gL a lslightly different cono PLANE 1925. Serial No. 12,492.

Referring"V primarily to Figs. 1,2 and V3, it will be noted that aplane has been ilustrated v which includes a body having a bed 5, a knob 6 being secured in position at the front of the bed, and a handle 7 being'associated with the rear end thereof. This bed is, in the usual manner, formed with. an 'opening or l throat 8, into which the lower end of a knife assembly extends. n

The latter, if desired7 may include a blade 9 provided with a cap-plate 10, these units being secured against relative movement by rocked by a shifting lever'lQ, `In the present yinstance all of these units are carried by a frog'having a main body-portion 13 coml' prising aninclined bit-bed or seat, a rea-r projectlonwith an nndjerfa'ce or seat, the bed ortion termmatin "in a face 23 eno'am ing with'the plane bed, the frog beingladapted tobe secured to the bedv 5,. Y y

In Aorder to effect suchattachment a rib 14 extends Vfrom theupper face `of the plane bed, andbetween the side walls 15 ofthe latter. This rib is formed,in the present instance, with three transversely-extending screw-threaded bores. within which the fshanks of correspondingly threaded members are disposed. Thecentral member 16 terminates in a grooved and slotted head 17 extending beyondthe rearv face -of the ribV 14. The two outermost screw-threaded members 18 and 19 have their ends extending beyond the'transverse faces of the rib, and adjacent their rear endsvvare preferably formed with slot 'or groove, sothat they `maybe turned by .means kof a screw driver `or Asimilar implement. A screw 2O ls-carrled by the frog '13, and serves to secure a fork 21`insi1c`h position that its armsextendwltlnnthe groove f ofthe headV 17,an`d, Consequently, upon this `headbeing turned'to move the shank 1G relagV moved lontivelyto the frog the `latter will be gitndinally of the bed 5.

jThe bed of the plane is in this exem liica- "tion formed with a step or bench 22 a jacent;

, noted that the frog body is extended as at 24; so that it may bear adjacent its forward edge portion against the face of the step 22. Similarly, if desired, the upper edge of the rib 14; may be provided vwith guiding-lips 25 vadjacent the side edges of a second extension 26 forminga part of the frog body, and thus the movements of the frog will be properly confined with respect to the plane body. Vilhile this movement, as in Figs. 1, 2 and 3,

' is in a plane parallel tothe upper face of the tool body, it is obvious that, if desired,-as in Fig. t-the forward edge of the frog might be extended as at 29v so asV to be capable of projecting into the throat 8; and the rear edge of the latter might be beveled as vat 30,- the under face of the frog which cooperates therewith being correspondingly beveled. In athis instancerthe upper face ofthe rib 31 corresponding to the rib 14 is also beveled as at 32, and that facerof the frog which cooperates .with this portion is also correspondingly surj faced.

The extended portion 24 of the frog is continued in the form of va rearwai'dly-projecting portion, which has its upper surface inclined as at 27A to cooperate with the correspondingly beveled end-portions 28 of the screws 18, 19.

VJ ith reference tothe construction shown in Figs. l to 3, it will be understood that the plane parts are assembled in the usual inanner, and that the size of the throat opening .may be readily diminished without disturbing the vsettingV ofthe blade by simply lprojecting the screw 16 within its bore, thus advancing the frog body, together with the parts associated therewith. Thereafter, by projecting the screws 1S, 19 the inner ends of the latter will'bc' forced into intimate contact with the upper face 2T ofthe lfrog extension. y `During the movement of the frog it will 'be Yobvious that it willj-beconlined to aproper path by virtue of the guiding expedient herevin suggested, and by the use ofthe screws 18,' i .19 it will be apparent that a retraction and raising of the frog will. be prevented, due to the fact that the inclined cooperating faces 27, 28 `will coact to prevent such movements.

In theY forni of tool illustrated in Fig. 4 rit will be obviousthat in order to constrict the size of the throat opening the same procedure willbe resorted to as in connectionwith the ,tool afored-escribed, but by means of this latter construction it will also be apparent that the rear face of the blade will be supported ata point immediately adjacent its cutting edgeincident to the frog` extension 29. It

willbe understood in connection witli'the 4typesfof devicessliown in Fig. l that simuli taneously` with the adjustment of thethroat opening the blade will be extended or retracted, this being true incident to the surfaces 30-32- If, however, it is desired to vary the throat opening without effecting a consequent projection or retraction of the cutting edge, this may readily be accomplished by ship of thesame to the frog, and during such adjustment all units will be properly guided so that itwillnnot Vbe necessary to resort to vmany complicated adjustments, and at least a' partialv disassembly of the tool, in order to reset the parts. Obviously, the size of the throat might be increased by simply reversing the rorder of operation which has been previously described, and when rthe parts have once been locked it will be obviousthat a shifting of the saine is virtually precluded.

From the foregoing it will beappreciated that the objects of thel invention have been accomplished, and since certain 'changes may be madein the above construction, and different embodiments of the invention-could be made, without departing from the scope thereof, it is intended that all lvmatter contained in thevabove description, or shown Vin the Vaccompanying drawings, lshall Abe interpreted as' illustrative and not in a limiting sense.

It is also to be understood that the follow-y A.ing claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.V Having described my invention, what l into said throat, a rib adjacent said throat and `having its upper edge beveled in a plane substantially corresponding tothe beveling of thethroat edge, the frog adjacent a point at which it contacts with said rib being correspondingly surfaced, said frog presenting ka rearwardlyfextending surface inclined atv an angle to said first-named surfaces, and a screw carried by'said rib having an end tapered to correspond to said latter surface and contacting therewith for preventing n movements of said frogl relatively ,to said bed.
