Patented Nov. 20, 1934 UNITED STATES PATENT OFFICE FLEXIBLE ELBOW FOR PNEUMATI CONVEYERS 1 Claim.
This invention relates to a pneumatic elevator designed for use primarily in unloading cotton and conveying the cotton from wagons, and delivering the cotton to the gin.
An important object of the invention is to provide an elevator of this character which will permit of the free and unobstructed movement of the sections of the conveyer pipe, with respect to each other, thereby allowing unlimited adjustment of the elevator.
A still further object of the invention is to provide a metallic bearing at the elbow of the pneumatic elevator, thereby eliminating the use of the well known cloth or canvas boot usually employed in connecting pipe sections of a conveyer of this character.
With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise, embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawing: Figure 1 is a longitudinal sectional View through a pneumatic elevator elbow constructed in accordance with the invention.
Figure 2 is an end elevational view of the elbow.
Figure 3 is a sectional view taken on line 3-3 of Figure 1.
Figure 4 is a sectional view taken on line 4-4 of Figure 1.
Referring to the drawing in detail, the reference character 5 designates a pipe forming a part of the pneumatic conveyer, which connects with the elbow section 6, the pipe 5 being connected with the gin being fed with cotton.
The elbow section 6 is constructed preferably of sheet metal material, and as shown is provided with an internal groove forming a race for the bearing members or balls 8, which also fit within a groove formed in the main section 9 of the elbow. The elbow section 6 is also formed with a wide internal groove in which the packing ring 10 is positioned, the packing ring 10 being tted in a groove formed in one end of the main section 9, as clearly shown by Figure 1 of the drawing, thereby insuring an air-tight connection between the elbow section 6 and main section 9. f
Due to this construction, it will be seen that the main section 9 may rotate within the elbow section 6, so that the receiving pipe, to be hereinafter more fully described, and which is connected with the elbow may be moved to various positions to facilitate the unloading operation.
As clearly shown by Figure 1 of the drawing, one end of the main section 9 is substantially rectangular in formation, and is curved downwardly as at 11.
An offset portion 12 is provided on the downwardly curved portion 11, and provides a recessy for the packing ring 13, which closely engages the curved movable section 14 of the elbow.
This curved movable section 14 has pivotal connection with the main section 9, at l5.r Carried by the movable section 14, are curved angle bars 16, that are spaced from the upper wall of the movable section, as clearly shown by Figure 3 of the drawing.
Removably supported between the angle bars 16 and the inner surface of the outer wall of the movable section 14, is a curved wear plate 17 against which the material contacts, as the material is drawn through the elbow.
When the removable wear plate 17 becomes worn, it may of course be replaced by another wear plate, by merely sliding the wear plate from its position, and inserting another wear plate.
From the foregoing it will be seen that due to this construction, the curved section 14 of the elbow may swing in a plane atright angles to the movement of the main section 9, permitting the suction pipe, which is indicated by the reference character 18, to swing freely to the end that a proper adjustment may be made, to facilitate the loading operation.
A hanger indicated by the reference character 19 is connected with the downwardly curved portion 11 of the elbow, and provides means whereby the elbow may be conveniently supported and operated.
While I have shown and described bearings 8, as ball bearings, it is to be understood that it is within the scope of the invention to employ roller bearings, or any suitable bearings, in lieu of the ball bearings, embodied in this showing.
Having thus described the invention, what is claimed is:
A pneumatic conveyer comprising a conveyer pipe section having a curved end portion providing an elbow member, a curved elbow member fitted within the curved end portion, means for providing a fluid-tight connection between the elbow members, curved angle bars fitted within the curved end of the pipe section and spaced from the second mentioned elbow member, and a removable wear plate resting on the angle bars and engaging the second mentioned elbow member.
