SIDECIFICATIN forming part or Letters Patent No; 311,824-, dated February 3, 1885.

Application filed December 13, i584. (No model.)

T0 @ZZ whom it may concern:

Be it known that I, XV. S. FORD, a citizen of the United Sta-tes, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Presses; and I do declare the following to be a full, clear, and exact deseription of the invention, such as will en` able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a side View of my device. Fig. 2 is an end view of the same. Figs. 3, 4, 5, 6, 7, and 8 are detail views. Fig. 9 is also a side view. Fig. 10 is an end View; and Figs. ll, 12, 13, 14:, and 15 are detail views.

rIhe invention relates to presses for tobacco, cotton, and similar fibrous substances, and has for its object the construction of such a press, which,while capable of doing more eiticient work thanv those in ordinary use, may be cheap, simple, strong, and easily taken apart for transportation and set up for use.

The invention consists in constructing and arranging the parts in the manner hereinafter described.

In the accompanying drawings, A represents the head-block of the press, made pret'- erably of seasoned timber, and composed of the two equal and similar beams a a, lying side by side, and secured together at each end by a rectangular metallic band, hereinafter more fully described, the ends of the beams c being rabbeted to receive the band. The pieces c a are kept a suitable distance apart, and are tightened in their end beams by having properly-shaped similar wedges, a a', inserted or driven between them at equal distances from each end and'near the end bands.

B is a block of cast metal, fixed centrally to the lower surface of the head-block by means of an upward extension which ts and is properly secured in opposite recesses inthe beams a a. This block is internally threaded centrally, for a purpose hereinafter explained. rIhe block B is provided with :danges to engage the lower surfaces of the beams c c, and `assist in keeping the block in place, and also with dovetailed lugs, which engage the outer sides of said beams and aid in preventing the block from falling downward.

C C are similar retaining-rods passing vertically between the beams a a, in opposite recesses in the same, and at equal distances on each side of the block B. The function ot' these rods is hereinafter explained.

D D are the rectangular end bands which bind the beams a a together. rFliese bands have on the upper and lower corners of each side the lugs d (l, internally threaded to accommodate the threaded upper ends of the rods which bind the head-block to the base of the press, instead of using the bands D. The ends of the beams a may be left square as they come from the mill, and properlyshaped cast-iron plates D may be placed on top and below their ends, the upper one having side lugs which clasp the outside of the beams, as shown. The rods F pass through the extended edges of said plates, and the lower one is secured to the beams c a by the bolts d. These bolts are alone sufficient to keep the beams c apart. By means ofY these lugs and proper nuts, d cl, the said rods are secured to the head-block and are rendered slightly adjustable in a vertical direction thereon..

E is the base or bed-plate of the press, made preferably of seasoned timber, and composed of the side beams, e e, lying parallel to the beams a a, and bound together by proper cross-beams,and a central platform, c2, raised somewhat above the level of the beams, to receive the bottom of the packing hogshead or cask, and prevent the chines of the same from being broken by coming into contact withany part of the base, the platform lying within the chines. rIhe outward-extending ends of the beams e e are rounded for the purpose of being inserted into the ring-shaped lower ends ofthe connecting-rods F.

F F, Ste., are four connecting-rods having their upper ends threaded to engage the lugs d of the bands D, and their lower ends, ff, made ring-shaped to iit over and turn on the roundedends ofthe beams e c. By this construction the said connecting-rods maybe detached from the beam c on one side, and the head-block may be turned, when desirable, outward tothe other side, the connecting-rod IOO on the latter side rotating on the beam e, to,

which they are attached.

G is the hogshead, barrel, or cask into packed under the follower fromv that side.

which ythe material is to be packed- The said receptacle stands upon the platform ce', as described. f

I-I is a stout screw,made of cast metal, and passing through and engaging the internal thread of the cast-metal block B. ,'Ihe upper end of the screw is madeinto or has fixed upon it the transverse socket l1, into which lits the end of the lever h', by which thescrew is actuated. In practice the sockets extend to both sides, so as to accommodate the vopposite levers, as shown. The screw is made short, so that the levers may not be out of reach when it is elevated to full height. The lower end of the screw is rounded, and sets against a properlyshaped` metallic socket, h2, which rests or is fixed upon the follower or packingbars when the press is in action. The point of the screw is chilled, case-hardened, or made of steel to prevent rapid wear, and works'in a chilled socket, and the screw is made hollow, so as to give it lightness while retaining sufficient strength.

I is the follower,wl1ich rests directly upon the material which is to be packed, and t' c' are tiers of packing-bars lying in ascending pairs, each pair being transverse to the one immediately below.

t" is a single central bar lying across the highest tier, and carrying lthe socket h2, as shown.

J J are similar eccentric cams, having their pivot points orjournals cast upon them, and rotating in the space between the beams a co, in proper recesses in which the said journals turn. rIhe said cams have each a depending arm, j, and each is situated immediately to Ithe outer side of one of the retaining-rods C,

with its edge bearinglightly against the same, so that when the rod attempts to ascend the cam turns and binds against it and stops its motion.

j brings the cam into normal position. Sometimes it is desirable to use a rectangular packthe lower end of the cam resting Within and l,between proper retaining-slips secured to the 'y upper surface of the base, as shown in the drawings.

Ihe method of packing is as follows: As the screw is driven down ythe retaining-rods C 'accompany it, sliding freely in the recessesor channels in the head block; but when the screw is elevated and the swelling or recoil of the pressed material attempts to force the Ietainingrods upward the cams are turned against them and hold them down, the bearing between the two being sufficient for this purpose. The retaining-rod on one side is then raised by hand, its cam being pulled and 4 held down, and the material inserted and When released from the rod,the arm The screw isthen again brought to act and the material vagain pressed, the next packing being done on the opposite side from the rst.

When desirable, as in puttingin the rst part ofthe material, the connecting-rods on one side may be detached from the base and the head block rotated to the other side. This gives more room. The rounded ends of the beams e e are generally tapered, so as to allow the ring-like ends of the connecting-rods to be easily tted over them.

The advantages of the invention are, that the press can be cheaply made, can exert powerful force, is compact and comparatively light, can be-knocked down for` transportation very quickly, occupying little space when packed, and can be quickly set up and adjusted for operation.

Having thus described my invention, what I desire to secure by Letters Patent is- 1. A press for tobacco or other material, composed of a head-block having properly fixed thereto a cast-metal block provided with an internally threaded vertical opening, a cast-metal operating-screw engaging the opening in said block, a base-piece of' proper construction, and rods or bars suitably constructed and arranged to connect and rmly bind together the said head-block and base-piece,

3. In a press for tobacco or other material, the combination of the head-block A, composed of the side beams, a a, united at their ends by the bands or straps D, the wedges c a', and the metallic block B, with a properlyconstructed base-piece provided with a central platform having an elevation above the rest of the base, and rods or bars connecting IOO IIO
