UNITED STATES PATENT OEEICE.

HORACE BAKER, OF OORTIJAND, NEW YORK.

Specification forming part of Letters Patent No. 58,754, dated October 16, 1866.

To all 'whom it mayV concern:

Be it known that I, HORACE BAKER, ot' Cortland village, Gortlan d county, and State of New York,have invented a new and useful Improvement in Machines for Making'Churns; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being' had to the annexed drawings, making part of this specification, in which-- Figure l is a perspective view. Fig. 2 is a vertical section. Fig. 3 is a plan of the swinging frame; Fig. 4, asection of part of the machine; Fig. 5, a section of the fan; Fig. 6, a view of the inside plane; Fig. 7, a section of the same. v

In the several ligures I employ the same letters when referring to identical parts.

The following description will enable persons skilled in the art to make and operate my machine.

A is the main frame and bench upon which the machinery is carried. It will. be framed as may be required for the purpose. The mechanism is driven by belts from the drum B, placed under the bench.

The churn or cask is finished on the lathe arranged for the purpose of nishing it by planing the outside and inside surfaces at the same time. The outside surface is planed by a plane held in the hands of the operator against the side of the churn. The inside is planed automatically by devices I will proceed to explain.

One end of the churn is supported on the adjustable head-plate C, which slides on ways moved by the lever I). On this plate, and also on a corresponding ixed plate, C', at the opposite end of the churn, I erect a standard, E, supporting a ring, F, which serves as an annular guide for the pulley G. This pulley is a ring of metal, having on one side a circular groove of the width and depth of the annular guide F, in which it tits, so as to permit the pulley to turn easily. The pulley is driven by a belt.

On the exterior of the annular guide F is a groove which receives the projecting point G', which retains the pulley on the ring. The churn, being inserted in and attached to the inner face of the annular pulley G, turns with the revolutions of these pulleys, which are at tached at each end of the churn.

The inside of the churn is turned or planed by the plane I, which is hung on the guidingbar H, which, passing through a notch in the standard Hl, guides the plane along the surface of the churn. The guiding bar H is curved, so that the bar shall have the curvature intended to be given to the internal longitudinal face of the churn. On the Linder side of the bar H is a rack, H2, Vwhich receives the teeth of the feedpinion II3 on the end of the shaft K, which is turned by a pinion, K', and endless screw L on a shaft, L, which receives its motion from the drum B by belt and pulley. The motion of the pinion H3 regulates the feed given to the bar H and plane I.

A flexible tube, M, through which is conducted a blast from the fan N, is used for blowing the shavings as made from the churn.

The staves are eut to the proper form by the knives O on the revolving annular wheel O, which is carried upon a vertical shaft and driven by belts from the drum B.

There are a double series of knives or cut ters, O/ one set in the external and another set in the internal edge ofthe annular wheel O.

I is the swinging frame, in which the staves are secured by the pressure of the arc P3, which is pressed by the eccentric-headed lever l?Z against the inside of the staves. The rod P1 is placed diagonally on the swinging frame, and, when laid upon the fra-me, is held in place by the catches Q. These catches are bent, as shown in Fig. I, so that when the swinging frame is laid upon the annular wheel O the transverse rod P will lie in the rst loop on one side and the last loop in the other catch Q, and when turned over will in like manner be received by the other loops. The catches and the swinging frame rest upon the plate R, which ha-s a slot, R', through which the shaft of the annular wheel O passes. This plate slides freely upon flanges projecting from the inner face of the side pieces ofthe frame S.

The outside set of knives, O', is used for partly finishing the rough faces ofthe staves. They are finished on the inside set of knives. When finished Von one side they are brought in contact with the knives on the opposite face ofthe stave by reversing the swingingt'rame I).

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

1. The annular wheel O and knives O', in

combination With the 'Swingin g frame l?, when In testimony whereof I have signed my name if respectively constructed and arranged for use t0 this specification in the presence of two Subsubstantiallyas set forth. scribing witnesses.

2. The combination and arrangement of the f annular guide F and pulley G, for suspend- HORACE BAKER. ing and revolving the barrel of a churn, with the guide-bar H, carrying the plane I and Witnesses operated by an automatic feed, substantially GEO. F. HOLMES, e as set forth. R. D. KING.
