CLARENCE KEMBLE BALDWIN AND THOMAS RoBINs, .IR..'OE NEW YORK,

N. Y., AssIGNORs To THE ROBINs CONVEYING BELT CO., A OORPORA- 'IION OF NEW JERSEY.

CONVEYER.

To all whom it may concern:

Be it known that we, CLARENCE KEMBLE BALDWIN and THOMAS ROBINs, Jr., citizens of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Conveyers, of which the following is a specification accompanied by drawings.

Our invention relates, broadly, to conveyers, but more particularly to portable conveyers of the type utilizing a continuouslytraveling conveyer-belt.

The objects of the invention are to improve upon the construction of portable conveyers and afford provision for moving the delivery end of the conveyer in all directions in a horizontal plane and also in a vertical plane. v

Further objects of our invention are to enable the material to be delivered evenly and rapidly to 'the conveyer-belt when a belt is used without danger of damaging the belt 'and also to equalize the weight of the parts of the driving engine or motor on the frame of the apparatus. 1 Further objects of our inyen-tio'n will hereinafter appear; and to these ends our invention consists of apparatus for carrying out the above objects embodying the features of construction7 combinations of elements, and 'arrangement of parts having the general Iiereinescribed and claimed in this speciication and shown in the accompanying drawings, in Which- Figure 1 is a side elevation of one form of apparatus embodying our invention. Fig. 2 is a plan view of the saine. Fig. 3 is an end view of the conveyer-frame and motor with the hop er removed. Fig. 4 is a transverse sectiona view on the line 1 1 of Fig. 1 looking in the direction of the arrow. Fig. 5 is a si e elevation of another form of the apparatus. Fig. 6 is a plan View of the same.

. j 6()` .Y il Referring to the drawings, in'Fig. 11 the Y conveyer-frame A supports the idlers B and" 13 13 of Fig. 13.

C, over which the continuously -traveling convefer-belt D runs, suitable means being provi ed for driving the belt, as the motor E, connected to operate the tail-pulley F, over which the belt D passes. At the opposite end of the belt a suitable take-up may be provided, and, as shown, a brush G is utilized for keeping the belt clean. According toour invention the delivery end of the conveyer'is movable in all directions in a horizontalf-f I While various means may be provided for carrying out this object, according j plane.

to the form of apparatus shown in Fig. 1 the frame A is bodily movable horizontally about a suitable pivot, and it may also be tipped in a vertical plane. As shown, the turn-table H is provided with a track I, bearing u on the rollers J, journaled in suitable bearlngs upon the bed K. The turn-table H in'this instance carries the frame L ofthe hopper O, and a pivot-pin P is interposed between the turn-table and the bed K to center the table. The conveye-frame A is supported at its outer end upon a swiveled roller Q, which may run upon the ground, while a bearing is aorded for the other end of-tlie frame upon the rollers R, arranged upon the turn-table H.

According to the construction described it will be seen that the outer end of the frame- A, and with it the delivery end of the conveyer, may be swun in the horizontal plane through three hun red and 'sixty degrees, and it ma also be raised up and downin the vertical plane about the rollers R. Furthermore, the conveyer-frame may be moved in and out under the hopper the side channels S then rolling upon the rollers R, carried by the turn-table.

In Fig. 5 another form of apparatus is shown. In this instance the frame T for the hopper U is carried upon the conveyorframe A, which in turn is pivoted about the axis V upon the turn-table W. In this construction the turn-table is provided with the roll- Y View IOO ers X, running upon the track Y, and, as before, there is a pivot-pin Z for centering the table W. A swiveled roller a supports the outer portion of the frame A. According to this construction the conveyer can make a full swing of three hundred and sixty degrees in a horizontal plane,I and it can also be moved in a vertical plane around the axis V; but no provision is adorded for sliding it relatively to the table W, as in the construction previously described in connection with Fig. 1. In Fig. 5 the conveyer-belt D is driven from a-tail-drive by means of the tail-pulley b, and there is a snub-pulley c arranged at the upper side of the belt, as described and claimed in the copending application of Clarence Kemble Baldwin, Serial N o. 148,352, filed March 18, 1903.

The driving engine or motor may be placed upon the ledge or extending portion d of the frame A, and in order to equalize the weight of the engine and its parts upon the frame the engine-shaft e is extended by means of the coupling f, and the fly-wheel g is placed on the opposite side of the frame from the engine, thereby equalizing the Weight on the turn-table. Suitable operative connections are interposed between the engine-shaft and the tail-pulley--as shown, a chain 7L connectl in the sprockets 'i for driving the conveyer- In combination with the continuouslytraveling conveyer-belt we have shown some arrangements of shaking or reciprocating chutes for feeding the material to the belt, so constructed as to rapidly and uniformly feed the material and obviate all danger of damage to the belt by contact with the chute. I-Ieretofore feeder-chutes have been hung at both ends by rods or chains, with a drivingrod connected at either the back orfront end, according to circumstances. The result is .that the `feeder-chute has a tendency to swing in a horizontal plane unless guided by some suitable means, and this swinging is a great disadvantage when feeding a belt conveyer, owing to the liability of damaging the belt. There is also danger that the chains or rods carrying the front end of the chute will stretch and allow the chute to come into contact with the belt. According to our construction the front or delivering end of the chute j is carried on a pair of wheels or rollers 7c, running on a short section of track Z, so that the relative position between the end of the chute and the belt is substantially constant. We do not necessarily limit ourselves to rollers running upon a track, as other suitable means may be provided for keeping the relative position between the end of the chute and the belt substantially constant. The rear or receiving end of the chute j, as shown, is hung in this instance from the frame T by rods o, and provision is afforded for raising and lowering the suspended end of the chute j. The rods may be provided with adjustingholes p for adjusting the height of the chute.

Suitable devices are provided for imparting a reciprocating or shaking motion to the chute, as shown in this instance a disk crank g belng journaled upon the frame A and provided with a connecting-rod pivoted to the axle of the wheels c under the chute. The disk crank Q may be provided with apertures r for varyin the distance of the point of attachment o V the connecting-rod s from the center'of the disk crank, so that the length of the stroke may be varied. The disk crank g is connected to be driven by means of the sprockets t and chain u from the tail-pulley shaft. By varying the angle of the chute the amount of material discharged per hour may be altered at will. According to our construction the back or suspended end moves in the arc of a circle, while the front end moves in substantially a straight line, so that the material is drawn from the hopper durin .the forward portion of each stroke and t e chute drawn from underneath the material by the return stroke, thus allowing the material to fallA freely to the belt. As hereinbefore described, according to our construction the front end of the feeder-chute is not `permitted to swing in a horizontal plane, and, moreover, the angle of the chute may be adjusted While the same is operating, as hereinater to4 be described. The angle, of the chute and extent of the throw may be varied at will. In F' 9 a different' device -is shown for adjusting. t e angle of the chute, in this instance the back end of the chute being hung by the rods 'o and each rod being provided with a turnbuckle fw. At. the upper end of the buckles are sprocket-wheels connected by a chain y. At the other ends of the buckles are the hand-Wheels z, so that by turning one hand-wheel the turnbuckle will be operated and both rods lengthened or shortened to vary the an le of the chute.

In Fig. 12 a modified orm of a paratus is shown which is applicable to botih the constructions shown in Figs. 1 and 5. In Fig. 12 the outer end of the conveyer-frame is provided with a movable or hinged portion 1, so constructed that when the main portion A of the convey-ing ap aratus is elevated at an angle in a vertical p ane the hinged portion 1 may be adjusted to lie in a horizontal lane at a different angle from the main ortion of the frame. It is to be understoo that the hinged frame 1 may be attached to the outer end of either of the constructions shown in Figs. 1 and 5. In Fig. 12 the portion 1 is shown hinged to a frame A by way of illustration, in this instance the frame A' being provided with canvas decking 2, which iS utilized to keep the material from dropping onto the return-belt, and by the use ofcanvas also the weight is reduced. O'f course suit- ICO IIO

able materials other than canvas may be utilized for the same object. In the construction shown in Figs. 1 and 5 sheet-iron deckings are provided. Suitable provision is afforded for supporting the frame A in an in-l clined position, as desiredas shown, a portion of a chain 3, ring 4, and hook 5 being shown connected to a portion of the frame and the angle of the frame A having been determined as desired the remaining portion 1 of the frame may be arranged in prolongation thereof or inclined at an angle thereto by adjusting the bolt 6. The frame A is provided with the aperture 7, while the frame 1 is provided with the adjusting-holes 8. The frame 1 is pivoted to the frame A at the point 9, and the holes 8 are upon the arc of a circle struck with the pivot-pin 9 as a center.

One of the important advantages of a construction such as shown in Fig. 12 resides in the fact that material may be delivered from a low elevation to a high elevation in a horizontal plane. One instance of the usefulness of the apparatus described is found in those cases Where it is desired to deliver material from a dock to the deck of a vessel which stands at a considerably higher elevation than the dock, and many other instances may be found in which these or similar conditions are to be met.

In Figs. 13 and 15 it will also be seen that the fly-wheel 10 of the engine 11 has been removed and placed at the opposite side of the frame from the engine in order to equalize the weight. Another feature of the construction shown in these figures resides in the fact that the driving engine or motor 11 for operating the belt continuously instead of being placed at the tail end of the conveyer drives from the head end and is supported upon the hinged or jointed section 1 of the frame of the apparatus. As shown, the engine 11 is supported upon the frame or bracket 12 at one side of the frame 1. The fly-wheel 10 is supported on the other side of the frame 1, and suitable belt connections 13 operatively connect the engine-shaft 14 with the head-pulley 15 of the conveying-belt B.

Obviously some features of our invention may be used Without others, and our invention may be embodied in widely-varying forms.
