SPECIFICATION forming part of Letters Patent No..'731,735, dated June 23, 1903. Application filed February 24, Serial No. 95,404. (No model.)

Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Presses, of which the following is aspecication.

The present invention is in the nature of animprovement on the press shown and claimed in my former patent, No. 643,354,4

dated April 10, 1900, and is a carryingifor` ward of the ideas set forth in said patent,- toi gether with the addition thereto of certain.V distinctly novel and valuable features. `Referring to the accompanying drawings,

it will be seenthat the bed or foundation of the press. is preferably composed of two I- support suitable driving mechanism for the main shaft. Said driving mechanism comprises a driving-shaft E, having a clutch-pulley F secured thereto and adapted when thrown into operative relation through movement of hand-lever G and suitable connections to impart motion to a shaft H. Said shaft through suitable gearing, (not shown,) which is inclosed in housings or casings I, imparts a rotary motion to the main drivingshaft .l of the press. The forward end of the shaft has its bearing in the head or frame B, while the opposite end hasits bearing in a removable head or bushing K, bolted in the frame C and from which it may be readily removed. Upon the outer end of the shaft there are mounted heavy washers'or rings L, M, and N, the intermediate member being preferably formed of brass, while the outer members are of steel. The washers are held in place by nuts O P, screwed upon the shaft, and the inner ring M is held against i rotation by a pin Q, Fig. 3, which extends through it and into the removable head or bushing K. The outer washer N is keyed to the shaft and rotates therewith. inasmuch as the strain which is exerted upon the shaft when the press is in action is toward the head of the machine, the construction just described forms, in effect, a thrust-bearing. Positioning the brass washer between the steel ones affords a bearing simple in construction,

but effective under Working conditions, and

presents the advantagesresulting from av brass surface working against a steel one.

Extending out from head or frame B is a stub R, and secured between said head and the intermediate frame D is a rod or shaft S,

hereinafter referred to as the hinge shaft or rod.

Hopper Tis formed with lugs or earsU and V upon its sides, lug U passing over and being secured to stub R and the other ear or lug V embracing the hinge-shaft. A capscrew W also extends through head Band helps to'keep the hopper in place.

The outer shell'of the press proper is composed of two parts, an upper-.and a lower section, both of which are pivotally connected to the hinge-rod S, so that theymay be swung open and access had to the interior of the press when desired.

The construction of the sections will de ICO pend upon the nature of the material to be treated, andV under certain conditions they may be made similar to many ofthe perforate shaped ribs or arms, the outer ones 0L and cen` tral one b being formed with an opening or slot c, extending from the outer to the inner face thereof, while the intermediate arms d are solid. Each arm is formed atits free end with a lug or finger e for a purpose which will presently appear. Two series of barsf are secured to the ribs or arms against theL nner faces thereof, one series being secured between each of the outer ribs a and the central rib b, so that the spacing between the various sets of bars may be varied throughont the length of the press. Each of the bars fis provided with an opening at its outer end, through which a bolt gis passed, said bolt passing up through the slot in t-he rib a and being secured thereto by a nut and washer, which spans the slot and rests on'the upper or outer face of the rib. The inner end of each bar is reduced, as in Figs. 13 and 14, and rests upon a plate h, which lies flush with the inner faces of the various bars, said plate being held in place by bolts ft', which pass up through slot c in ribs b, suitable nuts and Washers securing said bolts in position. From this it will be seen that each set of bars upon opposite sides of t-he central rib b may be adjusted independently of the other and the spacing of each set varied as desired.

In order that the bars may be readily and evenly spaced as they are assembled, I propose to form a seat ordepression in the outer face of each bar and to pass about the bar a strip j, of copper orlike metal, as shown in Figs. 8, 9, and l0, the ends of the strip being forced down into the seat, thereby holding the strip against displacement. As will be readily understood and as will be seen upon reference to Figs. 9 and 10, the bars can come only so close together as the strips will permit, a close spacing being effected in Fig. 9 and a wider one in Fig. l0. By varying the gage of the copper or metal employed the spacing may be regulated to a nicety. The

strips, as will be seen upon an inspection of Fig. 8, are narrow. Cpnsequently practically the entire length of each bar is left unobstructed. In order to secure the ribs in proper position with relation to each other, to hold them in position when the bars are being removed or replaced, and to -give stability to the structure, bars k, extending the of the press, is loosely mounted on the bolts and is held in place by nuts r.

Blocks s are cast upon the headblock B and the intermediate frame or section D, and hooks t, pivotally connected to stubs extending outvtherefrom, engage bar m when, the.

lower or bottom section ofthe shell is swung up and serve to hold said section in place. After the parts are in place buttons u serve to lock the hooks against movement. When the top section is lowered or if it has been previously lowered, bar q is swung up over the lugs or arms e, passing over the top of the same, after which the nuts r are screwed down, firmly holding all the parts together.

When it is desired to open the shell or casing,thereverseoperationtakes place. Swinging bar q rotates shaft m, and said shaft by reason ot' the formation of the hooks t rolls out of engagement with the hooks, throwing the same outwardly, fthereby permitting the lower section to be readily dropped down. The hooks, however, will normally stand in a position to engage the shaft when the lower section is elevated. As will be seen upon reference more particularly to Figs. 1, 2, and 3, the shell or casing makes a close tit with the hopper, as well as with the adjacent face of theintermediate frame or section D. Said section D is, as shown in Fig. 3, formed with an opening of the same size as and in line with the interior of the shell. y

Shaft J, except for those portions which work in the bearings, is polygonal in cross- IOO IOS

section, and mounted thereon within the shell is a series of separated screws A'. The particular arrangement of the screws is not essential, though for some materials the arrangement shown and claimed in my aforesaid patent is advantageous. lt is not essential, however, to the operation of the press on all materials that such lrelation obtain, as the screws may be set in opposition to each other, and certain features of the presssuch, for instance, as the formation of the shell-may be advantageously used with a press employing a continuous screw.

Where the separated screws are employed, thimbles B will be placed intermediate the same as they are slipped onto the shaft.

A split sleeve or pipe C', perforated throughout a portion of its length, surrounds shaft J and is connected to the outermost screw-section by pins C2, which enter slots or elongated openings C3, formed in the shell-sections. The slots permit the sleeve to be dinally thereon. Y

The

shell is likewise provided with a series of` openings I in its side wall. A hollow annular collar .I' encircles the shell at this point,

said collar being provided with a discharge-4 orifice K and aninlet L for flushing this portion of the apparatus when desired. The collar remains stationary, while the shell rotates.

A collar M is splined to the shaft in rear ofthe shell, and rods N', connected to said collar, extend forwardly and have their ends seated in sockets formed in the shell G. A

tation of the shaft, eventually cutting the copper strips above referred to and closing conditions it maybe found expedient to omit -the disintegrating-pins II' from the shell.

- fedinto the hopper, and the operator orat-` tendant throws the friction-clutch into oper-` ation through manipulation of lever G. R0-` tary motion is thereupon imparted to shaft The operation of the press is as follows:`

The shell or casing being closed, material is J, the screws, the draining-tube C', and shell G', collar J remaining stationary. The material is then carried along by the first or Under some feed screw, as it may be termed, and forced into the space between it and the nextscrew, whereit is compacted or pressed to a considerable extent, the liquid matter passing out `through the openings in the shell. When the material in this portion of the press is compacted to a certain degree, it is taken up by the next screw in the series and again compacted or pressed into the next space. The material between the screw-sections does not rotate, and it is owing to this that the press is eective. The material is thus carried along until it reaches the discharge end of the press, where it is acted upon by the disintegratingpins carried by the rotary shell G'. This shell forms in effect what may be termed a head or plug and serves to retard to a certain extent the too-rapid egress ordischarge of the material, thereby permitting the last screw-section to eifect a compression of the material. The extent of opening between the head or shell and the discharge end of the press will depend upon the nature of the material under treatment and will be regulated by the attendant through manipulation of the hand-wheels P and Q. Any liquid which may be forced out of the material by the last screw will pass out through the openings in the shell of the pressand into the draining tube or pipe C. That portion which passes into the tube finds its way into shell G', thence to collar J" and into the discharge-` pipe K', which of course will be connected to a flexible pipe to convey the extracted liquid to any suitable point, thus keeping the discharge end of the press adjacent to the operators stand dry. The shell or hollow head may be flushed when desired.

When it is desired to open the shell or cas- Pins F2 serve to limit the rearward move` ing of the press, nuts r are loosened and bar q withdrawn from engagement with the lugs c of the upper section, when said section may be thrown back, as indicated in Fig. 5. By a further outward movement of bar q after the latches u are turned back shaft m is rotated in its bearing in hooks t, which rotary movement,owing to the curvature of the seats in the hooks t, causes said hooks to swing outwardly, freeing shaft m and permitting the lower section to be dropped down. The reengagement of the parts will be readily understood from the foregoing.

By the employment of the removable head or bushing K and making the head G', collar J', and wheel O' longitudinally separable, so that they may be removed from the shaft, the screws may be readily withdrawn from the shaft through the opening in the frame C. This does away with the necessity of taking down the press when for any reason it is desired to remove the screws or the shaft itself.

Instead of making the forward face of the follower substantially fiat it may be given a conical form.
