application. filed October a7, 1326. 1 s r a no, 1 44,5 43.

This invention relates in general to, irn-i provements lIl' padlocks and more pttltlcll-l V rubbe l5 fi ted; .lII t -uppe g of h Pat larly in the type generally employed for-the purpose of locking spare 5 automotive vehicles. 1 e

The object of his, invention is the provision of a shackle ofn'ovel form to engage the lugs, used to secure a rim, in such-a manner l the lugs and prevent movement of the removable member or the unauthorized insertion of a tool for separating the shackle from the casing without unlocking the padlock. I Another object is the provision of a cushinning member in the upper edge of the padlock casing adapted to coact with the improved shackle for the purpose of further I eliminating relative.movement of the locking assembly and the consequent rattling.

A further object is the novel locking bolt to engage the closely spaced notches of the improved shackle, whereby a finer adjustment-avill be possible in order to force the locking the shackle and cushioning member as a rattling preventative. 4

VTith the foregoing and other objects in view the invention consists in the combination of parts and in the details of construction hereinafter set forth, certain'embodimerits being illustrated in the: accompanying drawings, in which- Figure 1 is a view in front elevation of the padlock casing and shackle in assembled position; I

Figure 2 is a vertical section'through the casing showing the manner of attachment of the cushioning device to the casing;

Figure 3 is a vertical section through a portion of the spare tire rack and securing brackets, showing the padlock attached thereto.

Figure l is a view in front elevation partly in section, ofthe padlock with part of one face of the casing removed. 7

Figure 5 is a detail perspective of one of the locking bolts of the padlock.

Referring more particularly to the drawof which pass through the casing 1. The leg 2 is straight while the leg 3'is bent outwardly at 3* at its upper extremity from parallelism at an obtuse angle. The leg 3 is bent back into parallelism with the leg 2 at a point 3". i

Wheel on i -"es i reduced portiont an'dgan enlargedfianged tire on the spare wheel as to conform withv provision of a bracket against 7 10 is loosely ings, the shackle has two legs 2 and 8 both the usual manner As'shown in Figure 2 a. cushioning-man here of suitable flexiblematerial, such as" lock casing: The member's consistser a- This t in the casing! cushioning member isso fittedthat'it'may g be replaced by merely separating the two halves of the ordinary casing and slipping the reduced portion 4 in the aperture of the casing.

As shown in Figure 4 the locking mechanism comprises a pair of opposed locking bolts 11, with enlargedend ortions 11 having a plurality of teeth 12 a apted to engage the closed spaced notches 2 and 3 of the shackle legs 2 and '3. r The bolts 11 have apertures 13 which are engaged by a key to slide the bolts one upon the other against the actions of the springs 1 into an unlocked position. Upon removal of the key the springs 14 force the bolts into a position where they are adapted to engage the shackle in locked engagement. The main feature in this connection as applied to the present invention is the provision of the closely spaced notches on the shackle legs, and the plurality on its other slde, the possibility of rattling is effectively eliminated. i

In Figure 3 is shown a particular adaptation of the improved padlock assembly. The spare tire securing means shown consists of a skeleton rim or )late 9 and ademountable'rim 10 within which a pneumatic tire or spare casing is mounted. The rim fitted-over the plate 9 and an angle iron lug or bracket 5, bolted at 11 to the plate 9, is provided upperlextremity'of its upright portion and an opposing removable lug 6, having at its 10c with an orifice near the lower end a wedge-like portion 6, is nor-" mally held with the portion 6' lying between the plate 9 and the rimlO, tending to spread them apart, and secured to the tire rack in by a fastening bolt 7 with its corresponding nut 8.

The brackets 5 and 6 are provided with aligned apertures through which the straight leg 2 'of the shackle is passed. The two brackets 5 and 6 are also provided with openended slots at their upper extremities to receive the bent leg 3 of the shackle which rests in snug engagement. Obviously to lock the bracket assembly the casing 1 is protruding shackle legs.

placed on the two Figure 3 shows the snug engagement of the particular type of otlset shackle described, together with the cushioning menu 1 her at pressed against the bracket 6. The bend in the shackle, While producing in this particular use, does not involve any great amount of expense or precision, which is due to the simplicity of its nature. This feature 15 combined With the inexpensive and simple replaceable cushioning excellent alitia'attling makes for elliciency as 111 a padlock, a casing, a substantially U shaped shackle the legs of which pass through said casing, said casin having a cushioning member mounted in the upper edge thereof between the joined legs of said shackle, said cushioning device consisting solely in a solid member of flexible material reduced at its mid'portion and removably fitted in said casing.

In testimony whereof I aliix my signature.

device, constitutes an locking device which well as economy.
