Specification of Letters Patent.
Patented Jan. 28, 1919.
Application led November 22, 1918. Serial No. 263,679.
To all whom t may concern:
Beit known that I, JOHN W. Frrz GERALD, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a new and useful Improvement in Cushion-Springs, of which the following is a specification.
This invention relates to a spring construction, and has for its object to accomplish the advantages of a so-called pocketed spring, with a large saving in material, and also to provide greater facility for supporting the bottoms of the springs.
In the drawings,-
Figure 1 is a plan view.
Fig. 2 shows the spring before being placed in the bag.
Fig. 3 shows the spring after it has had its top put in the bag.
I-Ieretofore it has been proposed to completely house the springs in so-called pockets to get a free action of the springs without getting the noisy clashings which would follow complete freedom of the springs at the top. These pockets are also desirable to put the spring under initial compression to allow a weaker spring to do substantially the same work which a stiffer spring would do. The stiffer spring would cause a very much greater recoil after a shock, resulting in bouncing the occupant to a greater extent.
I have found that substantially all the ,advantages of a completely pocketed spring can be accomplished by pocketing only the top of the spring. This I accomplish by using a bag a in which the top of the spring or substantially the upper half, may be inserted. The bag is then tied to the spring by placing a cord b around the neck of the bag and around the center of the hour-glass type of spring. With the hour-glass type of spring, as the coils become larger from the middle to the outside, there is no likelihood of the bag slipping ofi".
The base of the spring being open, it may be pinched into the channel strips d which form the supports of the springs. This furnishes greater facility for fastening than is the case where the completely pocketed way.
spring is used. Only the tops of the springs tip because the bottoms are fixed; hence there is practically no chance for clashing of the springs as those portions that have the side movement are completely covered with the bags. Furthermore, the hour-glass form of spring with coils gradually diminishing in diameter from ends to center, tends to expose only the end coils to clashing. Inasmuch as the top is covered with the bag and inasmuch as the bottom is fixed to the channel strips, there is practically no chance of clashing. The entire spring is nclosed in a fabric casing f into which the border wires g are sewed.
Obviousl the use of bags instead of completely inc osed springs effects a saving of almost half the material, which is an important consideration. Inasmuch as a portion of the sprin is under initial compression, a very similar action to that accomplished by a completely pocketed and compressed spring is accomplished. At the same time a part of the spring in the lower half is allowed to function in its normal A variety of actions approximating, if not completely duplicating, the action of the completely pocketed spring may be accomplished by varying the stiness of the spring used.
In the claims when referring to the upper half, I have used this in a descriptive sense for definiteness rather than deiining an exact aliquot part of the spring.
What I claim is:
1. In a spring cushion, the combination of a plurality of springs and pockets of flexible material, a single pocket inclosing only the top of each spring and holding that p ortion of the spring under initial compression.
2. In a spring cushion, the combination of a plurality o springs and a plurality of bags for inclosing only the tops of the springs and holding the top half portions of the springs under initial compression.
3. In a spring cushion, the combination of a plurality of springs of the hour-glass type, and a plurality of fabric bags only inclosing substantially the top half portions pieces of fabric tied each around only the of each spring and tied around the Waist of top portions of a spring and initially comthe springs. pressing the top coils of such spring. l0 4L. In a spring cushion, a plurality of In Witness whereof I have hereunto set 5 coiled springs, base vsupportsV for the gaine myv hand on the lthpday of November, 1918.
fastened to Vopposite sides of the coiled Y springs at the bottom, and a plurality of JOHN W. FITZ GERALD.
