ARTHUR M. WIGHT, OF NEW YORK, N. Y.

BANDING-TOOL.

Application filed January 5, 1912.

To all whom it may concern Be it known that I, ARTHUR M. WIGHT, citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and. useful Improvement in Banding- Tools, of which the following is a full, clear, concise, and exact description.

My invention relates to banding tools and its object is to provide a tool of simple construction in which the ends of a wire band can be quickly and easily secured to the cooperating jaws and in which said cooperating jaws may be easily opened apart to stretch the wire taut, and the tool then manipulated to twist the ends of the wire together.

The several features of my invention may be more readily understood by reference to the accompanying drawings, in which- Figure 1 is a side elevation of the preferred. embodiment of my invention, the tool being shown in position ready to begin the tightening of the wire about the box; Fig. 2 is a view similar to that of Fig. 1 of the opposite side of the tool; Fig. 3 is an end elevation of the tool shown in Figs. 1 and 2; Fig. 4 is a side elevation of a simplified form of tool embodying certain features of my invention, and Fig. 5 is an end elevation of the tool shown in Fig. 4.

Similar letters of reference refer to similar parts throughout the several views.

The two embodiments of my invention shown in Figs. 1, 2 and 3 and in Figs. 4 and 5, respectively, in general operate on the same principle, but in order to provide greater power I have introduced pawl and ratchet mechanism into the former in order to intensify the leverage and thereby to enable the operator to apply a wire of greater diameter to boxes carrying heavy loads. Since the tool shown in Figs. 4 and 5 embodies in simple form certain of the features shown in Figs. 1, 2 and 3, such simple form of tool will be described first.

Referring to Figs. 4 and 5, the tool consists of two levers 1 and 2 pivotally connected by a pin 3. The point of pivotal connection of the two levers is at the end of the lever 2, but is located between the handle of the lever 1 and the curved jaw 4 provided upon the inner end of the lever 1. The handle 2 is likewise provided with a curved jaw 5, said jaw, however, being carried by a downwardly extending post 6 pro- Specification of Letters Patent.

jecting from the lever 2 intermediate the ends of said lever. The jaw 5 is adapted to be supported. upon the surface of the box 7 which is being handed, and hence constitutes a supporting means for the tool. The jaw 5 ispreferably of segmental shape and is curved rearwardly toward the handle of the lever 2 and is provided at its rear or outer end with claws 8, between which is provided a notch for receiving the wire 9. Located immediately above the claws 8 is an end-retaining post 10 about which the end of the wire 9 is looped. The outer end of the jaw 4 is likewise provided with claws 11 between which is provided a notch 12 for recelving the opposite end of the wire 9. Upon one side of the jaw 4 are located two adjacent end-retaining posts 13, 14, about which the ends of the wire are adapted to be drawn to secure said wire to said jaw 4.

In operation the tool is placed upon its side on top of the boX 7 with the handle of the lever 2 extending toward the operator, and with the handle of the lever 1 pushed apart so that the heel 15 thereof will come in contact with the under surface of the lever 2. The end of the wire 9 is then provided with a loop which is placed about the post 10. The wire is then passed through the notch between the claws 8 around the curved surface of the jaw 5 and from thence around the box 7 in the direction indicated by the arrow, the opposite end of the wire passing around the boX, as indicated by the arrow, crossing itself approximately at the jaw 5, and is then brought underneath the jaw 4, through the notch 12 provided between the claws 11, and from thence about the posts 13 and 14, as shown in Fig. 4. While it is easy to form a loop in one end of the wire adapted to slip over the post 10 it would be comparatively diflicult to form a similar loop in the opposite end of the wire, whereas by carrying the wire around the posts 13 and 14, in the manner shown, that end of the wire is likewise securely held against slipping.

After the ends of the wire band are secured to the tool in the manner described, the operator grasps the handles of the two levers and turns the tool so that it rests upon its jaw 5. The lever 1 is then drawn toward the lever 2 until said lever 1 assumes substantially a vertical position, as shown in Fig. 4, in which position the wire band 9 has been drawn sufiiciently taut. While the tool is in this position the handle 2 is swung around to give a half turn or twist to the two ends of the wire to hold the same together under tension until said ends can be otherwise suitably secured together. After such twist or half turn is given to the ends of the wire and the tension thus taken from the two levers, the depression of the handle of the lever 2 will releasethe loop fromthe post 10, and the other end of the wire can then be readily released from the jaw 4. The ends of the wire are then clipped to suitable length.

It will be noted that in order to increase the leverage as the tension on the wire in creases, the curvature of the jaw 4 is such that the heel 15 thereof isnearer the pivot 3 than the outer end of said jaw. It follows, therefore, that during the operation of the lever to stretchthe wire the bearing of said wire upon the curved bottom of the jaw 4: gradually passes toward the heel 15, thus, as the strain increases, correspondingly increasing the leverage to the advantage of the operator- As has been stated thetool shown in Figs. 1, 2 and 3 has many features in common with the tool shown in Figs. land 5. Therefore for convenience, in the description of the preferred form of my invention, the parts corresponding to those already described in connection with Figs. 4 and 5 have been given the same reference numerals as heretofore but with a'distinguishing index letter.

Referring now to the preferred embodiment of my invention shown in Figs. '1, 2 and 3, the two levers 2 and 1 are pivotal'ly connected by a pin 3 As in the form hereinbefore described the lever 2 is provided with a curved jaw 5* carried by a downwardly extending post 6 projecting from the lever 2 intermediate the ends thereof. Said aw is provided with the post 10 and the'claws tl' 'corresponding in structure and functions to the post and claws hereinbefore described.

The aw 1 is in the form of a segment of a disk which is pivoted at itscenter, for which purpose it is provided with a stub axle 16 upon which said disk is keyed or otherwise secured. The stud axle 16 is .journaled in one end of a swinging arm 18.

Said arm 18 is pivoted at 29 upon the lever 2 intermediate the post 6 and the pivot pin 3 and is thus adapted to be swung upon its pivot 29 for purposes hereinafter to be described.

Opposite the segment 4? and integral therewith is a segment 17 having a toothed periphery which normally meshes with a pinion wheel 19. The pinion 19 is secured to the pivot pin 8* and likewise secured to said pin 3 is-a ratchet wheel .20. The lever 1 is provided with-a stepping pawl '21 pivoted thereto and arranged when the lever 1 is moved away from the lever 2 to engage and turn the ratchet wheel 20 in a well known manner. A retaining pawl 22 ipivoted upon the end of the lever 2 and is adapted to hold the ratchet wheel 20 in its operated position during the reverse stroke of the lever 1 Thus by manipulating the lever 1i back and forth and thereby turning the pinion wheel 19 the jaw 1 is caused to turn, thereby drawing the wire 9 taut.

In Fig. 1 the tool is shown in position ready to begin the tightening of the wire 9 about the box 7 in which position the heel 15 is in engagement with a stop 23 carried by the lever 2. By operating the handle 1 back and forth, as just described, the segment 4& is turned about its pivot 16 and the wire is thus drawn tight about the box. WVhen the wire band has been drawn sufii ciently taut, the lever 2 is swung around to give a half turn or twist to the two ends of the wire in the same manner as has been hereto-fore described. The ends of the wire are then released from the post 10 and the posts 13 and 14 It will be understood that the structure and function of the posts 13 and 1 1 the claws 11 and the notch 12 are similar to those hereinbefore described in connection with'the simpler type of tool. In order that the jaw 45 may be restored to its initial position shown in Fig. 1, said jaw is, as heretofore stated, pivoted upon a swinging arm 18. Said arm is normally held in the position shown in full lines in Fig. 2 by a catch 24 which engages with the upper surface of an extension 25 of the lever 18. The catch 24 is pivoted upon the lever 2 by a pin 26 and is normally held by a "leaf spring 27 in engagement with the pro theteeth of the segment 17 out of gear with the pinion wheel 19.

A coiled spring 28 thereupon acts to return the jaw 4* into engagement with the stop 23. Thereupon the lever 18 is depressed and the extension 25 thereof is reengaged by the catch 24, thus again bringing the teeth of the segment 17 into engagement with the pinion 19. The tool is thus restored to its normalor initial position.
