(c1. 70-125 i I (Granted under Title 35,113. Code (19s2' ,fseci6) The inyention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without payment of any royaltiesthereon'or therefor. I
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. Q L s w Accordingly, it is an object of the present invention to provide a weather-proof islide bolt'tyipe lock relatively simple in design having a minimum number-of'parts which lock is easy to install vand operateand is adaptcdvt'oi take 'a standard type locking turnbler therein. 1 i It is another object of the present invention topfoVide a weather-proof slide bolt "type lock in. which the handle is .so disposedv that it can swivel through 'an arc'in excess of l80.,x 1 .L s Further objects and advantageshofthe invention will United? States PatetitO 2,912,845 I 7 Patented Nov 17, 1959 V bore 5 which bore 8 s l idablyreceives an integral handle The present-invention overcomes sthis-problem by proand barrel type element generally designated 9 slidably mounted on the stationary guide rod 6, as is clearly shown in Figure 3 of the drawings, It .will be understood that while the attaching plateis shown as an integral u-shaped unit with boss elements 3 and 4 that the bosses can be constructed and attached independently'of each other provided they 'arernaintained in proper spatial relationshipso thatinassembled 'position they will hold the stati'onary guide rod and bar'rel-bolt type element in proper operative relation.
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.
Integral hgmdle and barrel-typelelement The"integr 'al"handle and'bar'rel-typ'e element 9 comprisesa substantially L-shaped'member. One leg12 has a'bor'e 13 which extends substantially the full length of this leg to slidabl'y mount element 9' on the stationary guide rod 6 whereby the other leg'14 forming an operating handle at right'angle's thereto will extend betweenthe b'osses 3 and 4 of theattaching plate 1; Since the at taehin'g plate is open onjo'ne side, handle 14 is free to rotate through an are extending fmore than 180 as is shown in Figure 2 of the drawings. If,ho-weyer, the bosses 3 and 4 werernerely held in 'spatial relation by their attached position tothe'mernbe'r A',- the handle could rotate a'fu113'60s r t I t Figure-'3 further shows th't the barrel type element 9 has a" portion of lesser diameter forming a bolt'as at which is in sliding ;fit arrangement with the bore 11 on the boss 10 of-the keeperelernent- 2. 'Thereduceddiaim eter of 'the -bolt IS-forms a shoulder "as at 16 sotha't when the bolt isin locked position the shoulder 'wiljl'abut the boss-4;" The bolt will be constructed of sufiicient length so that in abutted position it will extend into the bore 11 onthe keeper 2' to provide the desired locking engagement between-themembers A and B an of which become evident from the following description with the rain-drip protection means on isr'clearly shown" in Figure 3 of the drawings;
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.
