of theelevator and is so correlated with a gravity conveyer or Other suitable feeding means E that packages may be delivered from the end of the latter to the receiving section. The propelling devices hereinbefore referred to successively rise at the eX-' tremity of the approximately horizontal section and in rising they traverse a plane which isintersected by the path traversed by .a package which is being fed to the re-.

.vided at its opposite sides with standards.

; or supports C which carry one or more spring arms D. It is preferred to employ three of these arms, as shown. These arms 1) are arranged longitudinally over the approximately horizontal receiving end of the elevatorat a height therefrom suflicient to clear packages which enter the elevator cm a ravity wa E. Their other, free, extremities d,-.wh1ch preferably are arranged at or near the base of the inclined portion Y of the elevator are bent down- .ward' as shown more clearly in Fig. 2 so as to give yieldability thereto and cause them to be in-t-he path of'the upper forward edge iof the packages. It will thus be seen that .if-the package is being moved by the propelling or pushing device while it is on top of'the' latter. instead of-immediately in front of the same, the downwardly bent portions dofthe spring arms will exercise a restraininfluence on the package sufficient to ho d it from'movement up the inclined portion of the elevatorwit h such propelling device: while they will yield to the force exercised by a package when the pushing or propelling device is behind the latter, and willihus permit thepackage to pass. Moreover, the described'arrangement of the spring-arms enables them to act to restrict e canting or tilting movement of any package to a dangerous or disadvantageous .in the length thereof.

extent which sometimes is caused by the rising and forward movement of a propelling device engaged with the bottom thereof.

In order to give rigidity to the rear portions of the arms and eflicicntly secure them in place, it is preferred to secure each toa support at a plurality of different places For this reason a plurality of standards, C, is secured at each side of the conveyer, and each standard is provided with a device which extends laterally .therefrom, over the floor or way, and to which the contiguous arm is secured. This device is preferably a cross piece C", which connects the standard with its com panion on the opposite side of the convcyer, and each arm is secured. to each of these cross pieces, at d, as clearly shown in F ig. 1.

Having thus described the invention what Ibelieve to be new and desire to secure by LettersPatent is 1. In a-conveyer having a bed or floor and traveling devices for propelling packages along the same, means arranged above the receiving end'of the bed or floor in such relation thereto as to permit a package to pass betweenit and the bed or fi00r,-said means being-yieldable upwardly toa package which is properly engaged with a propelling device and serving to restrain move- -ment of a package improperly engaged with a propelling device. f

2. In a conv'eyer having a bed or floor whose end at the receiving part of the conveyer is approximately horizontal, said bed or floor also" having an upwardly inclined section leading from said lapproximately and beIow the bed orfloor for propelling packages along the same, s id means traversing an upward path a the receiving end of the approximately horizontal portion of the bed or floor, and upwardlyyieldabl'e means arranged over said apfloor in such-relation to the package and bed or floor as to permit a package proprly engaged with a propelling d'evlce to be forced through the space bounded' above and below by said means and the bed or floor, respectively, and to restrain movement ofa package improperly engaged with a-propelling device. I

3. In aconveyer having a bed or way ages along the same, one or more arms arranged over the bed or floor in position to permit a package to pass beneath the same, said arms having yieldable extremities arrangedin the path of the upper forward edge of the package,

4. In a conveyer' having a bed or way and traveling devices for propelling packages along the same, and also with standards rising above its bed or way from each of its opposite sides, devices carried by the standards and projecting therefrom transversely over the floor or way, and arms secured to said devices and extending longiyieldable extremities arranged in the path of the upper forward edge of a package on the floor or way.

5. In combination with a conveyer having a bed or floor-provided with an approximately horizontal section at the receiving end of the conveyor and with an upwardly-inclined section leading from said approximately-horizontal section, means for propellin packages along the same, means for fee ing packages to the approxihorizontal portion, means traveling above tudinally over the floor or way and having proximately horizontal part of the bed or and traveling devices for propelling pack o traveling above and below the bcdor floor bed or floor, the propelling devices in their travel from the del1vering end to. the re- -;ce iving section of-the conveyer traversing a path'whi'ch is intersected bythe path of travel of a package to said receiving section, and upwardly-yieldable means arranged over the approximately-horizontal section of the conveyer, in such relation to the. ackage and bed or floor as to permit :1 pac ge whose rear end is, properly engaged with a propelling device to be forced along the bed or floor while it will restrain movement up the inclined part of the con- ,veye'r ofra package whose bottom is improperly engaged with a flight.

6. A conveyer having a bed or floor whose end at the receiving part of the conveyor is approximately horizontal. said bed or floor also having an upwardly inclined section leading from said approximately horizontal portion, means traveling above and be low the bed or floor for propelling packages along the same, said means traversing an 'upward path at the receiving end of the approximately horizontal portion of the bed or floor, ,means for feeding packages to the receiving1 section of the bed or floor in :1 Elaine wich is intersected by the path of vel of the propelling devices in the ris ingmovement-of the latter at the receiving end oi the conveyer, and means arranged over the bed or floor at the receiving end of the conveyer, for restraining canting or tilting movement of a package which,is improperly engaged with a propelling device.

A conveyer having a bed or floor whose end at the receiving part of the conveyer is a proximately horizontal, said bed or floor aso havingan upwardly inclined section leading from said approximately horizontal portion means traveling above-and below the bed or floor for propelling packages along the same, said means traversing an upwaz path at the receiving end of the appro'xiu-iately horizontal portion of the bed or floor, means for feeding packages to the receiving section of the bed or floor in a plane which is intersected by the path of travel. of the propelling devices in the rising movement of the latter at the receiving end of the conveyer, and means arranged over the bed or floor at the receiving end of the conveyer, for restraining canting or tilting Q movement of a package which is improperly means being yieldable.

8. A conveyer having a bed or floor whose end at the receiving part of the conveyer is approximately horizontal, said bed or floor also having an upwardly inclined section leading from said approximately horizontal portion 'means traveling above and below the bed or floor for propelling packages engaged with a propelling device, said along the same, said means traversing an upward path at the receivin end of the approximately horizontal portion of the bed or floor, means for feeding packages to'the receiving section of the bed or'floor in a plane which is intersected by the path of travel of the propelling devices in the risin movement of the latter at the receiving en of the conveyer and means arranged over the bed or floor at the receiving end of the conveyer, for restraining cant-ing or tilting movement of a package which is lmproperly engaged with a propelling devi e, said means having downwardly bent en 5 which are yieldable upward and are normally di'sposed in the ath. of the upper forward end of the package.
