4 Claims.
The present invention relates to new and useful improvements in carpenters square and has for its primary object to combine therewith a compass including an adjustable leg by means of which circles of different radii may be drawn.
An important object of the present invention is to provide a device of this character which includes a stationary prong forming one point of the compass and embodying clamping means carried by the prong for securing the adjustable leg of the compass in a desired adjusted position.
A further important object is to provide a carpenters square in which the leg portion thereof is formed with an angular stop adapted to abut the work against which the square is placed.
A still further object is to provide a device of this character of simple and practical construction, which is neat and attractive in appearance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a bottom plan view.
Figure 2 is a side elevational View.
Figure 3 is an end elevational view.
Figure 4 is a fragmentary sectional view taken substantially on a line 4--4 of Figure 1.
Figure 5 is a plan view of the adjustable leg of the compass.
Figure 6 is a fragmentary perspective view of the outer end of the adjustable leg of the compass showing the marking prong projecting therefrom.
Figure 7 is an end elevational view thereof.
Figure 8 is a side elevational view of the combined pivot point and clamp for the adjustable leg of the compass.
Figure 9 is an edge elevational view thereof.
Figure 10 is an end elevational view thereof showing the pivot prong, and
Figure 11 is an end elevational View of the 0pposite end thereof.
Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates the square generally which includes the base portion '5 and leg portion '5 extending at right angles therefrom. The leg portion I is formed of a thin steel strip having its inner end bent downwardly at right angles as shown at 8 to form a stop for placing against the work during use of the square. The upper surface of the leg portion 1 of the square is marked with graduations 9 in inches and fractions thereof. A brace Ii] connects the outer end of the base 6 with the leg portion I adjacent its outer end.
The leg portion I is formed with a longitudinally extending slot II in which is slidably positioned a downturned lug I2 formed on the outer end of an adjustable compass leg I3, the leg being slidably mounted in an opening I l formed in the base 6 of the square.
A cross bar I5 projects laterally from each side of the leg I3 adjacent its outer end to overlie the graduations 9 of the square and struck from the cross bar I5 is a prong I6 projecting upwardly beyond the surface of the square.
A bolt I'l extends through the base portion 6 of the square having a head I8 at one end thereof adapted for clamping engagement with the leg I3, th head l8 being held against the leg I3 by means of a wing nut I9 threaded on the bolt. The head I8 also includes a prong 20 also projecting upwardly beyond the square and cooperating with the prong I6 for use as a compass by inverting the position of the square and utilizing the prong 20 as a pivot.
It is believed the details of construction, advantages and manner of use of the device will be readily understood from the foregoing without further detailed explanation.
. Having described the invention, what is claimed as new is:
1. A compass comprising a flat, elongated body having a fixed pivot at one end, a compass leg having a prong at one end and having its other end slidable longitudinally in the body, and means formed as a part of the fixed pivot and engageablewith the leg for securing the leg in adjusted position on the body.
2. An attachment for a tool of the class described comprising a bolt carried by the tool and having a head, a prong on the head projecting from one surface of the tool, a leg slidably carried by the tool and engaged under the head of the bolt to secure the leg in adjusted position, and a prong on the outer end of the leg extending in a direction parallel to that of the first prong.
3. An attachment for a tool of the class described comprising a bolt carried by the tool and having a head, a prong on the head projecting from one surface of the tool, a leg slidably 10 prong. y from one; surface of the; tool, said tool having a 1 slot, a leg having a lug slidably mounted in the slot, one end of the leg being engaged under the head of the bolt to secure the leg in adjusted position, said leg being disposed parallel to one edge of the tool and said slot having graduations adjacent the edges thereof, a cross bar on the other end of the leg overlying the graduations, and a prong on the cross bar extending in a direction parallel to that of the first EMERY DAYTON DILLON.
