JOHN TUOI-IY, OF BLACK DIAMOND, CALIFORNIA.

MOLDING-FLASK.

Specification of Letters Patent.

Patented Oct. 10, 1911.

Application filed June 7, 1911. Serial No. 631,784.

To all whom it may concern:

Be it known that 1, JOHN TUoHY, a citizen of the United States, residing at Black Diamond, in the county of Contra Costa, State of California, have invented certain new and useful Improvements in Molding- Flasks; and I do declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in metal molding paraphernalia, and particu larly to the molding flasks used for molding metal of all kinds, the object of the invention being to produce a molding flask which will have adjustable and interchangeable side members whereby the mold can be readily changed to any size or shape desired by the insertion of extra pieces or additions, as will appear.

A further object of the invention is to produce a simple and inexpensive device, and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in. the several views.

Figure 1 is a perspective view of my improved molding flask. Fig. 2 is a perspective view of an extra or additional side member. Fig. 3 is a sectional view taken on a line XX of Fig. 1. Fig. 4 is a fragmentary end view of a flask bar. Fig. 5 is a side view of a fragmentary end of one of the sides of the flask partly in section as on a line YY of Fig. 1. Fig. 6 is a perspective view of a wedge shaped key.

Referring now more particularly to the characters of reference on the drawings, I first provide side members of the molding flask as at 1, which side members have projecting tongues 2 on each end, such tongues having cross heads 3, and I then provide adjacent side members for said side members 1, which adjacent side members are provided with side grooves 5 at each end, which grooves 5 are of a shape to receive the tongues 2 and cross heads 3, whereby said members 4 may be locked to their adjacent members 1, as shown in Fig. 1. The said grooves 5 are provided with bottoms 6 to prevent the members 1 from passing all the way through the members 4 when the flask is in use.

When the members 1 are fitted in the members 4 by the structure described, a wedge shaped key 7 may be projected through members 9 hereinafter described and the members 2-3 or just round pins 8 may be used, whereby they may be held together for use.

In constructing my improved side members 4, they are cast of solid material sul stantially channel shaped with solid end members 9 in which are cast the slots 5. Similarly the side members 1 are cast in one solid member substantially channel shaped with end members-10, and with the tongues 2 and cross heads 3 cast solid on their ends.

The structure above shown of the tongue and groove mechanism is extremely adaptable for changing the size of the molding flask desired by addition of auxiliary or extra pieces 11 of different and varying lengths with the tongue and cross head structure on one end and the groove structure on the other end, whereby they may be inserted to change the size or shape of the flas In connection with my improved molding flask, the structure of which is above described, I have shown in Fig. 1 three different kinds of flask. bars which I will describe in order, namely: 1st: I can cast on the inner sides of the members 1 two spaced flanges 12, between which may flt a flat flask bar 13 held in position by either wedges or pins similar to the wedges 7 or pins 8. 2nd: A slotted guide 14 may be cast on the inner edge of the members 1 and a bar 15 having a projecting flange 16 fitted into said grooved guide 14 and held therein by wedges or pins, as above. 3rd: A flask bar 17 having cross heads 18 adapted to fit in grooves 19 formed by projecting flanges 20 cast on the member 1, the flask bar to be held in position by wedges or pins as shown. Any of these various forms of flask bars shown would 'be very adaptable and especially eflicient for circular molding flasks.

From the foregoing description it will readily appear that I have produced such a device as substantially fulfils the objects of the invention as set forth herein.

lVhile this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention.

Having thus described my invention What.

I claim as new and useful and desire to secure by Letters Patent is 1. A molding flask comprising side members, one of said side members being formed at each end with projecting tongues, cross heads on said tongues, the adjacent side members having corresponding grooves to receive said tongues and cross heads, said grooves having bottom members, as described.

2. A molding flask comprising side members, said side members being substantially channel shaped, solid members at each end of each channel, one of said side members being formed at each end With projecting tongues provided With slots, cross-heads on said tongues, the adjacent side members having corresponding grooves to receive said tongues and cross-heads, the solid members on said adjacent side members also being provided with slots adapted to register With the slots in said projecting tongues, as described.

In testimony whereof I aflix my signa- 30 ture in presence of two Witnesses.

JOHN TUOHY.
