The jour sired completed lath; but we do not desire nal-bearing boxes 16 are adjustably mounted to be understood as limiting our invention upon the arms 17 and 18, depending from the solely to this combined action, since, as will under side of the table-top 19, these arms 50 subsequently appear, the lath-making mechbeing of such construction and so disposed I00 as to conj unetively maintain the shaft 14 in a diagonal position relative to the table-top when the saws (about to be described) are being used to dovetail grooves in the lath. The arm 17, it will be observed, has a straight portion and an extension 21 arranged angularly relative to the straight portion 20, whereas the arm 18 is simply disposed at an angle relative to the table-top 19. On one end of the arbor 14 are the saws 22, 23, and 24, said saws being of relatively decreasing diameter, so that the same may conjunctively act upon three diiferent grooves 25 in the lath 26 at one and the same time. It is evident, however, that any number of saws may be used, depending in each case upon the width of the board in which are the grooves 25. It is now evident,by reason of the diagonal position in which the arbor 14 is held and the diminishing diameters of the saws, that a plurality of grooves 25, having square sides, may be formed dovetail on one side during one movement of the board forward against the saws, and that by simply reversing the board and again passing the same through the machine the other side of the grooves are also formed dovetail.

The saws are spaced and held apart by means of the washers 27, which washers, when joined together, form the hub 28, Fig. 2. These washers 27 may be of various different widths, so that the saws may be positioned apart and brought into the right relation to the grooves 25 of the lath 26. The position. of the arbor l4 and saws thereon is adjusted by means of the adj listing-bolts 29 and nuts 30, (shown by the dotted lines in Fig. 2,) and is also capable of endwise adjustment, being held in position by the collars 31 and setscrews 32, the adjustingbolts 29 moving within the slots 33 in the arms 17 and 18. Adjusting-screws 34 are also provided, secured to or bearing against the journal-boxes 16, which screws pass through the lower ends of the arms 17 and 1S and are held in position by means of the jam-nuts 35. The slots 33 in the arms 17 and 18 are of such length that by loosening the collars 31 and adjusting the arbor 14 endwise the said arbor may be disposed at any desired angle relative to the table-top 19, and thus the required dovetail of the grooves 25 may be obtained and also permits a positioning of said arbor in parallelism with the table-top 19, so that the saws may be employed for any desired purpose, being in a vertical position, either to form the square-sided grooves 25 by providing saws of suiiicient width, or to cut the kerfs 36, or a single saw or set of saws may be employed for any one of the many numerous uses of circular saws.

I11 order to employ this described lath-making mechanism,in conjunction or combination with a matching-machine, it is simply necessary to remove the top plate of the end portion of the matching-machine and then dispose the lath-making mechanism within and between the side pieces 33 of the matchingmachine frame 10, the tabletop 19 of the lath-makin g mechanism being bolted in position on said frame 10 and substituted for the end plate of the matching-1nachine. By this construction and arrangement we are enabled to completely inclose and incase the lath-making mechanism within the frame of the matching-machine, and thus dispose the lath-making mechanism so that the same is entirely out of the way and in such position as to be belted directly with the main driveshaft of the matching-machine or with the mill-shaft, and thus reducing the power necessary heretofore to drive the saws of the lath-makin g mechanism. The pulley 15, being disposed between the journal-boxes 10, distributes the frictional wear evenly, and in conjunction with the arbor 14 permits an alignment of the pulley 15 with the pulley 12 on the drive-shaft 1.1 of the matching-machine, so as to avoid any obstruction on the matching-machine.

It is evident that the arbor 14 and saws may be disposed in such a manner as to provide a left or right hand machine, or double arbors and two saws or sets of saws may be employed in a manner as embodied by us in a machine for which application will be made for patent.

Referring now to the means for holding and guiding the board in its movement through the saws, (shown more particularly in Fig. 3,) the guide-pieces 37 and 38 are disposed upon the upper side of the table-top 19, the guidepiece 37 being held adjustablyin position by means of the bolts 39, passing through the slots 40 in the arms 41 extended from the guide-piece 37, and also through the slots 42 in the table-top. The guide-piece 38 is adjustably held, by means of the bolts 43, in the slots 44, and is also held by means of the bolt 45, which serves to steady that portion of the guide-piece 38 extended beyond the table-top 19. By this means the guide-pieces may be adjusted for any width of board and the guide-piece 37 may also be held in a position removed some distance from the guide 38 by securing the bolts 39 through the supplemental slots 46, thus permitting the passage between the guides of any material acted upon by the matching-machine without encountering obstructions at the lath-making machine.

The tabletop 19 is slotted at 47 to permit the saws to protrude beyond the plane of the top of the table, and openings 48 are provided which give access to the working part of the lath-making mechanism.

Referring now to Fig. 1, it will be observed that we have provided rotatin g cutting-knives or cutters 49, mounted on, preferably, the upper cylinder 50 of the matching-machine, and also the cutting knives 51, mounted, preferably, on the lower cylinder 52 of the matching machine, the rotated cutters 50 being adapted to cut the kerf or groove 36,

means of the saws.

Figs. 2 and 5, in the board 26 and the cutters 51 being adapted to cut the groove 25, which latter is subsequently dovetailed by It may be desired, however, to form one side of the groove 25 by means other than the saws, and we have therefore shown the stationary cutters 53, Figs. 1 and 3, held in a stationary position and inclined forwardly and diagonally.

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

1. The combination with a matching machine, of a sheating lath making mechanism, comprising a table-top disposed on the end portion of the matching machine, arms depending from the under side of said tabletop and inclosed within the frame ofthe matching machine, an arbor rotatably held by said arms and saws fixed on said arbor, and means for driving the arbor and saws.
