To all whom/2'# may concern: v

.Be it known `thatfI, REYNo'LD JANNEY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new yand useful Improvements in Controlling Apparatus for Fluid-Gears, of which 'the following is a specification..

enablethose skilledin the art to practice the same will be set forth fully inthe following description, whilethevnovelty ofthe invention will be included in the claimszsucceeding said description. From this observation it Awill be evident that I dopnot restrict myself to such disclosure; Imaydepartttherefrom in many respects-within the scope of the invention included in the claims followi ing said description.

Referring to said drawings: 5 v Figure l is a side elevation of controlling with a hydraulic speed gear device of familiar type.

tion. It may, as illustrated, although this 1s not essential, consist of what isknown in hydraulic variablespeed gear `devices as a tiltin box. A hydraulic variable speed gear vsection or end, and athydraulic-engine secevice ordinarily comprises a pump tion or end, andit has been the practice to relate these two sections or ends in a great many different ways -which it isneedless for me to describe v as my` invention does not concernthese. In Fig- 1 of the drawings, however, I have represented one hydraulic variable speed gear device of known kind, the same being substantially similar to that shown in Letters Patent No. granted to me June-.15, 1909, andf towhich reference may be had. In said Fig.. 1 the numeral 5 denotes the pump end or section of the device while the numeral 6 represents the hydraulic engineend or motor section. thereof, and while asalready indicated it is i usual to arrange these portions in many dif# ferent ways, they are as illustrated coaxial, their-shells or cases abutting against the intermediate valve or mid'plate 7 andv the severalparts being bolted or otherwise suitablyconnected to each other. The `casing or shell of the pump end orv section 5 incloses a tilting box 'as 8, the oscillation or vrocking of which is utilized to vary or apparatus ,involving my invention and Y Vshowing the same operatively associated change the stroke of the pump pistons in 'the pump. end or Section5 to thereby correspondingly vvary the speed of or to` reverse vthe pistons in the hydraulic engine end or 'section 6. The tilting box 8, therefore, presents a regulatorv for anengine or motor, it

and through the latter, the engine or motor.

While as shown this regulatoris` adapted`l to effect changes in speed or direction of motion, these may not in all'cases be essenports-a vrotary shaft 9,.which is general y continuously driven and for this purpose any/desirable means may be provided, for

' which I have already alluded. It will be obvious that my invention does not reside 1n SllCh a device but rather in controlling primarily regulating the'pumporpumps,

means therefor, although as'I state this controlling means may be employed in other l ways.

I Will noW before doing so I Wish to make it clear that I do not restrict myself to such showing.

A control shaft housing as 11 is supported by/and in communication with the case or shell of the pump end 5 and in it Ahas screwed or otherwise fitted into it the control-shaft hanger-piece 12. I have shown as connected with said hanger piece 12, the bearing piece 13 and the lock nut 14 which with the several parts-associated therewith, constitute a` stuiiing box through which the control shaft 15 extends, said shaft being sustained by the hanger and bearing pieces to which I havejust referred. Said control shaft 15 Virtue of which endwise movement of thel control shaft 15 is prevented. As will hereinafter appear, this control shaft is operatively connected vwith the tilting box 8 in such .way that when the shaft is rotated the tilting box will be swung to either vary the stroke'of the pistons inv the pump end or to reverse the sameand such an operative connection as Will be understood can be' obi tained in many different Ways. It is equally conceivable that `the control shaft in some cases might not actually be in the form strictly speaking, of a shaft and therefore when I use the term control shaft it will be evident that I do so in a generic sense, intending thereby to cover various devices by Which the position of a tilting box or ysome analogous result can be effected to obtain the necessary action. The hanger piece 12 and its associated parts are: shown connected with one end of the control shaft housing 11, while in the other end thereof is represented as fitted a bearing piece 18 -provided with a stufling box 19 through which a compensating sleeve as 20 hereinafter more particularly described, extends. The housing 11 has a threaded opening 21 to receive the oil-expansion box 22 which is common in this type of apparatus.

The control shaft 15 may be operated in any suitable manner, although it is my custom to operate the same by hand, the force of which may be applied there-to either directly .or indirectly as shown. wheel 23 for instance maybe .utilized for this purpose, said hand Wheel being rigidly connected with the shaft 24, the housing 11 having an arm 25 to support said shaft 24. The effect of the manually-operable shaft 24 may be applied to the control shaftV describe in detail acontrolling mechanism which isf quite satisfactory, but

The hand i gearing, the gearing shown f r this purpose being of bevel type. Keye or otherwise suitably fastened to said shaft 24 is a bevel gear 26 in mesh with the bevel gear 27 keyed or otherwise suitably connected with the control shaft 15. \Vhen, therefore, the hand wheel 23 is rotated the control shaft 15 through the intermediate connections, will be also similarly rotated whereby the tilting box 8 will be oscillated.

The control shaft 15, as will be understood, extends through the bearing piece 1 3 and the hanger piece 12 into the control shaft housing 11, the inner end of said shaftbeing shown as threaded to fit threads in the compensating sleeve 20 to which I have already briefly referred, said compensating sleeve projecting from the casing through the bearing piece 18. The threaded or feed connection between the compensating sleeve 20 and the control shaft 15 is as illustrated, within the control shaft housing 11. The threaded or nut portion of the compensating sleeve 2 0 is represented as provided exte riorly thereof with an annular collar 28 which may be integral therewith, and also with lock nuts 29 and 30 threaded there? ontothe trunnioned sleeve 31 being held between said collar 28 and lock nuts 29 and 30. The compensating sleeve 20 maybe ro tated in the trunnioned sleeve 31 by mea'ns hereinafter described, and on this motion said trunnioned sleeve, as .will be apparent,

will be moved longitudinally of the controll shaft 15. The oppositely-disposedl trunnions-32 of the sleeve 31 have freely fitted to them, guide blocks 33 which as shown relatively slide between the fingers of the tilting box extension 34, said extension 3l being usually made as a yoke and the branches rthereof being slotted or forked to present when the same is rota-ted as already described, to effect the change in stroke of the pistons in the pump end orto reverse the movement of such pistons.

The tilting box is adapted to occupy a neutral, zero or iueective position as shown in Fig. 2, and when in this position the pist-ons in the pump end and in the engine end are at a state of rest. As the tilting box 8 is vswung from this neutral or zero position to an engine-starting or effective position, the pistons at the pump 'end 5 will be reciprocated thereby reciprocating the pistons in l the engme or motor end 6, the striikes of the shaft 15 to shift the tilting box into piston'- reciprocating position, and in thel present case this opposing effect is virtually continuous, although not essentially, and while it can be'accomplishedin different ways automatically by the power of the device, it is advantageously secured through the agency or aid. of the compensating sleeve2() as will hereinafter appear. Y

T he compensating-sleeve 20 has interiorly thereof the polygonal portion 37 to receive the polygonal portion 38 of-the shaft 39 .Y

supported for rotation by the arm 40 on the casing or shell of the engine section 6, and

. both polygonal portions are shownas square,

by reason of which when the shaft 38 is turned the compensating sleeve 20 will be correspondingly operated. The shaft 39 is what might be considered a power engine,

operated shaft, being continuously rotative or rotated as long as the engine 6 is in action, and this result may be secured for example by operatively connecting the shaft 39 with the shafty l0 for instance by gearing, said shaft 39 being shown as equipped with a spur gear 41 in mesh with a pinion 42 rigid with vthe shaft 10. The gear 41 and the collar 43 on the shaft 39 jointly prevent said shaft 39 from moving in an endwise direction or longitudinally.` While the inner end of the shaft 38 is in proximity to the inner end of the control shaft/15, these two shafts have no direct connection, although they are .operatively connectedl or indirectly so through the compensating sleeve; 41t will-be understood that the instant the control shaft 15 is operated to shift the tilting box 8 from its neutral or zero position, opposing means is automatically thrown into action and which tends to return said tilting boxl to said neutral position. With this preliminary statement, I will describe briefly the actin of the apparatus and certainV points connected therewith. When the control shaft 15 is operated, the compensating sleeve 20 owing to its described' connection with said shaft, will be moved longitudinally carrying with it the sleeve v31 and thereby tipping through a certain angle, the tilting box 8. As soon as said tilting box is thus operated the shaft 10 commences" to operate whereby the shaft 39( through the gearing referred ,to will be also rotated., The compensating sleeve 20fis also rotated by the'squared shaft 39. l might state atjthis time thatthe gearing between the shaft 10 and-the shaft 39 should preferably be such as to always cause said shaft 39 to rotate in the same direction as thel control shaft. It will loe understood that if the control shaft 15 be rotated in one direction to causeI the compensating sleeve 20 to move endwise, the rotation of the squared shaft 39 will be such as to cause said compensating sleeve to rotateV in such direction as to counteract the effect of the control shaft, the constant tendency being while the.

device is in action, to bring the compensating sleeve an'd necessarily the tilting box .back to a mid OrLneutral position ati/which -point the pistons of thepump end or section will not be reciprocated. 1f the control shaft 15 be turned rapidly so as to tilt or tip the tilting box into any desired position and be then .-stop'ped, the rotation of the shaft 10 will be such as to operate the 'squared' shaft 39 to bring as' already described, the tilting box to its neutral or zeroA position. 1n theory the time required for the compensating sleeve to f return toits neutral position-will be infinite, because as it ,approaches its neutral position the speed of the'shaft 10 becomes less and less Aand consequently the movement of the `compensating sleeve becomes slower Vand A slower. Practically, however, said compensating sleeve is returned to a point very near its neutral positlon quite rapidly and if the operator aids the movemet'b'y a slight reversal of rotation of the control shaft, saidr compensating sleeve will be brought to its zero or neutral position asl quickly as `de sired. f1f the operator rotatesl the control shaft 15 in either direction the action of the shaft 10 will be such as to cause the compensating sleeve to tend to counteract such rotation to overcome which it is necessary that the operator keep a little ahead of the com- I pensating action.- It follows, therefore, that the faster the operator rotates the control shaft the greater will be the degree of an: gular movement of the tilting box and hencethe greater will be the speed of the shaft 10. The mechanism therefore provides a means for controlling the speed of the shaft 10 or its equivalent by the rate at which the hand of the. operator'causes the control shaft to move and not simply by the angular position which hecauses the control shaft.

1n hydraulic transmission gear devices of the typehereinbefore referred to the speed and direction of movement of the shaft 10 from' which power is to be derived, are usually determined merely by the rotation of the control shaft to a limited degreel in one direction or the other, the angle of rotation of said control shaft determining positively the speed of the shaft l0 or some analogous point, depending generally on the rate of speed at which the `control shaft is turned and not on the angular distance throughV which it is turned. If, therefore, the control shaft be turned veryq rapidly through any angular distance, this angular distance will determine the maximum momentary speed of the shaft 10 which speed, however, rapidly falls toward zero through the action of the compensating sleeve in the manner already described. I might add in conclusion that the shaft 10 can operate various kinds of apparatus such as ships turrets, s, rudders, etc. It is also desirable `to add that I can continuously operate the con-l trol shaft or its equivalent in either direction at varying speeds according to the desired speed of said shaft l0, the latter at all times when in action tending constantly to counteract the effect on the tilting box or analogous member by 'the continuous rotation of said shaft; in other words there is a tendency of the engine f operated shaft' 10 constantly to catch up as 'it were with the control shaft when the same is being rotated manuallyor otherwise. I

The foregoing description applies particularly to the showing made by Figs. l to 3 inclusive. I have already intimated that I may use the controlling mechanism in various connections, and in Figs. 5 and 6 which will hereinafter be described in succession I sh`ow two forms of controlling mechanism different from each other and from the con- -struction already described fully. These equal advantage in connection with"`bther kinds of fluid governed or operated appara- -trol shaft being denoted b 44.

Atus or machines.

Referring now more particularly to Fig. 5; In this particular view the control shaft and counter control shaft are combined into one, said combined control andv counter co'n- What might be considered the contro end of said shaft is at the left, while the counter -con- 65.8 sleeve, said compensating member beingI trolling end thereof is at the right in said figure, although this is not at all essential. In the construction shown( by said 5, there is a; compensating member but st ictly speaking the same does not take the form of tion of said shaft is threaded as at.46, said threaded portion 46 extending through the gear 45 and engaging'corresponding threads within said gear. l.Thel controlling `portion of said. shaft 44 extends through the housing 11, the ends ofrwhich may be provided with stuiing boxes as 47 Land 48. Around the controlling portion of the shaft in the housing 11 is a trunnioned sleeve 49 conlars 50 and 51. The trunnioned sleeve 49 is connected with the tiltingl box 8 in the manner already described. The engine operated shaft 10 is equipped with a gear 42 as already described. This gear 42, however, is not connected directly with the gear 45 but is indirectly connected therewith through the intermediate gear 52, by reasonv of which the' gear 45 will be, rotated in the proper direction. The action of the construction shown in Fig. 5 briefly set forth is as fol-1 lows: When the shaft 44 is turned through the agency of the hand wheel 53 connected directly therewith or in some other suitable. way, said shaft is drawn endwise by virtue of its threaded connectionwith the gear 45 thereby moving the trunnioned hsleeve 49 therewith and giving to the tilting box 8 the necessary controlling movement. On the shifting of said tilting box the shaft 10 will, as will be understood, be rotated thereby through the described gears 42 and 52 rotating the gear 45. As said gear 45 is thus turned, the shaft 44 will be given a move` lment endwise to that when the shaft 44 is directly turned assuming "of course, that the lshaft 44 is notallowed to turn with the gear or wheel 41. The construction shownA in Fig. 5 provides a means for the ,continuous of the shaft 44as already explained, in connection with Figs. 1 to 3 inclusive.

Referring now to Fig. 6: In this organization the control shaft 54 extends through the housing 11 through stuiing boxes 42'v and 48. The control 'shaft 54, however, is separate fromthe counter controlling shaft 55, although the two shafts are operatively connected as will hereinafter appear. The

'control shaft 5,4 is threaded as at`56 to rebox 8 to its several controlling or' governing 130 positions. l might mention that part of the controlling shaft 56 which is within the threaded portion 60 extending through 'and being connected with threads within the gear 61 supported by the arm 40. The gear 61 like the gear 45, although rotary, is immovable in the direction of its axis of movement. The supporting arm is provided .with a key 62 to enter a longitudinally extending spline or keyway 63 in the counter controlling shaft to prevent vrotation of said shaft 55, although it is clear that the latter may be moved endwise. The tWo shafts 54 and 55 are connected together bythe coupling sleeve 64 and" the heads or flanges 65 and 66 at the ends of the respec- 'tive shafts'54 and 55 byv'reason of which the control shaft 54 can rotate independlently of the shaft 55, although the two musty move together endwise. In mesh with `the gear or `pinion 61 are teeth 67 cut at the upper end of the piston rod 68, ythe piston or plunger 69 of which is adapted to reciprocate; in the cylinder 70 or equivalent casing inlets for fluid opening into said cylinder or casing 70 at opposite sides of said piston 69 and being denoted by 71 and 72 l respectively. The ducts or inlets 71 and 72 are adapted for connection with any suitable fluid actuated apparatus such'for jexample as the pump sectionvof a device ofthe type already described. f

Briefly the operation of the construction shown inFig. 6 is as follows: By ,turning the control shaft 54 through the hand wheel 59, the nut 57 --will be noved along said shaft 54 thereby' to operate the tilting box 8. When this occurs fluid from the pump section will be caused to enter the casing or cylinder 70 by way of one or the other of the ducts 71 and 72 from the pump section to thereby operate the piston 69 and hence thepiston rod 68. When this occurs the gear 61 is rotatedand by reason of its feed connection with the ycounter control shaft 55,I said counter control shaft is moved endwise and'through the coupling sleeve 64 moving the control shaft 54 in a corresponding direction and consequently moving the nut 57 in a direction opposite to that it follows whenthe control shaft 54 is turned. l might mention lthat in the construction shown in Fig. 6 continuous rotation ofthe control-shaft54 is not provided for, the controlling eect, however, being secured by giving to the control shaft a definite number of turns. There isalso a fixed relation between the* amount 'f 'of ,movement of the piston 69 and the number of turns of theA control shafty 54. Arf. arrangement ofvthis kind is necessary where the greater part said piston is -to be moved `only a prescribed distance and then left for a 'time in its shifted position or returned to its original or anyother desired point. The speed of movement of the piston or equivalent part, however, is not, therefore, an important element to be considered. lt might also be 1. ln an apparatus of the class described,
