. UNITED STATES PATENT OFFICE.
ALBERT E. LEACH, OF DETROIT, llIICI-IIGAN, ASSIGNOR TO THE STUDEBAKER CORPORA- .TION, OF SOUTH BEND, INDIANA, AND DETROIT, MICHIGAN, A CORPORATION OF NEW JERSEY.
LOCK-BARREL-LOCKING MEANS Application filed June 22, 1923. Serial No. 647,170.
To all whom it may concern:
Be it known that I, ALBERT E. LEAOH, a citizen of the United States of America, and resident of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Lock-Bar'i'el-Locking Means, of which the following is a specification.
This invention relates to means for looking lock barrels in position and has for its object the providing of such a means wheref by the lock barrel may be inserted into its support at any convenient time, and which after being inserted cannot be removed without the expenditure of considerable time, and material damage to the'parts involved.
Usually lock barrels are held in place by screws which necessarily must be exposed in some particular position and which are therefore readily removable from that position. This is a particular disadvantage in the case of automobile locks'where the time element needed to force a lock has an important bearing on theft insurance rates.
I provide a means for locking the lock barrel in position whereby there is no way to remove the barrel after it is locked in place except by materially damaging the barrel or support, and such removal must necessarily take a relatively long perlod of time. I
Another advantage of this locking means is that the lock barrel may be easlly and quickly inserted in its support at any time, the state of assembly of the support making no difference whatever to the time for in serting the lock barrel therein. This is again particularly advantageous in the building of automobiles where it is clearable to insert the lock barrel as the last operation of assembly so as not to interfere in the assembly of the rest of the parts.
The method I use is to provide a spring pressed plunger in the lock barrel which may be depressed flush with or below the surface of the lock barrel. I also providethe support with an opening of substantially the same size as the plunger and which may be matched with the plunger opening in the lock barrel. In assembling the lock barrel to its support the plunger is depressed below the surface of the lock barrel and the latter is inserted in its support and moved around until the plunger opening matches with the opening in the support which. al-. lows the plunger to move into the support.
The opening in the supportis blind and of less depth than the length of the-plunger so that the plunger remains partly in both'the lock barrel and the support, locking the same securely together.
In order to more fully explain my in-ven-' tion will refer to the accompanying draw} 'IIIgS 111 which a suitable embodiment of my invention is shown.
Flg. 1 1s a partially broken perspective view showing the lock barrel mounted in its support and showing the manner in which at is secured therein.
Fig. 2 is a view 'of the spring that tends to force the locking cup or plunger outwardly from the lock barrel. I
Fig. 3 is a sectional side view of the looking cup or plunger used to lock the lock barrel in its support.
1 is a support for a lock support lin this particular case is the transmission cover of an automobile. port 1 is drilled out to form an opening of slightly larger diameter than the lock barrel 2 and of sucha depth that when the lock barrel 2 is seated on the bottom of the opening its upper face is flush with the adjacent face of the support 1. The lock barrel 2 has a rod 3 terminating in a flattened portion 4: fastened to its revolvable part. When The supbarrel 2. The
the key is inserted in the lock and turned,
the flattened portion 4 turns and spreads balls or pins, as the case may be, into notches into the other side where it forms a blind hole 8 'of less depth than the length of the cup 6, preferable about half, and in such a position that when the lock barrel 2 is properly inserted in its support 1 the opening .5 and blind hole 8 are axially aligned. In
the operation of inserting the lock barrel 2 i in the support. 1, the spring 9 is inserted in the cup 6 and the cup 6 is then inserted in the opening 5 open end first. The cup 5is then depressed against the pressure of the spring 9 below thesurface of the lock-bart I the cup 6; ispositioried.
