Description
2.5%, 2 J. E. BYRNE v 6 TAFPING MACHINE Fatented Jilly 22, 1924.
JOHN E. BYRNE, or PLATTEVILLE, wrsconsriv. .5
' TAPIPING MACHINE. .4;
Application filed August 12, 1921; Serial No. 491,713.
T 0 all whom it may concern.
Be it known that I, JOHN E. BYRNE, a native-born citizen of the United States, residing at Platteville, in the county of Grant and State of Wisconsin, have invented certain new and useful Improvements in Tapping Machines, of which the following is a specification.
The invention relates to improvements in a tapping machine. It is a primary object of the invention to provide a tapping machine'for tapping horse shoes, although the machine is capable of other uses. The invention more specifically-embraces a tapping machine which is power driven, and wherein the tap may be rotated in either direction, and one wherein the horse shoe or like article is gradually advanced into contact with the tap to insure an expeditious tapping thereof.
In the accompanying drawings I have disclosed a specific embodiment of my invention, but obviously the construction may be materially changed without departing from the invention.
In the drawings Figure 1 represents a side elevation of the device; Figure 2 represents a top plan View; Figure 3 represents a section on line 3-3; and Figure 4 repre sents a section on line 4 -42 of Figure 1.
Referring now more particularly to the drawings, wherein like reference characters indicate corresponding parts, the numeral 1 designates the base of the machine which may be of any approved construction. The base is provided with guides 2 forming a continuation thereof, receiving a shoe support 3 having a seat 4 fashioned to ride within the grooves at the base of the machine. This shoe support, as will be clearly I appreciated, is moved forwardly during the operation of the machine for advancing a shoe in a position to be engaged by the tap or to disengage the tap. The shoe support 3 at its upper end is provided with a lever 5, the free end of which enters a slot 6 in a keeper 7, and which lever 5 supports a shoe 8 in a manner so as to permit a bore to be formed therein by the tap, the support 3 having an aperture 9 passing therethrough at a point where the shoe is lined up to engage the tap. The lever 5 is spaced from the shoe support 3 only a sufficient distance as to cause an interposed shoe to be frictionally engaged by the lever and firmly held in position.
ward or reverse direction, I dispose thereon A shoe is provided with the necessary apertures to receive anti-slipping. calks or to permit worn out calks to be removed from the shoe for the replacement of new'ones. 6
The tapping mechanism preferably comprises a rotary tap 10 received in a chuck 11, which chuck is fixedly attached to a shaft 12. Rotatably mounted upon this shaft isa belt pulley 13 for rotating the tap in one direction, and a belt pulley 14 also rotatably mounted on the shaft for rotating the same in an opposite direction. 'The shaft 12 is mounted in bearings 15 arranged at the outer end of the supports 16, and is of course free to revolve in said bearings. The pulleys 13 and 14 are driven by the usual belts, but unless coupledwith the shaft do not impart a rotary motion thereto. For the purpose of holding the pulleys 13 and 14 in position I employ shields 17 and 18 surrounding the shaft at a point near the bearings therefor.
To permit the shaft to be rotated in a fora clutch 20 having the clutch faces 21 and 22, which clutch is splined upon the shaft, and is adapted to be shifted so that the faces 21 and 22 may be engaged with the faces 23 and 24c of the pulleys 13 and 14. To operate this clutch a clutch lever 25 having a forked end seats within a groove intermediate the clutch, said lever being pivoted at the point 27 and having a handle portion 28, which is shifted over the segment 29 so that said handle can be moved from a neutral position into the slots 30 and 31 in the segment, which maintains the clutch in its desired position of adjustment.
Assuming that a shoe is to be tapped, the 9 same is placed in position upon the support 3 and the clutch lever shifted so that the clutch face 21 engages the clutch face 23 of the pulley 13. A suitable belt then rotates this pulley, a rotary motion being imparted to the shaft operation the tap 10, The shoe is moved into contact with this tap and is advanced progressively during the rotation of the tap until a hole is threaded therein. The clutch lever is then shifted so that the clutch faces 22 and 24 are engaged, while the clutch faces 21 and 23 are disengaged and the rotation of the pulley 14 then operates the tap shaft in a reverse direction, withdrawing the tap from the receiver.
then the clutch lever is moved to a neutral- When the machine is inoperative,
' position wherein the rotation of pulleys driving pulleys loosely mounted upon said shaft, detachable face clutch interposed between said pulleys and splined to the shaft, means for shifting the said clutch so as to engage either of the pulleys to rotate the shaft in a forward or reverse direction, said shifting means comprising a lever engaging the clutch, a handle therefor, a segment over which said handle travels, and means formed in the segment for locking the handle in adjusted positions.
In testimony whereof I aflix my signature.
