'APPARATUS, FOR CONVERTING lVlOTlON.

SPECIFICATION forming part of Letters Patent No. 352,878, dated November 16, 1886. A

Application filed April 30, 1886.

To all whom it may concern.-

Be it known that we, JOHN FAYLOOMIs and BYRON EDWARD WING, of Shelby, in the county of Shelby and State of Iowa, have invented a new and useful Improvement in Apparatus for Converting Motion, of which the following is a specification.

Our invention consists in an improved apparatus for converting reciprocating into rotary motion, as will be hereinafter fully described, and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a perspectiveview of our improved apparatus, showing the same arranged in its operative position. Fig. 2 is a perspective dew tail view of one of the hollow flanged disks and the pawl-disk which rotates therein. Fig. 3 is a vertical longitudinal sectional view. Fig. 4 is a vertical sectional view; and Fig. 5 is-a detail View of the adjustable U shaped spring,

- hereinafter described.

The same letters of reference indicate corresponding parts in all the figures.

Referring to the several parts by letter, A represents the frame which supports in their operative positions the various portions of our improved apparatus. In'one end of this frame reciprocates between the vertical uprights B the vertical rack-bar O, which we have shown .rigidly secured to the lower end of the vertically-reciprocating rod D of a windmill, although it is obvious that the toothed racks E might besecured to the lower end of the rod D itself, if desired, without departing from the spirit of our invention.

J ournaled in what we shall denominate the inner end of the supporting-frame A are two parallel shafts, F F, the inner ends of which extend on each side of the rack-bar O, and on the inner portions of these shafts, but somewhat in advance of the rack-bar, are rigidly secured the disks G G, having each the thick annular flange H at its periphery, against the inner surface of which flange the pawls M bear when in operative position. Against the hollow inner face of these flanged disks G fit the pawl-disks I, which turn loosely on the. inner ends of the shafts F, each pawldisk having secured concentrically upon its outer face a pinion, J, which meshes with the teeth of the rack-bar C, while the inner face of each Serial No. 200,744.

ner, the wooden shoes Q, which we prefer to.

make of maple, and these maple shoes we pre- .fer to cover with astrip, R, of leather on their outer bearing-edge, although the leather may be dispensed with, if desired, as the maple shoe will work readily without it. The inner reduced end of each pawl is formed nearly circular, to adapt it'to fit and turn readily in the inner portion of the flaring recess L, the outer sides of the flaring recess being farther apart than the width of the neck of that end of the pawl, by which arrangement the pawl may turn slightly in the said recess, so as to bring its outer bearing edge into or out of contact with the inner surface of the annular flange H of its disk G, according to the direction in which its pawldisk I is being rotated by the rack-bar, the

flaring jaws of the recesses in the two pawl-;

disks on different sides of the rack-bar being inclined in opposite directions-on one disk to the right andon the other to the left-so that on the downs roke of the rack-bar the pawls of one disk will be thrown out into engagement with the flange of its disk, while on the upstroke of the rack-bar the pawls of the other disk (which on the previous movement were folded in out of engagement) will in turn be thrown out by the centrifugal action into contact with the annular flange of its.

disk G, by which arrangement the disks G G are alternately revolved by friction with the pawls,'one disk on the downstroke and the other on the upstroke of the rack-bar, both disks being thus revolved in the same direction. This arrangement of the recessesL and the pawls is clearly illustrated in Fig. 4 of the drawings.

To the outer end of each parallel shaft F is secured a gear-wheel, S, andthese two gearwheels mesh with a flangedpinion, T, secured onthe inner portion of a longitudinal shaft,

II, which carries at. its outer end the large balance drive'wheel V, aronndwhich passes belting to convey the rotary motion to any desired point.

It will be seen that by our improved apparatus a continuous revolution of the driveshaftis obtained, as the said shaft is rotated both on the up and down stroke of the rackbar, as previously described. By construct ing the pawls with the wooden bearing-shoes the pawls are prevented from wearing smooth and slipping on the inner face of the metal flange of the disks G, which would be liable to occur if a plain metal pawl were employed, and the leather strips R aid still further the gricifition between the pawls and the said flanged is s.

We construct the pumpingrod N of the windmill in two parts, W W, the adjacent ends of the said parts being connected together by the adjustable U shaped spring X, the ends of which are formed with the perforations Y Y, which admit of the spring being adjustably secured to the said ends or the rod so as to regulate its tension as desired. It will be seen that this springserves to takeup part of the motion when the windmill is running too fast, thereby equalizing the speed with which the lower portion of the rod V7, and therefore the rack-bar, is reciproeated, thereby causing the machinery of our improved apparatus for converting motion to run moreslnoothly and protecting it from sudden jars and strains, as

will be readily understood.

From the foregoing description, taken in connection with the accompanying drawings, the construction. operation. and advantages of ouriin proved apparatus for converting motion will be readily understood. The adjustable U-shapcd tension-spring X can be applied to any mill, as it may be moved in or out to regulateits tension as required. A con tinuous revolution of the drive-shaft and its band-wheel is secured, the said shaft being rotated on each movement of the pumping-rod of the windmill bothup and down, while by constructing our improved pawls with the wooden bearing-shoes the bearing-edges of which maybe covered with leather, all danger of the said pawls slipping and becoming inoperative is effectually obviated.

We propose to -file a separate application for theUshaped spring in combination with a pump rod or equivalent. Having thus described our invention, what we claim,and desire to secure by Letters Patent, is-

1. The combination, with the vertically-reciprocating rack bar, of ,the two parallel shafts having on their outer ends the gear wheels, and having rigidly secured upon them near their inner ends the hollow flangeddisks, the disks turning loosely onthe inner ends of the said shafts, having on their outer sides the concentric pinions which mesh with the said raclobar, and having on their inner sides the circular enlargements formed with the re cesses having the flaring mouths arranged as described, the metal pawls having the reduced inner-ends fitting and turning in the said recesses, and formed at their outer ends with the longitudinal recesses, the wooden shoes secured in the said recesses, and the drive-shaft having at its inner end the pinion and at its outer end the balance drive-wheel, all constructed and arranged to operate in the manner and for the purpose herein shown and set forth.

2. The combination,with the hollowflanged longitudinal recesses, the wooden shoes secured in the said recesses, and the leather strips secured around the bearing-edges of the said shoes, substantially as and for the purpose shown and described.

3. The combination, with the pumping rod of a windmill, consisting of the upper part and the lower part having at its lower end the rack-bar, ot' the adjustable U shaped spring connecting the adjacent ends of the said parts together,the two parallel shafts having on their outer ends the gear-wheel and having rigidly secured npon them near their inner ends the hollow flanged disks, the disks turning loosely onthe inner ends of the said shafts,

having on theirouter sides the concentric pin ions which mesh with the said rack'bar, and having on their inner sides the circular enlargements formed with the recesses having the flaring mouths arranged as described, the metal pawls having the reduced inner ends fitting and turning in the said recesses, and formed at their outer ends with the longitudinal recesses, the wooden shoes secured in the saidrecesses, and the drive-shaft having atits inner end the pinion and at its outer end the balancedrive-wheel, all constructed and arranged as and for the purpose shown and described.
