FLUE-RATTLER.

SPECIFICATION forming part of LettersPatent No. 779,468, dated January 10, 1905.

Application filed April 29, 1904. Serial No- 205,481.

To all whom it nuty concern.-

Be it known that I, RICHARD M. CROSBY, a citizen of the United States, residing at Oelwein, in the county of Fayette and State of 5 Iowa,have invented certain new and useful Improvements in Flue-Rattlers, of which the following is a specification.

My invention relates to that class of fluerattlers comprising a tank and a plurality of 10 chains, cables, or similar flexible elements movably mounted and extending into such tank for supporting and moving'or rattling the boiler-fines to be operated upon and provided with means for operating such flexible elements or forming a connection with a suitable source of power.

The principal object of my invention is to provide a simple, economical, and eflicient.

boiler-flue rattler.

A further object of theinvention is to provide in a boiler-flue rattler a tank adapted to contain a suitable fluid and the lines to be operated upon, chains, cables, or similar flexible elements for supporting and operating upon the fines while immersed in the liquid, and suitable mechanism arranged outside of the tank for operating such flexible elements, whereby the immersed flues may be rattled and cleaned and the operating mechanisms kept outside of and substantially free from the liquid in which the flues are immersed.

Other and further objects of the invention will appear from an examination of the drawings and the following description and claims.

The invention consists in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of an apparatus constructed in ac- 4 cordance with my improvements; Fig. 2, a longitudinal sectional elevation taken on line 2 of Fig. 1 looking in the direction of the arrow, and Fig. 3 a transverse sectional elevation taken on line 3 of Fig. 1 looking in the direction of the arrow.

In constructing a boiler-flue rattler in accordance with my improvements I provide a tank (0, having side walls 6 and 0, a preferably U-shaped bottom portion (Z, and end walls a and f, all forming a tank substantially U- shaped in cross-section and of suflicient length to contain the boiler-flues to be operated upon. I prefer to mount this tank in a suitable supporting-frame, comprising side frames 9 and it, end frames 2 and j, and supporting-saddles or center brackets in, the tank being firmly mounted upon the latter and inside of the framework. I prefer to make the supporting-frame as well as the tank water-tight. The supporting-brackets A, upon which the tank is mounted, are arranged at intervals along the center of the frame, so as to add to the rigidity and strength of the tank. A plurality of chains, cables, or similar flexible elements for supporting and operating the tubes or flues to be treated are arranged at the necessary intervals along the tank, so as to encircle it, each of such flexible elements being mounted upon a set of pulleys m, a, 0, and p, the pulleys m being mounted upon and keyed to a suitable driving-shaft Z, which extends longitudinally along preferably one of the upper edges of the tank and is rotatably mounted in suitable brackets (1 on the supporting-frame. The pulleys n are mounted over the opposite edge of the tank, where they are supported by a set of brackets r on the frame, being preferably keyed upon a rotatable shaft ,5, so that they will rotate together. The pulleys 0 are mounted in brackets t alongthe loweredge of the tank, being preferably keyed upon a rotatable shaft u, and the pulleys p are mounted upon similar brackets '0 along the opposite lower edge of the tank, being preferably keyed upon a rotatable shaft w.

All the pulleys above described are grooved when cables are used and are preferably made in the form of sprocket wheels or pulleys when chains are used.

A spur-gear f/ is mounted upon one end of the driving-shaft, which is journaled in the supportingframework in suitable metallic bearing portions 2, and a gear 4 in toothed engagement therewith is mounted upon a stubshaft 5, which is journaled in bearings 6 and 7 and provided with a belt-pulley 8 or any ordinary and well-known means for connecting such driving-shaft and gear mechanism, and thereby the chains, with a suitable source of power.

Each of the chains or cables 00 is mounted in a set of pulleys, above described, so that their outer lap extends on the outside of the tank and around the pulleys, and its inner lap hangs from the upper pulleys in the form of a swing, which extends into the tank to within a short distance of the bottom and sides thereof, as shown in the drawings. Being arranged at suitable intervals in this manner, they form a set of supports or swings arranged at the desired intervals, so that boiler-fines 9 of the same or various lengths may be supported and operated upon thereby. The rotation of the main driving-shaft will cause the simultaneous movement of all of the chains in a corresponding direction, producing a constant rolling movement of the flues, which are immersed in a suitable liquid contained in the tank and sufficient in quantity to entirely cover them, as shown by the dotted line 10 in Fig. 3, Which represents the top of the liquid.

A discharge-pipe 11 is arranged at the bottom of the tank for drawing off the liquid and extends out through the end wall of the outer frame, being provided with a suitable cock 12 for opening and closing the discharge-passage from such tank formed by such pipe.

I prefer to mount the chains so that their outer laps are on the outside of the liquidcontaining tank, the driving and idler pulleys, with their shafts, being also on the out side of the tank which contains the liquid and the fines to be operated upon. The working parts are thus so far as possible free from the action of the liquid in which the tubes are immersed and are easy of access and in position to be readily removed, repaired, or replaced. This arrangement also enables the full capacity of the inner tank to be utilized and the largest possible number of boiler-fines to be operated upon with the minimum amount of liquid and with the smallest possible tankspace, In this connection, the construction of the tank in the form described namely, U-shaped in cross-sectionis of material advantage, as it correspondsblosely to the position of the swinging portions of the chains in which the flues are suspended while being operated upon.

While I have described this invention as using a tanlrfor the holding of liquids in which the flues to be rattled are suspended, it willrbe understood that I do not desire to limit myself strictly thereto or any further than is pointed out in the claims, for the reason that the tank and fluid may be dispensed with and the flues rattled in a dry manner upon the chain mechanism.
