WHEELED GUN-CARRIAGE.

Specication of Letters Patent.

Patented July 22, 1919.

Application led May 15, 1917. Serial No. 168,858.

To all whom t may concern:

Be it own that I, EUGNE SCHNEIDER, a citizen of the Republic of France, and residing at Le Creuzot, Sane-et-L0ire, France, have invented a new and useful Improvement in or Relating to Wheeled Gun-Carriages, which is fully set forth in the following specification.

This invention relates to improvements in -wheeled gun carriages adapted to slide on the lwheeled laxle for the purpose of training.

These improvements consist essentially in guiding the gun carriage upon the axle by means of a box composed oi two elements capable of sliding vertically relativel to each other, without relative longitu inal displacement; one element of the said box is carried by the carriage and the other by the axle, and metal or other springs are interposed between the said elements of the box.

By this means the body of the carriage is mounted elastically on the axle, and also in such a manner as not to interfere in any way with the freedom of slidin of the entire gun carriage along the whee ed axle.

The mechanism for eecting the sliding :of the carriage along the axle may be carried wholly by that element of the box that slides directly on the axle. In a modification, the said mechanism may be carried in part by that element of the box that slides directly on the axle, and in part by the carriage and that element of the box that is fixed to the carriage. In that arrangement, the two parts of the mechanism are connected together by a telescopic spring device whose elements are jointed by means of Cardan joints to those parts of the mechanism that are to be connected to one another.

The manner in which this invention is to be performed will now be morevparticu-y Figs. to 8 illustrate a second practical construction of apparatus;

Fig. l is a vertical section;

Fig. 5 is a horizontal section on the line V-Y of Fig. 4;;

Fig. 6 is a vertical longitudinal section on the line VI-VI of Fig. 4;

Fig. 7 is a cross section on the line VII- VII of Fig. 6;

Fig. 8 is a part section on the line VIII- VIII of Fig. l.

n In these various ligures A is the gun carriage proper, constructed so as to be capable of sliding along the wheeled axle C. According to this invention, the guiding of the carriage A on the axle, in its sliding movement along the latter, is effected by means of a box composed of two elements B, B1, extending one inside the other in such" a manner that neither can have any longitudinal movement relatively to the other. 4but is capable of sliding vertically one in-l side the other. Between these two box cle,y A

ments there are arranged springs D which may be of metal or othenwise.

In the constructional example shown in Figs. l to 3, the mechanism for eilecting the sliding of the carriage along the axle is carried wholly by the box element B1, excepting of course the part which serves as a bearing or abutment on the axle. In the example shown, this part consists of a nut c. In this nut works the screw E journaled in the box element B1, and having iixed on one of its ends a pinion F connected by wheel gear G-H-I to pinion J fixed on a shaft K. This shaft K, as likewise the axles g, L, z' of the wheels, G, H, I, are carried by the box element B1 The axle 71 is formed in the prolongation of the axle It.

In actuating the shaft K by means of one or other of the hand wheels 7c, cl mounted on its ends, the screw E is rotated, and consequently caused to move longitudinally in the nut c which is fixed to the axle C.

The longitudinal movement of the screw E and oit' the box element B1 causes the external box element B and consequently also the carriage A to move longitudinally.

In the constructional example shown in Figs. 4 to 8, the box element B1 that slides directly along the axle, carries projecting guide claws b1 (Figs. Ll--5) for the ribs b formed on the box element B that is fixed to the carriage A. This mutual `guide( device ZJ-b1-b1 prevents all longitudinal displacement of the two box elements relatively tol each other. AOne part of the mechanism for effecting the Sliding of the carriage along the axle is carried by the box .element 'B15 another part of the mechanism is carriedaby ythe carriage A and the box element B fixed tothe latter.

The part that serves to provide a bearing or abutment of the mechanism upon the axle is in this case lconstitu-ted yby a yrack c. That part of the mechanism that is carried by the box element B1 comprises a pinion L which yengages with the rack c and has its axle Z journa'led in the said boxelement B1. The axle Zicarries .also a helical pinion M which engages with a1 worm N fixed on the shaft n journaled likewise in the box element B1.

The shaft n carries further, `on each of its ends a beveled l inion N1 enO'aOinU with 7 b C D a pinion O whose axle 0 is journaled like the shaft n and the axle Z in the box element B1.

The axle o carries further, theelement P of a cardan joint PP1 the other element P1`Aof which is carried by one of the short shafts Q1 of a telescopic device Q1-Q.

l The short shaft Q1 has a key g1 slidable in a slotg in the short shaft Q. A spring R bears at its ends respectively against the two shafts Q1 and Q. The short shaft Q carries fat ,its other end, the element S1 of a Cardan joint S-S1 the other element S of which lis 4carried by the axle s journaled in a riage sliding along a wheeled axle, wherein the guidance of the gun carriage in its sliding movement along .the wheeled axle is effected by means of a box composed of two lelements carried respectively by the O'un carriage and the axle, and capable of sli ing vertically in relation to each other without relative displacement 'along the axle; metal lor other springs being arranged between the said two elements.

2. An apparatus, as claimed in claim l, wherein :the mechanism for sliding the gun carriage along the axle is carried wholly by that element of the 4box that slides directly on the axle.

ln testimony whereof I have signed this specification in the presence of two subscribing witnesses.

, EUGNE SCHNEIDER.
