To all whom it may concern:

Be it known that l, PHILIP TELL DoDGE, oi the borough of Brooklyn, county of Kings, and State f New York, have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

My invention has reference to linotype machines of the general 'character represented ih Letters Patent oi. the United States #436,532, and kindred machines,` 10 wherein circulating matrices, representingA the various v l characters, are stored in channeled magazines from which they are delivered by escapement mechanisms and linger keys, one at a time, to be composed in lines l5 chines are commonly constructed in such manner that the'magazine may be removed and replaced by another containing matrices for type aces of a different size or style. Heretoo're it has been the general practice to provide. each magazine with anescapement l mechanism incorporated permanently' therein and ently removed and Yvarious magazinesused with the one escapeinent mechanism. Owing to the iact that the escapement devices must be constructed and adjusted in vrelation to each other and to the magazine withfextreme precision, the last-named construction demands costly tools and -is very expensive. Beyond this, it is open to the objection that the vslightest springing or bending of the parts will prevent the their proper relations.

The object of my invention is to attain the advantages of'both the older constructions without the disadvantages of either. T o thisl end, I construct the magazine and the escapement mechanism each as a complete unitary structure, and connect them by.devices whichiwill admit of their being readily separated so that the magazine seated on and supported by the main 'frame will serve in turn to support ,the escapement mechanism connectedfirmly thereto. hThis construction insures the proper relationship of the magazine and the escapements, and permits the use of the\`one escapement mechanism-with a number of magazines. The escapement vmechanism including the escapements proper, their supporting bar, and their actuating springs may be removed from the machine-with the magazine, and thereafter separated and applied to\a second'magazine, but I` prefer to disconnect the escapement from the magazine before the'latterA is re# tion.

magazine and' escapements from coming together in 'anism may be left loose-on the main frame or other support in position to be connectedto thenext maga'- zine which may be applied to themacln'ne. n

-The form of' the escapement devices and the details oi the connections between the escapementsand' the 60 magazine maybe widely varied within the ylimits of mechanical skill land without passing beyond the scope of my invention. i y

Referring to the drawings,'-.Figure l-is` a vertical central section from irontto rear through a magazine, escapement mechanism and the attendant parts, constructed in accordance with my invention, theparts being in operativeposition. Fig. 2 isa similar view for presentation to a casting mechanism. These mawith the magazine detached from the escapeme-nt and lifted preparatory to its removal.` Fig. 3 is a similar 70 section showing the parts in a modified or alternative form; l A v 'I Referring to the drawings, AY represents the rigid main frame, whichmay be oi any suitable construc- B is the inclined longitudinally channeled magazine adapted to receive and carry the'matrces O, as usual.

D is a vertically movable base frame, underlying and supporting the magazine secured inA thefmain frame and -forming in effect a part thereof. p 480 E-is the vertically channeled front plate or racewayv u into which the matrices are delivered from the respec tive channels oi `the magazine, from which they pass to the usual assembling mechanism.

F represents the escapement mechanism iconsisting of a rigid bar or iramef, of any suitable construction, containing the series of escapement levers f', each lever bei ing mounted on a central pivot and provided onitsen'ds with two upwardly extending pawls which are proj ect'- ed alternately upward through the bottom of the magai zine by the oscillationy of the lever.` There is one ot" these escapement levers for each-channel oi the magazine, and in theirgeneral form and arrangement they operate to release the matrices' one at 'a time in the same manner as in the commercial linotype machine of the 9K5 present day. Each escapement lever is acted uponl bya spring f2 attached to a iiangeon the escapement bar and tending to4 draw the lower escapement downward .from the magazine. Each escapernent is also acted upon by a vertically reciprocating bar or reed G urged vl0() constantly downward by a spring H sufciently strong i to overcome the s'pringfz. The finger key mechanism is connected with the bars G in the-same manner as inthe ordinary linotype-rnachines, or in any other suitable manner, 'to lift the bars and permit the es'capernents to l() 5 reverse their positions anddeliver the matrices..V -The reeds G will be guided .as'usua'l by movable supporta,

this being an' ordinary feature in all linotype machines',

and foreign to the present invention'. l .f I

zine and from its operative position, and rest tempo- Instead of the sliding bars represented in Figs. l and v the magazine and forming part thereof. The escapemagazine .is in the machine and filled with matrices i they should be locked in the magazinefto prevent their accidental escape. Various devices are known for this purpose-such as the transverse removable rods shown at N in United States Patent No. 548,432, or the rock shafts L as shown in the Patent 77 6,77 9.

l lt will be observedthat the under plate of my magazine, .which gives support to the matrices, is continuous and extended to the lower extremity of the magazine so that the matrices may be confined and supported in .the magazine when it is removed from the machine, holes or slotsl being formed in said under plate to permit theupper ends of they escapement pawls to rise therethrough.

' The escapement bar and its pawls and levers constitute in themselves a complete or unitary structure wholly independent of the magazine and of the main frame. The escapementbaris applied to the under side of the magazine and is secured firmly butremovably thereto in the exact position required, by locking devices which may-be of any suitable form, provided they are adapted to effect its instantaneous connection and release.

In-Fig. l, the connecting devices consist of transverse keysor bars I and 1, each seated at one edge in a groove in the escapementbar, and at the opposite edge in a bar J, secured-'rigidly and permanently to the nndeiside of mentis not seated upon, connected to or sustained by themain frame. 'On the contrary, it is secured by the bars I directly and rigidly to the magazine so that it receives support therefrom. By thus attaching the escapement directly and firmly to the magazine, l am enabled to prevent it fro'm warping, twisting or changing its relation to the magazine, and consequently eaeh and every pawl is compelledto rise and fall v.the exact distance required with reference to the upper surface of the magazine plate and the matrices riding thereon. When the escapement mechanism is to be disconnected, itis only necessary to withdraw the bars or keys I endwise thereby permitting the escapement barAto fall away from the magazine; or, if preferred, the escapement bar may be withdrawn 'endwise as hereinafter described. l

When the magazine is to be removed, it is preferably lifted clear of the channel plate E by raising the frame D, as shown in Fig. 2, after which the magazine may be removed from the machine in a forward direction. This 4may be done before the escape-ments are disconnected so that they may be detached after the magazine has been removed from' the machine. In such case, the escapement mechanism will be secured to a second magazine before it is in turnapplied to the machine. .I prefer, however, to effect the disconnection oi the escapement before the magazine is lifted and removed., In such case, the escapement, when released, will fall'slightly away from the magavi'arily on the main frame or other support, so that it will bein convenient position to be lifted into engagement siton.

2, I may employ two rotary locking bars I2, flattened on one side and seated in opposite sides of the escapement mechanism, the form and arrangementbeing such that after the magazine isv in place, the escapement may be lifted into contact therewith and secured by turning the bars. A skilled mechanic will understand that these locking devices may be mad e in a great variety of forms,

the only requirement being that the escapement mechanism shall be firmly secured along vits two longitudinal edges to the magazine.

lt will be observed that in Figs. land Zfthe under side of the magazine, although ofA full length, is provided with two transverse slots b and b to receive ribs onv the upper side oi the escapement frame, these ribs serving to guide the escapement pawls to their extreme upper ends, and also serving to fill the slots when the escapement is locked inits operative relation'to thel magazine, the ribs forming in effect a part of the under plate of the magazine. These ribs are not', however, a necessary feature of the construction, and ythe under platel of the magazine may be made continuous, as shown in Fig. 3, with only small holes therethrough forthe passage of the upper ends of the pawls. When the magazine is grooved on the under side, the escapernent bar may be inserted and removed endwise. In such case, vthe locking bars I and If may be secured perrna-4 nently in place to the magazine or to the escapement mechanism or replaced byv a tongue formed in either of these parts and extending into the other.

The removal of the escapement bar endwise from theV i magazine is of advantage in that it permits all the es.-

capements to be instantly Withdrawn from the ma.-

. chineas is often necessary in order to repair, clean, or'

adjust them, or -to remove any obstructions-without removing the magazine or otherwise disorrxanizing the machine.'

While I prefer to employ escapement levers in the form shownthe form in general use-t will, of course,4

be understood that they maybe varied at will, a number of suitable forms being already known in the art.

Having described my invention,what I claim is:-
