juiy 7, 1953 s. M. MERCZIER FLEXIBLE COVER FOR BELT CONVEYERS Filed Feb. 21, 1950 //v VEN TOR; STANLEY M. MERCIEE.

Patented July 7, 1953 FLEXIBLE COVER FOR BELT CONVEYERS Stanley M. Mercier," Bexley, Ohio, assignor to The J eflrey Manufacturing Company, a corporation of Ohio Application February'ZI, 1950, Serial No. 145,504 4 Claims. (Cl. 198-228) This invention relates to a belt conveyer and an object of the invention is to provide such a conveyer with cover means to protect particularly material carried on the upper run thereof irom being blown away by wind or from becoming'wet during rain, and generally to afford protection to said material and the belt and including a flexible hood or cover adjacent the head or discharge pulley' which may be opened or thrown back to afiord access at this position.

Other objects of the invention will appear hereinafter, the novel features and combinations being set forth in the appended claims.

In the accompanying drawings:

Fig. 1 is a side elevational view of the head section of a trailing conveyer which incorporates the features of my invention; i

Fig. 2 is an enlarged side elevational view showing particularly the flexible hinged cover and associated protecting means adjacent the head shaft of the conveyer; and

Fig. 3 is a detailed sectional view taken on the line 3-3 of Fig. 2, looking in the direction of the arrows.

In Fig. 1 of the drawings there is illustrated a head section III of a trailing conveyer portion of a stacking system which incorporates the features of my invention. Certain features of the head section I are disclosed more in detail .in

my co-pending application, Serial No. 145,501,

entitled Conveyer Apparatus, Including a Portable Stacker and Connected Portable Trailing Conveyer, filed February 21, 1950, and in my application, Serial No. 145,503, entitled Belt Conveyer Head Section of a Stacking System, filed February 21, 1950. I

The headsection I0 includes an elongated generally horizontally extending frame II mounted on four power driven crawlers I2, two at the front and two at the rear, on opposite sides, by which the head section I0 is propelled and steered. Mounted on the frame II is an endless belt conveyer including a belt I3 carried on spaced troughing idlers I4. Thebelt I3 extends around a head pulley or drum I5 carried at the front of the frame I I and is driven by a plurality of drive pulleys I6.

Stacker systems of th type involving a head section, such as that 'illustrated,are generally employed out of doors where they are subject to the elements, including wind, rain, snow and the like, and consequently it is desirable to protect the material being conveyed, as well as the belt I3, from such elements. To this end, the belt I3 and particularly the upper load carrying run thereof together with the material thereon is preferably protected by cover means which, as shown in the illustrated embodiment of my invention, includes a relatively stationary cover II carried by the fram II which may be made up of a plurality of overlapping segments of corrugated sheet metal bent semi-cylindrical and placed over the upper run of the belt I3, with the bottom edges rigidly attached to the frame I I.

Forward of the head pulley or drum I5 is a hopper or shield I8 bent in a general U-shape, with two sides of the U on opposite sidesof the drum or pulley I5 and rigidly attached to the frame II. The shield or hopper I8 extends upwardly and has an open bottom extending into a turntable construction I9 disclosed in detail and claimed in my application, Serial No. 145,501, above identified.

The shield I8 carries an adjustable stone box 20 which is a generally V-shaped upwardly extending member having a material supporting bottom which extends to a transverse square rod 2I at its rear portion, said box being adjustably carried inside the shield I8 and being adjustable forwardly and rearwardly by machine screws cooperating with elongated slots 22, the forward and rearward adjustment being provided by nut and bolt adjusting means 23.

Material discharged over the head pulley I5 will be received, at least in part, in the stone box 20 where the material will build up, as suggested by the dotted lines 24, which acts as a cushion to receive large stones discharged over the pulley I5 and to take some of the shock thereof to reduce damage and wear which otherwise might be caused to the shield or hop-per I8 or other parts of the complete system.

Adjacent the forwardmost portion of the stationary cover I! there is an arched canopy 25, preferably of metal, such as sheet steel, which is attached to the frame I I and which extends into and has overlapping relation with a hinged flexible cover 26 which, in general, follows the configuration and construction of the well-known baby buggy or flexible top of an old style automobile or buggy. That is, the cover 26 has a generally arched top piece 21 which is transversely horizontal, terminating in a pair of generally upright side curtains, one of which is seen at 28, said flexible cover being made of canvas or any similar or desirable flexible material.

The cover 26 is supported on a plurality of U-shaped hinged ribs 29, the opposite free ends of which are pivotally attached to a bracket of the frame II on transverse horizontal axes, there To hold the cover 26 down in its protectingposition the forward corners of the cover 26 are preferably provided with tabs, one of which is seen at 3 I, with each of which a hold-down spring and chain 32 cooperates, one end of said spring and chain 32 being attached to a portion of the frame ll adjacent the shield 18, the other being removably attached to a tab 3|. the hold-down means 32 the removable cover 26 may be swung to its collapsed position by swinging all of the ribs 29 rearwardly about their pivots so that access may be had to the interior of the shield IS.

A belt cleaning device 33 of generally standard construction is also preferably carried by the shield or hopper 1,8 and cooperates with the belt I3 as it moves around the bottom of the head pulley l5.

Obviously those skilled in the art may make various changes in the details and arrangement of parts without departing from the spirit and scope of the invention as defined by the claims hereto appended, and applicant therefore wishes not to be restricted to the precise construction the head pulley to which the flexible cover extends.

2. In combination, an elongated stacker conveyer head section main frame and cover mech-v anism, said main frame being adapted to carry a pulley at one end over which the discharge end of an endless conveyer is trained, an upright shield having an open top and bottom carried at the end of said main frame adjacent said pulley for covering and protecting material discharged over said pulley by said endless conveyer, said generally upright shield being rigidly mounted to the end of the main frame, an inverted substantially U-shaped cover rigidly mounted upon said main frame and located to cover and protect material being conveyed toward said head pulley by said conveyer, a rigid canopy rigidly carried by said main frame-associated with said inverted U-shaped cover extending toward said pulley, a

collapsible cover extending from said canopyover By detaching 4 collapsible cover including supporting rib means carried by said main frame between said canopy and said shield, and disconnectable means for holding said collapsible cover in its pulley and shield covering position including tabs on said flexible cover and spring means acting between said tabs and main frame adjacent said shield.

3. In combination, an elongated stacker conveyer head section main frame and cover mechanism, said main frame being adapted to carry a .pulley at one end over which the discharge end of, an endless conveyer is trained, an upright shield having an open top and bottom carried at the end ofsaid main frame adjacent said pulley for coveringand protecting materiad discharged over said pulley by said endless conveyer, said generally upright shield being rigidly mounted to the end of the main frame, an inverted substantially U-shaped cover rigidly mounted upon said main frame and located to cover and protect material being conveyed toward said head pulley by said conveyer, a rigid canopy rigidly carried by said main frame associated with said inverted U-shaped cover extending toward said pulley, a collapsible cover extending from said canopy over said pulley and the top of said shield and having an edge overlapping the top of said shield, said collapsible cover including supporting rib means carried by said main frame between said canopy and said shield, and disconnectable means for holding said collapsible cover in its pulley and shield covering position.

4. In combination, an elongated stacker conveyer head section main frame and cover mechanism, said main frame being adapted to carry a pulley at one end over which the discharge end of an endless conveyer is trained, an upright shield having an open top and bottom carried at the end of said main frame adjacent said pulley for covering and protecting material discharged over said pulley by said endless conveyer, said generally upright shield being rigidly mounted to the ,end of the main frame, a rigid canopy rigidly carried by said main frame and located to cover and protect material being conveyed toward said pulleyv by said conveyer, a collapsible cover extending from said canopy over said pulley and the top of said shield and having an edge overlapping the top of said shield, said collapsible cover including supporting rib-means carried-by said main frame between said canopy and said shield, and disconnectable means for holding said collapsible cover in its pulley and shield covering position including tabs on said flexible cover and spring means acting between said tabs and main frame adjacent said shield.
