SIZING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 740,180, dated September 29, 1903.

Application filed October 11, 1902. Serial No. 126,945. (No model.)

To all whom it may concern: Be it known that we, EDWARD RETTIGH, of Germantown, and MILTON E. PUGH, of Dayton, in the county of Montgomery, State of Ohio, citizens of the United States, have invented certain new and useful Improvements in Sizing-Machines, of which the following is a specification. Our invention relates to sizing-machines, and more especially to sizing-machines that will separate articles according to their length.

Our invention is particularly adapted for use in sizing tobacco-leaves, but may be used in separating like articles according to length.

The object of our invention is to provide a machine, automatic in its operation, that will do the work in a simple, efflcient, and accurate manner and with the least possible damage to the articles being sized.

\Vith these and other objects in view our invention consists of the constructions and combinations of parts hereinafter described, and set forth in the claims.

In the accompanying drawings, which form apart of this specification, Figure 1 is a plan View of a machine embodying our invention. Fig. 2 is a detail, partly in section, of the butting devices. Fig. 3 is a detail showing the relation of the inclined conveyors to the butting device and the means of driving said conveyors. Fig. 4: is a detail of the feeding device; and Fig. 5 is a transverse section of the bins, showing thesizing-rolls and carrier in said bins, taken on the line a: a: of Fig. 1.

Like parts are represented by similar letters of reference in the several views.

In the accompanyingdrawings, a represents a frame, and h and b cushioned rolls mounted on shafts suitably journaled in the respective ends of said frame. Said rolls are preferably made of flexible or pliable material that will cushion on and not bruise the leaves passing through same, or said rolls may be covered with such material for the purpose named. In the rear of the sizing-rolls we arrange a series of sizing-bins having partitions a, each bin being adapted to receive difierent lengths of the article sized. Extending from the rear of the sizing-rolls and projecting into said bins we provide carriers a which run upon rolls a and a extending longitudinally through said bins. These carriers are inclined upwardly at their rear ends, so that the leaves which travel tip first in passing from the carrier will bend downwardly and the butt-ends of the leaves, being stifier and heavier, will be thrown over, thus turning the leaves end for end and dropping them into the bottom of the bins, as shown in Fig. 5. The articles pass from the sizing-rolls to said carrier over a plate-0. At one end of said sizing-rolls and substantially at right angles with same wearrange feeding and butting devices. On a feeding-board c we arrange a casing c, in the bottom of which we provide a carrier carried by rolls 0 and c and we further provide in a housing 0 at the end of said casing two rolls 0 and 0", preferably formed of material used for the sizing-rolls, as hereinbefore described, said carrier-rolls delivering the articles to be sized into the butting-machine, which consists of a flexible conveyor ol,'having a link belt d, mounted on sprocket-wheels d and d said link belt and sprocketwheels being provided at each end of the butter and carrying between same partitions d", provided with bottoms, so that the rotation of said butter will carry the article to be sized within the compartments or bins formed by said partitions. A casing may be provided to cover said butter; but it is only essential that a casing such as d, extending about the lower portion of the butter, as shown, be provided.

Immediately underneath the devices just described and at right angles thereto we provide a carrier (1 the casing being open over said carrier, so that as the articles within the bins formed by said partitions pass over said carrier said carrier will butt their ends against a wall d Underneath the carrier d, as more particularly shown in Fig. 3, and extending at an inclination to the sizing-rolls b and b, as shown in Fig. 1, we provide a series of conveyers e. The ends of the conveyors e adjacent to the sizing-rolls are carriedby rollers journaled in the'frame a, said rollers not being shown, but each is limited in length to the width of the belt it carries, and the opposite ends of said conveyors are carried by a roll 6 common to all of them, said lastnamed roll being the driving-roll for said conveyers. The construction is such that the carrying portions of the belts between the individual rolls and the driving-rolls are free to ride on said frame, as shown in Fig. 5. It will thus be seen that as the leaves or articles come from the butting-machine with one of their ends adjusted against the wall (1 and are delivered to the conveyers they will be carried along by the con veyers until each leaf or like article is, according to its length,

- caught by the sizing-rolls and carried to the respective bins, as particularly shownin Fig. 1.

The conveyers may be driven in any suitable manner; but we have shown the same driven by a grooved pulley 6 which receives its power by a round belt from any suitable line-shaft, said pulley being mounted upon a shaft 6 which drives the roll (2 through a pair of bevel-gears 2 The upper sizing-roll is driven by-a pulley b which may receive its power by a belt from the same line-shaft as the pulley e and the carrier a is driven by a belt a", extending from a pulley b to a pulley a on the shaft of the roll 0. On the shaft of the roll a we also mount two grooved pulleys a and a one of which, a carries a round belt to a grooved wheel 01 to drive the sprocket-wheels d and cl of the flexible conveyer, said belt extending about a well-known form of idler-pulley, (not shown), and from the grooved pulley a we drive the carrier d by a round belt extending directly to the grooved pulley d of the carrier d On the shaft of the sizing-roll b we mount three grooved pulleys a a, and a, a having a round-belt connection to a pulley c to drive the carrier 0 a a round-belt connection to the pulley c to drive the rolls 0 and c and 0. has a round-belt connection about an idler-pulley (not shown) to a pulley f to drive a brush f. The brush f extends over the bins or compartments of the flexible conveyer, so that when the articles to be sized are fed to said flexible conveyor if for any reason one or more of them should be caught on the top edges of the partitions they will be swept off into .the compartments or bins. The extension d of the casing for the flexible conveyers catches the articles that are being fed and directs them into the bins.

The operation of the machine is as follows: The leaves or articles to be sized are fed through the feeding device into the compartments or bins of the flexible conveyer, and they are carried by the flexible conveyor across the carrier underneath the same, which is traveling at right angles to said flexible conveyer, so as to adjust one end of all the articles and deliver them to the conveyers, by which they are carried forward, and the conveyers being arranged at an inclination to the sizing-rolls the articles will reach these rolls according to their length and be gathered by said rolls and carried into separate bins, according to their length.

Having thus described our invention, we claim' 1. The combination with a frame and sizing-rolls, of a conveyer, the carrying portion of which is adapted to travel on the surface of a stationary portion of said frame, at an angle to said rolls, substantially as specified.

2. The combination with frame and sizingrolls, of a series of conveyor-belts, the carrying portions of which are adapted to travel on the surface of astationary portion of said frame at a uniform speed and at an angle to said rolls, substantially as specified.

3. The combination with a-frame and sizing-rolls, of a series of conveyor-belts operating in the same plane, the carrying portions of which are adapted to travel on the surface of a stationary portion of said frame at an angle to said rolls, and means to locate the articles to be sized on said conveyor-belts, substantially as specified.

4. The combination with sizing-rolls,of conveyers adapted to travel at an angle to said rolls, and means, including devices to move thearticles to be sized in two directions and deliver same to said conveyers, substantially as specified.

5. In a machine such as described, butting devices consisting of a series of bins running over a carrier which travels at right angles thereto, substantially as specified.

6. The combination with sizing-rolls and conveyers adapted to travel at an angle to said rolls, of butting devices consisting of a series of bins running over a carrier which travels at right angles thereto,substantially as specified.

7. The combination with sizing-rolls and feeding and butting devices arranged substantially at right angles to said rolls, of conveyers traveling obliquely from said butting devices to said rolls, substantially as specified.

8. The combination with sizing-rolls and a series of sizing-bins in the rear of said rolls, of carriers extending from said rolls and in clined upwardly to carry and drop the articles sized into their respective bins, substantially as specified.

9. The combination of sizing-rolls with sizing-bins in the rear of said rolls with carriers extending from said rolls into said bins, feeding and butting devices arranged at substantially right angles to saidrolls, and con veyers traveling obliquely from said butting devices to said rolls, and means to drive said parts from a common source of power, substantially as specified.

10. The combination with a frame and a' rollers for each belt at the other end of said conveyer journaled in said frame adjacent to said sizing-rolls, each of said last-named rollers being limited in length to the width of the belt that operates over it, whereby the carrying portion of the belts between the driving and the individual rollers ride on said frame, for the purpose specified.

11. The combination with a frame and a pair of sizing-rolls, of a series of parallel endless conveyer-belts of different lengths operating in the same plane at an angle to said rolls, a driving-roller at one 'end of? said conveyer common to all of said belts, individual rollers for each belt at the other end of said conveyer journaled in said frame and adapt- EDWARD RETTIGH.
