IMPIIEIEMENT DESIGNED JEOR MARKING CIRCLES.
Specification of Letters Patent.
Patented (Bot. 27, 1914.
Application filed December 27, 1913. Serial No. 809,071.
To all whom it may concern Be it known that I, EGBERT S. CADY, a citizen of the United States, residing at Cedarville, in the county of Mackinac and State of Michigan, have invented new and useful Improvements iiil'rnplements Designed for Marking Circles, of which the following is a specification. The invention relates to an implement primarily designed for marking circles of desired diameter upon plain surfaces, such as black board or the like, where it is ordi narily impossible to use the ordinary type of compass with certainty as to the result.
The main object of the resent invention is the provision of a blac board compass including means for temporarily securing the center to the black board without marring the same, and means whereby any desired radius may be readily obtained and maintained during operation.
The invention in its preferred form of vdetails will be described in the following specification, reference being had particularly to the accompanying drawings, in which 2- Figure 1 is a perspective view illustrating the application of the improvement. Fig. 2
is a detail perspective of the crayon clamp. Fig. 3 is a detail sectional view through the handle and section cap.
In the accompanying drawings, the 1mend of which is provided a section cup 2 of any desired type, whereby the handle may be fixed more or less securely to the surface on which the drawing is to be made. Imme-' diately above the suction cup 2 the handle 1 is formed with an annular channel 3 in which is loosely seated a collari having terminals projectin laterall in the form of spaced ears 5. etween t e ears is pivoted a compass beam 6, having appropriate scale marks 7 thereon, which may be graduated to any desired extent and are preferably arranged on both sides and continued on the upper and lower edges of the said beam.
7 represents a clamp formed of a single strip of material having four arms 8, 9, 10
' and 11. The arms 8 and 9 are bent to form a cylindrical casing 12 into which the crayon 13 is held by the resiliency of the material,
the arms beyond the casing being bent on divergent lines as at 14 to provide for the convenient insertion of the crayon and to provide a handle for the operation of the de-.
With the parts arranged as described, it is I obvious that the handle may be attached to the black board or any other plain surface and serve as a center about which the may on may be rotated to form the circle, the clamp being freely adjustable longitudinally of the beam to arrange the crayon for thedesired radius.
What is claimed is A compass crayon clamp constructed of a single piece of material, comprising four arms projected in oppositely disposed pairs,
one pair of arms being bent to form a crayon receiving casing and projected beyond the casing on divergent lines, the arms being projected in the-opposite direction to form a member for engaging an element of the compass, said-arms being proremaining jected beyond the said member, and means I for fastening the arms in position to cause the member to. frictionally engage the element.
In testimony whereof I afix my signature in presence of two witnesses.
