LATHE ATTACHMENT.
APPLICATION FILED SEPT. II. 1916- L22'7A86, Patented May 22, 1917.

SAMUEL'NEWMAN AND HENRY It. BOTHWELL, 0F CINCINNATI, OHIO, ASSIGNORS TO SAID NEWMAN.
LATHE ATTACHMENT.
Application filed September 11, 1916. Serial No. 119,347.
To all whom it may concern Be it known that we, SAMUEL NEWMAN and HENRY R. BOTHWELL, both residing at Cincinnati, Hamilton county, State of Ohio, have invented a certain new and useful Improvement in Lathe Attachments, of which the following is a clear, full, and exact description, attention being called to the drawing which accompanies this application and forms a part thereof.
This invention concerns an attachment whereby a lathe of the usual type may be used like a turret lathe.
It consists of the particular construction of the attachment as described hereinafter .and as pointed out in the claims.
This construction is also illustrated in the accompanying drawing in which:
Figure 1. shows our attachment in sideview, part of a lathe being also shown to indicate its position thereon.
Fig. 2. shows at enlarged scale a longitudinal section taken in a vertical plane through the center of the attachment.
Fig. 3. is a rear-view of the attachment as shown in Fig. 2.. Y
The attachment is supported on the tailstock of the lathe, it being detachably connected to the sleeve therein which carries the tail-stock center.
In the drawing this sleeve is indicated by numeral 6, the center being removed therefrom when the attachment is to be placed in position.
The attachment consists of the tool-holder A which is in form of a hub, and of a bracket B upon which it is mounted for rotation and whereby it is connected in place.
Bracket B consists of a shank 7 provided with a socket and adapted to be slipped upon sleeve 6. The shank is longitudinally split on one side and is provided with a clamping screw 8 whereby after being placed on the sleeve it may be firmly held thereto.
At its free end this shank is enlarged and forms a flat circular seat 9 for hub A. This seat is at an angle to the longitudinal axis of the shank and from its center there projects a boss 11 which forms a pivotal support for hub A about which the latter may be rotated for adjustment. This boss forms an integral part of bracket B. I
The hub in its circumferential side is pro vided with a number of sockets 12 adapted to receive the tools to be used for doing the work.
We show five of such sockets providing a capacity for using five different tools or similar tools of different sizes to perform various kinds of work such as drilling, tapping, reaming, counterboring, etc.
In the drawing we have shown two tools in position, a drill and a reamer. These tools are seated in bushings 13 and held in their sockets by means of set screws 14.
The position of tool-holder A on bracket B and the arrangement of the sockets in the tool-holder is such that with the given possibilities of adjustment all of these sockets, any one at the time, may be longitudinally alined with the live spindle of the lathe by rotarily moving the tool-holder about boss 11.
Or expressed in other words these sockets may be so adjusted that their longitudinal axes will be in alinement with the lathecenters, provided they were in their places.
For the purpose of finding this proper position there is an indexing device which consists of a pin 15, fitted for longitudinal movement into a housing 16 provided for it in an extension 17 which forms part of the bracket.
A spring 18 serves for the purpose of giving the pin a normal tendency to move toward the tool-holder and into one of a number of openings 19 provided in the side thereof. There is such an opening for each tool socket and they are properly spaced and located so that when the end of pin 15 occupies any one of these openings and thus holds the tool-holder, a tool socket is also in the proper alined position as described above to permit use of the tool car ried therein.
Pin 15 is so positioned as to be diametrically opposite the socket which carries the tool to be used at the time.
The outer end of pin 15 is hingedly connected to a lever 21, between the ends thereof which lever is pivotally connected at one end between a pair of links 22 whereby it is supported on the bracket or on extension 17 thereof.
whereby pin 15 may be withdrawn to per- Patented May 22, 1191? I mit adjustment of the tool-holder to a different position when another tool is to be used. As will be observed this indexing device remains stationary and alwaysjmay be found in the same position, which position is most conveniently located above the rear tail-stock.
A locking screw 24 is provided seated in boss 11. It has a clamping flange 25 whereby when being caused to bear on the toolholder, the same is securely clamped in position against its seat after indexed and independent of pin 15.
A handle 26 is provided for manipulation of this locking-screw.
Having described our invention we claim as new:
1. In a tool-holding lathe-attachment, the combination of a bracket comprising a split clamping shank having laterally projecting clamping flanges, a clamping screw seated in these flanges, the outer end of this shank presenting a flat surface of circular outline and inclined to the axis of the shank, a boss projecting integrally from the center of this surface and at right angles thereto and provided with a screw threaded socket in its outer end, a tool-holder having tool sockets and fitted to the inclined surface mentioned which forms a seat for it and to which it is held for rotary adjustment by the boss on said surface, an indexing device provided on the bracket and serving to position the tool holder in any particular adjustment, a locking screw seated in the socket in the boss having a locking flange adapted to engage the tool-holder and a handle projecting outwardly from this flange and serving for manipulation to cause said flange to clamp the tool-holder to its seat to hold it in its adjusted position.
In a tool-holding attachment for lathes, the combination of a bracket which comprises a clamping shank adapted for attachment to the tail-stock of a lathe, the outer end of this shank presenting a flat surface inclined to its axis and having an integral boss projecting from it, a tool-holder substantially hub-shaped mounted on this boss and fitted to said inclined surface which forms a seat for it, the circular side of this tool-holder presenting two substantially conical surfaces meeting at their largest diameters and of which one surface is adjacent to the seat of the tool-holder and provided with spaced index openings, the other surface having correspondingly spaced toolsockets, an extension projecting upwardly from the clamping shank containing a housing and so positioned as to be opposite that surface of the tool-holder which contains the index openings, a pin fitted to this housing, a spring sleeved onto it and imparting a normal tendency to impel it into one of the openings mentioned when in juxtaposition for any particular adjustment, means to clamp the tool holder to its seat when so adjusted, a lever linked to said upward extension on the clamping shank and to which the indexing pin is connected and a handle projecting from this lever so as to extend rearwardly above the tail-stock to manipulate the 1ndex1ng pm.
In testimony whereof we hereunto a'h'ix our signatures.
SAMUEL NEWMAN. HENRY R. BOTHWELL.
