TOP-PROP NUT.

SPECQLFICATION forming part of Letters Patent No. 4d3,799, dated December 30, 1890.

Application filed September 24, 1890- Serial No. 365,959. (No model.)

To all whom it may concern:

Be it known that I, ANSON SEARLS, a citizen of the United States, residing at Newark, county of Essex, State of New Jersey, have invented a new and useful Improvement in Top-Prop Nuts, of which the following is a specification.

My invention relates to top-prop nuts for carriages; and the objects are to provide a covering for the same and hold it firmly to the nut, also to give form to the covering with the head of the nut; and it consists in a threaded nut having a flanged head made in one piece,a covering made in one piece,having notches in the edge that remove the surplus material when turned inward, and a plate holding the under side of the covering between the flange of the nut and the plate, all as hereinafter more fully set forth.

In the drawings, Sheet 1, Figure 1 is a side view of a completed nut. Fig. 2 is a section through line at. Fig. 3 is a bottom view; and Fig. 4 is a view of the perforated plate 0, side and edge. Fig. 5 shows the covering B when made in one piece. Fig. 6, Sheet 2, shows the bottom of the nut with plate 0 and stitching S. Fig.7 is a section on line 2 2, showing disk D and top B made in two pieces; and Fig. 8

- is a blank form of top B.

The nut A, made of wrought or cast malleable iron, is provided with a threaded orifice g and a flange a, preferably rounded at the top to give shape to the covering B, and has a clinch c on the corner of the nut-square. A covering made of highly enameled or finished leather or like suitable material is cut to a proper diameter to cover the flange a on the top and turn under to the square of the nut. It is notched at its perimeter I), designed to turn under at the sides of the square, and b at the corners. These notches remove the excess of material from about the point (I when turned inward over the edge of the flange a. This blank B is set down into a cup-shaped recess about the diameter of the required finished nut that turns the edges 1) and I) upward. The nut A is then set therein, and with proper tools the edge is turned inward all around and down onto the flange a.

The plate 0, made of any desirable thickness of sheet metal, is centrally perforated to the size of the square of the nut A, and preferably of a diameter sufficient to cover the flange a, and is placed over the square of the nut A down upon the now inner edges of the covering B, holding the same between the flange a and plate 0, which is held in place by clinches 0, turned out of the nut A, preferably at the corners, down upon the plate C, where by the parts are securely fastened together.

It will be noticed that the covering flanges out a suitable distance from the flange a to admit of stitching S and a finished edge atB, Fig. 2. This edge outside of the stitching may be of the same finish as the top at B, dispensing with the turning, polishing, and blacking of the edges of leather-covered nuts as heretofore made. Where the enamel on the edge outside of the stitching may be cracked or injured in process of manufacture it may be polished off and blacked, as leather-covered nuts have been heretofore finished.

As a modification, in Fig. 7 I show the top B and bottom D of covering made in two pieces, using the same nut A and plate 0 and clinches c as when the covering is made in one piece. In this construction the diskD is first secured between the plate 0 and flange a by the clinch c and the top covering B joined thereto and stitched at S, and the edges also turned, polished, and blacked in the usual manner.

In using the covering B all in one piece I do not confine myself to the means described for holding the turn ed-in edge of the covering to the nut, as it is obvious that other means than the clinch 0 may be substituted without departing from my invention of a covering made in one piece flanged out from the nutand provided with the stitching S.

The nut A,with the flange a cast in one piece, rounded to give the proper shape to the covering B inside of the stitches S, has the threaded orifice g running entirely through to the covering, which sets out over the hole g in proper form, owing to being contracted at the stitching S, thereby dispensing with caps between the nut and the covering B, as heretofore used. A cap may be used over this oval head a; but I have not found it necessary in actual manufacture and use. By this means I produce a top-prop nut having the edge finished the same as the top at a reduced cost from the old mode of construction, and preserve a high and durable finish at the edge,

and hold the covering to the nut securely and neatly without any of the expensive rivets, plates, and clinches heretofore in use, and give form to the covering with a hole entirely through the nut, and make it deeper to screw upon the top-prop without punching the top olf and at a reduced saving in cost of the same from nut-s heretofore in use.

Having described my invention, What I claim as new, and desire to secure by Letters Patent, is-- 1. A nut provided with a covering made in one piece, having stitches and finished edge, as and for the purpose set forth.

2. A nut provided with a leather covering,

the inner edge of which is held between a plate 0 and flange a by clinches c, substan tially as and for the purpose sct'forth.

Nut A, having flanged top a cast thereto and rounded to give form to a covering, in combination with a covering B, plate 0, and clinch c, as set forth.

Signed on this the 23d day of September, 1890, at Newark, county of Essex, State of New Jersey.

ANSON SEARLS.
