SPECIFICATION forming part of Letters Patent No. 430,241, dated June 1'7, 1890.

Application filed September 25, 1889. Serial No. 325,021. (No model.)

To all whom it may concern:

Be itknown that I, GEORGE HENRY WAR- REN, of \VestSuperior,in the county of Douglas and State of NVisconsin, have invented a new and usefullmprovement in Hoisting Apparatus, of which the followingis afull, clear, and exact description.

My invention relates to an improved hoisting apparatus especially adapted for use in being in section.

removing merchandise and other articles from the hold of a vessel and delivering the same upon the dock or into a vehicle upon the shore.

The invention has for its object to provide a device of simple and durable construction capable of being expeditiously dropped from the shore or dockover a 'vessels hatchway, and one which will not be affected by the rise and fall of the tide.

A further object of the invention is to provide a device which when not in use may be elevated conveniently out of the way. i

The invention consists in the novel constru ction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

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

Figure 1 is a plan view of the boom, the derrick being in horizontal section, taken on line at of Fig. 2. Fig. 2 is a side elevation of the boom in position over the hatohway of a vessel. Fig. 0' is a detail sectional view, illustrating the manner in which the derrickchute and the boom are attached to the derrick. Fig. 4 is a vertical section through the elevating-bucket of the derrick, illustrating the door open and in position to deliver its load to the upper delivery-chute of the apparatus. Fig. 5 is a longitudinal vertical section through the car and a portion of the track upon which the car travels, illustrating the car as locked in position to elevate a load from the hatchway. Fig. 6 is a view similar to Fig. 5, the car beingillustrated in position to carry the load to the derrick. Fig. 7 is a rear elevation of the derrick, the guide-arms Fig. 8 is a transverse section through the derrick and boom, illustrating the upper supports thereof in side elevation; and Fig. 9 is a similar section taken near the lower end of the boom, illustrating the end supports in elevation.

I will first describe the construction of the derrick and then the construction of the boom.

The derrick consists of a horizontal platform 10. having attached thereto wheels 11, adapted to travel upon a track or tracks 12, as illustrated in Figs. 1 and 2, and two perpendicular spaced standards 13, projected upward from the base or platform 10, the said standards being united at the top bya crossheadle. Upon opposite sides of each of the standards 13 a metal plate 145 is secured, as best illustrated in Fig. 1, which plates extend beyond the inner faces of the standards. Upon the forward set of plates let a frame A is held to slide, consisting of an upper bar 15 and a lower bar 16, with side pieces 17 con-' necting the said bars, as shown in Figs. 3 and 7. To the upper portion of the frameA one end of a rope or chain 18 is secured, which rope or chain passes upward over two pulleys 19 and 20, pivoted in horizontal alignment with the crossbar located at the top of the derrick. The-pulley 20 is pii oted beyond the side face of the derrick, and the pu ley 19 is provided with a ratchet capable of being engaged by a pawl 21, as shown in Fig. 7. The end of the rope which is passed over the pulleys has attached thereto a weight 22, adapted to take up the slack of the rope 18 when the frame A is elevated. This frame A, as aforesaid, is free to slide up and down upon the guide-plates 14 of the derrick.

Upon the platform 10, at one side of derrick, two longitudinal standards 23 the are

secured, in which standards, at or near the center, a spindle 2a is journaled, carrying a friction-wheel 25, and at each side of the said spindle drums 26 and 27 are respectively journaled, provided with friction-wheels adapted to contact with thefriction-wheel 25'of the spindle. The spindle 2a is connected with any suitable form of engine 28 by a pitman 29. The drums are not journaled directly in the standards, but in an eccentric 30, which eccentrics are held to turn in the standards, and each eccentric has attached centrally thereto a crank-arm 31, located outside of the forward standard, as illustrated in Figs. 1 and '7. By. pushing the extremity of the crank-arm 31'of the drum 26 downward the friction-wheel of the said drum is made to contact with the friction-wheel of the spindle, and when the crank-arm 31 of the other drum 27 is elevated the friction-wheel of this latter drum is made to contact with the spindle-wheel. The crank-arm of the drum 27 is connected by a rod 32 with the outer end of a lever 33, which lever is fulcrumed at or near its center to one of the standards 13 of the derrick near its top, as best shown in Fig. 2. A second lever 34 is pivoted above the lever 33, being provided at its rear end with a counterpoise-weight 35. This upper lever 34 at its forward end is connected by a rod 36 with the crank-arm 31 of the drum 26.

To the drum 27 one end of a rope or chain 37 is secured, which rope or chain is carried upward over two grooved pulleys 38, journaled in the cross-head 14 of the derrick, and from thence downward between the standards at the rear of the derrick to a connection with the bucket 39. This bucket 39 is illustrated in detail in Fig. 4, and has attached to its forward face clamps 40, adapted to engage with and travel upon the rear guideplates 14 of the standards, as shown in Figs. 1 and 2. The bucketis provided with a door 41 in its outer or rear side, which door is hinged at the top, as illustrated in Fig. 4, and is normally held closed by a spring 42, secured to the bottom of the bucket, which bottom is preferably inclined down ward, the said spring being made to extend beyond the door when the latter is closed. This bucket 39 is elevated when desired by pressing down the lever 33, which throws the drum 27 in contact with the revolving spindle 24, whereby a rotary movement is imparted to the drum and the rope 37 wound thereon. From each standard 13 horizontal arms 43 are rearwardly projected below the lever 33 and supported from the top of the standard by a suitable brace-bar 44. The two arms 43 are connected by two spaced transverse beams 45, purposed to travel at each side of a coping 46 upon a dock or trestle-work 47, located at quite. an: elevation above the dock or trestle-work upon which the base of the standard travels. These transverse beams 45 are adapted to guide and steady the derrick as it is rolled upon the lower dock to carry the boom (hereinafter described) over the several hatchways of the vessel, and in order to prevent, friction rollers 47 are preferably journaled between the guide-bars 45 to contact with the top of the coping, and another set of friction-rollers 48 is journaled upon the under edges of the guide-bars to contact with the front and rear sides of the coping.

Between the brace-bars 44 of the arms 43 a downwardly-extending chute 50 is attached, so located that any material emptied therein will pass out therefrom into the car 51, as shown, or other vehicle placed to receive it.

The door of the bucket 39 is opened when said bucket is elevated by the outer end of the retainingspring 42 contacting with the forward end of the chute 50, as shown in Fig. 4. 7

Upon the upper bar 15 of the sliding frame A the rear end of the boom B is pivoted, and upon the lower bar 16 of said frame the rear end of a chute 52 is made to rest, which chute is held in a downwardly-inclined position by a chain 53 attached to its forward end, which chain is also secured to the upper bar 15 of the sliding frame or to the rear end of the boom B, as shown in Figs. 2 and 3. This chute is so located that when the bucket 39 is at its lowest point any material emptied into the chute will pass from thence into the bucket.

The boom B consists of two parallel spaced side bars 54, united at their upper and lower ends, and having attached upon the upper edge a track 55. The boom is supported in a downwardly-inclined position by attaching thereto between the center and the rear end a yoke 56, to which yoke a cross-bar 57 is secured, and to the ends of said cross-bar legs 58 are hinged, as illustrated in Fig. 8, and to the under edge, at thelower end of the boom, a cross-bar 59 is rigidly attached, having pivoted to each end legs 60, as illustrated in Fig. 9, the legs 60 being much shorter than the legs 58. These legs areadapted to contact with the deck of the vessel, one set at each side of the hatchway, as illustrated in Fig. 2.

Upon each side bar 54 of the boom, between the center and the end, a buifing-block 61 is attached, which blocks face each other and are united by rods 62. To the inner face of each buffing-block the upper end of an arm 63 is secured, which arms are extended in parallel lines diagonally downward and in the direction of the derrick, as shown in Figs. 5 and 6, and beneath the side bars 54 the arms 63 are united by a cross-bar 64. A concavity 65 is preferably produced in each upper end of the buffing-blocks.

IIO

Upon the track of the boom a carriage D is I held to travel, comprising two side pieces 66, united by a bottom piece 67, the top and ends being open. At each end of the carriage truck-wheels 68 are journaled upon suitable axles 69, which wheels are adapted to travel upon the track 55.

In the bottom 67 of the carriage, near the outer end, a rectangular aperture 70 is produced, and at or near the center a preferably triangular opening 71, while a third and smaller opening 72 is made near the inner end, as best illustrated in Fig. 5. Between the inner end .and the opening 72 a grooved pulley 73 is journaled between the sides of the carriage, and upon the bottom, between the rectangular opening and the outer end,a lock-bar 74 is held to slide, provided with an upwardly-extending head at the outer end and an integral post projected downward through the opening 70 in the bottom of the carriage. To the lower end of this post a bar 75 is pivoted, having a longitudinal opening in its outer end, and between lugs 76, projected downward from the outer side pieces of the carriage, a lever-arm 77 is centrally fulcrumed, having acounterbalanced or weighted lower end, the upper end of the said lever being provided with a pin, which pin is held to travel in the slot of the link-bar 75, as shown in Figs. 5 and 6.

Above the lock-bar 74, near its ends, guidebars 78 are secured, and to the inner guidebar one end of a spring 79 is attached, the other end of. which spring is secured to the lock-bar between its center and outer end.

Any approved form of sheave S0 is employed in connection with the carriage, having an upwardly-projecting yoke 81, as illustrated in Fig. 5. The hoisting-rope 82 of the sheave is attached to the bottom of the earl) at the rear of the opening 71, from whence it passes around the pulley in the sheave and thence upward through the opening 72 in the carriage, over the pulley 73, and over two pulleys S3 and Sat, journaled respectively upon the upper or inner end of the boom and one side thereof. From these guide-pulleys the hoist-rope 82 is passed downward to a connection with the drum 26, as shown in Fig. 1. In the inner end of the carriage, between its side pieces, one end of a latch 85 is pivoted, provided at the outer forward extremity with a head 86, adapted to contact with the upper connecting-rod 62 of the butting-blocks, and from the under side of the latch, near the head 86, a lug S7 is downwardly projected, adapted to engage with the head of the lockbar 74, as illustrated in Fig. 5.

The movement of the carriage is adapted to be regulated by a person standing near the hatchway, and to that end a shaft 88 is journaled in suitable bearings upon the boom, as illustrated in Fig. 2, the forward or outer end of said shaft being provided with a sprocketwheel 89, over which an endless chain 89 is passed, of sufficient length to be readily grasped from the deck, and upon the rear or inner end of the shaft 88 a pinion 90 is secured, as shown in Fig. 1, adapted to contact with teeth 91, formed upon one edge of the rod 36, connecting the upper lever 34 with the drum 26, to which drum the hoist-rope is secured. Thus by turning the shaft 88 the crank-arm 31 of the drum 26 is depressed and the said drum thrown in engagement with the spindle friction-wheel 25.

In the operation of the carriagewhen the sheave is in the hatch, for instance-the lock-bar 74 is engaged by the lug S7 of the latch 85, whereby the opening 71 in the carriage is uncovered and the head of the latch contacts with the upper connecting-rod 62 of the buffing-blocks. Thus the carriage is held in a fixed position upon the boom, and when the shaft 88 is revolved to cause the hoist-rope to be wound upon its drum as the sheave 80 with its load is carried upward from the hatch'way the yoke 81 passes upward through the opening 71 of the carriage and contacts with the under side of the latch, forcing it upward out of contact with the connecting-rod 62 and the head of the lock-bar, whereupon the lock-bar, being released, is by the action of the spring 79 forced rearward th rough the yoke of the sheave, the carriage bein g released from the buffing-blocks, and, the sheave being locked in position, further tension upon the rope causes the carriage to travel up the boom, and when the bucket carried by the sheave is brought opposite the chute 52 the contents of the bucket are dumped into the said chute, from whence they fall into the derrick-bucket 39. VVheu said bucket is filled,the operator, stationed upon the platform supported bythe derrick-arms 43, presses downward upon the lever 33, thereby setting the drum 27 in motion and causing the bucket 39 to be elevated, its latch tripped, and the load dumped into the upper chute 50. \Vhen the operator ceases to manipulate the chain 89,the counterpoise-weight 35 of the lever 34: acts to restore the crank-arm of the drum 26 to its normal position, whereupon the carriage is free to travel downward upon the boom, and when the lever 77 contacts with the crossbar 64 of the buffing-blocks it forces the linkbar 75 outward, thereby drawing the lockbar from contact with the yoke of the sheave, and the latch 85 at this moment passing over and contacting with the connecting-rod 62 of the butting-blocks also, by reason of its lugs 87, contacts with the head of the lock-bar, thus holding it in its'open position. The position of the carriage just before contacting with the buffing-blocks is illustrated in Fig. 6, and its position after it has been locked is illustrated in Fig. 5. Near the lower end of the boom at each side a chain is longitudinally stretched, and hooks 91 or their equivalent are attached to the buffing-blocks, adapted for engagement with the chains, whereby the blocks may be shifted upon the boom and yet held in a fixed or rigid position over the hatch.
