THE BEE-KEEPERS' REVIEW 



It can, however, be belted to an old corn 

 sheller, or any other crank machine, or 

 pulley, which will give sufficient speed 

 for practical boring. 



The shaft is a small piece of gas pipe 

 with a wood split-pulley fastened at one 

 end, and a small gimlet at the other, 

 fastened securely by a wooden plug fitted 

 into the end of the gas pipe. This plug is 

 halved and gouged out to take in the 

 gimlet shank, and the whole is then 

 driven tightly into the end of the gas 

 pipe or shaft. 



The boxings are pieces of hardwood 

 with holes to fit the shaft. Babbit box- 

 ings would be better. 



The platform which this rests upon is a 

 one by six inch board, Z}i feet long. 

 The sliding table is a one by six inch 

 board, one foot long, with strips nailed on 

 each side, and extending below the edges 

 of the board where it fits over the plat- 

 form, and slides back and forth to and 

 from the gimlet. 



A slide, fastened crosswise of this 

 sliding table, holds the end-bars, and can 

 be moved backwards or forwards to 

 bore holes anywhere from one end to 

 the other of the end bar. 



A spring-trigger is fastened back of 

 this, with one end reaching over the bar- 

 holder, which has notches cut to receive 

 the end of the trigger, and hold the bars 

 to the exact place for boring. 



Seven end-bars can be bored at once, 

 which takes up the whole length of the 

 gimlet; and a forward and backward 

 movem.ent of the sliding table is all the 

 time it takes to do it. 



The trigger-spring is made from a 

 corset steel and the trigger is controlled 

 by the hand which slides the table. A 

 firm grasp of the hand-hold and over 

 the trigger hold the end-bars in place 

 while boring the hole, when the trigger 

 is instantly released, and springs up half 

 an inch, releasing the bar-holder, which 

 is moved to the next notch, the trigger 

 gripped again, the hole bored, and so on, 

 all taking less time than it takes to tell it.
