ROBE-LOCK.

Specification of Lettersiatent. Application filed May 14, 1912. Serial No. 697,150.

Patented Sept. 9,1913.

To all whom, it may concern:-

Be it known that I, THOMAS P. Bacon, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have inventednew and useful Improvements in Robe-Locks, of which the following is a specification.

This invention relates to a lock, and par- I I ticularly pertains to a pad-lock for locking lap-robes and the like to supporting rails.

It is the object of this invention to provide a lock which is especially adapted for use in looking lap-robes and similar articles to suitable supports so as to prevent their being-stolen, and to produce a look so constructed that it can be securely clamped to articles of various thicknesses and locked thereon.

:The purpose of this invention is toprovide a pad-lock having a reciprocable bolt so arranged that it may be manually advanced in the lock casing toward a fixedkeeper carried by the casing and to rovide key controlled means for ocking t e bolt against retraction in. various positions.

The invention resides primarily in a substantially' U-shaped rigld clasp provided with a lock having a sliding bolt operating across the opening of theclasp and operat- 1s aperspective view.

either direction within the loc ing jaw fashion with the end of the clasp opposite the lock, and means for locking the bolt against retraction in various positions.v

The invention further consists of the parts and the construction and combination of Qparts as hereinafter more fullydescribed claimed, having reference to the accomdrawings, 1n which, I

Figure 1 is a side view of the invention with arts broken away showing it as applied 1n locking'a lap-robe to a rail. Fig. 2

P y ng In the drawings A represents-the lock casing which maybe of any suitable construction and which is here' shown .as formed with a pair of face plates spaced apart and joined together at their'ed es. Slidably mounted between' the two ace plates of the lock casing is a reciprocable.

olt 2, here. shown as rectangular in crosssection, on the upper face of which is formed a series of ratchet teeth 3. The bolt '2 is designed to extend some distance beyond the. edges of the lock casing A and is fitted with a handhold 4 on one end, by

which it may be moved longitudinall in caslng so as to dispose its inner end in any desired position in relation to a keeper 5 formed on clasp 6, on which the, keeper 5 is mounted,'.

is arched so as to form a hook which is debersto be locked together, .as will later be described.

The bolt 2 is designed to be engaged with the keeper 5 and locked against retraction so as to inclose the members it is desired to lock together within the space formed within the 'clas 6 and the bolt 2. The article to be fastene by the lock may, however, be clamped between the inner end of the bolt 2 and the keeper 5, where the occasion requires; the bolt 2 being locked against re- .traction in any desired position by means of a spring pressed locking pawl 9 mounted within the lock casing A, and positioned to normally engage "the ratchet teeth 3 on the bolt 2, as shown in Fig. 1. The pawl 9 is here shown as being in the form of a lever, plvotally mounted on a pin 10 carried by the side plates of the lock casing A, the lower end of which lever is held in normal engagement with the ratchet teeth 3 by means of a plate-spring 11 mounted on the end of the lock casing A, bearing against the underside of the upper end of the pawl 9 which extends upwardly at an incline.

. The pawl 9 is designed to be thrown out of engagement with the ratchet teeth 3 to permit of-a free reciprocation of the bolt 2 by means of a key 12 of any suitable description, the bit of which is inserted through a keyhole 13' formed in the lock casing A, and is arranged to engage or bear 'agsinst the upper portion ofthe pawl 9 signed to be placed over or around the memthe key 12 may be inserted and withdrawn from the lock casing irrespective of the position of the bolt 2; the pawl 9 acting on its release to immediately engage the ratchet teeth 3.

From the foregoing it will be seen thatv latter is thrown over arail 15 in the usual manner, as shown in Fig. 1. The bolt 2 bein retractedadxnits of the U-shaped clasp 6 geing positioned over the rail 15 so as to dispose the keeper 5 on the one side oft-he robe and the inner end of the bolt on the o posite side thereof. The bolt 2 is now a vanced so as to clamp the two folds of the lap-robe 14 between the end of the bolt 2,.and the keeper 5 ;,the spring pressed pawl 9 locking the bolt 2 against retraction. This being done the lap-robe 14 is securely looked upon the bar 15 against removal.

iloiaase ber a lock casing attache to one end ofsaid U-shaped member, tumblers carried by said lock casing, a holdingjaw formed upon the other end of said ut-shaped member, a bolt passing entirely through said lock casing, a holding face formed upon the end of said bolt, said face being adapted to cooperate ace with said holding 'jaw, a hand hold formed upon the other end .of said bolt, and ratchet teeth upon said bolt.

In testimony whereof I have hereunto setmy hand in the presence of two subscribing witnesses.
