Application filed Augustlli, 1922. "serial no, 581,969.' g

To all whom it may concern Be it known that I, Jon}; B. 'FREYSINGER, a citizen of the United States, and a resident of Stamford, in the county of Fairfield and; State of Connecticut, have invented certain new and useful Improvements in" Locks? 'vided witha circularopening'? in which avention, suchas will enable others skilled in the art to which it appertains to make and This invention relates to improvements in locks of the cylinder or pinftumbler type,

and more particularly to connections be-.

tween the key plug and the lock spindle or connecting bar, one object of the invention being to provide simple and efiicient means whereby suflicient lost motion between the key plug and the spindle or connecting bar I shall be effected to permit partial rotation of said spindle or connecting bar.

A further object is to provide simple means whereby acomplete rotation of the key plug shall cause less than a complete rotation of the spindle.

A further object is to so construct connections between a key plug and spindle that the same will operate to cause a partial rotation of the spindle during a full rotation of the key plug and at the same time prevent endwise displacement of the latter. I

With these and other obiects in view the invention consists in certain novel fea ures of construction and combinations of parts as hereinafter set forth and pointed outinthe claims.

In the accompanying drawings, Figure is a view in side elevation showing my im provements. Figure 2 is an end view. Figure 3 is a perspective view, partly in section. Figure 4 illustrates the shell or-extension for the key plug, and Figure 5 represents the spindle or connecting bar.

The cylinder of a pin tumbler lock is illustrated at 1, the same having a suitable escutcheon 2 at its outer end, and the plug 3 of the lock, which receives the key 4', extends through the cylinder,-said plug being made suflicient in length to project beyond the inner end of the cylinder as shown by dotted lines in Figure'l.

Upon the inner projectin end of the plug, a shell 5 is fitted'and rigid y-secured thereto by means of one or more ins, such as shown at 6. The shell'5 is so coated on and secured to the projecting portion of the plug, that it's'forward end may abut against the/1 inner end of the cylinder and thusiconstitute. means tofprevent outward displacementof the plug. a i l 315 The rear or inner end of the shell 5 is, pro,-

The'spi ndle I or connecting-bar. is provided at it's forward end, within the'shell 5-, withdi- .,ametrically opposite lateral win or-lugs 9,

9, forming, in eflect,-a cross-Bea within the. shell and preferably :at one'side-of, the Iongitudinal axis of the spindle; A-lug 10, Preferably out and b'BIItWfIOmthB metal of the shell 5, projectsinwa'rdly from the wall of the latter and is so disposed as to engage one or the other of the lugs or wings 9 of the spindle and turn the latter during the turn ing of the key plu It will be seen t at when the parts are in the positions shown in Figure 3 withthe lug 10 in the shell in engagement with one of the lugs or wings 9 of the spindle and the key plug is turned counter-clockwise, the lug 10 will travel away from the spindle lug until the plug shall have made one-halfof a rotation. The lug 10 will then engage the diametrically opposite spindle lug or wing 9 and, during the remainder of a com lete rotation of'the plug, the spindle will given a a one-half rotation to operate the bolt mechanism.

From the above, it is apparentthat the lost-motion between the key plu and the spindle is equal to one-half rotation of the construction of my invention without departing from the spirit of the, latter or limiting its scope. and hence I do not wish to restrict myself to the precise details herein set forth; I 1 1 u r v Changes might be made in the detailsof gig Havin fully described my invention whatl c' aim as new and desire to secure by Letters-Patent, is:

1. The combination with the casing and plug of a cylinder lock, of a hollow member secured to said plug and provided with asingle inwardly projecting lug, a Spindle entering said hollow member and having means within said member and in the path of movement of said inwardly projecting lug on said hollow member whereby a partial rotation of the spindle may be efiected during a complete rotation of the plug.

2. The combination with the casing and plug of a lock of a shell secured to said.

plug and engaging one end of the casing, a lug carried by. and projecting into said shell, a spindle entering said shell, and a lateral projection on said spindle within said shell in positiontobe engaged by the lug in said shell, whereby a complete rota-i tion .of-the plug will effect a partial rotation of the spindle. Y a

3. The combination with the casing and plug of a lock, of a shell secured to said lug and en aging one end of the casing, a lug carried y said shell and entering the wings projecting therefrom in opposite directions, and a lug carried by and projecting inwardly from the wall of said shell and adapted to engage one or the other wing o of the spindle, whereby a complete rotation of the plug will efiect a partial rotation of the spindle. p

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
