Description

UNITED STATES Patented June 2, 1903.
PATENT OFFICE.
AUGUST MERTES, OF`EMSWORTH, PENNSYLVANIA, ASSIGNOR TO COLONIAL Y COLUMN COMPANY, OF ALLEGI-IENY, PENNSYLVANIA, A PARTNERSHIP.
BUILT-UP COLUMN.l
SPECIFICATION forming part Of Letters Patent No. `730,191, dated June 2, 1903. Application filed October 9, 1902. Serial No. 126 ,607. (No model.)
To all whom it may concern: v
Be it known that I, AUGUST MERTES, of Emsworth, Allegheny county, Pennsylvania, have invented a new and useful Built-Up Column, of which the following is a full, clear, and exact description,`reference being had to the accompanying drawings, forming part of this specication, in which- Figure 1 is an end elevation of a built-upv wooden column constructed in accordance with my invention. Fig. 2 is a partial longitudinal section of the same, and Fig. .3 is a cross-section.
My invention relates to the class of columns which are built up of intertitting wooden staves and is designed to provide an improved method of securing the ends of the staves, whereby they are clamped together and firmly held in place.
In the drawings I show the column as composed of staves 2, each having at one edge a projecting tongue 3 and a groove 4 extending along the opposite edge. These tongues and grooves interfit in the manner shown, the parts being glued together in the usual manner to form the column. The manner of interitting the staves may be varied as desired. The end of the column is provided with an annular recess lhaving a beveled inner face,
and into this recess is driven a'wooden hoop 5, having a beveled inner face 6, which corresponds to the beveled face of the recess.
noted that the width of the wooden hoop or ring parallel with the axis of the column is much greater than the transverse thickness of the hoop atright angles to the axis. This,
together with the wedge action and the fact that no securing-screws are required, presents many advantages over-the former securing means for this purpose.
It is often desired to saw these columns apart lengthwise, and the use of my wooden hoop or ring does not'interfere with this 0peration.
Many variations may be made in the form and arrangement of the wooden ring without departing-from my invention.
I claiml.- A built-up column composed of wooden staves,"andA a wooden ring glued within an annular recess in the end of said column; substantially as described. A
2. A built-up column with Wooden staves having an end recess of greater depth than width, and a wooden hoop glued within and illing said annular recess; substantially as described. l
3. Abuilt-up column of wooden staves having an end recess with an inclined face and a wooden ring fitting in the recess and having a correspondingly-inclined face arranged to bindvthe staves together; substantially as described.
In testimony whereof I have hereunto set lmy hand. The hoop may be provided with a scarf-joint AUGUsrMER'rEs.
