Processes 0f Finishing Sheet-Metal Butts.

UNITED STATES PATENT OFFICE.
IMPROVEMENT IN PROCESSES OF FINISHING SHEET-METAL BUTTS.
Specification forming part of Letters Patent Nol34,029, dated December 17, 1872.
's transverse section through the head on line This invention relates to an improvement in finishing the faces and joint of sheet-metal butts.
Heretofore this has been done by polishing wheels or similar devices, and it has been impossible to make the joint perfectly cyliudrical, and the process of finishing involves no incousiderable amount of labor.
The difliculties mentioned and a large proportion of the expense of finishing are, by my invention, overcome; and it consists in a. bed or guide on which is arranged transversely a. stationary burnisher, the form of the burnisher corresponding to the faces and joint of the hinge when open to their full extent, and combined with a roll on the reverse side, which bears the butt up against the burnisher as the butt is forced through.
A is the bed, with guides B arranged upon each side and distant from each other the width of the butt, or a little more, when fully open. Near one end of this bed the burnisher U is firmly fixed. The under surface of this burnisher or finisher corresponds to the faces of the two leaves of the butt when fully open,
' and at the center, as at D, with the barrel or joint between the two leaves. Beneath this hnrnisher C is arranged a wheel or roll, E, the periphery of which corresponds to the reverse or back side of the two leaves when open, as in Fig. 2. This wheel is supported by suitable springs F, or equivalent device, which will bear the wheel up against the butt, but yield for slight difierences in the thickness of the metal. The butt is represented in Fig. 2 in solid black.
The butt is arranged upon the bed Abetween the guides B as denoted in Fig. 1; then, by any suitahie follower, the butt is forced through the burnisher 0, this burnisher or finisher acting upon the faces of the leaves to finish the surface, and the central part of the finisher will shape the barrel or joint, working it into the exact central position and perfect cylindrical form, so that in any position the joint will be perfect.
In practice I find the ordinary punchingpress to be a. good if not the best means for operating this device, by adjusting the bed A verticall'y beneath the slide of the press, and then, with a follower in the slide working downward to drive the butt through the finisher; but the means of driving the butt is no part of my invention.
I claim as my invention- The device herein described for iinishin" the face of butt-hinges, consisting of the finisher O and the bearing'surface E upon the reverse side, combined with a suitable bed or guide, A, for presenting the butt to the finisher, substantially as set forth.
