WATER-WHEEL GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 434,381, dated August 12, 1890.

Application filed December it, 1889. Serial No.832,557. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS H. COULTER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in WVater-lVheel Governors; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

I My inventionrelates to improvements in water-wheel governors, which will be fully hereinafter described and claimed.

The object of my invention is. to regulate the flow of water to a turbine or other form of Water-wheel by a compact in echanism which will be sensitive, yet sufliciently powerfulto operate any gate.

The mechanism is illustrated in the accompanying drawings, in WlllCh Figure 1 is a top view of the governor with portions omitted. Fig. 2 is aview of the left side of the same with parts to the rear omitted. Fig. 3 is a transverse section on line Fig. 1. Fig. at is a transverse section on line 1 Fig. 1. Fig. 5 is an enlarged end View of the driving-arm. Fig. 6 is a front view of the shifting device.

Like letters and numerals designate like parts throughout the several views.

Ais the base, which, with the several standards supporting the shafts, forms the frame of the machine. To the shaft I at the right end is attached the driving-pulley H, in the center the driving-arm 1, and on the left end the pulley K. External to the drivingarm are the miter-wheels B and G, and to the sides of which are attached the ratchet-wheels B O. The miter-wheels are loose on the shaft, and the other parts are rigidly attached.

of dogs and pawls. The several parts of the I two ends are identical, and one set would suffice; but the two parts combined give amore immediate motion to the gate-rod. The relation of the several parts could no be clearly shown in Fig. 1, and are therefore more fully illustrated in Figs. 3, 4:, and 5.

At Fig. 3 is shown the left ratchet-wheel B, and the miter-wheel to which it is attached is only shown in outline by the external cir cular dotted line. The inner line shows the circuit of the end of the dogs, and the arrow in this line indicates the direction of the motion. The two pivots 8 and 9 support the dogs and pawls in the ends ofthe arm. The pawls 2 on the outside of the arm are rigidly attached to the pivots. Over each of these are flat springs 3, which bear on pins in the sides of the pawls. These serve to hold the pawls in position when either in or out of the ratchetwheels, and notches may be used in the springs to more effectually hold the pawls in proper position. A compound dog comprises part 7, rigidly attached to pinion 8 and having segmental cogs on its under surface that engage a like series of cogs on the part 6, which has a projection to engage the throwing-arm 18. The under part is held on a pin in the extension 5 ofthe driving-arm. WVhen the under part of this compound dog strikes the throwing or shifting arm 18, the pawl 2 is made to engage the ratchet-wheel B and the miter-wheel B is made to rotate. The shifting-arm is held on the square bar 16, which is held in a frame 17, attached to the base, and within the slots of which the same freely moves laterally. Vhen the shiftingarm 18 so moves as to engage the dog'19, the pawl is thrown out of the ratchet-wheel and the miter-wheel ceases to rotate, and when the dog is struck the same effect results. The rod 10 connects the two opposite disengaging-dogs, and they therefore move simultaneously as one or the other is struck. The relation of these parts is shown at Fig. 4, and the relation of the compound engaging-dogs and pawls to the driving-arm, ratchet-wheel, and miter-wheels is shown at Fig. 3. The pulley K is connected by the belt L with the pulley J, which has four pins 8 near its periphery and equidistant apart. This pulley is supported on a spindle held in an arm of the frame. To the standard N is pivoted the arm or lever M. At the end, to engage the pins, is fastened the metallic plate t, which as it springs relieves the jar consequent upon the pins striking the same as the pulley J revolves.

O is a weight used to keep the outer end of the lever down against the pins and overcome the weight and friction of the connecting parts. The arm 26 is attached at its inner end to the standard, and to its outer end is pivoted by bolt 21the rod 14, which at its lower end is connected to the bar 15, which is jointed to the shifting-arm 18. The arms 12 and 13 are connected to the rod 14 near the top and about equidistant from its pivot. The pulley J and the weight 0 cause the le ver M to oscillate, engaging usually alternately said arms 12 and 13. This produces a reciprocating movement of the shiftingarm 18.

The operation is thus: The shaft E is connected by miter-gear or otherwise to the gaterod of a water-wheel. Motion is given by a belt from the main shaft over the pulley H. The driving-arm 1 is made to rotate, and when moving slowly the shifting-arm 18 would be brought to engage the compound dog 6 and 7. This would throw in the pawl 2 and cause the miter-whee1 B to rotate, and this, by means of the worm-gear, would rotate the shaft Eto open the water-wheel gate. W'hen'the speed increased suificiently, the shifting-arm 18 would be struck by the disengaging-dog 19, and the movement in opening the gate would be discontinued, and if the speed became too great the shifting-arm would be thrown so as to engage the compound dog to the right. This would give motion to the miter-wheel G, and as a consequence the action of the gate would be reversed. The effect of the pulley J with its pins on the weighted lever M is to keep the shifting-arm in rapid vibration, and as this reverses the motion, depending on the speed of the main shaft, the motion is thereby regulated. The two disengaging-dogs are intermediate to the engaging-dogs, and consequentlyone pawl is disengaged before the other is engaged.

The same device may be used in regulating the motion of a steam-engine.

Having f ullydescribed myinvention,what I claim, and desire to secure by Letters Patent,

1. In a speed-regulator, the combination of the pulley H, driving-arm 1, provided with the compound dogs of parts 6 and 7 and pawls 2 2, held on separate pivots, the disen gaging- dogs 19 and 20, loose miter-wheels B and C, ratchet-Wheels B 0', attached thereto, miter-wheel D, worm-gear of parts G and F, the latter on shaft E, pulleys K J, the latter having engaging-pins S and the two pulleys being connected by the belt L, weighted 1cver M to engage said pins, rod 14, with engaging- arms 12 and 13, connective bar 15, and the reciprocating shifting-arm 18 to throw said pawls out and into the ratchet-wheels as the speed varies the motion of the said weighted lever, substantially as shown and described.

2. The mechanism for reversing motion, the pulley H, driving-arm 1, provided with the compound dogs of parts 6 and 7 and pawls 2 2, held on separate pivots, the disengagingdogs 19 and 20, loose miter-wheels B C,ratcl1etwheels attached thereto, and miter-wheel D, held continuously in gear with the former miter-wheels, these several parts being in combination, substantially as set forth.

In testimony that I claim the foregoing as my own I afiix my signature in prcscnce of two witnesses.

THOMAS H. COULTER.
