SPECIFICATION forming part of Letters Patent No. 786,991, dated April 11, 1905.
' Application filed August 4, 1904. SerialkNo. 219,437.
T .f1/ZZ whom, it may concern:
Be it known 'that I, HENRY J. PoDLEsK, a
A citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Elbows for Conveyer- Conduite, ofwhich the following is a specifiy cation sufliciently clear and exact to enable those skilled inthe art to which it appertains to make and use the'same.
The invention relates in general to conveyer-conduits. Specifically, it relates to such conduits as are used in pneumatic stackers. y
It has for itsobject to provide an elbow having reinforcing means on the inside thereof which is adapted to receive the impact of the matter being conveyed, whereby the elbow is rendered more durable.
Conveyer-conduits for pneumatic stackers, such as are applied to threshing and husking and shreddin machines, are usually formed of sheet meta and are connected at their inner ends with the blowers by means of elbows. The great mass of material conveyed by such aconduit impinges forcibly upon the outer half of the elbow, or that half having the greater radius of curvature, as it is ydei'lected thereby into the conveyer-trunk. In consequence the elbow is very soon worn through at this place, sov that it must be wholly replaced or mended in order that the stacker may still remain operative. The
resent invention overcomes this difficulty by providing a replaceable wearing-plate'on the inside of the elbow against which the material is directed. When this plate becomes worn out, it canv readily be replaced by another withbut slight expense, thereby improving the construction and operation of conduits of this class.
An embodiment of the invention is illustrated in the accompanying drawings, forminv a part hereof, in which like characters of reference designate like parts.
Figure-1 is a fragmentary side elevation of a pneumatic stacker,y artly in section, showing the application o the invention. Fig. 2
is a rear elevation of the elbows,'showing the position of the wearing-plates therein.
Referring to the drawings, Fig. 1 shows a portion of a threshing or shreddlng machine A, upon which the pneumatic stacker is mounted in the usual manner. The blowercasing B is provided with the delivery tube or mouth B upon which is mounted the elbow C. Pivotally connected with this elbow is the` conveyor-trunk D, the inner end of which is rovided with the elbow D', adapted to inc ose the upper end of and to sllde over the elbow C when the trunk is ad'usted. The two elbows are made substantia y the same radius of curvature to permit the greatest relative movement. Suitable means are provided for maintaining the elbow C in alinement with the delivery-tube and for turn ing it relative thereto and also for raising the conveyer-trunk,whereby it may be adjusted to any desired position.
All of the above-described parts may be of the usual or any desired construction.
Secured to the inner surface of the elbow C at that side having the greatest radius of curvature, where it 1s in position to v be impinged upon by the material being conveyed',
1s a wearmg-plateC, which is so proportioned f that it extends on both sides of the medial transverse plane passing throufrh the center of curvature of the elbow, an at a corre-Y s onding place in the elbow D is a wearingp ate D2. These plates, as herein shown, are made of somewhat thicker stock than the elbows and are pressed into concave-convex' wearing tendency of the material being conveyed.
Having thus described my invention, what I claimas new, and desire to secure by Letters Patent, is
1. A conveyer-conduit having a curved portion provided with detachable means adapted to receive the impact of the matter being conveyed.
2. A conveyer-conduit having an elbow provided with a reinforcement located on the inside, on both sides of a medial transverse plane, and in osition to receive the impact of the matter eing conveyed. e
3. In a conveyor-conduit, an elbow reinforced within at the side having the greatest radius of curvature.
4. In a conveyer-conduit, the combination of a curved portion and a supplemental plate located in position to be impinged upon by the matter being conveyed.
5. In a conveyer-conduit, the combination of an elbow and a supplemental wearingplate located therein at that portion having the greatest radius of curvature.
6. In a conve er-conduit, the combination of an elbow an a concavo-convex wearingplate located within that half thereof having the greater radius of curvature.
7. In a conveyer-conduit, the combination of an elbow, a replaceable wearing-plate of concavo-oonvex form located therein at the side having the greatest radius of curvature, and means for securing said plate in position.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
HENRY J. PODLESK.
