To all whom it may concern.-

Be it known that I, HENRY RUsTAD, of the town of Lindsay, in the county of Victoria, Province of Ontario, in the Dominion of Canada, have invented certain new and use-.

ful Improvements in Stump-Extractors and I do hereby-declare that the following is a full, clear, and exact description of the same. This invention relates to improvements in stum -extractors, as described in the present speci cation and illustrated in the accompanying drawings,"that form part of the same.

The invention consists, essentially, of bedbeams and the' base of thedevice secured thereto, having an upwardly and rearwardly projecting frame therefrom, a frame secured to the aforesaid frame and superposed above the base,'standards supporting said frame, a frame rotatably supported on said superposed frame, means for rotating said'frame, a drum turning in a suitable bearing .in said base, means supported from said rotatable frame for engaging said drum, 'means for re-. leasmg from engagement the aforesa d means,

a rotatable vertical shaft journaled in said base and extending upwardly through said rotatable frame, means from said shaft for engaging said drum, and means for rotating said shaft.

- said machine, and generally to provide an eflicient machine which shall be cheap to manufacture, strong and durable, and whereby the operation thereof will be greatly simplified.

- In the drawings, Figure 1 is a perspective view of the device, portions thereof being broken away andone of the sweeps removed.

- Fig. 2 is a vertical section through the machine. of the upper portion of the drum and rota- Fig. 3 is a sectional perspective view table frame, showing the clutch mechanism.

Fig. 4 is a plan view of the rotatable frame," showing the means for operating the clutch mechanism. Fig. 5 is a sectional plan through the line AB, Fig. 2.

Like characters of reference indicate corresponding parts in each figure.

Referring to the drawings, a is the base of the machine, having the loo ed-shaped portions 6, through which the ed-beams 0 extend. The bed-beams c are firmly secured in said loops by suitable bolts or lag-screws and are held apart at the outer ends by the cross-bars d, which are rigidly secured thereto by suitable bolts. The base a has a circular boss e centrally located between the loop portions 1), and a central depression f, forming in the center ofsaid base a circular recess or bearing g. The depression f is closed in at the bottom and has a small circular orifice h therethrough centrally located.

' 'i is a circular flange extending downwardly from the bottom of the circular depression art with j is a triangular frame forming the base a and extending rearward y and up wardly therefrom, the arms thereof being.

preferably I-shaped in cross-section. The arm 7c; of the triangular frame j rises vertically from the basea to the rear of the center and above one of the loop portions 1), and the lower arm 1 extends rearwardly from said 4 0 is a block fitting between the arms I and m and abutting the flattened surface n. The block 0 is preferably semicylindrical in form and hasin its outer face horizontal grooves p to receive the anchor-cable g is a vertical slot formed in the back of the block 0, in which the flange nrests, and r isa suitable tap-bolt screwed into said block throu h the flange n and holding the block secure y in place.

It will be seen that the block 0 will be held securely from slipping sidewise from engaigeand t is a similar bracket secured to the inner flange of the arm m preferably in vertical alinement with the bracket 8.

u is a plate or bar vertically arranged in proximity to the face of the-block 0 and has secured .near the ends thereof the pins or bolts 1). The pins 12 extend through suitable orifices in the extending portions of the brackets s and t and are screw-threaded and have suitable nuts screwed thereon.

to represents spiral springs encircling the pins 12 and inserted between the plate a and thebrackets s and t.

The spring held bar a may be adjusted to any distance from the face of the block 0 by means of the nuts on the pins 1), and thus allow any size of cable to rest in the grooves in the said block, but at the same time will prevent the said cable from dropping out of the groove in which it is placed. It will be seen, however, that the cable may be shifted from one groove to another by merely pushing against the plate u and forcing it forward against the springs w in order to allow the cable to slip downwardly or upwardly from one groove to'another.

An anchor-block such as described provides a means of shifting the height of the anchor-cable very quickly and at the same time retains the said anchor-cable in the position in which it is placed should the tension on the machine be released at any time.

I w is a cylindrical frame centrally located above the depressionf in the base a and hav- 'ing' a suitable flange y extending around the lower edge thereof, thereby making the said frame very rigid.

z is a lug or bracket preferably'forming part with the frame :1: and "extending rearwardly therefrom and is rigidly secured to the upper flange of the arm m of the triangular'frame j.

2 is an extension orlug forming part with the flange w and preferably diametrically opposite the extending portion .2.

frame 00, and are supported at thebottom on the cross-bars 7, which rest upon and are firmly secured to the bed-beams c by suitable bolts.

A frame'constructed as described, with the

standards

4 and 6 supporting it, is very rigid and does not allow any springing whatsoever 6o in'the cylindrical frame a; when strain is put upon it.

8 is a drum having a centrally-located hol- .'lowboss or projection 9 extending downwardly from the bottom thereof and fitting within the circular recess 9 in the base a and prevent it from lifting upwardly.

journaled therein. The bottom 10 of the drum 8 rests upon the raised. boss 0 of the base a. The drum 8 is shown with a spiral groove 11 on the outer periphery; but it will be readily understood that a drum with a smooth surface may be used. The drum 8 extends upwardly within the cylindrical frame 90 and has a flange or rib 12 arranged around its periphery below the said frame to The top edge of the drum 8 is enlarged at 13, having a ring of ratchet-teeth 14 on the upper face.

15 is a horizontal swinging frame resting upon the upper edge of the cylindrical frame :0 and having a downwardly-depending flange 16 encircling the outer periphery of the frame 00.

17 is an orifice through the center of the frame 15 and is preferably square.

'18 is a square block which fits the orifice 17 and projects downwardly through the said frame. The block 18 is flanged at the top end and is secured to the top of the frame 15 by suitable bolts passing through said flanges.

The orifice 17 and block 18 are shown square; but it must be understood that any suitable shape of block and orificemight be used that would not depend on the bolts which secure the block to the frame to take any twisting or torsional strain put upon the said block.

and a ring of ratchet-teeth on the outer edge of the under face thereof to engage the ring of teeth 14 on the top of the drum 8. The block 19 fits loosely around the depending portion of the block 18 and is free to move vertically independently of the same.

21 represents a pair of vertical orifices through the block 19 and arranged dia1netrically opposite, said orifices being preferably square.

22 represents cylindrical orifices centrally located above the orifices 21.

23 represents T-headed bolts projecting downwardly through the orifices 24 in the frame 15 and passing through the

orifices

22 and 21, the lower ends being squared and fitting loosely in the

orifices

21, and 25 are suitable nuts secured on the ends of said bolts under said clutch-block. 26 represents spiral springs encircling said bolts, the lower ends tiereof resting in the orifices 22 and the upper ends bearing against the under side of the frame 15. The springs 26 hold the-ratchetteeth of the clutch-block 19 closely in engagement with the ratchet-teeth 14 of said drum.

It will be seen that if the frame 15 is retated in the forward direction the block 18, and consequently the clutch-block 19, will rotate therewith and cause the drum to be ro- IIO ' tated. Should the frame be moved in the springs 26 into the orifices 22.

opposite direction, the sloped surface of the i I ratchet-teeth on the clutch-block 19 will slide upwardly on'the sloped surface of the theyare free-to lift upwardly above the frame 15.

27 and 28 are circular. blocks surrounding the bolts23 and having the upper face thereof formed with double-inclined surfaces 29.

- The heads of the T-headed bolts 23 normally rest at the bottom of these inclined faces and are free 'to move upwardly. The block 27 has an arm30 projecting from one side thereof, preferably close to the bottom, and an arm 31 projecting from the opposite side thereof in line with the arm 30.

33 is an arm similar vto the

arms

30 and 31, but projecting from the block 27 at right anles to the sald arms and having an upright handle portion 34. The block 28 has a-sin 'gle arm 35 projecting therefrom correspond' ing to the arm 30 of the block 27. The

arms

30 and 35 are provided at their outer ends with upright portions formingpivots. 36 is a bar having orifices 37adapted to engage the said upright pivotal portions and has an extending eye portion 37"projecting beyond the arm 35.

38represents sockets forming part with I the horizontal swinging frame 15, in which the sweeps39 are securely fastened.

40 is a bar one end of which passes through the eye portion 37 of the bar 36 and is pivotally secured therein, and the other end extends outwardly from the frame of the mathe said sweep.

chine to a point in proximity to the outer end of the sweep and is pivotally secured in the lower end of a lever 41, which is pivoted on 42 is a barsimilar to the bar 40 and is piv-' otally secured at the inner end to the arm 31 pivoti ally secured in a'pivoted lever at t e outer end of theopposite sweep.

It will be seen, therefore, that the clutchblock19. may be lifted from engagement with the drum 8 from the outer end of either of the sweeps by throwing the lever 41, and through the

rods

40 or 42 and the arrangement of arms connected with the

blocks

27 and 28, previously described, rotate said blocks, and con sequently. lift upwardly-upon the T-headed The sweeps zontal swingin frame 15 by the truss-rods 43,'which are edly secured in the eXtending portions 44 of the said frame and in the outer ends of the sweeps.

inserted between the frame and the nut.

The upper end of the shaft 45 passes through a central cylindrical orifice 47 in the block 18,

and'a washer 48 is placed over the end of said shaft and rests upon the upper surface of the block 18. I j I i 49 is an adjusting-nut which is threaded and screwed onto the upper threaded end of the shaft 45. The frame 15 is consequently held securely in position and cannot lift upwardly from engagement with the frame 00.

50 is ahand wheel also threaded and screwed upon the upper end of the shaft 45 and tightened down against *the

nut

49, and 51 is a lock-nut placed above the hub of said hand-wheel to hold-it securelyin position.

The bottomvend of the hollow boss or projection 9 from the drum'8 has a centrallysquared orifice 52 extending therethrough, and 53 is a nut or squared shoulder iiXe ly secured to or formingpart with the shaft 45 and resting within the saidsquared orifice.

- rotated by hand if the clutch-block 19 is left in engagement with the drum, as the springs etween the 26 will compress and allow the clutch-block to work as aratchet.

The bottom end of the standard 4 has a "pocket-shaped recess 54 formed therein, said pocket-shaped recess being preferably semicylindrical in shape on the interior surface.

55 is a ratchet-dog having a partially cylinidrical body portion 56,- referably of the same radius-as the semicy indrical recess 54 and resting within said recess.

57 is a pin extending upwardly through the frame a and the center of the circular portion-of the dog 55 and holding the said dog securely in position in the recess 54, effectuallypreventing it from falling outward. The forward end of the ratchet-dog 55 is provided with suitable ratchet-teeth 58 to engage the ratchet-teeth 59 on thelower flange of the drum 8.

60 is a tailpiece forming part with the dog 55 and extending outwardly beyond the side of the standard 4. i 1 Y T 61 is a bolt passing through an orifice in one of the flanges of the standard 4 and is secured in the tail portion 60 of the

dog

55, and 62 is a spiral spring encircling the said bolt between the flange of the standard and peripheral surface of the drum 8.

the head of the bolt. The said spring is placed around said bolt in compression and pulls outwardly on the tail of the dog, thus holding the teeth 58 thereof closely in en gagement with the ratchet-teeth 59 of the drum.

63 is a cam-lever pivotally secured to the base a in close proximity to the standard 4, the cam-surface thereof abutting the tail portion 60 of the dog 55. By turning the cam-lever 63 upon its pivot the larger portion of the cam will be turned toward the tail of the dog, and consequently tilt the said dog upon its pivot, and thereby throw the toothed portion 58 out of engagement with the ratchet-teeth 59 of the drum.

It will be understood that all the strain that is to be put upon the cable Which is wound upon the drum will be transferred to the dog 55 should the horses stop pulling, and in order to further support the base of the standard 4 a rib or projecting shoulder 64 is provided, forming part with the base a.

One of the flanges of each of the standards supporting the cylindrical frame a: and the arm 7c have recesses 65 extending therethrough in proximity to the top and bottom thereof.

66 represents upright bars having portions 67 secured to the lower end thereof at right angles thereto and passing through the lower orifices 65 in the said standards.

68 represents eyebolts encircling the upper ends of the bars 66 and suitably secured thereto and passing through the upper orifices 65.

69 represents coiled springs surrounding the portions 67 and the eyebolts 68 between the bar 66 and the flange of the standards and pressing outwardly from said standards. The projecting ortions 67 and the eyebolts 68 have suitab e nuts screwed thereon outsideof said flange.

70 represents rollers rotatably mounted on the rods 66 and in proximity to the outer The rollers 70 are thus spring-heldto their position and form a yielding means for insuring the even winding of the cable on the drum.

71 represents flanges formed 011 the inner side of the loop portions (1 of the frame and preferably in line withthe under edge of the depending flange or ring 4, formed on the base.

72is a plate extending across the under side of the machine and bent upwardly at both ends and lapped against the outer edge of the bars 7 and securely fastened thereto. The plate 72 forms a guard or shield for the under portion of the machine and prevents stones or other obstructions from damaging the said portion and also prevents the machine from digging into the ground when being moved from place to place, effectually preventing loose dirt from getting into the bearing of the drum.

7 3 represents tongues pivotally secured to a bracket 74 at the extreme end of the sweeps 39, the pivotal portion being formed by a plate 7 3, secured to the top and bottom of said tongue through which a suitable l ingbolt may be passed. The forward end of the plate 7 3 is bent upwardly, as shown, to receive suitable whiflietrees to which the horses operating the machine may be harnessed.

75 is a flat bar secured-to the under side of the sweep and having the outer end secured to the stay-

rod

48, and 76 is a hole through said bar intermediate of its length.

77 is a bracket secured on the top of the tongue, having a channel or groove running angularly across the said tongue and a hole through thesides of said bracket.

When it is desired to move the machine, the tongue may be disconnected from the sweep by removing the king-bolt and placing the tongue so that the inner end will engage the bar 75 and the king-bolt be passed through the end and through the hole 76. The tiebar 43 fits into the channel in the bracket 77, and a suitable bolt is passed through the holes in the sides thereof and above said rod, thus supporting the outer end of the tongue and making the tongue and sweep form practically a single guiding-tongue. The whillletrees may be connected to the bar (I by suit able chains and the machine drawn over the ground.

A machine constructed as described is operated in the following manner: A suitable anchor-cable is looped around the anchorblock 0 and secured to a suitable anchoringstump, thereby holding the machine securely to a certain position. The anchor-cable may be quickly adjusted vertically at any time, as previously described. The cable winding on the drum is then drawn out and looped around the stump to be pulled and is provided with suitable means for gripping the said stump. The horses are hitched to the sweeps in the usual manner, and the clutch-block 19 is dropped downwardly by means of the levers 41 and cam-blocks 27 and 28 until the ratchet-teeth of said clutch-block engage the teeth 14 on the top of the drum 8. The springs 26 hold the clutch-block closely in engagement with the drum and insure the said clutch remaining in engagement with said drum. When the horses begin to move,

the horizontal swinging frame 15 is necessarily rotated, and as the said frame is rotated the block 18 and clutch-block 19 are rotated with it, consequently rotating the drum 8. The ratchet-dog 55 is spring-held in engagement with the ratchet-teeth 58 on the bottom end of the drum and should the horses stop pulling at any time the said dog will hold the said drum from rotating backward. The strain put upon said dog will necessarily equal the pull exerted upon the drum by the *each succeeding tooth as the horizontal horses, and the dog must therefore be of very strong construction and also must be well supported. The practice in former. ma

chlnes has been that the ratchet-dog for holding the drum has been placed between the back portion of the frame and the drum, and consequently a double straln was put upon the frame between the anchor and the center drum is the only strain exerted on the portion' of the frame between the center ofthe drum and the anchor-cable. The means for engaging and disengaging the ratchet-dog vis also located in' a position on the frame and standards'rigidly supporting the upper part of the frame, so that the whole is veryrigid and cannot be sprung in any manner. It will therefore be seen that the drum w1ll not be pinched at any time by the action of the horses pulling unevenly on the sweep, and consequently cause the bearing portions of the drum to bind or get out of alinement.

Should the horses balk or back suddenly when the clutch-block 19 is in engagement with the drum, no damage to the mechanism 'will occur, as the clutch-block will liftupwardly freely against the tension of thesprings 26 and merely drop downwardly into swinging frame is turned. In other constructions clutches somewhat similar have been'used; but'the advantages of a springheld clutch over a clutch which is solidly operated are very apparent, as in a clutchoper ated by fixed working parts should the horses back against the machine the clutch and op- 7 four points by means of the spring-held verwith the bed-beams, and the base of the deerating mechanism would be put under great strain and in many instances would break.

' The clutch mechanism may be readily operated from the end of either sweep, or should the operator of the machine be close to the machine he may throw the clutch in or out of gear by means of the handle 3a. The means for raising and lowering the clutch-block 19 I is very positive and hasabsolutely no feature which is liable to get out of order.

The cable in winding upon the drum is held closely in engagement with said drum at tical rollers, which are placed in close proximity tothe drum and necessarily guide the said cable and prevent it from jumping or The construction own and described forms a frame having a rigid back portion lifting from the grooves or from the surface of the drum; but as they are spring-held they are free to move inward or outward, and thus accommodate themselves to any unevenness in the cable, or should any unforeseen accident occur and the cable getlapped the said guiding-rollers will recede against their springs and not be broken.

, The means provided in this machine for winding up loose cable or taking up the slack is very simple, and the operating-wheel, by means of which the center shaft is turned, is high and clear of all obstructions. The operator of the machine may stand up to the machine and grasp the hand-wheel, having perfect freedom of movement in rotating the drum. As the frame of the machine is very rigid and all the parts are held securely to their place, it will be seen that the drum may be rotated very easily by means of the large hand-wheel, as the frame will not be strained in any direction and will not bind.

The movement of the machine from place to; place is accomplished. in a very simple manner. The tongue is merely disconnected from the end of the sweep and connected to the cross-bar and held from swinging sidewise by the bracket 77, which grasps the stay-rod 43. The whiffletrees are suitably secured to the frame of the machine, as reviously 'mentioned, and the whole mac 'ne readily transported from place to place. The shield or mud-guard "71 forms a shoe underneath the frame, and whenthe said machine is being dragged overthe ground the sloped portion of the said plate will rise over the ground, thus preventing the machine from digging into the ground, and consequently keeping the loose earth from getting under the drum and fouling the bearings.
