` ppleation tiled, J'iijly 2,1, 11911 Serial No.. 639,815.

a citizen ofthel United States, residing at Milwaukee, in the county of Milwaukee and State. of- Wisconsin, have invented certain new and useful Improvements in Rod-Cub fuse.

ters, of whichy .the following isa specification. lhis invention relatesto improvements in rod cutters, the' primary object -of'which isto provide a machine of this type which is convenient and effective in operation, and Which will not get out oforderby continuous Other ,obje/*cts are 'to :so `arrange the cutting mechanisms that the machine will'be more powerful as `the resistance increases in ada vancing the cut and sothat the bar to be cut will not, be pushed awaybythe knivesv in the cutting action. v v l.

VStill further objects are toprovide peculiar operating meansas welly as advantageousv A vented from' `falling throughvby the lower means'to limit the movement of the jaws.

lilith Ithe aboveand other objects in view, this invention; consists inthe construction, combination, andA arrangement of parts, rall as lhereinafter more fully described, claimed andfillustrated iii the accompanying draw'- ings, wherein;l

Figure 1 isv ajside elevation of the rod cutter; Fig. 2'is atop plan viewthereof; Fig. 3 is a section on the line 3%3 ofFig. 1; Fig. 4 is a perspective view o'f'one of the jaw members; and'Fig, 'is a` perspective -view of the supporting member.

Throughout the followingdetail description, and `on the several figures of the drawings,""siniilar partsl are referred to byllike reference characters. y v

iRef'errng to the drawings, at 1 is indicated a basev having two pairs of pivot lugs or ears 2 projecting from-the upper surface thereof. Pivoted toone pair of said ears isa jaw 3, and co-acting with said jaw is a similar jaw lwhich is pivoted to the other pair of ears 2 by a pivot pin 5. Integral with andprojecting rearwardly` from said jaw members 3 and 4 are lugs 6 which, with -the base member 1, are adapted to limitthe movement of said ljaw members.

The means for operating the rod cutter consists of a lever 7 which is pivoted at 8 to the jaw member 3 and, which by a link 9, is

connected to the jaw member `4t for simultaneous operation of said jaw member. The link 9 is pivoted by a pin 10 to the lever l` slightly above its pivotal connection with 'the jaw member 3 and rests in a groove 11 in PATENT orrioia specmeeqnpf tettersrtent. .patented 09u17, 191.1,

the rear portion of a lug 12, ,whichvv latter is'4 integrally carried bythe aw member L1'. The link 9 which is of U-shaped formationis provided with -tlie bridge member 13located slightly in front of the lug 12 and adapted l to .engage said lu in separating the two jaw members by act-ion of thejle'ver-T.- f I .f The cutting elements consist of knives 15 which are mountedin recesses formed inthe jaw members 3/and4 and held in place by way down, then the cutting kedge projects' studs or bolts/161' Whenthe jawsare in slightly forwardly in a curved linev toward the opposite cutter member, thereby forming a a` comp.'tratively widev space between the upper portions ofthe-'knives to permit the entrance of the work', and which Awill be precurved portions of the knivesl.

' The lever 7 is provided with ya socket to receive a handle-17 'adapted for'operationl of the cutter, either manually-or byanacliine power.

'To prevent-the rod from bending -in the" .cutting operation thereof, a support 2O is ad- :justably mounted on the. base of each cutter member. This support is in the form of an angle-.iroi1,and is held in place by the bolts -16 which, as stated above, are also clamping' Ithe cutters. l y vIn operation, the :handle17 is `operated downwardly, thereby bringing the jaw menilbers toward each other by action of the link 9, as' clearly seen vin the drawing, and byV lifting the handle 17, the bridge portion 13 will engage with the lug 12, as a result of which the jaw members will separate; I t will be noted that the link 9 may be disengaged from the lug 12 for convenience in placing the work between the cutters which is found to be of great advantage when long bars are to'be cut/:v j

To facilitate the operation'of the machine, a .handle 18 is received. in a socket 19 integrally projecting rearwardly from the ljaw member 4.

It will be seen that in the action o f cutting a rod the upper portion ofthe knives will be moved toward each other at a greater rate of speed than the portions which engage .the work, said action resulting in the bar being :1'5 Having thus fully. described invention,-

I prolnptlycaughtbyl the cutters-,thereby pre' venting sidewlse slipping of the bar which 'may occur in an ordinary type'o'f rod cutter.

The construction of this machine is oi pe- 5 culiar advantage'in that aminimum weight..

"same work, 'and therefore this rod cutter is f especially advantageous as a pc .-table toel. as well as in a'machine shop -or manufacturing establishment. l

whatis claimed as new is-A s l. In a rod cutting machine, the combination ofa besa-jaws pivotally mounted at their lowerportions on said base, a levercar- 0 ried by one 'of said-jaws, anda link pivoted yto said-lever and connected with theother. jaw, whereby *on movement of the lever the jaws are lsimultaneously operated.

2. In 'a rod cuttingmachine, the combiv25. nation of a base, pair of jaws pivoted at their lov r ends to said baseknives carried by said jaws, a lever pivoted at one end to vthe upper portion ofl one jaw, and a link pv oted at one end tosaid lever and having' 201.115' other end engaged with the other j aw so that on vrfnoveinent of the lever the jaws will be simultaneously forced together.

3. In arod .'Lutting'finachine, the combina- I tion of a base,` a pair of jaws pivoted at their "lower ends to said base, knives" carried by said jaws, a lever pivoted at one end to the upper portion of one jaw, a link pivoted at one end to said lever and having its other end engaged with 'the other jaw so that on l40 movement of the lever the jaws will be simultaneously forced together, and a bridge -piece connecting the sides of the llnk. and movable against the jaw with which the link ytion of abase, a pair ofjaws pivoted at their lably engaged at oueside by the other end is engaged to separate the jaws aforesaid fn reverse movement of the lever.

4; In a lrod cutting machine, the combinaltion of a base, a pair. of jaws pivoted at theirlower ends to said base, a lever pivoted at its lower end to one of vthejaws, a link pivotall'y lconnected at one end to the lever ,and'lhavlng' its yother end detachably yengaged yover the other j aw, so that when the lever is moved in one direction the' vjaws will be simultaneously. forced together, a member Vcarried by -said link to engage said last mentioned jaw' to separate the Ijaws on reverse movement of .the lever, and knives carried by `'sala jaws.

5. Ina rod cutting machine, the combina` lower ends to the base, a lever pivoted at one end to. one of the jaws, a link of U-form pivotally connected at one end toy the lever, a lug carriedA bythe other jaw and detach-v of lthe link, a lmember connecting the sides of the link and adapted to. engage the opposite sides of thelug to separate the jaws, and knivescarried by the jaws. i

6. In a rod cutting machine, the combination of a pair of jaws, knives carried by said4 jaws, said knives comprising cutting edges: having straight portions adjacent to one end and converging portions at the other ends, said straight portions being substantially parallel when in open position, and means for actuating vthe knives to cause the stralght portions to move toward one anotherA faster than the converging portions.

In testimony whereof ,I aiiix'my signature 80 in presence of two witnesses.
