Also “The combination of a needle and a shuttle, or equivalent, and holding surfaces, constructed and operating substantially as described.” Also “The combination of holding surfaces with a baster plate or equivalent, constructed and operating substantially as described.” Also “A grooved and eye-pointed needle, constructed and adapted for rapid machine sewing substantially as described.” When the machine commenced to be a practical success this patent was infringed, and when Howe sued upon it a few years after its issue, it woke up Hunt and all other alleged prior inventors; and all prior patents and publications the world over, relating to sewing machines, were raked up to defeat Howe’s claims. But the courts, after long deliberation, held that although, so far as Hunt was concerned he had without doubt made a machine in many respects like Howe’s machine, that it had a curved, eye-pointed needle similar to Howe’s operated by a vibrating arm and going through the cloth, a shuttle carrying the thread that passed through the loop made by the needle thread, thus making a lock stitch by drawing it up to one side of the cloth, and that this machine did, to a certain extent, sew, yet that it ended in an experiment, was laid aside, destroyed, and never perfected nor used so as to give to the public the knowledge and benefit of a completed invention, and was not therefore an anticipation in the eye of the law of Howe’s completed, more successful and patented machine. Public successful use is the fact in many cases which alone establishes the title of an inventor, when all other tests fail. And this is right in one sense, as the laws of all countries in respect to protection by patents for inventions are based upon the primary condition of benefit to society. This benefit is not derived from the inventor who hides his completed invention for years in his closet, or throws it on a dust heap. As to previous patents and publications, some were not published before Howe’s inventions were made, and others were insufficient in showing substantially the same machine and mode of operation. And as to prior use abroad, it was not regarded under the law of his country as competent evidence. Seldom have the lives of great inventors presented a more striking example of the vicissitudes, the despair, and the final triumphs of fortune, which are commonly their lot, than is shown in the case of Howe. A machinist with a wife and children to support, his health too feeble to earn hardly a scanty living, he watches his faithful wife ply her constant needle, and wonders why a machine cannot be made to do the work. The idea cannot be put aside, and with such poor aids as he can command he commences his task.
