SPECIFICATIDN forming part of Letters Patent No. 628,187', dated July 4, 1899. Application filed January 24, 1899. Serial No. 703,241. (No model.)

To all whom, it may concern:

` Be it known that I, JosIAH S1BLEY,a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Suction or Injector Conveyers, which improvement is fully set forth in .bers being provided with lianges and bolts connecting the same, one of said flanges having a shoulder on which the eduction member is supported and may be moved, so as to adjust the aforesaid passage, as will be hereinafter fully described, and pointed out in the claim that follows the specification.

Figure l represents a central longitudinal section of a suction or injector conveyer constructed in accordance with this invention. Figs. 2 and 3 represent transverse sections taken, respectively, on lines x and vy g/ of Fig. l. Fig. 4. represents a perspective view, on a reduced scale, of the member having the induction-passage.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A and `B designate, respectively, the induction andl eduction members having the alining passages A and B', the forwardend of the member A entering the rear end portion of the member B and serving as a nozzle. On said member A, rearward of the nozzle, is the flange F', on the inner side of which is the annular shoulder H, the latter projecting forwardly from said flange and surrounding the nozzle portion of the member A.

Between the shoulder H and the end of the nozzle is a grooved wall G, forming one side of an annular chamber D, hereinafter referred to, and the end of the nozzle terminates in a tapered portion made by exteriorly chamfering the end portion thereof, as at J, which is separated from the opposite wall P of the member B, forming the passage C.

. The innerend portion of the eduction member B is provided with a bell or outward flare, and at the rear end thereof .has an annular iiange K, the side face L of which coincides with the face F of the flange F', said lianges F' and K being fastened together by the bolts M. The inner flared end of the member B encircles the shoulder H and rests` thereon, serving to support the said member B, assisted bysaid bolts M,the shoulder K relieving to a considerable extent the bolts of the weight of the members one on the other and tightly closing the rear of the chamberD. Theshoulder H also supports the packing that may be interposed between the faces of the fianges, it being evident that Vthe member B may move in and out on the shoulder H in the adjustment of the size of the passage C. The interior wall N of the bell end or flared portion of the member B forms a groove and is opposite the wall G of member A when `the parts are assembled, the two grooved walls forming between them the said annular chamber D herei-nbefore referred to. The chamber D communicates with a suitable source supplying air, steam, or the like under pressure through a nipple E in the bell portion of member B. A Y

The curvature of the swell P and the chamfered end J coinciding, the passage C has parallel walls, and the pitch of said walls gives said passage an inclination, so that the current issuing therefrom' is discharged at an angle to the walls of the eduction member, as shown by the arrows in Fig. l. p

The adjustment of the size of the passage O is' attained by the insertion of packing- ,rings between the flanges when it is to be increased or by planing or otherwise reducing the thickness of the flanges F and K to decrease the size of said passage.

The operation of said conveyer will be readily understood. 'lhe member A communicates with the source from which the liquids or solids are to be conveyed, and the member B communicates with the delivery. The annular jet entering the member B, as shown by the arrows in Fig. l, induces a current and thegmovement of the material in an obvious manner. The durability and simplicity of this structure are important features of the in- IOO vention, it being noted that the two members or pieces constituting the device are strong castings and that they are coupled in a manner that affords an ample support, the bolts and interfelting bell and annular shoulder of the members assisting one another in maintaining the joint. The formation of the annular chamber D by opposing grooved Walls in the overlapping portions of the members is another advantage gained in the construction of a device of this character, as it aords a simple and effective structure. The passage C is formed in a novelvand advantageous manner, and the adjustment of its size is attained by an extremely simple provisionthat is to say, said passage C being formed by correlatively-curved and approximately parallel walls of the members the relative longitudinal movement of the same increases or reduces the size thereof, and the interposition of packing rings or Washers or the reduction of the flanges obviates the employment of screw-threads or the like.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

An injector conveyer consisting of an induction member having a nozzle at its for- Ward portion, an eduction member havingits rear portion freely receiving said nozzle, with a passage adjustable in width between said members, a chamber on the eduction member around said nozzle, an inlet to said chamber, flanges respectively on the periphery of each member and bolts connecting the same, and a shoulder on the side of the iiange of the induction member on which the rear.portion of the ed uction member is adjustably supported.
