DEVICE FOR STRIPPING STOCK FROM CONVEYER APRONS.
Application led September 14, 1922. Serial No. 588,235.
To all 'whom t may concern:
Be it known that I, FRANK L. FURBUSH, a citizen of the United States, residing at Westford, in the county of Middlesex'and State of Massachusetts, have invented a new and useful Device for Stripping Stock from )onveyer Aprons, of which the following is a specification.
This invention relates to a constantly operating device for stripping the stock from a wire or perforated conveyer used ina drier or the like.
The principal object of the invention is to provide an arrangement which will always remain in contact with the conveyer for stripping olf the stock. This has presented some diiiiculty in connection with the class of conveyers which run over polygonal drums because the ordinary strippers are sometimes out of contact with the apron that runs over such a drum. If the stock is not entirely stripped oft' it is carried back into the machine on the lower strand of theconveyer and the fans blow it around and get some of it into the steam coils. This not only ruins the stock but it also clogs up the steam coils and reduces their efficiency. VBeaters have been used heretofore `on a round drum at the end of the conveyer for this purpose and naturally work well because there is no tendency to lift the beater away from the drum.
One of the important objects of this invention is to modify the beater so that it can be employed with a polygonal drum. Another object is to so arrange a doifer apron that it can be attached to this type of machine instead of the beater.
Further objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying drawings, in which- Fig. 1 is an end lview of a drier apron showing a beater or stripper of my improved construction used in connection therewith for stripping the stock from the wire;
Fig. 2 is a side view of the same; and
Figs. 3 and 4 are similar views of a doffer apron used in the same way.
Referring first to Figs. 1 and 2, I have shown the invention as applied to a drier 10 having a wire or perforated conveyer 11 carried on two sprocket chains 12 which run over drums 13 shown as hexagonal.
One is located at each end although only one end' is shown.
F or removing the stock I have shown a rotary beater 14 having a plurality of beating arms extending therefrom and mounted .The outer pulley 18 receives power through a belt 19 from a jack shaft or motor, not shown. The inside pulley 2O which is fixed to it to rotate with it is provided with a belt 21 operating a pulley 22 fixed on the shaft 15 to transmit'power to the beater.
The beater shaft 15 is mounted in bearings 25 on arms 26 which are pivoted on the shaft 17 and free to swing thereon. It will be seen therefore that the pulleys 16 runing on the sprocket chains move out and in, in accordance with the rotation of the drum 13. At all times the beater arms, the ends of which run in the same circle as the pulleys 16, are in position to engage the conveyer and effectively remove the stock therefrom. The motion of the beater back Vand forth caused bythe angularity of the drum can take place as stated without changing the tension on the belt 21 and thus without interfering with the operation of the beater or stripper.
In the form shown in Figs. 3 and 4, the invention is shown as applied to the same kind k0f a conveyer which I have numbered in the same way and the power is transmitted also to the Vdoffer apron 40 in the same way through a belt 41. This doer apron 40 runs on two pairs of cylinders 42 the drier outside. A pulley is located on onel of the shafts 43 and thus the belt 4l drives the doffer apron continuously. In this case also there is an apron pulley 49 riding against the sprocket on the drum or the surface of the drum itself as in the other case to keep the intake side of the apron con stantly in contact With the conveyer as in Figs. land 2. The operation is the same and the results are the same except for the fact that this apron Works like any other doffer apron and conveys the stock away instead of beating it down from the conveyer.
From this it vvill be understood that I have provided means whereby the removing device for the stock can be kept in operative position at all times even though the conveyer' runs over a polygonal drum or even if it Were located on an irregularly acting device or an eccentric one. rlhis permits of entirely stripping the stock from the conveyer and keeping it from going back into the machine.
Although l have illustrated and described only two forms of the invention, I am aware of the fact that other modifications can be made therein by any person skilled in the art Without departing from the scope of the invention as expressed in the claims. Therefore, I do not Wish to be limited to all the details of construction herein shown and described, but What l do claim is l. The combination with a conveyer and a non-circular rotary device over Which the conveyer passes at one end, of movable; means adjacent to said rotary device for stripping the stock from the conveyer, said movable means being hung from above to rest against the conveyer as it passes over said rotary device and having a Wheel for regulating its distance from the conveyer arranged to move With the conveyer back and forth as it passes over at the end.
2. The combination with a drier conveyer and a non-cylindrical drum over Which it passes at one end, of a stripping device for removing the stock from the conveyer comprising a shaft, a rotary element on said shaft resting against the conveyer, and means for supporting said shaft freely in such position that it will act by gravity to siving back against the conveyer when moved outwardly therefrom by the motion of the conveyer itself.
3. The combination With an endless conveyer and a polygonal drum over which said conveyer moves, of a doer apron for removing the stock from the conveyer, a shaft over Which said apron passes and by Which it is moved and controlled, a pulley n said shaft, a belt and pulley for operat ing the pulley and shaft, and means freely hung to swing from above for supporting'l said apron in a position to bear against the conveyer on the drum by the action of gravity at all times.
4t. The combination with a conveyer' for fibrous material and a drum over Which it passes at one end, of an endless doffer apron for removing the stock from the conveyer comprising a shaft, a pairof Wheels on said shaft resting against the conveyer, and means for simporting said shaft freely in such position that the doffer apron thereon. Will be caused by gravity to swing back against the conveyer when moved outwardly therefrom by the motion of the conveyer itself.
5. The combination with an endless conveyer and a polygonal rotary device over Which the conveyer passes at one end, of movable means adjacent to said rotary device for stripping the stock from the conveyer, said movable means being hung freely above and from a point back of the endof the conveyer to rest against the conveyer as it passes over said rotary device and hav'- ing a Wheel for regulating its distance from the conveyer.
In testimony whereof l have hereunto affixed my signature.
FRANK L. FURBUSH.
