POWER-TRANSMISSION MECHANISM.
Specification of Letters Patent.
Patented Oct. 3, 1905.
Application filed June 1,1905. Serial No. 263,303.
To (I/ZZ 1072/07)? it may concern:
Be it known that we, CHRISTIAN FoRTIIUN, residing at Oak Dale, in the county of Howard and State of Iowa, and MARTIN FoR'rI-IUN, residing at Leroy, in the county of Mower and State of Minnesota, citizens of the United States, have invented certain new and useful Improvements in Power-Transmission Mechanism; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Our invention has for its object to provide an improved power-transmission mechanism especially adapted to convert the reciprocating movement of a windmill pump-rod into continuous rotary motion for driving churns, corn-shellers, hay-cutters, feedmills, and various other machines used on farms and elsewhere. v
To the above ends the invention consists of the novel devices and combination of devices hereinafter described, and defined in the claim.
The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.
Figure 1 is a View in side elevation, with some parts broken away, showing our improved pwer-transmission mechanism. Fig. 2 is an elevation of the parts shown in Fig. 1 looking at the same at an angle of ninety degrees from direction from which it is viewed in Fig. 1, and Fig. 3 is a horizontal section taken on the line w v of Figs. 1 and 2 looking upward.
The numeral 1 indicates the vertical reciprocating pump-rod of the windmill, the other parts of which windmill are not shown.
The numeral 2 indicates a framework, shown as constructed of timbers.
The numeral 3 indicates a counter-shaft which is mounted in suitable bearings 4: on the framework 2 and is provided with a wide-faced ratchet-wheel 5 and with alarge spur-gear 6, both of which are secured thereto. The gear 6 meshes with a pinion 7, carried by a counter-shaft 8, journaled in suitable bearings 9 on the framework 2. This shaft 8 carries a pulley 10 and a fly-wheel 11.
Pivotally mounted on the shaft 3 and embracing the ratchet-wheel 5 is a pair of reversely-projecting levers 12, which are made up of a pair of plates rigidly secured by spacing-lugs 13 and bolts or rivets 14. Bolts 15 are also passed through the plates of the levers 12 near their outer portions. On each of these bolts 15 is pivotally mounted a pair of springpressed (:lriving-pawls 16, that engage with the teeth of the wide-faced ratchet-wheel 5. These pawls are thus arranged in pairs, the
members of a given pair being located side by side and one pawl of which pair is slightly longer than the other pawl, as best shown in Fig. 3, so that the amount of movement to engage one or the other of the pawls with the teeth of the wheel is thereby reduced. The outer portions of the pawl-carrying levers are connected to the pump-rod 1 by the depending links 17, the upper ends of which, as shown, are pronged and are directly pivoted to the projecting ends of the corresponding bolts 15.
\Vith the construction above described it is evident that under an upward movement of the pump-rod 1 the left-hand pawls 16 will engage the teeth of the ratcthet-wheel 5 and positively drive the said wheel, the shaft 3, and the gear 6 in the direction indicated by the arrow marked thereon in Fig. 1. It is also evident that under this upward movement of the pump-rod the right-hand pawls 16 will move upward, but will slip over the teeth of the ratchet-wheel 5 without impeding the rotation thereof. Under adownward movement of the pump-rod 1 the conditions will be reversed and the right-hand pawls 16 will become the drivers, while the left-hand pawls will slip freely over the teeth of the ratchetwheel. It will thus be seen that under the reciprocating movements of the pump-rod the pawls on the opposite sides of the ratchetwheel will be alternately thrown into action thereon to continuously and positively rotate said ratchet-wheel in a constant direction. lVith the multiplying-gear illustrated the shaft 8 will of course be driven at a much higher rate of speed than the shaft 3. By means of a belt (not shown, but which will be run over the pulley 10) power may be transmitted from the shaft 8 to the machine which is to be driven. I
The device described, while extremely s mple, is eflicient for the purposes had 1n view and will be found a very convenient device for use on farms, in dairies, and various other places.
What We claim, and desire to secure by Letters Patent of the United. States, is as follows:
The combination with a reciprocating rod 1, of a shaft 3, a Wide-faced ratchet-wheel on said shaft, a pair of bifurcated levers 12 pivoted on said shaft and em bracing said ratchet- Whecl, a pair of spring-pressed driving-pauls 16 pivoted to the outer portion of said levers l2 and engaging the teeth of said ratchet-Wheel 5, one member of each pair of pawls being longer than the other, and the links 17 pivotally connecting, the on tcr portion of said. levers 5 12 to the said reciprocating rod 1, substantially as described.
In testimony whereof We affix our signatures in presence of two witnesses.
