0. SMITH. APPARATUS FOR DETAGHING ELECTRIC LAMP BULBS.
Patented Apr. 21,1896.
INVESTOR v AN DREW BDHMIAM. PHO'ID-UmuWASHINGTOKRC.
NITED ATENT OFFICE.
OLENY SMITH, OF DETROIT, MICHIGAN.
SPECIFICATION forming part of Letters Patent No. 558,573, dated April 21, 1896.
Application filed October 7, 1895.
Lanip Bulbs; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to improvements for detaching and replacing electric lamps when located near the ceiling or any other place ordinarily inaccessible.
The invention will be readily understood by reference to the accompanying drawings and specification.
In the drawings, Figure l is a sectional view of my improved lamp-detacher. Fig. 2 is a variation of the same. Fig. 3 is a detailed view of a clamp for holding the dust-cloth to be used in connection with said detacher.
In the drawings, A represents a handle.
13 is a head secured to the handle in any suitable way.
0 is a swivel connection, which may be held in any position by the set-screw Q. Mounted in the swivel connection is a collar D. The
springs E are secured in any suitable manner i to a head-piece D. This head-piece is held in the collar D by means of the set-screw e, which also serves to secure one end of the flexible shaft F in the head-piece D. One end of the flexible shaft F is engaged with the rod G. The rod Gterminates in a crankarm Gr. screw 61.
E represents rubber tubing slipped over the springs E to afford frictional engagement with the lamp-bulb during the act of removing or replacing the bulb.
The operation of the device is as follows: We will suppose the lamp to be removed to be in a vertical position. The operator forces the springs over the lamp-bulb, and by turning the crankarm G the springs coming into contact with the lamp-bulb will cause the same to turn by means of the connection through the flexible shaft and rod G.
If the The collarD is held in place by the Serial No. 564,855. (No model.)
lampis located in a horizontal plane, or in fact any angle, it is only necessary to adjust the swivel connection 0, locating the same in a position to engage the lamp, then look the same by means of the set-screw 0, when the lamp can be readily engaged and the act of detaching and replacing the lamp be carried out. The construction shown in Fig. 2 involves the same principle; but in this case the swivel connection is dispensed with. The flexible shaft F in its normal condition is bent at an angle as shown and connected directly with the handle A by means of the ferrule a, or any suitable engagement, the other end of the shaft being connected directly with the springs E for engaging the lamp. If the lamp to be detached is in a vertical position, it can be readily seen that the springs can be forced over the bulb by holding the device at the proper angle, and when once engaged over the bulb the flexible shaft can be forced into line with said handle, and by turning the same the lamp can be detached or replaced. It will be found that the angle shown in the variation referred to will adapt itself to the majority of positions in which electric lamps are located.
I provide a bag H of chamois or other suitable material, which may be secured in any suitable manner to the springs E, as shown in Fig. 2. It will be found very convenient in wiping or dusting the bulbs by simply slip.- ping the bag over the bulb and rotating the same around the bulb. The lamps can then bequickly and thoroughly cleaned.
Fig. 3 shows a clamp for holding a dustcloth, and consists of the jaws I 1, preferably shaped so as to adapt themselves to the contour of the springs E. They are pivoted as shown at 2', and at one end is located a set-screw i. J represents the dust-cloth. By placing one end of the dust-clothJ between thejawsI I, then by turning the set-screw t" the jaws can be made to engage the dust-cloth, holding the same securely. It is intended to use this dust-cloth holder in connection with the lampdetacher, and it is engaged by means of the springs, similar to the electric-lamp bulbs. The dust-cloth can thus be used to clean electroliers or other places ordinarily inaccessible. In place of the rubber tubing placed over the springs E, to afford frictional engagement with the lamp-bulb, a pocket of sheetrrubber or other suitable material may be used without departing from my invention. I prefer, however, to use the tubing shown.
It is understood that I do not limit myself to the construction herein shown.
What I claim is- 1. In a lamp-detacher, a flexible shaft provided with means for engaging the lamp, and means for rotating said shaft, substantially as described.
2. In an electric-lamp detacher, a flexible shaft, springs to engage a lamp-bulb, a swivel connection adapted to engage lamps at different angles, and means for rotating said shaft and springs substantially as described.
3. In a lamp-detacher, a flexibe shaft working in asuitable handle, aswivel connection, suitable means for engaging the lamp and means to rotate the flexible shaft, substantially as described.
4. In a lamp-detacher, a flexible shaft,
springs to engage a lamp-bulb, said springs OLENY SMITH.
