SPECIFICATION forming part of Letters Patent No. 702,408, dated J' une 17, 1902. `Application led December 23, 1901. Serial No. 86,897. (No model.)

To all whmn t may concern.:` i

Be it known that I, JOHN H. COOK, a citizen of the United States, and a resident of New York city, in the county ofKings and State of New York, have invented certain new and useful Improvements in Conveyors, of which the following is a specification, taken in connection with the accompanying drawings, forming part of-the same.

This invention in the embodiment shown 1n the drawings relates to conveyers more particularly adapted to distribute material throughout a storage-building.

In the accompanying drawings, in which the same reference characters re`fer to similar parts in the various ligures, Figure l isa view in perspective showing my conveyor as set up in a building. Fig. 2 is a detailed perspective view of part of the conveyor, and

Figs. 3, 4, and 5 are detail views of thesame.`

The storage-building A is provided at one side of the same with the overhanging supporting-trusses A,which serve to support the upper end of the hoist B. This hoist is composed of a series of parallel sprocket-chains B', passing over the sprocket-wheels B2 at the lower end and over corresponding sprocketwheels B3 at the upper end of the hoist. The sprocket-wheels B3, which are supported by the trusses A', are rotated by suitable driving-gear B5. The series of carriers B4, mountyed upon the sprocket-chains B', are in this manner moved continuously and serve to transport packages of material (indicated in -larlyconnected to the sprocket-chains.

ried by the belt F'.

Ydeposit the bags in the upper end of the inclined trough F.

As is shown in detail in Fig. 5, the carriers are composed of a series of arms B4, pivoted to bars mounted transversely on the sprocket-chains B. These bars are pivoted to links B, which are simi- A series of inclined guides are mounted adjacent wheel B3, the outer guides Fs being suitably supported from the sprocket-shaft Or by any other desired means, while the inner guides F4 are not supported at their upper ends, but are made short enough to allow the bars upon the sprocket-chains to pass them. It will be seen that by these means the bags or other articles as they are carried up on the carriers B4`are thrown by these carriers upon the inclined guides and thereupon pass down upon theuchute F. along which they are car- This trough is mounted so thatit maysupply bags to the feeder-conveyer C, with which this trough is shown as cooperating, or with the feeder-conveyer on the other side of the building. The troughbelt F 'operates injthe trough and is driven by suitable driving-gear F2, connected with the hoist driving-gear, and in this manner the trough-belt servesV to feed the bags down the troughin a regular manner.

Instead ot' the particular construction of hoist here indicated any other desired hoisting means may be employed. V Near the middle of each one ofthe rooftrusses A2 are secured the longitudinal girders A3, which serve to support oneither side the feeder-conveyer C.

Referring to Fig. 3, it Willbe seen that the trolley-track A7 is supported in a rigid frame A, extending longitudinally of the girders A3 at the upper end of the same. This trolleytrack is of the D formation shown, and since the guide-grooves A9 at the lower part of the track are rounded the trolley and track are self-aliningand the track serves to guide the trolley-wheels C4, so as to preveut late1al displacement of these wheels. It desired, any other means of maintaining these trolleywheels in lateral alinement can be used. The

IOC

conveyor-slats C are rigidly secured to the brackets C2, and these brackets are fastened at their outer ends to the sprocket-chains C3, extending longitudinally of the conveyer. A trolley C5 is rigidly secured to every alternate bracket, as is indicated in Fig. 4, and the two trolley-wheels C4 are pivotally mounted on either side of each of these trolleys. The two brackets C2 which support a single slat are connected together by means of a spacingrod, which serves to keep the lower ends of these brackets at the proper distance apart. If desired, the slats may bel supported by any other desired means, and, indeed, any other form of conveying-surface may be supported from the trolleys. It is preferable, however, that part of the slats shall be rigidly supported and that the rest of the slats shall be supported in a yielding manner, so that they may assume a position below the rigidly-supported slats. The chains C3 pass over the large sprocket-wheels C7 at either end of the conveyer, and the driving-gear CS, which consists, preferably, of au electric motor with suitable reducing-gear, operates the sprocketwheel C7 to move the conveyer at the proper speed. It will be noted by reference to Figs. 2 and 3 that the facing A8 is secured adjacent the conveyer-slats and substantially on the same level with them, so as to give a supporting edge on either side of the slats.

The ejector or throw-off board D is secured in an inclined position upon the conveyer by clamps DS ot' any suitable construction, by

which the ends of the board are rigidly clamped upon the conveyer-girders. This board is formed with a series of inclined guides D', which extend along the face of the board and are arranged in the diagonal manner indicated in the drawings. A second set of vertically-inclined guides D2 are provided, if desired, of slightly less height than the first and interspersed with them. Instead of forming the throw-off board with the verticallyinclined guides indicated the throw-off board may be formed, if desired, with a facing-belt preferably vertically inclined in' the same manner and either positively actuated or allowed to move freely under the action of the bags engaging the board. A series of wheels might be employed on the board, if desired, to lessen the friction of the material against the board. This throw-off board, as

will be apparent, may be clamped in any desired position upon the conveyer and serves to engage the bags of material fed along the conveyer and to crowd these bags laterally from the conveyer upon the chute EG. The operation of this throw-off board may be readily understood by reference to Fig. 4. The bag or other equivalent package of material which is carried along upon the conveyer-slats E/ is shown resting partly upon adouble slat at the right of the figure, which is provided with a supporting-trolley C5, and thus is maintained at all times at the same height, since the trolley-wheels C4. are supported by the track. (lndicatedin dotted lines.) Thefront portion of the bag rests, however, upon the double slat, which is not provided with a supporting-trolley. The bracket upon which this slat rests is supported solely by the sprocketchain C3, and the weight of the bag causes considerable sag of the chain at this point, so that the front portion of the bag is supported in a lower position than the rear of the same. It will be seen that in this manner a considerable ledge is formed by the forward end of the rigidly-supported slat and that this engages the bag, so as to prevent to a very considerable extent the slipping of the bag back along the conveyer. The bag is fed along in this manner and engages the incilned throw-off board D, by which it is crowded laterally off the conveyer. The, verticallyinclined guides upon the throw-off board engage the forward edge ot' the bag and mate.- rially aid in this operation, since they tend to raise the forward end of the bag to some extent as the bag passes along the throw-off board. This renders it practically impossible for the bag to become wedged under the throwoff board, which would be undesirable. As the bag is crowded off the conveyer it is supported at the edge of the same by the facing AS, which prevents any injurious contact of the ends of the conveyer with the bag. Although in practice some slight slip of the bag occurs along the conveyer after the bag engages the throw-off board, this has not been found aserious objection. The forward edge of the rigidly-supported slats finally engages the bag and prevents the backward slip of the bag, and thus crowds the bag off. In some cases the bag is not entirely thrown off the conveyer, but hangs suspended from the facing. In such a case the succeeding bag as it engages the throw-off board serves to entirely disengage the first bag and throw it uponthe chute.

The trolley-tracks A4, preferably similar in construction to the trolley-tracks A7 just described, are rigidly secured to the roof-trusses A2. These tracks, in connection with similar tracks A5, secured to the outer walls of the building, serve to support the trolleys E, secured at either end of the girders E2 of the transverse distributer-conveyers E. In this manner the distributers are bodily movable longitudinally ofthe building, so that they may cooperate with the feeder at any desired point, the throw-oft' board D upon the feeder being adjusted to correspond. The distributers E are of substantially the same construction as the feeder, which has been described in detail, and they are provided with throwoff boards EL, which have a similar operation to crowd the bags oif the conveyer and upon the chute These throw-off boards may be adj usted at various points along the distributers, so as to crowd the bags off at any desired piace. The distributer-conveyers are operated by the driving-gear E3. By this means the bags of material may be distributed as desired within the building, since the IOO IIO

distributers may be moved to any desired point and would operate to discharge the bags upon the chutes E5, which may be placed at any desired point along the distributers. In this way the whole building maybe lled with bags of material, and since the conveyer mechanism occupies but little of the storageroom below the roof-trusses very little of the valuable storage-room of the building is unavailable.

Numerous changes may be made in the Vconstruction of this conveyer without departing from the spirit of my invention.

Furthermore, parts of this invention may be employed without using all of the same, and parts of this invention may also be employed in connection with other conveying means. I do not, therefore, wish to be limited to the disclosure which I have made in this case; but what I wish to secure by Letters Patent is set forth in the appended claims.
