Specification of Letters Patent.
Patented Dec. 18, 1906.
Application filed August 18,1906- Serial No 331,173-
To all whom, it may concern:
Be it known that I, GUsrAF ARVID ANDER- SON, a citizen of the United States, residing at IVaynesboro, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Valve- Gear; and I 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.
This invention relates to valve-gear for steam-engines; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure 1 is a plan, view of a double engine provided with valve-gear according to this invention. Fig. 2 is a side view showing the crank-shaft in cross-section. Fig. 3 is a plan view showing the eccentric provided with two straps. Fig. 4 is a side view of the parts shown in Fig. 3.
This invention pertains more particularly to the double engines used for driving large traction-engines. Such engines re uire to be reversed, and on account of the sma 1 space in which it is desirable to have them work the valve-gear is made as simple and with as few separate parts as possible.
A is the engine-bed, provided with crankshaft bearings a. B and C are the two cylinders of the double engine secured to the said bed.
D is the crankshaft provided with cranks B and C. A connecting-rod 11 connects the crank B with the piston-rod of cylinder B, and a connecting-rod c connects the crank O with the piston-rod of cylinder 0. The two cranks are arranged at a right angle to each other.
E is a single eccentric which is operatively connected with the crank-shaft D in any approved manner. This eccentric is reversed by sliding it across the center of the shaft in the usual manner, and for this purpose it is provided with a slot or opening. Any approved construction of reversing-gear may be provided for sliding the eccentric across the shaft.
F is a driving-plate secured to the crankshaft, andf is a bolt or screw for securing the eccentric E to the driving-plate in any desired position or positions. This drivingplate'is illustrated to show a working connection between the eccentric and the crank-shaft which might be used in some cases; but it is preferred to use one of the approved forms of reversing-gear which will permit of the eccentric being slid back and forth quickly, so that the engine may be reversed at any moment and without delay.
G is a single eccentric-strap mounted on the eccentric E. This eccentric-strap is provided with two eccentric-rods H and I. The eccentric-rod H is formed integral with or is rigidly secured to the strap, and the eccentricrod I is connected to the strap by a pin 'i.
- The two eccentric-rods are arranged at a right angle with each other when the center 2 of the eccentric and the other parts are all in the positions shown in Fig. 2.
J is a rocker-arm or bell-crank lever pivoted to the bed by a pin The upper end of this arm or lever is pivoted to the eccentricrod H by a pin 3'. and its lower end is pivotally connected with the valve-stem n of the valve which distributes the steam to the cylinder B.
K is an arm secured upon a rock-shaft 7c, which is journaled in brackets K, secured to the bed. The arm K is pivoted by a pin 7c to the eccentric-rod I. I is also an arm secured to the said rock-shaft at a suitable angle to the arm K, so as to form a kind of bellcrank lever. The arm P is pivotally connected with the valve-stem p, which pertains to the steam-distributing valve of the cylinder 0, by a pin 10.
When the two eccentric-rods are set at an angle of ninety degrees with each other, the same as the two cranks, and when the parts are all arranged as shown in the drawings, it is found that a suitable motion can be obtained for the two steam slide-valves and that both valves can be operated by a single eccentric. A double engine constructed in this manner can be run continuously in one direction or the other and can be reversed as often as required.
If desired, two eccentric-straps G G may be used, as shown in Figs. 3 and 4, instead of a single strap, as shown in Figs. 1 and 2. When two eccentric-straps are used, each eccentric-rod may be formed integral with or rigidly secured to the strap to which it pertains, and it is not necessary for one of the eccentric-rods to be pivoted to its strap.
Whatil claim is- 1. The-combination, with an engine provided with a crank-shaft, two cylinders arranged side by side and operatively connected with the said crank-shaft, and two valve-spindles for the said. cylinders also arranged side by side; of two bell-crank levers fulcrumed on opposite sides of the said valvespindles and having their adjacent ends pivoted to them respestively, and two eccentricroids driven. from the said crank-shaft and pivoted to the outer ends of the two said belLcrank levers respectively.
p 2. "The combination, with an engine provided with a crank-shaft, two cylinders arranged side by side and operatively connected with the said crank-shaft, and two valve-spindles for the said cylinders also arranged side by side; of two bell-crank levers fulcruined on opposite sides of the said valvespindles and having their adjacent ends pivoted to them respectively, a single eccentric driven by the said crank-shaft and provided with an eccentric-strap, an eccentric-rod rigidly connected to the said strap and Ipivoted
