4 Claims, 8 Drawing Figures Germany 32/14- BOW FORMING PLIER CROSS-REFERENCE TO RELATED INVENTIONS The plier of this invention pertains in a related manner to a parallel jaw plier such as shown in US. Pat. No. 3,710,657 which is assigned to the assignee of this invention. This patent was issued on .Ian. 16, 1972 in the name of Anthony J. Cusato and assigned to Henry Mann, Inc.

BACKGROUND OF THE INVENTION noted above a parallel jaw plier is shown in U.S. Pat.

No. 3,710,657 as issued to Anthony J. Cusato on Jan. 16, I972. Pliers whose jaws are particularly configured to provide loops such as are used in orthodontics as far as is known are confined generally to round or needlenose pliers in which the wire is grasped and rolled around one of the jaws of the pliers.

SUMMARY OF THE INVENTION.

This invention may be summarized at least in part with reference to its objects.

It is an object of this invention to provide, and it does provide, a bow forming plier in which the jaws have mated grooves and offset configurations so constructed formed as members which are movable by the handles while there is no wire between the jaw portions. The jaws of the plier are used to form special offset portions and loops or bows in the wire.

In addition to the above summary the following disclosure is detailed to insure adequacy and aid in understanding of the invention. This disclosure, however, is not intended to prejudice that purpose of a patent which is to cover the inventive concept therein no matter how it may later be disguised by variations in form or additions of further improvements. For this reason there has been chosen a specific embodiment of the bow forming plier as adopted for use in forming loops, offsets and the like in wire particularly used by orthodontists. This specific embodiment has been chosen for the purposes of illustration and description as shown in the accompanying drawing wherein:

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 represents an isometric view of the bow forming plier of this invention with the jaws in an open condition whereat either the wire may be cut by the wire cutters or the wire to be acted on may be brought to the that precise loops and offsets may be formed in the wire.

It is a further object of this invention to provide, and it does provide, a parallel jaw plier in which there is a loop forming groove, a loop closing groove and a bend offset enabling a bend or stop to be formed.

This bow forming plier is a parallel jaw plier particularly useful for orthodontists. In addition to a wire cuttingmeans there isformed in hardened inserts in the jaw faces an offset permitting the wire to be bent into an offset or bayonet stop. Adjacent this offset portion is a loop forming groove which initially forms a partial loop and then is used to close the loop. An-adjacent loop forming groove is provided to shape, close and/or open loops.

In the present invention the bow forming plier is adapted for heavy duty forming of wire of several sizes and as such is provided with a jaw specially adapted to form loops or offsets in the wire of a determined nature and at a determined place. This configuration of the jaws as shown in the drawing permits the wire forming to be precisely controlled and where desired repeated within very close limits. In particular, the parallel jaw action of the plier permits the wire to be gripped in a precise manner and as the jaws are brought together there is no change in relative angles so that the wire when gripped in the jaw firmly retained in specially formed notches in the upper and lower jaws when the jaws are brought to the desired gripping condition is formed into the desired loop. The plier, to be hereinafter more fully described, has a cutting means formed exterior of the forming jaws. These cutting edges are jaws for forming or bending;

FIG. 2 represents an isometric view of the lower jaw of this plier assuming that this bow forming plier is positioned with the wire cutting jaws in the top or upper posotion. The lower, jaw includes a shelf with loop forming assists and at the forward or distal end is a narrow shelf used with'the upper jaw to form the loop;

FIG. 3 represents an isometric view of the upper' jaw which mates with the lower jaw, in this view it is assumed that the jaw has been rotated one hundredeighty degrees from the position of FIG. 1 for the purposes of illustration and description;

FIG. 4 represents a fragmentary sectional view showing the upper and lower jaws of the plier in the position of FIG. 1 with the jaws being brought together to initially start a bend mark on a wire inserted between the jaws;

FIG. 5 represents a sectional view of the jaws and wire of FIG. 4 when and as the jaws are brought together to form an off-set bend or stop;

FIG. 6 represents a sectional view of the distal end of the jaws showing a wire placed in groove portions formed in the upper and lower jaws and in cooperation with a mating groove portion formed in the upper jaw the wire is formed into a partial loop;

FIG. 7 represents a sectional view of the jaws with a partially formed loop of the wire placed in the loop holding grooves and prior to the jaws being closed, and

FIG. 8 represents a sectional view of the jaws and wire of FIG. 7 after the jaws are moved to cause the wire loop to be squeezed into its closed condition.

In the following description and in the claims various details will be identified by specific means for convenience; these names, however, are intended to be generic in their application. Corresponding reference characters. refer to like members throughout the several figures of the drawing.

The drawing accompanying, and forming part of, this specification discloses certain details of construction for the purpose of explanation but it should be understood that structural details may be modified in various respects without departure from the concept and principles of the invention.

DESCRIPTION OF THE BOW FORMING PLIER OF THIS INVENTION Referring now to the embodiment as seen in FIGS. 1 through 3 there is depicted a parallel jaw plier having handles 12 and 14 which are pivoted by and actuate pivots-l6, l7 and 18. The movement of these handles and the connected retaining means used with the rear portions of the normal parallel jaw configuration cause lower jaw member and upper jaw member 22 to be moved toward or away from each other in a conventional parallel movement manner.

On the upper jaw 22 is carried an upwardly extending cutting jaw member 24 having a cutting edge 25 which cooperates with a like cutting edge 26 formed on upwardly extending rear portion 28. Portion 28 is link member carried by pivots l6 and 17. Where the cutting edges 25 and 26 occur hardened inserts of tool steel or carbide are provided on member 24 and portion 28. This wire cutting means is conventionally known and is merely shown by a means of illustration and no patentability isascribed thereto. Wire cutting ability is desired in the bow forming pliers so as to cut the wire conveniently and the visibly exposed shear-type compression-type cutting means depicted is one means.

The lower jaw 20 is a hardened tool steel insert and has its working surface formed with a shelf portion 30. Also formed in .the lower jaw is an upwardly extending portion32 generally made as a square member which, as reduced to practice, is made approximately oneeighth inch wide and three thirty-seconds of an inch high. Near the front or outer end of this upward extending portion 32 is formed a groove 34 which is sized to removably retain the largest wire to be found with this bow plier. This groove 34 is semicircular and has a rounded bottom in which a wire may be nested without distorting or deforming the surface of the wire. This jaw shelf portion as it extends outwardly is reduced in width to form an extending tongue member which, as reduced to practice, is approximately one-eighth of an inch in width. This extending tongue member, identified as 36, has formed therein a shallow wire retaining groove 38 whichis best seen in FIG. 2. To the rear of Y the upwardly extending portion 32 and slightly above the shelf portion 30 is a planar portion 40 haing a knurled surface. This knurled surface in combination with. the upper jaw provides a support on and between which the wire may be straightened if it has been brought to an undesired bent configuration.

Referring next to FIG. 3 there is depicted the upper jaw rotated 180 for illustrative purposes. This upper jaw 22 is made so as to mate with the lower jaw 20 when the jaws are brought together. This upper jaw is also an insert of hardened metal such as tool steel. In the upper jaw which isopposite the shelf 30 of the lower jaw is formed a downwardly extending rectangular shelf member 50 which has a depth substantially identical to the depth of member 32 formed on the lower jaw. This member 50 may be slightly wider or substantially the same' width as the jaw 32. In this upper jaw member 50 and spaced so as to be positioned exactly in alignment with groove 34 when the jaws are brought together is'a sloped notch 52 for a purpose to be hereinafter later described. This notch has a semicircular configuration made at about to the flat surface of member 50. A planar surface 54 is formed on the jaw and is below shelf member 50. The forward end of this jaw is rounded to bring the forward portion of this jaw at end 56 to a width which is approximately the same width as the downwardly extending jaw portion 50. In this manner 50 and adjacent the end of 56 is formed a groove 58 which is also semicircular. This groove 58 is deeper than groove 38 but is complementarily aligned with it when the upper and lower jaws are brought together. In the back porton of this jaw 22 is formed a flat knurled surface 60 which cooperates with knurled surface 40 in the lower jaw for the gripping and flattening of wire when required.

a wire after it has been cut as between the cutting edges 25 and 26 of members 24 and 28, as seen in FIG.

' 4, may be placed between upper and lower jaws 20 and 22. Initially the wire is engaged by member 32 and member 50. Both members are approximately the same depth, however, they are displaced sideways from each other to prevent cutting or shearing. As seen in FIG. 5, when the jaw 22 is moved toward jaw 20 the wire 70 is bent to nearly a Z-shape. This offset in the wire is provided by the extending member 32 as it engages the wire between that member and planar surface 54 and the number 50 as it engages the wire and'presses it toward the shelf portion 30. The bent wire is then technically described as having a bayonet bend or stop.

Referring now to FIGS. 6, 7 and 8 it is to be noted that where a wire is to be bent or formed into a loop the grooves 38 and 58 as well as the notch 34 and the groove 52 are utilized. The wire end is gripped in grooves 38 and 58 and as viewed in FIG. 6 the closed plier is then rotated in a counterclockwise direction. The longer length of wire is thus brought around the rounded undersurface of extending tongue 36 to form the open loop seen in FIG. 7. This incomplete or open loop is then placed in groove 34 and with the other side of the in sloped notch 52 the loop is closed as in FIG. 8.

With the loop forming portions and grooves on the small ends of the plier wire groove engaging portions 58 and 38 may be used by the operator forming the loop to easily squeeze the loop to the desired config'ura- 7 tion. If the loop is closed totoo great an extent the thin portion 36 provides on the lower jaw may be slid into a loop to force or manipulate the loop to the desired open or shaped condition.

Terms such as left, right, up, down, bottom, top, front, back," in, out," clockwise, counterclockwise and the like are applicable to the specific embodiment shown and described in conjunction with the drawing. These terms are merely for the purposes of description and do not necessarily apply to the position in which the bow forming plier may be constructed or used.

While this particular embodiment has been shown and described it is to be understood the invention is not limited thereto and protection is sought to the broadest extent the prior art allows.
