MACHINE FOR SECURING FlLAMENT-HOLDERS INTO GLOBES 0F INCANDESCENT LAMPS.

SPECIFICATION forming part of Letters Patent No. 537,493, dated April 16, 1895.

Application filed May 17,1894. Serial No. 511,626. (No model.)

To aZZ whom it may concern:

Be it known that we, ARNOLD J. SPILLER, a subject of the Queen of Great Britain, and JOHN R. MASSEY, a citizen of the United States, residents of Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Machines for Securing Filament-Holders into the Globes of Incandescent Lamps, of which the following is a specification, the principle of the invention being herein explained and the best mode in which we have contemplatedapplying that principle, so as to distinguish it from other inventions.

The annexed drawings and the following description set forth in detail, one mechanical form embodying the invention; such detail construction being but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings-FigureIrepresents an elevation of our improved machine for securing the filament holders into the globes of incandescent lamps; Fig. II, an enlarged elevation of one of the devices for holding the globe and filament holder during the time of afliixing the latter to the former; Fig. III, a vertical sectional detail view of the shaft and sleeve upon which the filament holder and the globe are held, and of the means for sliding the sleeve upon the shaft; Figs. IV, V, and VI, sectional views, respectively illustrating the relative positions of the filament holder and the globe, before the heat is applied to the same, while the heat is applied, and after the filament holder has been secured into the neck of the globe and the waste portion of the globe has been pulled off from the portion of the globe which remains, and Fig. VII, a plan View of the weight for removing the Waste portion of the neck of the globe.

A series of radiating arms, A, project from a hub, A, the lower end of which has clutch teeth, a which engage with corresponding clutch teeth, b, upon a sleeve, 13, which slides upon a hollow standard, C, having suitable base, C. A spring, D, serves to; force the clutch sleeve B upward, and alever,B, is pivotally connected to said sleeve,and has its fulcrum upon a bracket, 0*, which projects from the base C, of the standard. A connecting rod, 13*, is pivoted to the lever B, and is pivoted to a treadle, B by means of which the clutch sleeve may be depressed against the spring.

The number of teeth upon the hub and the clutch sleeve corresponds to the number of arms A, so that each arm may stop .at the proper place after the clutch sleeve has been depressed, the arms revolved, and the clutch sleeve again released. Each arm has a vertical frame, A in which a shaft, E is journaled. Said shaft has a friction disk, E, at its lower end, which may engage,when brought to register with the same,\vith a friction disk, F, upon a horizontal shaft, E, which receives its motion from any suitable motive power. l

A forked frame, .G, has a collar, G, within which a sleeve, H, which fits upon the vertical shaft E, may vertically slide. The collar of the forked frame and the shaft E are connected by means of a key, g, and the sleeve H has longitudinal slots, it, through which the key passes, and which permits the sleeve to slide upon the shaft and within the collar, while the shaft,-sleeve and forked frame may rotate together.

A circumferentially grooved collar, H, is

' secured upon the lower end of the sleeve H,

and a ring, H fits into the groove of said collar and is pivotally connected to a hand lever, H which is fulcrumed upon a bracket, a, projectingfrom the frame upon the outer end of the arm A. The free arm of the hand lever bears against a bolt, a, which slides in a vertical bore, 01. in the frameupon the outer end of the arm A, and has a spring, a surrounding it and bearing against a shoulder uponthe bolt and against a shoulder in the bore,

so that said spring may raise the free end of {the lever after the latter has been depressed.

The upper end of the sleeve H is flared, to form a flange, h, upon which the flaring end of the filament holder may rest, and against the sharp cutting edge of which the contracted neck of the globe may bear. A spindle, E

is removably secured in the upper end of the shaft E, and projects beyond the end of the sleeve H,-having a collar, 6, against which the flaring end of the filament holder may rest,

said funnel, with its neck resting against the flaring flange of the vertically movable sleeve. A suitable weight, J, preferably in the shape of a spring clamp, is fitted upon the waste portion of the neck of the globe, so as to pull said portion downward, when the glass has been sufficiently heated and softened at the joint between the flaring end of the filament holder and the globe, and said joint has been welded, the sleeve being then depressed so as to allow the weight to draw the waste portion of the neck downward.

Suitable blow pipes, K, are supported at oppcsite points, in such manner that the point at which the welding of the globe and filament holder is to be accomplished, may be exactly at the meeting point of the jets issuing from the blow pipes. In the drawings, one blow pipe isillustrated as supported from the hollow standard 0, and the other blow pipe is illustrated as supported upon a standard, L, and the meeting point of the jets from said blow pipes is so gaged, that the welding tinctly claim as our inventionpoint of each globe upon each of the radiating arms A, which form the turn table of the machine, may be successively brought to register with the meeting point of the jets of the blow pipes.

In. practice, the filament holder is placed upon the upper end of the spindle, theglobe is placed over the filament holder, with its contracted neck bearing against the flange of the vertically sliding sleeve, the weight is clamped in position upon the lower end of the neck, and the turn table is rotated and stopped by means of the clutch, with the welding point of the filament holder and globe in the meeting point of the jets of the blow pipes; while the friction disk upon the lower end of the shaft, at the same time, engages the friction disk upon the power shaft. The shaft, globe-supporting frame, and sleeve will thus be revolved,exposing all sides of the neck of the globe to the jets of the blow-pipes, exactly at the point where the welding of the filament holder and globe is totake place. The relative positions of the filament holder, globe, filament holder su-pport,.and sup-portfor the neck of the globe, are illustrated in Fig.

- 1V. As the jets of the blow pipes exert their influence upon theneck of the'revolvingglobe, the walls of the neck will soften and adhereto the edge of the flaring end of the filament support, as illustrated in Fig. V. When the glass at the welding point has been suffi- -ciently softened, the hand lever 11 is depressed, and the weight and theneck support will tear oif the waste portion of the neck of the globe. The welding point of the globe and filament holder may be yet exposed to the action of the blow pipe jets for a short space of time, so as to thoroughly weld the joint between the parts, and so as to even the edges at the joint. IVhile one globe is being acted upon by the blow pipe jets, other globes may be placed in position upon the supports at other points of the turn table, and the finished globes may be removed from their supports, and the waste portions of the necks may be broken off.

The neck support h, is preferably of copper or other material which will not adhere to glass when exposed to heat, sufficient to soften glass, and the sharp edge of the support will materially assist in severing the surplus neck. portion from the globe, when the glass is softened at a circumferential line registering with the edge, as the glass cannot adhere to the edge and the surplus portion will, consequently, fall away by its gravity, aided by the weight and by the downward motion imparted to the neck support.

Other modes of applying the principle of our invention maybe employed for the mode herein explained. Change may therefore be made as regards the mechanism thus disclosed, provided the principles of construction set forth respectively in the following claims are employed.
