Y y28 Claims. Thisinvention relates to typographical machines, such as Linotype machines of the` gen-l eral organization represented in Letters Patent of the United StatesNo. 436,532, to O. Mergen- 'tha1er, wherein circulating matrices vare released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold lled with molten metal to form a slug' or Linotype against the matrices which produce the type characters thereon, and

l the matrices thereafter elevated and `returned through` distributing mechanism to the magazine from `which they started.

l More particularly, it relates to machines equipped with a `pluralityof superposed magazines containing different matrix fonts and which are arranged to be moved as a unit upwardly and downwardly in the machine to bring one or another into operative relation to the assembling and` distributing mechanisms. In such machines, the magazines are independently removable and` replaceable and, to thisend, are arrangedto be spread apart in order to permit access to the magazine to` be removed which, for thispurpose, is rst located in operative position. Provision is also made for` raising the magazine to be removed on its supporting base frame clear ofthe assembler throat, so that it may be drawn forwardlyby the operator and supported in a vertical position at the front of themachine` by arms pivotally arranged on the machine frame and adapted tobe swung into a position to supportthe magazine in the manner stated. The replacement of a magazine is effected by reversing these operations.

'I'he pivotally mounted supporting arms are,

permanently secured tov the machine frame and normally located in an inoperative position `alongside of the bank of magazines. `As `the magazine to be removed is located inoperative position, .mechanism associated i therewith is automatically brought into operative relation to devices operated by one of the pivoted arms, so that, as the arm is swungforwardly intoactive magazine supporting position at the front of the machine, such magazine (i. e., the one to be removed) will be lifted to` separate it from its base frame and locate it in a position to clear the` assembler devices during its removal `from thefmachine. `And likewise, in the case` of a replacement magazinagt-he return movement of thepvoted `arm to inactive position will lower such magazine intothe" base frame, for proper locationfwithrespect to its `assembler devices.

Also, safety elements are provided for locking the pivoted arm against movement until the magazines have been properly spread to` permit the removal of the selected magazine; and other elements are provided for-locking the magazines to their base frames, the `latter locking element being released by the initial movement of the pivoted arm from inactiveposition and being reset in locking position by the` final return movement of the arm to zinactive position.

According to the present improvementsthere is provided a magazine spreading attachment 4 which is entirely automatic insofar` as concerns the selection of the magazines to be spread apart for the removal of the magazine inoperative position. In other words, regardless of which magazine is in operative position, the operation of the device will cause all the overlying magazines, whetherthere be one, two or three, to be spread apart` from said operative magazine and this without any thought upon the partof the operator. To this end, the base frames are provided at their opposite sides with laterally extending lugs adapted to be engaged by a. pair of vertically movable arms for spreading the magazines apart. The arms are mounted, one at each end ofa transverse rock shaft, and extend upwardly along the oppositelsdes of the bank of magazines rearward of the lugs. The rock shaftand magazine spreading arms are mounted in the` machine frame independently of the bank of magazines, and a hand crank fixed to the rock shaft is operable by forward rotation, rst to move the arms into engagement with the lugs on the base frame of the magazine (or magazines) above the one in operative position, and then to lift the arms vertically for spreading the magazines. The arms areu formed on their forward edges with a, series of l lugs (three fora bank of four magazines) arranged to engage beneath the laterally projecting lugs on `the base frames, the lugs onythe arms being spaced apart so that, as the arms move vertically, the magazines will be `lifted and spread progressively, starting with the top-most magazine. l l l 1 The present improvements also contemplate a novel linkage between the pivoted `magazine supportingarm and the device for raising the operative magazine from its base frame pre-` paratory to removal and for lowering thereplacement magazinev backinto position` on the base frame. The improvedconstruction gives an increased mechanical advantage which greatly `facilitates the operation.

The magazine base frames have also been `substantially improved. Heretofore, they were made of iron cast'in a single heavy structure comprising marginal members and intermarginal crosspieces to provide reinforcement for the marginal members as well as supporting elements for the magazine and associated mechanisms. Such cast base frames were necessarily extremely heavy in order to provide the required strength for carrying out their intended functions. These heavy units were difficult to handle during themachining and finishing processes and were susceptible to breakage because of theessential brittleness of cast iron. Furthermore, if such castings are inaccurately formed or improperly nnished in some respect, the entire unit might be rendered useless. f

According to the present inventiornthe mag-v4 -the invention is not limited to any particular form'or embodiment except insofar as such limitations are specified in the appended claims,

`The matricesarestored according to font in the superp'osed channeled magazines A, four of which are shown herein but of which agreater or lless number might be employed, if desired (Fig. 1). The top magazine is of the split variety, i. e.,it has lower and upper sections a and a1, the lower section a only containing matrices, and .the upper sectional serving to guide the distributed matrices into the proper channels in the lower section. 'I'he remaining magazines are of the usual full length, both varieties of magazines being shown for purposes later to appear. The several magazines `A are removably supported upon separate-base vframes AA1- oonlmechanism in Ithe usual way. The three upper base frames A1 are pivoted at their upper ends, by pins'A2, on a pair of plates A3, rising from the lowermostpbase frame at the opposite sides thereof, yso that the base frames supporting the respective magazines may be spread apartI to permit the independent removal of any selected magazine.V

, Asbest shown in Figs. 1 and 2, the banksof escapements E are mounted directly on the respec'tive magazines. Suchbeing ythe case, it is apparent that beforea magazine can be removed from the machine, it must first be separated from its base frame sufciently tofenable the escapements to clear the assembling mechanis`m C. For this reason, each base frame is provided with a central magazine lifting and supporting plate F (see Figs. 4 and 5), which in the` present instance is substantially as long in a fore-and-aft direction as (theubase frame it` self, the plate being pivotally supported at its upper end in the base frame on pins F1, -thus permitting it be swung upwardly to lift the magazine. The plate F is formedwwith a1 central fore-and-aft groove F2 which accommodates a A correspondingly arranged reinforcing rib (not shown) on the underside of the-overlying magazine. lAt its lower end, the plate F is provided with a stop shoulder F3 which serves as an Iabutment to* retain the magazine in place on the plate, when the latter is in its raised position, 'by engaging a transverserib a2 located asusual on 'the underside of the lmagazine near the front.

The magazine lifting and supporting plate F, associated with each base frame, is raised and lowered by anunderlying plate cam or equivalent device G fixed to a transverse rock `shaft G1 which isjournalled in the base frame near the front end of the plate F (Figs. 4 and-5).'

In the normal position of the parts, the magazine raising andv lowering plate Fis supported at its front end vby :the magazine-base frame with the cam plate G located directly beneath it substantially in the plane of the base frame (see the magazine second from the bottom'in Fig. 4).

However, when the rock shaft 'G1 is turned in a` clockwise direction, looking at the machine from the left, theplate G will engage the underside of theplate F and cam the latter upwardly, thereby raising the magazine off its base frame to a position in which the escapements E onthe maga-zine will clear:1 the assembler throat C, thereby permitting the removal of the magazine (see the lower magazine in Fig. 4). On the other hand, when areplacement magazine has been locatedupon the plate F, a counterclockwise rotation of -the rock shaft G1 will restore the cam plate G to its normal position, permitting the magazine and the plate F, by gravity, but under the control of the cam plate G, to be restored to their-normal positions on the base frame. It will be observed that the cam G is provided, on its active edge, withva hook'shaped piece G2 adapted, when' the cam is turnedupwardly,` to engage a pin F4 projecting from the right edge'of the overlying plate F and thus lock the latter in` itsproper raised position.

` The transverse rock shafts G1 have a common operating device which is automatically coupled to the corresponding shaft G1 asthe respective magazines are moved into operative position, it `being recalled that a magazine must be so located before it can be removed from the machine. As shown in Figs. 4 to 8, the common device referred-to includes in part, a rotatable member H supported in a bracket B1 fixed to the machine frame B atthe left of the bank of magazines and located in coaxial alignment with the rock shaft G1 associated with the magazinefin operative position. The member H is formed in its inner face with a grove H1 Which, in the normal position ofthe parts,'extends in the direction of movement of the shift frame. .,At `the left end of each rock shaft G1, there is pinned a collar G3 formed with vertically spaced tongues Gt which. align with the groove H1 when the associated magazine is resting on its base frame. Consequently, as a magazine is raised or lowered into operative .position by the movement of the shift frame, the` tongues G1 on the: associated rockshaft G1 will enter the grooveHl.. and couple the rock` shaft `and .member H together. If the member H is now turned in aclockwise direction, looking at the .parts from the left,.the coupled rock shaft wilL likewise-be turned` in the same direction to raise the supportingrplate'F and lift the corresponding magazine oif its base `frame. And similarly, when a `.replacement magazine hasV been locatedfon'` the elevated supporting plate E, ,the return. movement `of the memberI-I toits t `(compare Figs..l ,andfhand see Fig. 5). `Normally, however, the arm K is .prevented from` being moved toits active .position tto:` effect the separation of `ther magazine` inoperative position from `its supportingbaseframe until themagazines havebeen spread. `The means for locking the a1mK..in its normal position areA described later. cn.V `Itvvill` sufncef to say here, `that .the

means referred to are controlled by the magazine unit next `alcove fthe magazine `in operative `position, the arrangementheing such that unless the magazines have been` spread, rotation of `the magazine supporting arm K to operative position is prevented., `When the magazines are spread, however, the` locking meansis rendered inoperative, leaving themagazine supporting arm` K `free torotate.` The magazinesvare lockedon their respective base, frames, each by a pairof spring `latches M pivotally `mountedon `the base frame to engage the. opposite side edges of the magazine (Figs.` 7

and 8) The latches M are controlled byla pair of cams G5, oneformecl onthe collar G3, pre viously referred to, and the othercnacllar G6, said collars lbeing pinned to the rock `shaft )G1 at itsleft and right ends, respectively.` When the `rock shaft G1 isinits normal position, high portions G7. of .the cams G5hold theflatchesfM inengagement with the. magazine against the N1 which is pinned thereto. of t/he `magazine bank, thereis yprovided a veraction of latchsprings. M1.1 However, `when. the shaft G1 is rocked to 'separate the magazine from its base frame, its initial movement (Which is idle as far as the separation of `the magazine from its base frame is concerned) turns the` cams G5 enough to move the high portions Grl thereof out of engagement with the latches, allowing the latch springs`M1 to rock the latches outwardly from the solid to the dotted line position shown in Fig. 'I where further movement is prevented by the engagementfof the `latches with lowportions G8 of the cams. The latches are rendered inactive `by .the outward movement just referred to, thereby` leaving the magazine free to be separated from its base frame by the further rotation of the rock shaft G1. When a replacement magazine is `lowered on` to the base frame 'by the rocking ofthe shaft G1 in the opposite direction, the high portions Gr'I of the cams G5 reengage the respective latches M during the nal rocking movement of theshaft and `force the latches, againstthe action of the springs M1, into` locking engagement with the opposite sides of the magazine. l l

Except as hereinafter indicated, the mecha- .nisms thusfar described may be found in one Referring to Figs. `1,12 and 3, it will be observed that below the bank of magazines, there is pro-` vid-ed a transverse rock shaft N'journalled in bearings B2 located at opposite sides of the frame B, the shaft extending beyond the outer face of the bearing at the left to accommodate `a. crank Adjacent each side tical arm N2 formed at its lower end with Van elongated slot N5. through which the shaft N passes, the arm N2 resting, when in normal position, with the upper end of its Yslot bearing against the shaft.` Each ,armNZ `is connected to l the shaftN by a toggle consistingof a crank; arm

. N4 pinned to the rock shaft N andra link N6, the

Near their upper ends, thearms NY2 are formed on their front edges each with three spaced lugs N9, N10 and N11, arranged one above the other, and adapted when the mechanism is operated to cooperate with lugs A18 projecting from the opposite sides of each of the three upper base frames.

The magazine spreading mechanism is held in its normal position, as shown in Fig. l, by a spring clip N13 fastened to the machine frame at the `right and which frictionally engages the crank handle N1. Assuming now that the operator desires to spread the magazines in order to Vremove the one in operativeposition, `he pulls forwardly on the arm Nlluntil it banksagainst a sto-p N14 fixed in the machine frame. the crank N1 rocks the shaft N in a clockwise direction, looking at the partsifrom the left,l kand during `theffirst `st'agesof itsymovement, the arms That movementY of moved upwardly; and since the lugs N9, N111and N11 are located so 'as to underlie theV lugs A18 on the three upper base frames A1 (assuming that the lowermost magazine is the one in operative position)v when the forward movement ofthe arms N2 is arrested, the three upper magazines and their base frames will be spread apart from the lowermost magazine to permit of its remova (Fig. 2).

The mechanism operates in a similar fashion when either the second or third magazine from the bottom is in operative position, the only differen-ce being that when the second magazine is operative, the two lowermost lugs N9 and N1o on the arms N2 will cooperate with the lugs A18 of the two topmost magazines, the topmost lug N11 being idle; whereas when the third magazine from the bottom is inoperative position, only the lowermost lugs Ng on the arms N2 will be active, the two topmost lugs N and N11 being idle.

It will be noted from Fig. 2 that when' the arm N1` is full forward resting against the stop N14, the toggles have moved past the dead center position so that the weight of the magazines operates to prevent the counterclockwise rotation of the shaft N. In otherlwords, once the magazines have been spread, they will thus remain until the operator restores them to normal position by an operation which is merely the reverse of that previously described, i.'e., by a return movement of the handle N1 to its normal positiorn To prevent the separation of the arms N2 from the lugs A18, the lowermost lug N9 is formed on its front edge and at the top'with a lip N12- which, by engaging the lug A13 at the front, will counteractthe tendency `of the magazines, because of their weight, to cam the arms N2 rearwardly. Only one set of lugs need be provided with such a lip, and it is appended to the bottom lugs N9 since those lugs will alwaysv be operative when the spreading mechanism -is used regardless of the magazine in operative position.

' Due to the fact that the magazine base fra-mes have their own individual pivots at the rear, those that are swung upwardly during a spreading operation will move relatively in a fore-and-aft direction. Accordingly, to permit this motionl to take place freely without interference lbetween the magazine units, provision is made for a progressive spreading of the magazines. Thus, assuming that the three upper magazines are to be spread to give access to the lowermost magazine, the spreading mechanism is so designed that the top magazine unit is moved up clear of the underlying unit before the latter starts to move, and the latter unit in turn is moved up clear of its underlying magazine before this last one starts to move.

` To effect this progressive spreading movement of the magazines, the lugs N9, N10 and N11 on the arms N2, While spaced equidistantly .as between themselves, are nevertheless spacedV apart l at greater distances than are the lugs A18 on the different magazine base frames when the latter are in their normal positions. Consequently, when the arms N2 are arrested in their forward movement by engagement with the lugs A18, there will bel just sufficient clearance between the parts to permit the-top of the lugs N11 to pass freely beneath the overlying lugs A111011 the top base frame. `Theclearance between the intermediate lugsN10 and their overlying lug A18 will be greater, while the clearance between the lugs N9 and their overlying lugs A18 will be greatest of all. Accordingly, as the arms N2 are moved upwardly during the magazine spreading operation, they will pick up the magazine units progressively in order starting from the top. And,v of course,

when the magazine units are returned to their normal positions, they will seat one after another progressively starting with the bottom.

YTo complete the description of this phase of the invention, attention is directed to the fact that the arms N2 are guided in their upward movement, on one side by the crank arms N'1 and, on the other side, by collars N3 which, like the crank' arms N4, are pinned to the shaft N (see Fig. 3).

yAfter the magazines have been spread apart, the next stepin the process of removing a magazine is to raise or separate it from its base frame so that its associated escapement mechanism E will clear the assembler throat C. As stated previously, this is accomplished by rotating the transverse rock shaft Gl associated with the magazine in operative position, the shaft G1 in turn rotating the cam plate G to raise the center plate F and consequently the magazine.

vAs previously stated, the shaft G1 is rotated by the movement of the magazine supporting arm K into and out of its active position. It will be recalled that the rock shaftGl of the active magazine unit is automatically coupled by a tongue and groove connection to the member H as said magazine unit is brought into operative position (Fig. 7). The member H is in the form of a sleeve rotatably mounted on a shouldered screw H3 threaded into the bracket B1, being formed at the right with the arm H2 which presents the groove y VH1 and at the left with an arm H1 (Figs. 1 and 4).

The arm H4 is formed with an elongated slot H10 to accommodate a laterally extending pin H9 pre- .sented atA one end of a lever arm H7 centrally fulcrummed as at Ha andI formed at its other end with a gear segment H6 which meshes with a gear H5 formed on the hub K15 of the magazine supporting arm K; At vits free end, the magazine supporting arm Kis equipped With a handle K2 which may be grasped to move the arm into and out `of its active position. v As previously stated, the movement of the arm K from its normal position is prevented unless the magazines have been spread. The means for the -purpose includes the arm H2 which, in the normal position of the parts, extends upwardly in theY line. of shift frame movement (Fig. 7). The free end of the arm H2 is formed with an ear 11,1 which extends laterally inward from the arm and normally lies behind the lowermost tongue G4 on the collar G3 fastened atthe left'end of the rock shaft G1 on the base frame next above the magazine in operative position. Hence, before the magazines have been spread, any attempt to rotate 'the arm K to its active position is prevented by the engagementl of the ear h1 with the tongue G4. However, during the operation of spreading the magazines, the rock shaft G1 on the base frame next above the magazine -in operaf tive position is carried upward so that the tongue G4 thereon will stand clearof the ear h1, leaving the arm K free to rotate. 1

Normally, the arm K extends rearwardly alongside the'bank of magazines, and the arms H4 and H'Voccupy positions at `right angles to one another as shown in Figs. 1 and 2. However, as the arm K is swung forwardly into its active position, it operates through the gear H5 andthe gear segment Hs to rotate the arm I-li7 counterclockwise, looking at the parts from the left. The arm H7, in turn, through themedium of the pin H1'` thereon acting in the slot H10 on the arm H4, rotates the latter in the opposite direction to the position shown in Fig. 4. During the rotation of the arms H'1 and H4, the pin H9 rides from the outer end of the slot .H10 to the inner end thereof and return as the arms` H7' and H4: move from the. right angular relationship shown in Fig. 1 to the. right mentv of the arm H4 effects a correspondingmovement of the member H to impart a 90 rotation in the same direction to the shaft G1, to raisethe magazine from its base frame in the manner` heretofore described, through the cooperation of. the cam G and the plate F. vWhen the replacement magazine has been located on theplate F, the magazine is loweredonto itsbase frame by a return movement ofthe arm Kto its original inactive position, the operation `of the `interconnecting parts being the reverse of that just described. l. n

With the foregoing arrangement, `a 180rotation of the arm` K from inactive to active Vposition is utilized to effect the 90"v rotation of the shaft G1 y forcing bar on its under `surfaceridingdri the y angular relationship shown in Fig. 4. Such movein separating the magazine from its base frame,

thus obtaining a mechanical advantage. of two. Additional mechanicaladvantage is obtained because of the formation ofthe p1`at`e cam G. y Thus, the plate cam G is bentftransversely` to provide, at the bend, a portion g which, as the cam is rotated,

" rst engages the plate F. Asthe cam G continues v to use it as one of a pair of arms for supporting the magazines at the front of the machine during the removaland replacement operations. this end, the arm K is formed with a pair of ribs K3 and K1 projecting laterally different distances from its inner face the lower rib K4 projecting beyond the rib K3 (Fig.` 4). `The ribs K3 and K4 converge at the hub end of the arm K into `a single rib whose top surface lies slightly below the plane of the top surface of the plate VF when the latter is in its raised position. The upper rib K3 extends in the saune plane throughout the `length of the arm, terminating in an upturnjed lip K5. The rib K4, on the other hand, extends `in the same .direction as the rib K3 but diverges downwardlt7 therefrom, terminating short of the forward end of the arm K in an upturned lip K6` whose free end is sufficiently below the rib K3 so asnot to interfere with a .magazine supported on the latter rib. The companion arm K1 at the opposite side of the bank of magazines is With ribs K3 and K4.

i i The 'twopairs of ribs` K3 `andyl, adapt the 3,40 K3 thereof, where it is pivotally supported in aV identically formed I,arms K and K1 to support both full llengtlri maga-f zines1 aswell as the lower sections of the4 split variety of magazine, one-ofv which, as stated, is shown as the top magazine in Fig. 1. `flhus, in removing a full length magazine, such as the magazine shown in thefraised removal position in Fig. 4, the magazine is lifted by hand to disengage the front transverse rib azfrom the `stop `shoulder F3 at the forward end` of the plate F, freeing the magazineso that. it can move forward by gravity guided bythe central fore-and-aftreingroove F2 in the plate F.I f Asthemagazine slides forward olfv the plate F, therearmost transverse rib a2 thereof comes .to rest on the ribs K3 4and supports the magazine during the remainder of its `travel until the` rib aZ strikes the.rv lips K5, whence the magazine is .allowed-to pivot on .the rib `in, assuming avertical position fromrwhich it is manually lifted from `the arms K andK1.` 1 In thegreplgacement ofl aV magazine, the rearmost transverse` rib a2 of the magazine is set on the ribs K3 in back of the lips K5 with the magazine ina vertical position. p Then the magazine is tilted so that it lies substantially in the plane of the ribs K3 and the plate F and is forced rearwardll until itV reaches -a positionV where ltsforward end can be `lowered on to the plate Fwith the foremost transverse rib a2 thereof engaged behind the shoulder F3. 'I'he magazine is then in position to be lowered onto .its supporting base frame.

With the split variety of magazine, however, the rearmost transverse rib `d2 is not as long (due `to thedivergent shape of the magazines) as the rearmost transverse rib of a fulllength magazine. Hence, when the section a is 1removed. (inthe same manner as already set forth for a full length magazine) its rearmost rib a2 slides along the wider ribs K4 and comes to rest against the lips vertical .positionprior to being lifted from the armsKand K1. o

The magazine supporting arm K1,` at the right of the machine, is movable into andout of active position independently of the arm K. `As shown in-Figs. 5 andythe arm K1 is pivotally` mounted on a stub shaft K1 fastened by a nut `K8 tothe frame B so that, like the arm K, it extends rearwardly alongside the bank of magazines when in its inactive position* and is provided with `a handle K9 whereby it maybe rocked manually into and out of its forward active position. VBecause the right side of the magazines do not diverge` outwardly from front to rear to the same extent as the left side of the magazines (see the shape of the base frame inFig. 5), and also in order that the arm K1 will clear the` bankuof magazines when lin its inactive position and yet be in magazine supporting position when in `its active position, the arm K1 is fastened to the shaft K1 by` a screw K10 extending lthrough ya hub portion AK11 of the arm and having a reduced unthreaded end portion` K12 which projects -into axspiral groove K13`formed in the periphery of the shaft and eX- tending throughout one-half the circumference thereof (Fig. 6). Withthis arrangement, when the arm K1 is moved from the :full line position to the dottedline position in Fig; `5,\the screw K1o follows the spiral groove K13 and shiftsV the arm K1 as awhole inwardly or to the left toward the companion arm K, the screw K10 maintaining the arm K in `itsactiveposition by banking against the end of the slot K13. Likewise when the arm K1 is returned to its inactive position,.the end Aof the screw K10 followswthe groove K13 and shifts thearm'jas a "whole outwardly vor to the right,

A U-'shaped member/A8;-forjsupporting the magazine 'separating plateEfis arranged flatwise with its crossbar welded to the' underside of the rear 'bar `A6, its arms extending forwardly and being Welded to the center membersA". Hence, the baseframe is a lsimple built-up structure of light-weight steel structural elements which may be individually-machined, where machining is necessary, before fbeing assembled and welded into a unit.

The rear-bar A6 of the base frame is equipped at its opposite lends withthe pins A2, previously mentioned, which engage in notches formed in the side plates A3 to permit the pivotal movement of the base frame in the spreading of the magazines. A cut-out A15 is provided in the forward edge ofthe rear bar A6 to receive the aforementioned centrally located fore-and-aft reinforcing-bar on the underside of the magazine. The U-shaped vmember A8, which supports the rear end of the'y magazine separating plate F, has grooves A11i formed in the top surface of its two arms `to ,provide 'bearings'for'the pins F1 projectinglfrom opposite sides of the plate and which permit t1f1epivota1 movement of the plate in raisingand lowering the magazine. In order to provideI clearance for Athe plateF and cam G when in their inactive positions, so that the magazine `will rest on the side members A4 of the base frame, both thelfront and rear -walls of the channel member ,A5 are out away as at A1. v TwornembersA25 are Welded to the channel member A5 at its' opposite ends and extend forwardly therefrom, lbeing formed Aat their' iront ends withupstanding shoulders or lugs A10 adapted to engage theV forward edge 'o f the front magrazine cross'b'ar *a2 to hold'the magazine in position on the base frame. Avboss A11 is formed on the outer face vor" each of the members A25, and each boss vis drilledthrough froml top to bot'- tom and thre'aded' to accommodate banking screws A12 and A13 4for theadjustment and location ofthe baise frames to support the respective magazines in proper registry withthe assembling mechanism C when in operative position. As best shown lin Figs. l and 8, the banking screws A13 are threaded uptight against the bottom 'of the bosses\A11, whe'reas the screws'A12 in the respective base frames are threaded downwardly into the bossesthe screws A12 being long enough toextend above thertop of the magazines suppoted on said base'tframes into engagement with the banking screws' A13 of the base frame next above. The bankingscrews A12 are secured in their'positio-ns by adjusted lock nuts VA 14.- This arrangement eliminates all the machinin'g that otherwise would have to be performed on the lbase f ramesvthemselves were sur- ,faces thereonl lused in effecting the base frame adjustment.

It` willv now be apparentthatthe present -inl vention represents a -distinct advance over the construction of the present commercial machine. The improved base frame" is structurally amore simplied unit, and this, in addition to the fact that the elements are structural shapes, enables a reduction in 'the' weight of the base frame structure equal to approximately one-half `the weight 'of a, standard cast iron base frame. f Yet such reduction in weight carries with it no sacrifice in strength. 'I'he substantial reductionin the weight ocf the shift frame unit` has resulted in cutting down the time required for the magazine shifting operation due to the fact that the shift unit' lcan be accelerated and decelerated with `less effort and clash. Furthermore it permits a more satisfactory counterbalancing of the shift frame unit andv reduces the possibility of damage to the parts in the eventA something intervenes to obstruct its movement; Because of their size; the individual elements making up the improved basev frame are much easier to handle for machining and finishing, and should oneelement be accidentally rendered unusuable, that element alone is affected. Moreover, the individual elements,` and the base frame vas a whole, being made of steel, have more life and are tougher than the cast iron strutturev of theart. Whileit is preferred to use steel structural elements and weld them into a unitary structure, obviously the elements could be madeof otherma'terials or alloys having the desired characteristics of adequate strength and lightweight; and inany case, the elements could be joined together otherwise than by welding.

As regards the improved. magazine spreading and separating mechanisms, here again simplicity of design and construction are combined in providing for rapid and easy operation'. The magazine spreading mechanism is mounted in the machine frame as rotation of the magazine supporting arm to obtain the' increase in mechanical adthe art, and,`as `already stated, many variations and modifications, ofthe preferred embodiment of the invention shown in the accompanying drawings may be made which will still be -comprised within its spirit.` It is to be understood, therefore, that the invention is not to `be limited to anyparticular form or embodiment except insofar as such limitations are specified in the appended claims. t
