UNITED sTATEs PATENT oEEioE THEODORE SMITH, 0F CHICAGO, ILLINOIS, ASSIGNOR TO THEO. SMITH MANUFACTUR- ING- COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
ELECTRIC-LIGHT-CORD ADJUSTER. L
To all whom t may concern:
Be it known that I, TriEoDoRE SMITH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Electric-Light-Cord Adjusters, of which the following is a specification My invention relates to electric light cord adjuster-s, and has for its object to provide a new and improved adjusting device of this description.
My invention is' illustrated in the accompanying drawings, wherein- I Figure. l is a view showing one form of my adjusting device in position; Fig. 2 is a view showing a modified construction; Fig. 3 is a view of the device shown in Fig. 2, while the parts are being moved to adjust the length of the cord; Fig. d isa view showing the eyelet through which the adjusting cord passes; Fig. 5 is a side view'of the adjusting block; Fig. 6 is a top view of the device shown in Fig. 5; Fig. 7 is a view similar to Fig. d, showing a niodilied construction; Fig. 8 is a sectional viewon line Like letters refer to like parts throughout the several figures.
@ne of the objects of my invention is to provide a cheap, eflicient, satisfactory adjusting device for suspended electric lamps used in connection with flexible conductors.
In Fig. l l have shown a simple forni of the device. In this figure the electric lamp A is suspended by a braided flexible cord, B. An adjusting block, C, is associated with the cord, and is provided with two inclined openings, C1 and C2. These inclined n openings pass through the block in an angular direction, the edges of the openings on one side being much closer together than the edges on the opposite side. The conductor or cord is threaded through these openings so that the loop D is opposite the side of the block where the openings are the most widely separated. Under normal conditions the block is in the position shown in Fig. 1, and binds the cord so as to hold it from sliding, thus permitting the cord to be lengthened or shortened by changing the amount of cord in the loop D. l/Vhen it is desired to raise or lower the lamp the block is moved toward the horizontal position and the cord slid therethrough. When released Specification of Letters Patent.
Patented A1103 6, 1912.
Applicaton'led October 31,1904. f Serial No. 230,647.
the block moves to the position where it binds the cord and thus holds the parts in this new position. In Figs. 2 and 3 I have shown a construction adapted to be v`used where the cord is very'long, that is, where the cord is of such length that it is diiiiciilt to reach the block to adjust it. In such event I provide the block with a flexible controlling device having one end,y E, connected to one end of the block C beyond the opening, and the other end, F, connected to the other end of the-block, beyond the open ing. The block is provided with openings beyond the openings C1 and C2, and the end E of the controlling device is preferably -looped about the conducting cord B as shown. rlhe block can be adjusted. by
vmeans of this flexible control-ling device. If, for example, it is desired to raise the lamp, this may be done by pulling down upon the part G of the controlling device.
This puts a tension upon the part E and lifts the block as shown in Fig. 3, permitting it to slide upward to the desired point. When the desired adjustment is secured, the controlling device is released and the block takes the position shown in Fig. 2, and clamps the cord. lll/'hen it is desired to lower the block it is only' necessary to pull upon the part F of the controllinea device. rlhis will lower the block. rllhe flexible controlling device passes over a suitable guide,
which guidemay be attached to the ceiling,
In order to make the or other fixed part. device self-contained, however, I prefer to provide the cord itself with the 'guiding device. This may be accomplished by 'placing between the strands of the fiexible cord a spool or eyelet, H, as shown .in Fig. d.
This spool'can be readily placed in position at any desired point, and when in position the controlling device may be threaded therethrough, the spool acting as the guide therefor.
The block C may be made of one piece, as shown in Figs. 5 and 6. In this event it must be placed in position before the lamp is attached to the cord, or the cord connected to the source of electric supply.
In Figs. 7 and 8 ll have'shown a device adapted to be readily attached to the cord after the cord is in position. In this construction the block C is quarter cut that is, split in a diagonal direction, as,` for eX- ample, along the line I, Figs. 7 and 8. The M0 IOC seen that extremely flexible cords two parts are'then fastened together by a single screw, il. lt'will be seen v'that by this construction the two parts may be separated, and the cord looped, and the two parts then brought together and clamped with the single screw,-J. By means of the diagonal cut a single screw is all that is required to securely clamp the parts together and prevent any relative movement thereof.
each end thereof, and through which thel cord is looped, said holes extending through that port-ion of the block which represents i ,its lesser dimension and inclined in opposite directions in the plane of its greater dimension so that the distance between their edges on one side is greater than the distance between their edges on the other side, the loop of the cord being on the side where the distance between the edges of the holes is the greater, said holes being fixed with relation to each other, t-he position of the block between the holes fixed with relation to the portions on the opposite sides of said holes.
2. rlhe combination with a flexible cord of a block having two holes through which the cord is looped in slidable relation there# to, a flexible controlling device connected to each end of said block, vand a guiding de- Losenei.

3. The combination with a flexible cord of a block having two holes through which the cord is looped in slidable relation thereto, said holes inclined in opposite directions with the loop on the side of the block where the holes are more widely separated, a flexible controlling device connected with said block beyond the holes therein, and aguiding device for said flexible controlling device located above the block.
4. rllhe combination with a flexible cord of a block having two holes through which the cord is looped in slidable relation there to, said holes beingV inclined in opposite directions with ythe loop on the side of the block where the holes are more widely separated, a flexible controlling device 'connected with said block beyond the'` holes therein, an eyelet located between the strands of thelexible cord above the block and through which said flexible controlling device passes.
5. An adjusting device for flexible cords, comprising `a lblock free from clamping parts and made up of two solid sections, having inclined meeting faces which extend from one side of the block to the other, a single screw passing through the block and through both of said inclined faces to fasten the parts together, said block havingtwo inclined holes inclined in opposite directions and passing therethrough, said holes formed by passages in the meeting faces when said faces are brought together.
