IMPROVEMENT IN DMNIBUS-SPRINGS.
Specification forming part of Letters Patent No. 34,136, dated January 14, 1862.
To aZZ whom it may concern:
Be it known that I, J. H. DENNIS, of Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful Improvement in Omnibus-Springs; and I do hereby delare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, making part of this specification, and being a perspective view of a portion of the running-gear of an omnibus illustrating my invention.
The nature of this invention consists in an improved construction and combination of springs and supporting-bars, affording ease and quietness of motion and great strength and durability, and likewise reducing the weight and the cost of construction of the class of carriages to which the improvement especially relates.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
A represents the rear axle of an omnibus.
aaare the journals or arms, upon which the wheels turn.
B B are two longitudinal bars, which may be substituted for the customary semi-elliptical springs secured to the axle A.
(J isa bolster secured to and connecting the forward ends of the bars B B.
D D are hangers depending from the rear ends of the bars B B. The said hangers may be threaded at their lower ends and provided with nuts d d, which support springs E E of vulcanized india-rubber, coiled wire or other suitable material. F is a bar perforated near its ends so as to receive and slide freely upon the hangers D D and resting upon the springs E E.
G represents a portion of the bed or body of the coach or planking or frame-Work to support the same.
By setting the nuts d at up or down the tension or rigidity of the springs E E may be regulated as required and the bed may be kept constantly in trim by the same means.
If preferred, the longitudinal bars B B may be of steel or other elastic material, or the customary leaf-springs may be used in their place; but it is found by experience that the compression-springs E E may be made to afford of themselves sufficient elasticity. The said springs E E have the effect to arrest and deaden the sound of the wheels and render the vehicle noiseless and smooth in its motion as compared with those of the class in common use.
If preferred, the hangers D may be attached to the transverse bar F and project upward through the ends of the longitudinal bars B, the springs and nuts being applied above the latter instead of beneath the bars B B, or the springs E E may be adapted for tension instead of compression, and other slight modifications may be made Without departing from the essential principles and objects of the invention.
The front portion of the coach being constructed substantially in the same manner as that above described, with such modifications as the turning-gear, &c., render necessary, a specific description thereof is not required.
Similar hangers or standards D D and springs E E may, if desired, be employed to connect the front bar 0 with the bars B B, stay chains or braces being applied,if necessary, between the said bars B and hangers D to sustain the draft.
Whether the springs are placed at the front or at the back ends of the bars B or at both front and back, I should claim it equally as my invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
Connecting the bed G to the longitudinal bars or springs B B by means of a transverse bar F, springs E E, and hangers D, substantially as and for the purposes explained.
