Application filed October 3, 1924. Serial No. 741,445.
" The main object of my invention is the prolvision of a lock whereby the main looking body is provided With ineans for looking the same in connection with the attaching nut 1 or releasing the same therefrom whereby the lock body 'may be readily rotated without in any way imparting movement to the locking nut, thus preventing unauthorizedpersons 'from Operating the lock and removing the lock from its locking position.
nother object of my invention is the provision of a lock of the above character which can be used eqnally as well on doors, such as garage doors and the like and is so construct-ed as to provide for suitable hand grips for'the person desiring'to operate the same whereby the lock may be readily detachcd or attached as desired.
VVith the above and oth'er objects in view, the invention consists in the novel features of constructionl the combination and arrangement of parts hereinafter more fully set forth, pointcd out in the claimsw and shown in the accompanying drawings, in which:
Fig. 1 is a top plan view of alock constructed in accordance with my invention.
Fig. 2 is a longitudinal section on the line 2-2 of Fig. 1,
Fig. 3' is a horizontal section on the line 3 -3 of Fig. 2, g
Fig. 4 is a transverse section on the line 4- 4 of Fig. 2 and,
Fig. 5 is a detail horizontal section illustrating a slightly modified form of the lock.
Refer'ring more particularly to the drawings, the numeral 1 indicates the body portion of my im roved lock whichmay be of any preferred orm and extending from each end thereof are the-hand grips 2 preferably tapered toward their outer ends as illnstrated in the drawings. The body member 1 has an annular collar 3 extending from one face thereof and extended into the body thru the collar 3 is a bore 4 which is provided with an inner reduced end 5.
Arranged within the bore is the looking drum 6 having an annular enlarged portion 7 which is provided at spaced interva s with cylindrical recesses 8. Surrounding the lock drum and threaded into the outer end of. the bore 4 is a retaining collar 9 the inner end of which abuts against the face of the portion 7 for retaining the drum within the bore 4. From this it Will be apparent that the collar 9 and the body portion 1 of the lock may be rotated about the drum While the drum remains stationary.
The looking drum 6 is provided With a central t-hreaded bore 10 adapted 'to receive the bolt 11 which may be carried by any-` object to which it is desired to apply the lock and When the drum G is threaded on to the bolt 11 the body portion 1 of the lock may rotate upon the drum Without moving the drum. 'A
In order to connect the body portion 1 of the lock'with the drum 6 for rotating the drum to move the same upon the bolt 11, a looking bolt 12 is provided which is slidably mounted within a. bore 13 formed in one of the hand grips 2. The outer end of the bore 13 is normally closed by means of a threaded plug 14. The looking bo1t'12 is provided With a transverse recess 15 and movable within this recess is a pin 1G carried by the rotatable lock member 17. This lock member 17 may be of any conventional type Wherein a portion thereof is rotatable and connected to this portion which lis rotatable, is the pin 16 Whereby when a key is inserted in the keyway 18 of the lock, the
rotatable portion of the lock Will be moved for imparting movement to Fthe pin 16 and reciproca-ting the bolt 12 in the bore 13 to either project the 'inner-end of the bolt into one of the recesses 8 or remove the same therefrom.
From the above it will be apparent When it is desired to screw the looking drum 6 upon the bolt 11, the lock member 17 is aetuated to move the inner end of the looking bolt 12 into one of the recesses 8, thus causing the body 1 and the drum 6` to rotate simultaneously. As the drum 6 has been screwed on to the bolt 11 to the desired locking'v position the lock 17 is then actuated to disengage the looking bolt 12 from the driun 6 permitting the body member L ofthe lock to freely rotate upon the drum 6 thus preventing the entire lock from being removed from the bolt '11.
The collar 3 is provided with an annnlar recess 19 and engaged therewith isa ring 20 having an eye 21 Whereby a ohain or suitable supporting member may be attached to the lock for supporting the same in a conlit venient position vvith respect to the device to vvhieh itis applied..
n Pig. 5 have illustrated a slightly moditied form of the invention Wherein the longitndinal bore 13' of the hand grips 2' is provided With an enlarged threaded portion 22 and attached to the outer end of the lookingI bolt 12' is a threaded head 23 having a transverse slot 24 in which is arranged a pin 25 carried by the rotable looking memher 2G. This looking member 26 is rotatably inounted in the outer end of the hand grips 2' and aotuated by a predetermined type of key adapted to be inserted in the looking member` for rotating the same. From this construction, it will be apparent, that when the looking member 26 is operated, the head 23 will be moved longitudinaliy Within the threaded portion 22 causing the inner end of the looking bolt 12' to engage within one of the recesses 8' in the looking drum 6' Whereby the drum 6' and the body 1' may be rotated simultaneously. It will also bo apparent that upon reverse movement of the looking bolt 12', it Will be diseonnected from the drum 6' and permit 'rotation of the body 1' from the drum 6'.
It will be apparent from' the foregoing that I have provided a simple and inexpensive lock member which may be quickly and readily applied for preventing the removal of spare Wheels from the supporting rack provided therefor on automobiles and the device may be used equally as Well on doors and the like so as to prevent access by an Leader taining .collar threaded into the bore and f embraoing the outer end of theldrum, an annular enlarged portion on the drum at the inner' end of the main bore having cylindrioal recessesV at predetermined positions in the periphery of the enlarged portion and a looking bolt adapted to be projeoted into any of said recesses for retaining said drum in plae against movement.
2. A look of the eha'acter desoribed including a body having a bore transverselv thereof With a. reduced inner end, a looking drum arrang'ed within the bore, a collar threaded into said bore and embracing the outer end of said drum the inner end of the said drum being rotatable in the reduced portion of the bore, an annular enlarg'ed portion on the drum between its ends and rotating within the main portion of the bore` said enlarged portion having a cylindrioal reooss arranged at predetermined points in the poriphery thereof. said body having a longitudinal bore adapled to align with any one of said reoessosl` a looking bolt slidablv mounted in the last mentioned bore and manually operated means for aotuating said bolt to project one end thereof into any one of said reoesses or remove the same therefrom.
In testimony whereof I aflix my signature.
