PORTABLE HOIST.

sPEcIFI oA'rIoN forming part of Letters Patent No. 658.810, dated. October 2, 1960.

Application filed April 2, 1900. Serial No. 11,063. (No model.)

To all whom it may concern.-

7 Be it known that I, CYRUS H. SINCLAIR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Portable Hoists,of which the following is a full, clear, and exact specification.

My invention relates more particularly to portable hoists designed for unloading vessels; and it has for its primary object to providea simple and compact portable hoist capable of being readily folded when not in use and as readily set up on the deck of the vessel or other surface where it is to be used and securely held and braced while the cargo is being elevated from the hold and dumped into the lighter or other desired place.

' Another object of my invention is to provide improved andsimple means whereby the inclination of the runway upon which the bucket-carrying trolley travels may be varied at will to suit the varying inclinations of the deck or other surface on which the hoist is supported.

With these ends in view my invention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a vertical longitudinal sectional view of my improved hoist, showing the same supported over the hatchway of a vessel for unloading the same ontothe wharf or pier. Fig. 2 is an enlarged detail sectional view showing the bucket or holder in the act of releasing itself from the trolley. Fig. 2 is an enlarged transverse sectional view of the runway and trolley. Fig. 2 is a detail view of a joint for connecting the standards to a brace-rod hereinafter described. Fig. 3 is a vertical transverse section looking from the left-hand side as viewed in Fig. 1,-and Fig. 4 is a plan view.

I have shown my invention in connection with a boat or vessel for unloading the same as an example of the many uses to which the invention, may be put, this, however, being its greatest field of usefulness at present known to me, owing to the great need of a suitable hoist that may be folded in a compact form and stowed away in the very limited space that could ordinarily be spared on shipboard for an article of this kind.

1 represents a runway or track, which pref erably consists of an I-beam, the lower flanges of which serve as support-s or tracks for the rollers 2 of a trolley 13, whose rollers are journaled on suitable pintles projectinginwardly from side plates 4, arranged on each side of the I-beam 1, as bettershown in Fig. 2. The trolley 3 is provided with a hook 5 or other support by means of which a bucket 6 or other holder for containing or carrying the material to be hoisted from the hold of the vessel and having a bail 7 or other equivalent device may be supported from the trolley when it is desired to convey the bucket to the end of the runway and dump the material overboard and detached from the trolley when it is desired to lower the bucket into the hold to be again filled. The bail 7 may be provided with any suitable detachable device for supporting it upon the book 5. I have shown it provided with a simple link 8, which engages over the hook 5 when the bail is not otherwise supported, but when the bail is lifted above the hook 5 the link 8 will disengage therefrom. The upper end of the bail is attached to a chain or cable 9, which runs over a sheave or pulley 10, supported by a bracket 11 from the under side of the beam 1, the other end of the chain passing around a winch or drum 12, operated by a steam-engine or in any other suitable way.

At or near one end of the beam 1 is secured a pair of inclined standards, which are telescopic or expansible and support the runway upon the deck 13 in such a way that the inclin'ation of the runway may be varied at will to suit the varying inclinations of the deck or other surface on which the apparatus is to be supported. Each of these standards preferably consists of an upper tubular member 14 and a lower telescopic member 15, inserted in the tubularmember 14 and held at the desired adjustment by means of set-screws 16 or other suitable devices. The upper ends of the tubular members 14 are provided with" if etasio 4 perforated ears 17 and the upper side of the runway or beam 1 with a perforated lug 18, and through these ears 17 and the lug 18 passes a removable bolt or pin 19, whereby the runway 1 may not only be rotated or in.- elined with reference to the standards 14 15, but the standards may be readily detached from the runway and folded together therewith in a compact form when it is desired to stow the apparatus away. The lower ends of the members 15 are pointed,so as to dig into the deck and prevent the inclined standards from slipping, and each of the members 14 at or near its lower end is provided with a collar 20, which serves as a support fora perforated lug 21, through which passes a bolt 22, having a hook 23 on its lower end, which passes downwardly through the hatch 24 and engages with the inside of the deck, as clearly shown in Fig. 3, the upper end of the bolt 22 havinga nut 25, whereby the grip of the hook 23 may be tightened and the standards 14 15 thus firmly clamped to the deck and held against both vertical and lateral movement at their lower ends. The upper end of each of the standards 14: is held against oscillation by a pair of guy-rods or cables 26, both secured at their upper ends to a collar 27, adjustably clamped to the tubular member 14 by set-screw 28, while the lower end of each of the guys 26 is hooked to an eyebolt 29, secured in the deck, and is also provided with a turnbuckle 30, wherebythe guy may be tightened.

By the means described it will be seen that one end of the runway may be firmly supported over the hatch and held against undue vibration in all directions. In order to support the other end of the runway, I provide the same with a pair of standards similar to those already described and preferably consisting of tubular members 31, receiving the pointed members 32, clamped therein to the desired adjustment by set-screws '33., while the upper ends of the tubular members 31 are secured to the runway by means similar to that already described with reference to the other standardst0 wit, a perforated lug 34:, formed on or secured to the upper side of the I-beam 1, and perforated sel, if to be used on a ship or Vessel, with the pulley 0r sheave 10 substantially over the hatch and the lower end of the runway projecting over the side of the vessel. The bucket 6 or other holder may then be lowered into the hold and drawn up by hand or by the steam-winch, as described, until the link 8 is at a sufficient elevation to enable an operator who may stand upon a detachable platform 41, secured by suitable collars 42 to the members 1-1 31, to place the link over and in engagement with the hook 5 of the trolley, whereupon, the cable being paid out, the trolley runs down the track or runway and suspends the bucket or holder over the side of the vessel, whence it may be caused to dump in any suitable or well-known way, the lower end of the I-beam 1 being also flanged vertically, as shown at 1, to prevent the trolley from falling off. The bucket dumped, the trolley is drawn back into the upper end of the runway until the upward lift on the bail 7 disengages the link 8 from the hook 5, or, as before explained, such bail may be disengaged from the hook 5 by any of the improved hook devices well known in the art, and when once disengaged the bucket is again lowered into the hold, and so on.

When the device is not needed for use, the standard members may be telescoped one within another, thus reducing their length, and entirely detached from the I-beam 1, as also from the platform 41 and clamp-bolts 22, and the parts thus separated folded lengthwise in a neat and compact bundle.

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