CASTING-ramienia.
-- Specification of LetterslPat en t.
Application filed August 3, 1908. Serial No. 446,741. i
the art of `making metal castings and espe-.
cially to the mann'er of making pat-terns from which the castings are molded.
The especial object of the invent-ion which forms the subject matter of this application is to provide a molding plate or composite pattern in which a plurality of individual patterns, either of like or different design maybe grouped -or joined to' facilitate the casting at ,a single operation of a number of small pieces.
' A further object is to dispense with the more or less expensive gates and produce castings with such accuracy as to save the waste from spoiled eastings incident to the-Operations as carried on under present methods and with the appliances in' general use.
A further object of my invention is to save the making' of theusual metal patterns where a number of small castings are to be made from a single pattern, and to eliminate to a considerable degree the hand-work required in the production of patterns under existing methods.
In the ac'companying drawings .I have illust-rated the manner of carrying out my' invention with devices which may be varied in form and arrangement without afliecting the essntial principles involved.
In the drawing:-Figure 1 is a plan view of a composite pattern produced according to my invent-ion and a suitable holder or frame therefor; Fig. 2 is a Vertical sectlon on the line 2--2 of Fig. 1; Fig. 3 is a crosssection on the line 3-3 of Fig. 1; Fig. -i is a cross-section on the line 4-4 ofFig. 1. Fig. 5 is a view partly in elevation and partly in section, of a flask and pattern used in carrying out my invention; Fig. 6 is a perspective view of a pattern section or unit according to my invention.
Referring to the details of the d1'awing 10,) represents a rectangular frame made preferably of met-al though any suitable wood may be used if desired. At each endof t-he frame is an ear 11 having a hole 11a to receive the flask pins 25 when the parts are assembled.
In the inner edge of the frame is a V-shapedgroove 12. One of the end bars of the frame is hinged as at 13, and det-achably secured at its other end by a pin 15 which engages a hole in the rabbeted end'll of the opposite side-bar. i
16 represents a partition strip or bar which extends transversely of the frame and is formed with enlarged ends 18 and with longitudinal V-shaped grooves 17 which ex'- tend along its opposite edges. This `bar is removably arranged in the frame and may be slid back and forth in the grooves 12, and several may be employed in a single frame if desired. M
` Patent-ea Feb. 28, 1911.
19 represents a pattern plate which is es- I pecially adapted to coperate with the improved frame or holder described. This plate is preferably produced from aluminumthough any suitable metal may be used. lIt
.is formed with beveled edges 21 .on three of its margins and with a plane edge on its other margin. This plate 19 forms a foundat-ion for the pattern 20 which is made in two c mplementary half Sections and the sect-ions rigidly seeured to opposite faces of:
thev plate so that they register perfectly, or the pattern and plate may be cast integral if desired.
.dinary molderls flask, 23 the bottom board,
24 the lugs or ears on the ends of the cope and drag, and 25 the pins which hold the cope and drag in their superimposed relation.
In 'the use of the parts described I first prepare a pattern of the part from which castings are to be made, such pattern to be made in two parts. The plate 19 is then formed and .the parts secured to its opposite sides so that they register perfectly. From this initial or primary pattern as many castings as may be needed may be made, each comprising a plate 19 with its beveled edges 21, and these duplicates are preferably made Stood that should it not be-convenient to use an even number of pattern plates, a blank plate may be inserted as a filler in order to'lock the plates securely in the frame. In utilizing the parts described, lthe .first the same manner as the first, and when in place, the gate'bar 21 i s closed` and fastened by the pin 15. The composite pattern member described, is now ready to be used in producing castings. It is placed between the cope and drag with the pins 25 passin through the openings 11a, and the san placed and tamped on the upper side in the usual manner. When the cope has been filled the board 23 is placed over the cope and the entire form reversed and the other or drag side isfilled and tamped. The form is then returned to its initial position4 and the cope removed, then the pattern is taken out and the cope returned to the drag-and the met-al poured into the mold thus formed.
It wil1 be noted that there is no possibility of non-registry of the complementary parts of a pattern when formed by my improved method, care having been taken that said parts are secured'to the plate 21 in perfect registry-I i It will be apparent that various constructions may be adopted for the'plate holding frame and that the plate itself may be modified in details without departing from the essential features described. I
What I claim is 1. In a molding appliance, a frame having groove's in its inner edges, one side of sai frame being pivoted at one end and detachably connected at its opposite end.
2. In a molding appliance, a pattern hold ing frame having a cross-bar removably arranged thereon, said bar and frame having grooves in their edges, and one side of said frame being detachabl'e from the adjacent members.
In testimony whereof I aflix my signature in the presence of two wtnesses.
