M, M. SZABO sept. 19, 195o RULER Filed Nov. 24, 1947 l l M, IJII Patented Sept. 19, 1950 UNITED STATES PATENT OFFICE 1 Claim. 1
This invention relates to new and useful irnprovements and structural refinements in rulers, and the principal object of the invention is to provide a ruler of the character herein described, which includes in its construction a strip of nonslipping material to prevent the ruler from sliding on the work, particularly on inclined or vertical surfaces.
A further object of the invention is to provide a ruler which, by virtue of the construction above outlined, may be eiiectively employed by stenographers, or the like, as a place marker, so to speak, While copying.
Another object of the invention is to provide a ruler which is simple in construction, pleasing in appearance and which will readily lend itself to economical 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 plan View of the invention, the same being partially broken away to reveal its construction.
Figure 2 is an edge view thereof.
Figure 3 is a cross-sectional view, taken substantially in the plane of the line 3-3 in Figure 1, and
Figure 4 is a fragmentary perspective view of the ruler with the non-slipping band removed.
Like characters of reference are employed to designate like parts in the specication and throughout the several views.
Referring now to the accompanying drawings in detail, the invention consists of a ruler designated generally by the reference character I0, the same embodying in its construction the usual straight-edged strip II having upper and lower surfaces I2, I3 respectively, the upper surface I2 of the strip being bevelled as at I4 and inscribed with a scale I5, as will be clearly apparent.
The essence of novelty in the invention resides in the provision of a longitudinally extending channel-like groove I6 in the lower surface I3 of the strip II, the groove I6 being formed by removing a longitudinal edge portion of the strip, l
as is best shown in Figures 3 and 4.
A band of resilient and non-slipping material I'I is secured by adhesive, or the like, in the groove I6, the band I'I simply being formed of rubber, or similar material, and it should be noted that the groove I6 is cut in such manner that one longitudinal edge portion I8 of the band projects It should be understood that the band II possesses sufficient resiliency to permit the lower surface I3 of the ruler to come in contact with the work, if desired, this, of course, being accomplished by exerting downward pressure upon the upper surface I2 of the ruler, as will be clearly understood.
It is believed that the advantages and use of the invention will be clearly apparent from the foregoing disclosure and accordingly, further description thereof at this point is deemed 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, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
Having described the invention what is claimed as new is:
In a ruler, the combination of a straight-edged strip provided on its under surface at one longitudinal edge thereof with an open-sided groove, and a band of resilient material secured in said groove, said band being rectangular in cross-section and having an outer longitudinal edge which normally projects below the under surface of said strip whereby the latter is supportable in a transversely inclined position, said band being depressible and expansible laterally out of the open side of said groove by downward pressure on said strip whereby the latter may assume a horizontal workengaging position.
