More particularly, it relates ,to machines of the lt le mese nerer ty; h rein he m sa: in emm a l n we d y a downwar ly in the machine frame to bring different selected magazines into operative relation to the assembling and distributing mechanisms, There are several different commercial models whichjmakeup this class of machines and the present invention has been developed particularly in connection with those modelswhich include asfeatures the r m ts, closed p ication or U. S. Letters Patent, ,Serial No., 171,584, of John H. p a fi J ly 1, 95 V. I h se ma n s the sh ft of the. magezines is efiected bya crank handle located at the front of the machine and connected to a magazine elevating mechanism which provides for a quick, easy and smooth shifting. of the magazines in changing from one to another. Preparatory to shifting magazines; however, the depression of a hand leveris requiredto; release the locking mechanism and to perform various safety functions prior to shifting magazines. Thus, for example, to avoid the dangers arising from a matrix lodged across the line of communication between a magazine entrance and a magazine at the time of shifting, the magazine entrance is adapted tobe swung bacl zwardly out of its operative position in response to the operation of the handlever. U Moreover in order to prevent the shifting of magazines, when the matrices are in the process of distribution, a matrix fee1er is adapted to move intq contact with anymatrices in the process of distribution and, consequently,

to prevent the releaseof thelocking mechanism upon contact Withanysuch rnatrices,

In accordance v vith the present invention, the above-mentioned and other safety features are efiectuated by improved electrical means. For xa e meet e...el ieg .mee n e i rendered inoperative, not only when matrices V 2 arein the process of distribution on the distribu: tor bar, and when a matrixbecomes lodged across the gap between the magazine entrance andthe magazine, but also, under certain conditions, when matrices in the course of distribution have notas yet reached the distributor bar but are still in the processvof being advanced through the upper distributor box. In other words, under any of the three stated conditions, the maga zine shifting mechanism is positively locked out of ra io ,7 ln addition, the present invention also pro.- vi e n impro e s stem f sa e na mps Other such signal .-,systems have heretofore been Pr d. i n ell the ha e ol the use of danger signals to indicate unsafe con;- ditions. a When trouble occurs in the safety sysem i pe f emnu ual ail v to n tion. wi h t e re u t that tbe-e e ermisled o believing that a safe condition exists.

. t embed ment lust ated, the present improvementshave been shownasapplied to. asocalled mining? machine, equipped'with four in: cline'd magazines A A A and A removably rices therefrom, one at a time.

mounted on separate base frames conjointly constituting a shift frame, which is arranged to be moved upwardly and downwardly by operation of a crank handle A at the front of the machine. The magazines are selectable in pairs, instead of singly, so that matrices may be withdrawn from either magazine of the selected pair and, after the casting operation, returned by the distributing mechanism to their respective magazine channels. However, it will be obvious from the description to follow that the improvements are applicable to any multiple magazine machine of the shiftable variety.

The actual mechanism for raising and lowering the magazines is well known in the art and forms no part of the instant invention. For present purposes, it suffices to say that the operation of the crank handle A through the long foreand-aft shaft A. and the short shaft G eifects' the upward and downward movement of an inclined magazine elevating slide F through counterbalanced gear mechanism denoted generally by the reference letter G.

Both operative magazines are served by a common distributing mechanism, denoted generally by the reference letter D. As well understood, the matrices, after the completion of the casting operation, are transferred onto a V-shaped second elevator bar C (Fig. 2), whereon they are lifted to the distributor box C and pushed, by means of a cam operated shifter bar C and pusher member C onto and across a stationary V-shaped bar C (Fig. 7) located in the box. Also located in the distributor box is a lifter C which rises at regular, evenly timed intervals, to feed the mat- Those matrices which are to be returned to the lower operative magazine pass onto the upper distributor bar D while those matrices which are to be returned to the upper operative magazine are permitted to fall into a chute C leading to a lower distributor box C from which they are individually fed, by means of another lifter C onto the lower distributor bar D (see Fig. 2). In either case, however, the matrices are advanced along the respective distributor bars D D by rotating screws D there being three of such screws associated with each distributor bar. After they are released from the distributor bar D or D the matrices pass through the appropriate magazine entrance D or D and thence into the corresponding operative magazine (A or A as in the case of Fig. 1 and A or A as in the case of Figs. 4 and 5), where they are stored until selectively released by the operation of the keyboard B.

As fully shown and described in the aforementioned Hilpman application, the inclined elevating slide F, which can be raised or lowered by the crank handle A to select the desired pair of magazines, is adapted to be locked in its different positions by means of a locating and locking pawl J 1 cooperating with notches F formed in the rear side of the slide. There is no need herein to fully describe the operation or functions of the looking pawl J except to point out that it is ordinarily maintained in its locking position by means of a spring J but is adapted to be withdrawn from the active notch by the depression of a hand lever J preparatory to shifting magazines. In addition, the hand lever J also effects the movement of matrix guards S across the discharge ends of the two operative magazines. If the matrix guards encounter any interference from a matrix protruding from the lower end of either magazine 4 in use, the hand lever J cannot be operated to release the locking pawl J As heretofore explained, one of the purposes of the present invention is to prevent the shifting of magazines when the matrices are still in the process of distribution, or when a matrix becomes lodged across the gap between the magazine entrance D or D and the corresponding magazine. Toward this end, therefore, a notched or toothed wheel G is secured to the shaft (it of the counterbalanced gear mechanism G. A pivotal pawl G under tension of a spring G (see Fig. 3) normally engages one of the notches of the wheel G thereby preventing the operation of the hand crank A to raise or lower the magazines. The pawl G however, is connected to a solenoid or equivalent electrical element E which, when energized, withdraws the pawl C from engagement with the wheel G to permit the shifting of the magazines. To briefly summarize the general scheme of operation, the solenoid E is generally deenergized but, when the pawl J is released by the depression of the hand lever J preparatory to shifting magazines, a switch E is thereby closed to energize the solenoid, provided the matrices have all been distributed, and provided further that the magazine entrances are clear.

The operation of the various safety features can be best understood by reference to Fig. 7, showing the electrical circuit and the various mechanical parts associated therewith. The elements of the control circuit are housed in a control box E (Fig. 1), wherein the usual source of A. C. voltage is fed into a step-up transformer and tapped oil in the various quantities needed. One of said tap-offs leads to the heater 3 of a thyratron control tube 2, said heater serving to bring the cathode 5 to the proper temperature to cause electron emission therefrom. When a safe condition prevails in the distributor, the thyratron conducts positive half waves of current to complete a holding circuit for a relay 3. As shown, the screen i and the grid 6 of the control tube are tied to the cathode, the latter being tied thereto through a time delay condenser 9 and resistor it. The holding circuit for the relay 4 may be traced from the cathode 5, tied to ground, to the plate 8 and back to a volt tap-01f through the relay A smoothing condenser [1 in paraliel with the relay 3 serves to even out the flow of current for the holding circuit. When energized, the relay 4 serves to hold contacts H and i2 closed to maintain the solenoid E in readiness for operation but, when the relay i is deenergized, the contacts are opened (as shown in Fig. 7) to prevent the energization of the solenoid Turning for a moment to the magazine entrances D and 13*, it should be evident that the magazines are adapted to be shifted with respect to the lower or discharge ends of the said entrances and, as explained above, occasionally a matrix becomes lodged in the small space between its magazine and the corresponding magazine entrance (see Fig. 6). To prevent any consequent damage when the magazines are attempted to be shifted under these conditions, the lower or discharge end of each of the magazine entrances D and D is provided with pivoted upper and lower extension members or flaps K and K respectively. The lower flaps K are held in position by means of spring urged arms K (see especially Fig. 6), there being preferably two of said arms, one at each end, serving to hold each of said flaps The present invention has been shown and (16-; scribed as especially applicable to a mixer machine, but it should be noted that it is applicable as well to non-mixing machines. Also, the various safety features have been shown and described as applied to machines having only a bank of main magazines, but, of course, they could be likewise applied to machines having a bank of auxiliary magazines.

Also, it is evident that the present invention is not to be limited in any way by the voltages specified, or the type of current employed. In deed, the invention has been shown and described merely in preferred form, and obviously many variations and modifications may be made therein and in its mode of application which will still be comprised within its spirit. It is to be understood, therefore, that the invention is not limited to any specific form or embodiment, except insofar as such limitations are specified in the appended claims.
