JAMES MAGPHAIL, or MOLINE, ILLINOIS, ASSIGNOR, BY MEsNE ASSIGN- MENTS, TO KILLING MOLDING MAOIIINE COMPANY, OF DAVENPORT,
IOWA, A CORPORATION.
MOLD-FORMING MACHINE.
Specification of Letters Patent.
Ildatented April 16, 1907.
To all whom it nasty concern.-
Be it known that I, JAMEs MAGPI-IAIL, a 01 tizen of the United States of America, re-
siding at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Machines for Forming Molds for Metal Castings, of which the following is a specification.
My invention relates to improvements in machines for forming sand molds for metal castings, and has for its object the quickening of the operation of forming such molds by machines and the construction of a simple practical machine for that purpose.
I illustrate my invention by the accompanying drawings, in which similar letters refer to similar parts in all the figures.
Figure 1 is a side view showing the flask, and in dotted lines the flask drawn from the pattern. Fig. 2 is a top view. Fig. 3 is a vertical longitudinal section on the line X X of Fig. 2. Fig. 4 is a detail view of the stepped braces on a. Fig. 5 is a detail view of the forked end of the clamp.
The pattern-plate G, fitted with a pattern g, is mounted upon the base-frame A, either rigidly or eccentrically pivoted by a pivotpin 1', as shown, depending upon the form of casting to be made. I are slotted adjustable supports for the pattern-plate G, secured to the base-frame. Shallow castings can be made from a rigidly-secured pattern-plate, but deeper castings require a pivoted pattern-plate to give the pattern sufficient play to allow the mold to be drawn without breaking.
A swinging frame B is pivoted in uprights upon the base-frame A by pivot b.
A stripping-plate K is adapted to receive the flask H and is secured to the swinging frame B by pins J entering holes A removable clamp O is provided to secure the flask H and bottom board h in position upon the stripping-plate while the swinging frame is in motion. This clamp C has its inner end D forked and recurved to engage the swinging frame and its outer end (if formed into a handle adapted to be grasped by the hand of the operator, together with the handle E of the swinging frame A segmental rack F, having a series of pinholes F, is secured to the pattern-plate pivotally by apivot-pin F and extends through a slot in the swinging frame, and in. this rack works the spring stop or catch f, hinged to the handle E of the swinging frame and which holds the swinging frame raised from the pattern-plate when it reaches a certain height until released by the lever e. The spring 6 throws the stop or catch f against the rack F when not held compressed by the lever 0.
Many classes of castings can be removed with the swinging frame raised only sufficiently to allow the flask to clear the pattern; but when desired the swinging frame can be given a half-revolution around its, pivot, and when this is done the clamp O falls into the depressions of the stepped braces a a and is released by pushing it in the direction of the pivot of the swinging frame, thus throwing the forked end free from the swinging frame and allowing the swinging frame to be returned to its first position, leaving the bottom board and flask with the mold resting upon the braces a a.
In making molds the rapid duplication of the mold is an essential object. Heretofore in machines of this class afull half-revolution of the swinging frame has been required. In this machine only such a partial revolution of the swinging frame is necessary as will allow the stripping-plate to clear the pattern. The mold canthen be removed and the process repeated.
In operation the pattern is mounted upon the pattern-plate. The swinging frame carrying the stripper-plate is swung down to rest the stripping-plate upon the pattern-plate. The flask is placed upon the strippingplate, filled and rammed, the bottom board placed upon the flask, and the clamp placed in position to hold the flask and bottom board in position. The swinging frame is then raised until it will clear the pattern and is supported temporarily upon the segment-rack or through a half-revolution, as desired. The flask can be removed as soon as the swinging frame is sufliciently raised or swung through a half-revolution and released by pushing the clamp toward the middle of the base-frame or pivot of the swinging frame. The flask having been removed, the swinging frame is then ready to be swung to its first position and the process repeated with another flask.
