C. TRUYTER, OF WEST TO NORDLINGER, CHARLTON Y., A CORPORATION OF NEW MACHINE FOR MAKiNG FUSES;

SPECItICATONf forming part of Letters Patent No. 757,580, dated April 19, 1904. Application tiled February 11, 1902. Serial No. 93,509. (No modeL Be it known that we, GEORGE LISPENARD, residing at the city of New York, borough of Brooklyn, county of Kings, (and whose postofiice address is 585 Bainbridge street, in said borough of Brooklyn.) and EDWARD C. TRUY- Tau, residing at Test New Brighton, county i" Richmond, State of New York, (and whose post-office address is I'ioughwont avenue, in said Nest New Brighton.) both citizens of the United States, have invented certain new and useful improvements in Machines for Making Fusespf which the following is a specification. The object of our invention is to provide a ttfnine for the economic manufacture of )s for explosives. it consists of a mechanism for making the iniiammable material into a cylindrical shape, means for forming the fuse into a compacty body, and a mechanism for feeding the element forming the fuse through the binding device und reeling the fuse out of the machine.

Our invention is illustrated in the accompanying drawings, in which the same refcrcnceletters indicate similaiparts in all the figures.

Figure l illustrates a side view of the machine. Fig. Q illustrates the top View. Fig. 2% illustrates a vertical section of the feeding device. taken on the line 3 3 of Fig. 4. Fig. J, illustrates a rear View of the feeding device. li'ig. illustrates the folding means for the wrapper of the fuse. Fig. 6 is a rcarview of the folding means. Fig. 7 illustrates a perspective View of the feeding-trough, and Fig. o illustrates a cross-section of the fuse.

ln Fig. i, A indicates the base of the machine. to which are fastened the bracket a and the framework 142, which consists` preferably, of a rib extending from the bracket a3 transversely across the base A to approximately the center thereof and from there longitudinull) of the base nearly to the end thereof, and provided ai proper points with suitable supports as may be needed for the various parts The bracket a/ supports a hopper B for the fuse material, which may i .folded about Lthe cord 21.

be gunpowder or other pulverulent matter. The hopper is supported on a neck 6, in which is a vertical conical-shaped opening b3, through which pass the iniammable material 62 and 50 the central cord b4 of the fuse. This central cord Z gives a body for the fuse in its process of manufacture and aifordsa means of readily handling the fuse without breaking it. The cord b is fed offA from a reel. (Not shown in the drawings.)

Below the hopper is supported the horizontal feeding-trough C, aving a ring c' for guiding the cord b4 into the feedingetrough C. This ring c is supported in a groove es. At the other end of the feeding-trough is l0- cated the head c2, by which the feeding-trough is supported in the bracket a'. The trough has a channel c4 and at one end a segmental annular opening c5.

From the reelD a ribbon J, of paper or other material, is guided over tension-roller (Z3 and into the feeding-.trough C through the opening The shape of the opening c5 gives the ribbon d the shape of the channel 0*. The 70 inflammable material 62 falling from the hopper is caught bythe ribbon and, together with the cord 5, is drawn through the folding device E.

The folding device E is fastened to the lower end of the hopper, and" comprises an arm which is curved downwardly and outwardly, so that its lower portion is parallel to the axis ofthe feeding-trough and extends in the direction that the fuse moves through said trough. This lower portion is provided with a cylindrical opening e', tlnouglrwhich the inflammable material is fed, and a slot e3.

, This portion is also provided with a yoke @2,

against which the feeding-trough is pressed '85 in order to position the feeding-trough propcrly relative to the hopper. The ribbon in passing through the cylindrical opening e' is the inflammable material 62 and Froml the. folding end of thc 9o folder E the elements of the fuse pass through the conical opening c", which further brings is driven by a pulley F,

the fuse into a compact body. From the feeding-trough C the machine.

rIhe binding-machine (illustrated in Fig. 2)

mounted on a transverse shaft the outer end of which is supported in the bearing f of the support (0,3. On the shaft a* is also mounted a bevel-gear f, adapt-ed to mesh with and operate twosimilar bevel-gears]c2 and f, which are mounted on the ends of a longitudinally-arranged shaft supported in a bearing ff, carried upon a suitable support rising from the rib a2. The bearing 7"Ji is provided at its side toward the bevel-gear f with a lug fx, in which the inner end of the transverse shaft is journaled. To each of the gears f2 f3 are attached frames ',f, which carry spools f on spindles f 7"., passing through the center of the spools and journaled at their lower ends in suitable bearings f on the frames f5. Springs f7 are pivotally supported on the headed lugs f8 on the frames f", their free ends pressing against the spindles f7, thus holding them in place against their bearings f, except when removed to release the spools f or whent the spools are replaced. The removal of springs f8 from contact is easily accomplished by revolving said springs half a turn on the lugs f8. An additional function of the springs f8 is to prevent any undue movement of the spindles while the machine is in operation. Also attached to the frames f5 E' are arms f9 f, which form guides for the fuse and also for the thread which is fed from the spools f f through the holes f1 in the guiding-arms.l The fuse is drawn through the first guide-arm f, and at the .same time the spools about the fuse in one direction, thereby winding the fuse. As the fuse passes through the bearing ft and the guide-arm f of the frame fastened to the gear f3 the l fuse passes .to a bindingl the l with the spindles o 'gear f2 revolvesthel thread fed from the spools of that frame' winds the fuse in the opposite direction, thereby binding the fuse' into a compact body.

' The yfuse is then reeled by a reeling mechanism.

The reeling mechanism consists of a gear (J` r,'fastened to the gear f2, which is turned by the' gear f. A gear g' meshes with the gear G. The gear g is fastened to a shaft g, which is supported in bearings-g2 g2, rising from the base A, and the rib co2. At one end of the shaft g3 areflocated the endless screws g4 g5, which mesh with the worm-'wheels g g mounted upon transverse shafts gE g", which are carried by bearings g1o g, suitably supported from the rib a2?" On the .shafts g8 g9 are also mounted wheels g12 gw, provided with, grooves gM on their surfaes. The fuse d? is wound around the wheels g12 g13 in their grooves g, and then4 it is passed down to thel reel.

By the means linst described the fuse d is fuse into a more compact mass, and

`ing a strip of paper grooved wheelv 11.2, which given the proper through the machine is given a uniform rate.

For operating the reel a grooved wheel H is attached to the shaft g8. A belt 7L' plays somewhat loosely over the wheel H and the is fastened to the reel. The belt la is thus permitted to slip as the fuse-reel becomes filled with the windings of the fuse.

The mechanism above described for making a compact fuse. may be varied without departing from the spirit of our invention.
