Application January 2, 1942, Serial No. 425,441

4 Claims. (01. Ya-35) I This invention relates to padlocks, and more particularly to a novel padlock of a water resistant or rain-proof type.

An object of the invention is to provide a device of the type which has a structure designed to draw ofi drops of rain or other moisture from points of entry into the padlock casing.

Another object of the invention is to provide a padlock hasp or shackle having dependent protuberances adjacent the points of connection thereof with the padlock casing.

Another object of the invention is to provide a padlock key having novel multiple conformance requirements for operation in a key-seat designed to admit the same.

Other and further objects of the invention will be apparent as the description proceeds, reference being had to the accompanying drawings, in which:

Fig. 1 is a side view partly in elevation and partly in section of a padlock embodying my invention.

Fig. 2 is a vertical sectional view on line 2-2 of Fi 1.

Fig. 3 is a view in horizontal section on line 33 of Fig. 1.

Fig. 4 is ahorizontal sectional view on line 4-4 of Fig. 2.

Fig. 5 is a detail perspective exploded view of the retractive tumblers and. spring mechanism.

Fig. 6 is an inverted View partly in elevation and partly in section on line 66 of Fig. 1.

Fig. 7 is a side View partly in elevation and partly in section of a modified form of the invention.

Fig. 8 is a view taken on line 8-8 of Fig. 7.

Fig. 9 is a view taken on line 99 of Fig. '7.

Fig. 10 is a bottom view in elevation of the padlock showing the key chamber closure.

Fig. 11 is a side view in elevation of the device.

Fig. 12 is a view partly in section and partly in elevation of another modification of the device.

Fig. 13 is a view taken on line 13-43 of Fig. 12.

Fig. 14 is a bottom view in elevation of the padlock.

Referring more particularly to the drawings, the numeral Hi refers to the device in general, having a casing H comprising an integral top I2 and the wall portion l3. A bottom or end wall 14 is edgedly and outwardly flanged at i5 to receive the rolled lower edge IQ of the casing wall l3. Integral with said end wall i4 is an inwardly turned cylindrical sleeve ll, having a longitudinal slot at l8, for a portion of its length,

and an aperture at l9 disposed substantially oppositely in said sleeve at the inner end thereof.

A barrel, 2!] is rotatably held in sleeve IT, by means of the ring 2!, in turn held in a circular groove at 22 of sleeve ll.

Integral with the barrel 2!] is the extension 23 and eccentric cam 24 topped by the axial pin 25 journaled in the cavity 26 centrally and interiorly of the top I 2.

A key, 31), has a slot at 3|, for a portion of its length from the insertable end thereof, adjacent an edge thereof and parallel thereto.

The barrel or cylinder 20 carries a spring 32 fastened at 34 of the key-seat, and having an outwardly disposed end 35 adapted to normally project through aperture 36 in barrel 20 and into a registering aperture [9 in the sleeve II, to lock the said barrel against rotation.

The barrel 2:: also contains an irregularly/undulating bar spring 3'! fixed to lie along an edge of the key seat. An edge 38 of the key 30 is cut -to conform with the bends in the spring 31.

The key 30 is edgedly and oppositely slotted at 39 and, 39' in unequal degree to permit turning thereof within the complementary unequal arcs 40 and 41 of the ring 2i.

The key 30 has a row of aligned apertures 42, a cog wheel 83 adapted to mesh therein is journaled in the key seat, and the said key has a beveled point 44 adapted to withdraw the retractive tumblers 45 and 46 against the coil springs 41, all of which has been previously disclosed in my application filed Sept. 15, 1941, and bearing the Serial Number 410,824.

When the lock is closed, the cam 24 abuts against and securely holds the long arm 50, which is integral with the shackle 5|, thus also retaining securely the short arm 52 within the aperture 53 of the casing wall IS. A detent pin 54 in the arm prevents the withdrawal thereof through the aperture 55 in casing IL.

A salient feature of the invention resides in the pendent lobes or protuberances 56 and 5'! disposed at each end of the shackle. Drops of water, as from rain will tend to draw toward the said pendent lobes and drop off at these points.

Fig. 7 shows a modified form, in which the numeral Hiil represents the device generally, having a casing wall lili and an integral top I02. The wall Hill has its lower edge Hi3 rolled about the bottom wall IE4, the latter having an integral, central and inwardly directed sleeve I05 having the flange 186 at its inner end.

In this form of the invention, the shackle I01 when pressed downwardly, after use of the key I08, is released to swing about a vertical axis in opening for engagement with an object or obj- J'ects to be locked.

The shackle IN is attached at one end by means of the connecting element I08 to the swivel post I09, and at the other end to the integral, inwardly and upwardly disposed keeper element H0. The swivel post I09 is bored from the upper end thereof to accommodate the coiled expansion spring I. The cylindrical wall II2 of the bored portion of postIDS is-apertured horizontally at II3 thereof to act as a keeper. The offset latch II4 normally is extended into keeper H3. The said latch has a body member -II5 which is longitudinally slotted at I I6 and held for limited sliding movement on the pins Ill and II 8. The coiled springl I.9.tends to return the latch to locking position. The barrel or cylinder I20 is similar to that in the preferred form of theinvention as to. internal mechanism, but

has an extension I.2I, .journaled in the casingtop ['02, which has a hair spring anchored there- "throughatone end and has the other end thereof "engaging'a pin I22, 'also serving'to return the barrel and latches to the lockingposition. .The

'latch I'23' engages. in keeper. I I0, and. is similarly mounted for limited sliding movement on the pins I24 and I25, and also has the coiled spring for urging the latch into the keeper. The barrel I20 has atits outer end, a slide adapted to cover "the outer end of the;key-seat. The slide I26 is .moved over the key-seat .by the circular .coil

spring I2I.disposed within the ring I28.

Another modified form of the invention is "shownin'Figql2'of the drawings. A casing '20I .cam 2 which turns against the vertical spring 2I2, thelatter' being interposed to prevent wear .between a rubber. cup 2I3 and said cam. The rubber cup 2-I3 serves to keep water fromthe internatmechanism .of the padlock, as does .a

smaller rubber cup 2I4 adapted to receive the opposite and short arm 2II of the shackle 2I5. The long arm 2I6 has the detent pin M8 to prevent removal of the shackle from the casing ZOI through the aperture 2I9. The rubber cups 2I3 and 2I4 are cemented or vulcanized to the casing 20I to prevent entry of moisture.

It will be understood that the device is capable of various modifications in structure and design, Without departing from the-spirit of the invention, within the scope of the appended claims.

Having thus described the invention, what I claim and desire to secure by Letters Patent of the United States, is:

1. In a padlock, a shackle, a cam rotatable on .:a .vertical axis within said padlock, a short arm on said shackle extending horizontally inwardly thereof, the said padlock having an aperture :adapted to seat said short arm, a long arm on the opposite end ofthe shackle extending horizontally inwardly .thereof .and bearing against said cam, whereby whenthe.camisextended against the long arm the Shortarm will be locked securely in said aperture.

2. In a padlock,.a casing,-a shackle, having integral arms extending within the casing, and rubber shield means attached to .said casing and .freelyiembracingsaidarms wherebymoisture will sides of said casing, one of said means being-releasable from said casing by bodily displacement of said shackle transversely of said casing-and lock controlled means for preventing. such bodily displacement of said shackle.

ANTON ROBER.
