REVERSING-LEVER FOR STEAM-ENGINES.
SPECIFICATION forming partlof Letters Patent No. 418,760, dated January 7, 1890.
Application filed May 17, 1889. Serial No. 311,148. (No model.)
To au whom it may concern.'
Be it known that we, THEoDoRE MICHAEL SHEARER and J AMEs WILLERED MCKEE, citi zens of the UnitedA States, residing at Butler,
5 in the county of Butler and State of Pennsylvania, have invented new and useful Reversing-Levers for' Steam-Engines, of which the following isa specification.
This invention has relation to reversing- Io levers for steam-engines, and the objects in view are to Jform a direct connection between the link and the reversing-lever, said con- .nection being of such a construction as to permit the vibrations of the bar and yet be under perfect control of the lever. Other object-sand advantages of the invention will hereinafter appear, and the novel features will be particularly pointed out in the claims.
Referring to the drawings, Figure lis a side elevation of a link, its connection, and reversing-lever, constructed in accordance with-our invention. Fig.2 is a perspective of the connecting device employed between the link-bar and the reversing-lever. Fig. 3 is a longitudinal vertical section of said connecting device.
Like numerals of reference indicate like parts in all the figures.
1 represents the engine block or base, upon and the steam-cylinder 3. At the opposite end of the bed-plate is mounted "a cam-shaft 4, upon which move the cams 5, and from which project toward the cylinder the cam- 3 5 rods 6. At the opposite end of the cam-rods 6 are connected the usual link 7, which is of` which is mounted the usual bed-plate 2 nally-opposite corners of the connection areA mounted for movement within the passage, 5o and to the extreme forward end of which is connected the link 7 by a pivot-pin 19.
20 represents the reversing hand-levelgthe lower end of which is inserted in the vertical passage of the connection. 5 5
Upon the rear face of the rear plate 12 there projects a hollow boss or collar 21, which takes over the laterally-projecting stud 9 and oscillates thereupon. A lug 22 projects from the outer Wall of the boss and into a curved 6o slot 23, formed in a plate 24, secured to the bed-plate, the end walls of the slot serving to limit the oscillations of the lever, the connection l0, and consequently the bar 18 and link 7. By this construction it will be apparent that a positive connection between the link and lever is provided, by which the link is under complete control of the engineer, and yet the construction of the connection is such as to permit of the vibration of the link.
Having described our invention, what we claim is- 1. The combination, with a link, of a linkbar, a lever arranged at an angle to the bar, and an intermediate connection for the reception of the latter and bar, and constructed to permit of the reciprocations of the latter, substantially as specified. .l
2. The combination, with a link, of a linkbar pivoted thereto, a hand-lever arranged at 8o an angle to the bar, and a connection arranged intermediate with the bar and the lever and provided with angularly-disposedA slots or passages, one for the reception of the leverv and one for the bar, substantially as specified. A.
3. The combination, with .a link, of a linkbar pivoted thereto, a reversing hand-lever arranged at au angle to the bar, and an intermediate connection for the bar and lever and 9o provided with anti-friction rollers arranged at both sides of the bar, substantially as specified.
4. The combination,with alink, of a pivoted connecting-bar connected therewith, a hand reversinglever arranged at an angle to the bar, and a connecting device provided with passages for the bar and lever and pivoted to the bed-plate, and a stop arranged to limit the movement of the connection, substantially as specified.
5. The coxnbination,\vith a link, of a pivoted connecting-bar, a lever for operating the bar, an intermediate connecting device for the reception of the bar and lever provided With a bearing-boss mounted upon a stud affixed to the bed-plate, and with a laterally-proj ecting pin or shoulder adapted for movement in a curved slot formed in a plate mounted on said bed-plate, substantially as specified.
6. The link 7, mounted in the Ways 8 and connected, as at i), with the bar 18, in combination with the connection 10, consisting of l[he opposite plates 11 and 12, spaced to form passages for the bar and lever 20 and provided with the friction-rollers 17 and the rearwardly-projecting hollow boss 21, having the shoulder 22, said boss being mounted upon the stud il, projecting,` from the bed-plate,
and the plate 24, mounted on the bed-plate and formed with a curved slot 23 for the reception of the lug 22 and adapted to limit the movement of the connection, substantially as specified.
7. The curved link 7, the ways 8, in which the link Works, the shaft 4, the rods G, connecting,r the link with the shaft, the linkbar 18, connected to the link, the hand-lever 20, and an intermediate connection for the reception of the link-bar and lever and constructed to permit the reciprocations of the link-bar, as set forth.
In testimony that We claim the foregoing as our own, we have hereto affixed our signatures in presence of two Witnesses.
