STANDARD ron macnrnn Guns.

1 '0 all whom it may concern Be it known that JAMns S. JoHNsro-N and fierce H. CZEGKA, citizens of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Standards for Machine Guns, of which the following is a specification, refcrence being had therein to the accompany.- in%drawings.

ur invention relates to a standard for machine guns and we declare the following to be a full, clear, concise and exact description thereof sufficient to enable anyone skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings in which like reference characters refer to like parts throughout the specification.

The object of the invention is to provide a standard for machine guns, the legs of which can be folded back against the sides of the gun when the sameis not in firing position. To this end the standard is equipped with two legs that are pivotally mounted to the frame. Furthermore, the standard is light and, therefore, adds but very light weight to that of the gun.

The object will be understood by referring to the drawings in which Fig. 1 is a perspective view of the standard- Fig. 2 is a fragmentary view, showing an end elevation of the standard;

Fig. 3 is a detail view showing a perspective of an arm employed;

Fig. i is a central vertical section of the standard;

Fig. 5 is a detail view enlarged of a hollow tube and immediate parts employed:

Fig. 6 is a detail view enlarged, showing a perspective of part of the divided sleeve employed;

Fig. 7 is an enlarged detail view, showing a perspective of a U shaped member em; ployed.

Referring more particularly to the drawings, the biped standard embodies a U shaped member 1- which forms the upper part of a casing in which the machine gun rests at the balance. The U shaped member l is equipped with ears 2-2. Each of the ears 2 has a rib 8 and an aperture 4. The rib 3 is adapted to fit into the corresponding recess 5 formed in each of the The outer sides 99 of theportion 8 are parallel with the surfaces of the ears 6, whereby to provide recesses 10 between said sides 9 and ears 6 for the reception of the upper ends 11 of the feet or legs 12. Each foot 12 is pivoted by a bolt 13 that passes through the apertures l of the ears 2 into a threaded orifice 14 made inthe stock 8.

A shell or hollow tube 15 is made integral with the stock 8. The outer end of the tube 15 has a lug 16 the upper surface of which is slightly concaved to conform with thejcir- 'cumference of the U shaped member 1-, whereby to provide a rest for the contiguous surface of the machine gun. The chamber S1011 or shaft 18 that projects well into the chamber of the tube 15. The tube 15 has an opening at 19.

The shaft 18 is surrounded by the divided sleeve having parts 2020. Each of the parts 20 is furnished with a lug 21 that has an orifice for the loose reception of the stud or boss 22 of an arm 23. The stud 24 of the arm 23 is mounted to turn within the sleeve 25 rigid with the foot 12.

A coiled spring is disposed about the shaft 18 between the inner ends of the parts 20 and the end of the chamber, whereby to normally push the divided sleeve ahead, so as to hold the foot 12 in the .full line position illustrated in Figs. 1 and 4.

When either one or both of the feet 12 is pulled'back into the dotted line position illustrated in Fig. 4;, the part or parts 20 of the divided sleeve will. slide along the shaft 18 and compress the coiled spring 30. In this latter position of the foot 1.2, the arm or arms 23 will lie almost parallel with the tube 15 and, therefore, hold the footor feet in the dotted line position illustrated in Fig. 1. Likewise, when the foot or feet are in the full line position illustrated in Figs. 1 andt, the arm or arms 23 will form a brace to hold the feet steady. Or in other words, the arms 28 form substantially a toggle joint with the legs 12 and the parts are integral with the per- .of the tube 15 is extended through the stock 2020 of the divided sleeve,jwhereby to aid in holding the legs temporarily in either one of the two positions mentioned. However, in the-event that one only of the legs 12 is pulled back to the dotted line position illustrated in Fig. 4:, the spring 30 will be compressed by the corresponding part 20 of the divided sleeve, thereby withdrawing the pressure of said spring 30 from the other part 2O 01": said sleeve and allowing the opposite leg to be held temporarily by the toggle joint connectionv of the arm 23 with the leg 12 and part 20 of the divided sleeve.

Thelower ends of the feet 12 are somewhat conical in shape to provide a point 3% that may be thrust into the earth, whereb to hold the standard steady. Caps 35, that are concaved on their under surface, are

made integral with the feet 12 adjacent the conical points 3 just referred to.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is:

1. In a standard for machine guns, legs pivotally mounted, a divided sleeve, means connecting said legs to the parts of the divided sleeve, and spring means for holding said legs ,yieldingly in one of two positions.

2. In a standard for machine guns, legs pivotally mounted, a divided sleeve, lever means connecting said legs with the parts of said divided sleeve, and a coiled spring for holding said legs yieldingly in one of two positions.

3. In a standard for machine guns, a U-shaped member, a stock portion, legs pivoted to said stock portion, a hollow tube attached to said stock portion, a divided sleeve disposed in said hollow tube, arms connecting the parts of the divided sleeve with the legs, and a spring normally pushing against the edge of said divided sleeve, whereby to hold the legs in one of two positions.

4:. In a standard for machine guns, a U shaped member for mounting a gun, a stock portion having a hollow tube attached thereto, a divided sleeve disposed. in said hollow tube, arms connecting said legs with the parts o? the divided sleeve, and yielding means for holding said legs in one of two positions.

5. In a standard for machine guns, a stock portion having a hollow tube attached thereto, a divided sleeve disposed in said hollow tube, means connecting said legs with the parts of the divided sleeve, and yielding means for holding said legs in set position.

6. In a standard for machine guns, a stock portion,,a hollow tube attached to said stock portion, a divided sleeve disposed in said hollow tube, legs pivotally mounted to said stock portion, arms connecting said legs with the parts of said divided sleeve, and a coiled spring disposed in said hollow tube, whereby to hold thelegs in a given position.

7. In a standard for machine guns, pivotally mounted legs, arms pivoted to the legs, and means pivoted to the arms, the arms forming a toggle joint between the legs and said means, whereby to hold said legs in given position, said means permitting movement and holding of one leg independently of the other.

In testimony whereof we have aliixed our signatures.
