Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed March 25, 1905. Serial N0- 251,966

To all whom it may concern:

Be it known that I, JUnsoN HAYWARD, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Hoisting and Conveying Apparatus, of which the following is a specification.

This invention relates to hoisting and conveying apparatus, and has particular application to a cable and improved means for hoisting, lowering, opening, and closing a load-carrier, such as a bucket or similar receptacle.

My invention consists of the construction, combination, and arrangement of parts set forth in and falling within the scope of the appended claims.

In the accompanying drawings, wherein I have shown one embodiment of my invention, like characters of reference indicate like parts in all the figures, and while I have shown one preferred embodiment of my invention I wish it to be understood that I do not limit myself to the precise details of construction which for the purpose of illustration I have delineated.-

Figure 1 is a top plan view of an apparatus provided with my improvements. Fig. 2 is a side view of the same. side elevation of my improved hoisting-drum, a portion of the periphery of the drum being broken away to show the location of the band-brake. Fig. 1 is a top plan view of a drum such as shown in Fig. 3. Fig. 5 is a view in side elevation of that part of the friction-drum adapted to carry the closing-line of the bucket, such view showing the location of the friction-surfaces of the clutch mechanism. Fig. 6 is a modification showing another way of holding the closing-line in contact with the surface of the wheel. Fig. 7 is a detail view, in side elevation, of a form of clam-shell bucket in connection with which my invention may be employed. Fig. 8 is a similar view showing the bucket closed.

In the drawings I have shown my invention applied and used in connectionwith what is ordinarily known as a clam-shell bucket, such as is usually employed in dredging or similar operations. As such buckets are now operated it is necessary to provide an extra drum on the engine-that is to say, one drum is required for the holding-line and a second Fig. 3 is a view in separate drum for the bucket-closing line. Wlth my invention, however, I dispense with one of the engme-drums and its connections and provide a means whereby either or both.

the lines of the bucket may be hauled in or paid out, as'required.

Referring now to the accompanying drawings in detail, the letter A indicates a platform of the apparatus, which may be of any suitable or approved character and upon which is mounted a hoisting-engine B of any well-known type.

C is the drum of the hoisting-engine, around which is wound and secured one end of the closing-line 5.

D is a derrick-frame comprising the upright d and the two inclined standards or struts d, such frame being preferably in the Well-known triangular form.

' The hoisting-boom is shown at E and is connected with the apex of the derrick-frame through the medium of the link-bars c e.

The load-carrying receptacle, which in the present case is in the form of a clam-shell bucket, is shown at F and is provided with .two ropes, that at 5 being termed the closing-line and that shown at 6 the holdingline. The holding-line is fastened at one end, as at 7, to the frame of the bucket and passes over a small sheave-wheel 8 at the outer end of the boom, and thence over a second sheave-pulley 9, suspended from the derrick-frame, to the rope-operating drum G, which drum forms the principal feature of my invention.

The bucket herein shown is what is commonly known as the double chain or rope bucket and is shown in detail in Figs. 7 and 8. This bucket comprises the two sections f f, connected by the central shaft 10, upon which is mounted a powerwheel 11, to which wheel is made fast one end 12 of the holding-line 5.

13 represents the operating-chains of the bucket, through the means of which the sections of the bucket are brought together, as is shown in Fig. 8, by winding such chains around small pulleys arranged alongside the power-wheel when such power-wheel is turned or actuated. by the closing-line 12.

14 14 are the connecting-links of the bucket, which secure such sections to the head-block 15. It is to this block 15 that one end of the holding-line 6 is secured, and

such block is provided with a small idler 16, against which the closing-line 5 bears. The closing-line 5 passes from the power-wheel 1 1 up past this idler 16, over a sheave 17 at the end of the boom E, thence over the pulley 18 on the derrick-frame to rope-drum G, and thence back to the engine-drum O, to which it is secured.

In order to operate the closing-line 5 and the holding-line 6 for the purpose of raising and lowering and opening and closing the bucket and to avoid the use of an additional drum for the purpose, I have devised the following mechanism:

G is a hoisting-drum, which may be lo cated at any point adjacent to the engine, and comprises a frame 20, having the side members 21 in which members is journaled the horizontally-disposed drum-shaft 22. Mounted upon-this shaft is the drum, which is in the nature of a two-part friction-drum, such parts being shown at g and g. The part 9, which is relatively longer than the part g, is mounted to turn with and to slide upon the drum-shaft, and in addition to the barrel portion 23, around which is wound the holdingline 6, it is provided with friction-flange 24, having the friction-surface 25 formed with grooves adapted to receive the friction-plates 26 on the face of the part 9. The friction part 9 is of less width than the part 9 and the closing-rope 5 is wrapped around the same, as is shown at 27, such rope then extending back to the engine-drum C, as heretofore described.

H is a band-brake encircling the flange 25 of the drum part g, and the ends of such band are connected to the brake-cam 28 at the points 29 29. The foot-lever, as at 30, is connected to the cam in such manner that by depressing such lever the band may be applied to the periphery of the friction-flange. The part 9 of the drum G is also formed with a second flange 29 at the opposite end of the barrel from the flange 25 and the flange 29 is provided with a circular gear-rack 30, adapted to mesh with the small pinion 31, mounted upon the extension 32 of the support 21, such pinion being actuated through the medium of a small crank 33 for the purpose hereinafter described.

The operation of my improvement is substantially as follows: Assuming the bucket to be closed and to be elevated into the position shown in Fig. 2, if it be desired to oper ate the apparatus for the purpose 'of conveying a load I proceed in the followingmannerz The part g of the drum is thrown 1nto frictional engagement with the part 9 through the medium of the operating-screw 34,which is provided with a lever 35, and with both the sections thus locked they are lowered by the drum C until the bucket is over the material to be conveyed. The band-brake II is then applied to the section G to hold the same against movement, and the two parts of the drum 9 and g are disconnected or shifted out of engagement. The line 5 is then paid off by the drum C of the engine, thus revolving the part 9 until the bucket is opened. Permiting both lines to run loose, the bucket is then lowered into the material, the brake having been removed from the drum-section g for the purpose of allowing the holding-line to run out at the same time with the closingline. In order to close the bucket upon the material, the drum 9, which is now running loose upon its shaft, is turned in the reverse direction by taking up the line 5 on the drum C until the bucket is fully closed, and then the two sections 9 and g are again connected through the medium of the friction device, so that by continuing to haul in with the drum 0 of the engine both the lines will be simultaneously wound about the drums to which their ends are respectively connected until the bucket is elevated to the desired point. Both lines being thus hauled in, to Open the bucket and deposit the load it is only necessary to disconnect the two drum-sections g and g and apply the brake-bandto the section 9 to hold the same stationary and pay out the line 5 with the drum C, which will permit the bucket to be opened by gravity, and the load will be dumped.

In some instances when the bucket is seizing a load the sections of such bucket will close upon opposite sides of a hard or lumpy substance, such as a log or the like, and in order to release the grip of the bucket upon this obstacle it is only necessary to release the friction ofthe drum C to permit the line 5 to slacken slightly, which will cause the sections of the bucket to open to the desired degree, and by turning the pinion 31 by means of the crank 32 the drum-barrel g will be rotated to haul in upon the line 6, and thus the bucket will be elevated sufliciently to clear the obstruction. The operation of closing the bucket by means of the closing-line may then be continued, as described.

In Fig. 6 I have shown a modification of a manner of holding the closing-line 5 in contact with the section g of the hoisting-drum. In such case instead of taking a Wrap entirely around the barrel of the section g, as is shown in Fig. 5, ,I provide a pair of sheaves 36 36, arranged near the lower part of the section, as is shown in Fig. 6, so that the rope 5 may be guided between the same and the drum-section.

The many advantages incident to the construction just described will be readily apparent to those skilled in the art. It will be observed that the holding-line, which is attached to the head-block of the bucket, may be employed for maintaining such bucket in a stationary position when the closing-line is released to permit the opening of the bucket or to close the same in taking a load.

While in the drawings I have shown my improved drum mounted upon the body of the frame adjacent to the engine, it will of course be understood that it will be arranged at any suitable point and may be of any preferred character.
