*iM-PROVEMENT 'iNCEN'i-RIFUGAL MACHINES.
. Specification forming part of LettersPatent 52,569, dated February 13, 1866. n
To all whom t't may concern: l
Be it known that we, G. B. HARTsON and E. J. WOOLSEY, of the city, county, and State of New York, have invented certain new and useful Improvements in Apparatus for Separating 'the Liquid Parts from Sugar or other Substances 5` and we` do hereby decla-re that the following isa full, clear, and exact de scription of the saine, reference being had to the accompanying drawings, making part of "this specilication, in which Figure l is a plan of the apparatus. Fig. 2 is an elevation of the revolving cylinder or separator, the .external fan which receives the liquid parts 'after they are separated being omitted. Fig. 3 is avertical section of the apparatus taken through thecenter.
The saine letters indicate likeparts in all the figures. 4
In the apparatus for depui-ating sugar or' separating liquid from solid substances by cen-,- trifugal action great velocity is required, and if, 'as is frequently the case, the material t0 be depurated or deprived of liquid matterbe not in weight equally distributed around the center of-motion. and at equal distances from the axis, (which is often inipra'cticable,) a treninlous motion is inducedwhich increases with the increased velocity and exerts an injuriousaction, which in la'I short time destroys the. mechanism, however strong the structure may ``lleretofore the vessel or separator contain; ing the material to be acted upon has been mounted on a. shaft with journals at each end,
and connected with the said shaft by means of arms, the pulley for receiving the driving-belt being mounted on the shaft, and necessarily` at some distance from both journals. As the belt must of necessity be tight, this tension draws and slightly bends thev shaft, which ofA itself carries the weight in rotation out ofequilibriuln and produces theinjurious'tremulous nio:4 tion above referred to. Y
The first part of our invention relates to a mode of constructing and mounting the sepa..-
, rator with the View to retain the rotating post of the apparatus in a true central position, vand at the same time to prevent the centrifulgal force acting on the unequally distributed weight from producing the injurious tremulous motion above referred to; and tothis end, this part of 'our invention consists inv construcb ing the separator which isto contain the lsaccharine matter to be depnrated orother matter to b e acted upon on alstrong horizontal plate, having a hollow centered hub fitted to;
rest and turn on a strong stud attached to or making part of a base-plate, the said hub bef' ingprovided with a pulley near toan-d below v the bottom plate of the separator to. receive the drivingbelt. In this way alltendency to vibration4 is avoided, for any tendency to bend the .stud .on which the hollow hub turns will not shift the apparatus o-r any portion of it relative] y' to the axis of rotation.
Prior to the invention of this improvement it was common to make these machines with a centra-1 shaft rising from the base of the machine to a journal-box ixed in stout beams or frame-work in'or upon the ceiling of the apartment in which it was placed, and the driving belt was arranged on a pulley above the machine. This central shaft prevented conven'- ,ient access to Atheinterior of the machine, and
involved much expense in the construction -ot' the upper journals and the security of the -upper end of the shaft. The use ofthe shaft,
owing to its great weight, also required increased power to drive the machiue,^with increased expense or fuel; and also rendered the machine cumbersomefor transportation, and incapable of out-'door work unless a strong cross-frame and braceszwere erected over 'the machine in which to place the said upper journal. Such frame greatly added to the expense of the machine, increased its bnlk,'and prevented convenient approach thereto by workmen and attendants.
All of .the above objections and difliculties. 'are overcome in our improvement. .We dispense with the rising central shaft, upper journal, frames', and braces, With all their inconveniences.. and .we greatly reduce the cost -of constructing the machine, as well as the 'ex- 'pense of driving it.
, The second part of our invention relates'to themethod of introducing a current or currents of air into the separator to aid inthe effeet to be produced on the substance undertreatmen't. Heretoforethe upper vpart of the separator has been made either entirely open, except the arms connecting 'the rim with the shaft, or entirely closed. This part of our in- Aon the substance or substances underA treatl scribe its construction and operation.
