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

The preferred embodiment of the invention is shown in the accompanying drawings and will be hereinafter described in detail, but it is to be understood that the invention is not restricted to the precise construction shown since equivalent constructions are contemplated and such will be included within the scope of the claims.

In the accompanying drawings, the mold disk l, as shown in Fig. 1, is of conventional construction, it being mounted for rotation on a shaft 2 carried on a reciprocable slide mounted in suitable guides in the machine and having a bearing arm 3 projecting from a side thereof, the construction and operation of the same as in commercially used machines of the class referred to and forming no direct part of the present invention so that further illustration and description thereof is deemed unnecessary. Machines of this class as commercially used also employ a so-called first elevator or line transporter, the lower portion of which is designated 4 in Fig. 1, this first elevator operating in the usual and well known manner to receive assembled lines of matrices, to then lower the matrix lines into casting position in front of the mold on the mold disk and to subsequently elevate'the matrix line by upward movement of this elevator or transporter to a level where the matrix line is removed therefrom for distribution of the matrices. Since the construction and operation of the first elevator or transporter 4 are the same as in machines of this class as commercially used and such elevator or transporter forms no direct part of the present invention other than that its usual upward and downward movements afford means for controlling or motive power for moving the banking members according to the present invention, as will be hereinafter described, further illustration and description of such elevator or transporter is deemed unnecessary.

Machines of this class also employ a so-called knife block for trimming the sides of the slugs as the latter are ejected from the mold, one form of such a knife block being designated 5, it carrying the usual right hand and left hand slug trimming knives 6 and 1 respectively, the block being mounted on the usual vise frame 8 in which the elevator 4 is guided to move vertically, and the knife 6 is adjustable toward and. from the knife 1 by means of an annular rim 9 which is connected to a screw H! which is threaded in the knife block 5, rotation of this screw by the rim 9 setting the knives at difierent distances apart according to the thickness of the slug to be trimmed when the latter is pushed edg'ewise bethis slide being tween the knives during its ejection from the mold. Detailed disclosure of the construction and mode of operation of the knife block shown is set forth in U. S. Letters Patent No. 1,202,720 granted October 24, 1916, but it is to be understood that knife blocks of other forms may be used in carrying out the present invention.

The right hand and left hand vise jaws II and I 2 are mounted to slide toward and from one another in the upper portion of the vise frame, as usual in machines of this class, but these vise jaws in the present instance are provided with ribs l3 which project from the rear faces thereof which normally stand opposite to the mold, these ribs extending throughout the lengths of the respective jaws, and. these ribs are intended to cooperate with the mold in use while it is in casting position by entering a recess I4 which extends across the front face thereof, when the mold disk makes its first advance toward the vise jaws and the matrix line which, it will be understood, is clamped endwise between the opposed faces l and I S of the respective jaws, such advance of the mold disk taking place preparatory to the slug casting operation. Several molds maybe mounted in annularly spaced relation on the face of the mold disk, it being usual in practice to employ molds having casting slots which vary in size so that the machine may be set to cast slugs of different point size or thickness merely by selecting one or another of the molds. For example, the mold disk according to Fig. 1 is provided with four molds one of which molds however, does not appear since such mold and the adjacent portion of the mold disk is broken away to more clearly show the knife block and the banking elements associated therewith. Since Fig. 1 shows the mold disk as viewed from the rear, only the rear faces of the molds and the outlines of the casting slots therein are visible. It will be seen from this figure however, that the mold designated generally by the numeral ll stands in a horizontal position at the top of the mold disk, which is its casting position, it being understood that this mold, after the casting operation has taken place, will be brought, by rotation of the mold disk in the direction of the arrow in Fig. 1 through 270 degrees, into a vertical position at the left hand side of this figure and between the ejecting device and the knife block. Usually, and as shown, the casting slot IS in the mold I! is appreciably wider or higher than the casting slot 26 in the mold I8, and the casting slot 22 in the mold 2| is wider or higher than the casting slot in either of the molds I8 and I9.

Assuming that the ribs l3 on the vise jaws are of such vetrical height as to enter or fit into the recess M in the front of the mold l1, it will be evident that the mold ll can advance in the usual manner tobring its front face against the opposed faces of the vise jaws so that these parts come together in metal-tight engagement, as shown in Fig. 6, this being the relation of the parts during the casting operation. However, the three-quarter revolution of the mold disk, subsequent to the casting of a slug in the mold I! carries this mold to a vertical position opposite to the trimming knives, and the mold l8 will then occupy the horizontal or casting position at the top of the mold disk, and upon the second advance of the mold disk to bring the mold I1 into close proximity to the trimming knives prior to the ejection of the slug, the relatively narrow recess M along the front of the casing slot 20 A lug 52 fixed on in the mold l8 will not be suitable for entrance therein of the rib l3 on the vise jaws. Consequently, the second advance of the mold disk for the ejection of the slug from the mold in use would ordinarily be obstructed by engagement of the ribs on the vise jaws against the front of the mold which is then in casting position.

In machines of this class, the mold disk under ordinary conditions is arranged to advance the mold in use the same distance while it is in casting position as it does when such mold is in the ejecting position, and a banking surface or surfaces are usually provided at suitable locations on the knife block to be engaged by one or another portion of the front of the mold to support the latter against the forward thrust of the ejecting device, the usual ejecting blade E50 engageabie with the rear edge of the slug S being shown in the present instance. According to the present invention, banking surfaces are provided to support the mold during the slug ejecting operation which surfaces shorten or limit the extent of the second advance of the mold disk in order to avoid the aforementioned faulty condition due to the ribs on the vise jaws fouling against the front face of a mold in casting posi tion which is not suited to accommodate such ribs when another mold which has been selected for use is standing in the ejecting position. However, to enable the mold disk to make its full advance against the mold in use and in casting position during the casting operation, the present invention provides means for moving these banking surfaces out of active or limiting position during the casting operation and for moving these banking surfaces into active position to limit the advance of the mold disk only during the ejecting operation.

The means provided by the present invention for accomplishing the hereinbefore stated objects, as shown in the present instance, comprises a rock shaft 23 which is rotatably mounted in a bore 24 forming a bearing in the vise frame, this shaft having an arm 25 fixed to one end thereof and an arm 25 fixed to its other end. A vertical rod 21 is loosely connected to the outer end of the arm 26, as by a pin 28, the rod 21 being slidable in a slot 29 in the forward side of a plate 39 secured by screws (H to the knife block. or forming a part of the rod laterally therefrom is engagein a banking block 3 3, the latter being slidably guided for vertical movement in a slot 35 in the plate 39 and bearing on its forward side against an upwardly and rearwardly inclined surface 35 on a portion of the right hand knife opposite to the slot 35.

The outer end of the arm 25 is loosely connected, as by a pin 3'1, to a vertically reciprocable bar 38, the upper end of which is connected to a vertically disposed rod 39 having upper and lower banking blocks 45 and M thereon. These banking blocks are mounted to slide vertically in grooves 42 in the knife '5, they being held in 2! and projecting able in a notch 33 these grooves by upper and lower retaining plates 63 and 44 respectively, the forward sides 65 of the blocks M! and 4! being sloped to conform with the upwardly and rearwardly inclined surfaces 45 on portions of the knife l at each side of the grooves 42. v

The banking blocks 34, so and M are controlled or set into active and inactive positions automatically and at the proper times during the operation of the machine. In the present instance, the usual first elevator or line transporter of the machine is utilized to effect such control or movements of these banking blocks, for which purpose the lower end of the bar 38 is provided with a vertically elongated slot M to accommodate a stud 48 carried by a vertically reciprocable rod 49 which constitutes the main operating rod for the well known knife wiper bar 58 and wiper blade 5i which are mounted on the vise frame and are employed on commercial machines of this class for scraping chips removed from the slugs from the cutting edges of the trimming knives. The knife wiper is usually arranged to slide vertically up and down over the cutting edges of the knives under the influence of the vertical movements of the usual first elevator or line transporter 4, the latter having an arm 52 fixed thereto at its lower end and provided with a bore 53 through which the rod 49 is slidable, a spring 54 bearing at its upper end on a fixed collar 55 on the rod 59 and at its lower end against the arm 52 serving to yieldingly force the wiper blade 5i upwardly when the line transporter makes its upward stroke to carry the matrix line from casting position to distributing position. When the line transporter returns from its upper or line distributing position to its normal line receiving position, the operating rod 49, together with the bar 55 and wiper blade 5|, descend by gravity to return the wiper to its normal position shown in Fig. l.

The operation of the mechanism hereinbefore described, is as follows:

Assuming that a slug has been cast in the mold H which occupies the usual horizontal casting position at the'top of the mold disk, as shown in Fig. 1, the line transporter l which, at this time stands in its lowermost position to present the matrix line therein in front of the mold, ascends, subsequent to the cast, to an upper level for removal of the matrix line therefrom and distribution of the matrices. Prior to such ascent of the transporter, the mold disk, as usual, retreats rearwardly from the matrix line, and during the ascent of the line transporter from casting position, the mold disk is rotated 270 degrees by the usual driving pinion (not shown) in the direction of the arrow, Fig. l, to bring the mold ll to a vertical position opposite to the knife block, such rotation of the mold disk being stopped when the casting slot H3 in this mold stands in alinement with the slug passage or opening between the trimming knives 5 and l. Rotation of the mold disk to bring the mold ill to such position for ejection therefrom of the slug cast therein and the pushing of such slug forwardly between the trimming knives, results in locating the mold ill in the horizontal casting position previously occupied by the mold H, but since the recess l i in the face of the mold is is too narrow to accommodate the relatively wide ribs 83 on the vise jaws, the usual second advance of the mold disk, immediately preceding the ejecting operation, must be limited to such an extent as will avoid obstruction to such advance of the mold disk by engagement of the face of the mold ill with the ribs l3. Means for limiting the advance of the mold disk while the mold in use is in ejecting position is set during the ascent of the elevator or transporter 3 and while the mold disk is turning the mold in use to the ejecting position, such ascent of the elevator or transporter moving the banking surfaces on the banking blocks 3 ii and M upwardly by engagement of the stud as against the upper end of the slot ll in the reciprocable bar 38, such engagement taking place toward the end of the ascending movement of the transporter and rocking the shaft 23 sufiiciently to lift the bars 2? and 39 and thereby slide the banking blocks 34, 4E! and All in their guides and along the upwardly and rearwardly inclined bearing surfaces against which they rest, with the result that the banking surfaces of these blocks move rearwardly and upwardly from their inactive positions shown in Fig. 1, and in a direction toward the front of the mold opposite thereto. Such movement of the banking blocks will be clear from Fig. 2 which shows the position of the block 34 prior to the ascent of the transporter, and Fig. 3 which shows the position of this block at the completion of the ascent of the transporter, and from Fig. 4 wherein all three of the banking blocks 34, 40 and 4! are shown in the rearward position which they occupy at the completion of the ascent of the transporter.

The second advance of the mold disk now takes place, with the banking blocks 3-6, A and 4! in their rearwardly extended active positions shown in Fig. 4, in which positions these blocks limit such advance of the mold disk by engagement of the mold I7 against the faces of these blocks before the mold it, then in the upper horizontal or casting position, can contact with the ribs !3 on the vise jaws, the relation of the mold 8 with the rib-s 53 on the vise jaws at this time being indicated in Fig. 7. The banking blocks thus serve to support the mold disk against the forward thrust of the slug ejecting device, and at the same time they prevent conflict between the vise jaws and a mold standing in the casting position. Subsequent to completion of the ejecting operation, the mold disk again retreats rearwardly, but meanwhile the transporter 4 has descended from its uppermost or line removal level to its normal position between the upper level and the casting level, so that the stud 48 is no longer in engagement with the upper end of the slot ll. Consequently, upon retreat rearwardly of the mold disk, the banking blocks 34, as and ii are free to slide downwardly by gravity their guides, by a descent of the bars 27 and 39 which may then take place and, due to the inclination of the surfaces on which these blocks slide, the blocks recede forwardly or in a direction away from the mold disk, so that when the latter advances for the next casting operation, its advancing stroke will not be limited by the banking blocks.

The usual knife wiper operating bar, together with the line transporter as commonly used on machines of this class, thus serves as motive power for moving the banking blocks into and out of active position to interrupt the advance of the mold disk. These parts of the machine however, have been chosen for this purpose primarily because their movement is appropriate to effect the movements of the banking blocks at the proper times in relation to the casting and ejecting operations, and it will be understood that while such means for moving the banking blocks is generally preferable, other suitable means may be employed to accomplish the objects of the present invention.

Although the invention has been shown and described in connection with certain parts embodied in the usual form of slug casting machine of the class referred to, it is to be understood that the invention is not restricted thereto nor is it limited to the overcoming of the fault arising from the particular conditions hereinbefore set forth, since the invention may be adapted to meet other conditions requiring correction to remove similar faults in respect to establishing a proper relation between the mold at casting and ejecting positions and cooperative parts of the machine, or to the maintenance of such proper relation when it would otherwise be disturbed during the advance and retraction of the mold or mold disk in difierent operating positions.
