Abstract

110,998. Morser, H. Jan. 16, 1917. Wood-screws.-Screws for use in wood, metal, &c., have their shanks split and the legs B, B' separated so that they have to be pressed together before the screw can enter the hole. They thus tend to separate and maintain a firm grip notwithstanding shrinkage of the material and are also less likely to work loose when subject to vibration. Preferably they are made of harder materials than is usual so as to have more resilience.
