COMBINATION-PLANE.

SPECIFICATION forming part of Letters Patent No. 538,937, dated May '7, 1895.

Application filed August 9 1.894.

To all whom it may concern: A

Be it known that LJACOBV. TRIPP, of Salt Lake City, in the county of Salt'Lake and Territory of Utah, have invented a new and Improved Combination-Plane, of which the following is a full, clear, Vand exact description.

The object of the invention is to provide a new and improved plane, which is comparatively simple and durable in construction, arranged for universal adjustment to enable the operator to conveniently plane straight or curved work, such as stair rails, on all sides, and for molding, litting, plowing, tonguing and grooving, rabbeting and other purposes, also to form beads, fillets, &c.

The invention consists principally ofa stock adapted to receive a removable wooden sole piece shaped to conform to the curved or straight surface to be planed. n

The invention further consists in a bithaving gear teeth adapted to be engaged by asegmental lever, for shifting the said bit into proper position.

The invention also consists in an auxiliary guide stock pivoted on an adjustable arm held on the main stock.

The invention also consists in certain parts and details, and combinations ot the same, as will be. fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views.

Fig. 13is a sectional plan View ot' the same on the line 13 13 of Fig. l2. Fig. 14 is an inverted plan view of the bit. Fig. 15 is a plan View ofthe same. Fig. 16 is a face view of a combination quick cutter and blank. Fig. 17 is a face view of a modilied form of fastening for the quick cutter, and Fig. 18 is a sectional plan View ot the same ou the line 18 18 ot Fig. 17.

The improved plane is provided with the metallic stock A, having an integral handle A', and a bit plate A'2 extending in an inclined direction, as plainly shown inFigs. 1 and 3, and fastened by screws or other means to the stock A and handle A. On the under side of the stock A, is adapted to be secured by screws or other means, a sole` piece B, having its bottom made in various shapes according to the article to be planed. The sole piece is made of wood, and is shaped at its under side to correspond to the shape ot the article to be planed, 'as willv be readily understood by reference to Fig. 1,or is made straight atits under side for planing straight surfaces of different shapes, as illustrated in Fig. 12.

On the lower end of the cap C is secured a sole piece B', forming a continuation of the sole piece B, and shaped according to the article under treatment, that is, either curved at the under side, as shown in Fig. 1, or straight as illustrated in Figs. 9 and 12. The pressure plate or cap C for the plane, is adapted to engage and hold the cutting bit D on the bit plate A2.

In order to shift the bit D, I form the top surface thereof at the upper end with rack teeth D adapted to be engaged by the teeth E' of a segmental lever E, formed with a slot E2 adapted to engage a pin Cextending transversely in the pressure plate C, and through an aperture C2 therein, as will be readily understood by reference to Fig. Now when the pressure plate C is in place, the operator inserts the segmental leverE in the aperture C2, so that the pin C forms a fulcrum for the said lever, and the teeth E of the latter engage the rack teeth D of the bit D. When the operator swings the lever E either up or IOC curely in position.

down, then the teeth E' shift the bit D down or up, so as to adjust the cutting edge of the bit according to the under side ot' the sole piece B. After proper adjustmentis made of the bit D, then the segmental lever E is again removed from the aperture C2 and the pin C. The pressure plate or cap C is held from sliding by dowels F, F', which project at right angles from the bit plate A2. See Fig. 3. To clamp the bit in place on the bit plate A2, I provide a screw rod F2, secured inthe bit plate A2, parallel to the dowels F F. The screw rod F2 is provided with the smooth piece F3, extending through the bit slot D2 and the cap C. The reduced end F4 of the screw rod F2 engages a removable block G, titting under the head F5 of the said screw rod, and on the sides of the said block G is fulcrumed a cam lever G', formed near its outer end with an opening G2 adapted to fit over the outer end of the dowel pin F', whenever the said cam lever is in a closed position, as shown in Figs. 1, 3, and 12. The cam is formed on the fulcrumed end of the lever G', and engages a wealing plate G4 held on the pressure plate C, so that when the lever G is swung inward, then the cam portion ot the said leverpresses on the Wearing plate G4, to raise the block G, and to securely press the latter against the under side of the head F5 of the screw rod F2, whereby the pressure plate C is firmly pressed inward onto the bit D, to clamp the latter se- The wearing plate G4 can be dispensed with in case the cap C is made of a hard material.

When the lever G is swung outward into the position shown in dotted lines in Fig. 3, then the cam end of the lever releases the block G from pressing on the head F5, thereby loosening the pressure plate C sufficiently to remove the cutting bit I) as may be desired. In order to properly guide the bit D, I provide the under side thereof with a longitudinal recess D3, see Figs. 3 and 14, engaged b v a lug A8 formed or secured on the bit, late A2.

On the lower end ofthe cap C, and butting on the face of the bit D, is arrange an adjustable plate C4, formed with a longitudinally-extending shoulder C5 fitting into a correspondingly shaped groove in the cap or pressure plate C, as plainly shown in Fig. 4. A screw C6 serves to hold the adjustable plate C4 in place on the pressure plate C, the said screw passing through a longitudinally-extendingr slot CT formed in the adjustable plate C4. By the arrangement described, the plate C4 can be readily adjusted on the pressure plate C, by loosening the screw C6, and then shifting the said adjustable plate C4 so that its lower end is as close down to the cutting edge of the bit as desirable, to permit of cutting in cross-grained wood without danger of tearing it or leaving a rough surface.

On the rear face of the stock A, is held adjustably a block H, provided with an obliquely-extending slot H', through which passes a screw H2 screwing in the stock A, as'

indicated in Figs. 6 and 7. A shoulder H, see Fig. 10, formed on the back of this block II engages a correspondingly shaped groove A5 in the rear face of the bit plate A2, the said groove A5 being arranged parallel or in alignment with the slot I'I, so as to permit ot shitting the block H in an oblique direction ou the stock, as required. On the back of the block II is formed a vertical recess or groove H2 (see Figs. 2 and 5), in which is held adjustable a quick cutter or bit I, for cutting the sides or edges of the wood under treatment, as plainly illustrated in Figs. 5 and 7. The quick cutter I, may be held in place ou the block H, either by a screw I', as shown in Fig. 5, or by making it dovetailed in cross section and clamping it in position at one edge by a cap H7 adapted to be fastened to the block H by a screw H8, as shown in Figs. 17 and 1S. Instead of the cutter or bit I, I may place a blank 13 in the said groove Il, seo Fig. 12, and the cutter I and blank I2 may be combined in a single piece, as illustrated in Fig. 1G. The blank I3 is provided with a row of apertures, one of which is adapted to be engaged at a time by the set screw I', but the blank may also be held in place by the cap H7 above mentioned. This blank I2, when used, prevents the shavings from accumulating in the planethroat and choking the plane, and is especially serviceable when cutting deep slots or grooves with the bit D, or other bits that may be used.

On the lower end of thebloclt H is pivoted at J, the auxiliary guide stock J, extending transversely, as plainly shown in the drawings, and carrying at its lower end an adjustable plate K, engaged by a setserew K passing through a slot J2extendiug longitudinally in the auxiliary guide-stock J. By this arrangement the plate K can be adj usted laterally in the guide stock according to the thickness or width of the wood under treatment. The screw K is adapted to engage one of a series of apertures K2, K3, K4, in the plate K, so as to increase the range ot' adjustment of the said plate K on the said guidestock J.

On the front end of the plate K is arranged a foot-piece K5, made of wood or other suitable material, and shaped to correspond to the shape ot the wood to be planed, as indicated in Figs. 5 and S. The foot-piece K5 shown in Fig. 8 is more especially designed for use on twisted and crooked work. The foot-piece K5 is opposite the front sole-piece B', secured to the underside of the shavings cup C, as will be readily understood by reference to the dotted lines in Fig. l, the said foot-piece also extending rearwardly a suitable distance, so that its rear end is about opposite the cutting edges of the bits D and I.

On one side of the auxiliary guide stock J is 'fitted to slide transversely, a block L, having a longitudinally extending groove L2 engaged by a setscrew L screwing in the auX- IOC IIJ

iliary guide-stock J, the screw L thus admitting of a right or left movement of the said block, and the screw is adapted to engage one of a series of tap apertures J3 in the auxillary guide-stock J. See Fig. 11,. A link N, pivotally connects this block L'with a stud N secured on the block H, so that the upward and downward swinging motion of the auxiliary guide-stock is limited, but any desired adjustment can be made by adjusting the screw L in one of the series of tap apertures J3 in the auxiliary guide stock J. By this arrangement the auxiliary guide-stock J can be moved in a tilted position according to the Wood under treatment, or the main stock A may be inclined, as shown in dotted lines in Fig. 5.

Now it will be seen that with the device described, almost any desired form of molding can be planed, as the tool is universally adjustble for all kinds of work of any class desire Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
