SHAPER FOR WOODWORKING-MAGHINES.

Specification of Letters Patent.

Patented Feb. 3, 1914.

Original application filed April 24, 1912, Serial No. 692,884. Divided and this application filed October 22, 1912. Serial No. 727,203.

To all whom it may concern:

Be it known that I, GEORGE A. TURNER, of Kane, State of Pennsylvania, have invented certain new and useful Improvements in Shapers for l/Voodworking-Machines; 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.

My invention relates to an improvement in wood shapers, and particularly to means for mounting a pattern follower whereby the cutters may be adjusted with relation to the work, and is a division of application Serial Number 692,884, filed by me April 24th, 1912.

My invention consists in a wood shaper journaled to a vertically adjustable block, and a guide or pattern follower adjustably mounted on said block and embracing the spindle of the shaper.

My invention further consists in the parts and combination of parts and in the details of construction as will be more fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view partly in section and partly in elevation of a portion of a work holding table having a pattern guide, and the shaper wit-h my improvement applied thereto. Fig. 2 is a View in front elevation showing the shaper head mounted on its swinging carrier, and

Fig. 3 is a plan view showing the spring for holding the shaper to its work.

These shapers or cutters are employed in connection with a rotary table 1 carrying one or more clamps 2 for holding the work, and each clamp or the table adjacent each clamp, is provided with a pattern guide 3 against which the anti-friction guide or pattern follower 4 moves. This follower, one for each shaper, is in the form of a ring L-shape in cross-section, with the flange 5 projecting inwardly, and embracing an upwardly projecting flange 6 on the bracket 7 the upper face of the flange 5, and outer face of flange 6 are shaped to form an end less raceway for the anti-friction balls 8, which latter are retained in place by the flanged bushing 9 which latter has threads engaging internal threads on the flange 6 of bracket 7.

I would have it understood, that, while I have shown my preferred form of mounting the follower on the bracket 7, I do not limit. myself to such details, as my invention is broadly to a follower carried by a bracket adjustably mounted on the adjustable slide block carrying the shaper.

The bracket 7 and bushing 9 have alined openings for the passage of the spindle of the shaper l0, the head 11 of which is located above the bracket. This shaper which may be of any preferred construction, is mounted in bearings 12 on the block 13, which is mounted for vertical adjustment in the swinging frame 14, the latter being grooved to receive the block 13, and provided if desired with an adjustable guiding strip 14, by means of which lost motion due to wear may be compensated for. A lug 15 projects from each slide block through a slot in ts swinging frame 14, and is pro vided with a threaded hole for the engage-- ment of the threaded end of rod 16, which latter is supported by and journaled in the rearwardly projecting bearing 17 on swinging frame 14. By turning the rod 16. with a wrench or other tool, the block 13 carrying the shaper may be adjusted lengthwise the swinging frame so as to bring the cutters carried by the shaper head into proper position with relation to the work.

Mounted in the upper end of each sliding block 13 is a screw 18 which passes through a hole in the lip 19 of bracket 7, with its threads in engagement with threads formed in the block 18. The bracket 7 is secured to one end of the sliding-block by the screw 20, which passes through an elongated slot in the bracket and engages a threaded hole in the end of the block. By loosening up screw 20, the bracket will be free to be moved by screw 18, in or out and thus adjust the follower 4 to proper position with rela- Each swinging frame 14 has two arms 21,

each of which is provided at its free end with a bearing 23, the upper one of which receives the pintle 24: and the lower one the pintle 25. The upper pintle is screwed into a bracket 26 on fixed frame 27, and is provided with a plain end to engage hearing 23, while the lower pintle is simply a headed pin mounted in a bracket or fixed frame 27. I prefer however to interpose bronze collars 28 with hardened balls 29 between them, intermediate the lower bearing 23 and its support, so as to provide for an easy swinging movement. Projecting rearwardly from the rear face of each swinging frame 14 is an arm 30 which is connected at its free end to one end of a spring 31, the opposite end of which is secured to the frame 27. These springs yieldingly hold the pattern follower t in contact with the outer edge of the pattern guide, and the cutter 32 in contact with the side edge of the blank 33, so that the cutters reproduce on the blank, the curve of the outer edge of the pattern guide.

The shaper spindle is provided with a pulley 34 around which the belt passes, the latter being held taut by any approved form of belt tightener.

lVith the construction as shown, the shaper with the pattern follower thereon, may be adjusted vertically and the pattern follower may be adjusted at right angles to the former adjustment so as to bring the cutters into proper engagement with the blank.

It is evident that slight changes might be resorted to-in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact construction and arrangement of parts shown and described, but,

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is:

1. In a wood shaper, the combination of a swinging frame, a block mounted for vertical adjustment in said frame, a shaper journaled in bearings on said block, and a pattern follower secured to the block and hori- Zontally adjustable thereon, the said follower being ring shaped and encircling the shaper spindle below the shaper.

2. In a wood shaper the combination of a swinging frame, a block mounted for vertical adjustment in said frame, a shaper journaled in bearings on said block, a bracket secured to the upper end of said block and adjustable horizontally thereon, and a ring shaped pattern follower mounted on ball bearings carried by said bracket, the said. follower encircling the shaper spindle below the shaper.

In testimony whereof, I have signed. this specification in the presence of two subscribing witnesses.

GEORGE A. TURNER.
