My invention I relates particularly to printing ink knives such as are used'about printing presses for transferring ink. to and i from the ink fountains of the presses and for stirring the ink in the fountains to maintain the ink in a uniformly mixed condition, al-
'. 1 though not limited to-these uses alone.
- r The main object of the invention'resides'in the'provision of a knife ofthe abovetype l@ which is particularly efliective in mixingthe in the ink fountains of printing presses, at the same time being adapted for all of the uses to which such knives are put.
' With this object in view my invention consists in certain features ofnovelty' in the construction, comblnation and arrangement of parts by which the-said object and certain "other objects, hereinafter appearing, are ef v v partsin the several views.
, dle and shanks; f
fected, all asfully described with reference to the accompanying drawing and more particularly pointed out in the appended claims;
In the said drawing I V I Figure 1 is a side elevation of a knife em-- bodylng my invention, and I Figure 2 is an edge elevation of the same. Like characters of reference indicate like i ,7 Referring to the draw1ng, 1 designates a .,.30I sual handle, and fixed on the handle and extending therefrom inadj a'cently spaced edgewise relation are two blades2 and 3, the blades being fixed inthe handle by means of shanks 4 thereof being'en'gaged in a slot in the handle and secured therein" by rivets 5 1 passing throughregiSteringhOles in the han- The outer longitudinalredge 6 of the blade 4 o 2 is straight and this blade has a straight "transverse outer end edge? for use in scrap- I ing out' ink containers, ink fountains and the like.
The inner longitudinal edge of the blade-2 V is sinuous, as' designated at 8, and the longitudinal edges of the blade 3 are sinuous, as designated at 9, the inner longitudinal edge of the blade 3 preferably corresponding with I the inner longitudinal edge 80f the blade 2. r
' Ink is mixed in the ink fountains of printing presses by passing the blades of the. knife I I substantially facewise through the ink, it being observed that the blades provide four f edges for the ink topassover, thus affording a quickmixing of the ink, the three sinuous I edges 8 and 9 of the blades further aiding in the mixing. I V i I The blade '3 ispreferably narrower and 1 consequently more flexible than the blade 2 so that under the pressure of the ink in the mixing thereof the blade 3 is flexed out of its nor-' 'mal relation with the blade 2 thus widening 0,
new and desire to secure by Letters Patent thef' I following 1. In a printing ink knife r the like the combination of two blades mounted on a handle and extending therefrom in adjacently, spacededgewise relation,one of said blade SI having its outer longitudinal edge straight' and having its inner longitudinal edge s1nuous, and the other blade having both ofits longitudinal edges sinuous.
2. In a printing ink knifeor the like the 5 I i I combination of two blades mounted on a bandle and extending therefromin adjacently spaced edgewise relation, one of saidblades having its outer longitudinal edge straight and having a straight transverse outer-end" edge and having itsinnerlongitudinal edge I sinuous, and the other blade having both of I I its longitudinal edges sinuous.
3. In a printing ink knife or the like the combination of two blades-mounted ona handle and extending therefrom in adjacently spaced, edgewise relation, onejof said blades 7 having its outer longitudinal edge straight and having its inner longitudinal edge sinu- I ous, and the other blade having both of its longitudinal edges'sinuous, one of said blades being more flexible than the other. 7 v I V 4. In a printing ink-knife or the like the combination of two blades mounted on a handleand extending therefrom in adjacently 100,
spaced edgewise relation, one of said blades having its outer longitudinal edge straight and having a straight transverse outer end edge and having its inner longitudinal edge sinuous, and the other blade having both' of its longitudinal edges sinuous with the inner longitudinal edge thereof corresponding with the inner longitudinal edge of the other blade and being more flexible than the other blade.
In witness whereof I hereunto afiix my sig- I nature this 3rd day of December, 1928.
