UNITE IVILLIAM MAGUIRE, OF CINCINNATI, OHIO.

MACHINE FOR JOINTING STAVES.

Specification of Lettersl Patent No. 7,886, dated January '7, 1851.

T all whom 25 may concern Be it known that I, IVILLIAM MAGUIRE, of Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Barrel Machinery; and I do hereby declare the following to be a full, clear, and exact description of the nature,

construction, and operation thereof, reiter-A ence being had to the annexed drawings, making part of this speciication.

My invention consists in apparatus for j ointing the staves.

Figure 1 is a longitudinal elevation of the stave jointing apparatus. Fig. 2 is an end elevation of the stave jointing apparatus; Fig. 3, a portion of the circular rest-showing the manner in which the handles 7c are retained by the springs j; and also a portion of the sliding frame c with the projecting arm 5.

Like letters refer to the same parts in the several figures.

a is a frame of wood. Journaling within this trame is a set oi" rollers b supporting a carriage c in which is journaled a large wheel or circular rest constructed as follows.

l is an outer rim or ring, and e an inner one concentric with the former.

f are a number of spokes, which divide the rim CZ into as many equal compartments.

g are stationary catches, and z, are sliding catches, which terminating in racks 7L', can be either protruded from or retracted toward the center of the wheel by pinions 6; and the springs j pressing upon the handles 7c, maintain the retraction of the racks.

Z are blocks aiiixed to the perimeter of t-he wheel midway between the spokes f.

One end of the stave to be jointed is inserted under a stationary catch g, and the other end under the adjoining sliding catch h, the latter having been previously protracted for that purpose. The ra-ck being then retracted by the pinion and retained to its position by the springs j acting on the handles Z0 of the pinions, the stave by this process is brought and held upon the wheel rim, to the curve which it possesses in the Cask. Each spoke terminates in a pair of cheeks m traversed by a pin n.

The carriage in which the wheel is journaled, has a reciprocating motion imported to it by the pitman o which connects it with the rotating arm p, upon a shaft g receiving mot-ion from the driving pulley r. A secondary pitman s connected with the pitman 0,

actuates a sliding crotch represented by dotted lines t, which grasping a pin n on the wheel, prevents the rotation of the latter while moving in the direction of the upper arrow'. Then the wheel has reached the end of its stroke the crotch retires, and another crotch u risingl through the floor grasps another pin, and thereby compels the wheel to rotate the distance of two consecutive spokes during its return in direction of lower arrow. This last named crotch u is actuated by a lever o, set in motion by a rotating pin w, which derives its motion from the driving pulley.

a: :U are blocks, capable of being advanced toward or -drawn from one another, and bolted to the frame at the proper distance apart, according to the width required for the stave.

y g/ are two gates or frames which carry the rotating jointer bits or saws a. These gates y. are united to the blocks at their inner edge, by pivots; their rear edges being capable of being raised or lowered byscrews 3 according to the amount of flare or chamfer to be imparted to the stave joint. These jointing bits are driven by a system of belts and pulleys 4L connected with the driving pulley.

5 is an arm projecting` from the frame, which intercepting the handles of the pini ons-after thevleave the jointer liberate the former, and allow the stave to escape.

Operation as follows z-The stave to be reduced is placed upon a section of the large wheel for jointing, just as the wheel approaches the extremity of its stroke, and the wheel, in returning. passes the stave between 'winch k which proceeds from the pinions 6.

Having thus fully described the nature` construction and operation of my invention.I what I claim therein as new and original, and desire to secure by Letters Patent is The arrangement substantially as herein described, of a circular rest. having a sliding motion to and fro, in the plane of its taper according to the size and bilge of the 10 Cask.

In testimony whereof, I have hereunto set; my hand before two subscribing witnesses.

WILLIAM MAGUIRE.
