STAVE AND SHINGLE SAWiNG MACHINE.

SPACIFICATION forming part of Letters Patent No. 292,309, dated January 22, 1884.

Application filed May 5 1883. (No model J i In hearings in the middle part of the frame lb aZl IU7L0777/ it may concern: I I

Be it known that I, WILLIAM JACKSON HENDERSON, of N aylor, in the county of Lowndes and State of Georgia, have invented a new and useful Improvement in Stave and Shingle Machines, of which the followingis a full, clear, and exact description.

Reference is tobe had to the accompanying .drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1, Sheet 1, is a plan View of my improvement arranged for beveling and bilging Fig. 2, Sheet 1, is a front elevation of the same. Fig. 3, Sheet 1, is a sectional end elevation of the same, taken through the broken line xx, Fig. '1. plan view of the same arranged for sawing shingles. Fig. 5, Sheet 2, is a front elevation of the same, part being broken away. Fig. 6, Sheet 2, isan end elevation of the same, the carriage" and carriage-table being shown in section.

The object of this invention is to promote convenience and accuracy in beveling and bilging staves, sawing shingles, and doing other sawing. The invention consists in astave andshinglc machine constructed with a frame provided with a table, a saw, and a carriage-table having a curved groove and a straight groove, to receive and guide the carriages as they are moved forward and back. The stave-carrying carriage is provided with inclined blocks, to support the staves at a lateral inclination, adjustable knees for holding the staves to the saw, and a rocking rod provided with rigid arms for adjusting the knees, so that the staves will receive the desired bevel and bilge. I11 the machine-table are formed grooves, to

receive and hold the heads of the bolts that secure the gage-bar adjustabl y to the said table, and to the said bar is attached a gagescrew, so that the shingle-block can be readily adjusted into such a position as will give the required thickness and taper to the shingles,

Fig. 4, Sheet 2, is a A revolves the mandrel G, to the forward end of which is attached the saw D.

To the middle part of the mandrel G is attached a pulley, E, to receive the drivingbelt F. e

The lower part of the saw D is inclosed in a box or spout, G, which receives the sawdust and conducts it to the outside of the machine, to protect the belt F from the said sawdust.

To the front of the machine A is attached the carriage-tableH, in the outer part of the upper side of which is formed a curved groove,

I, with its convex side toward the saw D, and in the middle part of the said carriage-table is formed a straight groove, J, parallel with the said saw D.

K is the stave-carriage, which slides upon the table H, and has upon its lower side a tongue, L, curved to fit into and slide along the curved groove I, so that the carriage K will travel in a curved path as it moves forward and back uponthe table H.

To the upper side of the rear end of, the carriage K is attached a head-block, M, to which is attached ahandle, N, for convenience in operating the said carriage.

- To the inner part of the upper side of the carriage K are attached four (more or. less) in clined blocks, 0, of such an inclination as will to-or formed upon the upper side of the carriage K slide the horizontal parts of the knees 1?, against the upright parts of which rest the outer edges of the staves while their inner edges are being sawed.-

To the horizontal partof the knees I? are pivoted the ends of arms Q, formed upon or rigidly attached to the rod R, which rocks in bearings S, attached to the carriage K.

To the rear end of the rod R is attached, or upon it is formed, an arm or lever, T, which projects upward through akeeper, U, attached to the inner side of the head-block M, so that the said lever T can be readily reached and operated by a finger of the hand that grasps the handle N, to rock the rod R and move the ICO knees P in and out to vary the out of the staves.

In using the machine for beveling and bilging staves, the knees P are moved outward, more or less, staves are laid upon the inclined blocks 0, with their outer edges resting against the upright parts of the said knees P. The carriage K is then moved forward by hand and the saw D will bevel and bilge that edge of the staves accurately. The carriage K is then drawn back, the knees I? are moved inward, the stave/s are turned end for end and placed upon the inclined blocks 0, and the carriage is again moved forward, completing the beveling and bilging of the staves. The carriage K is then drawn back and the staves are removed and replaced by another set.

V is theshin gle-carri age, which has a straight tongue, \V, upon its lower side, to fit into and slide along the straight groove J. The carriageVis provided at its rear end with a headblock, X, and handle Y, in the same manner as the carriage K.

Upon the forward part of the upper side of the table B is placed a gage-bar, Z, which is secured adj ustably to the said table Bbybolts a, the heads of which enter and slide in T- grooves 12 in the said table B, so that the said bar can be adjusted by loosening the nuts of the bolts a.

In a screw-hole in the gage-bar Z is placed a gage-screw, c, with its forward end projecting at the forward side of the said gage-bar Z in such a position as to be a little forward gfi oflthe head-block X when the carriage V is are to be sawed is, laid upon the carriage V,

with the forward end of its forward side restlug against the side of the gage-bar Z, and the rear part of its forward side resting against the gage-screw c. The carriage V is then moved forward and back until the block is half sawed up, when the block is turned end for end until it is wholly sawed up, so that there will be no waste of material.

The machine can also be used for sawing laths, fruit-crate slats, and for other sawing.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A stave and shingle machine constructed substantially as herein shown and described, and consisting of the frame, the table and the saw, the carriage-table provided with a curved groove and a straight-groove, and the carriage provided with theinelined supporting-blocks, the adjustable knees, andthe rod having rigid arms, as set forth.

2. In a stave and shingle machine, the combination, with the frame A, of the carriage table H, provided with a curved groove, I, and a straight groove, J, substantially as herein shown and described, to adapt thesaid table to receive and guide the carriage, as set forth.

3. In a stave and shingle machine, the combination, with the frame A and the carriage table H, having curved groove 1, of the carriage K, having head-block M and handle N, the inclined supporting-blocks O, the adjustable kneesI, and the rod R, having rigid arms Q and T, substantially as herein shown and described, whereby the staves will be supported and carried to and past the saw in proper position, as set forth.

4. In a stave and shingle machine, the combination, with the table B, having grooves b, of the gage-bar Z, the bolts a, and the gagescrew 0, substantially as herein shown and described, whereby the shingle-bloek can be adjusted upon the earriagc to give shingles of any desired thickness and taper, as set forth.
