Application March 1, 1932, Serial No. 596,088

Claims.

(Granted under the act of March 3, 1883, as

amended April 30, 1928; 370 O. G. 157) The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

This invention relates to a gun carriage.

The purpose of the present invention is to provide a gun carriage wherein a trail mounted for traversing movement on a crank axle is connected thereto by a strong simple bracing means.

To these and other ends, the invention consists in the construction, arrangement and combination of elements described hereinafter and pointed out in the claims forming a part of this specification.

A practical embodiment of the invention is illustrated in the accompanying drawings, wherein:

Fig. 1 is a plan view of the gun carriage.

Fig. 2 is a view in side elevation with the rear Wheel removed.

Fig. 3 is a sectional view showing the traversing mechanism.

Fig. 4 is a view in rear elevation of one end of the axle.

Fig. 5 is a plan view in section of a portion of one of the depending crank arms, taken along line 5 of Figure 4.

Referring to the drawings by characters of reference, there is shown a gun carriage which is a modification of the existing 75 m/m gun carriage, 3 French type. The carriage consists generally of an axle 5 on which a trail 6 is mounted through a bearing '7 for sliding movement. The axle is provided with threads 8 engaged by a nut 9 that is retained laterally relative to the trail by means of thrust washers 10 and 11, the former seated on an internal shoulder 12 of the bearing and the latter seated on the inner end of one of the side brackets 13. By virtue of the lateral retention of the unit on the trail any rotation imparted to the nut will cause the trail to be moved across the axle. A gear wheel 14 on the nut is driven from actuating mechanism 15. All of the foregoing elements constitute the normal structure of the existing gun carriage and form no part of the present invention.

Instead of mounting the wheels 16 directly on the axle, they are of small diameter and are mounted on spindles 17 at the lower end of a depending crank arm 18. The arm includes a bearing 19 fitting on the spindled end of the axle and retained thereon by a plug 20 threaded internally to the axle.

A pair of braces 2121 connect the trail 6 and the depending arms 18. The braces are attached to opposite ends of a cross-rod 22 fast on the trail and to a U-bolt 23 secured to each arm 18 on the axis of the spindles 17. When the trail is traversed across the axle the rear attachment of the braces will be moved laterally. Because of the rigidity of the braces their forward attachment to the arms 13 undergoes a displacement and causes the arms to rotate slightly on their bearings.

I claim.

1. In a gun carriage, an axle, crank arms rotatably mounted on the ends of the axle and depending therefrom, a spindle on each arm, a wheel on each spindle, a trail mounted on the axle for traversing movement, and a rigid brace connecting the trail and each crank arm, the attachment to the crank arm being in the plane of the spindle.

2. In a gun carriage, an axle, crank arms rotatably mounted on the ends of the axle and depending therefrom, a spindle on each arm, a wheel on each spindle, a trail mounted on the axle for traversing movement, and a rigid brace connecting the trail and each crank arm.

3. In a gun carriage, an axle including rotatably mounted depending crank arms, a trail mounted on the axle for traversing movement, and a rigid brace connecting the trail and each crank arm.

4. The combination with a gun carriage axle designed for use of relatively large diameter wheels and a trail mounted on the axle for traversing movement, of a substitute unit for the large diameter wheels comprising crank arms journaled on the ends of the axle, a rigid brace connecting the trail and each crank arm and holding the crank arm substantially perpendicular to the trail and substantially rigid relative to the axle, and a small diameter wheel on each crank arm.

5. The combination with a gun carriage axle designed for use of relatively large diameter wheels and a trail mounted on the axle for traversing movement, of a substitute unit for the large diameter wheels comprising crank arms journaled on the ends of the axle, a rigid brace connecting the trail and each crank arm and holding the crank arm substantially perpendicular to the trail, and a small diameter wheel on each crank arm.
