IMPROVEMENT IN OPERATING ORDNANCE.

Specification forming part ol" Letters Patent No. 5 Il A75, dated Dccenilier l2, 1565.

To all fwho'ml it 'may concern.'

Be it known'that I, CHARLES PERLEY, ot the city and State of New York, have invented an Improvement in Operating Ordnance; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference bein g had to the annexed drawings, making part of this specification, wherein- Figure 1 is a transverse section, representing a vessel in which is a cannon Iitted with my improvements. Fig. 2 is asection of the cannon and carriage. Fig. 3 is a plan of said cannon and Qcarriage, and Fig. l1. is a rear elevation ofthe saine.

Siniilar marks of reference denote the saine parts.

My invention relates to operating` ordnance by hydraulic power 5 and it consists, first, in sustaining the gunor mortar on a hydraulic rain, so that it may be raised or lowered at pleasnre for loading behind a breastwork or protection and elevating for firing, and on which ram the gun can be turned or swiveled at pleasure with butlittle friction, in consequence ot' being sustained by the water, second, in a hydraulic recoil-check that consists in a plunger to press water out of a cylinder or chamber through an opening or openings, and thereby gradually stop the recoil of the gun 5 third, in projecting thc gun or forcing it forward (after being loaded) by means of hydraulic pressure applied to a plunger to press it along in a water-chainber and drive the gun forward by means of such plunger; fourth, in adjusting or sighting the gun by hydraulic power acting through a plunger or rod in a water-chamber to raise the cascabel or allow it to descend by the escape of water; and, fifth, in the elevatoii ot' the charge by a hydraulic carriage that is fitted in a position to `coincide with the end ofthe muzzle when elevated, so that the projectile can be rolled upon this carriage, and then raised to the muzzle and forced in with great facility.

In the drawings, a is a hydraulic pump actuated by competent means, (an engine is preferable,) and said pump is to be constructed in any usual or desired manner, and, being well known in the arts, requires no further description.

A well or water-tank is to be provided' in any convenient place. I have represented the same at b, and I remark that this apparatus may be actuated by any other duid or liquid,

suoli as alcohol, petroleum, or oils, althougliin the description the terni water77 geneially will he used.

c is a cylinder that is to extend in a vessel froni one deck to the other, or it niay pass through the niain deck and rest on the keelson, as shown. In this cylinder c is a rain, d, which forms the pivot of the gun, and on which it turns or swivels, and by which it is raised or lowered. In consequence of having this pivot or pintle pass through the deck and supported below, the gun-deck is not strained by the weiglitot' the gun, and only has to sustain the piiitle against the recoil. The hydraulic cylinder' c is provided with a packing, as usual,

and the ani at the part passing through the packing is to he of a size adapted to snstaiii the weight ot' the gun with a given pressure per square inch on the water; lint the upper part of said ram,\vhich forms the pivot or piiitle, should be larger, as shown, so as not to be damaged by a shot, it' struck by the saine. The upper end of this pintle is formed with a hed, c, upon which are parallel edges or slides for the guncarriage j", supporting the gun g hy the trunnioiis, or in any usual manner.

I provide a water-cylinder, h, and a plunger, i, the cylinder or chamber 7L being connected by means of a hole, l, to the water in the hydraulic cylinder c, and the pl unger 'i bei ng attached to the gun-carriagej".

rlhe parts thus far described are to be operated as follows: The water is allowed to escape from the cylinder c by any suitable valve, so as to lower the gun for loading. After this is done, and it is desired to prepare the saine for firing, the gun is raised bodily by the hydraulic rain as water is pumped into the cyliiider c. The gun is slid forward, either before or after or while being raised, by opening a cock or valve, 2, and allowing the pressure of water to act in the cylinder li to force out the plunger t' and force the gun forward. A stop may be provided at 3 to prevent the gun going too far. When the piece is in position for firing, the cock 2 is to be closed and a cock or valve, 4, opened. When the firing takes place the recoil of the gun drives the plungerz' back into the water-chamber h, ejecting the water through 'the valve or cock 4, and according to the size of opening couipared with the plunger and recoil-force, so the gun can be entirely stopped in running back a greater or less distance.

The liquid ejected in the recoil may be conveyed back to the tank b by a pipe or liexible tube. (Sec dotted lines, Fig. l.)

The recoil may be checked by driving the water back into the hydraulic cylinder. In this case the water-passages would require to be large and curved where they change directions, and the size of the plunger must be proportioned to the force of recoil and the pressure in the cylinder c, because the recoil-plan ger will in'this case act like a pump, and in throwing the water back into the hydraulic cylinder slightly raise the gun itself'.

In order to raise or lower the gun for taking aim, I employ a cylinder, 7e, connected to the hydraulic cylinder or correspondin g water-supply; and Zis a plunger acting against or attached to the cascabel. rlhe water is admitted under pressure through a valve at 5, to raise the back end of the gun, or it may be allowed to run out, for lowering the same, by turning the valve 6.

I prefer that the cylinder 7c be mounted on a swinging hollow center, as represented, so as to allow the ingress and egress of the liquid at the Asame time that the cylinder may swing to accommodate the movement of the cannon on its trunnions.

I have represented the supply of water as passing' through the plungerz' and gun-carriage j" to the cylinder k, as this will allow ot' the water under pressure reaching the said cylinder k with ease, notwithstanding the provision for said carriage f moving on the bed c.

It will be evident that by this means the largest-sized gun can be handled by one man, the hydraulic pump being kept in motion by power. In this'case, however, it would he necessary that valves for allowing the water to pass into or escape from the hydraulic cylinder c should be connected to the place where the gunner sta-nds, that he may have the whole under his immediate control and within reach; and I do not limit myselfl in any respect to the arrangement of valves and water-ways, as these must depend on the size and character of gun and the location where the same may be placed, as my improvement is adapted to fortifications as well as to vessels.

The red lines in Fig. l represent the improvement as applied to guns on the main deck, adapted to firing out ot' port-holes; and it will be evident that my improvement has great advantages for vessels over the present mode of mounting guns, becauselashing is dispensed with or almost entirely, the gun being always in place, and when not in use can be retained with the center of gravity exactly over the center of the pintle by means of a screw to clamp the carriage to the bed e hence there will be no tendency for the gun to swing around, no matter how much the vessel may roll.

The appratus for raising up the charge is shown at in, and consists in a plunger or rod, a, in a hydraulic cylinder, o, that is connected by a pipe with the main cylinder c. Ou the upper end of the plunger a is the carriage m,

that sets down into a recess in the deck or platform, so that the shot or charge can be rolled upon the said carriage, and then, by turning a cock, 7, the pressure raises up the charge, the same is stopped at the muzzle of the gun by closing the cock 7, and then the charge is rolled or forced into the cannon and the hydraulic carriage m lowered by opening the cock 8.

This apparatus for operating ordnance is not adapted to use with steam or vapor, and any such elastic or compressible substance cannot be employed advantageously for said purpose, because it is necessary that the gun remain very firmly in place while being fired, and not be subject to vibration or change of position resulting from adjacent explosions or the condensation of vapors, for which reason the steam cylinders heretofore proposed are not fully available, while with my invention, the operative force being a pressure from water, oil, or other practically non-compressible liquid, the gun-carriage and parts tilled by such liquid are, for all practical purposes, as rigid as it' made entirely of metal, and the gun is perfectly under control of a much less number ot' men than heretofore, hydraulic pressure, directed with great facility, being substituted for manual labor.

I do not claim, broadly, sustaining the weight of a gun or gun and carriage upon a hydraulic rain; neither do I claim a spring' or recoil shield, nor operating the gun by steam or vapor pressure.

What I claim, and desire lo secure by Letters Patent, is

l. The mode herein specified of elevatinga gun or mortar from behind a breastwork or protection previous to its discharge, and the lowering of the same .previous to loading, by a hydraulic rain and cylinder, as specified.

2. A hydraulic recoil-check consisting of a plunger acting against liquid in a chamber, from which chamber there is an opening or escape, substantially as specified.

3. Projecting the gun forward by the pressure ot a liquid upon a ram or plunger, substantially as specified.

4:. Adjusting or sighting a gun by means ot' hydraulic pressure acting upon a ram or plunger in a chamber, substantially as specifled.

5. Elcvating the charge or projectile by a ram or plunger acted on by hydraulic pressure, substantially as specitied.

6. Gonnectin g the chamber in which the recoil-plunger acts with the hydraulic cylinder, substantially as specified, so that the pressure ot' liquid in the latter shall force'the gun forward, as set forth.

In witness whereof I have hereunto set my signature this 24th day of June, A. D. 1865.

CHARLES PERLEY.
