  • PIVOT ARRANGEMENT [72] Inventor: Richard R. Wiss, Short Hills, NJ.
  • ABSTRACT Improved pivot arrangement in scissors, shears snips and the like tools, the tool having an internally threaded pivot bushing or tubular shaft located at the pivot point of the blades, the bushing having an enlarged head at one end and a reduced forward portion provided with two oppositely disposed flat sides.
  • a metal spring-type washer coated with a material having a low friction coefficient is disposed between one of the blades, through which the bushing projects, and the enlarged head of the bushing.
  • the other blade is provided with an opening with opposed flats accommodating the reduced portion of the bushing.
  • a locking screw having an enlarged head engages the internal threads of the bushing for adjusting the tightness between the blades; there being provided an antifriction washer between the locking screw head and the said other blade.
  • the invention relates to scissors, shears, snips and the like and particularly to an improved pivot arrangement for these tools.
  • Pivot arrangements in scissors, shears and the like cutting tools are generally known wherein a bushing or tubular shaft is provided with an inside thread and a locking screw fitting in this thread for tightening the blades of the scissors or shears together.
  • the invention consistsin such novel features, construction, arrangements, combination of parts and improvement as may be shown and described in connection with the device herein disclosed by way of example only and as illustrative of a preferred embodiment.
  • the basic concept of the invention is to reduce the friction between the rotating members of the tools and to improve the pivot arrangement of the prior art in such manner that the head of the locking screw rotates with the blade against which it abuts so thatthere is no relative motion between the head and the surface of the blade.
  • the head of the screw is enlarged and a washer with a low coefficient of friction is disposed under the 'head, specifically in such manner that the washer is not extruded from contact'by excessive transverse pressure, thus minimizing the friction when the screw is tightened and when an inevitablesmall motion of the anchored bushing in the blade takes place.
  • the head of the bushing is also enlarged for reducing the specific pressure between the head and the blade and for providing space for a spring washer which is coated with a material having a low coefficient of friction.
  • Another object of the invention is to provide a non-extrudable friction reducing member under the enlarged head of the bushing of the tool, which provides also a constant pressure force on the blades of the tool.
  • FIG. 1 shows typical shears embodying the pivot arrangement
  • FIG. 2 shows a thread snip with the pivot arrangement
  • FIG. 3 shows a section of the shears shown in FIG. 1, taken along lines 33,
  • FIG. 4 shows a section of the shears shown in FIG. 1, taken along lines 4-4, partly broken away;
  • FIG. 5 is a plan view of the upper blade of the shears viewed in the direction of arrow 5 in FIG. 3, partly broken away;
  • FIG. 6 is a side elevation of the pivot bushing
  • FIG. 7 is an axial view of the pivot bushing
  • FIG. 8 is the side elevation of the locking screw
  • FIG. 9 is the axial view of the locking screw
  • FIG. 10 is a section of the spring washer
  • FIG. 11 is an enlarged section of the spring washer, partly broken away, showing the friction reducing coating thereon;
  • FIG. 12 is a sectional view similar to FIG. 3, showing a variation of engaging elements of the pivot arrangement
  • FIG. 13 is a sectional view similar to FIG. 3, showing a further variation of engaging elements of the pivot arrangement
  • FIG. 14 is an exploded view of the elements seen in FIG. 12 or FIG. 13 in association with the blades, the latter being in section, and
  • FIG. 15 is a view similar to FIG. 5, showing a further variation of engaging elements of the pivot arrangement.
  • upper portion 25 provided with two oppositely disposed flat sides 26, 27.
  • the upper blade 28 (FIGS. 3 and 4) has an opening or hole 29 with oppositely disposed flats and into which forward portion 25 fits so that upper blade 28 and pivot bushing 24 will rotate together when the shears are operated.
  • Bushing 24 has a particularly enlarged head 30.
  • the lower blade 31 has a straight bore 32 into which bushing 24 fits rotatably.
  • Bore 32 may be recessed (counterbored or countersunk) for receiving head 30 and for the washer 33 which belongs to the class of metal spring-type washers such as the so-called Belleville springs.
  • Washer 33 is coated with a plastic material 33' which has a low friction coefficient and which can be cured on the spring metal at such a temperature as not to effect the temper of the metal. Examples of such materials may fall under the group of low temperature curing or baking resins, such as polyurethanes, epoxies and fluoro-carbons. An example of fluoro-carbons found most efficient is sold under the trademark Teflon S.
  • Bushing 24 has a threaded bore 34 into which locking screw 23 with screw head 22 engages tightly so that screw 23 is practically self-locking.
  • Screw 23 may comprise any type screw such as, for examples, Fillister head, oval head, hex head, slotted head, Phillips head or socket head cap screw.
  • a plastic insert 35 may be provided in screw 23, such as it is commercially available under the trademark Eslok," or ascrew with elastically deformable thread for example disclosed in U. S. Pat. No. 3,195,656, may be used.
  • Screw 23 has an enlarged head 22 which fits into the recess 36 (which may be a counter sink or counterbore) of blade 28.
  • a washer 37 consisting of a material having a low friction coefiicient is placed under head 22.
  • FIGS. 3 and 4 One assembly of the pivot is shown in FIGS. 3 and 4.
  • Upper blade 28 and lower blade 31 ar tightened together by locking screw 23 in bore 34 of bushing or tubular shaft 24.
  • Flattened portion 25 does not have to be fitted too tightly in slotted hole 29 which may be produced by a simple punching process.
  • washer 37 By placing washer 37 under enlarged head 22 of screw 23 the friction between upper surface of upper blade 28 and head 22 is considerably reduced so that the slight relative motion of shaft portion 25 of bushing 24 in slotted hole 29, caused by the tight fit of the former in the latter will not cause screw 22 to loosen up or to tighten itself involuntarily.
  • the novel pivot arrangement has basically screw 23 rotating together with upper blade 28 so that no relative motion exists between them.
  • the particularly enlarged head 30 of bushing 24 accounts for a lower specific pressure against lower blade 31, resulting in a smaller amount of friction, and spring washer 33 with the low friction material coated thereon placed under head 30 diminishes further the friction.
  • the result of this arrangement is two-fold; a larger total pressure can be applied to the blades for precise cutting of the shears, particularly in the case of trimmers, without rendering the shears too heavy to operate, and to maintain a constant pressure force on the engaging cutting edges of the blades of the shears. Both conditions contribute obviously to less wear of the moving parts over a long period of use ofthe shears.
  • the head 22 of screw 23 may be still further enlarged and accordingly recess 36 and antifriction washer 37 may be made larger to accommodate the further enlarged head.
  • FIG. 13 is a sectional view similar to FIG. 3, showing a variation of engaging elements of the pivot arrangement.
  • the angularity of conical or tapered spring washer 33A is designed to cause bearing pressure on the tapered portion 30A of bushing head 30A to be near the center of the bushing 24A.
  • the bearing pressure area is indicated in FIG. I2 by the character P.
  • the angularity of inverted conical or tapered spring washer 37A is designed to cause hearing pressure on the tapered portion 22A of conical head 22A of screw 23'.
  • the bearing pressure area is indicated on the screw head 22A at P.
  • FIG. 13 is a sectional view similar to FIG. 3, showing a further variation of engaging elements of the pivot arrangement.
  • the angularity of conical or tapered spring washer 33B is designed to cause bearing pressure on the tapered portion 30A of bushing head 30A.
  • the bearing pressure area is indicated in FIG. 13 by the character P.
  • the angularity of inserted conical or tapered spring washer 37B is designed to cause hearing pressure on the tapered portion 22A of conical head 22A" of screw 23'.
  • the bearing pressure area is indicated on the screw head 22A" at P'.
  • FIG. 14 is an exploded view of the elements seen in FIG. 12 or FIG. 13 in association with blades 28 and 31.
  • a nylon patch 38 or other suitable torque device is preferably provided on the locking screw 23'.
  • FIG. shows the use of a tapered head bushing combined with a flat head screw and an engaging flat anti-friction washer.
  • Flat head 22 of screw 23 engages flat anti-friction washer 37.
  • the angularity of conical or tapered spring washer 33A is designed to cause bearing pressure on the tapered portion 30A of bushing head 30A to be near the center of bushing 24A.
  • the bearing pressure area is indicated at P.
  • the angular disposition of the washers under the screw heads and under the bushing bodies is such that they still operate as a spring washer, so that dependent upon the angles chosen the pivot can be caused to operate near the periphery of the head, or near the body of the pivot itself, and in both cases still retain utilization of the spring principle.
