` To all whom it may concern.'

4Be it known that I, Monnls U. Bnnnnnrn, a citizen of the United States resldlng at (.in'cinnati l in the; county ofllamllton and 5 State of hio,. have invented certain new and useful Improvement in Conveying Systems, of which the following is a specificaltion.' A, f. l I

VThis invention ,relates to elevators and moreiparticularly toen elevator-- adapted to bein conjunction withliad as an element of a conveying system. y i

The purpose of the present invention 1s to provide an improved elevator of this nature 15 constructed to ebperate with' endless travelinglaprons arranged end to end in such manner.' that said aprons'and the elevator 'provide' means which safely and rapidly transfer filled bags or-ther aokages along a level of readily variable `ength and inA readily variable'directions and from said levelto a diiferent one, and which is adapted to ltransfer-siich packages from lwagons or cars' and pilethesame in any vpart of the room of "a Warehouse or other'place of stor? age or from suehstorage places'v to wagons or cars or fromone part of a room `to another part of the saine room or from'fone' roo'm to anothery roornon a different level. While it is intended to claim4 herein the elevator, I will describe in detail the construcltion and operation ofthe system as a whole because the marked Iadvantages of the elevator forming the'subject matter ofthis application can `best be appreciatedby aftl10r-V oughnnderstanding of the cOnditionsn-nder' Awhich itis used as well as the manner of using the same. The systenrof which this 'elevatorA `forms apart is characterized by. the

40 factsz .y i i Fi'rstythat it .compr1ses a serles of readily .separabler, and 'unitable movablei,.sections,K

each?` having a frame, anendlesstrveling ..ap1on'ashaf t which `extendslengthwise of shaft a1idtheapron 'adapted 'to' impart-:posi- 4 tive movement gto the4 ylattenin.tli'eg direction 'of the length of the shaft,` and 1'miv'feijylial` connections between the confrontingends of l the several sections. whereby oneoifsaidmAl shafts will 'be driven by another and will impart thel describedtraveling move-- menttothe apron of its section,"

the frame, drivngeonnections between the` the same to the foregoing sections, and hasl a. discharging slide, `tbeoileliverin `end of whlch is adjustable laterally as We l as ver# tically for delivering bags from the elevator to a predetermined place Within the range torage pile 'being'n of its adjustments, to a s built up by the system.

The parts are alsocharaoterized by features entering into the i details thereof,

whereby important advantages in respect ofA strength', effective ntilizationof power, port"-l ability, andI ease of disconnect-ions vof sec 1 tions and their assemblage into a system of the 'required length, extending in required `directions to and 'from any requiredplace,"

are secured, all as will hereinaftenfully ap` pear.

These slats serve as the support forthe filledbags whereby upon its rotation V1t will impart' travel-ing movement to the latter in the direction of the length of the shaft, and also has at its end anelement 840i a universal connection, the mate 8a of which is carried 'by theconti'guous end of the similar' shaft 5 of the next section A. This driving connection, for the type of apron conveyer herein illustratedyessentially includes sprockets 3 which are engaged by the chains 1' and are mounted on shafts i at. the oppositefendsoi gearing consistsv of a bevel gear 6 fixed 'on the shaft. 5 and a similar gear 7 'fixed on the 'contiguous'shaft 4 and intenneshed with the i gear 6. v-

AThe channel 42 is here shown'as formed by an annular' angle ring..r 32and a separate rmg 51 relatively disposed to close three sides ofthe channel, thefourth side being: formed by the wear plate.

In the exemplified form `'of the inventitm` both the plattormand carrier are thus of open annularform.

As already stated, the other end also of the elevator is mounted upon wheels (59) connected thereto in any suitable manner as by means of a frame having a member 60 which extends across the lower end of the trane, underneath the same, and "erticalmembers 61 which rise from the members 60 and are secured to the apron-freine members`25 and 26 at each side of .the elevatoxuv Suitobleprovision is made at this end of the elevator for takin upslaek in the chains'. The' means shown or this purpose comprise bearings 62 for the shaft of the sprockets, said bearings being slidably mounted in supthe same for uiding the bearings in their adjustments. h e bearings are adjusted by hand wheels 65, or other suitable means, mounted on rods 6 5' threaded in the supports.

The uprights 33 l'support a slide 66, through intermediate means which enable .the outer end of t-heslide to he raised or4 lowered and to be moved laterally, in order to direct the packages to'different predetermined-parts of the pile, within the range of its said adjustments.' The intermediate means referred to are herein shown as com.
