Patented Apr. 8, 1924. UNITED -STATES PATENT OFFICE. LAVTRENCE V. FRALEY, OF CI-IICAGO, ILLINOIS, ASSIGNOR, BY -- L@IESNF, ASSIGNMENTS, TO STANDARD CONVEYOR COXPANY, OF NORTH ST. PAUL, XINNEBOTA, A CORFORATION OF MINNESOTA. PORTABLE CONVEYER. Application filed February 20,1920. Se-rial No. 360,112; -7'o alltt)Zto7n it mc,,y coq?,cem: Be it kriown that I, LANvRENcF, V. FRALEY, a citizen of the United States, residinb, at Chicago, in '@,lie county of Cook and State of Illinois, h,,ive, invented a certain new and useful Impi-ovement in Portable Coliveyers, of which tl-ie f ollowing is a, flill, concise, clea.r, and exact description, refereiiee being had to the accompanyina drawing.9 10 forminz a part of this specifiewtion. This invention relates to, port,,Lble cbnve37ers. Conveyers of this ty . pe are folind parti-,iilarly useful in transferring loose materials 15 such as dirt, gravel, -stone and the like over (,,omparatively short distances, that is, from one pipe to an adjacent pip6 or iiito a bil'i or other conveyer. They, -Lisually inellide a suitable conveying medium carried by an 20 elonoated frame supported iipon wlieels so that t, the conveyer may be re,,tdily rrioi,ed abotit a-Tid to ttie position desired. The general aim of the pi-esent ini@ention is to improve the construction and operatioii 26 of- Copveyer@ of this type. More specific,,tlly 6ne object of this inventioii is to so construct @he rec@4@i-@iiio- enl@ of the convever that it may be inserte@a into@ or pl,,i,ced in a most advantage I ous osition p 30 -vtitli respect to the pile of niateriai to be moved. Another object is to so construct the receivi-,ig end of the conveyer frame that, it ii,ill not jab into tl-,e gr6und and thus in35 terfere -",ith the ready movement of the ConVe37er from place to place. Aiiother object is to provide an improve(I conveyei- of sucli constriietion as to be proof ,o@,,.iinst loss of materiil cl@ie to leali,, cq t ole or 40 Ot', - li ellwise diivit-ig the passa. e of tl-ie mgte 9 i@i,il tl-ieretl-trougfi. Aiioth,-r obje&@ is to provide an adjustable siipport for fhe conITey(,r whereby the elevatioii thereof m,,i,y be varied at lvviii. 45 Aiiother object is to pro,vide an improi,e(I r,riea,ns for adjtistably stipporting the drum, over ivl-iieli the conve)Ter apron pa ses. ,,@pother object i@ to provide an improve(I oi-'Iiiiigg system for the drum. r3o Otlilov, (',bjects ,nd advantages will here,iaaftet "ippear. of thr@ inv,.liitior, are illustrated in the accompanyldg drawiiizs.

Each collar 48 is secured to a side plote 35 by meaiis of bolts 51 or the, like so as to surround the opening 46 therethrough. The screws 4:7 ,ire preferably arranged lengthwise of the conveyer and thus form a convenient n-ieans f6r obtgiiiing a proper adjustn,ient o'L the drum shaft 45 @vith respect to the conveyer belt.

When it is desired to gain to the interior of the @onveyer frame it is only necessary to remove the bolts 105 and s-wina, tlae plate do-wnw,,ti,;dly as indicated by @lie dotted lid-e position of Fiyure 16. In order to. pern-iit this swinging movement of the pl,.Lte the side m-rgins tliereof to tl-ie repr oi the pi-vot point tre cut a-vv,,ty to provide the iiecassary clearance. l@ Plate 40' n-ia be sectired to the lower sills 1.1' by rivets or bolts aiid extends preferably from the re,,trextreinity of the hinged plate 101 to the ends of the side plates '05' (see Figures 15 and 17). '5 c nThe top of the receiving end o the I o veyer franie is closed by nieaiis of a trough shaped meirber 36 b, the belt 23', and Ict belt supportiiig plate 39', as illustra'ued in Figure 16. The forward end of tl-ie tro@-dgh member 20 361, rests witbin a shalloiv seat 107 formed upon rear portion of the casting 33'. Member 39' is positioned below the belt 23' with its longitudinal edges extending to the irons I O' and lying upon the braelcets 108 to which 23 they are preferably riveted. The belt supporting pl,-tte 39' is secured in position by a@iy ,),ppropriate ineans such as angle brackets 108 secured to the side plates 35'. The purpose of the plate 39' is 20 to support the belt 23' at the loading point and thus prevent such ob sagging of the belt as might permit the escape of the material from the belt beneath the side plates 22' and into the closed end of the frame. ab Witliin the closed or receiving end of the conveyer frame the transverse members 16' are suppo:rted by means of angle brackets 108 secured to the side plates 35? (See Figure 17). The belt supporting roliers 20' 40 are supported upon spindles 98' which ftre some-what longer than the spindles 98 previously referred to. Spindles 98" extend through the a-ngle bars 99 and als6 through one of thE@ side plates 35? to the,outside of 45 the conveyer frame. The projecting end of the spindle is bent over as shown at 109 and is held in plice by any appropriate means such as a spring clip 110 secured at one end to the side plate 35". Thus in removiiig a 6o roller 20' it is only necessary to disengage the end 109 from the clip and withdraw the spindle 98'. It is obvious that t sijnilar clip might be employed to retain the other spindles 98 in 55 pl,,tce. In 'uhe present instance however cotter pins Ill are employed to prevent the reinoval of the spindles 98. Referri-ng to the rear or delivery end of the conveyer frame it -will be seen from 60 Figure 15 that the sanie is provided with side plates 58? in the form of ribbed castin,gs. A longit-Lidinal slot 63' is provided for slidably i-eceiving e, be,,tring block 64' formilig an adjus'uable support for the shaft 65 62'. The rear or upper conveyer belt drum (not shonvn) is pi-eferably keyed to this sh,,tft. kny@Lppropriate means such as an aiigle iron 59' iii,,t be, e -olo-ved to close the y Ml open eiid of the slot 63'. 11 Aii adjusliiig screw 66' screnved through To @-,n e,.ti- 6i' and ht)ving a rot,,ttable bearing iii the blocl@@ 64' foriiis ,L coiivenient iiieans for odj,,istinu tl-ic shift 62' to eftect the desireci Len,,@joii. in the coiiveyer bglt.
