Tofallwhom it'may co ncerh: I

Be it knownthat LP TER'J. F'AENING, a citizen of the United; States, resldlng at Providence, in the county of Providence and State of Rhode Island, have 'inventedg' certain new and useful Improvements-inPower; Mechanisms, ofwhich the follow ng 1s a specification.

My inventlon relates to such powermech anisms as engines, motors,'a ir compressors, blower and pumps; V g V 'The. essential objects of my invention are* to insure a tight contact of the disk, With the casing; to equalize the wear oni-the faces of the former; to obtain a continuous flow of the fluid, liquid,;.or air; tominimize the number of valves or entirely dispense there with, to avoid leakage of fluid, liquid, or

' air during'compression; and'to-attain these ends'in a structure which isinexpensiveand simple in construction and operation.

Further objects of my invention will appear from an examination'of the drawings.

and following description, I

Like reference characters indicate :like;

parts throughout the "views,

In the embodiment of the present anven 'tionthe, assemblage of parts may comprise in a general way a casing comprlsing'abase. 10, a cylindrical body or-ring 11 provided:

with annular flanges 12 to which are at tached by'screws 13, 14, heads orplates'll' and 18 respectively. The heads are respec-- tively provided with laterally extending ver-, ticallydisposed extensions 19Land 20 Q-in. alinement with each other andhaving par allel side walls 21, 21 and 22, 22. The respective extensions are completed byplates scope spectively- These extensions form; guide- Ways or, oblong chambers 27 and 28. The

parallelheads or Walls 17 and 18-;together with the rim or, body; 11 form asubstan-v 24L integral with'the extensions attached thereto by screws v2,5 and-26 re:

in corresponding walls 21 and 22 respectively, which o en in turnat .35and 36 at points in the outer ends of :the chambers 27 and 28 respectively, as shown :in Fig-5.-

The casing is completed by an integral en largementiorhea'd 38 upon the top of the body 11 pro videdlwith oppositely disposed} dorificesw and 40, in alinement with i C each other, in whichare threaded the ends of the intake or suction pipe -11 and thedis-d chargepipe 12 respectively. Passages 13- and 44 extend from. the ends of the respec-n tive pipes into passages 4L5 and ltiformed by transversely disposedyparallel grooves. traverslngthe inner face of the member 11, To the above recited; and suggested: ends, my invention consists in such parts and com-' and therefore openinginto the chamber 30.

tangular outline. ,Their "combined length being less than the combined length of the wings; itwillbenoted by reference to Fig.

3 that resultant spacesare formed at the '7. outerends ofthe chambers '27 and-28g and by reference to Fig. 5 it will; be further noted thatthe passages 33 and 34 open into' f sald spaces at 35 and-36 respectively};

The n f 'ends ofthe plates 7 and 48, at their upper portions,'have rectangular shouldersfor projecting ti aag and" 50, and immediately beneath these the adjacent edges of the plates: are transversely rounded, as at-51 and 52. Thefbottom edges of the, plates have channels "or iconcavities 53 and 54 to permit. an intimate registra-v tion withthe surface of the shaft. 56" of the This shaft isjournaled in the% lower portions of the wings 19 and 20, and. is concentric with the chamber BO-I'through. which it passes. -1 It projects through an.

machine;

opening 57 in the end plate 23 of the casing,

andhas fixed thereto the driving or driven Wheel 58 whichgin the present instance, is

driven from any'convenient source o-fpower.

The plate 47 is provided with an opening 59 having threads 60 extendingthroughthe 'ioo' shoulder; 49,. ThesplateSalso-has a. longi-i' in alinement with-the first mentioned open;-

ing or channel, extending through the shoulder 50, and opening at its outer end in vertical groove or channel 63 in the outer end. face of the. plate and. extending. midway thereof. A longitudinally disposed orifice 64 extends from the lower end of the channel 63. A. rod 66 has its end provided witha thread 67 to loosely engage the thread 60 of the opening 59, and extends through the channel 61. An arm 68 on this rod rests in the channel 63 and contacts with one end of a helical spring 7 0 seated in .the orifice 64. The upper "margins of the abutment? plates-47 and 18 are a sliding fit not only in the wings 19 and 20, but through a trans-' verse groove or guideway 71 in the head portion 38 of the b0dy 11 midway between the grooves 45 and 46 of the latter.

Integral with or brazed to thepower shaft 56 within the chamber 30 is a disk 72, Whose peripheral margin is inclinedto the axis of the shaft, and whose peripheral. face 73 is cylindrical and concentric with the shaft. The thickness of the disk wall is substantially the same throughout, and its side oroperating faces 7 5 and 7 6 meat every radial point at right angles to theaxis of the shaft. The right angular character of the radial points of the disk 72 are more clearly apparent in Fig.3, wherein the disk is shown in full sectional lines at an extreme of lateral travel; and in broken lines, its. position at the-end of its complete revolution. Hence byrotating the shaftthere is a lateral reciprocation in opposite directions to each other of those parts of the disk above and below the shaft; or an oscillation of the disk. 7 The disk op erating faces 75 and 76,as shown in Fig. 5,

are provided with the lateral convex swells or shoulders 79 and '80 respectively, upon opposite sides of the shaft, these swells being more pronounced adjacent. the shaft. Complementary of the swells are resultant lateral 'concavities 0r depressions 81 and 82 at those portions of the disk'directly opposite the respective swells.

The swells 7 9 and are preferably provided at their apices with slightly flattened surfaces 85 and 86,"

as shown in Fig. 1.

The disk in its rotation or oscillationtravels through the space 88 between the rounded edges 51 and 52 of the abutment plates, and in continuous contact therewith; the slight irregularities of thickness of the operative disk faces due to the fiat faces85 and 86, when such faces are present, being.

compensated for by-the spring 70 acting on the arm 68 androd 66 whereby the abutment members 47 and48 are pressed toward each other against the opposite surfaces'of thedisk.

The operation of the mechanism. in performing its functions asan air compressor.

in Figs. 1 and 5.- This rotation both :reciprocates the abutment and. sucks the air from its source of supply through the in? take port comprising the pipe 1.1,..passage. 44, andchannel 46 into one side of the'op-g eratingchamber '80... Simultaneously coin: pression is taking place inthe opposite side of said chamber whence the :air is expelled through-the outlet port comprising the chair. nel 45,- passage =43 and pipeAQ. Forrthe purpose of minimizing the number of views,

y the disk in Fig.53 isshownat its extreme lateral travelfan'd in Figr-5, at an inter I mediate position. In the latter figure it will be noted that the portion of the chamber 130, at oneside of the shaft 56 and= the abutment 51]and 52, is divided by the" disk,; whose peripheral surface is in slidable contactwith i t the wall 11, into two compartmen'tsST and 89, andthephalf'of the chamber 30 at .the

other side'ofj-the abutment;- into two air tight compartments-90 and 91. Participat ing in the boundary of theseacompartmei-its L "o are'the shoulders79" and 80,.which are'in'r continuous contact -with the side Walls of the casing during the rotation of the disk. The compression o-f-theair is wholly in the 1 compartments 90 and 91, andthe suction or vacuumis performed exclusively in tl18C0II1-1 partments 87 and .89. 1 v

It will be observed that in bothsets of compartments the. air is operated. upon by bothfaces-of thc:disk rather than upon one surface, a result not attainable by worms or spiral flanges. Communicationis constant between. the compression. compartments by"v the channel-45, and between the suction com! partments,=by the channel 4.6. To avoid the accidental escape of the air from the come. pression compartments intermediate the disk and the inner ends of'the partition plates 17' and 48,-and to avoidthe crampingiof these 2-:

members, communication is afforded from thecompartments-90 and 91, throughtheipassages 33 and 3 1, to the spaces 27 "and/28: at the ends of said members. Hencei thei degree of inwardpressure upon the outer r ends of the membersbalances-the pressure in the. compartments seeking escape. The; springthus performs its function effectively. and underno strain. The mechanism may-- be-operated with equal. facility by the use of: the parts 45, 4:3 and 42 asan inletport, and 'j the parts 11,4;4, and 46 as an outlet'port, in which case the direction ofrotation of the disk is reversed: 1 d

When the mechanism; is employed as an engine or motor. obviously the initial power. is not through theshaft 56, but-the fluid: under pressure enters through. one of the]: ports and exhausts through the other .port.

I have entered into a: detailed 'description' of the construction and relative arrangement 1 of the parts embraced in the present embodiment of my invention in order to impart a full, clear, and exact understanding of the 1 same. I do not desire, however, to be understood as confining myself to such specific construction and relative arrangement of parts, as such changes or modifications may an inclined disk in the chamber. upon the shaft provided with parallel side faces, and a partition comprising two plates'yieldingly' connected with each other slidably mounted in the casing with their adjacent ends in contact with the side faces of the disk.
