WILLIAM FARR GOODWIN in STELTON (New Jersey State, V. S. Α.). Device for converting a reciprocating motion into a rotating one.

Patented in the German Empire on January 8, 1878.

The purpose of the present invention is to convert reciprocating movements into rotating ones, avoid dead spots and create a uniform rotation; further on all pivot points of the shaft both normal and parallel to the direction of its axis to establish a perfect equilibrium of forces, so that a loss of force through friction against the camp is avoided.

For this purpose, the inventor attached a screw thread to the shaft Disc and make it work with two similar surfaces connected to the piston and receive their movement from it. The moving force acts in the direction of the axis of rotation of the one to be rotated Wave.

In order to establish a force balance on all pivot points, the inventor uses a second one of the device of the same type as described above, the position of which on the shaft is that of the first device is wholly or almost wholly opposite. This purpose is also achieved by that both screws are cast together in one piece, whereby one with a double thread provided screw is created. About the balance of forces in the direction of the axis of rotation To obtain the shaft, the pistons are arranged in such a way that they mutually end their ends lift.

In Fig. Ι the accompanying drawing, a way to attach the thread is shown.

Fig. 2 shows a second type as applied to a shaft and a steam engine.

FIG. 3 is a front view of that used in the FIG. 2 arrangement Screw washer.

Figures 4, 6, 7, 8, 9, 10, 11 and 12 are Construction changes.

Fig. 5 is a front view of the screw washers used in Figs. 4, 6, 7 and 8; and

FIG. 13 is a front view of the cylinder as it is used in FIG.

As mentioned, Figure 1 illustrates the construction of a threaded cylinder (Disc).

If you want to use a screw thread, which the wave with every reciprocating Movement of the piston lets you make one revolution, you take out a cylinder Wood or other suitable material, which consists of two connected parts. The cylinder must be so long that a right-hand thread can be made on one side while the other side can be made with it is provided with a left-hand thread. After making these threads, the two Parts of which the cylinder consists, taken apart, and the right-hand and left-hand threads so connected that their relative tips are opposite to one another and the forms shown in FIGS. 2, 10, 11 and 12 form.

A double-threaded screw is used to secure the shaft at every two reciprocating movements of the piston once to turn the cylinder off four parts made, which after making the screw threads are taken apart and to be reunited. Those shown in FIGS. 4, 6, 7 and 8 then arise To shape.

The same applies to a larger number of gears.

When the device is used, it turns into a reciprocating motion to transform, every screw motion gives the oscillating piece a back and forth motion, if, on the other hand, a reciprocating motion is converted into a rotating motion, each screw turn requires a reciprocating motion of the piston.

With a movement mechanism of this kind it is necessary to make the screw surfaces well to keep lubricated. For this purpose the mechanism is in a. air and oil tight Chamber enclosed, which contains enough oil to keep the parts permanently slippery keep. This airtight chamber also serves to keep all foreign matter which the working parts block or damage it.

With this movement mechanism, the force acts in a direction parallel to the axis of rotation and is evenly distributed to all points around the axis, and it becomes evenly distributed exercised on all points from the center to the periphery, from which it is completely uniform Pressure distribution equal to that of that

Claims (2)

Steam exerted on the flask. This force is parallel to the axis and turns the shaft without lateral friction between the pins in their bearings. In Fig. 2 A A is the frame for the movement mechanisms, the steam cylinder and the shaft B, the bearings of which are mounted on cross pieces a a. C is a screw thread which rests on the shaft and C1 C1 are corresponding parts attached to the inner surfaces of the cylinder E. The cylinder E slides in corresponding guides. The steam cylinder is divided into two compartments or chambers FG, which form two independent cylinders. The piston of the cylinder F is connected to the chamber E, the piston of the cylinder G is connected by the rods g to the cylinder D, in which the screw cutouts on the shaft and the cutouts on the inside are enclosed. In this way, the power of both cylinders to drive the shaft is connected. The piston of cylinder G follows the piston of F somewhat, in such a way that the former is still in its full stroke when the latter has completed its and is moving in the opposite direction. The steam can be controlled in the usual way. As can be seen from FIG. 4, it is also possible to use only one cylinder, which serves as a steam cylinder and contains the screw mechanisms. Here the rear sides of the reciprocating screw cutouts F F1 are used as pistons and are connected to one another by a sleeve / sliding on the shaft B. The steam is fed in alternately at α and b. The cylinder A can be made of one piece and divided in the middle by a riveted partition, or it can also be made of two pieces which are then fastened to the partition by bolts. With this arrangement the pistons do not rotate with the shaft, which is achieved by providing the cylinder with a rib on its inner surface which engages a groove in the piston. The arrangement of the screw sections in FIGS. 4, 6, 7 and 8 is such that two reciprocating movements of the pistons are required for one revolution of the shaft. In Fig. 6 the cylinder has three compartments, of which A is the steam cylinder, A * A'1 contain the movement mechanisms D E, the latter slide freely in the relevant compartments and are connected to the pistons by two pairs of rods dd, ce. In Fig. 7, the screw mechanism is connected to an ordinary steam engine. The screw sections F1 F1 sit in the cylinders D E, which in turn sit on the shaft B; the screw sections FF are connected by the sleeves // with which they form one piece and by cross heads to the levers L, which have their pivot points on opposite sides of the shaft B on the cross heads, which prevents the sections FF from rotating. The levers are moved back and forth by the pistons of the steam cylinder A. The device in FIG. 8 is similar to that in FIG. 6, with the difference that the mechanism containers are used here as pistons which reciprocate on the shaft B. The steam is fed in alternately at a, b, c, d. The screw sections CI sit on the shaft and move the same under the action of the screw sections FF contained in the containers D E. Figures 9 and 10 are different views of Figure 8 and show the pistons in different positions. V V are approaches of the container D E, with which these slide in the grooves of the outer cylinder and are prevented in this way from turning. In Fig. 10 there is shown another system of steam supply a, b, c, d and Fig. 11 is a modification of Figs. 6, 9 and 10; here the pistons are connected to the moving containers by sleeves ff, which slide freely on the shaft B and enter the moving containers through sealed openings. The steam is allowed alternately at abc. The outer cylinders A serve here as steam cylinders. 12 shows another modification. Here, three screw mechanisms DEEX are used, which are seated on the same shaft in a cylinder A which is open at the ends. The DEE1 containers serve as pistons and steam cylinder lids and are sealed for this purpose. The steam is admitted alternately between DE and DE1, whereby the cylinders EE1 are moved in opposite directions, so that when one moves outwards, the other is moved inwards by the helical parts seated on the shaft, at the given moment to be moved outwards again by the force of the steam. In all these constructions the steam is kept away from the screw surfaces and the latter is well lubricated. Likewise, the rotation of the pistons or the movement containers or helical disks serving as pistons and, as a result, also the rotating friction, are avoided. Patent claims: 1.
