CONVEYER.

Application led January 3, 1927. Serialrlo. 158,641.

This invention aims to provide -a portable onveyer and novel means forfraising and lowering the, conveyer, novel means being supplied for actuating the conveyer.

' It is within the province of the disclosure `to improve generally vand to enhance lthe util-ity of devices of that type to which the invention appertains.

With the above andV other objects in view which Will appear as the description kproceeds, the invention resi-des in the combination and arrangement ofparts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise. embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

`The machine includes a truck 1 compris-y ing an axle 2 on which ground wheels 3 are journaled. 4Standards 4 are disposed adjacent to the ground wheels 3 (Figure 5) and are secured to the'axle 2', the standards each comprising a pair of angle members or the like which are spaced apart (Figure 1) lto form yguide yslots 6, the constituent members of the 'standards 4being sustained by braces 8'from'the axle 2.l VA top' `bar 5 connects the standards 4 at the opposite sides of the machin-e, and spaces apart the constituent inem@ bers of each standard,y to form the guide slots 6. Sheaves 7 are-journaled on the 'ends of the'top barV 5.

A conveyer :frame-.9 is located'between the standards 4*' and `includes side plates 10 conof the motor nected to end members 11, bottomrbars 12v connecting the end members 11, angle bars 15 secured to the,y side plates `v10 and extended below the side plates, and truss work 14 at each side of the machine and joining the ,end members 11, the bottom bars 12 and thel angle'bars lvthat; are joined to the side plates 10. The angle bars 15 support a fixed platform 30, that is locatedE between the side plates 1 0, as seen in Figure 8. A support-ing member 16 is connected at 31 to thev Vertical flanges of the angle bars 15 4of the conve-yer frame 9 and moves in the guide slots 6` of the standards 4 which form part of the truck 1. Pulleys 17 are. journaled on the ends of the supporting members 16 for the conveyer frame' 9. Braces 18 are pivotally mounted at their inner ends on the axle 2, andare pivoted at their outer ends, as shown at 1.9,

to the bottom bars 12 of the conveyer frame 9. Y

Flexible;elements-20 are `secured to the endsof the top bar? 5: of the truck frame, and are looped about the pulleys 17 on thesupporting-memberlG of the conveyer frame 9, the flexible elements 'being' passed over the sheaYesZ and being extended, thence, downi wardly, to and arounddrums 21 (Figure 7 mounted onl .a shaft y22 which is journaled (Figure 4) lin the angle bars 15 of the con` lveyer frame, the shaft 22 extending into a box-like housing 24 (Figure 9') connected by angle brackets 25 (Figure 1)- to one of the bottom Vbars 12 of the conveyer frame 9.

A worm wheel 26 is secured to the shaft 22and is located within the housing 24, the worm wheel meshing with a worm 27, on a shaft 28 disposed at right angles to the shaft 22y and journaled in the housing 24. The shaftl 28 carries a beveled gear 29. that meshes with a pair of beveledpinions 32' 1105-.Y tatablevon a shaft 33 journaled in the lower partY of the housing 24.` Clutch members 34 are'splined at 35 to the shaft 33 to rotateV therewith and to, slide therealong, compression springs 36 being interposed between the pinions 32 and the clutch members 34, to hold vthe pinions 32 in mesh with a beveled gear 29. Thehubs of the ,clutch members 34 turn in :the forks 37 cfa U-shaped yoke 38 pivoted at- 39 to a ylever 40 vfulcrumed at 41 on the housing 24. At this point it is to be .observed that the houaing 24 is provided with filling plugs 42 or vthe like, so that oil can! be vintroduced into` the housing, lthe various driving elements ,shown in 'Figure working in oil, and being housed in, sothat they cannot catch the garments of an operator. Safety thus is promoted, and is promoted, further, because the shaft is located in a tubular casing and in a tubular casing 43, the casing 43 being connected to a gear housing 44 (Figure 2) and the casing 2" being connected to a gear housing 45 mounted on one of the end meinbers'll near to one extremity of the conveyer frame 9.'

- as connected (Figure 2) by a worm and Vpinion drive, anyy other suitable connection may be used at this point. i

The forward end of the shaft 33 is journaled in the housing 45, as shown in Figure 3. In the housing 45 and in a bearing 50 on the opposite side of the conveyor frame, is journaleda shaft 51. The shaft 51 is ,connected to the shaft 33 by a beveled pinion 52 on the shaft 51, and a beveled vpinion 53 on the shaft 33,as shown in Figure 3. There is a pair of sprocket wheels 54 on the shaft 51, a' pair of sprocket Wheels 55 being journaled on a shaft'56v carried by bearings 57 on the conveyer frame v9, the bearings 57, and the bearing 50, with the housing V45, being adjustable lengthwise of the machine, to tighten'up a conveyer embodying chains 58 engaged about the sprocket wheels 54 and 55, the chains 58 being connected by blades 59 adapted to move along the platform 30,

any suitable means, indicated at 60, being provided for shifting the shafts 51 and 56. It is to be observed that the conveyer frame 9 is open at the bottom and consequently, the blades 59 on the lower run of the chains 58 do not drag upon anything, friction being reduced. The numeral61 marks platelike extension-s prolonged' beneath the ends of the platform 30 and having curved flanges 62vengaged aroundthe shafts56 and 51. The extensions 61 are supplied with elongated slots 63 movable on securing elements 64 mounted on the end portions of the platform 30. The construction is such that when either of the shafts 51 "or 56 `is moved by the means indicated at 60, to tighten the belt conveyer, the extensions 61 will participate in this movement and will slide with respect to theplatform 30. The purpose of theplatform 30 audits extensions 31 is, ofcourse, to prevent the material from dropping downwardlywhilst the material is being advanced the blades 59 of the conveyer/chain.

Ordinarily, the clutches 34 are out of engagement with the beveled gears 32, as

tion from the shaft 33 to theshaft 51, and v the sprocket wheel 54 on the shaft 51 operates the conveye-r 58-459,'to advance the material along the platform 30, it beingpossible to disclose the conveyer frame9 andthe conveyer at different angles with respect to the horizontal, so that thematerialwill not only be moved horizon-ally, but vertically as well. Y v

By means of the lever 40 and the yoke 38 either of the clutch membersl 34 may beengaged with the corresponding pinion 32, thereby to impart direct or reverse rotation to the shaft 28 and parts driven thereby. When the shaft'28 is rotated, the worm 27 and the worm wheel 26 rotate the shaft 22 and the vdrums 21, the flexible elements 2() being reeled on the drums, or being paid oil' from the drums, depending upon whether direct or reverse rotation is imparted to the beveled gear 29 fromthe shaft 33. Noting the disposition of the flexible'element 2O (Figure 1) with respect to the sheaves 7 and the pulleys 17, it will be cleartliat the iiexi- Y i ble elements constitute means for raising and lowering the conveyerframe 9, the supporting member 16 moving in the guide slots 6 of the standards 4.

The gears 53 and 52 of Figure 3 run `in oil in the housing 45, adequate lubrication being provided and it being impossible for the gear members 53' and 52 to become jammed with foreign material, or be caught in the clothing ofi an operator.. A filling plug 75, indicated in Figure 7 affords means whereby a lubricant can be introducedl into the gear lhousing45.

In Figure 10 parts'hereinbefore described are designated by numerals previously used with the suiiix a. are done away with, the conveyer being in the form of a belt supported upon spaced rollers 101 journaled on' the side plates 10?, the platform 30 being omitted. f 'f vAs soon as the lever 40 is released, the
