LAMP STAND.

Application filed August 7, 1922. Serial No. 580,035.

This stand is particularly designed for supporting an electric lamp in a studio or other enclosure and has for its object to provide a light and easily movable stand, one which can be adjusted to any height desired and one which can be folded into a compact form when not in use. Another object is to provide a stand embodying the characteristic features which will be inexpensive and easily made.

With these objects in view the invention consists broadly in providing a base and detachably connecting a fixed standard there to, and also uniting this standard and base by means of foldable braces, connecting a movable standard to the fixed one, and providing counterweights for the movable standard upon the braces and connecting them to the movable standard.

The invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter and pointed out in the appended claims.

In the drawings forming a part of this specification, F 1 is a side view of a lamp stand embodying one form of my invention; Fig. 2 is a rear view of the same; Fig. 3 is a sectional plan in the line 33 of Fig. 1; Fig. 4 is a side view of the stand folded; F 5 is a rear view of the same; Fig. 6 is a detail view of the lamp bracket;Fig. 'Zis a detail in section of the supporting standard; Fig. 8 is a side view of a slightly modified form of stand; Fig. 9 is a front view of the same; Fig. 10 is a top plan view; Fig. 11 is a section on the line 11-11 of Fig. 8; Fig. 12 is a sec-- tion on the line 12-12 of Fig. 8; Fig. 13 is a section on the line 1813 of Fig. 8; Fig. 141 is a side view of the stand folded; and Fig. 15 is a rear view of the same.

Referring to Figs. 1 to 7 of the drawings, 10 indicates a base having divergent legs which are preferably strengthened by a reinforcing rib and the base is mounted upon caster rollers 11 arranged at the ends of the legs. The base is provided with a socket member or portion 12 into which fits the lower end of a fixed standard 13 preferably of angle iron as shown, and having a guide frame and roller 14 at its upper end. A set screw 15 detachably connects the standard to the base. Inclined braces 16, 16 connect the upper end of the standard 13 with the diverging legs of the base, and as these braces are pivotally connected to the base and standard all of said parts can be folded as shown in Figs. a and 5 by detaching the standard from the socket in the base.

A movable standard 17 is arranged alongside the fixed standard and is preferably in the form of a tube pipe or rod and carries a loop eye or sleeve 18 at its upper end. The movable stand 17 has guides 19, 19 secured thereto, said guides having oblique slots 19 to receive the flanges of the angle iron stand ard 13 and by this means a sliding connection between the fixed and movable standards is established. The standard 17 is read ily moved up and down upon the fixed standard, and in order to maintain the same at any adjusted position 1 provide counter weights 20, 20, sliding upon the braces 16 and connected to the movable standard by means of chains 21 or other flexible means which pass through the guide roller frame 14 at the upper end of the fixed standard.

lamp supporting bracket 22 is detachably connected to the movable standard, said bracket having a. hooked end 23 for engaging a transverse pin 2st in the standard, and it also has a depending lug 25 through which works an adjusting screw 26, having its head bearing against the standard and which holds the bracket firmly in place as shown in Figs. 1 and 6.

The are lamp (not shown) is suspended upon the bracket arm 22. In the construction shown in Figs. 8 to 15 inclusive, there is a very slight modification of the stand illustrated in Figs. 1 to 7. The base 10 is pro vided with caster rollers and is formed with divergent legs and has the socket port-ion 12 into which fits the angle iron standard 13 and a set screw 15 is employed to secure this standard to the base. At the upper end of the fixed standard thereis a roller guiding frame 14 having a roller 1% arranged therein and connecting this roller guide frame and the legs of the base are the braces 16. A movable standard 25 carries a lower frame 26 at its roller end and is provided with a roller 27 engaging the concaved side of the angle iron standard and a cam locking lever 28 upon the opposite side of the standard locks the movable standard 25 in adjust ment and at its upper end this standard is curved over as shown at 25 and provided with an eye or loop 25 from which the arc lamp can be suspended. A cable 29 is connected to the frame 26 and the strands of this cable pass over the rollers 14* and are connected to the counter weights 30 which slide up and down upon the inclined braces 16. The movable standard is readily adjustable in order to suspend the lamp at the height desired and when not in use the stand can be folded by disconnecting the fixed standard from the base and folding the parts together as most clearly shown in Figs. 14: and 15.

It will thus be seen that I provide an exceedingly simple construction of stand, one which is capable of quick and easy adjustment and one which owing to its construction, can be cheaply manufactured and easily put together.

Having thus described my invention, what I claim is:

1. An arc lamp stand comprising a base, a standard fixed thereto, a second standard carried by the first standard and movable with reference thereto, a counterbalance and flexible connection for the movable standard and'an inclined brace for said fixed standard forming a guide upon which the counterbalance moves.

2. An arc lamp stand comprising a base, a standard detachably connected to said base, inclined brace members connecting the standard and base, a second standard carried. by the first named standard and movable vertically with reference thereto, counterbalance weights movable on the brace members and fiexible connections connecting the movable standard and said counterbalance weights.

8. An arc lamp stand comprising a base, a standard fixed with reference to said base, a second standard movable with reference to the first named standard, hinged braces connecting the base and fixed standard, counterbalance weights movable upon said braces and flexible connections between said counterbalance weights and the movable standard.

l. An arc lamp stand comprising a base, a fixed standard detachably connected to said base, braces pivotally connected at their lower ends to said base and connected at their upper ends to the fixed standard, a second standard movable vertically with reference to the first standard and guiding means for said movable standard, counterbalance weights movable upon the braces, flexible connections between the counterbalance weights and movable standard, and a lamp carrying member detachably connected to the movable standard.

5. An arc lamp stand comprising a base having divergent legs, an angle iron standard fixed to said base and detachable therefrom, a movable standard, guiding means for the movable standard and traveling upon said fixed standard, foldable braces connect-- ing the base and fixed standard, counterbalance weights movable thereon, flexible connections between the counterbalance weights and movable standard, and a guiding means for said flexible connection carried by the fixed standard.

6. In an arc lamp stand the combination with a fixed standard of angle iron, of a guide movable upon said angle iron standard, a movable standard connected to said guide, said fixed standard having a guide at its upper end with which the movable standard contacts, brace members connected to the guide at the upper end of the fixed standard, a counterbalance movable upon said brace and fiexible means connecting the guide carrying the movable standard and the counterbalance, said flexible means being movable through the fixed guide for the movable standard.

7. The combination of a base, a vertical standard detachably fastened to said base, a pair of diverging braces hinged to the upper end of said standard and parts of said base spaced from the lower end of said standard, a movable standard sliding on the fixed standard for vertical adjustment thereon, and a counterbalance connected to said movable standard.

8. The combination of a base, a vertical standard detachal ly fastened to said base, a pair of diverging braces hinged to the upper end of said standaro and toparts of said base spaced from the lower end of said standard, a movable standard guided on the fixed standard for vertical adjustment thereon, counterbalance weights slidably mounted on said braces, and l'lLr-Jblfi connectors connecting such weights with said movable standard.

9. The combination of a base, a vertical standard detachably fastened to said base, a pair of diverging braces hinged to the upper end of said standard and to parts of said base spaced from the lower end of said standard, a momble standard guided on the fixed standard for vertical adjustment thereon, counterbalance weights slidably mounted on said braces, a pulley at the upper end of said fixed standard and flexible connecting links connecting said weights with said movable standard.

In testimony whereof, I hereunto aflix my signature.
