ADRIEN GODIN, OF PARIS, FRANCE.

Application filed April 30, 1919.

To all whom it may concern:

Be it known that I, AoRmN Gonna, citizen of the Republic of France, residing at 10 Rue de la -Motte Piquet, Paris, in the Republic. of France, have invented new and useful Improvements in Elevators, Conveyers, and Cranes, (for which I have filed applications in France as follows: Sept. 14, 1917, Ser. No. 94,461, Feb. 20, 1918, Ser. No. 10,710, June 24, 1918, Ser. No. 10,997,) of which the following is a specification.

In hoisting apparatus of present construction with either grabbing or tipping buckets used for handling .heavy material such as ores, coal and the like the duration of each operation is greatly increased by the horizontal circular or rectilinear displacements of the bucket. Generally, the duration of a complete handling operation of a bucket is about double that of the mere hoisting operation.

- The object of this invention is to dispense with all horizontal motion of the bucket which thus remains in the same vertical line and hoists but does not convey horizontally. From such economy of .motion and time there results a considerable increase in the efliciencyof the bucket.

This invention consists in the combination with a hoisting apparatus embodying a ver tically movable bucket, or. two balanced buckets movable in opposite directions, of

vaconveyer located clear from the vertical path of the buckets and a receiving device adapted to receive the material dropping from the bucket and discharge the same onto the conveyer, said conveyer being so supported that it may be displacedhorizontally in all directions. This last fea ture is especially important since it permits for instance .to bring the conveyer to the most convenient position for operation and remove or displace the same when the operation is completed so as to clear the boat if the conveyer was supported on. aboat or entirely clear. the water if the conveyer is supported .on a gauntree crane or similar apparatus. V

Other features of the invention will be apparent from the following description.

In the accompanying drawings shown by v way of example, Figure 1 is a perspective view of the whole apparatus with the screen raised by means of chains and of a frame Specification of Letters Patent.

raised by the bucket. Fig. 2 is an elevation of the whole showing a difi'erent mode of ralsing the screen. Figs. 3 and 4 show an automatic device for retaining the screen, providedupon the edge of the hopper. Fig. 5 is a modification wherein the screen is done away with but where the hopper rolls so as to be able to come under the bucket at the t me when it is opened. Fig. 6 is an elevat1on of the apparatus suspended to the portal of a crane in a tidal harbor instead of being placed on the ship.

' In Fig. 1 the bucket or grab (6 which may be either of the automaticor tipping type is suspended from the hoisting chain or cables of an ordinary crane. Under the same, over the hold, is placed the improved auxiliary apparatus according to this in vention which comprises: the disappearing screen 1 turning about the horizontal axis 2 and its counterweight 3, the hopper 4 provided with a spout or flap 5 capable of moving about a horizontal axis 6; this spout can be either fixed or freed by means of the releaslng gear 7. The apparatus comprises also a continuous conveyer 8 which passes under the hopper and is used to carry away its contents.

The whole apparatus is fixed upon two beams 9 placed at suitable intervals and connected together by the tie bars 10.

These 'beams rest upon the ledges '11 of the hatchway by means of clamps 12 provided with two series of rollers allowing the apparatus to be moved along in two directions at right angles to each other above the hold.

The screen is propped up by the trestle 13 carried by the beams 9 upon which it is means of bolts or clamps so as to be able to have its position regulated.

lVhen the apparatus is in position for.

at such a pitch as to allow the material to rundown straight into the hopper,

7 the aid of a pull handle or by an assistant at hand, the flap 5 yielding under the weight of the screen drops down and allows the screen to fall and assume a vertical position in consequence of its, weight not being properly balanced by the counterweight. In this downward motion the screen is held by the chains 15; as the bucket descends the screen assumes its vertical position 1. The frame 14 which first followed the bucket is soon held by the chains 15 positioned at 15 and fixed to the screen and it parts with the said bucket in position 14 the bucket descending now alone to the bottom of the hold.

During the ascent all these movements take place in a'reverse sense the bucket first enters the frame 14:, carries it along and raises the screen l'until it meets the flap 5 which is first raised and then lowered while being automatically caught by the retraining gear. The engineer then has the bucket opened while being lowered; at the same time the screen l'suspended, therefrom comes to bear upon the flap 5 during the discharge of the material from the bucket.

Fig. 2 is a side elevation of the apparatus showing 'by wayof example one of the various devices which may be used to automatically raise the screen.

Said device comprises cables or chains 17 fixed to the screen 'base and wound upon a pulley 18 carried by the hopper, such pulley being actuated by, a chain 19 transmitting the motion from the pulley 20 capable of being. disconnected and mounted upon the axis of the front drum of the conveyer.

WVhen the screen assumes its working position under the bucket, it meets on its way up the fiap'5 and causes it to turn until it escapes, the counterweights 25 which have been moved toward the. bucket the flap along into its waiting position.

"lVhen the screen comes to bear on the flap it is stopped by the levers 2a owing to the 55 stop pieces 26 against which said levers abut. Y

screen is freed by acting on the pushpieces 27 the'stop pieces 26'are then freed the levers 24 which, under the action of the Weight ith j reen sume a r ZQn position corresponding to that in which the flap allows the screen to drop.- As soon as the screen is gone, the counterweights '25 bring back the flap to its waiting position.

The displacement of the hopper at the right moment may be carried outas for the screen--by the action of the bucket with the aid of a frame 29 and small cables or chains 30 passing over idle pulleys 31 and fixed to an arm 32 secured to the hopper. When in its loading position, the hopper is stopped by a retaining gear 33. As soon as the bucket is empty, this gear'is operated, close by or from a distance, to free the hopper wherein the screen is omitted, but I which, under the action of springs, of grave i near as possible to the hopper which should first have reached the retaining gear 33-v On account of the too great changes. occurboard or gauntree of a crane or placed upon supports 36 theheightof which may be suitably regulated ;,this beam is extended toward the ship by means of two arms37fspread apart and carrying the hopper and the screen trestle; on the other'side, thebeam reaches the wharf tracks whereon travel the cars requiring tobe filled'directly. To facilitate the drawing'in of the part which projects over the water, the'beam may roll npon its supports in, a sense perpendicular to the wharf; By means of cables orfchains 38, handled bya hand-winch or mechanically,

any suitable pointofits length onto inter- Having now described my invention what I claim as new and desire to secure by Letters Patent is:

1. The combination with a hoisting apparatus embodying a vertically movable bucket and means for operating said bucket, of a conveyer located clear from the vertical path of travel of the bucket, means for support ing said conveyer so that it may be shifted horizontally in all directions, for instance for the purpose of clearing a water way, and a receiving device adapted to either receive the material dropping from the bucket and discharge the same onto the conveyer or clear the vertical path of the bucket when the latter has discharged its contents.

2. The combination with a hoisting a-pparatus embodying a vertically movable bucket and means for operating said bucket of a conveyer located clear from the vertical path of travel of the bucket, means for supporting said conveyer so that it may be shifted horizontally in all directions, for instance for the purpose of clearing a water way, and vertically, for instance for the purpose of reducing to a minimum the vertical stroke of the hoisting bucket, and a receiving device adapted to either receive the material dropping from the bucket and discharge the same onto the conveyer or clear the vertical path of the bucket when the latter has discharged its contents.

3. The combination with a hoisting apparatus embodying a vertically movable bucket I and means for operating said bucket, of a conveyer located clear from the Vertical path of travel of said bucket, means for support-- ing said conveyer so that it may be shifted horizontally in all directions for instance for the purpose of clearing a water way, a pivoted, balanced and inclined screen adapted to either receive the material dropping from the bucket, or the vertical path of travel of the bucket and a receptacle adapted to receive the material from the screen and discharge the same onto the conveyer.

In testimony whereof I have signed my name to this specification.
