Application August 3, 1944, Serial No. 547,929

1 Claim. (Cl. 29499) This invention relates to a radio tube extractor. A primary object of this invention is the provision of a device whereby radio tubes or the like may be removed from their sockets without the necessity of touching the same with the fingers.

An additional object is the provision of a device whereby a radio tube may be removed from a socket located in such position as to be difilcult of access by the fingers or hand.

/ A still further object is the provision of a de- Tvic'jebwhereby a hot radio tube may be removed without touching the same thus obviating the possibility of burning the fingers.

Additional objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully pointed out hereinafter and disclosed in the accompanying drawings, wherein there is shown a preferred embodiment of this inventive concept.

In the drawings Figure 1 is a perspective view of one element comprising a part of the instant invention.

Figure 2 is a perspective view of another element of the device.

Figure 3 is a side elevatlonal view of the elemeht of Figure 2.

Figure 4 is a top plan view of the elements of Figure 1. v

Figure 5 is a bottom plan view of the elements shown in Figures 2 and 3, and

Figures 6, 7, and 8 are side sectional views of the assembled device in three different positions of adjustment.

Like reference numerals refer to like parts throughout the several views of the drawings.

Having reference now to the drawings, Figure 1 discloses a sleeve it of sheet metal or the like, provided with a looped handle II. A member generally indicated at I! (see Figures 2, 3 and 5) comprised of a pair of tapered portions II and a resilient handle ll securing portions I: together at their upper extremities, is adapted to be positioned. within sleeve l0. Portions II take the form of conic sections, curved to conform to the radius of curvature of sleeve i0 and are provided at their lowerextremities with inwardly turned portions I! forming flanges, when the device is assembled a suitable link it (see Figures 6, 7 and 8) is provided surrounding handles ii and ll to securethesameinalignmentandtolimitthe movement of member l2 with respect to sleeve III.

The operation of the device should now be readily understandable. When it is desired to remove a radio tube, member i2 is slid to its lower.- most position with respect to sleeve I0 whereby a substantial amount of portions I3 extend outwardly below the sleeve, and the resiliency of handle i4 tends to bias such portions outwardly with respect thereto so that the same may be readily slipped downwardly over a radio tube 11. Sleeve Ill is then moved downwardly by means of handle I i to assume the position shown in Figure 7 whereupon the lower edge of sleeve Ill forces members I3 inwardly until flanges 15 are positioned under the edge of the base ill of radio tube ll. Drawing handle l4 upwardly toward handle I I, to the position shown in Figure 8, now lifts the tube ll from its associated socket and the same may be removed from the radio and released from the device by returning the parts to the position shown in Figure 6.

From the foregoing it will now be seen that there is herein provided a radio tube extractor which is sturdy and durable in construction, re-

liable and efllcient in operation, and relatively simple and inexpensive to manufacture, and which accomplishes all the objects of this invention and others including many advantages of great practical utility.

As many embodiments may be made of this inventive concept and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.

I claim:

In a device of the character described, in combination, a sleeve, a handle on said sleeve, a pair of tapered members positioned for movement within said sleeve, a resilient handle member connecting said tapered members at their upper extremities and biasing their lower extremities outwardly with respect to said sleeve, a flange at the lower extremity of each of said members adapted to engage the base of a radio tube, and means securing said handles together to hold the same in alignment and limit the movement of said sleeve and said tapered portion with respect to each other.
