing machine, the combination with a conveyor adapted to convey mat l'ices toward the distributing rices edgewise clear of the ledge while they mechanism a supporting ledge stationary in such device, adapted to Support the matrices out of their normal level therein, and a movable device for moving the matrices to their normal level in the convcyer during their moven'ient toward the distributing l'm chanieni, of a cam on the conveyor adapted to cooperate with the matrices so as to swii'ig them edgewise during such movement.
