US Patent # 514,169 & # 517,900
The invention is based upon certain well known mechanical principles a statement of which will assist in a better understanding of the nature and purposes of the objects sought and results obtained. In order to describe the best manner of which I am aware in which the invention is or may be carried into effect, I refer now to the accompanying drawing which represents in central cross-section an engine embodying my improvements. A is the main cylinder in which works a piston B. Inlet ports CC pass through the sides of the cylinder, opening at the middle portion thereof and on opposite sides. Exhaust ports DD extend through the wall of the cylinder and are formed with branches that open into the interior of the cylinder on each side of the inlet ports and on opposite sides of the cylinder. The piston B is formed with two circumferential grooves EF, which communicate through openings G in the piston with the cylinder on opposite sides of said piston respectively.
The cylinder I is without ports of any kind and is air-tight except as a small leakage my occur through the bearings V, which experience has shown need not be fitted with any very considerable accuracy. The cylinder I is surrounded by a jacket K which leaves an open space or chamber around it. The bearings V in the cylinder I, extend through the jacket K which leaves an open space or chamber around it. The bearings V in the cylinder I, extend through the jacket K to the outside air and the chamber between the cylinder and jacket is made steam or air tight as by suitable packing. To explain now the operation of the device above described. In constructing the apparatus I allow for a variation in the length of stroke by giving to the confining cylinder I of the air spring properly determined dimensions. The greater the pressure upon the piston, the higher will be the degree of compression of the air-spring, and the consequent counteracting force upon the plunger.
As an instance of the uses to which this engine may be applied I have shown its piston rod connected with a pawl R the oscillation of which drives a train of wheels. These may constitute the train of a clock or of any other mechanism. A description of the principle of the construction and mode of operation of this device is necessary to an understanding of my present invention. Referring to Figure 1, A designates a cylinder containing a reciprocating piston B secured to a rod C extending through on or both cylinder heads. DD; are steam ducts communicating with the cylinder at or near its ends and E is the exhaust chamber or passage located between the steam ports. The piston B is provided with the usual passages FF鈥?which by the movements of the piston are brought alternately into communication with the exhaust port. G designates a slide valve which when reciprocated admits the steam or the gas by which the engine is driven, from the pipe G鈥?through the ducts DD鈥?to the ends of the cylinder.
It was silver, gray leather, LOADED(!) and it had a very rare (at least in the US) 5-speed manual. And he could get me in the car for less money then my budget. A lot less money. I asked him. Easy鈥t had a manual transmission, nobody wanted a BMW 5-Series with a manual transmission. Picked it up on a very rainy night, it was pouring. So of course I had to completely detail it the next day. I loved that car; it was awesome. But it was doomed too. I was making pretty good bucks in the Dot Com space and I realized I could get rid of the BMW and get back into a Porsche. It went up for sale. 1500 cash. Hey, you gotta do what you gotta do鈥r can get away with. So picture this, struggling musicians pulling up in a variety of barely running cars and trucks, getting out and lugging old nasty amps and such, dressed in grungy jeans and tee shirts. I pull up in a new BMW 5-Series, pull out a new Ashdown amp and am dressed in my hip Armani duds鈥he juxtaposition was interesting to say the least.
