HARRY G. NORWOOD nuts, usually caused by the excessive jarring that emanates from the rolling stock passing;

over the joints, will be prevented, and thebolts will be maintained in their proper transc verse alinementi It w l also be evident that-in the event that splice bar should be accidentall broken, this type of locking device possessr-o ing unusual strength will readily serve to c retain the railsin proper alinement untilithe' break is discovered and repaired, thereby preventing. what is known as lippingf of": the; track rails which; is liable to cause a "derailment of-therolli'ng stock;-
