THOROUGHFA'RE TAP HOLDER;
" APPLIGATION EILED APR.10, 1907.
QIIIC HANS HEYNAU, OF DOTZHEIM, NEAR WIESBADEN, GERMANY. i
' THOROUGHFARE TAP-HOLDER.
Application filed Api-il 190'7. Serial No. 367333.
To all whom it may concern: I
Be it known that I, HANs HEYNAU, engineer, a subject of the King of Saxony,.residing at Dotzheim, near Wiesbaden, in the. Kingdom of Prussia and German Empire, have invented new and useful Improvements in Thoroughfare Tap-Holders, 'of which the" following is a specification- My invention relates to anin'iproved tap holder, designed more particularly for use in tapping thoroughfare holes in wholesale work.
The invention is illustrated in the accompanying drawing, in which Figure 1 is an elevation, partly in section, of the new holder. 2 is an elevation, the holder being viewed at right angles to Fig. 1. Fig. .3 is an underside view of the holder. Fig.4 isan end view. Fig. fiisasection'of a socket to be hereinafter referred to.
Fig. 6 is a cross-section through the socket on the line A B of Fig. 5, and Fig. 7 shows a small steel Wire spring. I The top part of the holder a is conical and may be fitted into an ordinary drillin 2 machine. The lower portionis recessed an receives a sliding headb, caused to partake of the rotary motion of the holder by means of a feather c, and. having an internal square ada ted to-receive the ta hen the tap has cut tiirou h the hole, the descending head I) is forced own uponthe work and is conse uently pressed back into the recess in the ho der. Into the bottom of the recess there isscrewed a in d, which when the head I) has. been pushedbaok against Specification of Letters Patent.
the recess bottom, knocks the tap out of the 1 Patented March 3, 1908.
the machine. On the holder (1 being run up,
the head I) is retilrned to its initial position by. a spring f, coiled round the pin 11, the one end bearing against the bottom of the recess and the other end against a disk g resting upon the square in the head I). The tap can now be reinserted in the head.
In order. to adapt the holder for ta s of holder o so that it drops upon the table of' different sizes, sockets such as shown in igs. 4 and 5 may be inserted in the head I).-
.These sockets have an external square hdapted to fit the head b and an.internal square to receive the tap in use. The entire holder. is made of magnet steel and strongly magnetized, so that the taps and sockets may be effectiwelyprevented from dropping out. If desired, small springs .9 made of steel wire may be inserted in the head and socket as shown in Figs. 1, 5 and 6 to serve the same puWose asm 'netization. r hat I do 0 aim as my invention and desire to secure byfLetters- Patent, is f A tap holderipomprising a shank having a recess, a pin {projecting thereinto and a spring actuated tap receiving head having a" bore slidable in" the recess and splined tothe shank.
