Abstract

Wire binding is placed around hoses or packages or any other item requiring a binder by first forming a wire into a hairpin shape. The doubled wire is placed around the object and the ends are brought through the bight. The bight is engaged with the nose of a hand tool and the ends attached to a windlass which extends from the hand tool. Rotation of the windlass by operation of plier-like handles causes the wire to be wound upon the windlass, tightening the wire around the object. The tool is then rotated about the bight of the wire which brings the ends of the wire bent over from around the bight. The ends of the wire are snipped off, thus completing the binding.

2. Description of the Prior Art.

At the present time, there are automatic strapping machines commercially available. These strapping machines are large, expensive machines made for attaching straps or bands around packages. Also, most hoses are attached to nipples by hose clamps which generally include a threaded member, i.e., a nut and a bolt within a wire clamp.

SUMMARY OF THE INVENTION New and Different Function.

I have invented a hand operated wire binder which is specifically designed to tightly bind wire around an object. My small, simple, inexpensive hand tool permits workmen to quickly make hose clamps to fit whatever size hose is before them and, also, enables them to bind packages. It has almost complete versatility and may be used for hoses smaller than one inch in diameter or packages over 12 feet in circumference. Basically, the operation is: first, the wire to be bound around the object is doubled, forming something of a hairpin with a bight in the center. The doubled wire is a few inches longer than the circumference of the object to be bound. Then, the doubled wire is placed around the object to be bound and the ends brought through the loop or bight. At this point, my special hand tool is used with a notch of the tool engaged with the bight of the wire. Each of the ends of the wire is engaged with the ends of a miniature windlass in the form of a slotted shaft on the tool. Operation of plier-like handle operates a ratchet which causes rotation of the windlass, which draws up the ends of the wire and, therefore, tightening the wire. With the notch of the nose still engaged with the bight, the entire tool is rotated, bringing the ends of the wire back upon themselves, forming a loop around the bight. The ends of the wire are cut, thus forming the completed connection of the wire binding.

OBJECTS OF THIS INVENTION:

An object of this invention is to secure a wire binding around an object and to provide a hand tool for accomplishing this function.

Other objects are to achieve the above with a device that is sturdy, compact, durable, lightweight, simple, safe, efficient, versatile, and reliable, yet inexpensive and easy to manufacture, operate and maintain.

Further objects are to achieve the above with a method that is versatile, rapid, efficient, and inexpensive, and does not require skilled people to adjust, operate, and maintain.

The specific nature of the invention, as well as other objects, uses, and advantages thereof, will clearly appear from the following description and from the accompanying drawing, the different views of which are not necessarily to the same scale.

BRIEF DESCRIPTION OF THE DRAWING:

FIG. I is a perspective view of a tool according to this invention.

of a hose being bound thereby.

FIG. 5 is a top plan view of the tool in use.

FIG. 6 is a view of a part of the tool disassembled showing the ratchet handle with the ratchet and pawl therein.

DESCRIPTION OF THE PREFERRED EMBODIMENT This tool is particularly designed to be easily constructed of sheet metal parts stamped on a press. The principal parts include nose handle 10, ratchet handle 12, windlass 14, complete with ratchet wheel 16, pawl 18, pawl spring 20 and main spring 22.

The nose handle 10 is curved similar to the handles of a pair of pliers and is pivoted by the windlass 14 to the ratchet handle 12. Nose 24 is an integral portion of the nose handle 10 and extends opposite from the windlass 14 from the main handle portion 26. The nose includes notch 28 at the extreme end thereof so the notch in the nose 24 may engage bight 30 of wire 32. When so engaged, the windlass axis will be parallel to the bight.

The ratchet handle in the exterior includes only a handle itself and slot 34 through which extends reversing pin 36 of the pawl 18. On the interior, as more particularly seen in FIG. 1, there are two halves adapted to be held together by rivet 38. On the interior, FIG. 6,

it may be seen that the pawl 18 is engaged with the the ratchet wheel 16 and maintains it either in the for-.

ward position (shown in FIGS. 1, 3, and 4) or in the reverse position (shown in FIG. 6). The pawl and ratchet are well known mechanisms by which the ratchet wheel and thus the windlass are driven in a certain direction, that certain direction depending upon whether the pin 36 is in the forward position or the reverse position. The windlass 14 is prevented from going backward by the natural resilience of the wire 32 attached within the slots 40. Of course, the handles are returned to a spread position by the main spring 22. Therefore, it may be seen that if the wires are engaged in the slots 40 and the handles 10 andl2 are successively squeezed, the windlass is rotated, which will draw the wires 32 and wind the wires around the windlass 14.

To use the device, the wire 32 is bent double and the ends adjusted so the length of the doubled wire is a few inches longer than the circumference of the object 42 to be bound. The wire is looped around the object and the ends of the wire are brought through the bight 30. The hand tool is engaged with the notch 28 of the nose 24 engaged with the bight 30 and the ends of the wire engaged in the slots 40 of the windlass 14 (this position is illustrated in FIGS. 4 and 5). The operator successively squeezes the ratchet handle to the nose handle 10 with the reversing pin 36 of the pawl 18 in the up position causing the windlass 14 to be rotated; the wire 32 will be tightened around the object 42, the pressure being distributed between the bight 30 and the ends of the wire to pull the wire 32 tight.

As soon as the desired tension is exerted upon the wire 32, the squeezing of the handles and 12 together is ceased and the entire tool rotated about the bight of the wire as an axis. This, of course, will be the same as saying the entire tool is rotated around the notch 28 in the nose 24. The tool is rotated a full 180, and then the ends of the wire 32 are snipped off with conventional wire cutters adjacent to the bight. The tool is removed and the binding is complete (FIG. 2).

The embodiment shown and described above is only exemplary. I do not claim to have invented all the parts, elements or steps described. Various modifications can be made in the construction, material, arrangement, and operation, and still be within the scope of my invention. The limits of the invention and the bounds of the patent protection are measured by and defined in the following claims. The restrictive description and drawing of the specific example above do not point out what an infringement of this patent would be, but are to enable the reader to make and use the invention.
