STEERINGEENGINE.

SPECIFICATION forming part of Letters Patent No. 528,356, dated October 30, 18 94. Application filed August 24, 1892. s rial No, 443,955. (No model.)

To all whom it may concern:

Be it known that I, MATTHIAS A. B K, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful improvements in Steering- Engines; and I do hereby declare that the: following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had tojth'ej accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. g

The main object of my invention is to provide for the operation of the steering appa ratus of tugs, yachts, torpedo or other boats by power or byhand or by both power and.

hand combined, with rapidity, ease and unfailing certainty. I

Itconsists essentially of the combination with a suitable drum or Windlass, of a motor and a steering wheel, either of which'may be connected at will with the Windlass so'asto actuate the same by power or by hand, or by power and hand combined; a break con trolled by the steering wheel, whereby the Windlass is held in any given position independently of the motor or pilot; certain peculiarities in the construction of the motor and its connections by which it is adaptedjto the purpose, and other noval features in'the. apparatus, hereinafter particularly described and pointed out in'the claims.

In the accompanying drawings like letters designate the sameparts in the several figures.

Figure 1 is a front elevation of' a steering, gear embodying my improvements. Fig.2- is a vertical section of the same on an enlarged scale, cutting the Windlass and steer ing. wheel axially. Fig. 3 is a side elevation. Fig. i is a horizontal section through the valve gear of the engine. Fig. 5 is a front elevation of a portion of the valve gear. Fig. 6 is a vertical cross section of the steering wheel shaft showinga portion of the reverse side of the steering wheel and the clutch mechanism for connecting the steering wheel withthe pinion loosely mounted upon its shaft; and Figs. 7 and 8 are detailed views, one being a front elevation and the other a side elevation of the automatic brake controlled by the steering wheel forholding the windlass in any given position independently of the engine and of the'pi lot.

. A represents the steering wheel, which may be of the usual well known form and'construction. It is fixed upon the front end of a hori- "zontal shafuB, which is supportedin suitable bearings b I), provided therefor in the upper part of the frame.

O is a chain wheel fixed upon/a shaft D, below and parallel with the shaftB, and supported at the ends in bearings d d, provided therefor in the frame. Upon the 'shaft D are mounted two gears E E, the first being keyed or otherwise fixed, and the other loosely mounted thereon. The chain wheel '0 may be formed with or mounted, as shown,

directly upon the hub of the fix'edgear E, with which it is designed to turn.

The tiller chain F running from opposite directions'to the steering gear,"passes underneath sheaves ff, thence upwardly over the chainwheel O, with which it engages and by which it is moved in either direction, in the usual manner; It is obvious that in place of D. They are providedat theirf'ront ends with crank wheels g g, and between their bearingswithpinions g, which engage with the loose gear E. on shaft D.- 1 For a inotor to actuate the Windlass, I employ atwin cylinder engine, the cylinders H H, valve chests I I and g'uides'J J of'which, may-be conveniently and are preferably cast integrally with the front side of the frame. K K are the piston rods of the engine, connected by rods is k with the crank pins of the wheels g g. L L are the valve rods, parallel with and located between the piston rods K K, with which they are connected by levers M'M, fulcrumedupon a stud'm, projecting from the front side of the frame, as shown in detail in Figs. 4. and 5. These levers cross each other, each connecting the valve rod on one side of the engine with the piston rod on thefopposite side. 4

i The are motion of the levers is provided for I by pivot blocks j j, inserted in slotted openings in their outer ends and mounted upon extensions of the pins jj', joining the connecting rods and the cross heads 7' of the piston rods, and by pivot blocks Z Z, mounted upon pins m m in the inner ends of said levers, and inserted in transverse slots in the upper ends of the valve rods. This form of valve gear, requiring little space, is particularly well adapted for the purpose, it being quite essential that the engine should occ-u py no greater space than is allowed in the pilot house for ordinary forms of steering gear. By keeping the engine within the limits of such a space, it can be readily placed in boats which have been equipped with the ordinary style of hand steering gear.

N is the reversing valve case, which is formed in connection with and adjacent to the main valve chests I I, with which it communicates through the ports 2' 2', as shown in Fig. 2, and with the exhaust chamber through the port 71'.

n is the reversing valve controlling the several ports mentioned and the admission of steam into and its exhaust from the main valve chests I I.

0 represents the steam supply pipe, provided with a valve 0, easily accessible to the pilot at the wheel, and 0 is the exhaust pipe.

P is a sleeve loosely mounted upon the steering wheel shaft B. It is formed or provided with a pinion p, engaging with the fixed .gear E, and with a nut 19' engaging with a screw thread on shaft B. The shaft B is restrained from endwise movement by collars b 6 on opposite sides of one of its bearings b, but the sleeve P is capable of a limited endwise as well as rotary movement thereon. The sleeve P is provided at its front end with extensible pins 19 and at its rear end with pins 19 adapted to engage with the ends of arc-shaped slots at a and h in the hub of the steering wheel and in the collar 1), when the steeringwheel is turned a certain distance in either direction, the pins 19 engaging the slots in the hub of the steering wheel when it is turned to the right, and the pins 13 engaging with the slots in collar b when the steering wheel is turned to the left.

It willbe understood of course, that the steering wheel A and the collar 1) are keyed or otherwise securely fastened upon the shaft B, and that the pins p p in the adjacent ends of sleeve P, constitute therewith, clutches for connecting and disconnecting the steering wheel and its shaft with said sleeve P and its pinion p.

Q is a bell cranked lever fulcrumed to the front side of the frame directly underneath the shaft B, and having its horizontal arm connected by a rod q with the stem of the reversing valve n. Its vertical arm is forked and engages a circumferential rib p on sleeve P. In this way the endwise movement of said sleeve produced by turning the thread on shaft B in either direction, operates to shift the reversing valve n. When the sleeve P is in its middle position upon the shaft B, as shown in Fig. 2, the valve n is also in its middle position, covering both the ports z t', and cutting 01f steam from both cylinders.

Referring to Figs. 7 and 8 in connect-ion with Figs. 1 and 2, R R are brake straps placed around the peripheries of the crank wheels 9 g, and bolted on one side thereof to the frame. 0n the inner sides of said wheels, adjacent to the lever Q, they are divided and the ends extended and perforated vertically in line with each other. Bolts 1', are inserted through these perforated ends and provided with springs 7", which tend to force the straps together against the peripheries of the crank wheels. Between the extended ends of the straps R R are placed cams or blocks S S, fixed on the ends of the pin .9, upon which the bell crank lever Q is fastened and fulcrumed. Whenever the lever Q is turned in either direction from the position in which it is shown in Fig. 2, the blocks or cams S are tilted, as indicated by dotted lines in Fig.8, thereby spreading the brake straps R and releasing the crank wheels g.

When the motor is employed to actuate the Windlass or chain wheel 0, the gear E with which the pinions on the crank shafts engage, is locked with the gear E by a spring latch e, as shown in Fig. 2. When however,it isdesired to disconnect the motor for any reason from the steering gear, the latch e is thrust back and held out of engagement with the gear E by passing a pin through aperforation or notch therein and a corresponding perforation in the web of gear E. For the purpose of disengaging the latch e from the gear E, a perforation e is formed in said gear, through which a pin or rod may be inserted by the pilot to force the latch back. For the purpose of rigidly connecting the steering wheel with the sleeve P and its pinion p, when it is desired to operate the steering gear in the ordinary manner through the steering wheel, the pinsp are made to be projected outwardly into engagement with sockets formed for their reception at the ends of the arc-shaped slots at, and they are provided with cross rods or pins 13 which project outwardly through slots in the sleeve P, in which they are held, as shown in Figs. 2, 3 and 6.

My improved steering gear operates as follows: lVhen the steering wheel A is turned in either direction, as for instance, to the right, the sleeve P is moved by the screw on shaft B endwise thereon,and acts through the bell crank lever Q, to spread the straps RR, and release the crank wheel, 9 g, and to shift the valve n, and thereby admit steam into the cylinders N N. Steam being admitted to the cylinders of the engine through the proper ports to turn the crank shafts G to the right, acts through the pinion g, gear E and the gear E with which it is connected, to turn the windlass or chain wheel 0 to the left. The gearE engaging with pinion p at the same time, turns the sleeve P to the right, thus tending to move it endwise upon the shaft B, back to its middle position, which it attains whenever the movement of the steering wheel A is arrested. As soon as the sleeve P comes to its middle position, as specified, the valve n is also brought to its middle position, and steam is thus cutoff from the cylinders of the engine and the movement of the chain wheel instantly stopped. At the same time the brake straps R are released and allowed to engage the peripheries of the crank wheels g, thus preventing their being turned in either direction until they are again released. The steering wheel A is permitted to turn approximately a quarter of a revolution in either direction before the ends of the arc-shaped slots in its hub or in the collar b will engage with the pins p or p in the ends of sleeve P, and when the engine is of sufficient power to perform the duty required of it, the movement of the steering wheel A in either direction will be almost instantly followed up by that of the engine in the corresponding direction, so that actual engagement of the clutch devices'on the steering wheel shaft B and sleeve P will not take place under ordinary conditions. In this way the engine, responding immediately to the movement of the steering wheel which controls the reversing valve n, turns the chain wheel 0 in either direction, exactly as it would be turned by the corresponding movement of the steering wheel.

If for any cause the engine should be unequal to the duty placed upon it, hand power will be automatically brought into requisition to assist it, because when the steering wheel is turned sufficiently in advance of the engine to cause the engagement of the pins 10 or p with the ends of the corresponding slots (1. or 12 the manual power of the pilot will be exerted through the pinion p and gear E to turn the chain wheel 0 in the same direction that the engine tends to turn it; or in case the engine should suddenly fail to perform its duty, the stearing gear would be actuated by the pilot through the steering wheel in the manner just explained.

In case it becomes desirable to disconnect the engine and to operate the steering gear by the steering wheel in the ordinary man-' ner, the latch e is moved and locked back out of engagement with the gear E, thus permitting the shaft D to turn freely in the gear E with which the crank shafts of the engine are connected, and the pins p p aredrawn forward by the cross rods p into engagement with the sockets at the ends of the slots a, in the hub of the steering wheel, thus readily connecting the steering wheel with the pinion 19 which engages with and under these conditions drives, the gear E. The brake straps R being automatically closed against the peripheries of the crank wheels whenever the reversing valve is closed, lock the steering gear in any given position in which it may be stopped and firmly hold the rudder in a corresponding position independently of the engine and steering wheel. In this way the rudder will not be displaced when struck by heavy seas which would otherwise move it out of position, their force being too great to be counteracted by the engine.

Various changes in the details of construction and arrangement of the steering gear as herein shown and described may be made within the spirit and intended scope of my invention.
