T0 @ZZ whom it may concern:

Be it known that I, GUSTAF ALEXANDER JOHNSON, a citizen of the United States, residing at St. Charles, in the county of Kane and State of Illinois, have invented a certain new and useful Improvement in Core-Setters, of which the following is a'speciiication.

My invention relates to machines or devices for placing cores. It is illustrated in the accompanying drawings, wherein- Figure l is a plan view of my apparatus. Fig. 2 is a plan view of the drag with my apparatus removed. Fig. 3 is an end view. Fig. 4 is a cross-section on the line-.L 2l of Fig. 1. Fig. 5 is a detail of the movable shield.

Like parts are indicated by the same letter in all the gures.

A is the drag or lower portion of the iiask.

B is a frame having at each end a projecting alinement device B', which 'cooperates vice B2 on the drag. The case B is provided with two rollers B3 B3, although there 'may beany convenient number of rollers. They are journaled` at B4 B4, so as to rotate freely in either direction. Each roller is provided with a longitudinal slot'Band it lmay have more than one suchslot, if desired. On the'frame A rises the side bars C C, connected in front by the cross-piece C. Thus there is made a cross-pieces C O and C. The space between these bars is iioored by the part D, which is arranged, as indicated in Fig. 4,in long troughlike bodies. VIn the bottom of the trough lies one of the rollers. The slot in the bottom of the trough is just filled with the roller, so that it is free to rotate; `but the cores above cannot drop out between the trough or bottom portion and the roller. Upwardly projecting from each roller at one end is an arm E, pivoted at E" to the bail E2, which is pro vided with a handle E3. By moving this handle and bail it is evident the rollers may be rockedback and forth. j

F is a device in which a series of cores F may be arranged. Its bottom portion is shaped so as to conform to the cross-section configuration of the core case or holder.

such a holder as F, properly iilled with cores, is set in position, as indicated at the lower part of Fig. 1. It will be observed that the part F2 projects, and if now the bridge F3 be placed in position, its projecting ears F4 F4 taking into the slots F5 F5, the core-holder F may be withdrawn, as indicated in Fig. 1, and the cores will be prevented from coming out with it, and by continuing this process the result will be that the core-case will be completely charged with a series of sets of cores. Two of such sets are shown in Fig. l.

G indicates the sand in the drag, and on its surface are arranged a series of patternprints G'. The object of my invention is to lay a series of these small cores in proper relation in these pattern-prints. Having done this my device is removed, and the upper portion of the iiask is put into position, whereupon the metal can be run in. The object of the invention, therefore, is to obviate the delays, inaccuracies, expense, and hand-labor involved in setting in place a large number of relatively small cores. My invention is of curse applicable to other than cores exactly such as I have shown; but I am showing it in connection with the cores used in the manufacture of links for link belting as presenting an excellent illust-ration of the use of my invention.

The separate cores J J are received into the slots B5 when the rollers are turned so as to bring that slot up into the core-chamber. 1f then the motion of the roller be reversed or continued, so as to bring this slot beyond .or outside of the bottom or floor of the corecase, the parts are so arranged that the little core will drop into the groove made in the pattern-print to receive. it,.as indicated in Fig. 4. By having two rows of such patternprints on each side it is possible to lay an entire set of these cores in eachof four rows of such pattern-prints by a single to-andfro movement of the handle connected with the two rollers. When the little cores are thus placed in position, the apparatus is re.- moved and the upper portion of the flask can be "put in place. By having the core-box substantially the same in form as the npper portion of the flask and using the same alinement devices the parts will always come into proper position. A suitable core-case and. core-setting apparatus will have to be adapted foreach particular form or size of flask.

I have shown two of the slots 135135 on each roller, the idea being that one slot discharges on one side and the other on the other by partly rotating the roller. Of course it is evident that one slot may be made to serve the purpose of both; but in that event the roller would have to rotate through a large arc.

The use and operation of my invention have been sufficiently shown in the preceding description. Itwill be understood, however, thatI do not Wish to be limited to the precise form and arrangement of parts shown, and some of the parts of my device are to be taken, in a sense, as diagrammatic, simply to illustrate its use, operation, and construction without confining myself to the particular form, size, and shape of the parts shown.

The method of arranging the cores in rows and packing them in a core-box, as Well as the device used for that purpose, can of course be greatly varied without departingr from the spirit of my invention.

The device F is intended to be used in transporting a group or roll of the cores to the machine or device for placing the cores, and after the cross or movable bridge piece F3 has been placed in position the part F can be pulled out, whereupon the row or group of cores will be properly arranged in position for use. I have referred lto this group or series of cores as F', meaning to indicate thereby the entire group. The separate cores in the group I have indicated by the letters J J. The two slots in the roller will obviously discharge one on one side when the roller is slightly rocked in that direction and the other on the opposite side when the roller is slightly rocked in that direction. The roller is a rocking and not a rotating roller, and when one slot is exposed to the cores to'be filled thereby the other is below the bottom and is discharging its cores.

I claiml. In a core-setter the combination of a core-case adapted to hold a series of loose cores with a movable core-delivering device mounted therein, and means for operating such core-delivering device to cause it to select, carry and deliver individual cores from the case to the pattern-print.

2. In a core-setter the combination of a core-case, having a trough-like bottom, with a movable core-discharging device mounted in such trough-like bottom, and means for moving it so that it will first take a core from the case and then deliver it to the patternprint.

3. In a core-setter the combination of a core-case with a trough-like bottom and a slotted roller mounted in such trough-like bottom, and means for rotating said roller so as To bring the slot iirst above and then below the bottom.

4. In a core-setter the combination of a core-case with a trough-like bottom and aslotted roller mounted in such trough-like bottom therein, and means for rotating said roller so as to bring the slot iirst above and then below the bottom, and an alinement device to bring the core-case in proper relation to the pattern-print.

5. In a core-setter the combination ot' a core-case with means for arranging the cores therein in a series of groups, a series of coredischarging devices mounted beneath such groups of cores, and means for rotating them so that they take cores from within the case and deliver them outside the case to the pattern-print.

6. In a core-setter the combination of a core-case with means for arranging the cores therein in a series of groups, a series of coredischarging devices mounted beneath such groups of cores, and means for rotating them so that they take cores from Within the case and deliver them outside the case to the pattern-print, said means consisting of slotted rollers in the bottom of the core-case.

7. In a core-setter the combination of a core-case with a movable bridge and a series of devices for holding said bridge Wherebythe cores may be arranged in groups in the case.

8. In a core-setter the combination of a core-case with a movable bridge and a series of devices for holding said bridge whereby the cores may be arranged in groups in the case, and a core-holder adapted to be moved underneath said bridge to discharge the cores in groups back of the bridge.

9. In a core-setter the combination of a drag with alinement devices, and a core-case with corresponding alinement devices, a core- 'discharging device mounted in the bottom of such core-case and adapted to receive the cores from the case and discharge them into the pattern-prints in the drag.

l0. In a core-setter the combination of a drag with alinement devices, and a core-case with corresponding alinement devices, a coredischarging device mounted in the bottom of such core-case and adapted to receive the cores from the case and discharge them into the pattern-prints in the drag, said discharging device consisting of slotted rollers with means for rocking them.

ll. In a core-setter the combination of a drag with alinement devices, and a core-case with corresponding alinement devices, a coredischarging device in the bottom of such corecase and adapted to receive the cores from the case and discharge them into the pat-ternprints in the drag, said discharging device consisting of slotted rollers With means for rocking them, and the bottom of said case provided With a series of troughs each of which terminates in a roller.
