On it are two adjustable stops, T1 T2, which S strikes alternately towards the end of a stroke, causing the valve to shift over and expose the other side of the piston to steam pressure.
The two links, LL, are thin springy brass strips slightly curved, and at the rear end pivoted on the binding posts T1 T2. Underneath the other ends solder the heads of a couple of brass nails. The links are held parallel to one another by a wooden yoke, from the centre of which projects a handle.
The current collector, CR, should be well turned up at the end, so as not to catch on the centre rail joints, and not press hard enough on the rail to cause noticeable resistance. The fixed end of CR is connected through T2 with one brush, B, and both wheel bearings with T1. Electrical Fittings. The best source of power to use is dry cells giving 1-1/2 to 2 volts each.
Assemble the rocking lever in its support and the rod forks, and solder on the support. To the back end of R2 solder a steel plate, A, which must be bored for the pin in the valve fork, after the correct position has been ascertained by careful measurement. The stops, T1 T2, are small, adjustable collars, kept tightly in place on R1 by screws. Setting the Striker. Assemble all the parts.
As shown, the switch is in the neutral position and the circuit broken. Multiple Battery Switch. To control the speed of the train and economize current a multiple battery switch is useful. The contacts, C1 to C5, lie in the path of the switch lever, and are connected through binding posts T1 to T6 with one terminal of their respective cells.
Kepler's formula- r1^3 / r2^3 = t1^2 / t2^2 may be written also r1^3 / t1^2 = r2^3 / t2^2 and this again in the generalized form: r3 / t2 = c. Obviously, by each of these steps we diminish the reality-value of the formula. In its original form, we find spatial extension compared with spatial extension, and temporal extension with temporal extension.
The primary PP is wound in two parts, and oppositely, upon a wooden spool W, and the four ends are led out of the oil through hard rubber tubes tt. The ends of the secondary T1 T1 are also led out of the oil through rubber tubes t1 t1 of great thickness.
T3 and T4 are connected with one of the line wires; T1 with the other wire through a battery, B; T3 with the other wire through the buzzer, R. If the stem of K is depressed to make contact with M, the electric circuit of which the battery, B, forms part is completed, and the buzzer at the other end of the lines comes into action.
D, in the apertures, T1, or T2, of the connecting rod. This permits the travel, and consequently the degree of immersion, to be varied. The device requires three wires, two for connecting the lamp with the battery, and one for maneuvering the apparatus through a closing of the contact, B. With Mr.
A piece of wood, 2 inches long, wide enough to fill the space between the rear edge of the clock and the hammer slot, and 1/2 inch thick, has its under side hollowed out to the curvature of the clock barrel. This block serves as a base for two binding posts or terminals, T1 T2. To the back of the other end of the strip solder a piece of 1/20 inch wire, projecting l inch below the strip.
