Specification forming part of Letters Patent 124,704, dated March 19, 1872.
SPECIFICATION. IzAAc VAN KnRsEN, of Kalamazoo, in the countyof Kalamazoo and State of Michi gan, have invented certain Improvements in Wagon-Jacks, of which the following is a specp lifter toits place. The third part of my invention relates to a double pawl-hook with double handles, to keep the lifter in the paWl-bits.
Figure l is a perspective view of the Wagonjaok. Fig. 2 is a section of the lifter, the double joint, and thelever, iu the line Z Z, Fig. 1. Fig. 3 is the lifter with the cross-bolt, seen in the front. F-ig. 4 is a side board,-seen on the inside. l
A, Fig. 1, is thebasis of theWagon-jack, and B is the case, With double iron front C C, with excavations for the lever-bolt D. E is the lifter, which is runningvin the case B, and F is the double paw1hook With double handles. G is the lever, with the 1everbolt D, and H, Fig. 2,
isa section from the lifter E, with four paWlbits Nos. 1, 2, 3, and 4. I is asection from the lever G, connected to the lifter with a double joint, J. Fig. 3 is the lifter E, seen in the front, With the cross-bolt K; and Fig. 4 isthe side board B and the iron front C, seen on the inside. L is the excavation for the double pawl-hook F, and M is a groove for the crossbolt K to keep the lifter to its place.
When the Wagon is to be raised up, the Wagon-jaok is placed under the ax1e-tree, and by pressing down the lever the Wheel is raised up, the double paWl-hook holding` the lifter 'lole handles, all combined, arranged, and constructed as yand for the purpose set forth.
