untonnmc No. 901,949. I Specification of Application flied January 22, 1908. Serial No. 412,214;
To all whom it may concern:
Be 1t known that we, FRANK ll. Brown and Farm ll. Brown, citizens of the United States, residing at Portland, in the county of l\lultnomah and State of Oregon, have invented new and useful Improvements in Unloading Apparatus, of which the following is a specification.
This invention relates to an unloading apparatus which has been particularly devised for use in relieving open ears or other analogous vehicles of their loads with convenience and expedition.
The apparatus is portable and readily reducible to compact form for movement from one position to another, and may be easily disposed adjacent to a car or other vehicle and quickly arranged for operation.
()ne of the most essential characteristics of this unloading a iiparatns is that the receptive extremity will follow the level of a load in a car or other vehicle to facilitate the en gagement thereof with bags, boxes and other parcels without requiring the operator to lift the bags, boxes or other devices up to the receptive extremityof the apparatus.
Another advantage is the expedition with which bags, boxes and other parcels may be handled at the delivery extremity of the ap paratus, especially in transferring such devices to a truck or analogous conveying means.
The invention consists essentially of a portable stand carrying a motive means and having a conveying organization movably attached thereto and freely adjustable to different elevations.
The invention also consists in the details of construction and arrangement of parts which will be more fully hereinafter specified.
In the drawings: Figure 1 isva perspective view of an unloading apparatus embodying the featuresof the invention and shown applied. Fig. 2 is a transverse vertical section through a portion of a car andthe conveying organization of the apparatus and the support for the stand of the app'ara- I tus, the stand being illustrated in side elevation and artially broken away. Fig. '3 is a detail p an view of a portion of the apparatus partially shown in'sgction. Figs. 4, 5, (3 and 7 are detail views of parts of the apparatus.
Similar characters of reference are emarrnaarns.

[ployed to indicate corresponding parts in the views.
The numeral 1 designates a stand, com prising essentially a base frame 2, having casters 3, uprights 4, holding a platform 5, inclined side supports 6 which are projected beyond the one end of the stand, and uprights 7 connected to the side supports and the base frame 2. The inclined supports 6 have a chute member or plate 8 confined therebetween and coinciding at its lower extremity with the rear end of the platform 5. The angle of inclination of the chute member or plate 8 is different from that of the supports 6, so asto cooperate with the platform 5 in the delivery of bags. boxes or parcels to the said platform with less abruptness, and also to have a part of the upper surface of the said chute member or plate elevated above the adjacent edges of the supports 6 to prevent contact and obstruction to movement of bags, boxes or parcels delivered over the said chute member and facilitate the direction of such bags, boxes or parcels fully on to the platform 5. The frame of the and as described also serves to conveniently support a motor 9 which, in the present instance, is shown of the gasolene type, though it will be understood that any suitable motor may be employed. It is preferred that the complete motor be disposed within the stand 1 to carry out the idea of portability of the apparatus, and to avoid dcpendence on driving power at a'dista-nce from the apparatus to effect an actuation of the conveying means which. will be presently described. The
suitable bearings on the uprights 7.
The foregoing organization forming part of the apparatus comprises an elevator frame 11; made up of upper and lower angle irons 12 and 13, forming tracks andconnected by side lattice work 14, to give lightness and strength to the structure. The horizontal flanges of the angle irons 12 and 13'are directed inwardly and are engaged by rollers 15 on the opposite extremities of a plurality of shafts 16, the latter being preferably rectangular in cross section to present flat surfaces for the reception of bags, boxes and other parcels. The; shafts 16 are arranged at regnlarflintervals and connected to chain belts 17, these belts being secured in such manner to the shafts that when the complete eonveyer comprising the shafts and belts is motor'9 a-ctuates the driving shaft 10 held in lot mg downwardly wheels in operation, the upper surfaces of the shafts traveling over the upper portion of the conveying apparatus will be free to receive bags, boxes or other parcels. The chain belts 17 travel over or engage the sprocket wheels 18 on a shaft 19, having bearing in the upper ends of the supports 6, and also travel around and ope atively engage sprocket at the opposite extremities of a drum 21 rotatably disposed in the receptive end of the. conveying apparatus. as clearly shown by Fig. 2. A partition 22 is held between the side membersof the elevator frame and adjacent; the upper angle irons 12 so as to prevent the bags, .boxes or other parcels engaging the several shafts 16 from project.- and interfering with the operation of the portions of the endless cha in belts 17 below. The partition 22, l'lltf'tfflltt. serves as a guard and extends almost the full length of the conveying organization. as
clearly shown by Fig. 2. The shaft It) is free to rotate in the upper ends of the supports (5 and to thus serve as a fulcrum means for the conveying organizatioi'i without in the least modifying its function as a driving element'for the endless chain belts l7 and shafts lti. The driving shaft 10 is provided with a sprocket wheel 23, and the adjacent end of the shaft 19 has a sprocket wheel 24 keyed thereto and of larger diameter than the said sprocket wheel 2?). Around the sprocket wheels 23 and 24 is a chain belt 25 engaged by a. belt tightener consisting of a small sprocket wheel 26 supported on the rear end of an arm 27 adjustably secured to one of the supports. The sprocket wheel 2-3 in its operative relation to the sha ft is conwill be hereinafter trolled by a suitable clutch 28, having an upstanding shifting lever 29, whereby the conveying apparatus may be set in motion or stopped as may be desired, without affecting the motor 5).
From the foregoing it will be understood that the conveying organization is freely movable or has a fulcrumcd connection with respect to the stand 1 through the medium of the shaft 19 engaging the upper ends of the supports (3, by means of devices which described, the object of this association of the parts mentioned being to permit the conveying apparatus to be raised or gravitate in relation to the height of the load, and thus facilitate the application to the receptive extremity of the con veying apparatus of bags, boxes'or other a car or other open vehicle. This adjustment of the conveying apparatus may be carried on without in the least affecting the association of the driving mechanism, and when the' apparatus is not w in use the conveying organization may be thrown over on the top,portion of the stand for convenience in transportation of the complete apparatus.
l l l 1:
There are many mechanical means for zip )lying the shaft 19 to the 231 projected through the ends of the sup,
ports (3 and formed with inner shouldered bearing extremities 32, and through these boxes the opposite extremities of the shaft 19 extend. The outer flanges 31 of the boxes are suitably secured against the outer sides of the supports 6, and the inner bearing extremities 3:? are engaged by eyes ill of coupling members 34 secured to the adjacent extremities of the opposite sides of the lifting frame of the conveying or; ;.-n1izati(m. as clearly shown by Figs. 3, 4., 5, (i and T. The coupling members 34- embody shanks 35 on which the eyes 33 are formed. and said shanks are secured by clips 36 bolted or otherwise secured to the adjacent extremities of the opposite sides of the elevator frame. By the. use of'thcse coupling mem bers the coi vcying organization may be swung in opposite vertical directions without interfering in theleast with the shaft 19.
The operatitin of the improved unloading apparatus s very simple. veying orgat-tizatiot has been properly disl oscd in a car or other vehicle to be unloaded, the motor is started and the convcyer proper actuated to cause the chain bolts 17 and shafts or bars 16 to move towards the upper ends of the supports 6. Bags, boxes or other parcels containing the material to be unloaded are individually placed on the receptive end of the conveying organization so as to engage at least one of the shafts or bars 16, the following shaft or bar engaging a portion of the bag, box or parcel as it comesaround into proper position. to thus insure cooperation ofa. pair of the shafts in elevating the bags or other devices. The receptive extremity of the conveying organization is so shaped that it may bear on the bottom of a car or vehicle without interfering with the operation of the chain belts and shafts or bars 16. When the bags or other devices arrive at; the upper ends of the supports ('3 they are caused to engage and slide downwardly over the chute member or plate 8 on to the platform 5, and fall with such rapidity on to the platform that an operator may grasp the moving bag or other device and with very little exertion direct it over on to a truck or other device disposed adjacent the stand, or the bags, boxes or parcels gravitating over the chute member 8 on to the platform 5 may be stacked or otherwise disposed at one-side of the stand. From time to time the stand and coi'iveying organization may be shifted longitudinally with respect to the car or other vehicle being unloaded to bring the receptive end of the conveying organization After the eon-' to thebags, parcels or other devices remain- 'in%in the car or-vehicle.
etween the attached" end of the conveying organization and the upper extremity of the chute member a roller 37 is mounted on the shaft 19 between the sprocket wheels 18, the roller being of such diameter or hav ing a projection relatively to the'adjacent parts that the packages, parcels or boxes de- ,vered from the conveying organization I .will be positively directed to the chute memher 8 by engaging the said roller 37. This roller is an advantageous addition to'the general construction of the apparatus, but
it vi ill be understood that its use is not nec- -essar1ly essential in view of the fact that the attached end of the conveying organization may be drawn close as may be desired to the upper end of the chute member.
Therefore, it may be said that the roller :5? is'an intermediate guiding means for directingthe bags or parcels from the conveying organization to' the chute member.
The improved unloading apparatus may also be used for transferring. the contents of one bin to another bin, or forother purposes where it may be found applicable, and by its use' the ope ation of unloading may bcicarried on with great expedition.
