UNITED STAT-Es PATENT OFFICE.
WILLIAM W. WILLS, 0F JANESVILLE. WISCONSIN.
IMPROVEMENT -IN LEVERAGE.
To all whom it may concern-r Be it known that I, WM. W. WILLS, of the city of Janesville, in the county of Rock and State of Wisconsin, have invented a new and Improved Leverage; and I do hereby declare that the following is a full and exact description thereof, reference beingliad to the annexed drawings, makinga part of this speciiication, in which- Figure l'is a perspective view. Fig. 2 is also a perspective view with the side of the main frame removed- Fig. 3 is a longitudinal vertical section;v Fig. 4 is across vertical section. Fig. 5 is a. vertical section of a thumbscrew, arm i, and sliding bar d.
Ais the main frame. C C are levers. dis a sliding bar. e is a roller pivoted in the end of the'said sliding bar d. fis a connectingrod. G is also a connecting-rod. h is a slot.
Now, as it regards the mechanical arrangement and construction of this invention, I have adopted a common frame without reference to any particular form or design thereof, and to this said frame I attach the said levers C C, as seen in Figs. l, 2, and 3. These are piv-' oted at No. 2. Now, between these said levers I insert the sliding bar d and roller e, which said roller is pivoted at No. 3 in the en d of the said sliding br. The other end of the said bar is attached to the arm i, with a common thumb set-screw, and may be moved to any desired position in a longitudinal direction, sliding in the slot h, and permanently fixed thereby, tightening the said screw.
The connecting-rod f is divided atNo. 4 into two branches or arms, passing around the lower lever, C', and extending t'o the upper lever, (l, to which it is attached, as seen in Fig. 2.
The spring b is permanently attached to the main frame at Nos. 5 andG. The connecting rod G is hinged to the said spring at N o. 7, ex-A tending downward to the lever C', and is attached thereto .at N o. 8,` as seen in- Fig. 2. Now,it is manifest that whereas the said spring b and the said levers C" C are thus bound together by the said connecting-rodG, ifa force or power be appliedto theisaid connecting-rod ,drawing it downward or in the opposite direction to the action of the said spring, the resisting intluence thereot` will be felt,l and a greater'or less resistance isv manifest at the slightest chan gc of the relative position of 'the said roller e; When moved from thev right to thele'i t the resistanceincreases, and vice versa; and what is most singular is, that the tension of the said spring remains the same through all these mutations or changes.
Now, as it regards the peculiar mechanism of this invention, it does not follow that because I have adopted a-peculiar form or design I s'hould confine myself exclusively to it; nor docs it follow that because it is represented in the drawings as occupying anA upright or vertical position I should conine -myselt' to that alone. I do not confine myself to any of these things, nor to any particular or speciiic mechanism.' i
What I claim, and desire to secure `by Letters Patent, is-
'lhe adjustable sliding bar d, and roller e, in' i combination with the counteracting-levers C C, when arranged substantially as described, and operated in the manner specified.
