MEANS FOR SECURING Tl-lE PlVOTS 0F GUNS T0 CARRIAGE-AXLES.

sPncIFrcA'rioN forming part of Letters Patent No. 717,364, dated December eo, 1902.

Application filed June 13. 1902.

To all whom it may concern:

Be it known that I, GUSTAVEHRHARDT, engineer, acitizen of the United States of America, residing at Eisenach, in the Grand Duchy of Saxe-VVeimar and German Empire, have invented certain new and useful Improvements in Means for Securing the Pivots of Guns to Carriage-Axles, of which the follow-l Y the locking or securing device is not fitted to the pivot-gudgeon itself, but to the boss or shoulder above it. Segments are employed; but they do not form a closed circle, because, as illustrated by Fig. 2, the boss or shoulder of theA pivot is flattened on both sides. The shoulder a, with which the pivot b rests on the axle c, overlaps two concentric raised portions d, of rectangular section, integral with the axle. (See Fig. 3.)l These raised portions have concentric grooves c turned therein, which correspond with similar grooves f in the shoulder of the pivot, so as to form, respectively, one continuous groove each. Suitably shaped segments g are inserted into Serial No. 111,526. (No model.)

these grooves. curing-segments only are applied in each instance. Each segment has at one end a stoppin h (see Fig. 4) to serve as a stop in the operation of inserting the segment, while at the other end each segment has an eye to receive a pin for securing it against falling out. Each segment is fastened to the axle by means of a chain, which also serves as a handle for pulling it out. This arrangement has the advantage of oiering a large smooth bearingsurface to take up the strain vof the shock.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed,

I-declare that what I claim is In a device for securing the pivot of guns to the carriage-axle, the combination of an axle provided with raised portions, said raised portions having grooves therein, .a pivotgudgeon provided with shoulders fitting over the raised portions of said axle, said pivotgudgeon having a circular groove therein, the

groove in said pivot-godgeon and the grooves in said raised portions being concentric with.

each other and registering together, a plurality of segments tting into said concentric grooves, and means for retaining said segments in position.

In. testimony whereof I'have hereunto set my'hand in presence of two subscribing witnesses.

GUSTAV EHRI-IARDT'.
