2 Claims. (Cl. 198-93) This invention relates to an auxiliary conveyor attachment, adapted to he mounted on a conventional elevator conveyor to deliver material there to.

It is a denite problem in the handling of gran" ular products such as small grains and the like to feed said material to the conventional elevator conveyor units. The grain is often sored in large bins, from which a large portion inf-.ist be shoveled in order to completely ernpty the bin.

It is an object of my invention to provide an auxiliary conveyor attachment, adapted to be mounted for vertical and horizontal swinging movement at the material receiving end of a conventional elevator conveyor for delivery or" material from a relatively inaccessible remote point to the elevator conveyor unit.

It is another object to provide an auxiliary conveyor attachment adapted to be connected to a conventional elevator conveyor and to extend a substantial distance horizontally outwardly from the lower material receiving end of conveyor.

It is still another object to provide an auxiliary conveyor attachment or extension for connection with an elevator conveyor and constructed in the form of an auger adapted to be driven from a source of rotary power to deliver material to the elevator conveyor, and having a removable hopper unit surrounding a portion oi said. auger to permit said auger to be used as a drag-out conn veyor as well as to receive the ilow or material through a restricted outlet into the hopper.

It is a further object to provide an auxiliary conveyor attachment provided with a removable 0 mounting connection for securing the delivery end of the auxiliary conveyor' to discharge inaterial into the elevator conveyor and having an upright mounting pin as well as a substantially horizontal mounting pin to permit swinging movement on. a vertical as well as a horizontal axis.

These and other objects and advantages of my invention will more fully appear from the rollowing description made in connection with the companying drawings wherein like r erence characters refer to the saine or similar parte throughout the Several views, and in which:

Fig. l is a top plan view oi my conveyor aitaohment, as horizontally mounted on corn/enn l tional elevator conveyor, and showing the outline ci the removable hopper in dotted lines and showing the attachment in horizontally swung position in dotted lines.

Fig. 2 is a side elevational view of my attachment with the hopper assembled thereon, and showing said attachment in inclined relation.

Fig. 3 is a transverse sectional view substantially along the line iii-3 of Fig. 2.

Fig. l is an exploded perspective view showing the connector mounting for the auger extension; and

Fig. 5 is an exploded view showing the parts of the hopper as removed from the auger extension.

As illustrated in the accompanying drawings, I provide an extension conveyor consist" g auger l fixed to a rotary shaft t whic is journalled in suitable bearings respectively mounted in end plates i! and lil. As best shown in Fig. 5, the forward portion of the auger l .is enclosed in a casing li and a pair of opposed hopper mounting members l2 and i3 are fixed at their forward ends to the rear portion of casing il and are mounted at their rear ends on the end plate it?.

A hopper designated as an entirety by the letter A is removably mounted on the mounting members l2 and I3. A bottom closure casing lil sliclably mounted on the flanges along the lower edge of each of the mounting members i2 and it to enclose the bottom oi the auger l. A pair of end closure plates l5 and lil are respectively connected at the forward and rear ends of the hopper. The end plate i6 may be removably secured to end plate lil as by suitable screws and the forward end plate i5 merely rests on the top of the casing il. A pair of side plates il interconnect the two end plates l5 and it and hold the forward plate lli against shifting movement. A divider and distributing member I8 having an inverted V-shaped cross-sectional contour is interposed between said end plates iii and i6, and is secured thereto by the brackets i9. it should be noted that the upper `portion of the hopper can be easily removed as a unit by merely removing the several screws along the upper flanges of members l2 and I3 and removing the retaining screws, if any, interconnecting end plates it and lil. The lower portion of cover lf3. is merely slid outwardly to remove the same from the lower flanges of the members i2 and i3. It should be noted that the end plates l5 and t-'e retain the lower cover section li in position, and prevent longitudinal shifting movement thereof by abuting the end portions thereof.

-A conventional elevator conveyor designated by the letter B is best shown in Figs. l and 2 and has a relatively small hopper 253 at the bottom thereof, from which the screw conveyor 2l carries the grain upwardly, A discharge outlet 2?! is formed on the forward end of the casing l i surrounding the forward portion of auger 'i for the conveyor extension on the lower side thereof, and discharges the material carried by the auger into the hopper 2t. A mounting connection for removably securing the discharge end oi the conveyor extension to a conventional elevator conveyor is provided as best shown in Fig. Li. This connector consists in a strap or mounting plate 23 having an upstanding pivot pin xed thereto. The mounting plate 23 is adapted to be rig idly secured to the elevator conveyor as by being rigidly anchored to the side walls of the hopper 2o at the upper portion thereof as by suitable screws and nuts. It will be seen that the pin 24 is not disposed at right angles to 'the mounting plate of strap 23, but is inclined relative thereto at approximately an angle of 20 degrees less than normal. Since the maximum angleof the elevator conveyor is approximately 30 degrees, the

2O degree angle is approximately an average slope,

and will position the pin 24 substantially vertically relative to the ground level to provide a substantially vertical axis on which the extension may be swung. A pair of sleeves 25 and 2t are in the form shown rigidly interconnected and the axes thereof are disposed at right angles, one to the other. The sleeve 25 is adapted to be received on the upstlanding pin 2li and a pin -27 is `provided to extend through the horizontally disposed sleeve 2G. A mounting bracket, such as the substantially Usshaped yoke member 28 is provided and is rigidly secured to the forward end 9 of the extension conveyor, as by being welded thereto. The two spaced parallel arms of the yoke 2S are connected respectively at opposite ends of sleeve 2t by the pin '27 and this oonnection permits swinging movement on a substanti'ally horizontal axis ofthe conveyor `'exto sion to permit optimum positioning thereof. In the form shown, pin 2'! `consists in 'a bolt with a head Na 'and a nut 2lb. Also, itgsh'oul'd be noted that there is no means, other than the weight of the conveyor extension, for retaining' the sleeve v223 on the pin 2?., thus permitting easy 'removal of the auxiliary conveyor.

The shaft t is 'driven by a drive shaft '29 connected at vits upper end to the power source 'for driving the auger '21, 'and has a tele'scoping portion to permit the length to be varied, and permit separation of the two telescoping sections. Any

suitable means, such as the polygonal male and female 'telescoping portions 'can be provided for producing the driving connection from one end of the shaft 2E to the other. A 'universal joint .to is interposed between shaft '29 andthe Vauger shaft o, and is disposed substantially directly above the pin Zal to facilitate the Vswinging movement both horizontally and vertically of the 'conveyor extension. A 'second universal joint 31 is interposed into the upper 'portion of shaft 29, and permits the forward end 'of the 'extension conveyor to be lifted 'to remove the sleeve '25 from pin 2d, and separate the two sections of the shaft 2i; to permit the extension conveyor to be bodily removed from the elevator conveyor B.

With my improved extension conveyor, it 'is a relatively easy matter to deliver granular products from remote and relatively inaccessible locations to a main elevator conveyor such 'as the conveyor B. If the grain is Vto be discharged through a restricted outlet, the hopper A is mounted on the rear portion ofthe auxiliary oonveyor extension, and is positioned below the restricted outlet to receive the grain discharged therethrough. 4This hopper is of materially greater size than the hopper 20, 4and is adapted to be positioned in substantially horizontal position with the free end thereof resting on the ground surface to keep the spillage 'at an absolute minimum. The divider plate I8 of the hopper evenly distributes the grain to the auger 1. The hopper A may be easily removed from the conveyor extension and the bare conveyor illustrated in Figs. 1 and 5 can be used merely as a drag-out conveyor by merely being positioned within the bin and substantially buried in the grain therein. The extremely simple mountingof the right angle sleeves 25 and 26 on their respective pins 24 and 21 permits the extension to be swung into substantially any desired horizontal position 'within certain maximum limits.

It will be seen that I have provided an eX- tremely simple, yet highly efficient, connection .for interconnecting a conveyor extension and a conventional elevator conveyor, which permits substantially universal positioning of the conveyor extension for optimum efficiency in delivering granular material to the elevator conveyorto facilitate loading thereof.

It should be noted that the ease of removal of the hopper A is an important feature of my conveyor extension, and that by simply removing the side panels I7 from the mounting members I2 `and I 3, the entire upper portion of the hopper can be bodily removed and the lower casing I4 easily slid off from the mounting members I2 'and I3. If the end plate vor panel IB is secured to end plate I0, then, of course, it will be necessary to remove any connections between said plates In and I6.

It will of course be understood that various changes may be made in the form, details, arrangements, and -proportions of the parts without departingfrom the scope of my invention.

What I claim is:

'1. An auxiliary conveyor extension comprising material transferring means, a driving conneotion connected with said transferring means and having a universal joint interposed therein, and adapted for connection to a source of rotary driving power, a mounting connection at the discharge end of said material transferring means including a mounting strap adapted for rigid attachment to a suitable mounting structure 'at the delivery end of said material transferring means, an opstanding pivot pin fixed to said strap and disposed immediately below the intersecting axes of the universal joint of said driving connection, a sleeve journalled on said upstanding pin and Apivotally mounted at the delivery end of said transferring means for swinging movement on a horizontal axis.

2. The structure set forth in claim 1 and said vertically disposed sleeve being vertically removable from said upstanding pivot pin, and a second universal joint in said driving connection to facilitate removal of said sleeve from the pin.
