Application filed August 12, 1905, Serial No. 273.963. Renewed July 21. 1906. Serial No. 327,215.

To all whom it may concern:

Be it known that I, ALBERT J ONES DERBY, a citizen of'the United States, and a'resident of-Honolulu, in the Island of Oahu and Territory of Hawaii, have invented a new and Improved Loading Apparatus, of which the following is a full, clear, and exact description.

This invention relates to loading apparatus, and it consists substantially in the detailsof construction and combinations of parts hereinafter more particularly described and pointed out in the claims.

The invention has reference more especially to apparatus for loading sugar-cane and the like in the field for conveyance and trans portation of the same to one or more places or stations, as a sugar factory for instance, and one ofthe principalobjects of the invention is to provide an apparatus of this kind which is simple in its embodiment and comparatively inexpensive to construct or install, besides being timeand labor-saving, effective and reliable in operation, and pos sessing the capacity for long and repeated service.

Afurther' object of the invention is to overcome numerous disadvantages and objections frequently encountered in the use of other apparatus hitherto devised for similar purposes.

The above and additional objects are attained by means substantially such as are illustrated in the accompanying drawings, in which Figurel is a diagrammatic perspective view illustrating the operation of the parts constituting my improvements; Fig. 2 is an enlarged end view of my improved loading apparatus; Fig. 3 is a side view thereof Fig. 4 is a top plan view; Fig. 5 is an enlarged view in detail, to indicate more clearly the construction and organization of the trackways employed in connection with the derrick or frame structure; Fig. 6 is an enlarged top view of the clamp employed upon each of the hoisting cables of the apparatus; and

Fig.7is a side View thereof in part section on the line 77 of Fig. 6.

Before proceeding with a more detailed descriptionlt may be stated that in the form of my improvements herein shown I employ a portable derrick or frame of special construction, the vertical and transverse dimensions of whichare-suflicient to span a car or similar vehicle which is to be loaded with the bundles or sheaves of sugar-cane or the like, said derrick or frame preferably having associated therewith an elevated platforinalso of special construction, on which is located certain of the operative devices of the apparatus, and also on which one or more operatives may stand to control said devices in effecting the proper disposition of the said bundles or sheaves within the said car or other vehicle therefor, all as will presently be explained more fully. The car or other vehicle into which the bundles or sheaves are to be loaded may be of ordinary construction, and the same may be provided with suitable supporting-wheels traveling on rails extending throughout the field in the direction to be followed by the car or else the car may be provided with runners for traversing the ground, it being understood in either case that the car is moved to occupy a position beneath the derrick or frame during the time of the loading of the same.

The derrick or frame is provided at the upper part thereof with a plurality of sets of duplicate reversely-disposed inclined trackways of special construction, upon each set of which is mounted a carrier of special construction, a special binder or sling being also employed for each bundle or sheaf of the sugar-cane or the like to be loaded into the car, by which the said bundle or sheaf when elevated or hoisted to a certain position with reference to the car will be caused to automatically assume a position to enable the stalks of which the same is made u to be disposed within the car parallel with the sides thereof, thus to economize in the amount of space occupied by the stalks within the car, besides providing regularity of disposition of the stalks therein, each of which is a desideratum in loading the stalks directly u on the field, as will be understood. I emp oy herein preferably four sets of the said duplicate reversely-disposed inclined trackways, two sets thereof being dis osed in either direction transversely of the c errick or frame, and combined with each of said two sets thereof is a special embodiment of hoisting cable and anchors and guides therefor, together with specially organized winding and unwinding drums for said cable, by which the bundles or sheaves of sugar-cane or the like may be hoisted from the ground ifnto position to be loaded into the car there- The construction and organization of the parts of the hoisting devices of the apparatus are such that the bundles or sheaves of the material to be loaded will be deposited in any one of a number (eight as herein shown) of places within the car, thus insuring even distribution thereof and quick loading, and while I have herein represented my improve ments in a certain preferred general embodiment, it will be understood of course that I am not limited thereto, in precise detail, as immaterial changes therein may be resorted to coming within the scope of my invention.

Reference being had to the drawings by the designating characters thereon, 1 represents a suitable number of parallellydisposed upright members of a suitable derrick onframe embodied in my improvements,

said members being of the desired height and disposed on opposite sides of parallel rails 2 suitably mounted on the ground and extending in the directions which the car or other vehicle 3 thereof is supposed to travel for transporting the bundles or sheaves of su ar-cane or the like from some part of the fie d in which the same are gathered, to a suitable place or places (not shown), as for instance a sugar factory. Each pair of said upright members 1 are connected or joined together in any suitable way, as by means of one or more cross-braces 4, and similar cross-braces 5' uniting the same at the upper ends thereof, it being here mentioned that each of the parts constituting the derrick or frame is preferably constructed of channelmetal in the form of I-beams, forinstance, as shown. The height of the cross-braces 4 should be amply suflicient to enable the car or other vehicle 3 to pass beneath the same and within the sides of the derrick or frame as will be apparent, and it will be observed that the said derrick or frame, or, rather, the said uprights 1 of which the same is constituted, are preferably mounted at their lower ends upon skids or runners 6, thus to render the entire structure readily portable so as to be carried or moved about from one point of the field in which located, to another, accordingly as may be required in" practice. Other means of portability for the structure may be employed instead of those shown, as will be understood, as for instance, the entire structure may be mounted upon supi portingewheels therefor, as in the manner of the car or other vehicle 3 itself, which is intended to receive or contain the stalks comprised in the bundles or sheaves of sugar cane or the like gathered from the field.

As shown in Figs. 2 and 4, I herein employ four sets of oppositely disposed inclined track'ways 6*, each set comprising duplicate parallel rails 7 occupying an outwardly and downwardly inclined position transversely of the derrick or frame of the structure, and each rail itself being constructed of parallel members 8 and 9 disposed one above the other, and uniting at the outer and lower end of the rail in the form of a sunken or lowered extremity 10, the inner edges of said members 8 and 9 thus'forming practically a recess at the said sunken'or lowered extremity of the rail, the purpose of which will be presently more fully'explained.

There are two sets of the aforesaid trackrails disposed on each side of the derrick or frame as indicated, those of one set alining or corresponding with those of the set opposite thereto, and the rails of the two, sets being disposed at any desired distance apart. The members 8 and 9 of each of the rails of each trackway are connected at or near the upper inner ends or extremities thereof by means of a bolt 11. secured in place by suitable nuts 12 (see Fig. 2) each bolt, being in alinement with the next succeeding one longitudinally of the structure, thus to bring all of them on oneside of the structure substantially in parallelism with those on the opposite side thereof. The said trackways are permanently secured in the desired outwardly and downwardly inclined positions by anysuitable means, and on reference to Fig. 4 it will be observed that the hereinbefore-mentioned cross-braces 5 are connected together at the sides of the derrick or frame by means of longitudinal braces 13 seated and secured upon the upper ends of the parallelly disposed upright members 1, thus to give stability to the structure. Also connect-ing the said cross-braces 5 a suitable distance within the said longitudinal braces 13, are a plurality of other longitudinal braces 14, herein preferably shown as constructed of angle-iron or other metal, and the ends of which are secured to the said cross-braces5 by means of bolts 15, or in any other suitable way. Located centrally of the said. additional longitudinal braces 14 for the structure is still another longitudinal brace 16, which may extend centrally between the sets of parallelly disposed bolts 11 hereinbefore referred to as employed at the inner ends or extremities of the said members 8 and 9 of each rail of each trackway of the several sets of the latter, this embodiment serving to steady the structure, and it being apparent, of course, that the said central longitudinal brace '16 may if desired be also secured to the crossbraces 5, as well as to the upper surfaces of the adjacent members 8 of the rails of the oppositely disposed trackways.

The construction of the parts thus far described has been simply shown herein as illustrative of the general features of my improve ments, and it will be understood that changes therein may be resortedto in actual practice without in any manner departing from the intent or spirit of the invention' Supported and guided between the adj acent.

l edges-of the parallel members 8 and 9 of the railsconstituting eachtrackway referred to, are thesets of wheels 17 and 18, connected together by shafts 19 and 20 extending between the parallel sides 21 of a carrier 22, the pendent extremities 21- of which sides 21 are united by a rod or shaft 24 having thereon a roller 25, it being noted that the said shaft 20 of each carrier is provided centrallythereof witha pulley or sheave 26.

The hereinbefore-mentioned bolts 11 for the rails of each trackway constitute stops by which" the carrier working on the trackway is prevented from being carried upwardly and inwardly transversely of the structure beyond a=certain or predetermined limit, and by referring to Figs.2 and 4 it will be' observed'that the upper surfaces of the members 8 of the rails of the trackways on either side of: the structure are provided with corresponding bearing-plates 27, in which is supported a longitudinally-disposed rotatable rod- 28 rovided, for each set of trackways with wfiich therod is associated, with duplicate fingers 29 normally occupying sub stantially horizontal positions transversely ofthestructure (see Fig. 2), but which may be carried to vertical positions (see dotted linessame figure) by properly turning the rod on which the same are carried, so as to partially rotate the same in the said bearing-plates therefor. As a convenient means of rotating either of the said rods 28, thus to either carry the said fingers thereon to the described horizontal or to the vertical posi tions thereof, 1 provide the same preferably at the inner end thereof with a crank-arm 30, provided at each end thereof with a pendent chain'31 to betaken hold of by the operator for that purpose. The said parallel fingers for each trackway of the duplicate sets thereof disposed on either side of the structure, when carried to the vertical positions thereof just'findicated, constitute stops for the carrier for that trackway, by which the inward and upward movement of the carrier is arrested at a point intermediate the inner extremities of the rails of the trackway and the hereinbefore-mentioned sets of bolts 11 for connecting together the inner ends or extremities of the aforesaid members 8 and 9 of said rails.

As shown in Figs. 2 and 4, the outermost ones of the longitudinal braces 14 for the upper part of the derrick or frame are provided with corresponding sheaves or pulleys 32, while the innermost ones of said braces are also provided with corresponding sheaves or pulleys 33, those of each of the sets referred to being. disposed toward each other and in inclined positions (see Figs. 2 and 4).

As shown in Figs. 3 and 4, the derrick or frame structure of the apparatus has associated therewith a platform 34 located at a suitable height with reference to the sets of trackwaysreferred to, said platform preferably having aladder or stairway 35 leading thereto from the ground, and the same being strengthened in position by means of suitable brace-rods 36v and 37, those of each set preferably crossing each other as indicated, and provided with turnbuckles 38 by which the same may be tightened up or rendered taut. The hereinbefore-mentioned longitudinal braces 13 are of length sufficient to extend the full length of the said platform as shown, as is also the central longitudinal brace 16, and mounted on the platform in suitable position with reference to the other parts of the structure hereinbefore described is a transversely extending shaft 39, 011 which are mounted two sets of winding drums 40 and 41, two of such drums comprising each set. This shaft 39 may be rotated from any suitable driving power, as for instance from a gasolene motor 42 having connection with asupply tank 43, and provided with a shaft 44 having at one end thereof a'pinion 45 engaging with a gear-wheel 46 carried by the corresponding end of the aforesaid shaft. Winding upon one of the drums 40 of the one set is one leg or portion of a cable 47 which passes beneath a guide sheave or pulley 48 on a suitable part of the frame or derrick, and thence extends diagonally across to another guide-sheave or pulley 49 supported by the derrick or frame, from whence this leg 01' portion of the said cable 47 extends longitudinally of the frame or der- .rick to one of the aforesaid sheaves or pulleys 32, thence transversely of the structure and over the hereinbefore-mentioned sheave or pulley 26 of one of the carriers at one side of the structure, thence outwardly any suitable distance laterally of and beyond the structure (see Fig. 1), where it is anchored in any suitable way, as by means of sheaves or pulleys 50 firmly established in position by means of any weighted anchoring device, as for instance one or more bundles of the stalks of sugar-cane or the like which are being gathered in the field. After thus having passed around the sheaves or pulleys 50 of the anchoring devices, the aforesaid cable 47 extends upwardly in the direction of the structure and passes over the sheave or pulley 26 of the corresponding carrier of the set on this side of the structure, thence across and to the sheave or pulley 33 at the opposite side of the structure and over another sheave or pulley 51, thence to still another sheave or pulley 52, and finally to the other winding drum 40 corresponding to the one from which the tracing of the said cable was started. In like manner one leg or portion of the winding cable 53 is wound upon one of the winding drums 41 of the other set of such drums, and extends beneath and over sheaves or pulleys 54 and 55 respectively, from whence this leg or portion of the said winding cable passes over the opposite one of the aforesaid pulleys or sheaves 33, thence transversely of the structure and to and over the guide-sheave or pulley 26 of one of the carriers on the opposite side of the structure, thence to other anchoring sheaves or pulleys 56 and 57 located laterally of and a suitable distance beyond the other side of the structure, and then after passing through these anchoring sheaves 56 and 57 the said winding cable 53 is returned and carried to and over the guide sheave or pulley 26 of the other carrier of the set on. the 'side of the structure now under consideration, thence over the opposite one of the aforesaid sheaves or pulleys 32, thence longitudinally of the structure at 58 (see Fig. 4), and finally over'a guidesheave or pulley 59 on a suitable part of the derrick or frame and under another sheave or pulley 60 also on the derrick or frame, and finally this leg or portion of the said winding cable 53 is wound upon the other drum41 corresponding to that one from which the course of this winding cable was started to be traced.

Intermediate the two winding drums of each set a suitable clutch device 61 (see Fig. 4) is shown to be mounted upon the shaft 39, it being here mentioned that the winding drums are loose upon the said shaft in the intermediate positions of the said clutch devices. By moving the clutch device of either set in one direction one of the winding drums'of that set will be thrown into rotatable operation with the shaft, while the other will be caused to remain idle on the shaft, and thus it will be seen that, for instance, by throwing corresponding drums of the two sets thereof into operative relation with the shaft, one leg or portion of each of the said winding cables thereof will be caused to be wound upon one of the winding drums of a set, while the other leg or portion thereof will be caused to'be unwound or paid out from the other drum of the set, thus imparting a continuous traveling movement to each of the said winding. cables.

Now, on referring to Figs. 1 and 5, it will be noted that during the operations described, a suitable clamp 62, such as shown in Figs. 6 and 7 for instance, is fastened in suitable position upon one leg or portion of each of the winding cables referred to, it having been mentioned that said cables are anchored suitable distances from and laterally of the structure, and the operator in the field on each side of the structure attaches to said clamp 62 abundle or sheaf 64 of canestalks or the like, the stalks of which the said bundle or sheaf is made up being held together by means of abinder or sling 65, which includes a longitudinally disposed block or member 66, around which the duplicate bights 67 of the sling may be wrapped one or more times at 68 (see Fig. 3). The

clamp 62 referred to may be of any preferred construction, but as shown in Figs. 6 and 7 the same comprises a pair of plates 69 having an opening 70 therein for the insertion of a portion of the binder or sling for a bundle or sheaf of the material being loaded, said plates being also provided with a stationary projection 71, having serrations 72 thereon cooperating with corresponding serrations 73 formed on the corresponding face of a movable projection 74, between which two projections a portion of the leg of the winding cable for the bundle or sheaf is securely clampedby means of a cam 75 carried at the end of an operating lever 76 therefor, pivoted at 77 to the said plates 69.

From the foregoing it will be understood that while a bundle or sheaf of cornstalks or the like is being hoisted by one'leg or portion of the cable on each side of-the structure, the other leg or portion of such cable is being correspondingly paid out with reference to the anchoring device for the cable, and it will also be understood that as soon as a bundle or sheaf has been emptied into the car or other vehicle therefor, the clutch devices for the sets of winding drums are, reversed so as to reverse the action of said drums and consequently reverse the operative directions followed by the winding cables, thus, in other words, to cause the other leg or portion of the cable on each side of the structure to be operated to hoist a bundle or sheaf of cornstalks or the like'to the desired elevated position above the car, While the other leg or portion (being the one first referred to) of the cable will be simultaneously paid; out from the other drum in like manner, as explained in the first instance. As. each bundle or sheaf of sugar-cane or the like is elevated to such a position as that the same, or the clamp 62 by'which the same is carried,'is brought into contact with the sheave or' pulley 26 of one of the carriers, said carrier will be moved from the dotted-line position thereof, indicated in Fig. 5, to the full-line position thereof, indicated in said figure, and, if the stop-fingers for this carriage are in the vertical position indicated in dotted lines in Fig. 2, then the carrier will be arrested in such a position as that a bundle or sheaf of material may be deposited within the car or other vehicle ata certain place therein; whereas, if the said stop-fingers are in their horizontal positions, as indicated in full lines in Fig. 2, it is apparent that the upward and inward movement of the carriage will continue until arrested by the hereinbefore-mentioned bolts or stops 11, and thus may the bundle or sheaf of material be deposited within the car at another place therein. In this way it will be seen that accordingly as controlled by the operator or operators, the operation 'of the hoisting devices. may be so carried out as to deposit the bundles orsheaves of material at eight different places within the car, thus insuring economy of space occupied thereby, and deriving a great saving of time and labor in the 5; loading operations generally. When each of the carriers is in its outermost position on the rails of the trackway with which the same is associated, the supporting-wheels 18 therefor are received in the depressions formed at the free extremities of the trackways by the intersections of the members 8 and 9 of the rails thereof respectively, and thus is the pendent frame of the carrier normally maintained in the position indicated in full lines inFig. 2, and also indicated in dotted lines in Fig. 5. But whenever the sheave or pulley 26 of-the carrier is engaged in either of the ways hereinbefore mentioned, the impact caused by the weight of the bundle or sheaf forcesthe carrier upwardly and at the same time carries the sheave or pulley 26 from the dotted-line position in Fig. 5 to the full-line position shown therein, and this action causes the binder or sling of the bundle or 2 5 sheaf to be carried over the roller 24 supported between the ends of the sides 21 of the carrier, thereby causing the bundle or sheaf to assume a position parallel-with the sides of the car, and both facilitating the 30 loading operations as well as preventing undue swinging of the bundle or sheaf, both as willbe apparent.

Having thus described my invention, I- claim as new and desire to secure by Letters 35. Patent:
