- This invention relates to flash lights of that type adapted to be carried in the pocket so as to bealways conveniently available for use, and the invention has for its general objects to provide a flash light in the form 0f a novelty, in that it simulates a watch, pedometer, ammeter, voltmeter and other watch shaped instruments, the case of the device serving not as a housing for the usual apparatus embodied in the instruments above referred to, but an electric cell, lamp and circuit contacts are arranged in the casing, so that by the pushing of a button the lamp can be lighted.
- a further object of the invention is to provide a novel arrangement of lamp, pushbutton contacts and cell within the narrow compass of an ordinary watch case, and at the same time provide a cell of considerable capacity compared with the available space for its storage.
- a further object of the invention is the provision of a push-button switch which takes the form of the stem of the watch or instrument the device simulates, and by the pushing of the stem the circuit of the lamp is completed, and if it is desired to maintain the circuit completed for a considerable length of time the usual ring of the watch or other instrument can be so engaged with the knob ot' the stem as to keep the latter pressed in a closed circuit position.
- Still another object of the invention is the provision of an electric lamp Within the casing and normally concealed when the cover of the casing is closed, and which is adapted to be automatically lighted when the stem ot' the device is pressed in to unlock the cover, which latter springs open just like thel cover of a watch ⁇ such a device affording amusement. in that'when the per- Y son carrying the watch is asked the time he may take out the device, and pretend to open it as an ordinary Watch is opened, and instead of a timepiece being revealed, a
- the device can perform the usual service of a flash light.
- Figure 1 is a plan view of the flash light novelty in the form of a closed watch, the cover of the watch being open to show the internal arrangement;
- Fig. 2 is a. section on the line 2 2, Fig. l;
- Fig. 3 is a view of a modified form, wherein the cover automatically springs open when the stem of the device is pressed;
- Figi is a section on the line f-i, Fig. 3;
- Fg. 5 is an edge view of the watch, showing the manner in which the same is held to operate the push-button;
- Fig. 6 is a perspective view of the dry cell.
- A. designates a casing which in size and shape resembles an ordinary watch. and this casing is provided with a suitable cover l, preferably, although not necessarily, fastened to the casing A by a hinge 2. Attached to the casing is a barrel B' in which is a slidablestem l, and on the stem is a knob 5, and on the barrel is a pivoted ring 6. These parts 23, l, 5 and 6 are of the saine appearance as the stem construction of a watch, so that in its external aspect the article simulates a watch, or any other instrument of the pocket type.
- the casing A and cover l constitutes the body of an electric flash light, and the circular wall 7 of' the casing has a threaded socket 8 for receiving a small electric lamp 9 which screws into the socket.
- the base of the lamp having a central contact 10 which is adapted to engage a spring ⁇ contact l1 ⁇ and also having a threaded shell contact 12 which is grounded on the casing A, which is of metal.4 and the filament 13 of the lamp has its terminals connected with the contacts 10 and l2.
- the bulb of the lamp is preferably Hush with the circular wall of the easing so as not to be liable to injury.
- the current is furnished by a dry cell B made llO up otl units suitably bound together in the usual manner.
- the lamp is diamctrically (-.pposite from the stein l, and the cell is disposed intermediate the stem and the lamp, and the greatest length ot' the cell is transverse to the diametrical line in which the stein and lamp are located.
- a cell of maximum capacity is provided for the available space within the casing A.
- stops or abutments 1t and 15 are arranged in the easing, as clearly shown in Fig. 1.
- rihe terminal 16 ot ⁇ the cell has soldered or otherwise secured thereto the spring contact 11, which latter is an L-shaped strip of nietal projecting laterally t'roin the terminal 16. and thence along the side of the cell.
- the other terminal 1T of the cell is provided by cutting an opening 1S in the paper cover 1t) of the cell and applying a drop of solder to the metal surface exposed by making the opening 1S.
- This drop ot' solder or terminal 17 is directly in line with the inner end ot' the stem t. so that by pushing the stein inwardly the circuit ot' the cell and lamp is completed.
- the barrel l is hollow' and contains a spring 20 which presses on the knob 5 to which the stein l is fastened and consequently b v pressing the knob 5 inwardly the circuit is completed.
- a convenient method ot' holding the flash light and operating the push button switch is shown in Fig. 5, where the ring G is grasped between the thumb and first finger While the thumb is pressing on the knob or push button 5.
- the push-button can be held pressed by engaging a cross-bar 21 on the ring 6 with a notch 22 in the knob 5, as clearly shown in Fig. 2.
- the lamp 9 is normally concealed within the casing A of the device, and this lamp is screwed into a socket 8 which is fastened to and electrically connected with the casing A.
- the cell B is arranged in the casing rcversely to the arrangement of Fig. 1 and the spring contact 11 is in engagement with the stein l, and the terminal 17 has a laterally extending L-shaped contact strip 17 which extends under the socket S and e11- gages the central contact of the lamp 9. as clearly shown in Fig. l.
- the cover 1 is adapted to be held closed by a catch 23 on the stem 'L. and by pressing the stem inwardly the catch is released. so that the cover 1 will fly open. due to a spring Q4 incorporated in the hinge 2 between the cover and easing. Normally the stem 4 is separated from the contact 11', and when the stem is pressed inwardly the cover will spring open and the lamp will be simultaneously lighted.
- the construction of the cell is shown in Fig. C.
- the two units b and b each comprise a metal casing 25 which forms one electrode and contains the active material, and centrally disposed within this cylinder :25 is the other electrode '26.
- the electrode :26 of one unit is connected by a wire 2T with the cylinder of the adjacentunit. the two units being separated by a strip ot' insulation 28. and the covering 19 serving to hold the units together.
- the other electrode Q6 forms the terminal 16 to which the spring contact 11 is connected.
- a flash light comprising a metallic casing. a stem barrel fastened to the casing, a stem movable in the barrel and forming a switch contact, a knob on the outer end of the stem. a. rectangular battery in the casing and having a contact adapted to be engaged by the stem ⁇ a lamp disposed in the easing between one side of the battery and the edge ot the casing and having a terminal grounded on the latter. a contact engaging the other terminal of the lamp. and a ring attached to the barrel and forming a grip member.
