JAMES MURRAY AND FREDERICK W. HOLT, OF ST. GEORGE, NEW BRUNS- WVlCK, CANADA, ASSIGNORS OF ONE-THIRD OF THEIR'RIGHT TO ABRAM J. MGGEE, OF SAME PLACE.

LATH-BOLTER.

SPECIFICATION forming part of Letters Patent No. 226,537, dated April 13, 1880.

Application filed January 30, 1880.

To all whom it may concern Be it known that we, J AMES MURRAY and FREDERICK W. Hour, of St. George, in the Province of New Brunswick and Dominion of Canada, have invented certain new and useful Improvements in Lath -Bolters and We do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part of this specification.

Our invention relates to an improvement in lath-bolters and it consists, first, in the arrangement and combination of parts whereby the table is made to reciprocate back and forth automatically before the saw second, in a mechanism placed beside the saw for moving the bolts as fast as they are cut off over to elevators, which elevators carry them up at any desired angle and drop them over upon a slideway third, in the arrangement and combination of parts that will be more fully described hereinafter.

Figure 1 is a plan view of our invention. Figs. 2 and 3 are end views of the same. Fig. 4. is a side elevation. Figs. 5, 6, 7, and 8 are detail views.

a represents a suitable frame, which may be of any desired construction, and b is the driving-shaft, which is journaled in the frame and provided with a pulley, c, for driving the saw, a plain or cone pulley, (I, over which a crossed belt runs, and a pulley, e, for an open belt.

Upon the shaft f are placed two pulleys, g h, which correspond to the two d e, and which two, 9 h, are loose on the shaft f, and are only brought into operation when the clutch h is forced against either one by the rod 1 which 4 extends across the machine to where the operator is. On the outer end of this shaft f is a gear, which meshes with and operates a sec- 0nd gear on the shaft j, which shaft is heldin the journaled box 70 at its outer end, and atits inner end in the box formed in the end of the pivoted arm or lever l, and which lever is made to keep the pinion 0 on the inner end of the shaft always in gear with the rack m by means of the spring a. By thus having the shaft journaled in two movable boxes the pinion 0 can be raised and depressed, so as to work equally Well either on top or in the under side of the rigid rack. This rack is placed on the lower part of the carriage q, and is provided with a suitable guide, 1), at each end, to guide the pinion 0 in the proper direction when it reaches that end.

By means of the mechanism above described the carriage is automatically moved back and forth before the saw. Should the operator at any time desire to stop the carriage or reverse its motion, he has only to move the rod 2' and. shift the clutch h.

On the inner end of the driving-shaft bis a pinion, 1, 'which meshes with the gear 8 on the shaft t. On the inner portion of this shaft t are several spur-wheels, which operate a corresponding number of endless elevators,

a, which elevators are provided with hooks or other suitable devices for carrying up the bolts after they are cut off by the saw.

On the outer end of the shaft 2? is a pulley,

o, from which passes a belt up over the pulley won the shaft 00-. This shaft runs along parallel with the saw, and is provided with suitable spurs or other devices, which project up through the covering placed above the shaft, and which spurs catch the bolts as fast as they are cut off, and move them over to where the elevators can take hold of them.

Parallel with the saw, and placed close be side it, is a flange, y, which causes the bolts to separate from the saw as soon as they are free to do so.

The elevators carry up the lath or bolts and 85 drop them over upon the inclined slideway z, from whence they can be carried in any suitable direction.

Having thus described our invention, we claimo 1. In a lath-bolter, the combination of the carriage q, provided with the double rack m,

and a guide, 19, at each end of the rack, with the shaft 3', which has one end journaled in the pivoted block 70 and the other end in a lever, l, which is supported by the spring at, and which shaft is provided with a pinion, 0, sub- 7 stantially as shown.

2. In a lath bolter, the combination of a carriage for moving back and forth before the saw, a shaft, w, running parallel to the saw, and provided with wheels or arms for moving the laths away from the saw as fast as they JAMES MURRAY. 14. s.] FRED. W. HOLT. 1,. s.]
