Application filed January 13, 1920. Serial No. 351,145.

To all whom t may concern.'

Be it known that I, WILLIAM C. BowLnN, a citizen of the United States of America, and a resident of Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Planes, of which the following is a specification.

My invention relates to improvements in planes and more especially to the adjusting means for the plane-irons, and consists essentially of a horizontally adjustable member to the forward end of which the planeiron is secured, and an oblique locking member for said first-named member, together with such other parts and members as may be necessary or desirable in order to render the plane which is equipped with the new adjusting means practicable, serviceable, and eflicient in every respect, the construction and arrangement of parts and members being such that said horizontally adjustable member and said locking member are readily accessible, all as hereinafter set forth.

The primary object of my invention is to provide a plane with adjusting means for the plane-iron, which means not only are simple in construction and operation, strong and durable and highly eflicient, but are readily accessible, so that theplane Vdoes not have to be taken down or any part thereof be removed, when it is desired to adjust said plane-iron forward or backward, and can be most conveniently operated to obtain the results desired, the application of a screwdriver at two freely conspicuous points being all that is required in order to make whatever adjustment is desired at any time.

Another object is to construct the plane in such a manner that the supporting member for theplane-iron is at all times held and guided in a fixed path which lies in the central, longitudinal, vertical plane of the implement.

@ther objects and advantages will appear in the course of the following description.

I attain the objects and secure the advantagesl of my invention by the means illustrated in the accompanying drawings, in which- Y Figurel is a longitudinal, central, vertical section through a plane which embodies a practical form of my invention; Fig. 2, a rear endelevation of certain of the new elements, the view being taken on lines 2--2,

looking in the direction of the associated arrow, in Fig. 1, and therefore being a cross section through the frame of the plane; Fig. 8, a-fragmentary detail in top vplan of the parts and members shown in the preceding view, and, Fig. 4, a detail inv side elevation of the link.

Similar reference numeralsdesignate similar parts throughout the several views.

Although l have illustrated a complete plane, it will not be necessaryto describe all of the parts thereof and their functions, but only those into combination or close association with which means enter and to which they directly relate.` I will first, therefore, point out or describe briefy the old elements in question.

rlhe `frame of the plane consists of a sole 1 and cheek pieces 8-3 as usual, and is provided with ordinary front and rear handles 4 and 5, respectively. 'A plane-iron or blade is represented at 6, and -a stiffener therefor at 7, the two being fastened together by a screw 8. The sole 1 has therein a throat 9 for the cutting edge of the blade 6. There are also a clamp 10 which has a slot 11 therein, a lever 12 to adjust the blade 6 longitudinally, with a thumb-screw 13 therefor,and a lever 14 with which to rock said blade and attached parts on their pivot, such pivot consisting of a screw 15. Thereis a longitudinal slot 16 -in the blade 6, and a longitudinal slot 17 in the stiffener 7. The screw the new adjusting 15 is received in the slots. 16 and 17 All these 'parts and members are oldl and well known bothstructurally and functionally Passing now to the new features it will be observed that there is a saddle vr18 on which is mounted a frog the sole 1,upon 19. vThe saddle 18 is located between the handles 4 and 5 and extends from cheek to cheek 8, and said saddle preferably has a central, longitudinal, raised portion 4which is exteriorly convex or. arcuate in cross section. The lbottom of the frog .19 is shaped to fit and ride on the upper surface of the saddle 18, and thus is affordedv a substantial support of suiicient` size lor 'area' to render said frog stable and prevent any sidewise or torsional movement on the part of the frog. frog is a downwardly and forwardly 1inclined proj ection 2O that bears at the bottom edge on the sole 1 behind or adjacent to the throat 9. Otherwise this frog is similar to At the forward end ofthe 55 f binder 28 in full, also the screw 22. The

`through the medium :tal

corresponding members in other planes, and' the screws 13 and 15 are tapped into said frog in the usual manner.

By adjusting the frog 19 back and forth on the saddle 18 the cutting edge of the blade 6 is shifted in the throat 9 in the manner and to the extent desired. By this means and in this manner the throat clearance may be varied.

Slidingly arranged in a bore through the longitudinal center of the saddle 18 is an adjusting rod or bar 21 which I term an adjuster. The forward end of the adjuster 21 is beveled to correspond with the inclination of the inner or rear side of the frog projection 20, and said projection is rigidly secured lto such beveled end of said adjuster by means of a screw 22. Fastened securely to the rear protruding end of the adjuster 21, by means of ascrew 23, is a link 24.-. An adjusting screw 25 is tapped into the back end of the saddle 18 at one side of the adjuster 21. The screw 25 has a head with an annular groove 26 therein to receive the end of the link 241- that is opposite to that which is attached to the adjuster, such end being bifurcated, as shown at 27 in Fig. 4l, to enter said groove. Obviously if the screw 25 be turned inwardly the adjuster 21 with the frog 19 will be` carried forwardly, of the link 24 and the screw 23, and if said first-named screw be turned outwardly said adjuster with said frog will be carried rearwardly, through the same medium as before. The handle 5 is in the central, longitudinal plane of the implement, and the adjusting screw 25 is a su'liicient distance from one side of said plane to permit a screw-driver to be applied to said screw without interference on the part of said handle. In other words, the handle 5 forms no obstruction to the use of a screwdriver Iin'adjusting the screw 25 to advance or retract the adjuster 21.

Locking means for the adjuster 21 is required, and the same consists of a binder inthe form of a screw 28 which is tapped into said adjuster from above. The head of the screw or'binder 28 is in the slots 16 and 17 in the blade 6 and stilfener 7, and from said head the shank of said screw extends downwardlyV and rearwardly through the frog 19, and a longitudinal slot 29 in the top of the saddle 18, into the adjuster 21. The latter is broken away in Fig. 1 to show the slot 29 is covered by the frog 19. The head of the binder 28 is accessible for a screwdriver through the slot 1l in the clamp 10. It follows, therefore, that the binder can be readily tightened and loosened by means of a screw-driver applied through the slot 11 I tothe'head of said binder.

when* the binder 28 is tightened a fora-,s the frog 19 on to the saddle 18 and the adsaddle, an adjuster juster 21 against the top of thebore in said Saddle for said adjuster, clamping the fixed and immovable saddle between said frog and adjuster or the two latter to the former, so that the adjuster with the frog and attached parts is held securely in place. Upon loosening the binder 28 the adjuster 21 can be moved freely to whatever extent may be necessary, since ample space for the movement in a direct line of said binder is provided by the slot 29. The binder also prevents or assists in preventing the adjuster from rotating on its axis, due to the fact vthat no movement sidewise of said binder is permitted by the sides of the slot 29.

To adjust the blade 6 in the throat 9, yit is lirst necessary to loosen the binder 28, and lthen the screw 25 is turned to advance or retract the frog 19 to the desiredextent. l fter this the binder is retightened.

More or less change in matters `of size, shape, construction, and arrangement of some or all of the parts of the plane may be made without departing from the spirit of my invention or exceeding the scope' of what is claimed.
