JACOB M. ROHM, OF GAPSVILLE, PENNSYLVANIA.

KETTLE-SUPPORTER.

SPECIFICATION forming part of Letters Patent No. 425,701, dated April 15, 1890.

Application filed January 31, 1890. Serial No. 338,798. (No model.)

T all whom. it may concer/1,;

Be it known that I, JACOB M. ROHM, of Gapsville, in the county of Bedford and State of Pennsylvania, have invented a new and useful Improvement in Kettle-Supporters, of which the following is a full, clear, and exact description.

Where'largekettles are employed to contain liquids of different kinds which have to be heated either in the open air or under cover, it has been usual to seat these vessels over a tire upon a ring of metal that is provided with three or more legs; or ahorizontal metallic bar supported at its ends has been frequently used to support a large heavy kettle in suspension over the iiame.

As usually supported over a lire, it was difficult to move a kettle laterally or adjust it vertically when this was necessary. to renew the fire or aford room for another kettle over the flame.

One object of my invention is to provide an adjustable device for the support of a kettle over a Iire, whereby heavy and large kettles may be raised or lowered while in use, as occasion may require, the change of position being rendered safe and expeditious by the simple devices provided.

A further object is to furnish a means for the support of two or more kettles over la tire which will permit the safe elevation or lowering of the kettles while suspended, as well as their lateral adjustment on the support.

Vith these ends in view my invention consists in the construction and combination of parts, as is hereinafter described, and indicated in the claims. y

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the main por tion of the device with the extension-bar removed. Fig. 2 is a top plan view of the portion of the kettle-support shown in Fig. l.

Fig. 3 is a side elevation of the complete device connected and erected to afford support for several kettles; and Fig. 4 is an enlarged sectional elevation of a portion of the extension-bar and suspension-bar, showing the manner of removably attaching the former to the latter-named piece.

A represents an upwardly-dished circular cap-plate having spaced radial notches cut in the edge a proper depth to receive the ends of the bent legs B, as shown at a in Fig. 2, where one leg is broken away to expose the slot. Upwardly projecting flanges a are formed on the opposite edges of Athe radial slots a, which are transversely perforated to receive pins a2, that are inserted through the perforated ends of the legs B and hold them jointed to the plate A, so that they may be spread apart sufliciently to afford a substantial support for the plate.

At a proper distance from the lower ends of the legs B staples b are secured to project therefrom and receive a chain or wire rope (not shown) which may be therein inserted and made to encompass the legs, said iiexible fire-proof stand or chain being adapted` to limit the outward spread of the legs B in an obvious manner.

At the center of the cap-plate A a T-shaped aperture is formed, which receives the vertical suspension-bar C, said bar having a series of ratchet-teeth cut on one face, which teeth hook downwardly, producing a rack c thereon. Two parallel flanges d are formed on the upper side of the plate A, which eX- tend from the side of the bar C that has ratchet-teeth on it, and are spaced apart of'a width about equal to that of the ratchet-cut rack c, for the introduction of a lever D, which is provided with an upwardly-bent toe d', that will engage the ratchet-teeth on the rack c and by avibration of the lever elevate or lower the suspension-bar C. On the upper edge of the flanges d, at a suitable distance from the rack c, there are opposite ears e formed, which are perforated laterally to be pivotally connected to the upwardly-proj ected pawl f, which latter is curved toward the rack c and shaped on its free end to engage the ratchet-teeth of the rack.

On the outer end portion of the lever D a short rocking tripping-lever g is'pivotally attachedby the intermediate short links g. Said tripping-lever, extending toward the free end of the main lever D, may be operated conveniently therewith or separately. An ear 71. is formed on the tripping-lever g, in which the link-bar h is loosely secured, said rod being hooked into a perforation in the IOO - teeth of the rack c.

Upon the lower end of the suspension-bar C a hook t is made to depend, on which a kettle E is hung when in use. In operation this portion of the device may be employed when one kettle only is to be used, and it is evident that by a proper manipulation of the levers D and g the bar G may be adjusted for height to suit the lire which is to be placed below the kettle E. Vhen several kettles are needed to Veffect the work required in the matter of heating liquids of any kind,.a long metal bar F is conjunctively used. Said extensionfbar F is of such dimensionsthat ample room is afforded to suspend two or more kettles thereon, and to facilitate the same the bar is supported at its outer end on a tripod G, the legs k of which are furnished with staples m for reception of a binding chain or wire` rope n, (see Fig. 3,) which, when it is bound around the legs, will prevent them from spreading and permit these legs to be drawn toward each other or spread apart, and thus change the height of the tripod as may be necessary. The inner endof the extension-bar F is provided with a projection o', which will enter one of the series of perforations o made for its introduction in the side of the suspension-bar C, so that this end of the extension-bar may be elevated with the suspension-bar by manipulation of the main lever D and tripping-lever g, any degree of elevation being retained by the interlocking action ot the pawl f. Upon the extensionbar F the bracketsupporting pulleys p are placed so that these may roll thereon, the depending hooks p providing means for the removable suspension ofone or more kettles thereon.

In operating the device with the extensionbarportion in use the tripod G is adjusted to support the outer end secure at `a proper height and the inner end elevated with the ratchet and -lever mechanism, already 1 explained, to bring the extension-bar F level.

Should it be desired to move the kettles in or out on the bar, this can be done Without handling them by raising or lowering the inner end of the bar F, when 'by gravity the kettles will roll out or in on the bar, as may be required, whereby a kettle may be removed from the fire or returned over the lire in a safe and easy manner; or a'bar with a hook at its end maybe made to engage the holes in the ears r and move the kettles.

It is to be understoodY that the suspensionbar C may be used to support a kettle along with the extension-bar hooks p', so that several kettles may be simultaneously in use to heat liquids.

`this aperture, and a pawl pivoted on these flanges, of a main lever adapted to engage the teeth of the rack and pass between the radial flanges to effect such an engagement, a trippinglever pivoted on the main lever, and a connecting link-bar loosely secured to the tripping-lever and pawl, substantially as set forth.

2. The combination, with a cap-plate pro vided with a central aperture and legs adj ustable thereon which are pivoted near its edge, a suspension-bar havinga ratchet-cut rack and a series of perforations in its side, which bar may slide inthe aperture of the cap-plate, flanges on the cap-plate which extend outward from the rack parallel to each other, a main lever which may engage the rackteeth, a tripping-lever pivoted on the main lever, and a link-bar which connects the pawl and tripping-lever, of an extensionbar that is supported on a tripod at one endV and has adjustable connection with the suspension-bar that slides in the cap-plate, substantially as set forth.

3. A kettle-support comprising a circular cap-plate, bent legs pivoted thereon, a sus, pension-bar having a rack and hook on it, which bar slides in a central aperture in the cap-plate and has a `series of perforations in its side, radial iianges on the cap-plate, apawl pivoted thereon, a main lever which is adapted to slide between the radial flanges and e11- gage the rack-teeth, a tripping-lever pivoted on the main lever :near its free end, a connecting-link for the tripping-lever and pawl, an extension-,bar which is removably attachable to the suspension-bar by engagement with its perforations, a tripod, and a series of bracketpulleys which may roll on the extension-bar, substantially as set forth.
