UNITED STATES PATENT OFFER.
GEORGE H. HEBBARD, or SHERBURNE, ASSIGNOR or ONE-HALF TO NATHAN A. BUNDY, OF OXFORD, NEW YORK.
seems FOR ROCKERS.
SPECIFICATION forming part of Letters Patent No. 380,891, dated April 10, 1888.
Applicati n filed December 24, 1387. Serial No. 258,888.
To aZZ whom, it may concern.-
Be it known that I, GEORGE H. HEBBARD, a citizen of the United States, residing at Sherburne, in the county of Chenango and State of New York, have invented certain new and useful Improvements in Springs for Rockers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.
This invention relates to certain new and useful improvements in springs designed for connecting the rockers of chairs or cradles to the stationary base or platform thereof; and theinvention consists in the novel'construction of the spring and the peculiar combinations and arrangement of parts, all as more fully hereinafter described, shown in the drawings, and then specifically defined by the claim.
In the annexed drawings, Figure 1 is a vertical transverse sectional view showing the at tachment of my spring to the rockers and supporting platform or base. Fig. 2 is a detached isometric view of my improved spring.
Referring to the said drawings by letter, A designates the stationary base or platform of a rocking-chair or cradle, and B one of the rockers mounted on said base.
0 represents my improved spring, which is of the form shown in Fig. 2-that is, formed of a single piece of spring metal bent into the form or shape of a double S, with its ends extended parallel with each other and in the same direction. This form of spring has been found from experience to afford a very easy motion, and, owing to its peculiar form, has a very delicate tension, and will allow of the rockers {No model.)
moving to their maximum in either direction without distorting or unduly straining the same, and will at once assume its normal position as soon as the rocking ceases, and the strain is evenly divided throughout the whole length of the spring.
Instead of forming the ends of the spring into eyes or perforating them to receive the securing screws or nails, Iprovide the following means: D are brackets formed with lugs d, the outer faces of which are formed with a channel, 6, Within which rest the ends of the spring, which ends are formed with shoulders f, which bear against the end of the lugs d and prevent displacement of the spring. The brackets are provided with suitable holes, through which pass the screws or other fastening means which secure them to the rocker and base. These brackets serve the additional function of wearing-plates and prevent the lateral movement of the parts wearing or marring the rocker or base, as will be readily understood.
what I claim as new is The combination, with therocker and base, of the brackets D, secured to said rocker and base, respectively, and formed with lugs d, having channels 6, and the spring G, having the shape of the double 8, with its ends seated in said channels and formed with shoulders f, substantially as shown and described.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
GEORGE H. HEBBARD.
