IMPROVEMENT IN CARPENTERS’ PLANES.

To all whom it may concern:

Be it known that I, GEORG MÜLLER, of the city, county, and State of New York, have invented a new and useful Improvement in Carpenters’ Planes; and I do hereby declare that the following is a full and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making part of this specification, in which —

Figure 1 is a top view ofi a carpenter’s plane containing my invention; Fig. 2, a side elevation, and Fig. 3 a vertical section, of same. Fig. 4 is an under side view of the retaining-box in connection with the sliding cap-iron; Fig. 5, an inner view of retaining-box with cap-iron removed; Fig. 6, a plan of the sliding cap-iron, and Fig. 7 a longitudinal section of said iron.

This invention relates to a novel device for adjusting the cap and bit-irons of a carpenter’s plane in relation to each other and to the plane, and holding the same firmly in position by means of a swinging box or frame, which is pivoted to the plane-stock, and on which the cap-iron slides, the said box having set-screws for adjusting, retaining, and bracing the box, cap-iron, bit-iron, and plane-stock together, and at the same time rendering the cutting-irons capable ofthe nicest adjustment and stability in relation to each other and to the face of the plane-stock.

Having described the nature of my invention, I will now describe its construction and mode of operation.

In the drawings, A is the plane-stock, B the handle, and C the plane-iron or cutting-bit. D is the cap-iron, having projections e e, which slide on the ways of the box, and having, also, a lip or projection, f, at right angles to its face, in which set-screws (which pass through the end of the box marked g g g’) operate, for purposes hereinafter explained. H is the retaining-box, which receives the cap-iron D, and has ways i i, on which the projections e e of the cap-iron slide, while the projection or lip f of said cap-iron slides on the interior of the box, Fig. 4. This box H is pivoted to the plane-stock at k, and has a clamping-screw, m, for the purpose of bracing the cap and bit irons together, and against the rear, a, of the throat of the plane-stock.

To arrange my plane for operation, I place the bit C in the throat a of the plane-stock. I next set the cap-iron D within the box H and insert the adjusting and clamp screws in their places, and I place the box so equipped in the throat of the plane. I now pass the pivot k through the throat of the plane, and through the box H; and for adjustment of the cap-iron in relation to the bit-iron in a longitudinal or transverse direction I simply turn the screws g g, or either of them, (as the case may be,) back or forth, and when so adjusted hold the cap-iron D in position by the screw g’, abutting against the lip f of the cap-iron, and I next clamp the whole together by means of the screw m, when my improved plane is ready for operation.

It will be seen from the above that by means of the pivot k and clamping-screw m the box H, cap-iron D, and bit-iron C are braced firmly together and against the plane-stock, equally distributing the pressure over the surface of the part a of the throat of the plane: Furthermore, by this arrangement the box H closely tits the throat of the plane laterally, the movements of the cap-iron being pertormed within the box; besides, the box can be brought near the mouth of the plane, thereby giving strength and stability to the cutting-irons, and at the same time easy exit to the shavings, for the reason that I dispense with the prize fork or carrier F, used in the subject of a patent granted me on the 29th day of May, A. D. 1866, and on which I consider my present invention an improvement, inasmuch as the swell on the box E, for reception of the prize-fork, prevented the approach of the box toward the mouth of the plane or end of the cutting-irons, rendering the said irons partially unstable, while it also prevented the easy exit of the shavings, or rather tended to choke the throat of the plane; and, besides this, the said box E was slotted for reception of the joint-pin G, and did not fill the throat of the plane laterally, as provision had to be made for the lateral movements of the cap-iron, and both the box and prize-fork were slid together, while in my present improvement the box H is stationary, while the cap-iron D slides transversely and longitudinally on the ways of the box; and thus I produce an improvement on my former plane, which can be manufactured for two-thirds of its cost.

What I claim as my invention, and desire to secure by Letters Patents, is —

The arrangement of the stationary box H, pivoted to the plane-stock, and fitting closely the the throat thereof laterally, in combination with the cap-iron D, which is moved and adjusted beneath the said box, substantially as and for the purpose herein specified.

In testimony whereof I have hereunto set my signature this 21st day of August, A. D 1867.

IMPROVEMENT IN CARPENTERS’ PLANES.

Specification forming part of Letters Patent No. 55,207, dated May 29, 1866.

To all whom it may concern:

Be it known that I, GEORG MÜLLER, of the city, county, and State of New York, United States of America, have invented certain new and useful Improvements in Carpenters’ Planes 5 and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which —

Figure 1 is a top view of a carpenter’s plane with my invention applied to it. Fig. 2 is a side elevation. Fig. 3 is a vertical section. Fig. 4 is an edge view of the bit-iron; Fig. 5, an edge view of the cap-iron or base of the sliding box; Fig. 6, a view of the sliding box with its slots; Fig. 7, a view of the sliding box in connection with the joint-pin, forked prize-piece or carrier, and set-screws; Fig. 8, an edge view of said prize-fork, and Fig. 9 a plan of same.

This invention relates to a carpenter’s plane in which the plane-iron or bit is so placed in relation to the plane-stock that the cutting-edge of the bit shall be forward of or projected beyond the forward end of the plane-stock, for the purpose of planing into the angles of stationary or framed carpenter-work, whether of square or molded form, and thus enable the carpenter to rent his doors, window-sashes, &c., to their frames with facility and dispatch; and, besides this, the cap-iron is so applied to the bit and to an adjustable or sliding box, which is pivoted in the plane-stock, as to render the plane-irons or cutters capable of the nicest adjustment and stability in relation to the plane-stock by means of a carrier or prize-fork within the said box and its set-screws.

Having described the nature of my invention, I will now explain its construction and mode of operation.

In the drawings, A is the plane-stock; B,the handle, and O the plane»iron or cutting-bit. D is the cap-iron, with its lips or projections d d, for reception of the box E. The box E has slots e e, through which the joint-pin G passes, and contains a forked carrier, F, the said carrier having holes through the arms f f for reception of the joint-pin or pivot G, which passes through the said arms f f, the box E, and the plane-stock A. The carrier is sustained and stopped at its opposite end by set-screws g g h, as shown in Fig. 7. There is also a thumb or clamping screw, I, which passes through the box E, between the forked arms of the carrier F, and abuts against the cap-plate D, for the purpose of bracing the irons G and D against the plane-stock A. The front end of the plane-stock, A’, or that part of it in front of the bit G, which, with the plane-stock A, forms the throat a’, I make of iron, steel, or other metal, of the form shown by the red line a’ a’, if desired. The bit C tapers toward its cutting end, and has a boss, x, on its outer end to aid in adjusting the same.

The operation of my invention is very simple, and is as follows: In the first place, I put the bit C in the throat a of the plane-stock A. I next set the forked prize-piece F within the box E, and insert the set-screws g g and retaining-screw It in the box and carrier. I then screw the clamping-screw I through the box, so as to abut against the cap-plate D. I now set the box on the said cap-plate, between the lips d d, and the box, thus prepared, I place in the throat ct of the plane-stock A, on the bit C, and I pass the joint-pin or pivot G through the iron throat a of the plane-stock, through the box E, and the carrier F.

To adjust the cutting-irons in relation to each other and to the plane-stock in a longitudinal direction will be simply to turn the screws g g, when the cap D will be carried by the box E in the direction of the mouth of the plane; or, by a reverse motion of the screws, the said cap will be carried back from the said mouth because of the carrier F being held by the joint-pin G; and should a transverse adjustment of the irons be necessary, the same can be done by slackening one of the screws g and screwing the other up. Now that the irons are properly adjusted to hold the same firmly in position, I clamp the screw I and the bearing-screw lt, when my improved plane is ready for operation.

It will be seen from the above that in the application of my invention to a plane-stock the box E is made a lever, of which the joint-pin G is the fulcrum, and the power being applied through the clamping-screw I, the pressure is exerted against the cap-plate D and the bit C, in consequence of which the said pressure will be equally distributed on that portion of the surface of the throat of the plane on which the bit C rests, and for which reason the plane-stock at its mouth will not become swollen or crushed down in rear of the bit and below the surface of the face of the plane, as is the case with the plane for which Letters Patent of the United States were granted to me on the 9th of October, 1865, in which the strain or pressure on the bit C, by means of the screw I, is brought to bear on the mouth of the plane-stock, crushing down the mouth of the plane in rear of the bit, thus rendering my previous invention inoperative, and to remedy this defect prompted me to produce my present invention, which I claim to be an improvement on the former.

Having described my invention, what I claim, and desire to secure by Letters Patent, is —

The sliding box E, with clamping-screw I, and the forked prize-piece F, in combination with the cap-plate D and bit C, together with placing the same in the throat a, or forward end of the plane-stock, substantially as and for the purposes set forth and described.

In testimony whereof I have hereunto set my signature.

GEORG MÜLLER.
