that `w en the lug 34 engages nger 33 the pawl 23 has passed into the cut-out portion ofthe flange of cam 29 so that no resistance is offered thereby to the forward movement The foregoing is a description of one of Mergenthaler machine, the con struction'of which is well known in the art, to which my. improvementsare applicable; but I do not' desire myself understood to be limiting the 'same'to the specific a plication shown.

ATn Fig.- -1 the mold.- 'sk isshown in position to have the type-bar ejected therefrom, its

receiving position 'being yat a right angle thereto, and opposite these ,two points of re'- 'eeption and ejection provide air-blast means whi `3h comprises a supply-pipev 36, having atV itsupper end the'V tw'yer 37., adapted to disohar e va'continuous blast of air or other cool-- 1jing agent .onto the mold and disk, therebal# ways tending to cool the mold-disk an eX4 ,tellin injurious fumes from the operator,

and w en the mold moves to its ejectin position it'will'be subjected to a direct coo 'n'g- This vertical movement of the.

valve 38, which is depressed against tension y of spring 39 by an arm 40, supported on the vise automatic stop-rod 41, whereby when the latter is depressed by the elevator, as in usual practice, said arm is also lowered to depress said valve and allow its peripheral groove 42register with the bore of the ipe, and therebyallowthe air to pass freely tiierethrough. l

The arm 40 is rigidly connected to a circular o en body mounted on the said lookin rod or rotation between collars 43 and 1s formed on its two faces vith opposite bosses 44, onwhich said body can rock,'so as to have its locking-tooth 45 disengaged from a correspondingly-sha ed notch 45, formed in vthe lower face of t e upper collar. Thus when it'is desired that the valve should not be operated upon reciprocation of lockingrod41 the outer end of said arm is manual y lowered to disengage its tooth from notch45 'as heretofore stated, and then swung to one side of its operative position until its tongue n a es in another notch, as 46, wherein it 1s he d y suitable means, as spring 47.

My object in having arm y40 mounted for rotation is to enable the operator toV swing the same out of its operative position, if desired, when the matrices are employed, as these in being conveyed back to the maga zine ordinarily have ample time to cool; but when a dash-block, as 48, (see Fig. 4,) is

yused, it being understood that in this type of machine the dash-block is raised and lowered continually by the elevator and not forwarded to a magazine, as is the case with respect to the matrices, the block is given no time for rest, and conse uently not allowed to cool sufficiently. T erefore when the dash-bloclris in use it is desirable that a cooling agent be discharged thereonto when the block moves directly in front of the' mold, and the means heretofore described effects this result by operating valve 38 intermittently.v This dash-block is supported between the back and front jaws 49 and 50 of the elevator-head' and is perforated, as shown, so that air received from pipe 37 and passing along the channel in a face-plate 51 will circulate therethrough and about the rear face of the ,linotypedash-plate 52.

In operation after the assembled line of type or matrices have been delivered into the jaws of the elevator and the latter lowered, as heretofore described, metal-from the melting-pot is forced by a plunger (not shown) into the mold, and during this operation the vdash-block or matrices are subjected to a YTO Inj',

l mold comprising a base v, 'the base part to form a vand being formed in its ylocking-rod 41 having opened valve 38. i The ejector moves forward and e'jects the type' bar, and as Will be observed, themold durin its 'rest wilLbe rapidly cooled.

Iiaving thus fully descrlbed my invention, what I claim` as new, and desire to secure by Letters Patent,`vis-' '.1`. In a machine of the-type'set forth, a
