IMP'RovEMnNT IN MACHINES PQR PACKING SALT.

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom yit may concern y t Be it known that I, JOHN MoG'nnw, of West Columbia, in the county of Mason andState of West Virginia, have invented a.ne\v and .improved Machine for Packing Salt; andI do hereby declare that the following isa full, clear, and exact description of the same, reference being had to the accompany-` ing drawing forming'a-part of this specification, iu

which- Figure l is a side elevation, with one side of the base-chamber removed 5. v

Figure2 is a transverse vertical section; and

Figure 3 is ai plan view of the lower ends of the filling-tubes and packing-hammers.

. This invention has for itsohject the filling of bar- -rels with salt at the place of the manufacture of the same.

vThe,iuventim consists iuhammers xed at the Alower ends offvertical rods, whose upper ends are connected, bya pitman, with a horizontal crank-shaft Y mounted in a frame thatslides in a vertical guideway, the revolution of the crank operating the packing-hammers, and the sliding frame yielding against the pressure of the hammers upon the salt, so astolift the hammer-maud keep them always ,aboveV the surface of the salt in the barrel, as the latter graduf ally fills.

Also, in providing the packing-hammers with wedge-shaped projections, for packing salt into the bulges of barrels.

Also, in' 'combining with the packing-hammers,

vtubes for conducting salt into the barrel, and vertically adjustable, in order `that they may be set higher or lower, with reference to the salt' in the barrel, according as more or less salt is to be delivered'at each rise of the packing apparatus and in combining, with the packing-hammers vand filling-tubes, a.- rotating table for the barrel to stand on, so that the latter may b e turned as it lls, in order to insure a` packing of uniform density.

AIn the drawing- A is a horizontalA chamber. Y

jt, a conveyer screw, which conducts salt, within the chamber, from the feeding-,funnel i to thervertical elevator k.

d d are the inclined branches of aspout, which re-r ceive the salt from the elevator and conduct it to spouts c c, one at each side of the verticalframe-work B, by which spouts the salt is led throughadjustable lilling-tnbes b b into the barrel.

The filling-tubes are attached to a head, whhh,v is rigidly conuected,by stays m, with the frame 11, which .slides `in vertical guide-ways in the frame-work B.

The filling-tubes are quadrantal in shape, and

placed opposite each other, and between them slide the packingdlammers c o, also placed opposite each other, and affixed to the lower extremities of vertical rods r r, which pass through the head, and are provided with cross-heads at their upper extremities, which slide in vertical guide-ways within the frame u,

Vand are connected, by pitmen s s, with a crank-shaft, t,

placed horizontally ofthe frame n, passing through slots in the sides of the framework B, and made to revolve bythe application of any suitable power, so as to impart to the hammers'the,reciprocating motion requisite to packingsalt in the barrel.

By means of pinions 'u on horizontal shafts e, at

the sides of the frame-work B, gearing with racks w i ou the frame n?, the latter` may be set so as tolocatc thek illingtubesaud packing-hammers at the required height 'within the barrel. This need only be done at the beginning of` the operation of filling a barrel, as, during they operation, the frame adjusts itself.

The filling-tubes should be placed so that the packing-hammers pass below their lower ends, and they are adjustable, for this purpose, on the head.

The barrel isv placed on a table, c,'that is let into the top of the base-chamber'A, audlafxedto thc upper end of -a vertical shaft, sc, Awithin the base-v chamber, which receives rotation through the 'instrumentality of bevel-gearing, which is operated by' a stem from the conveyer screw, so that the barrel turns as it is filling, and every particle of the packed salt receives a uniform pressure.

Every time one of the packing-hammers descends, aud meets with resistance from the salt it cozn- -presses beneath it, it rises a little, lifting the frame at in its guide-way. 'lhe frame'n. carries up with it the llling-tubes.

A-t every elevation of the filling-tuhes a fresh deposit of salt is left behind in the barrel, which, by the revolution of the latter, is speedily brought beneath one of the hammers and compressed. In this Inauner the hammers gradually travel upward till the bai'- rel is fullQ- It is obvious that the weight ofthe frame u determines the degree of density with whichthe salt is IVhztt I claim ns new, and desire to secure by Letters Patent, -is- 1. The packing-hammer o, combined with the slidingr head o1, substantially in the manner described, and for the purpose of enabling the hammers to lift themselves in the barrel, while packing salt therein.

2. The packing-hammers, when provided with wedge-shaped projections a, at their outer und lower corners,.for the purpose of forcing salt outward into the bulge of the barrel, substantially as specified.

3. In combination with the packing-hammers, the

adjustable filling-tubes b, substantially in the manner and for the object specified.

4. In combination with the packing-hammers and filling-tubes, the rotating table c, substantially in the manner and for the purpose set forth. y

To the above specilicntion of' my invention I have signed my hand this 25th day-ot' Merch, 1870.

JOHN MCGREW.
