DERRICK.
SPECIFICATION forming part of Letters Patent No. 268,957, dated December 12,1882.
Application filed October 11, 1882. (No model.)
To all whom it may concern Be it known that we, FEEDRICK O. STARKE and PETER J. CROWLEY, both of Milwaukee,
in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Derricks; and We do hereby declare that the followingis a full, clear, and exact description thereof.
Our invention relates to derricks for unloading coal, ore, 85e., from vessels; and it consists in certain improvements in the same' which look to the economizing of space, as will be described hereinafter.
In the drawings, Figure l is a side view of our invention at work. Fig. 2 isa broken perspective view of the same, and Figs. 3 and 4 are details.
A is a permanent trestle, that may form part of the coal-bin into which the coal from the vessel is to be unloaded. This trestle consists of two horses, each supporting an end of a shaft, a, and this shaft carries a pair of pinions, B B, and on each side of each pinion B we provide a swinging arm, and these arms are arranged in pairs C C C C', their rear ends connected by shaft a, upon which they are adapted to turn loosely, and theirouteror front ends being connected by a shaft, c, and between the arms of each pair we pass a member, D, of our derrick D D.
To the under side of each member D we x 'a ratchet-bar, d, that when the derrick is in place rests upon a pinion, B, and as the pinions turn looselyon the shai'ta they act as rollers, which, while they bear most of the weight of the derrick, yield about their axes and permit the derrick to be slid up easily.
To lock the derrick after it has been adjusted, we provide each member with a plate, E, ,i
having hooked teeth that project 4out to engage with the shaft c between the frontv ends of the arms G GGG', and as the teeth on plates E all slant downward they will ride under the shaft c when the derrick isv being lifted, and
will only engage it from above.
The members D Dare connected by any necessary number of cross-barsf. On their lower ends we provide the members D with plates F, that have straight teeth forengagement with a bar, F', that may be adjusted up or down, so as to rest between any two of the teeth, and form a stop for a car, H', by which the coal or ore bucket H is hoisted.
The lower end of our derrick, `when in position for unloading a boat, is supported by a shaft or bar, G', that passes through suitable eyes on the underside of each member, and this bar passes through rings g on the upper cross-piecesy of two horses, Gr G, which are designed to stand one on each side of the hatch of the vessel to be unloaded, andas the shait orbar G fits loosely in the rings g, the dis-Y tance between the two horses may be adjusted to suit the deck-room.
We usually provide the upper edge of the members D with a rail or tramway to receive the flanged wheels of the carriage H', and we suspend the bucket H from an adjustable hanger, h, by a rope or chain, h', and suitable pulleys that travel up between the members D, and iWe provide ythe bucket with a stop, t', that, when the bucket has been drawn up to the. dumping elevation, strikes a swinging weight, K, and causes the bucket to lose its balance and dump its contents.
The rope or chain It', by which the bucket is elevated, passes over a pulley, I, down under another pulley, I', and thence to any suitable power. After a boat has been4 unloaded by means of a block and tackle, T, in the rigging of the boat, the boat end of the derrick may be lifted, and by a rope, T', hitched to its other or upper end the derrick may be drawn over on top of the bin," to remain there out of the way until it is again needed, and the horses Gr G can be stored in any convenient place, so that my machine, when not in use, may be easily stored in such space as will be available for no other purpose.
In order to get beams of sufficient length and strength for the members D, I make them of three thicknesses or layers of timber, w n w, the outer layers hein g doweled together to form one end of the member, and then mortised out, as at w", to receive the layer c between them, so that each member is composed of layers united by this system of splicing.
It is obvious that we may substitute rollers for the pinions B B and leave off the ratchet plates or bars d without departing from the spirit of our invention, though we much prefer to use pinions and ratchet-bars.
IOO
That we claim as our invention, and desire to secure by Letters Patent, isl 1. Thecolnbination ofashai't carrying rollers or pinions and supported on suitable trestlework with a derriek adapted to slide upon said rollers or pinions, as set. forth.
2. The derriok having toothed plates E, in combination with shaft a, arms C C-C' C, and shaft c, as set forth.
3. The combination of trestle-shaft a, pinions B B, arms C C C C', shaft c, and the toothed plates for engaging with shaft o, as set forth.
4. The permanent trestle and removable or portable horses of the sliding derriok and supporting-shafts, as set forth.
5. The combination, with the derrick, of plates F and stop-bar F', as set forth.
6. The carriage or car having an adjustable depending standard, in combination with the 2c buokethaving a stop orprojectiornt', the tackle for raising the bucket, and a swinging Weight for dumping the bucket, as set forth.
In testimon5r that We claim the foregoing We have hereunto set our hands on this 29th day 25 of September, 18782,in the presence of two Witnesses. e
