KEYHOLE-ILLUMINATOB.

To all whom it may concern:

Be it known that we, MILO P. BIXBY and JOHN B. TAYLOR, citizens of the United States of America, residin at Butte, in the county of Silverbow and tate of Montana, have invented certain new and useful Improvements in Keyhole- Illuminators, of

which the following is a specification, refer-' wherein a cradle is carried withinthe,

pocket, so as to permit a battery to be car ried. by the cradle, whereby the lifting bar which engages the cradle may lift the same for causing the battery to close the circuit for lighting the lamp.

With these and other objects in view this invention consists of certain novel combinations and arrangements of parts, as will be hereinafter more fully described and claimed.

In the accompanying drawings I Figure 1 is a side elevation of a door plate, with the knob tpartly broken away, illustrating the grip o the lift bar.

Fig. 2 is a front elevation of a door and lock, thereby showing the grip of the lift bar projecting outwardly from the door.

F1g. 3 is a central vertical section through the device.

Fig. 4 is a horizontal section taken on the line 4-4 of Fig. 2.

Fig. 5 is a fragmentary sectional view through a portion of the structure illustrating the manner in which the grip of the lift bar projects outwardly.

Fig. 6 is a transverse section through the cradle showing the lift bar in elevation and Specification of Letters Patent.

further object of this invention Patented Nov. 12, 1918.

Application filed. July 19, 1917. Serial No. 181,612.

illustrating the manner in which this lifting bar engages the cradle.

Fig. 7 is an enlarged detail perspective view of the cradle.

Fig. 8 .is an enlarged detail perspective view of the retaining plate.

Fig. 9 is an enlarged detail perspective view of the liftin bar.

- Fig. 10 is a sectional view through a ortion of the bar. illustrating an elevation in a slightly modified form, in the manner in which the lamp is mounted.

Bv referring to the accompanyi drawings by numerals it will be seen t at the door 1 is provided with a usual lock 2, carried adjacent and above the rectangular pocket 3, formed to communicate with the forward edge of the door 1. The usual plate 4 is carried upon the door 1 as shown in Fig. 1, and is provided with the usual key hole 5, formed in alinement with the key hole 6, formed in the lock 2. The door 1 is provided with a slot 7 and projects in alinement with the slot 8, formed through the plate 4.

In the preferred form the lam 9 has its socket 10 projecting through the ower portions of the lock 2, as shown in Fi 3, so

as to be carried by the plates 11, in this manner it will be seen that the lamp 9 by being (positioned within the lock 2 will be carrie adjacent the key holes 6 and 5, whereby when the lam is illuminated the key holes will also be il uminated for facilitating the insertion of a key thereinto.

The cradle comprises a base 12, having a curved elongated back'13, while the arallel side flanges 14 are formed upon the ase 12 projecting thereabove, and extending along the side edges of the back 13. This cradle is positioned within the pocket 3, formed within the door'l and carries a battery 15. At this time the closure plate 16v is positioned upon the door 1 so as'to fit over the upward outer portion of the pocket 3. This closure plate 16 is provided with an opening 16' formed therein, through which the screw 17 extends for fixedly retaining the closure plate 16 in a set position upon the door 1. A stem 18 is fixedly mounted upon the plate 16, whilethe retaining plate 19 isfixedly mounted upon this stem 18. This retaining plate 19 is bent along its longitudinal axis so as to be partially circular n cross section, whereby it ma conform in contour to the shape of the attery 15, so as to fit upon the battery.

By referring particularly to Fig. 3, it will be seen that when the closure plate 16 is in a set position upon the door 1, the outer end of the base 12 of the cradle will bear against the closure plate thereby forming a guide for the lower portions of the cradle. It will also be noted at this time that the battery 15 will be held upon the cradle, since the back 13 will bear upon one side of the battery and the retainingplate l9, Wlll bear upon the opposite side of the batteryywhfle the flanges let will hold the battery against side displacement.

A lift bar 20 is elongated and has a foot 21 formed upon its lower end, The 1ntegral grip 22 is formed upon the upper end of the lift bar 20, and this grip 22 projects toward one side of the lift bar in the opposite direction of which the foot 21 extends. The foot 21 extends beneath the base 12 of the cradle, as shown in Fig. 6, while the lift bar 20 projects upwardly beside the bar and lock, as shown in Figs. 3 and 5, whereby the grip 22 projects outwardly through the slots 7 and 8.

The battery 15 is of course provided with the usual contact finger 23 and contact tongue 24.

When this key hole is in operation, it will be noted that the battery will be carried upon the cradle in the manner above specified, adjacent the lower portions of the pocket 3, when, however, it is desired to illuminate the key holes 5 and 6, the operator pulls the grip 22 toward the upper ends of the slots 7 and 8. This action will lift the lift bar 20, thus, causing the foot 21 to lift the cradle. As the cradle is lifted it will be, of course, obvious that the battery 15 will be moved upwardly since the retaining plate 19 will hold the battery upon the cradle, although permitting the battery to be lifted. As the battery is lifted, it is obvious that the contact tongue 24 will engage the lower end of the socket, which is shown in Fig. 3, while the contact finger 23 will come into engagement with the plate 11, thus, closing the circuit. As the lamp 9 is illuminated the rays of light projecting therethrough, will illuminate the key holes 6 and 5 and facilitate the insertion of a key into the key holes.

By referring particularly to Fig. 10, it will be seen that a slightly modified manner of acquiring the lamp is employed, where it is impossible to position the lamp within the lock, or when the key hole is so small as to prevent the lamp from being positioned upon the interior of the structure adjacent the key hole. Under such conditions the battery is mounted in all respects similar to that shown in the preferred form, and it 15 therefore not deemed. necessary to make such a showing in Fig. 10, inasmuch as the only difi'erence is the manner in which the light is supported. The door 1 is provided with a lock2, while the Wires 25, and 26 extend to a socket 27 of the lamp 28. The lower ends of the wires or other conductors 25 and 26 are bent toprovide contact feet 29. These contact feet 29 are positioned within the path of travel of the contact fingel" 23, and contact tongue 24-, of the usual battery 15. As thelift bar 20' is lifted by means of the grip 22 it will be seen that the battery 15 being lifted will cause the finger 23 and tongue 2% to be lifted into engagement with the contact feet 29, thus, closing the circuit for lighting the lamp 28. This lamp being located at the outer surface of the door, will cause its rays of light to be projected to the key hole plate 30 for faciligatling the insertion of a key into the key From the foregoing description, it will be seen that a very eificient key hole illuminator has been produced, by means of which the operator may easily close the circuit for the lighting of the lamp, thereby allowing the key hole to be illuminated, although upon the release of the grip of the lift her, the battery and the cradle will return to their normal positions of the lower portion of the pocket formed in the door, since the retainmg plate and the closing plate will constitute guides in causing the cradle to return to its normal position, and at the same time retain the battery upon the cradle. It is of course, obvious that many minor detail changes may be made in the construction of this invention, without departing from the spirit of the same, and it is, therefore, not

desired to limit the construction of the device to the specific form, as herein shown, but to include all such forms as properly come within the scope of the invention as claimed.
