HINGE FOR PlPE-FLASKS- SPECIFICATION forming part of Letters Patent N0. 773,224, dated October 25, 1904.
Application filed February 24,1904. Serial No. 195,035- (No model.)
To all whom it may concern:
Be it known that 1, SAMUEL RnIcHwEIN, a citizen of the United States, residing in the city of Reading, county of Berks, State of Pennsylvania, have invented certain new and useful Improvements in Hinges for Pipe- Flasks, of which the following is a specification.
My invention relates particularly to means for hinging together the sections of flasks such as are commonly used for pipe-molds. These flasks are ordinarily made in two similar parts or sections having oppositely-arranged hinging-lugs connected by transverse bolts, the bolt-openings in the lugs and the flaring apart of the latter beyond said bolt being such as to permit the free edges of the sections being swung apart sufliciently to open the flask as required.
The main object of my invention is to pro-- vide an improved hinge construction which will avoid the obviously objectionable looseness and play incident to thus connecting the flask-sections and which will permit accurate adjustment of the sections and insure their movement to uniform relative position.
The invention is fully described in connection with the accompanying drawings, and the novel features are specifically pointed out in the'claims.
Figure 1 is an elevation of a pipe-flask embodying my improved hinge construction, a portion of the near section being broken away, so as to show an inside view of the other section. Fig. 2 is a cross-sectional view showing the two sections of the flask in closed position, but with the pivotal retaining-sleeve, which serves to hinge them together, removed. Fig. 3 is an enlarged sectional view of the completed hinge, taken on the linewwofFigs. 1 and 2.
A and A are similar sections of a two-part twin flask for pipe-molding; Each section is formed with a hinging-lug 1 equidistant from the opposite ends and arranged opposite each other when the sections are placed together, as indicated in Fig. 2. Each lug is formed with a boss portion 2, abutting a similar boss portion on the opposite lug of the other section, so as to jointly form a pivoting-boss having its center at the pivotal axis 3, which axis lies in the meeting plane 4 4 of the two sections, Concentric with said boss 1 provide on each lug, as shown, a collar portion 5, and at the pivotal axis 3 is formed a central opening for the passage of a bolt 6, as hereinafter described.
The meeting faces of the lugs 1- lie in the meeting plane 4 4 of the two sections as far out as the pivotal axis 3; but beyond said axis the opposing face portions 7 7 of the lugs are inclined outward from said plane, so as to permit of a limited spreading of the free edges of the sections, as required, by turning upon said axis.
To complete the hinge, I provide a pivotal sleeve or cup 8, the inner diameter of which is such as to nicely fit over and hold together the abutted boss portions 2 2. The annular face 9 of this sleeve, as shown, is drawn toward the inner lug-face 10, forming the base of the boss portions, by means of the bolt 6, which extends through the axial opening 3in the lug and through the centrally-apertured outer plate of the sleeve, thus firmly retaining the latter upon the parted boss 2 2 and securely holding the hinged flask-sections in fixed relative position longitudinally.
The convenience with which the sections may be properly hinged together and the accuracy with which they return to normal position in closing are important advantages of my improved hinge construction.
The preferred construction shown and specifically described may obviously be modified without departing from my invention.
What I claim is l. A flask comprising hinged sections formed with similar oppositely-arranged hing- ,ing-lugs having abutting pivotal boss portions,
a pivotal sleeve inclosing said abutted boss portions, and retaining means for said sleeve.
2. A flask comprising hinged sections formed with similar oppositely-arranged hinging-lugs havingabutting pivotal boss portions, a pivotal sleeve inclosing said abutted boss portions, and a pivotal bolt passing through said abutted boss portions and serving to retain said sleeve upon the latter.
3. A flask comprising similar sections formed With oppositely-arranged hinging-lugs having pivotal boss portions, said lugs being flared away from the meeting plane of the sections beyond the pivotal axis to permit a limited swing of the sections on said. axis, and a pivotal retaining-sleeve inclosing said boss portions.
4. A flask comprising similar sections formed with o p positelyarranged hinging-lu gs having pivotal boss portions, and concentric collar portions outside of said boss portions, said lugs being flared away from the meeting plane of the sections beyond the pivotal axis, and a pivotal retaining-sleeve inclosing said boss portions and loosely inclosed by said collar portions.
5. A flask comprising similar sections formed with oppositely-arranged hinging-lugs having pivotal boss portions, and concentric collar portions outside of said boss portions, said lugs being flared away from the meeting plane of the sections beyond the pivotal axis, a pivotal sleeve inclosing said boss portions and loosely inclosed by said collar portions, and a pivotal retaining-bolt.
In testimony whereof I aifix my signature in the presence of two witnesses.
SAMUEL REICHWEIN.
