GUN MOUNTING OR CARRIAGE.

S PECIFICATION forming part Of Letters Patent NO. 729,342, dated May 26, 1903. Application filed July 28. 1902. Serial No. 117,404. (No model T all whom it inmy concern.-

-Be it known that we, CARL I-IOLMSTROM and AXEL BREMBERG, engineers, subjects of the King of Sweden and Norway, residing at Parkhead Forge, Rolling Mills, and Steel W'orks, Glasgow, Scotland, have invented certain new and useful Improvements in Gun Mountings or Carriages, of which the following is a specification.

no This invention relates particularly to field-- gun carriages or mountings.

According'to our invention thegun is arranged to recoil axially in a cradle, which is provided with a hydraulic buffer or recoil s 5 cylinder situated, preferably, above the gun, although said buffer may in some cases be situated at one side of or below said gun. The said buffer is provided with longitudinal guides for-the reception of a corresponding :0 lug or lugs or bracket or brackets on the gun:

These guides are located in a position to be protected from subject in traveling or while in action. In

' order to protect the buffer, it may be provided with a casing of nickel-steel or other suitable material. The cross-head in which the eradle trunnionbeari'ngs are formed is adapted to slide upon an axle-bracket about a vertical or approximately vertical'pivot on a transom-' 3o bracket in the trail. The elevating-gear is so arranged that the gun and sighting apparatus can either be moved together in the ordinary way or the gun can be elevated or depressed to accurately alter the range with- 3 5 out altering the line of sight. The said elevating-gear is connected to and moves laterally with the cross-head. The sight-bar, carried by the elevating-arm,'slides in guides around the trunnions when the sight is raised 40 or.lowered and a pointer fixed to the cradle shows the range on the graduated stem of the rear sight. i

In order that our said invention may be clearly understood and readily carried into practice, we will now describe the same with reference to the accompanying drawings, in which- Figure 1 is a side elevation of the gun and its carriage with one of the carriage-wheels 5o. removed. Fig. 2 is a plan of the said gun and carriage. Fig.3 is a'transverse section blows to which the gun is taken approximately on the line 1 1 of Fi showing the arrangement of the brake o coil cylinder relatively to the gun and the tect-ive casing for said cylinder. Fig. 4 sectional elevation showing, ona larger s the elevatingand traversing gear. Fig. a vertical section on the line '2 2 of Fi showing the elevating-gear.

A is the gun.

B is the buffer or recoil cylinder.

0 is the carriage-wheel axle, andC C the carriage-wheels.

D is the cross-head, carrying the c1 trunnion-bearings.

E is the cradle, and E E trunnions.

F is the axle-bracket, on which the c head traverses or slides.-

G is a hand-wheel for actuating the tra ing gear.

H is the elevating-arm.-

I is the sight-bar.

J is a hand-wheel for operating the gm sighting apparatus simultaneously.

K is a hand-wheel for operating the independently of the sighting apparatu The aforesaid buffer or recoil cylinder I longitudinal guides Z) b, Fig. l, on its r side, and the gun has on its upper side the muzzle a T-shaped lug or bracket a, v engages with and slides in the said longi nal guides on the recoil-cylinder.

b is the casing forprotecting the butfe inder and guides against rifle-fire and: ters, said casing being made of harc nickel-steel or other suitable metal. "lh casing is preferably situated a short dis from the buffer-cylinder, as represent Fig. 4, so as to leave space for possible i: tation of the casing without damage i buffer-cylinder. The casing is secur place on the buffer-cylinder by mea' screw-boltsb or other suitable faste1 The space b Fig. 1, existing betwee gun and the buffer-cylinder may be co are the er in any appropriate manner to avoid t] trance of dirt or other foreign matte] would interfere with the proper move: of the lug or bracket a in its guides b the gun reciprocates. The buffer-cylir preferably formed of steel and forged i e with the cradle. By making the aforeguides on the buffer-cylinder and the :ket on the gun we are able tovproyide any desired length of recoil movement of gun by increasing the. length ot the butterndcr. 7 he aforesaid cross-head l) is formed at its with an eye or socket (I, which fits the or end of a bolt d, that passes vertically ugh bearingsk/ 11*, carried by the tran- -bracket (1, the said bolt occupying a pom in proximity to the screw of tin-elevatgear. The said cross-head has grooved gcs or clip-pieces 11' 1/ to engage with le-pieces ff on the axle-bracket i The grooved flange (1" is composed of a bar .red to the under side of the cross-head by w-bolts (1, so as to permit of the cross- 1 being conveniently attached to or reed from the axle-bracket. The guideesff are arcs of circles concentric wit h center of the pivot-bolt 1/, so that the s-hea'd can freely turn about the axis of bolt to tra'verse, the gun and cradle. Inr to actuate said cross-head, it is provided a segmental rack (1 riveted'or otherwise red to the under side oi? the crossdiead. teeth of the rack gear with a worm-spinwhich is mounted horizontally in bearf' on the axlebracket and which is )ted to be revolved by the lntnd-wheel G, uted on an axle g, having a worm g, gearwith a worm-wheel on the spindle d. aforesaid pivot-bolt (1 also carries a et 1]", which at its upper part is formed to ivc trunnions j j, provided on a cylinll casingjfl which has curved guide-pieces tuated near its lower end and arranged entrie with the said trunnionsj, these e-picces being adapted to bear against nu lcr side of correspondingly-curved sur- 4 d'" oi. the socket (1. is a bevel-pinion having an extension'j", tits into the aforesaid casing], so as to therein without moving longitudinally respect thereto, for. which purpose it has vwer port ion provided with a screw-nutj". interior of said extension is formed with vvthreads and constitutes a nut that ;s in conjunction with a screw j. This iv j" is made hollow and is internally ,v-t breaded to receive asccond or smaller ,vj', which is pivotally connected at 71 to devating-arm ll. The two screwsj and {other form a telescopic screw device for ating the said'elewiting-arm. (learing' the bevel-pinion j is a bevei-whccl j, h is fixed on a hollow shat't j, carrying land-wheel J. The two screws j and j the same pitch, and both of them may ther left-handed or right-lunulcd, The r screw f has a stop f at its lower end, the inner threads of the screw j have a ji These stops when they meet to- }r limit the movement of the two screws ively to each-other, so that they cannot igworkingbecomedetached. 'lheouter screw 3' has a stop j, and the threads in the bevelavheel j have a stop j. These stops when theymeet together limit the movement of the serewj relatively to the bevel-wheel, so that said screwij" cannot screw out of the said. bevel-wheel. \Vhen the wheel j is revolved, the screw j can either fully or partly participate in the revolution of the wheel-j or can remain stationary, there being only slight friction between them; but in any case same amount when the wheel j is revolved in either direction. The aforesaid elevatingarm II has a socket or guide /1' to receive the arc-shaped member 1' ol the sight-bar l. The curvature of this arc-shaped member is concentric with the gun-trunnions, and the forward portion of said sight-bar is curved at 1" to engage with a correspomlingly curved socket or guide c on the cradle ll. the curvature of said guide and curved portion being concentric with the gun-trunn ions. The aforcsaid trunnionsj permit thc elevatilug-gearing to move freely in a vertical plane, and the connection oi the socket rl to the pivot-bolt (1 permits said gearing to move freely horizontally with the gun and cradle and the cross-head when the training is being et'- fected. A pointer c is provided on the cradle adjacentto the said curved portion 1' of the sight-bar for indicating the range. The said sight-bar is furnished with a rear sight {2 and a fore sight '2'" and is capable of being actuated independently of the elevat ing-ar'm II by a pinion having an operating-handle 1" and engaging with teeth on the said areshaped member 1:; The rear end of the said elevating-arm II 'is socketed to receive a screw-nut 7;, having trunnions 79' to engage with recessed hearings on the lower portion of said socketed portion. The said nut is formed with curved cheeks If at its upper portion to engage with corrcspondinglya-urvcd portions 71 on the arm II, the said curved portions being concentric with the trunnions It. Fit-tin g the said not I; is a screw 1;, which is pivot-ally connected at 7. to the gun-cradle. This screw k has a worm-wheel 75", which gears with a worm mounted on the spindle 7;, that carries the hal'ul-wheel K.

\Vhen it is desired tot'raverse the gun, the hand-wheel Gris operated, whereby, through the aforesaid gearing (Z (1*, the gun will be shifted to the right or the leftin acorn-dance with the direction in which said hand-wheel is turned, the said cross-head l) movin bodily on theaxle-bracket 1" about the axis of IIO the pivot-bolt (l and carrying with it the gun, the cradle, the sighting apparatus, and the elevating-gear, while the trail and carriagewheels remain stationary. hen the gun and sighting apparatus are to be operated simultaneously, the hand-wheel J is actuated in the required direction to elevate or depress the gun, whereby the screws j j are actuated as aforesaid and the elevating-arm l-l raised or lowered together with the sight-bar and the gearing is 7:3, which latter moves vertically without revolving. If, however, the elevation of the gun is to be changed without altering the line of sight, the hand-wheel K is operated in the required direction, whereby the gun is elevated or depressedwithout affecting the gearing J and without actuating the elevating-arm ll or the sight-bar I.
