DUST RECEIVER FOR GHINDING AND POLISHING MACHINES.
APPLICATION FILED OCT. 16| 19l6.
.Patented Feb. 5, 1918.
riannonsn, or rniviv van, lvnvv nenn..
To all whom it may concern." f
Be it known that l, FRED Ronsn, a citizen of the United States of America, and res1\ dent of Penn Yan, in the county of Yates, in the State of New York, have invented new and' useful Improvements in Dust-Receivers for Grinding and Polishing Machines, of which the following, taken in con-y nection with the accompanying drawings, is
a'full, clear, and exact description.
This invention relates to certain improvements in dust receivers for grinding and polishing machines adapted to be used more particularl -in connection with small polish- -ing or bu ng wheels commonly employed by jewelers, Opticians and other craftsmen, and has for its object the removal and collection of dust and the line particles ofprecious metals which have considerable value. lln other words, ll have not only sought to remove the objectionable rouge dust which is more or less poisonous to the operator, but also to recover the small particles of gold and silver commonly thrown od by the polishing or buiiing wheel, and usually" very dicult to recover unless some special provision is made to accomplish this result.
Other objects and uses relating to specific parts of the device will be brought out in the following description.
lln the drawings* Figure l is a front elevation of a polishing device and my improved dust collector inoperative relation thereto.
Fig. 2 is an enlarged longitudinal vertical sectional viewl of the detached dust-collectin device shown in Fig. 1.
lig. 3 is a transverse vertical sectional view taken in the plane of line 3-3, Fig. 2.
Fig. il is a perspective view of theremovable tray inV the head of the dust collector.
Fig. 5 is an enlarged transverse sectional view through the dust-collecting conduit taken on line 5 5, Fig. 1.
Illhis dust collector is adapted to be used in connection with a rotary polishing or bung wheel afand comprises a substantially rectangular sheet metal housing` or dust-receiving case -1 having an inlet opening 2- in its front side and an outlet -3- in one end, the outlet being surrounded v by a laterally projecting tubular fan case -4- in which is located a rotary fan or blower -4-.

tube -5 yis fitted at one end upon the outer end of the fan case -3- and extends vdownwardly therefrom the lower end being disposed vertically and open at the bottom to allow 'the escape of the circulating air.
Within the upright lower end of the conduit 5ais located a plurality of, in this instance two, partitions or battle plates -6- and 7 inclining upwardly and inwardly from opposite sides of the conduit to form vdust-collectingpockets -6- and -7-.
The partition -6- extends upwardly from a plane below and some distance above that of the upper end lof the partition 7- and in spaced relation thereto so as to adoid a free passage for the escapingair between the partitions which are, therefore, disposed in intersecting planes at an angle to the axis of the extension 5.
That is, the partition -6- extends from one side upwardly and inwardly in an inclined plane andterminates at its upper end some distance from the opposite side of said extension beyond the vertical plane of the 'upper edge of the partitionl -7- which terminates some distance from the partition 6- to f orm the intervening air-passage previously mentioned.
The object in arranging the partitions in the manner described is to cause the heavier particles of dust, such as gold, silver and other more or lessvaluable dust, to bel collected in the pockets -7- and -6- while at the same time permitting the escape ofthe circulating air.
lThe front inlet side of the housing -l is preferably funnel-shape to facilitate the entrance of the dust-laden air which is drawn into the housing by the rotation of the fan or blower -etfd at substantially right angles to the axis of the exit opening -3- thus producing more or less eddying currents in the rear of the housing to allowthe precipitation of the heavier particles of vdust into the bottom thereof where it is collected within .a removably tray -8.
rllhis tray is slidable along and upon the iio of some distance above the bottom of the tray so as to overhang the adjacent portion of said bottom, thus producing an intervening dead air chamber to facilitate the collection of the heavier particles of dust before passing out through the outlet -3-.
The polishing or bufiing wheel -a- 1s preferably located in the mouth of the inlet -2- of the housing -ljust above the bottom of the tray -8- so that the heavier p articles of dust, resulting from the polishing or buiing operation, are precipitated directly upon the tray, while the lighter particles are carried w1th the current of air through the outlet and are collected in the pockets -G- and -7- and it, therefore, follows that the air which escapes from the discharge end of the conduit -5- is praetieally free from dust.
The polishing wheel -a' is shown as secured to an armature shaft bof an electric motor -B- which, together with the housing -1-, are mounted upon a suitable supporting bed or table -C- so that the axis of the shaft -b-- and wheel -ais substantially parallel with that of the outlet -3-, or at right angles to the inlet openino z'The fan or blower -1- is secured to a suitable shaft -10- which is coaxial with and extends through the outlet -3- and is journaled in bearings -11- on the outer end of the housing -1- and inner end of the blower ease JI- The outer end of the shaft -10- is provided with a pulley -12-- which is connected by a belt -13- to a pulley 1lon the armature shaft -1)- so that the buffer wheel and fan may be driven by the same source of ower as the motor I3- It is evident, however, that the fan may be driven from any available source of power if desired.
During the polishing or bufling operation, the heavier particles of dust thrown off by the wheel -aare precipitated directly into the tray -8, -the flange -9- serving to hold back the particles which may lodge on the bottom of the tray against moving air currents produced by the fan -4--, While at the same time the suction produced by the fan may remove the lighter particles of dust from the tray and cause theln to be carried with the moving current of air into the eX- tension -5- where the partitions -6- and -T- wrve to trap any of the heavier or more valuable dust into the pockets 6- and -7-, while lthe air which is free from the dust is allowed to escape through the passage formed between the partitions.
When it is desired to recover this collected dust, the tray -8- may be removed in the manner previously described, and its contents emptied into a suitable receptacle.
In like manner, the extension -5 which is telescopically fitted upon the outer end of the fan ease lmay also be removed and inverted to deposit the contents of the pockets and -7- into the saine receptacle from which the more valuable dust may be separated from the valucless particles by any suitable method of separation, not necessary to herein illustrate or describe.
It is now apparent from the foregoing description that the purpose 0f the device is two-fold.
First,-to remove the dust produced by the polishing wheel from the atmosphere, and thereby avoid its inhalation by the operation, and
Sccond,-,to recover the valuable particles, such as gold and silver,-which may be removed from the -article operated upon.
What I claim is:
.1. The combination with a rotary abrasive element, a dust-receiving case having an open side adjacent the abrasive element, a tubular fan case communicating with the dust-receiving case, a rotary fan in the fan ease, an upright dust-collecting tube connected to the delivery end 0f the fan ease and provided with interior pockets opening toward the fan case, and a tray slidable into and out of the dust-receiving ease and provided with an overhanging inturned flange at the side adjacent the fan case.
2. The combination with a rotary abrasive element, a dust-receiving case having an open side adjacent the abrasive element, a fan case connected to the receiving case above the bottom thereof, a rotary fan in the fan case, and a dust-collecting tube having one end connected to the delivery end of the fan case and its other end extended downwardly and provided with partitions inclining inwardly and upwardly from thc walls thereof to form interior pockets opening toward said delivery end of the fau case for collecting the dust and retaining it when the fan is at rest.
In witness whereof I have hereunto set. my hand this 13 day of October, 1916.
FRED ROESE.
