In operation the rotation of the gears 56 carries the gears 62 in an annular path, thereby rolling them around within the internal gears 60. Since the latter are twice the diameter of. the gears 62 the crank-pin66 moves through a diametral line of the in ternal gears 60 and verticallvwhen, as shown, the crank-pin 66 -and end journals 64- are in a vertical plane at theendof the 4 stroke. In practice one internal gear 60 and spur gear 62 in mesh therewith may beomit ted without detriment to the action, one pair or twobeing used as desired. Journaled upon the crank-pin is a bearing member 68 to which the upper end of the rod 16 and the lower, end of the rack 44 are attached so as to be in alinement with each other. The rod 16 and the rack 14 are, therefore, reciprocated in a straight line without hav: ing any lateral movement and the inwardlyfacing racks 17 are in order to secure a compact and rigid structure placed closely adac'ent on either side. The gear case or body has journaled therein pinions 74 meshing with the double rack as and also with the racks 417. Rollers 76, also journaled in the gear casing 38, engage the outer edges of the racks to support them for reciprocating movement.

'7 and 8 show a desirable construction for mounting the spur gears 62 on the double crank 1 so as to economize space and so as to term a rigid'construction. The cranlr 61 is preferably 'made of cast steel. The crank cheeks are formed of comparatively thin and large overlapping disks 82 and 78. the latter being concentric with the end bearings 64: 'llheportion of the cheek comprising the disk '78 lies within the gear 62 and adjacent the web 86 of the gear which it is sce d by bolts 9 shows desirable manner of a tachin the 1 gears 66 within the gear The rods are then be slid back out of pump rods and 18 alpump rods passing 86 at opposite sides, the internal gears being secured thereto by screw-bolts 88. Gaps in these flanges are left at the top and bottom so as not to interfere with the up-and-down movement of the crank.

Figs; 10, 11 and 12 show a construction by means of which the pump rods may be disconnected in order that the pump-head may he slid back out of the 'way. The cross-head to which the hollow rod 20 is attached is deflected upwardly to form arms 90 which in their uppermost positi on'extend above the base 36 and to which the rods {16 are attached; at the same time the bearing member 68 having the rod 16 attached to it by the nut 115 is in its lowest position and can be reached through the plate 116 in thecase. detached by unscrewing the nuts 115 and 117 and the pump-head can the way. A spider 92is supported by the base 36 and this spider has its transverse arms 94; spaced apart sufliciently to permit reciprocation of the cross-head; Rods 96 depending from the spider serve to support a discharge T 98 to which the top of the pump casing or drop pipe is secured and to which the discharge pipe 30 is connected. lnorder that the pump-head may have its rods in axial alinement with the drop pipe 12 when in operation, the spider 92 is leveled and alined up with it "and set-screws 118 bearing in sockets in the base 36 or other suitable means are provided to maintain the alinement.

. Figs. 10 and 11 show a lubricating'systern for'the pump-head. An oil reservoir 100 is connected by a pipe 102 with a small pump 104 driven by a pulley 106. This pump forces oil through a pipe 108 having branches 110 and 112 which deliver the oil to the bearings in the pump-head from which the oil drains back to the reservoir 100 through a pipe 1141 indicated in Fig. 11.

Fig. 13 shows a floating stuihng-box which may be used for the rods 16 or the'rod 16. A free stufling-box 119 provided with a recessed cover 126 has an enlarged flanged portion 121 adapted to move laterally between the casing 38 and a recessed retaining in said casing mounted in pairs and spaced apart, a crank pin connected to said planetary gear mechanism and extending across said space and reciprocable by the gear mechamsm in a straight line, a mnltiplicity of through said base and within the space in said casing, and means connected directly with said crank pin for operating all of said pump rods.

2. A pump comprising a base and a closed casing mounted thereon, planetary gear mechanism in said casing mounted in pairs and spaced apart, a crank pin connected to said planetary gear mechanism and extending across said space and reciprocable by the gear mechanism in a straight line, a multiplicity of pump rods, a corresponding num ber of stuffing boxes in said base. through which said pump rods extend to within the casing, and means connected directly with said crank pin for operating all of said pump rods.

3. A pump comprising a casing forming a chamber, planetary gear mounted in said chamber, a pump rod, means connecting said pum'p rod with'the gear mechanism for reciprocating the end of the rod back and forth across said chamber, a second pump rod having a pair of arms extending in parallel spaced relation relative to the first pump rod and mounted for movement back and forth across said chamber, and means for operating. said second pump rod from the first pump rod, substantially as described.

41. A pump comprising planetary gear mechanisms mounted inpairs amispaced apart, a crank pin connected to said plane- -tary gear mechanism and extending across said space and reciprocable thereby in a straight line,'a pump rod connected to said crank, a second pump rod having a pair of arms connected therewith movable in the plane of the first named pump rod on either side thereof and within the space between the sets of planetary gears, and means operated by the crank pin for actuating the pair of arms to reciprocate the second pump rod in opposite direction to that of the first pump rod, substantially as described.

6. A pump comprising a casing embodyupper and a lower chamber, a rotary member in the lower chamber, a pump rod having connection with said rotary member and reciprocated thereby back and forth across said lower chamber, a rack connected with the punip rod and reciprocated thereby back and forth across said lower chamber and'into the upper chamber, a second pump rod, and means connected with said second pump rod, and movable back and forth across said lower chamber and into the upper chamber, said connecting means being operated by the rack.
