SPECIFICATION forming part of Letters Patent No. 512,763, dated January 16, 1894.
Application filed May 18, 1893. Serial No. 474.722. (No model.)
To all whom it may concern.-
Be it known that I, THOMAS A. TAYLOR, a citizen of the United States, residing at Kenton, in the county of Hardin and State of Ohio, have invented a new and useful Improvement in J ail Grate Construction, of which thefollowing is a specication.
My invention relates to a form and method of making grating for jails, in which one series of fiat bars is passed through another series of iiat bars at right angles, and is secured at each intersection by a lug on one bar itting into a hole in the other bar and secured in place by a wedge which is riveted securely in position.
My invention is illustrated in the accompanying drawings, in which- Figure 1 is a face view of the vertical bar, and a sectional view of the horizontal bar. Fig. 2 is a sectional view of both the horizontal and vertical bars at the point of intersection. Fig. 3 isaperspective view of the wedge used in keying the bars together. Fig. 4 is a perspective view of the intersecting bars at point of intersection. Fig. isa face view of the vertical bar showing lug for lockinginto the horizontal bar. Fig. 6 is a face view of the horizontal bar showing hole into which the lug of the vertical bar'ts. Fig. 7 is a cross section of the vertical bar through the opening through whichvthe horizontal bar passes. Fig. 8 is a section of grating shown in elevation.
The vertical bars a have the slots a cut in them at any desirable interval for the reception of the horizontal bars b. From one side of the slot a there is a projecting lug d of size and form to closely fit into the hole b in the bars b; the other side of the slot ct is cut with the beveled surfaces a, as shown in Fig. 7. The space between the end of the lug d and the opposite surface c of the slot a is of sufficient width to admit the full thickness of the bar b. After the bar b has been set to its position with the lug d inserted into the hole b', the key c is set into the slot a filling the space between the bar b and the surfacec', and is driven tightly in until the beveled surface e of its head bears upon the surface a. The keyc is then held in position with a setting block beneath its head and its edge on the opposite side of the bar ct, is riveted down flush forming a head on that side which filling the countersunk surface a, prevents the key from being removed. Y This arrangement aiords a very sehaving the two heads when set with beveled.
