PVLOTTING DEVICE FOR CIVIL ENGINEERS.
specification of Letters Patent. 1 atented-Oct,k 26, 1920,
vApplication filed April 9, 1917. Serial No. 160,849.
To @ZZ whom @it may concern Be it known that I, FRANK CNAnii, aciti-` zen of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements inv Plotting Devices for Civil Engineers, of which `the followingis a specification.
My invention relates to devices for plotting cross sections in civil engineers work; and the objects of my invention are- Firstto provide a convenient means for holding the ci'oss section paper; second-a means for readily locating points on the crossssection paper, both vertical and horizoiital in relation to the transit line, and in relation to datum, the elevation of which is known, by employing two graduated scales slidably mounted in a frame, located above the crosssection paper; third-by plotting rod readings instead of elevations, to obviate the necessity of subtracting the rod reading from the height of the instrument; and fourth-to provide a means for mounting the scale carrying frame above the crosssection paper, whereby the two scalescan be adjusted in perfect alinement with the lines on the paper.
I attain these objects by the mechanism shown in the accompanying drawings in which- Figure 1, is a plan, Fig. 2, is a section on line C-D, Fig. 1, Fig. 3, is a longitudinal section on line A-B, Fig. 5, Fig. 4, is a front elevation, Fig. 5, is a left side elevation, Fig. 6, is a plan of the adjusting means for vertical scale, and Fig. 7, is a section of adjusting means for vertical scale, on line c-D, Fig. i.
Similar numerals referto similar parts throughout the several views.
The table, 1, rounded downward on all four sides and provided with two transverse ribs, 2, and 2a, forms the main frame of my device. Upon the outer surface of the rib, 2, are located brackets, 3. The outer ends of -said brackets are bifurcated forming bearings for a roller, 7, hereinafter more fully described. To the outside of rib, 2a are hiiigedly secured brackets, 4, provided with pins, 5, said pins adapted to revolubly secure a roll of cross-section paper, said pa` per being passed over the top of the table, 1, and under the plotting frame, 17, and
5s rolled on to the roller, 7, when using paper longitudinally of the table. When desirable to use paper across the table from backto front, two pins, 8, and 9 are provided projecting inward from adjacent the rear ends of the ribs, 2, and l2a. The pin, 8, is secured at the rear end to the rib, 2, and a bracket, 10,su.pports the front end a distance from the point. The pin, 9K`passes through the rib, 2, and-the bracket, 11, and is provided with a knob, 12, on the outer end. A spring, 13, is disposed onthe pin, 9, between the rib, 2",and a collar, 14, adapted to hold the pin forward and the knob, 12 against the outside of the rib. The paper on a roll held between the pins, 8, and 9, passes over the table, 1, from back to front and is wound upon the roller, 15. The front ends of theribs, 2, and 2, extend forward of the table, 1, and are rounded vertically. Approximately the center of the projecting ends of the ribs a bearing is formed for the roller, 15, which is secured in revoluble position by the pins,
ing in length, their form and construction being for a particular purpose, namely; to grip cross-section paper at any point without mutilating or injuring the lines or surface in any manner. To secure this result the rolls are built in 'two sections inside of Vthe bearings and faced with felt or similar material and the sections secured together and in contact with the paper by the sliding rings, 19. n
IThe plotting frame, 17, comprises side and end rails, 20 and 21. The side rails, 20, are rabbeted at their upper inner edges and faced on the bottom with felt, 22, forming a .guide or track for the ends ofthe runner,
23 to the bottom of the runner scale, 24, which is slidably secured by means hereafter described. The said runner is. built of metal, preferably aluminum and is in.
29 extending the entire length of the topadapted to secure in slidingv relation a scale, 30, which is retained in contact with the band, 26, by the cover, 31, and the screws,
28. The entire plotting frame, 17, is secured to the table, 1, by a thumb screw, 82, through one leaf of hinge, 33, and adjustingscrew,
ico
34. The frame 17, is pivoted on thumb screw 32, and by loosening the adjusting screw 34, it can be swung diagonally of the table. A plate, 35, is secured to the upper edge or" the runner, 23,` and isi-marked with lines, 36 and 37, corresponding to the edges of the scale, 24. The entire bottom` surface of the plotting frame is covered with felt or suitable material, 38. The sca-le, 24', before mentioned, is attached to the bottom of the runner, 23 by means of one or more rivets, 39, passing upward through the scale and a longitudinal slot, 40, in the runner, and secured to a plate, 41. Slidably disposed on top of runner bar lugs 42 are located a distance from the ends of the slot, 40, and a screw, 43 is revolublymounted between said lugs. A half nut cap, 44, is secured by a hinge pin, 45, to knuckles, 46 on the plate, 41, adapting the half nut of the cap to mesh with the thread of the screw, 48, for adrunner and means for adjusting said scale in relation to the center bar. v
In testimony whereof I affix my signature in the presence of two subscribing witnesses.
