PLANE.

SPECIFICATION forming part of Letters Patent No. 279,885, datedJune 19, 1883. Application tiled February 24,1883. V(l\'omodel.)

To all whom, t may concern/.-

Be itknown that we, SoLoN R. RUs'r and AR- TEUR E. RUST, citizens of the United States, residing at Pine Meadow, in the county of Litcheld and State of Connecticut, have invented certain new and useful Improvements in Beneh-` Planes; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in Io the art to which it appertains to make and use the same.

Our invention relates to improvements in what are termd blo ck-planes ,7 and the obj ect is to produce a Vplane in which the bottom or face of the plane can be easily adjusted to the ,iron by means of a hinge motion in back part of plane, and to produce a clamping-bar with central point bearing against a central bear-- ing, cast solid with the frame without a core,

2c and to form a cheek-nut and knob on the adjusting-screw, and also to simplify the general construction and operation. 4

Our invention consists in constructing a block -plane so that the plane bit or iron which projects through the mouth or opening can be adjusted, as desired, to form an open or close mouth, andto suit the nature of the work to be performed in an expeditious man- Y ner. The bottom or face of the plane is hinged 3o to the rear part ofthe skeletonframe or stock,

and is adjusted by means of a iiat wheel on an adjusting screw or stud, and fitting with one side under lugs cast on the frame at its front end, and with the other side against two cross- 3 5 bars, also east on said frame, v A check-nut and knob on saidadjusting-screw secures and locks the wheel in place. .n

It also consists in holding the bit or planeiron in vplace by a screw in the clamping-bar 4o against said iron, while said clamping-bar bears with its upper side against a central point east solid in the frame, and which forms a fulcruin for it. The lower side f the planeiron rests against two cross-bars, also east sona with the name.

It also consists in adjusting the open and close mouth without a movable front piece;y

and it also consists in the construction and arrangement of certain parts of a plane, as will cifically pointed out in the claims, reference being had to the accompanying drawings and the letters of reference marked thereon.

Like letters indicate like parts in the different figures of the drawings, in which- Figure l represents a side elevation of the plane. Fig. 2 is a top view of the same. Fig. 3 is a longitudinal sectionvof the same. Eig. 4 is a top view of the bottom of the plane. Fig. 5-is a longitudinal section of the same. Fig. 6 is a longitudinal section of the frame. Fig. 7 is a top view of the same. Fig. 8 is an end view of the same.

In the drawings, A represents the skeleton frame or stock,consisting of the side pieces, a a, connected by a series of cross pieces or bars, one of which, b', forming the hinge-pin for the bottom B, and another one, c, being the central bearing for the clamping-bar C; The bottom is provided with a lug, b, into which the 7o bar b fits, and is held in place by a clampingplate, b, and screw b. At the forward end of the plane is arranged a screw, D, upon which a dat milled wheel, E, is screwed, tting with its upper surface under lugs d, cast 7 5` on each side or wall of the frame, and with its lower surface bearing on two bars, e and f. A milled clamping-screw or cheek-nut, F, secures the wheel in its locked position. By this arrangement the bottom or face of the 8o plane can be adjusted to a nicety to the plane iron or bit. The bars c and f are provided with raised parts c and f to form a more perfeet adjustment for the wheel. The clampingbar C secures thefplane iron or bit G in posi- 8 5 tion by means of a screw, g, which forces the bar C against a central bearing, h, on the bar c, cast solid with the frame and without the use'of a core. The lower side of the plane iron or bit rests on two cross-bars, fi 7c, also 9o east on the frame. The bottom is provided with two curved ears, Z, which fit closely into corresponding recesses formed in the frame, and they serve to hold the bottom in position and prevent any lateral movement. `It will be readily seen that by screwing the face or bottom close down or tight, and setting the iron or bit, an open mouth is formed; and by letting the face or bottom down and then setting the iron or bit a very close mouth is ob- Ioo l tained. A much greater pitch is also obtained by having the adjustment at the 'front end of the plane than if on the back under the cutting-iron, which is a great advantage, as it makes a much smoother cut. The bit can be adjusted nicely to coarse or line work.

Having thus described our invention, what we claim, and desire to secure by 'Letters Patent, is-

1. In a plane, a fiat wheel, E, for adjusting the size of the throat ofthe plane, and having its bearings on the bars e f and, under lugs d, as shown, in combination with ascrew, D, secured to the hingedbottoni B, substantially as specified.

2. The adjustable bottom B, hinged at the rear end of the frame A by means of a bar, b, having bearings in a lug, I), and held by a clamping-plate, b, and adjusted at the front end by a screw, D, and wheel E, in the inanner shown and set forth.

3. The frame A, provided with a bai', c, having a central bearing, h, for forming a i'ulcruni for the clamping-bar C, provided with a screw, g, by which the bit G is held in place in the plane, substantially as speciiied.

4. The skeleton frame A, provided with bars e f and lugs d d, forming bearings for the wheel E, a bar, c, having central bearing, Il., against which the clamping-bar C bears, and the pivot-bar b, forming the hinge-bar for the adjustable bottom, and all cast in one piece, as set forth.

5. rlhe method of and means herein d cscribed for adjusting the bottoni B to form an open provided with curved ears Z, fitting into corresponding recesses in the sides of the skeleton frame A, with a bit, G, held in place by a clamping-bar, G, and thumbscrew g, the stationary screw D, and wheel E, for adjusting the bottom, substantially as described, and for the purpose set forth.

8. The plane herein described, consisting of the skeleton frame A, to which the bottom. Bis hinged adjustably, in combination with a screW,'D, clamping-wheel E, check-nut F, bit G, clanipingbar C, with screw g, and Central beaiiiigpoint, all constructed and ar- ,ranged substantially as specified.

In testimony whereof wc hereby afiX our signatures in presencel of two witnesses.
