organized in accordance with the laws of the State of California), of 310, Pine
Street, San Francisco, in said State of California, United States of America.]
Improvements in Automatic Guns and in Mountings therefor.
I, HENRY EDWARD NEWTON, of the Office for Patents, 6, Bream's Buildings,
Chancery Lane, in the County of London, Patent Agent, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to an improved gun of that class known as recoil-operated
guns, in which the energy developed by the recoil, when the gun is fired, is utilized
in retracting the breech block from the barrel, to open the breech, and performing
the other operations of the gun required for a new discharge.
The present invention has been made in connection with the improvements of
the magazine gun shown and described in British Letters Patent No. 9527, dated
April 14, 1897, the changes in the organization of that gun being made especially
for the purpose of producing an efficient machine or field gun employing a
movement of the same character as in the Patent above referred to, and the
improvements aiming especially at the provision of such a gun, with a magazine of
small size and large capacity, which may be conveniently and rapidly filled, and
with means by which the cartridges may be fed from the magazine at the proper
speed, and with the required certainty for their successive advance into the barrel
by the returning breech-block during the operation of the breech mechanism.
In the production of such a machine or field gun, and magazine construction,
also, the parts of the breech mechanism by which the barrel is returned to
position and the breech opened and closed by withdrawing and returning the
breech block, and the hammer held in position and released for the discharge of
the gun, have been improved, especially with a view to securing a stronger
construction and greater certainty in rapid operation in machine or field guns.
The invention includes a novel magazine construction, and novel means for
feeding cartridges from the magazine to a gun barrel, which are especially adapted for
use in machine or field guns employing a longitudinally moveable barrel and sliding
breech-block operated by the recoil; and certain features of construction and
combinations of parts in the breech mechanism of automatic guns of the general
organization of the Patent above referred to, as well as certain features of
construction which are applicable to guns employing a different breech movement,
and an improved tripod, and means for mounting the machine or field gun.
For a full understanding of the invention, a detailed description of a construction
embodying all the features of the invention, as applied in their preferred form to a
machine or field gun, and a modified magazine construction, will now be given in
connection with the accompanying drawings forming a part of this Specification,
and the features forming the invention will then be specifically pointed out in the
claims.

In giving a detailed description of the gun, I will first describe the breech
mechanism of the gun proper, after which, similar detailed descriptions will
be given of the novel magazine shown, and its operating devices, and of the tripod
construction.
Referring now to the drawings and especially to Figures 1 to 10, A is the barrel
and B the barrel extension, which may be formed integral with, or secured to, the
barrel, and C the breech block, sliding in the extension. The barrel A and extension B
move longitudinally in a frame or casing D, which, as in the forin shown, consists of
a rectangular casing surrounding the extension B, and having an opening.15 at the
bottom, for the discharge of the empty shells, and an opening 16 at the top, for the
reception of the live cartridges from the magazine. The frame D has a forwardly-
extending cylindrical portion E, which surrounds the breech portion of the barrel A,
and serves as a guide and support for the barrel during its movement. A still

page_text: further support for the barrel is provided by the sleeve E¹, hereinafter described.
The frame D has also a rearwardly extending arm or tongue F, which forms the
stock or hand grip. The barrel extension B consists of two side plates 17, joined
by a screw-threaded extension, into which the barrel A is screwed, and of a shape
conforming to the inner wall of the frame D, in which they may fit snugly, said
barrel extension B forming a casing enclosing the breech block and its operating
parts, and being open at the top and bottom for the reception of the cartridges and
expulsion of the shell, as in the case of the frame D.
The breech-block C is provided with ribs 19, which run in grooves formed in the
upper part of the sides 17 of the casing forming the extension B, and by which the
breech-block is guided and held in position. The breech-block also carries, on either
side, the spring-pressed extractors a, also running in grooves in the sides of the
casing formning the extension B. The ejector b is pivoted on pin 21 in the rear end
of the casing B, and enters a groove 22 in the under-side of the breech block C, the
forward portion of the ejector b being slightly curved downwardly, and the end
inclined. The groove at the end of the breech block C is also inclined, to conform
to the shape of the ejector, and press it down, to force the shell out of the extractors a,
when the breech-block is in retracted position, as shown in Figure 4, and the breech-
block will raise and pass under the ejector on its return. As the empty shell is
drawn back by the extractors a when the breech-block C is drawn rearward, the
upper portion of the head of the shell will pass under the inclined end of the
ejector b, which is stationary with the barrel extension B, and be pressed down by
the curved inclined surface at the end of the breech block, and thus be forced down
out of the grasp of the extractors, when it will fall between the sides 17 of the

connected to the barrel extension B by a pair of links K L, pivoted together at 23,
the forward end of the front link K being pivoted to the breech-block C by the
pivot 24, and the rear end of the rear link L to the barrel extension B by a pivot 25.
The link L is preferably forked, as shown, consisting of two side plates which embrace
the rear end of the link K, and affording space for a central hammer within the
breech-bolt.
The
Mounted in the forward end of the breech block C is the firing pin c, which consists
of a disk, having a pin on its forward side, and a central slot through which passes
the pin 24, which limits the movement of the firing pin c in both directions.
firing pin c is engaged at its rear end, and actuated for firing by a bar d, which is
practically a part of the firing pin, but is separate therefrom, to allow the link K to
turn on the pivot 24. This bar d is supported in the link K by a slot and pin con-

nection 26, to allow the bar d to be forced forward, to engage the firing pin c.
bar d extends rearward to the end of the link K, and the link I has a similar short
bar d¹ mounted in the link by a pin and slot connection, as shown, so as to have a
limited movement in the link. This bar d' is actuated by the hammer e in firing the
gun, and in turn actuates the bar d, to force the firing pin c forward, to explode
the cartridge. The hammer e carries a cross pin 27, which moves in horizontal
grooves 60 in opposite sides of the barrel extension B, being guided thereby in a
straight line, and the pin 27 passes through slots 28 in the side-plates of the link L.
The slots 28 have a horizontal portion in which the pin 27 lies, in the normal position
of the gun, and an upwardly-inclined portion, by movement in which the pin 27

lower side, a cross pin 29, adapted to be engaged by the upward extension on the
hand lever H, so that the breech can be readily opened by hand, as described
hereafter.
At its rear end, the hammer e is pivoted by pin 30 between two side plates, which
form a lever f, which is connected at its lower end to the base of the barrel
extension B by links 31, and between the hammer e and links 31 the lever is pivotally
connected by a pin 32 to two side plates g g¹, cut away on their lower edges below the
pivot 32, to clear the links 31, and adapted to move longitudinally in two grooves 33
formed in the sides 17 of the barrel extension B. The forward end of the plates gy¹are

which enter openings 37 in the forward ends of the plates g g¹, as shown in Figures 3
and 7. The rod 35 has coiled about it a spring 38, one end of which bears against,
and is held under tension by, an adjustable nut 39, screw-threaded on the outer end
of the rod 35, the other end of the spring 38 bearing against a head 40), which
connects, and forms part of, the hand lever bars 41, which extend rearward
and are pivoted to the hand lever H. This spring 38 is the operating
spring of the breech mechanism, put under tension by the recoil, and by which
all the operations of the breech mechanism are performed and the magazine
advanced. The spring 38 and rod 35 are enclosed in a casing G, screw-threaded at
its inner end to the frame D, and secured at its outer end to the under side of the
sleeve E¹ by a screw 42.
forming
The
The lever has pivoted, at 43, between its two side plates, a catch hook
the sear, by which the hammer is held in firing position, and which is released by the
trigger, this sear being adapted to engage either one of two teeth 10, 11, formed in a
catch block 44. This sear h carries a flat curved spring 45 on its upper surface, the
free end of which engages the inner curved bearing surface 46 of the stock F, so that
the spring 45 operates to press the sear h down into engagement with either one of
the two teeth 10, 11, for the operation of the gun, as hereinafter described.
sear h carries a pin 12, adapted to enter a notch 13 in the catch block 44, when the
breech block C has been retracted, and the sear h engages the tooth 10, as shewn in
Figure 4, and forms a fulcrum for the rocking of the sear h, to release it from the
tooth 10, as the breech-block returns to close the breech, and as the sear h leaves
the tooth 10, it is forced by the spring 45 into position to engage with the tooth 11
of the catch block 44. The sear his thrown out of engagement with the tooth 11 by
means of a tripper 48, pivoted to the stock at 49. This tripper 48 has two arms 5, 6,
the arm 5 entering an opening in the block 44, near the tooth 11, and the upper end
of the arm 5 lying directly beneath the sear h when the sear is in engagement with
the tooth 11. The other arm 6 extends down and forward with its end in position to
be engaged by a pivoted catch on the trigger l, and by a vertical pin 7 loosely mounted
in the the trigger block 50, this pin 7 being the means by which the trigger acts to
hold the tripper 48 in position with the sear h raised for continuous firing of the gun.
The tripper 48 is spring-pressed downward by a spring 51. The tripper 48 is actuated
for firing the gun by a swinging catch 52 pivoted, at 1, in a groove formed in the triggerl,
the end 2 of the swinging catch 52 engaging the end of the arm 6 of the tripper 48, to
swing the tripper upwards on its pivot 49, and raise the arın 5, to release the sear h from
the tooth 11. The swinging catch 52 carries a pin 3, which enters holes 4 in the side plates
of the trigger 1, the holes 4 being elongated, or somewhat larger than the pin 3, thus
allowing the catch 52 to be swung upward and downward slightly on the pivot 1.
The trigger spring 8 has a tongue 8ª, forming a light spring bearing on the top of
the catch 02, so as to return it to position, with the pin 3 at the bottom of the
holes 4. With this construction, the pulling of the trigger lifts the tripper, by the
engagement of the end 2 of the catch 52 with the lower end of the arm 6, so as to
release the sear h from the tooth 11, and the catch 52 then slips off, and passes the
arın 6, so as to allow the tripper to be returned to normal position by the spring 51,
even though the trigger be held back, thus permitting the sear h to engage the
tooth 11, when again brought into proper position therefor by the action of the breech
mechanism, so as to assure single firing. In raising the arm 6, the catch 52 is swung
upward on its pivot 1 against the tension of spring 8, so that the pin 3 is at the top
of the holes 4, and, when the catch has passed the arm 6, and is thus released, the
spring 8 swings the catch 52 downward on the pivot 1, until it is stopped by the pin 3
striking the bottom of the holes 4, this downward swinging of the catch carrying its
end 2 forward sufficiently to permit it to pass the end of the arm 6 as the trigger is
returned by the trigger spring 8, when released by the finger, and the end 2 of the
catch 52 being again brought beneath the arm 6, when the trigger is returned to
normal position, so as to engage the arm 6 again on the next pull of the trigger. To
prevent the trigger from actuating the pin 7 in single firing, the trigger is provided

page_text: |with a notch 9 directly in line with the pin 7, this notch 9 being deep enough to
allow the upward firing movement of the trigger without striking the pin 7. When
the gun is used for continuous firing, the notch 9 in the trigger is covered by a
plate 53, which is mounted on the trigger, and adapted to he moved thereon to cover
or uncover the notch 9 by a pin and slot connection 14. When the plate 53 is inoved
to cover the notch 9, the upper end of the plate 53 will engage the lower end of the
pin 7, when the trigger is pulled, and lift the pin, so as to hold the tripper 48 raised,
and the sear out of position to engage the catch 11 as long as the trigger is held
back. The spring 8, as shown clearly in plan view in Figure 10, is fast to the trigger
block 50, and, besides operating the swinging catch 52 on its central tongue 8ª, bears
by its front cross bar on the upper edge of the trigger 1, to return it to position, when
released by the finger of the operator.
Referring now especially to Figures, 1, 2, and 11 to 16, the magazine consists of
a stationary outer casing M, circular in form, and an inner rotating cartridge
holder N, in which the cartridges are packed. The casing M consists of an outer
cylindrical shell m, bottom m¹, and a removable cover m². The bottom m¹ has a
cartridge opening 99 in line with the feed opening 16 in the frame D. The bottom m¹
of the casing M also has rigidly attached to it a central vertical sleeve 70, mounted on
a vertical support 80 on the gun barrel, by being slipped over it, and screw-threaded
at the top to receive a screw 87 on the top m². This holder 80 is formed by a vertical
stud on a ring 81, which is the trunnion ring of the gun, as hereafter described, and
which is screwed onto the end of the barrel guide or support E, and receives the screw-
threaded end of the sleeve El. The rear portion of the casing M is supported by the
frame D, and its forward portion rests on a block 82 carried by the sleeve E¹, and is
held in proper position and against rotation on the holder 80 by a key or lug 83 on
the holder, which enters a notch in the sleeve 70, and by a slotted clip 84 on the rear
side of the casing, which is entered by a lug 85 on the rear sight i, when the latter
is swung up into vertical position on its pivot 120. The rear sight i also carries an
arm 121, which bears upon the top of the casing M, so as to hold it firmly against
vertical movement. The rear sight may be held in vertical position by any suitable
means, such as are well known in the art. As shewn in Figure 19, a vertically moving
catch pin 122 is used, engaging a notch in the sight support. The inner casing or
holder N has an outer shell n and an inclined top n¹ sloping inward to an inner
shell n²; its central portion being horizontal. Depending from the top n¹ is a central
sleeve 86, journalled on the sleeve 70 of the stationary casing M, and supported by
shoulders formed on the sleeve 70, so as to be free to rotate thereon. The upper
portion of the outer shell n of the holder N is just within the cover m² of the
casing M, the top n of the holder N sloping down and inwardly to the inner shell n²,
at about the inclination of the top row of cartridges. The cartridges are placed in the
holder, as shown, in radial vertical rows of five, the rows being separated one from
the other by radial partitions 88, 89, which form stalls receiving the opposite ends of
the cartridges, and the bottom cartridge of each row resting on the bottom m¹ of the
casing M.
The cartridges are brought at the proper time to the opening 99 in casing
bottom m¹ and opening 16 in the upper part of the gun frame D, and forced
through these openings, and in front of the retracted breech-block, in the following
manner:-
Pivotally mounted on the outer side of the gun frame D, at 90, is a rocking lever J,
the lower portion of which is formed of two fingers 91, 92, which are alternately
engaged by a lug 93, carried by the sliding plate g, the frame D having a slot 94
through which the lug 93 moves, and the parts being covered by a casing j on
frame D. The upper end 95 of the rocking lever J is circular, and projects through
a slot 96 in the bottoin m¹ of the casing M, and enters an opening in a horizontally
swinging plate I, having a projection forming a pawl 97, which engages teeth formed
on the under side of a ratchet ring 98, fast to the holder N. The plate I is pivoted
loosely on a stud 100, rising from the bottom m¹ of the casing M, and coiled about
the stud 100) is a spring 101, one end of which is fast to the plate I, and the other

page_text: end is connected by a link 102 to a swinging cartridge guide 103, which is pivoted
at 104 to the underside of a table 105, so as to swing below the latter over the
opening 99. The table 105 extends rearward relatively to the movement of the
holder N from a point in advance of the opening 99, and is arranged with its rear
edge on the line between the first and second layers of cartridges, so as to allow
only the lower layer of cartridges to pass to the opening 99, the second layer passing
over the upper surface of the table, and gradually falling to the bottom of the
casing M, over the inclined table support 124, so that the second layer, as the
cartridges approach the table, is advanced over the top of the table, and, after passing
the table, becomes the first or bottom layer, from which the gun is fed, and so on for
each successive layer.
The spring 101 is normally under tension, to hold the pawl 97 against one of the
teeth of the ring 98, and when the plate I is swung to the position shewn in
Figure 14, to move the holder N forward, the tension of spring 101 will be slightly
increased by reason of the link 102 and swinging arm 103, which at this time are
given a greater movement than the plate I by the forward cartridge of the bottom
layer, which is being moved to a position over the opening 99, pressing against
the swinging arm 103, and forcing it forward or away from over the opening 99.
The guide 103 is pivoted in such a position that it will normally lie across the
opening 99 at an angle, as shown in Figure 13, and when the holder N is
moving, and the cartridge next the opening 99 is being moved over the opening, it
will press the swinging guide 103 back to the position shewn in Figure 14 against a
block 107, and the under-side of the guide 103 is curved or inclined, so that the
guide 103 acts to force the cartridge down through the openings 99, 16, as the
spring 101 acts through link 102, to move the guide back to the position shown in
Figure 13. The cartridge passes through the openings 99, 16, from the position
shown in Figure 12, and down in front of the breech block C, when the latter is
retracted, and is caught, and prevented from falling out of the path of the returning
breech-block by two curved supports or holding plates s, shown in Figures 4 and 12,
which catch the rear portion of the cartridge, and support it while the forward end is
supported by a rest 106 in position to be forced into the barrel, this rest 106 forming
part of the barrel extension B, and supporting also the forward end of the breech-
block, when the breech is closed. In Figure 12, a cartridge is shown in full lines in
the position it occupies in the openings 99, 16, during the withdrawal of the breech-
block, and in dotted lines after it has been pressed down by guides 103 in front of
the retracted breech-block.
A follower O, resting on the top of the cartridge, is also provided for the following
purpose:-
When the magazine has been emptied with the exception of the last layer on top
of the table 105, the cartridges, in moving over the edge of the table 105 while
the holder is being rotated, may rebound, and to prevent this, the ring O, preferably
formed of a comparatively wide plate, as shown, is hung on the magazine in such a
manner that it will follow the cartridges downward, as they move towards the bottom
of the holder, and press upon them, to prevent rebound, and secure their proper feed.
For this purpose, the ring O is suspended by links 109 from the top n¹ of the holder N,
as shown in Figures 2 and 11, the links being of the proper length, and arranged to
allow the ring O to lower with the layer of cartridges in the magazines on which
it rests, so that the ring holds the cartridges down, so as to assure the last layer
passing over the edge of the table without rebound.
With the construction above described, when the gun has been discharged, and the
barrel and breech block with their operating parts have, by the recoil, been forced back
to the position shown in Figure 3, the lug 93 will have engaged the finger 91 of the
rocking lever J, and thrown the lever J to the position shown in dotted lines in
Figures 2 and 3, withdrawing the pawl 97 into the position shown in Figure 13.
Then, as the links K, L, are broken down, and the sliding plate g is moved forward by
the tension of the operating spring 38, the lug 93 is moved from the dotted position
shown in Figure 3 forward to the dotted position shown in Figure 4, without

page_text: actuating lever J, but is then in position to engage finger 92, and actuate the lever
on further movement of the plate g, and such further movement occurs during the
return of the links and breech-block to normal position. The moving of the lever J
during this return of the breech-block, will, through the end 95, swing the plate I in
the direction of the arrow in Figure 13, to the position shown in Figure 14, and the
plate I will, through the pawl 97, which engages the toothed ring 98 fast to the
holder N, move the holder a space of one tooth, that is, the distance between the centre
of two cartridges. This movement of the holder will bring a cartridge over the
openings 99, 16, and the guide 103 will force the cartridge partially through these
openings on to the top of the breech-block, which is then in its normal position, closing
the breech. The fingers 91, 92 are formed on their lower surface so as to allow the
lug 93 to pass under them, when the lever J has obtained sufficient movement, and
act as a lock to prevent swinging of the lever, J. There is preferably provided a two-
leaved spring plate 2, fastened to the bottom m¹ of the casing M, one leaf 108 of
which engages a tooth of the ring 98, to prevent over-throw, and also to press the
pawl 97 into engagement with the tooth 98, next to be engaged, as it returns to
engaging position, and the other leaf 108 engages a tooth 98, to prevent a backward
movement of the magazine, as shown in Figures 15 and 16.
Figures 17 to 26 show a modified construction of the magazine, and means for
rotating the holder N. In this case the lever J is dispensed with, and the pawl 97
forms a part of the lever 110, having a vertical slot entered by a bar 111, having, on
its lower surface, two studs 112 and 113, and on its upper surface a stud 114. This
lever 110 is mounted in an opening 115 in the underside of the sight block 116, and
normally pressed against the upper surface of the opening 115 by a spring 117,
carried by the lever, and hearing on the gun frame D. The bar 111 is journalled in
the sight block 116, and the upper face of the frame D by the studs 112, 114, and
the stud 113 runs through a slot 118 in the frame D, and enter a cam groove 119
in the upper face of the breech-block C. When the breech is closed, the pin 113 lies
in the position shown in dotted lines in Figure 20, and, as the breech block is
retracted, the pin 113 will be actuated by the cam groove 119 to the position shown
in full lines in Figure 20, and thus throw the bar 111, and consequently the pawl 97
which engages the teeth 98, from the position shown in Figure 21 to the position
shown in Figure 17, and bring a cartridge over the opening 99 formed under the
table 105. In this construction, the moveable guide 103 is omitted, and the table.105
is slightly inclined toward the opening 99, and curved about the opening, as shown
clearly in Figure 18, so as to form a guide, and act to press the cartridge down into
the gun, as it arrives over the opening. As the breech-block moves forward to close
the breech, the cam 119 will operate to move the pawl 97 in the opposite direction, the
spring 117 allowing the end of the pawl to lower, as it moves along the incline of
the tooth 98, until it passes the point of the tooth, and then raising the pawl to
engage the tooth.
It will be seen from this that the lever 110 has a slight rocking
movement on the bar 111, and, as the lever is held against the upper surface of
the sight block, the rear end of the lever 110 is slightly rounded or curved, so as to
allow the lever to tilt slightly, as the pawl 97 is forced down by the incline of the
teeth 98. A plate or cover w, as shown in Figure 26, may be used for closing the
opening 99, when desired for any purpose, as for re-serving the magazine.
The construction shown in Figures 17 to 26 is otherwise the same as that shown in
the other figures, and previously described. To refill either of the magazines, the
rear sight is turned down, and the magazine, including casing M, raised off the
support 80. The cover m² of the casing M is then removed, and holder N drawn off
the sleeve 70, and placed top down and refilled. The casing M is then placed over
the filled holder, and the casing and holder then turned top up, and the cover m²
replaced, when the entire magazine may be replaced on the gun, as before.
The gun may be mounted in any suitable manner, but it is preferred to use a
tripod X, shown in Figures 1 and 14, the legs of which are attached at the upper
end to a head 71, in which the gun is hung by trunnions 72 on trunnion ring 81,
previously described. The trunnion box on the head 71 is composed of an externally

to be placed in the trunnion box. A ring 74 is then screwed on over the trunnion
box 73, and a two-part cap plate 75 is fastened to the end of trunnion 72 by screws
or otherwise, thus preventing any dust or dirt from entering the trunnion box. With
this construction, the parts are such that they can be readily renewed when broken or
worn.
A handle or shoulder rest P is shewn, which is screwed on to a projection on
the stock of the gun, for convenient removal. The rear leg of the tripod is
pivoted at the upper end to the head 71, and consists of a tube which receives the
bar x adjustable in the tube, so as to lengthen or shorten the leg. The lower end of
the tube x is shown as split, and encircled by a clamp 76, which clamps it tightly to
the rod x¹. An adjusting clamp 77 on the tube x is connected by a chain 78 to the
head 71. The other two tripod legs y Ty carry, at their upper ends, intermeshing
geared segments 79, so that they, move outward or inward together. The tripod may
be adjusted so that the gun.is fired from a high position, or close to the ground. As
shown in Figure 1, the gun is raised. When the gun is to be lowered, the clamp 77
is moved upwards on the legs X towards the head 71, and the chain 78 is thus

mounted on the rear leg r, its front end being supported on the leg by clamp 126,
and its rear end by link 127, connected to clamp 128 on the leg x.
The seat may
thus be adjusted to any desired position of use by moving the clamps 126, 128, or the
seat and link 127 may be closed against the leg a for packing.
The operation of the gun will be understood from a brief general description in
connection with the description of the parts heretofore given, and the drawings,
referring also to the Letters Patent above cited..
Assuming that the parts are in the position shown in Figure 2, and that the gun
has just been discharged, the recoil carries the barrel A and barrel extension B rear-
ward together to the limit of the recoil movement, as shown in Figure 3, the breech
block C moving with the barrel and barrel extension B. This movement of the barrel
and barrel extension forces the lever f backward bodily by the connection of the
upper end of the lever to the hammer e and the connecting links 31 between the lower
part of the barrel extension B and the lever f. The lever f is thus moved back until
the sear h engages the tooth 10 in the catch block 44, and the spring 38 is thus
compressed against the head 40 by the plates g, g¹, moving back with the lever f.
During this movement, the links K L are held in normal position, and the breech
block C locked to the barrel by the pin 27 moving in slot 60, and the straight
portion of slot 28, so that the barrel extension B receives the full force of the
recoil.
The
When the force of the recoil is expended, and the barrel free to return, the spring 38
will expand, and, as the lever f is held by the sear h and tooth 10 of the catch
block 44, the lever f will be operated, as a lever, with its fulerum at the pivot 43, and
the lower end thrown forward, and its upper end rearward, as the plates g, gl, are
returned by spring 38 toward their normal position, and, by this action, the lower end
of the lever factuates the barrel extension B through links 31, and returns the barrel
to its normal position, at the same time throwing backward the upper end of the
lever f, to throw back the hammer e, which is connected thereto by pin 30.
pin 27 of the hammer e travels in the straight portion of the slot 28 for a short
distance during this movement, and then enters the inclined portion of the slot, and
breaks down the links K, L, and the link L is then actuated as a lever with its fulcrum
at 25, and the power applied by the pin 27, and through the link K connecting the
other end of this lever L to the breech block C, draws the latter back, to open the
breech, as the barrel reaches its normal position. When the breech block is nearly
withdrawn, and the barrel is nearly returned to position, so that the breech is open
for the discharge of the shell and the insertion of the cartridge, the forward end of
the ejector b strikes the head of the cartridge shell held by the extractors, and
forces it out of the grasp of the extractors, and down and out of the opening 15 of
the frame D. The parts are now in the position shown in Figure 4.

page_text: During these operations of the different parts, the magazine-actuating lever J has
been moved by the plate g, lug 93, and finger 91 of the lever J, from the position
shown in full lines in Figure 2 to the position shown in dotted lines in the same
figure and in Figure 3, and the pawl 97 of the plate I thus moved back into
position to engage a tooth on the ratchet 98, which occurs when the parts are as
shown in Figure 3, the position of the lever J at that time being shown in dotted
lines in this figure, the lug 93 running under the finger 91 during the latter part of
this movement, so as to lock the lever J in position. Figure 13 shows this position of
the pawl.
As the spring 38, in its return movement, operates to return the barrel A to normal
position, and to break down the links K, L, to withdraw the breech bolt from the
barrel, and open the breech, as previously described, and to bring the parts into the
position shown in Figure 4, the forward movement of the plate carries the lug 93
from under the finger 91, and into position to engage the finger 92, as shown in dotted
lines in Figure 4, but does not actuate the lever J.
During this movement of the breech-block, the cartridge that has entered the
openings 99, 16, and is then in the position shown in full lines in Figure 12, lies upon
the top of the breech block, and the spring 101, which has been put under increased
tension by the backward movement of the plate I, as above described, presses the
curved surface guide 103, so as to tend to force the cartridge downward. As the
breech-block reaches its rear position and the breech is fully opened, the support of
the cartridge by the breech-block is withdrawn, and the cartridge passes down through
opening 16 into the position shown in Figure 5, in which it is supported throughout
the rear portion by the plates 8, and at the point by the support or rest 106. The
cartridge is moved downward through opening 16, not only by gravity, but by the
pressure of spring 101 upon guide 103, so that the latter acts to force the cartridge
down with a quick spring movement. The guide 103 is thus moved over the
opening 99, and into the position shown in Figure 13, so as to close the opening, but
yield, as before described, for the feed of the next cartridge.
The barrel is now in normal position, the breech fully open, and a cartridge in
position for loading, the next movement being for the return of the breech-block to
close the breech. The sear is now rocked, upon the point of the pin 12 resting in
the notch 13, on block 44, so as to raise the sear hook out of engagement with tooth 10
on block 44, against the tension of spring 45, and, as the sear is released from the
tooth 10, the spring 38 acting through the plates g g¹ upon the lever f, rocks the
leverf forward upon the pivot formed by its connection to the link 31, the connection
of the link 31 to the barrel extension B being now stationary, as the barrel has returned
to normal position, and the hammer e is thus moved forward by the upper end of
the lever f, so as to swing the links K, L, upward by the pin 27 acting in the slot 28
in link L, and thus open the links, and return the breech-block to position to close the
breech, the breech-block during this movement engaging the head of the cartridge,
and moving it forward into the barrel, with the extractors grasping the rim of the
cartridge shell, as usual. The position of the parts with the breech block C, partially
returned, and just engaging the head of the cartridge supported by the plates 8, to
move it forward into the barrel, is shown in Figure 5. During this return movement
of the breech block, the sear hook moves over the top surface of the catch block 44,
between the catches 10, 11, and is pressed downward by the spring 45 into position to
engage the catch 11, and hold the hammer e back from the forward end of the slot 28,
so as to permit a slight forward movement of the hammer, sufficient to actuate the
firing pin for the discharge of the gun, when the sear is released from the catch 11,
as previously described. When the breech-block has been fully returned to position
to close the breech, the breech block is locked in position by the pin 27 in the straight
portion of the slot 28, and all the parts are in the position shown in full lines in
Figure 2, except that the hook of the sear his in engagement with the forward catch 11
of block 44, and the hammer e and upper end of the lever fare thus held back
correspondingly, as indicated in dotted lines in Figure 2. During this return movement
B

page_text: of the breech-block, the lug 93'engages and actuates the finger 92 of lever Jļ and thus
rocks the lever J'from the position shown in Figures 3 and 4, to that shown in full'
lines in Figure 2, which movement of the lever J, through the projection 95, actuates
the pawl 97; to move it from the position shown in Figure 13 to that shown in
Figure 14; and thus rotate the holder N to carry a cartridge over the openings 99, 16,
and this cartridge then falls, and 'is pressed down partially through these openings by
the guide 103, and into the position shown in full lines in Figure 12, resting upon the
breech block.
The parts are now in position for discharge, and, upon the pulling of the trigger l,
the tripper 48 will be swung upwards, and the sear h released from the tooth 11 by
the tripper arm 5, when the spring 38, which has been held from full return by the
engagement of the sear h with the catch 11, will 'rock the lever f'forward from the.
position shown in dotted lines in Figure 2, to the position shown in full lines in
the same figure; and thus, through hammer e bars d, d¹ and pin c, explode the
cartridge (see Fig. 4), when the operation 'above described will be repeated!
The above description applies to the operation of the gun in single-firing; with the
plate 53 moved down on the trigger l, into the position shown in the drawings, so as
to uncover the opening 9, and prevent the movement of the pin 7' by the trigger:
The operation in continuous firing is the same, except that the plate 53 is moved¹
upward on the trigger to cover the opening 9, so that' the pin 7' is- raised' by the-
engagement of the plate 53 therewith as long as the trigger is held back, and
the arm 5 of the tripper 48 thus held in the position to prevent the engagement
of the sear 'h with the catch' 11; as the parts reach the position shown in dotted
lines in Figure 2, with the result that the sear passes the catch 11, and the
lever f and hammer e are moved forward automatically into the position shown
in full lines in Figure 2, and the cartridge exploded for the next! discharge.
This operation will be repeated as long as the trigger is hield' back, until the
cartridges in the magazine are exhausted.
To load the gun by hand; the handle end of the hand lever H'is thrown forward,.
thus moving the upper part' or fork of the hand lèver H' rearward, to engage the
pin 29' of the hammer e, and move the hammer rearward;, thus rocking the
lever frearward' upon its pivot to the link 31, to break the links K, L, downward,
and withdraw the breech block to open the breech, this movement also withdrawing
the plates g, g¹; so as to actuate the lèver J and cartridge holder N, to feed a cartridge
in the same manner as previously. dèscribed, and the hand lever H is then thrown
rearward; to move the hammer 'e back, and move the breech block forward, to close
the breech; the sear h then engaging the catch 11 on block 44, to hold the hain mer
cocked in the same manner, and the cartridge being carried into the barrel by the
returning breech block, all'as previously described. The hand lever is thus operated
without compressing the spring 38, as the spring 38 bears against the head' 40 of
the handle lever bars 41, and this head 40 moves with the handle lever H, so
that the tension of the spring 38 is thus equalized by tlie corresponding movement of
the head 40 and the plates g, g¹, in the rearward movement' of these meinbers,
while the head 40, acting upon the spring: 38; pulls the plates g; g¹, forward to
actuate the lever f, and close the breech, as the hand lever is returned' to
normal' position. It is obvious from the drawings that the hand lever is locked'
in normal position when fully returned by the bars 21 and' head 40 abutting
against the spring 38! The hammer may be uncocked' by hand by throwing the
hand lever H so that its upper end; by engagement with the pin 29; holds the
hammer e back against the tension of spring 38, then pulling the trigger to release
the sear h, and allowing the hammer to inove forward against pressure on hand
lever Hi
While the magazine construction shown; and means for operating the magazine;
are especially adapted for use in recoil-operated guns, and' the invention consists in
part' of combinations including features of construction iù such guns; the especial
object' being to provide an improved automatically-operated' gun with a magazine of
