2 Claims.

This invention relates to harness wear loops and box loops and has as one of its objects to provide a wear loop and box loop that is an all purpose fixture and that is extremely flexible and positively secure.

Another object of the invention is to provide a wear loop and a box loop combined flexibly and that through its flexibility will not irritate the animal.

A further object of the invention is to provide harness wear loops and box loops combined that will protect the straps of harness.

A further object of the invention is to provide combined wear loops and box loops that readily lends itself to the use of scrap leather in its construction and that is therefore cheap to manufacture.

A further object of the invention is to provide combined. wear loops and box loops that is renew- 29 able and hence that will permit the re-use of the original hardwear also loweringthe cost to the consumer.

A further object of the invention is to provide a harness wear loop, consisting of a wear loop and a box loop, and arranging the wear loop to be secured in operable assembly by the strap it is intended to protect, and that will retain the box loop in fixed relation to the wear loop.

A further object of the invention is to provide a harness wear loop that is noiseless even though assembled with metal hardwear, and that will prevent sharp edges occurring on the hardwear from wear.

With these and other objects in view reference is now had to the accompanying drawing in which Fig. l is a side elevation of the device showing one form of its application;

Fig. 2 is a plan view of the device before form- Fig. 3 is a side elevation of a fragment of the flap and the securing hook;

Fig. 4 is a vertical section oi? the device showing the wear loop formed;

Fig. 5 is a similar view to Fig. l showing the wear loop in the position of the first step in opening; and

Fig. 6 is a similar view to Fig. 5 showing the wear loop opened and in a position to receive a connecting member.

Having reference to the drawing like numerals refer to like parts throughout the several views and the numeral 1 refers to the device as whole which is preferably constructed of leather or like material, and the device consists in general of a body member 2 adapted to be formed to provide a wear loop 3 and a box loop 4 from a single piece of material.

The body member 2, while preferably of a single piece of material, may be constructed of several pieces of what might otherwise be considered waste material and these formed into a single piece for the purpose in the usual well known manner, if deemed advisable, and also varying thickness of material can be used in either case the thickness being distributed to provide the wear loop portion where thegreater wear occurs.

The body member 2 is die or otherwise cut in the form of a T, the drawing shown in Fig; 2 showing the member inverted with reference to its T form, and the member consists of a base portion 5 representing the cross arm of, the T, a narrowing portion 6 extended upward from the base portion, the extended portion containing a recess 7 and being adapted to form a hinge strap connection between the base portion 5 and a tongue portion 8 extended from the narrowing portion and terminating in a securing end 9.

A flap 10 is preferably riveted to the securing end of the tongue to form therewith a securing hook 11, the flap being arranged therewith to turn abruptly back along the tongue to form the hook and to provide substantial rigidity therein.

The wear loop 3 and the box loop lare now produced by forming the body member 2 in the following manner:

As shown in Fig. 2 a rivet hole 12 is provided in each end of the base portion 5 when by bringing the two ends 13 of the base portion together with the two holes 12 in a registering position a rivet (not shown) may be inserted and secured in the usual manner to secure the ends together.

Obviously these ends may be secured in any other approved manner.

This operation will normally provide at this initial step a circular ring of the material and the ring is then flattened in the usual manner, 01' it may be preferably shaped to a rectangle by inserting a mandrel and pounding in the usual method of such well known operation, until the desired shape is produced, thus providing the commonly termed box loop 4.

To form the wear loop 3 the tongue 8 is curved to the general position shown in Fig. 6 and con-. tinuing the curvature the free end 14 of the flap 10 is inserted into recess 7 when the hook 11, formed by the flap 10 and tongue 3 as above mentioned, will join the end of the tongue with th narrowing portion 6 now forming the loop as shown in Fig. 5.

Before completion of the wear loop however a connecting member 15, which may be of the nature of a ring as shown, is placed over the securing end 9 to be brought down into the loop 3 to be removably secured there by the engagement of the hook with the recess 7 as above explained. At this stage the securing end is pressed downward toward the center of the box loop and the loop 3 raised in line with the box loop, the final position approximating the position centrally with the box loop, as shown in Figs. 4 and l.

The connecting member 15 and the wear loop 3 is now ready to receive a tension member 16 which is accomplished by inserting one end thereof into the free end 17 of the box loop 4, passing the strap (in this case) through the box loop, through the connecting member and around the wear loop to the position shown in Fig. 4, thence continuing the tension member back through the box loop to its proper destination.

The flap 10 preferably has the relative length shown in the respective drawings for the following purpose:

Theoretically there is no longitudinal strain on the device 1 the strain being communicated from the connecting member 15 pulling in one direction to the tension member 16 pulling in the other direction through the wear loop, the curved portion of the loop forming a bushing only between the opposing members.

Hence when a strain is applied at the wear loop end of the device that end is secured rigidly by the so formed bushing, interposed between the connecting and tension members, and being thus secured should some part of its own harness (not shown), or of a contiguous harness (also not ,shown), such as a snap catch or hook, or some other projection, catch into the box loop and pull against the secured wear loop it might be possible to forcibly disengage the securing hook 11 from the recess. 7

With the elongated flap 10 however the tension member 16 parallels adjacently both sides of the hook 11 and the full length of the flap 10, and the tension member being held to it's adjacent position by the box loop disengagement of the hook would be substantially impossible, therefore the strength of the hook would be at least equal to the strength of the material of which the device is composed.

The device being constructed of leather or like material is obviously universally flexible, i. c. it lends itself readily to flexure in any direction, and thus it is adapted to curve and seat properly about the connecting member 15, or against any part of a harnessed animal, providing for a noiseless union of the connecting and tension members and preventing chafing and undue irritation of the said animal.

In use, and where applied to a harness, the assembly will be as above described, and while a flat tension member 16 has been illustrated and referred to it is obvious that tension members of other cross section may be employed by shaping the box loop to correspond with or accommodate that member.

This application is filed in place of my abandoned application filed December 26, 1929, Serial No. 416,581.

Having thus described my invention I claim:

1. A combined wear loop and box loop, consisting of a flexible material, of T shape, the vertical stem providing a body and a securing flap adapted to form a wear loop intended to detachably encircle a connecting member, and the horizontal bar thereof being adapted to form a box loop, a recess provided in said body, a connecting means provided on the end of said stem, and adapted to engage the body through said recess to complete the wear loop, said box loop being adapted to receive a tension member for engagement with the wear loop and positioned to secure the fastening means in said recess.

2. A combined wear loop and box loop, consisting of a flexible material out to a general T shape, the vertical stem providing a body and a securing flap adapted to form a wear loop intended to removably encircle a connecting member, the horizontal bar thereof being adapted to form a box loop, said body containing a recess formed therein adjacent to the box loop in a manner to provide a hinge strap connection between said wear loop and said box loop, a securing hook formed on the end of the securing flap, for insertion in said recess to complete the wear loop, said box loop being positioned with respect to the recess to permit threading a tension member through the box loop and about the wear loop, and return through said box loop, in a manner to positively secure the connecting hook against accidental removal.

HOWARD V. HANSON.
