. Renewed November 20, 1935 2 Claims. (01'. 70-122) This invention relates to a spare tire lock of the class wherein a bolthead or nut is received and enclosed in a multipart lock housing, the parts of which are intended to be locked against separation.

By virtue of its novel construction, this locking device is extremely simple to operate and install. It is also durable and of a rugged construction intended to resist the efiorts of unauthorized persons in obtaining separation of the parts.

It may be said that one object of this invention is to provide a locking device for enclosing and preventing the removal of a nut which in turn secures the device in position, the said lockin ing device possessing the characteristic of having a two-part housing that is held when in cooperation against separation in at least two zones. An.- other object of the invention is to provide a nutlock that will allow the manipulation. of the nut or bolt enclosed within the nut-lock housing by the fingers of the hand or some suitable tool.

It is the aim of this invention to provide a twopart lock housing, one of the parts being of such depth as to accommodate. a nut or holthead,

the other of the parts acting as a closure in mounting the locking device manipulatable to obtain jointure of the two parts in non-separable relation. The relationship between theparts of the housing is such that they are secured to- 80 gether in opposed zones, namely at the top and bottom of the assembly, a releasable lock occupy! ing the top zone so that upon opening of the lock the closure will tend to fall away from the other portion, and thus uncover the nut-head. This movement is assisted by the action of a. spring. Accurate centering of the housing in mounting the same is a matter of little or no concern to the operator since the closure may be considered as self-centered. 7

Qther obiectsyand advantageous features of this invention will be observed from the following detailed description and accompanying drawing, wherein like characters of reference designate corresponding parts, and wherein Figure 1 is a side elevation of the preferred form of my locking device.

Figure 2 is a bottom view of the device shown in Figure 1.

Figure 3 is a front elevation of the device of Figure 1.

Figure 4 is a vertical longitudinal section through the device showing the locking arrangements and the manner in which the nut is received and enclosed within the locking housing,

Figuref5 is an elevation, partly in section, disclosing the manner in which the housing parts are separated.

Figure 6 is an elevation of the back side of the closure member of the housing. 5

Figure 7 is a fragmentary view of the upper interior zone of the mounting section of the housing illustrating the downturned edge behind which the locking bolt operates. With reference to the drawing, I have shown 10 my device as being made up essentially of three elements, namely, a two-part lock housing and a locking device for preventing separation of the parts of the housing. The housing may be conveniently divided, for purposes of description, 15' into a mounting section A and a closure section B, the mounting section A being adapted to be mounted on a stud, such as that shown at C, to encompass and enclose the nut D, and the closure section B may be mounted thereon and 20' locked thereto through the provision of locking instrumentalities, generally indicated at E, carried thereby. As regards the mounting section A, this member may be a simple stamping having a deformed portion I in the rear surface that is 25 knurled as at 2 for cooperating with the walls of an aperture in the carrier bracket F, Figure 4, to prevent turning of the housing with respect thereto. The flange 3 of this stamping is provided with a rectangular aperture 4 in its bottom zone. so The marginal edge of the flange is also downturned as at 5 to present a. surface behind which the bolt of the lock may work. The mounting section A therefore practically comprises a hous-. ing or'casing for the stud or head or a bolt to be 35 lockedagainst unauthorized. access thereto by the use of my device.

Referring now to the closure member B, this part may be a die-casting of the configuration shown wherein an end portion is providedlwith it? an inwardly projecting hollow extension of larger and and smaller diameters, the larger portion 6 being'formed with an aperture or slot 8 for the locking bolt 1 and the inner portion 6a providing an inner barrel to receive the inner locking 45 cylinders of the locking mechanism or parts. This locking mechanism is of a known type invented by me and is not material to this invention because any suitable locking' mechanism may be used in lieu thereof. On the inner side of the 50 closure member B is an inset flange 9, Figures 5 and 6, from which depends a locking tongue ID to be received in the rectangular aperturefl inthe mounting section or casing A. The closure member 13 is of such construction that the flange 55 p 9 cooperates with the inside surface of the part A and the body of the closure will overlie the marginal edge of said part A so as to be substantially flush therewith. The larger portion of the hol-' 'low' extension or inner'barrel 6 of the member B accommodates the outer key'barrel H, which barrel carries the outer set of concentric cylinders or sleevesforming apart of the locking mechanism E; The key barrel Halso carries' the locking bolt 1 as shown in Figures 4 and5 most clearly,

The reduced portionlia'of the inner cylinder barrel Ghas mounted thereon and therearound a coil spring I 2 which normally tends "to push in Figure 4 when theclosure member B is placed on the mounting section or casing'Afthe spring l2 is compressed against the-wall of this latter member A and'when the lock bolt"! is. released .the spring tends to separate the parts A and B as shown in Figure 5. The locking imechanism as stated may be of .conventionaldesign, being preferably of the multiple or concentric cylinder type, each of thecylinders being spring-urged,

in one direction and being movable intolock releasing positions by means of the key K after a manner well known in this art. =Thef key barrel l l is equipped witha knurled manipulating sur face M at its outer-most portion. 'Theclosure member B is bulged in the zone [5 to accommodate nuts, studs, ,or bolt heads of varied lengths or sizes in an obvious manner. nuts or heads or studs varyin reference to different types of automobiles and'diiferent types of other appliances with which my' lock may be used. To look the closure member B on the easing'or mounting section A, said member B is moved inwardly toward the part A from the posi-.

. tion in which the member B is shown in Figure 5,

and the key barrel H is turned in a clockwise,

manner by manipulation of the knurled portion 1410f the key'barrel. II to move the lock' bolt .1 in a rightward manner to engage it behind the locking flange or web 5. I When the lockjis closed in'the above manner the spring 12. is ofdcourse compressed and tends to push outward upon the .c'losure sectionor member B. By manipulation of the key K which controls the proper-pushing of the inner Yancl outer concentric locking cylin ders G of the-locking mechanism, thekey barrel 7 l I may be unlocked andturned to the position of Figure 5 or to the'rightas shownin Figure 6,

whereby to withdraw the lock bolt 1 from its engagement with the flange or web -5 whereupon the spring [2 will tend to push the closure section B to its open position of Figure 5."; The tongue lOlwill hold the parts in the position of Figure 5 until the closuresection B is raised'to disengage the tongue from the slotor aperture 4. The operator does not have to shake'or pound outwardly on the closure member B. As shown The sizesof these the lock to cause separation of the parts; A and B in view of the use of the spring l2. Moreover, this spring is very desirable in performing the fuction of an anti-rattling spring as it maintains the parts A and B under presure such thatrattling '5 vibration of these parts is entirely prevented. It

is to beunderstood thatthe lock unit of the present invention may be disposedupon the cooper: ating parts for which it .is to be used. for locking purposes, in different positions depending upon the location of such parts and the limitations of the spaces where thelock units'may be employed. It is immaterial whether the lock "units are utilized in conjunction with stud bolts or nuts applied to bolts or the, like, because it is effective under all conditions of use with'such f members to prevent unauthorized access thereto. "Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is: V l. A tire lock'ofthe classintended'to bemount- 7 ed upon'astud andto receive and enclose'a nut on .the 'shank of the stud, which comprisesa mounting section havinga webbed. portion, said mounting section having an aperture therein,- a closure member, a lock carried by said closure member having a part for cooperation .With'the web to prevent separation of the closure with re spectito the mounting section when the said closure member is mounted thereon, a tongue formed 30 A mounting section forming an open faced casing, 40?
