ALTERNATING AIR-PRESSURE SYSTENI SPECIFICATION forming part of Letters Patent No. 615,668, dated December 13, 1898. Application tiled 111119 12,1897. Serial N0. 640,439. (No model.)
To (LM whom it may concern:
Be it known that 1, WILLIAM H. BARR, a citizen of the United States ot' America, residing at W'ichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Alternating Air-Pressures, of which the following is a specification, reference being had therein to the accompanying drawings and the iigures of reference thereon, forming a part of this speciiication, in which- Figure 1 is a plan view of my improved alternating air-pressure system, with a portion of the apparatus shownin cross-section. Fig. 2 is a side view of a cylinder. Figs. 3, 4, and 5 are details of the same. Fig.l 6 is a side view of another style of cylinder. Fig. 7 is a sectional detail of the same.
This invention relates to certain improvements in an alternating air-pressure and a mechanism for producing said alternating air-pressure; and it consists in the construction of cylinders and air-pipes and the arrangement of the same and the transmitting of an air-pressure from one pipe to another without the escape or loss of said air-pressure.
Referring to the drawings, 1 represents airpipes leading from an air pump through which air can pass into the pipes 2 and 2a. Said pipes 1 are provided with the checkvalve 3. y
4 represents an air-cylinder which is connected with the pipes 2 and 2 at either side at 5 and 6.
7 and 8 represent two piston-heads, which are secured to the ends of the piston-rod 9.
' 10 represents a piston driving-rod which passes centrally through and is integral with the ball or globe bearing 11.
12 represents a conical-shaped hood secured to the side of the cylinder 4. Said hood is provided at its outer end with a cylindrical 34, in which said ball or globe bearing 11 is adapted to freely turn, allowing the driving-rod 10 to have an oscillating movement. 13 represents a cap which is for holding said ball 11 snug against the inner wall of said cylindrical boxing 34, through the 5o medium of the set screws 14, which pass through the openings 15 in the wall of said hood and press down on said cap. (See Figs. 2 and 3.) Said cap is provided with the slot 16, (see Fig. 4,) through which said drivingrod 10 oscillates. 17 represents one end of said driving-rod passing through a slot 18 in the cylindrical boxing 34 and extending out side of said boxing, to which power can be applied for operating said rod 11, which will in turn operate the piston heads 7 and 8. Said arm 11 is also provided with the elongated opening 19, through which it is secured to the piston-rod 9 at 20. 21 represents caps on the outer ends of said air-pipes 2, closing the same. 22 represents air-feed pipes leading from said supply-pipes 2 and 2a to cylinders 24 and 27, said feed-pipes 22 entering the cylinders 24 and 27 at 23, and said cylinder 24 is provided with the piston-head 25 and piston-rod 26. 28 represents a central partition in said cylinder 27 and is for the purpose of dividing said cylinder into two separate compartments, so the steam or air from one compartment cannot enter into the other compartment.
29 represents lugs secured to the sides of the cylinder 27. Said lugs are provided with a hole through which the supporting-rods 30 pass said cylinder slides to and fro on said rods and on the pipes 23. 31 represents a divided arm secured to the said cylinder and is for transmitting power from said cylinder. 32 and 33 represent a support for said cylinder.
In use this alternating air-pressure is operated in the following manner: Air is rst pumped from an air-pump into the pipes 1, when they will by opening the valve 3 conduct the air to the pipes 2 and 2 and the cylinder 4 to any desired pressure. YVhen the piston-heads 7 and S are at one end, as shown in Fig. 1, the head 7 covers the port 5, leaving a larger space for the air in the pipe 2 than there is in the pipe 2, which will reduce the pressure in said pipe 2L and increase the pressure in said pipe 2, which when the pressure is greater in the pipe 2 passes through t-he pipes 22 into one end of the cylinders 24 and 27 forcing the pistons one way, when power can be applied to the end 11 of the rod 10, forcing said pistons 7 and 8 to the opposite end of said cylinder 4, when the cylinder-head 8 will cover the port G, at

the same .time leaving a larger space ink the opposite end of said cylinder 4 and pipe 2, which Will in turn lessen the pressure in said pipe 2 and increase the pressure in said pipe 2, which will in like manner force the piston-heads of the cylinders 24 and 27, andl as many more of said cylinders as maybe added, thus giving power to a series oi' cylinders.
When the air-pressure is in the pipe 2, it is also in the pipe 23, which carries the air into one end of the cylinder 27 and presses against the partition 2S, which carries the cylinder 27 in one direction, which in turn carries with it the divided arm 3l. In like manner the cylinder 27 and arm 3l are reversed when the air-pressure is in the pipe 2.
Having thus described my invention, what l clailnasnevsT and usefnLand desireto secure by Letters Pat-ent, is` as follows:
In the alternating air-pressure system, the combination of a cylinder having central partition therein, lugs on the sides of said cylinder, supporting-rods passing through said lugs whereby the cylinder is adapted to reciprocate upon said rods, an air-pipe entering each end of said cylinder, and means for supplyi ng air alternately to each of said pipes, and a driving-arm secured to the cylinder for transmitting power, substantially as described.
