MEANS FOR FORMINGTHREADED-OPENINGS IN CASTING.
Specification of Letters Patent.
Batented March 9, 1909.
Application filed November 8. 1907. Serial No. 401,333.
To (171 whom. it may concern:
Be it known that I, JosEPn BEDELL, a citizen ofthe United States, residing at Ronsselaer, in the county of Reusselaer and State of New York, have invented. certain new and useful Improvements in Means for Forming Threaded Openings in'Castings, oi which the following is a specification.
My invention relates to improvements in means for forming threaded openings in :astings.
With certain castings it is difficult to thread an opening in particular places because of the inconvenience of using a drill and a tap. Furthermore in order to reduce the cost of the castings having threaded openihgs, I have found it expedient and practical to insert what I shall hereinafter term a shell formed by a piece of appropriately shaped wire, and placing it in the mold, and fusing it with the metal forming the casting. may be formed from wire, ed to receive a screw or bolt properly shap particular pitch, and is supported in aving a the mold 1n a manner best suited for the convenience of the artisan.
The invention relates to the details of construction and arrangement of parts to he hereinafter referred to and particularly pointed out in the claims.
In the drawingsFigure 1 is a vertical section of my invention in connection with a screw. Fig: 2 is a detailsectional perspective view of the improved shell. Fig. 3 is a detail section of a shell formed interiorly to correspond with an ordinary bolt thread. Fig. 4 is a view of a slightly different form of my invention. Fig. 5 is a plan view of the same. Fig. 6 is a perspective view of a further form of the invention. Figs. 7 and 8, illustrate side and top views respectively of a shell andsuppprt formed from a single piece of metal.
Broadly stated the invention comprehends a plurality of spirals forming a shell to be embedded in a casting to providefi'a screw thread, but in addition I have also devised special means for holding the shell in position when casting, which means with the shell becomes a part of the finished product.
The numeral 1, indicates a spirally arranged shell, somewhat inthe nature of a close spring, the convolutions of which are arranged a jacent each other and are of a determinate pite'h i l i i i I i 1 However, it is advisable to insure accuracy,
to provide a support, and as it is possible to arrange this feature in a number of different ways, I have shown several. For instance in Fig. 4, theupper art of the" shell 1, is provided with a thin siieet metal cap, 3, having a tubular portion 4, and an overhanging flange 5, with spurs 6. The cap serves as a means for holding the shell, and the spurs become emhedded in the sand.
The form shown in Figs. 7 and 8,-is similar to the construction shown in Fi' s 4 and 5, except that the overhanging ange 6, is formed from the same iece' of metal as the shell. After the shell isof the desired length, the wire is bent into a series of flat coils at right angles to the disposition of those of said shell, as clearly shown in the drawing. I
For certain shells, it is essential that an elongated support be provided, and to meet this contingency, I have provided a support, such as shown in Fig. 6. In this form of mv -.im-'ention, 7, indicates a sheet metal band bent at SS, to provide outwardly extending members 9-9, having openings ill--10, in which a tubular member is mounted. The tubular member may have openings 11, to expose the outer side of the shell, and through which the molten metal forming the casting will (low. The molten metal flowing into the 0 enings will contact with the shell and fuse thereto.
in use the shell is placed in a suitable recess inv the pattern, and is packed with core composition, and when the pattern is removed, the shell remains supported in the mold, and as has been indicated heretofore the shell may or may not have the support, this depending altogether on the circumstances as to the character of thread desired, the length of the same, and other incidental features known to the trade. molten metal is poured into the mold, it flows around the shell and support, and fuses, forming practically a unit, and producing a thread in the casting, without the necessity of drilling and tapping as now practiced.
If it is found desirable, the innerface ofv hen the the wire from which the shell is formed may be shaped to accommodate threads of particular shapes, as shownin Fig. 3, and ob-' viously in winding the wire the pitch may be .altered to suit the screw or bolt which is to cooperate with the thread.
e Inasmuch as many minor changes may be made without departing from the spirit and sco e of my improvement, I desire it to be on erstood that I reserve the right to such as come within the purview of the invention.
Having now described my invention,what I. claim is 1. An improved article of manufacture, designed for forming threaded openings in castlngs, comprisin a shell formed from a singlestrip of meta in a series of coils, the
,inner diameter of the coils being beveled to accommodate a thread of a bolt or screw.
' 2. An article of manufacture designed for forming threaded openings in castings comprising a shell formed of a series of coils, and
a thin metal sup ort on the outside of the shell for holding t e latter.
3. An article of manufacture designed for forming threaded openings ,in castings comprisin a shell formed of a single piece of metal by coiling to provide a threaded 0 ening, a su port for the shell, said support av ing a tu ular extension and a flange extend ing outwardly from the tubular extension.
4. An article of manufacture, designed for forming threaded openings in castings, com-- prising a shell formed of a single piece of metal by coiling to provide a threaded opening-and a flange at one end of the shell, the shell and flange bein formed of metal which will fuse with the mo ten metal.
5. An article of manufacture, designed for forming threaded openings in castings, comprising a shell formed of a continuous iece of metal to TOVIdQ a series of coils, an a support for. t e shell, said support comprising a thin sheet of metal bent to provide extended 1 members, and a tubular extension connecting the members and enga ing the shell.
6. As an im roved artic e of manufacture, designed for orming threaded openings in castings, a shell formed of a continuous piece of metal to produce a series of coils, and a support for the shell, said support comprising a membef connected by a tubular extension which engages the shell, said extension being formed with openings to expose a part of the shell.
7. As an article of manufacture, designed for forming threaded openings in castings, a
' shell formed of a series of coils,.a support fltherefor, s'aid support having .a tubular extension formed with openings to expose the shell.
8. An article forming threaded openings in castings, comprising a shell formed of a series of coils, av
support therefor, and a rejection extending ,beyond the outer face 0 the support.
9. As a new article of manufacture, designed for forming threaded openings in castings, a shell formed of a series of coils, a support on the outside of the shell, said support aving a series of openings to expose the shell.
In testimony whereof I aflix my signature in presence of two Witnesses.
