2 Sheets-Sheet f9 CKH. sPRouT ADJUSTABLE LAMP BRACKET Original Filed Sept.

PATENT CARLTON H. SPROUT, OF PHILADELPHIA, PENNSYLVANIA.
ADJUSTABLE LAMP BRACKET.
Application filed September 1, 1922, Serial No. 585,703.. Renewed May 21, 1926.
' This invention relates to adjustable electric lamps, and the principal object is to produce. a device of this nature which may be instantly adjusted to any desired position or angle and which Will be automatirally held in adjusted position.
Another object is to provide simple and novel supporting means and joints permitting universal adjustment.
Another object is to produce a device of this nature having a novel arrangement of weight compensation for holding the devices in adjusted position.
Another object is to construct a device of this nature which should be simple of construction and operation, and highly efficient for-the purpose for which it is designed.
Another object is to construct a simplified and extremely cheap and efficient knuckle joint for supporting the lamp proper.
lVith these and other objects in view,-
which will be more clearly noted as the specification proceeds, the invention resides in certain novel features of construction and combination and arrangement of parts, the essential elements of which are hereinafter fully described, are particularly pointed outin the appended'claims, and are illustrated in the accompanying drawing in which:
Figure 1 is an elevational view of my adj ustable lamp bracket.
Figure 2 is a view of a modified form of base.
Figure 3 is a perspective view of one of the knuckle joint elements.
Figure 4 is a fragmentary top plane view of the swivel device.
Figure 5 is a vertical sectional view taken on the line 5-5 in Figure 4.
Figure 6 is a transverse sectional .view taken on the line 6-6 in Figure 4.
Like characters of reference refer to like parts in all views.
Referring to the drawings in detail, 10 represents a main tubular support or pedestal of the lamp which may be provided with a. base 11 as shown in Figure 1 when the lamp is to be supported from the floor or ceiling. lVhen the lamp is to be supported from a table, bench, or the like a clamp 12 as shown in Figure 2 of the drawings may be substituted for the base 11.
Threadingly engaging the upper end of the tube 10 is a bell-shaped member 13 provided on its upper face with an annular flange or shoulder 14. A swivel head 15 is supported by the member 13, said swivel head being provided on its lower face with an annular shoulder 16 embracing the shoulder 14. A bolt 17 carrying a spring element 18 at one end passes through a portion of the head 15 and through a plate 19 secured in the bell-shaped member 13. The spring 18 tends constantly to hold the members 15 and 13 in close engagement by permitting the free rotation of one on the other.
An electric conduit 20 carrying the necessary electric wires 21 enters the base and passes up through the tubular stem 10 into the bell-shaped member 13 where the wirw are connected to respective binding screws 22 which pass through a disc of insulation 23 and into contact rings 24.
A block of insulation 25 is mounted in the base of the member 15 and carries contact rings 26 which engage respectively with the aforementioned Contact rings 24.
Binding posts or screws 27 connect with the contact rings 26 and to these lead wires 28 are'attached which pass up through the member 15 to binding posts 29 mounted in a vertically disposed block of insulation 30, said binding posts passing through the insulation 30 and into contact rings 31.
The vertical face of the swivel head 15 is provided with an annular shoulder 32 within which fits the annular rib or shoulder 33 of a rotary member 34. The member 34 carriesa disc of insulation 35 upon which the contact rings 36 are mounted, said contact rings being connected to binding posts 37 to which the ends of wires 38 are secured. The wires 38 pass through a conduit 39 which passes out through a side aperture 40 in the member'34.
A bolt 41 passes through the members 15 and 34 so as to hold the shoulders 32, and 33 in engagement, said bolt being provided with a spring tension member 42.
One bar 43 of a pair of lazy-tongs is securely attached to the member 34 by screws 44 or other suitable means and the bolt 41 passes through this bar and through the outer bar corresponding thereto on the lazytongs. The lazy-tongs are indicated general- 1 at 45Figure 1and have two noticeable eatures. First, they extend on both sides in Figure 3 and indicated by the numeral 50, the body being provided with four equally spaced ears-58, t e diametrically opposite ears being bent in the same direction and one pair of ears being bent in the opposite direction from the other pair. Each of the ears is provided with an aperture 52 the a ertures of each pair of. ears coming in alignment upon completing the bending operation. Two of these members 50 are secured together at 52 so as to have relative movement in a horizontal plane, the other ears of one member 50 being secured at the final ivot 53 of the lazy-tongs, and the ears 0? the other member 50 being pivotally secured to the members 49 at 54.
From the above description it will be readily seen that the entire device may be swung in a horizontal direction about the axial line of the standard 10, that it may be rotated in a vertical plane about the axis 41, that it may be extended by means of the lazytongs 45 and that the lamp 47 ma be then adjusted with relation to the work y reason of the joint made by the two membeis 50, and that in all positions the springs 18 and 42 and the counter-weights 46 will tend to hold the various parts in the adjusted positionto which they are moved. The springiness of the ears 51 is. also relied on to assist in this.
While I have described what I deem to be the most desirable embodiment of my invention, I do not limit myself to the specific details of construction of material, nor to any thing less than the whole of my invention as defined bme appended claims.
What I c '1. In an adjustable lamp bracket, the combination of a pedestal support, a bell-shaped member carried at the upper end of said pedestal support and comprising a pair of sections connected for rotary movement, an upright risin from the upper rotatable section of said inn-shaped member, a second member carried b said upright and composed of a pair 0 sections one of which is rotatable relative to the other, said latter section being rotatable about an axis disposed at ri t angle to the axis of rotation of the sections of the bell-shaped member, a lazy-tong structure carried by the rotary section of the second mentioned member,
counter-balancing weights at one end of the lazy-tong and a lam structure carried at the other end of the azy-tong.
2. In an adjustable lamp bracket, the com bination of a pedestal support, a bell-shaped member carried at the upper end of said pedestal support and comprising a pair of sections connected for rotary movement, an upright rising from the upper rotatable section of said bell-shaped member, a second member carried b said upright and composed of a air 02 sections one of which is rotatable re ative to the other, said latter section being rotatable about an axis disposed at right angles to the axis of rotation of the sections of the bell-sha ed member, a lazy-tong structure carried y the rotary section of the second mentioned member, counter-balancing weights at one end of the lazy-tong and alamp structure carried at the other end of a lazy-tong, and electrical circuit closing switches carried by said bellshaped member and the second member supported from the upright on the bell-shaped member.
In testimony whereof I affix my signature.
CARLTON H. SPROUT.
