Specification of Letters Patent.
Patented nec. 4, 1906.
Application filed February Z, 1906. Serial No. 302.338.
`Be it known that we, FREDERICK A. GOLES and FRANK SCHMITZ, citizens of the United States, residing at Depew, in the county of Erie `and State of New York, have invented certain new and useful. Im rovements in Machines for Making Cores, o which the 'following is a specification.
Our invention relates to .core-making rna` port and so attach our machine thereto that 1t may be quickly and conveniently swung into an inverted position for the removal oi the cores; to provide a core-receiving plate and means to retain the same against the upper end of the machine while the latter is being inverted; and to provide a frame and a core box vertically movable in said frame and' to equip the frame with core-ejectors, which serve also as the bottom oi the core-molding spaces.
With these and other objects in view our invention consists in utheconstruction, arrangement, end combination of parts to be hereinafter described, ai-idparticuiarly point ed out in the appended claims.
In the drawings, Figure l is a vertical transverse section of our improved core-making machine, showing the same hinged to a core makers bench, particularlyl designed for use in connection with this invention. Fig. 2 is aside elevation showing the inachine inverted and swung into lthe position shown in part in dotted lines in Fig. 1. Fig. 3 is a central longitudinal section of the' niachine inverted. Fig. 4 is a horizontal section Fig. 5 is a top plan view of' the machine. Fig. 6 is a side elevation of the machine inverted, showing the core-box elevated to eject the cores.
Referring now to the drawings in detail, like numerals of reference refer to like parts in the several'figures.
The numeral 1 designates a core-Inakers sand-table, on which a supply ot sand is kept to be used in forming cores.
2 designates 'a structure on which our improved core-malringmachine 3 is supported and which may'be considered part of the table, an extension thereof, or as an independent structure. ,'Said structure has two supports 4 and 5, arranged in different horizontal planes, whose difference in height is substantially equal to vthe height of the machine. As shown in Fig. 1, thernachine is normally a distance from the rontedge of the table for a purpose to appear hereinafter, and in order to conveniently convey the sand to vthe machine a lid or extension .6 is pivotally secured to the edge ot the table, which when in use is swung to the position shown in dotted lines, the free longitudinal edge thereof being in close proximity to or in contact with the machine; When not in use,
. the lid or extension may be swung onto the and supported on rods 11, passing through a' base-plate 12, nuts 13 being applied to the rods to lbea-r against' opposite sides of said plate. In this manner a rigid frame is provided capable of withstanding all strain to which it may be. subjected.
Within therectangular member, located at and forming the up er part of the frame, the core-box 8 is 'fitted to ireelj.7 slide therein, said core-box having' a number of core-forming spaces 14, into the lower ends of which )roject the core-ejectors 9, having their lower ends secured to the base-plate. Said core-ejectors are herein shown as having their lower ends reducedv and threaded, as at 16, to engage threaded apertures in the baseplate. By reason of theejectors entering the core-forming spaces they provide a bottom for said spaces. In order to hold'the core-box elevated, a spring-catch 17 or other locking device is provided. Guide-lugs 18 are provided at, the corners of the core-box and it the rods 11, which therefore serve as*A guide-rods for the core-box.
The upper irontedge of the machine, more core-box. When thoroughly tamped or pressed, a plate 19 is laid onto the top'of the machine and retained thereon .by levers 20, pivoted to the upper front edge of the ma* chine, the free ends of said levers extending beyond the upper rear edge ofthe machine to be grasped with extensions 21 formed on the rear face or' the rectangular member 10 ofthe frame. By grasping the Amachine in this manner it may be swung upward and forward onto the elevated support. When in this position, the machine 1s inverted. The space between the table and the machine is provided for clearance to permit the machine to be swung upward without striking the table.
When the mchine is elevated and inverted, the cores are ejected from the core-box by elevating the latter so as to slide on the guide-rods, preparatory to which action., however, the spring-catch 17 must be disengaged from the core-box. vFor convenience in elevating the corebox it is provided with handles 22. When the core-box is elevated to free the cores, the machine maybe swung down onto the lower support, leaving the plate 19 and the cores on the elevated support, also levers 20. The plate bearing the cores may now be removed and carried to an oven to bake the cores. When the machine is swung into normal position on the lower support, the core-box is to be' elevated into the rectangular member of the frame,`ater which the lid or extension on the table is swung into coperating position with the machine, thereby placing the latter in condition for forming another set of cores,
Changes in the form and construction of the several parts may be made without departing from the principles of our invention or sacrificing any of the advantages thereof, and therefore we do not wish to limit ourselves to the exact construction herein shown, but desire the claims to be given the broadest construction permissible by the prior art.
Having thus described our invention, what we claim is l. The combination with a structure having two supports on different planes and a table for the sand having a hinged extension, of a core-making machine having core-forming spaces in its upper side and being normally a distance from the'table to necessitate the use 'of said hinged extension for carrying the sand to the core-formin spaces, said core-making machine being hinged to the elevated support so as to be normally supported in upright position on the lower sup,-
port and be swung in inverted position onto.
the elevated support.
2. In a core-making machine, `the combination of a frame comprising a rectangular member open at the top and bottom, rods at the corners of said rectangularmember and a base-plate connecting said rods and having upstanding ejectors, and a core-box within said rectangular member and having coreforming spaces into which said ejectors extend to form the bottom of said spaces, said core-box being movable in said frame.
3. In a core-making machine, the combi-I members, a base-plate secured to the lower ends of said guide-rods, and npstanding ejectors threaded into the base-plate, a core-box having core-forming spaces into the lower ends of which the said ejectors fit and being normally held within the rectangular member of the frame, said core-box having guides vfitting said guide-rods, and means embodied in the construction of the machine to nornially retain the core-box in said rectangular member.
