IIARRY O. COOPER, OF OIIIOAGO, ILLINOIS.
MOLDING-MACHINE CHAPLET-ADJUSTER.
SPECIFICATION forming part of Letters Patent No. 632,246, dated September 5, 1899.
Original application filed December 19, 1898, Serial No. 699,720. Divided and this application filed May 3l, 1899. Serial No.
` 718,866. (No model.)
To ,ZZ whom it may concern;
Be it known that I, HARRY C. COOPER, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Molding-Machine Ohaplet-Adjnsters; and I declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanyingdrawings, which form a part of this specification.
My invention has for its object the production of a chaplet protector and adjuster for use particularly in a molding-machine where the chaplets are inserted in the flask prior to the introduction of the sand into the flask.
It consists of a combination of devices and appliances hereinafter described and claimed.
In the drawings, Figure lis a side elevation ot' my chaplet protector and adjuster. Fig. 2 is a vertical section showing the arrangement of the parts before the mold is formed. Fig. 3 is a vertical section illustrating the position of the parts after the mold has been formed. Fig. 4. is a cross-section on the line 4 4 of Fig. 2.
In carrying out the invention A represents a section of the Iiask or any part thereof* such, for instance, as the runner-box. The particular point at which the chaplet is inserted in the flask depends entirely upon the style and shape of mold to be formed. I have therefore only illustrated a small portion of the flask. In the flask is an orifice A', adapted to receive the stem B of the chaplet.
O represents a section of the pattern. Inasmuch as this may be of any shape or size I have illustrated only a small part.
It is understood, of course, that ,the mechanism comprising my invention is applied to a machine wherein the pattern is carried into the flask to form the mold-such, for instance, as that shown in my concurrently-pending application tiled December 19, 1898, Serial No. 699,720, of which this application is a di- Vision.
D is a tube engaged to the pattern by the threads D, and moving vertically therein is a tube E, having its end enlarged` as at E', to form a suitable bearing. A ring E2 also serves as a bearing and guide for the tube E. Another ring Il]B also acts as a bearing and guide for the tube E and also forms a stop to limit the upward movement of the tube E.
A spring Fis located in the tube D, one end-bearing on the end of the tube E, while the other end bears on the end of the tube D. This spring tends to keep the tube E normally in its outer position.
G is another tube inserted in the tube D and extending up also into the tube E. It is provided with a flange G', interiorly threaded to engage the threads DiI on the end of the tube D, so that it can be adjusted vertically in the tube D. The upper end of the tube G is recessed, as at G2, to permit any sand to drop down through the tube G, and a removable cup or cap G3 is provided on the end to catch this sand.
The operation will now be understood. Before the sand is inserted in the flask the tube E is adjusted so that it covers the head B of the chaplet and bears against the iiask. Now as the mechanism moves the flask A and the pattern O toward eachother the tube E will be forced down into the tube D against the spring-pressure until the head of the chaplet B comes into contact with the end of the tube G, which has been properly regulated through the screw-threads G', and forces the chaplet into the flask, as shown in Fig. S, just the requisite distance.
In order that when the pattern drops from the mold the tube E may be disengaged from the flask, there is provided a beveled springcatch H to engage over the end E of the tube E. This catch is not essential, although in some cases it might be desirable, and for that reason I have shown it.
It will be seen from the above description that when the tube E engages the chaplet B the chaplet is eifectually protected from the sand during the formation of the mold and is adjusted in the flask at just the point desired, so that when the mold is taken from the machine the chaplets project out in just the proper position.
What I claim isl. In a molding-machine the combination with a flask and pattern mechanism and a chaplet carried by the flask of a shield to protect the chaplet from the sand, said shield carried by the pattern mechanism and adapted to engage over and protect the chaplet, substantially as described.
2. In a molding-machine the combination with the ask and pattern mechanism and a chapiet carried by the ask of a tube carried by the pattern mechanism extending to and engaging over the chaplet, said `tube having a yielding support to permit it to recede as the pattern and chaplet approach each other, substantially as described.
3. In a molding-machine the combination with the ask and pattern mechanism and a chaplet carried by the liask of a shield carried by the pattern mechanism and extending to and engaging the chaplet, said shield having a yielding support to permit it to recede as the pattern and chaplet approach each other and a spring for keeping said shield normally in its outer or extended position, substantially as described.
4. In a molding-machine the combination with the pattern mechanism of a chaplet protector and adjuster consisting of a tube extending to and over the chaplet, said tube carried by a casing on the pattern mechanism and adapted to telescope therein and a stop within the tube against which the chaplWith the pattern mechanism of a chaplet protector and adjuster consisting ot' a tube eX- tending from the pattern mechanism to and over the chaplet, said tube carried by a casing on the pattern mechanism and adapted to telescope therein, a stop Within the tube against Whichthe chaplet may bear and by which it is adjusted and a catch adapted to engage the tube when in its inner position, substantially as described.
In testimony whereof I sign this specification in the presence of two Witnesses.
HARRY C. COOPER.
