DIG-GING AND LOADING MACHINE.

No. ssasee.

To all whom it mag concern;

Be it known'that l, liars H. NirLsoN, a

citizen of the United States, residing at VVillmar, in the county of Kandiyohi and State of Minnesota, have invented new and useful Di ging and Loading Machines, of which the fol owing is a specification.

This invention relates ,to machines for digging, hoisting and loading earth, manure, ravel and other substances, and also for oading and far stacking hay.

The principal objects are to provide a cheap, simple bgt efficient machine forv said purposes and to so construct the same that it may be drawn by horses or other draft animals and readily operated by said animals when in use, but may also beoperated by an engine or other motive power where such is available. The machine comprises a main frame sup ported on four wheels and a second frame connected thereto and supported on two wheels. On the second frame. is mounted a horsepower which drives the machine proper mounted on the main frame. i

In the accompanying drawings, Figure 1 is a plan or top view of the main frame and the machinery mounted thereon, except the Windlass by which the mast is raised, and certain parts of the upstanding frame. Fig. 2 is a continuation of the right hand endof Fig. 1 andconstitutes a top view of the sec-- ond frame with horse-power,mechamsm and the draft olc for the whole machine. Fig. 3 is a side e evation of Fig. 1. Fig. a is a continuation of Fig. 3 and thus a side elevation of Fig. 2. Fig. 5 is a front or right hand end elevation of Fig. 3 with many parts omitted. Fig. 6 is a rear end. elevation of the machine with many parts omitted and with some mast braces added. Fig. 7 is an enlargement of the left end portion of Fig. 3. Fig. 8 is an enlargement of certain parts near the middle of Fig. 1. Fig. 9 is a detail partly sectional view almost in line with either of the levers 46, 47 in-Fig. 1.

Referring to the drawings by reference numerals, 1, 1 designate wheels with axles 2 and 3 upon which is mounted the main frame l of the machine.

5 is a reach extending from the front axle 2 to the second frame 6 to which it is firmly secured. Said second frame is supported by said reach and by an axle 7 and two wheels 8. The axle 7 swings horizontally on a king Specification of Letters Patent.

bolt 9, passed through it and through the i fifth-wheel 10 and the front bar of'thc frame. 11 is a draft pole attached tothe axle 7 and )rovided with a double-tree 12 to which two orses are hitched for transportation of the machine. After arriving at the place of operation the same'horses are hitched to the tugs 13 (shown in Fig. 2), by which a sweep 14 of the horsepower is operated. Said horsepower is mounted on the. frame 6 and consists mainly of a large gear wheel 15 fixed on a central shaft 16 revolving in a bearing 17 fixed to the frame, and a pinion 18 driven by the large gear. The shaft of the pinion is suitably journaled to the frameand has secured at its lower end a miter gear 19, which drives another miter gear 20. The latter ear is fixed on and drives a shaft 21, which in the drawing is journaled below the reach 5 but may as well be journaled between the two parallel bars of which the reach for purpose of strength is composed. In either case the reach is made and placed as low as possible and the'shaft is concealed or cov- 'ered b it so as to make it as convenicntas possib e for the horses to step over them in 'raveli'ng around the power frame.

The rear end of,the shaft 21 is by means of universal ioints 22, 3 brought upward and connected to a short shaft 24. journaled upon the front end of the main frame and fixed in a bevel gear 25, which drives a bevclrgear 26 and thereby shaft 27, bevel gears 28, 29, shaft 30 and a bevel gear 31 fixed on the latter shaft. The gear 31 drives another bevel-gear 32 which is fixed on ashaft 83 journalcd in bearings 34 across the main frame and may be driven by the horse ower and gearing just described, or bya pul ey 35 fixed on the shaft and adaptedto receive a belt (not shown) from any availablesource of power. I

22? is a sliding joint on the shaft. 21 to allow raising-and, falling of the front wheels of the main frame.

On the shaft 33 is slidin ly keyed one member 36 of a friction clutc Whose othermember 37' is revoluble on the shaft and has affixed to it a sprocket 3S, driving a link belt 39 and thereby a largersprocket 39 fixed on a shaft 40, which is also journaled across th 0 frame and is started by throwing the shdabl ber 37.

43 of the slidable member, and a rod 44 6X- tending from the shifter to a hand-lever 45 placed within convenient reach of the oper ator, who usually stands on the ground Wltl'l olubly mounted 'on a stud 50 a turn-table 51 having a peripheric groove with a j ackcham belt 52 engaged therein. A loop of the chain 1s engaged by a smaller grooved wheel 53,'which is journaled on a stud 54 and has alliXed to it a worm-wheel 55, turned by a worm-screw 56 having at one end fixed a friction pulley 57, adapted to be engaged alternately by one of the friction flanges 58 of a drum 59, which, as best shown in Fig. 9, is keyed to slide on the shaft 33 and is provided in its hub with a groove 60 engaged by the fingers 61 of the lever or shifter 46, so that by holding-said lever in one direction the table will be turned to one side and by holding it in the opposite direction the table will turn the other way, and by holding or leaving the lever between the ends of its stroke the table will stand still, as the flanges of the friction drum cannot then engage the friction pulley.

livotcd at 62 to the stud of the turn-table, to fold forwardly therefrom, is a mast 63, which has a metallic bracket 64 with a ropeguiding sheave 65 and a bolt 66. Said bolt is passed through a segmental slot 67 in a metallic plate 68, which forms the upper end of a permanently 11 )standing frame 69 fixed on the main frame (iis best shown in Figs. 3 and 6). The bolt provided with a nut 70 by which the bracket 64 is firmly secured to the plate after the bolt has been moved to such a position in the slot as will bring the mast into vertical position whetl'ier the ground be level or not.

For the purpose of folding the mast during transportation of the machine and raising it again, the main frame is provided upon its front end with a crutch 71 for the mast to rest on after the derrick beam 72- is swung around and placer thereon, as in dotted lines in Figs. 3 and 5. There is also near the top of the mast fixed one end of a rope 73, which passes forwardly over the sheave 65, thence rearwardly over a sheave 74 on the frame plate 68 and thence down to a Windlass 75 mounted on the frame 69 and having a hand crank 76 turning'the rope-drum of the windlass. t

77 is a pawl engaging a ratchet wheel 78 of the windless to hold it in any position.

It will be understood that the bight of the rope passing over the sheave 65 becomes longer as the mast folds and shorter as tize mast is raised by it; and that whatsoever be its length itsupports the mast in all positions from the time the bolt 66 is removed for fol ing until it is replaced again after the raising of the mast is completed.

In Fig. 6 is shown that the mast is not only braced to the main frame by the upright permanent frame 69, but also by a side brace 79, which is removable in order to allow the derrick beam 7 2 to swing around to the crutch 71 The mast and main frame are firmly braced against side strain and side leaning by long side braces 80, which are extensible by being made in sections having collars 81 with set screws 82 holding the overlapping ends of the sections together. These braces are provided with pivoted shoe pieces 83 to sup ort them on the ground and are prevented from spreading by adjustable links 84 holding them I to the main frame.

The derrick beam 72 is pivotally supported at 85 by two lugs 11 on the turntable, and comprises two parallel members united at the outer ends by metallic parts 86, which carry two rope-guiding'sheaves 87, 88 and a pivotally attached clevis 89. To the latter is attached the running block 90 of a block-andfall having its standing block 91 pivoted at 92 to swing horizontally from the top of the mast, and the fall 93 of the rope passed through: an aperture in the mast, where it is guided by a sheave 94 and passes thence to a rope drum 95, fixed on the shaft 40, whose operating and controlling means have already been described, so it will be understood that by manipulating the clutch lever 45 the derrick beam and its load may be raised and lowered.

At or near the middle of the/beam 72 is fixed upon its upper side an upwardly arched metallic frame 96, from the upper art of which. is pivotally suspended two s eletonpendants or hangers 97, 98, which are connected together by one or more links 99. In the lower end of pendant 97 is trunnioned at 1.90 a shovel 161, which is scoo )-shaped or fork-shaped according to the work it is to do.

The handle portion 10:2 of the scoop engages normally in an aperture in a latch 103 (best shown in Fig. 7), which is pivoted at 194 in the pendant 98 and is normally held upright by a spring 105, but when the scoop is to be tripped so to discharge its load by the weight of same the latch is pulled out of engagement with the scoop by the tripping cord 48, which extends from the latch to the post 49 and is guided on its way by sheaves 106 on the pendant and a guide 107 on the mast;

J The'scoop or fork, asthe case may be, is brought into engaging position with the matter it is to operate on by pulling on the cord or cable 108, which connects the pendant 98 with a Winding drum 169 (see Figs. 1 and 8), which isfixe'd on a shaft, 110 journaled in cases drum, the same as already described about lever 16 and drum 59.

The function of the drum 112 is to load the scoop by forcing it into the material that is to fill it.

This is done by Winding upon the drum the fall part 119 of a cable or rope 120, which is secured at 121 to the bail 122, 1 ivoted at 123 near the scoop, to the pen ant 97. The rope is passed thence over the sheave 87, thence over a sheave 124 in the bail, thence over sheave 88, and thence over a sheave 125 in an aperture in the mast and to said drum. The rope 108 is guided by a sheave 126 in the mast 3 and both of said ropes are guided by side rollers 127 mounted on the mast. Said two ropes 1'08 and 119 being wound in opposite directions on their respective drums, and the drums being of various diameters according to the lengths of the ropes, it will be understood that the one rope is unwound as fast as the other is wound upon the drum, and thus the pendants or scoop-supporting frame and the scoop with itarewpe'rated with ease and precision by manipulation of the lever 47. And when the scoop is thus filled and partly elevated by swinging its supporting frame to an inclined position, as shovn in dotted lines in Fig. 3 it my be further elevated, where so required, by elevating the beam by lever 45. The scoop and beam are then swung sidewise to the duni ing groundor wagon, as the case may be, y the lever 46, and then the tripping rope 48 is pulled. As soon as the scoop 1s emptied it tilts back by its own Weight into position to be engaged by the latch as soon as the tri' ping con; is released.

In Fig. 7 is best shown how the pendant 98 may have several holes 128 for the pivots 129, and 130, so that the pendant may be adjusted upward and thus hold the scoop with its front end in such downwardly tilted position as may be required in excavating in hard ground, and for other purposes.

The frame 96 fixed upon the beamienables the pendants to be longer and thus work to better advantage than if shortened by suspendingthem directly from the beam. 011 the other hand the frame 96 is cheaper than an arrangement by, which the pendants might bemade movable up and down in the beam during operation.

in Fig. 5, 131 is a king bolt on which the horse-power frame to turn to either side cording as the p re 11 and Wheels 8 are op erated.

From the above description it will be seen that my machine is a cheap and complete one for the purposes stated, it carries with it its own horse power ready for operation as soon as the horses have drawn the machine to the place where the work is to be done.
