HOISTING=MACHINE.

SPECIFICATION forming part of Letters Patent No. 397,621, dated February 12, 1889.

Application filed May 8, 1888. Serial No. 273,180. (No model.)

To all whom it may concern.-

Be it known that I, Gnonen JAY ANDER- SON, of Test Superior, in the county of Douglas and State of Viscousin, have invented a n ew and Improved Ho isting-Machine, of which the following is a full, clear, and exact description. 7

The object of the invention is to provide a new and improved hoisting-machine, specially adapt-ed for loading and unloading vessels, cars, &c.

The invention consists of certain parts and details and combinations of the same, as will be described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement with parts broken out. Fig. 2 is an end elevation of the same. Fig. 3 is an enlarged end elevation of part of the improvement. Fig. at an enlarged sectional side elevation of the carrier and tripping device; and Fig. 5

is a plan view of the carrier.

The improved hoistin g-maehine is provided with a mast consisting principally of a vertical frame, B, provided on its bottom with a pin, B, mounted to turn in a bearing,

formed on the platform 0. On the upper end 'of the frame B,in its middle, is held a pin, B

mounted to turn in a suitable bearing formed in the ends of the beams D of a suitable frame, D, erected on the platform 0, next to the up right frame B.

From the bottom of the frame B project outward and upward the beams B ,which, in connection with the beams B, secured to the top of the frame B, support the boom E, made of two parallel beams, E and E connectedat the top and bottom by cross-pieces E said beams E and E thereby forming a track on which travels the carrier or carriage F, provided with the usual wheels, F, supporting a frame, F in the middle of which is mounted to rotate a pulley, F over which passes the hoisting-rope G, secured by one end to a trans verse bar, F", held 011 the frame F of the carrier F.

The beams B are united at their outer ends,

which are connected by a link, B with the pin B and from the said ends of the beams B extend the braces B, supporting the lower part of the boom E. From the upper part of the frame B extend the braces B which assist in supporting the upper part of the said boom E, which is thus held on the mast in such a manner that the weight concentrates in the lower part of the frame B, and the latter is thereby easily turned on its pivotsthe pins B and B The hoisting-rope G supports the hoistingbucket H by passing under a pulley, H, mounted to rotate in a frame, H carrying at its lower end a hook, H supporting a bail, H, pi votally connected at its ends to the sides of the bucket H said bucket 11 being limited in its swinging movement by the stops H and H against which said bail H rests alternately, the stops H and H being secured to the outer portions of the sides of the bucket H, as is plainly shown in Figs. 1. and 4;.

On the middle part of the bail H is hinged an inclined rod, H provided on its outer end with a notch, H adapted to engage a projection, H secured on the rear wall of the bucket H Said rod H when engaging said projection H holds the bucket H in a vertical position, so that the bucketsupports the load to be carried. Said rod H is to be disengaged from the projection H byatripping device, 1, consisting principally of a L} shaped lever, l, fulcrumed at I to the outer sides of the beams E and E" of the boom E, as illus' tratedin Figs. 1 and 4. The lover I is provided at each end with an upwardly-extending projection, 1 connected with one end of a spring, I, secured by its other end to the side of the respective beam E or The outer end of the said projection I is also pivotally connected by a link, 1 with a bloek,l, held to slide on top of the respective beams E and E of the boom E, the said blocks 1 being connected with each other by a crosspiece, 1 and the said blocks 'are adapted to be engaged by the wheels F of the carrier F in order to operate the tripping device I. The hoisting-rope G also passes over a pulley, J, mounted to rotate in a block, .1", pivotally c011- nected withthe upper end of the boom E. The rope then passes from this pulley .T to

, pin N and the pulley N a sheave, J supported from a transverse beam, D of the frame D. 'lhehoisting-rope G then extends downward and is connected with a Windlass, K, of any approved construction, and located on the platform ()neend of the block J carrying the pulley J is connected with one end of a rope, L, extending rearward and passing over a sheave, L, supported on a post of the frame I), and the said rope L then extends downward and is secured by its lower end to a cleat, L secured. to the lower end of the said post of the frame 1).

To the front axle of the carrier 1 is connected one end of a .rope, N, extending upward and passing between pins .1 held in the' block J, and then passing on farther upward and over a pulley, if", mounted on a transverse beam, D, of the frame D, and then the said rope extends along the said beam D and passes over a pulley, Y and then under a pulley, l supporting a weight, N, and then the said rope N extends upward and is secured by its end to a cleat or pin, N, secu red on the said beam 1)".

In the frame D is formed a hopper, 0, provided on its lower end with a spout or chute, O, which is adapted to be connected with cars or other receptacles to be loaded. On the front 'end of the hopper O is pivoted a transverse extension-plate, adapted to close the upper front end of the said hopper whenever desired.

7 The operation in as follows: The platform (J usually forms part of a dock, and on the said platform is mounted to swing the mast, so that the lower end of the boom E can be brought over a vessel to be unloaded. The mast, with its boom E, is turned on the pivots B and B by pulling on the rope L or G until the lower end of the boom E is in the desired position, so that the hoisting-bucket H is directly over the hatch of the vessel to be loaded. The rope L is then fastened by its lower end on the cleat L and then the windlass K is operated, so as to unwind the hoisting-rope G, whereby the carrier F by its own weight travels downward on the beam E until the hoisting-lmeket H is directly over the hatch of the vessel. This downward movement of the carriage F causes a downward movement of the rope D, and when the desired position of the said hoisting-bucket over the hatch is reached then the operator fastens the end of the rope X to the pin or cleat in such a manner that the pulley N is in its uppcrn'lost positionthat is, between the The rope N will now prevent a further downward movement of a carrier F at all times, and when the operator now continues to unwindthe rope G from the hoisting apparatus K the said rope G will cause the bucket ll to pass down the hatch into the hold of the vessel. The bucket is then loaded in the usual manner and the rod H holds it in a vertical position by engaging by its notch l-I the projection I1 hen the bucket is filled, the hoisting apparatus K is again set in motion, so as to wind up the rope G, whereljiy the hoisting-bucket H is lifted out of the hold through the hatch until the pulley ll comes in contact with the pulley l of the carrier I A further winding up of the rope (i now causes an upward traveling movement of the carrier F with the hoisting-lnieket H. ()n the upward movement of the carrier h its front wheels, F, come in contact with the blocks l, which are then moved forward and cause an upward swinging movement of the lower part of the lever I by being connected with the latter by the links The middle part of the U-shapcd lever I is thus thrown against the bottom edge I of the rod if, so that the latter is swung upward and out'of contact with the projection H The bucket, on account of being heatier at its front end than at its reaigtilt-s over, turning at the pivot-points the lower end of. the bail ll' As the bucket ll. at this time is directly over the hopper O, the contents of the bucket H are thrown into the said hopper 0, after which the bucket H rights itself and the notch H of the rod H again engages the projection H \Vhen the bucket is loaded, its forward or inclined half is the heavier, and therefore as soon as the latch is released the bucket dumps; but when empty the rear half of the bucket is the heavier, an (1 hence the bucket will right itself, as stated, as soon as dumped. Vhen the carrierF travels upward, as before described, the weight N causes the pulley N to exert a pressure on the rope N, so that all slack of the latter is constantly taken up. Now, the operator again causes the hoisting apparatus K to unwind the h oisting-rope G, an d the carrier F, with the hoisting-bucket H, travels downward until the pulley N carrying I the weight N", is again in its uppermost position, as before described, and the said carrier F is then held in a fixed position directly over the hatch of the vessel to be unloaded. The above-descri bed operation is repeated. "When the carrier F moves downward from its up permost position, the sprin I move the lever I and the blocks 1" back to their former positions, so as to be ready to engage the rod I l again, as before described. I Thus it will be seen that the entire machine is easily operated and the boom on be swung to any desired position and held there, so that the hoistiug-bucket is always over the hatch of the vessel and connects at its upper end with the hopper O, the latter being sufficiently wide to pcrmitthe bucket H to unload when in an angular position, as shown in dotted lines in Fig. 2.

It will further be seen that the entire device is very simple and durable in construction and very effective in operation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the frame D, having a hopper, O, of the vertical mast journaled in said frame in front of the hopper, and havin g an inclined boom, E, extending rearwardly beyond the mast into the frame over the hopper, and a carriage traveling on the boom past the mast, substantially as set forth.

The combination, with the sup1 )ortingframe, and the vertical mast adapted to rotate and having an inclined track-boom extending in. rear of the mast at its upper end, and provided with a trip at said rear end, of a carriage tray'eling on the boom and carrying a dumping-bucket provided with a latch into the path of which said trip projects, substantially as set forth.

3. The combination, with the frame having forwardly-proj ecting top beams, D, and a forwardly-proj ecting base, (7, of the Vertical mast journaled in the said projecting parts of the beams and base, and having an inclined boom proj eeting at its rear or upper end beyond the mast, the carriage traveling 011 the boom, the rope N, passing over pulleys on the frame secured at its ends to the frame and having a weighted pulley, N", suspended from it, the

hoisting-nope G, secured to the carriage and having a traveling pulley, H, under the carriage, passing thence over a pulley onthe carriage to a pulley on the frame, and the rope L, for turning the boom, substantially as set forth.

4:. The combination, with theinclined boom and the carriage travel i n thereon, of the tripping-lever l, pivoted at the upper end of the boom projecting forwardly thereunder, pro vided at its ends with upwardly-extending projections I", springs I", connected to the boom and said 'n'ojeotions, links I, extending rear- \vard'l y from said proj ecti ons, and the blocks 1, sliding on the boom in the path of the carriage and connected to said projection, where by when the carriage forces the blocks rearwardly the lover I will be operated, substantially as set forth.
