Specification of Letters Batent. Pat t d 4 1914- Application filed October 31, 1912. Serial No. 728,821.

To all wh0m may concern I Be 1t known that I, JAMES C. RAMSEY, Jr.,' a citizen of the United States, residing at Andover, in the county of Essex and Stateof Massachusetts, have invented .a new and useful Lamp-Support, of which the following is a specificatlon.

This invention relates to a lamp support ing and operating device capable of general -manipulated by any person without difficulty and without danger of getting the parts out of order; to provide a device of this character capable of turning on a pref;

erably horizontal axis through an entire circle, and to provide a construction in which in addition'to this movement the lamp can have a practically unlimited motion about an axis at right angles to the axis which has just been referred to so as to get a universal range of adjustment and'permit the lamp tobe turned to direct its rays in any desired direction.

The invention also involves the adj ustability of the lamp about a third axis at right angles to one of the others, a system of electrical connect-ions which are readily con trolled from the handle by which the main adjusting movement is secured; and improvements in details of construction and combinations of parts as will appear herei 1 inafter.

Reference is to be had to the accompanying drawings in which Figure 1 is a side elevation of a part of anmodification; Fig. 6 is a sectional view on the line 6-6 of Fig. 5; and Fig. 7 is a view similar to Fig. 2 of another modification showing it in central longitudinal section The invention is shown as applied to the dash of an'automobile and that is the preferable way of mounting it.. For this purpose the dash is provided with a support 8 mounted thereon and extending upwardly therefrom. This support is provided with a horizontal end 9 constituting a pivot for the lamp carrying frame 10. This frame is provided with a socket for receiving the pivot 9 and with a screw 11 entering a circumferential slot 12 in the end of the pivot. At the end the frame is slotted at 13 and a collar 14: is secured by a set screw or in any desired way to clamp the frame to the support. The parts are lubricated by a wick or the like saturated with oil and held in a slot in the frame by a plate 16.

On the central part of the frame is mounted a hollow handle 18 by which the frame is adapted to be turned on the pivot 9. This handle is provided at the end with a handhold 19 which is fixed on a rod 20 passing through the hollow handle and through the frame. On its front end it is provided with a miter gear 21 meshing with a miter gear 22 fixed on the bottom of a member 23 which is pivoted by means of a screw 24 or the like to turn on an axis perpendicular to the pivot 9 and also to the handle. In the normal position-of the parts this axis is vertical. On this the member 23 turns when the hand-hold 19 is turned on its axis as will be obvious. This member 23 Sup ports the lamp frame 25 and the latter is adjustable thereon about a horizontal axis, and can be secured in adjusted positions by means of a screw 26.

Thelamp is shown with an ordinary casing 27 and reflector 28, but it will be understood that any desired kind of lamp and fittings can be employed. An electric lamp is shown provided with electrical connections 29; one terminal of which is connected with-one of two wires 30 that extend along the handle. These two wires are designed to be electrically connected and disconnected by a pair of buttons 31 operating in a well known manner, so that the operator when manipulating the hand-hold 19 can control the current in a very simple way, I

It will be seen that by turning the handle about the horizontal axis 9, the whole frame with the lampcan be turned from the position shown in the drawings to a pos tion at the bottom in which the lamp faces rearwardly and in fact itcan be turned clear around 360 degrees if desired. Thus, the range of the lamp in this way is unlimited. It will be seen also that on account of the gear construction used for turning the lamp.

on the axis which is normally vertical the range of the lamp about this axis is also unlimited. -In this way by having these two unlimited adjustments the lamp can be turned to any desired position so as to throw its rays .in any desired direction. When turned to any position about these axes the lamp will remain in position Without tightening any fastening devices. I

The adjustment of the lamp about the axis of the screw 26'is intended to be of a more permanent nature, thus, the lamp is so set that when the handle is in the most convenient position for the operator the lamp will be throwing its rays directly forward either horizontally or at such slight inclination as may be desired. 1

In Figs. 5 and 6 a form is shown in which the frame 12 is of a different construction, and the rod 20 terminates Within the frame and has a bearing at the end thereof. In this case the gears 21 and. 22 are inclosed within the frame. The gear 22 is mounted on a shaft 23 to which is fixed the lamp frame proper 25. In this case the sam range of adjustments is possible.

In Fig. 7 is shown a form in which the frame or casing 12 is mounted in the same or any equivalent way, and the rod 20 is connected with a shaft 23 by means of aknuckle joint 35 or the like. This accomplishes the same results as far as the two unlimited adjustments are concerned.

It will be seen that by the constructions shownand any modifications thereof within the scope of this invention, a very simple arrangement is provided for securing an unlimited range for the lamp and yet it is of such a character that no complicated manipulation is required, and there are no parts that are likely to get out of order, or that are cumbersome or ungainly in appearance. At the same time the manipulating handle is located in a convenient position.

Although I have illustrated and described only three forms'of the invention, I am aware of the fact that it can be carried out in many other forms, and with modifications in many of the other details without departingfrom the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited in these respects, but

said pivot, said frame having a handle there- I I on and movable therewith for manipulating it, a lamp mounted on and movable with said frame, and means for turning said lamp on the frame about an .axis transverse to the axis of the pivot.

3. In a device of the character described, the combination of a support having a horizontal pivot, a lamp carrying frame mounted to turn about said pivot, said frame having a handle projecting therefrom a'ndmovable therewith for operating it, and means connected with and'opera'ted by the handle for turning the'lamp on an axis transverse to the handle.

4. In a device of the character described, the combination of a frame, a lamp carried thereby and rotatable thereon, a handle extending from the frame, a hand-hold on the end of the handlerotatable thereon, a rod connected with said hand-hold extending through the handle, a bevel gear on the rod, and a bevel gear connected with the lamp meshing with the first named bevel gear,

whereby the rotation of the hand-hold will.

mounted to turn, said frame having a handle thereon for turning it on an axis transon an axis transverse to the handle through.

an unlimited range, said lamp being adjustable through an are about a th1rd axis transverse to the handle and in a plane parallel to the first named axis.

6. In a device of the character described, the combination of a frame adapted to turn about a horizontal axis, a lamp mounted thereon and adapted to turn on the frame on an axis transverse to said horizontal axis and also adjustable about a third axis transverse to the last namedaxis.

7, In a'device of the character described, the combination of a frame adapted to turn, a handle projecting from the frame foropcrating it, a rod extending through the handle, a hand-hold on the handle fixed to the rod, a lamp on the frame, means connected with the rod for turning the lam on an axis transverse to the axis on w ich the frame turns When the hand-hold is turned on the handle, and electrical connections extending through said handle to the handhold for controlling the operation of the lamp.

- 8. In a device of" the character described,

- the combination of asupport having a pivot,

fa lamp carrying frame mounted to .turn about said pivot, said frame having a handle projecting therefrom and movable therewith (for operating it, and means connected itnesses.
