Application 1ed January 28, 19271. Serial No. 16%;189.

This invention relates to escapement devices such as are employed in commercial y linotypev machines to control thel releaseof matrices from their storage magazine. Or-

t dinarily, the escapement devices comprise, for each magazin-e channel or matrix column,

a centrallypivotedroclrin'g lever and a pair .of inatrixengaging pawls or verges attached .to the Opposite ends thereof, these pawls bethrough suitable `openings cut through one of its side plates. The esoapements asthus constituted are usually actuated by a series of'vveitical reeds Operated by pivoted yoles or levers each containing a rotary cam or eccentric which is adapted to malte peripheral ContactA with an underlying constantly rotating rubber-covered roll. The pivoted yolres are held normally with their cams at 20 rest and out of Contact with the rubber-covered roll and are released by the manipulation .of finger lreys .which permit the cams to fall into engagement with the driving roll and be rotated thereby to raise the yokes andl 25 operate .the escapements.

VThe object of the'preseiit invention is to simplify the foregoing arrangement and to Obviate many'of the objections attendingthe use of sucharrangement. i To this end, it is proposed to malte the esoapement devices in the form of rotatable cams which are mountedbeyond the delivery end of the magazines and are adapted bytheir rotation to release the matrices, one at a time, into the'tixed assembler throat. These 'escapement 'cams are loosely mounted oii a metal driving` roll and are capable of being individually coupled thereto by key-controlled clutch members which are pivotedv to the cams'and are provided with teeth arranged to engage one or another of several longitudinal grooves' formed in the driving roll.

` In the accompanying drawings, the invention has been-shown merelyfin preferred form and by'wayof example and as applied rto a linotype machine, but obviously many changes'and variations may be lmadev therein and in its mod-e of application which will still be comprised within itsscope. For instance, it is equally applicable to machines which handle type or type dies instead of intaglio matrices, and the reference hereinafter to matricesv is intended to include such male vorzoameo typographical elements. It should therefore be understood .that the invention is u ing projected alternately into the magazinenot limited to any speoiiic'form `or embodiment except in so -far as such limitations are spcciiied in the claims.V 'l

In the drawings: y y

Fig. l is a vertical section taken through the lower end of a linotype magazine andthe associated assembler throat, showing the application of theimproved escapement device;

Fig.r f2 is a similar View showing the device in the act of releasing a matrix; Fig. 3 is a section talren on line 3-3 o Fig@ l; and f f Fig Llis detail perspective view of one of lthe escapement units.

As shown in Fig 1, the matrices X are stored in `two or :more superposed (.:lianneled magazines A which are shiftable upwardly and. downwardly inthe machine frame so that the selectedl onemay be brought into operative relation to the tixedassembler throat B. Normally, the matrices are looked iin their respective magazines by the usual locking rod A1 but when afont'isk selected for use, the-rodis withdrawn or otherwise rendered inactive so that the matrices may be allowed to escapefrom the magazineun-V der thel control of escapement devices which release them, one at a time, vand allow them to pass by gravity into throat B for composition, in line at a lower level. i

' Thel improved escapement devices which constitute the subject'matter of the present invention comprise a series of rotatable cams C located beyond the lower or delivery endV of the magazine and mounted on a constantly driven metal ,roll C?, the `latter `being 'journaledwat its opposite ends in bearing arms C2 pivoted to the xed framework and whichpermit the escapements to be rocked forwardly 'out of the way of the magazines as the latter are interchanged inoperative position with each other. A pull spring C5 a stop screw'C4 banking against the back ,plate of the throat B` serve to maintain and locate the esoapeinent cams in operative relaion tothe magazine being used. The cams @correspond in number to the magazine channels andare 4arrano'ed to en age and connected to one ofthe bearing arms C2 andv i ou VB (see broken line Fig. l).

formed with a pair of low .non-concentric `Jortions C alternatin(y with the high Jorl. L? t1 tions (J5 and whichv permit tlieniatrices to slide forwardly from the magazine in the rotation of the cams, as well as with a pair of shoulders@T iiiterii'iediateof the respective pairs of high andA low portions and adapted to engage the matrices, and support them momentarily during their passage I sides of thefcams. Flanges or hubs C104 formed on the cams serve to maintain them in spaced relation on the roll C1 and the widths thereof vary according tothe spacing of the magazine channels. The, pawls C9 are each formed with a tooth 01 projecting inwardly therefrom and arranged to engage one or another of several grooves c formed in the driving roll C1 and extend- -ing' throughout lthe length thereof. kPlate v springs C11, anchored to the cams and pressedfagainst one end of the attached pawls, tend constantly to move the teeth into engagement with the grooves c2, it being noted thatthe hubs C10 are notched or cut away to permit passage of the teeth therethrough. ln order to hold the pawls normally disengaged from the driving roll against the tension of the springs C, they are foi-ined with diametrically opposite banking surfaces 03 c4, one or the other of which is adapted to engage the free ends of pivotedtrip levers D at every half-revolution of theV cams C. These trip levers are connected-at theiropposite ends to Va series of vertical reeds E slidably mounted in the machine and which, in the present instance, are connected directly to the finger keys F of the keyboard. A l

. According to the foregoing arrangement, the depression of a linger key F rocks the associated lever D through the intervening reed E andtrips the clutch pawl C ofv the corresponding escapeiii'ei'it cam C, permitting the tooth C1 of said pawl lo be pressed vby the spring C- into driving engagement with one of the grooves 02 of the driving roll C and thus causing rotation of the cam in the direction indicated by the arrow in Fig.

l. As the active concentric portion C passes out of engagement with the leading matrix of the column, the adjoiningreduced portion GG comesy into play and allows the matrix to slide forwardly against the intermediate shoulder C7 and, as thecamk continues `te rotate, the matrix is supported by said shoulder until it has passed completely out Vof the magazine upon the reduced portion C of the cam (see Fig. 2). At-this moment, as will be noted, the vupper end of theescapiiig matrix is liftedA slightly by the cani and the other concentric portion C5 passes beneath the lower endof the next orV succeeding matrix of the column. A slight further rotation of the cam disengages the shoulder CT from the escaping matrix and releases it entirely, the second concentric portion holding back the next matrix.V In

the meantime, due to the release of the iinger key, the trip lever D will have resumed its normal position so that, when the cam has about completed a half-rotation in effecting the release of the matrix, the banking surface 03 or c4, as the case may be, of the clutch pawl engages the free end of said lever and forces the tooth c1 out of'engagement with The speed at which the roll C1 is driven may be determinedby the time it ordinarily takes a matrix of average thickness to pass from its `position of rest within the magazine to its releasing position. e. g., if .the roll were driven at too great a speed, thereduced portions C of the cams might engage escaping matrices before they had time to leave the magazine and bind them against the upper plate thereof.

Many advantages characterize the iinyproved construction. lAs will be apparent, the mechanism is self-contained, easily assembled, and inexpensive to manufacture, as well as positive and reliable in operation. Moreover, a single bankor row of the escapement units, due to their independent mounting will suffice to control the release of matrices from any desired number of magazines, and this without changing the general structure or organization of the machine. Since the escapements are located beyond the magazines, the latter may be brought much closer together than ordinarily. The magazines themselves are simpler and may be produced more cheaply than those now inr use. the bottoniy plates being"unapertured and solid throughout.

lli() The improved escapement is `not only well adapted to cooperatewith` the standard in atrix without change, but it-is also capable of functioning equally well with earlessl matrices or matrices of plain rectangular form. These and other advantages will be readily appreciated by those skilled in the art. Y l i its prei'fiously stated, many Vchanges and variations in theoilstructioll. im@ Opeldf.0.1i

of the improved -device may be made and still be comprised within-the spirit of the invention. For example, while the connection and disconnection of the escapement lcams with and 'from the driving roll as above described iseifected by means of Vfclut'ch pawls, it is obvious that such connection could be established in various other ways. Again, the release of the individual Amatrices coiild'be accomplished in a way similar to that disclosed if the escapement cams were formed with a greater or less number of vhigh and low surfaces lwith their intermediate Shoulders. The invention is therefore not limited to any specific form or embodimentexcept inso far as such limif tations are specified in the appended claims.
