Specification of Letters Patent.

Patented Apr. 25, 1911.

Application filed April 5, 1910. Serial No. 553,515.

To all whom it may concern:

Be it known that I, JOHN NORIN, a subject of the King of Sweden, residing at J ersey City, in the county of Hudson and State .of New Jersey, have invented new and useful Improvements in Rotary Engines, of which the following is a specification.

This invention relates to motors or more especially to that class of motors known as rotary engines which are adapted to be driven by steam or gas and are provided with a rotating piston.

The present invention is adapted to provide a backing or purchase for the operating fluid which is confined between the said backing or purchase and the rotating piston so that the latter is impelled forward by the motive fluid confined behind it, but by means of certain mechanism this backing is at regular intervals removed or disposed with so that the piston passes on while the backing is again brought in position to affect its work.

These and other objects and details of the invention are more fully explained and described in the following specification, set forth in the claims and illustrated in the accompanying drawings, where:

Figure 1 is a side elevation of the motor showing the mechanism for operating the backing for the motive power. Fig. 2 is a similar view with the side plate removed to illustrate the operation of the interior of the motor. Fig. 3 is a longitudinal sectional view. Fig. 1 is a side view of a modified form of the motor. F ig. 5 is a cross sectional view of same. Fig. 6 is an end view of the modified form.

In the operation of a motor such as shown in the accompanying drawings, it is preferable that two cylinders 10 and 11 are employed and which are connected at adjacent sides so that the steam or other motive fluid may enter the pipe 12 and pass into a chamber 13 having therein a rotating valve or cut off 14 which opens and closes inlet ports 15 and 16 and admits the steam to the respective cylinders 10 and 11. These inlet ports are immediately above a horizontally arranged disk 17 intersecting both of the cylinders and playing in a groove 18 of the hubs 19 at the center of each cylinder and carrying the pistons 20 and 21. These pistons 20 and 21. fill the space between the hub and the inner surface of the cylinder and act as a barrier to prevent the steam from passing from one part of the cylinder to the other and in the disk 17 is cut an opening 22 to permit of the passage of one of the pistons as it rotates and as the disk intersects the interior of the cylinder as shown in Figs. 2 and 3, it normally acts as a backing for the motive fluid while it acts on the pistons until the piston has passed around the cylinder and approaches the disk when the opening 22 is brought into position.

The shafts 23 of the hubs 18 are provided with worm gearing 24: and a shaft 25 which causes them to work in unison and this shaft also carries a worm wheel 26 gearing with a similar wheel 27 on a shaft 28 which carries and rotates the disk 17 so that the opening 22 passes into each cylinder as its piston 20 or 21 is about to pass the disk. The balance of the disk therefore, becomes a backingfor the motive fluid which is supplied by means of the inlets 15 and 16 between the disk and the pistons so that the latter are moved forward and the fluid in advance of them is exhausted from the ports 29 and 30 at one side of the motor frame.

Themodified forms shown in Figs. 4, 5 and 6 dispenses with the worm gearing and in its place are employed a number of hell crank levers with balls and sockets to accomplish the same result. The ends of the shafts 23 carry socketed arms 37 and in the sockets are held the balls of arms 31 projecting from a sliding rocking shaft. From this shaft also projects a depending arm 32 having a ball working within a socket at the upper end of an arm 3 1 also carried by a rocking and sliding shaft 33. The other end of this shaft 33 carries an arm 34 connected with an arm 37 located at the lower end of the stem of valve 35 and when the shafts 23 rotate the arms 31 are rocked and shifted giving a similar motion to the arm 32 which in turn rocks and shifts the shaft 33 and the arms 34 and 34 and finally rotates the arm 37 and the valve stem. The arms 37 and 37 are provided with counterweights and the valve 35 is similar to the valve 14 above described. The reversing of this motor is accomplished by means of a toothed bar 40 operated by means of a lever 40, the teeth of which gear with the teeth of a shift ing disk 42 adjacent to the rotating disks 4:2 which are carried by the shaft 23 and described heretofore but the latter valve operating mechanism produces less friction and may be found more desirable.

In assembling the frame of the motor, a semi-circular framing 36 projects from each side of the motor to accommodate the disk 17 and in practice, it Will be found unnecessary to provide anypacking for this disk as the steam or vapor used to dry the device Will be found adequate to prevent the leakage or passage of vapor from one part of the motor to the other.

It is obvious that the motor may be other- Wise modified and its parts altered, Without departing from the essential features above described.

What I claim as new and desire to secure by Letters Patent is:

1. In a motor, the combination With adjacent cylinders, of pistons rotating in the cylinders, a valve mounted on a stem and a disk carried by the valve stem and intersecting the space Within the cylinders, and having a passage for the pistons to pass through; and driving means connecting the pistons With the valve stem.

2. In a motor, the combination with adjacent cylinders, of a valve mounted on a stem between the same, a rotating disk carried by the valve stem to intersect the interior of the cylinders and having an opening for the passage of the pistons and driving means connected With the pistons for causing the cylinder to alternately intersect the cylinder chamber.

In testimony whereof I aflix my signature in presence of two Witnesses.

JOHN NORIN.
