EDWARD S. MOWRY, OF MIDDLETOWN, CONNECTICUT, ASSIGNOR TO *WILCOX, CBITTENDEN-I' AND COMPANY, OF MIDDLETOWN, CONNECTICUT, A CORPORATION OF CONNECTICUT. I I v AIPFARAT'US non. cooLINe AND FINISHING- METAL-COATED. ARTICLE-S.

To all 'whomt't may concern: I r

' Be it known that I, Enwsnn S. MowaY, a citizen of the United States, residing at Middletown, in the county .of'Middlese x and State of Connecticut, have invented certain newand useful Improvements, in

coated articles, and refers more particularly to a device that receives metal articles after they have been coated with zinc, tin, or other similar substance for cooling and removing the excess metal therefromrand it is the object of my invention, among other things, to construct a deviceof this character, of the fewest possible parts, so designed as. to be economically constructed and readilyv assembled, that will effectually remove every particle of excess :mea1,-wm cool the articles as soon as possible after they have been placed in the machine, and will produce a more satisfactory product than is possible under present methods.

To these, and other ends, my invention consists in A the apparatus for cooling and finishing metal coated articles, having certain details of construction and combinations'of parts as will'be hereinafter described and moreparticularly pointed out inthe claims.

. Referring to the drawings, in which like numeralsofv reference designate like parts in the several figures; Figure 1 is a side elevation of my improved apparatus complete; Fig. 2 is an enlarged fragmentary sectional elevation of the separator and adjacent mechanism Fig. is an enlarged sectional view of the, open iend of one ofthe tumbling barrels.

In the practice of my invention I provide a separator which is preferably constructed with a plurality ef concentric sections '1 secured one above the other with the lower section fastened to a trough 3; Each of these sections terminates at its bottom end in an inwardly' flaring shell 21 A shaft 4 is rotatable within said separator and journaled within the cover 7 and bushing 11 in thehubof the stand 8 fixed to said cover, a ball I bearing1device9 taking the'weight of said' shaft and reducing the fi'iction. rotated by a belt- 'I3i driven by any-convenient means and passing over pulley 12-and idler pulleys 14 that are mounted on a bracket: 15 fixed to the cap 7 and stand 8. Fixed on said shaft are the conic'al disks-5, ,5 and 5 having beater rihs'mwin s fi-up'onupper surfaces.

Patented July 1 ,1907. i

Within the separator, below the cap 7, is a perforat d pipe 16 that is connected with a water supply by in inlet pipe 17 having, a valve'18 conveniently fixed 5'5" therein. Fixedto the cap 7, and projecting laterally therefrom, is a casing 18, within which shafts 19 and 2(). are journaled. Each of said shafts has a sprocket wheel I 21 thereon which engages and actuates an endless car-1 rier 22 of any preferred form or type which movesfin v.

inner end substantially a horizontal plane with the thereof over an aperture24' in the 'cap 7.

Rotatably connected with the trough 3 are theshafts' I. 25 and 26, to which are fixed sprocket wheels 27 whichf engage and actuate a substantially horizontal carrier 28 that moves through the trough 3; and beneath the 1 separator. On the shaft 26 is a pulley 29 that-is con f nected by a belt 30 with a pully 23 fixed. on the shaft. 20. Attached to the trough 3 adjacent to the shaft '25- 1 is a chute 31 which is preferably made of two sections 7'0 with an opening 32 therebetween. Conveniently 1o- T cated adjacent to the end of chute 31 is an elevater33.

having a plurality of buckets :34 thereon. This elee vator may be actuated by any convenient means, those herein shownconsisting of a sprocket wheel 35 fixed upon a shaft 36 which is driven by a belt 37 and an idler sprocket wheel 42 which supports the. upper D end ofsaid elevator. A belt 38 connects the'pulley' upon shaft 36 with a pulley on shaft 39 and rotates said shaft which is connected by a belt 40 with the pulley 41 on shaft 26. q l

The tumbling barrels-are herein designated 43 and are preferably of that type which'are open at one end" 1 and mounted so as to be moved to any of its positions. In the drawings 1', have shown fourof 35 these barrels but a greater or less number may be used e equally as well within my invention. The mechan ism for actuating .these floar'rels does not 'constituteaT ndtherefore I shall'not'i'describe it in detail, it being sulficient, however, to state x that the barrels are fixed upon a shaft 44 and rotated I from a shaft 45 having a pini n 46 thereon which meshes into a gear 47 connected with said bm'lfthe; shafts 45 being driven from shafts 4s and 52 bybelts: 1 49 engaging the pulleys 50. The shaft 52 isrotatedf 5 by a belt. 53 and the shaftsAB and 52 are operatix ely: connected with each other by the belt51. i I Above the barrels 43 is a plate 54 which is held-int. fixed polsition by suitable braces .55 and rotatable therein is a turn head 56 below which a distributing 100. chute 58, preferably having four separate compart i 3' ments therein corresponding in number to the turn bling barrels, is fixedby the bra ckets 57. I v A chute 59 is held by a bracket 60, or other rator onto said carrier with the coated articles.

means, with one end thereof adjacent to the upper end of the elevator 33, and the other end substantially coaxial with the turn head 56.

In operation, the articles, after being immersed in a molten mass of zinc, or other similar coating material, are dropped onto the continually moving carrier 22 which carries and drops them through the opening 24 into the separator and onto the disk 5. As they strike the disk they are either thrown outwardly by centrifugal force or by the action of the beaters or wings 6 to the wall of the separator, whence they drop downwardly and are again moved inwardly toward the center of the separator by the conical shell 2 and drop onto the disk 5? and the above operations are continued until the articles drop out of the separator onto the carrier 28. As the water passes down through the separator it is moved toward and away from the center of the separator by the disks 5, 5 and 5 and conical shells 2. The operations just described cool the articles, separate them from each other, and remove the excess material therefrom which drops through said sepa- A continuous stream of water is passing through said separator from the perforated pipe 16.for cooling the articles passing therethrough. The carrier 28 drops the articles onto the chute 31 which conducts them into the buckets 34. As the carrier 28 moves through the water in trough 3 the excess material adheres thereto and is not dropped onto the chute 31 but continues around with the carrier 28 and is washed therefrom, being thus deposited in the bottom of the trough where it is afterward removed. The articles are thus delivered into the buckets 34- substantially free from all excess material.

Ohute 31 is preferably made in two'parts, as shown, so that if any water is dropped thereon from the carrier 28 it will escape through the opening 32, while the coated articles will be deposited in the buckets. This type of chute prevents either water or excess material being delivered into the buckets, and materially aids in the manufacture of a superior product. From the elevator the articles are delivered into the chute 59 and thence into the turn head 56 ,which is manually adjusted to deliver the articles into any one of the four buckets in the distributing chute 58, from which they are delivered into one of the four tumbling barrels 43. The tumblingprocess knocks off the fine dust particles from the coated articles, as well as reduces them to an absolutely cooled ,state. Into each of the barrels is delivered a blast of air to drive out the accumulating dust particles which would otherwise prevent the coated articles from acquiring a high polish or finish. This blast of air is derived from a convenient source through a pipe 61 and thence through its branches 62 into each of said barrels. I prefer that the blast of air should be driven into said barrel and drive the dust particles therefrom, but they may, however, be drawn .out of said barrels and through the pipe 62 by a suction blast, if desired, and within my invention. After the articles have been in the tumbling barrel a suiiicient have provided means whereby during this operation any dust particles remaining in the barrel may be collected. Said. mechanism comprises a screen 63 secured to the open end of the barrel and projecting in front thereof. t I

,By the use-of a plurality of barrels and the turn head 56, each of the barrels may be operated on different classes of articles at the same time, and each of said barrels may be rotatedduring varying periods, it being practical to operate at the same time one of said barrels with screws, another with washers, still a third with a different character of articles, and so on without having to disarrange' the parts of the machine, or cause confusion, or accidental mixing of the different kinds of. articles. scribed the articles are relieved of every particle of excess material and are cooled as soon as possible after being coated, and when completed have a high polish or finish that makes them far superior to any product heretofore possible. 7

There are minor changes and alterations that can be made within my invention, aside from those herein suggested, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of myinvention.
