Definitions

  • ABSTRACT A mar-proof watch-band 1s made of materials havmg a 5 References Cited hardness greater than Hv 1,000. Suitable materials are UNITED STATES PATENTS hard nitrides, oxides and carbides, in combination with metallic binders.
  • Such materials may be ground 1,830,188 11/1931 Bellassemble 59/80 2,285,870 6/1942 Parker 74 255 to a mlrror'fimsh' 2,293,029 8/1942 Focke 74/255 9 Claims, 6 Drawing Figures HARD METAL WATCH BAND BACKGROUND OF THE INVENTION
  • Watch-bands having a useful life exceeding that of leather have generally been made of stainless steel or silver or gold alloys.
  • Such materials are nevertheless subject to scratching and abrasion by concrete, dust and the like so that it is difficult, if not impossible, to maintain such watch-bands in a condition in which they have a high lustre.
  • a watch-band in accordance with the present invention, is made of a hard nitride, a hard oxide or a hard carbide, where the material, in powdered form, is bound together by a suitable metallic binder.
  • Such materials when properly prepared, can be polished to a mirror finish which is essentially mar-proof due to the fact that select materials of this type have hardnesses in excess of Hv 1,000. Flexibility of such a watch-band is obtained by making the watch-band of individual links each of which has a tongue at one end and a groove at the other end, each link being held to the adjacent link by one or more pins passed through a cylindrical cavity in the walls of one groove and an aligned cylindrical cavity in the tongue of the adjacent link.
  • an object of the present invention is to provide an improved watch-band of high hardness.
  • Another object of the present invention is to provide an improved watch-band which can be finished to a mirror-like appearance.
  • a further object of the present invention is to provide an improved watch-band of a powdered nitride, carbide or oxide bound together with a metallic binder.
  • An important object of the present invention is to provide an improved watch-band which is essentially non-metallic in character.
  • a significant object of the present invention is to provide an improved watch-band having non-metallic links having a tongue at one end and a groove at the opposite end, said links being held together by pins passing through the sidewalls of said grooves and through said tongue.
  • compositions and an article of manufacture consisting of said compositions possessing the features, properties, and the relation of elements which will be exemplified in the article and compositions hereinafter described, and the scope of the invention will be indicated in the claims.
  • FIG. 2 is a plan view in partial section showing a mode of joining two adjacent links in said watch-band;
  • FIG. 3 is a side view in section showing how relative rotation between links is provided for
  • FIG. 4 is a side view in section of two adjacent links in a second embodiment
  • FIG. 5 is a sectional side view of a third embodiment of said links.
  • FIG. 6 is a plan view in partial section of two adjacent links wherein a single pin fastens each pair of links together rotatably.
  • compositions suitable for the manufacture of watchband links therefrom, where the watch links can be ground and polished to a mirror finish are as follows:
  • EXAMPLE I All quantities are in parts by weight EXAMPLE 2 TaC 3 EXAMPLE 3 WC 78 no 6 EXAMPLE 4 TaC 5 TIC 3 EXAMPLE 5 EXAMPLE 6 TiN 70 EXAMPLE 7 Si N 6O Ni 20 To-prepare watch-band links from any of the above compositions, the components of the composition, in powdered form, are placed in a ball mill having extra hard balls therein as well as a quantity of liquid such as benzene and the ball mill is rotated for about 24 hours.
  • the molded piece is in the form of a sheet having a tongue at one end and a groove at the opposite end as shown in FIG. 1, wherein a link 1 has a groove therein leaving sidewalls 1a and also has a tongue lb fitting between the sidewalls la with clearance.
  • FIG. 2 shows how adjacent links may be joined.
  • Sidewall la has a cylindrical cavity therein in which is placed a plastic bushing 2.
  • Tongue 1b of the adjacent link has a cylindrical cavity therein in which is placed the bushing 3.
  • the cavity in the sidewall la of the left hand link and the cavity in the tongue lb of the right hand link of FIG. 2 are aligned so that a single pin 4 can be inserted into both cavities.
  • pin 4 is stepped to form an interference fit with bushing 2 and a clearance fit with bushing 3. This construction provides for rotation of the links relative to each other around the axis of pin 4.
  • the other sidewall la of the left hand link is similarly joined by a second pin (not shown) at the bottom of the tongue lb.
  • rotation could also be achieved while holding the pin firmly in place by having an. interference fit between pin 4 and bushing 3 and a clearance fit between pin 4 and bushing 2.
  • the cavities in the sidewalls and tongue may be formed during the molding operation using an insert which burns away during the sintering operation, or may be bored into the links using a diamond drill.
  • a single cylindrical cavity passes through the entire length of the tongue lb.
  • This cylindrical cavity has a bushing therein and a pin 11, which, in the embodiment shown provides an interference fit with the pin 11.
  • clearance is shown between the surface 6 of a groove and the surface 5 ofa tongue.
  • the clearance needed is minimal in a construction shown in sectional side view in FIG. 3, where the right-hand link has a surface 5 which is a half cylinder. Slightly more clearance is needed where a corner such as 7 (FIG. 4) is present at the end of the right-hand link. In this case clearance is measured between the left-hand link and the circle 8 passing through the corners of the right-hand link.
  • rotation is limited by the fact that corner 9 can interfere with the bottom of the groove of the adjacent link. Such intereference is undesirable because the wedging action resulting in such a construction can result in fracture of the material of which the watch-band link is made or shearing ofthepin4.
  • the materials comprisingthe'watch-band links in accordance with the present invention have a hardness greater than 100 Hv, and consequently can be ground and polished economically only with a diamond wheel.
  • a mirror finish can be achieved which matches changes may be made in the above composition and the above article without departing from the spirit and scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
  • a mar-proof watch-band comprising a plurality of links of a material having a hardness of at least I-Iv 1,000, each of said links having a groove at one end thereof and a tongue at the opposite end thereof, each tongue being of such size that it fits with clearance within the groove of an adjacent link, each of said tongues having at least one cylindrical cavity therein, each of the sidewalls of each of each of said grooves having a cylindrical cavity therethrough, a plastic bushing in each of said cavities, the cavities and bushings in the groove sidewalls of one link being aligned with said cavity and bushing in the tongue of an adjacent link, and at least one. pin seated in said aligned bushings, said pin having an interference fit with one of said bushings and being received with clearance in an adjacent bushing.
  • a watch-band as defined in claim 2 wherein said hard oxide is A1 0 6.
  • each of said links has a mirror finish.
  • each tongue has a single cylindrical cavity passing completely therethrough, the wall cavities and the tongue cavity of a pair of adjacent links being aligned whereby a single pin may be passed through said wall cavities and said tongue cavity each having a plastic bushing therein, to hold said adjacent links together and provide for relative rotation with respect to each other, said pin having an interference lit with one of said tongue bushing or said groovewall bushings and a clearance fit with the other.
