To all whom'z'tjhtay concern Be it known thatiI, HANS M. l-IANsoN,

a citizen ofpthe United States, residing at Mason City,i nthe county of Cerro Gordo and State of Iowa, have invented a newand useful Conveyer, of which the following is a specification. Thls lnv'entlon articles are being unloaded.

A further object of-jthe invention is" to provide a CODVBYBDWlllClI will be supported 7 throughout its length to eliminate sagging of the container, :to retard the movement lVith the foregoing and the details of construction hereinafter de-' conveyerconstructed in accordance with the their ends disposed in suitable; bearings formed in the 'guide bars in theextensible 1 section. Sprockets 34 are mounted on the 1 ends of the shafts 33 @and accommodate the: chain '35; This chain 35 also movesiover the r. sprocket wheel 37 mounted on theshaft: 17 i scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, maybe made within the scope OffWl'ltt-ll is claimed,-with-' out departingfrom the spirit of the-inven tion. l Referringto the drawings:

Figure 4 1s a plan view of the conveyer.

Referring 'toxthe drawings in detail, the: conveyer includes a supporting frame comprising vertical end bars 5 and 6 which bars are connected by the horizontally disposed" bars 7 [Adjacent to the upper endsof the bars 5 and 6 are inolinedibars 8, the bars 6 being relatively long as compared with the bars 5 tosupportthe bars 8 at angles.

At the upper ends of the bars 5 and 6 are arranged bearingsQ which bearings support has reference to conveyers and more particularly-"to"a conveyer especially 'designed'to facilitate the unloading of freight cars or the like, wherein heavy} other objects in view which will appear asthedescription proceeds, the invention resides in the GOV-1T1- bination and arrangementflof parts and in,

A movable plate 39 is pivotally supported at the forward end of the conveyer 36 and is held in position by means of the brace rod 40 so that material discharged at the outer end of the conveyer 26 will drop onto the plate 39 and be discharged into the wagon or vehicle positioned under the other end of means, and means situated in the space provided by the looping of said conveying element and cooperating with said frameto slide the same back and forth.

2. In combination with a fixedflconveyer, an extension conveyer comprisingia frame slidably mounted adjacent the fixed conveyer, a conveying element carried by said slidable frame and having a portion thereof looped downwardly away from said frame, a fixed drive means engaging the looped portion. of said conveying element and hav-. ing connection to drive said fixed conveyer, a rack bar on the lower portion of said slidable frame, and pinion means mounted within. the space provided by the looping of said conveying element and meshing with said rack bar for-moving the slidable frame back and forth. r i

In testimony that I claim the foregoing as my own, I have hereto affixed my'signat u re.
