Improvement in Flue Expanders.
No. 121,514. Patentednec.5,1a71.
'UNITED STATES PATENT OFFICE.
IRA S. HAMILTON, OF HAMILTON, OHIO, ASSIGNOR- TO HIMSELF AND OWENS, LANE, DYER & OO., OF SAME PLACE.
lMPROVEMENT IN FLUE-EXPANDERS.
Specification forming part of Letters Patent No. 121,514, dated December 5, 1871.
To all whom it may concern:
Beit known that I, IRA S. HAMILTON, of Haniilton, in the county of Butler and State of Ohio, have invented a certain Improvement in Flue- Expanders; and I do hereby declare that the following is a full, clear, and exact description thereof, referen cebeinghad to the accompanying drawing making a part of this specification, in whic Figure 1 is a longitudinal section of the tool complete. Fig. 2 is a transverse section 011 a plane indicated by line a' a' of Fig. 1. Fig. 3 is a sectional elevation ofthe expanding rollers, the cap in which they operate, and a portion of the tapering mandrel.
The same letters of reference are employed in all the gures in the designation of identica-l parts.
This invention, relating to that class of tools which is used for setting the lues in the fluesheets of steam-generators, consists in the combination of a tapering mandrel; a series of swaging-rollers, every alternate one of which is constructed with a bead at each end fitting grooves in the others, and which are arranged to form a circle around the mandrel 5 and a cylindrical socket for revolving the rollers bodily around the mandrel and holding them temporarily in place until they begin to form grooves in the flue, when they will be supported between the mandrel and the wall of the flue independent ofthe socket. The object of my invention is to dispense with the necessity of littin g the swaging-rollers in bearings in the socket, as has been customary heretofore, and in this way to simplify and cheapen the construction of tools of this class.
In the example illustrated in the drawing six swaging-rollers are employed, those marked A being constructed with a bead or rounded collar, a, at each end, while those marked A have grooves a corresponding with the beads on the former. Every one of the rollers terminates at one end in a short neck, b, with a collar, b. The rollers are arranged in a circle around the tapering mandrel B, which is passed through them after they have been inserted in elongated slots in the head G of the cylindrical socket C, with their necks, as shown. The collar on the end of the neck prevents the withdrawal of any one of the rollers until the mandrel is removed. The bore ofthe socket is such as to tit over the end of the iiue to be set, and it should be so constructed that it can be readily turned on the flue by means of a wrench or other suitable device. The tapering mandrel terminates at the smaller end in a cylindrical screw-threaded bar, to work in a nut, D, which is held stationary at any desired point in the iiue by means of a dog, D', the latter iitting in an inclined groove in the nut so as to bind on the liue as the nut is drawn outward slightly in arranging the tool for operation. The opposite end of the mandrel is squared for the reception of a crank or wrench to feed it forward and force the rollers gradually apart as the swaging proceeds. A sufficient number of rollers should be employed to form a belt around the mandrel and cause the beads on one to extend into the grooves of its neighbors. In this manner they form a bearing one for the other and prevent individual longitudinal motion before that is more effectually prevented by the formation of grooves in the lue by the beading-rollers.
What I claim as my invention, and desire to secure by Letters Patent, is-
The combination of the tapering mandrel B, swaging-rollers A A, constructed as described and arranged to form a belt around the mandrel for mutual support, and the socket C C', substantially as and for the purpose set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
IRA S. HAMILTON.
