Specification of Letters Patent.
Patented Feb. 12,1907.
Application filed June 11,1906. Serial No. 321.170.
To all whom it may concern.-
Be it known that I, MIoHEAL' J. BREEN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention,-such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to sulky or gang plows provided with lifting attachments; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed, whereby the plow is raised automatically when it strikes an obstruction without interfering with the action of the lifting attachment.
In the drawings, Figure 1 is a side view of a portion of a plow constructed according to this invention and showing the plow in its lowest position. Fig. 2 is a plan view of the same. Fig. 3 is a side view showing the plow raised automatically by contact with an obstruction and passing over. it. Fig. 4 is a side view similar to Fig. 1, but showing a modification. Fig. 5 is a side view, but shows the low in a raised position with the toggle-links folded upward.
A is a portion of the supporting-frame of a sulky-plow of any approved construction and provided with the usual ground -wheels, which are not shown in the drawings.
B is 'the beam of a plow of any approved construction. This plow-beam is connected to the frame A by means of a bail or arm 0, which is pivoted at its front end to a bracket 0 at the upper part of the plow-beam. The
rear end of the arm C is pivoted to a bracket 7 b on the lower side of the frame A, so that the said arm-is normally arranged in an inclined position.
Dis the liftin -spring, which is arranged between the brac et 0 and a bracket d on the rear part of the frame A.
E is a hand-wheel, and e is a screw for adjusting the tension of the spring D.
F is an arm which is pivoted at one end to the frame A by a pin f.
G and H are a pair of toggle-links pivoted together by a pin 9. The lower link G is pivoted to the plow-beam by a pin 72., and the upper link is pivoted to the arm F by a pint at the free end of the said arm. I is a footlever connected to the upper end portion of the link H. A stop 9' of any approved construction is provided to prevent the said toggle-links from folding downwardly. The arm F projects upwardly and forwardly from its pivot, and the pair of togglelinks when extended are arranged diagonally of the arm C.
K- is the return-spring. spring is secured to the frame A to the rear of t e arm F in the form of the apparatus shown in Figs. 1, 2, and 3, and its front end is se-' cured to a lug k, which projects downwardly from the pivoted end portion of the arm F.
When the parts are in the position shown in Fi 1, the plow can be raised by depressing t e foot-lever. This causes the togglelinks to suddenly fold upwardly, and the low is raised by the lifting-spring D. W en, however, the plow strikes a stone X, as shown in Fig. 1, it is raised automatically to the position shown in Fig. 3, so that it may One end of this pass over the stone without injury.' The diagonally-crossed arm and pair of togglelinks permit the plow to be raised by contact with the stone without the said toggle-links being folded and against the tension of the return-spring K, which is a lighter spring In the modification shown in Fig. 4 thev pivoted arm F is longer than the arm F in Fig. 1, and the return-spring K is connected to the upper end portion of the arm F instead of being connected to a lug on its lower and pivoted end portion. The spring K is also connected to the frame A on the opposite side of the pivot-pin f from the spring K. (Shown in Fig. 1.) This construction is preferred as working more satisfactorily'than the construction shown in Fig. 1; but the action of both of them is the same, the plow being raised by contact with an obstruction and lowered by the return-spring without also immaterial that the to leh. It is s be connected to the frame or to a racket secured to the'frame, as they may be connected to spring may be ofany desired stre any convenient art, which is in turn coilnected with the ame.
What I claim is 1. The combination, with a supportingframe, and a plow-beam; of lifting mechanism provided with foldable to gle-links and pivotallyconnecting the sai I plow-beam with the said frame and permitting the plowbeam to rise and fall without folding the togg-le-links when the plow passes over an obstruction, means for folding the; said togglelinks at will, and a spring which raises the plow-beam when the said toggle-links are folded. a
42. The combination, with a supportingframe, and a plow-beam; of lifting mechanism comprisin an arm, and a pair of togglelinks arranged diagonally of the said arm, said arm and to gle-links being pivotally connected with t e said'frame and-plowbeam and permitting the plow-beam to rise and fall without folding the toggle-links when the plow passes over .an obstruction, means for folding the said toggle-links at will, and a spring which raises the plowbeam when the said toggle-links are folded.
3. The combination, with a supportingframe, and a plow-beam; of an arm pivoted between the said frame and plow-beam, a lifting-sprin for the plow-beam connected to the said ame, apair oftoggle-links arranged diagonally of'the said arm and pivotally connected with the said frame and plowbeam and permitti the plow-beam to rise and fall Without folding the said toggle-links when the plow passes over an obstruction,
means for depressing the said plow-beamlautomatically when t e said toggle-links are not folded, and means for folding the said means for folding the said togglelinks at ill I 1 5. The combination, with a supportingframe, and a plow-beam; of an arm pivoted between the said frame and plow-beam, a lifting-sprin for the plow-beam connected tothe said ame, a pair of toggle-links arranged diagonally of the said arm and pivote at one end to the said plow-beam, an arm having its lower end pivoted to the said frame and having its 11 er end pivoted to the other end of the said toggle-links, a return-spring secured to the upper end portion of thelast said arm and to the said frame in front of the pivot of the last said arm, and llgiiiins' for folding the said toggle-links at In testimony whereof I have affixed my signature in the presence of two witnesses.
