SPECIFICATION forming'part of Leners Patent N. 612,662, dated octobr le, leesa Y Application tiled Tune 16, 1897. Serial No. 641,664, (No inodel.) t
To all whom it may concern:
Be it known that I, EDWARD DETWILER, a citizen of the United States of Ameriea, re siding at Horton, in the county of Brown and State of Kansas, have invented certain new and useful Improvements in Stump-Extractors, of which the following is a spccication. The object of this invention is to provide an improved stump extractor or puller which is comparatively simple in construction and effective in operation.
My invention resides in the special construetion and arrangement of the parts, as will be hereinafter set forth.
In the accompanying drawings, Figure 1 is a perspective View of a stump-extractor made in accordance with my invention. Fig. 2 is a side elevation, partly in section; and Fie. 3, a horizontal section.
The base 1 is made of a metal plate provided centrally with a shaft step or bearing, in which rests avertical shaft 10, the upper portion of said shaft being seated in a hollow hub 5, formed integral with a pawl-carrying disk 3, which is mounted on the shaft 10 so as to lie immediately above a drum 9,. The drum 9 is provided with the usual grooved face, and one end of the rope, which is at tached in. any suitable manner to the stump to be extracted, is made fast to the lower portion of the drum. The upper portion of the drum has formed therein ratchet-teeth (i, and within the circumferential ratchet teeth, which lie in'a horizontal plane, are recesses or. ratchet-teeth 15 15, with which engage pawls 12, pivoted to the pawl-carryin g dish 3.
The upper portion of the :frame is made up of two plates or sections 4 4.-, which are provided with semicircular recesses to form an aperture, through which passes the hub 5 on the disk 3, and the outer edges are recessed for the reception of pawls 14, which engage with the ratchet-teeth 6 of the drum, so as te hold the drinn against rotation. Thedrum is turned in the usual manner by a sweep which is securely attached to the sweep-head 16, the same having a rectangular socket which engages the rectangular upper end of the hub 5 above the portion thereof which has a bearing between the semieireular recesses in the plates 4L et.
The base-plate l of the frame is preferably formed of `a single 4casting andhas openings g are 4secured to the upper plate by the other end of the rod 7, which not only serve to attach the brace-bars to the upper plate, but also hold the sections of said upper plate together. The ends of the' rods are upset upon the bars, as shown',"or they may be screwthreaded and provided with nuts, either be ing a convenient way of attaching the parts.
1n the construction set forth it will be noted that the inclined bars 13 hold the upper plates on one side of the-dru1n in proper po sition and that the opposite sides of the plates are held in place by the bars or bails 7, and when great strain is brought to bear upon the bars or bails 7 the tendency'of said strain will be to bring on oneside of the drum the upper plates nearer to the base-platc, so that there will be `no liability of the pawls sliph ping or becoming disengaged from the ratchetM teeth. It will also be noted that theouter or locking pawls la, which hold the drum against rotationas to strain imparted thereto by the rope, may be raised by hand and that the inner pawls are carried by the sweep-operated disk 3, so as to engage with recesses in the upper end of the drum.
ln operation the bars or bails are made fast to a fixed object, as a stump, by a rope 13, which may be providedwith a suitable coup^ ling, and ai'ichor-stakes are driven in the ground so as to engage with the projecting ends of the cross-bar 2, so as to hold thedrumn supporting frame in place. The rope which engages with the drum is made fast to `=the IOO upon the drum; but if the area is limited the horse need only make a half-circle about the frame and then turn back, which will impart an intermittent rot-ary movement to the drum. The pawls on the disk move with the sweep, while the pawls 14 hold the drum against rotation.
With the stumpextractorherein shown and described the usual rope take up, stumphooks, and anchors may be employed, as well as pulleyblocks,when it is desired to use the same.
v Having thus described my invention, what I claim as new, and desire to secure by Letters 1. In astumpextractor, adrum having two sets of ratchet-teeth in the upper portion as shown, of pawls pivoted to the upper portion of the drum-supporting frame for engagement with the outer series of ratchetteeth, and pawls carried by a sweep-operated disk for engagement with the inner ratchet-teeth, substantially as shown.
2. In a stumpextractor,a supporting-frame foradrum,oonsisting of abase-plate, a sweepi operated pawl-carrying disk, a pair of plates which engage the hub of said disk, a shaft' upon which the drum turns, said shaft having bearings in the base-plate and sweep-operated pawl-carrying disk, a pair of bails the ends engaging the horizontal base and top plates of the frame, a horizontal bar attached to the base so as to project beyond the same, and inclined brace bars, substantially as shown and for the purpose set forth.
3. In a stump-extractor, the combination with the base and upper plates, rigid bars on one side of the base and upper plates, and on the other side a pair of bails which are looped upon themselves, the bars and bails connecting the base and upper plates together, a sweep-operated ratchet-disk mounted on a Vertical shaft and in engagement with the upper plates of the frame, pawls carried by the sweep-operated ratchet-disk for engagement with the drum, pawls pivoted to the upper plates of the frame for engagement with the outer ratchet-teeth of the drum and a drum provided with the ratchet-teeth hereinbefore mentioned, substantially as shown and for the purpose set forth.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
EDWARD DETWILER.
