AUTOMA'IICALLY-ADJUSTABLE SLUG MOLD.
Application filed-March 1923, Serial No. 624,007. Renewed June 10, 1925.
To all whom it may concern:
Be it known that we, MICHAEL C. KELLY and James D. Foorn, citizens of the United States, residing at Selma, in the county of Dallas and State of Alabama, have invented certain new and useful Improven'ients in Automatically-Adjustable Slug Molds, of which the following is a specification.
This invention relates to line casting, and has special reference to a mold sizing device for slug casting machines.
In the operation of an ordinary slug casting machine there is provided a wheel, which is known as the mold wheel, and which supports the mold in which the line of type arecast. This mold wheel has a rotary movement, and also moves toward and from a front member or support on which is mounted the matrix vise, this being a mechanism to clamp a line of matrices firmly in position in front of the mold. One jaw of such vise usually is a fixed jaw, while the other is movable, the fixed jaw being positioned in alinement with oneend of the mold cavity. Also there is supported an ejector and trimming mechanism, thelatter being commonly called the knife, and being supported at a position where three-fourths ofa revolution of themold wheel will bring the mold opposite the ejector. The ordinary operation of casting a line of type may be briefly stated as'fol lows: I
The matrices having been assembled and in the vise, the mold is brought up against the matrices and molten type metal is injected into the back of the mold from the melting pot/ The mold is then moved back and the mold wheel'revolves through three fourths of a revolution. When it reaches the position oppositethe knife and ejector, the mold is again advanced and the ejector operates to push out the formed slug or line through the knives which trim the line to type high size. It is common to provide means for regulating the length of the mold cavity so that lines of difierent lengths may be obtained, but the operation of regulating these lengths has always been heretofore effected by some manual. means, and has never been so arranged that the length of the matrix line determines the length of the mold cavity.
The principal and most important object of the present invention 1s to provide a novel and improved means for regulating With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details otconstruction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In carrying out the invention and in the embodiment herein disclosed, the mold wheel is indicated in general at W, the matrix vise at B, and movable jaw thereof at J. Also the knife and ejector mechanism are shown at K.
Supported on the mold wheel is a mold having a body provided on its face with a pair of longitudinally extending slots 11, andhaving at one side thereof a mold cavity 12, the upper side of which is closed by side member 13 provided withv legs 14 which extend transversely in suitable grooves or passages 15 formed in the mold body, and are heldin position therein bymeans of a cover plate 16. Also the mold body is provided with a series of transversely extending slots 17 wherein are slidably mounted the shanks 18 o'f mold sizing members each provided with ahead 19. These heads are arranged side'by side and have bevelled or cutaway portions 20 adjacent the shanks. The heads are of such width that they may extend entirely'across the mold'cavity 12 when the mold is opened to its fullest extent, and. by an inspection of Fig. 1, it will be seen that upon movement of a certain of these. members transversely of the mold, they will lie side by side at one end of the mold cavity, thus shortening the space for the lead. At the extreme end of the mold, there is also provided an additional sliding member 21 which serves to close this end of the mold in accordance with the movement of the width gauging member 13.
Pivotled alongside of the respective shanks 1.8 is a series of tilting levers 22, which have their ends turned upward so-as'to project into the slots 11. These tilting levers are each provided with a slot 23 which engages a pin 24 projecting from the respective shank '18. Thus, upon depression of the lower end of one of the levers, as illustrated in Fig. 1, the mold sizing member is caused to move outward across the mold cavity. Corresponding depressions of the other end of .such lever will, in. like manner, cause the mold sizing member to move inward and open such cavity.
This method involving the use of moving members suchv as 20 in connection with the mold cavity has been heretofore used, but no means has been provided to automatically cause movement of these members in conformity with the length of line as given by the matrices held in the matrix vise. In
the present instance, there is' provided a.
blade is so positioned that, when the mold is opposite the line of matrices, the blade will enter the lower slot 11, and press upon certain of the levers 22. It will be obvious that under the conditions of the blade and mo-vable aw being so alined, the lateral position of this blade will be regulated by the position of the jaw, and consequently, dillereut numbers of levers, in accordance with the position of the jaw, will be pressed upon as the matrix line is lengthened or shortened in the operation of casting. In other words, the shorter the line to be cast, the nearer the movable jaw will be to the fixed jaw of the device, and consequently, the greater will be the number of levers 22 engaged and operatedv by the blade 25.
It quite frequently happens in the operation of line casting machines that a change from one length of line to the other is made necessary by different conditions of the type setting, and these changes may take place with such frequency that resetting of the mold length to its greatest dimensions by hand would act to delay the work and inconvenience the operator of the machine. To avoid this, there is provided a second blade, which is fixed to one of the knife jaws in such a. position and manner that upon the mold being rotated to ejecting and trimming position, this blade will extend along the whole length of the upper slot 11 so that when the mold is moved forward in the operation of ejection, the blade will contact with all of the upper ends of the levers which have previously been actuated, and thus will restore the mold sizing members 20 to their original position. Since the blade 25 operates automatically in accordance with the position of the movable vise jaw and the blade 25 restores all parts automatically to their original position, the length of the cast line may be varied as often and as much as the exigencies of the case require without in any way delaying or hindering the operation of type setting and casting. Thus, the mechanism for detern'iining the length of the line cast is wholely automatic in its character.
In order to provide for the varying widths of lines, the movable side '13 and its arms let carry certain mechanism which cooperates with certain other elements on the top or cover plate 10. It is well understood that the heights of type are given in a peculiar measure termed points. Each of these points is equal to one-seventy second of an inch. Now in a ratchet mechanism based on teeth, only oneseventy second of an inch apart would be too fine to stand the wear and strain of ordis nary uses. There is therefore provided on the body 10, at each end thereof, a ratchet member 27, the teeth oi: which are spaced tour-seventy seconds of an inch apart, That is to say, these teeth have a pitch of four points in type measure. The legs 14 are slotted as at 28 and pivoted in the slots are L-shaped levers 29, each of which carries a series of ratchet teeth corresponding to the ratchet teeth just described. It will be observed that there are, four of these levers 29, and that the ratchet teeth on each lever are positioned in staggered relation to'the ratchet teeth on the other levers, the extent of displacement being one-seventy second of an inch, or the equivalent of one point. The levers 29 are held in engagementwith the fixed ratchet teeth by means of springs 30, each having slots therein to provide four spring ends, or onevfor each lever. The ends of these levers project upward through the slots 28 into a groove 31, so that they can be reached and depressed by the mechanism described below. Under these circumstances, it will be'obvious that as the movable side is moved away from the fixed side of the mold, one of the levers will engage solidly with the fixed teeth at each movementof one-seventy seconds of an inch. Consequently, the members 20, which bear against the movable side of the mold, cannot force the mold open, but it can only be increased in width by depressing the leyer ends and moving the movable side member. It is obvious that it may be readily moved into itsnarrowest limits. I
In order to prevent accidental movement of the members 20, there is provided on the shank of each member a slot- 32, which is engaged by a depressed portion of the spring 33 fixed on the bodyof the mold. These springs are so arranged that they will yield to permit forcible movement of these members 20 by the action of the blade 25, but
will resist movement due to any jar, such as takes place in the operation of the machine. a
It is also to be noted that the arrange ment for preventing the mold opening too wide acts to maintainfcorrect height of line forming the type body againstthe pressure exerted by the molten metal being injected into the mold.
- In drder to automatically adjust the width of'the line, certain mechanism is used which willnow be described.
I nism is shown particularly in Figures 13 and 14, wherein 34 indicates the movable knife of the trimming mechanism,- and this knife is provided with a longitudinal slot opening extends a plunger 37 provided with ahead 38 held outwardly by a spring 39. This plunger carries a rod 40 located in the slide and provided with cam'projections 41 which slide beneath arms 42 secured to the This mecha- 41 against the arms 42 thereby tilting the f said arms on their pivots bringing into operationthe fingers 46. These fingers thus act to free the ratchet teeth from each other, and leave the mold side so that it can be moved. Now, the operator, in adjusting the distance between his knives automatically adjusts the width of the mold. is
There has thus been provided a simple and eflicient device of the kind described and for the purpose specified.
It is obvious that minor changesmay be made in the form and construction of the invention without departing from the inaterial spirit thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.
