Letters Patent No. 108,357, dated October 18, 1870.
l IMPROVEMENTV IN WHlFFLETREE-COUPLINGS.
The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern? Beit known that I1 Jnrins Ivns, of Mount Car'- mel, in the county of New Haven and State of Gonnectcut, have invented'an Improved Whiflietree- Coupling; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, in whichare fitted together, and the end of Va hollow journal,A
which is formed on one of the parts, is expanded, Va
permanent connection will be "effected,
I am aware that, prior to my invention, whifiietreecouplings were made, which resemble mine insome respects, when iinishechbut such couplingswere made` by irst casting one part with a countersunk hole through it, and then placing such part into a liaSk, and casting the other part onto it, so that the central part' of the last extends into and lls the circular space left in the first. 'Couplings of this kindare expensive to make, and are otherwise objectionable. fl`he followingis a description of my mode 'of producing whifdetree-conplings:
journal, g, the' end oi' which I prefer to notch, as
shown in figs. 3 and 4, for a reason hereinafter explained.
The circular hole h, through the center of this journal is tapered, so that the notched end of the Fhub is the thickest. Y
The notcheswhich are across the end ofthe journalg, may be made by means of a file, or inrany other desirable manner. Y Having thus produced the two parts constituting the whifletree-coupling of malleable iron, I adjust themV together, as shown in iig. 3, and with a steel pin Vof proper size,-I spread the notched end of the journal g, in Athe 4flaring hub e, thus forming a rivethead on the journal, and uniting the twoplates top gether permanently, sol that they have free articulation.- *1- 'I he notches in the journal g permit it to expand .-,no're freely, without liability of fracture.
When the coupling is in use, a bolt passes through the-hole `which is through the journal,-which `bolt will prevent the expanded end of the latter from closing again.
It will be seen, fromthe above description, that one l part, B, of thelcoupling has the journal g cast on it, byf which the two vparts are connected together by a' subsequent process of spreading the end of this journal. I thus accomplish the permanent connection of the two parts, which are cast separately.
This mode of connecting.whiiletreefplates :will be found very useful for connecting together the blades of large shears, as the joint can be set up very read,- ily, should itat any time become loose.
vlhe same -process may also be applied connecting' many other articles of manufacture.
Having described my invention,
What I claim as new, and desire to secure by Letters Patent, is'- 'The two parts A'and'B, cast separately, and jointed by means of thehub g on one part, 4which has its end expanded into a flaring hole `through the other part, substantially as described.
