WAGON JACK.
No. 265,179. Patented S pL-ZG, 1882.

DANIEL C. SWETT, OF BETHEL, MAINE.
" WAGON-JACK.
SPECIFICATION forming part of Letters Patent No. 265,179, dated September 26, 1882.
' Application filed July 18, 1882. (No model.) V
To all whom it may concern .1
Be it known that I, DANIEL O. SWETT, of Bethel, in the county of Oxford and State of Maine, have invented certain new and useful Improvements in Wagon-Jacks; and I do hereby declare that. the following is a full, clear, and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification, and in which-.-
Figure 1 is a perspective view of my improved wagon-jack, and Fig. 2 is a side view of the same.
Similar letters of reference indicate corresponding parts in both figures.
My invention has relation to wagon-jacks; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.
1n the accompanying drawings, the letter A represents the base or sill of the jack. B B are the two uprights or standards, at the top of which the stepped lever O is pivoted. The standards B have holes b b for the insertion of the bolt 0, so that the fulcrum of lever G may be raised and lowered to suit wagons of any height of axle. At the other end lever O is pivoted to the arms D D, which again at the lower ends are pivoted to the lifting-lever F by bolt 01. The fulcrum-bolt g passes through the two short uprights G G and through the curved Orin-shaped slot f in lever F. This slot serves to change the fulcrum of lever F 3 5 by allowing it to be moved forward or backward, as it may be desired to move thefulcrnm farther from or nearer to the bolt d. A notched plate,B', is fastened to one of the uprights B, and serves to engage with the free end of 40 the advantages and operation of my invention will be readily understood.
By using the stepped lever 0, connected with the lifting-lever F by arms I) D, I obtain a large leverage without requiring much room or great length of stroke.
Having thus described my invention, I claim and desire to secure by Letters Patent of the United States The combination, in alifting-jack, of the sill or base A, having the posts B B and short uprights G G, stepped lever O, adjustable fulcrum 0, arms D D, and lifting-lever F, slotted atf, andpivoted to the lower end of arms D by bolt 01, the whole constructed and combined to operate substantially in the manner
