Zurich, Switzerland, a corporate body of'SWitzerland Application July 23, 1948, Serial No. 40,294 In Belgium February 6, 1948 It has already been proposed to construct apparatus which are intended to pick up and disvery bulky, heavy and diicult or complicated to manipulate. Others make use of a pick up member which is given a vibratory movement of great 4frequency and small amplitude (800 vibrationsv per minute for a movement of a few millimetres, for example). This movement is produced by unbalanced arrangements or the like!- 'Ihese latter apparatus in particular have the serious'drawbackv of becoming limp when the oscillating' member comes up against blocks, engages a compact material or when the shovel is too heavily loaded, that is to say that in these cases, the amplitude of the vibrations decreases owing tothe difliculty of the work, up to the point-of stopping the apparatus.

Furthermore, since for all these apparatus the discharge of the materials picked up is only effected in one direction, generally in the direction of the longitudinal axis, it is often diiiicult to adapt the apparatus suitably to an existing general organization for the removal of materials from a yard or from a mine level.

The present invention has for its object an apparatus for picking up and discharging materials by means of a vibrating chute, which can be used for all materials in heaps and in all yards, storage dumps, or mine levels.

stoping and loading.

The I apparatus according to the invention comprises a chute terminating in a shovel, and the body of which is positively set in vibration, the reaction of these vibrations on the frame of the apparatus being neutralized by the vibrations in opposite phase of a body having a mass equivalent to the rst one. It is thus possible to lighten considerably the frane of the apparatus.

The equivalent mass may be formed by a portion of the chute itself, in which case said chute is divided along its length into two portions of equal masses.

It is also possible to use an independent balancing mas's which may be provided with engaging tools for disintegrating the material to be picked up. In this case, the apparatus is suitable for working in a level, for' example for directly boring the rock of said level.`

a The frame of the apparatus may be supported by wheels, endless tracks orskids and said apparatus may be self-powered or connected to a source of power. v L

Some of them are The apparatus can furthermore be adapted to effect 2 Since the vibrating chute effects the horizontal movement and the lifting of the material, the same may be taken up directly at the outlet of said chute by a preferably continuous conveyor. The problem of mechanical picking up as Aa whole is thus solved by:` u

An action which prepares the material for picking 11p, v

An assembly of simple the picking up operation proper,

A device of great flexibility of installation and working for discharging the material picked up. Y l

The connection of the apparatus to the general device for removing materials from the yard or from mine levels (conveyor belts, oscillating chutes, wagons, movable elevators, etc.) is preferably effected/by means of an intermediate conveyor such as a loading device with chains or belts. Saidintermediate conveyor may advantageously-be pivotally connected by one "of its' ends to the rear portion of the apparatus and by the other end to a carriage which may carry the control station of the apparatus and of the conveyor. These pivotal connections en able very numerous relative orientations to be obtained, whereby the apparatus can be tted to any system for discharging materials.

The ensuing description made with reference to the accompanying drawing whichis given by way of a non-limitative example, will make it clearly understood how the invention can be carried out, the peculiarities 'which'become ap parent both from the ldrawing and from' the text forming, of course, part of said invention.

Figs. -3 and 4 respectively show an velevational and a plan view of an apparatus of this type, connected toa continuous conveyor, operating in a level. l

Fig. 5 is a diagrammatic plan of the apparatus for Figs. l and 2.

Figs. 6 and Tshow the outer ends ofthe bulers.

Fig. 8 shows a detail of the invention.

In the central portion of the apparatus shown in Figs. 1 and 2 and extending along the whole length thereof vis mounted a vibrating 'chute l whichl is slightly inclined with respectgto the horizontal. The front end 2v-which engages the material to be picked up widens outin' thei'shape of a shovel, the rear end 3, which is cutaway into a quarter circle,l forms a discharge lip;` the bottom li is provided wthgprojections .which and rugged members forl are suitably shaped and distributed to facilitate the feed of the material.

Two links 6 near the front and two others 1 near the rear are pivotally connected, on the one hand to the frame 8, on the other hand to the vibrating chute, and ensure the suspension of said chute.

The suspension links 6 and 1 form' a well-de'- ned angle with the slope of the chute so as to insure the feeding of the material owing to the vertical vibratory component action, thus avoiding complicated mechanisms currently used for driving vibrating chutes which operate ntl'i'roiigh the effect of the variations of the acceleration' between the to-and-fro strokes.

Two horizontal connecting rods 9, the Ysmall ends of which are pivotally connected to the vibrating chute, have their big ends mounted on a crankshaft IG: said crankshaft transmits the' vibratory movement to the chute l by a direct and positive mechanical action. Y lThe ro'tation'of the crankshaft Ill is' obtained by means of two gear trains, one 4a spur-gear' trai-n I I, `the other Na bevel-gear train l2, which are idriven by V"a motor i3 provided with a iiy- Wheel I4, the mass of which 'ehables the apparatus tow -ove'rcome the momentary difculties of its operation which are due to the load of the shovel `for exampleg The balancing `of the oscillations of thechute i is'effected 'by thev masses of two counterweights f5`which--are arch-shaped and to the feront ends of which are keyed two buiers 1S terminating domed or pyramidal surfaces il or surfaces are'deected from their axes, if desired with," inted r'sharp bits according to the pui'- psefoi'whichgthe apparatus is intended and the naturefof the materialto be 'picked up.

"links la, and two 'other 1ih1 je se, which ai? pivotally connected on the yene hand'to the fr 'rie '8 and on the other hand tothe countere weights 15, provide the suspension for said ccunterweights.

Two' horizontal connecting "rods 20, the `small ends y"of which are pivotally connected to the ehtevveights `l5 have their big' ends mounted n the crankshaft lil; said crankshaft transmits" the vibratory movement to the counterweights l5 by a direct and positive mechanical act-ion. The mounting of the linksv 9 and 2s in phaseopbosition effectsthe balancing of the two vibratory ri'oveih'ents'. Thus the counterweight which is necessary 'for balancing the chute i's'u'sed feras; sisting in the'work-'of cutting the material.

Figs. 1, 2, 3, 4 shovve. frame a supported by Wt'vvo identical endless track carriages 2 I, one on the right, the other on the left f the apparatus. VEach of. said carriages is adapted' to transmit tp the endless track 22 the necessary movement for propelling it by the'ac tion of asuitably chosen motor 23 by means of la bvlfgear'and Worm transmission 23a.

'ihe fra me 8 is connected to each of the carl iia'gleslj by the rearhoriz'ontal spindle 26 of the roller s of vthe endless tracks and by Iwo small Vifiydaulic jacks 25, the stroke of which is used forfadjusting the height of the shovel 2 of the oscillating vchute Vrelatively to the ground.

The apparatus is `therefore =`suitable for all vsizes'of grains, either 'separated'o'r mixed. The positive mechanical control of the vibrating chute produces, independently of all the reactions of the material to be picked up, oscillations of which the frequency may be between 500 and 1,0()0 vibrations per minute, and the amplitude may reach 25`millimetres. The simplicity of the mechanical members, their eicient protection, yenables Ythe apparatus to be used in all yards' and storing premises; furthermore, its

A n example of such al use is shown in Figs. 3

and 4.

An illuminatingY device by means of oodlights my be Provided for using the apparatus in mine positely located crank-pins of the crankshaft, which themselves vibrate in opposite directions and balance one another. The frame may be mounted on skids or on wheels which can be orientated or not; in this case, the orientation of the apparatus is eiTected by shifting it by means of a miners bar.

'I'he two-element loading chute may supply either an elevator, or a conveyor that loads a stationary conveyor, or a mine-car.

It is also possible to use the apparatus directily as a cutting and loading tool in coal mines for example. In this case, the counterweights I5 which balance the vibrating chute are provided with a series of bits forming a chisel, which are located vertically above one another and which detach the coal in situ, producing a kind of vertical nicking and making the coal fall onto the vibrating loading chute.

The whole apparatus may in this case be mounted on a Sledge and hauled into the face by a winch xed to the top of the face or provided on the machine.

It is obvious that modifications of detail may be made in the apparatus which has just been described, in particular by substituting equivalent technical means, without thereby exceeding the scope of the invention as set forth in the appended claims.
