SPRING-macon. GRIP.
Patented July 3, 1917.
"Figa 6 is a fragmenta view through a through a recoil modified fo at Los certain grip, being shown. Spring The spring recoil grip mechanism form--` ng is a 111g the subyect matter of the present inven-"' -tion is designed to afford a simple and very The said 4 friction fiber, automobile frictionmaterial piece 14 may be made of brake lining or any other which will prevent the sh easily, when the parts are under a gripping strain. The said shoe or gripping platevllis carried by a pivot bolt 15 which passes` through the bearing 12 and at its ends asses through apertures in the ends of lin 16 and 17. The said shoe 11 is preferably inade a little wider than the leaves of the oe from slipping spring so that when the pivot bolt is drawn up snugly by means of its nut 18, the said links 16 and 17 will not bear against the edges of said leaves. The other ends of links 16 and 17 are apertured to engage/f apivot bolt 19 which extends through an eye 20-formcd upon a clip or small plate 21 which is secured to the outer leaf of the spring. Said clip 21 is usually fastenedto the said outer leaf by riveting as at 22 01' in any other desired manner, so that it' cannot slip upon the spring leaf. The eye 20 of the said clip 21 is also usually made a i little wider than' the leaf of the spring to pevent the links A16 and 17 from engaging t em.
The links 16 and'17 preferably extend in a slightly inclined relation to the planes of the spring lea-ves as clearly shown in the drawin the arrangement bein such that when t e leaves carrying the c ips 21 coil -or bow, the gripping plate or shoe 11 will gripping device having a transverse portion 23 extendin across the spring leaf to which the ip 2% is attached, and provided with coile portions at the sides as at 24, from which the ends 25 of the said springs extend one upon the outer face of each of the links 16, and 17. Bent portions 26 are also provided upon the end portions 25 which are adapted to project into. and engage apertures 27 and 28 formed .in the links 16 and 17. The coiled portions 24 of each spring extend around nd have a bear'- ing upon the head. of the lliolt 19 and the nut 30 applied to the other end thereof. The transverse portion 23 ihears upon the outer surface of the spring leaf'which carries the device, and the ends of the spring 25A will thus tend to move the links 16 and 17 toward the tapered portion of the spring,
whenever the leaves thereof fare straightened out under the actionof a load, and thus carry the brake shoe to a position where it will be ready to grip the spring leaves upon their rebound.
' In applying the grip mechanism to an l elliptic or a partially ellipticfspring, or to a spring of any other desired curvature, the
grips are usually secured to the leaves of the spring near the ends thereof, where the vsliding movement between adjacent leaves is greatest, 'so as-'to have the greatest movement retarding or brakin action upon the rebound of the spring.
he resiliency of lnot inter ered with in an the sprin as it straightens under a load, is
way
for as esprin Vthe shoe 11 is correspondingly advanc under the action of the spring ends 25, relieving the gripping action of the parte, but the recoil is Vretarded and modied to prevent excessive rebound, as the movement of the parts in a return direction causes the gripping action again. The device is especially useful when applied to vehicle springs, and 4'particularl to the springs of' automobiles ormotor rven vehicles.
While the sprin recoil grip may be applied to the ends o successivesprin leaves, as shown in Fig. 1, it will be un erstood v that a less nur'nber of grips may be applied the end portions of the spring leages `i ay be employed within the spirit and scope of the invent-ion.v Thus as shown in Fig. Grof the drawing the end of the spring leaf may be curled to form an attachin eye'29 for receiving the bolt 19 and holding the. grip device in proper position to secure the desired action therein.
It will be evident alsothat other minor details of construction may be altered if desired within the scope of the present invention. The arrangements should, however be such that as the leaves of thespring straighten under the wei ht of a load, the bolts '19 with the ends o the links carried thereby will be moved outwardly .along the spring, the arms 25, movingthe said links also in correspondence therewith so as to cause-the shoes 11 to take up any slack in the parts and thus always be ready to crowd the spring leaves tightly together upon the friction shoe 11 will be moved 'to grip the leaves when the spring is yielding under compression, all within theI spirit-and scope of this invention.
What is claimed is:
1. A recoil grip device, for springs hav- E ing arplurality of leaves, ada drawn ti htly about said leaves y the 1ongitudina movement of the leaves with re-v spect to each other for crowding them together upon movement.
. 2.
