This invention relates in general to trans port mechanisms and more particularly has reference to a combination elevator conveyor.

Previous to this time there has not been provided any mechanism adapted to transport material from various points or from one elevation to another where the points of loading and the points of discharge are continuously changing in their relation to each to other.

An object of this invention is to provide a combination elevator and conveyer adapted to transport material from various points.

Another object of this invention is to provide a combination elevator and conveyer adapted to transport material from one elevation to another.

A further object of this invention is to provide a combination elevator and conveyer 2e adapted to transport material from various points, or from one elevation to another where the pointsof loading and the points of discharge are continuously changing in their relation to each other.

This invention consists in general of the provision of a transport device comprising a series of interchangeable units which may be combined to form various combinations of conveyors and elevators of any desired length.

With these and other objects in View which may be incident to my improvements, the invention consists in the parts and combina tions to be hereinafter set forth and claimed, withthe understandingthat the several necessary elements comprising my invention may be varied in construction, proportions and arrangement, without departing from the spirit and scope of the appended claims.

In order to make my invention more clear- 1y understood, I have shown in the accompanying drawings means for carrying the same into practical effect, without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation, have been made the subject of illustration.

In the drawings:

Figure 1 is a top plan view of the combi- 50 nation conveyor and elevator;

Fig. 2 is a side'elevational view of the combination conveyor and elevator functioning as an elevator;

Fig. 3 is aside elevational view of the combination conveyor and elevator functioning as a conveyor;

Figure 5 is an elevational view showing one end of conveyer section from the inside.

Figure 6 is an elevational view showing an adjacent end of conveyer section.

Fig. 7 is a sectional view taken on line 5-5 of Figure 4;

Fig. 8 is a front view section.

Referring by numerals to the drawings, wherein like symbols of reference refer to similar elements throughout and more particularly to Figure 1, the combination elevator and conveyor comprises a driving or discharging-section 1, a power section 2, a return section 8, and a body or filler section 4:.

The various sections comprising the combination elevator and conveyor are joined by a connection 5, illustrated in greater detail in Figures 4, 5 and 6 to behereinafter more fully described. The sides of the sections forming the conveyor frame are made up of oppositely disposed aligned channel irons 6 and 7 as shown in Figure 7. A plate 11 is centrally fixed to the inner surfaces of the channel irons 6 and 7 and fastened by angle irons 13 and 1 1 or by any other suitable means.

The ends of a shaft 15 are journaled in the frame on the end of the discharging section 1, as shown in Figure 8, and held therein by collars 16 and 17. A sprocket wheel 18 is key-ed to the end of the shaft projecting through the collar 16. There are also keyed on the shaft, sprocket wheels 19 and 21.

The ends of a shaft 22 are journaled in the end of the frame on the return section 8, as shown in Figure 1, and held by collars 23 and 24. There are also mounted on the shaft, sprocket wheels 25 and 26 in alignment with the sprocket wheels 19 and 21 keyed on the shaft 15.

05 of the discharge The power section 2 is mounted on a base 27 together with a motor 28. The motor 28 may be of any desired type deemed most suitable for the particular requirements and may be located at any point desired as it is manifest that a particular mounting of the source of power is in no wise a necessary feature of this invention.

The motor 28 is provided with a drive shaft 29 having keyed thereon a sprocket wheel 31. Mounted parallel to the drive shaft 29 of the motor is a shaft 32 supported by standards 33 mounted on the base 27. A sprocket wheel 34 is keyed on one end of the shaft 32 and another sprocket 35 is keyed on the other end, as shown in Figure 1.

The adjacent sections of the mechanism are joined by a connection 5, better shown in Figure 4 wherein the longitudinal sections through the open joint shown in F igures 5 and 6 show the details of the connection.

A splice plate 36 formed as a channel iron is riveted to the section 4 or secured by any other suitable means through apertures 32. The other end of the splice plate 36 is provided with apertures adapted to coincide with slotted apertures 39 bored in the end of the adjacent section 1, and secured thereto by bolts 41. The slotted form of the apertures 39 permits longitudinal adjustment of the sections.

Plates 42 are fixed to the top and bottom of the channel irons forming the frame on one end of each section to be joined and the adjacent section is slipped in between the plates. A plurality of blocks 43 are mounted on each section between the opposite ends of the plates 42 and fixed therein by bolts 44.

The connection is tightened after two adjacent sections have been properly drawn in position by takeup bolts 45 having heads 46 and nuts 47 extending through the blocks 43.

The plates 11 of the adjacent sections are beveled at their ends so that, when two sections are drawn together by the bolts 45 and fixed in place by the bolts 41, smooth running surface will be presented. A supplementary plate 48 is fastened beneath the beveled connections of the plate 11 to prevent leakage at these points.

Flanges 51 are mounted on the top of the frame to prevent spillage of material during operation. At the point of juncture of adjacent sections a supplementary flange 52, having an indented bottom portion, is insorted to clear the top plate 42 forming the connection 5 and engage the 'iange on the adjacent section. T he flanges may be dispensed with if so desired.

A flexible transmiss on mechanism 53, such as a steel chain, comprPsin nks and ers 55, is adapted to or e the "'1 sprockets 19 and 21 keye on ti on the forward section 1, and the s 1a sprockets 25 and 26 keyed on the shaft 22 on the return section 3. Transverse cross flights 56, having end portions 57, are mounted on the chain 53, adapted to slide on the plate 11. The cross flights 56 are suitably spaced to afford the greatest utility for the particular material being conveyed.

A suitable flexible transmission mechanism such as a chain 58 is adapted to cooperate with the sprocket wheel 31 keyed on the shaft 29 on the prime mover 2S, and the sprocket wheel 34 keyed on the shaft 32 on the driving section 2, as shown in Figure 2. A like chain 59 is adapted to cooperate with the sprocket wheel 35 keyed on the opposite end of the shaft 32 and the sprocket wheel 18 keyed on the shaft 15 in the end of the frame on the forward portion 1.

The prime mover 28, through this series of sprockets and chains, is adapted to operate the head shaft 15 and the driving sprockets 19 and 21 keyed on the shaft, which in turn operate the chain belts 53 rotating on the sprockets 25 and 26 keyed on the shaft 22. thus operating the cross flights 56 and affording forward or backward carriage of any material deposited on the plate 11.

The chains are adapted to be detachable or separable at suitable points so that they may be lengthened or shortened to accommodate the sections 1, 2 and 3 and the total of body sections 4 employed to make up a complete unit. The chain 59 is also separable and extensible or retractable so that it may be adjusted to suit any desired distance between the sprockets 18 and according to the number of body sections 4 used.

The operation of this invention may be readily understood hay ing reference to F igures 2 and 3. The form of the mechanism is dependent upon the position of the body or filler sections 4 with respect to the driving and discharge sections 1 and 2. Vhen the section 4 is inserted between the sections 1 and 2 the assembled unit is adapted to function as an elevator, as shown in Figure 2. to elevate material to a car 61 or any other receptacle, or if it is desired that the mechanism serve for longitudinal transport, the sections 4 are inserted between the power section 2 and the return section 3, and assembled in this form functions primarily as a conveyer with only a slight elevation at the end where the material transported may be discharged into a chute 62 or any suitable conveyer.

It is apparent that the assembled unit may be extended by inserting additional sections 4 up to the limit of the power of the prime mover 28 and the resistance of the chains 53 forming the conveying or elevating drive.

There is accomplished by this invention a combination elevator and conveyer having a series of separable interchangeable units adapted to be combined to form various combinations of conveyers and elevators to afiord eficient transport for materials where the point of loading and the point of discharging are continuously changing in their relation to each other.

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth, by way of illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing from the spirit of the invention, or exceeding the scope of the appended claims.
