UNITED STATES PATENT OFFICE
JAMES W. COIN, OF HEDLEY, TEXAS.
MINE-SWEEPER AND SHIP-SHIELD.Specification of Letters Patent.
Patented Oct. 15, 1918.
Application filed May 18, 1918. Serial No. 235,283.
To all whom it may concern:
Be it known that I, JAMES W. Coin, a
citizen of the United States, residing at
Hedley, in the county of Donley and State
5 of Texas, have invented a new and useful
Mine-Sweeper and Ship-Shield, of which
the following is a specification.
The device forming the subject matter of
this application is a mine sweeper and ship
10 shield, and one object of the invention is to
provide a device of the kind mentioned
which will be thoroughly efficient in protect-
ing a vessel against the disastrous effect of
mines, torpedoes and the like.
15 Another object of the invention is to pro-
vide novel means for collecting and catch-
ing mines while the sweeping process is un-
der way.
A further object of the invention is to
20 improve the nets and to improve the mount-
ing of the nine-catching hooks thereof.
It is within the province of the disclosure
to improve generally and to enhance the
utility of devices of that type to which the
25 present invention appertains.
With the above and other objects in view,.
which will appear as the description pro-
ceeds, the invention resides in the combina-
tion and arrangement of parts and in the
30 details of construction hereinafter described
and claimed, it being understood that, within
the scope of what is claimed, changes in the
precise embodiment of the invention shown
can be made without departing from the
35 spirit of the invention.
In the accompanying drawings
Figure 1 shows in side elevation, a vessel.
equipped with the device forming the sub-
ject matter of this application; Fig. 2 is a
40 top plan of the structure shown in Fig. 1;
Fig. 3 is a fragmental transverse section
showing a portion of a vessel whereunto the
device forming the subject matter of this ap-
plication has been connected; and Fig. 4 is a
45 fragmental elevation showing a portion of
the net.
The numeral 1 marks the hull of a vessel.
Intermediate posts 2 are located at the sides
of the hull 1 in spaced relation thereto, the
50 posts 2 preferably being located about amid-
ship. Forward posts 3 are located ahead of
the intermediate posts 2. A stem post 4 is
located immediately in front of the bow of
the vessel. Quarter posts 5 are located
55 astern of the intermediate post 2 and areshorter than the intermediate post. Stern
posts 6 are located abaft the quarter posts 5.
Referring to Fig. 3, it will be seen that the
intermediate posts 2 are connected withthe
hull 1 by struts 7 and by means of crossed 6
tension members 8 located between the struts
7. The intermediate posts 2 are connected
with the hull 1 by means of a downwardly
and outwardly inclined brace 9, located
above the uppermost strut 7. The posts 3, 65
4, 5 and 6 are connected in a like way in the
hull 1.
Referring to Fig. 4, it will be observed
that retractile springs 1.0 are connected as
shown at 11 with the intermediate posts 2, 70
the springs being connected by ties 12. Fig-
ure-8 links 14 are engaged with each other
and with the springs 10. Concatenated loop
shaped links 15 are engaged with each other
and are engaged with the interengaged por- 75
tion.s 16 of the figure-8 links 14.
Upright hooks 17 are located adjacent the
upper edge of the net defined by the links 14
and 15. The shanks 19 of the hooks 17 are con-
nected by eyes 20 with the crossed portions 80
of certain of the figure-8 links 14, the shanks
of the hooks being united by means of clamps
21 with the crossed portions of others of the
figure-S links 14. Lower hooks 22 are con-
nected in a like manner with the figure-8 85
links 14 of the net, and include upstanding
bills 23. Hooks 24 are secured in any suit-
able manner, as shown at 50, to the inter-
mediate post 2 and are provided with for-
wardly presented bills 25, the hooks 24 being 90
horizontally disposed, assuming that the ves-
sel rests on an even keel.
The construction including the springs 10,
the ties 12 and other ties 51 which connect
the figure 8-links 14 close to the springs 10, 95
and shown in connection with the posts 2, in
Fig. 4, is duplicated adjacent each of the
posts 4, 3, 5 and 6. The posts 4 and 3 are,
therefore, connected by a net 26, the posts 3
and 2 being connected by net 27, the posts 2 100
and 5 being connected by a net 28, and the
posts 5 and 6 being connected by a net 29,
all of which is clearly disclosed in Fig. 1 of
the drawings.
Although the various nets, such as the net 105
27, may be constructed as desired, the par-
ticular form of net hereinbefore described,
will be found to be peculiarly useful, and
to possess great strength. The hooks 17 and
22 serve to retain mines, torpedoes and the 1101,281,520.
