SOUTH BEND, INDIANA.
SPRING FOR SIDE-BAR VEHICLES.
SPECIFICATION forming part of Letters Patent No. 393,759, dated December 4, 1888.
fierial No. 266,980- (No model.)
To all whom it may concern:
Be it known that l, GEORGE W. HARRIS, a citizen of the United States, residing at South Bend, in the county of St. Joseph, State of Indiana, have invented certain new and useful Improvements in Springs for Side-BarVehicles, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention has relation to springs for vehicles of that class including in their construction side bars, the objects being to procost, decrease the number of shackles and other usual securing devices, and provide a combined semi-elliptical and torsional spring that will prevent forward and side motion or pitching, and while retaining all the elasticityof the bow or semi-elliptical spring will have the direct positive vertical motion of the torsional spring.
Other objects and advantages of the invention will hereinafter appear, and the novel feature will be particularly pointed out in the claims.
- Referring to the drawings, Figure l is a perspective of one end of a side-bar frame provided with a spring constructed in accordance with my invention. Fig. 2 is a detail in plan of a portion of the spring, and Fig. 3 is a side elevation of the same.
Similar letters of reference indicate like parts in all the figures of the drawings.
A A represent the side bars of a runninggear, the front and rear ends of which are connected by the usual bolsters, A to which they are bolted by bolts A. Fig. 1 shows the front end of the gear, and the rear end thereof is but a duplication of that described.
B represents a horn-shaped semi-convolute spring, and it comprises the straight portion B, to which is welded the bearing end plate, B which end is slightly above the plane of the straight portion B. The end-bearing portion B is perforated, as at B and adapted to permit of the passage therethrough of the bolts A connecting the side bars and bolsters, said end plate being interposed between the bars and bolsters. An inverted-U-shaped clip, 0, straddles the side bars near each of their ends, the terminals of said clips depending below and passing through perforated springs B.
lugs or ears B, formed 011 opposite sides of the plate B to which are applied nuts serving to bind those ends of the spring snugly in position against the under surface of the side bars, thus giving the spring two bearing pointsriamely, at their rear ends and forward of the same. Forward of the straight portion. B of the spring the same is curved gradually inwardly and upwardly, as at B above the plane of the portion B, in a somewhat convolute shape, and terminates substantially opposite the point where the curved portion begins. At this curved terminal end is formed an eye or shackle, B, which is disposed in a direction coincident with the straight portion of the spring. One of these springs is mounted at each corner of the frame and opposite each other.
D represents a semi-elliptical or how spring, the center of which is above the plane of the terminals of springs B. The ends of the spring D are bent upwardly, and form, in connection with the eye B of the spring B, a shackle, D. v
The body of the vehicle rests upon the curved raised centers of the spring D, there being one at each end of the frame and connecting the two opposite pairs of torsional By this arrangement all end and side pitching is obviated and the strain equally divided and distributed to each of the springs. The weight is thrown directly over the axle, thus doing away with the straining and bending of the sidebars.
Having described my invention and Us operation, what I claim 1. The side bars,A A,and their front and rear connecting-bolsters, A in combination with the torsional springs B, having the perforated bearing ends B interposed between said bars and bolsters, secured by the bolts A, curved, as at B and with the transverse bowspring D, the ends of which are connected to the springs B, as at D B, sultmtantially as specified.
2. The frame A A A", in combination with the springs B, formed, as described, with the perforated plate B and ears B and having the straight and curved portions B the bolts A and clip 0, and with the connectingspring D, substantially as specified.
3. Thespring B, having the raised bearing 1 In testimony whereof I atlix my signature in presence of two Wil'HGSSCS.
GEORGE \V. HARRIS.
