Like letters of referenceindicate correspon ding parts in all the figures.

My improved machine is of that class in which a brake-power is applied to the windlass to prevent the bucket running down too fast, by merely reversing the crank; and the invention consists in the construction, arrau gement, and combination of the parts connected with the crank and end of the windlass.

The parts are all mounted in asuitable curb, the windlass A having its bearings in supports B B, on opposite sides. At a suitable posit-ion outside the bearing, on the crank end, is secured rigidly to the shaft a circularshoulder, C, Figs. 2 and 3, having a plane face, a, against which a portion of the brake-friction is applied laterally, instead of vertically', as usual, as will presently be explained. The apparatus operating in connection with this shoulder consists of six principal parts-viz., a ratehetbox, D, a coiled spring, E, and adjusting gear-plate, G, a crank-gear, H, a coupling gear, T, and a pawl, K. These parts are constructed and arranged as follows: The ratchet-box D, Figs. 2, 3, and 4, consists of' a ratchet-disk, b, having a central hole for the passage of the shaft, (the back of the disk being made plano to bear against the shoulder 0,) and provided with ratchet-teeth c c, into which catches the pawl K, jointed to the support B, and, also, of a cylindrical flange, d, of

suitable diameter and projection to inclose the other parts. 0n the inside of this iiange are a suitable number of projecting ribs e e, or equivalents, the inner endsbeing made of greater width than the outer ones, so as to form, at the proper position, shoulders ff, for a purpose that will be directly explained. Within this box thus formed lits loosely the circular gear-plate G, Figs-3 and 6, with the spiral spring E intermediate to react against the plate. The edge of the gear-plate is pro-- vided with notches'g g, or equivalent, whose numberA and position correspond with the ribs e e, over which they slide, and whose size corresponds-with the'greatest width of said'rbS.

It is apparent that the arrangement ofthe notches g g and ribs e'e may be reversed-that is, the notches may be made' in the flange of the ratchet-bemand the ribs a lpart ofy the gear-plate, with the same effect. '.lhev outside of the gear-plate, or that side oppo'site'the spring, hasa number of concentric teeth'or ratches, h h, raised on its surface at lregular intervals apart, said teeth being' abrupt or right-angled at the forward end, and inclining down gradually in the rear, as shown in Fig. 6. This face of the plate is also provided with spaces or depressions t t', Fig. 3, situated between shoulders k k, Fig. 6, into which engage the projections of the coupling-gear,

as will presently beA described. The ,crank-v gear H, Figs. 3 and 7,'to which the operatinglevver l is secured, is-p'rovidcd with a short iiange, m, of similar diameter and shape to the iiange d of the ratchet-box, against which it abuts when in place. It is also provided with concentric raised teeth` a n, similar in shape, size, number, and position. with those of the gear-plate G, already described, except that they point in the opposite direction. When the parts are fitted together, the inclined teeth h h and n u gear or engage when the crank is turned forward, but ungear as it is turned back. Centrally through the crank-gear is a circular hole, through which passes the cylindrical end of the coupling-gear I, having projections o o, Fig. 8, which, when the crank is turning forward, engage with the depressions i l,above` described, as represented in Fig. 3. The` coupling-gear is .provided with -a plane shoulder or face, p, similar to the face c of the shoulder Q,- and for the same purpose-viz., to receive the brake-friction. The coupling-gear is secured rigidly to the shaft ofthe windlass by -means of a pin, q, or in some equivalent and ratchet-boxbeing` engaged byineans of the ribs and notches e g, thewhole are turned when the crankA is moved forward. .The parts 'are thusretained in engagement by the gearplate resting upon ther shoulders ff ot' the ribs e e, which prevent the said,V plate being forced inward, so as to release the parts. When the cra-nk is turned backward in the opposite direction, (the ratchet-box being held by -the pawlK,) the inclines of the teeth h n acting on' each other have a tendencyto sep.- arate the crankzgear and gear-plateV from each other. Y This action-turns the latter backward suihciently to release it from the shoulders f f ofthe ribs, allowing the notches g to fall over the wide-portion of the ribs, and the gearplate to be forced backwithin the ratchet-box suiciently to'disenga'geit from the prf'n'ec-l tions o o of the couplin ggear, when, of course, the crank is disengaged `froin thel shaft, and the windlass turns independently. v

The parts C and l beingrigidly secured to` the shaft, it is manifest that the saine action that expands the parts sufliciently' to freethe windlass will alsocause them to bear o n. the faces a- 11,7thus vproducing a lateral 'friction that can be varied to any degree desired.f

I am aware that a brake-powerhas before been applied to the windlass by the reverse action of the crank; but in, all devlces with which I am acquainted it is produced vertically, instead ot' horizontally or laterally, and the means of producing it are entirelyfdissini# ilai' to mine. By this .arrangement 1 obtain a larger frictional surface than -in any' other fdc vice, and thefictional contact is sustained the `whole distance around,'instead of lat only a certain point. My device, therefore, is more enduring and will longer resist-wear. Y

V'I prefer to use atilting bucket that 'has a valve in its bottom for admitting the water at thebottom of the well. i Iii ordinary buckets the bottom is made plane, `withthe valve set onthe same level. The valve admits much sand and dirt'with thewatcr, and when thus arranged this collects, so that the valve does not shut down closely, and the consequence isthat the bucket leaks, so as to be4 frequently inoperative. 'It also rots the leather and ren-y ders it worthless. I remedy this diiculty by ibriniug the bottoni of the bucket with its seat rforming a thin, plane edge on top, elevated above the general level of the floor, and hav# ling *inclined4 or vertical sides s extending downward, as represented. in Fig. l. This arrangement also forms the port t, of such a length as to give adirection or motion to the water that. enters, so'that it passes in with a current or positive action. 1n doing so it sweeps over the edge of the seat r, carrying i -,with it all sand or dirt that has gathered thereon, and keeping'it always clean, and the bucket always tight. The narrow edge vof thel valveseat allows the valve. to '.pack tightly upon it.

What I claim as my invention, and desire to secure by Letters Patent, is- Y l. Y The ratchet-box D, consisting of the disk b, havin g a laterallybearin g frictional surface,

the cylindrical ange d, and the ribs e e, or equivalent, said ratchet-box turning loosely on the shaft and held by the pawl. K, substantially as herein'descril'ied.

2. In combination with the ratchet boxthns arranged, the gear-plate Gr, having net-ches', i l g.V g, or equivalent, sliding over the ribs c c in speciiied.

3. In combination with the gearipla-t'e, pro- `vided with the concentric Vinclined teetlrh h,

the crank-gear II, having similar engaging teeth n n, substantially as and for the pur- ,pose herein set forth.4 t

4. In combination with the gear-'plate G and crankgear H, tliecoupling'gear I, ar-

ranged and operating substantiallyas herein speciled. Y

5 The combination and arran gement of the ratchet-benl), coiled spring E or equivalent, Vgear-plate G, crank-gear H, coupling-gear I, .pawl'K, and frictional bearing-shoulders a p', whereby the whole automatic` action is prolduced,substantially as herein set'fortli.

InV witness whereof I have'hereuntojsigned my name in the presence of two subscribing witnesses.- t
