MEANS FOR CONVERTING MGTION.

Application fiIed May 13, 1913.

To aZZ witam it may concern:

Be it known that T, FREDERICK H. DRY- Dnn, citizen of the United States, residing at Montgomery City, in the county of Montgomery and State of Missouri, have invented certain new and useful Impi'ovements in Means for Converting liotion, of which the following is a specification.

This inrention relates to means for con- Verting reciprocatory into rotary motion and has for its primary object the provision of means whereby a windmill which has been designed more particularly for pumping purposes alone may be adapted to operate other machinery. i i

A secondary object of the invention is to overcome dead centers in the operation of the inechanism and other objects of the in- Vention will appear-'as the description of the same proceeds.

The invention is illustrated in the accompanying crawings and consists in certain novel features which will be particularly pointed out in the clain'is following the detailed description.

In the drawings: Figure 1 is an elevation of windmill having my improved device connected therewith Fig. 2 is a section taken on the line 2 2 of Fig. 1 and on a larger Scale; Fig. 3 is an enlarged elevation of my improved mechanisni; Pig. Li is a diagraminatic view.

Tn the drawings, 1 designates an ordinary windmill tower upon the upper end of which is mounted a wind-wheel 2 having a driving shaft 3 equipped with a crank 4, and 5 designates a plunger connected at its upper end to the said crank by a pitman 6 in the usual manner.

lfn carrying out my invention, I employ a lever or Vibratory bar '7 having one end playing in a slot 8 in' a guide bar 9 forming a part of a supplemental frame which may be erected at any convenient point, being shown within a power vhouse 10. A clip or bracket 11 is pivoted to the lever or Vibratory bar 7 and is preferably a fork on the end of a connecting rod 12 which is attached to a bell-crank 13 mounted on the tower and connected to the plunger 5 to be actuated directly thereby. The driven shaft 14 is equipped with a fly-wheel or pulley 15 or a gear wheel may be substituted for the said pulley or fly-wheel, as will be readily understood. To the crank 16 of the shaft- 14, I pivotally attach the longer arm of an Speefication of Letters Patent.

angle leyer 17 which is piroted at its bend or angle to the lever 7, indicated at 18, and it will be understood that the connecting rod 12 may be attached to the bar 7 at either side of the pivot 18 and at greater or less distance therefrom according to 'the direction in which the crank 1G is to rotate and the length of the stroke thereof. To the extreniity of the shorter arm of the angle lever 17, I secure a resilient member which is fixed at its opposite end to the frame. In the illustrated form of the invention, twe Springs 19 and 20 are illustrated extending in opposite directions from the angle erer and secured to the supplemental frame 011 any other fixed support.

Tt is thought the operation of my improved device will be readily understood. The wind-wheel 2 and its 'shaft 3 are rotated by the wind in the usual manner so that the Crank Lidescribes its usual orbt and imparts a Vertical reciprocatory morement to the plunger 5. This movement of the plunger 5 will, of course, be transmitted through 'the bell-crank 13 and connecting rod 12 to the lerer or Vibratory bar T, and the pivot 18 of the angle lever 17 will, of course, be carried back and forth as the plunger and the lever 7 Vibrate. Assuming the parts to be in the position shown in l? 1, the windwheel and the fly-wheel, puiley, or gear wheel 15 are rotating in the direction indicated by the arrow respectirely adjacent thereto. As the crank 1G of the snaftlfli 'approaches a horizontal position, the longer arm of the lever 17 and the said crank will appr ach alinemcnt, as shown in Fig. 3, so that there will be a tendency of the crank to come to rest on the dead center and block the movement of the mechanism or else reverse the rotation ofthe crank shaft as the upper crank 4 starts upon its upward movement. This tendency, however, is overcome by the resilient connections between the angle lever and the support. As the angle lever travels with the vibratory bar 7 to the position shown in Fig. 8, the spring 19 is placed under tension, while the spring 20 is relaXed and the spring' 19 will reach its maximum tension just as the Crank 16 reaches the dead center point, whereupon the spring will overcome the load or friction between the angle lever and the crank and will pull upon the shorter arm of the angle lever, thereby causing the said lever to swing upon its pivotal connection with v move to the position shown in Fig. ai, crank 16 will tend to rest upon a dead center at the opposite side of the shaft 11k and the spring 20 will be put under tension, while the spring 19 will be relaxed, the result be-v ing that when the crank 1G reaches the dead center, the angle lever will be swung about its pivot point so that the crank 16 will be carried past the dead center and interruption to'the rotation of the crank shaft-let be avoided.

From the foregoing description, it will be seen that have provided an exceedingly simple mechanism, which may be readily mounted upon any windmill tower or connected withV any reciprocating prime inover so that the reciprocatory movement of the pit-man will be converted into rotary motion and any machinery continuousiy operated.

V/*hat I claim is w 1. The combination of a' driving crank shaft, a fixed support, a vibratory bar pivoted at one end to said support, connections between the driving shaft and said bar whereby the bar will be'vibrated, a driven crank shaft, a lever pivoted upon the vibratory bar and fitted at one end to the driven crank shaft to actuate the same, and resilient connections between the free end of the said lever and the fiXed support.

2. The combination of a driving crank shaft, a fixed support, a vibratory bar pivoted at its lower end to said support, devices connecting the driving shaft with said bar, a driven crank shaft, an angle lever pivoted at its angle upon the-said bar and having one'end fitted on the driven crank shaft, and a yieldable pressure device bearing `upon the free end of the angle lever.

3. The combination of a driving crank shaft, a fixed support, a vibratory bar pivoted at one end to said support, a driven crank shaft, means conne'c'ting the driving crank shaft with the vibratory bar, an angle lever pivoted at its angle upon the vibratory bar and connecting the driven crank shaft therewith, and springs mounted at opposite sides of the angle lever and attached to the free end of said lever. i

Li. The combination of a fixed support, a

guide thereon, a driving crank shaft, a vibratory bar fulcrumed at one 'end upon the support and having its free end playing in the said guide, means connecting the driving crankshaft with said bar, a driven crank shaft, an angle lever pivoted at its angle upon the vibratory bar and attached at one endV to the driven crank shaft, and springs secured to the fixed support at opposite sides of the angle lever and attached to the free end of said lever. i v V 5. The combination of a fixed support, a guidethereoin'a l-vibratory bar fulcrumed at one end on the support and having its opposite endiplaying freely in said guide, a driving shaft, a connecting rod actuatedby the driving shaft and adjustably secured to the vibratory bar, a driven crank shaft, i

an angle lever adjustably pivoted at its angle to the vibratory bar and having one arm connected to the driven crank shaft, and a yieldable pressure device acting on the free end of the other arm of the angle lever.

In testimony whereof I affiX my signature VVitnesses:
