ByK/,reference more -particularly tof, Figs.-1 an'df2,it will be seen `thattherib .4Lk is laterallyioffset. from the aXisof the pivot v8. Thisis done,1in orderV f that by reversingthe plate 5. upon thelever krl, the distanceof the pivot from the yfillsV Crum,y 2,1 may be varied, 'for adapting the jacky foruse inconnectionwith wheels ofqo f relativelyfsmall and large diameters.

In use, with the lever l horizontal or Vsubas to prevent either the armV 9 or the fasteners 19 from the-load-is raised. Whenever desirable. the
plate. 5 may be reversed, for adapting the jack to wheels and the ylike of ldifferent sizes a and for the lifting the load a greater or 1 Vliable andin every way desirable.
v probably the bestk results may be obtained 2,5 by the several features described and shown,
lesser distance. Furthermore, by varying the position ofthe plate 5, the leverage may be varied .for lifting carsfof dilferent weight.
All features of construction employed are simple.andinexpensive and hence the jack may be. advantageously manufactured and marketed. VRegardless of these characteristi'cs however the device 1s eflicient and re- Since these.V details are preferably followed, but within the scopeof the invention as claimed` considerable latitudeis allowed for making suchv minor vchanges asoccasion may dictate.
I claim: .11 .`Y A jackcomprisng va lever-having its fulcrum vat `one end,` said lever having thrust means, a plate carrying a pivot and having coming in contact with the thrust means offset laterally from the pivotal axis and engageable with the thrust means of said lever, said .plate being reversible to locate said pivot at either of two distances from the fulcrum when the afore- Asaid thrust means are engaged, means for securing said plate to said lever 1n eitherl of its positions, and a lifting-arm mounted on said pivot. l
2. A jack comprising a lever having its fulcrum at one end and provided Vwith a transverse' groove ata point spaced from said end, a plate having at'spaced points a rib and a pivot, said plate being reversible to locate said pivot at either of twodistances from the fulcrum when said rib is received in said groove, means for securing the plate to said lever inl either of its two positions, and alifting-arm mounted on the aforesaid pivot.
3. A jackincluding a 'lifting-arm, a T- sliaped metal plate having its shank secured to one side of said armnear the end thereof, the head of said platebeing'bent laterally onto the end of said arm, the ends of said head being bent into parallel relation to forni ears, and a buing device mounted between said ears to engage the object to be lifted.V
