Description

SCRIBE HOLDING RULER Filed May 8, 1946 Inventor fiwifirz'e 15. Stone I WWW m Patented Nov. 29, 1949 UNITED STATES PATENT OFFICE 1 Claim.
1 This invention relates to new and useful improvements and structural refinements in straight edges for try-squares, and the principal object of the invention is to .provide a device of the character herein described, which will substantially decrease the utility of conventional try-squares by providing the same with a marking instrument.
A further object of the invention is to provide a straight edge which is adapted to receive any one of a plurality of marking instruments, such as may assume the form of pencils, scribes, glass cutters and the like.
Another object of the invention is to provide a straight edge in which the marking instruments are readily interchangeable and which, as a whole, may be easily applied to or removed from the try-square.
An additional object of the invention is to :provide a marking device which does not, in any way, interfere with the conventional operation of the straight edge and square.
A still further object of the invention is to provide a straight edge which is simple in construction and which will readily lend itself to economic manufacture.
With the above more important objects in view, and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which- Figure 1 is a developed view of the straight edge forming blade,
Figure 2 is a top plan view of the invention,
Figure 3 is a side elevation thereof,
Figure 4 is a top plan view, illustrating the invention in association with a try-square,
Figure 5 is an end view of the invention, and
Figure 6 is an elevational view of a marking instrument used in the invention.
Like characters of reference are used to designate like parts in the specification and throughout the several views.
Referring now to the accompanying drawings in detail, the invention embodies in its construction a blade 10, :provided with the conventional graduations l I and being formed at one end thereof with an integral extension I2, configurated substantially as shown.
2 The extension I2 is angulated and arcuated to provide a substantially tubular socket I3, this being accomplished by bending the extension upwardly from the phantom line H! and twisting the portion iii of the extension i2, as is best shown in Figures 3 and 5. The substantially square portion it of the extension is then arcuated as shown, to provide the substantially tubular body portion of the socket I3.
It will be noted that the socket is disposed on one side of the blade Ill and extends in a perpendicular relationship with respect thereto. Furthermore, the longitudinal axis of the socket i3 lies in the plane of the adjacent end ll of the blade, from which end the graduations H are calibrated.
The marking instrument l8 may assume the form of a pencil, a glass cutter, .a scribe, or the like, and is slidably receivable in the socket 13. A suitable set-screw l9, positioned in the side of the socket .and engaging the instrument I8, is employed for releasably retaining the instrument in position.
It will be noted that since the axis of the socket l3 lies in the plane of the end H, as aforesaid, the pointed extremity 2B of the instrument I8 will coincide with the end I! and hence, with the O of the graduated scale I I.
The remaining side of the blade I0 is provided with a suitable, longitudinally extending groove 2 l, this coacting with the conventional try-square 22, with which the invention may be employed.
When the invention is placed in use, the square 22 may be adjusted upon the blade in with respect to the graduated scale ll, whereupon the marking instrument it may be employed for inscribing the required lines on the work. It is believed that the various applications for which the invention may be employed will be clearly apparent from the foregoing disclosure and according- 1y, further description thereof at this point is considered unnecessary.
While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combina tion, and arrangement of parts may he resorted to without departing from the spirit and scope of the invention as claimed.
What I claim as my invention is:
