ANGELO SANTILLI, OF NEW YORK, N. Y., ASSIGNOR TO GASPARE MORETTO, OF NEW YORK, N. Y.

TOOL FOR HANDLING ELECTRIC GLOBE-LAMPS.

To-aZZ whom it may concern;

Be it known that I, ANGELO SANTILLI, a

d subject of the King of Italy, and a resident York, have invented'a new and Improved.

Tool for Handling Electric Globe-Lamps, of which thefollowing is a full, clear, and exact description.

Among the principal objects for which the present invention is designed are: to provide a simple, convenient, and easily.operated means for gripping and holding the globe of an electric lamp .at the end of a rod, whereby globes may be inserted in, or removed from elevated sockets; and to provide gripping means for the'globe, certain in action and delicate in its operation.

ing drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both 4O located in the ceiling of roomsor in the views, and in which Figure 1 is a longitudinal section of a tool constructed and arranged in accordance with the present invention; and. Fig. 2 is a side view of the tool, showing a modified form thereof.

As seen in the accompanying drawings, the stem of the tool is constructed from hollow tubing, of continuous and suitable length, the ends whereof are annularly grooved to form gripping surfaces for the internally grooved necks 8 and 9 of the cup 10 and bulb 11, respectively. The tube for the stem 7 may be constructed of any suitable material. As stated, the length of the tube varies to suit the particular use for which it is employed. These tools are generally used for removing the globe A from sockets cornices adjacent thereto. As the ceiling is high or low, the length of the stem 7 is accordingly varied. 1

The cup 10, as seen in the drawings, is provided with a soft and pliable lip 12.

The lip 12 is sufi'iciently frail to readily spread when the cup is lifted and pushed against the bulging or outer end of the globe A. To give sufiicient rigidity to the on 10, it is provided with areinforcing ri ge 13, and below the said ridge 13, the walls of the cup are-thickened, so that the "cuphas the twofold quality of sulficient rigidity in the body portion thereof to Specification of Letters Patent.

maintain its shape, while the lip 12 is sufficiently flexible to yield to the outward pressure of the globe-when being inserted therein, and to be supersensitive to the operation of the partial vacuum formed within the cup 10.

The rarefaction of the atmosphere inthe cup 10 is produced by means of the bulb 11. The walls of the bulb 11 are continuous.

'Through the stem 7, the interiors of the 5 cup 10 and of the bulb 11 are in open 'compresses the bulb 11, to eject the air there- 7 from. The air, in passing from the bulb 11, is expelled through the tube 7 and the I cup 10, and between the lip 12 thereof and Reference is to be had to the accompany.

the side of the'globe A. \Vhen, in turn, the

bulb, 11 is released, and the walls thereof are permitted to assume the rotund shape, the displacement of air draws upon the air in the stem 7 and cup 10, and rarefies to that extent the air in the said stem and cup.

The resultant effect is to produce a rare- 30 faction within the body of the cup, against which the pressure of the exterior atmosphere operates, to force the lip 12 firmly against the side of the globe A, to grip the same gently but firmly. The adhesive quals5 ity of the rubber of which the lip 12 is .composed permits the same. to-so grip the globe that when the stem 7 and cup 10 connected therewith are properly rotated, the

globe, thus gripped, is. screwed into, orunscrewed from the socket in which it is installed. If the operation be to remove the globe from the socket, "when this is accomplished and the globe has been lowered to the floor, table, or the hand of the operator,

serted by hand in the cup- 10; the air is .105

ejected from the bulb 11, stem 7 and cup 10 by pressing the said bulb, when the grip of the lip 12 on the glove A will be exerted as above described. After the globe has been raised to, and screwed into the socket pro- 110 The pressure of the air at vided therefor, the lip 12 is caused to release its grip by compressing the bulb 11 to restore the equilibrium of the air within and without the cup 10.

The modified form of the invention disclosed in Fig.2 consists in providing, at the lower end of the stem 7, a cylinder 14. Within the cylinder 14 is mounted a suitable piston 15, having a plunger rod 16 rigidly connected thereto. The rod 16 is extended beyond the end of the cylinder 14,

and is provided with a grip 17. The operation of the pump thus constructed is to extract the air from the stem and cup when the piston 15 is drawn outwardly. For this purpose, the piston 15 is furnished with a soft leather or rubber pad 18, the edges whereof wipe the sides of the cylinder 14, and when the piston is drawn outwardly, the edges of the said pad form sliding air-tight joints with the inner surface of the cylinder 14/ The piston 15 has sufficient clearance from the inner surface of the wall of the cylinder 14 to permit the passage of air therebetween. The forward movement of the piston and the pad 18 does not, therefore, compress the air within the stem 7 or cup 10. When, however, the piston 15 is drawn toward the outer end of the cylinder 14, the edge of the pad 18 is seated against the side of the cylinder 14, to close the passage between the piston and the said cylinder, to prevent the air passing inward into the stem 7 and cup 10. This subtraction of the air from the tool results in a compression of the lip 12 upon the globe A inserted within the cup 10, as above described.

Having thus described my invention, .1 claim as new and desire to secure by Letters Patent 1. A tool such as described, comprising an elongated tubular stem; a flexible cup 1,02e,2se

mounted at the end thereof, said cup shape'd to partly surround an electric globe, and

said cup having a thin resilient edge to expand when manually pressed upon said globe; and means for rarefying the air in said cup.

2. A tool such as described, comprising a suction cup shaped to receive an electric light globe, said cup provided with an expansible edge, the normal diameter of which is less than the greatest diameter of said globe, to extend over and rest upon said globe above the greatest diameter thereof; and means for rarefying the air in said cup.

3. A tool such as described, having a suction cup shaped to receive the enlarged end of an electric light globe, and to extend thereover above the line ofgreatest dimension of said globe; means formed on said cup to close the passage between said globe and said cup above saidline of greatest dimension; and means for rarefying the air in said cup.

.4. A tool such as described, having a suction cup shaped to receive the enlarged end of an electric light globe, and to extend thereover above the line of greatest dimension of said globe; means formed on sai cup to close the passage between said globe and said cup above said line of greatest dimension; and means for rarefying the air in said cup, said means embodying an air displacing member and a rigid tubular stem in open communication with the interior of' c said cup.
