Opinions

ARCHBALD, District Judge.*

In a suit between the same parties, just decided (120 Fed. 282), the patent of Calvin Jackson for a coil clasp belt fastener has been sustained. The present proceedings have to do with a machine for making and inserting such coils, patented by the same party September 20, 1892 (No. 482,965). As de[290] scribed by the inventor, the machine consists, in substance, of two or more peripherally grooved rollers, journaled in a frame made up of a fixed and a movable part, hinged together; the rollers being simultaneously rotated by means of intermeshing gears, and being so located with reference to each other and the frame in which they are set as to form an intermediate space, in which the coil is operated. There are one or two modified forms of this, but none that we need to notice. It is essential to the efficient working of the machine that the upper half of the frame should be capable of being lifted away from the lower, — this being necessary to regulate the size of the coils to be formed, to allow the fabric in which a coil is to be inserted to be laid in place, and to adjust the clamping plates to different thicknesses of material and sizes of coils, so that pressure may be brought at the same time upon both; and, in order to keep the rolls in gear while this is being done, an intermediate gear-wheel is provided, which is pivoted at the hinging point of the two frames. Different forms of the machine are shown in section in the following diagrams':

[291] To- form a coil, the end of the wire out of which it is to be made is given one or more turns around a proper-size mandrel placed between the rollers, and, being forced forward by their pressure and rotary motion, is made to coil its way in a spiral track between the successive grooves of the upper and lower rollers; these grooves being set a little in advance of each other, according to the pitch of the spiral desired. Where the coil is to be inserted into other material, such as a belt or bag, the upper frame is raised on the hinge, and the fabric laid in between clamping plates, which hold it in place, when the frame is lowered; and, the edge of the fabric being made to extend into the space between the rollers in which the coil revolves, the coil is forced through it by their motion. According to the suggestion of the inventor, the coil may be made and inserted at one and the same time, or the two operations may proceed separately. The defendants are manufacturing a machine for inserting wire coils (but not making them), made up of similarly placed and similarly operating rollers geared together; but they deny that they have infringed the plaintiff’s patent, and they further contend that it is void for want of novelty. The particular features of the patent which are drawn in controversy are embodied in the second claim, which is as follows:

“(2) In a wire-coil machine, substantially as described, the combination with one or more rollers supported in a fixed frame, of one or more similar rollers supported in a movable frame pivoted to the fixed frame, said rollers being geared with a gear-wheel, having its center at said pivotal point, substantially as set forth.”
