FLUID-OPERABLE MECHANISM.

To all 'u'hom it may concern 1 Be it known that we, REYNOLD JANNEY and HARVEY D. \VILLIAMS, citizensof the United States, residing at New .York and Wallingford, respectively, in the counties of New York and New Haven, States of New York and Connecticut, have invented certain new and useful Improvements in Fluid-Operable Mechanism, of which the following 'isa specification.

This invention relates to What we will for convenience term fluid-operable mechanism.

In various arts there are found an oscillatory member and connecting rods jointed to the oscillatory Inember'at opposite sides of the axis of oscillation thereof.

It is the primary'purpose of our invention to provide mechanism which is preferably fluid governed in character and is so related with the connecting rods as to operate them and simultaneously automatically compensate for changes in obliquity of said connecting rods.

. venient forms of embodiment of the invention which to enable those skilled in the art to practise the same Willbe set forth fully in the following description. We do not, however, restrict ourselves to this particular showing; we may depart therefrom in several respects within the scope of the inventioncovered by the claims following said description.

Referring to said drawings; Figure 1 is a top plan view of fluid-operable mechanism involving our invention. Fig. 2 is a side elevation of the same. Fig. 3 is a transverse section on the line33 of Fig. 2 looking in the direction of the arrow; Figs. 4 and5 are perspective views on enlarged scales of a yoke and a piston constituting parts of the mechanism.

Like characters refer to throughout the several figures.

As already noted mechanism involving our invention can be employed in widely' different fields; that is to say, the oscillatory member to which We have referred may subserve any desired function. Such an'oscillatory member as suits our conditions, is that Specification of Letters Patent.

denoted in a general way by 2, and it will be assumed that said oscillatory member" is a rudder head which after the usual fashion may be rigidly connected with the post 3. Pivoted or otherwise suitably connected with the oscillatory member 2 at opposite sides of its axis ofmotion are the connecting rods 4 and 5, the points of connection of these rods or links 4 and 5 with the oscillatory member 2 being preferably at equal distances from said axis. The two rods are connected at their forward ends as will heremafter appear, with elements which move in straight pathsand these elements form part of a floating fluid-operable mechanism which s of such nature thatwhen either connecting rod lS\ imparted a thrust, a pull of exactly equal extent is giventhe other by said mechanism.

As shown'the rod or link 4 is pivoted as .at at its forward end in the slot 7 of the -lug8 pro ecting laterally from the piston 9, the terminal portions of which reciprocate in the duplicate cylinders 10 and I1 mounted for bodily reciprocatory move ment in the

pillow blocks

12 and 13 rising from the base or bed 1 1. The two cylinders 10 and 11 as shown are cqnnected by the yoke 15 and also by-the tie rods or bolts 16 which extend, through abutting flanges on the yoke, and cylinders respectively. The

lug 8 to which we have'referred, extends through the opening 17'of, the yoke 15 or the part 15 might be considered as a tube having an opening in one side through which said lug or projection 8 extends. 'The yoke 15 on the side thereof opposite that having the slot or opening 17 is furnished with an outward projection 18 slotted to receive the forward end of the connecting rod 5 pivoted to said projection 18 as by the pivot 19. The reciprocatory. mounting of the two cylinders and piston with the rods connected -with the cylinder and piston mechanisms respectively compensates for variations in obliquity of the two connecting rods or links as they are oscillated and not only is'this so but the pull applied to either rod exactly equals the thrust exerted on the other. The two projections and lugs 8 and l8 have a bearing upon the base or bed 14, the latter having parallel ways or ribs 20 flat on their upper sides to receive the correspondingly flattened surfaces on y the under side of the two lugs or projections 8 and 18. The piston 9 also has a bearing engagement against the connecting yoke 15, the two parts having flat engaging surfaces 21 for such purpose. It, therefore, follows that as the 'two coaxial cylinders and the piston move backward and forward, there is no possibility of their turning. This, of course, is merely one of severaladvantageous ways of preventing rocking or move ment of the two cylinders and their cooperative piston about their longitudinal axes.

The power for reciprocating the piston 9 may be supplied in any desirable manner,

for instance by the hydraulic variable pump 22 which may be constructed exactly like the pump or so-called A-end of .the yariable, speed gearshown in I Aetters Patent N Q 924,787 granted to Bfnold J anney,-June ,15, 1909, and to whieit'referepce may be,had. This pump operating motor as 23 may be edfiir-any desirable manner. As shown'the pump and its motor-0f electric type, are both rigidly mounted on the yoke 15, but this as will be inferred, is not a matter of necessity. 1 After the usual fashion the electric motor 23 is coupled to the shaft of the hydraulic pu mpf2 2, the latter being provided with a regulator such as the well-known tilting box operable by the shaft 24 which can be actuated directly by' hand, by power or otherwise From the pump the

pipes

25 and 26 extend, the pipe 25- being connected with the cylinder 10, hile the pipe 26 is connected with the cylinder 11. The two pipes are intersected by a safety valve 27 of ordinary kind and which also acts as a by-passafter the usual fashion. Through theoperation of the control shaft 24, fluid can edirected in alternation into the cylinders 11 a d 12 so as to effect the relative operation 0 the piston 9 and connected cylinders lOand 11 and thereby apply a thrust to one of the two connecting rodsl and 5 and a pullon the other in accordance with the cylinders 10 and 11 into which the liquid is initially pumped by the pump 22. What we claim is:

1. The combination of piston mechanism and cylinder mechanism both mounted for relative reciprocatory movement, an oscillatory member, rods connected with the oscillatory member at opposite sides of its center of motion, one rod being connected with the piston mechanism and the other with the cylinder mechanism, and means for relatively operating the piston and cylinder mechanisms.
