.To all 107mm t may concer/1,;

Be it known that l, FRANK H. Garnciinr, a citizen of the United States, residing at Alexandria, in the county of Alexandria and State of Virginia, have invented certain new and useful Improvements in Steering Appa ratus; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates lo improvements in that class of steering apparatus in which the power is transmitted through a series of pulleys or sheaves and chains to the rudder-post; and the object of my invention is to iniprove the construction of such steering apparatus, render them more reliable and powerful, 1n uch easier to operate, and to prevent leakage around the rudder-post, as also to lessen the friction, and thereby facilitate the movement.`

rlhe invention consists in arranging around the rudder-post a packing or stuffing box to prevent the water from being forced up around said post, as is now ordinarily the case.

It also consists in placing in or against the deck a plate recessed for the recept-ion of 'friction-rollers, which bear against the rudderpost, and said plate may extend partly or entirely around the post and serve to lessen the friction thereof.

It also consists in pivoting the shaft of the steering-wheel in a hollow sleeve or box attached to the upper end ofthe rudder-post, so as to compensate for any movement of said post and shaft; andit further consists in the construction and arrangement of certain details, as will be more fully described hereinafter, and more speciieallypointed out in the claims, reference being had to the accompanying drawings and the letters of reference marked thereon.

Like letters indicate similar parts in the different gures of the drawings, in which- Figure l represents a side elevation of my improved steering apparatus, partly in sec' tion. Fig. 2 is an end elevation of the same. Fig. 3 is a top or plan view of the packing-receptacle for the rudder-post. Fig. 4 are detail views of the anti-friction collar or plate in plan and sections. Fig. 4f is a modification. Fig. 5 is a detail view, partly in section, of the suitable vessel, and has at its upper end apivoted swivel-box or bearing, n, for the shaft B of the steering-wheel C. The swivel-box is mounted in a yoke, e, having a swivel-pin, e', which is held in place by a nut, e, and this is in turn secured to the top of the rudder-post by means of a cap, e". The cap is secured by screws e", which are entered through a hole in the flanged part aof the yoke. The swivelbox is supported on the points of the screws a, and held in place by lock-nuts. The shaft B has on its inner end a sprocket-wheel, D, and is supported at that end in a standard or bearingc. Achain,d,passesoverthesprocketwheel and extends to the sheaves E E', loosely mounted on a transverse shaft, b, supported in uprights or brackets G. Ou the sides of the sheaves are secured or cast the spools or drums F F', having a right and left hand thread, fj", by which the chain H, which is secured yt0 them, is prevented from folding or doubling on itself. rIhe chain H extends around a sheave, l, secured to the rudder-post, and imparts motion to it when the steeringwheel is operated.

To ease and facilitate the movement of the rudder-post, a collar, K, provided with frietion-rollers 7c, is arranged in the upper deck. Thiscollar may extendA entirely around the post, although I prefer to form it of about one-third the length of the'eircle, as shown at Fig. 4, and provide it with two rollers only, as this gives the best results. This collar is placed on the side nearest tothe'trausverse shaft b and its sheaves and drums, asthe strain would be in that direction.

An arrow-head, o, indicates the position of the rudder.

At the lower end of the rudder-post, or on the lower deck,where said post passes through the ship, is secured a packing-receptacle, L, made, preferably, in sections, and bolted together by means of flanges m and bolts Z. It is secured to the deck by bolts or screws passing through lugs a, or a flange. A bisected gland, p, and a bisected ring, p', are tted into the receptacle, and are adj usted in place by eyebolts p to compress the packing r against move much easier.

the rudder-post. The eyebolts are attached to pins s, secured to the sides'ot the packingreceptacle L, `so that they are always ready for use.

Instead of a swivel-pin, as represented in Fig. 5, the pin may have a ball end and be tted in a socket to correspond therewith without departing from the spirit of :my in'- vention. The swivel-box may be provided with trunnions moving in journals on the yokeV instead of using the screws e". Ametal band, t, is placed around the rudder-post for the rollers to bear against.

A becking attachment,for holding the wheel in position, consists of a disk, u, having a series of slots or projections, c, secured to the shaft B, and with said slotsa dog, fw, attached to the stand c, engages, by which the wheel is held. The wheel and shaft, with the disk, is moved slightly forward or aft, and thus engages or releases it with the dog.

It will be readily-seen that by arranging the sheaves and chains with the threaded spools, as herein shown, the chain passing over them will be kept separate, and will not double on itself, and great power can be exerted on the rudder-post-by the different sizes of sheaves, sprocket-wheel. and spools. The stuffing-box around the rudder-post prevents Water passing around it and into the vessel, which, as is well known, often amounts t0 a large quantity, necessitating eXtra pumping out ot' the ship. By the rollers around the rudder post binding and friction is prevented, and it will The swivel-box on the end of the rudder-post compensates for the Working or movement of the vessel, and the entire steeringapparatus requires much less power than those now in ordinary use, and is not liable to get out of working order.

I am aware that, broadly, a stufting-box for rudder-posts, with apacking, is not new; also, that a swivel-bearing for the steering-wheel shaft is old; and, also, that a becking attach- 1. The combination, with a rudderpost, ot a bisected stuffing-box secured to the deck, around said post, for the reception of packing, lto prevent leakage, when these parts are constructed as shown, and substantially as specied.

2. In a steering apparatus, the combination of the rudder-post having a sheave, I, and chain H, with the sheaves E E', having right and left hand threaded spools F, to which the chain d is secured, and passes over a sprocketwheel, D, on the shaft B, all substantially as set forth. i l

In a steering apparatus having a rudderpost operated by sheaves, sprocket-wheel, and spools provided with right and left hand threads, and chains connected to them, in com bination with astuftng-box for packing around said post, a recessed collar, with friction-rollers, arranged in the upper deck, and a swivel-box for the steering-wheel shaft, all constructed and arranged as and for the purpose herein described. u
