STEAM AND HAND STEERING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 418,921, dated January '7, 1890.

Application filed June 10, 1889. Serial No. 318,795. (No model.)

To all whom it may concern.-

, Be it known that I, WALTER MILLER, a cit-izen of the United States, residing at Cleveland, county of Ouyahoga, and State of Ohio, have invented certain new and useful Improvements in Combined Steam and Hand Steering Engines; and I hereby declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in combined steam and hand steering engines, and is designed to provide compact, durable, and effective mechanism whereby the movements of the steering-drum may be controlled by the steering-wheel by the employment of either steam or hand power, as may be most convenient or desirable.

My invention consists in the employment of a vertical shaft directly connected with the steering-wheel to operate the engines which actuate the steering-drum, and in the employment of the same shaft to operate the steering-drum independently of the engines and solely by hand.

My invention also consists in the connectin g mechanism and combination and arrangement of parts shown in the accompanying drawings, described herein, and more specifically pointed out in the claims.

In the drawings, Figure 1 is a side elevation of my invention. Fig. 2 is an end elevation, and Fig. an enlarged elevation, with the working parts in central vertical section.

My mechanism consists, primarily, of a pair of twin engines A, working upon a horizontal shaft A, and supported upon a hollow vertical frame B at one end of a horizontal bedplate B, at the other end of which is a vertical frame 13 Thesevertical frames B and B are provided with horizontal shaft-bearings a and horizontal bearings c for the shaft 0 of the steering-drum O, which is supported between them. A pinion D upon the shaft A drives the gear-wheel C keyed upon the drum-shaft O. The pinion D is movably fixed upon the shaft A by means of a spline (Z and set-screw d. At "one end of the bed-plate I supported by means of the vertical bearingb upon the frame B? and pedestal-bearing b on the bed-plate B, is the vertical shaft E, which communicates with the steeringwheel F above deck by means of the bevel gears E and F. (Shown in dotted lines in the upper part of Fig. 1.) Steam is admitted into the engine-cylinders A by means of a pipe A connecting their steam-chests. A change-valve A is placed centrally over the steam-ports a? in this pipe, as shown in section in Fig. 3, and operated by means of the valve-stem a and bell-cranks a and a with the connectingrod a, mounted upon the top of the frames B and B The outer end of the bell-crank a is sleeved between collars upon the sleeve G, which is connected by a spline g to the vertical shaft E. The lower end of sleeve G is enlarged and internally screw-threaded at G to receive-the hunting-screw H on the loose sleeve H, which is supported'in bearing 1), and is provided with the clutch-dog h at its lower end, and the pinion H which meshes with the large gear (3 upon the drum-shaft O.

To operate the engine by steam, the steering-wheel F is turned to the right or left, according to the direction in which it is desired to run the engine, thus transferring movement through the gears F and E to the shaft E. The sleeve G, which is connected to the shaft E by the spline g, then turns and is caused to raise or lower on the shaft by means of the huntingscrew connecting the sleeves G and H, and moves the outer arm of the bell-crank a and, through the connecting-rod d ,bell-c1'ank a and valvestem ct, causes the valve A to uncover the steam-ports a and admit steam to the enginecylinders. The upward movement of the sleeve G is regulated by the collar c and the lower movement by the top of the screw H. The gear-wheel O upon the drum-shaft C, in revolving, turns the pinion-sleeve H in the reverse direction given the shaft E, and tends to restore the sleeve G and bell-crank a to its former position and close the valve A which it will do at once if left to itself; or the engines can be kept in motion by continuously turning the steering-wheel.

lVhen no great power is required, the engine may be disconnected from the drum C by loosening the set-screw d from the pinion D and removing it from engagement with the gear 0 Engagement may then be made between the shaft E and the drum 0 by means of the arrangement shown at the foot of the "shaft E, in whichI is a removable sleeve fixed upon the shaft E by means of the spline I and provided with a clutch-dog f at its upper end corresponding to the dog h on the lower end of the sleeve H. The lower end of the sleeve I is threaded, as at 2", and engages with the screw cap J, provided with the hand-wheel J and turning loosely upon the shaft E. Collars K and L retain it in position on the shaft.

When it is desired to work the drum 0 directly from the shaft E, the hand-wheel J is turned, bringing the two dogs 1' and h of the clutch together and transferring the movement of the shaft E to the shaft 0 by means of the gears II and C The pinion H being smaller than the gear 0 increases the power.

I do not claim as my invention the application of the change or floating valve to the steam-pipe, nor, broadly, the application of the steam-power to a steering apparatus, nor doI confine myself to any given proportion of parts or specific form of construction; but

What I claim as new, and desire to secure by Letters Patent, is

1. In a combined steam and hand steerer, a vertical shaft, as E, with detachable means for connecting the same with a steeringdrum, as C, a steering-wheel, as F, com municating with the upper portion of the shaft by bevel-gears, as E and F, and sleeve and differential thread, as G, communicating with the steering-valve by means of hellcranks, as a and a and rod a, substantially as and for the purpose set forth.

2.
