Application September 20, 1937, Serial No. 164,790 2 Claims. (Cl. 103-267) This invention relates to steam jets for lifts Clamped between the body 3 and the ?tting 6'is especially adapted for conveying particles of solid an inverted cone-shaped member ll having an matter in water to a desired height and has for ori?ce l2 in the apex portion thereof. The the primary object the provision of a device of diameter of the ori?ce is substantially equal to this character which will reduce to a minimum the chances of clogging by particles of solid mat ter and will utilize a smaller amount of steam for the successful elevation of materials to a maxi mum height than required by jets now in use. 10 With these and other objects in View, this in vention consists in certain novel features of con struction, combination and arrangement of parts to be hereinafter more fully described and claimed. ll For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a vertical sectional view illustrating a steam jet constructed in accordance with my invention. Figure 2 is a sectional view taken on the line 2-2 of Figure 1. Referring in detail to the drawing, the numerals l and 2 indicate conveyor tubes, the tube 2 being located at right angles and in a plane above the tube l. The tube 1 acts to receive liquid and particles of solid matter and the tube 2 acts to discharge said liquid and particles of solid matter to a desired height. In order to cause the liquids and particles of solid matter to pass from the tube l and through the tube 2 my inven tion is employed which consists of a steam jet so constructed that a minimum amount of steam will develop sumcient lifting action to successfully as sure the discharge of the matter and liquid at a maximum height. The steam jet consists of a housing 3 having detachably secured thereto by bolts 4 ?ttings 5 and 6. The ?tting 5 threads onto the tube 2 while the ?tting 6 bolts onto the tube l and in cludes angularly related portions A and B. The portion B aligns with the tube I,v while the por tion A aligns with the tube 2. A sleeve 1 forming an ori?ce of a selected diameter is mounted. in the housing 3 with its uppermost end terminating within the tube 2 and the lower end has formed thereon an en largement 8 of adiameter slightly smaller than the internal diameter of the housing 3 and is equipped with an adjustable packing gland 9 to establish a leak-proof connection between the housing 3 and the sleeve 1. A spider I0 is detach ably secured on the housingv and is adjustably connected to the sleeve 1 whereby said sleeve may be raised and lowered in the housing. the internal diameter of the sleeve 1;. The cone shaped member II cooperates with the enlarge ment 8 of the sleeve 1 of the housing 3 in forming a steam chamber l 2’ fed by steam from a supply, pipe I3. The lower end of, the sleeve 1 is beveled and spaced from the cone-shaped member II a 10 selected distance to form an annular steam ori ?ce M which places the steam chamber l2’ in communication with the interior of the sleeve 1. The steam from the chamber l2’ escapes into the sleeve 1 in substantially conical formation 15 exerting the greatest pressure next to the walls of the sleeve 1 and less pressure within the space centrally of the walls of the sleeve 1. A steam nozzle I5 is carried by the ?tting 6 and has its discharge end terminating in the conical shaped member H and is arranged in axial alignment with the passage de?ned by the sleeve 1 and the ori?ce [2 of the conical shaped member ll so that a stream of steam will be discharged centrally’ through the sleeve 1 which with the conical 25 shaped ?ow of steam by the ori?ce M will produce a maximum amount of suction in the ?tting 6 and tube l for conveying the liquid and solid mat ter upwardly through the sleeve 1 into the tube I where the pressure of the steam carries said 30 liquid and solid matter entirely through the tube 2 to a selected height without danger of the solid matter clogging the sleeve 1 or ori?ce l2 of the conical shaped member I l. ‘Steam introduced into the sleeve 1 by the ori?ce l4 and the nozzle 35 l5 requires a less amount of steam for the lifting of the'liquid and solid matter than ?ttings now in use with the chances of clogging reduced to a minimum. The ori?ce l4 may be increased and decreased 40 in size by adjusting the sleeve ‘I relative to the conical shaped member II. The nozzle I5 is de tachable from the ?tting and different size noz zles may be employed to meet variable working conditions. It is preferable that the discharge 45 end of the nozzle I5 terminate a distance‘ from the ori?ce [4 which will equal the internal diameter of the sleeve 1. What is claimed is: 1. A steam jet for lifts comprising a housing 50 adapted to be connected into a conveyor tube and having an annular steam chamber connected to a steam supply, a sleeve having a uniform internal diameter extending downwardly in said housing and closing the upper portion of the housing, said 2 2,136,304 sleeve being located centrally of the steamy cham ber, an inverted substantially conical-shaped member mounted in said housing and extending into the steam chamber from the lower end of the housing and having an ori?ce in alignment with the sleeve and spaced from the lower end of said sleeve to provide a conical-shaped passage between the steam chamber and the sleeve where by steam discharging from the steam chamber 10 into said sleeve will be in a conical-shaped flow for producing greater pressure adjacent the walls of said sleeve than axially thereof, and a steam nozzle for discharging steam axially through said conical-shaped member and axially through said 15 sleeve with its discharge end located below the ori?ce of the inverted substantially conical shaped member. 2. A steam jet for lifts comprising a housing adapted to be connected into a conveyor tube and 20 having an annular steam chamber connected to a steam supply, a sleeve having a uniform internal diameter extending downwardly in said housing and closing the upper portion of the housing, said sleeve being located centrally of the steam cham ber, an inverted substantially conical-shaped member mounted in said housing and extending into the steam chamber from the lower end of the housing and having an ori?ce in alignment with the sleeve and spaced from the lower end of said sleeve to provide a conical-shaped passage between the steam chamber and the sleeve whereby steam discharging from the steam chamber into said sleeve will be in a conical-shaped flow for pro ducing greater pressure adjacent the Walls of said 10 sleeve than axially thereof, a steam nozzle for dis charging steam axially through said conicalshaped member and axially through said sleeve with its discharge end located below the ori?ce of the inverted substantially conical-shaped mem ber, a spider mounted in the housing and having the sleeve extending therethrough, and means for adjustably connecting the sleeve on the spider whereby the sleeve may be adjusted relative to the inverted substantially conical-shaped member to increase and decrease the size of the steam pas sage between the sleeve and the steam chamber.
