' 8 Claims.
The present invention relates to what is believed to be a new and structurally novel hand actuated and controlled machine for use in the electric lamp and bulb industry, wherein said machine isexpressly constructed to operate substantially automatically and mechanically to expeditiousiy construct assembly.
In this particular line of endeavor much precision and care. requiring. painstaking eiforts, must be resorted to in perfectly constructing the filament mount preparatory to enveloping or incorporating it in the bulb or globe. In the more expensive type bulbs a now somewhat primitive-method is followed which consists in making that portion of the mount known as the multiple wire retention button. It is unnecessary, it is believed, to provide here a resume of. this class of handiwork other than to say'that 'after the head or button is fashioned, the filament supporting wires are attached thereto, by hand, involving a one-by-one tedious and unreliable procedure. Confronted with the unnecessary time consuming and laborious handmethods now in use, I have, after much experimentation and due de-' liberation, developed a machine which will do mechanically, which was heretofore done by hand,
such machine being so designed as to do a better job in an almost uncanny uniform and standardizedmanner. 1 i 1 While the cardinal point of-the conception is the preferred machinery adapted for this express purpose, novelty is thought to reside also in the methodical or procedural ways and means of clenching or bending thewires into requisite exactitude in so far as companionate relationship is concerned.
0 Manifestly, my chief aim is, therefore, to pro mote progress in'this industrial line of endeavorthrough the adoption and useof an expedient and practicable mechanical machine or device, which, through the aid of a skilled attendan t, will per- 45 mit the button and wire assembly, as a unit, to be perfected with requisite certainty andspeed.
Other features and. advantages of the invena so-called button and wire casting the button, imbedding the wires, and J Figure 2 is a horinontal section on the plane of the line 2-2 of Figure 1.

Referring now to the drawings, and conveniently to Figure 1, it will be observed that the invention is a bench-type contrivance such as may be conveniently referred to as a machine. The bench is indicated by the numeral It. The
. stand or base unit is unitarily identified by the numeral l1 and comprises an appropriate base plate ll having perpendicular uprights I! with or form the head of the swivel fixtures .20 supported on the upper ends.
thereof." The-burner heads, of the gas blower head includes a manifold 22 with a battery of nozzles 23,. Rising centrally between the uprights i9 is an integral adapter member-.24 having a 4 designates a magazine-type chuck.
Advantage is taken of this arrangement by placing on the pin a sleeve 38 having bayonet slot and pin means 39 and4ll. At the bottom of the sleeve is a knurled collar 4| which functions as a wire bending matrix, as hereinafter disclosed (see Figure 11).
I next call attention to the numeral 42 which This is adapted to be chargedwiththe customary long and short filament supporting wires -43-and 44,
respectively. structurally, this part 42 comprises a disk or plate 45 centrally apertured and having a .series of properly spaced radial grooves 46 constituting slideways for the projectlble and retractible plungers 41. The plungers are made in long and short series, as shown diagrammatically inFigure 6, to accommodate correspond-r ingly proportioned wires 48 and 44. Then, too,-
each plunger has at its outer end a head 48 provided with a seat 49 to receive the correspondin end of the wire to be inserted in the button. Furthermore, the numeral 56 designates an actuating pin extending down through adjacent slots in the plate, as seen in Figures 3 and 11.,
The marginal portion of the wire charged plate is surrounded by an annular rim including a relatively rotatable ring 5| having riveted thereto a flanged'annulus 52. These two features 5| and 52 provide the turnable or rotatable rim, this being provided with an operating handle 53. The part 5| has cam. slots 54 therein, as seen in Figure 4, to accommodate the headed end of the pin 56. Hence, by rotating the rim in relation to the plate 45, the cam slots and coacting pins coordinate to project the plungers 41 inwardly and to carry the wires in the same direction for anchorage.
It is to be observed that the central portion of the plate 45 is provided with a square collar 55 fitting non-rotatably on the correspondingly shaped upper end of a reciprocatory cylinder 56 slidably mounted in the adapter mounting 24.
Furthermore, the upper, part 51 of this collar constitutes the relatively movable matrix to coact with the aforementioned relatively stationary matrix 4| to bend the wires 43 and 44.-
Attention is now called to the numeral 58,- this designating a reciprocatory tube. The upper end thereof is formed into a head, as at 59 (see Figures 14 and '15), this head forming a rela-- 6|, to properly space the inner ends of the wires- 43 and 44 as they are projected, by the aforevided with a lifting and lowering handle 66 ex- 5 tending out through the slots 25 and selectively engageable with the keeper notches 26.
- In order to simplify the assembly, there is slidably mounted in theinner cylinder or tube 58 the hand twirled holding and spinning spindle 10 64 for the glass rod 65. As before indicated, this glass-rod is commonly referred to in the trade as a button. It is slipped down into a socket in the upper end of the spindle 64 and is held therein by spring retention clips 65', as shown in Figure 15 8. It is alternately rotatable and slidable in the inner cylinder 58 and provided at its bottom with an operating knob 66. .As soon in Figure 3, the lower knob-equipped portion of the spindle is properly shouldered as indicated at 61 to limit 20 the downward drop of said spindle when it is released by hand.
In practice it is to'be understood that the chuck-type wire holding magazine 42 is properly charged with the customary group of seven wires, 25,
this being done by a companion attendant sothat it is in readiness for use by the operator of the machine. It follows, therefore, that when the magazine 42 has been properly loaded with the wires, it is placed on top of the reciprocatory 30 cylinder or jack 56.
The operation of the machine is as follows: The first thing to do is 'to place one of the standard out reeds or glass rods 65 in the holding spindle 64. This is accomplished as seen in a.
Figure 8 and the machine is now set to begin operations. In the first place, the operator catches hold of the knob 66 and pushes the spindle upwardly in relation to the relatively stationary surrounding sleeve or tube 68. This 4Q heated to the desired degree, the knob 66 is re- 50 leased and the holder 64 dropped down to the position seen in Figure 3. While the glass is in this molten or substantially plastic state, the next operation is to grasp the handle 68, lift up 'on the tube or sleeve 58 to bring the two heads 66 and 55 59 together to mash or compress the glass therebetween. This casts or forms the head 66 on the glass rod. Then the handle 66 is properly lowered to bring the headed glass rod down into the chuck again so that the inner ends of the 43 and 44 can be projected into the glass head or button 68. This means thatall that is necessary here is to grasp the handle 52 of the chuck and to turn it, thus projecting the wires through the slits 6| into the glass to properly space and anchor the wires. When this is accomplished, the handle 66 is returned to its original position so that the wires register again with the slots 46 in the chuck plate 45.
After the wires have been allowed to set sumciently long to become satisfactorily anchored in the button, they must then be bent into the perpendicular L-shaped form seen in Figure 11.
This is accomplished by lifting the complete jack, including the chuck head, to bring the 75.
Moreover, 45
I matrices ll and 51 into play. Before this is effected, howeveathe sleeve 38 of the matrix II is lowered and locked in place so that the cup end ll is now down over the molding head 36, as shown'ln Figure 11. The matrix ll thus becomes a form around which the wires are bent to L- shape form. As the movable matrix 51 comes up and around the matrix 4|, this brings the parts into telescoping relationship, and obviously bends impinge thereon. This oscillation about the axis a .the button G8 this being accomplished by squeezthe wires. Now thejack, including the chuck or magazine, is lowered, and the wire-equipped unit is extracted, as is obvious.
It has been found expedient and practicable to include in the upper end of the cylinder an insert 69 having a cushioning springto allow the head 59 to recede into the same during the wire bending operation, as is brought out in Figure 11.
The method phase of the discovery is evident from the diagrammatic group illustration appearing in Figure 12 of the drawings. First, we begin with the glass rod 65, which is a stock product. This is inserted in the hand spindle which is lifted up and-turned back and forth with the fingers while the flames from the burners oi the rod quickly preheats the upper end of the glass to a state to permit it to be flattened into ing or clamping the heated and of the-glass rod between the clamping'or molding heads 59 and 36, respectively (see Figure 14). Then the wires are inserted in the manner described and as shown in said Figure 12. Finally, they are bent mechanically by the liftable jack" means. l'I'hese steps are brought out to advan'tagein Figure 12 of the drawings.
It is evident that a machine of the type herein shown and described is calculated to fulfill a long felt need in this particular line of endeavor. It is characterized by relative simplicity, taking into consideration the progressive stepsto be carried into eiiect. Its operation is sufiiciently simple to Justify unqualified endorsement by the trade in general.
Itisthought that the description taken in con-' nection with the drawings will enable a clear understanding of the invention to be had. There- 'fore, a more lengthy description is thought unnecessary. v I
While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.
