JOHN D. JOHNSTON, OF NEWPORT, RI-IODE ISLAND.
SPECIFICATION forming part of Letters Patent No. 644,176, dated February 27, 1900, Application filed September 8, 1899. serial No. 729,831. (No model.)
To (LZZ whom it may concern-.-
Be it known that, I, J OHN D. JOHNSTON, a citizen of the United States, residing at Newport, in the county of Newport and State of Rhode Island, have invented certain new and useful Improvements in Wall-Ties; and I do declare the following to 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 novel improvement in wall-ties for building in brick and stone walls; and the object is to provide a simple, inexpensive, convenient, strong, and durable device of this character.
To this end my invention consists in the construction and arrangement of the wall-tie, as will be hereinafter more fully described, and particularly pointed out in the claim.
The figure in the drawing is a perspective view of my improved wall-tie.
My improved wall-tie consists of a sheetmetal plate of a thickness corresponding to the strength required, and it'comprises two counterpart integral sections 1 and 2, which are approximately V-shaped in plan and having the meeting apices of their acute angles connected by an integral longitudinal bridge 3.
The outer ends of the diverging sides 4 4, which form the meeting sections, are connected by the transverse integral parallel end braces 5 5, which are provided with the integral longitudinally-alined ears 6 6, and from these end braces 5 5 the alined central longitudinal integral braces 7 7 extend to the bridge 3 to secure the maximum strength when the tie is subjected to a longitudinal strain.
Lateral auxiliary ears 8 8 are formed integral with the diverging sides 4 4, and similar ears 6 6 are formed with the orifices 10 10 to receive nails or spikes to assist the tie in strengthening the wall. These ears may be turned at rig-ht angles to the plane of the tie and enter the joints in the wall between the bricks or may be nailed or screwed to the timbers when the walls are veneered with brick or stone.
In the accompanying drawingIhave shown my improved wall-tie in the best form now known to me; but various changes in the details may be made within the skill of a capable mechanic without departing from the spirit of my invention.
Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s
A wall-tie formed of a single piece of sheet metal and consisting of two V-shaped sections, having their apices connected by a longitudinal bridge and their diverging ends connected by transverse parallel braces formed with longitudinal orificed ears and the longitudinally-alined braces connecting said bridge and the transverse parallel braces, substantially as shown and described.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
JOHN D. JOHNSTON.
