This invention relates to sanding machines and more particularly to means forremoving to draw all the substances-that may have accumulated on the sanderduring the opera- Y ally floating about the .room accumulating not only onthe machine `and in the `room but also on the operator. Obviously when a machine of this type is in operation throughout the day, an operator has to work under very unhealthy conditions. i
According to my inventlonIhave succeeded in constructing a sandingV machine wherein allv particles of dust or other sub1-YYY stances on the sander are removed, resulting in healthful conditions inthe room in which the machine is located. Also in addition to removing the dust particles from the sander, the life of the sander is materially lengthened due to the fact that the sander is prevented from becoming glazed or clogged with the dust accumulated thereon.
An object of my invention is to provide a new and improved type of sandingmachine wherein all substances accumulated on the v sander are removed during the operation of the machine.
' Another object of the invention lis to materially lengthen the life of the sander by preventing it from becoming vglazed or clogged. Y Y
These and other objects of my invention will be hereinafter pointed out in the accompanying specification and claims and shown in the drawing which shows by Way of illustration what I claim to be a preferred embodiment of my invention.
In the accompanying drawing I have shown for the purpose of illustration one form of mechanism embodying the invention in which a front elevational view of my sanding device is shown.
1927.11` semi No. analisti.'
i. The: preferredgform of i my invention consists off'a sander beltfm'ountedzonsuitable roll-`v ers rotatedbygmeans fof a motor. During fthe j operation of the machine, the belt in passing f l a predetermined point will be'ac'ted uponby ablast offair whichwill loosen'all dust par` ticl'eswhich vmay have accumu'latedonsthe belt al suction e device in turn removing the` loosened .particles from the machine.
i-Referencewill now be had to the drawing l wherein theconstruction of my device is illusf traited. r4Thesanderxbelt 10 is mounted upon a plurality of rollers 11 and l1,the roller 11.:
being rotatablymunted onfan arm 12.-1 The arm'12as will be noted is'pivot'edat 13'a11d carries at its opposite end a'weight 14 which at Valltinnes keeps 1a yielding tension on .the
sander "beltj 10 so that an operator may easilyl l pr'ess the sander :belt vagainst fthe board l5 during the-operation of .thevmachine 2A mo-V ltor (not shown)"ofsuit'able power islconf nectedjto theshaft 16 uponwhich one ofthe Y rollers 1l is; rigidly mounted. main pipe 1'( @havingajlaterally-extending pipe 18 con-- y i n eCted `.thereto byV an elbow. 19 projects -beneath the sander belt .as viewed inthe figure.
Connected at 20 to the vmainpipe 17 through s1 1i table elbows;v is another laterally extend# ing `pipe 21; AEachlof thepipes 18 and 21 has a plurality of holes 22 thereinthrough-which compressed air; is `forced against the .sander belt/.110.` .Suitable `shieldsV `23 and 23.` 'enclose thissection of the'lbel-t, therefbeing sufficientv clearance betweenthe shields Vso thatY the belt mayypass vbetween them. The shield 23 hasA associated therewith a pipe 24 whichv is con-l nectedat its opposite e'nd to a suction `device (not'shown).- i "l fWhenlthe machine is tobe operated,a valve l20a on the mainpipe 17iis opened thereby/ah lowing compressedfair from a tankiinfsome part of the building'to escape throughV the openings 22 in thepipes 18 and 21; iA motor connected tothe shaft-16 isthen started causing tl1ehelt10 to function. It is, of course, to be/understood thatthe suction deviceconnected to the end of the pipe24eis also started. The operator witha suitable handV tool presses the .belt `10 against the-board lmoving-the" board during the sanding operation. As the belt passes the pipes 18 and 2l compressed air escaping through the holes 22 in the pipes will loosen any particles of dust which may have accumulated on the belt during the sanding operation. Preferably the holes 22 are so located that the compressed air is forced diagonallyagainst the belt toward the discharge pipe 24C. Thus all the dust loosened is sucked from the belt through the discharge pipe 24 by means of a suction device.A Obviously with aconstruction of this "kind a sanitary condition will prevail at all times.
During the operation of the machine dust that is created at the worlin'g'pointI 'tendst'o be drawn by the current of air created by the speed of the belt toward the blowing device when, aided by the operation ofthe blower, it is sucked into the shields 23 and T23 and carried from the machine through the pipe While I have shown and described and pointed out the fundamental novel features of the invention as applied to a single modification it will be understood that various omissions and substitutions'and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention. I intend tobe limited therefore only as indicated'by the scope of the following claims. y
`l. A device comprising in combination a sanding belt, a supporting pulley therefor, a casing surrounding substantially the entire periphery and side of said pulley and having openings for permittingpassa'ge of the belt therethrough, one side of said casing being provided with a suction device for conducting dust and loose particles away from the belt,
and a plurality of blowers separate from the suction device and at diametrically opposite sides of the casing and adjacent the said opening for directing air against thebelt to loosen the particles thereon 'for removal by said suction device.
2. In combination with a sanding belt and a supporting pulley therefor, a casing enclosing both sides of saidpulley and having openings for permitting passage of said 'belt through'the casing, one side of said casing being provided with a suction flue, and a blower positioned within said casing and mounted independently thereoffor blowing loose particles from thebelt surface to be removedV by said suction device.
3. In combination, asanding belt, a supporting pulley therefor, a substantially circular casing enclosing substantially the whole circumference of said pulley, said casing having a suction iue for removing particles from the belt and dust from the casing, a pair of blowers positioned within said casing and on opposite sides of said flue for blowing loose particles and dust from'the belt and casing for removal by said suction flue a single
