HOISTING AND CONVEYING APPARATUS.

Specification of Letters Patent.

Patented March 5, 1907.

Application filed May 12, 1905. Serial No. 260,185.

To all whom it may concern.-

Be it known that we, THOMAS SPENoER MILLER, a citizen of the United States, and a resident of South Orange, in the county of Essex and State of New Jersey, and J OSEPH H. DIoKINsoN, a citizen of the United States,

and a resident of Montclair, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Hoisting and Conveying Apparatus, of which the following is a specification.

Our invention relates to hoisting and conveying'apparatus of the type shown in our Patent No. 814,717, dated March 13, 1906, being in the nature of an improvement thereon.

In the accompanying drawings like characters of reference indicate like parts in all the views.

Figure 1 is a side view of an apparatus containing our invention adapted for logging. Fig. 2 is a detail view of our improved duplex load-carriage and the rope connections therewith. .Fig. 3 is a view in end elevation of that portion of the carriage carrying the ropedrum, and Fig. 4 is a plan view of the same.

Referring now to the accompanying drawings, 1 and 2 are the head and tail supports, respectively, while 3 is the cable or trackway over which travels the duplex load-carriage, (indicated as a whole by O.)

4 is the friction-operated hauling-rope drum of the engine, and 5 is the hauling-rope operated thereby.

The fall-rope of the apparatus is shown at 6 and carries at one end the gripping-tongs 7.

The friction slack-pulling rope drum of the engine is designated by 8, while 9 is the slack-pulling rope operated thereby.

Extending to the tail-support and back again and having its tail made fast to the carriage O is the outhaul-rope 10.

In our patent above referred to the carriage is so constructed that a large amount of play and flexibility in all lateral directions is permitted between the two members of the carriage; but in the present case we have shown such carriage members joined by a connecting-frame which embraces a construction found to be preferable in some particular instances. The present duplex carriage comprises the parts M and M, connected by the rigid frame E, which frame may be of any suitable material, such as metal or wood, and is preferably rectangular in conformati on, although, of course, itwill be understood that it may be of any desired shape. The frame we have shown comprises the longitu dinal top and bottom side bars 11 and 12, connecting the carriage members, while 13 and 14 are straps or plates having their ends bent downward and outward relative to the main portion of the straps, the latter being arranged vertically relative to the carriage sides, with the ends extending beneath the longitudinal connecting bars. At 15 are shown bolts or other fastening means passing through and connecting the side bars and the straps with the carriage sides, while 16 are diagonal struts or braces adapted to give additional strength and stability to the frame.

Guide- sheaves 17, 18, and 19 are secured to the head-support, while 20 is the guidesheave at the tail-suppoit. 21 and 22 are the traction-wheels of the duplex load-carriage running on the cable or trackway, one wheel being carried by each member of the frame, while 22 is a small supporting-wheel journaled in the frame portion M of the carriage and adapted to form a guide andsupport for the main cable.

D is the load-carriage drum, composed of a plurality of parts d, (Z and (i the part d being preferably of less diameter than the parts d and (Z A fall-r0pe pilot-sheave 23 is linked by the clevis 24 with the carriage member M, so as to have freedom of movement in all directions.

25, 26, 27, and 28 are guide-sheaves journaled on the carriage between the strips 13 and 14 and the sides of the carriage members, such sheaves being adapted to steady the opposing run of the outhaul-rope, while 29 and 30 indicate idler-pulleys on the part M for the ropes passing around the load-carriage drum.

From the above description the construction of the apparatus will be readily ap arent, and the operation is substantially as follows:

. When a log is being hauled or lifted by the fall-rope 6, the hauling-rope 5 will be hauled in, and the slack-pullingrope will be paid out under tension by the drums of the engine.

WVhen the fall-rope 6 is being carried out to take a new log, the engine is so operated that the rope 5 is outhauled by the inhaul of the rope 10. When the duplex carriage is propelled toward the head-support, the ropes 5 and 9 are both inhauled but the speed of the drum 8 is sufficiently in excess of the speed of the drum 4 to cause more or less slip between the friction-surfaces of the frame. The distance of the pilot-rope sheave from the rope-drum D is such as to give a sufliciently fair lead to the drum part D, upon which said rope is coiled, and the pilot-rope sheave relieves the drum D from the lateral movements and strains that are encountered in hauling logs from various directions.

The construction of the engine and the operation of the same is substantially like that described in my copending application above referred to, and as this is a well-known form of engine it is unnecessary to here enter into a detailed description of the same. It will be noticed that the duplex carriage, such as herein shown and described, embodies the essential and desired features of simplicity, durability, and strength and is of especial advantage in hauling very heavy loads, such as logs or the like.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is-

1. In a hauling apparatus in combination two stationary drums, a cable or trackway, a duplex carriage thereon, a rigid frame connecting the parts of the carriage, a rope-drum mounted on one part of the carriage and driven from the stationary drums, and a pilot-sheave mounted on the other part of the carriage.

2. In a hauling apparatus, in combination a cable or trackway, a duplex carriage consisting of separate members, with a rigid frame connection between the same, a stationary drum mounted outside the carriage, a rope-drum mounted on one of said members and driven from the stationary drum and a pilot-sheave on the other of said members.

3. In a hauling apparatus in combination a cable or trackway, a duplex carriage comprising separate members, a frame rigidly connecting the two parts of the carriage, a rope-drum mounted on one of said carriage members, a pilot-sheave carried by the other of said members and means outside the carriage for driving said rope-drum in opposite directions.

4. In a hauling apparatus a duplex carriage comprising separate members, one of said members having a rope-drum provided with a plurality of drum-barrels of different diameters, the second member-being spaced apart from the drum-carrying member, a swiveled pilot-sheave carried by the second member, and a rigid connection between said members.

5. In a hauling apparatus a duplex carriage comprising a member having a plurality of drum-barrels of different sizes, a second member separated from the first-mentioned member, a rigid connection between said members comprising a frame formed of a plurality of longitudinal bars, secured to the sides of the carriage members and strength ening-braces connecting said longitudinal bars, and a rope-support carried by the carriage.
