Application filed June 10, 1928. Serial No. 114,990.

The present invention relates to improvements in typographical machines of the class shown and described in U. S. Patent No. $36,532, granted Sept-ember 16,1890, employing cliaract-er-bearing matrices and expansible spacers which. by 1 appropriate mechanism, are drawn from their magazines or places of storage and assembled into a line. the line is justified and a cast is taken therefrom to produce a type bar or slug, after which the matrices and spacers used in the line are returned to the magazines or their places of storage. lates more particularly to machines of this general class which are adapted for the as semblmg of matrices belonging to differenttouts as the nature of the composition may require, for which purpose it is preferable to employ a plurality of superposed magazinesto'contain the diflerent fonts ot matrices, and to provide meansjfor shifting the magazines to bring one or another thereof into position to deliver the desired matrices for assembly into the line and to receive such matrices which are returned thereto after a cast has been made from the matrix line.

One of theobjects of the present invention is to provide improved means whereby the shifting mechanism and the operative support for the magazines constitute parts of the main frame of the machine, thereby insuring permanency and stability in theshitting movements and the positioning of the magazines and the maintenace of the correct working relationship of each of the magazines with the coopcratlng mechanisms of" the machine. the weight otthe )arts which require shitting being also reduced so that the shiftinn of the magazines may he accomplished with greater ease and facility. 7

Another object of the invention is to provide a novel and improved multiple maogazine unit and mechanism v tor shitting itwhereby the weight of the mag'azine'unit is "so balanced as to enable itto be easily shifted to bring the difl'erent magazines into position for operation or rocked to carry the magazines into position tor removal and.

"mor over. the shifting: movements of the magazines may be caused to take place in such a manner as to equalize or distribute the load and thereby enable the magazineslittingoperations to be performed \vithless e ort.

The invention re- 7 Another object of the invention is to provide means for so coordinating the lifting and travelling movement of the forward ends of the magazines during shitting thereof as to insure clearance between the magazines and the upper-ends of the reeds or escapement actuating devices during each magazine shitting operation.

A further ,object'of the invention is to provide means which locksor holds the magazines in their respective operative posit-ions when they have been brought into suchvpositions. thereby preventing accidental displacement of a magazine from its operative position after it has been brought into such position although permitting the magazineshifting mechanism to be operated to remove a magazine from operative position and to bring another magazine into such position when such is desired.

To these and other ends, the invention consists in certain improvements and combinations and arrangements of parts, all as will be hereinafter more fully described, the

features of novelty being pointed out partionfshowing the manner of mounting one side of the magazine unit onthe main frame otthe machine; Figure 3. is a detail view in side elevation and on an enlarged scale. of the magazine unit and its support. this view illustrating diagrammatically the movement of the magazine unit while it is heme; shifted to re move one magazine from operative position and to bring another magazine into such position;

Similar parts are designated by the same reference characters in the several figures.

The present invention is applicable generally to typographical machines of the class shown and described in the patent hereinbefore referred to, although it is particularly applicable to machines of this class which are adapted to contain a plurality of superposed magazines containing different fonts of matrices which are capable of being assembled in a line as the nature of the matter in course of composition may demand. The preferred embodiments of the invention are shown in the accompanying drawings and will be hereinafter described in detail, but

it is to be understood that the invention is not restrictedto the precise construction shown as the scopeof the invention is indicated by the claims.

In the present instance, the machine, which may be in generalof the class shown and described in said Letters Patent, is adapted to contain three superposed magazines designated 10, although the unit may contain a greater or less number. of magazines. Each magazine may be of the construction usual in machines of thisgeneral class and may contain" any desired font of matrices, the lower ends of the magazines being equipped with escapements 10-which serve to retain the the matrices therein although effecting delivery. of matrices when actuated by the usual keyboard mechanism of, themachine to .which the escapements. are operatively I relatedwhen themagazine is in operative position. Each magazine is mounted on a magazine frame 11, theseframes supporting the respective magazines and preventing them from sliding forwardwhen the magazines are in their normal forwardly and downwardly inclined positiondas shown by thefull linesin Figure .1, but permitting any one or'more of the magazines to be removed therefrom by sliding such magazine or magazines rearwardly while the magazine unit is rocked into a rearwardly and down wardly inclined position, as indicated by the dotted lines in Figure 1. Side plates 11 are secured to the opposite side edges of the magazine frames 11, a multiple magazine unit being thus formed which comprises the magazines 10 and their frames 11.

The magazine unit just described is operatively supported in the machine by a pair of side brackets 12 and 13, these side brackets being secured to and constituting parts of the main frame of the machine. In machines of this general class, the main frame is usually composed of a number of separate parts or components which are secured to one another to form a rigid supporting structure. For example, the distributor bracket 15 commonly used on machines of this class to support the distributor mechanism, the intermediate bracket 16 which supports the keyboard mechanism of the machine, and the bracket 17 which forms a tie between the brackets 15 and 16 are bolted together and form parts or components of the main frame, and in the construction illustrated in Figures 1 and 3. the front portion of the bracket 12 is secured to the intermediate bracket 16 by a bolt 20 while the rear portion of the backet 12 is provided with a laterally extending stud or trunnion 21 which is secured permanently thereto or is formed integrally therewith, this stud engaging in an aperture 22 which is formed in an arm 23 which is a part of the distributor bracket. The bracket 13 is secured at its forward end to the column 18 which is a permanent and rigid part of the machine frame. by the bolt 21, and this bracket 13 is provided at its rear portion with a laterally extending stud 25 which is secured permanently thereto or is formed integrally therewith, this stud engaging in an aperture 26 formed in the distributor bi acket 15. Thus the brackets 12 and 13 which serve to support the magazine unit become permanent or. fixed components, of the main frame of the machine when they, are securedin place.

A shaft 30 is journaled to or extends transversely through the intermediate magazine frame 11 and this shaft has rollers 31 ournaled thereon at the opposite sides of said frame, as is shown in Figure 5. The ends of the shaft. 30 are 'fitted into the upper ends of a pair of links 32, they being fixed to the links by the pins shown or other suitable means, the lower ends of the links being operatively connected with the magazine shifting mechanism as will be hereinafter set forth. Thc

rollers 31 are guided and supported by inclined rails 33 which are formed on the upper portions of the side brackets 12 and 13, the rollers being adapted to ride upon these rails during the shifting movements of the magazine unit, whereby the shaft 30 which pivotally supports the upper portion of the magazine unit is guided to move rectilinearly in a forward or rearward direction with respect to the main frame Inn ' serve as rails.

" of these slots.

The shifting mechanism for the magazine unit is supported to travel on the rail surfaces 36 and such shifting mechanism co.- operates with the racks 35 and with the links 32. The shifting mechanism as shown comprises a pair of pinions 40 which are located at the inner sides of the frames 12 and 13.

and are fixed to shafts 41 which extend out wardly through the slots 34 in these frames, the pinions meshing with the racks 35 which are fixed to the respective side frames. Anti-friction rollers 42 are preferably mounted on-the shafts 41'so that they fit the slots 34' in the side frames and ride upon the rails 36 formed at the lower edges The shafts '41 are connected by a shaft 43 which is located eccentrically of the shafts 41, the latter shafts having their centers in alinement. As shown, the ends of the shaft 43 are rigidly fixed to the inner ends of the shafts 41 by cranks 44 and-45. The shaft 43 extends across the space between the inner ends of the shafts 41 and has anti-friction rollers 46 journaled thereon, these rollers being arranged to ride against the'surface 46 which is formed at the forward under side of the lower maga zine frame 11, this surface being preferably inclined substantially at the angle shown. The magazine shiftingmechanism is operated by a crank or handle 47 which is fixed to the outer end of one of the shafts 41', it being preferably fixed to the right-hand shaft for convenience of operation. The shafts 41 in the preferred construction are provided at the outer sides of the frames 12 and 13, with eccentrics-48giwhich are fixed to these shafts by the pins 49 or other suit able means, the centers of these eccentrics being preferably located in a line between the centers of the

shafts

41 and 43 so that these eccentrics and theshaft 43 are offset at substantially the same angle with respect to the shafts 41. The lower ends of the links 32are formed as hearings or straps which fit the respective eccentrics 48. It will be observed that themagazine-shifting mechanism just described embodies a double eccentric mechanism which comprises the shaft 43 which is eccentric to the shafts 41 and the link-operating eccentrics 48 which are also eccentric with respect to the shafts,

In. order to insure proper registration of the lower end of each magazine with the matrix assembler entrance 55 and the upper endof the magazine with the channel entrance 56 which leads from the matrix distributor, when any one ofthe magazines is brought into operative position, the side plates 11 toward the lower forward end of the; magazine unit are provided with suitably positioned lugs 57 which project outwardly therefrom and the side frames 12'and 13 which are spaced apart sufficiently to permit these lugs to pass between them are provided with inwardly opposite formed with suitably positioned recesses 58 arranged inthe path of the lugs, these lugs and recesses being so located that a pair of lugs-011 the magazine unit williengage the recesses 58 in the side frames as each magazine in the unit approaches the work mg or. operative position, these lugs and recesses thus servmg to insure proper position of the lower and upper ends of the:

magazine thus brought into operative position with respect to the assembler entrance and channel entrance. 7

In assembling magazine supporting and shifting means constructed as hereinbefore described, the brackets 12 and 13are first placed between the arms ofthe distributor bracket 15 so that the studs 21 and 25 on these brackets will enter the apertures 22 and 26 in the distributor bracket, after which the side frames 12 and 13 are moved 21. and. 25 in said apertures. The forward end of the bracket 12 comes against the adjacent side of the bracket 16 to..which it is secured byinsertion ofthebolt- 20 and the forward end ofr-the bracket 13 fits against the column, 18 to whichit is secured by insertion of the bolt 24. If desired, the studs 21 and 25 maybe locked in the respective apertures in the distributor bracket by. the insertion and tightening of the set screws 59 carried by the distributor bracket. the side brackets 12and 13 are mounted, they are rigidly secured to the main frame and become parts or components thereof. After thesebrackets have been mounted, the magazines, magazine frames, the magazine supporting shaft 30 and its rollers a-ndlinks, and the magazine shifting mechanism may lVhen portions laterally outwardly to fully insert the studs be separately positioned and assembled to shift the'unit to bring the intermediate or the lower magazine into operative position,

this shifting operation is effected by turning the handle 47 in an anticlockwise direction, as viewed in Figure 1, through one or two revolutions, according to which magazine is to be brought into position for use. Turning of the handle 47 effects rotation of the shafts 41, and as the pinions 40 are fixed to these shafts, the pinions will rotate and, in so do ing, they will travel forwardly on the 'acks with which they engage. The shaft 43 which is fixed to the shafts 41 in eccentric relation thereto will, as a result ofthe rotating and traversing movement of the pinions, swing through an approximately cycloidal path. While a magazine is in operative position, its escapements are located unit.

immediately above and in operative relation with the upper ends'of the reeds or escapement actuating members which are carried by the bracket 16 of the main frame,

butwhen the crank 47 is rotatedin the manner stated, the rollers 46 on the eccentric shaft 43 and which bear against the surfaces 46 on the lower magazine frame act to lift the lower or forward end of the magazine unit, the rollers 46'riding on the surfaces 46while the pinions move forwardly on their racks. The lifting movement thus imparted to the magazine unit causes'the lower end of the magazine which was in operative position to be lifted so that its escapements are carried upwardly and away from the actuating reeds. The movement of the magazine unit in a forward and rearward direction is controlled by the links 32, thelower ends'of which cooperate with the eccentrics 48 fixed to the shafts 41 and the upper ends of which are fixed to the transverse shaft 30 which supports the magazine The shiftable bearing or engagement of theshaft 43 on the surface 46 of the magazine unit enables ample lifting and lowering movements of the matrix-delivery end of the magazine unit to be derived from the cycloidal motion of this shaft, but as the center of this shaft is outside the pitch circles of the pinions 41. it will travel in a cnrtate cycloid, and if this shaft had a fixed bearing on the magazine unit, the latter would receive a reverse movement before commencing would otherwise receive and to enable the forward and rearward shifting movements of the magazine unit, incident to its removal from one operative position and its placing in another position, to be ell'ected by other means which acts for example through the links 32 connected to the rollers 31 which shiftably support the upper end of the magazine unit.

It has been found that if the shaft 30 supporting the magazine unit is arranged to move forwardly or rearwardly in unisonor synchronism with the shafts 41 during the shifting operation, the rezulting longitudinal movement of the magazines will be rapid with respect to the lifting action ofthe shaft 43 and it might tend to cause the lower ends of the magazines to collide with the upper ends of the reeds. However, by connecting the shaft 30 to the shafts 41 through eccentrics on the shafts 41, as in the preferred construction hereinhefore described, a variable longitudinal movement of the shaft 30 with respect to that of the shafts 41 is obtained during the shifting of the. magazines, and by the use of eccentrics the centers of which are on or within the pitch circles of the pinions 40, so that the eccentric centers will describe common or prolate cycloids during the forward and rearward travel of the pinions, the forward and rearward shifting movements of the magazine unit can. be most advantageously coordinated to the lifting and lowering movements of its matrix-delivery end.

Figure 6 shows diagrammatically the differential longitudinal movement of the shaft 30 relatively tothe shafts ll during the shift'mg operation obtained from eccentrics whose common center 71 is located within the common pitch circle of the pinions 4t), and which are connected to the shaft 30 by links 32. In this figure, the lines 61 and (32 represent, respectively, units of longitudinal movement of the

shafts

30 and 41, these lines being provided with graduation; reading from 0 to 12. The forward and rearward traversing movements of the shafts 41 are regular and in direct proportion to the rotation of the operating handle and, hence, the graduations on the line 2 are spaced uniformly, whereas the forward or rearward movement of the shaft 30 is variable with respect to the forward or rearward movement of the shafts 41 and, hence, the graduations on the line (31 ,vary or are unequal. Asiauming that the point 0 on the line 61 coincides with the center of the shaft: 30 and that the 0 on the line 62 coincides with the center of the shafts 41 before the shifting operation commences, then the first part of the rotation of the operating handle will rotate the pinions in thcdirection of the arrow C. and while the center 70 of the shafts 41 is moving forwardly from 0 to 1 on the line (52, the center of the shaft 30 will move forwardly through the, much shorter distance represented between 0 and 1 on the line 61. During this rotation of the shaft l1, the shaft 43is aoting to lift the forward endsof the magazines and the relatively small forward movements of the magazines at this phase.

of the operation enables the eseapeinents to be di.:;.engaged from the reeds by movement of the escapements in a direction which is approximately vertical. As the rotation of the shafts ll continues under the motioiiiinparted thereto by the operatinghandle, the

center 70 ofytheshafts 41 travels along'the line 62. from the point 1 to the point 2? and during this advance of the shafts 41 the eccentric shaft43 acts to further lift the forward ends of the magazines while at the same time the center of the shaft moves forwardly along the lines .61 from the point 17? 2 on the line 61 isymuch less thanthat along the line between the g raduations 1 and 2; althoaghtheunit of movement beween the gradnations 1 and Q is somewhat greater than that be ween the graduations O and l on the line 61, and, hence, the forward movement of the magazines at this phase in the peration is relatively small in comparison with the lifting movement of the shaft As the shifting ing spacing of the graduations along the line 61. By retarding the forward movement of the shaft 80 during the initial and final stages of the shiftingoperation, the eccentric shaft 413' is enabled to operate effectively to lift the escapements of the magazine previously in use out of working relation with the reeds and to lower the escapements of another magazine brought into use so that they will be in working relation Wltlr the reeds, without danger OffCOlllSlOll between the escapeiiients or the lower ends of the magazines with the reeds. Furthermore; by imparting an, accelerated forward move-J ment to the shaft 3-0 at the intermediate stage of the shifting operation, the maga zine previously in use, after it has been elevated. will be shifted rapidly out of work ing position and the next magazine will be shifted by a rapid movement to bring its escapements into positionabove the reeds.

The differential traversingmovement im-,

thereon to the point 2. The unitofl movement between the graduatioiis flhand parted to the shaft 30 from the shaftsl, through the eccentrics on the latter: shafts and the links, not onlyfacilitates the move- "ment of one magazine out of operative position and the moving of another magazine into operative position with respect to the escapeineiit actuating reeds,.butit also enables the'shiftingopei'ation to be performed with greater ease by equalizing or distributing the load throughout the entire shifting operation. It will be noted that while the weight of the lower ends of the magazines is being lifted by the upward movement of the shaft 43, there is a relatively small longi tudinal movement of the shaft 30, but after the lower ends of the magazines have been elevated and no further energy is required for the'elevating operation, the shaft 30, will travel at an accelerated speedto carry the magazine unit forwardly or rearwardly,

andthis increased rate of movement of the magazine unit in a forward or rearward (11-. rectiondoes IlOt'lIDPOSG any additionalload upon the operating crank asno further -lifting of the forward ends of the magazines is required at this stage. a

Figure 3 shows in full lines the magazine unit at thestage in the shifting operation where the lower ends of themagazines have been elevated to approximately their highest point, and the dotted lines in this figure indicate the position finally assumed by the intermediate magazine asit moves into 0perative position, the accelerated longitudinal movement of the magazines beginning as the.

shiftingniechanism moves from the full line position toward the dotted line position. Accurate positioning of the different magazines relatively to the assembler entrance .55 and the channel entrance 56 is insured by the lugs 57 which are positioned on the inagazine unit to conform with the operative po sitions of the different magazines and are arranged to rest in the recesses 58 in the side brackets 12 and. 13 when the respective magazineqis inoperative position. The dotand-dash line X indicates substantially the path through which these lugs travel in moving to .and from engagement with the recesses 58 when the forward and rearward shifting movements of the magazine unit are governed by the eccentrics 4:8, as hereinbefore =described.

The double eccentric arrangement provideclin the shifting mechanism not only controls the for-ward or rearward movement of the magazine unit during the shifting'thereof to facilitate the removal of one magazine froinoperative position and the bringing of another magazine into such position, butv it also provides a looking or holding means vliich will prevent accidental displacement of a magazine from operative position- This will be understood from Figure 6 which diagrammatically represents the position of the partsiof the shift-ing' mechanism when a magazine is in operative position. In this figure 70 representsthe center of the pinion 32 which would tend to move its lower end forwardly or in the direction of the arrow B. -However, at this time, the center 71 of the'eccentric engaged by the lower end of thelink occupies a position between the center 70 of the pinion and the rack. The pin ion will then be locked against forward movement alongits' rack because forward movement of the pinion along its rack would involve rotation of this pinion in the direction-of the arrow C and the consequent motion of the center 71 of the eccentric in the salnedireotlon would oppose and overcome the forceactingon the link 32 in a direction to move it in the direction of the line B.

Similarly, if a force acted on the magazine unit in a direction to move the shaft 30 rearwardly or in the direction of-the arrow D in Figure 6, a resultant upward pull would be exertedon the link 32. This force would be transferred from the link through the eccentric to the pinion and would act to move the pinion rearwardly or in the direction of the arrow E. Such rearward movement of the pinion, however, would require rotation of the pinion in the'direction of the arrow F and, in consequence, the shifting mechanism would look the magazine unit against such movement. It will, therefore, be understood-that'while a magazine is in operative )osition, it cannot be displaced accidentally from such position by a force acting to move the magazine unit either forwardly or rearwardly, but the magazine unit may be promptly shifted to carry one magazine out of operative position and to bring another magazine into such position, by mere rotation of the operating handle in the appropriate direction and through the appropriate number of revolutions. If the upper magazine isin operative position and it is desired to bring the intermediate magazine into such position, one complete rotation of the operating handle 47 in an anti-clockwise direction as viewed in Figure 1 will effect this shift; and if it is desired to remove the up per magazine from operative position and to bring the lowermost magazine into such position, two revolutions of the operating handle 47 in an anti-clockwise direction as viewed in Figure 1 will effect this result. If the intermediate or lower magazine occupies the operative position and it is desired to bring the upper magazine into such position,the shift is made by turning the operating handle 17 in a clockwise direction through one of two revolutions, as the case may be. 7

When it is desired to remove a magazine from the magazine unit and replace it by another magazine, it is only necessary for the operator to grasp and pull downwardly on the 'handle 14: which is attached to the rear end of the lower magazine frame. The magazine unit will then be rocked from its normal forwardly and downwardly inclined position into a reverse or rearwardly and downwardly inclined position, the rocking motion taking place about the shaft 30 as a center, and durmg this rocking movement the surface 46 on the lower magazine frame merely lifts out of working relation with the rollers 46 on the shaft 43. Figure 1 shows the magazine unit shifted into its rearwardly and downwardly inclined position by the dotted lines, the magazine unit being thenin a position which enables any one or more of the magazines to be removed therefrom and otherssubstituted, after which the magazine unit may be returned to its normal position as shown by the full lines in this figure, the surface 46 on the lower magazine frame being thus restored to its normal working relation with the rollers 16 on the shaft 43. In order to hold the magazine unit in its magazine removing position, as shown by the dotted lines in Figure 1, a gravity latch 19 may be pivoted on the lower magazine frame and shaped and arranged to latch over a flange on the distributor bracket when the magazine unit has reached the proper tilted position, the latch holding the magazine unit in such position until the magazines have been changed as desired, whereupon releasing of the latch 19 from the distributor bracket will enable the magazine unit to tilt back to its normal position. The weight is so distributed in the magazine unit that the portion thereof forward of the shaft 30 is heavier than its portion in rear of said shaft so that the magazine unit by its own weight will tend to remain in its normal forwardly and downwardly inclined position and the surface 46 on the lower magazine frame will remain in contact with the anti-friction rollers 46 on the lifting shaft 43.

The modification illustrated in Figures 7 and 8 is applicable to the usual components of the main frame of the machine, as previously described, but the rails 33 on which the rollers which support the magazine unit ride are formed on brackets which are cast as integral parts of the distributor bracket 5, and the rail slot 34 in which the shafts 41 of the shifting mechanism operate is formed in a bracket 17 which is cast as an integral part of the usual tie bracket 17. The supporting and shifting mechanism may be applied to this embodiment substantially as has been described in connection with Fig ures 1 to 6, inclusive.

In the modification shown in Figure 9, a bracket 12 is used which is secured at its rear end to the distributor bracket by bolts 21 or other suitable means, and it is secured at its forward end to the intermediate bracket 16 by a bolt 20; This bracket 12* is formed on its upper edge with a rail 33* on which may ride the roller on the corresponding end of the shaft 80, and this bracket is also formed with the rail slot 34; in which the shaft 41 of the shifting mechanism operates. The supporting and shifting mechanism may be applied to this em bodiment in substantially the samemanner as has been described and the mode of operation is identical therewith.
