IMPROVEMENT IN HAU'LING- UP LOGS.

The Schedule referred to in these Letters Patent and. making part of the same.

To all whom it may concern:

Be it known that I, SIMON H. RICHARDSON, of

Bangor, in thecounty of Penobscot and State of Maine, have invented certain new and useful Improvements in Hauling up Logs into Saw-Mills; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

'lhnature of my invention consists in so arranging the machineryby which the power is multiplied power supplied tothe haul-up-wheel, sometimes called the nigger-wheel, as to allow a more simple arrangeinent of gear or friction-wheels, and to omit, entirely, the use of a belt, and, at the same time, to allow the haul-up-wheel to be reversed, so that thechain can be carried back directlyfrom the wheel to the logs, thereby preventing the necessity of running the chain entirely -01f of the wheel before it can be carried back.

In theaccompanying drawings- AA A A is the frame which holds the machinery, so that the different parts occupy the same position and transmitted from the water-wheel, or from the .relative to eachother that those parts would occupy when running in a mill'.. I

B represents the part to which power is applied, and which, ordinarily, would be'a horizontal waterwheel or motive power.

O is a shaft, connecting B with a pulley or wheel, D. E is a frictionpulley or wheel, which is connected lay the shaft F with the beveled gear'or friction-wheel H is a gear or f'rict-ion-wheel, which runs in connection with G, and carries the shaft I, and is generally called a nigger-wheel.

J is a friction-wheel, which is arranged on a movable shaft, K, in such a manner that it may be thrown into contact with the wheels D and E simultaneously while those wheels are separated from each other, and

- thereby transmit a motion tothe wheel E which shall be the reverse of the motion transmitted to E when in direct contact with D.

M is alever, by which the wheel D is thrown into contact with E, or removed from such contact.

If is a lever which acts on the movable box L, and carries the wheel J into contact with the wheels D and .E. For convenience, the lever N may be fastened to the lever M, and whenever the lever M is moved forward from left to right, the wheel D is thrown out of contact with E, andthe wheel J is thrown into contact with D and E by the same motion.

To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

I provide a water-wheel, B,.which is usually located so'as to draw water from the fiume independently of the other machinery, or the power may be supplied by steam with about the same arrangement The waterqvheel located at B, but not necessary to be fully shown, is connected by the shaft 0 with the friction-wheel D. I provide the friction-wheel E, and connect it by the shaft 1 with the beveled friction or gear-wheel G. I provide the beveled friction or gearwheel H, and attach the shaft I. I provide the friction-wheel J, and attach itto a movable shaft, K. I provide the levers M and N. I men place the abovenamed parts in the same relative positions as shown in the drawings. I

In operation, the power is applied'hy'a water-wheel, or any other power, at B. ..'1he wheel-B revolves,

carrying with it the shaft 0 and wheel D. Tllc'lever, M is thrown to the left, carrying the wheel D to the right, and into contact with the wheel E. The wheel E revolves, carrying the shaft F and beveled wheel G.- The wheel G is intended to be kept always in contact with the wheel H, and, consequently, when E revolves H must revolve, and impart motion to the shaft I, upon which a chain is wound when in use.

This chain is heavy and long, and being free at each end, one end is thrown over the shaft and passed around it until coils enough are formed around the shaft to keep the chain from slipping with the load. The forward end is allowed to fall-under the shaft as it gains forward. When the logs are hauled up as faras desirable, the chain will not be wound wholly up, and there may be one-half or one-third of 'the chain still between the logs and the shaft.

Now, by the usual process, the shaft cannot be reversed in its revolutions, but the chain must be run forwardwholly off the shaft before it can be carried back, or else the revolution of the shaft must be reversed by hand-power, and just here we find an im portantimprovement in the arrangement of the wheel J interposed between the wheels D and E, in such a manner as to reverse the revolution of the wheel H and shaft I at pleasure, and thus to facilitate the use of the chain at any required length.

A second advantage gained by this arrangement is found in dispensing with the use of a belt. The only other arrangement deserving of comparison with this, is one now in g'eneralnse, and'which necessitates the use of a belt. Bolts are always expensive and always needing-repairs, and in such he. vy work as is required for hauling up logs, heavy and expensive belts must, of necessity, be used.

A third advantage results from dispensing with so much of the usual amount of machinery that a more simple and compact arrangement of the parts is practicable, and considerable .of the space usually occupied is saved. This is an important consideration, as

will readily be understood, even by those least familiar with saw-mills, for allthe room occupied bythe haul-up, and its necessary machinery, must be taken out of the most central and most valuable roomlin a mill, and all the space which'ean be saved here is an advantage of no light importance.

A fourth advantage arises from the facility with which the machinery can be arranged for convenience in handling, for the wheels D, E, and J may all be placed under the floor of the mill, and there need be nothing seen above the floor but thehandles of the levers, by which they are controlled.

A fifth advantage arises from' the entire noiselessness with which this machinery can be run, and the absence of any jar to the difi'erent parts, the wheels H and G, whether geared or friction, are always in proper codneotion, and the power is transmitted through the friction-wheels D E, preventing any sudden jars or strain, such as would result from the contact of geared wheels; and, finally, this arrangementis'so simple that it seldom needs repairs, and when it does need them, they are easily and cheaply made.

Whatl claim as my invention, and wish to secure by Letters Patent,is-

1. The arrangementof the shaft and wheel 0D, with the wheel, shaft, and wheel E F G, in combination with the wheel and shaft H I, all as shown and described, for the pnrpose'of hauling np logs.

2. The combination of the shaft and wheel G D, with the wheel, shaft, and wheel, E F G, the wheel and shaft. H I, and the wheel -J, with the levers M and N, in the manner and for the purposes'shown and described.
