TRACE-'EUG'.

Specification of Letters Patent.

Patented Got. 18, 1910.

Application filed September 10, 1909. Serial No. 517,054.

To all whom 'it may concern.'

Be it known thatJ l, Trroiuas M. BRADY, a citizen of the United States, residing at Clifton Forge, in the county of Alleghany and State of Virginia, have invented certain new 'and useful Improvements in Trace- Tugs, of which the following is a specification.

My invention relates to trace tugs, and the main object in mind was the production of an improved tug wherein all the parts which might in use be subjected to tension strains should be of metal; and wherein effective means should be provided for holding the box loop in proper1 position, part of said means to consist of an ornamental plate.

A further object was the production of such a tug which could easily be repaired when necessary.

lVith these ends in view, my invention consists in certain novelties of construction and combinations of parts as hereinafter set forth and claimed.

rllhe accompanying drawings illustrate two examples of the physical embodiment of the invention constructed according to the best modes of procedure I have so far devised for the purpose.

Figures 1 to 4 show the first example; Fig. 1 being a top plan view, Fig. '2 a longitudinal section, Fig. 3 a View of the metallic draft means as a whole, and Fig. 4 a cross section of Fig. 1 through the loop and parts below the same. Figs. 5 to 7 show the second example; Fig. 5 being a longitudinal section, Fig. 6 a view of the metallic draft means, and Fig. 7 a cross section of the en tire tug.

Referring to the first example, the numeral 1 designates a leather or other suitable base piece made of two thicknesses of material stitched along the side edges and one end to form a pocket, the other end being open; 2, two holes through the base piece; 3, the metallic draft bar comprising two shanks 4 and 5 perforated at their free ends, the shank 4 having an integral eye 6 and a short end 7 extending from the eye, and said end 7 and the shank adjacent the eye being perforated, and the shank 5 at one end perforated and lapped over the short end 7 of the other shank, all as shown; 8, a perforated metallic plate concavo-convex at one end and cut away at 9, 9 to form a relatively narrow opposite end 10, said plate preferably being of brass or other metal capable of receiving a high degree of polish; 11, a metallic U-shaped chape or clip having perforated free ends, one longer than the other, and a slot 12 at the other end for the tongue of a trace buckle; 13, the trace buckle of a well known construction; 14, a rivet by which the narrow end of plate 8 is rigidly secured to the shank 5 of the draft bar; 15, a box loop; and 1G, 17, two rivets. The shank 4 is inserted within the pocket of the base piece 1, the box loop slipped over the shank 5 until it bears against the body of the plate S atthe points 9, 9, the buckle inserted within the chape, the ends of the chape passed over the end of the shank 5, so that the longer end of the chape enters the loop and the shorter end bears against the edge thereof, and then the rivets 16 and 17 are passed through the alined holes at the ends of the shanks and chape, and also through the base, and the rivets upset, whereby all the parts are firmly and securely united.

Referring to Figs. 5, G and 7, the second example, the base 1S is preferably of a single piece of suitable material without a pocket; 19, the relatively long shank; and 20 the short shank located at the under surface of the base, both shanks being perforated, as shown. The remaining parts are like those of the first example and the parts are united by the rivets 21 and 22 substantially as hereinbefore described, as will be obvious from an inspection of the figures.

The shank 5 of the first example and shank 19 of the second example are each of the same width as the width of the opening through the box loop vwhereby the loop is firmly held to the base so it cannot turn when engaged by the shafts, an important feature of construction. The loop at the ends abuts the lower member of the chape and the extended edges of the plate 8 at the points 9, 9, so the loop cannot move longitudinally. The concavo-convex plate has its edges well overlapping the sides of the end of the tug adjacent the eye and, being of metal, it will withstand the frictional engagement of a shaft without being injured, as is common when leather is used between the eye and the loop. Should the buckle become broken, the rivet may be removed, the chape withdrawn and another buckle substituted without removing the shank or shanks. The tension strains are all taken by metallic parts and not by leather or other relatively weak material such as is commonly employed.

Obviously, I have produced an improved trace tug wherein the ends speciiied as the purpose of my invention are attained.

that I claim is:

l. A trace tug comprising a base piece; a box loop located in contact with the base piece; a metallic eye; a perforated metallic shank extending from the eye through the loop and ending adjacent the buckle; a separate, detachable U-shaped perforated and slotted chape passed over the end of the shank and one end extended into the loop; a buckle connected with the chape; and rivets passed through the several parts adjacent the ends of the tug; the shank being of the width of the opening through the loop whereby the loop will be held firmly in posi tion.

2. A trace tug comprising a base piece; a box loop located in contact with the base piece; a metallic eye; a perforated metallic shank extending from the eye through the loop; a U-shaped perforated and slotted chape passed over the end of the shank; a buckle connected with the chape; a cover plate located exterior of the shank and cut away at 9, 9 to form an end which is located within the loop and riveted to the shank; and rivets passed through the several parts adjacent the ends of the tug; one end of the chape abutting' the lower part of the loop whereby the same is held against longitudinal movement.

3. The combination with a trace tug having a leather base piece; an eye at one end, a buckle at the other end, a box loop intermediate the ends, and a metallic shank, of a separate detachable concave-convex cover plate with one end located within the loop, riveted to the shank; and of the same width as the base piece.

4. The combination in a trace tug, of a base piece; metallic draft means comprising an eye, a shank, a chape, and a buckle; a

box loop; and a cover plate; and rivets which pass through and firmly secure theJ parts in their relative positions; said cover plate being of the same width as the base piece and having one end located within the loop and riveted to a shank.

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