FLOATING-HEATHER HOLDER.

Application filed November 5, 1915.

To all whom it may concern:

Be it known that 1, ROBERT RAILTON, a citizen of the United States, and a resident of Valley Falls, in the county of Providence and State of Rhode Island, have invented a new and Improved Floating-Reamer Holder, of which the following is a full, clear, and exact description.

My invention relates to an improved means whereby to support a reamer in a manner that it may freely float with a parallel movement in any direction to properly aline with the hole to be reamed.

With my improved means the socket memherfor receiving the reamer floats in a direction transverse to the spindle having guided movement on the face of the spindle and the socket has means therein which permits the floating of the reamer in said socket in a direction t 'ansverse to the floating movement of the socket member so that a parallel floating movement of the reamer is positively insured in any direction.

The invention will be more particularly explained in the specific description following.

Reference is to be had to the accompanying drawings forming part of this specification in which similar reference characters indicate corresponding parts in all the views.

Figure l is a side elevation of a reamer holder embodying my invention; Fig. 2 is a sectional plan view on the line 22, Fig. 1; Fig. is a, transverse vertical section on the line 3 3, Fig. 1; and Fig. 4: is a perspective view of the floating socket member for receiving a reamer.

la carrying out my invention in practice, a spindle 10 is provided, the shank of which is adapted to be suitably secured in. a turret. The face 11 of the spindle has a depression 12 which receives the base 13 of a socket member 14-. At the front of the face 11 of the spindle 1O guide plates 15 are secured at the top and bottom overlapping the base 13 of the socket member 1 1-, the inner edges of the said plates 15 being received in grooves 16 formed in opposite sides of the socket member 14:.

By the described arrangement the socket is guidingly held on the -face of the spindle and is free to float thereon in a direction transverse to the axis of the spindle. The floating movement is limited in both direc- Specificationof Letters Patent.

tions by set screws 18, or equivalent means, provided. on the face 11 of the spindle at opposite sides.

In order to obtain the universal parallel floating support for the reamer 20, the shank thereof is received in an elliptical socket 19, the major axis of which is at right angles to the direction of movement of the floating socket member 1a. A pin 21 extends through registering pin holes 22 in opposite sides of the socket member 14; and extends through the shank of the reamer 20 at the major axis of the socket 19.

' Universal floating movement is thus provided for the reamer and the correct alining of the reamer with the hole to be reamed can be effected with absolute accuracy and with great facility. Moreover, the universal floating movement is provided for by means involving the minimum weight.

In the case of heavy reamers, off one inch or over in diameter, I provide a spring of su'llicient tension to overcome the weight of the reamer after it has entered the hole to be reamed. For this purpose a screw plug 23 is provided on the socket member 14 at the underside and is formed with a pocket 2% which receives a spring 25 on the upper end of which the shank of the reamer 2O rests. In practice, the tension of the spring is such that it will tend to maintain the reamer slightly above the center of the socket 19 so that a slight pressure on the reamer will serve to depress the same to correctly aline with the hole to be reamed.

It is to be understood that they term spindle as applied to the element 10 is used because it is the usual shop term employed to designate this part and that it is not intended to limit the form of the device to the spindle shape shown since any other equivalent means to engage in a hole or socket in a turret or the like may be employed.

The provision of the oval socket prevents sidewise movement of the reamer in the socket, it being understood that the minor axis of the oval socket is such as to snugly receive the reamer, there being, in practice, but one-thousandth of an inch difference between the diameters of the socket at the minor axis and the reamer. Thus, the improved socket insures a unidirectional play of the reamer, the advantage of which is that when the reamer is entering the hole to be reamed, the taper or lead of the reamer Will bring the slide in exact alinement With the hole.

Having thus described my invention I claim as new, and desire to secure by Letters Patent:

1. A holder for reamers including a spindle and a floating socket member having guided movement on the spindle in a direction transverse to the axis of the spindle and provided in the socket thereof with means to hold a reamer to float in said socket in a direction transverse to the direction of movement of the socket member on the spindle.

2. A holder for reamers including a spindle, a socket member having floating guided movement on the spindle in a direction transverse to the axis of the spindle, and a pin ranging across the socket of said member transverse to the direction of movement of the socket member on the spindle, the said pin affording guided movement for a reamer lengthwise of said pin.

3. A. holder for reamers including a spindle, a socket member having floating guided parallel movement on the spindle in a direction transverse to the axis of the spindle, the socket of said member being elliptical and having its major axis transverse to the direction of movement of the socket member on the spindle, there being means on the socket member to secure the shank of a reamer and permit floating movement of said reamer in the direction of the major axis of the socket.

a. A reamer holder including a spindle, guide means on the face of the spindle, a floating socket member retained by said guide means to float in a direction transverse to the axis of the spindle, and adjustable stops on the spindle limiting the floating movement of the socket member in both directions, said socket member having in the socket thereof means to support a reamer to float in a direction transverse to the move ment of the said socket member on the spindle.

In a reamer holder, a socket member, means to support said socket member to float in a direction transverse to its axis, and means to secure a reamer in the socket of said member to float in a direction transverse to the movement of the said socket member.

6. A reamer holder and a floating socket member thereon, said member having an elliptical socket and adapted to receive a reamer, the major axis of said socket being at right angles to the floating movement of the said member.

7. In a reamer holder, a floating socket member having an elliptical socket adapted to receive a reamer, the major axis of the socket being at right angles to the floating movement of the said member, and a guide pin extending across the socket at the major axis thereof and adapted to extend through the transverse aperture of a reamer to'guidingly retain the reamer for floating movement relatively to said socket member in the direction of said axis.

8. In a reamer holder, a socket member adapted to receive a reamer and permit a parallel transverse movement of the reamer in the socket, and spring supported by the socket and extending transversely into the bore thereof in position to form a lateral rest for a reamer. v

9. In a reamer holder, a socket, a socket member adapted to receive a reamer, means to secure a reamer in the socket and permit a vertical parallel movement of the reamer in the socket, and a spring in the bottom of the socket member and extending into the socket thereof to bear transversely against a reamer.

10. In a reamer holder, a socket member adapted to receive a reamer, a screw plug in said reamer at the underside forming a pocket, and a spring in said pocket extending into the socket of said member to bear against a reamer.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
