Gridiron
|
Merwin McKaig |
Cumberland, Allegany County, MD |
Walter J. Muncaster was the plant superintendent for W. W. McKaig & Son foundry.
Abstract:
he object of the invention is to produce a cheap gridiron, which may have its cover readily applied in an airtight manner, in order o retain the heated gases, &c., in contact with the upper surface of the meats, and there by effect the cooking of both its sides at once.
Claim:
The combination of the cast-metal body A, having the wide, flat inclined faces a, and the cover B, having the flat inclined flange b, fitting over and around the body, as shown, whereby a wide bearing is obtained, and a close union of the parts insured upon forcing down the cover. |

Raising and Lowering Screw Propellers
|
Merwin McKaig |
Cumberland, Allegany County, MD |
Walter J. Muncaster was the plant superintendent for W. W. McKaig & Son foundry.
Abstract:
The prospect that steam will soon supersede animal power in the propulsion of boats on canals has led to many improvements in the structure of engines, &c., with a view to their adaptation to the peculiar requirements of canal navigation. A principal requirement of the 3ase is facility for raising and lowering the propulsion-wheel; because, when loaded, the boat will barely clear the bottom, and said wheel must then be entirely above the line of the keel, and when unloaded she draws but a few inches of water and the propulsion-wheel, if unchanged in position, would not then be sufficiently submerged. It has therefore been heretofore proposed to place the engine upon a horizontal frame, mounted upon transverse bearings, about midway between the said engine and said wheel, so that as the said wheel is lowered the engine is correspondingly raised, and vice versa. The purpose of this arrangement is to simplify the structure, to enable the engine to apply its force directly to the rotating shaft at all times, because their relative positions are always unchanged, and to dispense with universal joints, or substitutes therefor, in changing the direction of motion. This principle of structure has been employed with paddle and screw-propellers; and hence we do not claim anything more than the peculiarities of structure hereinafter fully described, whereby a vertical engine and screw-propeller are rendered more simple in structure, compact, and efficient, and the propeller and engine more readily handled than heretofore.
Claim:
The vertical engine-frame B, mounted upon trunnions A, and provided with the tubular arm C, extending through the stern of the boat and provided with the boxes G G and D, combined with the crank-shaft F, mounted in said boxes. |

Metal Bending and Straightening Machine
|
Walter J. Muncaster |
Cumberland, MD |
Walter J. Muncaster was the plant superintendent for W. W. McKaig & Son foundry.
Abstract:
My invention relates to apparatus or machinery for straightening shafting; and it consists, primarily, in a traveling press adapted to sustain the shaft and to exert the required pressure or force thereon, the press being adapted to travel lengthwise of the shaft and thus to act upon every portion thereof.
Claim:
In a machine for straightening metal, the combination of a frame and a traveling press provided with rests or supports for the metal to be straightened, wholly independent of the bed or frame of the machine upon which the press is supported, and open at the upper side to permit the shaft or bar to be placed upon or removed from the rests laterally. |

Metal Bending and Straightening Machine
|
Walter J. Muncaster |
Cumberland, Alleghany County, MD |
Walter J. Muncaster was the plant superintendent for W. W. McKaig & Son foundry.
Abstract:
My invention relates to machines for straightening and bending metal bars and io shafting, and is designed as an improvement upon the machine for which Letters Patent were granted to me bearing date the 9th day of June, 1885, and numbered 319,603.
Claim:
In combination with a bed or supporting frame, a press movable on said frame, transverse frames resting upon said bed, beams pivoted in said transverse frames and provided with rollers to sustain a shaft, rack-bars attached to the beams, and a shaft extending lengthwise of the main frame and provided with pinions to mesh with the rack-bars. |
