Application filed January 25, 1901. Renewed September-J1, 190 1. Serial No. 76.089. (No model.)

To all whom it may concern:

Be it known that I, GEORGE SYDENHAM CLARKE, residing at London, England, have invented certain new and useful Improvements in Field-Guu Carriages, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to carriages for fieldguns. c

The object of the invention is to provide a field-gun carriage with an anchor or spade to resist recoil, which spade shall permit a free traverse or swing ofthe gun-carriage without detachment and'which will permit recoil and return the carriage to firing position after recoil.

Figure 1 is a section of a gun-carriage with anchor mechanism attached and shown'in eleverfo'r holding up spade.

ration, some other parts being also shown in elevation. Fig. 2 is a section of carriage and anchor mechanism. Fig. 3 is an elevation of spade and cylinders detached. Fig. 4 is a detail section of sleeve and elevation of le- Fig.'5.is a broken section showing connection of lever to trail.

The numeral 1 indicates the axle of a gun carriage, 2 a wheel, and 3 the trail of a fieldgun carriage, which maybe of anyusual construction. -As shown, the trail is a metallic shell. A bracket 4 is forged or otherwise rigidly connected to the axle at the center thereof and directly under the gun, and to this bracket a hollow cylinder 5 is connected by a pivot, the bracket and the end of the cylinder thus being connected, so that the cylinder 5 may swing as a pendulum lengthwise of with a force just less'than enough to sustain such weight.

the gun. A second andjsmallercylinder 6 telescopes within the cylinder 5, being-free both to turn and slide therein, but being prevented from withdrawal by any suitable mechanism, as by the attachment of the spring 7 to both sections of the cylinder.

coiled spring 7 within the two cylinders tends to project the smaller cylinder. The strength of this spring is sustain the weight of the gun and carriage, but will press the smaller cylinder outward The smaller cylinder 6 has a broad spade S attached thereto -and preferably provided witha serrated end.

The

and by the cable the recoil has exhausted itself such that it will not quite rent without removing length of the cylinders is such as to force the spade well into the ground whenthe axle is directly over the spade and to secure a good engagement of the spade when the gun is forward, as in Figs. land 2. The cylinder5 has otherwise attached. The trail has a sleeve-or bar 10, extending crosswise and provided with a hook 11, which may engage book 9 on the a hook or socket 9.,connected to'a ring or cylinder when the said cylinder is swung up against the trail, (dotted lines, Fig. 1,) and this sleeve or bar may be rocked by lever 12, so as to bring hook 11 into engagement with hook 9 and hold the cylinder and spade in upward position. Lever 12 may be held against the trail by a pin 13, passing through a hole in the lever and into a hole in the trail, or I other means for holding the lever in locked positioumay be employed. The spade or its handle, which is cylinder 6, is connected to a strong spring l5'by a cable or cables 16, at-

tached-to the spade and to the spring or to a the spring. A casing 19,

guide-rod 18 within incloses the spring firmly secured to the trail, 15, and the spring bears said cylinder when compressed.

Any of the usual mechanisms-for regulating the tension of the springs may be employed, such mechanism being common in several of theanechanic arts.

The'gun being in firing position, as in Fig. 1, will on firingibe driven back by the recoil, forcing the spade more firmly into the ground 16 compressing the spring 15. As soon as (and the usual wheel-brakes may assist in checking the recoil) the spring 15, drawing on the cable 16 and spade 8, forces the gun and carriage forward, and so the gun is autoagainst the end of matically returned to firing position after each discharge.

As the spade handle or cylinder 6 is free to turn in the cylinder 5, the carriage may be swung about the spade to a considerable ex-' the spade from the. ground. This is an important advantage over usual constructions.

. The drawings do not purport to give exact constructions and proportions, but only the essential elements,'which are in actual con struction varied according to the gun-carriage construction andthe requirements of usage. The claims indicate the scope otjwhat I be lieve my invention to embrace.
