EARL WJNEAL, OF NEW YORK, N. Y., ASSIGNOR 'TO WESTERN ELECTRIC COMPANY, INCORPORATED, 015 NEW YORK, N. Y., A CORPORATION OF NEW YORK.
HEATER. I
To all whom it may concern:
Be it known that I, EARL W. NEAL, a citizen of the United States, residing at New York, in the countyof Bronx, State of New York, have invented certain new anduseful Improvements in Heaters, of. which the f0llowingis a full, clear, concise, and exact de scription.
This invention relates to heaters and more particularly to a heaterespecially adapted for use in the manufacture of'vacuum tubes. One type of vacuumtube has a base comprising a metal shell, which is attached to the neck of. the tube by meansof a cement comprising alcohol as a solvent. After the cement has been placed in position between the shell and the tube and has set, it is desirable that the alcohol solvent be thoroughly dried out.
It is the object of this inventionto provide a heater for the above and similar purposes which is simple in construction and efficient in operation.
It is a further object of this invention'to provide a heater in which'the bases of a plurality of tubes may be dried simultaneously and. inserted or removed individually without disturbing the condition of the other tubes in the oven.
With these objects in View, a plate-like electric heating element is employed, and the bases of vacuum tubes are held in position to receive the heat from the heating element by means of tubular sockets carried by a plate of brass or other heat conducting material which lies adjacent the heating face of the heating element. The sockets are preferably of the same or similar material as the plate, and are provided with a latch or equivalent means for holding the tubes in position. The oven, as a whole, is con veniently mounted for manipulation of the tubes with the heating element in horizontal position and the sockets depending downwardly therefrom.
The invention will be more fully understood from the following detailed description and claims taken in connection with the accompanying drawings, in which Fig. 1 shows in side elevation a heater embodying the invention, Fig. 2 is a bottom lan view of Fig. 1 with the supporting standards in section, and Fig. 3 is a detail sectional view on an enlarged scale on line 33 of Fig.1.
Referring to the drawings by reference Specification of Letters Patent. Patented Jan. 31,1922. Application filed March 28, '1919. Serial No. 285,939. l L
numerals, standards .10, which may be of metal covered with" asbestos, asatl11,support a horizontal plate 12 of'brassor other suitable heat conductingmaterial. Secured in circular openings 13 (Fig. 3) inplate 12 are tubular socket members 14. There is one row of sockets adjacent each longitudinal edge of the plate. Mounted above the plate 12 is an electric heating member 15, which may be, as shown, a standard heat unit, taking a current of about eleven amperes, at 110 volts. The body of heating member 15 is composed of insulating material 16"having. embedded therein, near the lower surface, conductors 17 having a relativel high resistance to electric currents. Suitab e c'onnections therefrom to a source of heating current are provided, as indicated at 18.
A vacuum tube 19 is shown with its'base inserted in one of the sockets 14. This tube is one of the type above referred to, having-a shell 20 attached to the neck 21 of the tube by means of cement 22. The pin 23 is one member of a bayonet joint (the other memberof whichis not shown), employed for securing the tube in its position of use. Each socket 14 is provided with aslot 24 to receive the pin-23, and the pin '23 is engaged by a latch 25 for the purpose of holding the tube in position. These latches are mounted for independent pivotal movement on a rod 26 adjacent each row of sockets. The latches 25 are each provided with a weighted operating lever 27, which normally acts to hold the latch in looking position.
While the preferred embodiment of the invention has been shown and described, it is to be understood that the invention is not limited to the exact structure and arrangement shown, but comprises the use of equivalents within the scope of the appended claims.

10. Ina heating apparatus, a heater, a metallic plate adjacent said heater, a series of article-holding sockets mounted M on said plate, a rod mounted adjacent said sockets, and latches pivoted on said rod for holding articles in said sockets respectively.
11; In a heating apparatus, aheater, a
socket connected thereto, and means for holding an article in said socket, said means comprising a pivoted latch having aeighted handle. I
12. In a heating apparatus, a heater, a socket of heat ccnducting material connected thereto adapted to receivea vacuum tube, and yielding means itor retaining said vacuum tube in said socket.
13. In combination, a base member having a socket member projecting therefrom, said socket being adapted to receive a vacuum tube having contact terminals, and means for yieldably holding saidterininals against said base member. a
'14. In comb'nation, a socket of heat con ducting material adapted to receive the base of a vacuum tube and means for applying heat to said socket. v 15. In combination, a socket adapted to receive a laterally projectingpin, and means for holding said vacuum tube in said socket, said means comprising a pivoted latch having a.
