Be it 4known that I, W.B. GLOVER, of Boston, inthe county of Suiolk'and Statey of .Massachusetts, have invented a new and valuable Improvement 1in Planes; and I do hereby de- "clare that the. following is a full, clear, and

,exact description of the construction and operation of thel same,preference being .had to vHita-'annexed drawings, making a part of this specification, andtothe letters and figures of reference.markedthereon.'l i

ylligure 1 of the fdrawings is a representation of a centralvertical longitudinal section of my. invention; Figa .2 isa froniviewof the bed- ',p'lateand slide. Fig'.13 is a front 'view of the lane-bitand its regulating-key. Fig-4 is a and 7 are detals,l` I

My invention relates to planes; and it eo'nf 'sista mainly, in the construction 'and novel arrangement of devices, whereby the planebitfcan be regulated at will and'with certainty. The letter A of the drawings designates the" plane-stock, of wood or iron.. To this is fitted a bed-piece, B, which is secured rmly to the stock by' means-of. screwsa a.'

.Upon .the bed-piece is arranged'aslide, C,

'having Aa wedge-like end, c, whichv is pressed forward by the inclined .portion c of .the bedpieee when the slide isrlepressd, therebyadvancingj the plates which composethe planebit andlessening the throat-opening.. .When

-it is desired to widen the 'throat to admit 'larger shavings, the lslide is drawn up by means of the lever D, -pivoted to the bed-piece B, as

shown.' The 'slide 'is .kept close to` the bed-v,

piece', when elevated, bymea'ns of.its.tongue c', which is arranged to work in an inclined slot, l, in the bed-piece. The leverlD therefore operates, through the slide C, to regulate .the

,size oi' the throat or opening through' which the shavings' pass.

v1: designates the planebit, which is secured to its cap E by means 'of 'a screw in the ordinary manner. Through the cap E are formed two openings-one yabove the screw and the other below. A notch, fb, is formed at the side.

E of the upper opening,and in this notchworks :the toe n of the' lever "o1- key G, whichis' pivoted. eccentrically on the pin s, formed on the.

shoulder-Ffa part ofthebedlplate: The shoulder -F l'also servesito keep the'plane-bit righlfA as it lits in the longitndinal slot thereof. -:.fB'y

` moving the handle of thelever Gto the right the plane bit is lowered, and, reverscly, a

movement to the left will. elevateit.'

' 'The parts arebound together bythe vplate H, curved, in form, andarranged .so that its ends only bearupon ',:tfie cap. A recessie. I formed in .its 'upper .en'd "to .receive the ex- 'panded end of the keyG, and a circularide.

'pression is madein its face, .thebottomoffwhich is formed into two semicircular inclined planes, r 1', arranged to operate in connectlon wlth two similar inclined planes, tt, formed on thennder side of thelbinding-key K. This binding-key is secured to the bed-plate by means of the screw L, fornied with a'large head, which is passed the direction of this notch unjtil the neck is embraced by it. .A slight turn of the key- K',

causing the inclined planes to act upon each other, will bind all the parts tightly together'.

ancesls capable of being operated in a satlsfacr. 'tory manner. N o violence-as striking with a hammer orl mallet-is needed. `lf the throat requires alteration,' thebinder isloosened :by --a` turn of the .key K, andthe slide C then re ff latedby the lever D; turn offtheke'yK will make all tight jag'ain. The key G" regulates the bite ofthe plane-bit, andon account of its`great leverage -will operate withut vthe necessity of previously loosening the binder". What Ielaim as .my invention', and desire t secure by Letters Patent, isfl. The lever or key-G, .pivoted tothe bed'-v plate, and arrangedto engage with the-cap iron E, thereby'regul-atin g the bite of theplanebit, as specified. l l v '-2. The slide C, operated byfneans of the lever or key D, in combination witlthe ledplate B, 'having an inclined plane, e, .all con-- structed and arranged to regulatethe s ize of the lthroat of the plane, as specied. "3'. Attached :to the bed-platen, the-10am leverK, in combinationwith the semicircular inclined planes r lrof thebenhbnding-plate H, In testimony that I claim theabove I have all constructed and arranged to operate as, hereunto subscribed my name in the preqence spcciiied. of twowitnesses. l
