1 Claim.

This invention appertains to new and useful improvements in cleaning devices and more par: ticularly to a novel tool for cleaning out bored or tapped openings.

The principal object of this invention is to provide a pneumatic tool for cleaning out and removing foreign matter from openings of various kinds, such as drilled and tapped openings in either metal or wood, as well as in stone work.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a vertical longitudinal sectional view through the tool.

Fig. 2 represents a bottom plan view of the tool.

Fig. 3 represents a vertical transverse section of the tool taken substantially on line 33 of Fig. 1.

Fig. 4 represents a perspective view of the outlet shed.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the casting includes a material collecting receptacle 5, and a depending barrel 6 adjacent thereto and connected to the receptacle 5 by the neck portion 7. The lower end of the barrel 6 is slightly reduced and projecting downwardly below this end of the barrel 6 and extending longitudinally through the barrel is the air plant tube 8 which has its discharge end 9 reduced to, afford a fine forceful discharge of air. The upper end of this tube 8 terminates in the bore 9 which is partly threaded to receive the threaded nipple 10 on the elbow 11 to which the air supply line 12 communicates and between which and the air supply line, the air control valve 13 is mounted.

The upper portion of the barrel 6 is provided with a baffle plate 16 which in the form of a shed projects into the upper portion of the receptacle 5.

Vertically disposed bafile plates 17,18 and 19 are arranged between the side walls of the receptacle 5, immediately beneath the baffle plate 16,20 representing an additional baflle plate which projects inwardly from the back wall of the receptacle 5.

The baflles l7, l8 and 19 are arranged in parallel relation, but in horizontally offset relation. Nu-

meral 21 represents a cup-shaped closure which is connected to the bottom of the receptacle 5 by e the hinge 22 of the spring type and this closure 21 fits into the opening 23 in the bottom of the receptacle.

In Fig. 4, numeral 24 generally refers to the outlet shed for the air and this shed consists of a 5 rectangular plate 25 having downwardly and inwardly extending back portions 2626. One end of the plate 25 is provided with a downwardly and inwardly extending end wall 27. Screws 28 pass through openings 29 in the plate 25 for securing this shed 24 to the top of the receptacle 5 mainly over the outlet opening 30 and interposed between the top of the receptacle 5 and the inwardly turned portions of the side and end walls is the mesh screen or filter 31.

It can now be seen that the barrel 6 can be arranged over a drilled or tapped opening with the lower end of the tube 8 depending therein. By opening the valve 13, a blast of air will be discharged from the end 9 of the tube 8 and this air will force all of the foreign matter in the opening upwardly through the barrel 6 and into the receptacle 5. All material will strike the bafiles 17 to 20 inclusive, and will gravitate to the bottom of the receptacle 5,while the air will pass upwardly around the bafile plate 16 and out through the shed 24, being screened to pass it through the sheet 31, so that no dust will permeate the air exteriorly of the tool.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described our invention, what we claim as new is:

A dust separator comprising a shell having an inlet, a horizontal shed-like structure projecting inwardly of the shell from adjacent the said inlet, said shell being provided with an air outlet, said shell being provided with a dust depository at its lower portion, said shed-like structure being interposed between the depository and the air outlet and adapted to direct an inflow of air across the shell above the dust depository, said shed-like structure terminating in close spaced relation with respect to the wall of the shell opposite the said inlet, and a plurality of baflie members positioned below the said shed-like structure in horizontally spaced and vertically offset relation to cause the flow of air under the shedlike structure to follow a tortuous route.
