SPECIFICATION forming part ofA Letters Patent No. 679,1 13, dated J'ulyi23, 1901. 4

Application led December 9, 1899. Renewed February 12, 1901. Serial No. 47,048. (No model.)

To all whom it may concern.-

Be it known that I, LOUIS L. Darcos, a citizen of the United States,residing at New York, in theborongh of Manhattan and State of New York, have-invented certain new and useful Improvements in Mounts for Field Artillery; and I do hereby declare the following to be a full, clear,'and exactdescription of the invention, such as will enable others skilled in the xo art to which it appertains to make and use the same.

My invention relates to improvements in recoil-mounts for eld artillery; and it consists in the 'certain improved means by which r 5 the shock of the recoil is taken up without substantial motion rearward of the carriage,

l in which the gun may be accurately trained through a small angle without disturbing the trail, and an improved means for braking the zo wheels of the carriage, and in certain other novel features and` details of construction that will be hereinafter more fully described and claimed.

Reference is had to the accom panyingdrawz 5 ings, in which the same parts are indicated by the same letters throughout the several views.

Figure 1 is a side elevation ofthe gunand mount, the axle being shown in section inside of the right wheel and other parts being shown 3o in section along the broken line l 1 of Fig.

10. Fig. 2 is a detail view showing the rear end of the trail. Fig. 3 is a view of the gun and the parts of the mount immediately adjacent thereto as seen from the rear. Fig. 4

3 5 represents a'section through the axle and the frontend of one of the cheek-pieces of the trail, the said section being along the line 4 4 of Fig. 10. Fig. 5 represents a view of the same parts, but along the line 5 5 of Fig. 10.

v4o Fig. 6 is a plan view of the gun and slide therefor as removed from the mount. Fig. 7 represents a vvertical section along the line 7 7 of Fig. 6, the gun being shown in elevation. Fig. 8 is an end view of a band to be Y 45 secured on the gun, vwhose function will be line 10 lO of Fig. 3. Fig. 11 is a det-ail view showing one of the hubs for the wheels with the brake attached thereto. Fig. 12 repre.- sents a section along the line 12 13 in Fig. 1l 55 and shows the brake in the inoperative position; and Fig. 13 represents a like section of the brake, showing the pin removed and the brake in operation. Fig. 14 represents a section along the line 14 14 of Figs. l2 and 13. 6o Fig. 15 represents the two brake-shoes detached from the brake in elevation, and Fig.

16 represents end views offthe same.

A represents the gun-body, which is provided with the front band A and the rear band A2. These bands have guide-lugs a.' and j a2, respectively, which travel in the guideways b in the top and bottom of the guideframe. This guide-frame consists of two parts B and B', hinged together, as -at b', so 7o as to inclose the gun-body, and the latter recoils in this frame. This lower member B of the guide-frame is provided with a perforated lug B0, in which the bolt C is mounted. This bolt passes-.through the two side brack- 7 5 ets D of the upper carriage, on which the gun is supported. These brackets `ID are joined together in the shoe-piece d, 'which is pivoted at d on the transom f, spanning the cheek-pieces F of the trail proper. The front 8o end of these side brackets D of the uppercarriage terminatesy in a yoke D2, projecting above and below the axle G, as shown in Figs.

5 and 6. The axle is preferably attened top and bottom, and eac'h yoke D'a is preferably 85 provided with one or more antifriction-rollers, which travel on top of the axle G. The yoke may be lined with a wear-plate do, if desired.

In order to prevent lost motion, I preferably 9o provide an adjusting-screw D4, which may be locked in place by a lock-screw d4, (see Fig.

5,) if desired. These screws D4 should be screwed np enough to be just clear of the bottom of the axle, but without binding thereon. The upper carriage,with the gun-mount thereon, is given lateral train through a small angle by means of the hand-wheel K, jour-v naled in the collar 7a', which is pivoted to the lug f at one side of the trail and which roroo tates a screw K', which has its screw-threaded portion 7c project into the elongated nut 7a2,

' in trunnion-lugs h, which project into the ver`v 'Moreoven vthis gives not only a'lateral train of the gun on the axle, but also enables nice adjustment to be quickly had', which is very difficult, where,as is now commonly the case, it is necessary to pick upthe spade out of the earth and train the gun by moving the trail.

The shock of the recoil of the gun on the mount is taken up as follows: H represents two recoil-levers pivotedon the bolt C and together forming va. yoke which projects up on either side of the gun. These two levers terminate tical guideway between-the lugs a2 ou the ring A?, made fast to the gun. (See Figs. 1, 6, and 7.) The lower end of each of these two levers is pivoted to a cross-headon the pistonrod E' of the recoil-cylinder E. This recoilcylinder is preferably provided with a spring strong enough to return thel parts tothe initial position shown -in Fig. 1 after the gun has been fired.' This recoil-cylinderEis pivoted, as at e, to the shoe-piecedv of theupper carriage, and the cylinder has a limited rotation in the vertical plane about its pivot. Pivoted on the bolt() is the elevating-bar P', connected, by means of the link Q and pin q, to the'lugs B4 at voneside of the lower mem'- ber of the guide-frame B. To the rear end of this bar P' 'the collar P is pivoted, through which passes the screw N, which screw engages the nut D', pivoted to one of the side brackets of the upper carriage. This screwis turned by means of the hand-wheel N'.- r.lhus the gun is elevated or depressed by screwing up or down on this screw N. When the gun isiired, it recoils tothe rear in the guide-frame, the trunnion-lngs h passing up in the guideway between the lugs a2, which thus allows for the vertical play of the said lugs, while at the same time the upper ends of the levers H are drawn rearward, dragging out the piston-rodE against the action of the -spring in the cylinder E and checking the recoil of the gun. After the gun has recoiled the spring in the recoil-cylinder restores the gunto the initial position. The rear end of the trail is provided with a spade F', braced by the supporting-plates f' and f2, (see Fig. 1,) and the shoe of the trail is provided with the usual socketf3 for the ytrail hand-spike F3. '.Io brake the wheels AW of the mount when the gun recoils', I provide the mechanism shown in Figs. to 16, where each Wheel W is provided with a hub W', having flanges w for the spokes of the wheel. The spokes arev omitted in Fig. 11, and to th-is'hub is rigthe engaging arms of the brake-shoes X and X', which brake-shoes have the curved members m shouldered, as at w3, on the inside and terminating in oppositely-disposed arms fc', each `provided with a hole .ft2 for the ta pered pin Y, which pin is preferably held by means of the chain 'y to the axle. -These brake-shoes are assembled as shown in Figs. When the pin Y is inserted in the place, as shown in Fig. 14, which would be the normal position except when in battery, the brakeshoes do not engage the wearplate to2, and consequently there is no tendency of the wheels to brake. If, however, the pin be removed and thev piece be dragged either by the recoil or by hand, causing the hub to vturn in the direction of the'arrow in Fig-13, each brake-shoe Will-pivot about the shoulder m3. The brake-shoe X will bind at .1:4 against the wear-plate '102, and the tendency'- 4will be to bind more and more, while the brake-shoe. X' will bind about the points x5,

and the tendency will be for each to bind more and more as the motion of the wheel continues in the same direction. Moreover, it will be obvious thatif the brakes'are'a snug fit the least `motion of the Wheel rearward will throw the brakes into engagement. Thus it will be seen that the brakes operate automatically and with great holding power.

From the Aforegoing it will be seen that I provide a field-carriage which consists, Aessentially, of two parts, an upper carriage, in which the gun is mounted and which may be trained laterally without disturbing the trail porting this upper carriage and performing the ordinary functions of -a `field-carriage,

IOO

.of the lower carriage, the lower carriage supmechanism for controlling the recoil of the gun and for restoring the gun to the initial position, readily accessible mechanism for elevating and training the gun with great'exactitude, and mechanism for promptly and etnciently braking the wheels.

vIt will be obvious that one brake-shoe only-as, for instance, the brake-shoe X- may be used, if'desired. l
