Description

June 16, 1942. R J B ULT SPRING ARRESTER Filed Sept. 15, 1939 inventor RENE u. BRHULT.

attorney Patented June 16, 1942 SPRING ARRESTER Rene J. Brault, Bristol, Conn., assignor to The -Silex Company, Hartford, Conn., a corporation of Connecticut Application September 15, 1939, Serial No. 295,090

2 Claims. (01. 267-74) This invention relates to spring arresters which are intended to prevent the over-stretching of springs to a point where the coils of the springs will take a permanent set.

An object of this invention, is to provide an arrester which is particularly adapted for use in connection with the springs such as used in cofiee makers of the vacuum type, for fastening the strainer to. the bottom of the upper bowl of said coffee makers, as clearly described in the patent to Frank E. Wolcott, No. 2,054,999, September 22, 193

A further object of the invention is to provide such an arrester which can be generally used on coil springs, which is economical to manufacture and which will not obstruct in the use of said springs.

Further objects of the invention will be clearly understood from the following description and from the accompanying drawing in. which:

Figure 1 is a side view, partly in section, showing an embodiment of the invention in the spring of a strainer fastener.

Figure 2 is an enlarged view of said fastener in contracted position.

Figure 3 is a similar view showing the spring of said fastener in stretched condition and the operation of my improved arrester.

Figure 4 is a plan view on line 4-4 of Figure 2.

As illustrated in the drawing, the numeral 5 denotes the upper bowl of a vacuum type coffee maker which has the usual stem 6 and a strainer plate I that is mounted on the bottom of the bowl and fastened thereto by means of a fastener; the said fastener consisting of a spring 8 having an extension 9, which is secured to the strainer by means of a hook l0, and another extension II with a" hook l2 thereon for connecting the said fastener to the bottom edge of the stem 6. A chain 13 is preferably connected to the hook l2 for stretching the said spring to draw the hook under the said edge.

The present invention provides an arrester in the form of a bar, or rod I I, which, in the embodiment shown, extends through the coils I5 of the spring and preferably has loops l6 that are spacedat a distance lessthan the length at which the spring will take a permanent set and loosely encircle the extensions 9 and H of the spring so as to permit them to slide within the loops. The said extensions are preferably formed integrally with the coils of the spring and extend from the ends of said spring with a sharp bend, as indicated at H, to provide positive stops I8.

When the spring is extended to the length permitted by the arrester, as illustrated in Figure 3, the said stops will engage the loops l6 and thereby prevent the extension of the spring to a length-wherein it will take a permanent set.

I claim:

1. For a spring comprising a plurality of coils and extensions at each end thereof, an arrester including a bar extending through said coils, and loops at the ends of said bar slidably encircling the said extensions for permitting the stretching of said spring to a pre-determined extent.

2. The combination of a spring comprising a plurality of coils having an extension projecting from a substantially sharp bend forming a-stop in each of the end coils thereof, a bar extending parallel to the axis of said spring, and a loop at each end of said bar for slidably connecting the same to said extensions and engaging said stops to prevent the stretching of said spring to a point beyond its limit of resiliency.
