Improvements in Machines for Applying Jackets to Projectiles.
We, MYRON CLARK LISLE and FRANK ARTHUR SIMONDS, residing respectively
at 58, Turner Street, and 256, West Broadway, in the City of Grand Rapids, in
the County of Kent and State of Michigan, United States of America,
Mechanical Engineer and Manufacturer, respectively, 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 improvements in machines for applying jackets to
projectiles, particularly projectiles for small arms, said jackets being made of
small twine wound spirally and applied to the projectiles the latter being made
of lead or other soft metal; and the object of the invention is to provide a machine
that will operate automatically and provided with certain new and useful features
hereinafter more fully described and particularly pointed out in the claims,
reference being had to the accompanying drawings in which:

Like letters and numbers refer to like parts in all of the figures.
A represents any suitable frame to support the various operative parts. B
is the driving pulley, C the driving shaft having longitudinal slot C₁ ter-
minating near the end of the shaft in lateral extensions (" having faces
inclined toward the end of the shaft. Surrounding the inner end of the
driving shaft is a longitudinally movable tubular spindle D having a pin D¹
traversing the slot C₁ and engaging the lateral extensions C" of said slot.
Said spindle extends beyond the end of the driving shaft and is reduced
and journaled in the frame A and terminates in a corrugated socket to
engage and rotate the projectile 23. Said spindle is reciprocated upon the
driving shaft by means of a bell crank lever J having a telescopic extension L
terminating in a fork K pivoted to opposite sides of a ring H rotative between
flanges I on the spindle. A pivoted lever Q has a forked end engaging a pin 1 in
the horizontal arm of the bell crank J and the outer end of said lever is provided
with an incline Q₁ engaged by a stud l' on the notched wheel N operated by a
crank-pin M on the driving shaft C and yieldingly held from turning by the

page_text: spring O. A spring S having a roll R engaging the levers J and Q presses said
levers upward and forces the spindle against the end of the projectile 23. The
opposite end of said projectile is engaged by a rotative socket E journaled in a
bearing longitudinally adjustable in the frame A. Above the spindle and
driving shaft is an inclined feed tube Y to convey the projectiles and having a
downward and lateral extension Y¹ below its lower end to receive the pro-
jectiles in succession. Z is a pivoted lever having one end turned downward and
extending through an opening in the top of the tube Y to stop the column of
projectiles in the tube and having its opposite end engaged and depressed by
the yoke K to release said projectiles and allow them to move forward.
spool 21 is journaled on a suitable support 45, on which spool is wound the
twine 22 of which the jackets are formed.
A
An oil reservoir 20 is provided having an oiling wick 19 over which wick
the twine 22 passes on its way to the guide arm. 18. Said arm has a head 29 pro-
vided with a central opening somewhat smaller than the twine through which
opening said twine passes. To permit the twine and knots or other enlarged
parts of the same to pass through said opening and at the same time maintain
frictional contact with the same, the end of said arm and the head thereof are
divided longitudinally into two parts and the detached part pivoted to the other as
at 30 and a spring 31 is also provided to press the parts of the head together.
A hook 32 on the under side of the fixed part of the head engages the twine and
keeps it in the central opening of the head. A counter shaft & is provided and
connected to rotate in unison with the driving shaft C by means of gears G¹ and
provided with a screw thread G to engage a half nut in a carriage U, longitu-
dinally movable on the rod T and also rotative thereon. Said carriage is moved
forward by said screw thread and held in engagement therewith by a spring 44,
and is moved backward by means of a spring V surrounding the rod T and
engaging the frame at one end and the carriage at the other end. Longitudinally
movable in an opening in said carriage is a thread cutting tool 13 pressed toward
the projectile by a spring 12 and away from the same by a lever 11, when said
lever engages an adjustable stop 15. On the carriage U is also a beak 17, divided
vertically and grooved in its adjacent faces through which grooves the twine 22
passes to the projectile. Said beak is pivoted to turn longitudinally as shown
in Fig. 13 and is provided with an arm 33 engaged by a spring whereby the beak
is turned toward the extension Y and yieldingly engages the same to the extent
of about one revolution of the screw as the carriage is moved back to the beginning
of its traverse. Pivoted upon the frame is a hammer X having its head above
the rear end of the projectile 23 and provided with a head 6 having a cupped
end and concave edges at two sides of the cup as shown in Figs. 9 and 10 and
the other end of said hammer extends downward and is provided with a lug 4
to engage a hook 3 attached to the carriage U. A spring 2 engages said hammer
and holds it yieldingly and normally with the end of the head 6 a short distance
from the projectile.
Said hammer is also provided with a shoulder 35 to engage the end of a
pivoted dog 5, the other end of which dog is engaged by a projection 36 on the
side of the hook 3 to release said dog and let the hammer X fall. A stop 9*
engages the hammer and prevents it from striking too forcibly. W is another
hammer to operate near the other end of the projectile being pivoted to the
frame and provided with a head terminating in a cutting tool 14 and a chisel
face 16 at right angles thereto. Said hammer is yieldingly held by a spring 10
normally with the head thereof close to the projectile and is provided with a
stop 9 to limit its movement. A lug 7 on said hammer engages the inclined
side of a triangular plate 8 on the carriage U to raise and release said hammer.
Connected at one end to the arm of the lever J that reciprocates the spindle D
is a rod 26 arranged to move longitudinally in the frame and having near its 5
other end a plate 27 pivoted at one end in a longitudinal slot in said rod and
laterally movable therein being limited in said movement by lugs 37 and 38.

page_text: Said plate is yieldingly held with the lug 37 engaging the rod by a spring 40
and is provided with an inclined flange 39 to engage a lug 28 on an arm 41,
said arm being pivoted to the frame and engaging a spring actuated latch 25.
Said latch is provided with a shoulder 42 to hold said arm when raised and a
shoulder 43 to hold the same when lowered. 24 is a tube through which the
projectiles are discharged from the machine.
The operation of the device is as follows:
The projectiles to be jacketed are fed point forward in succession into the
tube Y and by gravity move forward until the first one in the series is at the end
of the said tube and resting on the spindle D. When the spindle D is retracted
from the socket E the first projectile falls into the extension Y₁ and the others
are held back by the lever Z. Upon the release of the lever Q the spring S
drives the spindle D suddenly forward, catching the first projectile between the
socket E and the spindle and imbedding the corrugations in the end of the spindle
into the projectile to turn the same, the inclines C force the spindle forward by
engaging the pin D₁ and thus prevent slipping of the corrugations on the pro-
jectile. The yoke K now raises the lever Z and permits the projectiles to move
forward to the end of the tube as before. Simultaneously with the forward
movement of the spindle the rod 26 moves in the same direction and the inclined
flange 39 runs under the lug 28 and raises the arm 41 into engagement with
the shoulder 42; this throws the carriage out of engagement with the thread
on the shaft G and allows it to run back to starting position. The carriage then
strikes against the latch 25 and releases the end of the arm 41 which arm drops
to the shoulder 43 and the spring 44 re-engages the half-nut of the carriage U
with the thread on the shaft G. This movement also brings the end of the
twine which projects from the beak 17 within the rear groove of the projectile
and at the same time the shoulder 36 releases the dog 5 and allows the hammer X
to fall and the cupped end of the head 6 strikes the metal down over the twine
and secures the same firmly within said groove. During the first revolution the
beak turns on its pivot and thus the twine is laid once round within the groove
of the projectile. The thread tool 13 traverses in advance of the twine and cuts
a spiral groove for the same and as it reaches the forward groove said tool is
drawn back by the lever 11. The flange on the projectile also keeps the twine
from winding beyond the groove until it is properly laid therein. The lug 7 now
slips over the angle of the plate 8 and allows the hammer W to fall, the tool 14
severing the twine at the proper distance from the end of the beak and the
inclined chisel face 16 turning a portion of the flange on the projectile down upon
the end of the twine wound on the projectile and securing the same. The crank
pin M imparts an intermittent motion to the wheel N as said pin engages the
recesses in the rim of the same, which recesses are of such number that the stud P
comes round and engages the incline Q₁ soon after the twine is severed and
fastened as described. This lifts the outer end of the lever Q and retracts the
spindle D thus releasing the projectile which falls into and escapes through
the tube 24. The wheel N stops in this position during the major portion of a
revolution of the shaft, which gives time for the projectile to get fully out of the
way of the next one before the latter is driven forward by the spindle upon the
next movement of said wheel. The rod 26 simultaneously moves in the same
direction as the spindle, the inclined flange 39 being highest at the rear now
runs over the lug 28 and raises the plate 27. As the carriage moves forward the
hook 3 engages the lug 4 and raises the hammer X which is then held by the
dog 5 while the carriage returns to starting position, being released as heretofore
described.
