SHAFT-TUG GUARD.

EJPECIFICATION forming part of Letters Patent NO.34:1,075, dated May 4,1886.

Application liled Januaryll, 1886. Serial No. 159,246. (No model.)

To (LZZ whom it may concern:

Be it known that I, J. WENDEL TI-IEOBALD, a citizen of the United States, residing in N ewark, Essex county, New Jersey, have invented certain new and useful Improvements in Shaft- Tug Guards, fully described and represented in the following specification and the accompanying drawings, iorming a part of the same.

This invention consists in a removable metallic guard inserted within the shaft-tug to protect the same from the wear of the shaft, and in a novel means of fastening the girthbillet to such guard.

In the drawings, Figure 1 is a side view of the guard applied to a shaft-tug. Fig. 2 is a section of the same on line :0 :r in Fig. 1. Fig. 3 is a transyerse section of the guard alone; and Fig. 4: is a perspective view of the guard, showing a diilerent means of connecting the girth-billet thereto from that shown in Figs. 1, 2, and 3.

A is the shaft-tug. B is the buckle, by means of which the back billet is attached thereto.

a is the guard, which is provided with flanges a, projecting outward from the edges of the same, to hold it in position laterally within the tug. Y

b is a lining of leatherinserted upon the in nor face of the guard, and a are flanges projected inward from the edges of the guard to hold such lining in place. Such lining is not an essential part of the invention, but is inserted to protect the thills from wearing the guard.

c are lugs projecting from the guard, forming extensions of the flanges u, and connected by a bar, (I, said bar being shown in Figs. 1', 2, and 3, as formed integral with the lugs c, and in Fig. 4 as riveted thereto at its ends. In the construction shown in Figs. 1, 2, and 3 the girth is intended to be attached directly to the said bar, but in Fig. l a bar, g, is shown pivoted to the bar d by means of perforated lugs y thereon, and the same is provided with a billet-eye, f, thereon at the middle of its length. The snap-hook c, which is secured to the end of the girth, is inserted into the eyef when the girth is to be fastened to the guard.

In forming the bar (I integral with the lugs c, as shown in Figs. 1, 2, and 3, it will be seen that if the faces of the guard be made continucos it will be necessary to use a core in molding all the parts in one piece. In the construc tion shown I obviate this difficulty by making u a slot, 0, in the guard a, extending through the whole space between the lugs 0, through which the molding-sand projects from one part of the flask, thus making it necessary only to form the outer surface of the mold in the other part of the flask in order to form a complete mold without the core. By this means I avoid the expense which would be incurred in casting the guard without the slot 0, and by the use of a core.

It is evident that the slot 0 is not necessary in casting the guard shown in Fig. 4-, since the bar (Z is secured to the same after the casting is made.

I am aware of United States Patent No. 103,020, showing a casting similar to that described herein, scwed between the leather bands forming the tug, and I wholly disclaim the same, as it possesses entirely different functions from mine, in that it operates only to stiffen the tug, while the object of my invention is to form a means of protecting the tug from wear, as by the guard a, and the shaft itself by direct contact with the metallic guard, as by the lining I). XVhen the inner strap of the tug described in the above patent becomes worn out it is necessary to entirely reconstruct the tug around the casting; while the guard described herein, being removable, may be made and sold separate from the harness and be applied to any tug by the purchaser. Vhen the lining I) is worn out, it can without the slightest difficulty be taken out and a new one, formed from any piece of scrap leather, inserted without any sewing, thus making it easy for any one, although entirely unacquainted with harness-making, to remove the old lining and substitute a new one therefor. The above patent also shows lugs and a cross-bar as a means of connection to the girth similar to that shown in Figs. 1 and 2 of the annexed drawings, and I therefore disclaim such construction, limiting myself to the particular construction embodying the billet-eye pivoted to the lugs c.

lhe construction shown in Fig. 4: is intended for heavy harness, since it is evidently the more convenient of the two constructions shown, while the other construction, since it flanges a" and a and the lining b, as and. for

the purpose set forth.

presents a neater appearance, would be more suitable for light harness. I

It is obvious that the flange at, projecting inward from the inner face of the guard, may be omitted, thus allowing the shaft to rest upon and in immediate contact with the inner lace of the guard. l

Having thus set forth the nature of my invention, I claim the same in the following manner:

1. The combination, with the shaft-tug, of a removable guard fitted within the same and provided with an attachment for the girth, all constructed substantially as set forth.

2, The combination, with the shaft-tug, of the removable guard (1, provided with the J. WENDEL THEOBALD.
