UNLoADER Foa eoNvEYnns.

To all whom it may concern.' n

Be it known that I, ANTON BnoTz, a citizen of the United States, residing in Sheboygan, in the county of Sheboygan and State 'of Wisconsin, have invented new and useful Improvement-s in Unloaders for Conveyers, of which the following is a description, reference 'being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in nnloaders.for conveyers and more part-ieularly to devices for unloading material from belt conveyers.

It is Qneiof the objects of this invention to provide an unloader for conveyer belts which may be adjusted to unload a portion of or all of the material conveyed by the belt.

A further object of the invention is to provide aconveyer belt unloading apparatus in which a plurality of unloaders may be positioned alongside of but at different points of a conveyer belt to discharge a predetermined amount of the material at said difierent points.

A further object of the invention is to provide an unloader for conveyers which may be actuated by frictional contact with the. conveyer belt and by the-material car' ried thereby.

A further object of the invention is to provide an unloader for conveyers which is in the form of a disk adapted to roll sidewise on the surface of the belt and beneath the material carried thereby.

l/Vith the above, and other objects in view, the invention consists of the unloader for conveyers and its parts and combinations set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which t-he same reference characters indicate the same parts in the several views Figure 1 is a plan view of the complete unloader shown in connection with a conveyor belt and in the operation of discharginga portion of the material carried by the belt; Fig. 2 is a side view thereof; Fig. 3 is a transverse sectional view: and Fig. d is a diagrammatic plan View of two of the unloaders shown unloading material from a belt at different points.

Referring to the drawing the numeral 8 indicates a conveyer belt of ordinary construction which is adapted to convey the ma- Speccation of Letters Patent.

terial 9 on the upper surface of its upper portion. 'The belt is supported on upper rollers l0 and lower rollers 11. A discharg disk 12 extending over the upper portion o1 the belt and one or more upper rollers and engaging the upper surface thereof is carried by a vertical shaft 13. The shaft is journaled in the arms 14 of the swing frame 15 and the swing frame is supported by and has its bearing in the standard 16 positioned alongside of the conveyer belt 8. The lower end of the vertical shaft is pointed and rests on top of an adjusting bolt 17 threaded in the lower arm to provide for adjusting the disk with relation to the belt. The swing frame 16 which may be swung horizontally to have the disk overlap the belt more or less is held in adjusted position by means of bolts 18 threaded in the standard 16 and entering the apertures 19 provided in the swing frame 15.

In order to discharge t-he material from the disk a delecting plate 20 is adjustably connected to the upper arm 14 of the swing frame and depends downwardly therefrom at an angle and its lower edge is positioned to just clear the upper surface of the disk and to deflect material olf the edge of the plate. The deilecting plate is provided with an upstanding slotted arm 21 and a bolt 22 extending through the slot and threadedinto the upper arm 14 serves to adjustably connect the deflecting plate to said arm.

In the operation of the unloader as shown in lligs. l, and 3, a portion of the material carried on the belt will slide on the edge portion of the disk and the frictional contact of the disk with the belt and the material will impart movement to the disk and the disk in rotating will carry the engaged portion of the material off the belt. When the portion of the disk carrying the material passes beneath the deflecting plate the said plate will deflect said material oil' the edge of the disk and as the material is continuously fed to the disk the operation will be practically continuous.

-lt is to be understood that the portion of the material which is beyond the plane of` movement of the disk shown will be engaged by one or more other similar unloading devices with the disks thereof overlapping the conveyer belt to a greater extent than the disks shown.

F ig. L1 indicates a belt being unloaded by 110 -to be understood that conveyer belt, said i With the belt to permit the material to be carriedthereby and unloaded at other points.

While the disk is shown as .rotated by trictional Contact with the belt and the material itinay be desirable in some cases to positively rotate the disks by a belted or geared source of motion and it is the specification and claims contemplate unloaders operating in .this manner.

AFrom the foregoing description it Will be seen that the unloader is very simple in construction and operation and may be adjusted to discharge all or a portion of the material carried by the belt at one point or at a plurality of points.

What I claim as my invention is:

1. An unloader for a conveyer, consisting of a revoluble disk journaled in a support and positioned to overlap a conveyer b'elt to receive material thereon to remove material carried by the belt.

2. An unloader for a conveyer, comprising a support, a frame adjustably carried thereby, and a revoluble disk journaled in the frame and positioned to overlap a conveyer belt to receive material thereon to remove material carried by the belt.

3. The combination with a conveyor belt, of unloading means therefor, consisting of a plurality of disks jonrnaled in supports located at dii'erentpoints alongside ot a disks overlapping the disk overlapping connection With a belt and each succeeding,`

V the belt to a greater extent than the preced- 'inw disk to remove material from said belt.

4. rI he combination with a conveyer belt, of unloading means therefor, comprising a plurality ot' frames adjustably located at different points alongside of a conveyer belt',

and disks journaled in said frames and positioned to overlap the belt, each succeeding disk overlapping the belt to a greater extent than the preceding disk to remove material from said belt.

5. The combination with a conveyer belt, of unloading means therefor, comprising a plurality of supports located at different points alongside 'of a. conveyer belt, frames adjustably connected to arranged to be swung in a horizontal direction, and disks journaled in said frames and positioned to overlap the belt, each succeeding disk overlapping the belt to a greater extent than the next preceding disk to remove material from said belt.

6. The combination with a conveyer belt, of unloading means therefor, comprising aplurality ofsupports points alongside of -a conveyer belt, frames adjustably 'connected to arranged to be swung in a horizontal direction, disks journaled in said frames and positioned to overlap the belt, each succeeding disk overlapping the belt to a greater ex- -tent than the next precedingA disk to remove material Vfrom the belt, means` for adjusting ,the height of the disk with relation to the belt, and a detiecting plate adjustably earried by the frame and positioned to deiiect the material ofi of the disk.

7 An unloader for a conveyer, comprising a support, a frame swingingly carried thereby and provided with projecting arms, means for locking the frame in a xed position, a vertical shaft journaled in the arms, means for adjusting the shaft vertically, a

-disk carried by said shaft, a detlecting meniber carried by the frame and extending above the disk, and means Jfor adjusting the vertical height otl said delieclini,r member.

ln testimony whereof, l athx my signature, in presence of tivo witnesses.
