Description
tnitrd tapes @than @twine Letters Patent No. 93,48'4, dated August 10, 1869. v
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it ana/y conce/rn:
' Be it known that I, JOHN lF. SEAMAN, of Cortlandville, in the county of Cortland, and State of New York, have invented a new and improved Wagon- Jack; and Ido hereby declare that the following is a full, clear, Aand exact description of the same, reference being had to the accompanying drawings, audto the letters of reference marked thereon, in which-- lFigure 1 is a side viewof my invention.
Figure 2 isa top view of lever B, in which the bevelled shoulder s, at the inner termin-us of the slot D, is clearly shown.
Figure 3 is a bottom view of lever B, in which the cavity or hollowed space o, at the lower side ot' the shoulder s, is shown, being for the purpose hereinafter described..
Similar letters of reference indicate corresponding parts in the three figures. l
The nature of my invention consists in a novel arrangement of the lever B with a bevelled shoulder, s
To enable those skilled in the art to fully under` stand and const-ructmy invention, I will proceed to describe it.
A represents a standard-board, made a littlelonger than the usual space of wagon-axle-treesv from thev ground.
B represents a lever, having in it a slot, D, made of sufficient width and length to fit easily upon the top of the 'standard-board A, as seen in the three iigures. 1
The shoulder s is beve-Hed, as seen in iig. 42, so as to admi-t oi' raising the handle ot' the lever B withoutthrowing the lower bearing of the shoulder. s away from the edge of the standard-board-A.
Under the lever B, at the point where the shoulder s b ears on the notches y, a cavity or space, o, is cut, so that the shoulder rests properly on the notches, (when the leveris in use,) as seen in g. 3.
O represents a step, which is fastened into the outer end of the slot D, being fastened. thereto in a jointed manner, by means of a pin, n, which passes through the two jaws 3 3 of lever B, as shown in figs. 2 and-3.
The step C is made in a triangular shape,l so that being hung at one corner, upon the pin n, it naturally 'from the top of the lever, and a cavity or hollowed" falls against the sides of the standard-boardA, and
.catches upon the notches 4 when the axle is raised.
The standard-board A is madebroad at the bottom, so as toavoid the liability of the axle to fall or tlie jack to tip over when the wagon-wheel is takenoff.
It is tapered to a narrow point at the top, having notches y cut in one side of the standard-board, and notches 4 cut in the other side of the board A, of proper shape lto it'the peculiarly-shaped cavity or space o in the lever, as shown in iig. 3. v The notches 4 are cut so as to tit the bottom of the step C.
At the top of the standard-board A is inserted a pin, my, of suiicient size and length to prevent the lever B from being lifted oli' from the standard-board, when the jack is raised up.
The operationis as follows:
The jack is placed under the axle, having the axle to bear over the step G. l
The shoulder s of the lever B, at the inner point of the slot D, should rest on one of the notches y, at a proper height to raise the 'axle as desired, when the operator bears downward ,upon the handle of the lever which raises 'the axle. The triangular-shapedstep C then falls against and vrests upon one of the notches 4, so as to keep the axle up, that the wheel may be readily removed or'turnedaround, in greasing or painting, as desired.
Ido not claim, broadly, the lever B, but simply its construction and arrangement, as set forth in myeclaim below, as levers of wagon-j acks are old vand well-known neit-her'do I claim making a wagon-jack with notches or catches; nor do I claim constructing a jack with dogs or ratchets, for all the above are Well known; but having -thus described my invention,
What I do claim as new, and-desire to secure by Letters Patent, is-
The construction and arrangement of a wagon-jack, consisting of the lever B, having the' slot D, with a shoulder' bevelled from the.upper side, anda cavity or depression on the under side, at the innerterminus of the slot, the step O, and the tapering double-notched standard-board A, all arranged as and for the purpose set forth."
