Application led .'unc 9, 1924. Serial No.'718,731.

`T all whom t may concern.'

Be it known that I, Foimnsr H. SPENCER, a citizen of the United States, residing at Spirit Lake, in Kootenai County and State of Idaho, have invented certain new and useful Improvements in Padlocks, of which the followingis a specification.

The present invention relates to improvements in padlocksof the type generally employed for the purpose of locking spare wheels to automotive vehicles, and especially those which carry disk wheels for this purpose. The primary object of the invention 1s the provisionof a tensioning device combined with the padlock for the purpose of preventing relative movement l between the padlock and the fastening lug of the rack which carries the spare wheel, when the wheel is locked in place. By the utilization of my invention the padlock is `restrained from movement with Y consequent rattling which would otherwise occur due to the vibrations of the traveling vehicle. A padlock so equipped -is applicable for use in many other ways, but for convenience of illustration and description I have herein y referred to a spare wheel as an exemplification of my invention. The purpose of my invention is accomplished by mounting a tensioning device `on the lock casing between it and the hasp for engagement of the free end of the tensioning device with the fastening lug of the wheel rack which in this instance supports a spare wheel. By

. means of the tensioning device the padlock is held in place against movement with relation to the` lug. The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully set forth `and claimed.

In the accompanying drawings I have illustrated two forms of the physical embodiment of my invention, one showing the device of the invention permanently attached to a padlock and the other illustrating the device as a removable attachment for use with standard forms of padlocks, and showing the best modes I have thus far devised for the practical application of the principles of my invention.

Figure 1 is a view showing a padlock attached to a perforated rack lug and held in horizontal position by the action of the tensioning device of my invention.

Figure 2 is an enlarged view of a padlock `showing the device of my invention in section. i

Figure 3 is a perspective view of the device used as a removable attachment on a padlock.

Figure t is an edge view of the padlockv f fastened In Figure l at 6 a perforated lug which may form part of the supporting rack fora sparewheel of'a vehicle, and the hasp is passed through this perforated lug for attaching the padlock thereto to prevent removal of the Wheel.

The invention contemplates a cup orreceptacle 7, which as shown in Figure 2 is formed by two halves cast or otherwise fash ioned integral with the two plates of the lock casing and projecting from the casing between the tangs of the hasp. Each half of the cup is fashioned with a fiange to provide an annular collar or flange around the end of the cup. Within the cup is lov cated a spring 9 bearing at one end against the lock casing and at its other end against an enclosing, slide cap lO. The cup and cap are cylindrical in shape, but of course may be made in other shapes, and they are held in relative position by means of an inner annular flange or collar 11 on the hollow cap. The flange 11 encircles the cylindrical cup and permits sliding movement of the cap on the cup, while the two collars or flanges prevent displacement of the cap. from the cup. The tendency of the /sprlng is to urge the cap away from the lock casing, but the cap may be forced to slide over the cup against tension of the lspring by pressure on the cap. Thus when the hasp is being passed through the perforated rack lug, the cap is pressed and held against the lock casing to permit free- 5 passing doin of movement of the hasp. Then when the hasp is locked in position within the lock casing, the spring 9 is .released and YJbyfits expansion :torces the cap against 'i the lug, inside of the bend of the hasp as in Figure l. The spring is ofsufficient strength to hold the cap again'stthe'lug' and pushy or force the look away from the lug in @such manner as to hold the bend of the hasp against the perforated-flug.;and thus maintain the lock and hasp in rigid position `with relation to the vlng vlnithisposition there Vis yno ginotion permittedbetweennjthe lock and its hasp and the lug, and therefore the hasp,cannot-,rattle `,inzffthe nlug. i'fhe normallposition ofthe cap, when not in-nse, is indicated in Figure 2 Where it ,isshQWn :L Xtendedi andbea-ring gainst. the yinner i-side of. thebend of the li-asp.

For .utilizing niyinvent-ion' in connection withv padlocks already -in Kuseggl provide removable attachmentas shown `in Figure 3.
