SPECIFICATION forming part of Letters 1: atent No. 788,941, dated May 2, 1905.
Application filed April 18,1903. Serial No. 153,263-
To all whovn it may concern.-
Be it known that I, AZARIAH Y. PEARL, a citizen of the United States, residing at West Lebanon, in the county of York and State of Maine, have invented a new and useful Improvement in Angers, of which the following isafull, clear, and exactdescription, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to angers for boring square and rectangular holes; and the same consists, essentially, in improved means and devices for removing the chips, and consists in features and details which will be more fully explained and pointed out in the description of the drawings.
This invention consists in improvements upon the device shown and described in Letters Patent Nos. 505,844, October 3, 1893, 565,500, August 11, 1896. and 909,575, June 28, 1898.
The object of this invention is to provide a tubular conveyer for the rapid removal of chips from the work and consists of a hollow tube connected to the upper end of the guideblock, through which the driving-shank passes centrally, and a spiral conveyer secured to said driving-shank and turning within the aforesaid tube, the said tube having an orifice near its upper end for the discharge of the chips.
A further object of this invention is to provide an improved form of cutter-propeller, the same having an increased clearance between the blades to facilitate an easy discharge of the chips, together with other improvements which will appear in the following specification as follows, to wit:
Figure 1 is a side View of the auger, showing the side cutter-face, also the orifice in the tube for the discharge of chips. Fig. 2 is a vertical section on line 2 2 of Fig. 1. Fig. 3 is a detail view of the propeller and drivingshank, showing the spiral conveyer attached thereto. Fig. 4 is a detail section on line 44 of Fig.2,showing the enlarged clearance-space in the guide-block.
In this invention the principal features and mode of operation are the same as shown and described in my previous patents above referred to, and consists, essentially, of a central shank 1, to the lower end of which is secured a suitable bit 2. The said bit 2 and the shank 1 have a bearing in the guide-block 3, which is square in cross-section, each side of which is equal to the diameter of the bit 2, and cutter-wheels 4, secured on two opposite sides of the guide-block 3 by screws 5. These cutter-wheels 4 are separated from the guideblock 3 by thin metal washers 6. To the upper end of the guide-block 3 there is secured a tube 7, whose diameter is slightly less than the diameter of the guide-block 3. This tube 7 may be of any desired length, and near its upper end is a lateral orifice 8 for the discharge of chips. At the upper end of the tube 7 there is inserted a cup-shaped block 9, and a ring 10, of a diameter slightly less than the bore of the cup-shaped block 9, surrounds the shank 1 and is pinned thereto by a pin 11, passing through the ring 10 and shank 1. Suitable holes 12 are provided through the side of the tube 1 and cup-shaped block 9 for the insertion and removal of said pin 11. Above the ring 10 there is a second ring 13, surrounding the shank 1, and screws 14, securing tube 7, the cup-shaped block 9, and the ring 13 together, thereby forming a thrustcollar, both upward and downward, for the ring 10 an d the shank 1. The ring 13 has a conical orifice 15 at its upper end, and the shank 1 has a lateral orifice 16 communicating with the bottom thereof, so that oil poured in at 15 will enter through the orifice 16 and be discharged through orifice 17 for lubricating the cutterwheels 4 in a manner substantially as described in my previous patents. Above the ring 13 there is placed a split ferrule 18 for taking the set-screw in the spindle of the drill or other press that operates this auger. The lower end of the shank 1 terminates in the propeller 19, provided with blades 20,'which engage the teeth of the cutter-wheel 4. This propeller 19 differs from that shown in my previous patents by having the blades 20 grow thinner as they extend upward and also taper in toward the shank 1, thereby giving an increased clearance for the chips as they travel upward. (See Fig. 3.) The guide-block 3 instead of having an upper orifice for the discharge of chips of cylindrical form and a diameter substantially the same as the diameter of the propeller is provided with an orifice which flares out in the direction of the cutter-wheel 4, as indicatedin Fig. 4: at 21, forming a sort of inverted funnel, and this very materially assists in a free discharge upward of the chips and prevents clogging. After the chips have passed the blades 20 of the propeller 19 they are met by a spiral conveyer 22, which lifts them up the tube 7 until they come opposite the orifice 8, from which they are discharged.
The functions and operation of this tool being in all respects similar to those described in my previous patent, a description of those features will not be here repeated.
' I claim as my invention 1. An auger havingahollow shank, cuttingtools operatively connected thereto to form an angular bore,a non-rotatable guide-block having a tubular extension above, within which is a spiral conveyer secured to and operated by the said hollow shank, a thrust-collar secured to said shank above the spiral conveyer and thrust-bearing secured to the tubular extension from the guide-block, and an oil-orifice in the said hollow shank above said thrustbearing, substantially as described.
