'Y GEORGE WATT', 0F RICHMOND, VIRGINIA. Letters Patent No. 72,248, dated December 17, 1867. l
IMPROVEMENTA IN WHIPIL-TRBS.
TO ALL WHOM IT MAY CONCERN:
Be it known that I, GEORGE WA'rl, of Richmond, in the county of Henrico, and State of Virginia, have invented a new and useful Improvement in Whii'lleTr-ees; and I do hereby declare the following to be a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, which are made a part of this specification. i
The subject ofthe present invention is awhile-tree, made of rod-iron, bent into triangular shape.
The improvements consist, first, in forming the three sides of the whiiile-tree straight, in order to give it strength and rigidity; second, in giving increased thickness er body to the longest side of the whiiiletree, the
vbetter to enable it to sustain endwise pressure or force; third, in providing the attachingloops of the whiletree'with replaceable thimbles or eyes, to sustain the wear, and relieve the whiiile-tree of the same.
The drawing is a perspective ,view vot' a set of whille-trees, illustrating my invention.
A A A represent a whiiiie-tree, made by bending rod-ironso as to form a triangle having three straight sides, united by the loops d a a. The middle loop a is forv the attachment of the whiile-tree to a. plough or wagon directly, or to a double-tree, as shown, the'attachment being effected by means of a hook, clevis, bolt, or otherwise. In like manner, the end loops ad are for the attachment ot' the'traces.A B B B are lrings or thi'mbles of cast or wrought iron, or other material, having circumferential grooves in their periphcries. These thimbles are fixed within the loops a e a, so as to be tightly embraced thereby. They may be placed within vthe loops when the iron forming the whie-tree is hot, so that they shall be tightly clamped hyshrinkage. Said thimbles form eyes for the attaching-loops of the whiiile-tree, and serve, by sustaining the wearto increase they,
durability of the whiiiie-trce and enhance its value. They m'ay beareadily replaced when worn. The longest side A of the whilIe-treejs made -with increased thickness or body, to enable it to sustain great endwise force.
lThe side A may be enlarged throughout its entire length, or the enlargment may be greatest at the central portion, and diminish toward the ends, thus giving that side of the whiiie-tree a tapering form. This part A of the whiiile-tree has to endure the greatest crushing force-or strain, and the enlargement supplies the necessary strength and rigidity without unduly increasing the weight.
Having thus described myl invention, what I claim as new, and desire to secure by Letters Patent, isf- 1. The whiile-treeA A', formed 'of bent metal, with three straight sides, one of which is enlarged in -the centre, to sustain endwise pressure, as described.
2. In bent-metal Whiiiie-trees, the replaceable rings or thimbles B, substantially as and for the purposes set forth.
