This invention relates to a dust collector, the general object of the invention being to provide a light, simple and compact device for collecting dust from grinding, sanding, polishing and similar machines, as well as dust and shavings from saw or planer machines and any other machine or device from which foreign matter should be caught and not permitted to mingle with the air in a room in which the device is placed,
The present machine is more especially designed as a dust collector for a grinder device used for smoothing the edges of photographic prints, and may be used for any n grinder or similar device where the objects are handled with great rapidity, though it will, of course, be understood that the device is capable of use in any situation wheredust or light and dry refuse matter is to be separated from air.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims. i
In describing the invention-in detaihreference will be had to the accompanying 30 drawings wherein like characters denote like or corresponding parts throughout the several views. and in which I Figure 1 is a front view of the device.
Figure 2 is a section on line 22 of Fig ure 1.

In these drawings, the numeral 1 indicates a hopperregistering with a hole in the part 2, said hole being connected with guy-the outlet of the grinder. A screen 3 forms a partitionin the hopper and acts to catch and hold any prints which may be drawn into the hopper by excessive pressure on the grinding troll. Doors 4 provide access to the space above the screen so that the prints can be removed. A pipe 5 connects the lower end of the hopper with the rear of a casing 6 and the inlet of'a fan? is connected by a pipe'8 with the side of, the casing, the connection of the pipe 5 with the casing being nearer that side of the casing to which the fan is connected than the other side, as shown in Figure 1. I An L-shaped partition 9 is located'in the casingand extends from the front to the rear thereof,zwith its top part spaced from the top of thecasing and its vertical part spaced from that side of the casing which is in com'munica,
tion with the fan sothat'said partition forms an L-shaped passage 10 at the top and one side of the casing; I The free edge of the horizontalapartof the partition terminates shortof the adjacent side of the casing so as to' leave anaopening which places the passage in communication with the rest of the casing. This free edge of the partition is formed with 'a depending part 11. The pipe 5 is in communication with the casingand enters the casing adjacent the vertical part of the partition. r Y 1 V j A diagonally arranged baflie 12 depends from the horizontal part of the partition an appreciable distance from the depending part 11 thereof and a pair of diagonally arrangedbafiles 13 extend upwardly from the bottom; ofthe casing, these baffles 13 being located one on each side of the baffle 12 so that the three' baffles form a zigzag passage ex- 7 ably arranged in the bottom of the casing and occupying the space between the vertical part of the partition 9 and the left side of the easing and said drawer has its front extended upwardly, as at 16, to act as a cover for the front of the Easing, which is open for the greater part of its area.
The chamber 14 acts as an expansion chamber for the dust laden air entering the same from the pipe 5 so that the velocity of the air is reduced and its direction is altered by the first baffle 13 and the bafiies cause the air to take a zigzag path before it enters the L- shaped passage 10. Thus this reduction in the velocity of the dust laden air and the change in direction as induced by the 'bafll'es, clears the air of dust and other foreign matter and this matter will drop into the drawer so that it can be removed whenever desired. The clear air will flow through the passage 10 into the pipe 8 and then into the fan. By having a lar e opening in :front of the casing covered by t e front 16 of the drawer, the bafiies 13 I are removed with the drawer so that the dust collecting between the bafiies 13 as well as that collecting in other parts of the drawer can be readily removed by pulling the drawer from the casing and emptying the same. The arrows in Figure 3 show the course of the air as it is drawn through the device by the suction created by the fan.
Figure 5 shows a modification in which a hopper 17 forms the bottom of the casingand takes the place of the drawer. The. bafile plates 13 are attached to the walls of the easing as shown. Thus the hopper 17 receives the dust.
It is thought from the foregoing description that the advantages and novel features p of the invention will be readily apparent.
It is to be understood thatchanges may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
What I claim is V 1. A device of the class described comprising a casing, partitions dividing the casing into a chamber and an .L- shaped passage, the
:horizontal limb of the passage being in communication with the top of the chamber, means for introducing the air to be cleaned into the chamber, a suction device connected with the Vertical limb of the passage, a short baffle depending from the free edge of the top partition, 21 long bafile depending from said partition, a drawer fitting in the cham-' casinga suction device connected with the
