FRED B. KING, OF ALBION. MICHIGAN.

SPRING.

Specification of Letters Patent.

Patented Feb. 16, 1909.

Application filed June 12, 1908. Serial No. 438.240.

To all whom it may concern:

Be it known that I, FRED B. KING, a citizen of the United States, residing at Albion, in the county of Calhoun and State of Michigan, have invented new and useful Improvements in Springs, of which the following is a specification.

This invention relates to spring cushions of that class primaril intended for use in connection with vehic es but equally applicable to chairs, stools, beds and the like, and the object of the invention is to provide a spring cushion of a comparatively s1mple and cheap construction Whlch embodies novel features whereby the springs may be easily and quickly attached to a frame, and which is provided with an auxiliary spring positioned Within each of the main springs and adapted to serve as a cushion or buffer to prevent jar when the main springs are compressed.

With these and other objects in View the invention resides in the novel construction and arrangement of arts hereinafter fully described and claimedl In the accompanying drawings, Figure 1 is a bottom plan view of a spring cushion constructed in accordance with the present invention. Fi 2 is a sectional View upon the line 22 o Fig. 1. Fig. 3 is a sectional vlew upon the line 3-3 of Fie. 1. Fig. 4 is a detail sectional view upon the line 4-4 of Fig. 3. Fig. 5 is a detail perspective view illustratin the means of connecting the plates the supporting Wires and the spring with the wlres. Flg. 6 is a detail sectional view of a modified form. Fi 7 is a sectional view upon the line 7-7 of ig. 6. Fig. 8 is a sectional view upon the line 8-8 of Fig. 7. y

In the accompanyin drawings, and referring particularly to `igs. 1 to 5 inclusive the numerals 1 and 2 designate the upper and lower edge wires of the cushion. The cushion may be of any desired formation suitable for the purpose for which it is in tended, and the edge wires 1 and 2 are each provided with a plurality of supporting Wires 3. These su porting Wires 3 are arranged in pairs suitably spaced from each other and connected by plates 4. The plates 4 have their ends biurcated, and the with slits, and the tongues 5 arms thus provided are bent around thc supporting wires 3 to effectively retain them in spaced relation with cach other. The plates 4 have their body portions provided rovided by the slits are bent upon themsc ves to form retaining elements adapted for the support of an auxiliary spring or buffer 6. interposed between the topand bottom brace or supporting wires 3 is a plurality of double cone-shaped springs 7. These springs T have their upper convolutions connected with the supportin wires 3 by a tie member 8. This t1e mem er is constructed of :1 sin le strand of suitable Wire, and is ada ted to ridge the bifurcated fingers of the plates 4 and to encircle the convolution of the spring and' to tightly engage the supporting wires 3. By this means 1t will be noted that the spring 7 may be quickly and easily connected with the supporting wire 3. The lower convolution of the s ring 7 may be connected with the sup ortmg wire 3 by an ordinary clip 9, as clear y illustrated in Fig. 2 of the drawings, but it is to be understood that this particular manner of connecting the spring with the supporting wires is not to be used exclusively as various similar means may be eHectively employed.

In Figs. 6 to 8 a slightly modified form of the device is illustrated. In these figures the plate a. has its ends bifurcated similar to the plate 4 and these bifurcated ends are bent to engage' the sup orting wires b. These wires are connected1with the springs c in a manner similar to that described m connection with the other figures of the drawings. The late a is provided with a central embossed) portion d and this embossed portion has its sides slit to provide earse adapted to be bent u on themselves to form securing elements or the cushion spring d'. It is to be understood that the cushion springs 6 and d are positioned within the larger double cone-s rings connecting the top and the bottom o the frame.

Havin thus fully described the invention what is aimed as new is:

In a spring cushion, the combination with a frame comprising upper and lower spaced parallel rods, spiral springs between the upper and lower frames, plates con- 1 In testimony whereof I affix my signature necting the rods, said plates being centrally in presence of two witnesses.

provided with a semi-cylindrical embossed FRED B KING portion, said embossed ortion being slitted to provide tongues an e cushion sprin Witnesses:
