Machines, of which the following is a speci:

ToaZZ whom it may concern Be it known that I, WILLIAM Hrw ms, a citizen of the United States, residing at Norwich, in the county ofChenango and State of New York, have invented certain new and useful Improvements 1n-Cutt ng fication, reference being had therein to the accompanying drawing.

My invention relates to an improved cutj ting machine, and I declare that the followmg is a full, clear, concise and exactdescription thereof, suilicient to enable one skilled in the art to make and use the same, referones being had to the accompanying drawings in which like reference charactersrefer to like parts throughout. 1

More particularly the invention has to do with a machine which is employed in cutting the ends of boards so that two boards will fit together in an interlocked fashion with projecting ends overlapping, so that when united the boards can be bent in a curve without opening the interlocked joint.

The invention is particularly applicable in the making of an endless clapboard, as it may be called, to be fastened on the outside of a siloto form its outer covering and to provide for a continuous strip frointhe bottone to the top.

In the drawings Figure 1 is a partial side view of the machine, indicating the work .ing table, cutting knives or saws and the feed-plateon which the strips are fed to the cutting members; Fig. 2 is a plan View of the machine on a slightly different scale; Fig. 3 is a sectional view of the feed-plate j with the saws or cutting members and an end of a clapboard being thrust into position for being cut, and Fig. l showsthe two ends of the clapboard to be interfitted; Fig.

5 shows a vertical section on line 5-5 of Fig. l.

Referring to the figures in detail, 1 represents a standard of the maohlne on which is mounted shaft Qwhich carries at its ends a power pulley 3 and has mounted thereon VELPIOHS cutting members, represented at 1,

.in the form of dado saws. The frame or standard 1 has a secondary frame or standard 6 which earrles shaft 8 on which is a power pulley 9, and which shaft also carries other cutting members, here represented as cirrrnveeivmcnmn.

dado saws 10, although a revo can be used wlth the same result.

l 14:; is the feed-platewhieh is bounded on; its sldesby rims 15 wliichare open at the side for the swinging therethrough of the adjustable spring guideslS and 19, seen particularly in Fig. 2. This plate 14: has a series of recesses for the revolving therein of dado saws 1 and 10.

At 20 are shown the cutouts which acc0mmodate the saws 4, which project therefor slightly above the face of the feed-plate 1 L 1 At 21 are shown the cutouts which no coinmodate the saws or knives which therefore revolve slightly below the surfaceof the feed-plate.

The feed-plate has an upward turn, as indicated generally at 25, and on that portion of the plate which lies between the cutouts 20 and 21 is arranged a transversed row of stops 26. The board 30 being fed into the machine meets with the saws or cutters 4 and is cut out at the portion shown by the dotted lines at X in the board 30, Fig. 1. During its passage over such knives the end is raised and passes onward until the part indicated at Y, Fig. 1, butts against the stop 26. In this position, however, the upper cutter has cut avvaythat portion of the board indicated at Z in Fig. 1, and the board meanwhile being lifted by the rise in the feed-plate from unnecessary contact with the cutters 4. After a series of boards have been cut at one end, the

guides

18 and 19 are shifted so that when the other end of the boards are fed into the machine the position of the various cutouts will be alternated and the end board 31 will fit into the end 80 of the next board, an interlocking projecting portion Z and Z fitting under the plane surface of the other board, so that each projecting portion Z and Z" bears against the ving imiaf other board in thecutout portionindicated at X and X, so that the two united boards can be bent in the form of a curve of the same effect as though they were a single board. i p

It will. be apparent to those skilled in the art and from an examination of the drawings that the cutting members or dado saws shown though themselves narrower than the cutouts, will make openings of the width and form shown by reason of the broken or bent construction in which the circular saw is made. 18 and 19 are pins to be positioned to hold the spring guides in proper place for their use.

34 is a cross-piece which holds the work down onto the feed plate, being held by arms 35.

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

1. A machine of the character described having a plurality of cutting members, a feed-table lying between the cutting members and curved to present one surface of an article to be cut to one of the cutting members for a certain extent of cutting and another portion of the article to the other cutting member, and stops limiting the extent of the cutting by each cutting member. 2. A machine of the character described, having in combination with upper and lower cutting members, a table having an upward bend between the cutting members lifting the article to be cut at a given time out of contact with one cutting member and feed ing it to the other cutting member. a I

In testimony whereof I hBI'BLlIltO ailix my signature in the presence of two witnesses.
