WOODWORK-SHAPER TABLE.

Application filed May 16, 1925. Serial No. 30,772.

This invention relates to an improved wood working shaper, and it has more particular reference to an attachment which serves to eliminate vibratory efiects and collar impressions caused by the present revolving collar of the conventional. shaping machine.

.ln order to attain eflicient results, it is thought that the rotary spindle of the shaping machine should be able to obtain not less than seventy five hundred revolutions per minute. The greater the rate of speed of the cutter, the more accurate and smooth the cut is, even where it is necessary to outagainst the grain of the wood. lhe practicability of high speed shaping machines, which are in great demand, is lessened by the presence of the usual hi h speed collar, tending to produce undue friction against the work, and thus making the use of the machine unduly expensive.

The present invention has been devised with a view toward eliminating the revolving collar and substituting arelatively stationary or dead collar, the improved collar being adjustable to vary the distance between the wort: and the axis of the cutter spindle.

The improved collar is accompanied by additional accessories, cooperating with the work, to maintain it firmly upon the surface of the table and to aid in holding it in contact with the rotating cutter.

These and other advantages and features of the invention will become apparent from the following description and drawings.

In the accompanying drawings, forming a part of this application, and in which like i'uunerals are employed to designate like parts throughout the several views:

Figure 1 is a top plan view of a portion of a shaping table, showing a pair of cutter spindles, together with the improved collar and other attachments.

Figure 2 is an enlarged side elevation of the details of the improved structure.

Figure 3 is a section, on an enlarged scale, taken approximately upon the plane of the line 33 of Figure 2, looking in the direction of the arrow.

In Figure 1 I have shown the invention duplicated, this being the usual. arrange ment on the conventional wood working shaper. Inasmuch as the details are in both instances the same, the description will appear in the singular. To this end, and by directing attention to Figure 2, it will be observed that the reference character 1 designates the fiat table of the shaper, which is provided with an opening to permit upis a perspective of the clamping ward passage of the spindle 2. As is well known, the cutters 2 are mounted upon the spindle for rotation therewith. In the show ing, I have indicated a retaining disc 3. As before indicated, it is customary to utilize a revolving collar in conjunction with this spindle. In accordance with the present in vention, however, the revolving collar is eliminated entirely, and the improved collar i is substituted, said collar 1 to engage the work 3* as shown in Figure 2. From Figure 6, it will be noted that the collar is preferably in the form of a relatively high band of thin metal. there being a block-like portion 5 formed integral therewith and this block being provided on its under side with a transverse rib 6 and acorrespondingly disposed channel 7. It is also provided with appropriate apertures 8 for the passage of fastenings. The improved collar is maintained in place, through the medium of a novel mounting. Considering Figure 2, it will be seen that the mounting comprises a base 9, fastened upon the top of the table 1, and embodying a vertical standard 10, provided in one side with a dove-tailed groove. A. supporting bar 11 is associated with this standard, the same having a'lrey 12, formed on one side and fitted into the groove in the standard. From Figure 4, it will be noted that the bar is provided at its bottom with an angular extension 13, having an upstand ing transverse rib 14, at its free outer end, and a channel 15 between the ends of its thick and thin portion. Adjacent the channel, it is provided with a socket 16 of rectangular cross section. Obviously, the block like portion of the collar 4 is connected to the extension 13, the rib 6 extending into the channel 15 and the rib 14 extending into the channel 7.

With the parts in the position shown in Figures 1 and 2, the stationary collar 4 surrounds the spindle 2 in concentric and relatively stationary relation and is disposed immediately above the cutter 2*.

The ring is designated by the reference character 17, the same being in the form of a horizontally flattened band, having a portion thereof formed into an arch 18. Fastened to this arch is an arm 19, having an enlarged head 20, formed with a square socket 21, slidably fitted on a correspondingly shaped post 22. it should be noted that this postis removably seated in the aforesaid socket 16. The ring 1? is preferably of a resilient nature and constitutes a clamp, for holding the work firmly down against the surface of the table, Fig. 2. The ring 17 is, of course, of a greater diameter than the collar 4.

To add further to the efficiency of the structure, I provide a starting bar, 23, having a slotted end 2 1, adjustably connected with the base 9. The free end portion of this bar is curved, as indicated in dotted lines at 25, and a slotted retaining bracket 26 is employed and fastened upon the base, to maintain the bar in various adjusted positions. In the majority of instances, a wood working shaper is primarily employed for shaping moldings and the like, and it is obvious that it is worked across the surface of the table in the usual way and brought to bear against the collar in the customary manner to permit it to be acted on by the cutters on the revolving spindle. Instead of encountering the revolving collar, however, which makes impressions and resists the movements, it is permitted to bear against the stationary or dead collar, which eliminates the said impressions and permits the work to be more easily handled. With the assistance of the starting bar 23 an operator can start cutting molding on end of material even if the cut is started against the grain, and this without ditliculty. The operation is also aided by properly positioning the resilient clamping ring 17 down upon the work to hold it sufficiently firm upon the surface of the table. This ring may be adjusted through the medium of the carrier arm 19 and the post- 22 upon Which it is slidably mounted. Undoubtedly, persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the same, after considering the description, in connection with the drawin Therefore a more lengthy description is thought unnecessary.

lVhile the preferred embodiment of the invention has been shown and described, it. is to be understood that minor changes coming within the held of invention claimed may be resorted to, if desired.

I claim:

1. In combination, a table, a rotatable soindle on said table, cutting means on said spindle, and a collar surrounding the spindle in concentric relation and fa tened to said table to render itrelatively stationary with respect to the revolving spindle, and a work clamping ring adjustably connected with the table and arranged about the spindle and stationary collar.

2. In combination, a table, a rotatable spindle extending above said table, cutting means on said spindle. a collar surrounding the spindle in spaced relation thereto and fastened to said table to render it relatively stationary with respect to the spindle and cutting means, and a starting bar adjustably connected with the table.

3.1n combination, a table, a rotatable spindle extending above said table, cutting means on said spindle, a collar surrounding and spaced from the spindle and fastened to said table to render it relatively stationary with respect to the spindle and cuttingmeans, a work clamping ring connected with the table in an adjustable manner and disposed about the spindle and collar, and a starting bar adjustably connected with the table.

4. In a structure of the class described, a base, a standard rising from said base, a bar vertically adjustable upon said standard, an extension at the bottom of said bar, a collar provided with means adjustably connecting it with said extension, raid extension being formed with a socket, a post removably seated in said socket, an arm provided with a head slidable upon said post, and a ring surrounding said collar, said arm being fastened to said ring.

In testimony whereof I affix my signature.
