nmoTYPE-MAcnmE.

To all whom it may concern: I 7

Be it known that I, Tnonas SIMMONS HoMANs, of the borough of Brooklyn, County of Kings, and State of New York, have invented a new and useful Improvement in' Linotype-Machines, of which the following is a specification. I v

My invention relates to linotype machines of the general organization represented in Letters Patent of the United States No. 436,532, in which afont or set of circulating matrices is carr ied a-magazine, their release therefrom, one at a time, being effected by escapement mechanism controlled by finger keys. In order to permit speedy change in the style or face of the typeproduced by the machine, the magazine is commonly made removable so that it may be replaced by another containing a suitable font of matrices. In some cases the magazine has been made removable independently of the escapement mechanism, which remained on the main frame.

The aim of the present invention is to provide for the speedy and easy removal of the magazine independently of the escapement mechanism and at the same time to avoid certain objections and inconveniences which attend the constructions heretofore in use.

To this end, I combine with the inclined magazine an underlying escapement mechanism attached to the main frame, and an underlying vertically movable frame by which the magazine is supported, this frame and the magazine being so constructed as to admit of the magazine being withdrawn from the side of the machine after it has been lifted clear of the escapements by the rise of the movable frame.

I have confined the accompanying drawings to the magazines and adjacent parts, as all other parts of the machine may be of ordinary construction.

' a Figure 1 is a side elevation of the upper part of a linotype machine having my improvements incorporated therein, thev magazine being in operative position.

Fig. 2- is a similar view, with the magazine lifted preparatory to its removal. Fig. 3 is a perspective view of the same parts, with the magazine withdrawn from its position and-suspended at-one side preparatory to removal. Fig. 4 is a vertical. longitudinal section through the magazine and escapement mechanism, said parts being in the, position shown in Fig.- 2, with the magazine lifted clear of the escapements.

which .the' magazine is supported; D the escapement mechanism fixejd to. the main frame and underlying the magazine; It the vertically channeled plate or raceway Specification of Letters Patent. Application filed June a2, 1906. Serial No. 322.858.

Patented J'uly 2 1907.

" end. of the frame 0 rests normally on the main frame.

For the purpose of raising and sustaining thelower end of the frame 0,. a shaft G is extended therethrough and provided at opposite ends with eccentrics g, bearing on the main frame, and with anoperating handle g. -By turning the handle, the eccentrics are rotated and caused to lift the frame 0, which may be sustained in its elevated position thereby, as shown in Figs. 2 and 4.

The magazine, which consists-as usual of two parallel grooved plates secured to intermediate spacing pieces, is seated on top of the frame 0 and provided on the under side with transverse horizontal ribs 0 which are seated in correspondinggrooves in the upper face of the frame, the construction and arrangement ofparts being such that when the frame is in the elevated position shown in Figs. 2, 3 and 4, the magazine may be drawn laterally therefrom and permitted to swing or tip downward at one side of the machine, as shown in Fig, 3. The ribs e have their rear or left hand ends fashioned into hooks c, and the side of the frameO is so formed thatwhen the magazine is fully withdrawn from the side of the machine, the hooks c engage therewith and arrest the further outward movement of the magazine, and at the same time'serve as supports to sustain or suspend the magazine when it is permitted to turn downward, as shown in Fig; 3. After the magazine has reached this position, it may be conveniently unhooked and removed. I

The escapement mechanism consists, ,as usual, of a supporting bar or'frame slotted transversely to receive centrally pivoted escapement levers d, each carrying at opposite ends two parts d and d adapted to extend upward alternately into the magazine to engage the matrices therein. The upper surface of the escape ment bar, through which the pawls are projected, is preferab y formed as shown, with longitudinal ribs, in order to guide the pawls near their upper ends, and the under side of the magazine is provided with transverse slots b, b, of suitable size, to admit said ribs. This construction in itself forms no part of the presentinvention.

. The magazine is applied to the machine by first hooking it to the 'side of the frame 0, and thereafter turning it upward and pushing it home transversely of. the machine to its place on the elevated frame 0, after which the frame is lowered to-its operative position,

thereby lowering the magazine until the escap'ement pawls and ribs assume their operative positions in the Under side of the magazine,

The removal of the magazine is effected by first lift: ing the frame C arid thereafter drawing the magazine from the machine over the side, as above indicated. It will be observed that it is only necessary to lift the magazine a slight distance sufficient to disengage it from the escapement mechanism and permit its withdrawal thereover. It is not necessary that it should be lifted high enou h to clear the channeled plate at the front. r

It will. be observed that the present organization permits the use of a continuous or undivided magazine of full length, adapted to contain all the matrices in the machine, and it provides for the removal of this magazine and all the contained matrices laterally from the machine Without disturbing the escapement mechanism, which remains on the main frame in position to co-operate with the second magazine when it is in turn applied to the machine.

Having described my invention, what I claim is 1. In a linotype machine, a main-frame, and an escapeframe having transverse interacting guides, adapted to permit the lateral removal of the magazine independent of the escapement mechanism.

2. in a linotype machine, the combination of :i main frame, an escapement mechanism fixed thereon, a inn-nzine overlying the escapement mechanism and co-opernting therewith, means for lifting and sustaining the megazine clear of the escapement and means for guiding the magazine laterally from the machine.

In testimony whereofl hereunto set my hand this twentieth day of June, 1906, in the presence of two attesting witnesses.
