Book excerpt: Excerpt from Screw Thread Cutting The terms pitch and lead of screw threads are often confused, and particularly in the case of multiple-threaded screws does this confusion cause difficulties. Before we therefore enter upon the subject of calculating change gears for the lathe for cutting screw threads, it may be well to make clear the real meaning of the words "pitch" and "lead" and their relation to the number of threads per inch. The pitch of a screw thread is the distance from the top of one thread to the top of the next, as shown in Fig. 1. No matter whether the screw has single, double, triple, or quadruple thread, tho pitch is always the distance from the top of one thread to the top of the next. Often, though improperly, the word "pitch" is used In the shop to denote "number of threads per inch." We hear of screws having 12 pitch thread, 16 pitch thread, etc. This is not correct usage of the word pitch, and only tends to cause unnecessary confusion. The lead of a screw thread is the distance the screw will move forward in a nut if turned around one full revolution. It is clear that for a single-threaded screw the pitch and the lead are equal, as the screw would then move forward the distance from one thread to the next if turned around once. In a double-threaded screw, however, the screw will move forward two threads, or twice the pitch, so that in a double-threaded screw the lead equals twice the pitch. In a triple-threaded screw the lead equals three times the pitch, and so forth. The lead may also be denned as being the distance from center to center of the same thread, after this thread has made one turn around the screw. In the single-threaded screw the same thread is the next thread to the one first considered. In a double threaded screw there are two threads running side by side around the screw, so that the same thread here is the second one from the one first considered.

Book excerpt: Excerpt from American National Screw Thread Tables for Shop Use, Vol. 2: Special Threads Where special threads are required, it is sometimes essential to select a certain pitch as standard for a range of sizes. Also, in general practice, Where the pitch of a special thread is optional, the uniform use of a selected pitch is advantageous. For such applications the 12 pitch is Widely used, particularly for two distinct purposes as given below, but for different reasons.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Screw Thread Kinks TO cut a left-hand thread, the handle I is lowered until gear F meshes with E. This makes L run in the reverse direction, as E, G and the intermediate run the same way. This is the Object Of the gear F, which is idle when cutting right-hand threads. Having settled the direction in which the gears run, the next question is, the gears required to produce the right thread on the work. It is easy to see that if the lathe spindle and the lead screw revolve at the same rate, the carriage will advance one thread at each revolution and cut the same thread as the lead screw. With the gearing shown in Fig. 1, this will not be the case, because the gear on the stud S has fewer teeth than the main driving gear E, so that the lead screw will turn at a slower rate, and cut a finer thread.

Tests have been conducted at Sibley College to determine the probable loads produced in standard bolts when tightened for a steam-tight joint, but no attempt has been made to determine the relations existing between this load and the total tension on the one hand, and the useful or extennal load on the other. So far as we have been able to determine, no investigations, either the oretical or experimenta1,1have ever been undertaken to discover the effects of different kinds of packing on these loads.
