- My invention relatesto. the class of machines employed more particularly for removing moisture from metallicarticles of various sorts that have been wet during the process of manufacture or in finishing, and
an object of my invention, among others, is
is the provision of a machine of this'class that shall be articularly efiicient in operatlon and that s allrapidly efiect its purpose.
One form of machine embodying myinvention and in the construction and use of which the objects herein set out, as well as others, maybe attained, is illustrated in the accompanying drawings, in which-' section throu h a machine embodying my invention, an on a plane denoted by the dotted line 1-1 of Figure 2;
Figure 2 is an end view lookingat the machine from the left as seen in Figure 1.
' Figure 3 is a view in cross-section of the piper portion on a plane denoted by the dotline 3-3 of Figure 1.
Fi ure 4 is a similar view on a plane denote by the dotted line 4-,4 of Figure 1.
Figure 5 is another similar view on a plane denoted by the dotted line 5-5'of Figure 1.
Figure 6 is still another similar view on a plane denoted by the dotted line 6.-6 of Fifilre 1, with parts. broken away.
the accompanying drawings the numeral 6 denotes a case that may be of any desired shape and composed of any suitable material, sa1d case bein enclosed except for 5 an inlet opening provi ed with a hop r 7 and an outlet openin 8 at-its front en the coated at one side of the center of the end of the casea'nd the outlet openin at the center thereof, and as shown-in i 2 of the drawin A sup out at each end of the case, said shaft be mounted in bearings in standards 10, 11, an having means, as a drivm pulley 12, secured to one end thereof and a aptedto receive a belt connected with any suitable source ofpower. A supporting late 13 is secured to the shaft. at the back 0 and within the case 6, and a supportin collar 14 is secured to i said sha'ft near the out end of the case. As a means for receiving the articles to be dried, for moving them from end to end of:
the case, and fordischarging them at the Figure 1 is a view in central lengthwise terminates prefera front end of the case ,1 provide threedrums that are secured to rotate with the-shaft 9 5 The outer drum 15 is preferably. cylindrical as to the greater partof its length, being .closedfat its back end, and such end being secured to the plate 13. The front end of this outer drum is provided with a ta ered flange 17 within which the inner end 0 the hopper 7 is located,-for the delivery of articles into saidaouter drum. This drum is supported at its'front end on supportin rods 18 secured to and projecting outwa y from the collar 14. A feed worm 19 secured to the inner surface of the outer drum is arra d to cause movement of articles and material from the front to the back end of the drum, and as shown in Fig. 1. I I The intermediate drum 20 is preferably tapered from a larger diameter at its front end to a smaller diameter at its back end and is of a size to provide a suitable space between its outer surface and the inner surface of the drum 15 for the travel of articles and material between said drums. This'intermediate drum is 0 en at its front end that bly back'of the ta red. flange 17, andas shown in Fig. 1 of the rawin The backend of this intermediate drum is closed byithe front wall of a trans ferrer 21 and sa1d drum is supported as by means of short rods' 22 at, its out and rear ends, said rods being secured to and projectin from-an inner drum to be hereinafter descrid."' '5 The transferrer occupies a space between the rear end of the intermediate drum,20 and the end'wall 16 of the outer drum and transfer the articles and material delivered (fa; thereto' fromthe outer drum. Thistransporting shaft .9 exten s through and its inner end terminating at an opening 23 into areceivin chamber. 24 comprising the back end of t e inner drum hereinbefore referred to. This chamber 24 is preferably of c lindrical form, extending from the-end wal 16 ofthe outer drum to a point within the'rear end of the intermediate drum, the wall of this chamber, as well as those of the outer and intermediate drums, being preferably imperforate. The wall of the central 10s portion 25 of the inner drum 1s perforated back end to a larger diameter at its front '-end, and the outer or discharge portion 26 of this inner drum extends from the central portion 25 of the inner drum out through the front wall 27 of thecase 6, and as' shown in Fig. 1 of the drawings. The front end of this lnner drum is sup orted by the rods 18, and the back end of said drum is supported against the inner surface of the end 16. of the outer drum 15. The outer portion 26 of the inner drum, is tapered prefer ably to conform to the taper of the central portion 25 thereof, and the wall of this outer portion is imperforate The chamber 24 is provided with a feed device wall to direct movement of articles and material from the chamber 24 to the central portion 25 of the inner drum, and the latter 1s provided with arshelf or shelves 29' extending longitudinally thereof and acting to carry the. articles and material, as sawdust, upwardly within the drum'and then cause them to fallto the bottom of said central portion of the inner drum.
v Feeders 30 in'the form of comparatively short strips are disposed in an oblique direction on the inner wall of the tapered flange 17 and in a manner to direct travel of articles into the outer drum. Any suitable means, as steam pipes 31, ma r be employed for supplying heat within t e" interior of the case 6 The 0 eration of my improved machine is as fol ows: y A A drying substance or material, as sawdust, is placed within the outer drum 15,, and the articles to be dried are introduced through the hopper 7 from which the fall within the flange 17. The several ruins, being rotated and heat bein supplied'within the case, the articles toget er with the material and sawdust is caused, by the feed worm 19, to travel 'to the back end of the outer drum where they are scooped up by the scoop-transferrer 21. Therotation' ,of this outer drum causes the articles to travel toward the center of said scoop and to be delivered through the opening 23,into the receivin chamber 24. From this chamber the fee device 28 causes'the articles and material to travel into the central portion 25 of the inner drum and the rotation of the latter causes said articles and material to be carried toward the front end. of the lnner drum. The sawdust or other drying material passes through the meshes of the inner drum into the interior of the intermediate drum, the articles being thus separated from such dryin material, and said articles passing out at t e end of the outer portion 26 of the inner drum. The material, d
owing to the rotation of the intermediate 28 of spiral form secured to its inner.
and is delivered out of the end thereof into the interior of the outer drum in condition for a repetition of the operation.
' In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have-it understood that the apparatus shown is only) illustrative and that the invention may e carried out by other means and applied to uses other than those above set out.
I'claim- 1. YA drying apparatus including a pinrality of concentrically arranged drums lo- 'receive said articles and drying material, an
intermediate drum to receive said material screened by the inner drum, means for transferring said articles and material from the outer to the inner drum, and means for rotating said drums.
3. A drying apparatus including an outer drum to receive and convey articles and drying material, an inner perforated drum, a spirally formed transferrer for delivering articles and material from the outer to the inner drum, and means for rotating said drumd a '1 a 4. rying ap' aratus inc u in an outer drum to receivt add convey article and drying material, an inner perforated drum, a sp1rally"formed' transferrer for delivering articles and material from the outer to the inner drum, an intermediate drum to receive material screened by the inner drum, and. means for rotating said drums.
