ELECTRIC BEEHlVE-HEATER.

SPECIFICATION forming part of Letters Patent No. 702,833, dated June 17, 1902.

Application filed March 18, 1902. Serial No. 98,857. (No model.)

To all whom it may concern:

Be it known that I, HENRY VOGELER, a citizen of the United States, residing in the town of Newcastle, county of Placer, and State of California, have invented a new and useful Electric Beehive-Heater, of which the following is a specification.

My invention relates to improvements in beehive-heaters wherein electricity is used to generate heat to Warm and dry the inside of a beehive and preserve colonies of bees during very cold weather. I attain these objects by the construction, arrangement, and combination of parts shown in accompanying drawing, which represents a sectional view of my heating attachment.

(1 indicates a portion of the front of a beehive, b a tube attached thereto, and c a heater in the form of an incandescent electric lamp. The said tube b is inserted and held in a hole bored in the hive-front a, the location being preferably the lower portion of tho broodchamber at one side of the bee-entrance. The tube projects from the front a and is inclined downward to adapt it to carry 0ft moisture and also to facilitate the inward flow of air heated by the lamp 0. The cavity of the tube 1) is shown enlarged near its outer end to provide due space for the lamp 0, which lies upon its side, the conductors passing through the mouth or entrance 7?. of the tube, as shown. The lamp being of greater diameter than the passage at either end it cannot be detached by accident. Supports e are provided on the floor of the tube to hold the lamp 0 in such position that air may pass freely in contact with its under side. An inspection-opening is provided at f in the upper side of the tube directly over the lamp 0 and closed by glass disks to prevent escape of heated air. The tube 1) is shown divided longitudinally at g, and thus into two parts, which are held together by compression oftheir inner ends in the hole bored in the hive a; butIpropose to provide for insertion and removal of the lamp 0 in any other manner that judgment may suggest. It is apparent that'the electric current being turned on the heat radiated from the lamp-filament will heat the surrounding air, which will tend to fiowupward, and thus into the hives, as indicated by arrows, where it warms the interior. I propose to vary the degree of heat by the-size or power of the lamp 0, the latter being adapted to be readily removed to allow substitution of another.

When the heating attachment is not required for use, the tube 12 is removed and the hole in the hive a is plugged.

What I claim is 1. The combination, with a beehive, of an exterior, detachable, air-heating attachment comprising an open-end tube which is held in a bore in the hive and projects therefrom, and a heating medium, contained within the tube, and means for heating the air passing through the tube into the hive as described.

2. The combination with a beehive of an air-heating attachment comprising an openend tube held in an opening in the hive-Wall, an incandescent electric lamp, supported within said tube, and having conductors extended out of the same, as shown and described.

3. The combination with a beehive of an air-heating attachment consisting of an openend tube which is held in an opening in the hive-wall, and inclined downward therefrom,- and a lamp contained and duly supported in the tube, as shown and described.

4. The air-heating attachment for a beehive, consisting of an open-end tube and an incandescent electric lamp secured within the tube, as shown and described.

5. The combination with a beehive of an air-heating attachment comprising an openend tube made in two longitudinal parts adapted to be easily separated, and a lamp contained in an enlargement of the passage in said tube and having greater diameter than name to this specification in the presence of air-heating attachment comprising a lamp two subscribing witnesses. I

and a tube which is open at each end and provided with an inspection-opening at the point where the lamp is located, said opening being HENRY VOGELER' 5 closed to passage of air by a transparent me- Witnesses:
