DEVICE FOR GROOVING AND CUTTING VENEBRS.

HENRY O. VARD, OF GREENFIELD, TENNESSEE.

DEVICE FOR GROOVING AND CUTTING VEN EERS.

SPECIFICATION forming part of Letters Patent No. 390,271, dated October 2, 1888.

Application filed May 23, 1888. Serial No. 274,792. (No model.)

To all whom it may concern.-

- Be it known that l, HENRY O. WARD, a citi zen of the United States, residing at Greenfield, in the county of Weakleyand State of Tennessee, have invented certain new and useful Improvements in Devices forGrooving and Cutting Veneers; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a device for grooving and spurring veneers for fruit-boxes, baskets, and other similar purposes; and the object of my invention is to provide an adjustable device that will groove and cut the veneers accurately and any required length as they are cut from the log by a rotary veneermachine. I attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure l is a perspective view of the device attached to the adjustable bar of rotary veneermachine and in a position for use. Fig. 2 is a perspective view of the shoes or holders of the grooving and cutting instruments with the instruments or cutters detached. Fig. 3 is a similar view with the cutters adjusted in the shoe. Fig. 4 is a perspective view of the cutters or groovers detached from the shoes or holders. Fig. 5 is a cross-sectional view of the device attached to the bar that contains the cutter of veneer-machine and in position for use.

A designates the shoe, which is constructed with the orifices a and aand the slot at or the hole a", and it is provided with the set-screws a. The shoes A are rigidly secured to the shafts B and O by means of said shafts passing through the orifices a and a, respectively, after which the set-screws a are tightened, which rigidly secures said shoes to the shafts B and C. By loosening the set-screws a" the shoes A can be slipped to any desired point on the shafts B and 0; hence it is readily seen that the shoes A may be made to assume a close, medium, or distant position to each other on said shafts, accordingly as it is desired to cut and groove the veneers.

The rotary shaft B is made of iron, and has the bearings b on the top of the sliding feedlancetpoint or otherwise.

and in an instant draw back the shoes. The

. groovers and cutters are then out of position for use. In another instant they can as easily be thrown forward, when they resume operation.

D represents the groover, which is made of 6 steel and of any required size, the end of which is V-shaped for the purpose of cutting a semicircular groove. This instrument or groover is adapted to the slot a in the shoe A, and is rigidly held in position by means of a set-screw, a. It can be made to cut a groove any depth, accordingly as it is set.

E is the knife for cutting or spurring the veneers, and it is made to fit into the hole a of the shoe A. It is likewise held in position and regulated by means of a sct-screw, a. The cutters E may be made with a straight Said groovers and cutters are arranged in the particular manner shown and described specially with a view of performing their work effectually and of being easily detached from the shoe when it is necessary to sharpen them.

It will be observed that as the shaft B rotates and is located upon the sliding bar over the crosshead that carries the knife G of rotary veneer-machine it will at all times, as the log is being cut away, adapt itself equally as well to the veneers, because it moves forward or is fed up the same as the knife. In fact, there is only one point where the shaft B when in its normal position assumes a proper relation to the center of the log and will enable the groovers and cutters in the shoes Ato cut equally as well when the log is large as when it is small. This point is where the shaft Bis located. If it is desired to cut the veneers withoutgrooves, &c., the shaft B can be thrown back, and my device is completely out of the way; or it can be detached simply by removing its adjustable bearings b. An y number of shoes may be used, asthe length of the shaft B may require, to groove and cut veneers; or two groovers may be put on one shoeone on each sidewhen it is desirous to have them close together for certain kinds of work.

'- My device is practical, simple, and effectual, and when once in operation requires no more attention than the occasional sharpening of the knives used in grooving and cutting.

Having fully described my device, what I claim asnew, and desire to secure by Letters Patent, is

Inadevice forgrooving and spurring veneers, the combination of the shoes A, the \l-shaped and straight lancet-pointed groovers and cutters located in said shoes, the set-screws by 15 which said groovers and cutters are secured and regulated, the shafts B and C, passing through the lower and upper ends, respectively, of said shoes, and the set-screws for securing and regulating said shoes upon said 20 shafts, substantially as described and shown.

In testimony whereof I affix my signaturein presence of two witnesses.

HENRY O. WARD.
