THOMAS A. MANLEY, OF AUBURN, NEW YORK, ASSIG-NOR TO OHIO TOOL COMPANY, OF AUBURN, NEW YORK, A CORPORATION OF NEW YORK.

PLANE.

To all whom it may concern 1 Be it known that I, THOMAS A. Manner, a citizen of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to improvements in planes, and has for its object to provide novel, simple, convenient and effective means for adjusting the plane-frog longitudinally for facilitating the setting of the bit or plane iron in different positions in the throat of the plane body.

A further object is to provide novel and simple means for locking the frog after the same has been adjusted. And a particular object of the invention is to provide conven ient and effective means for adjusting and locking the frog without disturbing the plane iron and related parts.

The various features and parts and the operation of the same, will be fully set forth in the detailed description which follows, illustrated in the accompanying drawing, and then particularly pointed out in the claims.

Figure 1 is a side elevation and part section of my complete plane. Fig. 2 is a horizontal section, taken on line 2-2 of Fig. 1. Fig. 3 is a vertical cross-section, taken on line 33 of Fig. 2. Fig. 4 is a horizontal section similar to Fig. 2; showing a modification of the locking and adjusting means. Fig. 5 is a vertical cross-section, taken on line 5 5 of Fig. 4:.

Similar characters of reference designate like parts throughout the several views.

In the drawing, 2 represents the body of the plane, 3 the sole, 4 the throat or mouth, and 5 the cheeks or lateral guards which are formed integral with the body. The rear side or edge of the throat 4 is formed sharp and thin, and then the metal inclines upwardly and rearwardly at a slight angle for forming a smooth bearing surface 6 which extends across the upper side of the sole 3, to receive a correspondingly formed forwardly projecting portion 7 of the frog 8. The frog 8 consists of an irregularly shaped casting or part having a rearwardly and upwardly inclining top surface 9, for

receiving and supporting the plane iron or bit- 10, and having a substantially plain horizontal bottom 11, which bears and slides Specification of Letters Patent.

upon a comparatively long elevated step or portion 12, preferably an integral part of the body of the plane. The elevation or seat 12 is disposed a short distance rearwardly of the inclined bearing 6, and its top surface lies in a higher plane than the said bearing. The under side of the frog is correspondingly shaped, so that when the bottom 11 of the frog rests upon the elevation 12, the forward end 7 approaches close to the sloping surface 6.

13 represents like inwardly facing angular ribs or tongues formed horizontally on the cheek pieces 5, directly above the opposite sidc-edges of the elevated bearing 12, and 14 represents hollow corners or grooves formed in the opposite bottom corners of the frog, the said hollow corners preferably being formed right-angled, so as to clear the ribs 13 when the frog is moved to and fro over the body of the plane. The tongues or ribs 13 are triangular in cross-section, and preferably extend the length of the elevated bearing 12, and they are disposed parallel to said hearing, so that the frog, when operatively connected with the tongues, may be freely moved forward and backward in a true and'level plane. The tongues 13 are of sufficient length and strength to effectually hold the frog from chattering while the plane is in operation.

To hold the fro 8 in place on the base 2, and yet allow sai part to be freely moved to and fro for adjusting the cutting-blade or bit 10 relatively to the throat 4, the underside of the frog is provided with a broad transverse dove-tail groove or slot 15, in which is operatively fitted a pair of correspondingly shaped keys or locking members 1617. The keys 16--17 are disposed end to end, in the slot or way 15, and their combined length is slightly lessthan the breadthof the bearing surface 12 beneath the tongues or guides 13, the outer ends of the keys 1617 then project beyond each side of the bottom of the frog, as shown in Figs. 2 and 3. The outer ends of the keys 16-17 are beveled to correspond to the under-cut sides of the tongues 13 (see Fig. The abutting ends of the keys 1617 are provided with transverse concaves 18, the said concaves tapering toward the forward end of the frog.

19 represents a set-screw having a tapering point 19' extending beyond the threads,

the said point being tapered to correspond to the concaves 18 of the keys. The setscrew 19 passes through a threaded hole 20 formed in the rear portion of the frog (see Figs. 1 and 2), the hole 20 being arranged to bring the set or looking screw 19 into coincidence with the abutting ends of the keys 16-17. WVhen the keys l617 are brought together, the opposite concaves 18 form a tapering hole corresponding to the tapering point 19 of the set-screw. In practice, the length of the tapering end of the screw 19 is such that its point 19 normally projects part way into the tapering hole 18 between the ends of the keys. To look the frog in any adjusted position the wedge screw 19 is driven inwardly until its tapering end 19 spreads and forces the keys 1617 in opposite.directions against the beveled under-sides of the tongues or ribs 13 (see Fig. Any desired pressure or tension may be produced by means of the wedging of the screw 19 between the abutting ends of the keys 16 17. The said keys are preferably bro-ad enough to insure a firm bearing beneath and against the tongues 13, and will hold the frog rigidly in place. By the provision of the beveled ends of the keys 1617, when the screw 19 is driven inwardly for spreading said keys, they exert a downward pressure which forces and holds the frog rigidly against the bearing surfaces of the elevated seat 12. When the keys are made as shown in Figs. 1, 2 and 3, they are not liable to wear seats in the under-side of the ribs 13, which will interfere with the fine and accurate adjustment of the frog. In practice the key 16 is made longer than the key 17, so as to bring the abutting ends (18) to one side of the longitudinal center of the body 2. Under this arrangement the screw 19 may be readily manipulated without interference by the handle 21 or the bit adjustingscrew 22.

To assemble the frog and plane body, the frog is inserted between the cheeks 5 just forwardly of the tongues 13, and when brought to the proper position the project- .ing beveled outer-ends of the keys l617 may be entered underneath the tongues 13, after which the frog may be moved rearwardly until brought to the desired position. In constructing the plane body and the frog, the tongues 13 and the hollowcorners 14 are arranged so that the bottom 11 of the frog will rest firmly upon the upper surface of the elevated seat 12.

To adjust the frog to and fro longitudinally, I provide an adjusting screw 25 which enters a threaded hole 26 in the rear side of the frog 8 above the bottom 11. The screw 25 is preferably positioned at one side of the longitudinal center of the plane, so as to facilitate adjusting the frog without interference by the handle 21 or other parts of the plane. The screw 25 is held from longitudinal movement by means of a yoke 27 which forms the upright arm of an L- shaped bracket 28 which is mounted upon the upper side or face of the sole 3, by means of a screw or pin 29. The screw 25 has a circumferential groove 25 to receive the yoke 27. When the screw 25 is turned in either direction by hand or by means of a screw-driver, it will move the frog to and fro longitudinally on the base 2. The provision of the guide tongues 13 and the corresponding beveled keys 1617 Will prevent vertical movement'of the frog, as well as, lateral and longitudinal rocking of said part relative to the base, and this arrangement also insures the smooth, free and true horizontal movement of the frog on the ele vated bearing surface 12. The provision and arrangement of the tongues 13 and the locking keys or members 1617 will also effectually obviate the chattering of the bit when the plane is operated over hard or.

burly wood.

Figs. 4 and 5 illustrate a modification of the adjusting and locking parts, and also a slight modification of the form and arrangement of the bottom of the frog 8. lower side corners of the frog 8 are provided with annular grooves 14, which conform to the shape of the tongues 13 (see Fig. The locking means comprise a pair of like round keys or pins 30 and 31 which are loosely disposed in a hole 32 which passes transversely through the lower portion of the frog. The outer ends of the pins or keys 30 and 31 are beveled to correspond to the under-cut sides of the guide ribs 13, and their combined length is slightly less than the distance between the ribs 13, for permitting endwise adjustment, the same as the keys 16-17. The keys 30 and 31 are preferably the same length, and their inner ends meet at the transverse center of the frog. The abutting ends 33 of the keys 3031 are formed concave, and taper for wardly, similar to the construction shown and described for the keys 16-17. To look the frog 8 from longitudinal movement, I provide a screw 34 which enters a threaded hole 35 formed centrally in the rear-part of the frog 8. The inner end of the screw 34 is provided with a tapering point 36, which is arranged to enter the tapering concaves arranged in the abut-ting ends of the keys 30 and 31 for wedging them apart. When the screw 34 is driven inwardly the point 36 spreads the keys 30-31 and forces said keys laterally for tightly engaging the underside of the ribs 13. When the screw 34 is driven tightly between the keys, the frog 8 will be held from longitudinal movement. The arrangement of the dove-tail tongues 13 and the similar grooves 14 is The 1 such that, the frog cannot be moved vertically until it is withdrawn free from the ribs. To adjust the frog 8 to different positions longitudinally, the screw 84 is first loosened up, and then the frog may be shifted to and fro, and set in the desired position, by hand.

- The plane iron or bit 10 is provided with the usual guard plate 37, and is held in place by a cap 38, which is fitted with the usual clamping part 39.

40 represents a screw carried by the frog for engaging the cap 38. The adjusting screw 22 is employed for shifting the plane iron longitudinally on the frog, and a lever 41 is employed for adjusting the plane iron laterally.

The locking means comprising the keys and the wedge screws are extremely simple, yet affording powerful means for locking the frog to the frame. WVhen these parts are properly made and assembled, but a slight movement of the screws 19 and 34 in either direction will effect the rigid looking or the unlocking and freeing of the frog. The broad keys 1617 cooperating with the side ribs 13 tend to steady the frog during its forward and backward movements. The disposition of the screws 19 and 25 at or near the sides of the plane render the looking and adjusting parts conveniently accessible, and in view of the location and arrangement of these parts the locking and adjusting of the frog may be accomplished without disturbing the plane-iron or any other part.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is-
