Recoil mechanism or shock absorbers for seats <strong>of</strong> personnel<br />
and air brakes set by the recoil might well be added, 80 that<br />
the mount might be used either 8S an emplacement (base<br />
ring) or as a rolling recoil mount for coast defense, if the<br />
latter method were found necessary.<br />
487. TEN-INCH, 50-CALIBER GUN.-This mount must supplement<br />
the long guns on caterpillars on interdiction and long-range destruction<br />
work. Ii must be capable <strong>of</strong> quick emplacement, should havo<br />
a wide field <strong>of</strong> fire and should be ahle to deliver a number <strong>of</strong> shots in<br />
a minimum <strong>of</strong> time. A ·consideration <strong>of</strong> these points leads to thll<br />
following recommendations on df'.sirable characteristics:<br />
Recoil: Cradle, with pneumatic recuperator.<br />
Spur gearing with anti-friction device on the trunnions.<br />
Elevation:<br />
Ratio, 1 degree elevation per turn <strong>of</strong> handwheel.<br />
Elevation to 45 degrees.<br />
Traverse: Car traverse:<br />
On trucks for limited fire <strong>of</strong> 11 degrees.<br />
On center pintle for limited firo <strong>of</strong> 60 degrees.<br />
<strong>Railway</strong> car: Girder type.<br />
Anchorage:<br />
Rolling for 11 ddgrees fire:<br />
Track platform and struts for 60 degrees fire.<br />
Ammunition supply: Crane and shot truck.<br />
Plates 59, 60, and 438 to 448 show how this design might be worked<br />
up. While detail'i have not been investigated, enough has been done<br />
on each important feature to domonstrate that nothing is required<br />
<strong>of</strong> it beyond that required <strong>of</strong> a similar feature on an existing successful<br />
m<strong>of</strong>mt. It is helieved that this type <strong>of</strong> mount would be well<br />
adapted to emergency coast defense.<br />
488. FOURTEEN-bcH, 50-CALIBER GUN.-This mount will be used<br />
for the longest range destruction work. It will, in general, be<br />
employed some distance back <strong>of</strong> the lines, ample time will be available<br />
for placing it and its field <strong>of</strong> fire at any time is apt to be narrow.<br />
It is recommended that the carriage suggested for the 16-inch, 25-<br />
caliber howitzer be used likewiso for this gun. An elevation <strong>of</strong> at<br />
\<br />
least 50 degrees and an elevating gear ratio <strong>of</strong> 0.5 degrees per tum<br />
<strong>of</strong> the handwheel is recommended.<br />
