TYPOGRAPHICAL MACHINE (CHANNEL ENTRANCE).

Application filed July 1, 1926. Serial No. 119,985.

T he present invention relates to improvements in typographical machines of the general class shown and described in U. S. Letters Patent No. 436,532, granted September 16, 1890, and it is more particularly applicable to machines of this general class which are constructed to hold two or more magazines which may contain, respectively, matrices belonging to different fonts or matrices having different kinds or styles oi type faces, and from which magazine mat rices may be drawn as desired and ass-rm bled to form a line of mixed matrices from which type bars or slugs may be cast, machines o'l this class being known as 01 the mixer type. The invention relates especially to machines oi? this type in which the magazines are mounted to rock or tilt rearwardly in order to permit removal ol the magazines at the rear of the machine, and in which channel entrances are positioned lrelwccn the magazines and the distributor mechanism. when the n'iagazines are in their normal or operative position, to guide the matrices returning from the casting mechanism from the distributor mechanism to the magazines.

In machines of this type, the upper portion of the channel entrance must be positioned at a predetermined distance below the distributor screws, and the lower portion oi the. channel entrance must engage am:

tcr with the upper rear ends of the magazines when the latter are in their normal forwardly and downwardly inclined position. ll hen it is desired to tilt the mriqazines rearwardly for magazine removal or to examine the distributingmechanism or the interior of the channel entrance, it is necessary to first move the channel entrance from its normal position, but since the upper terminals of the channel entrance, when the latter is in its normal position, is disposed immediately adjacent to the lower distrihutor screws, it has heretofore been difficult to remove the entrance without interterence "from other parts or mechanisms of the machine, because the entrance must first be moved sharply downwardly to avoid striking the lower distributor screws, and the entrance must immediately thereafter move rearwardly away from the magazines in order that the magazines may clear the entrance when they are rocked or tilted rearwardly and downwardly to bring them into inacazine-removing position.

The primary object of the present invention is to provide a novel and improved channel entrance and mounting therefor which O'VQlQOlllGS the difliculties or objections which have been experienced with channel entrances which have been heretofore used on machines containing rearwardly tiltable magazines, the channel entrance and its mounting, according to the present invention, enabling the channel entrance to be easily and quickly moved out of its operative position without interference from or interfering with the distributor screws. ant then movable out of the path of the upper ends ot the magazines so that the latter may be swung or rocked rearwardly without in tericrence 'lrom the channel entrance; or the channel entrance may be easily and quickly removed from its operative position to a position which enables the distributor mechanism or the channel entrance to be inspected or renders the distributing mechanism and the channel entrance accessible, for removal of obstructing matrices, repair or other purposes.

Another object of the invention is to provide a novel and improved channel entrance and mounting therefor, together with means which enables the channel entrance to be easily and quickly moved from its operative position to one position which enables the magazines to be swung rearwardly to magazine removing position and which enables the channel entrance to be moved, when desired, to a second position which ailords easier access to the distributing mechanism and the assembler entrance and will effect removal of any matrices that may clog the channel entrance, a simple controlling device being provided which determines which of these positions will be assumed by the channel entrance vhen it is moved from its normal operative position.

Another object of the invention is to provide a composite frame which constitutes the mounting for the channel entrance whereby the desired movements are ob tained, together with means which serves to counter-balance the channel entrance and its mounting and to normally hold the components of the mounting in proper relationship when the channel entrance occupies its ill) operative position, thereby enabling the channel entrance to be manipulated with ease, speed and facility.

To these and other ends, the invention consists in certain improvements and coinbinations and arrangements of parts, all will be hereinafter more fully described, the features of novelty being pointed out particularly in the claims at the end of the specification.

The preferred embodiments of the 1nvention are shown in the accompanying drawings, wherein Figure 1 is a side elevation of the upper portion of a typographical machine of the type hereinbefore referred to and to wh ch the present invention is applied, parts being broken away or shown in section.

Figure 2 is a side elevation, partly in section, of the improved channel entrance and its mounting, the dotted lines showing the position of the upper end of the channel entrance relative to the distributing mechanism when the entrance is in its normal operative posit-ion and the full lines showing the position into which the entrance is first moved to remove it from operative position.

Figure 3 is a view similar to Figure 2, the channel entrance and its mounting being shown, however, shifted from the position shown by the full lines in Figure 2 to one of its inoperative positions shown by the full lines in Figure 3.

Figure at is a fragmentary view showing a portion of the channel entrance mounting and its support, the channel entrance being shown shifted to another inoperative position which it may assume.

Figure 5 is a rear elevation of the upper portion of a typographical machine of the class l'iereinbefore referred to but having an auxiliary or side magazine unit combined therewith, the improved channel entrance and mounting embodying the present invention being shown applied to both the main and side units of the machine.

Figure 6 a detail sectional view, the section being taken on the line 6--l of Figure 5.

Figure 7 is a detail sectional view, the section being taken on the line 7-7 of Figure Figure 8 is a detail sectional View, the section being taken on the line 88 of liigurn In the embodiments of the invention shown in the accompanying drawings, 10 designates the distributor bracket and 11 designates the usual distributor bar to which the usual distributor rails are attached and 12 desig ates the distributor screws which operate upon the matrices to advance them along the distributor rails while suspended therefrom until they reach their appropriate channe s in the magazines, as is well und rstood in this art. The distributor partly shown is of the double type to enable matrices belonging to two or more magazines to be distributed thereto. In the present instance, two magazines, l3 and 14, are supported in superposed relation on a frame or cradle 1.5, the magazines being shown in Figure 1 in their normal forwardly and downwardly inclined operative position. The distributor brackets carry or have fixed thereto brackets 17 and 18 which serve to support the channel entrance or entrances, these brackets being shown secured to the distributor bracket by screws 19. These brackets 17 and 18 are provided with bearings 20 in which the channel entrance mounting is supported.

A pair of channel entrances 24 and are provided for guiding the matrices from the distributing mechanism to the respective magazines l3 and 14, the channel entrances containing partitions 26 which receive the matrices between them and maintain them in upright position while descending through these entrances.

As shown by the full lines in Fig. l and the dotted lines in Fig. 2, the upper ends of the entrances, when in operative position, project upwardly above the bottoms of the lower distributor screws, and in order to secure a downward movement of the entrances which will insure clearance between their upper ends and the distributing mechanism when the entrances are swung rearwarilly or into inoperative position, a composite mounting is provided which comprises pivotally connected frame members 27 and 28, The frame member 28 comprises links which are suitably spaced and provided with pivots 29 which engage in the bearings 20 in the stationary brackets. 17 and 18. The composite mounting of the channel entrances is adapted to swing as a. whole about the pivots 29, and in order that this niovemei'it of the channel entrances may be rearwardly and then downwardly, the pivots 29 are located approximately directly below the distributing mechanism. The frame 27 is pivoted on the frame 28 so that these frames may have a relative 'iivoting n'loven'ient. As shown, the frame 27 is provided at its sides with pivots 30 which engage in bearings 31 formed in the links comprising the frame 28. The frame 27 rocks or swings on the centers of the pins 30 during the movement of the channel entrances which lowers them from operative relation with the distributing mechanism, and in order to secure a sharp downward movement of the channel entrances which will avoid interfering with or interference from the i tributor mechanism. the pivots 30 and their oearings Ell are located forwardly of the pivots 29 about which the channel entrance mounting as a whole swings, and preferably Inn Ill)

the pivots 30 and their bearings 31 are located in a vertical plane which is forward of the distributing mechanism whereby the upper ends of the channel entrances in swinging from their normal operative position shown by the dotted lines in Fig. 2 to the full line position shown in that figure will describe the are T which clears the lower rear distributor screw. The frame 27 preferably embodies end members 32 and 33 which are rigidly connected by a longitudinal rail or brace 34. Adjustable screws are tln'eaded into the forward upper ends of the links and the heads of these screws form abutments on which the forward ends of the end members 32 and 38 of the framemember 27 may come to rest, thus limiting the forward swing of the frame member 27 about the pins 30 as centers. These set screws may be locked in adjusted position by jamb nuts 41. The rear upper ends of the links 28 comprising the lower frame are formed with abutment surfaces 42 which are adapted to be engaged by the abutment surfaces 43 on the end members 82 and 33 of the frame 27, thus limiting the downward and rearward swing of the frame 27 as shown by Fig. 2 wherein the abutment surfaces 32 and 43 are in engagement. 7

The channel entrances are so mounted in the frame member 27 as to enable them to accommodate themselves to the positions occupied by the upper ends of the magazines to which they pertain. For this purpose,

' the end members 32 and 33 of the frame 27 are formed with upwardly extending arms 45 and these arn'is are provided with apertures 46 in which are fitted alined pivots 47 and 48, as shown in Fig. 5. The pivot member 47, as shown in Fig. 6, is secured against longitudinal displacement from the finger 45 by a set screw 49 which is threaded into the arm and engages at its inner end in an annular groove 47 a which is formed at the middle of the pivot member 47. Bars 50 and 51 are secured to therear walls of the channel entrances 24 and 25, respectively, and these bars are connected to the pivot members 47 and 48 by arms 52 and 53 which are attached to the bars 50 and 51, respectively. The pivot-engaging ends of the arms 52 and 53 are preferably formed with hooks 54 and 55, respectively, the. hooks 54 on the bar 50 engaging the inner ends of the pivots 47 and 48 and the hooks 55 on the bar 51 engaging the outer ends of the pivots 47 and 48. The pivot 47 is preferably threaded while the pivot 48 may be unthreaded, and the hook threaded on the inner threaded portion of the pivot 47 so that rotation of this pivot will adjust the hooks 54 axially on the pivots 47 and 48. Also, the pivot 47 has a threaded engagement with an adjusting sleeve 56 which has a grooved periphery to receive the hook 55 whereby the hooks 55 may be adjusted axially of the pivots 47 and 48. By this construction, the channel entrances are pivotally secured to the frame 27 so that the forward ends of the channel entrances may rock and thus accommodate themselves to the vertical positions of the upper ends of the respective magazines, and also the channel entrances may be adjusted laterally and individually in the frame 27 to insure proper lateral registration between the entrances and the respective magazines.

The channel entrances are reinforced by bars 60 and 61, which are secured to their rear walls toward the forward ends thereof. The ends of these bars extend outwardly beyond the sides of the respective channel entrances and are positioned between abutment surfaces or stops 62 and 63 which are formed on the end members and 33 of the frame 27, these abutment surfaces or steps limiting the pivotal movements of the channel entrances about the pivot members 47 and 48. The ends of the bar 60 are pressed upwardly against the abutting surfaces 63, while the entrances are removed from operative position by compression springs (34 which are located in the end members and beneath the bar (50, but the ends of the rail (3i will rest by gravity on the lower abutment surfaces ('32 when the upper channel entrance is removed from operative relation with its magazine.

In order to hold the channel entrances and their mounting in operative position and to counter-balance the weight of these parts and thus facilitate manipulation thereof, tension springs 65 are provided, these springs being attached at one end to sleeves (36 swivelled on the screws 66 on the frame 27 and to sleeves 67 swivelled on the screws (57 on the distributor bracket 10. These springs act to move the channel entrances into operative position and to maintain them in normal operative relation with their magazines. The screws 66 and 67 to which the springs are attached are out of line with and above the pivots 30 when the channel entrances are in or near operative position, as will be understood from Figs. 1 and 2, and these springs will, therefore, act to swing the frame 27 upwardly and forwardly about the pivots 30, thus carrying the forward ends of the channel entrances toward the upper ends of the magazines until such motion is arrested by the engagement of the frame 27 with the limit or stop screws 40. Also, these springs act on a line which is above the pivots 29 of the frame 28, and, hence, they tend to swing the frame 28 forwardly about the pivots 29, as will be clear from Figs. 2 and The springs, therefore, tend to swing the frame 28 from its rearward position shown in Fig. 3 to its forward position shown in Fig. 2, and in order to arrest the forward motion of the frame 28, the brackets 17 and ill) til

18 are provided with adjustable set screws or limit stops cs against which the under sides oi the links comprising the frame 28 are adapted to abut. These set screws may be locked in appropriately adjusted positions by jamb nuts 69.

In order to insure proper registration be tween the forward end of the channel entrance 25 and the upper end of its magazine this channel entrance is swung into operative position. guide lingers 71) are socured to the opposite ends of the reinforcing bar (ii on this channel entrance. these lingers being provided with bevelled surfaces 71 which are adapted to engage the upper surface oi the magizine 14 and ride upon such surface while the channel entrance 25 is moving into operative relation with its magazine,these guide fingers thus insuring proper vertical registration between this channel entrance and its magazine. Also, to insure proper vertical registration between the lower channel entrance 24: and its magazine 13, a guide lip 72 is secured to the rear wall of the channel entrance 2% and projects forwardly beyond the front end of this channel entrance, this guide lip being adapted to engage the lower surface of the lower magazine 13 as the channel entrance is moving into operative position. The bar 61. of the upper channel entrance 25 rests on the surface 62 by gravity and the bar of the lower channel entrance is pressed against the upper surface 63 by the spring 64 while the channel entrances are removed from operative position, as will be clear from Fig. 2, but as the guide fingers ride upon the upper surface of the respective magazine, during the swing of the upper channel entrance into operative position, the bar ('31 will be free to rise from the surface 62 under the control of the guide fingers 70; and also, as the guide lip 72 on the lower channel entrance abuts against the under side of the magazine 13 during the movement of this channel. entrance into operative position, the bar 60 on the lower channel entrance may be retracted from the abutmentsurface 63 against the action of the spring 6 1- under control of the guide lip 72.

Means is provided whereby the channel entrances and their mounting may be swung into either of two inoperative positions, at will. To secure this result, a stop 7 5 is provided, this stop being pivoted on a screw or other suitable pivot 76 attached to the "frame member 17 and having a finger-piece 7 8 by means of which it may be swung by hand to occupy either the full or dotted line position shown in Figure 5. The stop has a lug 79 thereon which is adapted to rest on the surface 80 on the frame member 17 when the stop is in its full line position. and the lug 79 will then be in a position to be engaged by the abutment surface 81 on the rear of the adjacent link of the frame 28. With the stop in this position rearward swing of the entrances and their mounting will be arrested when the parts reach the position shown by the full lines in Figure 3, this movement taking place about the pivots 29 so that the upper portion of the channel entrances swings through the arc U, Fig. As the upper end of the magazine 12-5 in swinging rearwardly about the pivot 16 moves through the are I, Figure 3, it will be clear that when the entrances and their mounting have been swung to the position shown in Figure 3, they will clear the upper ends of the magazines when the latter are swung rearwardly into magazine removing position, and vice versa. However, when it is desired to secure greater access to the dis tributing mechanism or the channel entrances, or to discharge any matrices that may have clogged vithin the channel entrances, or either of them, the stop is swung into the dotted line position shown in Figure 5 before the channel entrances are swung to inoperative position, and then the rearward and downward swing of the channel entrances and their mountings to inoperative position may continue past the full line position shown in Figure 3 to the position shown in Figure 4; as the movement of the channel entrances and their mounting is then not arrested until the abutment surface 81 on the lrame 28 reaches the abutment surtlace on the t'ran'ie member 17. When the channel entrances reach the position shown in Figure 4-, the distributing mechanism and the channel entrances are easily accessible, and, turthcrn'iore, the channel entrances are brought to an inverted upright position to cause any matrices that may have clogged therein to discharge by gravity therefrom. To facilitate swinging oi the channel entrances to and from operative position, a handle 82 is lined to the frame 27 of the channel entrance mounting this, handle serving as means "for manipnlating the channel entrances.

The structure thus l ar desii'rihed enables the channel entrances to be easily and quickly removed from operative relation with the distributing mechanism, disconnected from the magazines and swung into an inoperative position where they will be clear the niagazines when the latter are swung rearwardly for removal or changing of magazines, and the channel entrances may be easily and quickly restored to operative position. lVhen it is desired to swing the magazines rearwardly into magazine removing position, the handle 82 is first grapsed and pulled downwardly. This operation rocks the frame 27. together with the channel entrances thereon in a direction downwardly and rearwardly about the pivot 30 while the frame '28 still rests on the stops 68. The

llO

. until the abutment surface 43 thereon reaches channel entrances are thereby carried from the position shown in Figure 1 or by the dotted lines in Figure 2 into the full line position shown in Figure 2 through the are designated T, this relatively sharp downward movement of the channel entrances enabling their upper ends to clear the lower distributor screws and at the same time detaching the forward ends of the channel entrances from the upper ends of the respective magazines. This downward and rear ward movement of the frame 27 continues the abutment surface 42 on the frame 28, whereupon a continued downward pull on the handle 82 will cause the frames 27 and 28 to swing in unison in a rearward and downward direction about the pivots 29, through the are designated U in Figure 3, so that the channel entrances and their mounting move from the position shown by the full lines in Figure 2 to the full line position shown in Figure 3. lVhile the channel entrances and their mounting occupy this latter position, the magazines may be swung or rocked rearwardly into a position to permit the magazines thereon to be removed at the rear of the machine. After the magazines have been restored to their normal position, as shown in Figure 1, the magazine entrances and their mounting are returned to operative position by a reversal of the operations just described, the frames 27 and 28 first swinging in unison upwardly and forwardly about the pivots 29 and finally the frame 27 swinging forwardly and upwardly about the pivots 30, the upper ends of the channel entrances being thus restored to operative relationship with the distributing mechanism and the forward ends of the channel entrances re-establishing operative relationship with the upper ends of the respective mag azines. The springs 65 act to hold the channel entrances in their normally operative position and they also serve to counterbalance the channel entrances and their mounting, thus enabling the operator to swing the channel entrances to and from operative position with greater ease and facility. These springs also act to hold the abutment surfaces 42 and 43 of the frames 28 and 27 in engagement after-the pivots 30 connecting these frames have passed above the plane in which these springs act and, hence, during the return of the channel entrances to operative position, their upper ends will swing through the are U, thus insuring clearance between the channel e'ntrances and the lower rear distributor screw during the return of the channel entrances to operative position. Preferably, the weight of the channel entrances and their mounting is so distributed with respect to the strength and action of the springs 65 to cause the channel entrances and their mounting to rest by gravity in either of the two inoperative positions shown in Figures 3 and 4-.

The channel entrances and their mounting have been hereinbefore described as applied to the main magazines of the machines, but

when it is desired to apply such channel entrances to a machine which embodies a socalled side magazine unit containing auxiliary magazines 13 and 14', an extension frame member 27 is attached to the frame 27 as, for example. by screws 86 which secure lugs 87 on the extension frame member 27' to similar lugs 88 which may be formed on the frame 27 so that the extension frame member 27 for the side magazine unit becomes, in effect, a part of the frame 27. This construction enables a side magazine unitto be applied to the main unit of the machine equipped with channel entrances embodying the present invention and enables the improved channel entrances to be applied to the side magazine unit without altering the operation of the main unit of the machine. The extension frame member 27 may be provided with a leg 89 having a laterally projecting pivot pin 90 thereon, this pivot pin being arranged to enter a seat formed in a lug 91 carried by an arm 92 attached to a part of the stationary frame of the machine. lVith this arrangement, the pivot pin 90 will enter and rest in the seat in the lug 91 when the channel entrances are moved to their operative position, the arm 92 then assisting in sustaining the weight of the extension frame member 27 and thus insuring proper relationship between the channel entrances and the distributing mechanism and the magazines.

In machines of this general class, means is usually provided for automatically interrupting the operation of the distributing mechanism when the channel entrance is removed from its normal operative position or when a matrix becomes ammed between the distributor screws and a partition of the channel entrance. The present invention enables such automatic stopping means to be accommodated between the channel entrances. As shown, a space is provided between the adjacent upper edges of the channel entrances 24 and 25 in which is mounted longitudinally disposed automatic stop bars 93 and 94, the bar 93 being supported by the entrances for the main magazines and the bar 94- by the entrances for the side unit magazines. The adjacent or inner ends of these bars abut, and the bar 9 1 and by it the bar 93, are yieldingly held in the right-hand position by a tension spring 95 which is connected to the bar 94:. Each bar is provided with fingers 96 which are spaced to conform with the spacing of the flexible channel entrance partitions 23, the fingers projecting laterally from the upper edge of the bar and engaging ears 97 for'med on the upper proximate edges of the channel entrance partitions. lly this arrangement if one of the channel entrance par itions is moved toward the left in Fig. by a matrix becoming jammed between it and the distributor screws, the bars 93) and 94: will be correspondingly moved, and this movement of the bars will bring the slot 98 in the bar 94 into registration with the finger 95) carried by a rocla r 100. This rocker is a, part of the well-known automatic distriluitor clutch meclnmism and it functions in a manner well understood by those skilled in the art. When the linger 9E) registers with the slot 98 it enters said slot, thus permitting, the lug 101 on the rocker to move into the path of the cam 3 mounted on the constantly revolving shaft 10;) of the usual distributor clutch mechanism, this engagement of the lug 101 with the cam ltrii causing the clutch mechanism 10% to interrupt the drive of the distributor. li y mounting the automatic stop bars between the channel entrances, the fingers 96 on the upper edges of these bars may act in common for the partitions Lil of the front and rear channel entrances, thereby enabling one bar to serve for both entrances. It will be understood that when the channel entrances are removed from their operative position, the bar 94: will be removed from the lug; 99 and the distributor driving clutch will be automatically disengaged in a n'ianner which is well understood in this art.

lVhile the invention has been illustrated and described as applied to a machine of the so-called mixer type, containing two matrix magazines, it will be understood that it is also applicable to machines of the type containing either a single magazine and the usual single type of distributor or containing; more than two magazines.

By mounting the channel entrance or entrances on a pair of frames which are pivoted for movement relatively to one another and also in unison about the center as hereinbefore described, the operations of swinging the entrances to and from operative position are greatly facilitated, as the first movement of the entrances will be in a downward and rearward direction which will lower the entrances out of operative relation with the distributor and will withdraw the entrances from the upper ends of the magazines, and the subsequent rearward and downward movement of the entrances will carry them out of a position beneath the distributor to a position which renders the distributor and the entrances readily accessible and which enables the magazines to be rocked rearwardly into magazine removing position vithout interference from the entrances.
