To all whom i may concern:

`Be it known that l, dci-1N Fi'. livrons, ci Wilkes-l3arre, Luzerne county, and. State oi:b lennsylvania, have invented certain new and useful Improvements in Locking Delvices; and Il hereby declare that the followautomobiles, and yachts, but also applicable for the purpose ot quickly and securely locking' any relatively movable part-s, as will be appreciated by those familiar with the art when the invention is once understood.

The object of the invention is to provide a lock having' a bolt or plunger pin which may be easily and directly projected by hand so as to lock the parts, and when projected will be itself automatically locked in position so that it cannot be retracted or released until a key-operated controlling device is manipulated. The said controlling device may itself be a permutation or combination loclr (preferably I employ a modilied Yale lock) which Will require a special key to operate it; so that when parts are locked by my invention it Will be practically impossible to unlock or release same Without a special key which cannot be readily duplicated.

Preferably l so construct my devicel that when the lrey-controlling device permits retraction of the locking' bolt, the latter `Will be retracted instantlyV by a spring; I do not care to confine myself to a spring,n retracted locking bolt however as in some instances it both manually projected and manually retracted.

ln order to impart a clear understanding of my invention l Will new explain the same as embodied in an cllicient torni of locln especially adapted for locking the steering gear or shalt of automobiles, motor boats, and the Mira-which will enable any one `skilled in the art to fully comprehend the invention and lits adaptability for other uses in the arts; it being understood that the linvention not restricted to the Aparticular form and proportions oit' parts nor to the particular application indlcated in tbe drawings and described. indetail in thefap pended specifications; l have summarized in the claims the essential features of the ine v'entlon, and the novel parts and combination of parts oi the lock illustrated in the drawings which l consider Within the scope my invention, for which l desire protecion. I

ln said drawings-Figure 1 is a side ele-- vation of the complete locking device apm a plied to part ol.E the steering shalt of an autou mobile lor instance, the locking,r bolt being' shown retracted. Fig. 2 is a iront elevationl ot Fig. '1. Fig. 8 isa vertical central section through Fig. 1 or on the line 3 3, Fig. 2. Fig. .4 is a vertical section on line 4 4, Fig. 3. Fig. 5 is a view similar to Fig.. 3 showing the bolt projected or in locking position. Fig. 6 is a vertical transverse seew tion on line 6 6, Fig'. 5. Fig. l" is a horiif' Zonta] sectionk on line 7-7, Fig. 5. Fig. 8 is a detail View of the loclrinpr linger de tached. Fig.- 9 is a detail view of the bolt l detached. 3

As shown in the drawings it represented@ n purpose for which the lock is shown as ein ployed in the drawings. The form ofthe casinginay be varied to suit the purpose :tor which the lock is to be used. u

ln the front part of the casing is a locking bolt l, Which is preferably mounted to `slide longitudinally, in the casing C, and may be supported and guided lit its front end in the front Wall oi the casina', and at its inner end in an opening' E in a plate 2 removably secured in the casing by a screw Elfi For convenience et construction l preferably attach 'a hollow cap l to the outer end of the bolt by means of a threaded socket' engaging; l a threaded shank lh on the end oit the bolt as shown. 'lhe part l*L may be oli' brass or bronze, but l prefer to make the part l. el:n hardened steel. it Will beV` seen thatftlie bolt l isinovable at right angles to the slee'e 1 titl titi

'l and shaft The bolt is normally retract- .ed so as not to interfere with the sleeve or shaft by means of a suitably arranged spring 3 which is preferably placed around the bolt within a recess in the cap' la, andbetween the head of said cap and the plate 2. The spring 3 is a helical expansion spring and normally tends to retract the bolt to the position indicated in vFigs. l and The bolt or plunger Vpin can be projected into locking position by pushing it inward, oreferably manually,` against the resistance of spring 3 thereby putting` it under compression as indicated in Fig. 5. In order to hold the bolt in its-projected position 1 form in its under side longitudinal grooves il@ which are separated by an intervening wall 1f; and the grooves 1e unite at their outer ends with a transverse groove lh in the bolt. Into the grooves in the underside of the bolt there are adapted to project locking fingers or dogs 4, which in the construction shown are preferably formed integral out of a strip of sheet steel bent upon itself as indicated in Fig. 8 so that the extremities of the locking fingers 4 tendto press toward eachother but me normally held apart by the wall 1f between the grooves le, when the bolt is in retracted position. The locking fingers 4 may be confined in the casing by means-of a pin 4d engaging the bend of the metal strip and tapped into the casing, as shown, belowl the bolt l; the upper ends of the locking fingers 4 are preferably deflected as shown at 4a so that said ends will lie partially within a slot 5a in a plate 5 which is fastened within the easing by means of screws 2b, 5b, as shown, the upper end of plate 5 fitting' over plate A 2 and the opening or slot 5 in the plate being elongated sufficiently to permit the passage of the bolt l therethrough as shown. The slot 5a is of such width as will permit the locking fingers 4 v'to be sprung apart sufficiently to release the pressure upon the bolt rib lf and thereby allow. the spring 3 to retract the bolt into the position shown in Fig. 3. The slot 5a however prevents too great separation of the fingers`4 and will keep them in proper position for rengagement with the wall lf. When the bolt is projected the transverse slot l in the bolt comes opposite the fingers 4 and the latter, i

if permitted, will close together within the slot lh and lie behind the inner cnd of the wall "1f, which forms the locking abutment of' the bolt, and when the bolt and fingers are in such position the bolt cannot be retracted because the fingers 4 lying behind theend of the wall 1f absolutely prevent retraction of the bolt. hen the bolt is retracted however as indicated in Fig. 8 the ends of the locking fingers 4 will press against the sides of the wall 1*. Preferably I notch the 'forward ends bf the wall 1f slightly as at 1g, so that when the bolt is retracted the pressure of the spring fingers 4 will tend to hold the bolt in retracted vposition in addition to the action of the spring 3, thus preventing any possibility of the casuall projection of the bolt by jarring of the lock casing, and also preventing rattling of the bolt; but the notches will not prevent the easyv projection of the bolt by inwardly directec end pressure of the finger thereon.

From the foregoing it will be seen that in its normal position the bolt or plunger pin is retracted by the spring 3 and yieldingly held in -such retracted position by said spring and locking fingers 4 engaging the notches lg in the sides of the wall lf; that the bolt can be readily projected into locking position by a push of the thumb or finger against the end of the bolt, or bolt cap la; that when the bolt is projected into locking position as indicated in Fig. 5 the locking fingers 4 spring together in slot lg behind the end of the abutment or wall lf and positively lock the bolt in projected position; and that the bolt l cannot then be retracted unless in some manner the locking fingers 4 be separated or withdrawn from theirbolt locking position. This separation of fingers 4 might be effect-ed in various ways but I prefer,-f0r the purpose of safety and to prevent unwar-v ranted tampering with or vretraction of the bolt,-to employ a lock-controlled actuating device to release the fingers 4. As indicated in the drawings- I preferably employ the ro-V tary shaft of a cylinder, combination, or permutation lock and for this purpose I secure within the casing C, parallel with and' below the bolt l and exterior to the locking fingers 4, a small cylinder lock 7 which may be of any approved construction; and which ordinarily comprises a rotary key-shaft 7l and an internal set of tumblers that lock this keyshaft against rotation unless the tumblers are released by a specially designed key. This kind of permutation or combinar tion lock is well known and I do not consider it necessary in the drawings to show any details' of construction thereof, it being understood that such locks are of different construction and made to require individual keys. My present invention has nothing to do with the internal construction of such lock or any kind of cylinder lock, whichl may wish to employ in its place. However in adapting such a lock to my invention I provide its key-shaft 7n with an extension 7h on its inner end, which extension may be flattened on opposite sides as indicated in the drawings and projects between the opposite locking fingers 4 when the parts are in assembled posit-ion, When the key-shaft 7 is turned so that its actuating key can be withdrawn,'the end 7b (which practically forms a double cam) therrstands with its shortest diameter between the locking fingers 4, and will allow the upper ends of said locking fingels 4L W lock said bolt as ndicnlt.
