To all whom it may concern: v

Be it known that I, Cnarsrornnn 0. Do- LAN, a citizen of the United States of America, residing at Lockport, inthe'county of Ni agara and State'of New York, have invented new and useful. Improvements in Hoisting and ConveyingMechanisms, of which the following is a specification.

This invention relates to hoisting and con veying mechanisms designed especially for use as a" clam or other dredger, and has for its objects to produce a comparatively simple inexpensive device of this character in which the load may be, readily collected,hoisted, and conveyed from lace to place, one Wherein the carriage wil travel smoothly during the conveying operation, and one in which the load will upon reaching its point of destination be automatically released and deposited. v

A further object of the invention is to provide a device of this character inwhich the carriage-o crating cable serves as a guide upon whic the carriage travels, one wherein the sections of the conve er-bucket will be automatically locked in c osed osition, one wherein the locking member wil be automatically released through the action of the hoisting-cable, and onein which the movable head included in the load-carrying device will be guided in its movements and cushioned at the completion of, the latter;

With these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

. In the accompanying drawings, Figure 1 is a side elevation of a hoisting and conveying mechanis embodying the mvention. Fig. 2 is an enlarged side elevation of the load-receiving device and carriage. Fig. 3 is an enlarged detail view, partly in section, of parts of the load receiving and conveying device. Fig. 4 is an end elevation, on an enlarged scale, of the load receiving and conveying device and showing the bucket in closed position.

Fig. 12 is an enlarged detail view, partly in section, of the latch-operating head. Fi 13 is adetail end view showing a modified To pling device. Fig. l iis a detail side elevation of one-of the grappling members.

Referring to the drawings, 1 and 2 designate a pair of supports, preferably in the form of osts or standards, arranged in spaced re ation at points between which the load is to be conveyed, said standards being braced by guy-ropes 3 and having extended therebetween a horizontal guide element or cable 1, attached in any appropriate manner vertical to the upper ends of the standards and constituting a track or way on which a carriage 5 is arranged for travel.

Arranged adjacent to the standard 1' is a' frame 6, having .jou-rnaled'for rotation there in ahoisting-drum 7 and a carriage-o crating drum 8, connected for rotation one fi orn. the other by means of intermeshing gears 9 and 10, ofwhich the latter is fixed upon a powershaft 1 1, dis osed in axial alinement with the shaft 12 of the gear 10 or its shaft a fixed clutch member rum 8, there being provided on rm of load-grap- 13, adapted for engagement by a companion clutch member or adjacent end of the shaft 12, but keye to and for rotation with the latter. The clutchhead 14 is adapted for movement to engaging or non-engaging position by means of-an op crating-lever 15, pivoted at its inner end to a collar lo'uponthe clu-tch-head and between its ends to the frame, there being attached to the latter a toothed ratchet 17, adapted for engagement by a pawl 18, carried by and for locking the lever in its adjusted position.

The drum 8 is com os'ed of a pair ofportions or sections 19 an 20,having their meeting ends provided with outstanding marginal flanges 21, having a series of spaced perfora tions 22, any one of which may receive a single fastening member or bolt 23, adapted for normally connecting the drum-sections for slmultaneous movement, the sectionilg being positively fixed to and for rotation with t e shaft 12 by means of a spline or feather 24, whilethe section 20 is idly mounted u on the shaft for a purpose which will hereinafter appear. The shaft 12 may be designed for engagement with a ratchetead l4, slidable u on the roo ' for travel around apair of guide-pulleys on the post 1 and extended thence around a guide-pulley 31 at the upper end of est 2, 1o

arranged for travel upon that portion of the ends with journals 42, on each of which is at their lower ends in a slotor-reoess 49, pro- 51, pivotedv int e 'at 32, to the carriage 5, which'latter is,

wheel 26, fixed on the shaft, the shaft of l drum7 being similarly fixed against m'ovement by a pawl 27 and. ratchet 28. i

Attached at one end to the section 20 of drum 8 to be wound thereon is a flexible carriage-operating element or cable 29, arranged i the other end of said cable being attac ed, as

equipped witha pair of-wheels or rollers 33,

cable 29 which extends between the standards and with a second pair of wheels 34, designed to travel on the track or way 4, there being engaged with the section 19 of druTm S and to be wound thereon a second carriageoperatin element or cable 35, led around guide-pu leys 36011 the post 1 and engaged at its other end, as at 37, to the carriage. It is to be noted in this connection that the cables 29 and 35 are attached to be wound in relatively reverse directions upon the druin 8, whereby as one cable is wound the other will be paid out, thus to positivel move the carriage back and forth upon t e track 4, and, further, that the cable 29 serves not only for moving thecarriage, but also'as a guide for the latter in its movements.

Connected to and for engagement with the carriage 5 in a manner hereinafter explained is a load-receiving device 38, in which 39 designates a sliding head or block arranged for travel upon apair of verticalguide elements or rods 40, fixed at their lower ends to a hori- Y zontal cross piece or bar 41, provided at its pivoted a pair of crossed members or levers 43, fixed at their lower ends to the sections 44 of a load-receiving bucket or scoop 45, the levers 43 being pivoted at their upper ends to connecting members or links 46, in turn pivotedto a cross piece or bar 47, .c arrying a pair of vertical guides 48, adapted to bear upon the inner edges of the guide 40 and fixed vided in the bar, there being also fixed in said recess a centrally-dispcsed-pin or keeper 50,

designed for en agement by a movable latch block 39 and serving to detachably connect thelatter and bar. The up- I per free end of the latch 51 is disposed between a pair of pressure members or plungers 52 ,ar-

ranged in a suitable 0 ening or recess in the head and acted upony pressure-springs53 to maintain the latch 1n centered enga ing position, there being provided upon the p unge'r-heads outwardlyextending bearing portions or fingers 54, is osed in uide o enlngs or slots 55 in the side aces of t e hea 39 for guiding the plungers in their movements, the

upper ends of the guide members 48 being sharpened, as'at 56, for ready entrance into the block 39.

' ley 61 on the carriage and latch 51 in the manner and which will be more fully described hereineach spring a terminal Connected with the drum- 7 to be wound thereon is ahoisting element or cable 57, extended around guide-pulle s58 on the post 1, from which it is led around a pulley 59 on the carriage, thence over a pulley 60, journaled in the head-block 39, then up and over a pulhaving its terminal fixedly attached, as at 62, to the block, it being apparent that when the cable is wound upon t will be'hoisted toa positionbeneath the-carriage 5 and for:movement with the latter in its travel upon the guides 4 and 29. Connected in the cable 57 is a short chain-section 63, to one link of which there is fixed a latch-operating member or block 64, designedto contact with the u per end of the ibrthe purpose after.

Provided on the side faces of the block 39- 1s a pair of oppositel ing cars 65, to each 0 66, in turn pivoted, as at 67, to the upper end of a second link 68, the lower end of which is pivoted to an car 69, fixed to the upper outer edge of one of the bucketsections 44, while carried by the links is an engaging member orarm 70, having offset engaging portions or fingers 71 designed for engagement with the links to limit the inward movement of the latter at the pivot 67. It is to be understood in this connection that there are two sets 01' pairs of links 67 68, each of which connects one of the bucket sections with the head 39, whereby the latter will serve, through the medium of the links, for moving said section to open-or closed position.

Disposed upon the lower ends 40 are buffer-sprin s 72, adapted to receive the bar 47 for cus 'onin the parts of the mechanism when the buc et-sections are in open position, as illustrated in Fig. 6, while upon the upper ends of the uide there are fixed buffer-springs 73 to receive and cushion the block 39 when the parts are in dumping disposed and projectof the guides position, as illustrated in Fig. 5. The springs 73 areconnected with their respective guides, preferably by forming on the upper end of loop or coil 74, engaged around a threaded neck 75, formed on the guide and clamped between a pair of lates or washers 76, in turn secured in place y a nut 77, there being formed, in the lower washer a marginal recess 78, through which the upper coil of the spring is passed to engaging position.

In practice the drum 7 is operated from the shaft .11 throu h the medium of the gears 9 and 10 for win ing or unwinding the cable 57 to raise and lower the device 38, the clutchhead 14 being normally shifted to non-engaging position, as illustrated throwing the drum 8 out of action, under e di'um the-load-carrying device 38 in Fig. 1, -forwhich is pivoted a link pivoting axle 67 of the pair of which conditions said drum isfixedagainst eiaaea movement by means of the pawl 25 engaging the ratchet 26. After the bucket 45 has received a load and been hoisted to the position v illustrated in Figs. 2 and 4 for movement with the carr'ia e 5 the pawl 25 is released and the clutchead 14 shifted to engaging position through the whereu on the drum 8 will be operated from the sha 't 11 for winding one of the cables 29 or and unwinding the other, thus causing the carriage to travel along the way 4 to the point at which the load is to be deposited, whereupon the drum 7 is a ain thrown into action for further winding the cable 57 until the member or block 64 contactswith the end of latch 51, whereupon the bar 4'? will be released and slide downward on the guides to the position illustrated in Fig. 5, thus acting, through the medium of the links 46 and levers 43, to move the bucket-sections 44 to open or dischargingposition. Withthe bucket-sections in this position the device is again moved, through themedium of the carriage 5, to the point for receiving another load, and the drum 7 is rotated in the proper direction for unwinding cable 57 whereu on the device 38 will descend until the bud etsections still in open position rest upon the ground, whereuponthe head 39'will continue to descend until the latch 51 engages the keeper and the parts'assume the'position illustrated in Fig. 6. When the cable 57 is again wound, the head 39 will first move up-' ward upon the guide and act, through the medium of the links, for moving the bucket-sec tions to closed position and at the same time for automatically receiving a second load, the previously-described operation being then repeated for conveying the load to and discharging it at the point where it isto be de-" posited. It is to be noted that when the bar 47 is released and descends it will be received u on and cushioned by the springs 72, while t e block39 will in like manner be cushioned by springs 73 during final operation of the cable 57 to actuate the latch, while the latter will be automatically returned to and maintained in engaging position through the medium of the spring-plungers 52, which are guided in their movements through the medium-oi the projecting portions 54, working in the slots 55, as before explained, it may also be mentioned that the guide-sections 48 serve in practice to present an extended bean lug-surface tor the guides 40 during move ment of the bar 4%? and also to effect proper alinement of the latter with the block 39 for insuring accurate engagement of the latch 51 withthe keeper 50. Furthermore, it will be observed that under the peculiar construction of the drum 8 the sections 19 and 20 thereof may be readily disconnectedfor independent rotation in initially winding the camedium of? lever 15,

-with the slidable member,

device with the carriage,

'tively connected with the drum-sections connected the cable 29 is first wound upon the section 20, which is thereafter disconnected by removing the bolt 23 to permit the cable 35 to be in turn wound in a reverse direction u on the drum-section 19, and, furthermore, t at through this construction the cables. may be properly tensioned.

In Figs. 13 and 14 there is illustrated a modified form of load-gra ling device in which the relatively mova l; sections 44, carried and operated by the levers 43, each comprise a cross'piece or bar 79 and teeth or tines 80, this form of grapple especially adapt-- ing the device for use in conveying and load-. ing hay or the like. 7 In other respects the device is identical in construction and operation with that above described.

From the foregoing it is, apparent that I produce a simple inex ensive device which in practice will admirab y perform its functions to the attainment of the ends in View, one in which the load-receiving device Will be properly moved with the carriage for conveying the load from place to lace, and one wherein the bucket-sections will be automatically operati e both for receiving and; discharging the cad, it being understood that ,minor changes in the details herein set forth may be resorted to without departing from the spirit of the invention.

Having thus described the invention, what I claim is 1. In a device of the class described, a loadi'eceiving device comprising a pair of relativel movable sections, a guide, a member 'slida ly mounted upon the guide and o eratively connected with the sections, a ead slidably engaged with the guide, a movable latching member for connecting the head autrack or'way, a and a hoisting-ca the load-receiving said cable being to release the carriage movable thereon ble operatively connecting adapted for actuating the latch slidable member from the head. r
