Speciiication of Letters Patent.

To all whom it may concern:

Be it known that I, BENJAMIN H. WRIGHT, a subject of Great Britain, residing at London, England, have invented -certain new and useful Improvements in Conveyers, of which the following is a specilication.

This invention has relation to conveyers, or systems of conveyers, for transferring from one place to another in a bottling establishment, warehouse, or elsewhere articles', goods, or packages of any description, such as boxes, barrels etc., hereinafter generically referred to as packages.

It has special reference to a feeding means for use as a part of or in connection with power conveyers, that .is to say, conveyers in which a power-actuated traveling means is employed to conduct the packages.

In its best embodiment, it isused with, or asa part of a conveyer, or' conveying sustem, in which the packages are fed aut'omatically to an elevator having a section arranged at an upward inclination along andupon the bed of which the packages are propelled by means of suitable traveling devices which engage the packages.

The objects and advantages of the present invention will fully appear from lthe following description, considered in connection with the accompanying drawings which exemplify what` I at present consider to be the best means for carrying my present objects into practical effect.

It is to be understood at the outset that my invention is not restricted to the illustrated embodiment, but that many changes may be made in the latter, and many means may be employed which are apparently widely different Vfrom those illustrated and described, without departing from the spirit of the invention, or the scope of vthe sub.-

joined claims.

In the accompanying drawings illustrating this preferred embodiment of the .invention:-Figure l is a plan view of part of a gravity conveyer and part of an elevator Vwith my package delivering means arranged between the same. Fig. 2 is a side elevation of the same parts. Fig. 3 is a cross section on the line 3-3 of Fig. 2, looking in the direction of the arrow. Fig. 4 is a cross section on the line L1-lief Fig. 2, looking in the direction of the arrow. Fi 5 is a detail view of a link of the lceder-chain.

Fig'. 6 is a detail view of a link of the conveyer-chain.

The same characters of reference desig-l nate the same parts in the several views.

A` designates what I consider to be the best type and form of power conveyer for Patented Feb. 20,1912.

use in a system of conveyers comprising my present invention. The illustrated conveyer A is an elevator of the type in Vwhich a bed or way is provided to support the packages and means are provided to ropel thepackages along and upon said d or way, the receiving portion a of which is arranged in an approximately horizontal plane while another of its sections (b) is arranged at an upward inclination. The bed or way-'here shown is provided with freely rotatable elements such las the rollers 1, hereinafter generically referred to as rollers and the illustrated traveling means comprise` a pair of endless chains 2, 2 arranged at the sides of the conveyer and traveling over suitably arranged sprockets, of vwhich those at the receiving end of the elevator are designated by the nuiiierals 3, 3. The chains receive their motion from these sprockets and are provided with package-engaging devices preferably composed of freely rotatable flights 4 arranged at intervals along the length of the chains and extending transversely of the conveyer from one chain to the other, and traveling above the wa l or bed of the latter.

These flights constitutethe best form of package engaging and propelling devices..

The special object of the present invention is automatically to prevent delivery of a package to the elevator or other power conveyer employed, until one of the't-raveling devices is in position properly to engage the package, thereby overcoming the well recognized .disadvantages incident to the use of these conveyers having nomeans for preventing the delivery of packages thereto until the traveling or propelling devices referred to can properly engage the same, or incident to conveyers havin no means for preventing movement of pac ages which are improperly engaged by the traveling devices. In pursuance of this object I, have provided what may. appropriately be termed a feeding mechanism B having an intermittently moved means, as C, for carrying the packages to the power lconveyer A with which the feeding mechanism is lassociated and combined. The movement ofthe carrying means C is at predetermined times such as to convey a package to the conveyer A when the traveling means of the latter are in position properly to `engage such packages, and the pauses in the movement of the feeding mechanism occur at those times in the travel of said means when a packageengaging device of the latter v would not properly engage a package. This, broadly, constitutes one of the features of novelty of t-he present invention.

Tn order that the feeding mechanism B may properly perform its intended function, it is preferred to operate it by or under the control of the traveling means of the power conveyer and this constitutes a further broad feature of novelty of the presentinvention. In further pursuance of the object of the present invention the traveling package carrier of the feeding means B 'comprises a series of freely rotatable elements, 10, hereinafter generically referred to as f rollers, and means are provided whereby these rollers are rotated during their travel toward the power conveyer with which the feeding mechanism is associated and combined. The packages thus derive from the rotation of the rollers l0 an impulse which moves them onward upon the rollers, in addition to the onward movement which they receive from the travel of the rollers toward the power conveyer. Provision is made for stopping rotation of the rollers during the pauses in their onward travel, whereby they exert no tendency to feed the packages ati such time.

The rollers 10 here shown are carried by a pair of endless traveling chains 11, 11 having links formed or provided with U-shaped projections 12, constituting bearings for the Journals 13 of said rollers. The chains 11 engagel and derive motion from sprockets 14 mounted upon shafts 15 arranged at the more supports 16 are provided near the delivery end of the feeding mechanism and are arranged in position to engage the rollersv 10. These supports perform the double function of a means for 'causing rotation of the rollers engaged therewith, when said rollers are traveling, and of preventing rot-ation of the rollers engaged therewith during the pauses of the travel of said rollers. They preferably are made of angle iron as shown.

The frame of the feeding mechanism may be of any suitable construction but T prefer to construct it of angle irons 17 extending longitudinally at each side thereof and provided with bent arms 18 to which are attached other angleirons 19 which support the upper or working run of the chains 11,11. The end supports are vertically arranged angle irons 20. Cross braces 21, attached to the angle irons 17, are arranged at intervals and adjacent thereto are tie rods 22 which support bent arms 23 which in turn carry t-he angle irons 16 upon which the rollers 10 travel.

It is preferred to extend the feedingmeans at an inclination downward toward the power conveyer A, and to arrange the supports 16 throughout a portion only of the length of the feeding mechanism, whereby the rollers l0 which are in the receiving portion of the feeding means, andin advance of the supports 16, are free to rotate at all times and will cause the packages temeva by gravity thereon toward the delivery end, thus further inducing a maximum extent of movement of the packages from' a minimum extent of travel of the package carrying .the receiving end of said conveyer is a traveler 25 having one or 'more projections 26 extending into the path of movement of the flights 4 throughout a portion of the travel of the latter. This traveler is preferably formed of an endless chain having suitable links formed or provided with the pro- L jections 26 referred to. This chain travels over sprockets 27 and -28 which are mounted on shafts 29 and 30 respectively. The

would be delivered upon the top of the flight.

'The shaft 29 carrying the sprocket 27 is suitably connected with the shaft 15 at the delivery end of the 'feeding mechanism, so as to drive the same. For this purpose'intermeshing gears 30 and 31 may desirably be employed. v

The receiving end of the conveyer A is preferably provided with a freely rotatable roller 32, or other suitable means, arranged in advance of its traveling mechanism and adapted to support the end of any package which may proJect from the carrying means of the receiving mechanism. v

llt will be apparent that in practice a complete system of conveyers will include a means for delivering packages to the feed atV sprockets 3 and' '27 are so arranged with l relation to each otherY that the flights 4 and l the projections 26 travel in diver-ging planes at the receiving end of the conveyer A, thereby becoming automatically disengaged from i each other when a Hight a is contiguous to ithe place at which it engages a package: f thus stopping the feeding of the package at such time and thereby preventing movement of a package from the feeding mechanism I 1 to the conveyer at a time when the package Aends of the feeding mechanism. Une orl Thesprocket 28 is so arranged with respect to the plane of travel of the ights 4r which are approaching their working lposition as i to conduct the projection 26 into the path of the' latter.

mechanism. This means may constitute a gravity conveyer such as is indicated at D and is 4shown more fully in Patent No. 714,432 granted to The Alve -Fenguson Company of Louisville, Kentuc for the invention of Benjamin H. Alvey,- which company also owns Patent No. 790,811 for the invention of Benjamin H. Alvey, aforesaid, relating to the elevator herein partially illustrated and in connection with which l prefer to employ my hereindescribed feeding mechanism.

Particular attention is invited to the fact that the feeding mechanism is arranged in the plane of the receiving portion of an elevator the conducting element whereof engages a wall of the packages, and that said feeding mechanism acts to convey each ackage to a position where its said wallvwill be engaged by the approaching package-engaging or conducting elements: as contradistinguished from constructions wherein loose and unpackaged material is fed to traveling buckets from a hopper having a reciprocatory slide for controlling its eed, and also from constructions wherein the thing con-l veyed by the feeding mechanism, whethe'r in the form of a hanger, a bucket 'or otherwise, constitutes a part of the apparatus. In this connection it'will be noted that the packages herein illustrated form no part of the conveying apparatus and are not of any special construction, and have no special means whatever by which they are suspended or otherwise carried by the power conveyer, the package engaging devices of the latter sim ly engaging a wall of the package, as alrea y stated; and that packages of various sizes and shapes and kinds may be conveyed without any alteration in the construction or in the size of the conveying apparatus.

It will further be noted that the device is particularly applicable to the class of elevators having an approximately horizontal section leading to and merging into the base.

of an inclined section and provided with a way or bed which supports the packages and further provided with flights forpushing the' packages over said way or bed, and that in combination with such a construction it affords the distinct advantage of preventing access of a package to the elevator at a time when the flight would improperly engage such package.

Having thus described the invention what I believe to be new and desire to secure by Letters Patent, is:
