P TENT ARTHUR TREVOR DAWSON AND GEORGE THOMAS BUCKI-IAM, OIF WESTMINSTER,
LONDON, ENGLAND, ASSIGNORS TO VICKERS LIMITED, OF WESTMINSTER, LON- DON, ENGLAND.
ORDNANCE.
To all whom t may concern:
Be it known that we, Sir ARTHUR TnEvoR DAWSON, knight, and Sir GEORGE THOMAS BUOKHAM, knight, both subjects of the King of Great Britain, residing at Vickers House, Broadway, Westmister, in the county of London, England, have invented certain newv and useful Improvements in or Belating to Ordnance, of which the following is a specification.
This invention relates to ordnance provided with vertical deflection gear for adding Or subtracting the vertical deflection angle to or from the angle of tangent elevation for a target advancing toward or receding from the gun position; the invention is particularly applicable to such guns having an independent line of sight.
According to the invention we provide means whereby the operation of the vertical deflection gear causes the reading of the tangent elevation or range indicator operated by the tangent elevation or ranging gear which effects relative movement between the gun and the sight, to be varied by an amount proportionate to the amount of the vertical deflection it is required to impart so that the act of operating the tangent elevation or ranging gear vuntil the reading of the indicator is the same as it was prior to the operation of the vertical deflection gear, imparts the required vertical deflection. For this purpose the vertical deflection gear and the tangent elevation or ranging gear may operate upon the usual tangent elevation dial through a differential gear so that the dial can be operated either simultaneously or independently by the said gears.
In order that the said invention may be clearly understood and readily carried into effect, we will describe the same more fully with reference to the accompanying drawings, in which Figure 1 is a perspective view showing diagrammatically a gun carriage for a gun having an independent line of sight, provided with a form of our improvements.
Fig. 2 is a vertical transverse section showing a constructional form of the improvements illustrated diagrammatically in Fig. 3 is an elevation showing a slightly modified arrangement of the tangent elevation dial and the differential gear through Specification of Letters Patent.
Patented Jan. 4, 1921.
Serial No. 345,907.
whichthis dial is operated by the vertical deflection gear and the tangent elevation gear,
Fig. 4 is a section taken approximately on the line 4-4 of Fig. 3, and
Figs. 5 and 6 are respectively a side elevation and a plan showing diagramamtically the invention employed in conjunction with a' gun not having an independent line of sight.
In Figs. 1 to 4 A is the tangent elevation dial and A is the zero Or index mark against which the graduatioiis on the dial are read. B is a shaft operated by the tangentelevation hand wheel B through the gearing shown by Fig. 2, this gearing comprising a worin driven from the handwheel B through gear wheels which are not shown, a worm wheel b a bevel wheel bx and a bevel pinion bx. C is a shaft operated by the hand-wheel C of the vertical deflection gear (Fig. 2) which is situated at the right hand side of the carriage. These shafts B and C operate upon the dial through the differential gear D which is associated with the said shafts and with the dial A either in the manner shown by Fig. 2 or in that shown by Fig. 3. A spring E of the spiral or clock type is in Fig. 3 interposed between the casing D of the differential gear and the member D2 of this gear attached to the dial A, this spring tending to move the dial constantly in one direction for the purpose of eliminating backlash in the geared members of the differential gear.
The pointing crankhandle F of the gun is geared direct to the sight bracket through the shafts e c', and interposed bevel pinions, and a worm on the shaft e gearing with the sight elevating rack e2 as shown by Fig. 1. An extension eX (Fig. 2) of the shaft e carries a worm meshing with a worm wheel E and between this worm wheel and the aforesaid worm wheel Zi is a differential gear which is associated as shown by Fig. 2 with a shaft F carrying a pinion F gearing with the elevating rack F2 (Fig. 1). Thus the pointing gear elevates the gun and the sight together while the tangent elevation gear elevates the gun alone by the amount of tangent elevation plus the vertical deflection.
In Figs. 5 and 6 which show the invention employed in conjunction with a gun not having an independent line of sight, G is the sight bracket and G the toothed arc thereon with which meshes a pinion g. G2 is the hand wheel which adjusts the sight for range and which operates the pinion g through a differential gear similar to that shown by Figs. 3 and 4; this differential gear is also operated upon by the vertical deflection hand-wheel C and is associated with the range dial A in substantially the manner described with reference to Figs. 3 and l. Thus when the vertical deflection hand-wheel C is operated, the reading of the dial A against the Zero mark A is varied by an amount proportionate to the amount of vertical deflection it is desired to impart, with the result that the actuation of the hand-wheel G2 to cause the reading to be the same as it was previously7 imparts the required vertical deflection to the sight bracket G.
What we claim and desire to secure by Letters Patent of the United States is l. In ordnance, the combination with the sight of means for effecting relative movement between the gun and the sight to 1m,- part the required angle of tangent elevation, an indicator operated by said means, vertical deflection gear and means whereby the operation of the vertical deflection gear causes the reading of the said indicator to be varied so that the act of operating the first mentioned means until the reading of the indicator is the same as it was prior to the operation of the vertical deflection gear, imparts the required vertical deflection.
2. In ordnance, the combination with the sight, of means for effecting relative movement between the gun and the sight to impart the required angle of tangent elevation, an indicator operated by said means, vertical deflection gear and differential gear through which said means and said vertical deflection gear operate upon the indicator.
3. In ordnance having an independent line of sight, the combination with the sight, of pointing gear for elevating the gun and the sight together, ranging gear for moving the gun relatively to the sight to give the re quired angle of tangent elevation, an indicator operated by the ranging gear, vertical deflection gear and means whereby the 0peration of the vertical deflection gear causes the reading of the said indicator to be varied so that the act of operating the ranging gear until the reading of the indicator is the same as it was prior to the operation of the vertical deflection gear, imparts the required vertical deflection.
4. In ordnance having an independent line of sight, the combination with the sight, of pointing gear for elevating the gun and the sight together, ranging gear for moving the gun relatively to the sight to give the required angle of tangent, differential gear through which the pointing gear and the ranging gear operate upon the gun, an indicator operated by the ranging gear, vertical deflection gear and differential gear through which said ranging gear and said vertical deflection gear operate upon the indicator.
5. In ordnance, the combination with the sight, of sight elevating gear for moving the sight relatively to the gun to give the required angle of tangent elevation, an indicator operated by this gear, vertical deflection gear and means whereby the operation of the vertical deflection gear causes the reading of the said indicator to be varied so that the act of operating the sight elevating gear until the reading of the indicator is the same as it was prior to the operation of the vertical deflection gear, imparts the required vertical deflection.
6. In ordnance the combination with the sight, of sight elevating gear for moving the sight relatively to the gun to give the required angle of tangent elevation, an indicator associated with said sight elevating gear, vertical deflection gear which is associated with said indicator, and differential gear through which said sight elevating gear and said vertical deflection gear operate upon the indicator.
In testimony whereof we afliX our signatures.
