CHARLES G. MILLER, OF NEW BRITAIN, CONNECTICUT.

IMPROVEMENT IN CARPENTERS FLOWS.

Specification forming part of Letters Patent No. 131,367, dated September 17, 1872.

To all whom it may concern:

Be it known that I, CHARLES G. MILLER, of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Carpenters Plows, of which the following is a specification, reference being had to the accompanying drawing, in Which- Figure 1 is a side elevation of that side in which the cutting-iron is held. Fig. 2 is a side elevation from the opposite side. Fig. 3 isa plan View. Fig. 4 is a view of the under side of the cutting-iron. Fig. 5 is a central vertical section of the handle through the dotted line a m.

The letter 00 indicates the main body of the plow, cast of metal, in one piece, with ornamental designs thereupon; b, the guide at the left side of the plow, also cast in one piece. The letters 0 0 indicate rods, which are screwed into the side of the main body a, and thereby made detachable therefrom at pleasure, so that the plow can be taken apart and packed into This is believed to be a new feature and an improvement. The guide 1) slides upon these rods, being set at any desired point by means of the set-screws b b, which are placed underneath the rods, and thus out of the way of the left hand of the operator. The placing of these screws in this position is also believed to be new. A knob, b pierced for the introduction of the rod 0, projects from the left side of the guide b, thus affording a support for the left hand of the operator. This also is believed to be new. The cutting-chisel d, commonly called the iron, is secured in its place when in use. by means of the balanced clamp 6, cmbracing the body a, pivoted at e, and operated by means of the cam f, which has an adjusting-screw, f, by means of which the clamp can be made to pinch the iron with as much or as little force as desired. The application of such a clamp to this purpose and in this manner is believed to be new. To the end of this clamp is attached a shaving-guide, f, not greatly unlike, in shape, the mold-board of a farmers plow, which avails to turn the shavings to the right and away from the plow as the chisel produces them from the wood. This combination of a shavin g-guide with the clamp is believed to be new. The iron d is roughened on the under surface, at its base end, for the purpose of taking hold upon the seat h, upon which it rests. The iron also has a lengthwise groove, d, which fits uponthe edge a and thus keeps the iron from any sidewise motion. The base end of the iron rests upon the seat h, but it does not touch the edge a till it comes down where the star is, thus allowing the clamp to spring it firmly down into place, and insuring that the cutting-point of the iron shall set firmly upon the edge a at its lower end, thus obviating any clatter of the iron. This arrangement and construction is believed to be new. Near the front end of the main body a is a gage to determine the depth of the cut of the iron, consisting of the flat metal foot 5, attached to the round pillar i set at any desired point by the set screw i The handle 8 is fastened to the main body a in a peculiar manner. This handle is of wood, slotted on its under side down to the line 8, the width of the slot being just the thickness of the rib a, which rib is pierced with holes a Before'the handle is put on, these holes a are filled with saw-dust and glue mixed, or with pieces of wood having glue upon them,and when the handle is put on the glue sets and thus fastens the handle on. This is also believed to be new.

I claim as my invention- 1. The combination of the cast-metal body a, the cast-metal guide I), and the rods 0 c.

. screwed into the body a so as to be detachable, for the purpose set forth.

2. The combination of the cast-metal body a, the rods 0 c, and the guide b having the set-screws for the said rods under the rods, substantially as described, and for the purpose set forth.

3. The combination of the main body a, rod 0, guide I), and knob I) attached to the guide and pierced for the entrance of the rod, substantially as described, and for the purpose set forth.

4. The balanced clamp e pivoted to the main body a, and operated by means of the cam f, substantially as described, and for the'purpose set forth.

5. In combination with the balanced clamp 7. The construction and method shown for attaching the handle 8 to the main body.
