OF WILMINGTON, DELAWARE, A CORPORATION MACHINE FOR PACKING NITROGLYCERIN COMPOUNDS INTO SHELLS.
Be it known that I, HOWARD A. STrpL- WELL, a citizen of the Unit d States, residing at Woodbury, county of Gloucester, and
State of New Jersey, have invented a new and useful Improvement in Machines for Packing Nitroglycerin Compounds into Shells, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a art of this specification.
. Vith this character of explosives the packing is performed by vertically movable rods or tamps. As the explosive is highly explosive, it is quite essential that the tamping rod corresponding to the shell shall go out of action as soon as the shell is .filled, and that friction be removed from tamp when not in use, to prevent heating and wearing of both the tainp and the frame, by which it is operated.
In practice there are provided'tamps or rods equalin number to the shells, and the present invention relates to mechanism for automatically rendering any and all of these tamps or rods inoperative as soon as its ing friction from said tamp.
in the claims.
'- .I will first describe theembodiment of my invention as illustrated in the accompanying drawings and then point out the'invention In the drawings:F igure 1 is a front view partly-broken of my improved ma.- chine. Fig. 2 is a section on line 2-2, Fig.

bare the tamps or packing rods equal in number tothe shells to be packed. 0 is the frame for reciprocating these 'tamps or rods. This frame 0 is reciprocated in the following manner. d is a driving pulley on shaft 6, on which is the gear f meshing with the gear 9 on the shaft It. On the opposite side of the apparatus and on shaft h is a gear 2,
"corresponding to gear 9 and which meshes with gear k, k are eccentrics, one on each side of the machine on, respectively, gears g and 2', and connected by straps or-loose connections respectively. with each' side or end of frame c.v Each rod or tamp 6 passes through an orifice in the frame. The frame Specification of Letters Patent.

0 is practically a skeleton frame. -Correthrough which extend the pins m, on each of which is a spring n confined respectively between a head 0 and the end wall of respective projections. p and q are reverse wedges, the surface of wedge g contacting with head 0. The wedge 32 has theextension 1' at its upper end and the extension 3 at its lower end. a is an orifice in the main frame through which the tamps b loosely pass. is a piece slidably mounted upon the main frame and having the projection w-movable into and out of alinement with the extension .9 of wedge p. This piece *2) has also a projection a; in line of movement of the projection y'inounted on the rock shaft 2. When the rock shaft 2 is moved in one direction the projection moves the slide :1) to the posiextension 8 of wedge 10. The rock shaft 2 a extends across the apparatus and is common to all the tamps or rods 6. The rock shaft is operated in one direction to move the slide 30 to the position shown in F by means of compressed air admitted by the operator to the cylinder 2, the piston rod operating the lever centrally, one end mounted on the rock shaft and the spring 1 being connected to the other end. 4 is acatchv pivoted centrally to the main frame.
One end, in the position shown, 1n Fig. 3, contacts with the locking pin 5 on the slide '0. A spring 6 on the opposite side of the pivot connects the bracket and catch. The end of the catch 4 on this side of the pivot is in line with the trip 7 mounted on the tamp b. This trip 7 has the upper operative end portion 8 and the lower operative portion 9. The contact between the frame 0 and the rodsor tamps b,
with the wedges p and g in the posltion shown in Fig. 3, is such as to cause the corresponding rod or tamp to move with. the frame. 0 butthe ramp or rod 5 can move vertically through the frame a as the shellis filling.
With the parts in the position shown in, i
Fig. 3, when a shell becomes filled to such an extent as to cause the rod or tamp to rise to such an extent that the lower operative portion 9 strikes the end of catch 4, it moves on its pivot against the action of spring 6. The slide a being released, it is thrown forward by the spring 10 and its forward end moves under the projection '8 as shown in Fig. 2 ;'thus locking the tamp b and rendering it inoperative. By the forward movement of v the projection w has been brought v into alinement with the end 8 of wedge p and drives wedge p upward on the next -downward movement of frame 0. This forcesthe piece q backward againstthe collar 0 on the pin on. and withdraws the pin m from contact with the friction piece Z, thus removing the friction from the tamp I) while.
it is not in use, the sliding piece a prevent 'ing the tamp from falling. Each tamp is thus locked and the friction removed until all the shells have been filled. When a new set of shells are in place, air is admitted to the cylinder 16 and the swinging bar 15 on the shaft 14 is swun into line with the end' r of the wedge as s own in Fi 2. At the same time a1r'1s admitted to cy inder 2 andthe bar 2 is rotated to withdraw the pieces '0 simultaneously by means of projections y and w. This allows all the tamps to drop downward upon the dynamite .in the hopper of the machine. ment of the frame a the wedges p are simul taneously driven downward, relative to c, by
the bar-l5, andthe' pin m being thrown forward by the springs 11. brings the friction.v pieces Zinto contact with the tam s which thus on the downward movement 0 frame a force the dynamite into the shells. The air has been in the meantime exhausted from the cylinders2 and 16, and z and15 have resumed their inoperative positions.
The object of the mechanism is to remove friction from the tamps while inoperative, and to allow said tamps to be dropped through the frame upon the dynamite in the hopper.

what I claim and desire to protect by Letters Patent is: I 1
