TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Patented eluly 191W.

llpplication'filed September 2351915. Serial No. 52,145.

To all whom z'tmay concern:

"Be it known that I, FIDAVID S. EKENNEDY, a. citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Typographical lt lachines, of Which'the following'is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographicalmachines, such aslinotype machines of the general organization represented in Letters Patent of the United States to OfMergenthaler, No. 436,532, wherein-circulating matrices are released from a magazineinthe 0rder in which their characters are "to appear in print and then assembled in line, thecomposed line transferred to=theface of a mold, the mold filled with molten metal to form a slug or 'linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through -a distributing mechanism to the -magazine from Which they started.

In such machines, the release of the matrices from the ma gazin'e is efif'ec'ted by? means of cscap'ements acting through openings in the bottom thereof, and in some instances these escapements are attacheddirectly to the magazine, While in otherinstances they are'supported independentlythereof. When the escapements arethus independentlysupported, it becomes'necessary'to lock the matrices in the magazine before it is removed fromthe machine, as otherwise the matrices would be free'to 'escape therefrom. This is ordinarily insured against by employing devices which Willpreventthe removal of'the magazineuntil the matrices have'first been locked therein, such as shown in the U. -S. Patents Nos. 829,868 and 1,101,282 to Thomas S. Humans. In' the first *of the'se patents, in effecting the removal of the magazine, it is lifted out of engagement with the escapements. "and the locking-tie vices above mentioneclx'serveito prevent the premature raising of the'magazin'e; Whilein the second patent,:before themagazine' is removed. theescapements are lowered out of operative relation thereto, :and the locking devices serve to prevent the movement of the escapements'as distinguished from that of the magazine.

ll [y present invention is intended toproyide devices 'in either class of machine, whereby the locking of the matrices in the magazine is effected automatically during itsiremoval ancl so as to avoid the delay incidc'nt to the :old practice anc. to relieve the operatorof any attention on his part. In "the present instance, and as will be fully pointed out later, this automatic locking of the matrices is'controlled by devices which hold the magazine in operative position or in operative relation to the escapements.

In the accompanying drawings, 1 have shown my invention merely in preferred formand by Way of example and as applieditothe particular style of machine mentioned, 'but obviously many alterations and variations may be :made therein and in its mode of application, which will still be comprised Within its spirit. Thus it may be applied to other forms of typographical 'machines, such as typesetters, and the like, which handle type or dies instead of matrices. Generally speaking, I desire it to be understood that Ido not limit myself to any specific .form or embodiment, except in so far specified in the claims.

Referring to the drawings:

Figure l is a perspective view of the lower part of a linotype machine with my invention applied thereto;

Fig. 2 is a vertical section through the lower endoi the magazine and the escapements, and showing the magazine unlocked and ready for removal; v

Fig. 3 is a similar view showing the magazine locked in position; and

Fig. 4 is a section on the line of Fig. 3.

The magazine A, Whereinthe matrices X are stored, comprises as usual the side plates A and theedge plates or bars A, the side plates being formed in their inner or opposing faces with the converging grooves 3A providing channels for the matrices. As illustrated herein. the magazine is removablv supported in the machine upon the fixed frame which also gives independent sup port to the escapements C. which pass through openings A7 in thebottom plate of the magazine to control the release of the matrices therefrom. and are operated from thekeyboard in the usual Way through the vertical reeds C lZn the present instance, therefore, the disengagement of the escapements from the magazine takes place when the latter is raised from its supporting frame B for removal, as distinguished from swinging the escapements out of operative relation thereto, and such disengagement may be prevented by holding or looking the magazine in operative position upon the frame. Devices subserving this purpose are shown herein and comprise a pair of plates D attached to the opposite edges of the magazine by screws A passing loosely through fore-and-aft elongated slots D in the plates so as to permit them to be slid forwardly and backwardly on the magazine. At their forward ends, the plates D are provided with hooks D to cooperate with pins B projecting inwardly from the opposite sides of the frame 13, the hooks being of such extent that in the forward position of the plates they engage beneath the pins and prevent the raising of the magazine, as illustrated in Fig. 3, while in the rearward position of the plates, they clear the pins and-permit such raising, as indicated in Fig. 2. If desired, the plates D may be provided with grip pieces D to facilitate their movement.

At its upper side the magazine is also provided with a comb plate E arranged to slide vertically between a pair of fixed guide bars A so as to project its teeth E into, or withdraw them from, the magazine channels. In the lower position of the plate, its teeth stand across or in front of the upper ears of the leading matrices in the magazinechannels, as indicated in Fig. 2, thus preventing their escape therefrom; and in its upper position, the teeth are withdrawn from the magazine channels or out of the path of the matrices, as shown in Fig. 3, thus permitting their escape. The transverse movements of the comb plate E are effected by the sliding plates D, the former being provided at its opposite ends with projecting pins E engaging in inclined cam slots D in the upper edges of the latter. The slots serve by their cooperation with the pins to raise and lower the comb plate as the plates D are shifted forwardly and backwardly, respectively, they being plain or straight at the front, as at D*, so as to maintain the comb plate depressed when the plates D are in their rearward position. When the plates D are slid rearwardly to disengage the hooks D from the pins B? and unlock the magazine for removal, the comb plate E is shifted automatically to locking position, that is, with its teeth E projecting into the magazine channels; and when the plates D are slid forwardly to lock or re-lock the magazine in position, the comb plate is shifted upwardly auto matically to unlocking position or to withdraw its teeth from the magazine channels. In short, the arrangement is such that the locking and unlocking of the magazine effects the unlocking and locking of the matrices therein, respectively.

As shown in Figs. 2 and 3, the rear faces of the teeth E are beveled or inclined as at E so that as they are projected into the magazine channels by the downward movement of the plate E, they will push the matrices rearwardly a slight distance and thus provide clearance between the matrices and the escapements as the'magazine is reby cam pieces B projecting upwardly from the frame 13, but when the magazine is lifted from the frame, the pins A are re moved from the control of the cam pieces and are thus allowed to enter the holes D and lock the plates D against movement. Similarly, when themagazine is replaced upon the frame B, the cam pieces B reengage the pins A and push them out of the holes D thus releasing the plates D and allowing them to lee-moved forwardly to lock the magazine in place. The efl'ect of this arrangement is that the matrix retaining plate E is automatically looked and unlocked in its active position as the magazine is removed from and replaced in the machine, respectively. It will be noted that the inturned flanges D are also formed with slots D opening into holes 7 to enable Normally the pins A are prevented from entering the holes D them to clear the cam piecesB? as the.

plates D are wardly. i

As previously stated, I have shown my improvements merely in preferred form and by way of example, but obviously many changes and modifications will suggest themselves to those skilled in the art without shifted forwardly and back departing from the scope of'my invention.
