TILTING MIXING-KETTLE.

Specification of Letters Patent.

Application led June 7, 1909.

Patented Dec. 13, 1910.

Serial No. 500,688.

kettles and more particularly to provide a combined mixing kettle of the tilting type and an attached furnace therefor; to provide a tilting mixing kettle having a furnace directly connected thereto beneath the same, and adapted to tilt therewith, and thereby avoid the necessity for removing the furnace and disconnecting it from its fuel supply each time the kettle is to be tilted; to provide a tilting mixing kettle `with an attached furnace and having a fuel supply adapted to readily adjustv itself to the position of the kettle on its support;

andto provide a mixing kettle of the tilting type adapted to have its contents either drawn off or poured therefrom and provided with improved.mechanism for automatically connecting the furnace with the outlet pipe for the products of combustion when the kettle is brought back to normal position after being tilted.

A specific construction embodying this invention is illustrated in the accompanying drawings, in which:

Figure l is a view partly in section and partly in side elevation of a device embodying this invention. Fig. 2 is an enlarged section taken on line A-A of Fig. 1. Fig. is a section taken on line B--B of Fig. 2. Fig. 4 is a top plan view of the device.

In the construction shown in said drawings, the standards or frame members l and 2 may be of any desired construction and are provided at their upper ends with bearings' and 4 respectively.

The kettle 5, which is preferably formed of copper or other noncorrosive material, is provided near its top with oppositely disposed trunnions 6 and 7 which are journaled in said bearings. Rigidly secured to said kettle, at a point slightly below said trunnions is the furnace or heater jacket 8. Said jacket is preferably riveted at its upper edge to the kettle and is closed at its bottom save for the damper or valve 9 adapted to admit air thereinto. The damper, as shown, is a revoluble disk having apertures therein adapted when in one position to register with apertures l() in the bottom of the jacket. Said furnace is adapted to burn gas for heating the kettle, and for the purpose of providing a gas supply which does not have to be disconnected when the kettle is tilted, the trunnion 7 is hollow and connected in the outer end thereof by means of a coupling 1l is the gas supply pipe 19.. Said coupling affords a gas tight joint about the pipe and permits the trunnion to be partially rotated with respect to the pipe when tilting the kettle. Leading downwardly from said trunnion 7 and into the lower portion of the furnace jacket 8 is the burner pipe 13, which is provided on its end within said jacketwith a burner 14 of any desired construction, which is situated immediately beneath the kettle.

For the purpose of carrying ofi' the products of combustion from the furnace jacket and for providing means for automatically connecting the furnace with and disconnecting it from the outlet pipe for the products of combustion, a hood 15 is rigidly secured on the frame member 2 and is provided with a flaring or bell shaped opening or mouth 16 in its side facing the direction in which the jacket moves when the kettle is being tilted. The jacket is provided in its side adjacent said hood with an opening 17, and secured to the jacket in register with said opening is the pipe elbow 18, which extends laterally from the jacket and then forwardly in alinement with said mouth 1U, and is adapted to enter said mouth and tit closely therein, as shown in Fig. 9., when the kettle in normal position. Connected in said hood is the outlet pipe 19 adapted to carry off the products of combustion.

In the bottom of the kettle is provided va drawofl' pipe 20 which extends downwardly through the burner and the damper 9, and is provided at its lower end with a gate valve 21 by means of which it is controlled. Said drawotf pipe is for the purpose of drawing off the contents of the kettle if desired instead of pouring it off. j

Rigidly secured on the trunnion 7 is a notched disk or member 22, and a locking lever 23 is pivoted on the bearing 4 and is adapted to engage with said member and hold the kettle in adjusted position.

The operation of the construction shown is as follows: When it is desired to heat the contents of the kettle, gas is admitted to the burner through the pipe 12, trunnion 7 and the pipe 13. The products of combustion from the burner pass out of the jacket through the aperture 17 into the elbow 18, and thence into the hood 15 and pipe 19. Vhen the kettle is in normal or upright position the elbow 18 projects into the hood 15 and forms a tight joint therewith. `When the kettle is tilted the elbow is withdrawn from the hood, and as the kettle swings back to place it again enters the hood. The ket tle may be tilted without disconnecting` the gas supply or interfering with it in any manner, and inasmuch as the furnace is attached directly to the kettle it does not have to be removed while tilting the kettle to pour out its contents. The drawoff pipe 20 is provided for the purpose of drawing off certain mixtures which are preferably drawn instead of poured. By means of the damper 9 the admission of air to t-he jacket may be regulated.

While but one specific embodiment of this invention is herein shown it will be understood that numerous details of the construction shown may be varied or omitted without departing from the spirit of this inven-' tion.

I claim:

1. A tilting' mixing kettle, comprising a support, a kettle pivoted on said support, a furnace on the kettle, a pipe adapted to carry olf the products of combustion from the furnace, a hood connected with said pipe and having a bell shaped opening, and a pipe leading` from the furnace and having its end tapered to lit closely in said opening when the kettle is in normal position.

2. A tilting mixing' kettle, comprising a pair of standards, a kettle pivoted on the standards, a jacket on the kettle, a burner in the jacket beneath the kettle, a fuel supply pipe leading to the burner, a hood on the in ner side of one of the standards and having a laterally opening, outwardly flaring mouth, a pipe leading from the hood, and an elbow opening from the acket and having a tapered end thereon adapted to enter and lit closely in said mouth when the kettle is in upright position.

3. A tilting mixing kettle, comprising a support, a kettle pivotally mounted on said support and adapted to be tilted, a jacket engaged on said kettle and adapted to be tilted therewith, an outlet pipe, a hood on the support and connected with the pipe,

l and an elbow on saidv jacket adapted to automatically connect with the hood and afford conin'nniication between said pipe and acket when the kettle is returned to normal position.

et. A tilting mixing kettle, comprising a kettle, means pivotally support-ing said kettle.a heating jacket on the kettle, an outlet pipe for said jacket, and telescoping means adapted to automatically connect the jacket therewith when the kettle is turned to normal position.

5. A tilting mixing kettle comprising a frame, a kettle pivotally supported thereon, a heating jacket beneath saidkettle and supported therefrom, a pipe on said frame, a hood connected with said pipe, and a curved pipe opening from said jacket and adapted n hen the kettle is swung to normal position to enter said hood and afford communication between the jacket and pipe.

6. A tilting kettle, comprising standards, a kettle, trunnions on said kettle and journaled in said standards, one of said trunnions being' hollow, a jacket secured on said kettle, a burner therein beneath said kettle, a gas supply pipe, means connecting said pipe with the hollow trunnion and adapting the trunnion to rotate with respect thereto, a pipe leading from the trunnion into the jacket and connected in said burner, a hood carried von one standard, a curved pipe opening from the jacket and adapted to enter the hood .when the kettle is in normal position,`

and a pipe leading from the hood.

7. A tilting kettle, comprising standards, a kettle, trunnions on said kettle, having bearings in said standards and one of which is hollow, a jacket on the under side of said' kettle, a burner therein, a pipe leading from said hollow trunnion to said burner, a supply pipe connected in said hollow trunnion, a damper in the bottom of said jacket, a valved controlled drawoff pipe leading downwardly from the bottom of said kettle through said burner and damper, an outlet pipe supported on one of the standards, and interfitting means on the jacket and standard adapted to afford communication between the jacket and the outlet pipe.

In testimony whereof I have hereunto subscribed my name in the presence of two witnesses.
