UNITED STATES PATENT; OFFICE GEORGE BRISTOL, 01' mm, comm-(moor FLEXIBLE SPRING I'LD Application filed January 27, 1932. Serial 110. 589,086.

The invention is an improvement in spring pads for an ironing machine or for other similar purposes in which the pad is formed with an individual cap and base held apart by a spring, and in which the parts are re- Another object of the invention is to pro vide a cap for spring pads in which the sides and edges are reinforced by engaging flanges.

Another object of the invention is to provide spring pads adapted to be installed on a. curved base.

A further object of the invention is to provide a base for spring pads in which the guide members that hold the cap are made web shaped to prevent bending. 7

'And a still further object of the invention is to provide a flexible spring pad which is selfcontained in an individual unit and oi simple and economic construction.

With these ends in view the invention embodies aspring pad having a cap with downwardly extended flanges, a base with upwardly extended guides forming slide studs in which the flanges of the cap are held, and a spring, resiliently holding the cap from the base Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure l is a view showing the pads as the would appear in use.

* igure 2 is a side elevation of the pad with a portion broken away showing a sectional new.

13" e 3 is a view looking toward the under slde'of the cap.

Figure 4 is a view looking toward the under side of the base.

Figure 5 is a cross section through the base on line 5-5 of Figllilre 4. h d Fi e6isaviewsowingtepa as- In the drawin the pad is shown as it would be made w erein numeral 1 indicates the cap, numeral 2 the base, and numeral 3 the spring.

The cap is made as shown with a flat piece of plate having downwardly extended ends 5 with flanges 6 at the lower ends and in the center of the flanges 6 are projections 7 which correspond with studs on the base 2. At the edges of the ends 5 are diagonal flanges 8 which bend inward as shown in Figure 3 and at the sides of the member 1 are flanges 9 that engage the outer surfaces of the flanges 8. The cap may be provided with perforations l0-which' form steam outlets for the pad.

The base 2 is made with a flat piece of plate having the studs 11 extending upward at the ends and shaped as shown in Figure 4. It will be noted that these studs are formed with a back having diagonal sides which add materially to its strength and make it very strong and durable. At the upper ends of the studs 11 are projections 12 which limit the upward movement of the cap by holding the members 7 that are slidable in the studs 11. The cap is held upward from the base by the spring 3 as shown andwhen pressure is applied to the top of the pad the cap will move downward with the members 7 sliding downward in the studs 11. On the underside of the base 2 are clips 13 which are arranged as shown in Figures 2 and 4 so that the pads may slide on a strip of material 14 as shown in Figure 1. These clips may be of any shape or design, or arranged in any manner, or any other means may be used for holding the pads to the strips. At the edges of the base 2 are projections 15 that engage and hold the edges of the spring to locate and hold the spring in the center of the base. It will be understood that these projections may be of any other shape and formed in any other manner and also that any othermeans may be used for locating and holding the spring.

It will be understood that other changes may be made in the construction without departing from the spirit of the invention. One of which changes may be in the use of other means for reinforcing the cap, another may be inv the use of other means for slid ably holding the cap to the base and still mother may be in the use of ot er means for resiliently holding the cap away from the base.

The construction will be readily understood from the foregoing description. In use the pad may be supplied as shown and assembled on strips as shown in Figure 1 and the strips may be arranged on a flat or curved pad or in any desired position. It will be noted that by holding the cap to the base with the members 7 in the studs 11 the two parts are held at one point and this point is on the center so that greater flexibility of movement will be obtained and the pads may readily be used on a curved surface of any descri tion. The pad may also be used on flat sur aces 'or for any other purpose, and the pads may be held together in any other manner. It will also be noted that by forming the cap 1 with engaging flanges at the sides makes the cap and the ends thereof very strong so that it will stand hard use and wear. It will practically be impossible to bend the ends or legs 5 of the cap so that they will not bind or cause any trouble whatever. The shape of the studs on the base also provides very sturdy construction so that the wearing quality of the pad is materially improved as compared with other pads. To provide a pad in an individual unit and of the sturdy construction shown and described provides considerable advantage and makes it possible to use the pad where it receives very hard service and also makes it applicable for many other purposes.

Having thus fully described the invention what I claim as new and desire to obtain by Letters Patent, is:

1. In a spring pad of the type having a cap and a base slidably attached and held apart by a spring, continuous engaging flanges extending downward from the edges of said cap, the flanges at the ends of said cap having projections extending inward at the centers thereof, flanged studs extending upward from said base with grooves corresponding with the projections of said flanges and stops in the ends of said grooves limiting the movement of said projections said base having spring holding projections at the sides, and clips on the under side of the ends of said base, said attaching means allowing the upper surface of said cap to slope in any direction.

2. In a spring pad of the type having a cap and a base slidably attached and resiliently held apart, means attaching said cap and baseat the transverse center of the ends thereof providing flexibility of movement of one in relation to the other making material 7 having downward flanges, the ends of which engage the diagit possible for the upper surface of the cap to slo e in any direction.

3. 1? spring pad comprising a base with channel shaped studs extending upward at the ends, and in the center of said ends, a cap havingl flanges at the ends with projections on t e flanges cooperating with said studs flexibly holding said cap to the base and a spring between said cap and base, sai holding means providing flexible movement between the cap and base in all directions.

4.
