CHARLES Summit, or susnsnns, FRA CE- GAS-CONTROLLING ATTACHMENT'FOR GAS-OPERATED GUNS.
Original application filed March 25, 1921, Serial No. 455,701. @Divided and this application filed February 27, 1922. Serial No. 539,517. a I
'Z 0 all whom it may concern: I Be it known that I, CHARLES SUTTER, a .citizen of'the Republic of France, residing. at Suresnes, Seine, France, have invented .certain new and useful Improvements in .Gas-Controlling Attachments for Gas-Op- I, erated Guns; and I do hereby declare the following to be a full, clear, andgexact .description ofthe invention, such as will en- 10. able others skilled in the art to which it appertains to make and use the same.
4 .My. present invention relates to improved means ,for regulating or controlling, the relative amount ofthe powder gases delivered .1 from the bore of the gun to the motor piston in a gas operated gun.
The violence of the recoil of the motor piston would, of course, depend not only ,upon the work it is called uponto do, but primarily uponthe volume and pressure ofv the powder gases that escape from the barinder containing the motor piston.- In order to have the gun work w1th regu- 2 5 larity, it is desirable to have the passages clear through which the powder gases pass from the gun barrel to the cylinder, and substantially uniform in minimum cross section; I There is a tendency, incident to j the operation of such guns, for these pas- .sages to become clogged up due to the solid jmatter carried along with the gases which adhere 'to the walls of the passage or pasages and ultimately clog up the same.
40 become clogged or. choked for any reason,
and to prevent any clogging up of such of the, gas-ports as are out of action for the time being. while the gun is in operation.
A further object of. the invention is to ensure a perfect. gas-tight joint for preventing any leakage of the. powder gases as they'tra'vel between the gas-port formed in the gun barrel and the gas-port formedin the nozzle head ofthe device.
.50 M resent invention is es eciall in- .l y P p y.
"tended as a division'of my application entitled Improvements in automatic machine 7 guns,-filed March 25, 1921, Sera- N 0. 455,701.
My invention will be more fully understood after. reference to the accompanying Myp resent invention relates not only to w ducts or passages, say three 7, f and 7, the.
interfering with the proper fit of the @plug F drawings, in which like parts areindicated by similar reference symbols throughout the I several views, andin which H Figure 1- shows a side elevation of part of the barrel pcrtion of a'gas operated gun with the cylinder, for the motor piston at tached, parts. being shown in section. 1
Figure 2 shows in side elevation, on a larger scale, the arrangement by means of which the amount of powder gases delivered ,to the motor piston may be .modified according to I requirements.
= Figure I 3 shows a vertical longitudinal section of the parts shown in Figure 2.
Figure eL-shows a. section along the line 4-4 of Figure 3, looking in the direction of the arrows, parts being shown in elevation; and
Figure 5 shows. a section along the line 55 of Figure 3, lookingin the direction of, 7 5.
the arrows, parts being shown in elevation. ,rel. of the gun'and enter the operating cylserves also as the carrier ring of the piece.
Thisband is fitted over the barrel A and I has the gas-ports which registers with the gas-port a from, the horse, and also has the gas-delivery'porte formed in the nozzle head 6 In the ring-E is bored transversely a cylindrical'slot 6 into which isfitted a plug F, provided with an angular opening 7" into which may be introduced asuitable instrument, such as a key, for rotating the plug when desired.
The plug F is formed with ainumber of 9 5 diameters of which differ. The diameter of each. duct' may be chosen at will for the 'purpose of. duly modifying the amount of the powder gases delivered to the motor piston. Those-portions of the periphery of the plug debouchinto the perforation 6. may be re duced n diameter as shown at 7, f, Fig .5, so as .to minimize fr1ct1on,w1thouthowever f-The plug maybe held in its adjusted position' by means ofla set screw G. ,3 v
Assuming that it be desired to allow a relatively limited amount of the powder '110 I 'F from which theductsf, f and fido not time securing zv'continuous gas-tightcon necti'on'between ports'e and e on'the one e the gunner selectssay the duct f and causes it to communicate with thetwo-said gas-ports. WVhen the plug'F is properly ad- .escape of auportion of the powder gas, a cylinder fast to the gun, and a motor piston adapted toreciprocate in said fc-y-linder,"'of a band secured on said barrel and provided justed for theselected duct f. the gunner drives the set screw G home, so as to causethe oppositeside. of the-periphery 0f theplug to make a gas-tight joint against the opposite wall of the perforation 6 and effec'tivel'y' prevent any gas reaching the remaining ductssayf f while at the 'same hand and duct ffon the other. I
omaeasng theset' screw f l h F becomesfl'oo'se' and" may be [adjusted to i another pos'ition'and is then tightened up" agaimwhile furthermore it may be readily? removed-altogether"for purposes of'exa min'ationand cleansing, if and when required. Finally, the device i's',"or maybe,=equipped w'ith'suitable marks which, being made visible from theeXterior, will*enable the gunner "clesir ed; but obviously thenumber. of saidvill of, the"mannfacturer.

."Having thus described my" invention what I claim and desire to secure by fLett-ers Pat- "e'nt'ofthe UnitedStates is with the barrel and carrier ring delivering ducts in the wall'sthereof, both orifices of with the barrel and carrier. ring delivering substantially cylindrical pl'ugha'ving. a series.
