WILLY GIESE, OF ROUND TOP, TEXAS.
MEASURING DEVICE.Specification of Letters Patent. Patented June 15,1915.
Application filed October 31, 1914. Serial No. 869,639.To all whom, it may concern:
Be it known that I, WILLY GIESE, a citi-
zen of the United States of America, resid-
ing at Round Top, in the county of Fayette
5 and State of Texas, have invented certain
new and useful Improvements in Measuring
Devices, of which the following is a specifi-
cation, reference being had therein to the
accompanying drawing.
10 This invention relates to a measuring'de-
vice and has for its principal object the pro-
duction of a device which is particularly
adapted to be used for drawing circles upon
the surface by the operation of the operating
15 members.
Another object of this invention is the
production of a measuring device which is
adapted to draw circles and which is so
formed as to allow the chalk carrying por-
20 tion to be adjusted or as to diminish or in-
crease the size of the circle as desired.
Still another object of this invention is
the production of a plurality of gears which
are beveled so as to allow the chalk carry-
25 ing member to be operated upon the turning
of a handle while this handle is so arranged
as to allow the chalk carrying member to
pass thereby without interference.
With these and other objects in view this
30 invention consists of certain novel combina-
tions, constructions, and arrangements of
parts as will be hereinafter fully described
and claimed.
In the accompanying drawings :-Figure
35 1 is a detailed perspective view of the meas-
uring device illustrating the manner in
which the same is used. Fig. 2 is a central
vertical section through the invention, por-
tions of the same being broken away. Fig.
40 3 is a section taken on line 3-3 of Fig. 2
looking in the direction of the arrow. Fig.
4 is a section taken on the line 4-4 of Fig.
2 looking in the direction of the arrow. Fig.
5 is a detailed perspective view of the chalk
45 carrying member. Fig. 6 is a detailed per-
spective view of the arm supporting mem-
ber. Fig. 7 is a longitudinal sectional view
taken through the chalk supporting mem-
ber and curved finger.
50 Referring to the accompanying drawings
by numerals 1 designates the central rod
which is enlarged adjacent its lower end as
shown at 2 to form a supporting shoulder 3
and terminates in the beveled point 4. The
55 supporting base 5 is positioned upon the en-
larged portion 2 of the rod 1 and has thediverging legs 6 extending therefrom so as
to support the integral ring 7. By allowing
this ring 7 to rest upon the support the rod
1 will be supported in a perpendicular posi- 60
tion so as to allow the beveled point 4 to
rest upon a certain desired point or center
when the device is in operation. The handle
8 is carried upon the upper end of the rod 1
for facilitating the carrying of the device 65
from place to place. The supporting frame
9 has the L-shaped portion 10 extending
therefrom which is reinforced by the rib 11
and has upon its outer portion the integral
bearing 12. This bearing 12 has the trans- 70
verse opening 13 through which the rota-
table shaft 14 is adapted to pass and upon
the outer end of the shaft 14 there is carried
a crank 15 having the pin 16 threaded into
engagement therewith for supporting the 75
loose handle 17. It will be seen that by grip-
ping this loose handle 17 and swinging the
crank 15 the shaft 14 will be rotated since
the retaining pin 18 passes transversely
through the crank and the shaft 14. The 80
beveled gear 20 having a neck 21 extending
therefrom is held in a set engagement with
the inner end of the shaft 14 by means of the
pin 22 which passes through the neck 21 and
the shaft 14 adjacent the inner end thereof. 85
Another beveled gear 23 having a neck 24
is positioned upon the post 1 so as to allow
the neck 24 to rest upon the shoulder 3 of
the rod 1 and upon the upper surface of the
stand 5. This beveled gear 23 meshes with 90
the beveled gear 20 whereby when the shaft
is rotated by the crank 15 the beveled gear
20 will impart rotary motion to the bev-
eled gear 23. The arm supporting member
25 comprises a collar 26 which supports a 95
bifurcated end 27. This collar 26 embraces
the neck 24 of the beveled gear 23 and is
held in engagement with the neck of the
beveled gear 23 by means of the set screw
28. The bifurcated end 27 is adapted to 100
carry the elongated arm 29 by means of the
pivot pin 30 which passes through the alined
apertures 31 of the bifurcated end 27 and
passes through the arm 29. Upon this arm
29 there is carried a sectional sleeve 32 105
which is held in a set position upon the
arm 29 by means of the set screw 33. This
sectional sleeve 32 is provided with parallel
spaced lugs 34 between which fits the curved
finger 35. This curved finger 35 is held in 110
position by means of the pivot pin 36. A
flat spring 37 is secured to the upper por-1,143,531.
