To all whom it may concern:
Be .it known that I, FRANCIS D. Tron, a
`citizen ofthe United States, and resident of Niantic, in the county of New London `and State of Connecticut, have invented certain new and useful Improvements in Pumps, of which the following is a speci yof a cycloidal or gyratory character.
While my invention is particularly adapted i for employment as a pump in which the gyratory motion of the piston is produced by a rotary motion of the shaft, 1t will be adapted for employment as an. engine, p ropelled by steam or gases or fluids, in which the gyratory motion ofthe piston will produce a rotary motion of the shaft.
The object of my invention is to reduce a mechanism of the class describe ,which will be extremely simple in construction, positive and effective in operation, and which will produce an enhanced or maxi mum degree of power with relation `to the units off operative force employed.
A further object of my improvements is to )rovide a `mechanism of the class de scri ed 'which will possess general advantages in point of simplicity, strength and durability, inexpensiveness in construction, minimum friction, economy, and eiiiciency.`
In the drawings- Figure 1 is a vertical transverse sectional view of the mechanism embodying my improvements.
Fig. 2 is a horizontal transverse sectional view thereof.
Fig. 3 is a verticalcross-section, taken on the line :1i-fm, Fig. 1.'
Fig. #L is aver-tical cross-section', taken on the line ,a-y, Fig. 1. l
Figs. 5, G, 7 and 8 are diagrammatic views, indicating different positions of the piston. Corresponding parts-in all the figures are denoted by the same reference characters.
lieten-ring to the drawings, 1 designates. the main body creasing of the mechanism, whch'isfmounted or fixed in any'suitable manner, preferably vertical (for4 instance, upon a'base portion- 2), and-is interiorly provided with an annular chamber, 3, which constitutes the cylinder. rl`he body or casing 1 may be constructed in a single piece,
comprising an end wall, 4, forming the closed side' of the annular cylinder-chamber 3, a side wall, 5, forming the outer annular wall' of ythe chamber 3, and a centrallyarranged interior wall,as at 6, projecting from the end wall 1 and forming the .inner annular wall of the chamber 3. Beyond the cylinder-chamber 3, the main casing 1 is provided with a chamber or interior space, 7, extending across the chamber Band Venlarged laterally with respect thereto, so that the full diameter of the chamber or'space 7 is greater than the full diameter of the cylinder-chamber 3, which clianfiber or space 7 accommodates the head-plate ,of the pis-I ton in its operative movement. Said chamber or space 7 may be formed by a flange extension or enlargement of the side wall 5 of the casing 1, projecting from the same circumferentially, as shown at 8. The outer side of the chamber or space 7 is^c1osed by a side wall, 9, oppositely located with relation to the end wall 4 of the casing 1, which wall S) may consist of a cheek-p1ate,'as shown, removably secured,.by lbolts, as at 11, to the face of the flange extension 8 which surrounds the chamber or s ace 7.
The cylinder-chamber 3 is divided by a fixed partition or head, 14, extending across the width of said chamber and preferably located at the top4 thereof. At one side ozt' said partition, and immediately adjacent thereto, is located the exhaust port, 15, which is constituted by an opening in the end wall 4 which forms the closed side of the cylinder-chamber, from which openingmaysuitably extend an exhaust pipe, as
shown'at 1G. At the opposite side of said partition 14, and immediately adjacent thereto, is located theinlet port, 17, which is constituted by an opening 1n the -end wall `4 which forms theclosed side of the cylhitler-chamber, corresponding to theexha ust opening l5, and from the inlet port 17 may suitably extend a feed-pipe, as shown at 18. The piston comprises a plate or head, 19, operative in the chamber or space 7 of the casing 1, having projecting from itsV inner face an annular or circularaiiange,20,
'operative within Vthe cylinder-chamber 3.
vbeyond whichtlange the peripheral portion of said head 'or plate 19 circumferentially extends, as at 2-1. The flange 20l1asii thickl ness"or Width area less'than thel' width area ofthe cylinder-chamber, and it is transversely recessed, as ut 22, to receive the lxed partition or head 14 in the chamber 25. Said recess is of 'u width uliproxiii'iateliI corresponding to the width of said partition, so tint the partition will approximately close the recess but o'sliding movement ofthe piston...flange 2O will bc permitted iipou und with relation' to the purtition in the operation of the piston.

"lhe purpose of this: sprinL mounting in the eeeentrie eonneetion between the slnift und the piston is 'to take up un) deiid-ceuter resistance at the instant of the initiul starting; of the rotary movement of the Shaft und to iiirilitate the operative action be- 'tween the Shaft and the piston.
i 'partition or head 14 macero Fromthe foregoingnescription, it Will be understood that the disk-piece or block 37 is eccentrically keyed upon the shaft 30 and operates eccentrically with relation to the piston, and that the shaft is thus eccentrically mounted with relation to the operation of the piston in the reverse gyratory movements of the latter within the cylinderchamber.
It Will be noted that the cheeklplate 9 operates to hold the piston to its seat and to yretain the disk-piece or block 37 in its eccentric mounting upon the shaft, and if desired a `suitable spring control `may be interposed with relation to this maintenance of the operative position of the piston and said block. Itivill be further noted that the exhaust and inlet ports 15--17 extend, in the preferred construction, across substantially -tlie `complete Width area of the cylinder-chamber 3.
The operation and-advantages of my i'nvention will be readily understood by those skilled in the art to which itappertains. The piston has an eccentric movement vvith relation to the 20 has a reverse gyratory movement in the cylinder-chamber and with relation to the as a fixed point, in
which movement the true center or axis of the piston with relation to the annular flange 2() describes a movement in a segs mental path With relation to the axis of the shaft. The relative construction and opera-tion is such that at all times in the movement of the piston the inner face, 28, of the piston-flange 20 contacts at some point with the inner wall 6 of the cylinder- .chamber 3 and the outer' face, 29, of said liange 20 contacts at some point with the outer wall 5 of the cylindenchamber. These contactsv `at all times during the movement of the piston cause the division, by the piston-flange 20, of' the cylinderchamber 3 into. two chambers, respectively operative as` inlet and exhaust chambers,
during the movement and operation of the,
plston.
Then the mechanism pump, the shaft `30 lis driven and rotated by any suitable source of-power and its eccentric 4bearing connection with the' piston causes the' operation of the latter in the reverse n gyratory movement whereby the water entering at the' inlet port 17 Will be discharged under pressure at the exhaust port 15. For an understanding of the operative movement and 'action of the piston, reference ,may be had to the diagrammatic illustrations' in `Figsl 5 to 8, inclusive. In Fig. 5, assuming the piston to be at its lowermost point of movement, the inner face 28 0f the flange 20 is 4bevil-ing against the inner wall 6 of the .cylinder-chamber 3 at the top and the outer face of said ange is hearing against the shaft and the 'piston-fiange is operative as a.
bottom, and the inlet and exhaust ports are respectively open to the respective spaces or outer wall of the cylinder-chamber at the chambers which then exist Within thecylin-` der-chamber, atopposite sides `of the parti# tion or head 14, between the pistonflange 20 and the outer wall chamber; now, as' the shaft 30 is revolved and.-.carries the piston toward the position shown in Fig. 6, the Water in the chamber (indicated at L) then at the righthand side of the partition 14 is driven by the piston flange 20, in its direction Within the cylindenehamber, out at the exhaust port, and the space or chamber at the left-hand side of the partition 14 enlarges and fills with water from. the inlet port. When the cylinder reaches the point shown in Fig. 6, the inner face 28 of the lane 20 is bearing avainst the inner Wall 6 of the cylinder-chamber 3 at the left-hand side andthe outer face 29 of said flange 4is bearing against the outer Wall 5 of the cylinder-chamber at the right-hand side, and in this `position water enters from the inlet )ort to thechamber (indicated at-M) then. eginningto form at the left-hand side of the partition 14 between the inner face 28 of the piston-flange 20and the inner wall 6 of the cylinder-chamber; now, as the piston continues, under action of the shaft, in the same direction of its eccentric movement until it reaches its uppermost position, as shown in Fig. the water in the chamber' L is entirely exhausted at the exhaust port, a successive chamber L is formed at the lower portion of the cylinder-chamber .between the outer face 29H01? the piston-flange 20 and the outer Wall of the cylinder-chamber, and the chamber M enlarges and fills from the inlet port. When the piston has reached its `ppermost position, as shown in Fig. 7, the outer face 29 of the Harige 2O is bearing against the outer Wall 5` of the cylinder-r chamber Sat the top and the inner face 28 of said flange, is bearing `again'sft"tlie inner Wall 6 of the cylinder-chamber at the bottom; the
5 of the cylindereccentric movement in one l lor continued `rotation of the shaft in its opel-af K tionof the piston then reverses the eccentric movement of the latter to a direction opposite to that it has described in moving from its lowermost to its uppermost Which reverse eccentric movement carries the piston toward the position shown in Fig. 8, and the Water in4 the chamber M is exhausted under pressure at the exhaust port. The reverse eccentric movement of the piston, as just described, Acontinues until the piston again reaches the lowermost "position, as shown in Figp, when the continued rotation of the shaft again starts the piston in an eccentric movement in a reverse direction as hereinabove described. 'It will be noted that,
during'the reverse eccentricmovements o'f position,
of the piston with relation to its annular flange 2O has described a complete movement in the path of a circle about the axis ofthe shaft, and that the piston has reciprocated up and down upon the fixed partition or head l-l at the top ofthe cylinder-chamber 3, the initial points of the respective reverse eccentric movements of the piston being when the latter isat its lowerniost position (shown in Fig. 5) and at its uppermost position (shown in Fig. 7). It will further be noted that-at all points iu the movement of' the piston and in the variable location ot' the respective chambers L and M into which the cylinder-chamber 3 is divided by the pistonlange'QO, water is always entering the cylinder-chamber 3 at the inlet port at one side of the fixed partition or head ll and being forced out at the exhaust port at the other side of said partition.
The extreme simplicity of the improved pump, under the construction constituting my invention as vherein described, is indicated by the .fact that the complete mechanism may consist in the main of but t'our parts, to wit: the body or casing l (in which is formed the cylinder-chamber 3), the piston, the shaft. 30, and the movable' wall torniing the cheek-plate 9,-which respective four parts may .be practically of4 integral construction.
1 do not desire to be understood as limiting myself to the detail construction and arrangement of parts as herein shown and described, as it is manifest that variations a'nd modifications therein may be resorted to, in the adaptation of my invention to varying conditions of use, without departing from the spirit and scope of my invention and im proveniente. I` therefore'reserve the right to all such variations andinodifications as properly fall within the scope of my invention and the terms of the followingclainis.
