Abstract: The nature of my invention consists in generating steam by injecting small quantities of water into hot generators (A,) filled with balls or plates of iron heated to a proper heat which is converted into steam instantaneously, and acts upon the piston, B3, (without a boiler) and which escapes immediately upon the ascent of the piston through an aperture into the escape tube g, where the steam may be condensed, or otherwise, leaving neither water or steam to cause an explosion. The generators may be made of cast, or wrought iron or copper, either cylindrical, or square, and in proper pro- portions, the content of which being about two cubical feet more, or less according to the power of the engine, or the quantity of water to be generated into steam. These generators are to be packed full of iron plates or balls not exactly in contact in all 80 points, to retain heat, at the same time so packed as to admit the water between them, and to form as munch surface as possible to generate the steam. It is also for another important purpose which will be here explained. If the generators are not packed with iron they must of course be filled with steam to a certain power upon the square inch according to the power of the engine required, in order to obtain that elasticity 40 necessary to drive the machinery, hence it will be seen that a great body of steam would have to be discharged at every stroke of the piston, butt by filling the generators with iron, there is no more steam produced than that which is necessary to fill the cylinder; and this is regulated by the quantity of water discharged into the generators; the steam from which upon the ascent of the piston immediately escapes through the upper escape into the escape tube (g) opened by the ascent of the piston. Claim: The above mode of generating steam by introducing a jet of water into generators, nearly filled with bars or balls of iron; as above described for the purpose of generating the quantity of steam required for each action of the piston, the vent-valve above described, the arrangement of machinery, for opening, and closing the water, and vent-valves as above described, and the arrangement of machinery for causing the pistons alternately to remain at rest, thereby allowing the generators to regain the requisite degree of heat as above described.

Abstract: The stove is to be made of cast-iron, stand on four, or six legs, and may be of any size required. That part of the bottom plate of the stove directly under the oven, or rear section of the stove, is elevated a little above the front part of the bottom plate as appears by the side view drawing. There is a sunk ash pit commencing near the front end of the bottom plate, and extending as far back as the. back side of the fire chamber. Claim: The double sliding grate in front. The plan, and manner of raising the fire-grate.

Abstract: he nature, and principle of our invention consists in uniting a gridiron with a spider in such manner that both may be used together or each separately at the same time as occasionality require, the juices of the broiling me at being conducted into the spider or when the spider is separately used, into a receiver placed within it. Claim: The combination of the gridiron, and spider, and the parts necessary to form a useful connection as above specified particularly the formation of the joint as above de-scribed, and the studs, and corresponding supports to hold the gridiron at proper elevation.

Abstract: The principal feature of my improvement consists in constructing a portable fire place, with hot air chambers on the sides moving on wheels, or tracks on ways so that it may be brought as far into the room or run back into the chimney as may be desired in order to increase or diminish the heat at pleasure. Claim: The constructing and fixing a grate, or stove as herein described, as that it may slide in and out within a. finishing of sheet iron, or other suitable material as that it shall fit as closely thereto as is compatible with the necessary sliding in and out.

Manufactured by Fox Bros. - Sheffield England

Design with adjusting nut in the movable jaw working on a threaded shaft parallel to the main shank; the specifications include description of how the parts are assembled. Ron Geesin's "The Adjustable Spanner" shows two sizes of Fox Bros. DELPHI matching this design. An 1893 ad for Wm. MARPLES "ECLIPSE" lists seven sizes (6" through 18").
