DRYING-OUT BARREL.

vSpecification of Letters Patent.

Patented April 28, 1908.

To all whom it may concern:

Re it known that I', CHARLES L. WARNER, a citizen of the United States, residing at Watertown, in the county of Litchfield and- State of Connecticut, have invented certain new and useful Improvements in Drying- Out Barrels, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to new and useful improvements in drying-out barrels, and has for its object, among other things, to provide a device of this character having means for the admission of live steam therein and means whereby' the exhaust and condensed steam may be automatically taken therefrom. a

To these, and other ends, my invention consists in the drying-out barrel having certain details of construction and combination of parts as will be hereinafter described and more particularly pointed out in the claims;

Referring to the drawings, in which like numerals of reference designate like parts in the several gures; Figure 1 is a side elevation of my improved drying-out barrel, partly in section; Fig. 2 is an elevation of the closed end of the barrel, the sectional portion being upon line A-B of Fig. 1; Fig. 3 is a plan view of the shaft carriage with the steam boxes and barrel shaft partly in section; and Fig. 4 is a transverse sectional view of one of the steamV boxes upon line C-D of Fig. 3.

The device herein described, while not limited to such use, is more es ecially designed to be used for drying sma l metal articles after they are taken out of a wet tumbling solution, an acid dip, or a treatment of simi ar character. Y

In the practice of my invention I provide a barrel preferably in the form of the frustum of a cone, .and constructed with an outer shell 1 and an inner shell 2 secured together so as to leave an open space therebetween which is closed at the front end. yThe inner shell is provided with a head 3 and the outer p shell with a head 4, said last mentioned head having a hub 5 in the center-and an inclosed passage 6 extending radially from said hub and opening into an enlarged packet 7. Through the head 4 and opening into the pocket 7 is the opening or ort 8. The barrel is fixed on the end of a s aft 9which is rotatable in a carriage 10 that 'is movablyp mounted at its front end by the pintles 12 to the brackets 1 1 that are secured to the stand ards 30.

A rotary movement is imparted to the barrel from apulley 13 having a pinion 14 connected therewith which meshes into and drives a gear l15 secured to the head 4. Extendinglengthwise within the shaft 9 are the passages 16 and 17, the passage 16 opening through the end of the shaft7 as shown 1n Fig. 1, and having a passage 18 extending radlally therefrom through to the outside of said shaft. The passage 17 is closed at both ends but connected by a passage 19 with the outside of said shaft near its inner end and with a passage 20 to the outside of said shaft near the outer end. Surrounding said shaft are the steam boxes 21 and 22, each of said boxes being provided with the interior chambers 23 and 24 and held against rotary movement by the engagement of the screws 25 with the underside of the carriage 10 and against endwise movement by the engagement of said screws with the lugs 26 integral with said carriage. These steam boxes are held in a position wherein the passage 18 opens into the chamber 23 during all of its rotation, and the hole 2() into the chamber 24. Leakage from these boxes is prevented by the packing glands 27 which are connected with and adjustable therein in a well known manner. Threaded into said steam boxes are the pipes 28 and 29. A The carriage 10 is shifted upon eol its pivot mounting so as to bring the axis of i the shaft 9 in any intermediate position between the broken lines D-F and G-H of l, by means of the crank 31, which rotates a shaft 32 carrying a ratchet disk 33 and a pinion 34, a shaft 36 having a gear 35 thereon Which meshes into the inion 34, and a pinion 37 that meshes into t e teeth of a rack 38 which is connected with the carriage 10 by a pintle 39 and lying upon a rotatably adjustable support 40, and a pawl 41 which enchamber between the heads-3 and 4 andthe outer and inner shells 1 and 2, where it heats said barrel to the desired temperature. rIhe exhaust steam and Water condensed therefrom escapes from said chamber through the opening or port 8 into the pocket 7 thence through passage 6, passages 19, 1.7 and 2O to the chamber 24 in the steam box 22, and esca es therefrom through the pi e 29.

Ieretofore in drying out barre s it has been impracticable to automatically remove the condensed steam therefrom except by manual means and then only by stopping the rotation of the barrel. In my device these, and many other objections, are overcome, as the exhaust steam will automatically escape from the barrel through the port S, and the Water formed in said barrel also passes through said port, when, by the rotation of said barrel, the port is in its down position, and as the barrel continues its rotation the Water that has passed into the pocket 7 escapes by gravity through the passage 6 and is ejected through the pipe 29. Even while the barrel is stationary and the port S in its down position, the pressure of the live steam Will be 'sufficient to drive the exhaust steam and water out of the barrel through said port. I

Experience has demonstrated that the means herein described permits the barrel to be maintained at a high state' of temperature by the continual assage of live steam therethrough and all o: the water is ejected therefrom, the pocket 7 acting as a bucket to pick up the Water at each revolution of the barrel.

There are minor changes and alterations that can be made Within my invention, and I wouldl 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 my invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

l. In a device of the character described, the combination with a rotary jacketed barrel with a chamber between the walls thereof; of a shaft rotating with said barrel and provided With longitudinal passages therein lying side by side' and substantially parallel With each other; means for admitting steam to said chamber through one of said passages; and means for removing the exhaust steam and Water from said chamber through a second passage in said shaft.
