UNITED STATES DONALD HOLT, OF CHICAGO, ILLINOIS.
LIGHTING FIXTURE AND THE LIKE.
Application filed September 30, 1927. Serial No. 223,085.
This invention has to do with certain improvements in lighting fixtures and the like. The invention has reference particularly to improvements in the construction of the brackets or fixtures by means of which the lighting fixtures are clamped to a table, post, or other suitable article of furniture.
The invention has particular reference to an improved construction of the clamping bracket which is so arranged that the arm of the lighting fixture itself can be swung around a vertical post or pivot so as to bring it into the proper position.
One object of the invention is to provide a type of clamp which may be very cheaply manufactured and which may be made of rugged construction.
Other objects and uses of the invention will appear from a detailed description of the same which consists of the features of construction and combinations of parts hereinafter described and claimed.
In the drawings:
Figure 1 shows a side elevation of a lighting fixture mounted upon and swivelly connected to a clamping bracket embodying the features of the present-invention;
Fig. 2 shows an enlarged detail view of the clamping bracket of Fig. 1 together with the arm swivelly connected thereto, the figure being partly in section;
Fig. 3 shows a view of the bracket looking at right angles to Fig. 2;
Fig. 4 shows an enlarged detail section through the clamping block of Fig. 2;
Fig. 5 shows a'side elevation of a modified type of construction of clamping bracket intended to be attached to a post such as a bed post, etc.;
Fig. 6 shows a horizontal section on the line 6-6 of Fig. 5 looking in the direction of the arrows;
Fig. 7 shows a side elevation similar to Fig. 5 but illustrating another modified type of construction; and
Fig. 8 shows a horizontal section on the line 88 of Fig. 7 looking in the direction of the arrows.
Referring first to Fig. 1 the lighting fixture includes the arm or arms 10 which are joined together by the pivoting connector 11. The lamp 12 has its socket 13 connected to the arms by means of another pivoted connector 14.
There is provided a clamping bracket 15 which may be readily attached to a table or other article of furniture 1.6. The arms 10 are connected to this bracket 15 by means of a pivot connector 17.
The bracket 15 is shown in detail in Figs. 2, 3 and 4. It includes casting 18 of generally U shape having the bottom lip 19 which bears directly against the bottom face of the table or shelf 16. The bracket is then carried back over the position of the table in the portion 20 which reaches outwardly a distance substantially equal to the arm 19 and then turns upwardly in the portion 21 and then outwardly again in the portion 22. Thus the bracket itself consists of a series of steps which recede from the surface of the table or the shelf 16.
The portions 18, 19 and 20 are reinforced by a web 23 which serves to stiffen them and also adds to the appearance of the device.
The fixture 17 has on one side an outwardly reaching sleeve 24 which rests above the portion 22 of the bracket fixture itself. A pin 25 having an enlarged head 26, is extended through the sleeve 24 and through the arm 22 of the bracket 18. A nut 27 on the lower end of said pin compresses a spring washer 28 against the bottom surface of the arm 22, the enlarged head 26 serving to prevent the pin from pulling entirely through.
The result is that the sleeve 24 may be turned with respect to the bracket 18 into different positions and the amount of friction generated by the spring washer 28 may be suflicient to insure holding the parts in any selected position.
A wing nut 29 having the wing 30 is threaded down through the arm 20 of the bracket 18. The lower end of this wing nut is of reduced size as shown at 31 in Fig. 4, so as to establish a shoulder 32. A sheet metal cap 33 is swiveled on the reduced portion 31, and the said portion 31 is riveted over or upset to some extent as shown in Fig. 4 so that the cap 33 will be held in place but will nevertheless be allowed to rotate freely.
The cap 33 has the downwardly depending flange 34 which is drawn inwardly or undercut; and a block 35 of rubber or other suitable composition is held in place by this flange 34. It will also be noted that due to the compressibility of this block the burr on the lower end of the reduced portion 31 of the 37. Said bracket includes the arm 38 having.
at one side the half recessed portion 39 which accommodates substantially one half of the diameter of the pipe or other object 37. This arm 38 has at the other side the sleeve 40 which receives the pin 25 similar to the corresponding pin of Fig. 2.
There is another fixture 41 which has a half round recess 42 to accommodate the other half diameter of the pipe 37. The two sections are provided with companion ears 43 which are drawn together by screws or the like 44, the parts being suitably proportioned to readily accommodate the diameter of the pipe 37.
A wing nut 45 having the wing 46 is thread- 1 ed through a hub 47 which reaches outwardly from the fixture 41. This hub 47 is provided with socket 48 in which there is slidably mounted a clamping block 49. Said clamping block is drilled to receive theredu-ced end 50 of the wing nut, a shoulder being established in this point; and the other end of the block 49 is provided with a companion bore 51 of enlarged size establishing a recess. By. this arrangement the reduced portion 5.0 .of the wing nut may be upset as shown at 52 in the recess 51 so as to hold the block 49 in place while allowing it to turn with respect to the wing nut.
.Preferably the recess 48.0f the hub extension 47 is squared in cross section so that the clamping block 49 will not rotate when the wing nut isturned.
It will he noted that the clamping block 49 is provided with an angular depression or face which bears against the surface of the tube 37 so as to take a better bite against same. The construction shown in Figs. 5 and 6 is particularly intended for relatively large tubes or. pipes 37. That shown in Figs. 7 and 8 is intended for smaller rods and the like 53. The general construction of the arrangement of Figs. 7 ands is similar to that of Figs. 5 and 6; but the, fixture 54 does not have to be provided with the half round recess 39 for accommodating the semi-diameter of the pipe.
Instead thereof it is provided with a V shaped recess 55 againstwhich the clamping action takes place.
lYhile I have herein shown and described only certain embodiments of the features of my present invention still I do not intend to limit myself thereto except asI may do so in the claim.
I claim:
As anew article of manufacture adevice for the purpose specified comprising a pair of companion members, having cooperating V recesses adapted to receive and completely surround a post or other object to which the device is intended to be attached, a pivotal connection to one of said members, there being an outwardly extending non-circular recess in the other member terminating in a hub, a winginut extended through said hub, and a clamping block locatedin the recess and -pivotally connected to the inner end of the wing nut, Substantially as described.
