Specification of Letters Patent.

Application filed December 14, 1911. Serial No. 665,651.

To all whom itmay concern:

Be it known that I, ADELMER M. BATES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Loading Apparatuses, of which the following is a specification.

My invention relates to machines for conveying filled bags and particularly to a mafor conveying filled cement bags to a' Like parts are indicated by the same let-' ter in all the fi ures.

A is a ba ling machine operated from the motor 1 and adapted in this case to receive cement from the hopper A and to fill a bag A standing on the platform A. The machine is provided with means, in this case a pusher A, to push oil the filled bag onto the conveying apparatus and the machine may be adapted to simultaneously; fill a series of bags but should be timed or operated so that the filled bags are successively pushed ofit' of the conveyer. R13 are framing portions and supports for the various arts of my conveyer. This conveyer consists of the endless belt C running over end pulleys C, C and idlers C C C is a belt tightener roller movably supported on the screw bars C in the usual manner.

D is a chute'between the two' sides of which the bags are received so, that their fall is broken, but the proportions of the parts are suchthat enough of the bag will contact the belt so that the belt while traveling will carry forward with it in succession the bags discharged upon it. The details of arrangement of the belt and its several guiding and supporting and drivin pulleys is. of no material consequence an may be taken as here shown merely diagrammatic.

is a discharge apron 1pivotally attached to the frame portion at 1 projecting outwardly'beyond the end of the belt and is supported at its outer end when in use by the pivotally" attached leg E The upper end of the apron E is placed relatively h gh up on the dlschar e end roller, C? so as to obviate any consi erable drop of the discharge bag but when so placed there is danger that the somewhat loosely filled and always flexible or yielding cement bags will be caught between the apron and the belt. To obvlate this I. provide a discharge roll F suitably supported in arms F from the frame and driven by. means of the pinion F which meshes with the gear wheel F on the shaft F* which carries the pinion F which in turn meshes'with the gear F on the shaft F which is driven by the sprocket wheel F from any desired sourceof power. On the shaft F is mounted the discharge end roller C This discharge roll is Placed so as to prevent the catching of the bag between the belt and the apron and it eases the bag down from'the belt to the apron so that the operator can easily pick up the bags and drop them onto the truck which he manipulates within the car. 7

G, G are the arms of a stopping device. They are connected at their outer ends by the end G: which is inclined as shown to prevent the bags from riding up on it while it stops the bags for the belt on which they travel is smooth enough to run under them. The two arms 'G', G are pivoted at G G and associate with the handle Gr whereby the stopping device may be tilted in either direction, as indicated in Fig. 1.

G" is a stop to limit the motion of the stopping device when moved toward its position of idleness.

G is a rope attached to the lower end of the-handle G and passing forward-is attached to the hOOkG so that its outer end may be within reach of the operator so that the operator in the car when his truck is loaded orat any other'time when he so desires or when there are enough bags be yond the stopping. device to fill his truck can operate the stopping'device and check the flow of-bags until he is'ready to receive them "again without stopping the motion of the conveyer. 7

V In the modified form shown in Fig. 6 the discharge apron E is mitered as indicated at H and provided .with a pivotally mounted extension H which may'lie in the mitered portion of the apron in continuation of its may be omitted of course or varied without departing from the spirit of my invention.

The use and operation of my invention have been explained but may be briefly restated as follows; The ba chine is preferably adapte to successively discharge bags upon the belt and where such bags are heavy, as'in the case of cement, their fall onto' the belt should be eased-or broken in some such manner as suggested. The car which is to be filled having been properly placed on the siding opposite the conveyer, the operator throws the apron up into position and secures it there by means of the leg, the belt driving mechanism being now thrown into operation the belt be-. gins to travel in the direction indicated and it carries with it the bags which are successively fed to it, these bags being nottoo tightly filled with heavy and inert material,such, for example, as cement, although of course the apparatus is applicable touthe handling of bags of material other than cement. They lle upon the belt in a somewhat spread out condition. When they reach the discharge end of the belt they begin to pass over the discharge end roller and are received upon and drawn along by the small discharge roller. It will be understood that the peripheral velocities of the discharge end roller and the discharge roll are approximately the same. This roll car,- ries the ba overthe break between the apron and t e belt without causing it to be dumped .or turned over or disturbed in its ent-ly and in posit-ion and so it moves proper condition for handling, onto. the apron; Here it maybe picked up or downwardly moved by the o erator and be delivered to the truck. 1 hen the o erator finds his supply of bags sufiicient lbr the moment he will release the controller rope which permits the stopping device to 'fall from the position shown in dotted lines to the position shown in full lines in Fi s. 1' and 2. This arrests the flow of the liags and the beltslides' under them. Any kind of a suitable smooth surfaced belt may be used and I have even contemplated using a steel ribbon belt.. The-weight of the bags WQl1ld hold the belt on or adjacent to its supporting idle rollers notwithstanding the conveying maforward pull of the belt but of. course any other arrangement accomplishing the same result may be substituted. The stopping device having its stoppingend backwardly inclined to the line of travel of the bags can not get under the bags orlhave the weight of the last bag thrown upon it so as to make it impossibleor' difiicult for the operator to raise it whichhe will do by, pulling on the controller rope when he desires the feed to be resumed. The apron is pivotally mounted and provided with means for adjusting its annular position in order that the height of the discharge edge thereof maybe-adjusted to suit the convenience of the operator and in order that when it-is desired to move the loaded c'ar away and to move an empty car into line with theend' of the belt, this may be done by dropping the apron allowing it to swing outside of the line of the car. e

The invention comprises means for continuously moving successively discharged filled bags to a car or other receptacle means for temporarily arresting the flow or movement of suchbags and means for delivering them withoutany eat dr5p or fall, without disturbance oi v danger of their being pinched'between the belt and the receiving apron.

I claim 1. A filled-bag conveying machine .com.-. prising a conveying belt, a discharge apronwhose receiving. end is pivotally' mounted and. in close proximity to thebelt at the turn, and projects longitudinally beyond. the belt, and a small discharge roll lying over and adapted to close the ap between the belt and apron and inter-me iate their work ing surfaces so as to form part of the-surface over which thebags proceed. fromthe receiving end of .the conveyer to the dis charge end of theapron.

2. A filled-bag conveying machine coin-- prising a conveying belt, a discharge ,apron whose receiving end is pivotally mounted and in close proximit turn, and projects longitudinally beyond the belt, and a small discharge roll lylng over and adapted to. close the ap between the belt and apron and intermediate their workings'urfaces so as to form part of the surface over which the bags proceed from the receive ing end of the conveyer to the discharge end of the apron, and a stopdevice adapted to intercept the bags and hold them while permitting the belt-to slide under them.
