This invention relates generally to slide bolt type'locks and more particularly to'a slide bolt type locking means which is suitable for use under 'adverseweather conditions to which it may be exposed. Y

Locks attached on fences oridisposed in outdoor "locations' are prone to rust and clog with dust. In many instances as a resultof this'the moving parts will-freeze'up rendering the lockitself inoperative andre'quiring" replacement at expense to the owner.

In order to weather-proof locks'various methodshave been tried such as morticingin the door to which the lock is attached or providing special housings or overhangs for the lock but these have proven unsatisfactory.

viding an integral handle lock and'boltel'ement slidably mounted on a track or guide intur n afiixed to afiist member whichis movable relative a second member having a keeper therein to receive 'said bolt element for locking the members wherein suitable gaskets flare disposed-between the boltel'eineng-the' guide and the locking tumblers :thereon and a rain drip guide is provided whereby the sliding handler.- ock andnbolt'ele-men'ts are rendered weatherproof.

The keeper element 2 "is also shown having a boss 10' and as shown iri'Figure 3 this boss includes a bore at 11 adapted torece'ive the'engaging portion of the j 'element' 9 when it is in locked position as shownin Figure 3 and more fully described hereinafter.

r Le t g m d; a .f;I;n order to hold :the barrel-type element 9 in"locke d position the stationary guideurod is provided "vtlith an' annular groove 17 at the predetermined locking position which grove will be engaged 'by a locking's'te'm 18. The locking stem extends through a bore 19 'in the handle 7 portion orileg Hand is normally held in disengaged posie tion by a spring member 20. It is prevented from esca ing Referring to the drawings, Figiires l and an attaching plate generally designated lgan d an independent A Keeper elementjZjaffixedto the membersgenerally designated A and B by any suitable means as rivets or the like to fixedly connect the attaching means so th at they v;- a jj The i d l z4visraiconvenfional type and? eannot beeasily removed fron'r 'the members ia an'd B. The members A and B are movable relative each other and are held in locked position by the structure forming the present invention.

The attaching plate 1 is shown as a single U-shaped fromthehandle element 14 by means of the threaded element 21 which aets ia's'wa' stop but allows the locking stem to extend therethrough into the cylinder lock" chain ber ,2 2 formed inthe handle at a point remote frornthe" stationary guide rod 6 Aslshown inFigure 3 the cylinder lock chamber 22 has a {threaded portion 23 which threadably receives the cylinder lock 24' so that in assembled position the cylinder lockface 25' is disposed just inwardly of the end of the ment with the annular groove 17- if the bolt 15 has been Sealing means 'In order to keep the simple relationship between the stationary guide bar 6 and the barrel type bolt mechanism free of dust and rust, a seal is provided as at 30 which is mounted on the barrel portion of the bolt mechanism and is free to move therewith to maintain the surface of the stationary guide bar clean and to prevent the entrance of moisture into the bore 12 of the leg 11 of the barrel bolt type mechanism and thus it provides a weatherproof lock which will not rust up during the ordinary use and operation of this type mechanism.

The seal 28 and the rain-drip protector 29 also act to prevent the entrance of moisture into the locking mechanism and through the various chambers and locking stem bores into this mechanism and thus they also act to maintain the weather-proof condition of this particular structure.

In phantomized form, as indicated in Figure 3, it is obvious that additional grooves can be cut in the stationary guide bar 6 so that the barrel-type element 9 could be held in the open position as well as the closed position if it is desired. In the open position the locking stem 18 would engage this groove 31.

It will be understood that the invention is not to be limited to the specific construction or arrangement of parts shown but that they may be widely modified within the invention defined by the claims.
