My invention relates to improvements in bed lamps, and it consists of the combinations, constructions and arrangements hereinafter described and claimed.
An object of my invention is to provide a bed lamp which has means for directing the light to either side of a bed and for controlling the amount of light so that one of the occupants of a double bed may read, while the other person may sleep, without being annoyed by the light. The device is also designed to give light to both occupants of the bed without illuminating the room to too great an extent. 'It is also possible to enlarge the light opening of the device so that the entire room can be illuminated. The means for securing the lamp to the bed is adjustable so that the light opening can be changed to different angles, and thus throw'the light in the desired direction. It is obvious that the device can be used as a table lamp as well as a bed lamp.
A further object of my invention is to provide a device of the type described which is extremely simple in construction and is durable and efll-' cient for the purpose intended.
Other objects and advantages will appear in the following specification, and .the novel features of .the device will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawings forming a part of this application,
' in which I Figure 4;
Figure l is a front elevation of the device with portions thereof being broken away;
of a modified form along the line -5 of view of a part of Figure B is a front elevation of another 'modifled form of the invention, a portion being shown in section; and
Figure 9 is a section along the line 9-9. of
Figure 8. r In carrying out my invention I provide a cupshaped end I, see Figure l, in which I dispose a split cylindrical shell or casing 2. The casing 2 is secured to the end I and the split portion} be entirely opened.
constitutes a window 3 for permitting the light from a lamp 4 to pass therethrough. The lamp 4 is mounted in a socket 5 and the socket in turn is secured to the end I. An electric wire 6 passes through the end I and is electrically connected 5 to the lamp 4 by a pull chain switch I.
The other end of the casing is closed byga removable cup-shaped end 8 and when this end is in position itdefines the right-hand. side of the opening 3. Within the casing 2, lI ro tatably dis- 10 pose a. shutter 9. The shutter is in the shape of a split cylinder and has a length'equalto the 'length of the casing 2. The split portion ID of the shutter is of the same dimension as the split portion of the casing 2. In other words, when the shutter 9 is rotated so as to align the split portion I0 with the window 3, the window will The 'means for rotating: the shutter 9 comprises a wire ii that has aicurved portion equal to the curved portion of the shutter. One end of the wire extends radially and inwardly from the corner l2 of the shutter as shown at l3, and then the wire is bent at M so as to coincide with the axis of the shutter 9 and the casing 2.- The portion l4 extends through an opening l5 inthe end 8 and the portion is threaded at l6 for receiving a. handle ll. Itwill be seen from this construction that the turning of the handle I! will turn the shutter 9 within the casing 2. I
When the split portion In coincides with the window 3 the greatest amount of light will pass through the window. This light is sufilcient to illuminate the room in which the device isused. Figure 3 shows the shutter 9 as being provided with a large central opening l8, and Figure 1 shows this opening in registration with the windows 3. The opening, it is of such size as to permit suflicient light to pass through the window 3 so that both occupants of the bed can 40 read. This light, however, is not sufiicient to illuminate the entire room, and therefore it will be possible for another'person in the room, such as a baby, to sleep undisturbed by the light. If it is desired to cut down the amount of light it is only necessary to turn 'thehandle H for mov ing part of the opening l8 beneath the shell 2. In this simple way the amount of intensity. of the light issuing from the window 3 can be controlled at will. r
In addition to the window I8. I provide two smaller openings l9 and 20 in the shutter 9, see Figure 3. The opening l9 can be moved into registration with the wind w 3, and this opening is of such a size as to projei t light rays from the right-hand half of the casing 2, shown in Figure 1. This light will be suflicient for a person lying on the right-hand side .of the bed to read without causing the other person to be disturbed by the light. The quantity of light issuing from the opening l9 can be controlledby revolving any portion of the opening beneath the casing 2.
If it is desired that the light issue from the left-hand side of the .casing and not the. right- 10 hand side, the opening or window is brought into registration with the window 3 by the turning of the shutter 9. The intensity of this light can be controlled by moving any portion of the opening 20 beneath thecasing 2. In order to 15 direct the light rays forwardly from the openthrough the various openings when they are used.
The casing 2 is-also adjustable,- and in- Figures 1 and 2 I show hook-shaped supports 22 which 2 are removably connected to a bed 23' and the other ends of the hooks are slidably received in sleeves 24 that are carried by the casing 2. If desired the sleeves. can'have slots 25 therein.
through which screws 23 carried by the hooks 22 project. 'Wing nuts 21 "adiustably secure the hooks 22 to the sleeves. "It will be seen that the window 3 can be moved into a position to direct the light at the" desired angle with thiswarrangemen In Figures 4 to inclusive I show a modified form of the invention. In thisform the shutter 9 is dispensed with and sliding shutters 23 are These shutters close the window 3 of the casing 2, and can be extended for providing an opening 29 of any desired size through which the light can pass; It will be seen from Figures 5 and16 that the window- 3 has flanges 30 exfor providing the small opening 29 at the lefthand side of the casing 2. Figure 6 shows how both groups of shutters can be extended for positioning the opening 29 at the center of the casing. and for making this opening larger than that shown in Figure 4. In this simple manner the opening 29 can be made of any size up to the limit of the opening movement of the shutters, and can be positioned at'any place along the window 3 within the extreme limits provided by the end shutters 280.. It will be seen that the two sets of shutters 23 produce the same result as the shutter 9. The end 3 can be removed when it is desired to insert a new lamp 4 in the same length as the window'3, and is 'slidably resocket 5. This is true of the two forms of the device already described, and also is true of the third form which will now be described,
The third form is shown in Figures 8 and 9,
and the window 3 in'thls instance is closed by an arcuate shutter 38. The shutter 39 is of the ceived in guide channels 39 which in turn are secured to the casing 2. The shutter 38 may be moved for exposing any desired portion of the window 3, and in this" way the light emanating from the window can be controlled.
The arcuate shutter 33 carries"three small arcuate shutters 4054i and 42. The small shutters are disposed over smallwindows 43, 44,.and provided in the large shutter 33. The large shutter 33 carries guides 49 which slidably receive. the shutters 40, 4|.and 42.
The openings 43 and 45 function in the same manner as the openings I9 and 20, while the opening-44 takes the place of the opening I9. The large shutter and the small shutters are frictionally held in adjusted position. In 'the last two forms of -thedevice I have not shown the hook-shaped supporting members 22. In actual practice, however, the supporting thembers or other equivalent f'supportin'g means will tending along the topand bottom edges of the window. The shutters aregrouped in threes and ure'6. The shutter 29c. seeFigure 7, has flanges 3I atits top and bottom designed to receive the flanges 30. In this wayfthe shutter. 23a is secured to the. casing-2 and-closes the end 'ofthe window 3 disposed adjacent to the 'end I' and the end 9. The shutter 23a is held against movement either by friction, or it may be welded or otherwise secured in place. v p
The rear surface of the shutter 23a carries top and bottom guides 32 which slidably receive a second-shutter 281). Figure 6 shows how the shutter 23a carries a-stop '33 which will engage with a'stop '34 carried by the shutter 23b when the latter has been moved into extendedposi? tion. -The third shutter 23c is slidably-received in the curvedtop and 'b'ottomjedges 35 of-the shutter 23b. The-secondshutter 23b has a stop 33 designed to contact with'the stop IIi carried by the shutter 23c. Thestops 33L and when contacting with each other limit further movement of the shutter m.- I-have described one group of shutters and the other group is identical in construction, and therefore needs no further description. 7 Figure'4'shows how the three shutters 23,2lb' and 23co-the ri ht-hand group canbe extended be used for the- I claim: p i I 1.
