Specification of Letters Patent.

Application filed December 10, 1915. Serial No. 66,133.

To all whom it may concern:

Be it known that we, LEIGHTON N. D. MIXSELL and learns P. MADDEN, citizen of the United States and subject of the King of England, respectively, residing at Bethlehem, Northampton county, State of Pennsylvania, have invented certain new and useful Improvements in Gun-Mountings for Submarines, of which the following is a specification.

This invention relates to gun mountings and more particularly to mountings for dis structure decks; Fig. 2 is a planjof the same; and Fig; 3 is an elevation of the mechanism looking toward the breech of the gun.

Referring to the drawings, 10 indicates the main shell or deck of the boat and 11 the superstructure provided over the main deck to form a chamber within which the gun may be housed when not in use, as when the boat is submerged. The superstructure 11 is provided with an opening 12 preferably of rectangular shape and of the minimum size permitting the movement of the gun therethrough. It will be understood that the opening 12will be provided with a suitable cover to exclude water when the boat is submerged. Brackets 13 are secured to the under side of the superstructure deck 11 at one end of the opening 12 and a substantially V-shaped' member or arm 14: is pivoted to the brackets 13. The arm 1 1 is provided at 15 with a socket for the gun pivot 16, the axis of the gun pivot being at an obtuse angle to the plane of the arm 14. The details of the gun and the pointing and train ing mechanism thereof may be of any suitable construction and as they form no part of the present invention a description thereof is omitted. The gun 17 has the usual trunnion connection with the supporting plvot l6 and is adapted to swing from the full line position shown in Fig. 1 to the posrtron shown in dotted lines at 18 when it is desired to house the gun. It will be understood'that the gun will be capable of being elevated from the full line position, Fig. 1, to the various required firing angles. Seats 19 and 20 are pivotally mounted on the gun pivot 16 at 19 and 20, respectively, and, as will be readily seen from Fig. 2, the seats may be folded to a substantially vertical position to permit the gun to pass through the opening 12. One of the seats is for the gun pointer and the other for the gun trainer, and each is provided with a foot rest 21.

A substantially A-shaped frame or link member 22 has its upper end trunnioned to the member 14 on opposite sides of the socket for the gun pivot 16, as indicated at 23 in Fig. 8. The lower end of the frame 22 carries rollers 24 and 25 which run in guides 26 and 27, respectively, secured to the main deck 10. As will be seen from Fig. 3, the

. guides 26 and 27 are widely spaced apart to give substantial support to the gun.

From Fig. 1 it will be seen that by moving the lower end of the frame 22 along the guides 26 and 27 the member 1 1 will be raised and lowered. When the gun is in the firing position, as shown in full lines in Fig. 1, the lower end of the frame 22 is on the opposite side of the axis of the gun pivot 16 from the pivots of the brackets 13 and thus there can be no tendency for the gun mounting to collapse when the gun is fired. For the purpose of moving the lower end of the frame 22, any suitable mechanism may be provided and there is illustrated in the drawings a cylinder 28 secured to the deck 10 and having a piston 29 which is connected with the frame 22, at the point 30, by means of the rod 31. By admitting air or other pressure fluid tothe cylinder 28, the piston 29 may be actuated to move the lower end of the frame 22. In Fig. 1 the extreme positions of the frame 22 are shown, the full line position indicating the firing position of the gun and the dotted line position indicating the housed position of the gun. It will be understood that before the gun is housed it must be depressed to the angle indicated in dotted lines at 18, as described hereinabove.

Having thus described the invention, what is claimed and desired to be secured by Letters Patent is:

1. In a gun mounting, the combination of an arm to which the gun is pivoted, means, pivotally connecting said arm with a support so that the arm is adapted to swing in a vertical plane, a frame pivotally connectedwith said arm adjacent the gun pivot, fixed guides for the lo wer end of said frame, and means connected with the lower end of said frame and adapted to move the latter in said guides to raise and lower said arm.

2. I11 a gun mounting, the combination of an arm provided at one end with a socket for the gun pivot, means pivotally connecting the opposite end of said arm with a support so that the arm is adapted to swing in a vertical plane, a frame pivoted to said arm on opposite sides of said socket, fixed guides for the lower end of said frame, and means connected with the lower end of said frame and adapted to move the latter in said guides to raise and lower said arm. 3. In a gun mounting, the combination of an arm provided at one end with a socket for the gun pivot and at its other end with spaced members, means pivotally connecting said members with a support so that the arm is adapted to swing in a vertical plane, a substantially A-shaped frame having one end pivoted on opposite sides of said socket, fixed guides for the lower end of said frame, arranged below the connection between said members and said support, and means connected with said frame and adapted to move the same in said guides to raise and lower said arm.

4. In a gun mounting for submarines, the combination with the main deck and the superstructure deck arranged thereabove and forming a gun chamber, brackets on the under side of the superstructure deck, fixed guides on the main deck, a substantially V- shaped member having its arms pivoted to said brackets and having at its opposite end a socket for the gun pivot, a substantially A-shaped frame having one end pivoted to said member on opposite sides of said socket, the opposite end of said frame cooperating with said guides, and means for moving said frame in said guides toraise and lower said member.

5. In a gun mounting for submarines, the combination with the main deck and the superstructure deck, the latter having an opening through which the gun is adapted to pass, of an arm having spreading members and a socket for the gun pivot brackets secured on the underside of the superstructure deck and pivotallyconnected with said spreading members, one or more guides on the main deck, a member having one end pivoted to said arm and its other end movable in said guide or guides, and means connected with said member and adapted to move the same to raise or lower said arm.

6. In a gun mounting for submarines, the combination with the main deck and the superstructure deck, the latter having an opening through which the gun is adapted to pass, of an arm having spreading members and a socket for the gun pivot, the axis of the gun pivot making an obtuse angle with the plane of said arm, brackets secured on the under side of the superstructure deck and pivotally connected with said spreading members, one or more guides on the main deck, a member having one end piv oted to said arm adjacent said socket and its other: end movable in said guide or guides, and means connected with said member and adapted to move the same to raise or lower said arm.
