GUN-CARRIAGE.

Specification of Letters Patent.

Application filed April 8, 1916. Serial No. 89,903.

To all 'whom t may concern: n

Be it known that I, JOHN LUND, a citizen of the United States, and residing at Bethlehem, county of Northampton, State of Pennsylvania, have invented certain new and useful Improvements in Grun-Carriages, of which the following is a specification.

This invention relates to eld gun carriages and particularly to the type of such carriages in-which a pair of relatively movable trail members are used to afford lateral stability to the carriage. The object of the invention is to simplify the construction and connections of the trail members and render them more eflicient in withstanding the strains to which they are subjected. The invention will be described in connection with the accompanying drawings, in which,

Figure 1 is a plan view of a gun carriage embodying my invention;

Fig. 2 is an incomplete sectional view on the line 2 of Fig. 3;

Fig. 3 is a section on the line 3 of Fig, 1; and

Fig. 4 is a section on the line 4 of Fig. 3.

Referring to the drawings, 10 indicates the axle on which the wheels 11 rotate. Depending from the axle is a rectangular tongue or hanger 12 in which is pivotally mounted a guide frame or beam 13.l The tongue extends through rectangular openings 14, 15, in the beam and the beam is pivotally connected to it by the pin 16. The openings 14, 15, are large enough to permit lthe beam or guide 13 to have a limited rocking movement, as will be apparent from an inspection of Fig. 4. The beam 13 has a forward extension 17 to the forward end of which two trail members 18, 18, are pivotally connected. As shown, the forward ends of the trail members are sharply curved inward at 19 and hinged together and pivotally connected to the part 17 by means of a pin Q0. These trail members extend through a rectangular opening in the beam 13 and are free to slide therein laterally to bring the rear ends of the trail members together, as indicated in dotted lines in Figs. 1 and 2 or to spread them, as shown in full lines in said figures, for the purpose of giving the carriage lateral support when in operative position, especially when firing at an acute angle with the line of the axle.

In the drawings I have shown a base 21 pivotally mounted on the axle 10 and suitable -to receive the top-carriage of the gun. The base 21 is adjustably supported on and connected to the bracket 17 by means of a screw 22 which is threaded through a rotating block 23 mounted in trunnions in the forward end of the bracket 17 and in axial alinement with the pivot pin 16. This screw, as shown, may be connected with the course may turn in the wheels to permit the hanger 12 to accommodate itself to the position assumed by the trail members regardless of the inequalities of the ground. On account of the freedom of the beam 13 to swing and turn, the rear ends of the trail members are free to adapt themselves to any surface conditions and always free to plant themselves firmly in the ground.

When firing a gun mounted on the above described gun carriage the downward stresses due to recoil are transmitted directly to the axle and the wheels, while the upward stresses due to recoil are transmitted through the screw 22, described above, and to the forward end of the trail members 1,8. Due to the peculiar connection of the beam 13, each trail member will take an equal amount of the stresses, no matter what the position of the rear ends of these members relative to4 each other or relative to the lower elements of the wheels may be.

Having described the invention what is claimed is:

1. In a gun carriage, the combination with the axle, of two trail members extending forward of the axle and having their forward ends pivotally connected together, the pivotal axis being vertical, permitting the members to swing relatively in a substantially horizontal direction.

2. In a gun carriage, the combination with the axle, of two trail members extending forward of the axle and having their forward ends pivotally connected together, and a guide beam pivotally connected to the axle and through which said trail members ass.

p 3. In a gun carriage, the combination with the axle having a depending tongue, of a guide-frame -orbeam pivotally connected tosaid tongue and lying beneath the axle,

' trail members extending through said guide frame or'beam onv opposite sides of said tongue, said trail members having their forward ends'hinged together in rontofthe axle. v
