- Application filed December 16. 1910. Serial No. 597,610.

To all whomit may concern:

Be it known that I, \VILLIAM BARKER RUGoLEs, a citizen of the United States, residing at Bayonne. in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Portable Driers, of which the following is a full, clear. and exact description, such as will enable others skilled in the artto which it appertains to make and use thesame.

This invention relates to drier-s, and with respect to its more specific features. to portable driers of the kind involving a substantially horizontal rotating drum through which a heating medium is adapted to flow,

One of the objects of the invention is to provide a drier of the above type of such substantial construction that it may be readily and easily transferred from place to place without impairing its efliciency.

Another object of the invention is the provision of a drier of the above style with a liquid fuel heating system which not only efficiently dries the material, but is readily adapted to the necessities of transportation. Another object of the invention is the provision of a simple and efficient furnace, preferably of the oiLburning type. and one which is especially desirable in connection with a drier of a portable character.

Other objects will be in part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement, of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings wherein are illustrated some of the various possible embodiments of the invention. Figure 1 is a side elevation of the portable drier: Fig.

is a plan view; Fig. 3 is a front end elevation; Figs. & and 5 are detail views of the feeding buckets; Fig. 6 is an enlarged longitudinal sectional elevation of the dischargr end of the drier. Fig. 7 is a front elevation of the feed end of the drier.

The numeral 1 indicates a support or wagon body beneath which are suitably attached running wheels. The support may be of any suitable material and construction. but is preferably of a generally rurtangular shape. comprising metallic I-beams suitably spaced and braced to provide a substantial. framework to support the several devices composing the drier. The rear running wheels are so joined to the support as to be capable of steering the same. Mounted on cross-,pieces of the support are two series of bearing rollers 2. made of chilled iron.

These rollers are arranged in line across the support and suitably placed to accommodate the curvature of the drier d rum.

The drier comprises two concentrically arranged shells 3 and 4 of generally cylindrical shape. The outer shell 3 is provided cxteriorly with two heavy rolled steel tires 5 riveted thereto, which, when the drum is mounted on the support, rest-on the rollers 2, said rollers being so placed at either end of the support as to maintain the drum slightly inclined to the horizontal when the support is in normal level position. Thrust bearing rollers 5 are provided to prevent longitudinal movement of the drum. The shell 3 is also provided exteriorly with a gear 6 concentric therewith. meshing with a pinion 7 on a shaft having a bevel gear S engaging a bevel gear 9. rotatable on a cross shaft 10. carrying at one end a sprocket wheel 11, and at its other end. belt wheels l2 and 13.

The outer shell of the drier drum is made of steel plates. The inner shell or lluc lis also made of steel plates and is connected to the outer shell lrwcast iron straps ll, solidly riveted to both cylinders so as to hold the two shells rigidly together. lictween the center and each .end are sets of flexible links 2i. which allow for expansion and contraction due to changes in temperature. The drum is also provided with longi tudinally disposed vanes ll arrang d about its inner -wall to lift and stir up the material as it passes along.

The inner shell or flue -lis enlarged as at 14 near the header feed end of the drum and extends beyond the outer shell. passing through the stationary head or hood 1? and surroimding. but spaced from a combustion chamber or flue 16. in which combustion of fuel for heating takes place. The fuel burner will be described hereinafter. The chamber or flue 16 is cmicentrically and adjustably supported with respect to the cm larged portion ll of the flue by means of the straps 17 and it? and the ring 1 (see Fig. it) its end extending beyond the line l and lOO - chamber 16 tion 'of the length while the straps 18 are secured to the of the hood.

16 may be open its full diameter, butprefer-- -space between the chamber 16 I portion 11 in the ordinary operation of the and its position may I adjusted with respect to the flue l1. Asshown; the straps 17 are secured to a generally rectangular framework consist-ing of angle bars 20 and brace bars, cap. The outer end of the chamber therefore "be ably-a head is provided. having a central opening leading into said chamber.

The chamber orflue 16 is preferably lined with fire brick, and projects into the enlarged end 11 of the'fi'ue 1, and provides a concentric opening or space between the outer face of the one and the inner face of the other communicating with the atmosphere'and the flue 1 for the free entry of fresh air to the fine 1 at this point. It will be noted that the air "passing through the and enlarged device will be heated by the'walls of the and this heated air will enter a point remote from the burner. passes through the greater porofthe drum and opens directly thereinto at its rear end. By this construction it will be observed that'when a draft is established through the hood the products ofcombustion pass from thechamber 16. adjacent the front end of the drum, and are discharged to the rearthrough the flue 1,and back to the front end through the space between the flue 1 and the outer shell 3.

Thestationery hood 15 is of a generally cylindrical form closed at each end. The hood is supported by legs 25, which are attachedto'the body portion 1. and is further held in place by plates 26 attached to the cap 22 and to the angle bars 20. The rear end of the hood is provided with a central opening adapted to receive and form a collar around the drum. Thus between the eXten sion 11 and the peripherv of the hood '15 the flue at Theflue 1 an annular chamber is formed into which the drum opens.

' In the upper portion of the hood is an openingcommunicating with a pipe 27 leading to a stack or a rotary exhaust fan 28,

which in turn communicates with the atmosphere. The fan and piping rest on a framework composed of angle bars 20 and 29 and braces The shaft of the fan 15 1)1OV1C1QCl with a belt wheel 31 dri 'enfrom the wheel 13 on the shaft 10. The hood is-provided with doors 31 on opposite sides of the center to permit entry thereto and to the drum. The farther end .of the drum is provided with a door for a similar purpose.- The material to bedried is introduced into thedrum through an inclined spout 32 situated at the head ofthe ,drum between the shell 3 and the flue 11L The delivery end of the spout terminates above the center of the drum and the material falls upon a series of shovels or buckets to feed 01' guide the material well into the drum.

In the preferred form of feed device shown in Figs, 1 and 5, the, material is caught and deflected into the drumby a 011'- cular series of members,herein shown as flat plates or buckets 33. These plates are formed of integral pieces of steel and are preferably attached in any convenient manner to the inner periphery of the drum 3 and the outer periphery of the fine 11. The plates are preferably quadrilateral and have two parallel straight edges and two curved edges, the curved edges being adapted to conform respectively to the outer periphery of the flue 11"and the inner periphery ofthe drum'3. Each plate, as shown in this embodiment, lies in a plane perpendicular to the surface of the innerfiue and oblique to is axis and eachone is inclined inwardly downward, its pl theperiphery. On'acco'unt of the general structure and disposition of theplates, the material delivered upon them is urged well into the drum when the latter is rotated. Such buckets could also be used, of course, with structure maybe easily and cheaply made and on account of its simplicity and compositibn is very durable. 1

The material maybe fed to the spout in any approved way, but in order to make the drier automatic, a conveyer of suitable character is provided. In the present in stance, an endless conveyer or elevator 31 is removably supported at one end by the framework of angle bars 20.. The buckets of the conveyer deliver into the spout The upper shaft 35 of the conveyer turns in suitable bearings on the angle iron framework and 1s provlde'd w1th a bevel gear 36 meshing with'a similarfgear 37 attached to a shaft 38 suitablysupported; To the shaft ,88 is hired a sprocket wheel 39 and a sprocket chain connects the wheel 39 with the sprocket wheel 11 on the shaft 10.

The discharge end of the drum is provided with a central opening and around said opening on the inside of the end of the drum and oblique to the edge thereof are secured a pluralitv of flights or'plates10, Z-shapedpockets and as the pockets incline the material is discharged from their inner open ends.

The rear end of the drum is also provided with a central opening 11, and

within the mounted opposite the opening drum is a discharge plate 12 of conical formation I having a plurality; of radially disposed partitions 13. The apex of the'cone ane hence being oblique to a non-rotating 'drum. The bucket is aised above the openingas the drum rostates "and 1s dehvered from the pockets i0 upon the;curved surface the cone, which chamber 16. p braces extending from the frame 1 and carries a y ir supply system.) This system COI'HPFISGS afuel tank and an air-"pump 61 operated deflects it through theyopening. The partitions43 are intended toprevent any material falling back into the drum.

The heat used inthedrier is derived from thecombustion of liquid fuel, preferably some oil like fuel oil. The support 1 liquid fuel burner 59 and a fuel and abeltfronr the wheel 69 on the shaft 10. A pipe 62 extends fro nthe pump to the tank and serves to deliver air therein to force the fuel oil from thetank up through the pipe 63- to. the burner which is situated in juxta position to and adapted to deliver into the Pipe GQis held in place by pipe 63 is secured to the angle bars 201 Another pipe 16;") extends from pipe 62 to l the burner; and is adapted to supair to the burner. This pipe is likewise supported bythe bars 20. Allpipes are provided with regulating valves and the burner isfprovided with the customary needle valve.

Ignition of the mixture results in a large volume of highly heated products which pass. into the exteni Asdriers of the type herein described are of somewhat large proportions and consider ableweight, their practicability is added to byany reduction of their size, or the weight of parts, without sacrificing strength or capacityJf By employing an .oilburner of the kind, herein described an: efficient drier of comparativelysmall size and weight is produced, and onewhich isportable and easily manipulated, Suitable brake shoes (56 for the wheels areprovided. and maybe operated through the hand lever 67 and the rod 68. a a

The operation of thetdrier is as follows:

The drier is connectedby abelt on the pulley 12 to any suitable source of power.

Through the described gearingthe drum is rotated, the fan:is operated, and the pump set in motion to feed the oil and an to the burner Thccombustible mixture in the chamber 161s ignited. and the products of combustion passtherefrom into the fine 4,

From here the gases pass back to the head of the drum in contact with the material to bedried, thence into the hood, thence to the fan or into the stack, according to which is employed. The conveyor feeds the material into the spout, whence it passes into the drum by way of the buckets, the rotation of the drum continually turning the material over and over and dropping it onto the hot flue 4, whence it falls to the bottom of the drum, the inclination of the drum causing the material. to progress from end to end therein.
