Application filed January 15,1906. Serial No. 296.130.
To all; 1071 0772 it um/y concern:
Be it known that I, EDWARD HANsoN B00- 0001(, a subject of the King of Great Britain, residing at est Vale, in the county of York, England, have invented certain new and useful Improvements in Steam and other Engines, Pumps, and the Like, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.
This invention relates particularly to pistons and piston-rods of reciprocating steamengines, but may be applied to similar gas or oil engines or to pumps or any other appliance or mechanism in which a reciprocating piston and piston-rod or the like is employed; and the object of the invention is to simplify the mechanism for giving the piston and piston-rod a rotary movement in addition to the usual reciprocating movement, also to employ a more effective means for securing the piston to the cross-head and for securing and adjusting the worm-wheel to and upon the piston-rod; and with these and other objects in view the invention consists in the construction, combination, and arrangement of the parts hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of our improvement are designated by suitable reference characters in each of the views, and in which-- Figure 1 is a plan of cross-head, showing piston and connecting-rod connections with my improvements applied. Fig. 2 is aside elevation of Fig. 1. Fig. 3 is a sectional side elevation of cross-head with my improvements applied. Fig. 4 is an end elevation of crosshead with my improvements applied. Fig. 5 is a sectional elevation of part of my im rovements, showing means for adjusting an fixing the position of the worm-wheel upon the piston-rod in case of wear. This method is especially suitable for powerful engines; and Fig. 6 is an end View of 5.
In order to accomplish the objects of this invention, I give a rotary motion to the piston and piston-rod in addition to and simultaneous with the ordinary reciprocating motion, the mechanism for which is actuated by the vertical oscillation of the connecting-rod of the engine.
In my invention I form the cross-head A with an arm B upon that side nearest the cylinder. This arm has a central hole C,
through which is passed the end of the pistonrod D, which is screwed or threaded at this part. Also, in addition to the hole aforesaid, there is provided an annular recess E upon each end of the said armB. In one recess fits the boss F of a worm-wheel G, keyed or other wise secured upon the piston-rod, and in the other its the boss II of a nut J. This nut J, screwing onto the end of the piston-rod D, secures the same to the cross-head A. Both the wheel G and nut J revolve with the piston-rod, and the recesses aforesaid serve as bearing-surfaces for both. The aforesaid arm B has also a projecting wing or bearing K, supporting a vertical shaft or stud L, upon which is a worm M, gearing with the worm wheel G aforesaid. At the other end of this stud L is secured a ratchet-wheel N, operated by a pawl P and lever B. This lever R pivots upon the boss S of the bearing K and is con nected by means of a link U, having a yokeshaped coupling T, with a similar coupling V, mounted upon the head WV of the connecting-rod X, attached to the cross-head A.
The action is as follows: The vertical oscillation of the connecting-rod X of engine gives a backward and forward movement to the link U and couplings T V aforesaid, operating the lever B and pawl P, which moves the ratchet-wheel N one tooth at each backward stroke of the eonneeting-rod X. The operation of the ratchet-wheel N gives a corresponding movement to the worm M and worm'wheel G, and the latter being fast upon the piston-rod D rotates the same and piston accordingly, the piston and rod making, preferably, one complete revolution for every two hundred revolutions of the crank-shaft, or this may be varied, as desired.
For large and powerful engines Where the bearing-surfaces of the worm-wheel and nut are liable to wear, and in order to compensate for such wear, I preferably secure the wormwheel G upon the piston-rod D by means of a toothed or serrated disk or clutch Y, (see Figs. 5 and 6,) said teeth Z of clutch engaging with a corresponding surface formed upon the side of the worm-wheel G. This clutch is secured to the worm-wheel G by bolts or setscrews 1 within radial slots 2 and upon op eration of the wheel G rotates the piston and piston-rod by means of key 3.
The adjustment in case of wear is effected by slackening the set-screws 1. The slots 2 enable the clutch to be turned, simultaneously moving the worm-wheel upon the thread of the piston-rod until its boss is in contact with its bearing-surface within the recess aforesaid. The set-screws are then tightened, clamping the clutch and worm-wheel together and the adjustment completed.
6 is a hole for lubricating the bearings.
For light engines the worm-wheel may be secured by cotter-pin 5. (See Figs. 1, 2, and 3.)
The catch 4 is provided in order to prevent oscillation or backward movement of the ratchet-wheel and shaft.
Having fully described my invention, what I claim as new, and desire to secure by Let ters Patent, is
1. In a steam-engine, a cross-head, a con necting-rod connected therewith, a pistonrod rotatably connected with the cross-head, a worm gear-wheel secured to the piston-rod, and devices operated by the cross-head and connecting-rod and'operating in connection with said worm gear-wheel for rotating the piston-rod, substantially as shown and described.
2. In a steam-engine, a cross-head, a connecting-rodponnected therewith, a pistonrod rotatably connected with the cross-head, a worm gear-wheel secured to the piston-rod, a worm supported adjacent to said gearwheel and meshing therewith, a ratchetwheel connected with said worm-gear, and devices operated by the cross-head and connecting-rod and operating in connection with said ratchet-wheel for turning said wormgear and rotating the piston-rod.
3. In a steam-engine, a cross-head provided with an arm having a central longiturod and dinalbore, a piston-rod one end of which passes through said bore, saidbore being provided at each end with an annular enlargement, a nut secured on the end of the pistonrovided with a boss which fits in one of said enlargements, a worm gear-wheel secured to the iston-rod and provided with a boss which ts in the other enlargement,
' and devices operated by the cross-head and connecting-rod and operating in connection with said worm gear-wheel for rotating the piston-rod.
4. In a steam-engine, a cross-head provided with an arm having a central bore provided at each end with an annular enlargement, a piston-rod which passes through said bore, a nut connected with one end of said rod and provided with a boss which fits in one of said annular enlargements, a worm gear-wheel secured to said rod and provided with a boss which fits in the other annular enlargement, a worm-gear sup orted adjacent to said worm gear-wheel an meshing therewith, a ratchet-wheel connected with said worm-gear, and devices operated by the cross-head and connecting-rod and operating in connection with said rod for turning said worn1-gear and rotating said piston-rod.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 2d day of January, 1906.
