. To all whom/it may concern:

Be it known that 1, STEPHEN I-l. CHASE, a citizen of the United States, residing at San Jose, county of Santa Clara, State of Caliing continuously in one direction and which mechanism is reversible in all its parts by the use of" belts and binder-pulleys with automatically-acting Weights and levers and connections by which either of them may be thrown into or out of action. These objects are attained by mechanism illustrated in the accompanying drawings, in which- Figure 1 is a plan view of my invention. Fig. 2 is an end view of same. Fig. 3 is a front view of same. Fig. 4 is a diagrammatic view of the levers and connecting devices.

It is customary in hauling logs from points where the trees have been out to a mill or to a convenient place for transportation to employ wire cables, which are laid over the most practicable courses from the collecting-station to the point of deposit by means of sheaves, so that the logs may be connected with the cable and hauled over long distances from stationary engines. In like manner finished lumber and other products may be transported outward from the mill, which may be otherwise inaccessibly located, to stations from which the lumber can be transported byordinary conveyances. This invention is designed to provide an apparatus by which the hauling-cable is operated to transport the load, and a return-cable, which is connected with themain hauling-cable, can be actuated to drawthe main cable back to the collecting-pointafter the load has been discharged,

'ning continuously in one direction may be properly reversed.

I have here shown my invention as con nected directly with the saw arbor or mandrel of a sawmill, (shown at A.) Upon this mandrel are fixed two pulleys5 and 6, and upon a counter-shaft B, suitably placed with relation to these pulleys, are corresponding pulleys 9 and 10. Around the pulleys 6 and 10 a belt 3 passes, and around the pulleys 5 and 9 another belt 4 passes. Both these belts are'sufficiently long so that when no pressure is brought upon them they hang slack and power will not be transmitted to either of them from the constantly-running shaft A.

Upon the shaft B, which carries the pulleys 9 and 10, is mounted another pulley 8, and from this pulley a belt 2 passes around a pulley 11, mounted upon a suitably-journaled shaft G. This shaft carries upon it a pinion 12, which may be of cast or other suitable material, and this pinion engages with a gear-wheel 13, carried upon the same shaft with a winding-drum 17. This winding-drum is designed to carry the main hauling-cable 20.

Suitably journaled with relation to the shaft 29 of the drum 17 is another shaft 30, carrying a drum 16, which drum carries the smaller or outhaul cable 22. A pulley 14 is fixed upon the shaft with the drum 17 and a pulley 15 upon the shaft with the drum 16, and the belt 1 extends loosely over these pulleys, so that when tightened power may be transmitted from the pulley 14 to revolve the pulley 15 and drum 16 in unison with the movements of the drum l7 and in such a manner that when one cable is being uucoiled and moving outward the other cable will be correspondingly coiled upon its drum and moved it passes around beneath the pulley 10, thence over the pulley 18 above and to the other side of the pulley 10, thence returning to the pulley 6, said belt 3 adapted to reverse the direction of travel of the shaft B. The pulleys 18 and 19 are so located that the belt will encircle approximately three-fourths of the pulley 10, so as to insure sufficient frictional driving power when the belt is tightened. The pulley 19 is suitably carried at the end of alever 21, fulcrumed, as shown at 21, and upon the outer end of this lever is a weight 34 sufficient to raise the pulley 19 so as to tighten the belt 3, and thus transmit motion from the pulley 6 to the pulley 10. The belt 2, passing from the pulley 8, which is mounted upon the same shaft B with the pulley 10, passes around the pulley 11, mounted upon a shaft O,and when the belt3 is tightened it will be seen from its direction around the pulley l0 and over pulleys 18 and 19 it will revolve this pulley in a reverse direction from the movement of the pulley 6. This motion transmitted through the belt2 toll revolves the pinion 12, and this communicates motion to the gears 13, which drives the windingdrum 17, and thus acts to wind the cable 20 upon the drum 17, and thus haul the distant load toward the drum. When the load has been brought to the desired point of deposit, the lever-arm 21 is lifted about its fulcrumpoint and the pulley 19 is depressed, so that the belt 3 will slip around the driving-pulley 6, and no further motion will be communicated through the pulley 10. This is effected by means of a lever 42, which is located Within reach of the operator. This lever is connected by means of a cord 37 with the lever 21, so that by moving the lever 42 motion is communicated to the lever 21 and the belt 3 is slackened, as previously described. When the cable 20 is to be hauled out again, it it effected by means of a smaller cable 22, which, passing around the drum 16, extends outwardly parallel with the line of travel of the cable 20, and at the outer end this cable passes around a sheave or snatch block, thence returns, so that it may be connected with a hook or other attachment upon the end of the cable 20. It is then desired to transmitmotion in the reverse direction that is, to uncoil the cable 20 and coil up the cable 22. This is effected by means of the belt 4 passing around the pulley 5, thence around the pulley 9 upon the shaft B, so that when this belt is tightened it will transmit motion to the shaft 13 and the pulley 8 in the opposite direction to that transmitted by the belt-3. This belt 4 also normally runs loose and does not transmit motion until tightened. This belt is tightened by means of a binder-pulley 7, mounted upon a fulcrunied lever-arm 7 which carries upon its outer end a weight or weight-carryin g box 35. This lever is released and the weight allowed to act to press the pulley 7 against the belt 4 by means of the hand-lever 41 acting through the connecting-rope 36 upon the lever 7, thus allowing the weight 35 to drop and press the pulley 7 against the belt 4 sufficiently to give the desired frictional contact between this belt and the pulleys 5 and 9.. The belt 2 is kept constantly tight upon its pulleys 8 and 11 by means of the automatically-actuated pulley 33, carried upon the weighted leverarm 33, since it is not necessary to allow this belt to slip. The belt 1, which extends from pulley 14 to pulley 15 of the winding-drum shafts, remains slack while the cable is being wound upon the drum 17, and the drum 16 is revolved and its cable uncoiled by the connection between the cable 22 and the inwardly-moving cable 20. The binder or tightener pulley 25 of belt 1 is carried upon a weighted lever 26, and this pulley is kept away from the belt 1 by means of the connecting-rope 39, extending from the lever to a lever at the operators station. When the cable 20 is to be hauled outward, power to revolve the cable-drum 16 is applied by releasing the lever 40 and allowing the weight on the lever 26 to act and force the binder-pulley 25 against the belt 1, thus transmitting motion from the pulley 14 of the drum 17 to the pul-. ley 15 of the drum 16. The pulleys thus revolve in unison and the pulley 16 hauls in and coils the cable 22, while the cable 20 is correspondingly uncoiled from the drum 17. By this means both movements are effected from the one driving-shaft A without any change in its motion, and when the belts 3 and 4 are both slack no motion is transmitted from this shaft to any part of the apparatus. The tension upon all the belts is such that if any obstruction is met by the incoming load these belts will slip and relieve the strain, so as to prevent the breakage of the hauling-cable or other parts; but the tension is always sufficient to hold the load when no obstructions occur. The tension u pou the belt produced by the binder-pulley 25 while sufficient to communicate motion from pulley 14 to pulley 15 is also such that this belt may slip sufficiently to compensate for the varying sizes of the coils upon the drums 16 and 17. Thus when the cable 20 is being coiled upon the drum 17 it constantly increases the diameter of the coil, while the outgoing of the cable 22, moving in unison therewith, as constantly decreases the sizejof the coil on the drum 16. Therefore in order to cause the cables to move in unison there must be a certain amount of slippage allowed to this belt, which is effected by the means heretofore described. I

The brake block 32, pressing upon the brake-wheel 31 of the drum 16, may be operated by a foot-lever conveniently connected with the operators station, but not here shown. This brake will arrest the motion of the drum 16 when the cable 22 is uncoiled and the drum 17 is brought to a sudden stop.,

IIO

The pulley 28, which is fixed to the shaft B by the side of the pulley 10, serves to receive a band-brake, and this brake stops the movement of all the machinery when running in either direction. It is operated from the necting the cords by which the weighted levers are actuated with the hand-levers at the operators platform, and these hand-levers may be retained in place when the weighted levers have been moved to release the belts by means of rack-bars of any suitable de scription, as illustrated at 50. I

Signals are transmitted to the operator at the platform by means of an electric bell of any suitable description (not here shown) located close to the operator, the wires from the bell and battery extending along the line of the hauling-ropeway to the distant station, so that by completing contact between these wires a signal may be transmitted at any time to the operator to instruct him what should w be done with the apparatus under his control.
