PRESS IN PARTICULAR FOR SUGAR-CANE OR THE LIKE.
Specification of Letters Patent.
Patented Dec. 30, 1919.
Application filed December 28, 1918. Serial No. 268,730.
ing is a specification.
. This invention relates to improvements in presses especially though not necessarily designed for pressing sugar cane orthe like and is of the type comprising a pair of enclless chains composed of plates, said chains passing between rollers.
Primarily the invention has for its object to increase the extraction of the juice from thesugar cane or generally'of the liquid from liquid containing materials.
Efforts have been made to get rid of the systemof roller mills by using presses of the type referred to above. The known presses of this kind however do not allow of the appliance of the exceedingly high pressure which is necessary for the extrac tion of the juice from sugar cane or the like. Although such a high pressure surely can be attained in the. usual; roller mills, the latter have theinconvenience of exerting the high pressure only for very short periods 'of time, varying withperiods of less pressure, during which the extracted juice is again partially absorbed. This drawback is be ing avoided in the presses in which endless chains composed of plates are being used. The points however which according to the invention are regarded as very important and which were neglected in the known presses of thiskind are primarily the manner in which the endless chains are driven and secondly the way in which the pressure is applied to the chains. It goes without saying that the usual manner of driving the plates by means of a hexagon, octagon, dodecagon, over which the chain is being passed does not allow of exerting the high pressure required for completely squeezing out the juice from the sugar cane or the like.
According to the invention the pressure can be increased to its maximum without disturbing the continuous working of the press by providing the upper series of plates with toothed racks cooperating with toothed wheels mounted 011 the shaft of the pressure rollers and having pitch-circles, the diameter of whichis equal or almost equal to same of the pressure rollers.
This construct-ion guarantees a perfect transmission of power and enables to work with any available pressure on the material to be treated between the plates.
This and other features of the invention will be more fully described hereinafter with reference to the accompanying drawings, in which- Figure 1 is partially an elevation, par tially a longitudinal section of the press,
Fig. 2 is a cross-section on the line AB in Fig. 1 and Fig. 3 is partially a plan view, partially a horizontal section on the line CD-E of the press as shown in Fig. 1.
Fig. 4. is an enlar ed fragmentary longitudinal sectional detail of the roller and rimarrangement for coacting with the gears and rack and,
Fig. 5 1s an end elevational detail thereof partly in transverse section.
he palr of endless chains 1 and 200mposed of plates are arranged between a series of standards 3 and 4 and are passed over hexagons 5, arranged in pairs, one above the other, at both ends of the press and mounted on shafts 6, which are suitably .supported.
The chains 1 and 2 pass between a plurality of upper and lower shafts 7 and 8. which are supported in bearings formed in the standards 3 and 4. The upper shafts as well as the lower shafts are rotatably mounted.
The upper shafts are also capable of vertical adjustment; the top metals of these shafts are inclosed by steel caps 9 provided with hydraulic pressure means such as for instance hydraulic rams.
The upper shafts are provided with three toothed portions or wheels 10 meshing with toothed racks 11, attached to the plates of the upper chain 1. Pressure rollers 12 at both sides of the toothed portions 10 cooperate with running surfaces'or projecting rims 13 at both sides of the toothed racks.
v The diameter of the pressure rollers is equal are not exposed to the hydraulic pressure on the upper shafts. The pressure rollers 12 may be shrunk on the shaft.
The lower shafts are provided with enlarged portions 1s forming rollers, which support the plates of the lower endless chain 2.
Independently of the pressure applied to the upper shafts the upper endless chain is driven by means of the upper shafts, which to this end are provided with gear wheels 15 meshinq with gear wheels 16 on the lower shafts 8. The latter may be driven in any appropriate manner by a common motor one or more sets according to the material to be treated.
The plates of the lower endless chain :5 are perforated so that the juice squeezed out from the cane can ass through the perforations into a juice-nan 17, from which it ma be drained in any suitable manner.
A most striking adi 'antage of the pi. according to the invention is the fact ti motion is imparted to the endless chains by means of cooperating teeth in such a manner that considerable strains in the plate composed chains are avoided.
This construction furthermore has the ad vantage of allowing of the application of hydraulic pressure in presses in which endless plate composed chains are employed.
Hitherto this has been impossible owing to the fact that the propulsion of the chains by means of 'hexagons, octagons or the like is too imperfect and defective for the application of high hydraulic pressure.
In accordance with the art of the material to be treated the number of shafts and rollers and the length of the chains may be Having fully described my invention, what I claim and desire to secure by Letters Patent is:
1. In a press having coacting chains and relatively adjust-able shafts and provided with coacting racks and toothed wheels respectively mounted on the chains and on the adjustable shafts, the combination therewith, of bearing surfaces arranged on the inner surface of the chain in proximity to the adjustable shafts and positioned on opposite sides of the racks and pressure rollers mounted on the adjustable shafts and positioned on opposite sides of the toothed wheels for engagement with the bearing sun face and being of a diameter approximately equal to the pitch diameter of thetoothed wheels whereby to prevent grinding action between the wheels and racks when subjected to pressure. p In a press of the character described, in combination, supporting standards, upper andlower plate composed chains operating longitudinally between the standards, rota table transverse shafts arranged above and below the adjacent lower lay of the upper chain and the upper lay of the lower chain, vertical slidable bearings on the standards for receiving the upper shafts, longitudinally extending racks carried by the inner surfaces of the plates of the upper chain, toothed wheels carried by the upper'shafts and meshing with the racks, rims arranged on opposite sides of the racks andparallel thm'ewith,' pressure rollers carried by the upper shafts on opposite sides of the toothed wheels and bearing on the rims to prevent grinding action between the wheels and racks when subjected to pressure, and rollers carried by the lower shafts.
In testimony whereof I aflix my-signature.
