MOTOR.

SPECIFICATION forming part of Letters Patent No. 509,052,.dated November 21, 1893.

Application filed March 13, 1893- such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in pump operating mechanism, and the object of the inventionis to improve the machine described in Letters Patent of the United States, No. 489,419, issued to me, bearing date January 3, 1893, and to this end the mechanism consists of the features, arrangements and combinations hereinafter described and claimed, all of` which will be fully understood by reference to the v accompanying drawings, in which is illustrated an Vembodiment thereof.

In the drawings, Figure lis a side elevation of the mechanism. Fig. 2 is a top or plan' view of the operating parts, the upper portions ofthe mechanism being removed. Fig. 8 is a plan View of the base of the machine, illustrating the pump cylinders and showing their connections with the central chamber. Fig. 4 is a top or plan view of the machine, the adjustable top frame being partly broken away. Fig. 5 is a fragmentary view in perspective of the movable spring actuated plate which returns the pivoted arm to itsupward limitofmovementaftereach downwardstrokel` Fig. 6 is a fragmentary view in perspective of one of the pivoted arms which operate the pumps.

Similar reference characters indicating corresponding parts or elements of the mechanism in the several views let the numeral 5 designate a stationary base supporting the pump cylinders 6, connected with the supply source by pipes 7 and provided with outlet conduits 8, leading to the central receiving chamber 9, provided with a discharge pipe 10 at the bottom. .The piston rod 12 of each lpump cylinder is movably connected at its sean no. 465,835. (No man.)

upper extremity with an arm 13 provided with 1acurved shank 13a that passes under the outer ous construction it is necessary to out away the material of the platforms rim, whereby lthe latter is greatly weakened, in order to .form suitable recesses for the reception of the arms attached to the pump pistons. By forming the arms curved, and passing them under the rim as in my present construction, I avoid vthe necessity of forming recesses inl the rim, since the free extremities of the arms are interiorly located with reference to the rims inner circumference. Hence the rim of the platform remains intact and at the same time laffords the support for the arms. The platform 1'4 is supported by legs or standards 16 connected with the base 5. Movably connect- 'ed with the outer extremity of arm 13, is arod vv17 forked at its lower extremity, as shown at -17a and secured to a vertically movable plate 18 apertured at each extremity as shown at 18, and carrying depending sleeves 18. The open'ings'in these sleeves coincide with the apertures in the plate which is supported by coil-springs 19 which are attached to the extremities of plate 18 outside of theguide rods 20 and to the platform 14 above. These guide rods pass through the apertures in plate 18 as well as the depending sleeves which give the plates an elongated bearing on the rods which are stationary and secured between lthe base 5 and the platform 14. Suitably secured to the top platform 14 and supported thereon, are the vertical rods 22, passingv through suitable apertures formed in the lugs 23 projecting exteriorlyfrom the rim 24, provided with radialarms 25a, and centrally guided and retained in place by the post 26 journaled upon platform 14. The rim 24 is IOO The function of the rim 24 and rollers 25 is to maintain the wheel 27 in operative relation with the disks 35hereinafter described.

Tere it not for said rim and its rollers, the cogged portion of the wheel 27 might under some circumstances slip from engagement with the peripheries of said disks, by virtue of theyielding quality of the metal compose ing the wheel which without the mechanism in question, would have only the post 26 to maintain itin operative relation with the disks. It is believed that the length of the wheels radius would be such that it would be unsafe to rely vupon the Wheels rigidity to maintain it at all times in engagement with the disks mentioned.

Thecogged periphery of wheel 27 is engaged by a pinion 29 made fast to the upper extremity of a vertical shaft 30 provided at its lower extremity with a bevel pinion 31, meshing with another similar pinion 32 made fast to a short horizontal shaft 33 journaled -in ya box 34 secured to the base 5.

Power is applied to the machine by rotat ing the shaft 33 which is provided with a pul- V ley 34a `which may be connected with any l inner portion of whoseface is smooth as shownj at 35c to make a proper bearing therefor.'

suitable motor.

Wheel 27 is supported from below by the disks 35 which are pivoted upon the periphery of a horizontal wheel 36 made fast to post 26 and rotating therewith. Disks 35 are of a ydiameter equal toi the distance between wheel 27 and the platform 14. The outer part of the face of disks 35 is cogged as shown at 35a to engage the correspondingly cogged` track 14aformed upon platform 14. The arms 13 lie in the path of the disks 35, the

Thesmooth portion of the disks'face does not engage the rim but projects over its inner circumference to engage the arms 13 which lie in their path. The outer face of rim 36 is also provided with smaller lrollers or disks 41 and 42 suitably pivoted on the rims. The rollers 35,41 and 42 are arranged on theirsupporting rim in setsfor groups, each 'set consisting of one roller of each kind. Of these rollers or rotating disks, 35 is the largest, 42 the smallest and 41 of an intermediate size. There are four sets of these roll-l upon each arm 13 during each rotation of the wheel36, whereby these arms are depressed so that they -lie in the same horizontal plane with the upper surface of platform 14, the

of the piston rods.

4piston'rods 12 being correspondingly depressed. The rim 36 is rotated in the direction indicated by the arrows in Fig. 2, whereby rollers 42, or the smallest rollers of each set engage and act upon the arms 13, first, giving them a partial downward movement, then follow the rollers`41 next in size which act to further depress the arms, after which f the disks 35 complete the downward movement of the armsand the corresponding stroke It will thus be seen that by reason of the cogged connection between thel disks 35 and the rim 36, the power 1s `much more efficiently and advantageously applied than when this connection is simply frictional asshown in my previousl patent.

The rods 17 and their plates 18 are alsosimultaneously and correspondin gl ydepressed, the springs19 being stretchedor placedaunder tension by the downward movement of` said plates. As soon asv the last roller-(35) of any set leaves the arm 13 the latter is immediately returned to its vupward limit of movement through the-medium ofrod 17 and plate 18' which is suddenly carried upward 'by the recoil of springs 19, to its original position ready for engagement by t-henext1setof rollers. Y

' It will thus be seen that my present construction is materially different-from that shown in Patent No. 489,419 and it is believed that important advantages are gained over the mechanism previously-patented, not-only from a standpoint ofsimplicity and economy of construction, but also in pointsofiefiiciency `and general utility.

Having thus described my invention, what I claim is 1. In a mechanical power, the combination of a suitable framework composed'of abase y,and an upper platform supported thereon, of one or more inclined arms,pivoted ontheupper platform atene extremityand supported by spring-actuated rods at the'other extremity, and a horizontally rotating wheel made 'fast to a vertical shaft j ournaled-in the framework and one or more Adisk-s pivoted on-the peripheryvof said wheel, the lface of these Vdisks being partly cogged and partly smooth,

the cogged portion engaging a cogged track formed kon the stationary platform, while the `smooth part engagesl the inclined arms which are Iforced downward against the upward tendency of the spring-actuated rods, which impartto the arms the -upward movement-as vsoon as the disks leave them, substantially as described.

2. In a mechanical power, the combination of a suitable frame-work having acircular cogged track, one or moreoscillatin'g arms `pivoted on the'frame-work, a horizontallyroers shown in the'drawings and each set acts tating wheel mounted on the `frame andcarrying one or more pivoted disks having a @Ogged face to engage the track on the frame',

` frame, a power wheel made fast to the shaft,

another wheel also made fast'to the shaft and carrying disks pivoted on its peripheryn'such disks having acoggedyface to engage tracks rformed on the power wheel and stationary' frame, and a plain face to engage the arms, substantially as described. 'l v 4. In a mechanicalpower, the combination of a suitable stationary frame-Work, oscillatingarms pivotedthereo'n and means for movingsaid arms in one direction, consisting of stationary rods, a plate slidingly supported thereon, coil-springs attached to the plate and to thel stationary platform, and another rod connected with the plate at one extremity,

and with t-he oscillating arm at the opposite extremity, substantially as'described.l

5 In a mechanical power,`the` combination of the stationary frame, the 'oscillating arms pivoted thereon, and means for imparting to said arms movement in one direction, consisting of a horizontally rotating wheel mounted on the frame-work, andV carrying a set of disks of dierent sizes pivotedpon the rim, and adapted to successively engage the arms, the largest of these rollers being pro vided with a cogged face to, engage a track formedon the frame, and a'plain face to engage the arms, substantially as described.

In testimony whereof I aftix my signature in presence of two witnesses.
