yApplication -ledoctober 14,1922. Serial No. 594,441.
My .present invention relates morelparticularly to that class of locks which are-ap- -plied to the transmission lever-to enablethe `user of a machine to prevent use thereof by an unauthorized person. Among the objects of this invention are to produce a new and more effective actuating mechanism for `the lock plunger in astructure ofthe character described; to so house thefactu-ating spring of the locking member asto minimize the danger of its vvgetting'out vof'order; to dispense, so far as possible, withopenings from the exterior to the interior of the locking member in order to minimize to the utmost any possibility `of tampering withthe lock whenlocked; and such further objects, advantages, and capabilities als will later more fully appear.
My invention further resides inthe combination,-construction and arrangement of parts, illustrated in thel accompanying dra-wing, and, while I have shown therein a preferred embodiment I desire the same-to be understood as illustrative .only andinot `as limiting my invention.
In the accompanying drawing, AFig. v1-is a broken sectionalelevation showing what I now consider thepreferred embodiment of my present invention. Fig. 2 is a Similar view showing the operative parts in a different position. Fig. 3 is a sectional plan view Substantially along the plane indicated by the line 3 3 Fig. 1. Figs. 4 and 5 are perspective views of the lock cylinder and lock plunger, shown in elevation and plan in the preceding views.
Referring more in detail to the annexed drawing, 1 denotes the transmission housing and 2 the transmission lever pivoted in the housing as is usual in structures of this kind. Surrounding and secured to the transmission casing 1, by means of adjustable securing means 4, such as screws or pins, is a sleeve 3 which co-operates with the lock- L ing member 5 to prevent the transmission lever 2 from being actuated. Adjustable members 6 pass through the sleeve 3 and abut against the transmission casing 1 so that the sleeve may be properly positioned, laterally, with respect to the transmission lever. After screws 4 and 6 have been properly adjusted they are cut olf iiush with the surface so as to make it impossible to laterally remove the sleeve 3. This sleeve has .in
a its normally upper end an aperture having ran-inwardly'inclined beveled surface 7, with which co-operates a similarly 'bevelled surface on the normally Vlower :face of the locking member V5.
The locking member is provided on one?4 side witha project-ion 8 having a bore ;exktending :therethrough and into 'the Vhollow interior ofthe v locking member. This ibore 9 serves as a housing for a lockingplunger 10 and a lock cylinder 11,-the fformerfhaving a projection 12 extending from-the forward face thereof, and adapted to-.engage in-notch 1,3 in the periphery of `a lock sleeve 4'14. This ylock sleeve 14 is longitudinally aperthe purposeof which'isto-normally hold the locking member 5 4in raised position, which it will-do whenlockingplunger is .withdrawn so that projection 12 no longer/engages notch 13. Locking `member 5,-fitting Sleeve 14 closely, except for .a .groove 18,
`slides freely 'thereon under the influence of spring 17in one direction, or of pressure exerted thereon in the opposite direction. i A
projection 'or Yscrew 19 eitends outwardly from Sleeve 14 into groove 18 to prevent relative rotation of the sleeve and the locking member 5, while a co-operating projection or screw 2O extends inwardly to engage with projection 19 to limit the upward movement of the locking member when plunger 10 is withdrawn. It is preferable that the notch 13 shall be in the form of a groove having its upper edge or face at substantially a right angle to the axis of the sleeve and its lower edge or face having inclination thereto such that downward pressure on member 5 cannot cause plunger 10 or projection 12 to be bent. The lowerv face of projection 12 is inclined also to co-operate with the inclined lower face of the notch or groove 13.
A pair of pins 20, surrounded by springs 21, pass through apertures 22 in the locking plunger 10 which slides freely on these pins. Another aperture 23 is provided in plunger 10 for the reception of a projection 24 from the lock cylinder, which projection carries a stem 25 on which is rotatably mounted a roller 26. It will be clear that, as the lock cylinder is turned, the projection 25, 26, co-
operating with inclined face 27 of the locking plunger, Will cause the plunger to be ret-racted from its locking osition so that lock member 5 will be re eased and permitted to move upwardly under the influence of spring 17.
In order to prevent this lock from being tampered with, the parts are, so far as practicable, formed of steel, Which will be sufficiently hard to render it next to impossible to cut the same by such means as is ordinarily used for this purpose.
It is of course understood that the specific description of structure set forth above may be departed from Without departing from the spirit of my invention, as set forthin this specification and the appended claims.
Having now described my invention, I claim l. In a transmission locking mechanism, a sleeve having a bore in which is Secured a transmission lever, said Sleeve having a notch in the periphery thereof for the reception of a lock plunger, and a recess in Aone end surrounding the bore of the sleeve for the housing of an actuating spring, a spring housed in said recess, and a lock member enclosing and slidable on said sleeve and serving as a closure for said spring housing, said spring adapted to move said lock member from locking position.
Q. In a transmission locking mechanism, a sleeve adapted to be secured to a transmission lever, said sleeve having a notch in the periphery thereof for the reception of a lock plunger and a depression in its upper end surrounding the longitudinal aperture of the sleeve for the housing of an actuating spring, a spring housed therein, and a lock member enclosing and slidable on said sleeve and serving as a closure for said spring housing, said spring adapted to move said lock member from locking position, said member, aside from the opening for the reception of the transmission lever, beingim.- perforate on its upper surface.
3. In a lock, a relatively fixed notched sleeve adapted to be secured to a transmission lever, said sleeve having a peripheral groove therein, a locking member slidable longitudinally on the 'sleeve and having locking means to engage the notch of said sleeve, said loc-king member having a longitudinal groove interiorly thereof, and co-operating projections on the exterior of the sleeve and interior of the locking member respectively adapted to engage \vithin the longitudinal groove to limit the relative longitudinal sliding movement of the sleeve and locking member and prevent said locliing member from rotating.
1i. In a transmission locking mechanism, a sleeve adapted to be secured to a transmis- Sion lever, said sleeve having' a notch in the periphery thereof for the reception of a lock plunger, and a depression in one end surrounding the longitudinal aperture of the sleeve for the housing of an actuating spring, a lock actuating spring housed therein, and a lock member enclosing and slidable on said sleeve and serving as a closure for said spring housing, in combination with an adjustably mounted sleeve surrounding` and secured to the transmission housing and having in its upper end an opening for the reception of the lock member when the latter is moved into locking p osition.
In Witness whereof, I hereunto subscribe my name to this specification.
AUGUSTUS o. SAXTON.
