mounting for the cover and spring tension to hold thesame in either open or closed position.
And astill' further object of this invention is" to provide a dust cover for locks of the character m described; which is an'improvement' and a simplification over other structures heretofore proposed and which may be readily assembled with thelock;
With the above and other objects in view which :w-ill appear asthe description proceeds, my invention. resides: in the novel construction, combination. and arrangement of parts substantially as:
hereinafter described and more particularly defi'ned' by the appended claims, it being understood 25 that'su'ch changes in the precise embodiment of thei herein" disclosed invention may be made as comewitlfin thesco'peofthe claims.
'"I-nr the" accompanying: drawing, I have illus trated one completeexample of the physical em mtbodiment of my invention constructed according o thc blesti-modeIf'haveiso far devised for the practical application of the principles thereof, and in which:
Figure 1 is a side elevation of a lock with parts u broken away and in section and illustrating the dust cover of this invention applied thereto;
Figure 2 is a front view of the lock with parts of the cover and its mounting means broken away; and Figure 3 is a perspective view of the cover and its mounting means shown disassembled and separate from the lock.
Referring now more particularly to the accompanying drawing in which like numerals indicate w like parts throughout the several views, the numeral 5 designates the casing of a conventional tumbler lock. The casing is bored to receive a cylinder 6, which has the customary tumblers '7, only one of which is shown. As is customary, the amicylinder is secured against rotation in the casing by the engagement of the tumblers in a groove 8 in the casing, the tumblers being retractable out of the groove upon the insertion of a proper key into a keyway 9 to free the cylinder for annotation.
1933, Serial No. 74,993 9 Claims. (CI. 70-4 invention. relates to certain new and useful improvements in key operable tumbler locks The front end of the casingfi is provided with an annular flange 10", Ithe front edge of which is stepped or'reduced in diameter as at llto form a grooves At. one point in its periphery, the groove formedi by the stepped portion 11 is grad- 92"; ually increased in depth and width as at 12. to
1 terminate in an enlarged depression or pocket 13'.v
Into this depressionorpocket, 2; lug 14'formed on a cover 15 projects. i
iTheicover 15 is of substantially the same die 5w ameter' as the flange 10 and covers'the exposed. front end of the lock to protect the same from: the elements.
A spring ring 16, having straightend portions 17 adapted to be received in: a bore 18in the ing wa 1.4 'of the cover is provided to hingedly mount'the: cover and also exert spring tension for releasably holding the cover "in either closed or openposition, as willlbe hereinafter more fully de'-. scribed. v 75;
The major portion of the spring ring 16..lies' in a common plane and is'received in thegroove.
are disposed inwardly of thema'jor plane of'the ring. The position of the end portions l'lxwh'en' the ring, is free is such that when assembledrwith the'cover and the: casing; a spring tensioniwlil'lf be exerted onzthe covertending; to draw thecoiver 5;; towardsqthe: casing F v The assembled ring and cover are retained in position on the flange 10 f the front end of hinged lug 14, the cap has an opening 24.
The spring tension exerted on the cover by 9% the spring ring is utilized to releasably hold the cover in either closed or open position. To obtain this function of the spring ring, the cap 20 has projections at opposite sides of its opening 24, which project forwardly of the plane of 1 the front of the cap and also outwardly beyond its circumference to form a fulcrum about which the spring tension tends to swing the cover.
25, key-Way, a cover for ;therefor, single means cover, a yieldable hinge pin plane passing through the axis of the hinge connection and the center of curvature of the projection 25. In other words, the point of contact moves from one side to the other of dead center, thus enabling the spring tension exerted by the ring to hold the cover in either position.
The slight space between the cover-and the adjacent wall of the cap its closed position and which is brought about by reason of the projection of the fulcrum outwardly beyond the front of the cap is not objectionable.
A finger engaging notch 26 is cut into the cover diametrically opposite its hinged mounting to facilitate opening the same. p
From the foregoing description taken in connection with the accompanying drawing, it will be readily apparent to those skilled in the art, that this invention affords a simple but very effective mounting for dust covers of key actuated tumbler locks.
What I claim as my invention is:
1. In combination with a key operable tumbler lock having a lock cylinder provided with a the frontend of the lock, and a single element to hingedly mount the cover for movement to and from closed position about an axis spaced from and angular to the axis of the cylinder and to yieldably hold the cover in either closed or open position, said single element consisting of a wire loop encircling the end of the lock with a part connected with the cover.
2. In combination with a lock and a cover to hingedly mount the cover and exert a spring tension on the cover, said single means consisting of a wire loop encircling the end of the lock with a part connected with the cover, and common means to --provide a fulcrum about which the cover swings response to said spring tension to yieldably hold the cover in closed position and also retain the wire'loop assembled with the lock.
3. In combination. with a lock and a hinged cover therefor, a fulcrum engageable with the to mount the cover and cooperate with the fulcrum to yieldably hold the cover in closed or open position, and a cap to hold the yieldable hinge pin assembled with the lock, said fulcrum being part of the cap.
4. In combination with a lock and a cover for 20, when the cover is lock to hold the front end thereof, a wire ring disposed in an annular groove encircling part of the lock with a portion thereof engaged in a bore in a cover part to provide a hinged mounting for the cover.
5. In combination with a lock and a cover for the front end thereof, said cover having a bore in a part thereof, a wire loop encircling part of the lock and having its ends disposed in said bore to hingedly mount the cover, and a cap to hold the'wire loop on the lock, said cap carrying means engageable with the cover as a fulcrum about which the cover swings in opening and closing movement.
6. In combination with a lock and a cover therefor, a lug on the cover having a bore, a wire loop encircling part of the lock and having its ends received in said bore to hingedly mount the cover, and a shell engaged over part of the the wire loop in place.
7. In combination with a lock comprising a casing and a lock cylinder mounted therein and a cover for the front end of the cylinder, means to hingedly mount the cover comprising, a wire loop disposed in a groove in the casing and having its ends received in a bore in a'cover part, and a cap engaged over part of the casing to hold the wire loop in place. v
8. In combination with a lock comprising a casing and a lock cylinder therein, the front end of the cylinder, a wire loop encircling part of the casingand' having its ends disposed in a bore formed in a cover part, a cap engaged over the casingto hold the loop in place, and a projection on the cap and cooperating with the resiliency of the wire loop to yieldably hold a cover for ing a part thereof disposed in a bore in said lug,
said spring ring exerting a spring tension to draw the cover toward thecasing, a cap engaged over the spring ring and hold the ring in position, and means on said cap to form a fulcrum to cooperate with the spring tension of the. ring to yieldably retain the cover in either closed or open position.
