Letters Patent No. 98,898, date'rlJmtua/ry 18, 187 0.
l IMPROVEMENT IN MACHINERY FOR SAWING- LAT'BI.
' The Schedule referred to in these. Letters Patent and making part of the same To whom it may concern to the letters of reference marked thereon, and being a part of this specication, in which- Fignre l is a plan of my improved machine, :nd
Figure 2 is an elevation of the saine.`
Like letters refer to like parts in each figure.
The object of the present invention is to combine, in one machine, a rip-saw, agang of splitting-saws, and an automatic feed-motion, for the purpose of sawing, frornbolts of timber, lath, six, more or less, in number, at each reciprocation of the saw-table, and consists in the peculiar arrangement of its parts, necessary for the accomplishment of the purpose designed.
In the accompanyingdrawings- A represents the frame of the machine, upon which are secured suitable ways a.
B is a carriage, supported by wheels b, travelling on said ways.
A' is an offset or lateral extension ofthe main frame, on its rear side. p
O is a circular saw, mounted on a shaft, C', journaled in boxes on the rear beam of the frame A, and
' that of the frame A', the saw overhanging the front side of the rear beam, as shown. To this shaft motion is communicated by a belt passing over Athe pulley c.
In the lower part of the frame A' is journaled a countershaft, D, to which motion is communicated byl a belt passing around the pulley d secured thereto, and the pulley d on the shaft C.
Ir. proper boxes, in the upper part of the frame A A', is journaled a feed-shaft, E, whose inner end projects between the front and rear beams of the frame A, under the carriage, where it is provided with a pinion, F. Between its bearings it has sleeved ou it two clutch-pulleys e e.
Feathered on the shaft E isa double clutch, G, operated by a bell-crank lever, H, so that it will engage with either of the clutches e.
On the countershaft D are two pulleys, f and f,
around each of which, an"d the clutch-pulleys c e', are
passed belts or cords, that between f and e being crossed, as shown in fig. 2, so that when .the clutch is in gear with the pulley e the shaft E will rotate, to feed the carriage toward the-saw, a rack, I, being placed under the carriage, with which the pinion F meshes for that purpose. IVhen the clutch is in engagement with the pulley e the motion ofthe shaft E is reversed, and the carriage reccdes from the saw. p
. J is a shifter, provided with two upward-projecting stops or studs jj'. From the under side of the table Orcarriage two similar or corresponding studs k k depend, the studs on the shifter which is pi'voted to the clutch-lever H, and those of the carriage, being so arranged, that wh'en the carriage has receded far enough from the,saw,the stud 7c strikes the stop j, carrying along the shifter, until the motion of the feed-pinion F is reversed, and the carriage is fed up and past the saw C, with its bolt, when the stud It strikes the stop j', and the motion 'of the pinion is again reversed.
K are head-blocks, sliding in the transverse open YWays L of the carriage, and whose distance from each other is the length of a lath-bolt, which is held between their ends bythe dogs t' i', the latter of which is pivoted to its head-block, and is provided with a lever; by which it is forced into the end of the bolt. The head-blocks are also provided with toothed racks on their under sides, with which mesh the vpinions m at either end of the `shaft M, which is journaled in the under part of the ways L.
On the shaft M is secured a ratchet, N, and sleeved on the shaft, so as to embrace the ratchet, is a ratchetlever, N', whose pawls u engage with the ratchet.
As the carriage recedes from the saw, the' pendent end of the ratchet-lever is thrown out by a cam, O, projecting from the side of the frame, causing the shaft M to rotate, and move the head-blocks forward the width of a lath at each reciprocation of the carriage.
A lever, J', is also pivoted to the shifter, so that l the attendant may disengage the clutch G from either clutch-pulley, if it is desired to stop or reversev the motion of the carriage.
I is a vertical saw-mandrel, on which is ypulley P', which, by a belt, is rotated from any convenient source.
Q are circular saws, in any desired number, secured' to the upper part of the mandrel, with collars placed between them ofthe thickness of a lath.
The boxes in which the mandrel-P rotates, have a.v vertical sliding movement in the guides p, the lower of which is shown in iig. 2. This movement is effected by the lever It, pivoted to the rod 1', which is secured to and connects the upper and lower box, insurin g theirequal movement. A
In operation, the saw-mandrel P will be habitually raised up, to allow all the saws to operate in the slab or bolt, to reduce it to lath; but, should there be a knot or other imperfection in the upper surface ofthe slab, (from which lath are principally made,) the saws may be dropped, so as not to encounter the obstruction.
Bolts, of the length of lath, are sawed from slabs,
in motion. At the first forward motion of the oarriage, the saws Q eut into the faee of the bolt a series of kerfs, each as deep as a lath is Wide. Passing on, the saw O rips them off, and they fall into a rack conveniently placed to receive them. When the cut is completed, the motion of the pinion Il" is reversed, in the manner already described, and the carriage gigs back from the saw.v In so doing, however, the ratchetlever N is .thrown-outward by the stationary cam 0, when the head-blocks are moved forward the width 'of a lath, when the carriage again approaches the saw,
vand a second cnt is taken from the bolt, the operation being repeated until the entire bolt is converted into lath.
What I claim as my invention, and desire to secure by Letters Patent, is v In latki-machines, the employment of an automatieal y-reversing feed-device, consisting of pulleys d d f j, clutch-'pulleys e e', clutch G, lever H, and shifter J,
riage, B, `the Whole arranged and operating substan tially as and forthe purposes set forth.
