BTBAW BEWINa MACHINE CO. V. EAMES. 189 �however, set as before, so as not to pierce at ail unless sprung over by the needle-guide. In the specification of No. 7,98 5 the featore of the setting of the needle so as not to pierce at ail unless sprang over by the needle-guide, and the necessity of the springing of the needle over by the needle-guide at every stroke, is omitted as an existing feature where the needle does not vibrate laterally, and is retained as a feature only wheu the needle vibrates laterally. In the original specification it was a necessary feature both when the needle did not vibrate laterally and when it did. The defendant's machine has no lateral vibration of the needle, nor any corresponding vibrating movement of the needle-guide. Nor, in the defendant's machine, is the needle set so as not to pierce unless sprung over by a needie-guide, nor is there a needle-guide which springs the needle over towards the bending device when the needle-point enters the guide. The specification of No. 7,985 is altered so as, when no vibration of the needle is employed, to make the operation of the needle-guide an operation merely to pre- vent the glancing of the needle-point frora the bent surface of the braid. ' Yet the needle-guide in Bosworth's original spec- ification had an operation to prevent the glancing of the needle-point from the bent surface of the braid, although it had an additional operation to spring the needle over so as to pierce the braid. In the defendant's machine there is an arrangement which operates as a needle-guide, so far as to prevent the glancing of the needle-point from the bent sur- face of the braid. In the original specification of Bosworth the feature of the needle-guide as preventing this glancing is set forth. That specification, when it speaks of "the spring- ing of the needle," means the springing of the needle by the glancing of its point from the bent surface of the braid, — a springing which must ensue if not counteracted by the inter- position of a bearing surface to resist. The apparatus de- scribed, to spring the needle over as it descends, necessarily involves the existence of the bearing surface to resist any tendency of the needle to glance off. The bearing surface to spring the needle over is the bearing surface to resist any ��� �
