194,096. Divided and 19, 1951, Serial N0. 252,
2 Claims. (Cl. 198-171) This invention relates to conveyors and more particularly to mine conveyors of the endless chain type.
An object of the present invention is to provide an improved mine conveyor. Another object is to provide an improved mine conveyor of the endless chain type having novel features of construction. Still another object is to provide an improved conveyor chain structure and improved conveyor chain driving means. These and other objects and advantages of the invention will, however, hereinafter more fully appear as the description proceeds.
This application is a division of my copending application ySerial No. 194,096, iiled November 4, 1950.
In the accompanying drawing there is shown for purposes of illustration one form which the invention may assume in practice.
In this drawing:
Fig. 1 is a fragmentary plan view illustrating a preferred form of the improved conveyor.
Fig. 2 is a vertical section taken on line 2 2 of Fig. 1, with parts shown in side elevation.
Fig. 3 is a plan view of the drive sprocket associated with the conveyor element of Figs. 1 and 2.
Fig. 4 is a vertical section taken on line 4-4 of Fig. 3.
Fig. 5 is a vertical section taken on line 5-5 of Fig. 3.
Fig. 6 is a transverse section taken on line 6-6 of Fig. 5.
Fig. 7 is a transverse section taken 4on line 'I-'I of Fig. 2.
Fig. 8 is a detail view illustrating the manner of engagement of the drive sprocket with the conveyor chain and its relation to the conveyor flights.
In this illustrative construction, as shown in the drawing, the endless conveyor is generally designated I, and includes a central exible drive chain 2 of a modified cable type having connected closed horizontal links 3 pivotally engaging linklike chain portions 4 secured to plates 5. The portions 4 have projections 6 fitted in openings l in the plates and these projections are headed over at 8 to secure rigidly the parts together. Certain of the plates 5 have secured thereto at intervals along the length of the chain, transverse conveyor nights 9, having right angle scraper portions I0 at opposite sides of the central drive chain. These iiights are adapted to move material over a plane surface S (Fig. 7) of a troughlike conveyor frame in the manner fully this application October 143 described in the application above referred to. A conveyor drive shaft II (Fig. 6) has a central sprocket I2 secured thereto and the teeth of this sprocket are adapted to enter the openings of the closed links 3 and engage at I3 the rear end surfaces of the chain portions 4. Secured to the shaft I I at opposite sides of the central sprocket I2 are side sprockets I4 whose teeth straddle the chain portions 4 and are adapted to engage at I5 the rear end surfaces of the closed links 3 at the opposite sides of the chain portions. The scraper portions I0 are spaced apart, as shown in Fig. 8, centrally to provide a space to permit access' of the sprocket teeth to the conveyor chain. The sprocket teeth are so staggered and are so constructed that any dirt which has access thereto may be freely discharged laterally. Thus, by the provision of this triple sprocket structure the conveyor chain may be effectively driven, While clogging of the sprocket with dirt, due to its novel design, is substantially avoided.
As a result of this invention an improved endless conveyor is provided having novel features of construction whereby its operation is improved. The novel chain structure and the associated drive sprocket provides an extremely eiiicient, non-clogging drive for the conveyor. -Other advantages will be clearly apparent to those skilled in the art.
While there is in this application specifically described one form which the invention may assume in practice, it Will be understood that this form of the same is shown for purposes of illustration 'and that the invention may be modified and embodied in various other forms Without departing from its spirit or the scope of the appended claims.
What I claim as new and desire to secure by Letters Patent is:
1. An endless conveyor for moving material over a plane surface, said conveyor comprising a central drive chain including closed links connected together, with every other link disposed in planes normal to said surface and the intermediate links parallel to said surface, as they pass over it, and transverse scraper nights secured to certain of said links disposed in planes normal to such surface and lying in transverse upright planes intermediate the ends of the links by which they are carried and the next adjacent links disposed in like planes and extending to the bottoms of such links, said chain adapted to receive sprocket teeth in the space between successive links in planes normal to such surface, and said flights having portions spaced laterally apart centrally to `provide a space to permit access of the sprocket teeth to the chain links.
2. A conveyor as set forth in claim 1 wherein a guide for the conveyor chain is secured to the top of said plane surface and extends upwardly into said space between said flight portions, said flight portions extending downwardly along the sides of said guide in close adjaceny thereto.
