CUSHION-SPRIN G.
Application filed November 22, 1918. Serial No. 263,678.
To all whom it may concern:
Be it known that 1, JOHN W. FITZGERALD,
a citizen of the United States, residing at Detroit, county of Wayne, State of Michi gan, have invented a new and useful Improvement in Cushion-Springs, of which the following is .a specification.
This invention relates to spring fasteners or centralizers, and has for its object a structure for properly locating the coiled supporting springs of a "spring cushion without actually fastening the coiled supporting springs to the cover. This is accomplished by the arrangement hereinafter de scribed.
In the drawings, 7
Figure l is a plan View of a fragmentary character, showing the cushion embodying my invention.
Fig. 2 shows one of the coiled supporting springs before it has been placed in position in the cushion.
Fig. 3 is a fragmentary section of the cushion showing how the springs are assembled into the cushion.
Fig. 3 is a sectional detail of thecup.
Fig. 4: is a fragmentary plan view of a modified form.
Fig. 5 is a sectional detail showing the spring before it is placed in the cushion;
Fig. 6 is a fragmentary section of the cushion showing how the springs are assembled into the cushion.
Figs. 7 and 8 are details showing how the eye that is struck out of the centralizing cup serves to fasten the tying member to the I casing of the cushion.
In a certain class of spring cushions it has been found desirable to put the springs under an initial compression as several advantages follow the use of this form of construction. It is the object of the present invention to provide members which can engage with one end of the coiled supportmg springs to be utilized in connection with the tying member to bear against the end of the spring to compress it. ltis a further ob- I ject to provide a centralizing member that can be attached to the cover or casing of the cushion to hold the coiled supporting spring in a given position to avoid lateral tipping. To this end I employ centrallzing cups a. These are preferably fiber and have shallow flanges that serve to fit over the outside of the top on bottom 0011 of the coiled supporting spring. The rebound check and dampener Z) is in the form of a stiff coiled spring of smaller diameter that then caused to penetrate tie cover and the fiber Washer, as indicated in the right hand of Fig. 8. This serves to tie the two centralizing members together. It also serves to impale the cups upon the cover. Hence the cups have a fixed relation with the cover and the cups are made to serve as centralizers to prevent the tipping of the springs.
In Figs. 4 to 8 inclusive a modified form is shown. Here the cup is shown with the flange on the inside of the spring instead of on the outside. The centralizing cup in this case is metal and its center is out to form the prongs e that really form a gromet to fasten the cup to the'cover or casing f when they are turned down upon the easing. One prong 9 may beturned over the end of the rebound check, as indicated in Fig. 6, to fasten the ends of the rebound check to the cover f and the cups a.
The employment of a rebound check and dampener in the form of a linear member passing through the coiled supporting spring from end to end is regarded as a separate ,matter of inventionand is claimed in my co-pending application executed of even a coiled supporting spring, a cover for thev cushion, and a cup fitting into the-end of the spring to centralize the spring and fastened to the said cover, the members being Specification of Letters Patent. Patented Mar. 16, 1920.
u may be raised by distendin the spring and p arranged to cause the cup to bear against the end of the spring to compress the same.
2. In a spring cushion, a coiled supporting spring, a cup having a centralizing relation With'respect to the end of the spring, a cover for the cushion and to which the cup is attached, and a tying member for pulling the cup and cover down upon spring to compress the same.
3. In a spring cushion, coiled supporting springs, cushion resting thereon and cups the a plurality of a cover for the each provided in the end of the spring to centralize 10 the spring, the cups being secured to the under side of the cover, the members being arranged to pass the cups to bear against the end of the springs to compress the seine.
In witness whereof I have hereunto set my 15 hand on the 15th day of November, 1918.
JOHN W. FITZGERALD.
