'.lnerals, 1, 1 designates wheels with axles 2 'and 3, u on which is mounted the main l frame 4 o the machine, 5 is a pole by which horses ma steer and draw the machine to and from t ic place where it is to be used.

' To the rear end of the frame 4 the mast 7 l is hinged at 6 to fold upon the frame. and rest in the top notch 8 of an A-shaped frame or p crutch 9 at the frontend of the frame. Said i frame 9 has a horizontal arm 10, upon which l the beam 11 rests when folded upon the side of the frame as in Fig. 9.

Upon the main frame is fixed by braces 12, 13, 14, and 15 at a considerable height a se ment 16, which is a portion of a circle wit center at fthe hinge or pivot joint 6 of the mast. T o the mast 1s secured a yokeshaped metal frame 18, (see Figs. 1, 5 and 6), having in ahole and in a vertical slot 21 a -long bolt 19, with a thumlnnut 20 taking taking against the outer side of the segment when the bolt is placed in either of the notches 17 therein, the notch beinfr selected that will keep the mast in vertical position Whether the front and rear supporting the nut 20 then clamps the mast frame 18 to .the segment'. If the ground should hold one mast is adjusted to vertical position laterally by the screws 23, which arev threaded' in n iain frame, and press with their ends upon y 26 secured upon the rear axle 3, said bolster i and timber 4 being pivoted together at the sai u right positionthe mast is further seside braces '27, 27 and the front brace 28', ot' which the latter three are )ivoted to a casting .29 on the mast, and each is provided with a sliding jointformed by cli s 30 having a clamping screw 31 to hohlI t xe overlapping sections of the. brace in the adjusted position. 'The lower end of brace 2S is pivoted at 32 to the main frame; and the braces 27 are adjustably pivoted at 33 to links 34 te revent their slipping outward on the groun where they are pivoted to shoes 35, which by being pivoted will adjust themselves to .the surface of the ground. The mast is st-ill further braced by having pivoted to its lower end a shoe. or ground block 3G. 'lich is adjusted to wheels are `on level or on slopingr ground, and

'of the wheels 1 higher than the other, themetals 24, fixed on the end timber 4 of the against one side of the frame and a hook 22 'metals 25 fixed upon the ends of the bolster middle. by means of a pivot 45 through overlap )ing plates 4G, fixed on thc said parts. InI

cured )y the brace 15. and the two longer beam is folded forwardly as in Fig. 9. Durthe ground b v an adjusting sore-w 37 in a pivoted Clovis 3S, and a slanting brace 39, slidable on 3G and having its upper end loosely held in place h v a metal bracket- 40, engaging the lower end of the bolt. or pintle. 41,i on which the turn-table 42 and its braces 43 are journaled; said bolt, 41 passing through the horizontal arms of a bracket 44 secured en the mast and resisting with its lower arm the bracket 40 on brace 39.

To raise and lower the mast, I mount on the brace 12 a windlags 49 with hand-crank 48, ratchet wheel 47, and pawl 50 engaging the latter; and upon said windlass is wound a rope 51, passing over sheaves .32 and on the segment 16,.:ind fastened at 54 near the top of tne mast7 while between the sheaves 52 and 53 the rope is passed as aloop over a sheave 55 on the frame 1'8, tired on the mast, whereby when the windlass is applied the loop will raise or lower the mast, as will also the upper [fart 51x of the rope when it occupies the s anting position fully shown in The beam 11 has its lower end provided with two arms 56, pivoted by two bolts 57 and 5T", to lugs 58, 59 of the turn-table, the latter lug makes half a turn on a ivot bolt 60 when the bolt `.57X is remove andthe ing the folding ofthe beam the braces 15, 27 and 28 are detached and placed on the main frame while brace 2T folds with the mast..

From the front side of the inas't'extend horizontal arms (i1-62. which serve as joists for a platform G13 on which the operator stands. To the front ends ot' the joists is secured a bridge 64 having depending end-lugs 65 clamped to the side bars of the main frame b v hook-bolts 66 and nuts 6T thereon. Vhen the mast is to he folded 'said nuts are loosened to let the bridge swing downward with the platform and turntable, as shown in Fig. 9.

As best'. show." in Fig. 5, the bridge is formed with an upper and a. lower bar in which is journaled a vertical shaft. 68, `having at its u per end a hand-wheel 69 andV between t ie bridgebars a sprocket wheel T0, engaging an endless linkbelt T1. whif-:hit= passed around the turn-table and engages its sprocket teeth 72. Oi course an)r otherforin of chain may be used and the faces of the turn-table and the wheel TU will then be made accordingly. .Either form of chain or that it should extend entirely around the turn-table, but may have its ends scoured near the normalhr rear edge of the table. it will be observed that. the turn-tablebeing journalcd beyond the mast. has aY large clearing 'l for the mast, and agate piccc T4 (see Fig. VL; pivotcd .-it T5 and screw-fastenedat 76, so thatl the table may bc easily removed from the mast and replaced again.

In Fig. 4 is best shown va loot lever 77,

cable muv be used; and it is not necessary l l l normally held upward b v a spring TS and having a cam T9', which hen the lever is de pressed b v the foot holds by frictional conA tact the wheel 70 and thereby the turu-tablc in amY desired position, so it cannot be turned b v ivind biowing at the beam and thc load raised b v it. Turning now to a considera# tion ot' the .vorking mechanisms and the power operating them, thc dcrrick beam is iliade. in two overlapping sections 1l and il, each of which has eflixed to it a clip-shaped guido T0, loosely embracing the other section. In the inner end of the beam section 11a is secured at 80 the end of a rope or cable S1, which is passed oer a shcave S2 in the outer end of section ll, aud thence to ai windlass S3, mounted upon the inner-end oi said section 11 and is provided with a handwheel S4, ratchet wheel S5 and a springactfuated dog S7 (shown in Figs. 7Y and 5'), engaging the ratchet teeth to hold the beam extended to the ditierent lengths desired. The beam is raised and lowered by having at its outer end a yoke or clevis SS, and attached thereto a running block 89. to which 1s secured one end of a rope or cable`90, passing through a standing block 0l on the mast, thence through the ruiming block, thence through another standing block 92, and thence under a guiding sheave 03 in the mast and to a drum 04, on which itis wound when the operator steps on a foot-lever 96, which by a wire or rod 07 and a bell-crank lever 98, engaging an annular groove '.19 of the hub 100, which` slides and revolves on the shaft of the drum and carries a. friction disk 101,v

adapted to engage the end of the drum 'and turn it, and having a broad-faced pulley 1012. driven b v a belt. 103 from a gasolcne engine 104, or other suitable motor mounted on the platfomn 1125 atthe front end ofthe main frame.

106 is a brake band adapted toibe pulled against the peripherical face of one of the end flanges of the drum, by a wire 107 and a hand-lever 108 mounted on the operators platform 63, so that by using the brake lever the beam and its load may be held elevatedA and lowered slowly by the operator'. ln a metal yoke 11b, bolted on the outer end of the beam, ispivoted to tilt at 109 a fork-frame 111, in which is pivoted at. 112 a fork 1 10 adapted to dig. gather and hold the manure, earth or other heavy matter to be raised b v the hoisting mechanism just described. Said fork-frame is held in normal position by a hook 113, pivoted at 114 to the beam and normally held by a spring 115 engaged with a cross bar 116 of the frame, but becomes disengaged when the operator steps ou a pedal li?. which is attached to the hook b v a chain ls, whose length is easily adjustcd .to that ol the beam by placing the e proper 'link of the chain on to a hook (not shown) on the pedal.

When the hook 1 13 is disengaged the frame 1 1 1 tilts downward to the position shown in dotted lines iu Fig. S, so as to engage tlic matei-nils with which the fork is 'to be filled, the traine is then tilted baclcto engagement with the hook and with the fork i'ilied. The latter tiltingis .lone by the rope 119,having one end iixedat 12() to the mast and the other end passed through ablock 1,21 on the forkfreine and a standing block 122 on the mast, and thence over a slieave 123 in the mast and to a drum 95, which is operated and controlled so exactly the same as above described fo'r drum 94 that a repetition'of the,

description is unnecessary, especially as'the corresponding parts for drum 95 are marked the saine numerals only with an exponent a added. Thus the lever 1Q8- brakes drum 95 and belt 103a drivesit.

To swing the fork frame more fully to the desired lowered position in 8, 'the operator may turn the hand-crank wheel 124 of a windlass 125, mounted on the inast, and thus wind thereon a rope 126, which is guided by l sheave 12T, bloclg 128, sheaves 129 'and 130, and has its outer end formed with two branches, of which the shorter branch 131, is attached to a yoke 134;,pivotcd at 135, and

the longe-r branch 132 is fixed to the junction of the fork 110 and what may be termed the fork handle, 136, audits functionzis to tilt the fork backlafter dumping and also to help the branch 131 to tilt the fork frame,

lt will be observed that the block 128 is mounted on the top end of tle bolt 41 so as to be in the center of the turn-table. In the yoke 134 are -several rollers 137, between which the fork handle is held at di'erent elevations when the yoke is swunr outward by the spring 138, which is secured with one end in the apex of the bracing arch -139 and the other to a pin 140 extending transversely through the bars of the yoke.

A1' 141 is pivoted in the fork frame two piu'ailcl links 142, having slots 143 engaging the pin 140. The result of this construction is that a partial pulling on the rope 126431 will release the handle 143 and allow the load to tilt the fork and dump ont of it, the pin 1411 moving sullieiently in the slots 143 'oithat pui-pose, but further pulling on the rope will brin, r the pin to the innenends of the slots :ind then the fork l'i-anie will tilt if released from hook 113.

1t, will 'be observed that the fork franie is :i i'ery stron;r construction without bein;r heavier than necessary, since itis iliade of l'oui` longitudinal bars 144,145 all converginf.r und secured together ut- 146.- and counrging at the op iosite ends. two and tiio tout-ther. vto l'orin bearings for the pivots Vor ti'iiniiions ol" the fork, und :i1 the spread nidllc por! ion ol' the li'unie the hun: are braced b i.' the :ii'cli 1311. :ind the brui-cs il? :ind 14S. besides the bolts 11111 and 146 pus-sed through the bars and through tubular the bars.

'hen the niachineis to be used for stacking hay, the scooping fork 110 is removed and a larger fork lil-ie 15() in Figs. 10 andv11 substituted, and the arrangement of the props between hoistingr cables slightly modified so as to.

bring the fork higher up than in ordinary loading. This may be accomplished in the following two manners: Firstly, by .removingtheemall fork' 110 and the beam section 11,'and substituting a longer beam section with the'hay fork mounted on it and then pass the hoisting cable as in Figs. 11 and 12,

from the pint'll near thevto of the mast,. through a running block 152, tience through a standing'block 91 on the mast and thence over a.Y guide sheave 153 in the mast, and

vthence to the hoisting drum. 0r, if the ma-A chine is intended for stacking only', the en-` gine may be omitted, andthe. rope 90 given a power-increasing tackle 154, attached to a timber 155 ofthe front end of the main frame, and Yhorses hitched to the rope end 155.v -above described but retaining rthe beam sec- Secondly, by passing the ropes as' tion 11, remove the srnall fork 110 and its frame 111, remove the bolts 157 (seeFigs.

7 and 8), remove the short U-shaped piece i 15S from side grooves 159 in the metal .ioke

11b and substitute and secure by said olts 15a, (see Figs. 10' and 11), the longer U- :sliapied piece 158, to which the arms' 160 of t e hay fork 150 are bolted at 171. Said fork 150 is pivoted at 161 to said arms, and at its rear partis a guard 162, well secured to the tinesY by braces 163,-'and by braces' A164---165 to thetcmgue or handle 166, whichheld downward by a latch 1,67', pivoted at 16S and heldfby a spring` 169 until the chain I 118' ulls itaii ay and allows the' load to tilt the ork and em ty'it. 4To prevent too sudden a duin ling t ie rope 126 is secured at 170 to the for f handle and controlled by the windlass 124, which is shown invFig. 3, where it will also bescen in this connection that thechain 118 and rope 126 are the saine for both forks, and the latch 167 in Fig. 10'is a plain equivalent for the latch or hook 113 in Fig. 3; and that in Fig. 11 as well as in Figs. 3 and 8 vmal position after it is emptied.
