Abstract
A dolly system having a pair of flexible lashing straps which are tightened y a single turnbuckle. The upper clamps to which the lashing straps attach are reversible, one position having an arcuate surface with a contour matching a first weapon diameter, D1, and the other position having an arcuate surface contour matching a second larger weapon diameter, D2. The strap connection point on this double contoured clamp piece permits the same lashing straps to be used for both weapon diameters. Further, each dolly has two reversible bottom clamping pads, each with an arcuate surface contour that selectively matches either the D1 or the D2 weapon diameter. Each bottom pad is held in place with a pivot pin and a position pin, each of which is of a quick release type. The primary advantage of such a dolly system is that storage of present size weapons is relatively unaffected by providing this future growth potential.

Description
Brief Description of the Drawings
A more complete understanding of the invention and many of the attendant advantages thereto will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings wherein:
FIG. 1 shows a front view of a flexible weapon handling support system according to the present invention; and
FIG. 2 shows a front view of an alternate embodiment of the flexible weapon handling support system of FIG. 1.
Description of the Preferred Embodiment
Referring now to FIG. 1 there is shown an arrangement of weapon storage devices 10, each device 10 comprising two flexible dolly lashing straps 12a and 12b, a turnbuckle 14 which is disposed between and threadably attached to first and second upper clamps 16a and 16b, and a dolly base 18 having a preselected width W1. Lashing straps 12a and 12b connect, at the top ends 20 thereof to upper clamps 16a and 16b respectively and, at the bottom ends 22 thereof, to protrusions on dolly base 18. Dolly base 18 further includes first and second reversible pads 24, each of which are attached to dolly base 18 by means of a pivot pin 26 and a position pin 28. Dolly base 18 also has a "button" 30 mounted on the bottom surface thereof for securing device 10 to slots (not shown) in the weapon handling support structure. Upper clamps 16a and 16b are reversible. In one position the clamps have a radius R1 which matches the contour of a weapon 32 having a relatively small diameter D1, e.g., 21 inches, while in the other position a radius R2 matches the contour of a weapon 34 having a larger diameter D2, e.g., 26.5 inches. It is noted that the weapon diameters described are merely exemplary and may be varied within the spirit and scope of the invention. Due to the standoff and strap connecting point positioning of the strap connection point protrusions 36 on the double contour surfaced upper clamps 16a and 16b, the same straps 12a and 12b can be used for both size weapons. In addition, each base bottom pad 24 is reversible with the radii R1 or R2 selected to match either a D1 or D2 diameter weapon. Pivot pin 26 and position pin 28 can each be quick release type pins. The system utilizes standard weapon dolly lashing straps 12a and 12b, and well known strap release mechanisms (not shown).
It is further noted that in FIG. 1 width W1 of base 18 is less than that of weapon diameter D2 and is selected such that when adjacent dolly systems 10 are placed side by side the dolly-to-dolly spacing S1 equals W1. In this configuration, the width of the body of a weapon of diameter D2 encroaches somewhat into the area above the adjacent base 18 thus requiring that the adjacent dolly be left empty as shown in FIG. 1. Heights H1 and H2 also differ based upon the weapon diameter selected. For example, a 26.5 inch diameter was selected as the larger weapon size in the preferred embodiment in order to permit installation of acoustic material on the inside of the torpedo launch tube between the weapon and the inside diameter of a 30 inch tube barrel. As long as the larger weapon is 26.5 inch in diameter or less, this acoustic material then does not interfere with the weapon.
FIG. 2 shows an alternative configuration of device 10 of FIG. 1 in which a weapon storage device 40 employs a dolly base 42 that is wider than dolly base 18 of FIG. 1. All remaining components used in the device of FIG. 1 remain unchanged in system 40 of FIG. 2. The method of securing weapons 32 and 34 also remains unchanged; however, width W2 of dolly base 42 is increased such that W2>D2. The primary advantage of this embodiment is that the dolly support system spacing can be optimized for the larger weapons and therefore a greater number of large weapons can fit in the torpedo room. Of course, fewer D1 diameter weapons can be stored in a torpedo room configured in this manner, as no more of the small diameter weapons can be stowed in the torpedo room than can large diameter weapons thereby reducing the number of small weapons stowable by approximately the same proportion as the ratio of base growth [W2-W1]/W1 which can be on the order of 20 to 25%.
The primary advantage of a dolly system which supports two different diameter weapons is that an original ship design and stowage capability would be relatively unaffected by providing this future growth potential. This is a result of the dolly lock positions being identical for both size weapons and the support structure for the weapons then needing only to be designed for S1 or S2 dolly lock spacing. This feature provides the capability to maximize weapon storage capability with either a standard (21" diameter) or a larger diameter weapon. FIG. 1 shows that larger diameter weapons stowage is not maximized because the D2 diameter weapon is wider than dolly width W1. Therefore, no weapons can be stowed adjacent to a larger weapon. Conversely, FIG. 2 shows that standard diameter weapon stowage is not maximized because the D1 diameter weapon is smaller than dolly width W2. The impact of the increased weight of the larger weapon, however, will not affect the total structural load carrying requirements of the support structure because a smaller number of larger weapons can be stowed in the torpedo room as compared to a full room of D1 diameter weapons. While a detailed layout of a particular torpedo room arrangement would have to be made in order to determine the exact number of D2 diameter weapons that can be stowed in a particular torpedo room, it is notable that one D2 diameter weapon normally weighs only about 83% of the weight of two D1 diameter weapons of equal length and density. A second advantage over existing dolly systems is that the present dolly lashing straps are tightened using a single turnbuckle in lieu of the two tightening bolts required in the prior art systems.
What has thus been described is a dolly system having a pair of flexible lashing straps which are tightened by a single turnbuckle. The upper clamps to which the lashing straps attach are reversible, one position having an arcuate surface with a contour matching a first weapon diameter D1, and the other position having an arcuate surface contour matching a second larger weapon diameter weapon D2. The strap connection point on this double contoured clamp piece permits the same lashing straps to be used for both weapon diameters. Further, each dolly has two reversible bottom clamping pads, each with an arcuate surface contour that selectively matches either the D1 or the D2 weapon diameter. Each bottom pad is held in place by a pivot pin and a position pin, each of which is of a quick release type.
Obviously many modifications and variations of the present invention may become apparent in light of the above teachings. For example: the inventions primary intent is to show a dolly/lashing strap mechanism that can accommodate two different weapon sizes without compromising the stowage capacity for the smaller diameter weapon. The system configuration would vary depending upon the size of the larger weapon, a detail stress and shock analysis, material selection and roll stability analysis. For example, the dolly could be designed with two buttons in the lower track, in lieu of one (as shown) to improve the roll stability of the system.
In light of the above, it is therefore understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
