HINGE.
' Application filed April 13, 1927. Serial No. 183,582.
This invention relates to new and useful improvements 1n h1nges, and, especially to hinges for utilization onfoundr snap flasks,
where rigid corners are essentia Obviousl however, its application is not limited to sue structures.
The cope and drag of a molders flask are usually of rectangular formation comprising a box-like structure adapted. to enclose the sand in which the impression is to be'cast. The sides of the cope and drag are hingedly connected at the corners and are constantly being opened and closed during operation, thereby subjecting the hinged joints to wear. It is essential that the'rigid corners of the cope and drag be preserved, but, during the molding operations, sand is often inadvertently dropped upon the hinges, and the subsequent pivotal movements grinds the sand at the pivot points of the hinge, causing a wear which ultimately destroys the rigidcorner of the flask.
It is the primary object of the presentinvention to provide a hinge structure so mounted as to permit easy adjustments to compensate for the wear to which the hinge is subjected, whereby the rigid corner may be substantially .maintained.
Other objects of the invention will be madeapparent in the following specifications, when read in connection with the accompanying drawings forming a part thereof. In said drawings:
Fig. 1 is a perspective view of one of the corner hinges embodying my invention.
Fig. 2 is a top plan view of said hinge, partly in section.
Fig. 3 is a fragmentary detail, looking downwardly'upon the hinge joint, and,
Fig. 4 is a plan view of the hinge pintle, and associated washer and nut.
Now referring specifically to the drawings, in which like referencenumerals indicate similar parts throughout the several views, 1 and 2 indicate adjoining walls of the cope or drag pivotal] connected by a hinge 3. It is of course unrerstood that one'of the corners of the cope and of the drag is provided with suitable detachable fastening means, whereby to permit the swinging movements of the walls 1 and 2 on the hinge 3.
The hinge 3 is formed of twoleaves 4 and 5, each provided withapertures for the reception of screws or bolts 6, whereby to attach the leaf to the cope or drag wall. As
here shown the leaf 4 isprovided with an apertured ear7, projecting from and flush w1th the lower surface of the leaf 4, and with a similar ear 8 having its upper surface bej low the plane. of the upper edge of said leaf. The leaf 5 is also provided with similarly formed ears 9 and 10, these structures being clearly illustrated in Figs. 1 and 2.
As shown most "clearly in, Fig. 2 the ears 7 and 9, and 8 and 10, are respectively con- 7 nected by pintles or pins'll and 12, terminating in a conically-formed screw head 13 and 14 respectively, seated in a properly shaped socket formed in theears 10 and 7 respectively. In order to provide for adjustments to compensate for wear caused naturally, and augmented by the sand being ground between the pintle heads 13 and 14 and the sockets in which they are seated, and between the contacting faces of the ears 7 and 9, and 8 and 10, respectively, the walls forming the apertures in the ears 8 and 9 are internally screwthreaded, and the pintlesl l and 12 are each provided with a few threads engaging the threads in the ears 8 and 9. The apertures in the ears 7 and 10 are-merely drilled, and the portions of the pintles 11 and 12 passing through such apertures, are free of screw threads. To look the pintles 11 and 12 in set position, I utilize a washer 15 and a nut '16, mounted on the ends thereof.
With the instrumentalities positioned as above explained, and as illustrated in Figs. 1 and 2, it is clearthat, when wear has taken place between the ears 7, 9'and 8 and 10 re spectively, and between the head of the pintles 13 and 14 and their sockets, the rigidity of the corner'of the cope or drag will'be disrupted on account of looseness of the hinge 3 at the points referredto. To adjust the pintles 11' and 12 to compensate for wear, the H nuts 16 and washers 15 are backed ofl the ends of the pintles, and the heads 13 and 14 are each turned with'a screw driver until the lower face of the head more or less lightly contacts the socket in which the head rests. I
It will be understood that, since each pintle is equipped with threads '17, which engages threads on the wall defining the apertures in' the ears 8 and 9, rotation of the heads 13 or 14 will draw together the ears 7 and 9, and
8- and 10 respectively. When the necessary adjustment is effected, the washer 15 and nut 16 are replaced.
In orderto insure that the walls 1 and 2,
carried by the leaves a; and 5, define an exact right angle, each of the leaves is provided with it flange 18 formed at an angle to t which is seated the edge of the all '1 or-2, The vertical edges of the flanges 18, 18 are beveledat 19, as shown in Fig. 3, in order to insure a close lit at the corners of the Walls 1 and 2.
In View of the foregoing it will be obvious that I have provided a structure Which greatly facilitates adjustments to compensate.
