Specification of Letters Patent.
Patented June 2 3, 1914.
Application filed December '7, 1912. Serial No. 735,891.
To all whom it may concern:
Be it known that I. VVALTER G. CLASSON,
a citizen of the United States, residing at Leominster, county of \Vorcester, State of Massachusetts, have invented an Improvement in Triangles, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like arts.
p This invention relates totriangles such as draftsmen use, and it has for its object to provide a novel triangle with a sliding scale which facilitates greatly the operation of plotting out streets, lots, houses, etc.
I will first describe one embodiment of my invention and then point out the novel features in the appended claims.
Referring to the drawings, Figure 1 is a perspective view of a triangle embodying my invention; Fig. 2 is a section on the line :c:c, Fig. 1; Fig. 3 shows how the triangle may be used for plotting lots, houses on lots, etc.
1 designates a triangle such as draftsmen commonly use and which is provided with the two edges 2 and 3 extending at right angles to each other as usual in triangles. Slidably on the triangle and adjacent each of the edges 2 and 3 is a sliding scale, said scales being designated 4: and 5, respectively. Each scale is mounted to move longitudinally of and parallel to the adjacent edge of the triangle, and the outer edge 6 of the scale comes flush with the edge of the triangle. These sliding scales 4 and 5 are preferably provided with bevel surfaces 7 which are properly graduated, and they are mounted on the triangle so that they can be reversed. There are various ways in which these scales may be secured to the triangle. As herein shown the triangle has rigid therewith two dove-tailed tracks 8 and the sliding scales are each made with dovetailed grooves 19 to fit the tracks." The tracks are so arranged that each scale can move clear to and beyond the right angle edge of the triangle which stands perpendicular to the scale, that is, .the scale a can be moved into the dotted line position to project beyond the edge 3 and the scale 5 can be moved so as to project beyond the edge 2. I secure this end by making the ends 9 of the tracks 8 situated a distance from the right an "is edges of the triangle equal at least to t e Width of the scale, so
that each scale can move by the end of the track on which the other scale is mounted. These sliding scales will preferably he graduated on their edges to represent a scale of an inch to the foot or a quarter of an inch to the foot, or any other similar reduction.
A triangle having this invention is especially useful in plotting streets, lots, houses on lots, etc, as shown in Fig. 3. Assuming that 10 is a sheet of paper on which street, lots and houses are to be laid out, and that 11 represents the street and it is desired to lay off on one side of the street lots with fifty feet front and one hundred and fifty feet deep and that it is desired to lay out the plans of houses on said lots, this can be rapidly done with my improved triangle by placing the hypotenuse of the latter against the positioning triangle 13 so that the right angle sides 2 and 3 of my triangle stand at right angles and parallel to the street, respectively, as seen in Fig. 3. In laying off a lot one hundred and fifty feet deep, the scale 4 can be moved along the edge 2 of the triangle to bring a graduation point of the scale on the edge of the street and then the desired length for the depth of the lot can be laid off directly from the scale. Assuming that the back line of the lot as measured from the scale 1 comes to the point 16, then the triangle can be shifted on the positioning member 13 to bring the edge 3 thereof in line with the point 16 thus laid 05, and by using the scaled the width of the lot along its back line can be quickly marked 0E, and at the same time the back line of the lot can be drawn. In the same way lot after lot can be quickly laid off without the necessity of using dividers for measuring ofl' distances and plans of houses can be plotted on the lots in the same way Without the necessity of using dividers.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A right-angled triangle having a sliding scale member adjacent each of the two edges forming a right angle and means for sustaining each of said members for movement parallel to the edge of the triangle, said means permitting each member to be adjusted to and beyond the edge adjacent which the other member is situated.
2. The combination with a right angled triangle, of a reversible scale member slidably mounted on each of the two edges fornr ing a right angle, each scale member having its edge flush with the corresponding edge of the triangle in both of its positions, means for sustaining each of said scale members for movement parallel to the edge of the triangle, said means permitting each member to be adjusted to and beyond the edge flush with which the other member is situated,
3. A right-angled triangle having a track rigid therewith adjacent each of the two edges forming a right angle, a scale slidably mounted on each track, each track terminating short of the path of movement of the other scale whereby each scale may slide by the end of the other in the same plane therewith.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
