claims. (ci. 19e-61) The present invention relates to an improved form of slug guide for slug-sawing apparatus, such as are used in connection with type casting machines, such slug-sawing apparatus serving to saw into different lengths the type slugs cast by those machines. One such slug-sawing apparatus or attachment widely known in the trade is the Mohr Lino-Saw, and my invention has particular application to that device. This Mohr Lino-Saw is widely sold as an attachment unit for mounting upon type casting machines typically represented by the well known Linotype or Intertype machines.

In many instances it is desirable to have the type slugs of different lengths so asy to enable thevtype to be assembled more readily around advertising cuts, illustrations, etc. As above stated, the type casting machine is frequently provided with a slug-sawing attachment, such as the aforementioned Mohr Lino-Saw, for this very purpose of cutting the slugs to diierent lengths, although the different lengths can also be obtained by making appropriate adjustments in the type casting machine. When the slugs are of different lengths a problemis introduced in guiding the slugs into proper position down upon the assembly platform. The improved slug guide of my invention has particular reference to the guiding of these varied length type slugs down to the assembly platform where they are assembled in galley form or upon a galley stick. As each slug slides down the delivery chute leading to this assembly platform it comes to rest on the platform alongside a pusher member or slug jogger. This jogger or 'pusher then operates automaticallyy in a lateral or horizontal direction to push the slug 4s'idewise into its assembled relation tothe preceding slugs of the galley. Each slug should be guided down to the bottom of the chute or tothe bottom edge of the platform, and the lateral support or guidance of the slug should be maintained until the slug jogger moves the slug laterally into its assembled position in the galley. When producing slugs of different lengths, the slug guide should guide the short slugs as well as the long slugs all of the way down to the terminal position at the bottom of the chute, or bottom edge of the assembly platform, but the guide should not interfere with the horlzontal movement of the jogger. l-Ieretofcre, this has entailed the use of a folding type of guide made up of folding pivoted sections, such as is disclosed in Patent No. 1,358,972 issued to Charles L. Mohr on November 16, 1920. The pivoted sections of thisfoldingguide are adapted to be folded downwardly or upwardly to increase or oecrease the effective length o f the guide so as to accommodate short or long slugs respectively. However, this folding of the guide sections downwardly or upwardly entails a manual operation `to be performed by the type casting operator each time that a change is made from a long slug to a short slug or vice versa. This places another duty upon the type casting operator, and if he forgets to perform the guide folding or unfolding operation there is the likelihood of jamming or improper assembly of the slugs upon the assembling platform.

The fundamental object of the present invention is to avoid these difliculties by providing an automatically operating guide which automatically moves into and out of guiding position in timed sequence with the operation of the slug jogger. This automatically operating guide is effective to guide short slugs, long slugs and slugs of any intermediate length down to the terminal position at the lower edge of the assembly platform. At the same time, this automatically operating guide cannot interfere with the function or motion of the slug jogger because the guide is automatically moved up out of guiding position when the jogger pushes the slug laterally over into assembled position on the platform or gal-Y ley. Thus, the type casting operator is relieved of the duty of making any changes or adjustments inthe guide mechanism when changing from long slugs to short slugs or vice versa.

Other objects, features and advantages of the invention will appear from the following detailed description of one preferred embodiment thereof. In the accompanying drawings illustrating such embodiment:

Figure 1 is'a front perspectiveview showing my improved guide mounted on a slug-sawing attachment for type Vcasting machines;

Figure 2 is a fragmentary plan view showing the relation of the automatically moving guide to the assembling platform and slug jogger; and

Figure 3 is a transverse sectional view taken approximately on the plane of the line 3-3 of Figure 2.

My invention has its principal utility when mounted on a slug-sawing attachment for type casting machines, and that is the relation in which I have illustrated it in Figure l. As well known to those' skilled inthe art, this ligure shows a Mohr Lino-Saw, such being a slug-sawing attachment for type casting machines. 'Slug-` sawing attachments of this general type are disclosed in prior Patent` No. `1,264,541 issued to 3 Charles L. Mohr on April 30, 1918, and in the aforementioned Patent No. 1,358,972 issued to Charles L. Mohr on November 16, 1920.

In Figure 1 the vertical saw shaft |0 is the shaft that carries the rotary disk type of saw that cuts the type slugs. The front and side portions of the circular saw are enclosed within a housing |2 which is capable of sliding up and down along guide rails carried by the main bracket of the slug-sawing attachment. This housing carries the shaft l and saw H'With it for cutting the slugs at different heights. Behind this assembly of slug-sawing parts is the conventional mold wheel of the type casting machine provided with mold slots in which type slugs are cast, usually about 5 in length. As is well known to those skilled in the art, associated with the mold wheel is a reciprocating slug ejector which is adapted to force the type slug out of the mold. As the slug isY pushed out of the mold by the ejector it passes through a conventional trimming mechanism by which it is sized as to thickness. In front of this trimming mechanism is disposed the'slug cut-V ting saw within its housing |2. The saw is operative to cut each slug into an upper and a lower part, the point of cutting and the length of each part being dependent upon the vertical adjustment of the saw blade. The upper part of the slug is waste and passesA out of the machine down a waste chute, not shown, while the lower part of the slug carries the printing characters and is the finished type slug which it is desired to produce from the type casting machine. This lower or printing portion of the slug is designated S in its entirety, this lower portion drop-Y ping vertically down a narrow vertical guide chute 20 as soon as it is severed from the upper part of the original slug. From the vertical chute 2U the slug is deflected by curved guide plate 2| in a diagonally downward and forward direction into a delivery chute 22 which extends across the top surface of a downwardly and forwardly sloping assembly platform 23. This assembly platform has a lower marginal flange 24 which constitutes an end stop defining the terminal or delivered position of the slug in its travel down the delivery chute 22 into the final position preparatory to being movedy laterally by the slug jogger. It will be observed from Figure 2 that the platform 23 is wide enough from' its lower marginal flange 24 to its upper edge 25 to receive the longest slugs, and all of the slugs. of whatever length, slide down said plat.- form to this terminal position in the delivery chute 22 withV their lower ends resting against the flange or rib 24 at the bottom edge Vofthe platform. At this terminal position the right hand side of the delivery chute 22 is defined by the. slug jogger 2.1 and the left hand side of the delivery chute is defined by the automatically operating guide arm 28 to which I have previously referred. At a predetermined time in the cycle, after a slug S has been delivered into the bottom of the delivery chute 22, the slug jogger 21 is automatically caused to move laterally toward the left for shifting this slug over into 4its proper assembled position in the galley on the assembling platform 23. concurrently, with this lateral shifting movement of the slug jogger, the guide arm 28 is automatically caused to swing upwardly to a position which will clear the slug so as to enable the slug to be shifted over into this position of assembly in the galley. Concurrently, with the return movement of the Y a laterally bent upward tip 21', whereby to gradually deiiect the descending slugs into the narrower delivery space at the bottom end of the delivery chute. This jogger plate is suitably secured to a right angle casting 3|, in the vertical flange of which are riveted two spaced guide pins 32. These guide pins have guided slidable support in guide bosses 33 formed integrally with a mounting casting 34 which is fixedly secured to the machine below the assembly platform 23. Coiled compression springs 3E are assembled over the guide pins 32 and extend into counterbores in the guide bosses 33, these springs normally tending to shift the jogger plate 21 toward the right into either one of two normal positions. 'Ihese two positions are. selectively predetermined by the rotation of a knurled stop head 38 (Figures l and 3). This stop head is mounted for a half rotation in any suitable manner, such as by a pin extending therefrom inwardly into a stationary mounting sleeve 33 and having a stud or pin projecting therefrom for rotative movement in an arcuate slot in the mounting sleeve. When the stop head is revolved to one position its inner end surface forms a stop for limiting the shifting movement of the jogger to the right; and when the stop head is rotated through a halfrevolution a notched recess 38h in the head is brought into position where it functions as the end stop for the movement of the jogger. In this latter situation, the jogger can move slightly further to the right for accommodating other widths or thicknesses of type slugs. This is conventional practice in the Mohr Lino-Saw.

Referring now to the actuating mechanism which automatically shifts the jogger towardl the left at a predetermined time after a type slug has been delivered down into the delivery chute 22, this actuating mechanism comprises an actuating lever 4| pivotally vmounted intermediate its ends on the downwardly extending pivot pin 42.`

The pivot pin 42 is carried by a mounting bracket 43 which is secured by'screws or bolts 44 to the main supporting *castingr 34.- When the lower' arm of the l1ever4| swings in-a clockwise directiontoward the; left, it transmits shifting movement'to the slug joggervthrough a compressionspring 46'. Thisuspring is vloosely confined between' the actuating lever andthe jogger by' a guide'pin 411which passesloosely 'through an aperture in the end Yof the lever and throughi The' purpose "of this spring is merely to permit the the springV and into the jogger casting 3|.

motion of thev `jogger to be interrupted without injury to the type slugs if there should be any jamming or interference ofthe slugs. As best shown in Figure 2, the. upper arm of the actuating'lever 4| extends into the bifurcated lower end Bla of a bell crank lever 5|. A pivotpin 52 extending vthrough this bifurcated end engages in an elongated opening 53 in the actuating lever 4|, for. transmitting motion fromthe bell crank lever to' the actuating lever. The bell crank lever is'pivotally mounted onapivotstud" 54' extending downwardly from "'the' mounting bracket 43. The other arm 5|b of the bell crank vlever extends into an actuating yoke or clevis 56, these two parts being pivotally connected `by a pivot screw 5l extending through the clevis and through a pivot opening in the lever arm. Extending rearwardly from the yoke or clevis 56 is a thrust pin 58 which has guided support in a guide boss 5S formed at the upper or inner end of the mounting bracket 43. The type casting machine comprises automatic actuating mechanism which is operative to impart outward thrusting movement to the thrust pin 58, such outward thrusting movementA operating through the bell crank lever 5l and actuating lever 4| to cause lateral shifting movement of the slug jogger 2lV to the left for shifting the previously delivered slug over into its proper assembled position in the galley. This automatic actuation of the slug jogger is a conventional practice well known to those skilled in theV art, and occurs when the ejecting plate is forced back against the vise frame of the type casting machine to receive the succeeding slug.

Referring now to the automatically operating slug guide 2-8, this is preferably in the form of a long narrow plate which may be punched from sheet metal or formed as a casting. The upper end of this guide plate has a pivot hole 28a for receiving a pivot screw El, and an inter.- mediate portion of the guide plate is formed with an arcuate slot 28h which has free swinging movement over a limiting screw 62. The pivot screw 6| and limiting screw 62 thread into tapped holes in a stationary upwardly extending guide plate 63. A mounting ange 64 projects laterally from the bottom edge of the guide plate 63, and is apertured or notched for receiving fastening screws 65 by which the plate 63 is iixedly attached to adjacent stationary parts of the slugsawing machine, although it could be attached to the assembly platform 23. The upper outer corner of the guide plate 63 is inclined outwardly to form a deflecting guide surface 61 for deiiecting any tipped slugs into proper position within the delivery chute. That portion of the plate 28 which projects beyond the lower end of the guide plate 63 has its lower edge notched out to form a long sloping bottom edge 280. It is this notched end portion that constitutes thel movable guide adapted to engage the adjacentV side surfaces of the type slugs, and the purpose of the sloping bottom edge 28o is to reduce the range of swinging movement that the guide plate is required to go through in order to clear the top edge of the type slug. rlhat is to say, by forming this bottom edge 28e along a slope, as indicated, this bottom edge is substantially parallel with the outer or top edge of the slug the instant that the slug is cleared, so that the entire length of the slug can be cleared by a smaller range of movement of the guide.

Auto-matic operating motion is transmitted to the movable guide arm 28 through the instrumentality of an operating arm 1I. 'Ihe upper end of this arm is formed with a longitudinal slot 72 through which pass two cap screws 13 which tap into holes 28d in the guide arm. This attachment of the operating arm to the guide arm 28 permits the operating arm to be adjusted upwardly or downwardly relatively to the guide arm. The operating arm H extends downwardly above the top edge of the platform, the arm preferably being curved substantially concentrically with respect to the pivotal motion around pivot screw 6|. The lower end of the operating arm is provided with a laterally bent extension 15` which4 lies substantially in the path of forward movementof'the front end of actuating yoke; 56; Theforwa'rd motion of this yoke when transmitting actuating-motion to the slug jogger 21 also transmits motion to the end 'I5 of the operatingarm 1| for swinging the movable guide 28 vupwardly to a raised position where it clears the top or forward edge of the type slug. If' desired, some lost motion space may be provided `and the vyoke 56,; so that the slug jogger will between the bent -end15 of the operating arm have actually started in its movement to the right for movingthe type slugV` laterally before the slug guide 28 is started inv its upward motion. These parts can beaccurately vtimed so that the guiding function of the slug guide 28 is maintained right up to theY point where the slug jogger is actually shifting the slug, and possiblypressing itli'gh'tly against the side of the guide 28. The provisionof the'compression spring 46 Vfor transmitting resilient pressureV to the slug jogger insures that the slug'guide 28 can be moved to its clearing position, even if the type slug should be pressed up against the side of this guide arm. With the guidearm raised to its slug clearing condition, the slug is-'moved over into its assembled position at the right hand end of the galley. Thereupon,'the slug jogger starts to move back through its return stroke toward the right,and substantially concurrently therewith the slug guidearvm'28 starts swinging down to its normal position. These two parts are auto-v matically returned to their normal positions in time phase with the automatic cycle of the type casting machine so that these parts havebeen restored to their normal positions before the next type slug is delivered down into the delivery chute. 22. It will thus be seen that the auto-- matically movable guide arm 28 is always effective to exert itsv guiding function on the type slug irrespective of whether the latter is a long slug, short slug or slug =of any intermediate length, and that this guide is automatically moved upwardly to a position where the slug is cleared when the slug jogger starts moving the slug laterally, all without'requiring any attention on the part of the type casting operator and without requiring any adjustment or change of parts when delivering long slugs, short slugs or slugs of any intermediate length.

While I have illustrated and described' what I regard to be the preferred embodimentof my invention, nevertheless it will be understood that such is merely exemplary and that numerous modifications and rearrangements may be made therein ywithout departing from the essence of the invention.
