SAND-REEL.

SPECIFICATION forming part of Lettefs Patent No. 455,530, dated July "1', 1891.

Applicationfded September 27, 1890. Serial No. 366,345. (No model.) r

The invention relates to improvements in sand-reels.

Heretofore great diflicnlty has been experienced in preserving the proper adjustment Y and contact between the large pulley receivv and their point of contact varies.

ing motion from an engine, and the small pulley-which is mounted on the windlass carrying the rope forl raising the rock, sediment, or grindings cnt by drilling wells. These pulleys are constructed of wood andform frictional gear, and great pressure is required to cause the pulleys to gear properly, and the wood ofthe pulleys becomes rapidly worn The object of the present invention is to provide 'means whereby the pulleys may be readily adjusted and maintained at their proper point of contact..

The-invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, an'd pointed out in the claims hereto appended.

VIn the drawings,'Figu1-e 1 isA a plan view showing the pulleys of a sand-reel adjusted in accordance with this invention. Fig. 2 is a side elevation of the same. Fig. 3 is a transverse sectional View. Figs. 4 and 5 are detail views.

" Referring tothe accompanying drawings,

ldesignates a large pulley constructed of wood and mounted upon .a shaft 2, having` its ends journaled in uprights 3, rising from sills 4 and 5. The pulley 1 is designed to receive motion by a belt from an engine or other suitable motive power and transmits such motion by frictional contact toa small pulley 6, mounted upon a windlassshaft 7, which is designed to carry the rope or cable for raising the ground stone from wells being drilled. One end of the windlass is journaled in a standard S, and the pulley 6'. is mounted uponv the shaft or windlass near its opposite end 9, whichvis journaled in a swinging lever 10, and the said windlassor shaft` is arranged at an bifurcation one end of a connecting rod or bar 11, which has its other end bifurcated and pivotally secured to an operatingslev'er 12. Thelower end of the swinging lever is provided with a transverse opening 13, through which passes a pivot 14, which Ais journaled in' bearing-openings 15 of longitudinally-adjustable bars 1G, which are adapted to change the fulcrum-point of the swinging lever l0 to facilitate the adjustment ofv the pulley 6. The lon gitudinally-adjustable bars -are provided with threaded ends l1'7, and are arranged in recesses formed by blocks 18, secured to the upperface of the sill 4, and the latter is provided with a recess 19 in its upper face -to receive the lower end of theswinging lever lO. The threaded ends of the a'dj ustahle bars are engaged by nuts which bear against the opposite ends of the blocks 18,- and the sill 4 is recessed at theends of these blocks to make the shoulders formed bythem lnore pronounced. By screwing the nuts 2O the bars can be moved longitudinally and the fulcrum-point of the swinging levercan be adjusted, as desired. The longitudinally-adj ustable bars are retained in the recesses 'by screws 21, which have vsquared heads to be readily'engaged by a wrench or similar' in'- strument, and are provided with collars 22, which have curved extensions 23 that yengage the said-bars.

The periphery of the snial'l'v pulley 6 is slightly beveled; and it will. be `seen that by the construction above described the pulley 6 can be readily adjusted relative to the pulley l and be maintained at ,the ,proper point of contact. i

' -What I claim'isl. The combination of the sill, the longitudinally-adjustable bars' mounted on the sill g and having threaded ends and .provided with ioo at its lower end with a transverse opening,

the pivotpassing through the bearings of the said bars and the opening of the swinging.

The combination of the ,sill 2, the longitudinally-adjustable bars having threaded ends and provided with bearing-openings, the
