No. 578,394. Patented Mar. 9, 1897.
UNITED STATES PATENT OFF CE.
JOSEPH J. DUNN AND JOHN W. REGAN, OF BOSTON, MASSACHUSETTS.
-MANIPULAT|NG DEVICE FOR INCANDESCENT LAMPS.
SPECIFICATION forming part of Letters Patent No. 578,394, dated March 9, 189'?- Applieation filed March 9, 1896- Renewed February 4, 1897. Serial No. 622,025. (No model.)
To all whom it'may concern:
Be it known that we, JOSEPH J. DUNN and JOHN W. R EeAN,citizens of the United States, and residents of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Manipulating Devices for Incandescent Lamps, of which the following, taken in connection with the accompanying drawings, is a specification.
This invention relates to improvements in manipulating devices for incandescent lamps; and it has for its object to easily remove and attach the lamp from and to its socket, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein Figure 1 represents a longitudinal section of the invention, showing it in position on an electric incandescent lamp. Fig. 2 represents a side elevation of the invention, shown as applied to a lamp located at an angle to the handle of the instrument. Fig'. 3 represents a side elevation of the upper portion of the device, showing the adjusting-nuts for holding the jaws in inclined positions. Fig. 4 represents a side elevation of the lower end of the rod, and Fig. 5 represents a longitudinal section on the line 5 5 shown in Fig. 4.
Similar letters refer to similar parts wherever they occur on the different parts of the drawings. j In the drawings, A represents an' electriclamp socket, and B represents the glass bulb of the lamp with its head I), as usual.
The device for removing the lamp B from the socket A and connecting it to the latter is constructed as follows: It consists of a pair of preferably perforated or ring-shaped jaws O G, provided with internal soft linings or cushions O O, as shown in Figs. 1 and 2. The jaws O O are pivoted at O O to a shell or case D, as shown. Above the fulcrum O" O are pivoted to the jaws O 0 ate 6 the links F. E, the lower ends of which are pivoted at f to a rod F, guided in the case or shell D and normally forced upward by the influence of a spring G for the purpose of holding the jaws O C expanded when not in use.
To the lower end of the shell or case D is attached the upper end of a preferably duplex coiled spring H, the lower end of which l is secured to a tube or pipe I, which may be made in one or more parts connected together in a manner similar to that of fishing-rods, so as to reach lamps at any desired distance from the place Where the operator is located.
To the spring-pressed rod F is attached a cord K, the lower end of which is preferably secured to a ratchet-wheel L, pivoted at the lower end of the rod I, as shown in Figs. 4 and 5. Said ratchet-wheel is provided with a handle or arm L, by which it may be manipulated for the purpose of pulling the cord K downward and thereby causing the jaws 0-0 to be brought in contact with the lamp 13 during the operation of attaching or detaching the-latter to and from its socket A.
In engagement with the ratchet-wheel L is a spring-pressed pawl M, provided with a handle or knob m, which, when pressed upward, releases the tension on the ratchetwheel L and thereby causes the expansion of the jaws O C by the agency of the spring G, as shown in Figs. 1, 4, and 5.
On the case or shell Dis loosely journaled a ring N, to which is pivoted a link 0, pivotally connected in its lower end to a ring P, sliding on the spring H, as shown in Figs. 1, 2, and 3. p
To the link 0 is pivotally connected a link Q, the lower end of which is pivotally connected to a. ring R, sliding on the upper end of the tube I, as shown in Figs. 1 and 3.
To the upper end of the link 0 is attached a cord or string S, guided in an eye on the ring R, by means of which the spring H may be bent so as to cause the clamps O O to be held in an inclined position relative to the position or inclination of the lamp B that is to as shown in Fig. 3.
Instead of bending the spring H by means of the string S we prefer in practice to make an external screw-thread 2' on the upper end of the pipe I, on which are adjustable a pair of nuts 'i i, one above and one below the ring be attached to or removed from the socket A,
their sockets or removing them therefrom the spring H is first bent to the proper angle for reaching the lamp, and this may be done either by pulling on the string S or by adjusting the position of the nuts t" 'i on the screw-threaded upper portion of the tube I, after which the central cord K is tightened by turning the ratchet L in the direction as shown by arrow in Fig. 5, by which the clamps O C are caused to hold the lamp B firmly between them, when by turning the tube I said lamp may be r0- tated for connection or disconnection to and from its socket without the need of ladders or steps usually employed for manipulating the lamps by hand.
Having thus fully described the nature, construction, and operation of our invention, we wish to secure by Letters Patent and claim- 1. The herein described incandescentlamp-manipulatin g device consisting of a pair of pivoted expansion-jaws, pivoted to a case or shell, a flexible shaft or spring attached to said shell, a spring-pressed expander-rod arranged within the latter and links connecting said rod to the jaws and means substantially as described for closing and adjusting the position of said jaws, as and for the purpose set forth.
2. The hereindescribed incandescentpressed expander-rod, and links pivoted to said rod and jaws, a tubular rod or stem and a flexible connection'between said stem and jaws, a take-up ratchet-wheel located at the lower end of said rod and a cord or suitable flexible connection between said expander and ratchet-wheel substantially as and for the purpose set forth.
3. The herein described incandescentlamp-manipulating device, consisting of a pair of pivotal expansion-jaws, a tubular handle and intermediate flexible connections, a link 0 pivotally connected to the jaw-holder and guided on the flexible connection, a link Q pivoted to the link 0 and pivotally connected to a ring R adjustable on the handle substantially as and for the purpose set forth.
4. In a manipulating device for incandes= cent lamps in combination, a pair of expansion-jaws mounted upon a flexible shaft, a rod or handle attached to the latter and means for closing said jaws against the lamp, and holding them in proper position relative to the lamp as herein set forth and described.
In testimony whereof we have signed our names to this specification, in thepresence of two subscribing witnesses, on this 7th day of March, A. D. 1896.
