To all whom it may concern.-

Be it known that I, JOHN W. STOIIJKIRANTZ,

of Buffalo, in the county of Erie and State of New York, have invented a newand useful Improvement in Derricks, of which the following IS a specification.

This invention relates more particularly I to a derrick for transferring rails or freight from cars running on a dock to a boat arranged along the side of the dock, although the same may also be used for other purposes. The object of this invention'is to provide a derrick of this character which permits of "condition for trans ortation. Fig. 7 is a scale,

readily and expeditiously transferring freight. from cars on the dock to aboat, or vice versa,

with a mimmum number of attendants and with the least wear on the working parts of the derrick.

In the accompanying drawings, consisting of five sheets, Figure 1 is a side elevation of my improved derrick. Fig. 2 is a front elevation 'of-one-section thereof. Fig. 3 is a sectional elevation, on an enlarged scale, showing oneof the clamps on amast-care riage. for holding the derrick against horizontal movement when the same is made portable. Fig. 4 is a top plan view of one section of the'derrick. Fig. 5 is a top plan view, on a reduced scale, showing two sections of the derrickarranged for delivering rails or freight from a dock to,a boat alongside of the dock. Fi 6 is a horizontal section taken in line 6 6, ig. 1, but on the same scale as. Fig. 5 and showing the derrick in fragmentary front e evation, on an enlarged showing the means for connecting the carria awfragmentary side elevation of the lower part of the derrick, showing the means for temporarily connecting a mast-supporting es which support the lower ends of the ,two a jacent masts of the derrick. Fig. 8 is tne drawings the derrick is represented in 1ts most complete form in which the same is capable of being transported lengthwisev from one partbf the dock to another to meet different conditions; but, if desired, the samecomprises one or more sections each of which consists, essentially, of a horizontallyrotatin'g mast B, arranged on the dock between the edge thereof and the front side of the trackway or loading-space; a boom (1, pivotally connected at its inner end to the lower part of the mast and capable of being raised and lowered; an upright stage D, arranged on the dock in rear of the trackway or loading-space; a bearing 6, in which the lower end of the mast is journaled;. a bearing 1), in which the upper end of the mast is journaled; a central tie bar or brace E, extending transversely from the top hearing I) to the central upper part of the stage, and two side tie bars or braces E E extending transversely and obliquely from the top bearing 1) to the upper part of the stage on opposite sides of the central tie bar or brace.

The turning of the mast is effected by means of a swinging line or cable F, which passes with its central part around a bull or swinging wheel arranged at the upper end of the mast, while its opposite ends are wound around the swinging drums g g of a hoisting- -machine G, which is mounted on an elevated platform H on the stage. This hoisting-ma-- chine is arranged at one end of the platform adjacent to the rear end of one of the oblique tie-bars, and the two parts of the swinging cable pass obliquely upward from the swinging drums around guide-wheels I I, which are mounted on the stage adjacent to the junction of its top with the rear end of the other oblique tie bar or brace, and then pass along this last-mentioned tie-bar around intermediate guide-wheels i i on the latter to the hull-wheel, as shown in Figs. 1, 2, 4, and 5.

The boom is raised and lowered by means of a boom line or cable J, operatively connected at one end with the outer end of the boom, while its opposite end is wound around the boom-drum j of the hoisting-machine. The intermediate part of the boom-cable passes over a guide-wheel k on the upper caring of the mast, thence obliquely along 55 their booms over ditlerent parts ofthe'boat,

the tie-bar E and around a guide-wheel 7c, arranged at the junction of the tie-bar E and the stage adjacent to the guide-wheels I I, and thence obliquely downward to the boomdrum of the hoisting-machine.

The load to be transferred from the dock or cars to the boat, and vice versa, is raised and lowered by means of a tackle or tackle-hook L, adapted to be connected with the load, and a hoisting-cable or main line Z, operatively connected at one end with the tackle and passing with its opposite end around the oisting or main drum M of the hoisting-machine, while its intermediate part passes around a guidewhcel m at the outer end of the boom, a guide-wheel m at the lower end of the mast, a guide-wheel m on the upper bearing of the mast, and a guide-wheel m on the stage adjacent to the junction between the same and the oblique tie-bar E, that part of the cable Z between the guidewheels m m being arranged obliquely and along the tiebar E? and that part of the same between the guide-wheel m and the main drum M being arranged substantially parallel with the adjacent oblique parts of the boom and mast cables. By thus arranging the guid'e-wheels I 1 k 'm of the several cables at the junction of the stage and the oblique tie-bar E these cables pass in a directline from these guidewheels along the said tie-bar to a point adjacent to the upper end of the mast and also in a direct line to the several drums of the hoisting-machine, thereby reducing the number of guide-wheels for these cables between the mast and the hoisting-machine to a minimum and reducing the wear upon these cables accordingly.

The platform H is preferably higher than the top of the load on the cars, and the hoisting-machine is arranged on one side of the 'mast, which enables the attendant ofthe hoisting-machine to observe the movement otthe load during its entire passage or transfer from the cars to the boat, or vice versa, thus facilitating the operation of loading and unloading and reducin the number of attendants which is usually required for this purpose.

When a derrick of small capacity is required, a single section of my improved der ick, as shown in Fig. 4, will answer the pur pose. For loading boats of considerable length it is preferable to employ two derricks side by side, as shown in Fig. 5, and swing whereby loading and unloading of the same are facilit ated. When these derricksare thus employed, the stages of the same ar connected so as to form practically one structure.

In order to permit of trans orting the derrick from one part oi toe dock'to another for adapting the safne to the position of the hatchways or other conditions, the stages is in use.

ea aces are, provided on their under sides with supporting-wheels 0, which run on longitudinal tracks or rails 0. The lower mast-bearings b are provided with supporting wheels 1), which run on longitudinal tracks or rails p, and the lower bearings b of the two masts are connected by a horizontal beam or bar N, which is provided with the wheels or rollers n, running on the tracks 12. The lower parts of the lower mast-bearings and the stages thus form carriages, which support the mastsand hoistingmachines and the parts connected with the same.

In order to hold the lowermast-bearings and the masts in position relatively to the stages while transporting-the same, movable oblique braces orcoupling-bars Q- are employed, each of which is preferably pivoted at its rear end to the lower part of one of the stages and det achahly connected with one-of the mast-carriages by means of a pin q,passing through corresponding openings in these In Fig. 6 these braces are shown in for coupling the insist-carriages with the stages preparatory to shifting the derrick bodily on the dock. After the derrickhas been thus shifted the coupling-bars are detached at their front ends from the mast-carriagesand folded rearwardly against the stages, as shown by dotted lines-in Fig; 6, in which position these bars are supportedby hooks or brackets r on the stages and leave loaded and unloaded cars into and out of the loading-space between the masts and the stages.

- the main loading-tracks clear for moving the IOQ Any suitable means may be employed for holding the stages and mast-carriages againstmovement on their'tracks when the derrick The preferred means for this purposelshown in Fig. 3) as applied to a mastcarriage consist of clamping-screws S, mounted in brackets s on the mast-carria es apair of inclined claws t,pivoted at thelower end of the clanipin -screw; a link i, embracing these claws an with their hooks underneath opposite sides of the adjacent rail-head, and a clamping-nut it, applied to theupper endof the'clamping screw and bearing against the-upper side of the supporting-bracket sf; For the purpose of freeing this clamping "device from the track and permitting the derrick to be moved horizontally the nut a is first unscrewed and then the link t is moved upoperating to-hold the same Wardly, thereby releasing the claws from the rail and permitting shitting of the derrick along its tracks. r
