CLAMP FOR MOLDERS FLASKS.
SPECIFICATION forming part of Letters Patent No. 474,352, dated May 10, 1892.
Application filed November 14, 1891. Serial No. 411,920. (No model.)
To aZZ whom it may concern.-
Be it known that I, \VILLIAM \V. ARCHI- BALD, a citizen of the United States, residing at Newport News, in the county of Warwick and State of Virginia, have invented certain new and useful Improvements in Clamps for Molders Flasks; and I do hereby 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 appertains to make and use the same.
My invention relates to clamps for molders flasks; and it consists of the certain novel parts and arrangement thereof hereinafter de scribed and claimed.
Reference is had to the accompanying drawings, wherein the same parts are indicated by the same letters.
Figure 1 represents a perspective view of an ordinary form of molders flask, the parts being clamped together according to my invention. Fig. 2 represents a side View of two of the clamp-pieces and illustrates the method of interlocking the same, and Fig. 3 represents an end view of one of the two interlocking pieces which together constitute the clamp.
A and A represent the two sections of the flask, which may be of any desired shape.
B and B represent two clamp-pieces, which are usually cast in the same mold and are exactly similar in every respect. They are preterably made of cast-iron on account of its cheapness, although many other metals would do equally well. One edge of each clamppiece is divided by lugs 1) into a number of notches, whose sides I) Z) are slightly dovetailed, and at the same time the sides I) taper somewhat, so that the protruding arms B Whose sides also taper upward and outward, may readily he slipped into any of the said notches and be wedged therein snugly. The holding-arms B are adapted to go over and under the sides of the flask, and the wedges 0 press the two sections A and A of the flask firmly together. It will be obvious that the two clamp-pieces may be readily applied or removed, that they need no special clamping apparatus, such as clamp-screws, bands, 850., and that they constitute an exceedingly cheap, convenient, and simple means of securing the two sections of the flask together.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
1. A clamp for molders flasks, consisting of two symmetrical and reversible rectangular pieces having holding-arms at their outer ends, dovetailed grooves on the side opposite said holding-arms, and wedge-shaped lockingarms adapted to slide into said dovetailed grooves, substantially as described.
2. A clamp for molders flasks, consisting of two symmetrical and reversible rectangular pieces B, having holding-arms B adapted to engage the sides of the flask, lugs I), having inclined sides I) and 6 forming wedge-shaped dovetail grooves, and wedge-shaped arms B adapted to engage in any of said grooves, substantially as and for the purposes described.
In testimony whereof I at'fix my signature in presence of two witnesses.
VILLIAM W. AROHIBALD.
