McLarty v. Jones Plastic Co., 175 F. Supp. 452, 123 U.S.P.Q. (BNA) 185, 1959 U.S. Dist. LEXIS 3239 (E.D. Mich. 1959).

Opinion

O’SULLIVAN, District Judge.

This is an action for infringement of a claimed patent, for injunctive relief and for damages and costs consequent upon the claimed infringement. Plaintiff Shirley McLarty was the patentee of Patent No. 2,797,510, and plaintiff National Banner Company has the exclusive sales rights to the device which is the subject matter of the patent. Defendant denies the validity of the patent in question, asserting that the claimed invention was anticipated by the prior art and by public use qf the components that make up the patented product, and deny infringement.

The subject matter of the patented article is described in the patent as an advertising spinner or fluttermill. It is a plastic device made up of two propellers and a center section to be strung on a cable, and designed to whirl in the wind as a means of attracting patronage at gas stations, used car lots and similar merchandising enterprises. It is made up in units of ten with varying bright colors, and the blades of each unit are so pitched as to cause the device to whirl when activated by the wind. The patentee, Shirley McLarty, is an engineer who has worked in plastics for some years. Plaintiff National Banner Company is a Dallas, Texas, concern marketing various advertising devices and had, previous to the putting together of the McLarty device, marketed various devices not unlike it, but which were crudely designed and were found to be less suitable and salable as an advertising medium. Interested in finding a better product, National Banner Company suggested to McLarty the creation of something of the general nature of the previous devices, but one that would be a better and more marketable one. In the year 1955, McLarty went to work to make the product that was ultimately patented. He perfected his device toward the end of 1955 and, through National Banner Company, commenced the sale thereof. The new device met with immediate success.

Application for the patent ultimately obtained was filed by McLarty on February 26,1956, and his patent was issued on July 2, 1957. The patent and its claims are described as follows:

“This invention relates to advertising media and more particularly to a wind actuated spinner adapted to be suspended, with like devices, on a cable adjacent a place of business to gain the attention of prospective patrons.
“It has long been the practice of persons dealing in certain types of merchandise, notably used automobiles, to create a carnival air about their premises by the ostentatious display of varicolored flags, pennants and other devices, usually strung on a cord or cable well above the ground to attract attention. These displays have become highly popular and some bladed, wind propelled devices for such use have been made in plastic and suspended on a cable as an attraction. However, it has been found that constant rotation of these devices on a cable, sometimes at high speed, soon wears out the bushing in the device through which the suspension cable passes.
“It is the object of this invention to provide a novel form of wind actuated advertising spinner.
[454]*454“Another object of the invention is to provide a bladed display device formed with a center section equipped with a bearing constituting a part of this invention and designed to resist wear on the center section of the device.
“Another object of the invention is to provide a bearing composed of axially aligned nylon bushings about which is molded the hub in the center section of the display device, the said bushings rotatably embracing a suspension cable and held against endwise displacement by like bushings of a different type of plastic material surrounding the cable, one contiguous with the outer end of each nylon bushing which latter, in turn, being restricted in its longitudinal displacement by a metal clip fastened to the cable on each side of the display device.
“Other objects will appear as the description proceeds when considered with the annexed drawing wherein:
“Fig. 1 is a perspective view of a display device and center bearing constructed according to the invention.
“Fig. 2 is a side elevational view.
“Fig. 3 is an exploded perspective view of the bearing assembly per se and
“Fig. 4 is a fragmentary view of the device on a larger scale showing the bearing assembly in longitudinal cross section.
“Continuing with a more detailed description of the drawing, reference numeral 10 denotes generally the advertising spinner which is of molded plastic, preferably polystyrene, to form a circular center section 11 and diametrical wings or blades 12 which are arranged at a proper angle to be deflected by wind to cause the device to turn on the suspension cable 13.
“The center section 11 is formed with a peripheral ring 14 and a plurality of progressively smaller concentric rings 15 and a series of radial ribs 16 (Fig. 1). These rings and ribs are both ornamental and functional in that they properly reinforce the center section to prevent warping or -distortion in extremely hot weather and consequently prolong the usefulness of the device.
“Each blade 12 has a peripheral rib 17 and a series of straight ribs 18 on each side thereof which extend from the center section 11 outwardly in divergent relationship toward the far edges of the blades 12. These ribs also are both ornamental and functional like the rings 15 and ribs 16 of the center section 11.
“The body of the device 10 is injection molded and in the process, a hub 19 is formed whose length is greater than the overall thickness of the center section. To produce the bearing in the hub 19, a nylon bushing 20 is set in the mold in which the spinner 10 is formed, one in each end of the cavity producing the hub 19, with their adjacent or inner ends in abutting relationship. The hot plastic flows about these bushings, and against the circular heads 21 of the latter and when the spinner is released from the mold the bushings 20 are firmly embedded in the hub 19.
“The cable 13 is passed through the bushings 20 in the manner shewn in Fig 4 and a pair of like bushings or sleeves 22 is threaded onto the cable, one on each side of the spinner 10 and each with its circular head 23 bearing against or in juxtaposition to the head 21 of an adjacent bushing 20. Adjacent the outer end of each bushing or sleeve 22 is a metal clip 24 of cylindrical shape which is pinched or dimpled onto the cable 13 to prevent its longitudinal displacement and to preclude like displacement of the spinner 10 itself.
“The spinners 10 are made preferably of different bright colored plastic and are spaced apart on the cable 13 which is strung between [455]*455suitable supports well above the ground. The wind strikes the blades 12 of the spinners 10, causing the latter to turn on the cable and attract the attention of passersby by their animation and coloring.
“The nylon bearing formed by the axially aligned bushings 20 and the associated elements in their particular relationship shown and described permits the spinner to rotate freely and for longer periods of time than if the polystyrene hub 19 were in direct contact with the cable 13.
