Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed July 25, 1912. Serial No. 711,586.

To all whom t may concern:

Be it known that I, JOHN I). GAGE, a citizen of the United States, resident of Vineland, in the county of Cumberland and Stat-e of New Jersey, have made a certain new and useful Invention in Planes; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a central vertical longitudinal section of the invention. Fig. 2 is a detail plan view of the plane stock. Fig. 3 is a detail plan view of the cutting plate and the guide clamp. Fig. 4 is a detail plan view of the cap iron.

The invention is designed to simplify and improve the carpenters plane, and particularly the block plane, in such wise as to provide advantages relating to its durability and useful facilities; and it consists in the novel construction and vcombinations of parts, as hereinafter set forth.

In the annexed drawings the numeral 2 indicates a plane stock; 3 a cap iron; 4 a cutting plate or bit, and 5 a guide clamp which is secured to the bit.

The plane stock is provided with integral inclined bearings 6 on the upper or inner surface of its bottom, in rear of the transverse slot 7 through which the cutting bit is designed to protrude, these bearings coinciding in their inclination with the beveled bearing 8 of the bottom, which extends to the acute rear margin of the slot. The front margin of this slot is formed by a transverse rib 9 which connects the side walls 12, 12, which are substantially parallel and form guides for the movement of the cap iron and bit. Connecting these walls, in the throat of the stock, above and in rear of the slot, is a cross bar or bearing 14, which is perforated and threaded for the passage of a strong set screw 15, the axial direction of which is designed to be substantially in line with that portion of the bottom which is adjacent to the acute edge of the transverse slot. The cutting plate or bit 4 is designed to rest on the bearings 6 and 8, and as the setting and securing def vices are located above it, this cutting plate can be disposed at a very low angle, suitable for a plane of the character indicated.

The cutting plate or bit is provided with the usual series of adjustment slots, and on the upper surface of this plate is adjusted and secured t-he holding or guiding clamp 5, which consists of a longitudinal base portion 16 and an upward projection or lug 17 which is provided with a bearing recess 18, open at its upper end and provided with an open-top slot bearing in rear to receive the neck of an adjusting screw 19. rIhe base of the holding clamp is provided with a threaded aperture for a clamp screw, extending through a slot of the cutter plate. The base of this clamp 5 has parallel sides, and it is designed to engage and slide in a parallel-side recess 20 in the bottom of the cap iron 3. The bottom of the cap iron is plane to fit neatly the top of the bit, at the sides of the clamp lug. The top of the cap iron is made with a beveled front wall 21, a sloping angular bearing 22 in rear of the top of this front wall and lateral bearings or lugs 13 in line with each other and designed to engage the transverse bar 14 of the plane stock when the cap iron is forced into position. The cap iron is provided with a middle opening or slot 23 for the reception of the clamp lug, and in rear of this opening is provided a transverse bear-- ing 24 in which is made a threaded opening for engagement with the adjusting screw 19.

The shouldered end of this adjusting screw engages neatly the bearing recess 18 of the clamp lug 5, so that the adjustment of this screw moves the clamp and cutter plate backward or forward with reference `to the cap iron, which therefore forms the principal or purchase element for this adjustment.

In a plane of this character the cap iron is designed to be provided with a bowed handle portion or push bearing 25 of suffi cient height and span to protect the adjustf ing screw and allow removal of the cutter and clamp.

The front of the cap iron is of proper height to pass easily under the transverse bar or bearing 14 of the stock. And when the cutting plate, properly and` securely fastened to its guide clamp, is provided with its cap iron in engagement with the adjusting screw, a combination of parts is formed which is designed to be placed on the bottom inclines of the stock and, if the set screw 15 is raised, will easily slide forward to position. In normal position the bearings 13 of the cap iron abut against the bar 14 of the stock, and the sloping bearing 22 lies under this bar. The screw 15 being now set down firmly against this sloping bearing, operates to drive the cap iron forcibly7 home against the transverse bar or bearing 14, and to clamp the cap iron firmly in place on the cutter plate. Adjustment of the bit is easily effected by means of the adjusting screw of the cap iron.

This plane is designed to be in a manner self-setting as its capV iron and plane iron fit together accurately beforehand, and when simply laid in place will slide forward to true position. I/Vhen the cutting plate is properly secured to its guide clamp, no adjustment of the holding or setting parts is required, except in regard to the operation of the set screw and the adjusting screw. The simple devices of this plane can be taken apart and put together exactly as they were in a few seconds.

The setting and holding devices of the plane are placed above the cutting plate, in such wise that the latter may be arranged at as low an angle as may be required. The cap and plane iron are forced .to accurate position and held therein by a single set screw, and without other care and attention than is required to turn the screw forcibly home.

In taking out the bit and cap iron no movement of the adjusting .screw is required. The set screw being loosened up sufficiently, the cap iron, guide clamp and cutting plate will .slide back and, without moving the adjusting screw, the cap iron can be lifted from the cutter plate. Upon replacing the parts without adjustment of the screw of the cap iron, the bit takes its former position with relation to the cap iron accurately, so that when placed in the stock the cap iron will take normal position therein and there will be no change in its shaving adjustment.I It is designed to provide'in this plane practical operating parts which will when once adjusted always go together in accurate and true position with relation to each other to secure the same thickness of shaving without further operation of means of adjustment.

Having described the invention, what I claim and desire to secure by Letters Patent is:
