illthey are handled in connection with their utilization or storage. I

In such operations as the making of shoes, certain work-portions, of which the soles furnish an example, are coated with cement.

1.; Before these are used or'placed in books to be distributed to operators, they are exposed for a time to the air, so they shall not be unduly sticky. In this connection, a common practice isto deliver the articlesfrom the cementer to a long conveyer, which extends as far as possible through the factory, they being sufiiciently dried when they have reached the opposite extremity. This is ob- 2b viously wasteful of space, and factory buildings are often of such a character that the necessary extent of travel is difficult to obtain. It is an object of this invention to provide, in a simple manner,as long a path as is necessary through which the work-pieces may advance, this path lying within a relatively contracted area and also having comparatively small vertical dimensions. To thls end, I arrange a belt-conveyer in a coil w1th successive convolutions of the coil resting one upon another and along which articles are conveyed, and with this conveyer associate means for causing its travel. To apply this driving power, the belt, which is preferably endless, is extended from the coil in a loop,

and power means is associated with this .loop. The coated pieces may be delivered to one extremity of the coil and removed at the other extremity, passing between the successive convolutions or vertical layers, the number of these being sufiicient to give the desired length of travel. To allow access of the air to the drying articles, the belt, which is flat, is preferably foraminous, the particular form illustrated being reticulated, with the meshes formed by succesesive links. The coil is. shown as carried upon a support, which is r0- tatable to permit the free advance of the belt, its axis being preferably vertical, and there being a flange at the lower extremity of the support upon which the coil rests. The

of the coil, as a terminal convolution and that I adjacent to it, which means may consist of lnchned plates or walls extendingybetween said convolntions.

Additional power means may be associated with a separator, as between the last layer of the belt and the adjacent layer. This assists in advancing the belt, especially overcoming the frictional resistance of the separator. Means is provided for guiding the belt toward and from the coil at its extremities to form the loop. Over the guides the belt is preferably drawn at the lower end of the coil, and returned vertically to the upper extremity, so-it is led by gravity upon the top layer or upon the separating wall associated with said layer. 7 I

A specific embodiment of this invention appears in the accompanying drawings, in which Fig. 1 shows" my improved conveyer in perspective Fig. 2 is an enlarged detail in perspective of one'extremity ofthe lower separator and its more closely associated elements;

, Fig. 3 is a vertical section takentrahsverse- 1y of the axis of the roll .co-operating with the lower separator; v

Fig. 4 is. a perspective view illustrating the construction of the belt, and

Fig. 5 is a perspective View looking toward the edge of the lower separator, with the.

belt B, its inner edge contacting with the pe stantially fiat on the flange 16. The supporting surface of this belt gives comparatively small areas of contact with the objects which it carries,these being along narrow lines made up of sections 24: of different links, such lines being spaced from each other and inclined across the face of the conveyer. The belt B is endless and is led in a loop from the upper and lower extremities of the coil. Considering the outgoing end of the coil, it leaves its support upon the flange 16 and passes, preferably in a substantially horizontal direction, over a guide-roll 26 rotatable about a horizontal axis upon the end of the frame, then below this and the drum to a guide-roll 28 turning in the opposite extrem ity of the frame. From the roll 28, the belt rises to an abutment-roll 30, between this and a co-operating driving roll 32 preferably faced with some such yieldable material as rubber. The contact of this yieldablesurface with the irregular face of the belt produces a good driving engagement. The roll 32 receives power from a pulley 34 or the like and draws the belt from the coil, rotating the drum about its spindle, said belt being returned to the top of the coil over a roll 36, which is shown as adjustable in slotted standards 38 upon the top of the frame. The height chosen for the roll 36 is sufficient to causethe vertical run-of the belt to descend under the influence of gravity, and at the same time take up the portion between the driving rolls 80, 32 and the guide-roll 36.

Atthe points where there is a change of direction of travel of the belt from the coil to the loop and the reverse, there might interference with the advance of the work pieces being conveyed. The entrance of these pieces between the upper and succeeding layer might be, resisted, while their passage in leaving the coil between the tangential lower layer and that above it would tend to displace the pieces. These effects I prevent by the introduction of separating plates or walls between each outer convolution of the coil and thatadjacent to it. Beneath the incoming layeris placed a plate 40 mounted upon the frame and inclined downwardly from a point somew rat to the rear of the belt descending from the roll 36; until it is above tiie second turn of the coil. A vertical flange 42 upon the plate 40 retains the belt at this point against outward displacement. The plate here forms a tapered throat, into which the work-pieces readily enter when passing on the second layer beneath the first.

etween the outgoing run of the belt and the layer above it extends a plate 44 with a gnarl-flange 926 at its outer edge. This so separates the straight portion of the loop from the curved convolution'of the coil above that, during the change of direction of the articlesconveyed, they are in contact only with the former. 1 1

Assistance be given to the power-roll 32 in forwarding the belt by auxiliary driving means. This is of peculiar utility where the weight of the coil causes it to drag upon the plate a l. I therefore place at the inner end of this plate a yieldable-surfaced roll 48 journaled in the frame transversely of the belt, and the upper portion of which is just above the supporting surface of the plate 4 Rotation imparted to the roll, in the direction of the arrow in Fig. 3, through bevel-' 50, a vertical shaft 52, bevel-gearing rizontal shaft and belt-gearing 56, The roll 48 54-, a ho from the shaft of the roll 32;

holds the belt away'from the adjacent edge of it is sometimes found that the coil of belt tends to rise at its inner side under the influence of the all upon it, thus giving a downwardly and outwardly inclined surface, rather than the substantially flat surface desired. 'This may be prevented by applying pressure to the upper layer of the coil, as by idle roll 58rotatable about a spindle projecting from an arm 60 pivoted upon the frame. This roll is of sufiicient weight to hold the belt in place upon the support, but n ay rise as the work passes beneath it.

v In using this conveying and drying apparatus, the belt Bis caused to advance constantly through power applied at-the rolls 32 and 48. The coated'work-pieces such as soles S are delivered as from a cementing machine, coated sidesdown. to the upper layer of the belt at or near the point A. Y From this they are delivered to the throat beneath the l0, thus entering upon the second layer and so continuing, convolution by convolution, to the bottom, of the coil. of the limited areaof cont act of the belt-links at 24'.- with the under sides of the pieces, the

in reasonable limits of vertical height, it will be evident that the path through which the work travels may be as long as desired, with out increasing the area occupied by the apparatus, such area being very small. Air passes freely between the meshes of the belt, thus facilitating the drying operation, and this may be further hastened by delivering a cur rent of heated air upon the coil. On account of the relatively small space occupied by the conveyer, such a. delivery of air may be made more effective by enclosing theapparatus in a. housing.
