WILLIAM A. F. URBAN, OF YOAKUM, TEXAS.SECURING DEVICE.
Specification of Letters Patent. Patented Aug. 15, 1916.
Application filed February 12, 1915. Serial No. 7,868.To all whom it may concern:
Be it known that I, W iLrnA-r A. F.
URBAN, a citizen of the United States, re-
siding at Yoakum, in the county of Dewitt
5 and State of Texas, have invented certain
new and useful Improvements in Securing
Devices; and I do hereby declare the fol-
lowing to be a full, clear, and exact descrip-
tion of the invention, such as will enable
10 others skilled in the art to which it apper-
tains to make and use the same.
This invention has for its object to pro-
vide a novel and efficient pin or bolt having
a head at one end and a pivoted locking
15 bar at the opposite end adapted to be moved
angularly with relation to the pin or bolt
to secure the latter against removal.
Another object is to provide a securing
device including means for reliably secur-
20 ing the pivoted bar in locked and unlocked
position.
With these and other objects in view, the
invention consists in the novel construc-
tion, arrangement and formation of parts as
25 will be hereinafter specifically described,
claimed and illustrated in the accompany-
ing drawing, in which:
Figure 1 represents a side elevation,
showing the application of the securing de-
30 vice to a clevis. Fig. 2 represents a side
elevation of the pin or bolt, partly in sec-
tion. Fig. 3 represents a view similar to
Fig. 2, taken at right angles thereto.
Referring to the drawing in detail, where-
35 in similar reference numerals designate cor-
responding parts throughout the several
views, the numeral 5 indicates the shank of
a bolt or pin having a flat head 6 at one
end and a longitudinal recess or bore ex-
40 tending inwardly from the opposite end.
The recessed end of the shank 5 is formed
with diametrically opposed slots 8 in which
is positioned a locking bar 9. The bar 9
is pivoted adjacent one end in the slots 8
45 on a pin 10 extending transversely through
the recessed end of the shank.
The pivoted locking bar 9 is formed upon
opposite sides and in one end with notches
11 adapted to receive the pointed end of a
50 member 12 slidably mounted in the longitu-
dinal bore 7 and normally retained in en-gagement with the pivoted end of the lock-
ing bar 9 by the tension of a spring 13 en-
gaged at one end against the inner end of
the longitudinal bore 7 and at its opposite 55
end over a reduced extension 14 of the slid-
able locking member 12. The end of the
slidable locking member 12 which engages
with the adjacent extremity of the pivoted
locking bar 9 is tapered to provide an edge 60
15 which is adapted to engage within the
notches 11 and the edge of said member 12
is concaved, as clearly illustrated in Fig.
3, to prevent rotational movement of- the
member within the bore of the shank 5. 65
The corners of the pivoted end of the lock-
ing bar 9 are preferably rounded so as to
permit free pivotal movement thereof.
In use, the shank 5 of the securing-device
is positioned through a clevis or other ob- 70
ject to be secured by moving the pivoted
locking bar 9 to the dotted line position
illustrated in Fig. 2, and after the shank
has been properly positioned the locking
bar is swung to the full line position illus- 75
traded in Figs. 1 and 2. It will be under-
stood that the spring actuated locking mem-
ber 12 will engage within the notches of the
locking bar and thus reliably secure the lat-
ter in either locked or unlocked position. 80
What I claim is:
A securing device including a shank hav-
ing a longitudinal bore extending inwardly
from one end thereof, a head at the oppo-
site end of said shank, a locking bar piv- 85
otally secured in said shank having a plu-
rality.of notches in the pivoted end thereof,
a spring actuated locking member slidably
mounted in said bore having a tapered end
defining a concave edge engaged with the 90
edge of the pivoted locking bar to prevent
rotational movement of the spring actuated
locking member and adapted to engage
within the notches in said locking bar to se-
cure the latter in adjusted position. 95
In testimony whereof I affix my signature
in presence of two witnesses.
