WILLIAM WALTER HUDSON, OF SALT LAKE CITY, UTAH.

LOADEB CONVEYER.

Application filed February 18, 1925. Serial No. 10,100.

To all whom. it may concern:

Be it known that I, WILLIAM 1V. HUosoN,

I a citizen of the United States, and a resident of Salt Lake City, in the county of Salt Lake '5 and State of Utah, have invented certain new and useful Improvements in Loader Conveyers, of which the following is a specification.

My invention is an improvement in loader conveyers, and'it consists inthe combinations, constructions and arrangements herein described and claimed.

An object of the invention is to provide a conveyer which can be adjusted quickly and easily to conduct material to a given point from any point within a considerable area.

A further object of the invention is the provision of a conveyer of the character described which is light in weight, can be moved readily from place to place, and which therefore is particularly well adapted for use in amine or likeunderground place.

Other objects and advantagesbf the invention will be apparent from the following description, considered in conjunction with the accompanying drawings in which:

Figure 1 is a plan view of the improved conveyer,

Figure 2 is a side elevation of the con- Figure 3 is a fragmentary vertical section' through the conveyer, the view being taken substantially along the line 3-3 of Figure 4, and

Figure 4 is a'fragmentary vertical section taken substantiallv along the line 44 of Figure 3.

The conveyer embodying the invention comprises a lower conveyer unit or section indicated generally atl, a truck 2 on which the conveyer unit 1 is supported for movement along a track 3 or on any supporting surface, an upper conveyer unit or section 4, and a carriage 5 to which the upper conveyer unit 4 is swivelly attached, the carriage 5 being adapted to move long the lower conveyer unit 1.

The truck 2 comprises a pair of wheels 6 mounted on an axle 7 and preferably being flanged and spaced for rolling contact with the rails of the track 3. The track 3 may be of any standard gage. The frame of thetruck 2 comprises a base portion 8 rockingly supported on the axle 7. Standards are upstanding from the corner portions of the base and each standard com prises an upper section 9 and a lower'sec tion 10 adjustably'connected as at 11 so that the effective height of the standards can be varied within a considerable range. The

truck 2 also includes a pair of upper side supporting members 12, each of which is secured at its opposite ends to the upper end portions of the standards at that side 01' the truck by rivets 13 or like fastening devices. Side clamping plates-14 are secured to the side'supporting members 12, as by means of rivets 15, and extend above the level of the side supporting members 12 for engagment with lateral faces of the side members. 16 of the frame structure lower conveyer unit 1. The clamping plates 14 at the opposite ends of the truck are spanned by tie rods 17 which extend through alined openings in such clamping plates,

/ and have threaded end portions engaged by nuts 18 whereby when the nuts 18 are tight ened the upper end portions of the clamping plates at opposite sides of the truck will grip the lower conveyer and hold the lower conveyer against longitudinal and lateral movement on the truck. When the nuts 18 have been loosened, the lower conveyer 1 can be moved longitudinally on the truck within the elements set by the length of the lower conveyer, and secured to the truck in adjusted position on the, latter by means of the nuts 18 and the tie rods 17.

The respective side members 16 of the lower conveyer unit have alined bearings 19 at one end of the lowerconveyer for a shaft 20, and have alined bearings 21 at the other end of the lower conveyer for a shaft 22. Theshaft 20 is located at the head or delivery end of the lower conveyer unit, and

.is driven. by a prime m over,'not shown, with is an idler. -,A conveying belt 25 is trained about the rollers 23 and 24 and extends between the side members-16 of the lower conveyer and over carrying rollers 26 which are rotatably supported on cross rods 27 tions of the side members 16 at'intervals along the length of the lower conveyer.

The lower conveyer has side boards for retaining material against lateral displacement from the conveyer belt 25, each of the side boards comprising an angle iron 28 substantially c'o-extensive in length with the side members 16 and'having depending securing lugs 29 received in sockets 30 in the upper side of one of the side members 16 adjacent to the inner edge of the latter. The

angle iron 28 has extensions in the form of' strips -31 and 32 respectively attached to the flanges of. the angle iron. The strips 31 and 32-may be of leather or any other suitable flexible and durable material.

The upper conveyer unit 4 is similar to the lower conveyer 1 in construction and comprises a pair of side members 16' connected by cross rods 26 on which are rotat-ably supported carrying rollers 27'. The side members 16 of the upper conveyer have alined bearings 19' at the delivery end of the upper conveyer for a shaft 20 which is operatively connected in any suitableknown' manner to the drive mechanism of a prime mover 23* which preferably is a compressed fiuid motor. The side'members 16' of the upper conveyer have alined bearings 21' at the receiving end of the upperconveyer for a shaft 22 which carries an idler roller 24'. A conveyer belt 25 is trained about a driven roller 23' on the shaft 20 and about the idler roller 24: and passes across the carrying rollers 27. The bearings 19' preferably are integral portions of plates 33 which are secured, as at 34 to the end portions of the side members 16 at the discharge end of the upper conveyer unit. These plates have end extensions at 35, each formed with a vertical opening 36 adapted to be'placed in vertical alinement with an opening 37 in the corresponding lateral edge portion of the floor or base plate 38 of the carriage 5. A pivot pin 39 can be placed in the alined openings 3637 at either of the opposite sides of the carriage 5 for attaching the upper conveyer swivclly to the floor of the carriage 5. I

I The upper conveyer also has'side board arrangements corresponding to the side board arrangements of the lower conveyer. The parts of the side board arrangements of the upper conveyer have been designated by the same reference numerals primed as the like parts of the side board arrangements of the lower conveyer and it therefore is thought that no detailed description of the side board arrangements of the upper conveyer need be given herein.

The receiving end of the upper conveyer carries a scoop 40 in the form of a plate secured, as at 41., to the side members 16' of the upper conveyer.

The base 38 of the carria e '5 mounted on a pair of wheels 42 space apart f orrolling contact with theupper faces of the side members 16 outwardly of the lugs 28. The base 38 of the carriage has depending guid' ing, and retaining lugs 43 at opposite sides 1 thereof depending below the level of. the

side members 16 for engaging with the outer faces of the side members 16 to prevent lateral displacement-0f the carriage 5 from the side members 16 of the lower conveyer.

From the foregoing description of the va.

rious parts of the device, the operation there of may be readily understood. Thetruck 2 can be moved along the track 3 to a desired position and the effective height of the truck can be adjusted as. desired within limits by adjusting the length of the standards 9-10. The upper conveyer unit 4 and the carriage 5'can be moved as a unit along the lower convcyer to adjust the effective len h of the con-veyer as a whole. If desired, t e upper conveyer can be swung about the axis of the vertical pin 39 sothat material can be loaded from apoint atone side of the track. When the upper conveyerunit is to be swung laterally of the left hand side of the lower conveyer unit, the pivot pin 39 is placed in the opening 36 at the left hand side'of the upper conveyer unit and the opening 37 at the left side of the carriage 5. When it is desired to swing the upper convever unit to the right of the lower conveyerumt,

the pivot pin- 39 is placed in the opening 36 at'the right hand side of the lower convcyer unit and the opening 37 at the right hand side of the carriage. The floor plate of the carriage 5 is cut away as indicated at 44 in Figure 1 so that material discharged from the upper conveyor unit will fall onto conveying belt 25 of the lower conveyer unit and willbe discharged from the lower conveyer unit at the head of the latter into any desirable place. The scoop 40 may serve as a guide along which shovels may he slid to deliver material onto the conveyer belt 25 at the receiving end ofthe upper conveyer unit.

It will be obvious from the foregoingthat the invention provides a conveyor which can be used effectively in a very limited space and also in a space of considerable area to conduct material from any point within that area to a given point. The device is light in weight and at the same time is strong and durable.

Obviously, the invention is susceptible of embodiment in forms other than that which has been illustrated in the accompanying Jig-576,910
