The threads of the screw are shown the way they really appear, but the student can draw them in the conventional way explained in Art. The kkba of all beginners is to use both hands for operating the com- passes. The floorbeams are shown broken off and should be made about the same length in proportion to their depth as they appear on the plate. The inner circle of plan is the projection of the inner- most points of the ring which form a circle whose diameter is A B. The actual projec- tion of a screw thread will be similar to the projection of a helix ; but in order to save the time required to locate the points and trace in the curves, the following methods are universally used, except, perhaps, in the case of screws of very large diameter and pitch, drawn full size.

Faezuru The number of threads per inch on the nipple shown is G shows a top view, longitudinal section, and cross- section of the front jaw. This may be conveniently done as follows: In the large shops, however, separate drawings are often made for the patternmaker, blacksmith, and machinist ; the detail drawing for the use of the patternmaker, then, contains only the dimensions and notes needed by him to make the pattern; that for the blacksmith contains the dimensions needed for making the forging; and, finally, that for the machinist contains all dimensions needed by him.
The head A is placed against the left-hand edge of the board, as shown in Abw. Notice that the figures are not made as in writing, particularly the 6, Jf, 8, and 9 see Fig. To draw it, proceed exactly as in the last figure. In all good instruments, the needle point itself is a separate piece of round steel wire, held in place in a socket provided at the end of the leg.
Through B, C, etc. The pitch, or distance that the screw would advance in one turn, would be f of an inch, the same as if it were a single- threaded screw of f an inch pitch, while the depth of the thread is only half as great.
The Polk County Democrat January 2, The remaining figures are drawings of the different parts, or details. Draw the two diameters A E and G C at right angles wbe each other. Test the ink occasionally to see if it is black. The thread, however, is right-handed, and the reason for show- ing it in this manner is that it is the bottom of the thread that is being looked at; that is, the section of a right- handed nut is the same as the projection of the top of a left-handed screw.
The right-hand portion of Fig. Owing to the want of room, only that half of the development is shown which contains the part to be cut out. With the same radius that was used to describe the orig- inal circle, describe part of another circle, being careful not to run over the first circle, and stop- ping when the two lines coincide.
These features are found on most of the other capitals. GO is shown a per- spective view of a frustum of a pyramid having a rectangu- lar base and a hole passing through the center of the frustum. This IS not a true ellipse, but is very convenient for many purposes.
In mechanical drawing, all headings, explanatory matter, and dimensions should be neatly printed on the drawing. Do not punch large holes in the paper with the dividers or com- passes. Such information may not reliably predict data collected via systematic evaluation of the efficacy in company-sponsored clinical trials.
In the W the two outside lines are not parallel, as in the M, but are farther apart at the top than at the bottom. Examine the points frequently, and keep at work until the pen will draw both fine lines and smooth heavy lines. Moreover, data from such small numbers of patients may be highly variable. It is very important that all the letters have the same inclination.
When the screw thread is hidden by part of the object and it is deemed necessary to show it in dotted lines, it is usually drawn in one of the four ways illustrated in Fig.
Sometimes even this is not done, but a note is placed on the drawing calling attention to the fact that some certain part of the object is to be repeated. A protractor is shown in Fig. Wheel of Speed The pen must not be pressed against the edge of the T square or triangle, as the blades will then close together, making the line uneven.
Divide the circle which represents the base of the cone in the plan into any number of parts, in this case 24, and, through the points of division A, E, 77, etc. To find the side elevation, proceed as follows: In some cases, draftsmen will draw a dotted line or a full red line at a little distance from the outline and write f across it ; it is usually under- stood, in that case, that the lengths of the supplementary lines denote the extent of the surfaces that are to be finished.
With any other point D in the given arc as a center, and the same radius, describe an arc intersecting the first in O. After the erasure has been made, the roughened part of the surface of the paper can be smoothed by rubbing with some hard, smooth substance, as a piece of ivory or the handle of a knife. The dotted curves need not be drawn by the student, as they are merely put in to show the connections between the different threads.
This drawing shows the figure as it would look if the eye were directly over it. If more than one scale is used, as in the last plate, where three dif- ferent ones were used, it should be given for each figure.
The mere presence of these lines shows in most cases that part of the object through which they are drawn is round. This plate shows the different forms of the curves formed by the intersection of a cone or cyHnder by a plane. A curve traced through the points thus found will be the required projection of the upper base of the cylinder. It is well to ink in all the perpendicular lines first, next the horizontal lines, and then the oblique lines.
