UNITED STATES PATENT OFFICE.
GUSTAVEA. LEIMAN, on NEW YORK, N. Y.,
ASSIGNOR TO LEIMAN macs, on NEW 7 YORK, N. Y., A COPARTNERSHIP COMPOSED OF WILLIAM H. 'LEIMAN, GEORGE W. v
LEIMAN, GUSTAVE A. LEIMAN, EDWARD C. LEIMAN, AND JOHN LEIMAN.
DUST COLLECTOR FOR POLISHING MACHINES.
To all whom it may concern:
Be it known that I, GUs'rAvE A. LEIMAN, a citizen of the United States, and resident of the borough of the Bronx, in the city and State of New York, have invented a new and useful improvement in Dust Collectors for Polishing Machines, of which the following is a specification.
This invention relates to an improvement in dust collectors for polishing machines, and has for its object to provide a novel means for collecting the dust drawn into the machine.
Another object is to provide a machine including a partial vacuum dust collectingchamber havingpartitions angularly inclined and arranged to form upper compartments having restricted outlets, a compartment intermediate the upper compartments, and a lower compartment, said intermediate compartment having a strainer for the dust laden air removably secured therein. 7 Another object is to provide a machine including a partial vacuum dust collecting chamber, passages connecting the hoods with the vacuum chamber, and an exhaust opening at the top of the chamber between the passages.
Another object is to provide novel means 3 in the mounting of the motor between the exhaust fan and the spindles for driving both the fan and spindles.
Another object is to provide certain improvements in the form, construction and s5 arrangement" of the several parts, whereby the aoove named and other objects may be effectively attained.
is represented in the accompanying drawin s, in which+ ig. 1 represents a plan view of the machine.
Fig. 2 represents a front elevation of the same, one of the doors of the dustcollecting 46 chamber being shown in its open position, and other portions being broken away to show parts within.
Fig. 3 represents an end elevation of the machine, and Fig. 4 represents a vertical centralsection taken in the plane of the line IV-IV of Fig. 1, looking in the direction of the arrows. V The polishing head is denoted by 1,.and
- journaled in thehead 1 and A practical embodiment of my invention is shown as provided with two op ositely disposed spindles 2, 3, arranged at t eends of a horizontal shaft 4. This shaft 4 is receives its motron from a notor 5 having a vertically disposed shaft 6 upon which is secured a bevel gear T'arranged to mesh with a bevel gear 8 fast on the spindle shaft 4.
The motor 5 issuspended from a plate 9 which is fixed to the polishing head and secured to the table top 10 by means of screws 11, which table topis supported on legs 12. An exhaust fan 13 is mounted on the lower end of the motor shaft 6.
and a-compartment 23- interposed between the upper compartments '20, 21. The compartments 20, 21 and 23 are formed by partitions 24, 25, angularly inclined, which partitions extend downwardly from the top of the chamber'and form restricted outlets 26, 27 for directing the passage of the dust laden air into the compartment 22. The compartments 20 and 21 are in direct communication with the hoods through the pipes18, 19, re-' spectively. The lower end of the partitions 24, 25, are provided with oppositely disposed channels 28, 29, which serve as guide rails and support for a frame 30 upon which is fixed an inverted wire basket 31 of fine mesh. A flexible strainer 32 of muslin, or other similar material, is removably secured within the frame 30. The" basket 31 and strainer 32 are arranged to extend upwardly into'the intermediate compartment 23. The lower compartment 22 is provided with a tray 33 in which may be placed a liquid to arrest certain of the matter entering the compartment 22.
To remove the frame and basket from their positions in the compartment 23, the chamber has an opening 34 which is closed by doors 35, 36,'hinged to the legs 12 at 37,-
3 8, which doors'are locked in a closed'position by means of fastening devices 39, 40,
arrangedto coact with stops 41, 42, carried by the chamber. The peripheral walls of the opening. 34 are provided with a binding of felt, or other similar material 43, Wl 1f(=l1 coaets with the doors, a substantially air tight closure. Air is exhausted Ircm the chamber with its severalcompartments through an opening 44 in the top of the compartment 23 immediately beneath the exhaust fan 13, The
chamber is positioned within the legs 12 by rivets, or suitable fastening means 45, a distance below the table top to form a cabinet therebetween, which cabinet is constructed by a front wall 46 and side walls 47, 48,1eavingan outlet 49 at the rear. These front and side walls enclose and conceal the ex-' haust fan 13 and pipes 18, 19, and cause the air withdrawn from the chamber through the opening 44 to be exhausted at the back of the machine and away from the operator. in operation: By' reason of the rotation of the fan 13, air will be Withdrawn from the dust collecting chamber through the opening 44, thereby causing a partial vacuum in the several compartments, which vacuum will be relieved by drawing or sucking air and dust downwardly from the hoods 1 ,14, 15, through pipes 18, 19, into compartair, passes ments 20, 21, through restricted openings 26, 27,. thence into the lower compartment 22 and upwardly into the compartment 23. The air will, of course, pass throu h the strainer 32 and basket 31 upwardly through the opening 44 into the cabinet and be exhausted through the outlet 49 at the rear, while the dust will be arrested by the strainer 32 and finally fall by gravity into the liquid in the tray 23. As the dust laden through the restricted openings 26, 27 into the compartment 32, a portion" from its position in the compartment 23:
- tially parallel with the wa rangement-of the several flexible, the suction of the f the dust may be caused by gravity to fall in the liquid in the tray. To clean the basket and strainer, the frame may be withdrawn the strainer, o'r'the changing'of the contour,
assists in relieving-the strainerof cumulation of'dust and dirt. .It isevident that variouschanges me be resorted to in thelio'rm, construction an arwithout' dea'ny acparting from the spirit. an
when closed, topresent comprising,
scope of my inmam "vention; h'ence,-'-I'do not intend to be limited tothe specific details herein shown and described, except as the claims.
What I claim is:
1. A dust collector for. polishing machines comprising, a plurality of inlet compartments, an outlet compartment interposed between said inlet compartments, a settling compartment common to the inlet and outlet compartments, a screen removably secured in the outlet compartment, and a fan located in close proximity to the outlet compartment for exhausting the air from the compart ments.
they may be included in' 2. A dust collector for polishing machines 4 comprising, a plurality of inlet compartments having restricted elongated outlets,
an outlet compartment interposed between said inlet compartments, a settling compartment common to the inlet and outlet compartments, a: screen reniovablysccured in the outlet compartments and a fan located in close proximity to the outleticompartmcnt for exhausting the air from the compartments.
3. A dust collectorv for polishing machines comprising, a plurality of inlet compartments, an outlet compartment interposed between saidinlet compartments, certain of the walls of each of said inlet and outlet compartments being inclined toward its outlet, a settling compartment common to the inlet and outlet com artments, a screen removabl I secured in t '0 outlet compartment, and a an located in close roximity to the outlet compartment for ex austing the air from the compartments 4. A dust collector forpolishing machines a chamber having angularly incli'l'ied partitions arranged to form a plurality of inlet compartments, an outlet compartment and a settling compartment, a screen removably secured-in the outlet compartment, and a fan located above said chamber in close proximity to the outlet compartment for exhausting the air from the compartments.
5.; A dust collector for polishing machines comprising, a chamber having angular-1y inclined partitions arranged to form a plurality of inlet compartments, an outlet comartment and a settling compartment, said inlet and outlet compartments having restrictedoutlets, a screen removably secured in the-outlet compaitment, and a fan located above said chamber in close proximity to the 1 V eus'mvn A.
