SPECIFICATION forming part of LettersPatent No. 739,736, dated September 22, 1903. Application iiled .Tnly 2, 1902. Serial No. 114,050. (No model )l To @ZZ whom it may concern:

Be it known that I, HENRI SPEISER, engineer, residing at 51bis Avenue de la Republique, Paris, in the Republic of France, have invented certain new and useful Improvements in Machines for Sorting Articles According to Their Size, of which the following is a specification.

This invention relates to a machine for sorting articles according to their size, and which maybe used, for exam ple, for sorting oranges or cylindrical articles or those Which are almost ofregular form or shape.

The invention consists, essentially, in charging the articles to be sorted onto conveyers passing through a series of fixed openings, which become narrower, in combination with ejectors so operated as to throw out the articles left by the conveyers on the edges of the said openings.

The accompanying drawings will give by way of example a clear understanding of the invention.

Figure 1 is a sectional elevation on the line A B of Fig. 2, giving a back View of my machine for sorting oranges. Fig. 2 is a vertical section on the line C D of Fig. 1, and Fig. 3 is a sectional detail showing a modification.

The machine comprises horizontal' conveyers provided with troughs 1, extended across the machine and hung by means of pivots 2 on two endless sprocket-chains 3, mounted on either side of the machine on sprocket-wheels 4 and 5. wheels 5 is vdriven by means of a ratchetwheel 7, on which acts a pawl 8, carried by an oscillating lever 9, which in turn is operated by a pitman 10, attached to a toothed Wheel 11. The latter is rotated by a pinion 12, which is turned by means of a crank-handle, a belt-pulley, or other suitable device. At each revolution of wheel 11 lever 9 and pawl 8 are reciprocated, shaft b' and Wheels 5 being thusintermittingly turned, the troughs moving in the direction shown by the arrows in the drawings and each time a distance equal to that between the said troughs, so

' that each trough takes the place of that which The common shaft 6'of the lower transversal part 14, the height of which can be adjusted, by means of screws 15, so as to leave under the said transversal part an opening I of a determined width. The said table 13 is intended to receive the oranges to be sorted, which are being constantly brought in front of the opening I by an attendant. The inner edge of the-table is provided with a shutter 16, pivoted to a stud or spindle 17 and presenting an upwardly-extending fiange 18, against which come intocontact the o1'- auges passing through the opening I. Opposite the shutter 16 and Within the machine lies a fixed transversal part 19, which guides the oranges and retains the same when once received in a trough 1--that is to say, when the shutter 16 has moved compietely over into ment of the shutter 16 takes place when they pawl 8 is riding back on the teeth of the ratchet-wheel 7--that is to say, when the cups are stationary.

At the back of the machine are arranged a series of hoppers 29 to take the oranges out of the machine, each of the said hoppers comprising a transversal part 30, `which can be brought more or less nearer to the troughs by means of adjlisting-screws 31. Opposite the transversal parts 30 lie shutters 32, which serve both as stops and as ejectcrs. When the said shutters occupy the position shown in full line in the drawings, there exists between the same and the transversal parts 30 the openings Il III 1V, dsc., the widths of which gradually decrease from the top to the bottom of the machine and of which the edges lie or are located in about the middle of the intervals of the positions in which the cups come to a stop.

The lower shutter 32 is mounted on the shaft 26, and the other shutters 32 are mounted on the shafts 33, so connected to shaft 26 by means of connecting-rods 34 and cranks 35 that all the shafts, together with their shutters 32, oscillate simultaneously to take up the position shown in dotted lines in Fig. 2 and to return to their initial position. This double oscillating movement is produced at the same time as that of the shutter 16 when operated by the cam 20.

The operation of the machine is as follows: When the troughs 1 are moving, the shutter 16 is charged with oranges which are able to pass into the opening I, such oranges as are toolarge for the said opening being laid aside. When the troughs come to a stop, the shutter 16 begins to move over and transfers the oranges it carries into the trough 1, located between the said shutter and the aforesaid transversal part 19, filling the entire length of the trough, after which the shutter moves back into its initial position. Then the troughs are moved again, and when brought to a stop the next succeeding cup is charged with oranges, and so on. On the other hand, When the troughs are moving charged with oranges the said troughs pass through the openings II III IV, rbc., and leave on the transversal parts 30 and the shutters 32 such oranges as are unable to pass through the said openings. Then the troughs again come to a stop in the place of those which preceded them. The greatest oranges are thus retained above the opening II, and those of which the size gradually diminishes are retained above the other openings. Vhen the troughs are stationary, the cam 20 causes the shutters 32 to oscillare,

so that the oranges retained by them are moved up and thrown over the transversal parts 30 into the hoppers 29, Where they are separately gathered. The smallest oranges, which have passed freely through the last opening VI, are conveyed by the troughs l until the latter meet with the fixed bufling parts 36, which move the troughs over on their pivots, the oranges contained in the same falling under the machine.

Instead of the shutters 32 I may use, as shown in Fig. 3, the fixed transversal parts 32, located opposite the adjustable transversal parts 30, and separate ejector-bars 37, suitably operated.

bottom, substantially as specified.

2. A sorting-machine, comprising troughs mounted on endless chains, means for imparting step-by-step motion thereto, an oscillating feeder for the troughs, receivers arranged at one side of the machine, and the ejectors arranged at varying distances from the receivers, the spaces diminishing from the top to the bottom, substantially as specified.

3. A sorting-machine, comprising a frame, an endless conveyer having troughs, movable in the frame, means for intermittingly movving the conveyer, a feeder for the troughs at one side of the frame, receiving devices at the opposite side of the frame, ejectors opposite the receiving devices, the space between the ejectors and receiving devices gradually diminishing from the top to the bottom, and means for simultaneously operating the ejectors.

4. In a sorting machine, a frame, a feedingtable at one side of the frame, an oscillating shutter at the inner edge of the table, means for operating said shutter, the stop-bar in the frame and opposite the table, an endless conveyer movable between the table and bar, and sorting devices at the opposite side of the frame.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
