BEVERLY G. MOSS, OF WASHINGTON, NORTH CAROLINA.

LUMBER-MEASURER.

SPECIFICATION forming part of Letters Patent No. 666,904, dated January 29, 1901.

Application filed August 9, 1900. Serial No. 26,4:20. (No model.)

To all whom it may concern:

Be it known that I, BEVERLY G. Moss, a citizen of the United States, residing at Washington, in the county of Beaufort and State of North Carolina, have invented certain new and useful Improvements in Lumber-Measurers; and I do hereby declare the following to beafull, 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 improvements in lum ber-measurers; and it consists in the novel features hereinafter described, reference being had to the accompanying drawings,which illustrate one form in which I have contemplated embodying my invention, and said invention is fully disclosed in the following desoriplion and claims.

The objects of my invention are, first, to provide a device for measuring large quantities of lumber, either in linear or square feet, the width and thickness being known; secondly, to provide means in connection with the said device whereby the index-plates may be set back to zero, and, thirdly, to supply suitable means for supporting said device so that all thicknesses of lumber may pass thereunder without any further adjustment.

Referring to the drawings, Figure l represents a longitudinal section of a woodworking-machine,taken alongthelength of the bed. Fig. 2 is a section on line 2 2, Fig. 1. Fig. 3 is a section on line 3 3, Fig. 2; and Fig 4 represents enlarged views of the index-plates, showing the graduation thereon.

A represents a woodworking-machine, 0 which B B are the revolving cutters, O O and D D the feed-rollers, E a strip of lumber, and F my improved lumber-measurer, I) being the star-wheel thereof.

The casing F of my device is provided with two lugs F and F one at either end thereof, to which the mounting-spring G is secured. An opening in the lower part of this mountingspring permits a bolt G to pass therethrough and engage the screw-threaded aperture in the guide-plate H, which is secured to the bed I of the Woodworking-machine. This construction,it will be seen, serves as an'adjust-able support for the device, and thus will allow all thicknesses of lumber to pass under the measurer. Suitable openings 00, y, and z are vprovided in the front of said casing for the display of graduated index-plates, hereinafter described.

Projecting through a suitable bearing in one end of the casing F is an operating-shaft a, on the outer end of which is fixed the starwheel I). On the other end of this shaft is a worm a, gearing with a worm-wheel c, mounted on a shaft 0 supported in a suitable bearing at one end and telescoping into a loose sleeve 61 at the other. A pin 0 is rigidly secured in the shaft 0 and enters the longitudinal slot d in the sleeve d. The outer end of the sleeve above referred to extends out beyond the side of the casing and is provided with a knob K. The innerend of this sleeve has an operating spur gear-wheel d fixed thereon and is kept in engagement with the indexplate gearing, hereinafter described,by means of a spiral spring 0 which surrounds the shaft 0 and bears against the worm-Wheel c and the said operating gear-wheel d It is very plain that the slot 0' will permit the operating mechanism to be thrown out and will thus allow the device to be set back to zero.

The index plate gearing consists of the large gear-wheels e g i and the small pinions f h, mounted on the shafts c g, which carry the first two gear-Wheels e g. These gearwheels are arranged to mesh with the small pinion on the shaft of the preceding gearwheel, the first gearwheel 6 meshing with the operating gear-wheel (P. The rat-i0 of these gearwheels to their pinions and operating mechanism is as ten to one. One of the shafts which carry the gear-wheels, the middle one 9 shown in the drawings, is provided with a thumb-piece for revolving the said shaft and setting back the index-plates when the operating mechanism is thrown out, which has been hereinbefore described.

The index-plates M N 0, before referred to, are secured to the front of the gear-wheels c, g, and i. Three of these gear-wheels and index-plates are shown in the drawings, but the n umber may be increased without departing from the spirit of my invention. Upon the face of each of these index-plates are concentric circles, which are divided into ten equal parts by radial lines, the points of intersection of these radial lines and the first circle from the edge representing the numberof linear feet in certain lengths of boards, the second representingthe number of square feet of lumber in the boards of a certain Width, and the otheroircles representing the number of square feet in boards of still other widths.

What I claim,and desire to secure by Letters Patent, is-- 1. The combination with a woodworkingmachine provided with a table and feed mechanism, of a casing, openings in the front of said casing, index-plates carried by suitable gear-wheels within said casing, means for operating said index-plates, means for setting back said index-plates, a supporting-spring connected to both ends of said casing and means for securing said spring to said table, substantially as described.

2. The combination with a Woodworkingmachine provided with a table and feed mechanism, of a casing, openings in the front of said casing, index-plates carried by suitable gear-wheels within said casing, a thumb-piece mounted on the produced end of the shaft of one of said gear-wheels, a star-wheel in the path of the moving lumber, a Worm on the'shaft of said star- Wheel, a Worm -wheel gearing with said'worm, a loose sleeve fitting over the shaft of said WOl'iIl-WhGBl, means for limiting the movement of said sleeve, a gearwheel mounted on said sleeve adapted to normally engage the index-plate gearing, a supporting-spring connected to either end of said casing and means for securing said spring to said table, substan tially as described.

3. The combination with a Woodworkingmachine provided with a table, of a casing, openings in the front of said casing, indexplates mounted on suitable gears within said casing, independent means of revolving said gears, an operating spur-gear mounted on a sliding sleeve, means for limiting the movement of said sleeve, means for normally retaining said operating spur-gear in engagement with said index-plate gearing, and means for operating said operating spur-gear, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

- BEVERLY G. MOSS.
