CORE-ARBOR FOR HOLLOW CASTlNGS.
SPECIFICATION forming part of Letters Patent No. 383,603,1ated rMay 29. 1888- Applieation filed Xovcmhcr 3, 1887.
To @ZZ whom, it may concern,.-
Be it known that we, W'ARREN E. WARNER and FRANK A. AUSTIN, respectively of Syraeuse, county of Onondaga, in the State of New York, and citizens of the United States, have invented certain new and useful Improvements.
in Oore-Arbors for Hollow Castings, of which the followingisa specification, reference being had totheaccompanyiugdrawiugs, in which-- Figure l is a transverse section of our corearbor; Fig. 2, a front elevation thereof; Fig. 3, a longitudinal section; Fig. 4, a top plan View; Fig. 5, a bottom plan View of a detached section; Fig. 6, a top plan view of standard detached; Fig. 7,' top and bottom detail views of the rounded or ball projection; Fig. 8, an enlarged detailofthe cam or screw fastener; and Fig. 9, a detail, enlarged, of the bolt that operates therein. Y Siniilarletters and figures of reference indicate corresponding parts throughout the sev eral views. r
Our invention relates, generally, to cores for making hollow castings; and our object is to produce a core ready for use without previous baking, using only wet sand and a sectional core-arbor within the sand.
Our invention consists in the several novel features of construction hereinafter described, 3o and which are specifically enumerated in the several claims hereunto annexed.
lt is constructed as follows: A is the core-arbor, madein hollow sections l2 3 4,&c.,preferably of rectangular forni in crosssection, the meeting ends of which are adapted to fit together, as shown-'i. e., the central horizontal faces of the meeting ends of the adjacent sections being in close contact and unyielding vertically andasuitable space or open- 4o ing formed between the vertical faces of said meet-ing ends, whereby the expansion of the parts under heat is arnplyprovided for. These sections are secured together at said meeting ends, preferably by a key-bolt, 5, inserted through an oblong hole at the top of and a circular hole at the bottom of the arbor, and a locking-wedge, 6, passing through the eye of the protruding head of the keybolt, about as shown; or we can secure the sections by a bolt,
Serial No. 254,155. (No model.)
7, the head of whichengages with au inclined or cani surface, 8, on top of the sections, as is clearly illustrated in the drawings. We form these sections hollow, both for lightness and also for ventilation of the casting, and 9 9 are perforations through the shell of the sections. We also provide the sections with longitudinal and transverse or circumferential ribs or flanges 10, which support the sand when packed between and over them.
B is a bearing to be used to adj ust thelevel of the core (or core-arbor) in the core-box and support it, said bearing consisting of a hollow standard, 11, provided with a socket-top fitting` the fixed or loose rounded or ball projection 12, beneath the core-arbor section, (thus constituting a. ball-joint,) and an adjustable bolt, 13, passing up through the standard, the ball, andthe section, asillustrated in the drawings.
O is a casting, with the core-arbor and core within it; and D represents the formed sand, said parts being shown in the drawings by dotted lines and dotted work.
In our employment of the key-'bolt 5 for securing the sections together we insert it from the top into and through the apertures or holes, then screw the nut up against the arbor-section, (the wedge alreadybeinglooselyinserted through the eye of the bolt-head,l and with any proper tool drive the wedge forward in the eye of the bolt until the respective sections are made or held perfectly rigid. or immovable vertically, yet at the same time allowing for the longitudinal or circumferential eXpansion of the sections under heat by reason of the vertical openings left between the vertical faces of the meeting ends. The aforesaid features of construction adapted to properly eon cooled, it is taken from the mold and suitably suspended, when a little rapping thereon will loosen the sand, which will come out of the opening or openings in the casting left for that purpose, and then through said opening or openings we uncouple and remove the corearbor sections, shifting the arbor along in the casting until thc bolts are reached.
In uncoupling the sections the fastening device 6 can be manipulated from either top or side, and that marked 7 8 from either the side, top, or bottom.
Such a green-sand core will retain its exact shape and not warp, no core-oven is necessary, and no sand is wasted, as it can be used over and over again by wetting it. Neither do we need or use any iour or other ingredients used in the making ot baked cores; also, the perforations in the sections permit the gas and steam to pass into the central chamber, 14, wherein it will pass around to and through an outlet from the mold. By the employment of our core-arbor (or core) hollow castings of any claim as new, and desire to secure by Letters Patent, is- A 1. A core-arbor consisting of removablyconnected hollow sections provided at their meeting ends with an overlapping part adapted to come in horizontal meeting contact with an adjacent overlapping part, and with a suitable space left between the adjacent upper and lower vertical faces of the meeting sections to permit of longitudinalexpansion under heat, substantially as described.
2. In a core arbor, in combination, two or more rectangular hollow sections provided at their meeting ends with an overlapping part that comes in horizontal meeting cont-act with an adjacent overlapping part, and provided l adapted to secure the sections together unyieldingly vertically, and yet allow for their longitudinal expansion under heat, substantially as described. j
3. A hollow corearbor section ot rectangular form in cross-section, with perforations in' its shell, and constructed with an upper horizontally-projecting portion provided with an oblong aperture at one end and a lower horizontally-projecting portion provided with'a circular aperture atits opposite end, and provided with a central longitudinal rib and transverse intercepting ribs upon its lower exterior surface, in combination, substantially as described.
4. A corearbor consisting of sections bolted togetherand mounted uponand connected to a supporting-standard by a ball-joint, substantially as described.
5. Acore-arbor mounted upon and con nccted to a supporting-standard by a ball-j oint, substantially as described.
In witness whereof we have hereunto set our hands this 14th day of October, 1887.
