SEAT SPRING.
Application filed Novcmber 11, 1920. Serial No, 423.236.
To all whom it may concern. Be it known that I, BERT ll. BENJAMIN,
a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Seat Springs, of
which the following is a full, clear, and GX- act specification,
Thisinvention relates to a spring, and more particularly to a seat spring which is used in connection with agricultural implements or similar devices. and has for its object to provide a spring oi improved construction whereby the maximum amount or resiliency is derived without atlecting the strength and durability of the same- A further object is to. provide a construct-ion of a seat spring, which permits a graduating resiliency.
A further object is to provide a structure in which the rigidity oi the spring is increased at the desired points.
A still further object is to provide a construction 01' this type oi a seat spring in which the amount of material is onsider: ably reduced without affecting the eiliciency and increasing the resil ency of the same.
These and other objects are attainedby providing a simple and efficient construction hereinafter minutely described and claimed.
1n the accompanying drawings 1 have illustrated one embodiment which my invention may assume in practice. It is to be understood, however, that the form shown herein may be modified without departing" from the spirit of my invention.
Fig. 1 is a top plan view of my improved spring.
Fig. 2 is a side elevational view of the same showing the seat attached at the upper end thereof.
Figs. 3, 4c and 5 are cross sectional views taken on the lines 33, 4+4: and re spectively in Fig. 2.
Heretotore considerable difiiculty has been experienced in making a seat spring of the re uired resiliency and at the same time retain the strength necessary to prevent the breakage of the same. I have overcome this diliiculty by providing a fiat steel cantilever spring 10 of uniform cross section preferably made of high carbon steel and having a longitudinally extending embossed bead 11 tapering from the upper end 12 to the lower end 13. The gradual increase in the width and depth ol the embossed head is clearly shown in Figs. 3, .1- and respec tively. This obviously increases the stifl ness of the spring as the lower end of same is approached; The upper end portion 17 of the spring 10 is bent horizontally with respect to the main portion and is provided with two apertures 14 adapted for adjustably fastening a seat 15 shown in the dotted lines in Fig. 2 and the lower end of the spring is provided with an aperture 16 for fastening the spring to any desired implement. i i
It will be noted from the above description of my improved construction of the seat spring that I have not only overcome the difiiculty of making a seat spring of the desired resiliency and at the same time retained the strength necessary to prevent the breaking of the same but also provided an at the same time increasing the strength, du-
rability and resiliency of the spring.
While I have herein described one embodiment of my invention for the purpose of illustration, it is of course to be understood that the same may be modified without departing from the spirit of my invention.
What I claim and desire to secure by Letters Patent is:
1. A fiatspring of uniform cross section comprising two angularly disposed portions, one of said portions having an embossed bead therein, said bead being of least depth and least width adjacent the angle between the two portions and gradually diverg ng to maximum width and maximum depth adjacent its other end.
2. A flat spring of uniform cross section comprising two angularly disposed portions, one of said portions being relatively longer than the. other and having an embossed bead therein, said head being of least depth and least width adjacent the angle between the two portions and gradually diverging to maximum width and maximum depth adjacent its other end.
3. A fiat spring of uniform cross section comprising two angularly disposed portions, one of said portions being relatively longer than the other and having a gradually diverging, longitudinally extending, embossed bead therein of both varying width and depth.
ated resiliency is imparted to the spring when under stress.
5. A seat spring of uniform cross sectloir comprising a flat portion and a beaded meaeos portion, the two portions being angularly disposed with respect to each other, the bead 1n the one portion being centrally and vlongitudinally arranged, the bead further being relatively wide, shallow and flat at one end and gradually tapering and heroin-- ing rounded, narrower and deeper at its other end whereby a graduated res lieney isimparted to the spring when under stress.
In testimony whereof I my signatnre.
BER-T R. BENJAIVHN.
