PLANE.

To all whom it may concern Be it known that I, HERBERT G. C LLINS,

a citizen ofthe United States, residing in the city and county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description. I This invention relates to planes, and more particularly to the means for adjusting the cutter and clamping it in position.

The improvements. are particularly applicableto molding planes, but may also be used in connection With planes of other types.

The primary objects of the invention are to provide'improvedand simplified means for clamping the bit or cutter in the desired adjustment; to furnish simple and effective means for adjusting the cutter longitudinally; and to improve the general construction and operation of devices of the class to which my invention relates. I

To these and other ends, the inventionconsists in the novel features and combinations of .parts to be hereinafter described and 'anenlarged section on line 5'5 of Fig. 1;

Fig. 6 is a detail showing the clamp in position to release the bit or cutter; Fig. 7 is a detail showing the seat for-the cutter-and clamp; Figs. 8, 9 and 10 aredetails of'the clamp; Fig. 11 is a detail of the clamping nut; Fig. 12 is a detail of the clamping nut socket; Fig. 13 is a'section on line '13' -13 of F ig. 1; and Fig. 14 is a-detail of thebit or cutter;

Referring to the drawings, I have shown my improvements applied to the main stock 20 of a molding plane, which stock is provided with a handle 21 and throat -22 of usual form. Aibit or cutter 23 is clamped against the side of the stock by means of a clamp 24 in such a manner as to project into the throat 22. The clamp-21B operated by a clamp .nut 25 located at that side ofthe stock opposite the cutter, and the'c'utteris Specificationof Letters Patent.'.

adjustedlengthwise, 2'. 6., into and out of the throat 22 bymeans of an-adjustingscrew 26,

engaging a-threaded socket 27 at the topof the stock and cooperating with the cutter in the manner to be presently described.

I Referring particularly to Fig. 7, it will be noted thatth'e cutter 23 andclamp 24: are partiallyaccommodatedin a recess or seat 28 formed in one side' of the. stock. lower portion of the recess is a laterally extending ledge or flange 29, which assists in supporting the cutter from beneath. Oppo-' site the ledge 01' flange29,,2'. eQ, atatheftop of At the the recess 28, is a somewhat similar projectj lng ledge or flange 3O, against which fits the upper edge or surface of-the clamp 2%. The lower or under surface 31 of the ledge 30 is located in'a plane somewhat out of perpendicular with respect-to thev vertical longitudinal plane of the stock, andsaid surface 31 cooperates with a correspondingly inclined surface 32 at theupper part of the clamp.

The lower surface-33 of the clamp is parallel with the cutter seatingsurface of the ledge 29.. .The cutter is clamped tightly in its seat by drawing the clamp :24.-:laterally into the recess 28. In doing this, -,the inclined surefaces 31,32 of the ledge and clamp24 respectively cooperate insuch a manner as to tightlyagainst the cutter..' I I IIII the embodiment sho wn,;.the clamp24c force the lower surfaceg33 of the clamp is adjusted by means of a threaded shank;

.35 extending laterally therefrom througl i' .anopening 36in the stock, and engaging interior threads of the. clamping nut 25. previously mentioned. The opening or bore 36' in the stock is of somewhat greater-diameter than the shank 35, so .that the lat- 1?" ter will have a certain amount 'of clear.- ance. The nut 25 is suitablyfix'ed against lengthwise movement, as by means of a collar-37 en a in aorooved socket38 at V h D h b thesiole of the stocln'asshown in Fig. 4:.

Assuming that the shank 35 and nut 25 are provided with the 'usualright-hand threads, rotation of-thenut 25 infaclockwise direction will draw the clamp-24 laterally into its-seat to clamp the cutter tightly in position, a' sshownin Fig. 3. hen the nut.25

is turned in a counter-clockwise direction,

the clamp'24ewill' be -forced laterally out of its seat, andgtheclearance in the bore35 will allow the clamp to swing away from I axially of the and releasethe cutter as the inclined surface 32 of the clamp slides outward along.

the cotiperating surface 31 of the stock.

In assembling the device, the nut 25', which preferably has a circular milled head, is entered laterally into its socket 38, which is permitted by having said socket open throughout a portion of its periphery, as shown at 88 in Fig. 12. As the nut is slipped into its socket, it will be held against lengthwisemovement by the engagement of its collar 87 with the corresponding groove in the socket, and the shank 35 of the clamp will be passed through the hole 86' to engage the threads of the nut in an obvious manner. As the nut is held against dis placement in an axial direction, the clainp 2e must move laterally into and out of its seat, as the nut is turned in opposite directions I respectively. During the inward movement, the portion 30 of the stoclr acts as a cam to force the clamp toward the out ter-supporting portion or ledge. In the out ward movement of the clamp, the clearance around the shank of the latter periiiits the clamp to move away from the cutter;

The lengthwise adjusting screw 26 for the cutter is provided with a filled head 26 having at its lower portion an annular shoulder 26*. The shoulder 26 projects ax iallyrelative to the adjusting screw. Be low the shoulder 26' is a shoulder 26 pro jecting perpendicularly relative to the ad justing screw. The shoulder 26 engages a notch 23 formed in the side of the cutter, so that as the adjusting screw is'turned in one or the other direction the cutter, will be moved into or out of the throat. The shoulder 26 of the adjusting screw engages a notch 23 at the top of the cutter and ef fectively holds the cutter in engagement with the shoulder 26. Movement of the cutter iii an outward direction relati ely to its seat, 2'. 6;. away from the side of the stock, is

prevented by the engagement of the shoul= dei 26 with th'enotch 23. and by the eugagement of the clamp with the body pertio'n' of the cutter. I

' T he foregoing description isnecessarily a detailed one in so far as'it concerns the particular embodiment of my in ention'selected for illust ation.

Various mod ficat ons of the construction may be ado ted within the scope of jthe invention as defined in the claims.
