elastomeric component stem 56 squeezing elastomeric component 42 in a vertical direction this action generates a laterally extending force which is maintained in element 42 by the tubular element 82 of component 46 and compression ring 44 which keep component 42 from expanding inwardly or outwardly by effective u201c squeezing u201d the rotation of component 48 in sleeve 82 is continued until the flange 92 of component 48 engages the lower end 96 of tubular element 82 as best shown in fig4 this end 96 is spaced from the bottom 94 of elastomeric component stem 56 the load applied to elastomeric component 42 can be provided at a selected level by adjusting this spacing accessory 22 is in the illustrated exemplary application of the invention mounted to the riser 28 of bow 20 by threading element 52 of accessory component 48 into a drilled and tapped blind aperture 97 in the riser until the bottom or lower edge 98 of the accessory component element 48 is seated on and frictionally engaged with the front edge 100 of riser 28 fig5 and 6 compare the decay pattern of a bow such as the one illustrated in fig1 without an accessory as disclosed herein fig5 with the decay pattern for the same bow equipped with an accessory of the character identified by reference character 22 it will be apparent to the reader that accessory 22 significantly shortens the decay time of the vibrations set up in the bow when an arrow is released especially those larger and consequently more deleterious vibrations the.
