ANDREW S. LOVELL, OF UNIONVILLE, CONNECTICUT.
IMPROVEMENT IN WAGON-JACKS.
Specification forming part of Letters Patent No. 132,163, dated October 15, 1872.
To all whom it may concern:
Be it known that 1, ANDREW S. LOVELL, of Unionville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Wagon- Jacks, of which the following is a specification, reference being had to the accompanying drawing, which is a perspective view of any point on the bar if weight is put upon the end of the tongue, such weight causing the tongue to wedge tightly on the bar.
To operate the jack, the tongue is slipped up on the bar till it comes up against the under side of the wagon-axle which is to be lifted; then, by hearing down on the handle, the axle is lifted.
Just above the guide 6 is the cam 13 somewhat loosely pivoted to the standard and lying on the top of the guide when not interfered with. As the bar cl rises, having an axle on the tongue, it will press backward against the cam i and raise its end upward so that it will not prevent the bar d from falling back. There is a notch or shoulder, 61, in the lower end of the bar d, which catches upon the guide 0 and holds the axle suspended when the bar d is raised to that point. To let the axle down again the handle is borne down upon still further and the lever c, striking against the pin h, throws the foot of the bar (I outward so as to disengage the shoulder 61 from the guide 6. \Vhen the foot of the bar at swings outward the cam it falls down upon the guide and prevents the shoulder d from again catching upon the guide 6, so that the bar 61 can slide downward freely and lower the axle which has been suspended.
I claim as my inventionl. The combination of the bar (I, the guide 6 slotted as described, and the cam 13, constructed and operating substantially as described, for the purpose set forth.
2. Also, in a wagon-jack having the parts and operation specified in the last clause, the
pin it so combined with the lever c as to throw the foot of the bar (I outward, substantially as described, and for the purpose set forth.
Witnesses: A. S. LOVELL.
