JACOB WVALIER OROWV, OF ARKADELPHIA, ARKANSAS, ASSIGNOR OF ONE- HALF TO AUSTIN M. OROWV, OF SAME PLACE.

STRINGER AND TIE FASTENER.

SPECIFICATION forming part of Letters Patent No. 353,624, dated November 30, 1886.

Application filed March 522, 1886. Serial No. 196,113.

TO'aZZ whom it may concern:

Be it known that I, J A0013 \VALTER CROW, a citizen of the United States, residing at Arkadelphia, in the county of Clarkand State of Arkansas, have invented certain new and useful Improvements in Stringer and Tie Fasteners; 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 In art to which it appcrtains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part. of this specification.

Hy invention has relation to stringer and tie fasteners; and it consists in the device hereinafter fully described and set forth.

I11 the accompanying drawings, Figures 1,

2, 3, and 6 are views showing the various shapes in which I may first cut the metal used in making my invention. Fig. 4 is a perspective view of my completed fastener. Fig. 5 is a longitudinal sectional view of a trestle work, showing a number of my fasteners in 'position.

My invention is described as follows: The stringer and tie fastener 1 may be cut out of any desired thickness of metal, and of any size or shape conformable to the conditions necessary to the properperformauce of the duties required of it and to the material upon which used, as hereinafter set forth. The plates 2, 3, I, and 5, after having been cut in the desired shape, have two of the diagonal corners, 6, bent down at right angles to the face of said plate and parallel to each other, and the remaining two diagonal corners, 7, are turned up at right angles to the face of said plate, and parallel with each other, and at right angles with the points 6, thus making a complete fastener, 1, as shown in Fig. 4.. The form of the plate, as shown in Fig. 6, is square, a segment being cutout of each side, as indi cated by the dotted lines a. The points 6 and 7 are then turned down and up, being bent on the doubledotted lines b. In bending the corners (3 and 7 to their respective angles I bend them on such lines that the corners 6,

(No model.)

which are turned down, may be somewhat longer than the corners 7, which turn up, to enable the builder or repairer to dislodge or draw out the upper points, 7, of the plate 1, from the under side of the timber without drawing or loosening the points 6 from the lower timber.

These tie-fasteners are designed to take the place of the old drift-bolt and linespike, and are used as follows: Place upon the stringer 8 one or more of the fasteners, with their long points 6 turned down and running with the grain of the w0od,drivethe same home until the under side of the plate rests against the face of the stringer, and then upon the two points 7,which point upward, place a tie, 9, and drive the same home. The two points 7, running 6 exactly opposite to the two long points 6 will also run with the grain of said tie, and hold the same as cfl'ectually and securely asif bolted in place. The stringer 8 is fastened to the abutment in the same manner.

The points of said fastener fitting closely in the grain of the wood prevents water from getting in and rusting said points, and the plate of said fastener prevents the timbers from fitting closely down, face to face, but causes a small space to be left between them, which allows of a free circulation of air, and thereby prevents the timbers rot-ting.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, 1s

A stringer and tie fastener, 1, being made of a plate of metal, as above described, having the shorter points, 7, turned up and perpendicular to the face of the plate and parallel with each other,and its longer points,6, turned down perpendicular to the face of said plate and parallel with each other, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
