SAND-BLAST APPARATUS FOR CLEANING MOLDS.
SPECIFICATION forming part of Letters Patent No. 554,300, dated February 1 1 1896. Application filed April 30| 1895. Serial No. 547,619. (No model.)
To all whom t may concern:
Be it known that I, JOHN E. PARKER, a citizen of the United States, rcsidingat Chicago, in the county of Cook and State of Illinois,
5 have invented a certain new and useful Improvement in Sand Blast Apparatus for Cleaning Molds, of which the following is a speciiication.
y My invention relates to sand-blast apparaio tus particularly adapted for iinelyground and bolted sand and designed for service as a means for cleaning molds.
The object of my invention is to provide a simple construction and to cause the sand to rise in the form of a cloud preparatory toits discharge along with the issuing blast of air, thereby avoiding clogging and caking of the sand, which should be directed against the mold in a finely-powdered condition, so as to 2o avoid cut-ting and unduly wearin g the surface of the mold.
In the accompanying drawings, Figure l represents an apparatus embodying my invention, the drum or casing being shown in.
vertical central section and the remaining portion of the apparatus being shown in elevation. Fig. 2 is a sectional plan on line vos in Fig. l. Fig. 3 is a bottom plan of the annular air-blast distributer.
3o A indicates a closed drum in which the sand is to be contained. The closed chamber a within this drum is to be only partially filled with sand, and as a means for introducing a suitable supply the drum can be provided 3 5 with a removable cap a. The air-blast pipe B is connected with any suitable means for supplying a blast of air, and is arranged to enter the closed chamber through the lower portion of the drum. This pipe B terminates 4o in an annular pipe portion b2, which is arranged within the lower portion of the cham ber. This annular pipe portion b2 is perforated, so as to permit the air-blast to issue in jets, and thereby be diffused in the body oi sand. Said pipe portion b2 constitutes therefore a distributer for the air-blast.
The outlet-pipe C, which may be termed the sand-blast pipe, extends upwardly and centrally through the bottom of the drum and has a T-shaped receiving end c arranged within the upper portion of the chamber. D
indicates a flexible pipe or hose which is connected with the lower end of the sand-blast pipe C and provided with a suitable nozzle d.
E indicates a pipe whichl is provided with a cock or valve e and arranged to form a bypass between the air-blastsupply pipe B and the sand-blast pipe C, it being observed that the pipe B is provided with cocks or valves b b, and that pipe E connects with pipe B at 6o a point between said valves, and also oonveniently connects with the lower portion of pipe C.
The air-blast admitted into the body of sand within the chamber a causes the sand to rise in the form of a cloud, and hence the sand thus carried up is carried by the outgoing air into the ends of the T-shaped receiving end of pipe C, and thence down such pipe and to and through the flexible pipe D and its noz- 7o zle. The volume of sand in the discharging sand-blast can be varied by adjusting the cock or valve e. Thus if it is desired to lessen the volume of sand, the cock e can be opened so as to admit a portion of the air-blast from pipe B directly into the pipe C, and in this connection further regulation can also be made by adjusting the cock or valve b. In order to entirely cut off the blast, the cock or valve t can be closed. I 8o That I claim as my invention isl. A sand blast apparatus comprising a closed chamber in which the sand is contained, the sand-blast pipe having its receiving end arranged within the upper portion of the chamber and the air-blast-supply pipe connected with means for supplying the blast and terminating in a perforated blast-`distributer arranged within the lower portion of the chamber and constructed and positioned 9o to direct the blast-air in jets into the body of sand so as to cause the same to rise in the form of a cloud of dust, substantially as described. y
2. A sand -blast apparatus comprising a closed chamber in which the sand is contained, the sand-blast pipe AC extending np through the bottom of the chamberA and having its receiving end arranged within the upper portion of the same, and theair-blast-sup roo ply pipe B terminating in an annular periorated distributer which is arranged within the lower portion of the Chamber, substantially as described.
3. A sand-blast apparatus comprising the drum A, the smid-blast pipe C leading from :L point Within the upperportion of the drum, the valved adr-blast-supply pipe B connected with a suitable source of supply and terminating in a perforated distributor which is arranged within the lower portion of the drum, l and a Valved luy-pass E connecting the pipe 1o B with Jhe pipe C, substantially as described.
