aw t w EOVSSBW HO .LNHWHSLLHHAGV INVENTOR VINCENT ANDERSON QEZQWMJKW ATTORNEYS WATCI-IBAND CALENDAR WITH JEWELRY-LIKE SURFACE This invention relates to processes for highlighting the indicia on watchband calendars, and more particularly to processes for providing high volume, low' cost watchband calendar production with maximum metal utilization.
Reference is made to a copending patent application (now U.S. Pat. No. 3,603,014) originally filed July 31, 1967, by Walter A. Schomburg, and assigned to the assignee of this application. That Schomburg patent shows a process for making a watchband calendar having a jewelry-like surface appearance. More particularly, a spin finish is applied to a thin metal sheet, before a calendar is printed thereon. The spin finish appears when the metal surface is abraded by rotating a resiliently ended, spinning device against the surface of the metal, while a grit material is positioned between the end of the device and the surface. For example, this could be a small circular disk of sandpaper, or the like; or, it could be a felt or rubber disk rubbing against a loose grit sprinkled over the surface of the metal.
The abrasion forms a plurality of generally concentric score lines with the center point of scoring substantially coinciding with the axis of the spinning shaft. The sheet of spin finished metal is then formed on a punch press, for example, into a central panel with the center point of the score lines positioned at approximately the center of the panel. At least one tab is integrally formed on said central panel and dimensioned to at least partially wrap around a wristwatch band. Next, a calendar is imprinted on the scored panel with the center of the calendar located at approximately the center point of the score lines. When the watch calendar is mounted on a wristwatch band, the normal wrist motion causes a variation in highlighting at different areas of the panel and calendar.
The Schomburg process makes a beautiful watchband calendar which has achieved a wide spread success with substantial commercial recognition. However, there is room for improvement of certain features of the Schomburg process. More particularly, the positioning of the spin finish tends to require a precision in production which enhances costs, rejection, and worker skills. Moreover, the spin finish tends to use an unduly large amount of material.
Accordingly, an object of the invention is to provide a new and improved process for applying a jewelry-like finish to watchband calendars. Here, an object is to provide for a continuous run production process which does not require an unnecessarily high degree of labor skill. Moreover, an object is to reduce the amount of metal required to make the watchband calendars.
Yet, another object of the invention is to provide a different type of jewelry-like finishes, as compared with the Schomburg type finish. Here, an object is to provide another in a family of surface finishes.
A further object is to provide a calendar, with a jewelry-like finish which can be manufactured and shipped in a compact manner, without requiring an undue amount of handling. Here, an object is to provide a year's (or a similar period) calendar supply in a single sheet, which may be mailed or otherwise sold or distributed as easily as a postcard, and without requiring either special handling or special packaging.
monthly calendars are printed over the score lines.
Thus, behind the calendars, the score lines provide a background of light reflecting areas which change as the watchband tilts and tips with normal wrist movement.
The nature of a preferred embodiment of the invention for accomplishing these and other objects of the invention may be understood best from a study of the attached drawing, wherein:
FIG. 1 is a graphical representation which shows the Schomburg method of scoring for enhancing a watchband calendar;
FIG. 2 is a graphical representation of the basic spin finish used in production of the watchband calendar of FIG. 1;
FIG. 3 is a graphical representation which shows a drag spin finish used in the inventive process;
FIG. 4 is a plan view which shows a sheet of calendars made by the inventive process; and
FIG. 5 shows a calendar for a single month, which has been snapped out of the sheet of FIG. 4 and is now ready to attach to a watchband.
The prior art, Schomburg process for making watchband calendars with a jewelry-like finish, is best seen in FIG. 1. Here, a sheet of aluminum 14 (or other suitable material) has a number of discrete spin finished areas formed thereon. For example, one such discrete spin finished area is formed at 15. This finished area is made by a rotating or spinning device held against the metal surface. The device has a resilient end with grit, or other abrasive material, positioned between the resilient end and the metal surface. It is not too important whether the grit is loose or is attached to a sheet of backing material. The concentric score lines are formed about a central point 16, coinciding with the shaft axis.
A plurality of such shafts may be aligned, side-byside, to raise and lower simultaneously. Thus, a plurality of such drag spun areas are simultaneously formed in multiple side-by-side relationship. By way of example, FIG. 1 shows an exemplary three such areas15, l7, and 18 formed side-by-side preferably in a single multiple, spinning operation. After the first multiple of three patterns, l5, l7, and 18 are so formed, the spinning shafts are raised. Then, the sheet 14 of metal is advanced by an indexed distance, and the three shafts are again lowered to form a new multiple of spun areas 19-21. In a similar manner, the shafts are repeatedly raised and lowered, with the metal sheet advanced each time to form a new spin finished area.
Thereafter, a calendar 22 for one month is printed on each of the spun areas. The calendar is centered upon the center of the score lines to enhance the overall appearances.
Then, the calendar is punched or stamped out of the sheet of metal in any suitable geometric form. For example, the stamped calendar 22 is in the form of a central panel 25, having two tab ends 26, 27 formed integrally therewith. The tab ends 26, 27 bend around a watchband to hold the calendar in place. In other modifications, the stamped out calendar may have any other suitable shape, such as an l-l-frame 28. The end product is made more handsome by the light reflective background.
There are three areas where the cost of this spin finished calendar may be made less costly. First, the three step cycle of raising the spinning shafts, indexing the metal sheet 14, and lowering the shafts requires above average production worker skill, time, and attention. Even with the higher skill levels, there is still a considerable chance for production errors and a resulting waste of end product. Second, there is a substantial waste of metal. Thus, the maximum width of the watchband sets the minimum diameter of the spin finish, which results in a greater waste than utilization of the metal. For example, spin design area 18 has been cross hatched to identify the wasted portion of metal required to produce a watchband calendar 29, for a single month. Third, the wasted material inherently requires the calendars to be completely separated from the sheet of metal 14, since the dimensions of a sheet required for a full years supply of calendars is too large to be practical. This separation into discrete calendars leads to separate packaging and much handling, so that a years supply of calendars may be assembled and sold as a unit.
In keeping with an aspect of the invention, these areas of cost have been reduced, while maintaining the jewelry-like finish and providing another in a family of products. In greater detail, FIG. 2 is a graphical representation of a spin finish, as applied in the manner taught by Schomburg. When a piece of metal having this finish is tipped and tilted, the reflected light rotates around the score lines 30 and appears somewhat as the blurred image ofa spinning propeller.
H0. 3 is a graphical representation of a drag spin. Here the rotating shaft is lowered onto and moved, in
I direction A, linerally across the metal to form nested score lines 31, which are spaced parallel portions of a somewhat semicircular or hyperbolic arc or a segment thereof. An exemplary three of the nested score lines are numbered 41, 42, 43. A linear drive table is preferably used to move the plate uniformily and without any discontinuing of motion, so that the lines will be uniformily spaced. When a plate having these nested score lines is tipped and tilted, bands of reflected light 32 and darkness 33 sweep longitudinally across the calendar face. The optical effect is somewhat similar to the optical effect in a tigers eye jewel stone. At the end of the drag spin finish, the circular spin finish 34 appears at the point where the spinning shaft breaks away from the surface, as it is lifted away.
A plurality of spinning shafts may be placed side-byside to create a plurality of drag spin patterns, as seen in FIG. 4. Here shown are three parallel strips of drag score lines 37, 38, 39, each having a number of nested score lines formed in spaced parallel semicircular or hyperbolic arcs (as seen at 41, 42, 43). Any suitable number of drag spin designs may be formed simultaneously.
The spun sheet is cleaned, and a full supply of discrete monthly calendars is printed thereon, with the printing centered on the score lines of the drag spin design, preferably so that the highest point of the hyperbolic arch is centered at the top of the calendar. However, the calendars may also be rotated with respect to the score lines, in some convenient amount, such as 90, for example. Here, for example, a January calendar is seen at 45. Other calendars may also be printed in any convenient groups, such as; 3, 6, 12, 15, or 18 month supplies. Thus, by way of example, a heavily inked rectangle 46 encloses 12 calendars, preferably printed in rows and columns, which is a years supply. The calendars may be printed as closely together as is practical, thereby minimizing wasted scrap metal between the calendars.
Next, the sheet of metal is coated with either a clear or gold and transparent lacquer to give a silver or gold surface appearance. For other effects, any suitable colored lacquer may also be used.
Then, the sheet of metal is placed under the die of a punch press or in a similar machine, and a semi-piercing die stamps out the entire perimeter around each of the calendars, except for one or more hinge areas. For example, a heavy inked line 47 is shown around the perimeter of the calendar 45 with two small broken segments at 48, 49. The heavy line 47 indicates where the calendar is cut, and the segments 48, 49 indicate where hinge portions are formed. The die which cuts along the line 47 may also be arranged to weaken the hinge segments 48, 49, to insure easy breakage. In a similar manner, the perimeter around each of-the other calendars is pierced, except for the small hinge portions.
The metal sheet 14 is also severed along line 46 at the same time. Hence, the large sheet of metal 14 is severed, as along line 46, into a number of small discrete sheets of metal, each of which is approximately the size of a postcard. Each small sheet contains a full supply of calendars which are cut out, and ready to be snapped out, as they are used. If a smaller supply of calendars are used, the perimeter 46 may be reduced to approximately the size of a business card carrying say three or four calendars. For larger supplies, the perimeter 46 may be increased.
Depending upon the customers needs, the cutout card 46 may also contain advertisement or any other messages at a tab end 51. As here shown, the tab end does not have a spin finish; however, it is also, within the scope of the invention to apply a spin finish this end. This tab end with a spin finish is particularly attractive when the end is in the form of a business card, which may be snapped off at 52 and kept.
The circular disk-like spin finished area 54, where the abrasive disks are lifted off the sheet 14 may be used as a background for a discrete calendar 55, constructed according to the Schomburgs teaching.
FIG. 5 shows a single, discrete, months calendar 45, which has been snapped out of the sheet 46. To use the calendar 45, the area is placed over and the tab ends 61, 62 are bent around the watchband.
Briefly, in resume, it is seen that the invention retains the jewelry-like appearance, maximizes metal usage and minimizes metal waste. A full years supply is small and compact, and may be as small as, say, a postcard,
thereby eliminating the need fol-separate packaging of discrete elements. It also enables advertising, business card, and similar display. The production costs less since the need for intermittent hand labor with accurate indexing is reduced. Still other advantages will readily occur to those who are skilled in the art.
The invention is subject to various modification. For example, the foregoing specification has spoken of sheets of metal such as aluminum (which may be 0.012 inch thick), for example. However, any other suitable metal, such as steel, bronze, or the like, may also be used. Moreover, the calendar may be rotated with respect to the score lines, as by 90, for example. Therefore, the appended claims are to be construed to cover all equivalent structures.
