CYLINDER LQCK WITH STOP MEANS Daniel L. Biblin, Bristol, Conn., assignor to The Eagle Lock Company, Terryville, Conn., a corporation of Connecticut Application May 27, 1953, Serial No. 357,717

8 Claims. (Cl. 70-362) This invention relates to a cylinder lock with stop means and more particularly to a lock of the cylinder type which generally includes a cylinder that contains a barrel, or key plug, that is rotatably mounted therein.

An object of the present invention is to produce a lock of the cylinder type having stop means for limiting the rotation of the barrel in different positions relatively to the cylinder.

A further object of this invention is the provision of such stop means which may be located within the lock to selectively stop the rotation of the barrel relatively to the cylinder in any predetermined position.

f nited States Patent A still further object of this invention is the provision Y of such stop means which may be used without variations in construction to limit t-he rotation of the plug between any two of a predetermined number of positions.

Further objects and advantages of this invention will be more clearly understood from the following description and from the accompanying drawings in which:

Fig. 1 is a side view of a lock embodying the present invention.

Fig. 2 is a front view of the cylinder used in said lock.

Fig. 3 is a sectional side view of a portion of said cylinder on line 3-3 of Fig. 2.

Fig. 4 is a side view of said lock, partly in central vertical section.

Fig. 5 is a sectional end view on line 5 5 of Fig. 4, showing the stop means positioned for permitting right hand rotati-on of the barrel through a distance of ninety degrees.

Fig. 6 is a similar view showing the stop means positioned for permitting left hand rotation of the barrel through a distance of ninety degrees.

Fig. 7 is a similar view showing the stop means adapted for permitting right hand rotation of the barrel through a distance of one hundred and eighty degrees.

Fig. 8 is a similar view showing the stop means adapted to permit left hand rotation of the barrel through a distance of one hundred and eighty degrees.

Fig. 9 is a sectional end view on line 9 9 of Fig. 10 showing a modified form of my invention.

Fig. l is a sectional side view online 10-10 of Fig. 9.

Fig. l1 is a perspective view of a stop member used in the present invention.

In the embodiment illustrated in Figs. l to 8 of the drawings, my improved lock includes a cylinder having an axial bore 6, with opposed grooves 7-7 running longitudinally in the inner wall of the said bore and at opposite sides thereof. The said cylinder is provided at the front end thereof with an annular recess 8 which surrounds the bore and has an enlarged concentric portion 9 that is adapted to receive the head 10 of a barrel, or key plug, 11 which is rotatably contained within the said bore. The barrel has an annular shoulder 12, adjacent to the head 10, which is rotatable in the recess 8 and has a stop lug 13 that extends radially therefrom into the said recess 8.

In accordance with the present invention, there is provided, preferably in the bottom wall of the annular recess 8, a pair of holes 14-15 which are symmetrically located with respect to the vertical axis of the cylinder. A stop member 16 is provided within the recess 8 and is held in position by one of said holes for limiting the rotation of the barrel relatively to the cylinder between any selected two of a number of different positions; rthe said stop member 16 being preferably constructed of wire in the for-m Aof a ringv having a portion thereof cut away and an end portion bent perpendicularly to the plane of the ring to provide a finger 17 which extends into a selected one of the holes 14 and 15 to thereby secure the stop member i'n stationary position relatively to the cylinder for the purpose to be hereinafter described. v t

It will be understood that the barrel 11 is provided with a series of conventional tumblers 18 which are normally projected from the barrel into one .of the grooves 7-7 t-o thereby lock the barrel against rotation relatively to the cylinder; the said tumblers being key operated for retraction into the barrel to permit rotation of the barrel relatively to the cylinder.

The barrel 11 is preferably provided with an axially disposed square projection 19 to receive a locking bolt 20, having a square opening 19a therethrough, in different positions relatively to the barrel. The said bolt may be detachably secured on the projection 19 by suitable means, such as a retaining ring 21 which is secured to a cylindrical extension 21--a on the projection 19.

In the construction illustrated in Figs. l to 8, the stop member 16 may be secured to the cylinder in different positions so as to permit either left hand or right hand rotation of the barrel relatively to the cylinder, for a distance of ninety degrees, by simply inserting the finger 17 into either of the holes 14 or 15.

When the finger 17 is inserted into the hole 14, as shown in Fig. 5, the stop lug 13 may move between the ends of the stop member, andl right hand rotation of the barrel for a distance of ninety degrees is thereby permitted. When it is desired to permit left hand rotation of the barrel for a distance of ninety degrees, the said finger is inserted into the hole 15, as shown in Fig. 6.

When it is desired to permit right hand rotation ofthe barrel for a distance of one hundred and eighty degrees, the member 16 may be cut off, as shown in Fig. 7, and the finger 17 inserted in the hole 14. Left hand rotation of the barrel for a distance of one hundred and eighty degrees may then be obtained by simply turning the cylinder 5 upside down so that the stop member would be located at the top of said cylinder, -as shown in Fig. 8, instead of at the bottom.

It will be understood from the above description that the stop means of this invention may be located in a number of different positions by simply inserting the finger i7 of the stop member 16 into the proper hole for the desired results and without requiring any special tools or operation. Therefore, a specified lock having the required direction and distance of rotation for the barrel may be provided by simply assembling the parts of the lock to obtain the desired results and a substantial economy in the production of the lock is thereby attained. Also, different distances of rotation may be obtained for the barrel by merely either cutting ofi a portion of the stop member 16 or providing stop members, such as lr6-tz, having different spacings between their free end portions so that different distances of rotation may be provided for the barrel.

In the modified form shown in Figs. 9 and l0, the cylinder may be provided with a series of holes in different predetermined positions around the bottom of the recess 8-a and a pair of pins 23 and 24 may be inserted into any two of said holes to provide the desired degree and distance of rotation for the barrel.

It will be also understood from the above that the bolt projection 19 by'sirnplyplacing it upon the said projection in the required position'and then securing it in place by means of the retaining ring 21. Y
