EBEE G. FLINT, OF SAGINAV, MICHIGAN.

BARREL-HOOP MACHINE.

SPECIFICATION forming part of Letters Patent' No. 268,395, dated December 5, 1882. Application filed September :2, 1882. i (No model.)

To all whom it may concern:

Be it known that I, EBEE C. FLINT, a citizen of the United States of America, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Barrel-Hoop Machines, of which the following is a specification, `reference being had therein vto the accompanying drawings.

This invention has relation to improvements in machines for cutting barrel-hoops; and it consists in the novel construction and arrangement ofthe parts, as will be hereinafter d'escribed. p

The annexed drawings, to which reference is made,fully illustrate my invention, inwhich- Figure l represents a vertical sectional view of my hoop-machine. Fig. 2 represents a front view of thc same, and Fig. 3 is a top or plan view.

The letter A designates two uprights, which are provided on their inner faces with vertical guideways c a, in which slides a frame, B, that carries the knives b b b', that are operated by a pitman pivoted to the frame and connected to an eccentric secured to a horizontal shaft carrying pinion and gear-wheel, which will'be further explained.

C designates the bed-timber, which -is secured to the uprights, and is provided on its upper surface with grooves cc, arranged crosswise the same, in which moves a tiltingframe, o', that is pivoted at its ends to the bed-timber C. Said bed-timberis also provided onits edge and upper surface, next to the knife-carrying frame, with a transverse groove, c2, in which are placed metal strips c3, that are secured in place by means of a Wedge,c4, driven in rear or' said strips.

D indicates a screw-threaded rod, the upper end of which is removably pivoted in bearings d, secured to the center ofthe tilting frame c', while the lower or `opposite end connects with a female threaded head of an adjustable rod, d', that is forked at its lower end, in which is placed a small wheel or roller, d2, that is operated upon by a cam, d3, secured to the face of a gear-wheel, d4. Said gear-wheel receives its motion from a pinion, d6, secured to the horizontal shaft d5, that operates the knifeframe aforesaid.

E designates a foot-treadle, hinged at e to Jthe licor, and provided with a lug, e', at its free end, that b ears against a spring-pawl, c2, that engages the inner edge of the rod d for the purpose of d isengaging the said rod from the cam d8 on the gear-wheel d, and when thus disengaged the foot-treadle is held by its free end by means of a spring-catch, e3, pivoted to the bedLtimber aforesaid. Said adjustable rod carrying the roller in its lower end has its forward, backward, and vertical movement in a forked guide-strip, e4, secured to the machine, and between the lower end of said rod and the machine-frame is interposed a spring, e5, one endvof which is secured to said frame, and the opposite end is connected to the roller end of the adjustable headed rod d', thus serving to keep the rollerin engagement with the cam d3 while the tilting frame is working.

Having thus described the different parts of which my hoop-cutting machine is constructed, I will proceed and explain the manner in which the same is operated.

Power is applied to the horizontal shaft d5,

which is mounted in suitable bearings, which gives motion to the eccentricf, and by means of the pitman f2 the knife-carrying frame receives a vertical or up-and-down movement, carrying therewith the main cutting-knife b and the two lapping-knives b b', which latter are placed one on each side of the frame, as shown in Fig. 2 ofthe drawings. wood to be cut or beveled is rst pointed and then laid upon the bed-timber U and over the The blank strip of tilting frame o', with the edge to be beveled close to the vertical frame carrying the knives. At the same time the pinion d6 gives motion to the gear-wheel, and by its cam d8 operates the adjustable rod d by said roller traveling upon the cam, and thus tilting the frame at the proper ICO will be observed that by means of the foottreadle the parts for operating the tilting frame may be disengaged at pleasure by the operator, and the pitch 0r slant of said tilting' frame may be increased or decreased by means of the adjnstable rods herein described, thereby enablin g the operator to cnt an y desired bevel on the strip of Wood; and, again, bymy construction of the bed-timber the strips of metal protect the Wear of the edge of said timber next to the knives, and when the hoop leaves the machine te allow another blank to take its place and go through the same operation the hoop is finished.

ltdesired, a gage may be pnt upon the knifeframe7 as shown atfin the drawings.

What I claim, and desire to secure by Letters Patent, is-

.In testimony whereof I affix my signature in 3o presence of two witnesses.p
