NELS E. JOHNSEN, OF CHELSEA NAVAIJ HOSPITAL, NEAR BOSTON, MASS.
IMPROVEMENT IN Specification forming part of Letters Patent No 160,100, dated February 23, 1875; application filed November 30, 1874.
To all whom it may concern:
Be it known that I, NELs E. J OHNSEN, of Chelsea Naval Hospital, (near Boston,) in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Gun-Carriages, of which the following is a specification The invention relates to new and useful improvements in gun-carriages; and it consists in the peculiar construction of a compressor or friction bar and compressing device for holding the carriage in position, and for lessening the recoil of the same when the gun is fired; also, in a novel device for locking the carriage to the compressor-bar, and in a windlass and rope mechanism for bringing the gun to and from port.
In the accompanying drawing, Figure 1 is a side elevation, partly in section, to show more clearly the construction, having the gun mounted. Fig. 2 is a top view of the carriage, the gun being seen in dotted lines. Fig. 3 is a detail, showing the construction of the mechanism for varying the trucks. Fig. 4 is a detail, showing the construction of one of the side windlasses for training and holding the 'un. g Similar letters of reference indicate corresponding parts.
The sides A of the carriage are connected at each end by cross-pieces, the forward one of which stands on edge, the front of which is represented by B. The rear cross-piece G is horizontal, at the back of which is placed the mechanism for varying the trucks. This mechanism consists of a ratchet-wheel, D, and a lever spring-pawl, E, with the gear-wheel F, which wheel meshesinto wheels G G on the ends of the shafts H H. I is a worm-wheel on the spindle-block of the rear truck J. On the shaft H is a worm-screw, K, which engages with On the forward ends of each of these shafts H H are worm screws K, which engage with worm-wheels L on the spindle-blocks of the two forward trucks M M.
By working the ratchet-bar N the shafts are revolved and the truck-wheels are turned to move the carriage to the right or left, as may be desired. The ratchet-pawl is double, and held by a spring to work in either direction. The rear truck is given an up-and-down I motion, to allow the rear of the carriage to rest upon the deck when desired. The spindle-block of this truck slips upward by the weight of the carriage, and the carriage is raised by means of the eccentric lever O, the eccentric P of which bears upon the top of the spindle-block, as seen in Fig. 1. Q is a'stationary bar, attached to the rear portion of the carriage on the cross-piece 0. Upon this bar slides a compression or friction-bar, Q, which is attached to the inside of the port by means of a pin, R. (See Fig. l.) S is a block, through which the compressor-bar passes. T is a lever-shaft, on which is the arm U, carrying a tongue or bolt, V, which enters the compressor-bar through a mortise in the block S, in order to hold the carriage in a stationary position previous to firing. W are pinions on the crank-shafts X X for revolving the Windlass Y, around which the ropes Z Z are wound for moving the gun back and forth. The pinions W W engage with the gear-wheels A, which are on the Windlass-shaft.
The ropes Z Z are attached to the rear of the port, as seen at B, and after passing around the Windlass, continue rearward, and are attached to the cross-bar G, which is attached to the block D, which slides on the compression-bar Q. E is the compressing or clamping device, consisting of a screw, F, having a worm-Wheel, G, and a worm on shaft H". I I are lever-heads on the ends of this shaft, by means of which the screw is turned down onto the bar, for holding the carriage stationary, or in position. J J are geared windlasses, which operate the ropes K K. These ropes are attached to the lugs L L on the sides of the carriage. These ropes are for training the gun right and left. When the gun is discharged the shafts of the windlasses J J are slipped along and thrown out of gear, as seen in Fig. 4. These windlasses are revolved by means of the lever-wheels M. The trunnions of the gun B are hung in blocks or plates 0, which have a sliding motion on the sides of the carriage, at the ends of which plates are placed cushion-pieces of rubber P, which prevent the contact of metal with metal when the gun is discharged. Q, are cap-plates, which confine the rubbers. The Windlass R is confined to the port by the same pin which confine-s the compression-bar, and is designed arm U, and rock-shaft T, with the compressor bar Q'and gun-carriage A, as and for the purpose set forth.
3. The combination of the Windlass Y and rope Z with the gun-carriage and compressorbar, for bringing the gun to and from port, as and for the purpose specified.
