Application filed October 8, 1913.

Specification of Letters Patent.

Patented Apr. 28, 1914.

Serial No. 794,082.

To a]? 'LlllO/Ib it may concern Be it known that I. Join" T. Banner, a citizen of the United States, residing at Fort Kent, in the county of Aroostook and State of Maine, have invented new and useful Improvements in Portable Devices for Handling Long, Heavy Articles, of which the following is a specification.

This invention relates to improvements in devices for handling logs or other long heavy articles, and especially articles of uneven length, and it is particularly designed to enable the operator to place the articles with the ends at one end of the load in the same vertical plane. It is designed for handling logs in the woods but may be used in handling other articles such as structural iron.

In the drawing herewith accompanying and making a part of this application, the figure is a perspective view of the device, some parts being broken away to show parts otherwise concealed.

In said drawing, the operating device is shown mounted upon a sled consisting of two runners A and B securely bolted together by cross bars C, D, and E. In one of the runners, near its end, are pivotally mounted two uprights F, each preferably composed of two bars separated at the foot and tapering toward the top. These uprights. which may be called the derrick frames. are pivotally attached to the runner, preferably by having their lower extremities stepped in sockets G made in the runner, the sockets being larger than the feet of the frames. whereby said frames may be tipped sidewise relative to the sled. The frames are maintained in any given position by means of braces H pivotally attached to the opposite runner. as seen at I, and provided with means for adjustably attaching the free ends to the derrick frames, preferably to cross bars J, the braces being provided with a series of holes K and with screws or other fastening devices L adapted to take into receiving holes M in the cross bars.

In devices of this kind heretofore made, only a single derrick frame is employed. This is objectionable because in this case the hoisting tackle must be attached to the article in such a way that it will nearly balance, and when thus attached and brought into position in the load, it will be very difficult to place the various articles, when of uneven length, so that the ends will be in substantially the same vertical plane which is necessary especially when loading logs upon sleds or cars. T o obviate this objection, I provide two derrick frames, one near each end of the sled, and provide two sets of hoisting tackl operating from a common draw rope. The operator can then place the lifting tackle always at the same distance from one end of the article, so that when it is hoisted to position the ends will come in proper place. The hoisting tackle on each frame is similar and consists of a block N secured near the top of the derrick frame, and another 0, to the sled frame. The hoisting cable P has one end with plenty of slack attached to the sled frame, preferably to a cleat Q on the middle cross bar. Thence it passes under one of the end cross bars, thence freely through a loop S at the top of the frame, thence through a hoisting block T, thence through the pulley N at the top and thence around the pulley 0 attached to the sled frame. The free ends of each hoisting cable are then secured to a common coupling R, to which the motive power is attached.

The derrick is prevented from tipping sidewise by means of guy ropes U, one end attached to a suit-able post V, whence it passes over pulleys attached to the top of the derrick frame and thence under one of the end cross bars and around the middle cross bar to which it is fastened in any convenient manner as by means of a cleat- X.

The operation of my improved device is as follows: The derrick may be moved on the sled frame to a position at one side of the vehicle upon which the articles are to be loaded. By reason of the pivotal connection of the derrick frames with the sled frame, they may be made to tip at any desired angle to the vehicle, and when properly positioned, they are secured in place by means of the guy cables, as before described. The two hoisting blocks are then carried to the place where the articles to be loaded are located and attached to the article by means of any suitable attaching device, chain or rope Y, for example, one being placed at a Suitable distance from one end of the article, so that, when the article is raised, it will, whatever its length, have its front end properly positioned relative to the end of the vehicle. The power is then applied and the article is dragged or lifted into position, the two hoisting blocks being spaced beyond far enough to balance the article, whereby,

when lifted upon the derrick frames, the

for attaching the tackle to the logs at two points spaced apart from each other, one being adapted to be attached to the article at a predetermined distance from the end, whereby one end of the article will auto matically assume a predeterminial position in the load.

in a deYice of the character described, a sled, two derrick frames pivotally mounted thereon. one at each end of the sled runner, means for providing YQl'tHttl adjustment to said frames, hoisting tackle mounted on each frame, each con'lprising a fixed block attached to the top of the frame, a fixed block attached to the sled frame, a, movable lifting block and a fixed ring secured to the top of the frame, a cable secured to the J sled frame, thence passlng through said ring, 5

thence tl'n'ough the lifting block, thence through the block at the top of the derrick frame and thence through the block at the sled frame, means for attaching the httmg from each other, one being at a predetermined distance from the end thereof, and means for coupling the draw ends of the cable together, whereby both lifting blocks rise or fall simultaneously.

3. In a device of the character described, a sled, two derrick frames pivotally mounted in one of the sled runners, one near each end. braces for providing Yertical adjustment for said frames, each frame being provided with a hoisting tackle, each comprising a fixed block attached to the top of the frame, a fixed block attached to the sled frame, a fixed ring secured to the top of the frame, a movable lifting block, a cable remm'ably secured to the sled frame, thence passing through sa d ring, thence through the lifting block, thence through the block at the top of the derrick frame, and thence through the block atthe sled frame, the cables in front of the ring being of sufficientlength topermit the lifting blocks to have a large range, means for attaching the lifting blocks to the article at points spaced apart from each other, and means for coupling the draw ends of the cables together, 1 whereby both lifting blocks move simul: taneously.
