i SPECIFICATON forming part of Letters Patent No. 302,227, dated July 22, 1884.

' Application meu December 20,1853. (No model.)

To @ZZ whom, t ina/y concern.-

Beit known that I, Louis Bnnnnrrn, a subject of the Queen of Great Britain and Ireland, and a resident of Crookston, inthe county of Polk, in the State of Minnesota, have invented certain new and useful Improvements in Wagon-Jacks, of which the following specification is a full, clear, and exact description, reference being also had to the accompanying drawings, in which- Figure 1 is a sectional side elevation. 2 is a rear elevation, with the lifting-lever in section, on the line x of Fig. l. Fig. 3 is a plan view in section on the line y g/ of Fig. l. Fig. 4 is a perspective view of one of the lever side plates detached. Fig. 5 is a perspectiveV view, detached, of the adjustable pivot inechanism. Figs. 6, 7 and 8 are perspective views' of the different parts of Fig. 4 detached.

A is the base, in which are secured in an upright position two parallelwooden standards, B B2. These standards are Vsupported by braces O' O2, bolted to the standards at a' a2. The lower ends of each ofthe braces C' O2 are bent around into two eyes, b c, the eyes b adapted to be secured to the top of the corners of the base, and the eyes c adapted to be secured to the sides of the base near its ends by screws, bolts, rivets, or other means. By this means each brace and its eyes are formed in one piece. Cross-tie rods D D2 will be secured in the braces G G2 on opposite sides ofthe standards B' B2,

-to further support them and prevent spreadlng.

E E2 are two sockets or guides, tting in between the standards B B2, and provided with lips d, by which they are held in place between the standards, and connected to each other by a curved arm, E2, having ratchetteeth e, the guides E E2 and arm E3 being cast in one piece.

G J2 are two metal plates, embracing the arm E2, and clamping between their forward ends awooden bar, H', and between their rear ends a hand-lever, H2, the plates G' G2 being securely riveted or bolted to the lever and bar, as shown.

K' isa small met-al "spool7 or cylinder, having disks or rings g upon its ends, and with a bolt or pin, 71.', passing through its center and also through the standards B B2, as shown.

Beneath this cylinder K is an angular strap, K2, attached by its ends to the under side of the bar H', and between the cylinder K' and bar H' is an angular cap, K2, the 4lower side of the cap having a semicireular cavity to fit the upper halt of the cylinder K', and the upper side of the strap K2 being similarly formed to fit the lower side ofthe same cylinder, and the ends of the cap being also formed angular to lt the angles of the strap, as shown. rIhe inside of the angular part .of the strap K2 and the lower' sides of the corresponding parts of the cap K3 are provided with grooves t" and projections i2, which fit into each other and prevent any side movement. The upper part of the cap K3 fits into a cavity formed for it in the lower side of the bar H', whileasmall stud, m, (see Fig. 5,) projects up into the bar H', and still further assists in holding the cap in place. The rings or ribs g project up beyond the edges of the straps K2 and cap K2, and prevent any end movement of the cylinder K'. By this means the bar H' and its connected plates G' G2 and lever H2 are pivoted between the standards B B2 upon the pin h. The cylinder I is provided with a stud, n', projecting down through a slot in the strap K2, and tapped into one end of a swivcl-nut, n2, whose other end is provided with a swiveled rod, n2, pivoted by its lower end in the lower guide, E2, whereby the sockets E' E2 and curved arm E2 are supported in the standards. By turning the nut 91,2, the distances between the cylinder K' and guides E' E2 may be changed, so as to alter the pivotal point of the lever, as hereinafter shown.

M' isa small pawl or dog, pivoted by one end at t between the plates G' G2, and having a hooked lower end adapted to catch below the ratchet-teeth e on the arm E2.

H2 is a small bar, pivoted by one end to the lower rear edge of the pawl M', and passing backward through suitable openings in the rear ends of the plates G' G2, and connected by a rod, M2, to a small hand-lever, h 4, pivoted to the outer end of the lever H2. A coiled spring, M2, is arranged around the bar M2, inside the plates G G2, to hold the pawl M' in contact with the teeth e.- The outer end of the bar H is made slightly hollow and covered with a metal plate, H2, to prevent wear. The

standards B B2 will be provided witha nurnber ,ot' holes, t, through which the pin h may be placed to regulate the height ofthe bar H', to adapt the jack to different kinds of wagons. The pin 71. will be provided with a screwthread and nut, 71?, by which the pin may be held in place. \V lien the jack is to be used, the small lever M is pressed up against the handle of the lever H2, which will, through the rod M" and bar BIP, draw the pawl M backward away from the'teeth c, and enable the lever HL to be raised upward, which will lower the end H. Thepin h is then setinto the proper hole tto bring` the outer end ol' the bar H beneath the axle ol'thc wagon to be raised. rlhe lever H2 is then pressed down until the end H raises the wheel clear ol" the ground, when the pawl M will catch upon the teeth c and hold the lever in that position. Ifnone of the holes t are at the proper point to enable the end H to raise the axle the required distance, then the swivel-nut a may be turned to raise or lower the sockets ll E and arm E, to bring the teeth c at a suitable point with relation to the pawl to cause the latter to support the arin H properly beneath the axle. The rod M3 is attached to the bar M2 by a screw-thread, so that the two parts may be adjusted with relation to each other to eause the spring and other parts to act in concert.-

Having described my invention and set l`ortl1 its ineritsrwhat I claim isl. The combination of the standards l if,

a lever pivoted between said standards, a segmental toothed frame, EEZ E, and means for connecting said lever with said toothed frame, substantially as and for the purpose set forth.

2. The standards B B2, sockets E E2, and curved arin E, formed in one pieee and adapted to be moved up and down between said standards, bar H', plates G G2, lever H2, pawl M', and means for connecting and disconnecting said pawl from said curved arin, substantially as described.

3. The standards B' B2, sockets E El, and curved arni E in one pieee, and adapted to be moved up and down between said standards, a lever pivoted between said standards, means for connecting said lever adjustably to said curved arin, and means for adjustably connecting said lever with said sockets, substantially as shown.

4;. The combination of the base A, standards B B2, braces C C2, and Grossi-ods D' D, substantially as set forth. Y

5. The combination of the standards B B2, sockets E El, curved arni E, bar H, strap K2, cap K, cylinder K, and means for connecting said cylinder adjustably to one ol said sockets, substantially as and for the purpose specified.

In testimony whereof I have hereunto set in y' hand in presence of two subscribing witnesses.
