IMPROVEMENT Ill MAKING SAND GORES FOR AXLE SKAINS AND HUB BOXES.
JAMES e. HoLT, or CHICAGO, ILLINOIS. Letters Patent No. 59,840., dated November 20, 1866.
. i SPECIFICATION. 'TO- ALL WHOM IT HAY OONGERN:
Be it known that I, JAMES G. HOLT, of Chicago, in the county of Cook, and State of Illinois, have invented a new and improved Inode of making Sand Cores for casting Axle Skains aud Hub Boxes; and I doihereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in whichi Figure 1 is a side view of a core-box frame, having the core boxes and coping applied to it ready to receiveA the sand.
' Figure 2 is a top view of fig. l.
Figure 3 is a section taken in awvertical plane through two hub-box cores, core boxes, and frame. i Figure 4 is a perspective view of' a core box formaking cores for hub boxes, shown' in section.
Figure 5 is a perspective view of four sand cores, for making hub boxes.
Figure 6 is a vertical sectional view of two skain core boxes, their flask and frame.
Figure 7 is a view of two sand cores for casting axle skains.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to a new and useful mode of making sand cores to be used in casting axle ska'ins and hub boxes, the moulds for said boxes and skains being made in any su'itable'manner. I
The nature of my invention consists in the employment of conical core boxes, which are open at both ends, in conjunctionwith a frame which is adapted for supporting said boxes at both extremities and holding them rmly in perpendicular positions to the upper support, which latter is designed to receive upon it a flask or coping, all as will be hereinafter described.A y l To enable others skilled in the art to understand my invention, I will describe its construction and operation.
In the accompanying drawings, A represents a framewhich consists of two parallel and vertical plates which are formed on or secured, in a `perpendicular plane, to a bottoni plate, as shown in figs. l, 3, and 6. I prefer to make this frame A, of metal, and to strengthen it by'a cross-bar a, so that it shall not warp. Four holes are made, at suitable distances apart, through the bottom plate of frame A, which holes are closed at bottom by a fixed plate, ZJ; the diameter of each one of these holes should be such that the lower end of the core box, which is inserted into it, should t snugly therein, without being allowed to move.` The top of the frame, r A, is a perforated movable plate, B, which is fitted to -said frame, and held thereon by'dow'el pins or clamps, in a plane parallel to the plane 4of the bottom plate. The centres of the holes which are made through the plate B, should coincide with the centres of the holes directly beneath them,and through the bottom plate of the frame A. The holes through plate B should also be made so as to receive the upper ends of the core boxes snugly within them. The core boxes C, C, for making cores for hub boxes, shown in figs. I, 2, 3, and 4, are tubular cores, and they should be of such length that their upper ends will be lush with the upper surface of the plate, B, when` all the parts are in their proper places ready to receive the sand, as shown in iig. 3. vA coping or shallow flask, D, is put upon the plate B, and suitably secured thereon by pins or clamps. When it is desired tu produce an annular space or depression upon the interior surface of a hub box, a corresponding interior depression is formed on the boxes C, C, as shown in igs.'3 and 4, for producing the elevation, e, on the core. The fiat rings, which I have shown in the core boxes, will readily slip out of them when they are drawn from the cores. vThese rings, e', being made in two parts or halves, may be removed from the cores Without breaking the core in so doing. f
The core boxesand iiask are filled with sand which is rammed in the usual manner of making cores, after which the whole should be carefully inverted and the core boxes, frame, and plate, B, removed, leaving the sand cores, as shown in iig. 5, ready for receiving over them suitable moulds. T/he sand which is in the flask, D, serves as a bed for the sand having the moulds in it. A I
The cores for axle skains are made substantially in the manner above described for making cores for boxes," the only difference being, that an axle skain which is made very perfect and smooth is used as the core box, as shown in lig. 6. That portion of the largest end of the axle-skeincore box, c', which extends above or beyond one half of the bead, g, projects above the surface of the plate B, and produces a mould in the iiask D, as shown in g. 7. i
`Itwill be seen, from the above description, that I am enabled to produce cores with great facility, the axe: 'of which will be exactly perpendicular to the face of the sand bed in the flask D; consequently, when the mouldf are adjusted over the lcores the. latter will be in a proper position for receiving the metal around lahem, and producing a good casting. Y p
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-4 1. A frame which is constructed substantially as described, and adapted for sustaining core boxes in a fixed position during the operation of making a sand core.
2. The mans, substantially as explained, for making one or many sand cores upon a sand bed, so that the axis of the core shall be perpendicular to said bed, thus ensuring the'proper centering of the core in the mould for which it is adapted, substantially as set forth.
