PATENT OFFICE.
HENRY c; SWAN, or osHxosH, WISCONSIN.
VEHIcLEIf-SPRING.
SPECIFICATION forming part of Letters Patent No. 377,818, dated February 1 4, 18.88;
Application filed November 14, 1887. Serial No. 255,077. (No model.)
To aZZ whom it may concern:
Be it known that I, HENRY C. SWAN, a citizen of the United States, residing at Oshkosh, in the county of Vinnebago and State of Wisconsin, have invented certain new and useful f Improvements in Vehicle-Springs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the-art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and iigures of reference marked thereon, which form a part of this specificaion.
The special object of the invention is to improve vehicle-springs so that the torsionspringswill not rattle in their bearings and will be securely connected with the equalizing-lever; also, to improve the construction of rock-shafts for vehicles.
Figure 1 of the drawings'is a bottom plan View with a bearing in section; Fig. 2, a vertical cross-section on the dotted line x w of Fig. l; Fig. 3, a section on line y y of Fig. l. and Fig. 4 a detail bottom plan view of the equalizing-lever.
Inthe drawings, A represents the side-bar frame, and B the bottom of the vehicle. The latter has an opening, I), covered by the plate C, through which passes the threaded endy of a headed screw, D, This screw also passes through the box E, in which is held the spiral spring F, surrounding said screw and compressed between the screw-head d and the spring-box E.
G is a nut, which works on the screw, so as to regulate the tension of the screw.
H H are crank rock-shafts shackled at h4 to the side bars, a a., and arranged to turn in the bearings K. These rock-shafts consist of the crank h, round arms h h, and the flat shacklearms h2 h2. After many experiments with various forms I find these the best practically for my purpose, because their action is uniform, while they are strong and durable. I connect the cranks h with the equalizing-lever M, whose T form prevents any lateral motion, by the pivoted hooks L, and this equalizing-lever M is provided with ears mm, across which are placed the pins l. The hooks L l are so swung on the cross-pins Z and between the ears mthat the cranks h when resting in the hooks cannot escape therefrom on account of the said-ears. Therock-shafts H require for their roundarms h a bearing, K, consisting of the bottom concaved cap, k, and
the top concaved base, k', so that the arms h' l h may be laid in the concavity of the base and then be received in the cavity ofy the cap, subsequently placed upon it, and fastened to the base.
In order to take up the Wear on something which can be readily replaced, and which will prevent all rattling, I use the leather or other iiexible packingkl, which is preferably bt not necessarily, in a rectangular form. I first press down the middle of the strip in the con-` cavity of the base k', then place the round arm 71, in it, next fold the ends of the strip over the arm, and, finally, fasten down the cap k on the base k.
In this way the springs K can be quickly and without loss of time placed in the flexible packing,while the latter 7c la', in combination with the rock-shaft arms h h of a vehicle-spring, as and for the purpose specified.
' 2. In avehicle-spring, the combination,with the rock-shaft H, cranked at h, of the hooks L and 'equalizing-lever M, the former pivoted between ears m m of the latter, as' and for the purpose set forth. I
3. In vehicle-springs, the spring L, coiled on a vertical bolt, the box E, placed over said spring, and an equalizing-lever attached to said box to prevent side motion, in the manner set forth.
4. In vehicle-springs, the lever M, having a journaled cross-bar at one end and at the other a box, E, and ears m m, to adaptit to be used as described.
In testimony whereof I affix my signature in loo Y presence of two witnesses. HENRY C. SWAN.
