To all whont it WI/(11y concern:

,Be it known that I, LOUIS LABADIE D uecs, a citizen of the United States, residing at Washington, District of Columbia, have in vented certain new and useful Improvements in Gun-Mounts; and I do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to improvements in gun-mounts, and it is more especially intended to provide means whereby the gun may be quicklyv and accurately pointed.

The improved means for pointing the gun comprises mechanism for adjusting the gun in elevation while the line of sight iskept on the target, thus regulating the adjustment between the line of sight and the line of fire without taking the sight or sights off the target, and also in improved means whereby the un may be trained either from the shoulderbar or by power-gearing, as may be desired.

My invention also consists in certain novel constructions, combinations, and arrangements of parts, as will be hereinafter more fully described and claimed.

Reference is had to the accompanying drawings, in which the same parts are indicated by the same letters throughout the several views. I

Figure 1 shows a side elevation of the gun and mount and shows the elevatinggear and sighting-arm with connected parts. Fig. 2 is a plan view of the gun and mount.

Figs. 4 and 5 are detail views showing thetraining-gear on a larger scale, Fig. 5 being a section on the line 5 5 of Fig. 4 and looking down. Fig. 6 is a detail view, on a smaller scale, taken along the line 6 6 of Fig. 5 and looking in the direction of the arrows. Fig. 7 is a detail view showing parts of the elevating-gear and the sighting mechanism on an enlarged scale; and Fig.8 represents a section of the parts mounted on the main elevating-shaft, the said section being along the line 8 8 of Fig. 7 and looking in the direction of the arrows.

A represents the gun, which is mounted to recoil in the rocking slide B against the resistance of the recoil-cylinders B. This slide Fig. 3 is riage C, which top carriage is turned on the bottom carriage C" in training the gun. The top carriage has a rearwardlyprojecting Web C", carrying the brackets C and G I D represents the sighting-arm, which is pivoted on one of the trunnions B and is curved upward to carry a suitable sight:- such, for instance, as the telescope D. This sighting-arm is provided with an index (1", which points to a graduated scale b on the web B which projects rearward from'the slide 13. This web also carries a curved rack 12. (See Figs. 1 and 7.) The sightin-armD has a downwardly-projecting curve rack cl secured thereto, which rack meshes in the pinion c on the shaft E, which shaft carries a worm-gear E, which meshes with the Worm F, fast on the shaft F. This shaft F has loosely mounted thereon the sleeve F carrying at one end the hand-Wheel F for turning said sleeve and provided at the other end with an annular rib f to en age the clutch member F which is normally pressed into engagement with the clutch member F' 'by means of the spring F The clutch member F is fast to the sleeve F and the clutch member F is fast to the shaft F, the shaft being journaled in the bracket C and the sleeve F being journaled in the bracket C The end of the shaft F is provided with a head f to limit the longitudinal motion of the sleeve thereon, and suitable antifrictionbearings f are provided Where desired. It will be seen from an inspection of Fi 8 that the spring F will normally tend to old the clutch members F and F in frictional engagement, in which case if the hand-wheel F be turned both the sleeve F and the shaft F will be turned with it, while if the hand-wheel be drawn out slightly against the action of the spring F releasing the frictional engagement of the clutch members F and F", the

sleeve F may'be turned freely on the shaft F without turning said shaft.

Splined on the sleeve F? is a worm F7, which meshes in the worm-gear H on the shaft H, journaled in the bracket 0 which shaft carries on its inner end the gear-Wheel Hiwhich meshes with the curved rack b, fast to the vertical web B which is secured to or integral with the slide B. Thus'it will be seen the t if the henzhwheel F" be turned the gear- Whcel 5" will cause the reek turning-of the hend-wheel F will merely elevote and depress the gun without i-lfecting the position of the sighting-arm; hut when these clutch members are in engagement turning the hand-wheel F" will not only elevate or depress the gun, hut will also impart a. corresponding motion to the sighting-arm D by means ol. its rack (Z and the gearing connecting said ruck with the shaft F.

In practice the sight is first brought to bear on the target irrespective of the elevation at which the gun is to he fired. Then keeping the sight on the target, the hand-Wheel F" is drawn back, releasing the clutch Inemhers F and F and the gun is elevated or depressed until the pointer d" on the sightingerin points to the proper elevation on the scale t (See Fig. 1.) Now if the sight is still on the target the gun will he properly pointed. Now the hand-wheel released and the sleeve F is allowed to press l'orvmrd under the action .of the spring 5", causing the clutch members F end F to engage, and both gun and s1ght= may he rocked in unison about the trunnions B by turnii'ig the linnd-wl1e0l F The worms and gear for operating the two racks b and (Z are preferably so proportioned that both the sleeve and sighting-emu. will he rocked through an equal angle, no matter What may he the motion of the luuuhwheel F, and thus the relative bearing between the line of sight and the line of lire will be maintained constant, except, oi course, for the slight difference due to setting the sight at en angle to compensate for dril't, &c. This, however, is a feature Well known'in the art and need not he further considered in this specification.

Thus it will he seen that I pro ide means h Y hich the. desired angle between the line of sight end line oi lire inaybequiuhly and seourntel v arrived at without requiring ill? gun-pointer to hike his sight oi? oi the target, and as the gun is further elevated or dopressed incident to pointing this angle between the line of sight and the line ol lire will he maintained. This is oi special importance in the l in the method of sighting guns now most commonly in use when it desired to change the ole .ition ol' the gun it is the practice to reset the rear sight and then to try to find the target by elevating or depressing the gun; but will] the lieroin-doscrihed mechanism the sight is first brought on the target and then is kept there while the line of lire of the gun is brought into proper relation. with the line of sight. In [his wily no time is lost in picking up the target and greater rapidity and accuracy of lire urcolituinzthie.

F r convenience in operating the gun the l gun-winter is provided with e shoulder-rest I, z nched to the verticully-edjustehle her i, which is clamped at the desired height in the socket I by nieansof the clamp This socket I is detechuhly connected to ,the arm C", secured to the top carriage C.

The herein-described device for elevating and depressing the gun is intended to operate in training from the shoulder independently of or in connection with the traininggear that will now be described.

T he training-gear proper is preferably on the opposite side of the gun from the shoulderdmr and elevating-gear and is operated by another member of the guns crew, under the direction, of course, of the gun-pointer.

K represents a pinion meshing in a circuler reek C (see Fig. 8 and in dotted lines in Fig. 2,) his: on the lower carriage C. This pinion is last on the shaft K, journuled in the )racket fast to the upper carriage C. This shaft K has n worm-gem if? loosely mounted on the some near its upncr end, which gear is caused to turn no mal with said.

shaft 0} means oi tlzv 'irietio'wd 1'5 (See Fig. 4.) The purpose of t icl'ionul engegeinent is to prevent the sripping of teeth or injurx to other parts of the training-gear when excessive st sins are imposed thereon. This wornrgeur it! meshes with the worm hi on the shaft M, whioh shaft Curries the bevelgear M", meshing with the pinion N on the shaft N, which shuit carries the hand-Wheel N and is journeled in lhe sleeve N, carrying the hand-wheel N This sleeve is provided with El limited number of screw-threads n", which engage in u screw-threaded collar c, carried by the urn] C, last to the upper our rings (1. By huvin these scrmv-threads n not extending the Hill length of the screwtlirends in the roller the sleeve may be moved longitudinnil through a limited disiztllCO only; but it will be obvious that the tin-ends o. boil: sleeve and collar mi ht he continuous. ii desired. The sleeve N 1 provided with EU! annular groove n, into which project the points oi' the serous p, carried by the l)l()(,'l( l, in which block the shaft M is journuled. 'lhis hlorl; is provided with n guidvwziy 1/ (see Fig. (5) lo engage the flanges 0 so that the shalt 3i", :md with it the worm Rhinuy be moved toward or away lroin the wornugeur li' when desired. Thus when ll!- sirod the num all the {ruining-grin" by turning the hand-wheel N may throw the worm into or out of engagement. with the worm gear ii Vv hon it is de ired lo train flu un quickly, :1 quick inol ion of the hund-wlwel hi by mechanical means only independent oi" the slioulder-har; but this bar may he used will cause the worm M lo be drawn out of en- I the hand-Wheel N is turned in the reverse direction, causing the block P to move toward the shaft K, which will cause the worm M to engage .with the gear K at which time the training of the gun may be etlected by means of the hand-wheel N which will rotate the pinion N and will turn the bevel-gear M and the worm M, causing the latter to turn the pinion K, which will turn the upper carriage on the lower. Thus it will be seen that I have provided mechanism by means of which the gun may be roughly and quickly trained, as from the shoulder, while extremely accurate training is effected by suitable power mechanism, and that I have also provided mechanism by which the line of sight may be brought on the tar et and may be held there while the line of me of the gun is brought into its proper relation with the line ofsight.

It will be seen that the gun-pointer can hold one hand on the trigger-guard and with the other by manipulating the single Wheel F he is able to either change the angle between the line of fire and the line of sight or may swing both line of fire and line of sight simultaneously, as may be desired.

It will be evident that the sighting-arm'l) may be pivoted to any part of the top carriage, and the proportions of the same and the gearing for operating the same might be so al- 'tered to correspond to such change as to give the desired movement. This is a mechanical detail which may be worked by any one skilled in the art.

It will be obvious that various modifications might be made in the herein-described apparatus which could be used without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
