GEORGE S. OLOW, OF COLUMBUS, OHIO.

MACHINE FOR TE NOI\ IING AND BORING IMPLEMENT-HANDLES.

SPECIFICATION forming part of Letters Patent No. '7' 55,359, dated March 22, 1904;.

Application filed October 14, 1903.

To all whobt it may concern.-

Be it known that I, GEORGE S. OLow, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Machines for Tenoning and Boring Implement-Handles; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object generally of this invention is to' provide an improved machine for simultaneously tenoning and boring an implement-handle, whereby time and labor are saved.

Special objects, among others, are to provide an automatically-operative gage or stop and an automatically-operative chuck or holder for the handle while being tenoned and bored, so that the only manual operations required are the insertion into and removal from the chuck of the sticks constituting the handles, and means whereby the tenoning and boringtool-is made self-clearing.

The invention consists in the combinations of parts hereinafter described and claimed.

In the accompanying drawings, illustrating one embodiment of the invention, Figure 1 is an elevation taken at the left-hand side of the machine as faced by the attendant. Fig. 2 is a top plan view. Fig. 8 is a section on the line so a", Fig. 2. Fig. 4 is a front view of the chuck and operating devices with the front covering-plate removed. Fig. '5 is a diametrical section of the chuck. Fig. 6 is a detail of the tenoning device or shaper. Fig. 7 is a section of the same on-line 3/ Fig. 6. Fig. 8 is a detail of the stop or gage and its operating devices.

1 designates a bed that is supported upon legs 1. The bed supports a slide or carriage 2, having separated bearing-containing parts 2 rising therefrom that in turn support a rotatable mandrel or shaft 3, having a belt-pulley 3 between the bearingcontaining parts 2 for the application of the necessary power to turn the mandrel. This mandrel 3 has an enlarged forward end 3*, into which is screwed the threaded shank of the tool-holder 4:. The toolholder L contains an appropriate knife or Serial No. 177,050. (No model.)

knives 4 for tenoning or shaping the outer side or ferrule-receiving portion of the stick and a bit 4 located in the axis of the toolholder. The bit 4" is preferably removable from the tool-holder and is locked in place after the holder has been screwed up into place by means of a set-screw 3, passed through the end 3 and ahole in the threaded shank of the tool-holder and having its end pinching the bit. The set-screw also prevents the toolholder from turning in its seat. The rear end of the mandrel turns against a brass bearing 3, seated in a box 3" to take the thrust of the mandrel when working, said brass bearing being supported by one or more adjustable setscrews 3 to compensate for wear.

Journaled on an appropriate bracket 5 at the rear end of the bed is a shaft 5, standing at right angles to the mandrel 3. The shaft 5 carries at its left-hand end opposite the rear end of the mandrel 3 a groove-cam 5 the groove of which engages a stud 23, secured to and projecting from the rear end of the toolcarriage 2. The groove of the cam is of such form, substantially as shown, that it moves the tool-carriage forward and backward twice in one revolution of the cam. The backward movement between the two forward movementsis for the purpose of allowing the tool to clear itself of shavings and chips.

Journaled in brackets 6 at the right-hand side of the bed is a shaft 6, standing parallel to the mandrel 3. This shaft contains a belt-pulley 6", and power is transmitted from this shaft to the shaft 5 by means of a miter-gear 6 on the rear end of the shaft 6, meshing with a similar gear 5" on the shaft 5.

Secured to the front end of the bed. is the chuck for holding the stick constituting the handle when it is tenoned and bored. This chuck comprises a frame-plate '7, several radially-arranged sliding shanks 7 I having clamping-jaws 7 and pins 7 and adisk 7 having eccentric slots 7 engaging the pins 7 so that when the disk 7 is turned the jaws 7 are moved inward or outward, according to the direction in which the disk is turned. At-

tached to the disk 7 and extending laterally therefrom and above the shaft 6 is a lever-arm 7 having a downward projection 7 prefer- IOQ ably provided with an antifrictionroller 7 The opening between the clamping-jaws 7 is 7 arm 7 and separate the clamping-jaws? to permit a handle that is to be tenoned and bored to be inserted and the removal of the handle after it has been so treated, and the lever-arm 7 can be weighted or provided with a spring 7 attached to a fixed part of the machine to hold the jaws closed on the handle to secure or chuck it tightly while being tenoned and bored.

The gage or stop for determining the distance the handle to be treated shall be inserted into the chuck consists of a lever 8, fulcrumed on small standards 8 adjustable and fixable on the bed 1, so that the inner end of the lever can stand across the path of the toolholder at the desired distance from the chuck.

The outer end of the lever 8, whichis pro-.'

vided with an antifriction-roller 8, extends over the shaft 6, which latter is provided with a cam 6 shaped to depress and hold the inner end of the lever out of the way when the tenoning and boring operation takes place and permit that end to rise. when it is to serve as a stop or gage, the lever being of sufficient weight at its outer end or weighted or provided with a spring for that purpose.

Inoperation the power-shaft 6 and mandrel are driven with a constant motion. The workman inserts the end of a stick that is to constitute the handle of the fork, rake, hoe, or other implement into the chuck,when the jaws thereof are separated, the gage limiting the extent to which the stick is insertible. The jaws of the chuck then close tightly on the stick, and the gage automatically moves down out of the way. After this the tenoning and boring tool moves up onto the end of the stick and shapes it externally for the usual ferrule and bores it internally for the shank of the implement; but by reason of the shape of the groove-cam 5 at the rear of the machine the cutting and boring tool makes two forward and two rearward movements, the first rearward movement being sufficient to permit the toolholder to clear itself of shavings and chips, and therefore to do clean perfect work. The rapid motion and flaring shape of the opening of the tool-holder effects this automatically through centrifugal force on the shavings and chips. Thus it will be observed that both the tenoning and boring of the handle are effected simultaneously and that all the operations except the mere insertion and removal of the handles from the chuck are performed automatically.

What I claim, and desire to secure by Letters Patent, is

1. In a machine for tenoning and boring implement-handles, the combination of-a tool for simultaneously tenoning and boring the handle-blank, a reciprocating carriage for supporting thetool, means forrotating the tool, and means for automatically gaging and chucking or holding the handle-blank while the ten oning and boring tool is moved onto it.
