F denotes the toothed bar having the longer 50 Likeletters of reference designate correradius, and F the toothed bar having the 10 shorter radius. Said racks F and F are therefore preferably of unequal length, the one of the shorter radius having the shorter length. When the device is in the position shown in Fig. 1,the vibrating frame B is moved up and down by means of the handle D-that is to say, it is oscillated vertically. When the device is in the position shown in Fig. 3, the vibrating frame is moved from right to left. that is to say, by grasping the handle D the vibrating frame is oscillated horizontally.

The frame Bis provided with a flange 13, which lies in a groove beneath the guideflange T, which is securedv to the outside of the frame A, and by means of which, therefore, the frame is guided in its movements.

Referring to Fig. 1, E designates a vertical bar, which is adapted to reciprocate vertically. This bar may belong to a windmill and may be reciprocated by a connection with said mill. It may of course belong to any other kind of a machine and may derive its actuating-power from any source. As represented in Fig. 1, it moves in guides at a, secured to the main frame A. It is provided with a horizontal projecting pin a, which enters a slot I) cut in a suitable part of the frame Bas, for instance, in one of its spokes when said frame is made in the skeleton pattern shown in Fig. 1. Slot b is long enough to give the pin 0 sufficient play during the oscillation of the frame B. As the rod or bar E moves up and down it will be clearly manifest that the result thereof will be to oscillate the frame B. Thus it will be seen that this oscillating or vibrating frame may be actuated either by hand or by connection with some suitable power applied thereto by a shaft driven by some machinery.

In the mainframe A (or A, as the case may be) there is journaled a horizontal shaft L, having thereon a gear-wheel M. Parallel to shaft L is another shaft J, carrying a small pinion K, which meshes with the gearwheel M. (See Fig. 2.) The shaft J also carries a band wheel or pulley J on the end thereof outside of the frame A. This wheel J may serve as a balance- Wheel or as a pulley to carry off power to any suitable machinery which it may be desired to run. On the shaft L are also two gear-wheels H and I. These wheels are loose on shaft L. Between them is an intermediate disk R, having a suitable hub projecting on each side and keyed to the shaft L. (At this point observe particularly Figs. 4, 5, 6, and 7.) The gear-wheels II and I have their faces which are opposite each other, or, in other words, their faces which lie next to the intervening disk, are provided with recesses, the edges of which recesses are notched to form ratchetteeth. Thus the wheel H is provided with a series of ratchet-teeth h, cut in the edge of the recess in its face, and the gear I is provided with a circular series of ratchet-teeth 2', cut in the edge of the recess in its face. The disk R is provided on each side with a pair of pawls S S, suitably pivoted to the opposite faces of the disk.

s 3 denote springs acting against these pawls to force them into engagement with the ratchet-teeth h and 11, respectively. The ratchet-teeth of the two gears are cut with their points projecting downwardly, so that the pawls S S may operate properly in connection therewith. The gears II and I are of unequal diameter, the gear I being the larger. These gears H and I are so placed that the gear I will engage the rack-bar F and the gear II will engage rack-bar F. Since the rack-bar F is curved on an are having a shorter radius than the radius of arc of rackbar F, it will be obvious that the teeth thereof will travel through a shorter distance than the teeth of rack-bar F during each vibration of the frame B, and therefore it is necessary that the gear H, which engages the rack-bar F, should be of less diameter than the gear I, which engages the longer rack-bar, in order that the impulses of rotation which are given to the shaft L at each vibration of the frame B may be equal.

When the frame 13 is vibrated in one direction, it will be obvious that gear H will rotate in one direction and gearlwill rotate in a reverse direction. (See the arrows in Fig. 1. by the pawls S S on the disk R that it will be locked to said disk, and the rotation of the gear will be communicated to the shaft L, whereas the other gear will be moving in such a direction that the pawls S S on the side of the disk R will slip idly over the ratchet-teeth at the next vibration. The gear which was idle on the preceding vibration will become active, inasmuch as its direction of rotation will be reversed, and therefore it will engage the pawls and communicate arotative motion to the shaft L, while the other gear, which was active before, is now idle.

Thus at each vibration of the shaft B one of the gears will operate to communicate a rotary motion to the shaft L. The rotary motion of shaft L will be continuously forward or continuously backward, as the case may be, inasmuch as this actuation of the gears will result in rotating the shaft L continuously in one direction. Therefore the pulley J will be driven with apositive constant forward motion or backward motion, as the case may be.

My improved machine for converting reciprocatory into rotary motion may be placed in the position shown in Fig. 3, where the 0s cillating frame is seen as vibrating in a horizontal direction, and J designates the belt passing around the band-wheel J, which belt can be connected with any suitable machine or device which it may be desired to drive. Another application of my improved device for converting motion to do actual work is represented in dotted lines in Fig. 1. In this figure the frame B is shown as provided with a bar G, located at right angles to the handle One of these gears will be so engaged D and having, the pivot B, on which the oscillating frame swings, serving as a pivot on which the bar G can be vibrated. This bar is formed as a part of the vibrating frame and is located at the pivotal point B. O 0 denote, wires, cables, or cords connected to the opposite ends of the bar G; These cables or cords may have any suitable length, and therefore may be run to any desired distance, and their other ends are connected to the opposite ends of a bar 0, which is similar to bar G and is pivoted at its center at 0', said bar 0 being provided with an arm P, which is slotted, its slot receiving a pin on a rod or bar N. It will thus be seen that the oscillation of bar G will serve to oscillate the bar 0, and this will in turn communicate a reciprocatory motion to the rod N. Thus the power of myimproved device may be communicated to a pump or-other apparatus to actuate the same in any desired manner.

Numerous details and changes may be made in the construction and relative arrangement and adaptation of the several parts as experience may suggest, and I reserve the liberty of varying the details of the invention as necessity and practice may require or advise.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device for converting motion, the combination of an oscillating frame having a curved slot provided ,with parallel rack-bars and a horizontal shaft, together with gearwheels on said shaft-,and an intermediate pawl provided disk whose pawls engage ratchet-teeth formed in the faces of the said gears, which gears are engaged by the aforesaid rack-bars,.all combined and arranged so that when the frame is oscillated the shaft on which the gears are located will be rotated continuously in one direction.
