CONVEYER-ELBbW.
Specification of Letters Patent.
Application filed March 29, 1911.
Patented Nov.
Serial No. 617,609.
veyers, either by forcing a draft of air through a conveying duct or by inducing an air current by exhausting from an inclosed tank into which the conveyed material is received, a considerable amount of abrasion has been found to occur at elbows or turns in the conveyer duct.
The object otmy invention is to provide means for minimizing such abrasion and reduce the frequency of renewal of the abraded parts.
In the accom muying sheet of drawings which forms a part of this application" Figure tie a longitudinal section through an inclosed elbow embodying my invention on the line I-I of Fig. 2. Fig. is a cross section on the line I--ll ot Fin. t.
The invention is illustrated in .'Ullllt('tl0[1 with a flang d elbow east with a pocket P at its bend. The mouth of the pocket is substantially (lUSttl or bridged by a wear plate W for which manganese steel is a suitable material.

Its inward movement is limited by bolts B B, which project through the rear wall of'the pocket. Nuts N N on the bolts and'accessible. outside the elbow secure the wear plates and serve .as a means for its adjustment. The inside of the bend of the elbow is provided with an opening which is closed by a plug 0. Through this opening the wear plate can be inspected and removed and renewed when necessary. \Vhen there is a partial vacuum inside the elbow, the air back of, or behind the wear plate forces itinward, and tends to hold it in place against the impact of the material conveyed.
