To 'all whom' fit may concern:

Be it known that I, Mn'rrmw A. Goonsrnno, a citizen of the United States, residing at Fremont, in the county of Dodge and State of Nebraska, have invented certain new and useful Improvements in Dust-Consumers, of which the following is a specification.

My invention relates to new and useful improvements in granite or stone dust consumers. l

The objects of my invention are to provide a practical, economical and eiiicient dust consumer, for use in connection with granite or stone neumatic surfacing machines, and which wi l obviate the inconvenience and injurious eiects on the operator attending the use of these surfacers, caused by the dust filling the air, blinding the eyes, filling the nose and covering the clothes,- and settling on everything in the room Where used. And further objects are to provide a dust consumer that is easily applied to any of the ordinary ranite or stone pneumatic surfacers, wit lout altering the same, and using the exhaust from the surfacenmechanism in the operation of the device. I accomplish these objects by the device illustrated in the accompanying drawings, in which,

Figure 1 is a side View showing the device in connection with the head of an ordi-A nary pneumatic granite or stone surfacing machine. Fig. 2 is a sectional view of the device, with a dotted line showing the surfacing point positioned ready for use. Fig. 3 is a View in detail of the reducing tubes and their relation to each other, as they ap pear on the interior of the device.

Similar letters refer to similar parts Referring specifically to the drawings, 1 is a circular funnel shaped hollow hood, with the upper or small end 2, provided with a tubular neck 3, in which is telescopically adjusted an extension pipe 4, adapted to close up around the lower portion or steel' point of the surfacer, as hereafter described. This hood 1 is provided in its side wall with an aperture 5, opening into a dust c0nsuming hollow chamber, 6, which extends `horizontally and substantially at right angles thereto. This dust consuming chamber is closed at all points except the aperture -at 5 and the bottom, where is provided with an opening 7,- extending its entire len h, and through which the refuse drops a cr transformation from dust into a congealed or solid form.

8 is a tube vertically penetrating the uper wall of hood 1, and extends downwardly into the interior thereof. The upper end of this tube is adapted to a hose, 9, connecting it with the water supply tank, at 10, which is conveniently located on and attached to the lever of the surfacer. The supplyl of water from tank 10 is regulated by an ordinary valve, at 11, inserted in hose 9.

12 is a tube extending horizontally throu h the side wall of hood 1, and forms a rig t angle or elbow 13, on the interior of the hood, with an arm 14 reaching to a point near tube 8, as it extends downwardly into the interior of 'the hood 1, the tube 8 and the arm 14 falling centrally in the opening 5 leading to the dust consuming chamber 6,

'and positioned in such manner as to cause the water passing through tube 8 to fall directly on a plane with the end of arm 14, where it is transformed into spray in the operation of the mechanism, as hereinafter described.

15 is an aperture in the hood 1, conveniently covered with screen to prevent stone chips from escaping, and is provided for the purpose of observation on the part of the operator in the conduct of his work.

Hangers, as at 16-16, are conveniently attached to the hood 1, and the dustlconsuming chamber 8, and ada ted to suspend the device by suitable hoo s to the framework of the surfacer when desired, though this is not necessary to the successful operation of the device, as it can easily be moved along with the hammer mechanism in passing over the stone.

An apron 17, is 'conveniently' attached to.'

.and adapted to o crate the hammer mechanism, and conveniently 'attached by connect- ,ing hose tothe air reservoir used in the opf' eration'of the pneumatic hammer, 19 is the exhaust or discharge from the hammer mechanism, and like 18 is rovided with the ordinary and usual cheer valves used 1n such connections.

20 is a pipe with elbows at cach end and adapted to adjustment on tube 12 and the exhaust or discharge 19 in the operation of the machinery, thus providing a conduit for the exhaust, discharging the same into the hood 1 through tube 12 and arm 14.

21 is the ordinary hammer lever, and 22 the body of the hammer mechanism, which is provided with a supporting framework, 23. The hammer is 'provided with a handle 24, and all of the ordinary attachments to the pneumatic surfacer as commonly used.

Having described the construction of my device its operation is as follows :-The steel point 4', ordinarily used in connection with granite or stone pneumatic surfacing machines, is first inserted vertically downward through the extension pipe 4, which is tele, scopically inserted in the tubular neck 2 of the small end 2 of the hood 1; the extension pipe 4 is then adjusted up over the point 4', extending to the base of the hammer mechanism. The elbow arlns of pipe 20 are then placed over the exhaust 19 and the tube 12 leading into the hood 1 the hangers 16-16 are then hooked to sta iles or eyes in the bottom of the hammer framework, and the `water tank 10 suitably secured to the lever 21, and the tube 8 is connected therewith by hose 9. Being thus adjusted as to its parts, the air from the main reservoir is turned on at 18, the inlet for the air to the hammer mechanism, and this sets the hammer in motion. The air from the exhaust 19 of the hammer mechanism passes down the pipe 20- and enters hood 1 through the tube 12. At the same time the water is forced through valve 11, permitting the same to lion' from tank 10 through hose 9 and into tube 8, and upon passing therefrom into the hood l, is suddenly and violently struck by the exhaust passing through tube 12, striking it with such force as to convert it into spray, and forcing it through the aperture 5 and into the dust consuming chamber 6. At the same time the exhaust passing out of tube 12, blows andl draws the dust made in the operation of the steel point 4', into the dust consuming chamber 6, where it meets and mingles with the spray and is thus converted into solid form, whereupon it drops out of vthe dust consuming chamber through the opening 7 therein, ready for removal.

The rapidity of the exhaust furnishes a constant supply of 'air in such quantity as to continually lill the dust consuming cham ber with the rising dust and spray when the machine is in operation, and in this way the dust is rapidly and completely transformed into av solid mass, thus obviating the scattering of the same, covering the operators and injuring their eyes, ears, nose and clothing.

Havin described my invention what I claim an desire to secure by Letters Patent tube extending horizontally through the side wall of the said hood and provided with an elbow and arm on the interior thereof; and a tube vertically penetrating the upper wall of the hood and extending downwardly therein, all substantially as set forth.

2. A dust consuming device of the character described, consisting of a funnel shaped hood, having a tubular neck and a pipe telescopically adjustable therein, and provided in its side wall with an opening leading to the dust consuming chamber; a dust consuming chamber connected to said hood and extending substantially at right angles thereto, and having an opening in the bottom extending longitudinally its entire length; a tube extending horizontally through the side wall of the said hood and a pipe adapted thereto; a tube vertically penetrating the upper wall of the hood and a hose and water tank adapted to the said tube; hangers attached to the hood and an apron secured to the large cir-cumfer-'nce thereof, all substantially as and for the purposes set forth.

3. In a dust consuming device, the combination with a pneumatic surfacing mechanism` provided with an air service pipe leading flom the reservoir to the hammerunechanism, of a funnel shaped hollow hood, having a tubular neck and a pipe telescopically adjustable therein and adapted to inclose the surfacing point of the mechanism;

a dust consuming cham er attached to thc hood having an aperturt` in the bottom; a

tube extending horizontally through the side wall of the hood and adapted to pipe connections with the exhaust of'- the hammer mechanism; a tube vertically penetrating the upper wall of the hood, adapted to hose connections with the water tank; a water tank connected with said tube and supply and cut off attachments; hangers loosely attaching the hood and dust consuming chamber to the framework of the hammer mechanism; and pipe and hose connections, all substantially as set forth.

In testimony whereof I aiiix my signature in presence of two witnesses.
