UNITED STATES PATENT OFFICE.
AXEL L. LUNDGREN, OF PULLMAN, ILLINOIS, ASSIGNOR OF ONE-HALF TO HARRY W. WOLFE, OF CHICAGO, ILLINOIS.
PLANE.
SPECIFICATION forming part of Letters Patent No. 706,576, dated August 12, 1902.
Application filed January 4, 1902. Serial No. 88,462. (No model.)
tion. I
The object of this invention is to construct a plane which will be strong and compact in to structure, neat in appearance, and easy of adjustment, and the parts of which will, moreover, be firmly and rigidly held in their adjusted positions; and the invention more particularly relates to the means by which this adjustment is accomplished and maintained and to the improvement of the construction and operation of the plane as a whole.
The invention further consists in the features of construction and combination of parts hereinafter described and claimed.
In the drawings illustrating the invention, Figure 1 is a side elevation of the plane of this invention; Fig. 2, a side elevation showing one of the sides of the stock or'frame cut away, exposing the adjusting mechanism within; Fig. 3, a top or plan view with the cap or cover removed, and Fig. 4 a top or plan view with the wedge and bit removed from the stock: or frame.
The plane of this invention is made with a stock or frame A, which may be of metal or other suitable material having side walls a, a front end walla, a rear end wall o beveled at its upper corner, and a bottom or sole 0L3 for contact with the wood to be planed, and an escape-opening A in the side walls and a mouth a in the sole to allow for the projection of the bit therethrough and the escape of shavings from within the stock. Between the side walls and abutting against the interior of the rear end wall and the bottom or sole is a bed B, having an inclined upper face and made of wood or other suitable filling materialprovided with a forward recess b in itsupper edge and a rear recess 5 in its rear edge, leaving a lug or bearing 1) between the two recesses, and into the forward end face of the recess 1) extends a bearing-hole b (Shown in dotted lines.) The bed may be held in position within the stock by a screw 0 or other suitable means.
ment.
An adj usting-screw O,extending diagonally through the beveled corner of the rear wall, through the lug or bearingb of the bed B, and into the bearing-hole 19 is provided at its free end with an adjusting thumb-nut 0, bearing against the exterior wall of the stock or frame, and with a ring or collar 0 within the stock or frame, which allows the adj usting-screw to revolve and prevents its withdrawal or displace- 6o Carried upon the adj usting-screw and'lying within the forward recess is a travelingnut D, having on its upper face a pin or pivot d, projecting into a hole 6 in a bit E, the cutting edge of which bit projects through the mouth in the sole or bottom and the body of which rests upon the inclined upperface of the bed B, thereby affording a means for adjusting the bit by imparting movement to the traveling nut.
The bit is provided with an outwardlyflaring cutting-head e, and its radius of adjustment may be further increased by increasing the number of holesc, as shown in dotted lines. A clampinglever-block F, hav- 7 5 ing in its upper face a longitudinally-extending slotfand a depression f, leaving a contact-shoulder f and also provided with a bearing-plate f attached to its face, afiords a means for holding the bit firmly in its adjusted position. A lever G, working within the slot, is provided with a cam head g, through which extends a pivot-pin g, carried by cars g formed in the bearing-plate and bent or turned to hold the pin firmly in place. A flat spring H, fixedly attached to the under face of the bearing-plate f at the point h, has its free end in contact with the lug of the bed and is pressed down against the lug under tension by the cam-head G of the lever when down, thereby holding. the bearing-plate of the clamping lever-block in rigid contact with the bit, and a bearingscrew I is screw-threaded into an abutment c'between the side walls of the stock or frame. The abutment is adapted to contact with the shoulder f in the upper face of the clamping lever-block to prevent the clamping lever-block from being carried forward beyond its proper point of adjustment while the bear- 10o ing-screw serves to regulate the degree of pressure exerted by the bearing-plate of the clamping lever-block against the upper surface of the bit. I
A filling-block J, held in place by a screw j or other suitable means, serves to add rigidity to the forward end of the stockor frame and to prevent the same from being clogged or filled up with shavings or other refuse, and a cap K, adapted to enter the opening in the stock or frame and provided with a depression or recess is in its under face for the reception'of the clamping leverblock, and further provided with a flaring outwardly or extended top 70', projecting over the walls of the stock or frame, affords a suitable rest for the hand when in use.
It will thus be seen that the plane of this invention may be quicklyand readily adjusted while in use without removing any of its parts by merely turning the adjusting-screw and projecting or receding the bit operated thereby. The clamping lever-block, with the lever-block released from contact with the in use.
adjusting-screw may be withdrawn from the stock or frame, allowing the bit to be subsequently removed. The action of the spring in raising the clamping lever-block at itsrear end brings the contact of the bearing-plate of the clamping lever-block close to the cutting end of the bit at the point where the pressure is most needed, thereby serving to better hold the bit against displacement when Moreover, by bringing the entire pressure of the bearing-plate upon a single portion of the bit the bearing-plate is made .tobind or bite against the bit, thereby rendering the pressure more effective than if exerted by continuous contact between the clampinglever-block and the bit. It will thus be seen that the plane is simple and effective in. its operation, easy in its adjustment, and strong and neat in its construction.
What I regard as new, and desire to secure by Letters Patent, is
