To (ill whom, it may concern:

Beitknown that we, JOHN F. HEIGS, a citizen of the United States, and SIGARD A. S. IIAMMAR, a subject of the King of Sweden 5 and Norway, both residing at South Bethlehem, in the county of Northampton andSrate of Pennsylvania, have invented certain new and useful Improvements in Shield-Mounts for Guns, of which the following isa specifi- 1O cation.

' Our invention relates to means for protecting gunners in connection with gun-mounts; and it consists in the construction of the shield and its support on .the gun-mount, as

fully set forth hereinafter, and illustrated in the accompanying drawings, in which- Figure 1 is an elevationof a gun-mount and shield embodying our invention. Fig.

2 is a perspective view of the shield; Fig. 3,

a plan showing the top carriage and brackets in part section.

The pedestal A supports the top carriage B, consisting mainly of the yoke 3, having a pivot 1 turning in the pedestal, and a cradle C, with trunnions 8, having bearings in the yoke'piece, said cradle supporting the gun D.

The shield M consists of a metallic plate bent on a line extending approximately transversely through the gun to make the section of the shield above the gun inclineat a greater angle than that below to deflect to as great an extent as possible projectiles striking this part of the shield. The shield has an opening for thepassage of the barrel of the gun,

5 which can slide in the cradle. The top carriage supports the shield through the medium of two brackets N N, each of which is connected at one end to the lower and at the other end to the upper section of the shield,

40 while the central or intermediate portion is bolted to the top carriage or yoke. As shown,

the lower portion of the bracket is bent upon itself to form a loop, to the free end of which the shield is attached, while the upper end of the bracket extends above the carriage or yoke and is rearwardly inclined to conform with the angle of the upper shield-section.

' he forward faces of the top carriage or yoke 3 are formed to constitute bearing-faces for go the central parts of the brackets N N, each being bolted to one of said faces by bolts c.

As thus attached the shield is rigidly sup names to this specification in with the gun about its pivot, so that the opening in the shield need be only as wideas the barrel of the gun. It will be seen that by bolting the brackets to the front faces of the top carriage or yoke much more extended bearings can he, had than could otherwise be obtained, thereby securing a firmer support.

To avoid the injuries resulting from the detachment of bolt-heads by the action of projectiles, we make use of bolts or rivets fwith flaring heads and countersink the openings in the shield to receive said heads, the ends of the bolts therefore being flush with the ported to move outer face of the shield.

Withoutlimiting ourselves to the construction shown, we claim- 1. The combination with theyoke of a gun- 7o mount, of a shield through which the gun extends, and brackets supporting the shieldat their opposite ends and centrally connected to the forward faces of the yoke, substantially as set forth.

2. The combination with the yoke of a gunm ount, of a shield through which the gun extends, and brackets supporting the shield at their opposite ends and centrally connected to the forward faces of the yoke, the lower ends of the brackets being loop-shaped, substantially as set forth.

3. The combination with the yoke of a gunmount, of a shield throw ;h which the gun 'extends, and brackets each connected at its opposite ends to the shield at points above and below the top of the yoke and at intermediate points to the yoke, substantially as set-forth.

4. The combination with a gun-mount, of

a shield extending above and below the gun at different angles, and brackets each centrally connected to the gun-mount and at their ends to the shield above and below the line on which it is bcnt,substantially as set forth.

In testimony whereof we have signed our the presence of two subscribing witnesses.
