IMPROVEMENT IN TOY STEAM-ENGINES.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern Be it known that I, PHILANDER MACY, of Rochester, in the county of Monroe, and State of New York, have invented certain new and useful Improvements in Toy Steam-Engines; and I do hereby declare that the following is a full; clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a sectional elevation of my invention.
Figure 2 is a vertical central section of the valvebox and part of the cylinder, the full lines showing the induction-passages open, and the red line indicating the position of the valve when the exhaust-passage is open to the cylinder.
Figure 3 is an elevation of the plug-valve a..
The object of my invention, the nature of which will be understood' by reference to the drawings and specification, is to produce a cheap and simple toy-engine, devoid of danger, and which can be readily managed by a child.
To cnableothers to make and use my invention, I will describe its construction.
1 make the boiler A in the form of a hollow circular disk, composed of a fiat bottom-plate, e, and-a concave top-plate, f, which are joined at the periphery with a fold, in the usual manner.
The plate f may oe crimped in any desired orna mental form, so as to give sufiicient steam-room.
The vertical stay i is soldered to both plates, to prevent bilging or bursting.
The large bottom e aiiords considerable heating-surface, and since the water is necessarily shallow, steam is raised quite rapidly, when the boiler is placed over a gas-jet or lamp, or set upon a hot stove.
Upon the top-plate of the boiler, I erect a singleacting toy-engine, composed of valve and box C, cylinder B, beam D, and crank-shaft and dy-wheel E, the
valve-box having direct communication with the small steam-dome b, through the pipe y.
The connections between the working-parts are al1 made by means of wires bent to the proper shape. The beam vibrates upon the wire-support d, soldered to the cylinder. The main links are connected to the piston by a short wire, soldered to the piston-rodat right angles to it, as shown in 6g. 2. The piston-rod is guided by a small wire, looped around it, and soldered to the cylinder. The crank-shaft supports are given two orl three turns aroundhe shaft, to form bearings, and are soldered at their lower ends to the boiler. These parts can also be made of sheet-metal, punched out by dies and bent to the proper form.
The valve-box C is bored out either straight or tapering, to receive the plug-valve a, figs. 1, 2, and 3, which is tted steam-tight to it, and worked by the rod b', hooked at one end to the main crank, and at the other to the arm` c of the valve.
The valve-box has formed within it the inductionpassage y, the cylinder-port z, and the exhaust-passage x, all communicating with the valve-chamber, at
a distance of one-quarter of the circumference apart.
Across the valve a, at a proper point to register with these passages, I cut the channel a', figs. 2 and 3, to such a depth which shall allow a full opening of two Vpassages at once, at each extremity of the throw, which'throw must consequently be one-quarter of a circumference. The two extreme positions of the valve are shown by the black and red lines in Iig. 2(
The valve is kept in its place by a washer and pin, as shown in g. 1.
A safety-valve, o, may be applied at any convenient point on the boiler.
The boiler may be constructed of any kind of sheetmetal, tin-platebeing preferred as the cheapest.
What I claim as my invention, and desire t'e secure by Letters Patent, is
l. The construction and arrangement of the boiler` 2. The arrangement of the boiler A, passages x y z, valve c, channel a', cylinder B, support d, beam D, and connecting valve-rod b', all constructed substantially as herein set forth.
