in the cuttingioperation and in which thel cutter blade is mounted so as to be protected against injury and against injuring those.

15 using it.

Anotherobject .is to so construct a device of this character that the parts may be readily separated for repairing or furnishing a `new blade when suchbecomes necessary.

In carrying out these objects, the invention is susceptible of a wide rangeof modification without departing from the spirit or sacrificing any of the advantages of' the claimed invention; there 'being shown in the drawings for illustrative purposes a preerred and practical form, in which:

Figure 1 representsA a perspective view of a portion oi acounter showing this improved cutter in operative position; 3D

ber of the cutter, with the blade shown in ydotted line; l

Fig. 3 is a similar ber of the cutter; v y y Fig. l is ay transverse section taken on the line 4-l of Fig. 1 ,"and Y Fig. 5 is a similar view talien on the line V 5f-5 of' Fig. 1. `4 y In the embodiment illustrated the cutter e@ 1() constituting this invention is shown lmounted on one endof a table or count-er l which has a pin or rod 2 extendin g upwardly therefrom preferably near the corner to rcceive and rotatably support a ball 3 of twine et such as is ordinarily used in stores for tying up packages.

The cutter 10 is composed of two members 11 and 15 slidably and separably connected and between which is designed to be mounted E? the cutting blade 20. This blade 2O as shown view oi the other memis in the form of a safety razor bladehaving cutting edges along both top and bottem so as to be reversable when desired and pped with apertures 21 to receive out struck tongues-12for1ned on the body of the member 11 andwhich face in opposite directions as shown clearly in Fig. 2. so that when the blade iszmounted thereon it will be heir. against sliding movement. p. y

The member 11 is designed-to` be attached Vto the counter or othersupport by means of screws 22 passed through apertures 18 in the body of the member 11.` lnturned flanges 14 are formed along the side edges of the memberll which is preferably struclziout of sheet metal and these flanges form guides to slidably receive the member 15. A longitudinally extending slet-like opening 23 is formed on one edge of the member 11 and has a mouth 2li opening through said edge and forms in connection with a similar opening 26 in the member 15 provided with a mouth 27 a chamberto receive the cord A1 to be severed.

The plate or member 11 is made wider at l its front end than at the rear oi the opening 23 and the outlet or mouth 2e of said opening 1s located at the junction of the wider v i portion of this plate with the narrow portion Fig. 2 is a detail perspective otono mem-pk of the plate asis shown clcarlyin Figs. 1 and 2. Y

Member 15 is struck out oi: a sheet of metal with the body portion thereof outwardly bulged for the greater portion .of its length as shown at 16, saidbulged portion gradually merging at its inner end into the body of the plate. This bulge-d -portion operates to space the members apart'during their slidin@` engagement3 the edges of said plate 15 being adapted to extend under and be guided by the inturned flanges 14 of the member 11. The wider portion'ot the plate 15 is designed to slide in the flanged edge 2510i the wider portion of the plate 11.

The upper edge of the wider portion `of late 15 is also'rprovided with an open` slot 26 provided with `a mouth 27 which'registers when the plates are in extreme retracted position, with the slot 23 of plate 11 asis-shown. clearly in Fig. 1. This slot 26 as above de- (ffl scribed has a mouth 27 at its inner end which registers with month 24 of plate 11 and is designed to receive the cord to be cut by the blade 20 which is clamped between the members 11 and 15 with its cutting edge pro- Yplate to slide freely without contacting or bindinef against said screw heads.

PTJ h l b In the use of this cutter the parts being assembled as shown in 1 and a ball of cord placed on the pin 2 with the free end 4lofsaid core loose it will be understood that this cord end may be used to pass around bundle and tied; then bv simply inserting the portion beyond the tied bundle in the opening `in the upper edges of the plates entered throiigli the registering mouths 24 and 27 the cord may be moved downwardly against Vthe sharp edge of the cutting blade 20 and quickly severed.

Then it is' desired to reverse the cutting edge of blade 2O all that is necessary is to drawoutwardthe plate or member 15, discngage the Ablade from the tongues 12, reverse it and again reengage it and then replace the vmember 15 which kwill clampingly hold said blade in operative position again ready for use.

f rlhe extreme simplicity of this deviceand the fact that old safety razor blades may be used to form the severing element2() renders the upkeep of the device practically nil. Moreover with the blade housed between the two members 1l and 15a-ind having the cutting edge thereofextended upwardly from the lower walls of the registering openings said bladeis protected against being injured itself and also against Contact with persons using it.

lVitliont further description it `isvtliought that the vfeatures and advantages of the' invention will berreadily apparent to those skilled inthe art,r and it will, of course,rbeV

understood that changes in the form, proportion and minor details of constructionv may be resorted to, without departing from the spirit of the inventionr or its scopeas claimed.

I claim:

LA cord cutter comprising Ia. pair of clamping plates arranged onev on the other in sliding relationand having means tojhold Qthein against separation, said plates each having aiecess opening through one side edge and extending longitudinally of the plate, said recesses being adapted to register Qwhenthe plates are brought to -a predetermined position,l a cutting blade clamped between said plates with its cutting edge extending iiito said recesses, one of said plates having a transvez sely arran ged tubular ineinber to forni a hand grip.

2. A cord cutter comprising a pair of clamping plates adapted. to be arranged one on the other and to slide longitudinally in relation to each other, one of said plates have ing inturned flanges along its side edges to -forin guiding means for the other, both of said plates having one end ina-de wider than theother and said wide ends provided near one edge with longitudinally extending open slots, the openings in said slots being arranged at thel junction of the wide portions withthe narrower portions of the plates, and a blade to be clamped between said plates with oneeege projecting into said slots.

3. A cord cutter comprising a pair of clamping plates adapted to be arranged one ontheother and to slide longitudinally in relation to each other, one of said plates having inturned flanges along its side edges to forni vguiding means `for the other, both of said plates having one end made .wider than the otherand the said wide ends provided near their upper edges with longitudinally extending open slots', `the openings in said slots being arranged at the-junction of the wide portions with the narrower portions of the plates, said open slots being adapted to registerwhen the plates are in operative position, a blade to be clamped between said plates with one cutting edge projecting into said slotsnand means forsecuring. one of said plates toa support.

ll. A cord cutter comprising a pair of clamping plates adapted to be arranged one von the other and to slide .longitudinally in relationto each other, one of said plates having intnrned flanges to forni guiding means for the other, both of said plates having one end made wider than the other and said wide ends provided near their upper edges .with

.longitudinally extending slots open at one end, the openings in said slots being arranged at the junction of .the wide portions .with the narrower portions of the plates, said open slots beingadapted to register when the plates are in operative position and to form a blade seat, means for seciiringone of said plates to a support, and an outwardly bulged poi'- tion inr onel plateto adapt it to move freely over the securing ymeans of the other plate without contactingthem.
