To all whom it may concern:

Be it known that I, FRANK M. ILER, of Rico,

l in the county of Dolores and State of Colorado,

have invented certain new and useful Improvements in Pumping Apparatus; and I do hereby declare the following to be a fu1l,'clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in mining-pumps, or mine-sinking pumps, the primary object being to construct pumping apparatus of the Character indicated, whereby there is no condensation of steam between the surface and bottom of the mine as with the steam-pumps heretofore used; wherein the buckets are actuated by ropes or' cables extending upthrough the shaft of the mine; that occupies less space than a steam-pump having the same capacity; whose wearing parts a're more quickly renewablej from which obstructions, that interfere with the operation of the pump, can be more readily removed and wherein'the means of attachment of the suction-hose is greatly simplified.

VVith this object in view, and to the end of realizing certain other advantages hereinafter detailed, my invention consists in certain features of construction, and in combinations of parts hereinafter described and poihted out in the claims.

In the accompanying drawings, Figure l is an elevation, mostly in central Vertical section, showing the barrels of the pump, heads of the same, dac. Fig. 2 is a central Vertical section showing, among other things, the lower portion of the delivery-pipe, the connection between the bucket-stems or rods and operating-cables, and the means employed whereby when one bucket is elevated or hoisted, the other bucketis positively lowered: Fig. 3 is a Vertical section on line 3-3, Fig. l. Fig. 4 is a transverse section on line 4-4, Fig. 2, looking downwardly. Fig. 5 is a transverse section on line 5-5, Fig. 1, looking downwardly. Fig. 6 is an elevation showing the Operating crankgshaft and the lever-mechanism, &c., operatively connecting the bucketactuating cables with said shaft. Fig. 7 is an enlarged'detail in -perspective hereinafter described. Fig.'S is an enlarged elevation, partly in section, of one of the buckets. Fig. 9 is a detail in perspective hereiuafter described. Fig. 10 is a plan in detail, partly in section', and Figs. 11 and 12 are details in perspective, all hereinaft-er described.

Referring to the drawings, A A represent the upright barrels of the pump, and B and C the upper and lower chambered heads of the barrels, respectively, the barrels having heads in common as shown in Fig. 1. The lower head O is in open relation with the suetion-hose D suitably connected with said head as hereinafter described. The upper head B communicates with delivery-pipe E (see Fig. 2) that is suitably connected with said head, preferably as hereinafter described, and extends to the surface above.V

Gdesignates the suction-valves of the pump; H the buckets, and I the bucket or deliveryvalves.

H' represents the bucket-stems or rods that extend upwardly through stuffrng-boxes J suitably attached to the upper head of the pump-barrels, and the bucket-rods or stems, at their upper ends, are connected, respectively, preferably by means of turn-buckles, H2, with ropes or cables, 1-13. that in turn are suitably connected (see Fig. 6) with bellcrank-levers, 1-14, fulcrumed, as at H5, to any 'suitable support on the surface above and operatively` connected with each other by means of a link or connecting-rod, H6, that in turn is operatively connected in any suitable manner with the' Operating machinery, for instance, as shown, with the crank, 1-17, of a crank-shaft, HB, to which power is applied in any manner. The two bell-cranks H4 are so arranged relative to each other that the two buckets of the pump are simultaneouslyactuated in opposite direetions, respectively. The means thus employed by me for hoisting and lowering the buckets is much simpler and cheaper and does not possess less efticiency than any means or mechanism heretofore employed for the purpose. Suitable means are provided whereby upon hoisting either one of the buckets the other bucket is positively lowered. Preferable means for the purpose is illustrated IOO member 1-19 of the one bncket-rod or stem, to which it is suitably attached, downwardly to and over a sheave or pulley K' suitably supported by the upper head of the pump-barrel, and thence retnrns and is suitably secured to the projecting-member 1-19 of the other bucket-stem or rod. By this construction, it will be observed that as either one of the buckets is elevated, the other bucket owing to the downward pull exerted by rope or cable K, upon its rod or stem, is positively lowered, said rope or cable, of course having length sntficient to accommodate the stroke of bucket-rods or stems.

The delivery-pipe E is connected with the upper head of the pump-barrel in any suitable manner. Head B is enlarged upwardly at its central portion, as at B', and the Chamber of said enlarged portion of the head, through which chamber passes the water or liquid pumped, is divided, at its central portion to accommodate the location of sheave K'. Portion B' of head B, at its upper end, is providedwith an external fiange B2, that is bolted to external fiange L' of the casing of a chamber L into which the lower section, e, of the delivery pipe extends. M designates a ring or collar that rests upon and is bolted, as at M', to the upper end of casing of chamber L, ring or collar M, at the top, being provided with an internal fiange, m, that is adapted to engage the top side of an external flange n of a ring N that is screw-threaded internally and mounted upon the correspondingly externally screw-threaded lower end of pipesection e', that constitutes the delivery-pipesection next above section e.

I would here remark that the delivery-pipe is usually composed of flanged sections of pipe, with the flanges at adjacent or contiguous ends of the pipe-Sections bolted together, and that the last section that is secured in place is section e'. Sometimes, however, upon the completion of the delivery-pipe,excepting the connection of said section e' with the pipe-section next above, it is found that the bolt-holes in the flange at the upper end of section e' do not register with the bolt-holes in the flange at the lower end of the pipe-section next above. Hence the importance of being able to turn pipe-section e' in order to bring the holes in the flange at the npperend of said pipe-section into registering relation with the holes in the flange at the lower end of the pipe-section next above. This is conveniently accomplished by the construction hereinbefore described, it being merely necessary to loosen bolts M' that secure ring or collar M, wherenpon pipe-section e' can be readily turned in the one direction or the other, to bring the same into the position required relative to the pipe-section next above.

The bucket-stemsor rods H' operate in suitable guide-ways O' formed by the opposing snrfaces of a pair of lngsO projectinglaterally from the adjacent side of the easing of cham tease? ber L, as shown very clearly in Figs. 4 and 9, and are held in the respective guide-ways, by means of a cap-plate O2, removably secured to the outer ends of lugs O in the following mannerz-The Cap-plate at or near each end is secured to the adjacent lug by means of an eye-bolt, O3. Both bolts O3 are pivoted within slots O4 of the respective lugs O (see Fig. O) and have nuts O5 mounted upon the screwthreaded shanks thereof at the outer side of the cap'plate. The cap-plate is slotted, as at O6, to enable the one bolt to be swung, upon loosening the nut thereon, out of engagement with the cap-plate as shown in dotted lines, Fig. 4, whereupon the other bolt with the capplate can be swung away from the respective bncket-rod or stem, as shown in dotted lines, same figure, to enable the removal of said rod or stem from the respective guide-ways. Each pair of lugs is located a suitable distance apart to accommodate between them the location and operation of rope or cable K.

The pump is supported in any suitable manner, preferably from timber, Q, in the mine-shaft. (See Fig. 3.) Preferable means for snpporting the pump from said timber is illustrated in Figs. 3 and 4, wherein the center portion B' of head B, at one side and at a suitable interval apart is provided with two laterally-projecting flanges or lugs B3 that, at their outer end, have secured thcreto a yoke R that connects and has bolted thereto two upright bars S. Each bat` S is embraced or engaged by a pair of clamping-jaws S' caused to tightly engage and clamp the respective bar by means of a bolt S? that extends through the pair of clamping-jaws, and the one clamping-jaw is provided with a tooth or spnr, S3, that engages the snpporting-timber. Supporting-timber Q may not be found at the same elevation in all mine-shafts. Hence elamping-jaws Sfare adjustable up and down said bars S, and the latter are quite long.

A feature of my invention of vast importance consists in the simple and convenient means employed for supporting the suetionhose or pipe from the lower head of the pump, and referring to Figs. 1, 3 and 5 that show the means referred to, the snction-hose-nipple cl is screwed into a sleeve, T, that, at its upper end engages a gasket, U, seated in an undercnt groove or recess C',in the lower end of head C. Sleeve T, in its lower end, is provided with an annular groove or recess, T', that is eugaged by the lower hooks V' of hook-ended upright-bars, V, that extend npwardly into holes or eavities C2, in laterally-projecting lugs C3 of head C, and terminate at their npper ends, in hooks, V2, that are engaged by wedges, VV, driven in undersaidhooks through lateral perforations O4 in lugs C3, the wedges at or near their rednced ends being provided, respectively, with a laterally-projecting lug or member XV' that serves as a stop to prevent the wedges from hacking out entirely in tease? loosening the .same -bywhich construction there is" no liabi'lity of the wedges becoming lost.

Joints X connect the barrels of the"pump With the respective heads of the pump. A gasket or packing X' is interposed between eachjoint X and the ends of the pump-barrels, said packing or gaskets being seated in underout annular grooves, X2, of the joints. A gasket or packing, X3, is interposed between each joint X and heads B and Cof the pump, packing or gaskets XS engaging undercut grooves X4 in said pump-heads. Suction- Valves G of the pump are preferably located within the lower joints X, being suitably seated preferably in the lower portion of said joints.

Heads B and C, pump-barrels and connecting-joints are held assembled by means of two bolts or rods, Y, located on opposite sides of the pump, respectively, and pivotally secured at their upper ends, as atlY', to laterally-projecting lugs or ears. Y4, of the upper head B. Said bolts or rods extend downwardly, respectively, through a slot in laterally-projecting lugs C5 of the lower head, said connecting-bolts or rods being secured in place by means of nuts Y2 mounted thereon below lugs C5 and preferably further secured by means of pins or cutters, Y, extending laterally through said lugs at the outer side of the rods or bolts. The pump-barrels are suitably hinged upon said rods orbolts Y in such a manner that by loosenin g bolts or rods Y, the parts will loosen or separate sufficiently to permit the pumpbarrels to be swung laterally upon said bolts or rods for repairs, cleaning or other purposes. A preferable hinge-connection of the lpump-barrels with aforesaid rods or bolts is shown in Fig. 1, wherein the barrels are provided, respectively, with a laterally projecting lug or ear a that preferably partially embraces 'the respective bolt or rod and rests upon a collar, a',,loosely mounted upon the bolt or rod, but held in place by means of a collar, ai, rigidly mounted upon therod or bolt preferably by means of a set-screw or bolt as, the hole a4 of lug or ear a engaging the upright pintle 0.5 of collar a'.

The pump-barrels have preferably an ear a at or near either end to render the barrels reversible so that in the assemblage of parts no particular care need be exercised as to which end'of the pump-barrel will come upper or lowermost. Screws or bolts a3 are of course .loosened preparatory to the afore-mentioned swinging aside of the pump-barrels. If desired, the headsof the pump may be tied to.- gether, centrally between the pump-barrels, by means of a tie-rod, T'r, but said rod should be made of two parts joined together by means of a turn-buckle or coupling as shown.

To prevent the upper joints X from dropping upon swinging the pump-barrels laterally, as hereinbefore indicated, said joints are provided, respectively, (see Fig. 3) with laterally-projecting 'lugs X5 provided with openended Vertical slots Xfor the passage of eyebolts X7, the eyes whereof are uppermost and engage the eyes of eye-bolts, X9, that are suitably secured to laterally-projecting lugs or ears b of head B. Upon loosening nuts X8 that are normally tightened against lugs X5, eye-bolts X7can'be swun g outwardl y, as shown in dotted lines, Fig. 3, to permit the removal of upper joints X as required in replaoing 01' renewing the packing at the ends of the joints or for other purposes.

An important feature concerning upper joints X consists in the downward taper of the internal wall of said joints, the latter, at the lower end, corresponding in diameter with the diameter of the pu mp-barrel, but having their diameter gradually increasing toward their upper end to facilitate the entrance of the buckets into the pump-barrels upon the assemblage of parts, more especially where elastic packing is used on the buckets.

The delivery-valves I are seated upon the buckets in the usual manner.

Another important feature of my invention consists in suitable means for expanding the packing of the buckets without necessitating the removal of the buckets from the pumpbarrel. Preferable means for the purpose is shown in Fig. 1, wherein one of the buckets is shown in section and whereinV I' designates the annular packing of the bucket, and in Figs. 7 and 8 wherein 12 designates an elastic split ring that engages the inner side of the packing. The edges of said ring, at the split in the ring are preferably V-shaped, (see Fig. 7) and engage corresponding grooves in the edges of a wedge, 13, that at its reduced end terminates in a screw-threaded shank 14 that has mounted thereon a nut, 15, engaging the lower end of the bucket. The bucket comprises, preferably, two spiders or perforated conical members 16, between the rims of which the packing is oonfined, the hubs of said spiders orconical members abutting each other and nicely mounted upon the lower end of the plunger-rod or stem, a butt-ring 17, preferably of steel, being interposed between a shoulder h on the bucket-rod or stem and the upper lmember 16 and engaging a recess in the hub of said member 16, the plunger-rod or stem being screw-threaded at its lower end and extending below the bucket where it has mounted thereon anut, h', that, in conjunction with shoulder h on the bucket-stem or rod, securely holds the parts of the bucket together. The upper end of wedge 13 is adapted to extend above split ring 12 and the rim of the upper spider or conical member of the bucket is recessed,as at 18, Fig. 8, to accommodate the location of said end of the wedge. The shank of the wedge extends through a hole l9 in the rim of the lower spider or conical member of the bucket and the wedge is operated by means of nut h' that, as already indicated, is mounted on the shank of the wedge below the bucket.

.By turning said nut in the one direction or the other the 'packing of the bucket is ex- IOC IIO

panded or coutracted as desired. Hence, it will be observed that when the packing becomes worn, it need not be renewed immediately, but is simply readjnsted by expanding the same and thereby maintaining the required engagement or fit of the packing with the internal wall of the respective barrel of the pump.

Nut h' is preferablyof the split variety, as shown more clearly in Fig. 10, and clamped upon the bucket-stem or rod by means of a bolt and nut, 712, by loosening which the splitnut can be quickly removed when required.

Referring again to t-he means employed for actnating the buckets, I Would remark that the Operating ropes or cables are not shown attached directly to the links that depend from the bell-cranks, but (see Fig.11) extend through half-clamp-boxes, Z, (one of which is shown detached in Fig. 12) that tightly clamp the ropes or cable between them, the internal surface of the half clamp-boxes being corrugated, grooved or otherwise formed, as at Z' Fig. 12, to conform to the extenal surface of the rope. The Operating cables should be of such length that they can readily be lengthened when required by separating or loosening the clamp-boxes and leaving out more rope or cable. The companion half-clamp-boxes are preferably clainped upon the respective rope or cable by means of bolts Z2 that extend through corresponding holes in the clampboxes and are suspended from the respective bell-cranklever H4 above by'means of links Z3.
