APPARATUS FOR USE IN MAKING CORES OR THE LIKE.
Application filed September 2, 1919.
To all whom it may concern:
Be it known that I, Roscon C. PATTISON, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York,'have invented a new and useful Improvement in Apparatus for Use in Making Cores or the like, of which the following is a specification. 7
This invention relates to apparatus for use in forming molds and cores of the kind used in metal molding.
The objects of the invention are to provide an apparatus of this kind by means of which a core box or pattern can'be rapidly and accurately drawn from a core or mold without requiring the. accuracy and skill which is necessary in withdrawing the core boxes or patterns by-hand; also to provide an apparatus of this kind which rapidly alines the core box or pattern in such a manner that the withdrawing of the parts of-the box or of the pattern can be quickly effected; also to provide an apparatus of this kind which is simple in construction and inexpensive to manufacture; also to improve the construction of apparatus of this kind in other respects hereinafter specified.
In the accompanying drawings:
Figure 1 is a side elevation of an apparatus embodying the invention showing a core box in place thereon.
Fig. 2 is a similar View thereof showing the movable parts thereof in different positions.
Fig. 3 is a top plan view thereof.
Fig. 4 is a transverse sectional elevation thereof on line 4-4, Fig. 3.
Fig. 5 is a central sectional elevation of one of the magnets detached from the apparatus.
Briefly stated, the apparatus shown in the drawings and embodying the invention in cludes a base having a supporting part on which the work, such as a core box with a core, may be placed, and guide portions or tracks on which one or more core box'gripping devices or electromagnets are slidably arranged. These gripping devices or electromagnets are provided withfaces or parts adapted to grip or to be drawn by magnetism into engagement, with corresponding parts, plates ordisks on the core box in such a manner as to aline the core box on the apparatus. When the core box is properly alined; the parts thereof. may be WllillflllWH from the core by moving the grippingde- Specification of Letters Patent.
Serial No. 320,969.
vices or electromagnets lengthwise of the guide portions or tracks of the apparatus.
The apparatus is hereinafter described more particularly as used in connection with the forming of cores, but it will be un derstood that the apparatus is not limited to such use but may be used for making molds or for analogous purposes.
A represents the base or frame of the apparatus which may be of any desired shape or proportions, that shown having an enlarged intermediate portion preferably provided with raised ribs a on which a plate or board supporting an inverted core box and a core may rest. The base is also provided with longitudinal guide rails or tracks at, those shown forming the edges of a central slot extending lengthwise of the base, and being arranged parallel to the plane of the upper faces of the raised ribs 64. The base is preferably provided with a plurality of connecting members a which connect the two sides of the frame and with feet or legs a" by means of which the apparatus may be supported on a bench or table. A frame or base of any other suitable construction may be employed.
Gripping devices or magnets are slidably arranged on the guide tracks of the base in any suitable manner. In the construction shown these gripping devices have bory portions B provided with base portions 6 having slots or guide parts adapted to co operate with the guide rails or tracks a so that the gripping devices are movable lengthwise of the base. Any suitable means may be provided for causing the gripping devices to engage the core boxes relatively to the base of the apparatus. In the con struction shown for this purpose the gripping devices are in the form of electromagnets, each comprising a coil C which is inclosed in an annular slot or recess in the head 0 of the gripping device. The coil surrounds a central post or core 0 and is preferably held in the recess by means of a disk or plate 0 of non-magnetic material which may be held in place in any suitable manner, for exampleby means of a nut which engages the outer threaded end of the post or core 0. The open end or face 0* of the head 0 is preferably arranged in a plane perpendicular to the guide rail or track. The gripping device be provided with any desired means for facilitating the handling of the same, for example with a Patented Aug. 24 1920.
projection c on the top of the gripping device and with a handle or the like 0 ary trated, and means (not shown) are preter-v ably provided which are operable at will for connecting the conductors with a source of power to energize the magnets.
In order to enable the core boxes toJcooperate with the apparatus described, each of the two halves I) I) of a core box is provided with parts with which the ping devices can cooperate to alin'e the core box and to draw the two halves of the core box away from the core. I'Vhe'n the gripping devices are in the form of electromagnets as shown, the core boxes "must be either made of magnetic material or made of wood or other non-magnetic material, they must be provided with plates or parts (Zsecured to the core boxes'and provided with fiat facesjwhich are arranged in planes perpendicular to the direction in which the parts of the core boxes must be moved in order to clear the core. These faces are so arranged on'the core box as to cooperate with the :taces of the electromagnets. d d represent devices for locking'the two parts 0t thecore box'together when the sand is packed therein, (Z3 represents a plate or board which is adapted to be placed over the open end of the core box after the box is packed with sand, and which forms a base or support for the core alter the two halves of the inverted core box have been drawn from the core and E, Fig. 2, represents a core.
In the'operation of the'apparatus the core box, after the sand has been tl'ioroughly packed therein, is inverted and the plate d is placedupon the supporting ribs a or" the base. The gripping devices are then moved into operative rdation to the core box and the current is passed through the coils of the 'electromagnets to energize the same. hen the electromagnets are energized, the outer faces of the plates or parts (J will be drawn into contact with the faces 0 of the electromagnets, so that the core box will be properly alined on the base. The locking devices which hold'tl e two parts of the core box together are then releasedv and. the two halves of the core box can be drawn away from the core by moving the gripping devices lengthwise of the guide tracks. By
means of this apparatus the making of cores 1 greatly facilitated so that this work an be done by unskilled men. It is not necessary to use any precautions in drawing the parts of the corejbox away from the core since by means oftheelectromagnet's the proper aliningiof the core boxon the apparatus is insured and: the guide rails insure the proper drawing of the parts of the core box away from the core so as to prevent any damage to thecore.
