VOL. III. JULY 15, 1914 NO. 6 A EDITORIAL CHAT HEALTH AND THE EMPLOYEE. HEALTHY worker is generally a happy worker-consequently an efficient worker. Health is the first essential for success in any calling-whether it be brain work or muscular work. There is an old Latin saying "Mens sana in corpore sano"-a sound mind in a sound body. It is a good motto for any one to tack up over his work-bench. If the body and mind are sound and healthy there is no limit to the possessor's capacity for successful endeavor. To maintain both mind and body in the best of condition, to keep the eye clear, the muscles ready for quick response, we need a certain amount of play. We all have within us a whole lot of the child's instinct to romp around-and it is a good, normal, healthy instinct, too. A brisk game of any sort, out in the open air, makes one feel like a young colt turned out to pasture. One wants to kick up his heels and gallop around. To give this instinct free play is to take the first mportant step toward securing that sturdy health of body and elasticity of mind without which we are but machines, capable of only a limited field of action. It is the duty of every man to guard his health as one of his priceless possessions. It is the foundation of his happiness, of his efficiency in the world's work. The DISSTON Athletic Association, of which you will read in this issue, is one of the many ways in which we carry to practical ends our belief in the principle of conserving our co-worker's health. ITS HISTORY AND MAKING PART FOURTEEN A FILE used for general machine shop work, but not very often called for is the Equaling File. This is made along the same lines as a Flat File and is Blunt in form, and the "cut" is usually Bastard, Second Cut, and Smooth Cut. The Pillar File, is a file much like the Hand Flat File in section, but narrower. Reference to the sections, or forms, of files in Part Eleven will explain the difference much more clearly than it could be written. While Tapered, the taper is very slight. It is used in machine shops on narrow work such as slotting, or cutting grooves for cotters, and keys or wedges. There are two other files made especially for this work, but for which there is not such a strong demand. These are the Slotting File, which is a Blunt File, but usually slightly bellied, that is, with a curvature which runs from the point to the tang, and the Taper Cotter File, a flat file which tapers to a point and is cut on the sides and edges. The Arch File is flat in form, but bellied on the edges, tapering at each end. It is used on work in machine shops where this curvature of the edges is desirable. The Warding File is a very thin file from four to fourteen inches in length, and is used in slotting work by both jewelers and machinists, but especially by locksmiths for putting the slots or ward notches in kevs. A sort of connecting link between single and double-cut files is the Planer Knife File. While it is sometimes made double-cut on both sides, in its regular form each side is half single-cut and half double-cut. This file is for sharpening planer knife blades while on the machine. This is a quicker and easier job than taking the blades out and grinding them. A file of somewhat peculiar form is the Oval Tumbler. This is used principally for die work. |
