MACHINE FOB., JOINTING STAVES.

Specification of Letters Patent No. 10,683, dated March 21, 1854. i

To all fr0/1,0m t may concern Be it known that I, ALEXANDER WILBUR, of Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Jointing Staves; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part thereof, in which- Figure 1 represents a side View of the machine; and Fig. 2, a vertical section through the center lof the swing frame, with a portion of the concave dressing wheel.

Similar letters in both figures denote like parts.

' The nat-ure of my invention relates to the method of joint-ing staves of variable widths, each with its requisite bilge, without adjusting the machine, it having a self-operating adjustment for each andevery width. Also in combination with the swing frame in which the stave is presented to the cutter wheel, the guides which move with it, for the purpose of holding the edge of the stave being dressed firmly to the wheel of cutters.

4To enable othersskilled in the art to make and use my invention, I will proceed to describe the same in connection with the drawings. v

The frame A, may be constructed inany well known substantial manner, so as to sup port a cutter wheel B, on a vertical shaft C, provided with a pulley D, over which a belt from any first mover may pass. The top face of the cutter wheel B, is concave and provided with any required number of cutters E, E, &c. At one side of the frame I arrange a swing frame F, into which the stave is placed to be presented to the cutter wheel. The staves arey not bent or sprung in the swing frame but lie perfectly straight, the concavity of the jointing wheel giving it the proper bilge. The swing frame F, has an axis or journal a which has no fixed bearing, but moves in a slot c, which is on the same plane with` theconcave surface of the jointing wheel.

Z is a shoulder, and e, a lip or projection on the end of the swing frame against and under which the stave is held, against 'the action lof the cutters, the distance between.

the axis a, of the swing frame, and the f pointl where the stave is held, being one half i v the `diameter of t-he `barrel for whichv the= stave isbeing dressed. A rod f, runs across the back of the swing frame permanently attached thereto, and the ends of this rod or bar pass into inclined staples or slots g, one at each side of the frame (though onel only is seen in the drawings); and behind the swing frame is a spring It, to throw it for- Ward and raise it up to receive or remove the stave. A bar z', one at each side of the swing frame is attached to the axis or rod a, and is made to slide in grooves cut in the pieces G, of the frame, and tothe ends of these bars z' are arranged two cross barsjy j, beveled off on their opposite faces, vand just far enough apart to admit the edge of the stavevto `be dressed, and prevent its moving in any other direction than vertically while being operated on. As these guide bars are connected to and move withthe swing frame,

they will be in place to receive any stave coming in to be dressed whether wide or It will be perceived from the description that there need be no waste of material, precontinues to descend, the rod f, in the in-` clined staples g, draws back the swing frame, the slot c admitting the axis a of the said frame to move back in the plane of the wheel, constantly changing the point of action on the concave, so that whether the stave be wide or narrow it has its requisite bilge, without any loss of material.

Having thus fully described the natu-re of my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

1, SO hanging the swing frame, which feeds up the :stave t0 the jntng Wheel, as to the Ontng Wheel or cutters substantially that staves of variable Wfdths may be (lressd as described.

with thebilve necessary or said Wdt ssl f stantally ase described. ALEXANDER WILBUR' .5Y 2. I alsov claim in combination With the VWitnesses:

swing frame the guides which move with it, A. B. STOUGHTON, for the purpose of firmly holding` the stave l SAML. GRUBB.
