Description
.waited gaat@ @anni @Wina Leners .Patent No. 97,024, dated Note/mbsf 23, 1869.
IMPROVED KEY-GUARD.
The Schedule refen-ed co in :these Letters Patent and making part of the same.
To all whom it may concern.-
the following is a full, clear, and exact description thereof, which will enable others skilled in the art to Inakeand use ,the same,.reference being'Y had to the accompanying drawing, forming part of' this specification.
This invention relates to improvements in devices for guarding the keys or knob-Shanks of lpocks from being turned by bnrgla'rs 'or others, to forcibly open the locks from without, by the application of nippers to the shanks of thekeys, through key-holes, or other means of turning either the keys or the knob-Shanks.
The invent-ion consists in a slide, provided with two projecting flanges, which grasp the shank of the knob or key, a cent-ral tongue, which enters a perforation in the said shank, a cap, and a grooved guide, all constructed and arranged as hereafter described.
A slide, with a pin, to run int-o a hole in the shank, and a sliding recessed plate, which grasp the squared shank, are separately old, and I do not design to embrace thes'e spechc devices in my invent-ion.
Figure l represents a side elevation of a lock-case, showingr the application ot' my improved guard to -the knob-Shanks.
A represents the knob-shank. in rectangular crosssection, and having a hole through its transverse axis.
B is the sliding guard, having a notch in the end, corresponding to the cross-section of the key, and a pin, G, projectingr from the end-wall of the notch.
This slide is arranged either on the inner lock-face or on the inner side ofthe door, or a plate thereon, in guides D of any suitable kind of shape, to slide to and from the shank, in the notch adjusted to take over the shank of the knob, and the pin, to take into the hole in the shank, when said shank stands in the normal condition with the bolt shot.
E is a cap, fixed to the door, door-plate, or lockplate, for thereceptiou of the end of the slide, to hold it against any eiorts Whih may be made to force the slide away, by driving rods against it from the outside, through the holes along the shanks, or through the key-holes, when applied to the-keys.
These slides may have any means of'fastening, against being shoved back. For instance, the knobs E may be caused to drop or screw into a hole in kthe plate behind the slide, or pins may be passed through holes in the slides andthe plates, or in holesin plates behind the slides, or catch-buttons may be pivoted to the rear ends` of the slides, and arranged t0 drop' into holes iu the lock-case, door, or door-plate behind the slides.
Having thus described my invention,
I claim as new, and desire to secure by 'Letters Patent- A lock, provided with a perforatedv spindle, A, a slide, B, with flanges, and a pin, C, upon one end, a cap, E, and a grooved guide, D, all constructed and arranged, with respect to each other, in the manner described.
